DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] The work assistance system and the work assistance method will be described with reference to the drawings.

[0026] [Configuration common to the first to fourth aspects] FIG. 1 is a block diagram showing a configuration of a system including a work support system 300. FIG. 2 is a diagram for explaining an outline of the work support system 300. The work support system 300 shown in FIG. 1 and FIG. 2 has a configuration common to the work support system 300A according to the first embodiment, the work support system 300B according to the second embodiment, the work support system 300C according to the third embodiment, and the work support system 300D according to the fourth embodiment. Before describing the details of each of the work support systems 300A, 300B, 300C, and 300D, the work support system 300 having a configuration common to these work support systems will be described.

[0027] The work support system 300 is a system for improving the psychological state of an operator MP when working using a construction machine 100. The construction machine 100 is an example of an operation target in the present disclosure. As shown in FIG. 1, the work support system 300 includes a controller 50. The controller 50 includes a computer including an arithmetic processing unit and a memory, and controls the operation of the work support system 300. This also applies to the work support systems according to the various aspects described below.

[0028] The controller 50 includes a command content determination unit that determines the content of a psychological state improvement command by using the psychological state information. The command content determination unit is realized by the arithmetic processing unit executing a control program stored in the memory of the controller 50.

[0029] The psychological state information is information correlating with the psychological state of the operator MP at least one of when operating the construction machine 100 (operation target) and when operating the simulator 200 of the construction machine (operation target). In other words, the psychological state information may be information correlating with the psychological state of the operator MP when operating the construction machine 100. The psychological state information may be information correlating with the psychological state of the operator MP when operating the simulator 200. The psychological state information may include information correlating with the psychological state of the operator MP when operating the construction machine 100 and information correlating with the psychological state of the operator MP when operating the simulator 200.

[0030] The psychological state may be the impatience (degree of impatience) of the operator MP when operating the construction machine 100 or the simulator 200. The psychological state may be the fatigue (degree of fatigue) of the operator MP when operating the construction machine 100 or the simulator 200. The psychological state may be the concentration (degree of concentration) of the operator MP when operating the construction machine 100 or the simulator 200. The psychological state may be the irritation (degree of irritation) or impatience (degree of impatience) of the operator MP when operating the construction machine 100 or the simulator 200. The psychological state may be the stress (degree of stress) of the operator MP when operating the construction machine 100 or the simulator 200.

[0031] The psychological state improvement command is a command for improving the psychological state of the operator MP when operating the construction machine 100. In other words, the psychological state improvement command is used for improving the psychological state of the operator MP when operating the construction machine 100. Improving the psychological state of the operator MP when operating the construction machine 100 contributes to reducing the burden on the operator MP when operating the construction machine 100. Furthermore, improving the psychological state of the operator MP when operating the construction machine 100 may also contribute to improving the work efficiency of the construction machine 100.

[0032] The content of the psychological state improvement command is not particularly limited as long as it is capable of improving the psychological state of the operator MP when operating the construction machine 100. The content of the psychological state improvement command may be set according to specific circumstances such as the type of target work in which the operator MP is engaged, the type of construction machine 100 operated by the operator MP, and the psychological state of the operator MP. The content of the psychological state improvement command may be, for example, the content of work support as in the first and second aspects described below, the content of improvement control as in the third and fourth aspects described below, or other content.

[0033] The controller 50 inputs the psychological state improvement command to the controlled object. The controlled object performs an operation to improve the psychological state of the operator MP during work using the construction machine 100 based on the psychological state improvement command.

[0034] The control object may be, for example, at least one of the first display 73 and the second display 76 that can be viewed by the operator MP when operating the construction machine 100. The control object may be, for example, an external display 700 that can be viewed by the operator MP, the work manager, an assistant, or other related parties in the work. The control object may be, for example, one included in information devices that can be used by the related parties in the work, such as the work manager. The information device may be, for example, a personal computer, a mobile information terminal, or another information device. The control object may be an alarm device, which will be described later. The control object may be, for example, an audio device 74 or a lighting device 75.

[0035] The controller 50 may be a part of the construction machine 100, may be a part of the simulator 200, or may be a part of a management device 500 such as a server. The controller 50 may be a component separate from the construction machine 100, the simulator 200, and the management device 500. The work support system 300 may include at least one of the construction machine 100, the simulator 200, and the management device 500, or may not include the construction machine 100, the simulator 200, and the management device 500.

[0036] The construction machine 100 (actual machine) is, for example, a crawler excavator, and includes, as shown in Fig. 2, a lower traveling body 1, an upper rotating body 2 rotatably supported on the lower traveling body 1, and a working device 3 supported on the upper rotating body 2. The working device 3 includes a boom 4 supported on the upper rotating body 2 so as to be able to rise and fall, an arm 5 rotatably supported on the boom 4, and a tip attachment 6 rotatably supported on the arm 5. The tip attachment 6 may be a bucket 6A used for excavation work such as excavating an excavation target such as earth and sand, a gripping device 6B used for gripping work such as gripping an object to be gripped, or another tip attachment such as a crusher. The upper rotating body 2 includes a rotating frame rotatably supported on the lower traveling body 1, and a cab 7 supported on the rotating frame.

[0037] The construction machine 100 includes a control device 70 arranged in the cab 7. The control device 70 includes a seat 71 on which the operator MP sits, a controller 72 that receives various operations performed by the operator MP to operate the construction machine 100, and an alarm. The controller 72 includes at least one of an operation lever and an operation pedal. The alarm notifies the operator MP of various information. The alarm may include a first display 73 that displays various information for the operator MP. The first display 73 may be configured to be able to receive an input (operation input) from the operator MP. The first display 73 is arranged in a position that can be visually confirmed by the operator MP when operating the construction machine 100 (for example, a position in front of the seat 71 or a position to the side of the seat 71). The alarm may include at least one of an audio device 74 and a lighting device 75. The audio device 74 notifies the operator MP of various information by sound. The lighting device 75 uses light to notify the pilot MP of various types of information.

[0038] The operation of the construction machine 100 may be performed by the operator MP riding on the construction machine 100 (actual machine) and operating the construction machine 100, or may be performed by the operator MP operating the construction machine 100 (actual machine) using a remote control device arranged at a location remote from the construction machine 100. In this case, the remote control device is another example of the operation device 70. The remote control device may include a second display 76 as the annunciator. The second display 76 may be configured to display, for example, an image of a work site, which is an image taken by a camera mounted on the construction machine 100. The image of the work site may include an image of the work site spreading out in front of the upper rotating body 2. The second display 76 may be configured, for example, as a display such as a liquid crystal display, and may be arranged in front of the seat 71 so that the operator MP seated in the seat 71 can see it. Furthermore, the operation of the construction machine 100 may be the operation when performing work at an actual work site 400, or the operation of the construction machine 100 when practicing work at a training school 600 to improve the operation skills of the construction machine 100.

[0039] The simulator 200 includes a virtual space builder 201 and a control device 70. The control device 70 of the simulator 200 includes a seat 71, a controller 72, and an alarm, similar to the control device 70 of the construction machine 100, and the alarm may include a first display 73 or a second display 76. The virtual space builder 201 may build a three-dimensional work site model 400a (virtual work site) that simulates a work site and a three-dimensional construction machine model 100a (virtual construction machine) that simulates a construction machine in a computer space, and may display an image of the work site model 400a and an image of the construction machine model 100a on, for example, the second display 76. The construction machine model 100a includes a lower traveling body model 1a that simulates the lower traveling body 1, an upper rotating body model 2a that simulates the upper rotating body 2, and a work implement model 3a that simulates the work implement 3. The work implement model 3a includes a boom model 4a that simulates the boom 4, an arm model 5a that simulates the arm 5, and a tip attachment model 6a that simulates the tip attachment 6.

[0040] The image displayed on the second display 76 may be an image from an arbitrary viewpoint in the computer space in which the work site model 400a and the construction machine model 100a are constructed. The arbitrary viewpoint may be a preset viewpoint, a viewpoint selected by the operator MP, or a viewpoint selected by the virtual space builder 201 based on a preset condition. When the viewpoint changes, the position of the image of the work site model 400a and the construction machine model 100a displayed on the second display 76, the direction in which the work site model 400a and the construction machine model 100a are viewed, and the like change. Specifically, for example, the image displayed on the second display 76 may be an image viewed from a predetermined part of the upper rotating body (for example, an image including the work site located in front of the work equipment and the construction machine), or an image captured in a predetermined direction from a predetermined place on the work site (for example, an image including the construction machine and the work site around it). The image displayed on the second display 76 may also include multiple images captured from multiple viewpoints. That is, the image displayed on the second display 76 may simultaneously display the multiple images.

[0041] When the operator MP sitting in the seat 71 operates the controller 72, the simulator 200 changes the image of the construction machine model 100a displayed on the second display 76 in response to the operation, and also changes the image of the work site model 400a as necessary. The simulator 200 also displays on the second display 76 a virtual work content (e.g., virtual excavation work) that imitates work at an actual work site in response to the change in the image of the construction machine model 100a.

[0042] When the simulator 200 is started, for example, the operator MP is made to select a work content via the first display 73, and the operator MP is made to perform the work content using the virtual work site model 400a and the virtual construction machine model 100a, thereby training the operator MP. When the training is completed, the simulator 200 may transmit a simulation result in which the result of the work by the operator MP and the identification information of the operator MP are associated with each other to a management device 500 such as a server. The simulator 200 may also transmit the simulation result to the controller 50. When at least one of the management device 500 and the controller 50 acquires the simulation result, the database may be updated so that the simulation result is stored in the memory. As a result, the history of the simulation performed by the operator MP is accumulated in the database.

[0043] The work support system 300 includes a psychological state acquirer 60. The psychological state acquirer 60 acquires psychological state information that is information that correlates with the psychological state of the operator MP, and outputs the information to the controller 50. The psychological state information may be information that correlates with the impatience of the operator MP when operating the construction machine 100 or the simulator 200. The psychological state information may also be information that correlates with the fatigue of the operator MP when operating the construction machine 100 or the simulator 200. The psychological state information may also be information that correlates with the concentration of the operator MP when operating the construction machine 100 or the simulator 200. The psychological state information may also be information that correlates with the irritation (impatience) of the operator MP when operating the construction machine 100 or the simulator 200. The psychological state information may also be information that correlates with the stress of the operator MP when operating the construction machine 100 or the simulator 200.

[0044] The psychological state acquirer 60 may include a psychological state input acceptor 60A (see FIG. 10) described later that accepts a psychological state input that is an input related to the psychological state of the operator MP. In this case, a person involved in the work, such as the operator MP, may perform the psychological state input to the psychological state input acceptor 60A. The psychological state input acceptor 60A inputs information related to the psychological state input to the controller 50 as the psychological state information. The psychological state acquirer 60 may include a psychological state detector that detects the psychological state information. The psychological state detector may be, for example, a sound collector 60B (see FIG. 11) described later, a biological information sensor 60C (see FIG. 11) described later, or another detector. The psychological state detector inputs the psychological state information to the controller 50.

[0045] FIG. 3 is a flowchart showing an example of a calculation process performed by the controller 50 of the task support system 300.

[0046] The controller 50 acquires psychological state information relating to the psychological state of the pilot MP outputted from the psychological state acquirer 60 (step S1).

[0047] The controller 50 determines the content of the psychological state improvement command using the acquired psychological state information (step S2).

[0048] The controller 50 inputs the determined psychological state improvement command to the control target (step S3).

[0049] The controlled object performs an operation in response to a psychological state improvement command input from the controller 50. This can improve the psychological state of the operator MP during work using the construction machine 100.

[0050] The controller 50 repeatedly performs the processes of steps S1 to S3 during the startup of the system.

[0051] [Configuration common to the first and second aspects] Next, a work support system 300AB having a configuration common to the work support system 300A according to the first embodiment and the work support system 300B according to the second embodiment will be described. Fig. 4 is a block diagram showing the configuration of the work support system 300AB.

[0052] The work support system 300AB shown in Fig. 4 includes a controller 50. The controller 50 includes a quantitative value calculation unit and a support content determination unit. The quantitative value calculation unit and the support content determination unit are each realized by the arithmetic processing device executing a control program stored in the memory in the controller 50. The quantitative value calculation unit and the support content determination unit are an example of a command content determination unit in the work support system 300 shown in Fig. 1.

[0053] The quantitative value calculation unit calculates a psychological state quantitative value that is a value that quantifies the psychological state of the driver MP based on the psychological state information. This psychological state quantitative value may be an impatience quantitative value that is a value that quantifies the degree of impatience of the driver MP, a fatigue quantitative value that is a value that quantifies the fatigue of the driver MP, or a concentration quantitative value that is a value that quantifies the concentration of the driver MP. In the work support system 300AB shown in FIG. 4, the psychological state information is information that correlates with the psychological state of the driver MP when operating the construction machine 100.

[0054] The support content determination unit determines the content of the work support for improving the psychological state of the operator MP when operating the construction machine 100, using the psychological state quantitative value.

[0055] The content of the work support is not particularly limited as long as it is capable of improving the psychological state of the operator MP when operating the construction machine 100. The content of the work support may be set according to specific circumstances such as the type of target work in which the operator MP is engaged, the type of construction machine 100 operated by the operator MP, and the psychological state of the operator MP.

[0056] The content of the work support may include changing the work conditions of the target work to contents capable of improving the psychological state of the pilot MP. The work conditions may be a target workload set as a target for the workload of the pilot MP, and in this case, the content of the work support may be adjusting the target workload of the pilot MP to a value capable of improving the psychological state of the pilot MP. The work conditions may be the number of members of a work team engaged in the target work, and in this case, the content of the work support may include adjusting the number of members of a work team engaged in the target work to a number capable of improving the psychological state of the pilot MP. When the target work includes a plurality of work contents, the work conditions may be which of the plurality of work contents the pilot MP is in charge of, and in this case, the content of the work support may be changing the work content in which the pilot MP is in charge to work content capable of improving the psychological state of the pilot MP. The work conditions may be the deadline for the target work in which the pilot MP is engaged, and in this case, the content of the work support may be changing the deadline for the target work to a deadline capable of improving the psychological state of the pilot MP. When the construction machine 100 operated by the operator MP is selected from among a plurality of construction machines, the work conditions may be the characteristics of the construction machine 100 operated by the operator MP, and in this case, the content of the work support may be changing the construction machine 100 operated by the operator MP to a construction machine having characteristics that can improve the psychological state of the operator MP.

[0057] FIG. 5 is a flowchart showing an example of a calculation process performed by the controller 50 of the task support system 300AB shown in FIG.

[0058] The controller 50 acquires the psychological state information on the psychological state of the pilot MP outputted from the psychological state acquirer 60 (step S11).

