DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment will be described with reference to the drawings.

[0011] [Overview of the work support system]

[0012] First, an overview of the work support system SYS according to this embodiment will be described with reference to FIG.

[0013] FIG. 1 is a schematic diagram showing an example of a work support system SYS according to this embodiment.

[0014] The work support system SYS includes a shovel 100, a management device 200, and a support terminal 300. The work support system SYS supports the shovel 100 in executing various tasks through the management device 200 and the support terminal 300.

[0015] The work support system SYS may include one or more shovels 100. In other words, the shovel 100 that is the target of work support by the management device 200 and the support terminal 300 may be one or more. Also, the work support system SYS may include one or more management device 200 and support terminal 300.

[0016] Incidentally, a part or all of one or more shovels 100 included in the work support system SYS may be replaced with other work machines. In other words, the above-mentioned reservation function may be applied to any work machine other than the shovel 100, and the management device 200 and the support terminal 300 may be configured to support various works of any work machine instead of or in addition to the shovel 100. The other work machines may include, for example, a lifting magnet machine having a lifting magnet attached as an end attachment, a mobile crane, a bulldozer, a wheel loader, an asphalt finisher, a forestry machine, and the like.

[0017] <Outline of the excavator> An excavator 100 (an example of a work machine) according to this embodiment includes a lower traveling body 1, an upper rotating body 3 mounted on the lower traveling body 1 so as to be rotatable via a rotating mechanism 2, a boom 4, an arm 5, and a bucket 6 constituting an attachment, and a cabin 10. Hereinafter, the front of the excavator 100 corresponds to the extension direction of the attachment relative to the upper rotating body 3 when the excavator 100 is viewed in a plan view from directly above along the rotation axis of the upper rotating body 3 (hereinafter simply referred to as a "plan view"). In addition, the left and right sides of the excavator 100 correspond to the left and right sides, respectively, as viewed from a shovel user in the cabin 10.

[0018] The lower traveling body 1 includes, for example, a pair of left and right crawlers, and the excavator 100 travels when the crawlers are hydraulically driven by traveling hydraulic motors 1L, 1R (see Figs. 2A and 2B).

[0019] The upper rotating body 3 rotates relative to the lower traveling body 1 as a result of the rotating mechanism 2 being hydraulically driven by a rotating hydraulic motor 2A (FIGS. 2A and 2B).

[0020] The boom 4 is pivotally attached to the front center of the upper rotating body 3 so as to be able to tilt up and down, an arm 5 is pivotally attached to the tip of the boom 4 so as to be able to rotate up and down, and a bucket 6 is pivotally attached to the tip of the arm 5 so as to be able to rotate up and down.

[0021] The boom 4, the arm 5, and the bucket 6 are hydraulically driven by a boom cylinder 7, an arm cylinder 8, and a bucket cylinder 9, which serve as hydraulic actuators, respectively.

[0022] The cabin 10 is a control room in which a user of the shovel 100, such as an operator, rides, and is mounted on the left front part of the upper rotating body 3. The shovel user may include, for example, an operator of the shovel 100, a serviceman who performs maintenance or the like on the shovel 100, an owner of the shovel 100, a manager of the shovel 100, and the like.

[0023] Moreover, the shovel 100 according to this embodiment accepts a reservation for a predetermined function of the shovel 100 (hereinafter, "reservation target function") in response to a predetermined input from the shovel user of the shovel 100, and executes the reservation target function in response to conditions specified in the accepted reservation. Hereinafter, the function of the shovel 100 is referred to as a "reservation function." The reservation target function may include, for example, a function of the shovel 100 automatically starting up and warming up (hereinafter, "warming up function") (an example of a predetermined function). The reservation target function may include a function of the shovel 100 automatically executing a predetermined task (hereinafter, "automatic task function") (an example of a predetermined function). The reservation target function may include, for example, a function of the shovel 100 performing self-diagnosis (hereinafter, "self-diagnosis function") (an example of a predetermined function). The reservation target function may include, for example, a function of the shovel 100 restricting the operation (hereinafter, "operation restriction function") (an example of a predetermined function). Details of the reservation function of the shovel 100 will be described later (see Figs. 3 to 6).

[0024] The shovel 100 according to the present embodiment includes a communication device 60 and is communicatively connected to external devices such as the management device 200 through a communication network NW. The communication network NW may include, for example, a wide area network (WAN). The wide area network may include, for example, a mobile communication network with a base station as a terminal. The wide area network may include, for example, a satellite communication network using a communication satellite. The wide area network may include, for example, the Internet network. The wide area network may include, for example, a wired or wireless local area network (LAN). The local network may include, for example, a predetermined short-range communication network such as WiFi or Bluetooth (registered trademark). The shovel 100 receives various signals (for example, information signals, control signals, etc.) from the management device 200 through the communication network NW and transmits various signals to the management device 200, thereby exchanging various signals. As a result, the shovel 100 can receive support for various tasks from the management device 200.

[0025] For example, the shovel 100 receives a command signal for a reservation function (hereinafter, "reservation command signal") from the management device 200. Then, in response to the reservation command signal, the shovel 100 accepts a reservation for the execution of the reserved function specified in the reservation command signal. This allows the shovel 100 to automatically execute the reserved function in response to the reservation from the management device 200, without relying on input such as an operation on the shovel 100 side.

[0026] <Overview of management device> The management device 200 (an example of an information processing device) provides support for various tasks performed by the shovel 100. The management device 200 may be, for example, a cloud server provided in a management center or the like outside the work site of the shovel 100. The management device 200 may also be, for example, an edge server provided in a temporary office in the work site of the shovel 100 or a location relatively close to the work site (for example, a station building or base station). The management device 200 may also be, for example, a stationary terminal device such as a desktop computer terminal provided in a temporary office in the work site of the shovel 100. The management device 200 may also be, for example, a mobile terminal such as a smartphone, a tablet terminal, or a laptop computer terminal.

[0027] The management device 200 is communicably connected to the shovel 100 through the communication network NW. The management device 200 may transmit an information signal or a control signal to the shovel 100 and receive an information signal from the shovel 100 to exchange various signals with the shovel 100. This allows the management device 200 to externally support various operations of the shovel 100 through the exchange of signals with the shovel 100.

[0028] For example, as described above, the management device 200 can transmit a reservation command signal to the shovel 100 and cause the shovel 100 to automatically execute the reserved function according to the conditions specified in the reservation command signal.

[0029] <Summary of Support Device> The support terminal 300 (an example of an information processing device) provides support for various tasks performed by the shovel 100 via the management device 200 based on operations by users (hereinafter referred to as "support terminal users") such as workers or supervisors at the work site where the shovel 100 is used. The support terminal 300 may be, for example, a mobile terminal such as a mobile phone, a smartphone, a tablet terminal, or a laptop computer terminal. The support terminal 300 may also be, for example, a fixed terminal such as a desktop computer terminal installed in a temporary office at the work site.

[0030] The support terminal 300 is communicably connected to the management device 200 through the communication network NW. The support terminal 300 may transmit information signals and control signals to the shovel 100 and obtain information signals from the shovel 100 via the management device 200, for example, to exchange various signals with the shovel 100. This allows the support terminal 300 to externally support various tasks of the shovel 100 through the exchange of signals with the shovel 100.

[0031] For example, the support terminal 300 can transmit a reservation command signal to the shovel 100 via the management device 200 and cause the shovel 100 to automatically execute a specified function according to the conditions specified in the reservation command signal.

[0032] The support terminal 300 may communicate directly with the shovel 100 via the communication network NW.

[0033] [Work support system configuration] Next, a specific configuration of the work support system SYS will be described with reference to FIG. 2 (FIGS. 2A and 2B) in addition to FIG.

[0034] 2A and 2B are block diagrams showing an example and another example of the configuration of the work support system SYS according to this embodiment, respectively. Between Fig. 2A and Fig. 2B, only the configuration of the shovel 100 is different from each other among the shovel 100, the management device 200, and the support terminal 300.

[0035] In the figure, mechanical power lines are indicated by double lines, high pressure hydraulic lines are indicated by solid lines, pilot lines are indicated by dashed lines, and electrical drive and control lines are indicated by dotted lines.

[0036] <Excavator configuration> <<Hydraulic drive system>> As described above, the hydraulic drive system of the excavator 100 according to this embodiment includes hydraulic actuators that hydraulically drive each of the driven elements, such as the lower traveling body 1, the upper rotating body 3, the boom 4, the arm 5, and the bucket 6. As described above, the hydraulic actuators include the traveling hydraulic motors 1L, 1R, the swing hydraulic motor 2A, the boom cylinder 7, the arm cylinder 8, and the bucket cylinder 9. The hydraulic drive system of the excavator 100 according to this embodiment also includes the engine 11, the regulator 13, the main pump 14, and the control valve 17.

[0037] The engine 11 is the main power source in the hydraulic drive system, and is, for example, a diesel engine that uses light oil as fuel. The engine 11 is mounted, for example, at the rear of the upper rotating body 3, and rotates at a constant speed at a preset target speed under direct or indirect control by a controller 30 (described later), to drive the main pump 14 and the pilot pump 15.

[0038] The regulator 13 controls (adjusts) the discharge amount of the main pump 14 under the control of the controller 30. For example, the regulator 13 adjusts the angle of the swash plate of the main pump 14 (hereinafter, the "tilt angle") in response to a control command from the controller 30.

