Description

Technical Field

[0001] The present invention relates to a work support device and a work support program.

Background Art

[0002] In maintenance facilities such as automobile repair factories and automobile dealerships, inspection work is carried out for various inspection items according to, for example, vehicle models and inspection times (Patent Document 1).

[0003] In such maintenance facilities, a mechanic opens the page of the inspection location from a thick manual and proceeds with the inspection work while checking various work procedures described on that page, such as the order of tightening bolts and the specified tightening torque of those bolts.

[0004] However, the more inspection locations there are for the maintenance target, the more times it is necessary to repeatedly check the work procedures, resulting in poor work efficiency.

Summary of the Invention

Problems to be Solved by the Invention

[0006] Therefore, the present invention has been made to solve the above-described problems, and its main object is to improve work efficiency in maintenance facilities.

Means for Solving the Problems

[0007] In other words, the work support device according to the present invention is a work support device that supports work in a maintenance area, and includes a display control unit that displays a maintenance target symbol that mimics the maintenance target on a display, and selectably displays a plurality of inspection points included in the maintenance target on the display, and when one of the plurality of inspection points is selected, the display control unit switches all or part of the display content on the display to a work screen corresponding to the selected inspection point.

[0008] With this type of work support equipment, the worker can select an inspection point, and the display content will switch to a work screen corresponding to the selected inspection point. This eliminates the need to search for and open the page for the inspection point in the instruction manual, thereby improving work efficiency.

[0009] Incidentally, recently there has been a request to change the method of managing inspection results at the aforementioned maintenance facility from manually entering inspection results on paper to, for example, digital management on a server. Therefore, it is preferable to further include a measurement value receiving unit that receives measurement values ​​measured by a tool during the inspection work of the inspection point, and for the display control unit to display the maintenance target symbol or a part symbol that mimics the inspection point along with the measurement value received by the measurement value receiving unit on the work screen. With this configuration, not only can measured values ​​be digitally managed, but these values ​​are also displayed along with the maintenance target symbol or part symbol, allowing for an intuitive understanding of the measured values ​​and inspection locations, thereby further improving work efficiency.

[0010] It is preferable that the display control unit overlays the measured value onto the maintenance target symbol or the part symbol. With this configuration, the symbols to be serviced or the symbols to be parts are displayed prominently on the work screen, improving visibility and design, while also ensuring ease of use by displaying measured values.

[0011] For example, if the inspection point is brake pads and the remaining thickness is to be measured, the number of brake pads installed will differ depending on whether it is a so-called double disc brake (where disc rotors are located on both the left and right sides of the wheel) or a single disc brake, and therefore the number of points to measure will change. Even when there are several types of inspection points, in order to flexibly accommodate the display mode of the work screen, it is preferable that the display control unit displays the type of inspection point in a selectable manner, and switches the arrangement or number of measurement value display areas, which are the display areas for the measured values, according to the selection of that type.

[0012] Incidentally, while the maintenance targets may include not only four-wheeled vehicles and two-wheeled vehicles but also large vehicles, it is preferable that the display control unit displays a symbol of a large vehicle on the display as the maintenance target symbol, and also displays part symbols that resemble wheels as inspection points on the display, with the number and arrangement of these symbols selectable. This makes it possible to use the work support device according to the present invention for inspection work on various large vehicles.

[0013] In the maintenance of large vehicles with many wheels, or vehicles with more fasteners such as nuts on each wheel than typical vehicles (for example, buses), the total number of fasteners to be inspected increases, and so does the amount of data obtained from measurements such as fastening operations on these fasteners. Therefore, even if we were to display each measurement value in a smaller size, or display the measurement values ​​on a separate screen that does not show the maintenance target symbol, it would still be difficult to display all the measurement values ​​at once. As a result, problems arise such as the need to scroll the screen when, for example, you want to check the measurement values ​​of an inspection point that has already been inspected, which impairs work efficiency.