[0059] The controller 50 calculates a psychological state quantitative value using the acquired psychological state information (step S12).

[0060] The controller 50 determines the content of the work support using the calculated psychological state quantitative value (step S13).

[0061] The controller 50 inputs a work support command, which is a command corresponding to the determined content of the work support, to the control target (step S14). The work support command is an example of a psychological state improvement command.

[0062] The controlled object performs an operation according to the work support command input from the controller 50, i.e., an operation corresponding to the determined content of the work support. This can improve the psychological state of the operator MP during work using the construction machine 100.

[0063] The controller 50 repeatedly performs the processes of steps S11 to S14 during the system startup.

[0064] [Configuration common to the third and fourth aspects] Next, a work support system 300CD having a configuration common to the work support system 300C according to the third embodiment and the work support system 300D according to the fourth embodiment will be described. Fig. 6 is a block diagram showing the configuration of the work support system 300CD.

[0065] The work support system 300CD shown in Fig. 6 includes a controller 50. The controller 50 includes a time series data acquisition unit, an incidental condition management unit, and a control content determination unit. The time series data acquisition unit, the incidental condition management unit, and the control content determination unit are each realized by the arithmetic processing device executing a control program stored in the memory in the controller 50. The time series data acquisition unit, the incidental condition management unit, and the control content determination unit are an example of a command content determination unit in the work support system 300 shown in Fig. 1.

[0066] The time series data acquisition unit acquires data regarding the psychological state (specifically, for example, psychological state time series data, which is data regarding time-series changes in the psychological state) based on the psychological state information, which is information correlating with the psychological state of the operator MP when operating at least one of the construction machine 100 and the simulator 200.

[0067] The incidental condition management unit transmits or acquires information regarding changes in incidental conditions during at least one of the operation of the construction machine 100 and the operation of the simulator 200. That is, the incidental condition management unit may transmit information regarding changes in the incidental conditions, or may acquire information regarding changes in the incidental conditions.

[0068] Specifically, for example, the incidental condition management unit may transmit change promotion information, which is information for encouraging a change in the psychological state of the operator MP when operating at least one of the construction machine 100 and the simulator 200, as in a third aspect described later. Also, the incidental condition management unit may acquire data on the incidental conditions (specifically, for example, incidental condition time-series data, which is data on time-series changes in the incidental conditions), as in a fourth aspect described later.

[0069] The information regarding the change in the incidental situation may be information regarding a change in the surrounding situation. The information regarding the change in the surrounding situation may be, for example, information regarding a change in the surrounding situation of the construction machine 100, information regarding a change in the surrounding situation of the construction machine model 100a in the virtual space constructed by the simulator 200, or information regarding a change in the surrounding situation of the operator MP. The information regarding the change in the incidental situation may be information regarding a change in the work content performed by the construction machine 100.

[0070] The control content determination unit determines the content of improvement control, which is a control for improving the psychological state of the operator MP when operating the construction machine 100, by using the psychological state time series data and the change in the incidental situation. Specifically, for example, as in a third aspect described later, the control content determination unit may determine the content of improvement information to be transmitted to improve the psychological state of the operator MP when operating the construction machine 100 by using data related to the change in the psychological state before and after the transmission of the change promotion information. Also, as in a fourth aspect described later, the control content determination unit may determine training content for training the operator MP by using the psychological state time series data and the incidental situation time series data described later. The training content is an example of support content for improving the operator MP's proficiency in operating the construction machine.

[0071] The psychological state time series data is data acquired based on the psychological state information, and is data relating to time series changes in the psychological state of the operator MP. The psychological state time series data may be data relating to time series changes in the psychological state of the operator MP when operating the construction machine 100, and in this case, the psychological state information is information correlating with the psychological state of the operator MP when operating the construction machine 100. The psychological state time series data may be data relating to time series changes in the psychological state of the operator MP when operating the simulator 200, and in this case, the psychological state information is information correlating with the psychological state of the operator MP when operating the simulator 200. In addition, the psychological state time series data may include data regarding time series changes in the psychological state of the operator MP when operating the construction machine 100 and data regarding time series changes in the psychological state of the operator MP when operating the simulator 200, and in this case, the psychological state information includes information correlating with the psychological state of the operator MP when operating the construction machine 100 and information correlating with the psychological state of the operator MP when operating the simulator 200.

[0072] The controller 50 can acquire the psychological state time-series data by continuously or periodically receiving the psychological state information from the psychological state acquirer 60 over time. The psychological state time-series data may be the time-series data of the psychological state information continuously or periodically input to the controller 50. The psychological state time-series data may be the time-series data of the psychological state information continuously or periodically input to the controller 50, which has been processed by the controller 50.

[0073] The content of the improvement control is not particularly limited as long as it is content that can improve the psychological state of the operator MP when operating the construction machine 100. The content of the improvement control may be set according to specific circumstances such as the type of the target work, the type of construction machine 100 operated by the operator MP, and the psychological state of the operator MP. The content of the improvement control may be, for example, transmitting improvement information to improve the psychological state of the operator MP when operating the construction machine 100. Furthermore, the content of the improvement control may be training content for training the operator MP to improve the psychological state of the operator MP when operating the construction machine 100.

[0074] FIG. 7 is a flowchart showing an example of a calculation process performed by the controller 50 of the task support system 300CD shown in FIG.

[0075] The controller 50 sequentially acquires, in time series, the psychological state information related to the psychological state of the operator MP input from the psychological state acquirer 60 while operating the construction machine 100 or the simulator 200. In parallel with acquiring the psychological state information in time series, the controller 50 transmits or acquires information related to changes in attendant circumstances. The controller 50 associates and stores these pieces of information to acquire (generate) the psychological state time series data, which is data related to the time series changes in the psychological state (step S21).

[0076] The controller 50 determines the content of the improvement control using the acquired psychological state time series data and information on the change in the attendant situation (step S22). Specifically, for example, the controller 50 may determine the content of the improvement control using the psychological state time series data and information on the timing of the change in the attendant situation.

[0077] The controller 50 inputs an improvement control command, which is a command corresponding to the determined content of the improvement control, to the control target (step S23). The improvement control command is an example of the psychological state improvement command.

[0078] The controlled object performs an operation according to the improved control command input from the controller 50, i.e., an operation corresponding to the determined content of the improved control. This can improve the psychological state of the operator MP during work using the construction machine 100.

[0079] The controller 50 repeatedly performs the processes of steps S21 to S23 during the system startup.

[0080] As described above, in the work support system 300CD, the data on the psychological state is psychological state time series data on the time series change of the psychological state, the data on the incidental situation is incidental situation time series data on the time series change of the incidental situation, and the controller 50 uses the psychological state time series data and the incidental situation time series data to determine the training content for training the pilot MP as the support content. However, in the work support system 300CD having a configuration common to the third and fourth aspects, the support content is not limited to the training content, and may be other support content for improving the pilot MP's proficiency in maneuvering. In the work support system 300CD having a configuration common to the third and fourth aspects, the data on the psychological state does not necessarily have to be the time series data, and the data on the incidental situation does not necessarily have to be the incidental situation time series data.

[0081] [First aspect] FIG. 8 is a block diagram showing a task support system 300A according to the first embodiment.

[0082] The work support system 300A shown in Fig. 8 includes a controller 50. The controller 50 includes a quantitative value calculation unit, a target psychological state setting unit, and a support content determination unit. The quantitative value calculation unit, the target psychological state setting unit, and the support content determination unit are each realized by the arithmetic processing device executing a control program stored in the memory in the controller 50. The quantitative value calculation unit, the target psychological state setting unit, and the support content determination unit are one example of a command content determination unit in the work support system 300 shown in Fig. 1.

[0083] The quantitative value calculation unit calculates a psychological state quantitative value, which is a value that quantifies the psychological state of the pilot MP based on the psychological state information.

[0084] The target psychological state setting unit sets a target psychological state which is a target psychological state when operating the construction machine 100 .

[0085] The support content determination unit uses the psychological state quantitative value and the target psychological state to determine the content of work support for improving the psychological state of the operator MP when operating the construction machine 100.

[0086] In the work support system 300A shown in Fig. 8, the psychological state information is information that correlates with the psychological state of the operator MP when operating the construction machine 100. The target psychological state may be, for example, a specific target (e.g., a target value) that is preset in the controller 50, or may be a target (e.g., a target value) that is set by the controller 50 using information for setting the target psychological state (target setting information).

[0087] FIG. 9 is a flowchart showing an example of a calculation process performed by the controller 50 of the work support system 300A according to the first embodiment.

[0088] The controller 50 acquires the psychological state information on the psychological state of the pilot MP outputted from the psychological state acquirer 60 (step S31).

[0089] The controller 50 calculates a psychological state quantitative value using the acquired psychological state information (step S32).

[0090] The controller 50 sets a target psychological state which is a target psychological state when operating the construction machine 100 (step S33).

[0091] The controller 50 determines the content of the work support using the calculated psychological state quantitative value and the set target psychological state (step S34). Specifically, for example, the controller 50 may determine the content of the work support using a difference between a target value as the target psychological state and the psychological state quantitative value.

[0092] The controller 50 inputs a work support command, which is a command corresponding to the determined content of the work support, to the control target (step S35). The work support command is an example of the psychological state improvement command.

[0093] The controlled object performs an operation according to the work support command input from the controller 50, i.e., an operation corresponding to the determined content of the work support. This can improve the psychological state of the operator MP during work using the construction machine 100.

[0094] The controller 50 presents the content of the work support to the work manager (step S36). The content of the work support presented to the work manager may be at least one of the content of the work support executed by the controller 50 and the content of the work support to be executed by the work manager.

[0095] The controller 50 repeatedly performs the processes of steps S31 to S36 during the system startup.

[0096] Next, a modified example of the first embodiment will be described. Figures 10 to 22 are diagrams for explaining a task support system 300A according to a modified example of the first embodiment.

[0097] In the work support system 300A relating to a modified example of the first aspect, the psychological state of the operator MP acquired by the controller 50 from the psychological state acquirer 60 is the operator MP's impatience (degree of impatience) when operating the construction machine 100, the psychological state quantitative value calculated by the quantitative value calculation unit of the controller 50 is an impatience quantitative value that is a value that quantifies the degree of the operator MP's impatience, and the target psychological state set by the target psychological state setting unit of the controller 50 is a target impatience value that is a target for the degree of the operator MP's impatience.

[0098] The psychological state acquirer 60 may include a psychological state input receiver 60A (see FIG. 10) that allows a worker involved in the work, such as a driver MP, to input psychological state information that is information correlated with the psychological state of the driver MP. The psychological state input receiver 60A outputs the input psychological state information to the controller 50.

[0099] Specifically, for example, the psychological state input receiver 60A may include a screen 601 that displays at least one question (for example, a questionnaire) for the person involved in the work (for example, the operator MP), and an input unit 602 in which the person involved in the work inputs an answer to the at least one question. The at least one question includes a content that can evaluate the psychological state of the operator MP when operating the construction machine 100, specifically, a content that can evaluate the degree of impatience of the operator MP when operating the construction machine 100. Therefore, the psychological state information input from the psychological state input receiver 60A to the controller 50 becomes an index for evaluating the degree of impatience of the operator MP when operating the construction machine 100. The question may be, for example, "Are you paying attention to the work?", "Is the work difficult?", "Is the pace of the work fast?", or other content.

[0100] The operator MP may input an answer to the at least one question into the psychological state input receiver 60A after operating the construction machine 100 or during a break between operating the construction machine 100. The answer by the operator MP may be, for example, a numerical value indicating the degree of impatience. The psychological state input receiver 60A may be installed in the cab 7 of the construction machine 100, may be a portable information terminal that can be brought into the cab 7 of the construction machine 100 and taken out of the cab 7, or may be another information device.

[0101] The psychological state acquirer 60 may include a sound collector 60B such as a microphone capable of collecting the voice of the operator MP (see FIG. 11). The sound collector 60B outputs audio information related to the collected voice to the controller 50. The operator MP may utter words according to his / her psychological state while operating the construction machine 100. Specifically, as shown in the graph of FIG. 11, for example, the operator MP tends to utter negative words more frequently (amount of negative words uttered) as the degree of impatience increases while operating the construction machine 100. Therefore, the audio information collected by the sound collector 60B and output to the controller 50 serves as an index for evaluating the degree of impatience of the operator MP while operating the construction machine 100.

[0102] The psychological state acquisition device 60 may include a bioinformation sensor 60C capable of detecting changes in bioinformation (see FIG. 11). The bioinformation sensor 60C outputs the detected bioinformation to the controller 50. The bioinformation may be, for example, the balance between the sympathetic nerves (LF) and the parasympathetic nerves (HF), that is, the autonomic nerve balance (LF / HF). For example, as shown in the graph of FIG. 12, the value of the autonomic nerve balance (LF / HF) of the operator MP tends to increase as the degree of stress, such as impatience, increases. The bioinformation may be, for example, the blood pressure of the operator MP, the heart rate of the operator MP, the amount of sweat of the operator MP, or other bioinformation of the operator MP. The blood pressure, heart rate, and amount of sweat of the operator MP tend to increase as the degree of stress, such as impatience, increases. Therefore, the bioinformation detected by the bioinformation sensor 60C and output to the controller 50 is an index for evaluating the degree of impatience of the operator MP when operating the construction machine 100.

[0103] The quantitative value calculation unit of the controller 50 calculates an impatience quantitative value that quantifies the psychological state of the operator MP based on the psychological state information of the operator MP input from the psychological state acquirer 60 when operating the construction machine 100. This impatience quantitative value is an example of the psychological state quantitative value.

[0104] When the psychological state acquirer 60 includes the psychological state input acceptor 60A, the quantitative value calculation section of the controller 50 may calculate the impatience quantitative value using the psychological state information input from the psychological state input acceptor 60A to the controller 50. When each of the multiple answers input to the psychological state input acceptor 60A is a numerical value, the impatience quantitative value may be, for example, a total value of multiple numerical values ​​corresponding to the multiple answers included in the psychological state information, or an average value of multiple numerical values ​​corresponding to the multiple answers.

[0105] In a case where the psychological state acquirer 60 includes a sound collector 60B, the quantitative value calculation unit of the controller 50 may calculate the quantitative value of impatience using the amount of negative words contained in the audio information and a pre-set map such as the graph in Figure 11.

[0106] In a case where the psychological state acquirer 60 includes a bio-information sensor 60C, the quantitative value calculation unit of the controller 50 may calculate the impatience quantitative value using the bio-information (e.g., autonomic nerve balance (LF / HF)) and a pre-set map such as the graph in FIG. 12.