[0039] The main pump 14 is mounted on the rear of the upper rotating body 3, for example, like the engine 11, and supplies hydraulic oil to the control valve 17 through a high-pressure hydraulic line. The main pump 14 is driven by the engine 11 as described above. The main pump 14 is, for example, a variable displacement hydraulic pump, and as described above, under the control of the controller 30, the tilt angle of the swash plate is adjusted by the regulator 13 to adjust the stroke length of the piston, thereby controlling the discharge flow rate (discharge pressure).

[0040] The control valve 17 is, for example, mounted in the center of the upper rotating body 3, and is a hydraulic control device that controls the hydraulic actuators in response to the operation of the operating device 26 by the operator or a control command (hereinafter, "automatic control command") corresponding to the automatic operation of the excavator 100 output from the controller 30. As described above, the control valve 17 is connected to the main pump 14 via a high-pressure hydraulic line, and selectively supplies hydraulic oil supplied from the main pump 14 to the hydraulic actuators (travel hydraulic motors 1L, 1R, swing hydraulic motor 2A, boom cylinder 7, arm cylinder 8, bucket cylinder 9, etc.) in response to the operating state of the operating device 26 or an automatic control command output from the controller 30. Specifically, the control valve 17 includes a plurality of control valves (also referred to as directional control valves) that control the flow rate and flow direction of the hydraulic oil supplied from the main pump 14 to each of the hydraulic actuators.

[0041] <<Operation system>> The operating system for the hydraulic drive system of the shovel 100 according to this embodiment includes the pilot pump 15 and the operating device 26. Furthermore, as shown in Fig. 2A, the operating system for the hydraulic drive system of the shovel 100 includes a shuttle valve 32 when the operating device 26 is of a hydraulic pilot type.

[0042] The pilot pump 15 is mounted on the rear of the upper rotating body 3, similar to the engine 11, and supplies pilot pressure to various hydraulic devices via a pilot line 25. The pilot pump 15 is, for example, a fixed displacement hydraulic pump, and is driven by the engine 11 as described above.

[0043] The operation device 26 is provided near the cockpit inside the cabin 10, and is an operation input means for the operator to operate various driven elements (lower traveling body 1, upper rotating body 3, boom 4, arm 5, bucket 6, etc.). In other words, the operation device 26 is an operation input means for the operator to operate hydraulic actuators (i.e., traveling hydraulic motors 1L, 1R, swing hydraulic motor 2A, boom cylinder 7, arm cylinder 8, bucket cylinder 9, etc.) that drive the respective driven elements. The operation device 26 includes, for example, a lever device that operates each of the boom 4 (boom cylinder 7), arm 5 (arm cylinder 8), bucket 6 (bucket cylinder 9), and upper rotating body 3 (swing hydraulic motor 2A). The operation device 26 also includes, for example, a pedal device or lever device that operates each of the left and right crawlers (traveling hydraulic motors 1L, 1R) of the lower traveling body 1.

[0044] For example, as shown in Fig. 2A, the operating device 26 is of a hydraulic pilot type. Specifically, the operating device 26 uses hydraulic oil supplied from the pilot pump 15 through a pilot line 25 and a pilot line 25A branched from the pilot line 25 to output a pilot pressure corresponding to the operation content to a pilot line 27 on the secondary side. The pilot line 27 is connected to the control valve 17 via a shuttle valve 32. As a result, pilot pressure corresponding to the operation content related to various driven elements (hydraulic actuators) in the operating device 26 can be input to the control valve 17 via the shuttle valve 32. Therefore, the control valve 17 can drive each hydraulic actuator according to the operation content of the operating device 26 by an operator or the like.

[0045] 2B, the operating device 26 is of an electrical type. Specifically, the operating device 26 outputs an electrical signal corresponding to the operation content, and the electrical signal is input to the controller 30. The controller 30 then outputs a control command (hereinafter, distinguished from an automatic control command, and referred to as an "operation control command") corresponding to the content of the electrical signal, that is, the operation content on the operating device 26, to the proportional valve 31. As a result, a pilot pressure corresponding to the operation content on the operating device 26 is input from the proportional valve 31 to the control valve 17, and the control valve 17 can drive each hydraulic actuator according to the operation content on the operating device 26 by an operator or the like.

[0046] Furthermore, if the control valve (directional control valve) built into the control valve 17 is of an electromagnetic solenoid type, the electrical signal output from the operating device 26 may be directly input to the control valve 17, that is, the electromagnetic solenoid type control valve.

[0047] As shown in FIG. 2A, the shuttle valve 32 has two inlet ports and one outlet port, and outputs hydraulic oil having a higher pilot pressure of the two pilot pressures input to the two inlet ports to the outlet port. The shuttle valve 32 is provided for each driven element (left and right crawlers, upper rotating body 3, boom 4, arm 5, bucket 6, etc.) that is the object of operation of the operation device 26. One of the two inlet ports of the shuttle valve 32 is connected to the operation device 26 (specifically, the above-mentioned lever device or pedal device included in the operation device 26), and the other is connected to the proportional valve 31. The outlet port of the shuttle valve 32 is connected through a pilot line to the pilot port of the corresponding control valve of the control valve 17 (specifically, the control valve corresponding to the hydraulic actuator that is the object of operation of the above-mentioned lever device or pedal device connected to one inlet port of the shuttle valve 32). Therefore, each of these shuttle valves 32 can apply the higher of the pilot pressure generated by the operation device 26 and the pilot pressure generated by the proportional valve 31 to the pilot port of the corresponding control valve. That is, the controller 30 described later can control the corresponding control valve, regardless of the operation of the operation device 26 by the operator, by causing the proportional valve 31 to output a pilot pressure higher than the secondary pilot pressure output from the operation device 26. Therefore, the controller 30 can automatically control the operation of the driven elements (the lower traveling body 1, the upper rotating body 3, and the attachment) regardless of the operation state of the operation device 26 by the operator.

[0048] <<Control system>> The control system of the shovel 100 according to this embodiment includes a controller 30, a calculation device 30E, a proportional valve 31, a surrounding information acquisition device 40, a self-machine information acquisition device 42, a display device 50, an input device 52, and a communication device 60. Furthermore, as shown in Fig. 2A, the control system of the shovel 100 according to this embodiment includes an operating pressure sensor 29 when the operating device 26 is of a hydraulic pilot type.

[0049] The controller 30 performs various controls related to the excavator 100. The functions of the controller 30 may be realized by any hardware or any combination of hardware and software. For example, the controller 30 is mainly configured with a microcomputer including a central processing unit (CPU), a memory device such as a random access memory (RAM), a non-volatile auxiliary storage device such as a read only memory (ROM), and an interface device. The same applies to the control devices 210 and 310 described below. The controller 30 includes a reservation target function unit 301, a reservation screen display processing unit 302, a reservation acceptance unit 303, and a reservation execution unit 305 as functional units realized by executing one or more programs installed in the auxiliary storage device on the CPU. The controller 30 also uses a reservation information storage unit 304, etc. The reservation information storage unit 304 is realized by, for example, an auxiliary storage device or an external storage device connected in a communicable manner.

[0050] Specifically, the controller 30 may control the proportional valve 31 (specifically, output an automatic control command to the proportional valve 31) based on the calculation results of the calculation device 30E, specifically, based on a drive command for the hydraulic actuator, and operate the shovel 100 regardless of the operation of the operator.

[0051] Note that some of the functions of the controller 30 may be realized by another controller (control device). That is, the functions of the controller 30 may be realized in a distributed manner by a plurality of controllers.

[0052] The arithmetic device 30E performs arithmetic processing related to various functions of the controller 30 under the control of the controller 30. The arithmetic device 30E may be realized by any hardware or any combination of hardware and software. For example, the arithmetic device 30E includes a GPU (Graphical Processing Unit), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-programmable gate array), etc., and realizes high-speed arithmetic processing.

[0053] Specifically, the arithmetic device 30E may recognize the surrounding conditions of the shovel 100 (the shovel itself) based on the output information of the surrounding information acquisition device 40. For example, the arithmetic device 30E may recognize objects around the shovel itself and the distance to those objects. The arithmetic device 30E may also recognize the position and attitude of the shovel itself (e.g., the attitude of the attachment, the attitude of the upper rotating body 3, etc.) based on the output information of the own-machine information acquisition device 42. Then, the arithmetic device 30E may calculate and generate a drive command for a hydraulic actuator for automatically operating the shovel 100 based on the recognized surrounding conditions of the shovel 100 and various states of the shovel 100.

[0054] The arithmetic device 30E can also recognize the position of the shovel 100 (own machine) and the attitude state (e.g., tilt state and rotation state) of the upper rotating body 3 based on changes in the positions of objects around the shovel 100 (own machine) recognized based on the output information of the surrounding information acquisition device 40. Furthermore, when the arithmetic device 30E can recognize the attachment of the shovel 100 and its position from the output information of the surrounding information acquisition device 40, it can also recognize the attitude state of the attachment based on the output information of the surrounding information acquisition device 40. Therefore, if other conditions (e.g., recognition accuracy, etc.) are met, the own machine information acquisition device 42 may be omitted.

