[0033] Hereinafter, the implementation mode will be described based on the drawings. In the following description, the same reference numerals are assigned to the same components. The names and functions of these components are also the same. Therefore, detailed descriptions of these components will not be repeated. In addition, it is originally planned to use the structures in the implementation mode in appropriate combinations. In addition, there are cases where some components are not used.

[0034] Hereinafter, a construction machine system including a server device, a construction machine, and a terminal device will be described with reference to the drawings. Hereinafter, as the construction machine, a hydraulic excavator as a construction vehicle will be described as an example. In addition, in the following description, "rear" and "right" are terms based on an operator sitting in the driver's seat of the construction vehicle.

[0035] <A. System configuration>

[0036] Figure 1 This is a diagram showing the schematic configuration of the construction machine system according to the implementation mode.

[0037] As Figure 1 shown, the construction machine system 1000 includes a plurality of construction vehicles 1, 1A, a server device 2, and a terminal device 3. It should be noted that the number of construction vehicles is not limited to 2. The number of terminal devices 3 is also not limited to 1.

[0038] The terminal device 3 is a client device. The terminal device 3 is a portable device. Typically, the terminal device 3 is a tablet terminal. The terminal device 3 is used by maintenance personnel who repair and maintain construction machinery. The terminal device 3 functions as an auxiliary device (fault diagnosis auxiliary device) for the maintenance personnel to investigate the cause of a fault in the construction machinery. For example, when a fault occurs in the work vehicle 1, the maintenance personnel bring the terminal device 3 to the location of the work vehicle 1 and operate the terminal device 3 at that location.

[0039] The terminal device 3 is equipped with a browser. The terminal device 3 displays a web page provided by the server device 2. Various screens including moving images and still images described later are typically provided in the form of web pages.

[0040] The work vehicles 1, 1A and the terminal device 3 are connected to the server device 2 via the network 5 in a communicable manner. In Figure 1 this example, the work vehicle 1 and the terminal device 3 are respectively connected to the network 5 via a base station 4 in the service area where they are located. The work vehicle 1A is connected to the network 5 via a base station 4A in the service area where the work vehicle 1A is located.

[0041] The communication between the work vehicles 1, 1A and the terminal device 3 and the server device 2 can use, for example, the 3G communication standard, the 4G communication standard, the communication standard related to LTE (Long Term Evolution, also known as 3.9G or Pre-4G), or the Wimax (registered trademark) communication standard. In addition, the work vehicles 1, 1A and the terminal device 3 can also communicate with the server device 2 using a satellite link.

[0042] It should be noted that the terminal device 3 is an example of the "terminal device" in the present invention. The server device 2 is an example of the "server device" in the present invention. The work vehicle 1 is an example of the "construction machinery" in the present invention. The work vehicle 1A is an example of the "other construction machinery" in the present invention.

[0043] <B. User Interface>

[0044] The user interface displayed on the terminal device 3 will be described.

[0045] (b1. Example of operations until the display of the disassembly steps)

[0046] Figure 2 A screen displayed on the terminal device 3 is shown.

[0047] As Figure 2As shown, screen 320 shows a state when the maintenance personnel performs input operation to the input box etc. displayed on the home screen. It should be noted that the home screen is a screen displayed on the terminal device 3 when the application installed in the terminal device 3 is executed.

[0048] (1) Screen description

[0049] The screen 320 includes a plurality of objects 3101 to 3106 and a plurality of areas 3200 , 3300 , 3400 , and 3500 .

[0050] Object 3101 is an icon for displaying the home screen. Object 3102 is an icon selected by maintenance personnel when performing fault diagnosis. Object 3103 is an icon for displaying the current position of the working machine on a map. Object 3104 is an icon for displaying the maintenance history of the working machine. Object 3105 is an icon for displaying the factory manual. Object 3106 is an icon for displaying the instruction manual.

[0051] Area 3200 has information about the target work machine (in Figure 1 In the case of the work vehicle 1), the machine type input column 3201, the model input column 3202, the serial number input column 3203, the customer name input column 3204, the registration date input column 3205 and the object 3206.

[0052] Area 3300 includes a fault location input field 3301, a fault phenomenon input field 3302, and a fault code input field 3303. The maintenance personnel can input in the fault location input field 3301 and the fault phenomenon input field 3302 through a pull-down menu.

[0053] Area 3400 is for carrying out operations with the target machine (in Figure 1 In the case of the work vehicle 1), the area 3400 automatically displays the fault code, intervention level, error name, cumulative number of occurrences of the error, maximum temperature, minimum temperature, occurrence SMR (Service Meter Reading: cumulative operation time) and the year, month and day of occurrence. The fault code shown in area 3400 (in Figure 2 In the example "CA731"), it is configured to be selectable through operations performed by maintenance personnel.

[0054] Area 3500 automatically displays information on tools used and information on equipment to be repaired.

[0055] (2) Status evolution on the home page

[0056] After the maintenance personnel inputs data into the input fields 3201, 3202, and 3203, if object 3206 is selected, the terminal device 3 automatically inputs data into the input fields 3204 and 3205 as shown in the figure. If object 3206 is selected, the terminal device 3 displays the illustrated fault (error) in the area 3400.

[0057] Specifically, when receiving input to the input fields 3201, 3202, and 3203, the terminal device 3 transmits the input data to the server device 2. The server device 2 extracts the customer name, registration date, and information related to the failure based on the data received from the terminal device 3. The server device 2 notifies the terminal device 3 of the extracted customer name, registration date, and information related to the failure.

