When S31 is a negative determination, the control unit 11 repeatedly executes the determination process of S31. If S31 is affirmative, the control unit 11 executes the process of S32.

In S32, the control unit 11 highlights the selected arbitrary drawing object 43X with respect to the other drawing object 40. Similarly, the control unit 11 highlights the device object 50 (hereinafter, referred to as “device object 53X”) corresponding to the drawing object 43X to the other device objects 50. An example of highlighting in S32 is highlighting.

In S33, the control unit 11 highlights the drawing object 40 (hereinafter, referred to as “drawing object 43Y”) corresponding to the connecting component 70 to the other drawing objects 40. Similarly, the control unit 11 highlights the device object 50 (hereinafter, referred to as “device object 53Y”) corresponding to the drawing object 43Y to the other device objects 50. An example of highlighting in S33 is a broken line display. When S33 is complete, the drawing object 43X and the device object 53X are highlighted, for example, as shown in FIG. 9B. Further, the drawing object 43Y and the device object 53Y are highlighted and displayed in broken lines. FIG. 9B illustrates a case where a plurality of drawing objects 43Y and device objects 53Y exist. Further, in S33, a line segment indicating the connection relationship between the drawing object 43X and the drawing object 43Y may be highlighted with a broken line or the like.

In S41, the control unit 11 determines whether or not the correction instruction of the display position of any of the device objects 50 displayed on the unit display unit 13B is performed, for example, via a gesture. For example, the maintenance worker 90 gives a correction instruction when the position of the parts A1 to A16 of the equipment unit 82 in the real space and the display position of the equipment object 50 corresponding to the parts A1 to A16 are large.

When S41 is a negative determination, in other words, when there is no correction instruction, the control unit 11 repeatedly executes the determination process of S41. When S41 is an affirmative determination, in S42, the control unit 11 corrects the display position of the device object 50, which is the target of the correction instruction, according to the instruction of the maintenance worker 90. According to the display device 10, for example, even when the device object 50 is not correctly displayed on the parts A1 to A16, the display position of the device object 50 can be corrected according to the instruction of the maintenance worker 90.

<4. Modification example>
The above-described embodiment is an example of possible forms of the maintenance work support system, the maintenance work support method, and the maintenance work support program according to the present invention, and is not intended to limit the forms. The maintenance work support system, the maintenance work support method, and the maintenance work support program according to the present invention may take a form different from the form exemplified in the embodiment. One example thereof is a form in which a part of the configuration of the embodiment is replaced, changed, or omitted, or a new configuration is added to the embodiment. An example of a modification of the embodiment is shown below.

<4-1>
In the above embodiment, the relationship between the arrangement of the plurality of parts A1 to A16 in the actual machine image information and the arrangement of the plurality of parts A1 to A16 in the drawing information has been mainly described when the correspondence between the arrangements is different. However, the maintenance work support system 20 can be applied even when the correspondence of each arrangement is the same. For example, when it is desired to refer to the mechanical drawing of the equipment unit 82 of the industrial equipment, the correspondence between the arrangement of the plurality of parts in the actual machine and the arrangement of the plurality of parts in the drawing is almost the same. However, depending on the type of the equipment unit 82, the number of parts is very large, and it is difficult to easily grasp the correspondence between the arrangement of the plurality of parts in the actual machine and the arrangement of the plurality of parts in the drawing. Even in this modification, at first, the correspondence between an arbitrary part in the image information of the actual machine and the part in the drawing information corresponding to the arbitrary part cannot be grasped, but the control unit 11 controls the display state. As a result, the correspondence between the two can be easily grasped. Specifically, as in the above embodiment, it can be realized by the control unit 11 executing at least one of the first display control and the second display control. As a result, the maintenance work of the equipment unit 82 can be efficiently performed.

<4-2>
In the above embodiment, the size of the device object 50 is substantially the same as that of the corresponding parts A1 to A16, but the size of the device object 50 can be expanded based on the contour information of the device object 50. You may. The contour information of the device object 50 is information including size information of the device object 50 and arrangement information with respect to coordinates. The contour information of the device object 50 may be stored in the database D2 or may be stored in another database. In this modification, even when the sizes of the parts A1 to A16 included in the device unit 82 are relatively small, the device object 50 can be enlarged, so that the device object 50 can be easily selected.

<4-3>
In the above embodiment, the device object 50 is used as the actual machine image information, but the actual machine image information can be arbitrarily changed. The display device 10 of the modified example uses the actual machine image information defined based on the contour information and the position information of the parts A1 to A16 as the actual machine image information. The contour information of the parts A1 to A16 is information including size information of each part A1 to A16 and arrangement information with respect to coordinates. The contour information may be stored in, for example, the database D2, may be stored in another database, or may be generated through analysis of the captured image by the camera 12. The position information of the parts A1 to A16 is generated based on the database D2.