[0055] The proportional valve 31 is provided for each driven element (left and right crawlers, upper rotating body 3, boom 4, arm 5, and bucket 6) to be operated by the operating device 26. The proportional valve 31 is provided in the pilot line 25 (pilot line 25B branching from the pilot line 25 in the case of FIG. 2A) between the pilot pump 15 and the control valve 17, and is configured to be able to change its flow passage area (i.e., a cross-sectional area through which hydraulic oil can flow). This allows the proportional valve 31 to output a predetermined pilot pressure to the secondary side by using the hydraulic oil of the pilot pump 15 supplied through the pilot line 25 (pilot line 25B). Therefore, the proportional valve 31 can apply a predetermined pilot pressure to the control valve 17 according to a control command from the controller 30 via the shuttle valve 32 as shown in FIG. 2A, or directly as shown in FIG. 2B. In other words, the controller 30 outputs an operation control command corresponding to an electric signal from the electric operating device 26 to the proportional valve 31, thereby causing the proportional valve 31 to supply a pilot pressure corresponding to the operation of the operating device 26 to the control valve 17, thereby realizing the operation of the shovel 100 based on the operation of the operator. Furthermore, even if the operating device 26 is not operated by the operator, the controller 30 outputs an automatic control command to the proportional valve 31, thereby causing the proportional valve 31 to supply a predetermined pilot pressure to the control valve 17, thereby realizing the automation of the shovel 100.

[0056] The surrounding information acquisition device 40 outputs information on the situation of the three-dimensional space around the shovel 100 (specifically, detection information on objects around the shovel 100 and their positions). The surrounding information acquisition device 40 may include, for example, an ultrasonic sensor, a millimeter wave radar, a monocular camera, a stereo camera, a depth camera, a LIDAR (Light Detection and Ranging), a distance image sensor, an infrared sensor, and the like. In this embodiment, the surrounding information acquisition device 40 includes a forward sensor 40F attached to the front end of the upper surface of the cabin 10, a rear sensor 40B attached to the rear end of the upper surface of the upper rotating body 3, a left sensor 40L attached to the left end of the upper surface of the upper rotating body 3, and a right sensor 40R attached to the right end of the upper surface of the upper rotating body 3. In addition, an upper sensor that outputs information on the situation of the three-dimensional space above the upper rotating body 3 (for example, detection information on objects present above the upper rotating body 3) may be attached to the shovel 100. Further, some or all of the rear sensor 40B, the left sensor 40L, the right sensor 40R, and the upper sensor may be omitted depending on the performance required for the automatic operation of the shovel 100. The output information of the surrounding information acquisition device 40 is input to the calculation device 30E.

[0057] The machine information acquisition device 42 acquires information on various states of the shovel 100 (machine itself) (e.g., the state of the position, orientation, attitude, etc. of the shovel 100). For example, the machine information acquisition device 42 may include a positioning device (e.g., a Global Navigation Satellite System (GNSS) module, etc.) that acquires information on the position of the machine itself. The machine information acquisition device 42 may also include an attitude sensor that acquires information on the attitude state of each of the boom 4, arm 5, and bucket 6 of the attachment (e.g., attitude angle around the rotation axis), and an attitude sensor that detects the attitude state of the upper rotating body 3 (e.g., tilt angle and rotation angle). In this case, the attitude sensor may include, for example, a rotary encoder, an acceleration sensor, an angular acceleration sensor, a six-axis sensor, an IMU (Inertial Measurement Unit), etc. The attitude sensor related to the attachment may also include a cylinder sensor that detects the cylinder positions of the boom cylinder 7, the arm cylinder 8, the bucket cylinder 9, etc. The output information of the machine information acquisition device 42 is taken into the calculation device 30E.

[0058] The display device 50 is provided at a location that is easily visible to an operator seated in the cabin 10, and displays various information images. The display device 50 is, for example, a liquid crystal display or an organic EL (Electroluminescence) display.

[0059] The input device 52 is provided in the cabin 10 and accepts input from a shovel user such as an operator. The input device 52 includes, for example, an operation input device that is provided within reach of an operator seated in the cabin 10 and accepts various operation inputs by the operator. For example, the operation input device includes hardware operation input means such as a touch panel mounted on the display of the display device 50, a touch pad installed around the display device 50, a button switch, a lever, a toggle, and a knob switch provided on the operation device 26. The operation input device may also include software operation input means operable by hardware operation input means such as a virtual operation object (e.g., an operation icon) displayed on various operation screens displayed on the display device 50. The input device 52 may also include, for example, a voice input device that accepts voice input from a shovel user and a gesture input device that accepts gesture input from a shovel user. The voice input device includes, for example, a microphone that acquires the voice of the shovel user. The gesture input device includes, for example, an indoor camera that captures gestures made by the shovel user. A signal corresponding to the content of the input to the input device 52 is received by the controller 30 .

[0060] The communication device 60 is connected to a predetermined communication network that may include, for example, a mobile communication network terminated in a base station, a satellite communication network using a communication satellite, the Internet, etc., and communicates with an external device (for example, a management device 200 described later) of the shovel 100. rd Generation), 4G(4 th Generation), LTE (Long Term Evolution), 5G (5 th The mobile communication module may be a mobile communication module that complies with a predetermined mobile communication standard such as IEEE 802.11 Generation.

[0061] 2A , the operating pressure sensor 29 detects the pilot pressure on the secondary side (pilot line 27) of the operating device 26, i.e., the pilot pressure corresponding to the operating state of each driven element (hydraulic actuator) in the operating device 26. A detection signal of the pilot pressure by the operating pressure sensor 29, which corresponds to the operating state of the lower traveling body 1, the upper rotating body 3, the boom 4, the arm 5, the bucket 6, etc. in the operating device 26, is input to the controller 30.

[0062] The reservation target function unit 301 executes the reservation target function.

[0063] The reservation target function unit 301 may include, for example, a warm-up operation function unit that executes a warm-up operation function. The warm-up operation function unit may perform a warm-up operation of the shovel 100 by automatically switching the key switch of the shovel 100 from OFF to ON and rotating the engine 11 at a constant speed of a predetermined idling speed.

[0064] Furthermore, the reservation target function unit 301 may include, for example, an automatic work function unit that executes an automatic work function. The automatic work function unit controls the proportional valve 31 (specifically, outputs an automatic control command to the proportional valve 31) based on the calculation result of the calculation device 30E, specifically, based on a drive command for the hydraulic actuator, and automatically operates the shovel 100 without depending on the operation of an operator. In other words, the automatic work function unit may realize the automatic work of the shovel 100 by outputting an automatic control command to the proportional valve 31 and automatically operating the hydraulic actuator.

[0065] The reservation target function unit 301 may include, for example, a self-diagnosis function unit that executes a self-diagnosis function. The self-diagnosis function unit may diagnose the presence or absence of abnormalities, failures, etc. in various devices of the shovel 100 (for example, the engine 11 including the intake system and exhaust system, various hydraulic devices such as the control valve 17, various control devices such as the controller 30, various communication devices such as the communication device 60, various sensors, various actuators, various display devices such as the display device 50 and warning lights, etc.) according to a known self-diagnosis algorithm.

[0066] Furthermore, the reservation target function unit 301 may include, for example, an operation restriction function unit that executes an operation restriction function. The operation restriction function unit restricts various operations of the own machine. For example, the operation restriction function unit may execute a function (hereinafter, "operation time restriction function") that restricts the time period during which the operation (operation) of the shovel 100 is permitted (hereinafter, "operation permitted time period"). In other words, the operation restriction function unit may prohibit the start of the shovel 100 outside the operation permitted time period, and may forcibly stop the shovel 100 that is operating outside the operation permitted time period. Furthermore, when the shovel 100 (own machine) is operating outside the operation permitted time period, the operation restriction function unit may automatically move the shovel 100 to a predetermined location (for example, a parking place specified in advance in a work site) and then stop the shovel 100. Furthermore, when the shovel 100 (own machine) is operating outside the permitted operating time period, the operation limiting function unit may issue a notification to the shovel user through a predetermined notification means (e.g., the display device 50 or a speaker in the cabin 10, etc.) to urge the shovel user to move to a predetermined location (e.g., the above-mentioned parking location). In this case, the operation limiting function unit may forcibly stop the shovel 100 after the shovel has moved to the predetermined location. Furthermore, for example, the operation limiting function unit may execute a function (hereinafter, "output limiting function") of controlling the engine 11 or hydraulic actuators of the shovel 100 to limit the operation of the own machine so that the output of the shovel 100 (e.g., digging force during digging work, etc.) is relatively low. Specifically, in the case where a plurality of selectable operating modes (e.g., a first mode prioritizing work efficiency, a second mode achieving both work efficiency and fuel efficiency, and a third mode prioritizing fuel efficiency) are defined in the excavator 100, the operation restriction function unit may limit the availability of only some of the operating modes with relatively low output (e.g., the second mode and the third mode). Also, for example, the operation restriction function unit may execute a function (hereinafter, "air conditioning restriction function") that limits the cooling setting temperature of an air conditioning device mounted in the cabin 10 (an example of a driver's compartment).

[0067] The reservation screen display processing unit 302 causes the display device 50 to display an operation screen for accepting reservations for the reservation target functions of the shovel 100 (hereinafter, the "reservation acceptance screen") and an operation screen for confirming the contents of the accepted reservation (hereinafter, the "reservation confirmation screen"). Hereinafter, the reservation acceptance screen, reservation confirmation screen, and screens related to the reservation function such as the shovel / operator selection screen described below are collectively referred to as "reservation screens." The operator can make reservations for the reservation target functions and confirm the contents of accepted reservations by performing predetermined operations on the reservation screen through the input device 52.