[0058] In the above manner, input (display) into input fields 3201 to 3205 and display in area 3400 as shown in the figure are realized.

[0059] Next, if the maintenance personnel selects the fault code shown in area 3400 (in Figure 2 In the example of "CA731", the selected fault code is automatically input into the input field 3303 of the area 3300. If the fault code shown in the area 3400 is selected, the terminal device 3 displays the information of the tools used and the information of the maintenance equipment associated with the fault code in the area 3500. Typically, the terminal device 3 obtains the information of the tools used and the information of the maintenance equipment from the server device 2 based on the fault code.

[0060] It should be noted that the so-called maintenance equipment refers to equipment used for maintenance of a part (component) in a state where it can be maintained using a tool. For example, the maintenance equipment is a device connected to each other between wire harnesses to set a branch path from the wire harness.

[0061] In the above manner, the input field 3303 in the illustrated area 3300 and the display in the area 3500 are realized.

[0062] However, if Figure 2 As shown in the example of , the terminal device 3 acquires information related to the faults that occurred in the target working machine in the past by communicating with the server device 2, and displays the acquired information in the area 3400. Then, the maintenance personnel selects the fault code displayed in the area 3400, and the fault code is input into the input field 3303. However, the method of inputting the fault code is not limited to this. For example, the following two methods can also be used.

[0063] As a first method, when the maintenance personnel can determine the fault code based on hearing from the operator of the work vehicle 1, the maintenance personnel does not input into the input fields 3201 to 3203 of the area 3200, but only inputs the fault code into the input field 3303 of the area 3300. Alternatively, when the maintenance personnel reproduces the fault by operating the work vehicle 1, and when the maintenance personnel can determine the fault code, the maintenance personnel does not input into the input fields 3201 to 3203 of the area 3200, but only inputs the fault code into the input field 3303 of the area 3300. Next, based on Figure 3 The second method will be described.

[0064] Figure 3 This is a diagram for explaining how to enter a fault code.

[0065] like Figure 3 As shown, screen 330 shows a state where the maintenance personnel performs input operation on the input box displayed on the home screen. The maintenance personnel performs input to input fields 3301 and 3302 of area 3300 based on the result of listening to the operator of work vehicle 1, for example.

[0066] When input is made to the input fields 3301 and 3302, the terminal device 3 displays the fault code determined based on the input in the input field 3303. It should be noted that the fault code can be determined by either the server device 2 or the terminal device 3.

[0067] (3) Evolution of the screen from the home page

[0068] Figure 4 This is a diagram showing a screen displayed when an object 3102 is selected in a state where a trouble code is input in an input field 3303 on the home screen.

[0069] like Figure 4 As shown, the screen 340 has an area 3600 and an area 3700 .

[0070] Area 3600 includes selectable objects 3601. When the maintenance personnel selects object 3601, the terminal device 3 switches to a mode for displaying augmented reality. In this mode, when the maintenance personnel directs the back side (the side opposite to the display and provided with a camera) of the terminal device 3 toward the work vehicle 1, the internal structure is displayed overlapping with the work vehicle 1.

[0071] The terminal device 3 displays a troubleshooting manual 3701 based on the trouble code input in the input field 3303 in the area 3700. The troubleshooting manual 3701 may be acquired from the server device 2 by the terminal device 3 transmitting the trouble code to the server device 2, or may be stored in the terminal device 3 in advance.

[0072] The troubleshooting manual 3701 includes description columns 3710, 3720, 3730, and 3740. The troubleshooting manual 3701 is configured to be scrollable at least in the vertical direction.

[0073] The record column 3710 records the serial numbers in the fault response manual 3701. Each serial number can be selected by a maintenance person. The record column 3720 records multiple candidates for the multiple parts (e.g., components) of the working machine that are estimated to be the cause of the fault for each serial number. In this way, the maintenance person selects a serial number on the terminal device 3, thereby being able to select one part from the multiple candidates.

[0074] The trouble diagnosis procedure, measurement location, standard (value) and remarks of the candidate (part) are described for each of the serial numbers in the description column 3730. The diagnosis result and measures are described for each of the serial numbers in the description column 3740.

[0075] As described above, the terminal device 3 displays a plurality of candidates estimated as the cause of the failure of the work vehicle 1 among a plurality of parts of the work vehicle 1 on the display of the terminal device 3. The terminal device 3 receives an input for selecting one part from the plurality of candidates.

[0076] When receiving an input for selecting one part from a plurality of candidates, the terminal device 3 changes the display screen from the screen 340 to a screen corresponding to the selected part.

[0077] Figure 5 1 is a diagram showing a screen displayed when the swing lock switch is selected from a plurality of candidates estimated as the cause of the failure by selecting the consecutive number "3" on the screen 340.

[0078] like Figure 5 As shown, screen 350 includes area 3800 and area 3900. Terminal device 3 displays a plurality of objects 3801 to 3805 in area 3800. Terminal device 3 displays a fault response manual 3901 related to a "swing lock switch" as an example of a selected part in area 3900. Fault response manual 3901 is a portion extracted from fault response manual 3701. Therefore, fault response manual 3901 includes fault diagnosis steps, measurement locations, benchmarks (values), and remarks for the swing lock switch. In addition, fault response manual 3901 includes information on diagnostic results and measures.

[0079] When the maintenance worker selects the object 3801 , the terminal device 3 displays a dynamic image showing “disassembly steps of disassembling the work vehicle 1 until the swing lock switch as the selected part appears” on the display of the terminal device 3 .