[0014] Therefore, it is preferable that the display control unit displays the measured values ​​of the selected inspection location on the display and hides the measured values ​​of the other inspection locations from the display. With this setup, the display control unit displays the measurement value for only one selected inspection point, hiding the values ​​for the other inspection points. Compared to displaying the measurement values ​​for multiple inspection points simultaneously, the measurement value for the selected inspection point can be displayed larger, improving visibility. Furthermore, the desired measurement value can be checked with a single touch without scrolling the screen, improving work efficiency.

[0015] Preferably, the work support device is configured to automatically select the next inspection location according to a predetermined inspection sequence when the inspection work at one of the inspection locations is completed. This allows inspection work to proceed smoothly, and if it is necessary to adhere to a specific inspection sequence for each inspection point, the work can be carried out without making any mistakes in that sequence.

[0016] It is preferable that the display control unit displays the selected inspection location in a manner that allows it to be distinguished from other inspection locations. This allows workers to be aware of the inspection points while they are working, preventing human errors caused by misidentification of inspection points.

[0017] In order to accommodate various large vehicles, it is preferable that the display control unit displays on the display at least one of the number of fasteners used on the wheel, the wheel specifications, or the target torque for tightening the fasteners.

[0018] The work support program according to the present invention is a work support program for supporting work at a maintenance yard, which causes a computer to function as a display control unit that displays a symbol imitating a maintenance target on a display and also displays a plurality of inspection points included in the maintenance target on the display so that they can be selected. When one of the plurality of inspection points is selected, the display control unit switches the entire or part of the display content on the display to a work screen corresponding to the selected inspection point. Such a work support program can achieve the same operational effects as the above-described work support device.

Effects of the Invention

[0019] According to the present invention configured as described above, it is possible to improve the work efficiency at the maintenance yard, and furthermore, it contributes to the digital management of inspection results.

[0021] [First Embodiment] A first embodiment of the work support device according to the present invention will be described below with reference to the drawings.

[0022] The work support device 20 according to this embodiment is used, for example, in a maintenance facility such as an automobile repair shop or automobile dealership, and constructs a work support system 100 that assists workers such as mechanics in their work. In this embodiment, the vehicle to be serviced Z is a vehicle such as a motorcycle, a four-wheeled vehicle, or a large vehicle with six or more wheels.

[0023] As shown in Figure 1, this work support system 100 includes a support information storage unit 10 that stores support information containing various data related to the maintenance target Z, and a work support device 20 that is operated by a worker to acquire support information from the support information storage unit 10.

[0024] <Support Information Storage Unit 10> First, let's explain the support information storage unit 10. The support information storage unit 10 is set in a predetermined area of ​​memory located outside the work support device 20.

[0025] This support information storage unit 10 stores various data related to the vehicle being serviced Z. Specifically, it stores data such as past inspection results and data showing the warranty details at the time of vehicle purchase.

[0026] Therefore, the support information storage unit 10 stores support information received by the work support equipment 20 during inspection work, and the worker can proceed with the inspection work based on this support information.

[0027] As shown in Figure 2, the support information is a combination of identification information that identifies the maintenance target Z and inspection location information that indicates the inspection points of the maintenance target Z.

[0028] In addition, depending on the work performed at the inspection site, target values ​​may be predetermined, such as the specified torque for fastening bolts. In such cases, as shown in Figure 2, the aforementioned identification information and inspection site information may be further linked to the target values ​​predetermined according to the work performed at the inspection site.

[0029] The identification information is unique and distinct information pre-assigned to each maintenance target Z. In this embodiment, the maintenance target Z is a vehicle such as a motorcycle or a four-wheeled vehicle, and the identification information is a string of characters indicating the individual vehicle identification number assigned to each vehicle. The vehicle identification number may be, for example, the vehicle registration number or vehicle number written on the license plate, or the chassis number, but is not limited to these.

[0030] The inspection point information indicates the points that are inspected during various inspection procedures for the maintenance target Z. For example, it may indicate the points inspected during periodic inspections, oil changes, filter changes, or specific maintenance.

[0031] An example of inspection point information is the names of the components of the vehicle Z being serviced. More specifically, as shown in Figure 3, it indicates fastening points such as the front axle nut, front axle clamp bolt, torque rod, and rear caliper pad pin.