[0107] The controller 50 (target psychological state setting unit) sets a target impatience value, which is a target psychological state when operating the construction machine 100. This target impatience value is an example of the target psychological state. The target impatience value may be set in advance and stored in the controller 50, for example. The target impatience value may be set in advance for each operator MP and stored in the controller 50, for example. The controller 50 may also set the target impatience value based on a target input entered into a specified input device by a person involved in the work, such as the operator MP or a work manager. In this case, the target input is an example of the target setting information.

[0108] Furthermore, the controller 50 (target psychological state setting unit) may set the target impatience value using a target characteristic that is a characteristic that represents the target impatience value as a function of the work situation. In this case, the target characteristic is an example of the target setting information. The controller 50 can obtain information on the actual work situation and determine the target impatience value using the obtained work situation and the target characteristic.

[0109] The work situation may be a work situation that affects the psychological state of the operator MP. The work situation may be, for example, the progress of the work. In this case, the controller 50 may set the impatience target value using, for example, a target characteristic that is a characteristic that expresses the impatience target value as a function of the progress of the work. Specifically, as shown in FIG. 13, for example, the controller 50 may set the impatience target value using an impatience target characteristic Isp as the target characteristic. The impatience target characteristic Isp shown in FIG. 13 is a characteristic that expresses the relationship between the progress of the work and the impatience target value.

[0110] In Fig. 13, the horizontal axis of the graph represents the progress of the work, and the vertical axis of the graph represents the degree of impatience (quantitative impatience value and target impatience value). In Fig. 13, the origin of the graph indicates that the progress of the work is according to plan, the right side of the origin on the horizontal axis of the graph indicates that the actual progress of the work is behind the plan, and the left side of the origin on the horizontal axis of the graph indicates that the actual work is ahead of the plan. The horizontal axis of the graph is the progress difference (planned - actual progress), and the larger this progress difference, the greater the degree of delay against the plan.

[0111] The impatience target characteristic Isp shown in FIG. 13 is set so that the impatience target value increases as the degree of delay in the work increases. This makes it possible to encourage the pilot MP to become more impatient as the degree of delay in the work increases, and as a result, makes it possible to reduce delays in the work. Furthermore, the impatience target characteristic Isp shown in FIG. 13 is set so that when the actual work is progressing more than planned (when the actual progress exceeds the plan), the impatience target value decreases as the amount of excess increases. When there are multiple pilots MP, the impatience target characteristic Isp may be set individually for each of the multiple pilots MP.

[0112] The controller 50 (target psychological state setting unit) may set the impatience target characteristic Isp suitable for each of the multiple operators MP, for example, as follows. At least one of the management device 500 and the controller 50 may include a database that stores data on tasks performed in the past by each of the multiple operators MP, for example, as shown in FIG. 14. In the database, the contents of multiple tasks (multiple task contents) performed in the past by each of the multiple operators MP, the progress difference in each of the multiple task contents, the degree of impatience, and the identification information of the operator MP are stored in association with each other. FIG. 15 is an example of a graph plotting data for one of the multiple operators MP stored in the database. The horizontal axis of the graph shown in FIG. 15 represents the progress of the task (progress difference), and the vertical axis of the graph represents the degree of impatience. In the database, data as shown in FIG. 15 is stored for each of the multiple operators MP.

[0113] The controller 50 (target psychological state setting unit) may use data such as that shown in Fig. 15, which indicates the relationship between the progress difference and the degree of impatience for each pilot MP, to set the function shown by the solid approximation curve in Fig. 15 as the impatience target characteristic Isp. This impatience target characteristic Isp may be a function set using a method such as the least squares method.

[0114] The controller 50 (target psychological state setting unit) may set the impatience target characteristic Isp, for example, as follows: Fig. 16 is a graph showing an example of the relationship between the quantitative value of impatience (horizontal axis x) of the operator MP when operating the construction machine 100 and work efficiency such as productivity (vertical axis y). Fig. 17 is a graph showing an example of the relationship between the quantitative value of impatience (horizontal axis x) of the operator MP when operating the construction machine 100 and the degree of comfort of the operator MP (vertical axis y). The degree of comfort of the operator MP can be rephrased as, for example, a sense of security or a sense of satisfaction.

[0115] As shown in FIG. 16, the relationship between the degree of impatience and productivity can be expressed, for example, by a function f(x) having an inverted U shape. That is, as shown in the function f(x) in FIG. 16, when the pilot MP is moderately impatient, the work efficiency (productivity) is highest, and when the degree of impatience is excessively high or excessively low, the work efficiency (productivity) tends to decrease. As shown in FIG. 17, the relationship between the degree of impatience and the degree of good mood can be expressed, for example, by a function g(x). As shown in the function g(x) in FIG. 17, the degree of good mood of the pilot MP tends to decrease as the degree of impatience increases.

[0116] The controller 50 (target psychological state setting unit) may set the impatience target value using a function f(x) and a function g(x). In this case, information including the function f(x) and the function g(x) is an example of the target setting information.

[0117] Specifically, for example, the controller 50 may set the sum (P) of a function f(x) and a function g(x) as the evaluation function, as shown in the following equation (1), and determine the target impatience value I (target psychological state) that maximizes the sum (P).

[0118] P = max(f(x) + g(x)) (1)

[0119] In this case, the controller 50 can determine the impatience target value I that appropriately balances the efficiency of work (productivity) and the good mood of the pilot MP, as shown in Fig. 18. As shown in Fig. 18, the determined impatience target value I can appropriately balance the efficiency of work (productivity) and the good mood of the pilot MP, compared to the degree of impatience in state 1 and the degree of impatience in state 2.

[0120] If there is a function h(x) to be taken into consideration when determining the impatience target value I, other than the function f(x) relating to productivity and the function g(x) relating to the good mood, the controller 50 may set the sum (P) of the functions f(x), g(x), and h(x) as the evaluation function, as shown in the following equation (2), and determine the impatience target value I (target psychological state) that maximizes the sum (P).

[0121] P=max(f(x)+g(x)+h(x)) ···(2)

[0122] The controller 50 may set an evaluation function in which the functions f(x) and g(x) are weighted as shown in the following equation (3), and determine the target impatience value I (target psychological state) that maximizes the sum (P) of the evaluation functions.

[0123] P=max(w×f(x)+(1-w)×g(x)) ···(3)

[0124] The coefficient w in formula (3) may be determined taking into consideration which of the efficiency (productivity) of the work and the good mood of the pilot MP is to be prioritized. The coefficient w may be, for example, a value correlated with the number of days remaining until the deadline of the work. When the number of days remaining is greater than a reference value, the good mood of the pilot MP is prioritized over the efficiency (productivity) of the work, and the coefficient w may be set to a relatively small value. On the other hand, when the number of days remaining is equal to or less than the reference value, the efficiency (productivity) of the work is prioritized over the good mood of the pilot MP, and the coefficient w may be set to a relatively large value.

[0125] The database may store a function f(x) and a function g(x) common to each pilot MP. The database may store a function f(x) and a function g(x) prepared for each of a plurality of pilot MPs. The database may store a plurality of preset function sets. The plurality of function sets correspond to a plurality of preset levels of work skill, respectively. Each function set includes a function f(x) and a function g(x). Specifically, as shown in FIG. 19, the database may store a function f(x) and a function g(x) set for a pilot MP with a high work skill level, a function f(x) and a function g(x) set for a pilot MP with a medium work skill level, and a function f(x) and a function g(x) set for a pilot MP with a low work skill level.

[0126] The controller 50 (support content determination unit) determines the content of the work support for improving the psychological state of the operator MP when operating the construction machine 100, using the impatience quantitative value as a psychological state quantitative value and the impatience target value as a target psychological state. Specifically, for example, the controller 50 may determine the content of the work support using an impatience difference (impatience target value-impatience quantitative value), which is the difference between the impatience target value and the impatience quantitative value. In other words, the controller 50 may determine the content of the work support required to bring the impatience quantitative value closer to the impatience target value, using the impatience difference.

[0127] The controller 50 may present the determined content of the work support to a work manager who manages the work site. This allows the work manager to execute work support to improve work efficiency (productivity), execute work support to increase the degree of comfort of the pilot MP, or execute work support to moderately increase both the work efficiency (productivity) and the degree of comfort. The work support may be executed by the controller 50 instead of by the work manager. In this case, the controller 50 may both present the determined content of the work support to the work manager and execute the work support, or execute the work support without presenting the determined content of the work support to the work manager.

[0128] The work support may be, for example, the following specific examples. The work support may be adjusting the amount of work for which the pilot MP is responsible, i.e., increasing or decreasing the amount of work. The work support may be adjusting the number of people in a work team including the pilot MP, i.e., increasing or decreasing the number of people. The work support may be adjusting the delivery date for the work for which the pilot MP is responsible, i.e., extending or shortening the delivery date.

[0129] The content of the work support is preferably to change the work conditions of the pilot MP to change the level of the work burden of the pilot MP, as shown in the flowchart in Fig. 22 described later. Specifically, when the pilot MP's psychological state is relaxed with respect to the target impatience (e.g., the impatience target value), i.e., when the pilot MP is not in a hurry, the content of the work support is preferably to change the work conditions of the pilot MP so that the work burden of the pilot MP increases. On the other hand, when the pilot MP's psychological state is not relaxed with respect to the target impatience (e.g., the impatience target value), i.e., when the pilot MP is in a hurry, the content of the work support is preferably to change the work conditions of the pilot MP so that the work burden of the pilot MP decreases.

[0130] 20 is a flowchart showing an example of a calculation process performed by the controller 50. In step S101, the controller 50 acquires progress status information, which is information related to the progress status of the work. Specifically, for example, the operator MP, the work manager, or other related parties in the work input the progress status into a predetermined input device for inputting the progress status, whereby the controller 50 can acquire the progress status information.

[0131] In step S102, the controller 50 calculates the quantitative impatience value x using any of the various methods described above.

[0132] In step S103, the controller 50 calculates the impatience target value I by using the impatience target characteristic Isp and the progress status information shown in, for example, Fig. 13 or Fig. 15. That is, when the progress difference is determined, the controller 50 can calculate the impatience target value I by using a function corresponding to the impatience target characteristic Isp shown in Fig. 13 or Fig. 15.

[0133] In step S104, the controller 50 calculates an impatience difference e which is the difference between the impatience target value I and the impatience quantitative value x, that is, a value obtained by subtracting the impatience quantitative value x from the impatience target value I (impatience target value I−impatience quantitative value x).

[0134] In step S105, the controller 50 determines whether the impatience difference e is smaller than a preset first threshold value Th1. If the impatience difference e is smaller than the first threshold value Th1 (YES in step S105), the controller 50 suspends the execution of work support. This is because, when the impatience difference e is smaller than the first threshold value Th1, the actual degree of impatience of the operator MP when operating the construction machine 100 is close to the target degree of impatience, and work support for the operator MP is not necessary.

[0135] On the other hand, if the impatience difference e is equal to or greater than the first threshold value Th1 (NO in step S105), in step S106, the controller 50 controls the control object to notify the work manager that work support for the pilot MP is necessary. Specifically, the controller 50 transmits work support information, which is information related to work support, to an external display 700 that can be visually confirmed by the work manager, via a communication device, and causes the external display 700 to display the work support information. In this case, the external display 700 is an example of the control object. The communication device may be included in the work support system 300, or may be prepared separately from the work support system 300. The communication between the communication device and the external display 700 may be wireless communication or wired communication. The work support information may include information related to the necessity of work support for the pilot MP, or may include information related to the content of the work support. The content of the work support may be a specific work support preset in the controller 50, or may be any work support selected by the controller 50 from a plurality of options stored in the controller 50 according to the magnitude of the impatience difference e. The work manager can recognize that the operator MP needs work support by receiving the content of the work support from the controller 50, and can recognize the appropriate content of the work support for the operator MP. Then, the work manager can execute the work support for the operator MP at an appropriate timing.

[0136] Instead of the work manager executing the work support, the controller 50 may execute the work support. In this case, the controller 50 may execute a specific work support set in advance, or may execute any work support selected from a plurality of options according to the magnitude of the impatience difference e. The content of the work support may be adjusting the amount of work performed by the pilot MP (increasing or decreasing the amount of work), adjusting the number of members of the work team including the pilot MP (increasing or decreasing the number of members of the work team), or adjusting the delivery date of the work performed by the pilot MP (extending or shortening the delivery date).

[0137] FIG. 21 is a flowchart showing another example of the calculation process performed by the controller 50. In step S111, the controller 50 acquires work skill information, which is information related to the work skill of the operator MP. This work skill information may be included in data related to past work stored in the database, for example, as shown in FIG. 14. Furthermore, the work skill information may be acquired in real time when the operator MP is actually operating the construction machine 100. Furthermore, the work skill of the operator MP may be evaluated based on at least one of the fuel consumption and the work time when operating the construction machine 100, for example.

[0138] In step S112, the controller 50 selects a function set corresponding to the level of the operator MP's work skill from the plurality of function sets stored in the database, and sets the function set as the function set for the operator MP. The function set includes a function f(x) and a function g(x).

[0139] In step S113, the controller 50 uses equation (1), equation (2), or equation (3) to determine the impatience target value I that maximizes the sum (P), that is, the impatience target value I that can adequately balance work efficiency (productivity) and the comfort level of the pilot MP.

[0140] In step S114, the controller 50 calculates an impatience quantitative value (psychological state quantitative value) that quantifies the actual degree of impatience of the pilot MP at that time.

[0141] In step S115, the controller 50 calculates an impatience difference e (impatience target value I-impatience quantitative value x), which is the difference between the impatience target value I and the impatience quantitative value x.

[0142] In step S116, the controller 50 judges whether the impatience difference e is smaller than a preset first threshold value Th1. If the impatience difference e is smaller than the first threshold value Th1 (YES in step S116), the controller 50 suspends the execution of work support. On the other hand, if the impatience difference e is equal to or larger than the first threshold value Th1 (NO in step S116), in step S117, the controller 50 performs control to notify the work manager that work support for the pilot MP is necessary. Specifically, the controller 50 transmits work support information, which is information related to work support, to the external display 700 via the communication device, and causes the external display 700 to display the work support information.

[0143] Fig. 22 is a flowchart showing yet another example of the calculation process performed by the controller 50. The flowchart in Fig. 22 may be performed, for example, after step S105 in Fig. 20, or after step S116 in Fig. 21. That is, when the impatience difference e is equal to or greater than the first threshold value Th1 (NO in step S105 in Fig. 20, or NO in step S116 in Fig. 21), the controller 50 executes the process of step S121 in Fig. 22.

[0144] In step S121, the controller 50 determines whether or not the absolute value of the impatience difference e is smaller than a preset second threshold value Th2. The second threshold value Th2 is a value larger than the first threshold value Th1.