[0080] Typically, when the object 3801 is selected, the terminal device 3 acquires (downloads) the dynamic image data showing the decomposition steps from the server device 2. When the maintenance personnel inputs the acquired dynamic image data to be played to the terminal device 3, the terminal device 3 plays the dynamic image data. As a result, the dynamic image showing the decomposition steps is displayed on the display.

[0081] When the maintenance worker selects object 3802, terminal device 3 displays a plurality of still images showing “disassembly steps of disassembling work vehicle 1 until the swing lock switch as the selected part appears” on the display of terminal device 3. Typically, terminal device 3 displays still images one by one.

[0082] It should be noted that object 3801 is an example of a "first object" in the present invention, and object 3802 is an example of a "second object" in the present invention.

[0083] (b2. Display of decomposition steps based on animation)

[0084] Hereinafter, the disassembly procedure will be described by taking as an example a case where the selected portion is a specific component in the rear cover.

[0085] Figure 6 It is a diagram showing a display example of a moving image of the rear cover and the disassembly process inside the rear cover.

[0086] like Figure 6 As shown, the terminal device 3 displays a screen 860 including a dynamic image 861 showing the decomposition steps on the display. The maintenance personnel confirms the dynamic image, so that the maintenance personnel can easily understand the decomposition steps. Therefore, the maintenance personnel can quickly confirm the state of the part estimated to be the cause of the failure of the work vehicle 1. Furthermore, the maintenance personnel can quickly perform the repair or replacement work of the part estimated to be the cause of the failure of the work vehicle 1.

[0087] Screen 860 also includes text information 862 showing the decomposition steps in time series. Typically, text information 862 consists of text showing each of the multiple decomposition steps, and each text is numbered according to the decomposition order and arranged in the decomposition order. With such a display, maintenance personnel can easily understand the overall process of the decomposition work.

[0088] When the terminal device 3 starts playing the dynamic image based on the operation performed by the maintenance personnel, the text corresponding to the displayed scene is displayed in a style different from other texts. Since the scene of removing the cover is played in the partial screen of the figure, the terminal device 3 highlights the text "1. Remove the cover". Based on such a display, the maintenance personnel can easily understand what level of steps (operation procedures) are required afterwards.

[0089] In addition, the terminal device 3 displays the text 863 corresponding to the displayed scene overlaid on the dynamic image. Since the scene of removing the cover is played in the partial screen of the figure, the terminal device 3 displays the text "1. Remove the cover" overlaid on the dynamic image. According to this configuration, the maintenance personnel can more clearly understand which step the scene of the dynamic image is compared with the case where the text is not overlaid on the dynamic image.

[0090] It should be noted that the terminal device 3 can stop, replay, rewind, etc. the playback of the moving image at any timing. Thus, the maintenance personnel can fully check the desired part when they want to check.

[0091] (b3. Display of decomposition steps based on still images)

[0092] The following description will take as an example the disassembly procedure in a case where the selected part is a specific component in the right console.

[0093] Figure 7 It is a diagram showing a display example of the first figure (still image) showing the disassembly procedure of the right console.

[0094] like Figure 7 As shown, the terminal device 3 displays a screen 871 including an image 8710 of the right console on the display. The screen 871 also includes an object 8712 and explanation content 8713 about the decomposition method.

[0095] In image 8710, the part to be removed (in this example, the handrail) is displayed in a striking manner. For example, the handrail is displayed in a different color (for example, red) than the original one. Thus, the maintenance personnel can immediately understand the part to be removed in the partial picture.

[0096] In addition, image 8710 includes an image indicating the position of parts associated with the removal of the handrail. In the case of this example, the bolts that fix the handrail are displayed with leads and text in image 8710. Based on such a display, maintenance personnel can easily grasp the position of the parts used to remove the handrail. In addition, like the handrail, it is preferred that the terminal device 3 displays the bolts in a color different from the original color.

[0097] In addition, an image of an arrow indicating the direction in which the handrail is to be removed is included in image 8710. Based on this display, the maintenance personnel can easily understand the direction in which the handrail is to be removed (moving direction).

[0098] The maintenance personnel can more accurately understand the work contents by checking the image 8710 and the description content 8713. Typically, the description content 8713 includes the component names shown in the image 8710 in text (in this example, "handrail" and "bolt"). In addition, the description content 8713 may also include information not shown in the image 8710 (in this example, "M8 width across 6 mm").

[0099] After removing the handrail, the maintenance personnel selects the object 8712, thereby enabling the display screen of the terminal device 3 to transition from the screen 871 to the next screen.

[0100] Figure 8 It is a diagram showing a display example of the second figure (still image) showing the disassembly procedure of the right console.

[0101] like Figure 8 As shown, the terminal device 3 displays a screen 872 including an image 8720 of the right console after the armrest is removed on the display. The screen 872 also includes objects 8721 and 8722 and an explanation content 8723 on the disassembly method.

[0102] In image 8720, the component to be removed (in this example, the fuel dial) is displayed in a striking manner. Thus, the maintenance personnel can immediately grasp the component to be removed in the partial picture.

[0103] In addition, an image of an arrow indicating the direction in which the fuel dial is to be removed is included in image 8720. Based on this display, the maintenance personnel can easily understand the direction in which the fuel dial is to be removed.

[0104] Maintenance personnel confirm the image 8720 and the description content 8723 so as to understand the content of the work more accurately.