[0068] The reservation reception unit 303 receives a reservation for a reservation target function of the shovel 100 (own machine) in response to an operation of an operator on the reservation reception screen of the display device 50 using the input device 52. The reservation reception unit 303 also receives a reservation for a reservation target function in response to a reservation command signal received from the management device 200 via the communication device 60. The contents of a reservation received by the reservation reception unit 303 include a type of reservation target function to be executed in response to the accepted reservation and a condition for executing the target function (hereinafter, "execution condition"). The execution condition may include a time-related condition (hereinafter, "time condition") that may include a date, a day of the week, a period, and the like, a condition for the operation status of the shovel 100 (own machine) (hereinafter, "operation status condition"), a condition for the environment around the shovel 100 (hereinafter, "environmental condition"), and the like. The execution condition may also include a condition for the operator's attendance status (for example, whether or not an operator who is scheduled to operate the shovel 100 is late or has taken leave due to poor physical condition such as a cold), and the like. In this case, the information regarding the attendance status may be received from the management device 200 via, for example, the communication device 60. Information regarding the contents of the reservation accepted by the reservation acceptance unit 303 (hereinafter, “reservation information”) 304A is registered (stored) in the reservation information storage unit 304.

[0069] Reservation information 304A is stored in the reservation information storage unit 304. For example, the reservation information storage unit 304 may accumulate records including identification information (hereinafter, "reservation identification information") (e.g., a unique reservation ID (identifier) ​​assigned to each reservation, etc.) specified for each reservation accepted by the reservation accepting unit 303, and reservation information 304A (type of function to be reserved, execution conditions, etc.) corresponding to the reservation identification information, thereby constructing a record group of reservation information 304A, that is, a database.

[0070] Furthermore, the reservation information 304A registered in the reservation information storage unit 304 may be uploaded to the management device 200 automatically or in response to a request from the management device 200. This allows an operator or manager of the management device 200 and a user of the support terminal 300 communicably connected to the management device 200 to grasp (confirm) the reservation information registered in the reservation information storage unit 304.

[0071] The reservation execution unit 305 automatically executes a reserved function specified in the reservation information 304A according to the execution conditions specified in the reservation information 304A for each piece of reservation information 304A registered in the reservation information storage unit 304. Specifically, the reservation execution unit 305 starts up the reserved function unit 301 corresponding to the reserved function specified in the reservation information 304A according to the execution conditions specified in the reservation information 304A, and executes the reserved function.

[0072] <Configuration of management device> The management device 200 includes a control device 210 , a communication device 220 , a display device 230 , and an input device 240 .

[0073] The control device 210 performs various controls related to the management device 200. The control device 210 includes, for example, a reservation screen display processing unit 211 and a reservation receiving unit 212 as functional units realized by executing one or more programs installed in an auxiliary storage device on a CPU.

[0074] The communication device 220 is connected to the communication network NW, and communicates with external devices such as the excavator 100 and the support terminal 300 through the communication network NW.

[0075] The display device 230, under the control of the control device 210, displays various information images and a GUI (Graphical User Interface).

[0076] The input device 240 accepts input from a user (hereinafter, "management device user") such as an administrator or an operator of the management device 200, and outputs the input to the control device 210. The input device 240 includes, for example, an operation input device that accepts operation input from the management device user. The operation input device may include, for example, a touch panel, a keyboard, a mouse, etc., implemented on the display device 230. The input device 240 may also include, for example, a voice input device or a gesture input device that accepts voice input or gesture input from the management device user.

[0077] The reservation screen display processing unit 211 causes the display device 230 to display an operation screen for accepting reservations related to the reservation target functions of the shovel 100, i.e., a reservation acceptance screen, and an operation screen for confirming the contents of accepted reservations, i.e., a reservation confirmation screen. The reservation screen display processing unit 211 can display the reservation confirmation screen based on registered reservation information that is uploaded periodically from the shovel 100 or uploaded from the shovel 100 based on a request from the management device 200 (control device 210), for example. Furthermore, when the work support system SYS includes multiple shovels 100, a reservation acceptance screen or a reservation confirmation screen may be displayed for each shovel 100 or for each operator riding on the shovel 100. In this case, the reservation screen display processing unit 211 may display an operation screen (hereinafter, "shovel / operator selection screen") for selecting a target shovel 100 and operator (specifically, the shovel 100 on which the target operator is riding) from a plurality of shovels 100 and a plurality of operators registered in advance, as a preliminary step to displaying the reservation reception screen or the reservation confirmation screen on the display device 230.

[0078] The reservation reception unit 212 accepts a reservation for a reservation target function of the shovel 100 in response to an operation of the management device user on the reservation reception screen of the display device 230 using the input device 240. The reservation reception unit 212 also accepts a reservation for a reservation target function of the shovel 100 in response to a reservation request signal received from the support terminal 300 via the communication device 220. When the reservation reception unit 212 accepts a reservation, it transmits a reservation command signal including the contents of the accepted reservation (e.g., the reservation target function and execution conditions, etc.) to the shovel 100 via the communication device 220. As a result, the reservation contents (reservation information 304A) are registered in the shovel 100 to which the signal is sent. In other words, an administrator user such as an administrator of the management device 200 can make a reservation for the execution of the reservation target function of the shovel 100 from outside the shovel 100.

[0079] <Support device configuration> The support terminal 300 includes a control device 310 , a communication device 320 , a display device 330 , and an input device 340 .

[0080] The control device 310 performs various controls related to the support terminal 300. The control device 310 includes, for example, a reservation screen display processing unit 311 and a reservation reception unit 312 as functional units realized by executing one or more programs installed in an auxiliary storage device on a CPU.

[0081] The communication device 320 is connected to the communication network NW and communicates with external devices such as the management device 200 through the communication network NW.

[0082] The display device 330, under the control of the control device 310, displays various information images and GUIs.

[0083] The input device 340 accepts input from the support terminal user and outputs it to the control device 310. The input device 340 may include, for example, an operation input device that accepts operation input from the support terminal user. The operation input device may be, for example, a touch panel mounted on the display device 330. The input device 340 may also include, for example, a voice input device or a gesture input device that accepts voice input or gesture input from the support terminal user.

[0084] The reservation screen display processing unit 311 causes the display device 330 to display an operation screen for accepting reservations for the reservation target functions of the shovel 100, that is, a reservation acceptance screen, and an operation screen for confirming the contents of accepted reservations, that is, a reservation confirmation screen. The reservation screen display processing unit 311 can display the reservation confirmation screen based on registered reservation information that is periodically downloaded from the management device 200, or that is downloaded from the management device 200 based on a request from the support terminal 300 (control device 310). In addition, when the work support system SYS includes multiple shovels 100, a reservation acceptance screen or a reservation confirmation screen may be displayed for each shovel 100 or for each operator riding on the shovel 100, as in the case of the management device 200 (reservation screen display processing unit 211). In this case, the reservation screen display processing unit 311 may display a shovel / operator selection screen as a preliminary step for displaying the reservation acceptance screen or the reservation confirmation screen on the display device 330.

[0085] The reservation reception unit 312 receives a reservation for a reservation target function of the shovel 100 in response to a user's operation on the reservation reception screen of the display device 330 using the input device 340. When the reservation reception unit 312 receives a reservation, it transmits a reservation request signal including the contents of the received reservation (e.g., the target function and execution conditions, etc.) to the management device 200 via the communication device 320. As a result, a reservation command signal corresponding to the reservation request signal is transmitted to the shovel 100 via the management device 200, and the reservation contents (reservation information 304A) are registered in the shovel 100 as the transmission destination. In other words, the user of the support terminal 300 can make a reservation for the execution of the reservation target function of the shovel 100 from outside the shovel 100.

[0086] [Details on the excavator reservation function] Next, the reservation function of the shovel 100 will be described in detail with reference to Figs. 3 to 7.

[0087] <First example of the reservation function (warm-up operation reservation function)> First, with reference to FIG. 3, a reservation function for executing the warm-up operation function of the excavator 100 (hereinafter, "warm-up operation reservation function") will be described.

[0088] 3 is a diagram for explaining a first example (warm-up operation reservation function) of the reservation function of the shovel 100. Specifically, it is a diagram showing the operating states (stopped, warm-up operation, and normal operation) of the shovel 100 on both weekdays (specifically, Monday to Friday other than holidays) and holidays (specifically, holidays from Monday to Friday) and the execution conditions (date and time conditions) of the warm-up operation reservation function.

[0089] In this example, on weekdays, under the control of the controller 30 (the reservation execution unit 305 and the reservation target function unit 301), the shovel 100 automatically starts up and warms up 10 minutes before 8:00, which is the start time of work in the morning at the work site, that is, at 7:50. Also, on weekdays, under the control of the controller 30, the shovel 100 automatically starts up and warms up 10 minutes before 13:00, which is the start time of work in the afternoon at the work site, that is, at 12:50. Also, on holidays, under the control of the controller 30, the shovel 100 automatically starts up and warms up 10 minutes before 9:00, which is the start time of work in the morning at the work site, that is, at 8:50. Also, on holidays, under the control of the controller 30, the shovel 100 automatically starts up and warms up 10 minutes before 13:00, which is the start time of work in the afternoon at the work site, that is, at 12:50.

[0090] In this example, the execution conditions of the warm-up operation reservation function may be specified by time conditions including a day of the week condition (Monday to Friday), a condition of whether it is a holiday or not, and a start time condition of the shovel 100 (7:50, 8:50, or 12:50). Also, instead of the start time condition of the shovel 100, a work start time condition (8:00, 9:00, or 13:00) and a warm-up operation time (10 minutes) may be adopted. Also, the execution conditions of the warm-up operation reservation function may include an environmental condition, for example, such as "the outside air temperature is equal to or lower than a predetermined temperature." In this case, the outside air temperature of the shovel 100 may be acquired by an outside air temperature sensor mounted on the shovel 100 (for example, the upper rotating body 3).