[0145] If the absolute value of the impatience difference e is smaller than the second threshold value Th2 (YES in step S121), in step S122, the controller 50 determines whether or not the impatience difference e is a positive value. On the other hand, if the absolute value of the impatience difference e is equal to or greater than the second threshold value Th2 (NO in step S121), in step S123, the controller 50 determines whether or not the impatience difference e is a positive value. Note that in steps S124 to S127 described below, the contribution of work support due to adjustment of the workload is assumed to be smaller than the contribution of work support due to adjustment of the number of people in the work team.

[0146] If the absolute value of the impatience difference e is smaller than the second threshold value Th2 and the impatience difference e is a positive value (YES in step S121, YES in step S122), the controller 50 performs the process of step S124. In this case, the controller 50 determines that the content of the work support is to increase the target workload (target workload) of the pilot MP (step S124). In this case, the controller 50 may determine the increase in the target workload according to the magnitude of the absolute value of the impatience difference e. Specifically, the controller 50 may increase the target workload such that the increase in the target workload is greater when the absolute value of the impatience difference e is large compared to when the absolute value of the impatience difference e is small.

[0147] If the absolute value of the impatience difference e is smaller than the second threshold value Th2 and the impatience difference e is not a positive value (YES in step S121, NO in step S122), the controller 50 performs the process of step S125. In this case, the controller 50 determines that the content of the work support is to reduce the target workload (target workload) of the pilot MP (step S125). In this case, the controller 50 may determine the amount of reduction in the target workload according to the magnitude of the absolute value of the impatience difference e. Specifically, the controller 50 may reduce the target workload such that the amount of reduction in the target workload is greater when the absolute value of the impatience difference e is large compared to when the absolute value of the impatience difference e is small.

[0148] If the absolute value of the impatience difference e is equal to or greater than the second threshold value Th2 and the impatience difference e is a positive value (NO in step S121, YES in step S123), the controller 50 performs the process of step S126. In this case, the controller 50 determines that the work support content is to reduce the number of people in the work team including the pilot MP (step S126). In this case, the controller 50 may determine the amount of reduction in the number of people depending on the magnitude of the absolute value of the impatience difference e. Specifically, the controller 50 may reduce the number of people such that the amount of reduction in the number of people is greater when the absolute value of the impatience difference e is large compared to when the absolute value of the impatience difference e is small.

[0149] If the absolute value of the impatience difference e is equal to or greater than the second threshold value Th2 and the impatience difference e is not a positive value (NO in step S121, NO in step S122), the controller 50 performs the process of step S127. In this case, the controller 50 determines that the work support content is to increase the number of people in the work team including the pilot MP (step S127). In this case, the controller 50 may determine the increase in the number of people according to the magnitude of the absolute value of the impatience difference e. Specifically, the controller 50 may increase the number of people such that the increase in the number of people is greater when the absolute value of the impatience difference e is large compared to when the absolute value of the impatience difference e is small.

[0150] In step S128, the controller 50 may perform control for presenting the determined content of the work support to the work manager. Specifically, the controller 50 may transmit the determined content of the work support to the external display 700 via a communication device, and cause the external display 700 to display the content of the work support.

[0151] In addition, in Figure 22, adjustment of the workload and adjustment of the number of people in the work team are exemplified as the content of the work support, but the content of the work support may also include extension or shortening of the delivery date of the target work, may include changing the characteristics of the construction machine 100 operated by the operator MP, or may include other content.

[0152] [Second aspect] FIG. 23 is a block diagram showing a task support system 300B according to the second embodiment.

[0153] The work support system 300B shown in FIG. 23 includes a controller 50. The controller 50 includes a quantitative value calculation unit, a productivity acquisition unit, a work content acquisition unit, and a support content determination unit. The quantitative value calculation unit, the productivity acquisition unit, the work content acquisition unit, and the support content determination unit are each realized by the arithmetic processing device executing a control program stored in the memory in the controller 50. The quantitative value calculation unit, the productivity acquisition unit, the work content acquisition unit, and the support content determination unit are an example of a command content determination unit in the work support system 300 shown in FIG.

[0154] The quantitative value calculation unit calculates a psychological state quantitative value, which is a value that quantifies the psychological state of the pilot MP based on the psychological state information.

[0155] The productivity acquisition unit acquires information relating to the productivity of work when the construction machine 100 is operated (productivity information).

[0156] The work content acquisition unit acquires information relating to the work content performed by the construction machine 100 (work content information).

[0157] The support content determination unit uses the psychological state quantitative value and the productivity to determine the content of work support for improving the psychological state of the operator MP when operating the construction machine 100.

[0158] In the work support system 300B, the psychological state information may be information that correlates with the psychological state of the operator MP when operating the construction machine 100.

[0159] FIG. 24 is a flowchart showing an example of a calculation process performed by the controller 50 of the work support system 300B according to the second embodiment.

[0160] The controller 50 acquires the psychological state information on the psychological state of the pilot MP outputted from the psychological state acquirer 60 (step S41).

[0161] The controller 50 calculates a psychological state quantitative value using the acquired psychological state information (step S42).

[0162] The controller 50 calculates the work productivity when operating the construction machine 100 (step S43).

[0163] The controller 50 acquires the details of the work performed by the construction machine 100 (step S44).

[0164] The controller 50 determines the content of the work support using the calculated psychological state quantitative value, the calculated productivity, and the acquired work content (step S45).

[0165] The controller 50 inputs a work support command, which is a command corresponding to the determined content of the work support, to the control target (step S46). The work support command is an example of the psychological state improvement command.

[0166] The controlled object performs an operation according to the work support command input from the controller 50, i.e., an operation corresponding to the determined content of the work support. This can improve the psychological state of the operator MP during work using the construction machine 100.

[0167] The controller 50 presents the content of the work support to the work manager (step S47). The content of the work support presented to the work manager may be at least one of the content of the work support executed by the controller 50 and the content of the work support to be executed by the work manager.

[0168] The controller 50 repeatedly performs the processes of steps S41 to S47 during the system startup.

[0169] Next, a modified example of the second aspect will be described. In a work support system 300B according to the following modified example, the psychological state of the operator MP acquired by the controller 50 from the psychological state acquisition device 60 is the operator MP's impatience (degree of impatience) when operating the construction machine 100, and the psychological state quantitative value calculated by the quantitative value calculation unit of the controller 50 is a value (impatience quantitative value) that quantifies the degree of impatience of the operator MP. In the work support system 300B according to this modified example, the quantitative value calculation unit calculates an impatience quantitative value as the psychological state quantitative value, the productivity acquisition unit acquires the productivity of the work when operating the construction machine 100, the work content acquisition unit acquires the work content by the construction machine 100, and the support content determination unit determines the content of the work support using the impatience quantitative value and the productivity.

[0170] Fig. 25 is a diagram showing a work support system 300B according to a modified example of the second embodiment. In the work support system 300B shown in Fig. 25, the controller 50 can acquire the psychological state (degree of impatience) of the operator MP from the psychological state acquirer 60, as in the first embodiment. The psychological state acquirer 60 may be a psychological state input receiver 60A, a sound collector 60B, a biological information sensor 60C, or another psychological state acquirer, as in the first embodiment.

[0171] The controller 50 (the quantitative value calculation unit) calculates an impatience quantitative value (psychological state quantitative value) based on the psychological state (degree of impatience) of the pilot MP acquired from the psychological state acquisition device 60. The impatience quantitative value may be, for example, one of a plurality of levels as shown in FIG. 26, which will be described later.

[0172] The controller 50 (the work content acquisition unit) may determine the work content based on, for example, an operation (operation input) received by the controller 72 of the control device 70. Examples of the work content include excavation work, lifting and turning work, soil dumping work, and leveling work, but the work content is not limited to these specific examples. The excavation work is a work of excavating the ground using the bucket 6A of the working device 3. The lifting and turning work is a work of moving the bucket 6A holding the excavated soil to directly above a destination such as a truck bed. The soil dumping work is a work of dumping soil from the bucket 6A at the destination. The leveling work is a work of leveling the ground using the bucket 6A. In each of these multiple work contents, the operator MP gives a unique operation to the controller 72 of the control device 70, so that the controller 50 can determine the work content based on the operation (operation input) received by the controller 72 of the control device 70. The information on the operation input is an example of the work content information.

[0173] The controller 50 may also determine the work content based on the operation data of the construction machine 100. In addition, when a person involved in the work, such as the operator MP or the work manager, inputs to a predetermined input device to specify the work content, the controller 50 may determine the work content based on the input. The operation data may include information on the operation of the construction machine 100 accompanying the controller 72 receiving an operation performed by the operator MP. For example, the operation data may include information on the rotation operation of the upper rotating body 2 relative to the lower traveling body 1, or may include information on the operation of the work device 3. Specifically, the operation data may include information on at least one operation of the boom 4, the arm 5, and the tip attachment 6, or may include information on the extension and retraction operation of at least one of a plurality of cylinders that drive the boom 4, the arm 5, and the tip attachment 6. The operation data may include an image of the work site captured by a camera mounted on the construction machine 100 and photographing the work site, and / or a camera installed at the work site and photographing the work site so as to include the construction machine 100. The controller 50 may analyze the image of the work site to determine the work content. Each of the operation data and the input is an example of the work content information.

[0174] The controller 50 (the productivity acquisition unit) may, for example, calculate the amount of work per unit time using information on the actual amount of work and information on the work time required for that work. The amount of work per unit time is an example of work productivity. This allows the controller 50 to acquire the productivity of the work. The information on the actual amount of work and the information on the work time are examples of the productivity information. The controller 50 may also calculate the productivity of the work based on, for example, the progress of the work. The information on the progress of the work is an example of the productivity information.

[0175] The controller 50 can acquire the amount of work for the work, for example, as follows. When the work is an excavation work, the amount of work may be the amount of excavated soil. When the construction machine 100 is equipped with a measuring device capable of measuring the amount of soil, the controller 50 can determine the amount of soil (amount of work) based on data input from the measuring device. When a measuring device capable of measuring the amount of soil is provided at a destination such as the bed of a truck, the controller 50 can determine the amount of soil (amount of work) based on data input from the measuring device. The amount of work may also be a value input into a specified input device by a person involved in the work, such as the operator MP or a work manager.

[0176] The controller 50 can acquire the progress status of the work, for example, as follows: When a person involved in the work, such as the operator MP or the work manager, inputs progress status data relating to the progress status of the work into a predetermined input device, the controller 50 can acquire the progress status of the work based on the progress status data.

[0177] The data on the quantitative value of impatience (quantitative value of psychological state), the productivity of the work, and the work content may be stored in a storage device such as the database.

[0178] The support content determination unit of the controller 50 may determine the content of the work support using the quantitative impatience value and the productivity, for example, as follows.

[0179] FIG. 26 is a diagram showing an example of a map that associates various work support contents with the degree of impatience and productivity. This map may be preset and stored in the database. Also, this map may be generated by the controller 50 based on data related to the quantitative impatience value, work productivity, and work contents stored in the database. The database may store a map as shown in FIG. 26 for each of a plurality of work contents preset. That is, a map suitable for each of a plurality of work contents may be preset.

[0180] In the map shown in Fig. 26, a plurality of levels are set for the degree of impatience of the pilot MP. Specifically, the degree of impatience is quantified into five levels, from level 1, which is the lowest degree of impatience, to level 5, which is the highest degree of impatience. In addition, in the map shown in Fig. 26, a plurality of levels are set for productivity. Specifically, the productivity is quantified into five levels, from level 1, which is the lowest degree of productivity, to level 5, which is the highest degree of productivity.

[0181] In the map shown in FIG. 26, the content of work support is preset for each of 25 combinations obtained from five levels of the degree of impatience and five levels of productivity. In the specific example shown in FIG. 26, the content of work support includes six contents: "no work support", "advice", "low level work support", "medium level work support", "review of workload", and "stop work". "Stop work" is the content with the highest level of support (support level 5: highest support level) and is work support for stopping the work being performed by the pilot MP, and is written as "stop work" in FIG. 26. "Review of workload" is the content with the second highest level of support after "stop work" (support level 4), and is work support for reducing the target workload of the work that the pilot MP is in charge of, for example, and is written as "review of workload required" in FIG. 26. "Medium level work support" is the content with the second highest level of support after "review of workload" (support level 3), and is written as "work help (medium) required" in FIG. 26. "Low level work support" is the second highest level of support after "medium level work support" (support level 2), and is indicated as "low work help needed" in Figure 26. "Advice" is the second highest level of support after "low level work support" (support level 1), and is work support that provides work advice to the pilot MP. "No work support" is the lowest level of support (support level 0). "No work support" is work support when no work support is required for the pilot MP, and is indicated as "-" in Figure 26.

[0182] The controller 50 may determine one of a plurality of levels relating to the degree of impatience (e.g., the five levels shown in FIG. 26) corresponding to the psychological state information as the impatience quantitative value, and may determine one of a plurality of levels relating to productivity (e.g., the five levels shown in FIG. 26) corresponding to the productivity information as the productivity, and may determine the content of the work support based on the determined impatience quantitative value, the productivity, and the map shown in FIG. 26.

[0183] In the work support system 300B according to the second embodiment, the support content determination unit of the controller 50 may determine the content of the work support in consideration of not only the impatience quantitative value and the productivity but also the difficulty of the work. That is, the controller 50 may determine the content of the work support based on the impatience quantitative value, the productivity, and the difficulty of the work.

[0184] FIG. 27 is a diagram showing an example of a map used by the controller 50 to set the difficulty level of a task. FIG. 28 is a diagram showing two maps in which the contents of various task support are associated with the degree of impatience and productivity. The upper map in FIG. 28 is a map used when the task difficulty level is "Difficulty level 2," and the lower map in FIG. 28 is a map used when the task difficulty level is "Difficulty level 4." When the task difficulty level is set to five levels, for example, from difficulty level 1 to difficulty level 5, not only the two maps shown in FIG. 28 but also the maps not shown in the figure are set in advance for use in the cases of "Difficulty level 1," "Difficulty level 3," and "Difficulty level 5."

[0185] As shown in FIG. 27, the difficulty of a task is affected by, for example, the weather when the task is performed. Specifically, the difficulty of a task in rainy weather tends to be higher than the difficulty of a task in fine weather. The difficulty of a task is also affected by, for example, the hardness of the ground at the work site. The difficulty of a task when the ground is made of hard soil tends to be higher than the difficulty of a task when the ground is made of soft soil. The difficulty of a task is also affected by the content of the task. In the specific example shown in FIG. 27, a difficulty level is preset for each of a plurality of tasks including excavation work, ground leveling work, and slope forming work.