[0032] Another example of inspection point information is the location of components on the vehicle being serviced, Z. More specifically, as shown in Figure 4, this indicates the locations of the brake pads on a motorcycle, such as the Front Right, Front Left, and Rear.

[0033] <Work support equipment 20> Next, we will explain the work support equipment 20. The work support device 20 is a portable or stationary terminal device such as a tablet, smartphone, or laptop computer, equipped with a display D, CPU, and memory, and performs at least the functions of an identification information receiving unit 21, a display control unit 22, and an inspection location receiving unit 23, as shown in Figure 5, based on a program stored in the memory.

[0034] The identification information receiving unit 21 receives the input identification information. Embodiments for inputting identification information include the work support device 20 being equipped with input means such as a touch panel or keyboard, or being equipped with an identification code for reading the identification information and an imaging means such as a camera for capturing this identification code.

[0035] In this embodiment, for example, the identification code printed on the vehicle inspection certificate of the vehicle to be serviced Z, or the license plate of the vehicle to be serviced Z, is captured by a camera, and the vehicle identification number of that vehicle is output as identification information to the identification information receiving unit 21 and received.

[0036] Based on the identification information received by the identification information receiving unit 21, the display control unit 22 displays the maintenance target symbol S1, which is a symbol that mimics the maintenance target Z, on the display D, as shown in Figures 3 and 4.

[0037] The image data of the maintenance target symbol S1 is linked to the identification information described above and may be stored in the memory of the work support device 20 or in the support information storage unit 10.

[0038] For example, if the vehicle to be serviced Z is a motorcycle, the display control unit 22 displays a symbol resembling a motorcycle as the vehicle to be serviced symbol S1 on the display D, as shown in Figure 3.

[0039] Furthermore, based on the identification information described above, the display control unit 22 displays multiple inspection points included in the maintenance target Z on the display D in a selectable format.

[0040] Specifically, the display control unit 22 obtains inspection location information linked to identification information from the support information storage unit 10 and displays the inspection location indicated by this inspection location information on the display D. In other words, the display control unit 22 simultaneously displays the maintenance target symbol S1 and the inspection location on the same screen.

[0041] Examples of how inspection points can be displayed include a method that allows users to select the name of the component being inspected, as shown in Figure 3, and a method that allows users to select the location of the component being inspected, as shown in Figure 4.

[0042] The inspection location reception unit 23 receives inspection location information indicating the inspection location selected by the user from among the inspection locations displayed by the display control unit 22.

[0043] As an embodiment for selecting inspection points, as shown in Figures 3 and 4, the work support device 20 may be equipped with input means such as a touch panel or mouse for selecting one of several inspection points. Voice input using a microphone or the like may also be used for selecting inspection points.

[0044] In this embodiment, multiple names of fastening points and multiple locations of components are displayed on the display D as inspection points. When an operator selects one of these points, for example via a touch panel, the location of that fastening point or component is output to the inspection point reception unit 23 as inspection point information and accepted.

[0045] Furthermore, in this embodiment, when one of the multiple inspection points is selected, the display control unit 22 switches all or part of the display content of the display D to a work screen corresponding to the selected inspection point.

[0046] To explain the switching of this work screen in more detail, we will discuss the fastening process using bolts and other fasteners.

[0047] First, before starting this tightening operation, the display control unit 22 displays multiple fastening points as selectable inspection points on the display D, as shown in Figure 3.

[0048] Then, when one fastening point is selected from among these fastening points, the display control unit 22 switches the display content of the display D to the work screen corresponding to the selected fastening point, i.e., the tightening torque measurement screen, as shown in Figure 6. In this embodiment, the display control unit 22 switches the entire display content of the display D.

[0049] This work screen displays, for example, the number of fasteners used for fastening the selected fastening point. Specifically, it shows the numbered individual fasteners. In this case, the numbers for the fasteners on the left and right sides of the fastening point are displayed in two columns.

[0050] Then, a predetermined area corresponding to each of these numbers is set as the measurement value display area V1, which displays the tightening torque during the tightening operation.

[0051] Furthermore, as shown in Figure 6, the display control unit 22 may obtain a target value associated with the inspection location information indicating the selected fastening location (inspection location) from the support information storage unit 10 and display this target value in the target value display area V2 of the measurement screen. The display control unit 22 may also be configured to accept a target value entered by the user and display that target value in the target value display area V2.