[0105] After removing the fuel dial, the maintenance personnel selects object 8722 to change the display screen of the terminal device 3 from screen 872 to the next screen. It should be noted that the maintenance personnel selects object 8721 to return the display screen of the terminal device 3 from screen 872 to the previous screen 871.

[0106] Fig. 9 It is a diagram showing a display example of the third figure (still image) showing the disassembly procedure of the right console.

[0107] like Fig. 9 As shown, the terminal device 3 displays a screen 873 including an image 8730 of the right console after the fuel dial is removed on the display. The screen 873 also includes objects 8731 and 8732, explanation content 8733 on the disassembly method, and an image 8734 showing precautions.

[0108] In image 8730, the components to be removed (in this example, the plate for fixing the shield) are displayed in a striking manner. Thus, the maintenance personnel can immediately grasp the components to be removed in the partial picture.

[0109] The maintenance personnel can more accurately understand the operation content by checking the image 8730 and the explanation content 8733. In addition, the maintenance personnel can perform appropriate operations by checking the image 8734 showing the precautions. It should be noted that the image 8734 typically includes an image of a main part enlarged and text showing the precautions.

[0110] After rolling up the hood in the cab of the work vehicle 1, the maintenance personnel selects object 8732, so that the display screen of the terminal device 3 changes from screen 873 to the next screen. It should be noted that the maintenance personnel selects object 8731, so that the display screen of the terminal device 3 can return from screen 873 to the previous screen 872.

[0111] Fig.10 A diagram showing a display example of the final (fourth) still image showing the disassembly procedure of the right console.

[0112] like Fig.10 As shown, the terminal device 3 displays a screen 874 including an image 8740 of the right console after the cover is rolled up on the display. The screen 874 also includes an object 8741 and an explanation content 8743 on the decomposition method. The image 8740 includes main part enlarged images 8744 and 8745.

[0113] In image 8740, the component to be removed (in this example, the cover) is displayed in a striking manner. Thus, the maintenance personnel can immediately grasp the component to be removed in the partial picture.

[0114] The maintenance personnel can more accurately understand the operation contents by checking the image 8740 and the explanation contents 8743. In addition, the maintenance personnel can perform appropriate operations by checking the main part enlarged images 8744 and 8745.

[0115] It should be noted that the maintenance personnel can return the display screen of the terminal device 3 from the screen 874 to the previous screen 873 by selecting the object 8741 .

[0116] As described above, the terminal device 3 displays on the display a plurality of still images showing the disassembly steps of disassembling the work vehicle 1 until the selected part appears. The maintenance personnel confirms the plurality of still images, so that the maintenance personnel can easily grasp the disassembly steps. Therefore, the maintenance personnel can quickly confirm the state of the part estimated to be the cause of the failure of the work vehicle 1. Furthermore, the maintenance personnel can quickly perform the repair or replacement work of the part estimated to be the cause of the failure of the work vehicle 1.

[0117] (b4. Display of contents other than decomposition steps)

[0118] (1) 3D layout diagram

[0119] Maintenance personnel selection Figure 5 When the object 3803 shown in the figure is selected, the terminal device 3 displays the three-dimensional configuration diagram of the swing lock switch as the selected part on the display of the terminal device 3. The terminal device 3 displays a diagram showing the swing lock switch and the surrounding parts in three dimensions. Typically, when the object 3803 is selected, the terminal device 3 obtains the image data of the three-dimensional configuration diagram from the server device 2, and displays the three-dimensional configuration image on the display of the terminal device 3 based on the image data.

[0120] By displaying the three-dimensional arrangement diagram of the swing lock switch, a maintenance worker can easily and three-dimensionally understand the position of the swing lock switch.

[0121] The maintenance worker designates a partial area of ​​the stereoscopic layout diagram, and the terminal device 3 displays an enlarged view (stereoscopic layout diagram) of the designated area. This allows the maintenance worker to check the stereoscopic layout diagram in more detail.

[0122] (2) Diagram of connecting pin

[0123] If the maintenance personnel selects object 3804, the terminal device 3 displays a diagram of the connection pin of the swing lock switch as the selected part on the display of the terminal device 3. Typically, if object 3804 is selected, the terminal device 3 acquires image data of the connection pin from the server device 2, and displays the diagram of the connection pin on the display of the terminal device 3 based on the image data.

[0124] By displaying the diagram of the connection pins, maintenance personnel can confirm the information of the pins, thereby enabling rapid fault diagnosis.

[0125] (3) Parts catalog

[0126] If the maintenance personnel select the object 3805, the terminal device 3 will display the parts catalog of the swing lock switch of the selected part on the display of the terminal device 3. It should be noted that the parts catalog includes a diagram of disassembling the swing lock switch into parts (bolts, nuts, springs,...), detailed information (model numbers, etc.) of each part, and so on. Typically, if the object 3805 is selected, the terminal device 3 obtains the image data of the parts catalog from the server device 2 and displays the diagram of the parts catalog on the display of the terminal device 3 based on the image data.

[0127] By displaying the parts catalog, the maintenance personnel can confirm the model numbers and so on of the various parts that make up the part they have selected. Therefore, the repair arrangement can be made quickly.

[0128] <C. Hardware Structure>

[0132] The memory 302 includes a ROM 3021 that stores data non-volatilely, a RAM 3022 that stores data generated by executing programs by the processor 301 or input data volatilely, and a flash memory 3023 that stores data non-volatilely. The components 301 to 306 are connected to each other via a data bus.