[0186] The controller 50 acquires difficulty information, which is information for determining the difficulty of a task. The difficulty information includes, for example, information on the weather, the firmness of the ground, the task content, and the like. The controller 50 may determine the task content by the above-mentioned method. The controller 50 may also determine the weather and the firmness of the ground based on, for example, information on the weather and information on the firmness of the ground inputted to an input device. The controller 50 may then determine the difficulty of the task based on the acquired difficulty information and, for example, a map shown in FIG. 27.

[0187] The controller 50 may select a map corresponding to the determined difficulty level from a plurality of maps including the two maps in FIG. 28, and determine the content of the work support based on the selected map, the quantitative impatience value, and the productivity.

[0188] In the work support system 300B according to the second embodiment, the support content determination unit of the controller 50 may determine the content of the work support by considering not only the impatience quantitative value, the productivity, and the difficulty of the work, but also the work skill of the operator MP. That is, the controller 50 may determine the content of the work support based on the impatience quantitative value, the productivity, the difficulty of the work, and the work skill. However, in this modified example, the controller 50 may determine the content of the work support based on the impatience quantitative value, the productivity, and the work skill without using the difficulty of the work.

[0189] FIG. 29 is a diagram showing an example of a map used to set the work skill of the operator MP. In the map shown in FIG. 29, the horizontal axis of the graph indicates the level of the work skill parameter correlated with the work skill, and the vertical axis of the graph indicates the level of the work skill. The map shown in FIG. 29 shows a relationship in which the level of the work skill decreases as the level of the work skill parameter decreases. In this map, the work skill is divided into five levels from skill level 1 (lowest level) to skill level 5 (highest level). The controller 50 can determine the work skill (skill level) of the operator MP using the value of the work skill parameter of the operator MP and the map shown in FIG. 29.

[0190] The work skill parameter may be, for example, the efficiency of the work performed by the operator MP, the accuracy of the work performed by the operator MP, or the accuracy of the operation by the operator MP given to the controller 72. The efficiency of the work may be, for example, a ratio of actual fuel consumption to an assumed fuel consumption assumed in advance in a specific work (efficiency of work = actual fuel consumption / assumed fuel consumption). The actual fuel consumption may be an average fuel consumption which is an average value of actual fuel consumption. The accuracy of the work may be a standard deviation of the height of the tip attachment 6 in the work. The controller 50 can determine the height of the tip attachment 6 based on, for example, information on the attitude of the working device 3. The controller 50 can determine the attitude of the working device 3 based on, for example, a detection result input to the controller 50 from an attitude detector (not shown). The accuracy of the operation may be an integrated value of the time during which a wasteful operation is performed in a specific work.

[0191] When a plurality of maps (e.g., five maps) corresponding to a plurality of skill levels (e.g., five skill levels) are preset, the controller 50 may determine the content of the work support as follows. Each of the plurality of maps is a map that associates the quantitative impatience value, the productivity, and the content of the work support. The controller 50 may select a map corresponding to the work skill parameter (or work skill) to be acquired from the plurality of maps, and determine the content of the work support based on the selected map, the quantitative impatience value, and the productivity.

[0192] Also, when a map as shown in Fig. 26 is set in advance, this map may be set as a map corresponding to skill level 1 as shown in Fig. 30 (the top map in Fig. 30), for example, and when the operation skill of the operator MP is skill level 2, a new map (the center map in Fig. 30) generated by sliding all 25 squares in the map shown in Fig. 26 by one square to the right may be used as a map corresponding to skill level 2. Similarly, when the operation skill of the operator MP is skill level 3, a new map (not shown) generated by sliding all 25 squares in the map shown in Fig. 26 by two squares to the right may be used as a map corresponding to skill level 3, for example, and when the operation skill of the operator MP is skill level 4, a new map (not shown) generated by sliding all 25 squares in the map shown in Fig. 26 by three squares to the right may be used as a map corresponding to skill level 4, for example. Similarly, if the operator MP's work skill is skill level 5, a new map (the bottom map in Figure 30) generated by sliding all 25 squares in the map shown in Figure 26 four squares to the right may be used as the map corresponding to skill level 5, for example.

[0193] The controller 50 may be configured to automatically present the contents of the work support to the work manager when the quantitative impatience value and productivity satisfy a preset condition. Fig. 31 is a diagram showing an example of a map that can be used by the controller 50 to determine whether or not to automatically notify the contents of the work support to the work manager or other related parties, using the degree of impatience and productivity of the operator MP when operating the construction machine 100.

[0194] The map shown in FIG. 31 includes an automatic notification area partitioned by the degree of impatience and productivity. This automatic notification area is set in advance so that the contents of the work support are automatically notified to the workers involved when the degree of impatience is high and productivity is low. That is, this automatic notification area is set in advance so that the contents of the work support are automatically notified to the workers involved when the quantitative impatience value is high and productivity is low. In this case, when a condition (a preset condition) that the quantitative impatience value and productivity are included in the automatic notification area is satisfied, the controller 50 automatically presents the contents of the work support to the work manager. On the other hand, when at least one of the quantitative impatience value and productivity is not included in the automatic notification area, that is, when the condition is not satisfied, the controller 50 does not present the contents of the work support to the work manager.

[0195] The controller 50 may change the automatic notification area according to the difficulty of the work, or according to the work skill (skill level) of the pilot MP. The automatic notification area may be set by a person involved in the work, such as a work manager.

[0196] [Third aspect] FIG. 32 is a block diagram showing a task support system 300C according to the third embodiment.

[0197] The work support system 300C shown in FIG. 32 includes a controller 50. The controller 50 includes a time series data acquisition unit, a promotion information transmission unit, and an improvement information determination unit. The time series data acquisition unit, the promotion information transmission unit, and the improvement information determination unit are each realized by the arithmetic processing device executing a control program stored in the memory in the controller 50. The time series data acquisition unit, the promotion information transmission unit, and the improvement information determination unit are examples of a command content determination unit in the work support system 300 shown in FIG. 1. The promotion information transmission unit is an example of an attendant status management unit in the work support system 300CD shown in FIG. 6. The improvement information determination unit is an example of a control content determination unit in the work support system 300CD shown in FIG. 6.

[0198] The time series data acquisition unit acquires psychological state time series data, which is data regarding time-series changes in the psychological state, based on the psychological state information, which is information correlated with the psychological state of the operator MP when operating at least one of the construction machine 100 and the simulator 200.

[0199] The promotion information transmission unit transmits change promotion information, which is information for encouraging the operator MP to change his / her psychological state, at least when operating the construction machine 100 or when operating the simulator 200.

[0200] The improvement information determination unit determines the content (instruction content) of the improvement information, which is information to be transmitted in order to improve the psychological state of the operator MP when operating the construction machine 100, using data regarding changes in the psychological state before and after the transmission of the change promotion information.

[0201] In the work support system 300C of the third aspect, the psychological state information may be information that correlates with the psychological state of the operator MP when operating the construction machine 100, or may be information that correlates with the psychological state of the operator MP when operating the simulator 200.

[0202] FIG. 33 is a flowchart showing an example of calculation processing performed by the controller 50 of the work support system 300C according to the third embodiment.

[0203] When operating the simulator 200, the controller 50 sequentially acquires, in a time series, the psychological state information relating to the psychological state of the pilot MP input from the psychological state acquirer 60. In parallel with acquiring the psychological state information in a time series, the controller 50 transmits change promotion information for encouraging the pilot MP to change his / her psychological state. The controller 50 can acquire the psychological state time series data, which is data relating to the time series change in the psychological state, by storing the psychological state information acquired in a time series in association with the timing of transmitting the change promotion information (step S51).

[0204] The controller 50 determines the contents of the improvement information (the contents of the instruction) using the data on the change in the psychological state before and after the transmission of the change promotion information (step S52).

[0205] The controller 50 repeatedly performs the processes of steps S51 to S52 during the system startup.

[0206] The controller 50 may present the contents of the determined improvement information (instruction contents) to the work manager.

[0207] The controller 50 inputs a psychological state improvement command to the control object so that the improvement information is transmitted at an appropriate timing when the operator MP actually operates the construction machine 100 (actual machine). The control object operates in accordance with the psychological state improvement command input from the controller 50. This improves the psychological state of the operator MP when working with the construction machine 100.

[0208] Next, a modified example of the third embodiment will be described. FIG. 34 is a diagram showing a work support system 300C according to a modified example of the third embodiment. In the work support system 300C according to the modified example shown in FIG. 34, the controller 50 includes a simulator-side controller unit 50A and a machine-side controller unit 50B. The simulator-side controller unit 50A may be mounted on the simulator 200 (see FIG. 2), or may be disposed at a location separate from the simulator 200. The machine-side controller unit 50B may be mounted on the construction machine 100. When the construction machine 100 is remotely operated, the machine-side controller unit 50B may be disposed at a remote location away from the construction machine 100.

[0209] The simulator-side controller unit 50A includes a first time-series data acquisition unit (impatience measurement unit), a first promotion information transmission unit (instruction unit), a first improvement information determination unit (not shown), a first operator judgment unit, and a first information acquisition unit (task content acquisition unit). The machine-side controller unit 50B may include a second time-series data acquisition unit (impatience measurement unit), a second promotion information transmission unit (instruction unit), a second improvement information determination unit (not shown), a second operator judgment unit, and a second information acquisition unit (task content acquisition unit).

[0210] The first time-series data acquisition unit acquires psychological state time-series data, which is data related to time-series changes in the psychological state, based on the psychological state information, which is information correlated with the psychological state of the pilot MP when operating the simulator 200. FIG. 35 is a diagram showing an example of psychological state time-series data. FIG. 35 will be described later. In addition, in parallel with the acquisition of the psychological state time-series data by the first time-series data acquisition unit, a first incidental situation acquisition unit (not shown) may acquire incidental situation time-series data, which is data related to time-series changes in the incidental situation when operating the simulator 200. However, in the third aspect, it is sufficient that at least the psychological state time-series data is acquired by the first time-series data acquisition unit, and the incidental situation time-series data may not be acquired by the incidental situation acquisition unit. In the third aspect, the first incidental situation acquisition unit is not an essential configuration in the simulator-side controller unit 50A and can be omitted.

[0211] The second time-series data acquisition unit acquires psychological state time-series data, which is data related to time-series changes in the psychological state, based on the psychological state information, which is information correlated with the psychological state of the operator MP when operating the construction machine 100. In addition, in parallel with the acquisition of the psychological state time-series data by the second time-series data acquisition unit, a second incidental situation acquisition unit (not shown) may acquire incidental situation time-series data, which is data related to time-series changes in the incidental situation when operating the construction machine 100. This incidental situation time-series data may include, for example, a detection result input from an incidental situation detector 78 to the controller 50. The incidental situation detector 78 may be an image detection device such as a camera that acquires an image of the actual work site where the construction machine 100 is placed. However, in the third aspect, it is sufficient that at least the psychological state time-series data is acquired by the second time-series data acquisition unit, and the incidental situation time-series data may not be acquired by the second incidental situation acquisition unit. In the third aspect, the second incidental situation acquisition unit is not an essential configuration in the machine-side controller unit 50B and can be omitted.

[0212] The first promotion information transmission unit controls the operation of the transmitter so as to transmit change promotion information, which is information for prompting the operator MP to change his / her psychological state when operating the simulator 200. The psychological state time-series data shown in Fig. 35 includes data on the change in psychological state before and after the transmission of the change promotion information.

[0213] The second promotion information transmission unit may control the operation of the transmitter so as to transmit change promotion information, which is information for encouraging the operator MP to change his / her psychological state when operating the construction machine 100.

[0214] The transmitter may be a part of the simulator 200, or may be a part of the construction machine 100. The transmitter may be the alarm, or may be another device capable of transmitting change promotion information.

[0215] The first improvement information determination unit may determine the content of the improvement information (the teaching content) by using data on the change in the psychological state before and after the transmission of the change promotion information when operating the simulator 200. The improvement information is information to be transmitted in order to improve the psychological state of the operator MP when operating the construction machine 100.

[0216] When the first improvement information determination unit determines the content of the improvement information (instruction content), the controller 50 controls the control object so that the improvement information determined by the first improvement information determination unit when operating the simulator 200, i.e., the instruction content optimal for the operator MP, is transmitted to the operator MP when the operator MP actually operates the construction machine 100. In this case, the control object may be, for example, the alarm. The alarm may include a first display 73 and an audio device 74. The alarm may be disposed in the cab 7.

[0217] The second improvement information determination unit may determine the content of the improvement information (instruction content) by using data on the change in the psychological state before and after the transmission of the change promotion information when operating the construction machine 100. The improvement information is information to be transmitted in order to improve the psychological state of the operator MP when operating the construction machine 100.

[0218] When the second improvement information determination unit determines the content of the improvement information (instruction content), the controller 50 may control the control object so that the improvement information determined by the second improvement information determination unit when operating the construction machine 100, i.e., the instruction content that is optimal for the operator MP, is transmitted to the operator MP when the operator MP is actually operating the construction machine 100.

[0219] The timing at which the change promotion information is transmitted is not particularly limited. The controller 50 may control the operation of the transmitter so that the change promotion information is transmitted in response to a change in the quantitative impatience value. Specifically, for example, the controller 50 may control the operation of the transmitter so that the change promotion information is transmitted when the quantitative impatience value is equal to or greater than a predetermined threshold value. The controller 50 may also control the operation of the transmitter so that the change promotion information is transmitted when the quantitative impatience value increases and reaches a peak. The controller 50 may also control the operation of the transmitter so that the change promotion information is transmitted when the increase in the quantitative impatience value per unit time is equal to or greater than a predetermined threshold value. The controller 50 may also control the operation of the transmitter so that the change promotion information is transmitted randomly.

[0220] Furthermore, the controller 50 may perform control to present information about work support, including the determined improvement information, to a person involved in the work, such as a work manager.

[0221] The first operator determination unit determines and identifies the operator MP who operates the simulator 200. The second operator determination unit determines and identifies the operator MP who operates the construction machine 100. Each of the first operator determination unit and the second operator determination unit may determine and identify the operator MP based on, for example, identification information of the operator MP inputted to a predetermined input device. Also, each of the first operator determination unit and the second operator determination unit may determine and identify the operator MP based on, for example, image information for authenticating the operator MP.

[0222] The first information acquisition unit and the second information acquisition unit may each acquire information related to work content. Specifically, the information is as follows.