[0052] Then, during the tightening work of this fastening part, when the worker tightens the fastener using, for example, a torque wrench, the actual tightening torque during the fastening work is transmitted from the torque wrench or a torque measuring device attached to the wrench to the work support device 20.

[0053] As shown in Figure 5, the work support device 20 of this embodiment includes a measurement value receiving unit 24 that receives measurement values ​​measured using the tool X during each inspection operation, and the display control unit 22 displays the measurement values ​​received by the measurement value receiving unit 24 in the measurement value display area V1 described above, for example, in real time.

[0054] Next, as another embodiment of switching between work screens, we will consider the brake pad inspection procedure.

[0055] First, before starting this tightening operation, the display control unit 22 displays multiple positions of the brake pad as selectable inspection points on the display D, as shown in Figure 4.

[0056] Then, when one of these positions is selected, the display control unit 22 switches the display content of the display D to a work screen corresponding to the selected position, namely the screen for measuring the remaining amount of the brake pad at the selected position, as shown in Figure 7.

[0057] On this work screen, the selected brake pad is displayed in a way that allows it to be distinguished from other brake pads. In this embodiment, the display control unit 22 switches a portion of the display content on the display D.

[0058] More specifically, this work screen is divided into multiple corresponding areas V3, each corresponding to a different brake pad position. The display control unit 22 makes the display characteristics of the corresponding area V3 corresponding to the selected brake pad, such as color, brightness, and pattern, different from the display characteristics of the corresponding areas V3 corresponding to the other brake pads.

[0059] In the configuration described above, the display control unit 22 displays a measurement value display area V1 that displays a measurement value related to the remaining brake pad length in each of the corresponding areas V3 that are separated according to the position of the brake pad.

[0060] This measurement value display area V1 is displayed so as to overlap with a part of the motorcycle symbol, which is the maintenance target symbol S1. The measurement values ​​displayed in this measurement value display area V1 will also overlap with the maintenance target symbol.

[0061] Incidentally, as shown in Figure 7, the display control unit 22 displays the same number of measurement value display areas V1 as the number of measurement points in the inspection area. In the brake pad remaining thickness inspection work, for example, the number of brake pads installed differs depending on whether it is a so-called double disc brake where disc rotors are arranged on both the left and right sides of the wheel, or a single disc brake, and the number of measurement points changes accordingly.

[0062] Therefore, the display control unit 22 of this embodiment displays the type of brake pad, which is the inspection point, in a selectable manner, and switches the measured value display area V1 according to the selected type. Here, "type" refers to the specifications or type of the inspection point.

[0063] More specifically, as shown in Figure 7, the display control unit 22 displays the type of inspection location in a selectable type selection area V4 set in a predetermined area of ​​the measurement screen.

[0064] In this embodiment, the type of brake pad to be inspected, either single-disc or dual-disc, can be selected using an input means such as a touch panel or mouse. Voice input using a microphone or the like may also be used to select the brake pad type.

[0065] Furthermore, as shown in Figure 5, the work support device 20 of this embodiment includes a type reception unit 25 that receives type information indicating the selected type. Based on the type information received by the type reception unit 25, the display control unit 22 changes the way the corresponding area V3 is divided as described above, and switches the arrangement and number of measurement value display areas V1. Depending on the selected type, it is also possible to switch only the arrangement without changing the number of measurement value display areas V1.

[0066] In addition, during the inspection work described above, the work screen may switch when the worker selects the next inspection location after completing the measurement of one inspection location, or the display control unit 22 may automatically switch the work screen to the screen corresponding to the next inspection location as soon as the measurement of one inspection location is completed.

[0067] With the work support device 20 configured in this way, when the worker selects an inspection point, the display content on display D switches to a work screen corresponding to the selected inspection point. This eliminates the need to search for and open the page for the inspection point in the instruction manual, thereby improving work efficiency.

