Description

Optional equipment attachment / detachment support system and work machine

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

[0002] In recent years, work machines have been adapted to various work applications by adding functions (options) that consist of multiple devices. It is also expected that multiple different options will be added to a single work machine to accommodate complex work applications. Such addition work may be performed not only by service personnel but also by the customer.

[0003] In response to this trend, several technologies have been devised for providing maintenance information and supporting maintenance work for devices attached to work machines.

[0004] For example, Patent Document 1 describes a technology that displays the inspection priority (failure risk) for each of a plurality of maintenance work items performed on a work machine and presents the equipment required for each inspection work.

[0005] Furthermore, a technology for recognizing optional equipment attached to a work machine and providing information thereon is disclosed, for example, in Patent Document 2.

[0006] JP 2020-102009 A JP 2013-151786 A

[0007] However, when adding or removing multiple options at once, the worker (customer or service personnel) must understand the equipment required for each option, determine the procedure by referring to the manual, etc. With the number of options increasing every year, it becomes time-consuming for the worker to go through this procedure every time an option is added.

[0008] In Patent Document 1, the priority of each task item can be displayed, but it is not possible to rearrange the items or present specific work methods. As a result, the user still has to work hard to rearrange a large number of task items and to refer to a manual to find out how to perform each task.

[0009] Furthermore, some options require other options to function as a prerequisite, so if an operator forgets to install other required options, the newly added option may not work.

[0010] In Patent Document 2, newly installed devices can be recognized individually, but as mentioned above, options cannot be linked to functions that are realized by multiple devices. Therefore, when adding an option, it is not possible to know all the devices that need to be attached or detached, and there is a risk that some devices may be forgotten to be attached or detached.

[0011] For example, if the installation and calibration of the equipment for the toe display function (MG: Machine Guidance) is not completed, the installation and calibration of the equipment for the toe control function (MC: Machine Control) cannot be performed. If the installation of the MC equipment is performed without considering the interrelationship between these options, the accuracy of the MC may not be ensured.

[0012] The present invention has been made in consideration of the above-mentioned problems, and its purpose is to provide an optional equipment attachment / detachment support system that can reduce the effort required for attaching / detaching optional equipment to / from a work machine while suppressing work errors and ensuring the operation of options newly added to a work machine.

[0013] In order to achieve the above object, the present invention provides an optional equipment attachment / detachment support system equipped with a controller that controls a function for supporting the attachment / detachment of optional equipment to / from a work machine, the controller comprising: an attachment / detachment target determination unit that determines an attachment / detachment target device, which is optional equipment to be attached or detached; a work procedure creation unit that creates an attachment / detachment work procedure for the attachment / detachment target device taking into account the interrelationships between a plurality of optional equipment; and a deviation determination unit that outputs a connected equipment deviation warning when the optional equipment instructed to be attached or detached next in the attachment / detachment work procedure differs from the newly attached or detached optional equipment.

[0014] According to the present invention, it is possible to reduce the effort required to attach and detach optional equipment to and from a work machine, while suppressing work errors, and to ensure the operation of options newly added to a work machine.

[0016] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In each drawing, the same reference numerals are used to designate the same components, and redundant description will be omitted where appropriate.

[0017] 1 is a schematic view of a hydraulic excavator equipped with an optional equipment attachment / detachment support system according to this embodiment. Note that the application of the optional equipment attachment / detachment support system according to the present invention is not limited to hydraulic excavators, but can also be applied to other work machines such as crawlers and wheel loaders.

[0018] 1 , the hydraulic excavator 100 includes a lower traveling structure 101, an upper rotating structure 102 rotatably mounted on the lower traveling structure 101, and a front work implement 103 rotatably mounted on the upper rotating structure 102. The lower traveling structure 101, the upper rotating structure 102, and the front work implement 103 form the vehicle body of the hydraulic excavator 100. The lower traveling structure 101 is driven by a traveling motor 104, and the upper rotating structure 102 is driven by a swing motor (not shown). The upper rotating structure 102 is provided with a cab 105 in which an operator sits.

[0019] The front working implement 103 has a boom 106 rotatably attached to the upper rotating body 102, an arm 107 rotatably attached to the tip of the boom 106, and a bucket 108 rotatably attached to the tip of the arm 107. The boom 106 is driven by a boom cylinder 109, the arm 107 is driven by an arm cylinder 110, and the bucket 108 is driven by a bucket cylinder 111.