[0223] The first information acquisition unit acquires information (work content information) on the work content by the simulator 200. The work content information may include, for example, information on the operation (operation input) received by the controller 72 of the control device 70. In this case, the first information acquisition unit may determine the work content based on the information on the operation (operation input) received by the controller 72 of the control device 70. The work content information may also include, for example, operation data of the simulator 200. In this case, the first information acquisition unit may determine the work content based on, for example, operation data of the construction machine model 100a in the virtual space of the simulator 200. The operation data may include operation information of the construction machine model 100a associated with the controller 72 receiving the operation performed by the operator MP. The first information acquisition unit may determine the work content by analyzing an image (for example, an image of the work site model 400a, the construction machine model 100a, etc.) displayed on the first display 73 and / or the second display 76. In addition, when a person involved in the work, such as a pilot MP or a work manager, inputs information to a predetermined input device to identify the work content, the work content information may include information input to the input device. In this case, the first information acquisition unit may determine the work content based on the information input to the input device.

[0224] The second information acquisition unit acquires information (work content information) on the work content by the construction machine 100. The work content information may include, for example, information on the operation (operation input) received by the controller 72 of the control device 70. In this case, the second information acquisition unit may determine the work content based on the information on the operation (operation input) received by the controller 72 of the control device 70. The work content information may also include, for example, operation data of the construction machine 100. In this case, the second information acquisition unit may determine the work content based on the operation data of the construction machine 100. The operation data may include information on the operation of the construction machine 100 associated with the controller 72 receiving the operation performed by the operator MP. For example, the operation data may include information on the revolving operation of the upper revolving body 2 relative to the lower traveling body 1, and may include information on the operation of the working device 3. Specifically, the operation data may include information on the operation of at least one of the boom 4, the arm 5, and the tip attachment 6, and may include information on the extension and retraction operation of at least one of a plurality of cylinders that drive the boom 4, the arm 5, and the tip attachment 6. The operation data may include an image of the work site captured by a camera mounted on the construction machine 100 for capturing an image of the work site, and / or a camera installed at the work site for capturing an image of the work site so as to include the construction machine 100. The image of the work site may be an image displayed on the first display 73 and / or the second display 76. The second information acquisition unit may analyze the image of the work site to determine the work content. In addition, when a person involved in the work, such as the operator MP or the work manager, inputs information to a predetermined input device to identify the work content, the work content information may include information input to the input device. In this case, the second information acquisition unit may determine the work content based on the information input to the input device.

[0225] Next, a flow of work support using the work support system 300C according to the third embodiment will be described using several specific examples 1 to 4. In the following, a case where the content of the improvement information (teaching content) is determined when the operator MP operates the simulator 200 will be described as an example.

[0226] [Example 1] (Determining the content of improvement information) When the pilot MP is operating the simulator 200, the controller 50 transmits the change promotion information to the pilot MP in parallel with acquiring the psychological state information in time series. The controller 50 acquires the psychological state time series data by correlating and storing the psychological state information acquired in time series with the timing of transmitting the change promotion information. The controller 50 determines the optimal teaching content (content of improvement information) for the pilot MP using data related to the change in the psychological state before and after the transmission of the change promotion information.

[0227] (Dissemination of improvement information) Then, the controller 50 inputs a psychological state improvement command to the controlled object so that improvement information of the determined teaching content is transmitted to the operator MP when the operator MP is operating the construction machine 100 at an actual work site.

[0228] [Example 2] The second example differs from the first example in that the pilot MP is identified and information about the identified pilot MP is used.

[0229] (Identifying the simulator operator) When the pilot MP operates the simulator 200, the controller 50 determines and identifies the pilot MP who operates the simulator 200. The controller 50 stores information about the identified pilot MP. The identified pilot MP is hereinafter referred to as pilot MP1.

[0230] (Determining the content of improvement information) When the operator MP1 is operating the simulator 200, the controller 50 determines the optimum teaching contents (contents of improvement information) for the operator MP1 in the same manner as in the first specific example.

[0231] (Identification of the operator of construction machinery) The controller 50 determines and identifies the operator MP who operates the construction machine 100 at the actual work site. The controller 50 stores information about the identified operator MP.

[0232] (Dissemination of improvement information) When the identified operator MP (operator MP who operates the construction machine 100) is the operator MP1 identified when operating the simulator 200, the controller 50 inputs a psychological state improvement command to the control target so that improvement information of the determined teaching content is transmitted to the operator MP1 when the operator MP1 actually operates the construction machine 100. On the other hand, when the identified operator MP is not the operator MP1 identified when operating the simulator 200, the controller 50 does not perform control to transmit improvement information when the operator MP is operating the actual construction machine 100. However, when general-purpose improvement information, which is improvement information with high versatility for various operators, is set in advance in the controller 50, the controller 50 may input a psychological state improvement command to the control target so that general-purpose improvement information is transmitted to the operator MP when the operator MP is operating the actual construction machine 100, even if the identified operator MP is not the operator MP1 identified when operating the simulator 200.

[0233] [Example 3] Specific Example 3 differs from Specific Example 1 in that information related to work content is used.

[0234] (Identifying the work content in the simulator) When the operator MP operates the simulator 200, the controller 50 specifies the work content (training content) to be performed by the operator MP. The controller 50 stores the specified work content.

[0235] (Determining the content of improvement information) When the operator MP operates the simulator 200, the controller 50 determines the optimum teaching content (improvement information content) for the operator MP in the same manner as in Example 1. The controller 50 may store the identified task content and the optimum teaching content (improvement information content) for the operator MP in association with each other.

[0236] (Identifying the actual work carried out by construction machinery) When the operator MP operates the construction machine 100, the controller 50 specifies the work content to be performed by the operator MP.

[0237] (Dissemination of improvement information) When the work content (actual work content) specified when operating the construction machine 100 is the same as the work content (training content) specified when operating the simulator 200, the controller 50 inputs a psychological state improvement command to the control target so that improvement information of the teaching content associated with the work content is transmitted to the operator MP when the operator MP is actually operating the construction machine 100. On the other hand, when the actual work content differs from the training content, the controller 50 does not perform control to transmit improvement information when the operator MP is actually operating the construction machine 100.

[0238] [Example 4] Example 4 differs from Examples 2 and 3 in that it utilizes both information related to the operator MP and information related to the work content.

[0239] (Identifying the simulator operator) When the operator MP is operating the simulator 200, the controller 50 identifies the operator MP1 in the same manner as in the second specific example, and stores information about the operator MP1.

[0240] (Identifying the work content in the simulator) When the operator MP1 operates the simulator 200, the controller 50 specifies the work content (training content) to be performed by the operator MP1. The controller 50 stores the specified work content and information related to the operator MP1 in association with each other.

[0241] (Determining the content of improvement information) When the operator MP1 operates the simulator 200, the controller 50 determines the optimum teaching contents (improvement information contents) for the operator MP1 in the same manner as in Example 1. The controller 50 may store the identified task contents in association with information on the operator MP1 and / or the optimum teaching contents (improvement information contents) for the operator MP1.

[0242] (Identification of the operator of construction machinery) The controller 50 determines and identifies the operator MP who operates the construction machine 100 at the actual work site. The controller 50 stores information about the identified operator MP.

[0243] (Identifying the actual work carried out by construction machinery) When the operator MP operates the construction machine 100, the controller 50 specifies the work content to be performed by the operator MP. The controller 50 stores the specified work content and information about the operator MP in association with each other.

[0244] (Dissemination of improvement information) If the identified operator MP is the operator MP1 identified when operating the simulator 200, and the work content (actual work content) identified when operating the construction machine 100 is the same as the work content (training content) identified when operating the simulator 200, the controller 50 inputs a psychological state improvement command to the control target so that improvement information of the determined teaching content is transmitted to the operator MP1 when the operator MP1 is actually operating the construction machine 100. On the other hand, if the identified operator MP is not the operator MP1, the controller 50 does not perform control to transmit improvement information when the operator MP is operating the actual construction machine 100. Also, if the actual work content is different from the training content, the controller 50 does not perform control to transmit improvement information when the operator MP is operating the actual construction machine 100. However, when the general improvement information is preset in the controller 50, the controller 50 may input a psychological state improvement command to the control object so that the general improvement information is transmitted to the operator MP when the operator MP is operating the actual construction machine 100, even if the identified operator MP is not the operator MP1 identified when operating the simulator 200, if the actual work content is the same as the training content.

[0245] In the above specific examples 1 to 4, we have explained the case where the content of the improvement information (instruction content) is determined when the operator MP operates the simulator 200, but the content of the improvement information (instruction content) may also be determined when the operator MP operates the construction machine 100.

[0246] [Example of acquiring psychological state time series data] Next, a specific example of acquisition of psychological state time series data will be described. In this modified example, the controller 50 may acquire the psychological state time series data, for example, as follows.

[0247] In a modified example of the third aspect described below, the controller 50 may perform control such that a plurality of pieces of change promotion information are transmitted at different timings, compare the improvement effects of the psychological state resulting from the transmission of the plurality of pieces of change promotion information, and determine the one with the greatest improvement effect as the improvement information. The controller 50 performs control such that a plurality of pieces of change promotion information are transmitted to the pilot MP at different timings, and thus can obtain the respective improvement effects of the plurality of pieces of change promotion information. This allows the controller 50 to compare these improvement effects and determine the change promotion information with the greatest improvement effect as the improvement information.

[0248] Figure 35 shows the time series change in the quantitative impatience value when the operator MP is operating the simulator 200, that is, the time series change in the quantitative impatience value during training to operate a construction machine. In Figure 35, training using the simulator 200 starts at time t0 and ends at time t7. During the time period of training using the simulator 200 (the time period from time t0 to time t7), the controller 50 sequentially acquires the psychological state information from the psychological state acquirer 60.

[0249] The controller 50 controls the transmitter so that the plurality of pieces of change promotion information are transmitted at different times during the training period. The controller 50 compares the improvement effects of the plurality of pieces of change promotion information on the degree of impatience by transmitting the plurality of pieces of change promotion information, and determines the change promotion information with the highest improvement effect as the improvement information.

[0250] In the specific example of Figure 35, the controller 50 controls the operation of the transmitter so that the change promotion information is transmitted in each of a first time period from time t1 to time t2, a second time period from time t3 to time t4, and a third time period from time t5 to time t6.

[0251] In the first time period, an alarm sound (first change promotion information) is emitted from the audio device 74. In the second time period, subtitles (second change promotion information) are displayed on the first display 73. In the third time period, voice (third change promotion information) is emitted from the audio device 74. The text displayed in the second time period is a subtitle (e.g., a text such as "Please remain calm and operate the vehicle") created in advance to reduce the level of impatience of the pilot MP. The voice emitted in the third time period is a voice (e.g., a text such as "Please remain calm and operate the vehicle") created in advance to reduce the level of impatience of the pilot MP.

[0252] 35 acquired by the controller 50 includes data on changes in the degree of impatience (changes in the psychological state) before and after the transmission of each piece of change promotion information. Using the psychological state time series data, the controller 50 calculates a first impatience change amount (Δy1) which is the change in the degree of impatience caused by the first change promotion information (alarm sound) transmitted in a first time period, a second impatience change amount (Δy2) which is the change in the degree of impatience caused by the second change promotion information (subtitles) transmitted in a second time period, and a third impatience change amount (Δy3) which is the change in the degree of impatience caused by the third change promotion information (audio) transmitted in a third time period.

[0253] Fig. 36 is a diagram in which the first to third impatience change amounts are organized in a table. As shown in Fig. 36, the first impatience change amount (Δy1) is a value (positive value) that increases the degree of impatience, the second impatience change amount (Δy2) is a value (negative value) that decreases the degree of impatience, and the third impatience change amount (Δy3) is a value (negative value) that decreases the degree of impatience. The absolute value of the second impatience change amount (Δy2) is greater than the absolute value of the third impatience change amount (Δy3) (|Δy2|>|Δy3|).

[0254] The controller 50 may determine, as the improvement information, the change promotion information that has the largest reduction in the degree of impatience among the multiple acquired changes in impatience.

[0255] Furthermore, the controller 50 may determine, as the improvement information, the change promotion information corresponding to the impatience change amount whose absolute value is closest to the absolute value of the difference between the impatience target value and the actual impatience level and whose sign is opposite to the sign of the difference, among the multiple impatience change amounts obtained.

[0256] Fig. 37 shows an example of time-series data of changes in the degree of impatience (psychological state) of the operator MP when he / she is actually operating the construction machine 100 (actual machine). A target degree of impatience (target impatience value) is set for the operator MP, and this target impatience value is indicated by a dashed line in Fig. 37.

[0257] 37, the degree of impatience of the pilot MP starts to increase from time t8, and the difference between the target impatience value and the actual quantitative impatience value at time t9 (quantitative impatience value-target impatience value) is, for example, "40." Therefore, the controller 50 determines, as the improvement information, the second change promotion information corresponding to the amount of impatience change ("-50") whose absolute value is closest to the absolute value of the difference and has the opposite sign to the difference among the first to third amounts of impatience change.

[0258] Next, the controller 50 controls the annunciator to transmit the determined improvement information (second change promotion information: subtitles). This changes the degree of impatience of the pilot MP (decreases by Δy in FIG. 37), and makes it possible to appropriately control the annunciator to be controlled so that the actual quantitative impatience value approaches the target impatience value.

[0259] In the third aspect, an additional condition for determining the content (instruction content) of the improvement information may be further set. In Fig. 38, the additional condition is, for example, a condition that the second change promotion information cannot be selected as the improvement information while the pilot MP is working while gazing upward. In this case, the controller 50 determines the third change promotion information, which is the next most suitable change promotion information after the second change promotion information, as the improvement information.

[0260] In the third aspect, the time-series data acquisition unit may acquire psychological state time-series data, which is data relating to time-series changes in the psychological state, based on the psychological state information, which is information correlated with the psychological state of the operator MP when operating the construction machine 100, not when operating the simulator 200. In this case, the second time-series data acquisition unit (impatience measurement unit), second promotion information transmission unit (instruction unit), second improvement information determination unit, and second operator judgment unit in the machine-side controller unit 50B perform the same control as the above-mentioned control performed by the first time-series data acquisition unit, first promotion information transmission unit, first improvement information determination unit, and first operator judgment unit in the simulator-side controller unit 50A.

[0261] [Fourth aspect] FIG. 39 is a block diagram showing a task support system 300D according to the fourth embodiment.

[0262] The work support system 300D shown in FIG. 39 includes a controller 50. The controller 50 includes a time series data acquisition unit, an incidental situation acquisition unit, and a training content determination unit. The time series data acquisition unit, the incidental situation acquisition unit, and the training content determination unit are each realized by the arithmetic processing device executing a control program stored in the memory in the controller 50. The time series data acquisition unit, the incidental situation acquisition unit, and the training content determination unit are examples of a command content determination unit in the work support system 300 shown in FIG. 1. The incidental situation acquisition unit is an example of an incidental situation management unit in the work support system 300CD shown in FIG. 6. The training content determination unit is an example of a control content determination unit in the work support system 300CD shown in FIG. 6.