[0068] Furthermore, since the measurement value receiving unit 24 receives the measurement values ​​measured by the tool X during the inspection work of the inspection points, digital management of the measurement values ​​becomes possible. Furthermore, since these measured values ​​are displayed along with the maintenance target symbols, the measured values ​​and inspection points can be intuitively grasped, leading to further improvements in work efficiency.

[0069] In addition, since the display control unit 22 overlays the measured value onto the maintenance target symbol, by displaying the maintenance target symbol or part target symbol larger on the work screen, visibility and design can be improved, while also ensuring good workability by displaying the measured value.

[0070] Furthermore, the display control unit 22 displays the type of inspection location in a selectable format, and switches the arrangement and number of measurement value display areas V1 according to the selected type, so that the arrangement of measurement value display areas V1 can be flexibly switched according to the type of inspection location. Furthermore, by switching the arrangement and number of measurement value display areas V1 in this way, it is possible to quickly grasp, for example, the locations and number of locations where brake pad remaining length is measured.

[0071] [Modified version of the first embodiment] Furthermore, the present invention is not limited to the above first embodiment.

[0072] For example, in the above embodiment, the work support system 100 was described as being used for tightening work using a torque wrench or measuring the remaining amount of brake pads using measuring tools such as calipers, but it may also be used for other purposes, such as measuring the groove depth of tires using a depth gauge.

[0073] In the above embodiment, the display control unit 22 displayed the measured value together with the maintenance target symbol S1. However, as shown in Figure 8, it may also display the measured value together with a component symbol S2 that mimics the components of the maintenance target Z. The work screen shown in Figure 8 is a screen for measuring the tightening torque during the tightening of the oil drain bolt. The display control unit 22 displays a part symbol S2 that simulates the oil drain, which is the inspection point, and displays a measurement value display area V1 that overlaps with at least a part of this part symbol S2.

[0074] Furthermore, in the above embodiment, the display control unit 22 switches the display content of the display D to a tightening torque measurement screen or a brake pad remaining length measurement screen when one of the multiple inspection points is selected. However, it is not always necessary to switch to a measurement screen; it may also switch to a work screen that corresponds to the procedure for the selected inspection point. Examples of such work screens include a confirmation screen that displays the inspection items for each inspection point and allows the user to check whether or not the inspection of those items has been completed.

[0075] In the above embodiment, identification information was input using input means such as a touch panel or keyboard, or an imaging means, but voice input using a microphone or the like may also be used.

[0076] Maintenance target Z is not limited to vehicles; it may also include mobile objects such as bicycles, trains, aircraft, ships, agricultural machinery, and various industrial machines.

[0077] [Second Embodiment] Next, a second embodiment of the work support device 20 according to the present invention will be described with reference to the drawings.

[0078] The work support device 20 of this second embodiment is particularly useful for inspection work on large vehicles, and, like the first embodiment, is equipped with functions such as a display control unit 22 that controls the display content of the display D. Here, "large vehicle" refers to a vehicle with at least six or more wheels, such as a large automobile or a trailer (towed vehicle).

[0079] Furthermore, the switching of display content by this display control unit 22 is a distinctive feature that differs from the above embodiment, and will be described in detail below.

[0080] First, referring to Figure 9, we will explain the contents of the settings screen used before the inspection work.

[0081] As shown in Figure 9, the display control unit 22 displays the contents of various setting items on the settings screen in a selectable format. The specific method of selection may include using input means such as a touch panel or mouse, or using voice input via a microphone.

[0082] Specifically, the display control unit 22 displays at least the number and arrangement of wheels of a large vehicle, as a maintenance target symbol S1 that mimics the large vehicle to be maintained.

[0083] In this case, since the wheels are an inspection point for the large vehicle being serviced, the display control unit 22 displays multiple inspection points included in the service target along with the service target symbol S1.

[0084] More specifically, the display control unit 22 in this embodiment displays a part symbol S2 that mimics a wheel, which is the inspection point, and allows the user to select whether to display or hide this part symbol S2. In this example, a part symbol S2 is a representation of the tire that makes up the wheel, but it may also be a representation of the wheel that makes up the wheel.

[0085] Through this part symbol S2, the number and arrangement of wheels are displayed as selectable options as described above, and by displaying at least six or more selectable options, it is possible to display maintenance target symbols S1 that simulate various large vehicles. Here, in order to display double tires as well, six or more pairs of wheels are displayed as selectable options.