[0020] 2 is a configuration diagram of the 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, each of which is provided in the operator's cab 105 on the upper rotating body 102. Each controller is composed of a processing device (processor) such as a CPU, a storage device such as a memory or a hard disk, an input / output interface for signal input / output with external devices, and realizes each function by executing a program stored in the storage device. In addition to the controllers shown in FIG. 2, the body of the hydraulic excavator 100 is equipped with controllers and the like according to the application and function.

[0021] The control controller 1 controls the driving of driven bodies such as the front work implement 103 of the work machine. An option device 3 is connected to the control controller 1 via a connection device 2. The option device 3 is a device required for a function (hereinafter, an option) to be added to the hydraulic excavator 100. The connection device 2 has a function of transmitting the name of the option device 3 to the control controller 1.

[0022] The option device 3 may be connected to one or more controllers other than the control controller 1. The option device is not limited to a controller or an electronic device, and may also be a device that cannot be electrically connected (e.g., an attachment, hydraulic equipment, etc.). An option device that cannot be electrically connected is attached to the vehicle body without using the connection device 2, and the name of the option device is transmitted to the information controller 4 by an 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 configured, for example, by a touch panel monitor installed in the driver's 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 an attachment / 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 an attached device acquisition function 20, a required device search function 21, and a configuration comparison function 22, and stores connected device name information 10, current configuration information 11, option required configuration information 12, option relationship information 13, an equipment configuration database 14, and option change instruction information 15.

[0025] The work procedure creation unit 4 b 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 a connection / detachment result determination function 60 and stores the connected device deviation warning 50.

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

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

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

[0030] FIG. 5 is a diagram showing an example of the inter-option relationship information 13. The inter-option relationship information 13 summarizes information that indicates the interrelationships between options. Some options function only on the premise that other options are functioning, and these other options are referred to as lower-level options. The example in FIG. 5 shows that the lower-level option of remote automation is remote control, the lower-level options of remote control are MC and obstacle detection, and the lower-level option of MC is MG.

[0031] Fig. 6 is a diagram showing an example of the equipment configuration database 14. Information on the equipment required by each option is compiled in the equipment configuration database 14. The example of Fig. 6 shows that the equipment required by MG (option number 4) is an angle sensor and an IMU.

[0032] Fig. 7 is a diagram showing an example of the option necessary configuration information 12. Information on devices required by the change option is summarized in the option necessary configuration information 12. The example of Fig. 7 shows that the devices required by the change option are an angle sensor and an IMU.

[0033] 8 is a diagram showing a method for determining a device to be attached or detached, and will be described in detail later.

[0034] 9 is a diagram showing an example of the attachment / detachment target device information 16. In this example, it is shown that the angle sensor and the IMU are to be attached, and the LiDAR is not to be attached / detached.

[0035] 10 is a diagram showing an example of the interrelationship between change options and sub-options. In this example, the interrelationship between change options and sub-options is represented by a tree diagram 33. The change option "remote control" is placed at the apex of the tree diagram 33, with "MC" and "obstacle detection", which are sub-options of "remote control", placed directly below it, and "MG", which is a sub-option of "MC", placed directly below "MC".

[0036] 11 is a diagram showing an example of device priority information 30. The device priority information 30 summarizes information indicating the order in which devices required for change options are attached and detached. The example of FIG. 11 shows that the order in which devices are attached when adding "remote control" is the angle sensor, IMU, and GNSS, and the order in which devices are removed when deleting "remote control" is the GNSS receiver, IMU, and angle sensor.

[0037] Fig. 12 is a diagram showing an example of an installation / removal procedure 32. The installation / removal procedure 32 is obtained by arranging the work methods for the devices to be installed / removed, extracted from the work manual 31, according to the device priority information 30. In the example of Fig. 12, the work methods are arranged in the order of the angle sensor, IMU, and GNSS receiver.

[0038] 13 is a diagram showing an example of a connected device deviation warning 50. The connected device deviation warning 50 is displayed on the display device 6 when a device other than the device to be removed is removed. The connected device deviation warning 50 includes a procedure for returning the erroneously removed device to its state before removal.

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

[0040] FIG. 14 is a flowchart showing the overall processing of the option 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, the option device that needs to be attached or detached for the changed option (hereinafter referred to as the attachment / detachment target device) is determined (step S102). The processing 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, an attachment / detachment procedure 32 is created (step S103). The process of step S103 is performed by the procedure creation unit 4b (shown in FIG. 2). The details of step S103 will be described later.