[0091] The warm-up operation time may be determined appropriately depending on the specifications of the excavator 100, the season, etc.

[0092] When the execution condition (date and time condition) specified in the reservation information 304A is satisfied, the reservation execution unit 305 starts the reservation target function unit 301 (warm-up operation function unit). Then, the reservation target function unit 301 (warm-up operation function unit) automatically shifts the key switch of the shovel 100 from OFF to ON, automatically starts the shovel 100, and maintains the rotation speed of the engine 11 at an idling rotation speed to perform a warm-up operation of the shovel 100.

[0093] A shovel user such as an operator of the shovel 100 or a manager of a work site uses the input device 52 to specify the execution conditions on the reservation reception screen of the display device 50 and confirm the reservation contents. This allows the shovel user such as the operator of the shovel 100 or the manager of a work site to automatically start the shovel 100 and warm up the shovel 100 in accordance with the time conditions without having to go to the shovel 100 and turn on the key switch. Also, a management device user such as a manager of the management device 200 or a support terminal user uses the input devices 240 and 340 to specify the execution conditions on the reservation reception screen displayed on the display devices 230 and 330 and confirm the reservation contents. This allows the management device user such as a manager of the management device 200 or a support terminal user to automatically start the shovel 100 in accordance with the time conditions and warm up the shovel 100 in accordance with the time conditions without having to have someone at the work site go to the shovel 100 and turn on the key switch. Therefore, there is no need for someone to go to the shovel 100 and turn on the key switch before starting work, and the convenience of the operator of the shovel 100, the manager of the work site, and the like can be improved. Furthermore, even without turning on the key switch of the shovel 100 in advance, the warm-up operation of the shovel 100 is completed before work starts, so work using the shovel 100 can be started immediately, and the work efficiency of the shovel 100 can be improved. Furthermore, the manager of the work site, the manager of the management device 200, and the like do not need to keep track of the startup and warm-up operation status of the shovel 100 when starting work at the work site, and the efficiency of operating the shovel 100 can be improved.

[0094] <Second example of reservation function (automatic work reservation function)> Next, a reservation function for executing the automatic work functions of the shovel 100 (hereinafter, "automatic work reservation function") will be described with reference to FIG.

[0095] 4 is a diagram for explaining a second example (automatic work reservation function) of the reservation function of the shovel 100. Specifically, it is a diagram showing a work schedule of the shovel 100 on a specified date (a specified day or one day of a specified number of days or period) and execution conditions (date and time conditions) for the automatic work reservation function.

[0096] In this example, on a specified date, under the control of the controller 30 (the reservation execution unit 305 and the reservation target function unit 301), the shovel 100 automatically performs excavation work on a predetermined work area for two hours from 8:00 to 10:00, which is the work start time at the work site. At this time, if the shovel 100 is stopped at 8:00, the shovel 100 may be automatically started under the control of the controller 30. The same applies below to the case where the shovel 100 is stopped at 13:00. Moreover, under the control of the controller 30, the shovel 100 automatically performs backfilling work on the same work area for two hours from 10:00 to 12:00. At this time, the backfilling work may include work to bury a predetermined buried object. Moreover, under the control of the controller 30, the shovel 100 performs shaping work on the same work area (work to return the work area backfilled by compaction or the like to the flat state before excavation) for four hours from 13:00 to 17:00. At this time, the shovel 100 may automatically stop under the control of the controller 30 at 17:00. Furthermore, the shovel 100 may move to a predetermined location (for example, the above-mentioned parking area) under the control of the controller 30 (reservation execution unit 305) before automatically stopping. Furthermore, the shovel 100 may issue a notification urging the user to move to a predetermined location (for example, the above-mentioned parking area) through a predetermined notification means (for example, the display device 50 or a speaker in the cabin 10, etc.) before automatically stopping.

[0097] In this example, the execution conditions of the automatic work reservation function may be specified by time conditions including a date condition, a start time condition (8:00, 10:00, or 13:00), and an end time condition (10:00, 13:00, or 17:00) for each target automatic work (excavation work, backfilling work, and shaping work). Moreover, instead of the end time condition, the work time from the start time (2 hours or 4 hours) may be adopted. Moreover, when the previous automatic work is finished, the next automatic work may be started. In this case, the execution conditions of the automatic work reservation function may include an operating status condition (for example, "the shovel 100 has completed the excavation work to form a predefined target construction surface (a trench, a hole, or the like) and has stopped the excavation work") and an environmental condition (for example, "the formation of a predefined target construction surface in the work area around the shovel 100 has been completed") instead of or in addition to the date and time condition. Moreover, if the automatic work has not finished even when the end time has come, the automatic work may be continued until it is finished. In this case, the execution conditions for the automatic work reservation function, i.e., the execution conditions for continuing the automatic work, may include an AND condition of a date and time condition and an operating status condition (for example, "the scheduled work has not been completed even when the scheduled end time has arrived").

[0098] The reservation execution unit 305 starts the reservation target function unit 301 (automatic work function unit) when the execution condition (date and time condition) specified in the reservation information 304A is satisfied for each of the multiple target works. Then, the reservation target function unit 301 (automatic work function unit) controls the proportional valve 31 in response to a command from the reservation execution unit 305, and causes the excavator 100 to automatically execute the target work related to a predetermined work area.

[0099] A shovel user such as an operator of the shovel 100 or a manager of a work site uses the input device 52 to specify the execution conditions for each of a plurality of tasks on the reservation reception screen of the display device 50 and confirm the reservation contents. This allows a shovel user such as an operator of the shovel 100 or a manager of a work site to have the shovel 100 automatically perform a plurality of tasks in sequence without going to the shovel 100 to start the automatic work. Also, a management device user such as a manager of the management device 200 or a support terminal user uses the input devices 240, 340 to specify the execution conditions on the reservation reception screen displayed on the display devices 230, 330 and confirm the reservation contents. This allows a management device user such as a manager of the management device 200 or a support terminal user to have the shovel 100 automatically perform a plurality of tasks in sequence without having to have someone at the work site go to the shovel 100 to start the automatic work. Furthermore, there is no need for someone to go to the shovel 100 and perform the operation to start the automatic work at the start of each target task, which improves the convenience of the operator of the shovel 100, the manager of the work site, etc. Furthermore, since the waiting time between one task and the next task can be eliminated, the work efficiency of the shovel 100 can be improved. Furthermore, there is no need for the manager of the work site or the manager of the management device 200, etc. to grasp the status of the automatic work of the shovel 100 every time, which improves the efficiency of the operation of the shovel 100.

[0100] <Third example of reservation function (self-diagnosis reservation function)> Next, a reservation function for executing a self-diagnosis function of the shovel 100 (hereinafter, "self-diagnosis reservation function") will be described with reference to FIG.

[0101] 5 is a diagram for explaining a third example (self-diagnosis reservation function) of the reservation function of the shovel 100. Specifically, it is a diagram showing the operating state (stop, simple diagnosis, and comprehensive diagnosis) of the self-diagnosis function on both working days (for example, Monday to Friday) and non-working days (for example, Saturday and Sunday) of the shovel 100, and the execution conditions of the self-diagnosis reservation function.

[0102] In this example, on an operating day, the shovel 100, under the control of the controller 30 (the reservation executor 305 and the reservation target function unit 301), performs a simple self-diagnosis (hereinafter, "simple diagnosis") for one hour from 17:00 to 18:00, which is the end time of work at the work site. The simple diagnosis may be, for example, a self-diagnosis targeting a major part of the multiple diagnosis items, a self-diagnosis targeting a major part of the multiple devices, or a self-diagnosis that covers both. Also, on a non-operating day, the shovel 100, under the control of the controller 30, performs a comprehensive self-diagnosis (hereinafter, "comprehensive diagnosis") between 10:00 and 12:00. The comprehensive diagnosis is, for example, a self-diagnosis targeting all of the multiple target devices and multiple diagnosis items.

[0103] The time required for self-diagnosis (simple diagnosis or comprehensive diagnosis) (1 hour or 2 hours) is a guideline and may be shorter or longer.

[0104] In this example, the execution conditions for the self-diagnosis reservation function can be specified by a time condition including a day of the week condition (Monday to Friday, or Saturday and Sunday) and a start time condition for the self-diagnosis function. Furthermore, when a self-diagnosis (simple diagnosis) is performed after work is completed on a working day, the execution conditions for the self-diagnosis reservation function may include an operating status condition (for example, "the key switch of the shovel 100 has been shifted from ON to OFF and the shovel 100 has stopped") instead of or in addition to the time condition.

[0105] When the execution condition (time condition) specified in the reservation information 304A is satisfied, the reservation execution unit 305 starts the reservation target function unit 301 (self-diagnosis function unit). Then, the reservation target function unit 301 (automatic work function unit) performs the type of self-diagnosis (simple diagnosis or comprehensive diagnosis) specified by the command from the reservation execution unit 305.

