DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driving support system for a power system monitoring and control system using a head mounted display.

[0002]

2. Description of the Related Art In a power system monitoring and control system,
Driving operation differs depending on the operator's experience and judgment. Therefore, a dedicated guidance screen or the like is displayed on a display on the control console as driving assistance.

Normally, sufficient operation training is required for the operation of the power system monitoring and control system, and how to deal with the occurrence of an accident often depends on experience. For this reason, driving assistance is provided by displaying a guidance screen etc. on the display, but driving assistance using the guidance screen occupies one display of the control console, which can reduce the operation efficiency of the entire system There is. Even if this is realized by another device such as a personal computer, it is difficult to maintain the continuity of the operation while viewing the guidance screen. In addition, this method has a limitation in the output contents of the guidance because it is output based on character information, and is not suitable for providing detailed guidance according to the level of each operator.

Accordingly, the present invention solves the above-mentioned problems, and provides an operation of a power system monitoring and control system capable of ensuring continuity of operation without lowering operation efficiency and capable of performing fine and high-level operation training. The purpose is to provide a support system.

Observer 1 is a system A in real time.
Monitor and analyze the status of. When the observer 1 detects a change in the state of the system A serving as a guidance output trigger (step S11), the observer 1 sends a guidance output request to the guidance calculation unit 4 and provides information on the system A recognized by the observer 1 (S12). According to the data, the basic database 2 and the extended database for driving training support 12 are accessed via the database server 3 to formulate an optimal guidance plan (S13). The drafted guidance plan is notified to the man-machine control unit 5 and processed into each output data to the man-machine device D. The head-mounted display 7 displays a screen on which CGs such as guidance data are combined in addition to all the images that should originally be in the field of view.
The headphone device 8 outputs audio guidance or various alarms for assisting the image on the head-mounted display 7 (S14), and the operator performs each operation with reference to these. At this time, it is determined whether or not a command input has been detected (S15). If Yes, the process returns to Step S14. If No, the process returns to Step S11.

By using the video device C, it is possible to record or reproduce past operation results and simulation results at an arbitrary timing.