[0263] The time series data acquisition unit acquires psychological state time series data, which is data regarding time-series changes in the psychological state, based on the psychological state information, which is information correlated with the psychological state of the operator MP when operating at least one of the construction machine 100 and the simulator 200.

[0264] The incidental situation acquisition unit acquires incidental situation information (data related to the incidental situation) related to changes in the incidental situation. Specifically, for example, the incidental situation acquisition unit acquires incidental situation time-series data which is data related to time-series changes in the incidental situation. The incidental situation time-series data is data related to time-series changes in the incidental situation during at least one of the operation of the construction machine 100 and the operation of the simulator.

[0265] The information on the change in the incidental situation (accompanying situation information) may be information on the change in the surrounding situation. The information on the change in the surrounding situation may be, for example, information on the change in the surrounding situation of the construction machine 100, information on the change in the surrounding situation of the construction machine model 100a in the virtual space constructed by the simulator 200, or information on the change in the surrounding situation of the operator MP. The incidental situation information may be information on the change in the work content by the construction machine 100. A specific example of the incidental situation information is information on the distance D between the construction machine model 100a and a surrounding object model, which will be described later. In this case, data on the time-series change in the distance D shown in FIG. 42, which will be described later, is an example of incidental situation time-series data (an example of the change in the incidental situation). The incidental situation information may also be information on the distance between the construction machine 100 and a surrounding object at an actual work site. In this case, the controller 50 (accompanying situation acquisition unit) may acquire the information on the distance based on a detection result by a sensor capable of measuring the distance between the construction machine 100 and a surrounding object. The controller 50 (accompanying condition acquisition unit) may acquire information regarding the distance by analyzing an image of the work site acquired by a camera.

[0266] The training content determination unit determines training content for training the pilot MP using the psychological state time series data and the attendant situation time series data.

[0267] In the work support system 300D of the fourth aspect, the psychological state information may be information that correlates with the psychological state of the operator MP when operating the construction machine 100, or may be information that correlates with the psychological state of the operator MP when operating the simulator 200.

[0268] FIG. 40 is a flowchart showing an example of calculation processing performed by the controller 50 of the work support system 300D according to the fourth embodiment.

[0269] The controller 50 sequentially stores the psychological state information on the psychological state of the pilot MP input from the psychological state acquirer 60, thereby acquiring the psychological state time-series data which is data on the time-series change of the psychological state (step S61).

[0270] In parallel with the acquisition of the psychological state time-series data, the controller 50 acquires attendant condition time-series data, which is data regarding time-series changes in the attendant conditions (step S62).

[0271] The controller 50 determines the training contents for training the pilot MP using the psychological state time-series data and the attendant situation time-series data (step S63).

[0272] The controller 50 inputs a training command, which is a command corresponding to the determined training content, to the controlled object (step S64).

[0273] The controlled object performs an operation in accordance with a training command input from the controller 50. This can improve the psychological state of the operator MP during work using the construction machine 100.

[0274] The controller 50 presents the determined training content to the work manager (step S65).

[0275] The controller 50 repeatedly performs the processes of steps S61 to S65 during the system startup.

[0276] Next, a modified example of the fourth embodiment will be described. FIG. 41 is a diagram showing a work support system 300D according to a modified example of the fourth embodiment. In the work support system 300D according to the modified example shown in FIG. 41, the controller 50 includes a simulator-side controller unit 50A and a machine-side controller unit 50B. The simulator-side controller unit 50A may be mounted on the simulator 200 (see FIG. 2), or may be disposed at a location separate from the simulator 200. The machine-side controller unit 50B may be mounted on the construction machine 100. When the construction machine 100 is remotely operated, the machine-side controller unit 50B may be disposed at a remote location away from the construction machine 100.

[0277] The simulator-side controller unit 50A may include a first time-series data acquisition unit (impatience measurement unit), a training content determination unit (task generation unit), a first incidental situation acquisition unit, and a first operator determination unit. The machine-side controller unit 50B may include a second time-series data acquisition unit (impatience measurement unit), a second incidental situation acquisition unit, and a second operator determination unit. The simulator-side controller unit 50A may further include a first information acquisition unit (task content acquisition unit). The machine-side controller unit 50B may further include a second information acquisition unit (task content acquisition unit).

[0278] The first time-series data acquisition unit may acquire psychological state time-series data that is data regarding time-series changes in the psychological state of the pilot MP based on the psychological state information that is information correlated with the psychological state of the pilot MP when operating the simulator 200. In parallel with acquisition of the psychological state time-series data by the first time-series data acquisition unit, the first incidental condition acquisition unit may acquire incidental condition time-series data that is data regarding time-series changes in incidental conditions when operating the simulator 200.

[0279] The second time-series data acquisition unit may acquire psychological state time-series data, which is data regarding time-series changes in the psychological state of the operator MP, based on the psychological state information, which is information correlated with the psychological state of the operator MP, when operating the construction machine 100. In parallel with acquisition of the psychological state time-series data by the second time-series data acquisition unit, the second incidental condition acquisition unit may acquire incidental condition time-series data, which is data regarding time-series changes in the incidental conditions, when operating the construction machine 100. This incidental condition time-series data may include, for example, a detection result input from the incidental condition detector 78 to the controller 50. The incidental condition detector 78 may be an image detection device, such as a camera, that acquires images of the actual work site where the construction machine 100 is placed.

[0280] The training content determination unit (task generation unit) determines training content for training the pilot MP using the psychological state time-series data and the attendant situation time-series data.

[0281] The first operator determination unit determines and identifies the operator MP who operates the simulator 200. The second operator determination unit determines and identifies the operator MP who operates the construction machine 100. Each of the first operator determination unit and the second operator determination unit may determine and identify the operator MP based on, for example, identification information of the operator MP inputted to a predetermined input device. Also, each of the first operator determination unit and the second operator determination unit may determine and identify the operator MP based on, for example, image information for authenticating the operator MP.

[0282] The first information acquisition unit and the second information acquisition unit may each acquire information regarding the work content. The first information acquisition unit and the second information acquisition unit in the fourth aspect are similar to the first information acquisition unit and the second information acquisition unit described in the third aspect, and therefore detailed description thereof will be omitted.

[0283] In the fourth aspect, when the operator MP operates the construction machine 100, the operation that the operator MP is not good at may be identified and stored in the database. Specifically, for example, the second information acquisition unit sequentially determines the operation content of the construction machine 100, and the second time-series data acquisition unit acquires the psychological state time-series data of the operator MP. Then, when the difference between the target impatience value and the actual quantitative impatience value in the psychological state time-series data of the operator MP becomes larger than a predetermined reference value, the operation content performed by the construction machine 100 operated by the operator MP may be identified as the operation that the operator MP is not good at. Here, information on the work environment when the operation that the operator MP is not good at is identified may be associated with the operation that the operator MP is not good at and stored in the database. The work environment may include, for example, information on the position of the construction machine 100 and / or the attitude of the construction machine 100, and may include information on the size and / or arrangement of objects present around the construction machine 100 at the work site. The work environment may be captured by a camera mounted on the construction machine 100 and / or a camera installed at the work site.

[0284] In addition, in the fourth aspect, when the operator MP who operates the simulator 200 operates the virtual construction machine model 100a, the operator MP's weak task may be identified and stored in the database. Specifically, for example, the first information acquisition unit sequentially determines the task content of the construction machine model 100a, and the first time-series data acquisition unit acquires the psychological state time-series data of the operator MP. Then, when the difference between the target impatience value and the actual quantitative impatience value in the psychological state time-series data of the operator MP becomes larger than a predetermined reference value, the task content performed by the construction machine model 100a operated by the operator MP may be identified as the weak task of the operator MP. Here, information on the situation of the work site model 400a including the object model arranged around the construction machine model 100a when the weak task of the operator MP is identified may be associated with the weak task of the operator MP and stored in the database.

[0285] When the simulator 200 is started, the simulator 200 trains the operator MP by having the operator MP perform one or more work contents using the virtual work site model 400a and the virtual construction machine model 100a, for example. The one or more work contents may be preset in the simulator 200. The one or more work contents may be selected from a plurality of preset options based on an input by a person involved in the work, such as the operator MP. In addition, when general or statistical data (general data) such as data for identifying work contents that general operators are not good at, data for identifying work contents that general operators tend to get impatient, etc. are stored in the database, the one or more work contents may be selected by the controller 50 based on the general data. In addition, when past work history data of a specific operator MP, such as data for identifying work contents that a specific operator MP is not good at, data for identifying work contents that a specific operator MP tends to get impatient, etc. are stored in the database, the one or more work contents may be selected by the controller 50 based on the past work history data. The database may be a memory of the simulator 200, a memory of the management device 500, or a memory of another device. The past work history data of the operator MP may be work history data when the operator MP operated the simulator 200, or may be work history data when the operator MP operated the construction machine 100. The past work history data may be psychological state time series data.

[0286] In the simulator 200, a virtual work site model 400a and a virtual construction machine model 100a stored in a database as training contents according to the work contents are reproduced in the simulator 200. For example, information such as the posture and / or state of the construction machine model 100a, and the size and / or arrangement of an object model arranged around the construction machine model 100a in the work site model 400a is changed according to the contents stored in the database and reproduced in the simulator 200. For example, the work site model 400a may be reproduced according to a work site stored in a database when the construction machine 100 is operated. In this case, the posture of the construction machine model 100a may be adjusted and arranged in the work site model 400a based on the position and / or posture of the construction machine 100 stored in the database, and the object model may be arranged in the work site model 400a based on the size and / or arrangement of an object existing around the construction machine 100 stored in the database. Furthermore, the arrangement of the work site model 400a, the construction machine model 100a, and the object model may be reproduced in the simulator 200 based on the work site model 400a including the construction machine model 100a and the object model stored in the database when the simulator 200 is operated. During training with the simulator 200, the distance D between the construction machine model 100a and the surrounding object models changes in various ways depending on the operation by the operator MP that is received by the controller 72 of the control device 70. The controller 50 (the first incidental situation acquisition unit and / or the second incidental situation acquisition unit) sequentially acquires information regarding the distance D when the simulator is operated, i.e., during training with the simulator 200.

[0287] The top graph in Fig. 42 is a diagram showing an example of data on time-series changes in the distance D between the construction machine model 100a and the surrounding object models when the simulator is being operated, i.e., during training using the simulator 200. During training using the simulator 200, the controller 50 records an approach time period, which is a time period (time range) during which the distance D is equal to or less than a preset reference value Ds. In the specific example of Fig. 42, the approach time period is the time period between time t11 and time t12.

[0288] The graph in the center of Fig. 42 shows time-series data of operations (e.g., lever operations) performed by the operator MP on the controller 72 of the control device 70 during training using the simulator 200. The graph in the center of Fig. 42 shows that a number of operations are performed in this order: excavation work, earth removal work, first movement work (traveling on flat ground), second movement work (traveling on a slope), and slope leveling work.

[0289] The bottom graph in FIG. 42 shows the time series change in the degree of impatience (mental state) of the operator MP during training with the simulator 200. The controller 50 uses this psychological state time series data to identify and store the maximum value of the quantitative impatience value in the time period when each of the multiple tasks was performed. The bottom graph in FIG. 42 shows the maximum value P1 of the quantitative impatience value in the time period of the excavation task, the maximum value P2 of the quantitative impatience value in the time period of the earth removal task, the maximum value P3 of the quantitative impatience value in the time period of the first movement task, the maximum value P4 of the quantitative impatience value in the time period of the second movement task, and the maximum value P5 of the quantitative impatience value in the time period of the slope leveling task. FIG. 43 is a diagram in which some of the identified maximum values ​​are organized in a table.

[0290] 42 shows that the quantitative impatience value was highest during the first movement task (driving task on flat ground) performed in the time period corresponding to the approach time period (from time t11 to time t12) when the distance D was equal to or less than the reference value Ds. In other words, the pilot MP tends to be more impatient during driving tasks on flat ground.

[0291] The controller 50 determines the training content for training the operator MP to be a driving operation on flat ground based on the data shown in FIG. 42, which includes the psychological state time series data and the attendant situation time series data.

[0292] Then, the controller 50 reproduces training content suitable for the operator MP, i.e., driving work on flat ground, in the simulator 200, as shown in Fig. 44. This allows the operator MP to become accustomed to work that is likely to increase the degree of impatience (driving work on flat ground), and the operator MP is prevented from becoming impatient during the work.

[0293] Furthermore, the training content reproduced in the simulator 200 may be selectable by the operator MP or other related parties in the work. Figure 45 illustrates a case where the operator MP selects slope leveling work as the training content.

[0294] Fig. 46 is a diagram showing how close the actual quantitative impatience value of the pilot MP is to the target impatience value as a result of training in the simulator 200. In Fig. 46, the dashed line indicates data before training, and the solid line indicates data after training. The post-training data may be stored in the database. The controller 50 may perform control to permit the pilot MP to work on the actual machine when the post-training data is within a preset allowable range.

[0295] Fig. 47 is a graph comparing time series data of the quantitative impatience value of the driver MP with time series data of the quantitative impatience value of a driver MP' (expert) other than the driver MP, and comparing the lever operation of the driver MP with the lever operation of the driver MP'. The work support system 300D according to the modified example of the fourth aspect may be configured so that the driver MP can view the comparison data as shown in Fig. 47. This allows the driver MP to learn the relationship between changes in the psychological state of the expert and differences in the lever operation of the controller 72.

[0296] In the work support system 300D according to the fourth embodiment, when the database does not contain sufficient time series data on the pilot MP, the controller 50 may statistically process the time series data of another pilot MP' and use it for the pilot MP. This makes it possible to effectively train the pilot MP by utilizing the characteristics of the other pilot MP' (e.g., characteristics such as a tendency for performance to decrease in a specific task, or an increased degree of impatience in another specific task). Therefore, even if the pilot MP is, for example, a beginner with little work experience and has little past time series data, it is possible to train (learn) about impatience through simulation.

[0297] In a fourth aspect, the controller 50 may be configured to identify the work content performed during training with the simulator 200, for example, by using time-series data of operations by the pilot MP, such as that shown in the central graph of FIG. 42.

[0298] Next, a more preferable work support using the work support system 300D according to the fourth embodiment will be described with a specific example.

[0299] In the fourth aspect, the controller 50 preferably presents the situation in which the pilot MP should practice so as to be easily recognized by the pilot MP.

[0300] In this case, when the pilot MP operates the simulator 200, the controller 50 determines and identifies the pilot MP who operates the simulator 200. The controller 50 stores information about the identified pilot MP. Then, the controller 50 causes a display (e.g., the first display 73) of the simulator 200 to display a situation in which the identified pilot MP should train.