[0086] In this settings screen, the display control unit 22 displays on the display D, allowing users to select multiple work-related information items related to wheel inspection work, in addition to the number and arrangement of wheels. Specifically, as shown in Figure 9, the number of fasteners such as nuts or bolts used on one wheel, the standards that define the shape of the wheel, and the target torque for tightening fasteners such as nuts or bolts are displayed as work-related information. In the following explanation, nuts will be used as an example of fasteners.

[0087] However, some or all of the above-mentioned settings do not necessarily need to be set by the operator. For example, by taking a photograph of the license plate of the item to be serviced, the contents of the settings stored in relation to that license plate may be automatically set and displayed by the display control unit 22. In this configuration, errors due to manual input can be reduced.

[0088] Furthermore, since the value set as the number of nuts is limited to a few options depending on the wheel specifications, the display control unit 22 may display an inappropriate combination of the number of nuts and the wheel specifications as unselectable.

[0089] Once the setting process is completed by operating the settings screen described above, and this is confirmed, for example, by pressing the OK button, the display control unit 22 switches the display content of display D from the settings screen to the work screen shown in Figure 10.

[0090] In this work screen as well, the display control unit 22 displays a maintenance target symbol S1 that mimics the maintenance target. This maintenance target symbol S1 mimics a large vehicle, and specifically reflects the number and arrangement of wheels selected in the settings screen described above. In this embodiment, in addition to the number and arrangement of wheels, the contents of the setting items selected in the settings screen described above are also displayed on the work screen by the display control unit 22.

[0091] More specifically, the display control unit 22 of this embodiment displays a part symbol S2 that resembles a wheel, which is an inspection point, on the work screen, and displays a selectable part symbol S2 that resembles a wheel for each of the multiple inspection points.

[0092] Then, for example, when an operator selects one inspection point from several at the start of an inspection, the display control unit 22 displays the selected part symbol S2 in a way that makes it distinguishable from the other part symbols S2.

[0093] Examples of methods to make the selected inspection area identifiable include adding a mark M such as a border around the selected inspection area, or changing the display method such as the color or brightness of the selected inspection area from that of other inspection areas. This allows the worker performing the inspection to recognize the selected inspection area.

[0094] Furthermore, when one inspection point is selected, the display control unit 22 displays the measurement result field A for the selected inspection point on the same screen as the maintenance target symbol S1. At this time, the measurement result field A displayed by the display control unit 22 is only that which corresponds to the selected inspection point, and the measurement result field A corresponding to the other inspection points is not displayed.

[0095] The measurement result field A is provided with the same number of measurement value display areas V1 as the number of nuts selected in the settings screen described above. In this embodiment as well, as in the first embodiment, when an operator fastens a nut using, for example, a torque wrench, the actual tightening torque during the fastening operation is transmitted from the torque wrench or a torque measuring instrument attached to the wrench to the work support device 20, and the tightening torque is displayed as a measurement value by the display control unit 22, for example, sequentially in the measurement value display area V1 described above.

[0096] With this configuration, the display control unit 22 of this embodiment displays the measurement value of only one selected inspection point on the display D, and hides the measurement values ​​of other inspection points from the display D, even if they have been obtained.

[0097] Then, once the tightening of all nuts included in one inspection point is completed and the tightening torque of each nut is displayed in the measurement value display area V1, in this embodiment, the work support device 20 automatically selects the next inspection point.

[0098] More specifically, the work support device 20 of this embodiment is equipped with a function (hereinafter also referred to as the automatic feed function) that automatically selects each inspection point sequentially according to a predetermined inspection order. When the inspection work at one inspection point is completed, this function selects the next inspection point according to the predetermined inspection order.

[0099] The work support device 20 here is configured to allow the user to select from multiple inspection sequences for the automatic feeding function. As shown in Figure 10, the inspection sequence patterns are displayed by the display control unit 22 in a switchable format, for example, in the sequence display field V5 on the work screen.