[0106] A shovel user such as an operator of the shovel 100 or a manager of the work site uses the input device 52 to specify the execution conditions on the reservation reception screen of the display device 50 and confirm the reservation details. This allows the shovel user such as the operator of the shovel 100 or the manager of the work site to have the shovel 100 perform self-diagnosis during a time period when the key switch of the shovel 100 is turned off and the shovel 100 is not performing work. Also, a management device user such as the manager of the management device 200 or a support terminal user uses the input devices 240, 340 to specify the execution conditions on the reservation reception screen displayed on the display devices 230, 330 and confirm the reservation details. This allows the management device user such as the manager of the management device 200 or a support terminal user to perform self-diagnosis of the shovel 100 during a time period when the shovel 100 is not performing work, without having to send someone at the work site to the shovel 100 to perform setting operations related to the self-diagnosis function. Therefore, early detection of abnormalities, failures, and the like can be realized by periodically executing the self-diagnosis function, and a situation in which the self-diagnosis function is executed while the shovel 100 is working and the processing efficiency of the controller 30 is reduced can be prevented. In other words, it is possible to ensure both safety by early detection of abnormalities, failures, and the like of the shovel 100 and the operability of the shovel 100. In addition, the manager of the work site and the manager of the management device 200 do not need to keep track of the execution status of the self-diagnosis of the shovel 100, and the efficiency of operation of the shovel 100 can be improved.

[0107] <Fourth example of reservation function (operation restriction reservation function)> Next, a reservation function for executing the operation restriction function of the shovel 100 (hereinafter, "operation restriction reservation function") will be described with reference to Fig. 6 (Figs. 6A and 6B). Specifically, a reservation function for executing the operation time restriction function of the shovel 100 (hereinafter, "operation time restriction reservation function"), a reservation function for executing the output restriction function (hereinafter, "output restriction reservation function"), and a reservation function for executing the air-conditioning restriction function (hereinafter, "air-conditioning restriction reservation function") will be described.

[0108] Figures 6A and 6B are diagrams for explaining a fourth example (operation restriction reservation function) of the reservation function of the shovel 100. Specifically, Figure 6A is a diagram showing execution conditions (date and time conditions) for the operation time restriction reservation function and the output restriction reservation function of the shovel 100 on both weekdays (specifically, Monday to Friday other than holidays) and holidays (specifically, holidays from Monday to Friday). Figure 6B is a diagram showing execution conditions (date and time conditions) for the air conditioning restriction reservation function of the shovel 100 on both weekdays (specifically, Monday to Friday other than holidays) and holidays (specifically, holidays from Monday to Friday).

[0109] As shown in FIG. 6A, in this example, on weekdays, the excavator 100, under the control of the controller 30 (the reservation executor 305 and the reservation target function unit 301), limits the operation permission time zone of the excavator 100 to 8:00 to 12:00 and 13:00 to 17:00. In other words, 、 Under the control of the controller 30, the shovel 100 prohibits its own operation (i.e., the key switch is in the ON state) before 8:00, between 12:00 and 13:00, and after 17:00. Furthermore, on holidays, under the control of the controller 30, the shovel 100 limits the operation permission time period to between 9:00 and 12:00, and between 13:00 and 16:00. In other words, under the control of the controller 30, the shovel 100 prohibits its own operation (i.e., the key switch is in the ON state) before 9:00, between 12:00 and 13:00, and after 16:00.

[0110] During operation permission time slots on weekdays (between 8:00 and 12:00 and 13:00 and 17:00), the shovel 100, under the control of the controller 30, limits selectable operation modes to some operation modes with relatively low output so that the degree of restriction is relatively low (for example, only the second and third modes of the above-mentioned first to third modes are selectable). During holidays, the shovel 100, under the control of the controller 30, limits selectable operation modes to some operation modes with relatively low output so that the degree of restriction is relatively high (for example, only the third mode of the above-mentioned first to third modes is selectable).

[0111] In this example, the execution conditions of the operation time limit reservation function and the output limit reservation function can be specified by time conditions including a day of the week condition (Monday to Friday), a holiday condition, and a start time (8:00, 9:00, or 13:00) and end time (12:00, 16:00, or 17:00) of the operation permission time period and the output limit time period. The execution conditions of the output limit reservation function may include an operating situation condition (e.g., "the load condition of the shovel 100 is equal to or lower than a predetermined standard") and an environmental condition (e.g., "the soil of the terrain to be excavated around the shovel is relatively soft") instead of or in addition to the time condition. This is because, when the load condition of the shovel 100 is relatively high (higher than the predetermined standard), if the selectable operation modes are limited, the work efficiency of the shovel 100 may be significantly reduced.

[0112] The reservation execution unit 305 activates the reservation target function unit 301 (operation restriction function unit) when the operation permission time zone of the shovel 100 deviates based on the execution condition (time condition) related to the operation time restriction function specified in the reservation information 304A. Then, the reservation target function unit 301 (operation restriction function unit) fixes, for example, a key switch to OFF so that the shovel 100 (own machine) cannot be started when the shovel 100 is not operating (operating), and when the shovel 100 is operating (operating), turns the key switch OFF to forcibly stop the shovel 100. Furthermore, the reservation execution unit 305 activates the reservation target function unit 301 (operation restriction function unit) when the execution condition (time condition) related to the output restriction function specified in the reservation information 304A is established. Then, the reservation target function unit 301 (operation restriction function unit) restricts the selectable operation modes to some operation modes with relatively low output according to the restriction conditions specified in the reservation information 304A, that is, the conditions related to the available operation modes.

[0113] The manager of the work site, etc., uses the input device 52 to specify the execution conditions related to the operation time limit function and the output limit function on the reservation reception screen of the display device 50 and confirms the reservation contents. This allows the manager of the work site, etc., to restrict the operation time period of the shovel 100 and the selectable operation modes in the operation time period, etc., in accordance with the execution conditions, without visually checking the operation status of the shovel 100 at the work site. Also, the management device user such as the manager of the management device 200 or the support terminal user uses the input device 240, 340 to specify the execution conditions on the reservation reception screen displayed on the display device 230, 330 and confirms the reservation contents. This allows the management device user such as the manager of the management device 200 or the support terminal user (for example, the manager of the work site, etc.) to restrict the operation time period of the shovel 100 and the selectable operation modes in accordance with the execution conditions, without having someone at the work site check the operation status of the shovel 100. Therefore, the work site manager, the manager of the management device 200, etc. can strictly manage the operating hours of the shovel 100 at the work site, and can prevent the shovel 100 from being used in an unnecessarily high-power operating mode. This can reduce noise at the work site in the early morning or after the evening, and improve the fuel efficiency (energy saving) of the shovel 100. In addition, the work site manager, the manager of the management device 200, etc. do not need to keep track of the operating status of the shovel 100, and can improve the efficiency of the operation of the shovel 100.

[0114] Also, as shown in FIG. 6B, in this example, on weekdays (in summer) (specifically, Monday to Friday other than holidays), the shovel 100, under the control of the controller 30 (the reservation execution unit 305 and the reservation target function unit 301), prohibits the use of the air conditioner (cooling) in the cabin 10 before 8:00, from 12:00 to 13:00, and after 17:00. In other words, under the control of the controller 30, the shovel 100 does not start the air conditioner cooling even if the operation unit for starting the air conditioner cooling is turned ON before 8:00, from 12:00 to 13:00, and after 17:00. Also, on weekdays (in summer), the shovel 100, under the control of the controller 30, limits the set temperature of the air conditioner in the cabin 10 to 28° C. or higher for four hours from 8:00 to 12:00, and limits the set temperature of the air conditioner in the cabin 10 to 25° C. or higher for four hours from 13:00 to 17:00. In other words, under the control of the controller 30, the shovel 100 restricts the set temperature of the air conditioner in the cabin 10 so that it cannot be set below 25°C for a four-hour period from 8:00 to 12:00, and restricts the set temperature of the air conditioner in the cabin 10 so that it cannot be set below 25°C for a four-hour period from 13:00 to 17:00. Furthermore, on (summer) holidays (specifically, holidays from Monday to Friday), the shovel 100, under the control of the controller 30, prohibits the use of the air conditioner (cooling) in the cabin 10 before 9:00, from 12:00 to 13:00, and after 16:00. Furthermore, on (summer) holidays, the shovel 100, under the control of the controller 30, restricts the set temperature of the air conditioner in the cabin 10 to 28°C or higher for a three-hour period from 9:00 to 12:00, and restricts the set temperature of the air conditioner in the cabin 10 to 25°C or higher for a three-hour period from 13:00 to 16:00.

[0115] In this example, the execution conditions of the air-conditioning restriction reservation function may be specified by time conditions including a date condition corresponding to summer, a day of the week condition (Monday to Friday), a holiday condition, and a start time (8:00, 9:00, or 13:00) and an end time (12:00, 16:00, or 17:00) of the time period during which cooling operation is permitted and the time period during which the set temperature is restricted. The execution conditions of the air-conditioning restriction reservation function may include an environmental condition (e.g., "the outside air temperature is equal to or higher than a first temperature and equal to or lower than a second temperature") instead of or in addition to the time condition. The reason why the set temperature of the air conditioner may be unnecessarily lowered by the operator is considered to be a situation in which the outside air temperature is relatively high, such as in summer (i.e., a situation in which the outside air temperature is equal to or higher than the first temperature). Also, in a situation in which the outside air temperature is too high (i.e., a situation in which the outside air temperature exceeds the second temperature), the health of the operator in the cabin 10 should be prioritized over fuel saving of the excavator 100.