[0044] Following step S103, the actual attachment / detachment work by the worker is monitored to determine whether it deviates from the attachment / detachment work procedure 32 (step S104), and the flow ends. The processing of step S104 is performed by the deviation determination unit 4c (shown in FIG. 2). The details of step S104 will be described later.

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

[0046] First, current configuration information 11 is generated (step S201). Specifically, first, the names (connected device name information 10) of devices currently connected to the vehicle body (hereinafter referred to as connected devices) are queried. For example, if the connected device is a controller, the controller name is obtained directly. On the other hand, if 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 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, the optional necessary configuration information 12 is generated (step S202). Details of step S202 will be described with reference to FIG.

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

[0049] Following step S301, an option is extracted from the inter-option relationship information 13 (step S302), and it is determined whether or not it matches the changed option (step S303). If the determination result in step S303 is NO, the process returns to step S302.

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

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

[0052] Following step S306, the list of necessary devices extracted in step S306 is saved as the optional necessary configuration information 12 (step S307), and the flow ends.

[0053] 15, after step S202, the attachment / detachment target device information 16 is generated (step S203), and the flow ends. Details of step S203 will be described with reference to FIG.

[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 required option configuration information 12 to determine whether each device is a device to be removed or not according to the determination method shown in Figure 8 (step S403). In Figure 8, "◯" indicates that the device to be determined is installed, and "X" indicates that the device to be determined is not installed, and there are four combinations of the status in the current configuration information 11 and the status in the required option configuration information 12. The determination result "Installed" indicates that the device is to be installed, "Removed" indicates that the device is to be removed, and "-" indicates that the device is not to be removed or not installed or removed. Taking pattern 3 as an example, the status of the device to be determined in the current configuration information 11 is not installed, but the status of the device to be determined in the required option configuration information 12 is installed, so the determination result is "Installed," indicating that the device is to be installed or not.

[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 Figure 9, the angle sensor and IMU are to be attached, and the LiDAR is not to be attached / detached.

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

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

[0060] First, the inter-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, the priority of the change option and its subordinate options is determined (step S604). Details of step S604 will be described with reference to FIG.

[0064] First, an option is extracted from the inter-option relationship information 13 (step S701), and it is determined whether or not it matches the changed option (step S702). If the determination result in step S702 is NO, the process returns to step S701.

[0065] If the determination result in step S702 is YES, the lower level options of the changed option are extracted from the inter-option relationship information 13 (step S703), and it is determined whether extraction of all the lower level options has been completed (step S704). If the determination result in step S702 is NO, the process returns to step S703.

[0066] If the determination result in step S704 is YES, a tree diagram 33 (an example of which is shown in FIG. 10) showing the interrelationship between the change option and its subordinate options is created (step S705).

[0067] Following step S705, a breadth-first search is performed on the tree diagram 33 created in step S705, and a priority according to the hierarchical depth (hereinafter referred to as depth priority) is assigned 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" represents the depth priority. When a change option located at the top of the tree diagram 33 is to be added, it must be added in order from the option with the largest depth priority value. When a change option located at the top of the tree diagram 33 is to be deleted, it must be deleted in order from the option with the smallest depth priority value.

[0068] Following step S706, a priority within the same hierarchy (hereinafter referred to as breadth priority) is assigned to each option in the tree diagram 33 (step S707), and the flow ends. In the example of FIG. 10, taking the priority assigned to an option as "PRI:1-(i)" as an example, the "(i)" part represents breadth priority. Breadth priority is assigned, for example, by referencing the option number in the inter-option relationship information 13, starting with 1, in ascending order of option number. Note that there are no particular restrictions on how breadth priority is assigned, as long as there are no identical breadth priorities within the same hierarchy. When comparing option priorities, depth priority takes precedence over breadth priority.

[0069] 19 , following step S604, the priority of the required devices is determined for each option (step S605). Here, the required devices are linked to the priority of each option determined in step S604 in the order in which they are registered in the device configuration database 14.

[0070] Following step S605, the priorities of the necessary devices determined in step S605 are saved as device priority information 30 (step S606), and the flow ends.

[0071] 18, after step S501, the attachment / detachment procedure 32 is created (step S502), and the flow ends. Details of step S502 will be described with reference to FIG.

[0072] First, the attachment / detachment target device information 16 is read (step S801).

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

[0074] Following step S802, the operation manual 31 is read (step S803). The operation manual 31 summarizes information on specific installation / removal procedures for each device and setup procedures after installation (hereinafter referred to as the operation method).