[0301] Specifically, for example, it is preferable that the controller 50 presents to the pilot MP, in the simulator 200, at least one of a difficult situation that is a situation that the pilot MP finds difficult to handle and a complacent situation that is a situation that the pilot MP is likely to become complacent. In this case, it is more preferable that the controller 50 presents to the pilot MP a list of the difficult situations and the complacent situation. The difficult situation may be, for example, a situation in which the actual quantitative impatience value is greater than a reference value when the pilot MP operates the simulator 200, and the difference therebetween (quantitative impatience value-reference value) is equal to or greater than a first allowable value. The complacent situation may be, for example, a situation in which the actual quantitative impatience value is smaller than a reference value when the pilot MP operates the simulator 200, and the difference therebetween (quantitative impatience value-reference value) is equal to or less than a second allowable value. In the fourth aspect, each of the difficult situation information and the complacent situation is an example of a task content.

[0302] The controller 50 may, for example, use the work history data of the operator MP stored in the database (for example, time-series data of the operator MP's past psychological states) to list at least one of the difficult situations and the complacent situations. The controller 50 may then display, for example, a list of the one or more difficult situations and the one or more complacent situations on the display of the simulator 200. The past work history data of the operator MP may be work history data when the operator MP operated the simulator 200, or may be work history data when the operator MP operated the construction machine 100.

[0303] The controller 50 controls the operator MP to select from among a plurality of situations (a plurality of work contents) including at least one of the difficult situation and the complacent situation displayed on the display. Specifically, the controller 50 displays a plurality of situations as a plurality of options on the display, and displays the situation to prompt the operator MP to select. When the operator MP selects one of the options, the controller 50 controls the operation of the simulator 200 so that the selected situation (work content) is reproduced. This allows the operator MP to train for the work related to the difficult situation or the complacent situation. When the training is completed, the controller 50 may display the training results on the display. This allows the operator MP to grasp the results of the training, and to utilize the results in the work using the actual construction machine 100.

[0304] In addition, when there is no past work history data of the driver MP, at least one of the difficult situations and the complacent situations may be listed using past work history data of another driver.

[0305] [Variations] Although the first to fourth aspects of the present disclosure have been described above, the present disclosure is not limited to the first to fourth aspects and includes, for example, the following modified examples.

[0306] (A) About the Controller The controller may include a plurality of controller units, in which case the plurality of controller units include a first controller unit and a second controller unit, and the first controller unit may be located in the same location as the second controller unit or may be located in a different location from the second controller unit.

[0307] (B) Mental state In the above explanation of the work support systems 300A, 300B, 300C, 300D relating to the first to fourth aspects, the psychological state has mainly been exemplified as the impatience (degree of impatience) of the operator MP when operating the construction machine 100 or the simulator 200, but the psychological state may also be the fatigue (degree of fatigue) of the operator MP when operating the construction machine 100 or the simulator 200, or the concentration (degree of concentration) of the operator MP when operating the construction machine 100 or the simulator 200.

[0308] (C) Construction machinery In the above description of the embodiment of the first aspect, the construction machine 100 (operation target) is a crawler excavator, but the construction machine according to another embodiment of the first aspect may be a construction machine other than a crawler excavator. For example, when the construction machine is a crane, the content of the work support is determined using the psychological state quantitative value of the operator who operates the crane to lift and move a load slinging on the hook of the crane and the target psychological state set for the crane work. For example, when the construction machine is a bulldozer, the content of the work support is determined using the psychological state quantitative value of the operator who operates the bulldozer to perform ground leveling work using the blade (blade) of the bulldozer and the target psychological state set for the ground leveling work. For example, when the construction machine is a road roller, the content of the work support is determined using the psychological state quantitative value of the operator who operates the road roller to perform compaction work to compact the soil using the rollers of the road roller and the target psychological state set for the compaction work. For example, if the construction machinery is a forklift, the content of the work assistance is determined using the quantitative psychological state value of the operator who operates the forklift to load and transport loads on the forklift's loading and unloading tines, and a target psychological state set for the loading and unloading work.

[0309] In the above description of the embodiment of the second aspect, the construction machine 100 (operation target) is a crawler excavator, but the construction machine according to another embodiment of the second aspect may be a construction machine other than a crawler excavator. For example, when the construction machine is a crane, the content of the work support is determined using the psychological state quantitative value of the operator who operates the crane to lift and move a load slinging on the hook of the crane and the productivity of the crane work. For example, when the construction machine is a bulldozer, the content of the work support is determined using the psychological state quantitative value of the operator who operates the bulldozer to perform ground leveling work using the blade (blade) of the bulldozer and the productivity of the ground leveling work. For example, when the construction machine is a road roller, the content of the work support is determined using the psychological state quantitative value of the operator who operates the road roller to perform compaction work to compact the soil using the roller of the road roller and the productivity of the compaction work. For example, if the construction machine is a forklift, the content of the work assistance is determined using the quantitative psychological state value of the operator who operates the forklift to load and transport cargo onto the forklift's loading and unloading tines, and the productivity of the loading and unloading work.

[0310] In the above description of the embodiment of the third aspect, the construction machine 100 (operation target) is a crawler excavator, but the construction machine according to another embodiment of the third aspect may be a construction machine other than a crawler excavator. For example, if the construction machine is a crane, the change promotion information is transmitted to an operator who operates at least one of the crane and the simulator of the crane to lift and move a load slinging on the hook of the crane in the crane or simulator, and the psychological state is acquired, and the content of the improvement information is determined using data related to the change in the psychological state before and after the transmission of the change promotion information. For example, if the construction machine is a bulldozer, the change promotion information is transmitted to an operator who operates at least one of the bulldozer and the simulator of the bulldozer to perform ground leveling work using the blade (blade) of the bulldozer in the bulldozer or simulator, and the psychological state is acquired, and the content of the improvement information is determined using data related to the change in the psychological state before and after the transmission of the change promotion information. For example, if the construction machine is a road roller, change promotion information is transmitted to an operator who operates at least one of the road roller and a simulator of the road roller to perform compaction work of compacting soil using the rollers of the road roller or the simulator, and the content of the improvement information is determined using data related to changes in the psychological state before and after the transmission of the change promotion information.For example, if the construction machine is a forklift, change promotion information is transmitted to an operator who operates at least one of the forklift and a simulator of the forklift to perform loading and unloading work of loading and transporting loads on the loading and unloading tines of the forklift or the simulator, and the content of the improvement information is determined using data related to changes in the psychological state before and after the transmission of the change promotion information.

[0311] In the above description of the embodiment of the fourth aspect, the construction machine 100 (operation target) is a crawler excavator, but the construction machine according to another embodiment of the fourth aspect may be a construction machine other than a crawler excavator. For example, when the construction machine is a crane, the support content for improving the operator's proficiency in operation is determined using data on the change in the psychological state of the operator who operates at least one of the crane and the simulator of the crane to lift and move a load slinging on the hook of the crane in the crane or simulator and data on the accompanying circumstances. For example, when the construction machine is a bulldozer, the support content for improving the operator's proficiency in operation is determined using data on the change in the psychological state of the operator who operates at least one of the bulldozer and the simulator of the bulldozer to perform ground leveling work using the blade (blade) of the bulldozer in the bulldozer or simulator and data on the accompanying circumstances. For example, if the construction machine is a road roller, the support content for improving the operator's proficiency in operation is determined using data on changes in the psychological state of the operator who operates at least one of the road roller and a simulator of the road roller to compact soil using the rollers of the road roller in the road roller or the simulator and data on accompanying circumstances.For example, if the construction machine is a forklift, the support content for improving the operator's proficiency in operation is determined using data on changes in the psychological state of the operator who operates at least one of the forklift and a simulator of the forklift to load and transport a load on the loading claws of the forklift in the forklift or the simulator and data on accompanying circumstances.

[0312] (D) About the operation target In the above description of the embodiment of the first aspect, the case where the operation target is the construction machine 100 is exemplified, but the operation target according to other embodiments of the first aspect may be an operation target other than a construction machine. For example, when the operation target is an unmanned airplane, the content of the work support is determined so that the psychological state quantitative value of the operator who operates the unmanned airplane and performs work such as photographing and surveying while moving in the air over farmland, disaster sites, etc. with an imaging device mounted on the unmanned airplane approaches the target psychological state. For example, when the operation target is a vehicle such as an automobile or truck, the content of the work support is determined so that the psychological state quantitative value of the operator who operates the vehicle and performs transportation work such as passenger transportation and cargo transportation approaches the target psychological state. For example, when the operation target is an industrial robot, the content of the work support is determined so that the psychological state quantitative value of the operator who operates the industrial robot and performs line work related to manufacturing and assembly approaches the target psychological state. For example, when the operation target is a traffic guidance robot arranged at a road construction site, the content of the work support is determined so that the psychological state quantitative value of the operator who operates the traffic guidance robot to monitor the road construction site and guide passing vehicles and pedestrians approaches the target psychological state. For example, when the operation target is a household robot, the content of the work support is determined so that the psychological state quantitative value of the operator who operates the household robot to perform household tasks such as housework and nursing care approaches the target psychological state. For example, when the operation target is a customer service robot, the content of the work support is determined so that the psychological state quantitative value of the operator who operates the customer service robot to perform customer service tasks such as serving food in a restaurant and guiding customers approaches the target psychological state.

[0313] In the above description of the embodiment of the second aspect, the case where the operation target is the construction machine 100 is exemplified, but the operation target according to other embodiments of the second aspect may be an operation target other than a construction machine. For example, when the operation target is an unmanned airplane, the content of the work support is determined using the psychological state quantitative value of the operator who operates the unmanned airplane and performs work such as photographing and surveying while moving in the air over farmland, disaster sites, etc. with an imaging device mounted on the unmanned airplane, and the productivity of the work. For example, when the operation target is a vehicle such as an automobile or truck, the content of the work support is determined using the psychological state quantitative value of the operator who operates the vehicle to perform transportation work such as passenger transportation and cargo transportation, and the productivity of the transportation work. For example, when the operation target is an industrial robot, the content of the work support is determined using the psychological state quantitative value of the operator who operates the industrial robot to perform line work related to manufacturing and assembly, and the productivity of the line work. For example, if the operation target is a traffic guidance robot to be placed at a road construction site, the content of the work support is determined using the psychological state quantitative value of an operator who operates the traffic guidance robot to monitor the road construction site and guide passing vehicles and pedestrians, and the productivity of the traffic guidance work. For example, if the operation target is a household robot, the content of the work support is determined using the psychological state quantitative value of an operator who operates the household robot to perform household tasks such as housework and nursing care, and the productivity of the household tasks. For example, if the operation target is a customer service robot, the content of the work support is determined using the psychological state quantitative value of an operator who operates the customer service robot to perform customer service tasks such as serving food in a store and guiding customers, and the productivity of the customer service tasks.

[0314] In the above description of the embodiment of the third aspect, the case where the operation target is at least one of the construction machine 100 and the simulator of the construction machine 100 is exemplified, but the operation target according to other embodiments of the third aspect may be an operation target other than the construction machine and the simulator of the construction machine. For example, when the operation target is at least one of the unmanned airplane and the simulator of the unmanned airplane, the change promotion information is transmitted to the operator who operates at least one of the unmanned airplane and the simulator and performs work such as photographing and surveying while moving in the air over farmland, disaster sites, etc., using an imaging device mounted on the unmanned airplane or the simulator, and the content of the improvement information is determined using data regarding changes in the psychological state before and after the transmission of the change promotion information. For example, when the operation target is at least one of the vehicle and the simulator of the vehicle, the change promotion information is transmitted to the operator who operates at least one of the vehicle and the simulator to perform transportation work such as passenger transportation and cargo transportation, and the psychological state is obtained, and the content of the improvement information is determined using data regarding changes in the psychological state before and after the transmission of the change promotion information. For example, when the operation target is at least one of an industrial robot and a simulator of the industrial robot, change promotion information is transmitted to an operator who operates at least one of the industrial robot and the simulator to perform line work related to manufacturing or assembly, and a psychological state is acquired, and the content of the improvement information is determined using data related to the change in the psychological state before and after the transmission of the change promotion information.For example, when the operation target is at least one of a traffic guidance robot arranged at a road construction site and a simulator of the traffic guidance robot, change promotion information is transmitted to an operator who operates at least one of the traffic guidance robot and the simulator to monitor the road construction site and guide passing vehicles and pedestrians, and a psychological state is acquired, and the content of the improvement information is determined using data related to the change in the psychological state before and after the transmission of the change promotion information.For example, when the operation target is at least one of a household robot and a simulator of the household guidance robot, change promotion information is transmitted to an operator who operates at least one of the household robot and the simulator to perform household tasks such as housework and nursing care, and a psychological state is acquired, and the content of the improvement information is determined using data related to the change in the psychological state before and after the transmission of the change promotion information.For example, when the operation target is at least one of a customer service robot and a simulator of the customer service guidance robot, change promotion information is transmitted to an operator who operates at least one of the customer service robot and the simulator to perform customer service tasks such as serving food in a store and guiding customers, and a psychological state is acquired, and the content of the improvement information is determined using data related to the change in the psychological state before and after the transmission of the change promotion information.

[0315] In the above description of the embodiment of the fourth aspect, the case where the operation target is the construction machine 100 is exemplified, but the operation target according to other embodiments of the fourth aspect may be an operation target other than a construction machine.

For example, when the operation target is at least one of a vehicle and a simulator of the vehicle, the support content for improving the operator's proficiency in operation is determined using data on changes in the psychological state of the operator who operates at least one of the vehicle and the simulator and performs transportation work such as passenger transportation and cargo transportation, and data on accompanying circumstances. For example, when the operation target is at least one of an industrial robot and a simulator of the industrial robot, the support content for improving the operator's operation proficiency is determined using data on changes in the psychological state of the operator who operates at least one of the industrial robot and the simulator to perform line work related to manufacturing or assembly and data on accompanying circumstances.For example, when the operation target is at least one of a traffic guidance robot arranged at a road construction site and a simulator of the traffic guidance robot, the support content for improving the operator's operation proficiency is determined using data on changes in the psychological state of the operator who operates at least one of the traffic guidance robot and the simulator to monitor the road construction site and guide passing vehicles and pedestrians and data on accompanying circumstances.For example, when the operation target is at least one of a household robot and a simulator of the household robot, the support content for improving the operator's operation proficiency is determined using data on changes in the psychological state of the operator who operates at least one of the household robot and the simulator to perform household tasks such as housework and nursing care and data on accompanying circumstances.For example, when the operation target is at least one of a customer service robot and a simulator of the customer service robot, the support content for improving the operator's operation proficiency is determined using data on changes in the psychological state of the operator who operates at least one of the customer service robot and the simulator to perform customer service tasks such as serving food in a restaurant and guiding customers and data on accompanying circumstances.
