When a virtual tour of a tour is performed under the initiative of a worker using a certain patrol scenario, the worker uses the input device 7 to arbitrarily move the position of the viewpoint in the virtual world. At this time, the viewpoint data control unit 8 checks the interference between the 3D data in the virtual world and the viewpoint position, and restricts the movement of the viewpoint to a place where the worker cannot enter. The central control unit 5 displays the state of the plant at the viewpoint on the display device 6 as the viewpoint moves. Further, the central control unit 5 monitors the movement of the viewpoint moved by the worker, and when the position of the viewpoint reaches the viewpoint position at the time of execution of each work content described in the patrol scenario, the extracted motion / related information is obtained. Among the operations, the operation / related operation relating to the work content is extracted, the operation / related operation is reproduced in a virtual world, and the pattern is displayed on the display device 6. As described above, when the workers virtually experience the patrol work,
An arbitrary route can be selected, and a more realistic virtual experience can be provided.

Embodiment 3 In the first embodiment, when a device in a plant is expressed as a 3D model, it is expressed as an aggregate of a plurality of 3D models. Therefore, in the third embodiment, the 3D data of each device stored in the 3D data management unit 1 is hierarchically managed according to the level of detail. For example, taking a certain control panel as an example, there is a single 3D model called a control panel body as shown in FIG. When the level of detail is increased by one step, in addition to that, Fig. 3- (2)
There are left and right doors, as shown in FIG. 3, and when the level of detail is further increased, there are a plurality of switches and meters as shown in FIG. When displaying the state of the plant on the display device 6 according to the viewpoints of the virtual world, the central control unit 5 determines the viewpoint position and the 3D of each device.
The distance to the model is calculated, and according to the distance, if the distance is far, only the upper 3D model of the hierarchical structure is displayed. If the distance is closer, even the more detailed 3D model at the lower part of the hierarchical structure is displayed.

As described above, when the worker virtually experiences the inspection work, detailed information can be obtained for the operation target device at hand. In addition, since the remote devices are simply displayed, the screen is not complicated, and it is possible to prevent the operator from being confused in selecting information. Further, since the number of 3D models handled simultaneously in the virtual world can be reduced, the load on the central control unit can be reduced.

Embodiment 4 In the third embodiment, 3
Although the D models are managed hierarchically and the degree of detail of the display of the 3D model is switched, in the fourth embodiment, a plurality of 3D models having different degrees of detail for one device are managed by the 3D data management unit 1. The 3D model to be displayed is switched according to the distance between the worker and the device. For example, when a bushing is represented by a 3D model, a detailed 3D model expressing individual insulators as shown in FIG.
When the distance between the viewpoint position of the worker and the 3D model of the device is short, the detailed 3D model shown in FIG. 4- (1) is displayed, and when the distance is long, Displays the simplified 3D model of FIG. 4- (2). As described above, the same effect as in the third embodiment can be obtained.

Embodiment 5 In the third embodiment, 3
Although the D model is managed hierarchically and the degree of detail of the display of the 3D model is switched, in the fifth embodiment, a detailed 3D model, a simple 3D model, and an image of the 3D model are displayed for one device. The data is managed by the 3D data management unit 1, and the 3D model to be displayed is switched according to the distance between the worker and the device.

For example, when the control panel is represented by a 3D model, as shown in FIG. 5A, in addition to a detailed 3D model composed of a control panel main body, switches, meters, and the like, FIG.
A simple 3D model in which the control panel body is represented by one rectangular parallelepiped as in (2) and image data when the control panel is viewed from the front are prepared. When displaying with a simple 3D model and image data, as shown in FIG.
Paste the image data on the surface of the model and display it. In this case, since the detailed 3D model is composed of a group of 3D models for each part, the operation of the device can be expressed, but the operation of the device cannot be expressed by a simple 3D model and image data. . Therefore, when the device operates in the ongoing inspection scenario, the device is displayed in a detailed 3D model.

The 2D drawing data is extracted from the 2D data management unit 9 based on the link to the drawing data, and a translucent 2D drawing (in the example of FIG. 7, a cross-sectional view 7-4 in the example of FIG. 7) is displayed on the front of the 3D model display. Is displayed. In this case, the size of displaying the 3D model 7-1 on the display device 6 varies depending on the distance between the 3D model and the viewpoint position. Therefore, the size of displaying the 2D drawing is adjusted according to the size of the 3D model to be displayed. And display. Further, when the viewpoint position of the worker overlaps with another vector (in the example of FIG. 7, the viewpoint position 7-5 of the worker overlaps with the vector 7-6 in the viewpoint direction), similarly, the 2D drawing ( In the example of FIG. 7, the skeleton diagram 7-7) is converted to 3D.

Embodiment 7 In the seventh embodiment, when the 2D drawing is displayed in a manner superimposed on the front surface of the display by the 3D model in the sixth embodiment, the viewpoint position of the worker does not overlap with the vector in the viewpoint direction for displaying the 2D drawing data. Even in this case, when the viewpoint position is in the space on the same side as the vector, the display size of the 2D data when the viewpoint position is on the vector is reduced and displayed.

Specifically, as shown in FIG. 8, when displaying a 2D drawing 8-3 in which the vector in the viewpoint direction is 8-2 by superimposing the 3D model 8-1 on the 3D model 8-1, the viewpoint position is set on the vector. If the position 8-4 is shifted laterally, the original 2
Display the projection of the width of the D drawing on the 8-5 plane. Similarly, when the viewpoint position is shifted in the vertical direction, the image is reduced. If the viewpoint position is shifted to the oblique position, both the horizontal reduction and the vertical reduction are performed. This allows the worker to superimpose and view the 2D drawing from an arbitrary position when performing a virtual experience of the patrol work.

Embodiment 8 FIG. In the eighth embodiment, when a 2D drawing is superimposed and displayed on the front surface of a 3D model display in the sixth embodiment, the transparency of 2D drawing data to be displayed is set to 100% (display) in response to a worker's request. The transparency of the data to be displayed is continuously switched from 0% (only the 2D drawing is displayed. The display of the 3D model is hidden by the display of the 2D drawing). Accordingly, when the worker virtually experiences the patrol work, the operator can simultaneously select and watch a display method that he wants to pay more attention to while superimposing and viewing the 3D model and the 2D drawing.