[0075] Following step S803, the order in which the devices to be removed are attached and detached is determined in accordance with the device priority information 30 (step S804).

[0076] Following step S804, an installation / removal procedure 32 is created by linking the operation manual 31 with the installation / removal order of the target devices determined in step S804 (step S805).

[0077] Following step S805, the mounting / removal procedure 32 created in step S804 is saved (step S806), and the flow ends.

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

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

[0080] Following step S901, the next device to be removed and the work method are displayed based on the removal and installation work procedure 32 (step S902).

[0081] Following step S902, current configuration information 11 is generated (step S903).

[0082] Following step S903, the current configuration information 11 generated in step S902 is compared with the previously generated current configuration information 11 to extract a differential device (step S904). For example, if an optional monitor is newly connected, the optional monitor is extracted as a differential device.

[0083] Following step S904, it is determined whether or not there is a differential device (step S905). If the determination result in step S905 is NO, the process returns to step S903.

[0084] If the determination result in step S905 is YES, the next device to be attached / detached is compared with the differential device acquired in step S904 (step S906), and it is determined whether the two match (step S907). For example, if the next device to be attached / detached is a GNSS receiver, but an optional monitor is extracted as the differential device, the determination result in step S907 is NO.

[0085] If the determination result in step S907 is NO, a connected device deviation warning 50 is created and output to the display device 6 (step S908). In the above-mentioned specific example, the removal procedure for the erroneously installed optional monitor is displayed item by item in order, as shown in Figure 13. The removal procedure may be displayed in its entirety on the display device 6, or only a portion of it may be displayed.

[0086] Following step 908, or if the determination result in step 907 is YES, it is determined whether or not the attachment and detachment of all the target devices has been completed (step S909). In the specific example described above, the attachment of at least the GNSS receiver has not been completed, so 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 the determination result is YES, the flow ends.

[0088] (Summary) In this embodiment, in the optional device attachment / detachment support system 200 having a controller 4 that controls a function of supporting the attachment / detachment work of optional devices 3 to / from the work machine 100, the controller 4 has an attachment / detachment target determination unit 4a that determines the attachment / detachment target device, which is the optional device 3 to be attached or detached, a work procedure creation unit 4b that creates an attachment / detachment work procedure 32 for the optional devices to be attached or detached based on the interrelationships between a plurality of optional devices 3, and a deviation determination unit 4c that outputs a connected device deviation warning 50 when the optional device 3 that is instructed to be attached or detached next in the attachment / detachment work procedure 32 is different from the newly attached or detached optional device 3.

[0089] According to this embodiment configured as described above, an installation / removal procedure 32 for devices to be installed / removed is presented to the worker in an order that takes into consideration the interrelationships between a plurality of option devices 3, and a warning is issued if work is performed that deviates from the installation / removal procedure 32. This reduces the effort required for installing / removing option devices 3 on the work machine 100 while suppressing work errors, and makes it possible to guarantee the operation of any options newly added to the work machine 100.

[0090] The option device attachment and removal support system 200 in this embodiment also includes an input device 6 for indicating a change option, which is an option to be added or deleted, and the controller 4 generates, by the attachment and removal target determination unit 4a, current configuration information 11 representing the configuration of the option devices 3 currently attached to the work machine 100, and generates option required configuration information 12 representing the configuration of the option devices 3 required by the change option indicated by the input device 6 based on a device configuration database 14 representing the configuration of the option devices 3 required for each option and option relationship information 13 representing the interrelationships between a plurality of option devices 3, and determines the device to be attached or removed by extracting the difference between the option required configuration information 12 and the current configuration information 11. This makes it possible for the worker to identify only the option devices 3 that require attachment and removal work.

[0091] Furthermore, the controller 4 in this embodiment uses the work procedure creation unit 4b to generate device priority information 30 indicating the installation and removal order of the option devices 3 required by the change option specified by the input device 6, based on the device configuration database 14 and the option relationship information 13, extracts the work methods for the devices to be installed and removed from the work manual 31 in which the work methods for each option device 3 are described, and creates an installation and removal work procedure 32 by arranging the work methods for the devices to be installed and removed in accordance with the device priority information 30. This eliminates the need for the worker to refer to the work manual 31, making it possible to reduce the effort required for the installation and removal work.

[0092] Furthermore, the controller 4 in this embodiment notifies the operator to return the incorrectly connected or disconnected option device 3 to the state before the connection or disconnection by using the connected device deviation warning 50. This allows the operator to quickly correct the operational error.