[0100] Specific examples of inspection sequences include selecting inspection points in a clockwise direction starting from the first selected point, or selecting them in a counter-clockwise direction. Alternatively, the inspection order may be determined according to each standard selected on the settings screen mentioned above. Specifically, this could involve inspecting the inspection points located on the inside first, followed by the inspection points located on the outside.

[0101] In this configuration, the display control unit 22 switches the display content of the display D to a work screen corresponding to the selected inspection location each time one of the multiple inspection locations is selected.

[0102] As shown in Figure 11, the display control unit 22 of this embodiment is configured to switch a portion of the display content of the display D according to the selected inspection location. Specifically, it automatically advances the marks M, such as borders, that indicate the selected inspection location according to the inspection sequence described above, and switches the measurement result field A from that of the previously selected inspection location to that of the newly selected inspection location.

[0103] The above steps are repeated until all inspection points are completed. In this case, the measurement results may be compiled and printed out on a single inspection sheet.

[0104] With the work support device 20 configured in this way, the display control unit 22 displays the measurement value of only one selected inspection point and hides the measurement values ​​of the other inspection points. Compared to displaying the measurement values ​​of multiple inspection points at once, the measurement value of the selected inspection point can be displayed larger, resulting in better visibility, and the desired measurement value can be checked with a single touch, improving work efficiency.

[0105] On the other hand, when displaying the measured values ​​of multiple inspection points at once, not only in large vehicles with many wheels like in this embodiment, but also in vehicles with more fasteners such as nuts used on each wheel than typical vehicles (for example, buses), the total number of nuts, and therefore the number of measured values ​​obtained, increases. Even if each measured value is displayed in a smaller size, or the measured values ​​are displayed on a separate screen that does not show the maintenance target symbol S1, it is difficult to display all the measured values ​​at once. As a result, for example, when you want to check the measured values ​​of an inspection point that has already been inspected, you will need to scroll the screen, which impairs work efficiency.

[0106] Furthermore, the display control unit 22 displays a maintenance target symbol S1 that mimics the large vehicle to be maintained, allowing the user to select at least the number and arrangement of wheels of that large vehicle. Therefore, the work support device 20 according to the present invention will be useful for inspection work on various large vehicles.

[0107] Furthermore, the selected inspection points are displayed in a way that makes them distinguishable from other inspection points, allowing workers to recognize the inspection points during their work and preventing human errors caused by misidentification of inspection points.

[0108] Furthermore, once the inspection of one inspection point is completed, the next inspection point is automatically selected, allowing the inspection process to proceed smoothly. Additionally, if a specific inspection order is required, the system ensures that the inspection is carried out correctly.

[0109] In addition, the display control unit 22 displays an inappropriate combination of the number of nuts and the wheel specifications, making it impossible to select, thereby preventing input errors when making these selections.

[0110] [Modified version of the second embodiment] Furthermore, the present invention is not limited to the described second embodiment.

[0111] In the second embodiment described above, the inspection work involved tightening nuts, but other inspection work could include measuring tire tread depth, air pressure, or hardness. For example, in the process of measuring the groove depth of a tire, the display control unit 22 may display the number of measurement points for a single tire as a selectable setting item on the settings screen.

[0112] By the way, if a single wheel uses eight nuts, and one of them is accidentally tightened twice, then nine measurements will be obtained for that single wheel. In this case, in the embodiment described above, once the inspection of one inspection point is completed, the next inspection point is automatically selected. Therefore, after eight measurement values ​​have been obtained, the next inspection point is automatically selected, and the ninth measurement value is unknowingly entered as the measurement value for the next inspection point. Therefore, in order to prevent such input errors, the system may be configured so that the worker can select the next inspection point after the inspection work on one inspection point is completed, and specifically, the work support device 20 may be configured to allow the automatic feeding function to be switched ON or OFF.

[0113] [Other embodiments] However, the present invention is not limited to the first and second embodiments described above.

[0114] For example, one method of selecting an inspection point may involve acquiring the worker's location information and automatically selecting an inspection point close to the worker based on that location information.

[0115] Furthermore, it goes without saying that the present invention is not limited to the embodiments described above, and various modifications are possible without departing from its spirit. [Explanation of symbols]