[0116] The reservation execution unit 305 activates the reservation target function unit 301 (operation restriction function unit) when the cooling operation permission time zone is exceeded based on the execution condition for the air-conditioning restriction reservation function specified in the reservation information 304A. The reservation target function unit 301 (operation restriction function unit) keeps the operation related to the cooling of the air conditioner invalid when the air conditioner is not operating, and forcibly stops the cooling of the air conditioner when the air conditioner is operating. The reservation execution unit 305 also activates the reservation target function unit 301 (operation restriction function unit) when the execution condition for the restriction of the set temperature of the cooling restriction function is satisfied. The reservation target function unit 301 (operation restriction function unit) keeps the setting operation invalid that deviates from the restriction condition for the set temperature (for example, 25°C or higher, or 28°C or higher) specified in the reservation information 304A.

[0117] The manager of the work site, etc., uses the input device 52 to specify the execution conditions related to the air conditioning restriction reservation function on the reservation reception screen of the display device 50 and confirms the reservation contents. This allows the manager of the work site, etc., to restrict the use time period of the air conditioning device and the set temperature during the use time period in accordance with the execution conditions, without visually checking the use status of the air conditioning device in the shovel 100 at the work site. Also, a management device user such as the manager of the management device 200 or a support terminal user uses the input devices 240, 340 to specify the execution conditions on the reservation reception screen displayed on the display devices 230, 330 and confirms the reservation contents. This allows the management device user such as the manager of the management device 200 or a support terminal user (for example, the manager of the work site) to restrict the use time period of the air conditioning device of the shovel 100 and the set temperature during the use time period in accordance with the execution conditions, without having someone at the work site check the use status of the air conditioning device of the shovel 100. Therefore, the work site manager, the manager of the management device 200, etc. can prevent the air conditioning device of the shovel 100 at the work site from being used unnecessarily outside the work hours at the work site or from being used at an unnecessarily low set temperature. This can improve the fuel efficiency (energy saving) of the shovel 100. In addition, the work site manager, the manager of the management device 200, etc. do not need to keep track of the usage status of the air conditioning device of the shovel 100, and the efficiency of the operation of the shovel 100 can be improved.

[0118] <5th example of reservation function (reservation function for executing multiple reservation target functions)> Next, a reservation function for the execution of a plurality of reservation target functions of the excavator 100 will be described with reference to FIG.

[0119] Fig. 7 is a diagram illustrating a fifth example of the reservation function of the shovel 100. Specifically, Fig. 7 is a diagram illustrating an overview of the execution conditions of the reservation function related to the execution of a plurality of reservation target functions of the shovel 100.

[0120] In this example, the shovel 100 has reservation functions related to the execution of a plurality of reservation target functions. Specifically, the shovel 100 has reservation functions related to the execution of the reservation target functions of the first to fourth examples described above (warm-up operation reservation function, automatic work reservation function, self-diagnosis reservation function, operation time limit reservation function, output limit reservation function, and air conditioning limit reservation function).

[0121] As shown in FIG. 7, in the excavator 100, execution conditions are defined for each type of reservation function.

[0122] For example, the execution conditions for the warm-up operation reservation function may be defined, as described above, by time conditions including a day of the week condition and a start-up time condition for the shovel 100. Furthermore, for example, the execution conditions for the warm-up operation reservation function may be defined, as described above, by environmental conditions including a temperature-related condition in addition to the time condition.

[0123] Also, for example, the execution conditions of the automatic work reservation function may be defined by the time conditions for each target automatic work, as described above. Also, the execution conditions of the automatic work reservation function may be defined by the operating status conditions of the excavator 100 instead of or in addition to the time conditions, depending on the content of the target automatic work and its order relationship with other automatic works, as described above.

[0124] Also, for example, the execution conditions of the self-diagnosis reservation function may be defined by time conditions including a day of the week condition and a start time condition of the self-diagnosis function, as described above. Also, depending on the content of the self-diagnosis, the execution conditions of the self-diagnosis reservation function may be defined by operating status conditions of the excavator 100 instead of or in addition to the time conditions, as described above.

[0125] Also, for example, the execution condition of the driving time limit reservation function may be defined as a time condition as described above.

[0126] Also, for example, the execution conditions of the output limit reservation function may be stipulated by time conditions as described above. Also, the execution conditions of the output limit reservation function may be stipulated by operating status conditions or environmental conditions instead of or in addition to time conditions as described above.

[0127] For example, the execution conditions of the air-conditioning restriction reservation function may be defined by time conditions as described above. For example, the execution conditions of the air-conditioning restriction reservation function may be defined by environmental conditions including conditions related to temperature instead of or in addition to the time conditions as described above.

[0128] In this example, the shovel user makes a predetermined input through the input device 52, and can cause the controller 30 to set a predetermined execution condition for each type of reservation function. Similarly, the management device user or the support terminal user makes a predetermined input through the input devices 240, 340, and can cause the controllers 210, 310 to set a predetermined execution condition for each type of reservation function. Therefore, the shovel 100 can automatically execute a plurality of different reservation target functions in response to a user request.

[0129] [Example of reservation screen] Next, with reference to FIG. 8 (FIGS. 8A and 8B), a specific example of a reservation screen displayed on the display device 50 of the shovel 100, the display device 230 of the management device 200, or the display device 330 of the support terminal 300 will be described.

[0130] 8A and 8B are diagrams for explaining specific examples of reservation screens displayed on the display device 50, 230, 330. Specifically, FIG. 8A is a diagram showing an example of a reservation reception screen displayed on the display device 50 of the shovel 100. More specifically, FIG. 8A is a diagram showing an example (reservation target function selection screen 710) of a reservation reception screen for selecting a function to be reserved (hereinafter, "reservation target function selection screen") displayed on the display device 50. Also, FIG. 8B is a diagram showing an example (shovel operator selection screen 720) of a shovel operator selection screen displayed on the display device 330 of the support terminal 300.

[0131] 8A may be displayed on the display device 230 of the management device 200 or the display device 330 of the support terminal 300. Also, a screen similar to the excavator / operator selection screen 720 of FIG. 7B may be displayed on the display device 230 of the management device 200.

[0132] As shown in FIG. 8A, a reservation target function selection screen 710 includes a list 711 showing reservation target functions and a selection icon 712.

[0133] Selectable reservation target functions are listed in the list 711. In this example, the list 711 includes list icons ("1. Warm-up operation reservation", "2. Self-diagnosis reservation", "3. Operation restriction reservation", "4. Automatic work reservation", etc.) corresponding to the warm-up operation function, self-diagnosis function, operation restriction function, automatic work function, etc. of the shovel 100, and the list icons are arranged vertically. A shovel user such as an operator of the shovel 100 or a manager of the work site can select and confirm any one type of reservation target function in the list 711 by using the input device 52 to move a selection icon 712 on the reservation target function selection screen 710 vertically.

[0134] When the selection of any one of the types of reservation target functions in the list 711 is confirmed, the display device 50 displays a reservation reception screen (hereinafter, "execution condition setting screen") for setting execution conditions corresponding to the type of reservation target function selected from the reservation target function selection screen 710. Then, a shovel user such as an operator of the shovel 100 or a work site manager can complete (confirm) the reservation for the execution of the reservation target function selected on the reservation target function selection screen 710 by setting and confirming the execution conditions via the input device 52.

[0135] As shown in FIG. 8B, the shovel / operator selection screen 720 includes a list 721 of a plurality of selectable shovels 100 and a list 722 of selectable operators.

[0136] The support terminal user can select and confirm any one of the shovels 100 listed in the list 721 through the input device 340 (for example, a touch panel implemented on the display device 330), thereby transitioning the display content of the display device 330 to a reservation target function selection screen (see FIG. 8A) for the selected one of the shovels 100. Then, the support terminal user can select the reservation target function and set the execution conditions through the reservation target function selection screen and the subsequent execution condition setting screen, and specifically, use the reservation function of the selected one of the shovels 100.

[0137] Furthermore, the support terminal user can select and confirm one of the operators listed in the list 722 through the input device 340, thereby transitioning the display contents of the display device 330 to a reservation target function selection screen (see FIG. 8A) related to the shovel 100 that the selected operator is scheduled to board shortly. The support terminal user can then select the reservation target function and set the execution conditions through the reservation target function selection screen and the subsequent execution condition setting screen, and specifically use the reservation function of the shovel 100 corresponding to the selected operator. Therefore, the support terminal user can select a reservation target function for which a reservation is to be made based on the reservation function from among the multiple reservation target functions, according to the attributes, etc., of the operator who will board the shovel 100, and set execution conditions related to the execution of the reservation target function.

[0138] [Effect] Next, the operation of the work support system SYS (the shovel 100, the management device 200, and the support terminal 300) according to this embodiment will be described.

[0139] In this embodiment, the shovel 100 accepts a reservation for the execution of a predetermined function of the shovel 100 in response to a predetermined input accepted from a shovel user or a reservation command signal received from an external device (specifically, the management device 200 or the support terminal 300 via the management device 200). Then, the shovel 100 executes the predetermined function in response to the execution conditions specified in the accepted reservation (reservation information 304A).

[0140] As a result, the operator of the shovel 100, a manager of the work site, etc. can have the shovel 100 automatically execute a predetermined function in accordance with the execution conditions specified in the reservation, without having to go to the shovel 100 themselves or send someone to the shovel 100. Furthermore, the operator of the shovel 100, a manager of the work site, etc. can appropriately set the execution conditions for the predetermined function to reduce dead time, etc. of the shovel 100 and improve the work efficiency of the shovel 100. Thus, the shovel 100 can support more efficient operation of its own machine.