[0133] The touch screen 305 is composed of a display 3051 and a touch panel 3052. The antenna 307 is an antenna for the communication interface 303. The communication interface 303 performs, for example, a transmission process of sending data to the server device 2 and a reception process of receiving data sent from the server device 2. The touch screen 305 is a device for displaying various data and accepting operation inputs.

[0134] The processing in the terminal device 3 is implemented by various hardware and software executed by the processor 301. Such software is sometimes pre-stored in the flash memory 3023. In addition, there is a case where the software is stored in other storage media and circulated as a program product. Alternatively, there is a case where the software is provided in the form of a downloadable program product by an information provider connected to the so-called Internet. Such software is temporarily stored in the flash memory 3023 after being read from its storage medium by a reading device or downloaded via the communication interface 303. The software is read from the flash memory 3023 by the processor 301 and stored in the RAM 3021 in the form of an executable program. The processor 301 executes the program.

[0135] The components constituting the terminal device 3 shown in the figure are common components. Therefore, it can also be said that the main part of the present invention is the software stored in the memory 302 or the storage medium or the software that can be downloaded via the network. It should be noted that since the operation of each hardware of the terminal device 3 is well known, the detailed description will not be repeated.

The memory 202 typically includes a ROM 2021, a RAM 2022, and a HDD (Hard Disc) 2023. The reader / writer 206 reads various data including programs from a memory card 299 as a storage medium or writes data to the memory card 299.

[0140] The processor 201 executes the program stored in the memory 202. The RAM 2022 temporarily stores various programs, data generated by the processor 201 executing the program, and data input by the user. The ROM 2021 is a non-volatile storage medium, and typically stores BIOS (Basic Input Output System) and firmware. The HDD 2023 stores the OS (Operating System), various application programs, and the like.

[0141] Software such as programs stored in the memory 202 is also sometimes stored in a memory card, other storage media, and distributed as a program product. Alternatively, software may also be provided by an information provider connected to the so-called Internet in the form of a downloadable program product. Such software is temporarily stored in the RAM 2022 after being read from its storage medium by a memory card reader or other reading device, or downloaded via an interface. The software is read by the processor 201 from the RAM 2022 and then stored in the HDD 2023 in the form of an executable program. The processor 201 executes this program.

[0142] Each component of the server device 2 shown in this figure is a common component. Therefore, it can also be said that the main part of the present invention is the software stored in the memory 202, memory card, other storage media, or software that can be downloaded via a network.

[0143] It should be noted that the recording medium is not limited to DVD (Digital Versatile Disc)-ROM, CD (Compact Disc)-ROM, FD (Flexible Disk), or hard disk. For example, it may also be a magnetic tape, cassette tape, optical disc (MO (Magnetic Optical Disc) / MD (Mini Disc)), optical card, masked ROM, EPROM (Electronically Programmable Read-Only Memory), EEPROM (Electronically Erasable Programmable Read-Only Memory), flash ROM, or other semiconductor memories that fixedly store programs. In addition, the recording medium is a non-transitory medium that can be read by a computer for such programs and does not include transitory media such as transmission waves.

[0144] In addition, the program mentioned here not only includes a program that can be directly executed by the processor 201, but also includes a program in source code form, a compressed program, an encrypted program, etc.

[0145] It should be noted that the processor 201 is an example of the "processor of the server device" in the present invention.

[0146] <D. Functional Structure>

[0147] Fig.13This is a functional block diagram for explaining the functional configuration of each device constituting the working machine system 1000 .

[0148] like Fig.13 As shown, the working machine system 1000 includes a working vehicle 1 , a server device 2 , and a terminal device 3 .

[0149] (d1. Work vehicle 1)

[0150] The work vehicle 1 includes a control unit 151 and a communication unit 153 .

[0151] The control unit 151 controls the overall operation of the work vehicle 1. The control unit 151 corresponds to a controller (not shown) of the work vehicle 1. The communication unit 153 communicates with the server device 2 via a base station or the like.

[0152] When a failure occurs in the work vehicle 1 , the control unit 151 transmits a failure code associated with the occurred failure to the server device 2 using the communication unit 153 .

[0153] It should be noted that the work vehicle 1A (see Figure 1 ) also has the same structure as the work vehicle 1.

[0154] (d2. Server device 2)

[0155] The server device 2 includes a control unit 251 , a storage unit 252 , and a communication unit 253 .

[0156] The control unit 251 includes a ranking unit 2511. The processing of the ranking unit 2511 will be described later.

[0157] The storage unit 252 stores troubleshooting procedures, decomposition procedures, troubleshooting history, user manuals, and factory manuals in the form of digital data for each machine type and model. It should be noted that the storage unit 252 stores programs such as an operating system for operating the server device 2.

[0158] The control unit 251 controls the overall operation of the server device 2. The control unit 251 communicates with the work vehicle 1 (1A) via the communication unit 253. The control unit 251 obtains the fault code from the work vehicle 1 via the communication unit 253. The control unit 251 further communicates with the terminal device 3 via the communication unit 253. The data sent and received with the terminal device 3 will be described later.

[0159] It should be noted that the control unit 251 and Fig.12 More specifically, the processor 201 executes the program stored in the memory 202 to implement the control unit 251. The communication unit 253 and Fig.12 The storage unit 252 corresponds to the communication interface 203 in FIG. Fig.12 Corresponding to the memory 202 in.

[0160] (d3. Terminal device 3)

[0161] The terminal device 3 includes a control unit 351 , a storage unit 352 , a communication unit 353 , an input unit 354 , and a display unit 355 .

