Description

Technical Field

[0001] The present invention relates to a system for assisting the attachment and detachment work of optional equipment for a working machine.

Background Art

[0002] In recent years, working machines have been designed to handle various work applications by adding functions (options) composed of multiple devices. In addition, in order to handle complex work applications, it is also assumed that a plurality of different options can be added to a single working machine. Such additional work may be carried out not only by service personnel but also by customers.

[0003] Along with this, a plurality of technologies related to providing maintenance information for equipment attached to a working machine and assisting in maintenance work have been devised.

[0004] As a technology for displaying the inspection priority (failure risk) for each item of a plurality of maintenance operations performed on a working machine and presenting the required equipment for each inspection operation, for example, there is one described in Patent Document 1.

[0005] In addition, as a technology for recognizing and providing information on optional equipment attached to a working machine, for example, there is one described in Patent Document 2.

Summary of the Invention

Problems to be Solved by the Invention

[0007] However, when adding or deleting a plurality of options at once, the operator (customer or service staff) needs to understand the equipment required for each option, determine the work procedure while referring to a manual or the like, and perform the work. For the increasing number of options year by year, it is time-consuming for the operator to follow this procedure every time an option is added.

[0008] In Patent Document 1, the priority order for each work item can be displayed, but the rearrangement of items and the presentation of specific work methods cannot be done. Therefore, the labor of rearranging a large number of work items and the labor of referring to the manual to know the work method for each item remain.

[0009] Furthermore, depending on the option, the functions of other options may be required as a prerequisite for realizing the function. Therefore, if the operator forgets to install the equipment of other options that are required as a prerequisite, there is a risk that the newly added option will not operate.

[0010] In Patent Document 2, the newly installed equipment can be recognized individually, but as described above, since an option is a function composed of a plurality of pieces of equipment, it cannot be associated with the option. Therefore, it is not possible to grasp all the equipment that needs to be attached and detached when adding an option, and there is a risk of forgetting to attach and detach some of the equipment.

[0011] For example, if the installation and calibration work for the equipment for the toe display function (MG: Machine Guidance) is not completed, the installation and calibration work for the equipment for the toe control function (MC: Machine Control) cannot be performed. If the installation work for the MC equipment is carried out ignoring the mutual relationship between these options, there is a risk that the accuracy of the MC cannot be ensured.

[0012] The present invention has been made in view of the above problems, and an object thereof is to provide an attachment / detachment support system for option equipment that can reduce the labor of attaching / detaching option equipment to a work machine, suppress work errors, and guarantee the operation of options newly added to the work machine.

Means for Solving the Problems

[0013] In order to achieve the above object, the present invention provides an attachment / detachment support system for option equipment including a controller that controls a function for assisting the attachment / detachment operation of option equipment to a work machine, wherein the controller includes an attachment / detachment target determination unit that determines an attachment / detachment target device, which is an option device to be attached / detached; a work procedure creation unit that creates an attachment / detachment work procedure for the attachment / detachment target device in consideration of the interrelationship of a plurality of the option devices; and a deviation determination unit that outputs a connection device deviation warning when the option device instructed to be attached / detached next in the attachment / detachment work procedure is different from the newly attached / detached option device.

Effects of the Invention

[0014] According to the present invention, it is possible to reduce the labor of attaching / detaching option equipment to a work machine, suppress work errors, and guarantee the operation of options newly added to the work machine.

[0020] Figure 2 is a configuration diagram of an optional equipment attachment / detachment support system. The optional equipment attachment / detachment support system 200 is mounted on the hydraulic excavator 100 and includes a control controller 1, an information controller 4, and a display controller 5, which are respectively provided in the cab 105 on the upper swing body 102. Each controller is composed of a processing device such as a CPU, a storage device such as a memory or a hard disk, and an input / output interface for performing signal input / output with external devices, and realizes each function by executing a program stored in the storage device. In addition, controllers according to applications and functions are mounted on the vehicle body of the hydraulic excavator 100 in addition to the controllers shown in Figure 2.

[0021] The control controller 1 performs control for driving a driven body such as the front working machine 103 of the working machine. An optional device 3 is connected to the control controller 1 via a connection device 2. The optional device 3 is a device required for a function (hereinafter referred to as an option) added to the hydraulic excavator 100. The connection device 2 has a function of transmitting the name of the optional device 3 to the control controller 1.