[0141] In this embodiment, the predetermined function to be reserved may include a function of automatically starting up and preparing to start work, specifically, a function of performing a warm-up operation (warm-up operation function).The excavator 100 may automatically start up and prepare to start work (warm-up operation) according to time conditions including at least one of date, time, day of the week, and period, and execution conditions including at least one of environmental conditions, which are specified in the accepted reservation (reservation information 304A).

[0142] This allows the operator of the shovel 100, a manager of the work site, or the like to automatically start the shovel 100 and have it perform preparations for work such as warming up (warming up) according to time conditions, without the operator having to go to the shovel 100 himself or herself or have someone go to the shovel 100. Thus, the shovel 100 can specifically support more efficient operation of its own machine.

[0143] The preparation for starting work may be something other than a warm-up operation. For example, when a mobile crane is included in the work support system SYS instead of or in addition to the excavator 100, the preparation for starting work may be an operation of automatically raising the crane boom of the mobile crane from a tilted state while the excavator is stopped.

[0144] In this embodiment, the predetermined function to be reserved may include a self-diagnosis function. The shovel 100 may perform self-diagnosis in accordance with time conditions including at least one of date, time, day of the week, and period, and execution conditions including at least one of operating status conditions, which are specified in the accepted reservation (reservation information 304A).

[0145] This allows the operator of the shovel 100, a manager of the work site, or the like to have the shovel 100 automatically perform a self-diagnosis in accordance with time conditions and operating conditions, without the operator having to go to the shovel 100 himself or herself or having someone go to the shovel 100. Thus, the shovel 100 can specifically support more efficient operation of its own machine.

[0146] In this embodiment, the predetermined function to be reserved may include a function to automatically perform a predetermined task (automatic task function). The shovel 100 may automatically perform the predetermined task according to execution conditions including at least one of time conditions including at least one of date, time, day of the week, and period, operating status conditions, and environmental conditions, which are specified in the accepted reservation (reservation information 304A).

[0147] This allows the operator of the shovel 100, a manager of the work site, or the like to automatically perform a predetermined task in accordance with time conditions and the like, without the need to go to the shovel 100 himself or herself or to send someone to the shovel 100. Thus, the shovel 100 can specifically support more efficient operation of its own machine.

[0148] In this embodiment, the predetermined work automatically performed by the shovel 100 may include a plurality of works (for example, excavation work, backfilling work, shaping work, etc.). The shovel 100 automatically performs the plurality of works in sequence according to execution conditions specified in the accepted reservation (reservation information 304A) and including at least one of time conditions including at least one of date, time, day of the week, and period for each of the plurality of works, operating status conditions, and environmental conditions.

[0149] This allows the operator of the shovel 100 or a site manager to sequentially perform a series of multiple tasks to be performed in a day, for example, in accordance with time conditions, etc., without the operator having to go to the shovel 100 himself or having someone go to the shovel 100. Thus, the shovel 100 can support more efficient operation of its own machine.

[0150] In this embodiment, the predetermined function to be reserved may include an operation limiting function that limits the operation of the excavator 100. The excavator 100 may limit the operation of the excavator 100 according to execution conditions that are specified in the accepted reservation (reservation information 304A) and include at least one of time conditions including at least one of date, day of the week, and period, operation status conditions, and environmental conditions.

[0151] This allows the manager of the work site or the like to restrict the operation of the shovel 100 in accordance with time conditions and the like, without the manager having to go to the shovel 100 himself or herself or have someone go to the shovel 100. Thus, for example, by appropriately restricting the operation of the shovel 100 in accordance with operational requirements of the shovel 100, the shovel 100 can specifically support more efficient operation of the shovel itself.

[0152] In this embodiment, the operation restriction function may include a function for restricting a time period during which the operation of the excavator 100 is permitted (operation time restriction function). The excavator 100 may prohibit the start of the excavator 100 in accordance with the execution conditions including time conditions including at least one of date and time, day of the week, and period specified in the accepted reservation (reservation information 304A), and may automatically stop (forcibly stop) the excavator 100 in accordance with the execution conditions including time conditions including at least one of date and time, day of the week, and period specified in the reservation.

[0153] This allows the manager of the work site or the like to more efficiently and strictly manage the operating time of the shovel 100. Therefore, the shovel 100 can more specifically support more efficient operation of its own machine.

[0154] Furthermore, in this embodiment, the shovel 100 may automatically stop (forcibly stop) after automatically moving to a predetermined location in relation to the execution of the operation time limit function.

[0155] This allows the shovel 100 to suppress a situation in which the shovel 100 is forced to stop on a slope, for example. Therefore, the shovel 100 can ensure the safety of the shovel 100 while supporting strict management of the operation time of the shovel 100.

[0156] In the present embodiment, the operation limiting function may include a function (output limiting function) for limiting the output of the excavator 100 to a relatively low level. The excavator 100 may limit its operation to a relatively low output level according to execution conditions including time conditions including at least one of date, time, day of the week, and period, operating status conditions, and environmental conditions, all of which are specified in the accepted reservation (reservation information 304A).

[0157] As a result, by appropriately setting the execution conditions, the shovel 100 can prevent a situation in which the shovel 100 performs its own work with excessive output, which would result in relatively loud noise or deterioration of the shovel's fuel efficiency (energy saving performance).

[0158] In this embodiment, the shovel 100 may have a plurality of operation modes with mutually different outputs. The shovel 100 may limit the availability of only some of the operation modes with relatively low outputs according to execution conditions including at least one of time conditions including at least one of date, time, day of the week, and period, operating status conditions, and environmental conditions specified in the accepted reservation (reservation information 304A).

[0159] Thereby, the shovel 100 can specifically limit the operation of its own machine so that the output of its own machine becomes relatively low.

[0160] In addition, in this embodiment, the operation restriction function may include a function (air conditioning restriction function) for restricting the operation related to cooling in the air conditioning device of the cabin 10. Then, the excavator 100 may restrict the time period during which the cooling operation of the air conditioning device is permitted or may restrict the operation of the air conditioning device so that the cooling set temperature becomes relatively high, depending on the execution conditions including at least one of the date and time conditions and the environmental conditions specified in the accepted reservation.

[0161] This enables the shovel 100 to strictly manage the usage of air conditioning in its own air conditioning unit, and suppress a deterioration in the fuel efficiency (energy saving) of the own machine due to unnecessary use of air conditioning or use of air conditioning with an unnecessarily low set temperature.

[0162] Furthermore, in this embodiment, the management device 200 and the support terminal 300 accept a reservation for the execution of a predetermined function in the shovel 100 in response to a predetermined input received from a management device user and a support terminal user, respectively. Then, the management device 200 and the support terminal 300 transmit a signal (reservation command signal) requesting a reservation to the shovel 100 (in the case of the support terminal 300, the signal is transmitted via the management device 200), thereby causing the shovel 100 to execute the predetermined function in accordance with the conditions specified in the accepted reservation.

[0163] This allows the management device 200 and the support terminal 300 to make a reservation for the execution of a predetermined function from outside the shovel 100. Therefore, a management device user such as an administrator of the management device 200 or a support terminal user can have the shovel 100 automatically execute a predetermined function according to the execution conditions specified in the reservation, without going to the shovel 100 himself or sending someone to the shovel 100. Furthermore, a management device user such as an administrator of the management device 200 or a support terminal user can appropriately set the execution conditions of the predetermined function to suppress dead time, etc. of the shovel 100 and improve the work efficiency of the shovel 100. Therefore, the management device 200 and the support terminal 300 can support more efficient operation of the shovel 100.

[0164] In addition, in this embodiment, the management device 200 and the support terminal 300 may accept reservations for each of multiple shovels 100, or for each of multiple operators corresponding to multiple shovels 100, and transmit a signal to the shovel 100 requesting the accepted reservation.

[0165] This allows the management device 200 and the support terminal 300 to make reservations for the execution of a predetermined function from outside the shovel 100 for multiple shovels 100 and operators of multiple shovels 100. Thus, the management device 200 and the support terminal 300 can support more efficient operation of the shovel 100.

[0166] [Transformation / Change] Although the embodiments have been described in detail above, the present disclosure is not limited to such specific embodiments, and various modifications and variations are possible within the scope of the gist of the present disclosure described in the claims.

[0167] For example, in the above embodiment, a reservation for the execution of a reserved function is accepted by the shovel user operating the reservation screen displayed on the display device 50 through the input device 52, but a reservation may be accepted by other methods. For example, the controller 30 may provide a voice assistant to the shovel user through a sound output device such as a speaker. The controller 30 may be configured to be able to accept a reservation for the execution of a reserved function of the shovel 100 from the shovel user through an interactive interface using the input device 52 (voice input device). Also, in the management device 200 and the support terminal 300, a reservation for a reserved function of the shovel 100 from a management device user or a support terminal user may be accepted in a similar manner.

[0168] In the above-described embodiment and modified examples, the excavator 100 has various operating elements, such as the lower traveling body 1, the upper rotating body 3, the boom 4, the arm 5, and the bucket 6, all of which are hydraulically driven, but some of these elements may be electrically driven. In other words, the configurations disclosed in the above-described embodiments may be applied to hybrid excavators, electric excavators, and the like.

[0169] Finally, this application claims priority based on Japanese Patent Application No. 2019-036481, filed on February 28, 2019, the entire contents of which are incorporated herein by reference. [Explanation of symbols]