[0162] The control unit 351 controls the overall operation of the terminal device 3. The control unit 351 communicates with the server device 2 via the communication unit 353. The control unit 351 receives data input by a maintenance person via the input unit 354. The control unit 351 causes the display unit 355 to display various images.

[0163] It should be noted that the control unit 351 and Fig.11 More specifically, the processor 301 executes the program stored in the memory 302 to implement the control unit 351. The communication unit 353 and Fig.11 The storage unit 352 corresponds to the communication interface 303 in FIG. Fig.11 The input unit 354 corresponds to the memory 302 in FIG. Fig.11 The touch panel 3052 and the operation button 306 in FIG. 354 correspond to each other. Fig.11 Corresponding to the display 3051 in.

[0164] (d4.Data communication and display)

[0165] Next, data transmitted and received between the terminal device 3 and the server device 2 will be described.

[0166] In the terminal device 3, enter the state with the fault code in the input field 3303 (see Figure 2 ) under, if the maintenance personnel selects object 3102, the terminal device 3 sends the fault code to the server device 2.

[0167] When the server device 2 receives the fault code from the terminal device 3, it sends a fault response manual based on the fault code to the terminal device 3. As described above, the fault response manual includes the fault diagnosis steps. When the terminal device 3 receives the fault response manual, Figure 4 As shown in the example of screen 340, the display unit 355 displays the troubleshooting manual.

[0168] If the maintenance personnel selects a consecutive number in the fault response manual (in Figure 4In the example of the example of the serial number in the description column 3710), the selected number is notified to the server device 2. When the server device 2 receives the notification of the number from the terminal device 3, it sends the fault response manual related to the component (selected part) corresponding to the number to the terminal device 3. As described above, the fault response manual includes the fault diagnosis steps.

[0169] Terminal device 3 Figure 5 As shown in the example of screen 350, a screen including the following contents is displayed: a troubleshooting manual related to the selected part (in Figure 5 In the example, it is a troubleshooting manual 3901); an object 3801 for displaying a dynamic image showing the decomposition steps; an object 3802 for displaying a still image showing the decomposition steps; an object 3803 for displaying a three-dimensional configuration diagram; an object 3804 for displaying a connecting pin diagram; and an object 3805 for displaying a parts catalog.

[0170] When the maintenance worker selects object 3801, the terminal device 3 requests the server device 2 to send a dynamic image showing "the disassembly steps of disassembling the working machine until the selected part appears". The server device 2 sends the dynamic image showing the disassembly steps to the terminal device 3 in accordance with the request from the terminal device 3. When the terminal device 3 obtains the dynamic image from the server device, it plays the dynamic image based on the playback instruction of the maintenance worker.

[0171] When the maintenance worker selects object 3802, the terminal device 3 requests the server device 2 to send a plurality of still images showing "the disassembly steps of disassembling the working machine until the selected part appears". The server device 2 sends a plurality of still images showing the disassembly steps to the terminal device 3 in accordance with the request from the terminal device 3. When the terminal device 3 obtains a plurality of still images from the server device, it displays the still images on the display unit 355.

[0172] (d5. Order of precedence)

[0173] Refer again Figure 4 The terminal device 3 displays a plurality of candidates estimated as the cause of the failure of the work vehicle 1 among a plurality of parts of the work vehicle 1. In this example, a case where the terminal device 3 sequentially displays a plurality of candidates together with consecutive numbers is described.

[0174] However, the display method is not limited to this, and the sequence assigning unit 2511 (see Fig.13 ) Display each candidate by assigning a priority to each candidate.

[0175] In the server device 2, for multiple candidates, rankings are established in descending order of the probability of the cause of failure. Typically, the server device 2 determines the rankings based on the failure information of other construction machines (e.g., construction vehicle 1A) different from the construction vehicle 1 during a preset period.

[0176] It should be noted that the other construction machines are preferably of the same model as the construction vehicle 1. More preferably, the other construction machines are of the same model and the same type as the construction vehicle 1.

[0177] When the terminal device 3 displays multiple candidates based on the received failure response manual 3701 from the server device, the rankings of the multiple candidates are further displayed. For example, the terminal device 3 displays the priority rankings in the entry column 3720. According to such a display, the maintenance personnel can confirm the components shown in the diagnosis screen of the terminal device 3 in order of ranking, thereby quickly determining the failure location.

[0178] It should be noted that the server device 2 can also send a diagnosis screen in a state where multiple candidates are sorted in order of ranking to the terminal device 3. In this case, on the terminal device 3, the multiple candidates are displayed in order from the top, for example. According to such a display, the maintenance personnel can immediately grasp the order of the failure probabilities for the multiple candidates. Therefore, compared with the case where the candidates are not sorted, the maintenance personnel can quickly determine the failure location.

[0179] <E. Processing Flow>

[0180] Fig.14 It is a timing diagram for explaining the processing flow in the construction machine system 1000.

[0181] As Fig.14 shown, in the timing SQ1, if the construction vehicle 1 breaks down, the construction vehicle 1 sends a failure code to the server device 2. It should be noted that, as shown in the timing SQ2, the server device 2 can also notify the failure code to the terminal device 3.

[0182] In the timing SQ3, a failure code is sent from the terminal device 3 to the server device 2. In the timing SQ4, the server device 2 sends a failure response manual (e.g., Figure 4 the failure response manual 3701) corresponding to the received failure code to the terminal device 3.