[0022] In addition, the optional device 3 may be connected to one or more controllers other than the control controller 1. Further, the optional device is not limited to controllers and electronic devices, and may be a device that cannot be electrically connected (for example, an attachment, a hydraulic device, etc.). The optional device that cannot be electrically connected is attached to the vehicle body without passing through the connection device 2, and the name of the optional device is transmitted to the information controller 4 by the operator manually inputting it via the display device 6. The display device 6 also serves as an input device for inputting information to the information controller 4, and is composed of, for example, a touch panel monitor installed in the cab 105.

[0023] The information controller 4 collects operation information and the like from controllers connected to the vehicle body such as the control controller 1 and the display controller 5 via the vehicle body network 7. The information controller 4 includes a detachment target determination unit 4a, a work procedure creation unit 4b, and a deviation determination unit 4c.

[0024] The attachment / detachment target determination unit 4a has a mounted device acquisition function 20, a necessary device search function 21, and a configuration comparison function 22, and stores connection device name information 10, current configuration information 11, optional necessary configuration information 12, option relationship information 13, a device configuration database 14, and option change instruction information 15.

[0025] The work procedure creation unit 4b has a priority determination function 40 and a procedure creation function 41, and stores device priority information 30, a work manual 31, and an attachment / detachment work procedure 32.

[0026] The deviation determination unit 4c has an attachment / detachment result determination function 60 and stores a connection device deviation warning 50.

[0027] The display controller 5 outputs the information instructed to be displayed from the information controller 4 to the display device 6, and transmits the information input via the display device 6 to the information controller 4.

[0028] FIG. 3 is a diagram showing an example of the current configuration information 11. The current configuration information 11 summarizes information on the devices currently connected to the vehicle body. In the example of FIG. 3, it shows that LiDAR and a camera are currently connected to the vehicle body.

[0029] FIG. 4 is a diagram showing an example of the option change instruction information 15. The option change instruction information 15 summarizes information on the options (hereinafter referred to as changed options) that the operator has instructed to add or delete via the display device 6. In the example of FIG. 4, it shows that the addition of remote control has been instructed.

[0030] FIG. 5 is a diagram showing an example of the inter-option relationship information 13. The inter-option relationship information 13 summarizes information representing the mutual relationship between options. Among the options, there are those that function on the premise that other options are functioning, and the other options are referred to as subordinate options. In the example of FIG. 5, the subordinate option of remote automation is remote control, the subordinate options of remote control are MC and obstacle detection, and it shows that the subordinate option of MC is MG.

[0031] FIG. 6 is a diagram showing an example of the device configuration database 14. The device configuration database 14 summarizes information on the devices required for each option. In the example of FIG. 6, it shows that the devices required by MG (option number 4) are an angle sensor and an IMU.

[0032] FIG. 7 is a diagram showing an example of the option required configuration information 12. The option required configuration information 12 summarizes information on the devices required by the change option. In the example of FIG. 7, it shows that the devices required by the change option are an angle sensor and an IMU.

[0033] FIG. 8 is a diagram showing a method for determining the detachable device. Details of FIG. 8 will be described later.

[0034] FIG. 9 is a diagram showing an example of the detachable device information 16. In this example, it shows that the angle sensor and the IMU are the attachment targets, and the LiDAR is not a detachable target.

[0035] FIG. 10 is a diagram showing an example of the mutual relationship between the change option and the subordinate option. In this example, the mutual relationship between the change option and the subordinate option is represented by the tree diagram 33. The change option "remote control" is arranged at the top of the tree diagram 33, and the subordinate options "MC" and "obstacle detection" of "remote control" are arranged directly below it. The subordinate option "MG" of "MC" is arranged directly below "MC".

[0036] FIG. 11 is a diagram showing an example of device priority information 30. The device priority information 30 summarizes information representing the attachment / detachment order of devices required by the change option. In the example of FIG. 11, when adding "remote control", the attachment order of the devices is the angle sensor, IMU, and GNSS in that order, and when deleting "remote control", the removal order is the GNSS receiver, IMU, and angle sensor in that order.