<4-4>
In the above embodiment, the device object 50 is selected by hand tracking or eye tracking in the corresponding component confirmation mode, but the selection method of the device object 50 can be arbitrarily changed. In the display device 10 of the modified example, for example, the device object 50 is selected based on the voice information read out by the maintenance worker 90 with the names of the parts corresponding to the device object 50. In another modification, for example, the equipment object 50 is selected based on the maintenance worker 90 visually recognizing the character information of the parts described in the equipment object 50. In this modification, for example, when it is detected that the character information of a specific device object is visually recognized for a certain period of time, the device object 50 is selected. In yet another modification, the device object 50 is selected by enclosing an arbitrary device object 50 using an AR cursor.

<4-5>
In the above embodiment, the drawing object 40 is selected by hand tracking or eye tracking in the corresponding component confirmation mode, but the selection method of the drawing object 40 can be arbitrarily changed. In the display device 10 of the modification, the drawing information includes a plurality of component-specific information including the component names of the plurality of components and at least one of the symbols set for each of the plurality of components. When any component-specific information among the plurality of component-specific information is selected, the control unit 11 controls the arbitrary component-specific information among the actual machine image information displayed on the unit display unit 13B in the first display control. The display state of the unit display unit 13B is controlled so that the component corresponding to the above can be specified. Recognition of component-specific information is performed based on at least one of voice information and text information. In yet another modification, the drawing object 40 is selected by enclosing an arbitrary drawing object 40 using an AR cursor.

<4-6>
In the above embodiment, the drawing display unit 13A displays the drawing information in the display screen fixed mode, but the drawing display unit 13A is configured to be able to select whether to display the drawing display unit 13A in the display screen fixed mode or the world coordinate system fixed mode. You may. As described in the above embodiment, the unit display unit 13B displays the AR image which is the actual machine image information so as to be superimposed on the equipment unit 82. When the line of sight of the maintenance worker 90 is changed, in other words, when the position of the display device 10 is changed, the control unit 11 maintains the state in which the actual machine image information is superimposed on the device unit 82. Since the unit display unit 13B is moved, the moved unit display unit 13B and the drawing display unit 13A may overlap with each other. In such a case, in this modification, the drawing display unit 13A can be moved to the outside of the display unit 13 by changing the display mode of the drawing display unit 13A to the world coordinate system fixed mode. The outside of the display unit 13 is, for example, a three-dimensional space located in the line-of-sight direction in which the device unit 82 does not exist. In this modification, when the drawing display unit 13A is being confirmed while the unit display unit 13B is being confirmed, the drawing display unit 13A can be easily confirmed by facing the line-of-sight direction in which the device unit 82 does not exist. The work efficiency of maintenance work is improved.

<4-7>
The control unit 11 of the display device 10 identified the photographed device unit 82 from among the plurality of device units 82 based on the AR marker photographed by the camera 12. However, the method of specifying the equipment unit 82 can be arbitrarily changed. The display device 10 of the modified example is, for example, when an AR marker is provided for each industrial device 80, a device unit that performs maintenance work from a plurality of device units 82 included in the industrial device 80 specified based on the AR marker. A menu screen for selecting 82 is displayed on the display unit 13. The maintenance worker 90 selects the equipment unit 82 to perform the maintenance work from the menu screen. When there is only one device unit 82 included in the industrial device 80, the display of the menu screen is omitted.

<4-8>
In the above embodiment, the control unit 11 calculates the position of the display device 10 with respect to the device unit 82 based on the detection results of the various sensors 14, but the configuration for calculating the position of the display device 10 with respect to the device unit 82. Can be changed arbitrarily. In one example, when a stereo camera is adopted as the camera 12, the control unit 11 can calculate the position of the display device 10 with respect to the device unit 82 based on the image information captured by the stereo camera.

<4-9>
In S22 of the second display control, the control unit 11 extracts the drawing object 42X from the drawing including the parts corresponding to the device object 52X, but the maintenance worker 90 may extract the drawing object 42X. .. In this modification, when there are a plurality of drawings including parts corresponding to the device object 52X, it is preferable to provide a page feed function. Even in the first display control, when there are a plurality of drawings relating to the specified device unit 82, it is preferable to provide a page feed function. The drawings are preset to be displayed in a fixed page order, and when a plurality of drawings are extracted, it is preferable that the drawings are displayed in order from the youngest page. Further, the type of drawing can be selected in advance by the maintenance worker 90.

<4-10>
In the above embodiment, the databases D1, D2, D3, the drawing information, and the actual machine image information are managed by the server 30, but the databases D1, D2, and D3 do not necessarily have to be managed by the server 30. No. The databases D1, D2, D3, the drawing information, and the actual machine image information may be stored in, for example, the storage unit 16.

<4-11>
In the above embodiment, the image displayed on the display unit 13 of the display device 10 may be shared with, for example, a supporter who is away from the maintenance worker 90. That is, the display device 10 may be used for so-called remote maintenance support. In this case, the image shared with the supporter may not include an area that should not be shared with the supporter. In this modification, when the equipment unit 82 for performing maintenance work is specified, it is preferable that the supporter specifies the drawing information to be displayed on the drawing display unit 13A in the first display control. For example, when there are a plurality of drawings corresponding to the specified equipment unit 82, a supporter who is an expert specifies the necessary drawings rather than the case where the maintenance worker 90 selects the necessary drawings from these drawings. As a result, the time required for maintenance work can be shortened.