[0183] In the timing SQ5, the terminal device 3 notifies the server device 2 of the part (e.g., the "swing lock switch" of No. 3) selected by the maintenance personnel using the number. In the timing SQ6, the server device 2 sends a failure response manual (e.g., Figure 5 the failure response manual 3901) of the selected part to the terminal device 3.

[0184] In timing SQ7, based on the icon selection operation by the maintenance staff on the screen (e.g., Figure 5 the screen 350) that displays the fault response manual for the selected part, the terminal device 3 requests the server device 2 to send a dynamic image or multiple still images showing "the disassembly steps for disassembling the work vehicle 1 until the selected part appears".

[0185] In timing SQ8, the server device 2 sends a dynamic image or multiple still images showing "the disassembly steps for disassembling the work vehicle 1 until the selected part appears" to the terminal device 3 according to the request from the terminal device 3.

[0186] Thereby, in the terminal device 3, the maintenance staff can confirm the dynamic image or multiple still images.

[0187] Fig.15 It is a flowchart for explaining the processing flow in the terminal device 3.

[0188] As Fig.15 shown, the terminal device 3 accepts the input of the fault code by the maintenance staff in step S1. It should be noted that the input of the fault code by the maintenance staff is not necessary.

[0189] In step S2, the terminal device 3 sends the fault code to the server device 2 based on the operation performed by the maintenance staff. In step S3, the terminal device 3 receives the fault response manual containing the fault diagnosis steps from the server device 2. In step S4, the terminal device 3 displays the fault response manual (see Figure 4 ).

[0190] In step S5, the terminal device 3 accepts the operation of the maintenance staff to select one part from multiple candidates (parts). For example, in Figure 4 the example, the terminal device 3 accepts the operation of selecting the number "3" etc. in the entry column 3710. In step S6, the terminal device 3 sends the number of the selected part to the server device 2.

[0191] In step S7, the terminal device 3 obtains an image (animation or multiple still images) showing "the disassembly steps for disassembling the work vehicle 1 until the selected part appears" from the server device 2. In step S8, the terminal device 3 displays the obtained disassembly steps.

[0192] <F. Summary>

[0193] (f1. Terminal device)

[0194] The actions in multiple partial screens are extracted from the actions of the above terminal device 3 as follows.

[0195] (1) The terminal device 3 includes the processor 301 (control unit 351 ) and the display 3051 (display unit 355 ).

[0196] Processor 301 causes display 3051 to display candidates estimated as the cause of failure of work vehicle 1 among a plurality of parts of work vehicle 1. Processor 301 causes display 3051 to further display a dynamic image or a plurality of still images showing the disassembly steps of disassembling work vehicle 1 until the candidate parts appear.

[0197] This allows the maintenance personnel to quickly check the status of the portion estimated to be the cause of the failure of the work vehicle 1 .

[0198] (2) The terminal device 3 further includes a touch panel 3052 (input unit 354) for accepting input based on user operation.

[0199] The processor 301 causes the display 3051 to display a plurality of candidates (a plurality of different candidates) estimated as the cause of the failure of the work vehicle 1 among the plurality of parts of the work vehicle 1. When the touch panel 3052 receives an input for selecting one part from the plurality of candidates, the processor 301 causes the display 3051 to further display a dynamic image or a plurality of still images showing the disassembly steps of disassembling the work vehicle 1 until the selected part appears.

[0200] This allows the maintenance personnel to quickly check the status of the portion estimated to be the cause of the failure of the work vehicle 1 .

[0201] (3) The terminal device 3 further includes a communication interface 303 (communication unit 353) for communicating with the server device 2. The processor 301 acquires a moving image or a plurality of still images showing the decomposition steps from the server device 2 via the communication interface 303 based on the selection of the part.

[0202] Thus, it is not necessary to store a moving image or a plurality of still images showing the decomposition steps in the terminal device 3 in advance.

[0203] (4) Based on the fact that a part is selected, the processor 301 causes the display 3051 to display a troubleshooting manual for the selected part, a dynamic image showing decomposition steps, or an object for displaying a plurality of still images.

[0204] Thus, after the maintenance personnel has checked the troubleshooting manual, if it is determined that the image showing the decomposition steps needs to be checked, the maintenance personnel performs an operation of selecting an object, and a dynamic image or a plurality of still images showing the decomposition steps are displayed on the terminal device 3. Therefore, compared with a configuration in which a dynamic image is automatically played after a part is selected, the terminal device 3 is more convenient for the user.

[0205] (5) The processor 301 can display a dynamic image showing the decomposition step and a plurality of still images showing the decomposition step on the display 3051. Based on the fact that the part is selected, the processor 301 causes the display 3051 to display an object 3801 for displaying a dynamic image showing the decomposition step as the above-mentioned object (see Figure 5 ) and an object 3802 for displaying a plurality of still images showing decomposition steps (see Figure 5 ).

[0206] Thus, the maintenance personnel can view a moving image showing the decomposition steps by selecting the object 3801. Also, the maintenance personnel can view a plurality of still images showing the decomposition steps by selecting the object 3802.

[0207] (6) Prioritize the multiple candidates in descending order of probability of the failure cause. When the processor 301 causes the display 3051 to display the multiple candidates, the processor 301 causes the display 3051 to further display the priority of each of the multiple candidates.

[0208] Thus, the maintenance personnel can confirm the components displayed on the diagnosis screen of the terminal device 3 in order, and can quickly identify the fault location.

[0209] (f2. Server device)

[0210] The actions in a plurality of partial screens are extracted from the actions of the terminal device 3 as described above as follows.