[0037] FIG. 12 is a diagram showing an example of the attachment / detachment operation procedure 32. The attachment / detachment operation procedure 32 arranges the operation methods of the devices to be attached / detached extracted from the operation manual 31 according to the device priority information 30. In the example of FIG. 12, the operation methods are arranged in the order of the angle sensor, IMU, and GNSS receiver.

[0038] FIG. 13 is a diagram showing an example of the connected device detachment warning 50. The connected device detachment warning 50 is displayed on the display device 6 when a device different from the device to be attached / detached is attached / detached. The connected device detachment warning 50 includes an operation procedure for returning the erroneously attached / detached device to its state before attachment / detachment.

[0039] The processing of the optional device attachment / detachment support system 200 will be described with reference to FIGS. 14 to 22.

[0040] FIG. 14 is a flowchart showing the overall processing of the optional device attachment / detachment support system 200.

[0041] First, it is determined whether there is a change option (step S101). If the determination result in step S101 is NO, the process returns to step S101.

[0042] If the determination result in step S101 is YES, for the change option, the optional device to be attached / detached (hereinafter referred to as the device to be attached / detached) is determined (step S102). The process of step S102 is performed by the attachment / detachment target determination unit 4a (shown in FIG. 2). The details of step S102 will be described later.

[0043] Following step S102, a detachment / attachment operation procedure 32 is created (step S103). The process of step S103 is performed by a procedure creation unit 4b (shown in FIG. 2). Details of step S103 will be described later.

[0044] Following step S103, it is monitored whether the actual detachment / attachment operation by the operator deviates from the detachment / attachment operation procedure 32 (step S104), and this flow ends. The process of step S104 is performed by a deviation determination unit 4c (shown in FIG. 2). Details of step S104 will be described later.

[0045] Details of step S102 in FIG. 14 will be described with reference to FIG. 15.

[0046] First, current configuration information 11 is generated (step S201). Specifically, first, the name of the device currently connected to the vehicle body (hereinafter referred to as the connected device) (connected device name information 10) is inquired. For example, when the connected device is a controller, the controller name is directly obtained. On the other hand, when the target device is an electronic device such as a sensor, the name of the device is obtained from the connected controller. Then, the obtained names of the connected devices are listed and saved as the current configuration information 11. In the example of FIG. 3, "LiDAR" and "camera" are obtained as the names of the connected devices.

[0047] Following step S201, option required configuration information 12 is generated (step S202). Details of step S202 will be described with reference to FIG. 16.

[0048] First, option change instruction information 15 is read (step S301).

[0049] Following step S301, options are extracted from option relationship information 13 (step S302), and it is determined whether they match the changed options (step S303). If the determination result of step S303 is NO, the process returns to step S302.

[0050] If the determination result in step S303 is YES, then the lower-level options of the change option are extracted from the option relationship information 13 (step S304), and it is determined whether the information of all the lower-level options has been extracted (step S305). In the example of FIG. 5, for example, when the change option is remote control, MC and obstacle detection are extracted as lower-level options, and further MG is extracted as a lower-level option of MC. On the other hand, since there are no lower-level options for MG and obstacle detection, all the lower-level options have been extracted above.

[0051] If the determination result in step S305 is YES, then the necessary devices for each of the change option and all the lower-level options extracted in step S304 are extracted from the device configuration database 14 (step S306). In the example of FIG. 6, for example, for MG (option number 4), an angle sensor and an IMU are extracted as necessary devices.

[0052] Following step S306, the list of necessary devices extracted in step S306 is saved as the option necessary configuration information 12 (step 307), and the flow ends.

[0053] Return to FIG. 15, following step S202, the attachable / detachable device information 16 is generated (step S203), and the flow ends. The details of step S203 will be described with reference to FIG. 17.

[0054] First, the option necessary configuration information 12 is read (step S401).

[0055] Following step S401, the current configuration information 11 is read (step S402).

[0056] Following step S402, the current configuration information 11 is compared with the optional required configuration information 12, and it is determined whether each device is a device to be attached or detached according to the determination method shown in FIG. 8 (step S403). In FIG. 8, "〇" indicates that the device to be determined is in a mounted state, "×" indicates that the device to be determined is not mounted, and there are 4 patterns of combinations of the state in the current configuration information 11 and the state in the optional required configuration information 12. "Attach" in the determination result indicates that it is an attachment target, "Detach" indicates that it is a removal target, and "-" indicates that it is not an attachment / detachment target. Taking pattern 3 as an example, the state of the device to be determined in the current configuration information 11 is not mounted, but the state of the device to be determined in the optional required configuration information 12 is mounted. Therefore, the determination result is "Attach", indicating that it is an attachment target.

[0057] Following step S403, the determination result of step S403 is saved as the attachment / detachment target device information 16 (step S404), and the flow ends. In the example of FIG. 9, the angle sensor and the IMU are attachment targets, and the LiDAR is not an attachment / detachment target.

[0058] The details of step S103 in FIG. 14 will be described with reference to FIG. 18.

[0059] First, the priority of the device to be attached or detached is determined (step S501). The details of step S501 will be described with reference to FIG. 19.

[0060] First, the option relationship information 13 is read (step S601).

[0061] Following step S601, the device configuration database 14 is read (step S602).

[0062] Following step S602, the option change instruction information 15 is read (step S603).

[0063] Following step S603, determine the priorities of the change option and its subordinate options (step S604). The details of step S604 will be described with reference to FIG. 20.

[0064] First, extract options from the option relationship information 13 (step S701), and determine whether it matches the change option (step S702). If the determination result in step S702 is NO, return to step S701.

[0065] If the determination result in step S702 is YES, extract the subordinate options of the change option from the option relationship information 13 (step S703), and determine whether all subordinate options have been extracted (step S704). If the determination result in step S702 is NO, return to step S703.

[0066] If the determination result in step S704 is YES, create a tree diagram 33 (an example is shown in FIG. 10) representing the mutual relationship between the change option and its subordinate options (step S705).

[0067] Following step S705, perform a breadth-first search on the tree diagram 33 created in step S705, and assign priorities (hereinafter, depth priorities) according to the hierarchy depth to each option (step S706). In the example of FIG. 10, taking the priority "PRI: 1-(i)" assigned to the option as an example, the "1" part represents the depth priority. When the change option located at the vertex of the tree diagram 33 is the addition target, it is necessary to add the options in order from the option with the larger depth priority value. When the change option located at the vertex of the tree diagram 33 is the deletion target, it is necessary to delete the options in order from the option with the smaller depth priority value.

[0068] Following step S706, in the tree diagram 33, the priority within the same hierarchy (hereinafter, the breadth priority) is assigned to each option (step S707), and this flow ends. In the example of FIG. 10, taking the priority "PRI: 1-(i)" assigned to the option as an example, the part "(i)" represents the breadth priority. The breadth priority is assigned in order from 1 in ascending order of the option numbers, referring to the option numbers in the option relationship information 13, for example. Note that the method of assigning the breadth priority is not particularly limited as long as the same breadth priority does not exist within the same hierarchy. When comparing the priorities of options, the depth priority is prioritized over the breadth priority.

[0069] Returning to FIG. 19, following step S604, the priority of the required equipment is determined for each option (step S605). Here, the required equipment is associated in the order registered in the equipment configuration database 14 with respect to the priority of each option determined in step S604.

[0070] Following step S605, the priority of the required equipment determined in step S605 is saved as equipment priority information 30 (step S606), and this flow ends.

[0071] Returning to FIG. 18, following step S501, the attachment / detachment work procedure 32 is created (step S502), and this flow ends. The details of step S502 will be described with reference to FIG. 21.

[0072] First, the equipment information 16 to be attached / detached is read (step S801).

[0073] Following step S801, the equipment priority information 30 is read (step S802).

[0074] Following step S802, the work manual 31 is read (step S803). The work manual 31 summarizes information on the specific attachment procedures and post-attachment setting procedures (hereinafter, work methods) when attaching / detaching each piece of equipment.

[0075] Following step S803, determine the attachment / detachment order of the device to be attached / detached according to the device priority information 30 (step 804).

[0076] Following step S804, create an attachment / detachment work procedure 32 by associating the work manual 31 with the attachment / detachment order of the device to be attached / detached determined in step S804 (step S805).

[0077] Following step S805, save the attachment / detachment work procedure 32 created in step S804 (step S806), and end the flow.

[0078] The details of step S104 in FIG. 14 will be described with reference to FIG. 22.

[0079] First, load the attachment / detachment work procedure 32 (step S901).

[0080] Following step S901, based on the attachment / detachment work procedure 32, display the next device to be attached / detached and the working method (step 902).