[0211] (1) The server device 2 includes: a processor 201 (control unit 251); a memory 202 (storage unit 252), which stores, for each part of the work vehicle 1, a dynamic image or a plurality of still images showing the decomposition steps of the work vehicle 1 until the part of the work vehicle 1 appears; and a communication interface 203 (communication unit 253), which is used to communicate with the terminal device 3.

[0212] When the work vehicle 1 fails, the processor 201 notifies the terminal device 3 of the candidate parts estimated as the cause of the failure of the work vehicle 1 from the plurality of parts mentioned above through the communication interface 203. The processor 201 reads a dynamic image or a plurality of still images showing the disassembly steps of disassembling the work vehicle 1 until the candidate parts appear from the memory 202. The processor 201 transmits the read dynamic image or a plurality of still images showing the disassembly steps to the terminal device 3 through the communication interface 203.

[0213] This allows the maintenance personnel to quickly check the status of the portion estimated to be the cause of the failure of the work vehicle 1 .

[0214] (2) When the work vehicle 1 fails, the processor 201 notifies the terminal device 3 via the communication interface 203 of a plurality of candidates (different candidates) estimated as the cause of the failure of the work vehicle 1 from among the plurality of locations. The processor 201 reads a moving image or a plurality of still images showing the disassembly steps of disassembling the work vehicle 1 until the location notified from the terminal device 3 appears from the memory 202, based on the fact that the processor 201 receives a notification of one of the plurality of candidates from the terminal device 3 via the communication interface 203. The processor 201 transmits the read moving image or a plurality of still images showing the disassembly steps to the terminal device 3 via the communication interface 203.

[0215] This allows the maintenance personnel to quickly check the status of the portion estimated to be the cause of the failure of the work vehicle 1 .

[0216] (3) Processor 201 communicates with work vehicle 1 via communication interface 203, and acquires information (fault code) transmitted from work vehicle 1. Processor 201 specifies a plurality of candidates from each of a plurality of locations based on the acquired information.

[0217] Thereby, the server device 2 can present a plurality of candidates corresponding to the fault code to the terminal device 3 .

[0218] (4) Processor 201 further acquires failure information of another work vehicle 1A from another work vehicle 1A different from work vehicle 1 via communication interface 203. Processor 201 determines the ranking based on the failure information of another work vehicle 1A in a preset period.

[0219] Thereby, the server device 2 can notify the terminal device 3 of the plurality of candidates in a state where the plurality of candidates are ranked.

[0220] (f3. Operation machinery system)

[0221] The actions in one partial screen are extracted from the actions of the working machine system 1000 as follows.

[0222] (1) The working machine system 1000 includes a working vehicle 1 , a server device 2 , and a terminal device 3 .

[0223] When a failure occurs in the work vehicle 1, the terminal device 3 displays candidates estimated as the cause of the failure of the work vehicle 1 among a plurality of parts of the work vehicle 1. The terminal device 3 notifies the server device 2 of the candidate parts.

[0224] The server device 2 transmits a moving image or a plurality of still images showing the disassembly steps for disassembling the work vehicle 1 until the part notified from the terminal device 3 appears to the terminal device 3. The terminal device 3 further displays the moving image or the plurality of still images showing the disassembly steps transmitted from the server device 2.

[0225] Accordingly, the maintenance personnel can quickly confirm the state of the part presumed to be the cause of the failure of the work vehicle 1.

[0226] (2) When a failure occurs in the work vehicle 1, the terminal device 3 displays a plurality of candidates presumed to be the cause of the failure of the work vehicle 1 among a plurality of parts of the work vehicle 1. The terminal device 3 accepts an input for selecting one part from the plurality of candidates. The terminal device 3 notifies the selected part to the server device 2.

[0227] The server device 2 transmits a moving image or a plurality of still images showing the disassembly steps for disassembling the work vehicle 1 until the part selected in the terminal device 3 appears to the terminal device 3. The terminal device 3 further displays the moving image or the plurality of still images showing the disassembly steps transmitted from the server device 2.

[0228] Accordingly, the maintenance personnel can quickly confirm the state of the part presumed to be the cause of the failure of the work vehicle 1.

[0229] <G Modification Example>

[0230] In the above-described embodiment, an example has been described in which the server device 2 stores failure diagnosis steps, disassembly steps, failure history, operation manuals, and factory manuals as shown, and the terminal device 3 acquires them as needed, but it is not limited thereto. Fig.13 The terminal device 3 may also pre-store failure diagnosis steps, disassembly steps, failure history, operation manuals, and factory manuals. In addition, when the maintenance personnel inspect the work vehicle 1, the necessary data may be read from the server device 2 in advance and stored in the terminal device 3. There is also a case where the work vehicle 1 is used in a place outside the communication range, and a situation is envisioned where the terminal device 3 cannot acquire data such as disassembly steps. In such a situation, an image showing the disassembly steps can also be displayed on the terminal device 3.

[0231] Alternatively, instead of the server device 2, the processor 301 of the terminal device 3 may determine a plurality of candidates from a plurality of parts of the work vehicle 1 based on the information (failure code) transmitted from the work vehicle 1.

[0232]

[0233] ​In addition, the processor 301 of the terminal device 3 has a priority assigning unit 2511, which can also replace the server device 2 and determine the priority (priority) based on the failure information of other work machines (for example, work vehicle 1A) different from the work vehicle 1 during a predetermined period.

[0234] The embodiments of the present specification are illustrative and are not limited to the above-described contents. The scope of the present invention is indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.