[0081] Following step S902, generate the current configuration information 11 (step S903).

[0082] Following step S903, compare the current configuration information 11 generated in step S902 with the previously generated current configuration information 11, and extract the different devices (step S904). For example, when a new option monitor is connected, the option monitor is extracted as a different device.

[0083] Following step S904, determine whether there are different devices (step S905). If the determination result in step S905 is NO, return to step S903.

[0084] If the determination result in step S905 is YES, then the next device to be attached / detached is compared with the differential device acquired in step S904 (step S906), and it is determined whether or not they match (step S907). For example, if the next device to be attached / detached is a GNSS receiver, while an option monitor is extracted as the differential device, the determination result in step S907 will be NO.

[0085] If the determination result in step S907 is NO, a connection device deviation warning 50 is created and output to the display device 6 (step S908). In the case of the above specific example, as shown in FIG. 13, the removal procedures for the erroneously attached option monitor are displayed one by one in order. Note that the display device 6 may display the entire removal procedure or may cut out and display a part of it.

[0086] Subsequent to step 908, or if the determination result in step 907 is YES, it is determined whether or not the attachment / detachment of all devices to be attached / detached is completed (step S909). In the case of the above specific example, since at least the attachment of the GNSS receiver is not completed, the determination result in step 909 is NO.

[0087] If the determination result in step S909 is NO, the process returns to step S902, and if it is YES, the flow ends.

[0088] (Summary) In this embodiment, in the option device attachment / detachment support system 200 including the controller 4 that controls the function for assisting the attachment / detachment work of the option device 3 to the work machine 100, the controller 4 includes a detachment target determination unit 4a that determines the device to be attached / detached, which is the option device 3 to be attached / detached, a work procedure creation unit 4b that creates the attachment / detachment work procedure 32 of the device to be attached / detached based on the mutual relationship of the plurality of option devices 3, and a deviation determination unit 4c that outputs a connection device deviation warning 50 when the option device 3 instructed to be attached / detached next in the attachment / detachment work procedure 32 is different from the newly attached / detached option device 3.

[0089] According to the present embodiment configured as described above, the attachment / detachment operation procedure 32 of the device to be attached / detached is presented to the operator in the order considering the interrelationship of the plurality of option devices 3, and a warning is issued when an operation deviating from the attachment / detachment operation procedure 32 is performed. Thereby, it is possible to reduce the labor of the attachment / detachment operation of the option device 3 to the work machine 100, suppress work mistakes, and guarantee the operation of the newly added option to the work machine 100.

[0090] In addition, the option device attachment / detachment support system 200 in the present embodiment includes an input device 6 for instructing a change option that is an option to be added or deleted. The controller 4 generates current configuration information 11 representing the configuration of the option device 3 currently attached to the work machine 100 by the attachment / detachment target determination unit 4a, and based on the device configuration database 14 representing the configuration of the option device 3 required for each option and the option - to - option relationship information 13 representing the interrelationship of the plurality of option devices 3, generates option required configuration information 12 representing the configuration of the option device 3 required by the change option instructed by the input device 6, and determines the device to be attached / detached by extracting the difference between the option required configuration information 12 and the current configuration information 11. Thereby, it becomes possible to let the operator grasp only the option device 3 that requires an attachment / detachment operation.

[0091] In addition, the controller 4 in the present embodiment, by the operation procedure creation unit 4b, based on the device configuration database 14 and the option - to - option relationship information 13, generates device priority information 30 representing the attachment / detachment order of the option device 3 required by the change option instructed by the input device 6, extracts the operation method of the device to be attached / detached from the operation manual 31 in which the operation method for each option device 3 is described, and creates the attachment / detachment operation procedure 32 by arranging the operation methods of the device to be attached / detached according to the device priority information 30. Thereby, since it is not necessary for the operator to refer to the operation manual 31, it becomes possible to reduce the labor of the attachment / detachment operation.

[0092] Further, the controller 4 in the present embodiment causes the connection device deviation warning 50 to notify of returning the erroneously attached / detached option device 3 to the state before attachment / detachment. Thereby, it becomes possible to prompt the operator to quickly correct the work mistake.

[0093] As described above, the embodiments of the present invention have been described in detail. However, the present invention is not limited to the above-described embodiments and includes various modifications. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described.
