Next, a processing procedure in the conventional example will be described with reference to FIGS. FIG. 8 is a flowchart showing a processing procedure in the conventional example.

[0008] The information output from the input device 5 is supplied to an analyzing means 61. The analysis unit 61 refers to the part information storage unit 71 based on the information input from the input device 5,
An analysis of the operation contents that the operator wants to operate is performed (step B1).

The retrieval means 62 retrieves the current display state of each part displayed on the display device 8 with reference to the display state table 65 (step B2).

The evaluation means 63 stores the part information storage 71 based on the information output from the input device 5 and the information of the part operated by the operator and the current display state obtained by the analysis means 61 and the retrieval means 62. By referring to the display state, the display state of the part operated by the operator after the display change is obtained (step B3).

, The display information of all parts is obtained, the display state table 65 is updated (step B4), and the display information is further output to the display device 8 (step B5).

Next, a specific simulation example of the conventional example will be described. FIG. 9 is a diagram showing a display example of the device simulation. In the figure, units A, B, and C are devices having a self-diagnosis function, and it is now assumed that unit A is out of order.

In this case, as a maintenance training simulator,
Consider the following two simulation examples. However, for simplicity, only one simulation example will be described. (1) When both the power switch and the diagnostic switch are turned on, the unit A has failed and the NG-A lamp of the diagnostic result is turned on (FIG. 9 (2)). (2) When the unit A is replaced with a normal one, if the power switch and the diagnostic switch are both turned on, the OK lamp of the diagnostic result is turned on (FIG. 9 (4)).

Here, the input device is a mouse. When the mouse is left-clicked on the power switch and the diagnostic switch, it indicates that each switch is turned on / off, and the replacement target site (units A to C) is a mouse. If you right-click, you will replace it with a normal one.

When the operator presses the left button of the mouse on the diagnostic switch in the state shown in FIG. 9A, the power switch is turned on and the diagnostic switch is turned on.

The analysis means 61 refers to the part information storage section 71 from the information on the position from the input device 5 (mouse) (see FIG. 10 for details), and from the information on the position, finds out where the operator wants to operate. A part to be operated (a diagnostic switch in this example) is obtained.

The search means 62 obtains the current display state of each part displayed on the display device 8 by referring to the state table of the display state table 65 (for details, see FIG. 11A).

The evaluation means 63 includes information on the click from the input device 5 (in this example, the left button is pressed) and information on the current display state of the diagnostic switch obtained by the search means 62 (in this example, the state “OFF”). ), The state after the display change of the diagnostic switch, that is, the state “ON” is obtained from the display state change condition by the operation of the operator with reference to the part information storage unit 71 (FIG. 10).

The display control unit 64 refers to the display state information storage unit 72 (FIG. 12) based on the information obtained by the search unit 62 (FIG. 11A) and the information obtained by the evaluation unit 63, and performs a diagnosis. The display state table 65 is updated by obtaining the changed state of the display of all the parts by changing the switch from “OFF” to “ON” (FIG. 11B), and the display information is output to the display device 8.

By the above simulation, the display result of the display device 8 is as shown in FIG.

When it is desired to simulate the operation of a device having a different failure site (for example, the unit B has failed), the information stored in the display state information storage unit 72 is changed to a state that can occur at the time of the failure site. It can be changed each time and can be performed by the same processing as described above.

Further, as a simulator similar to the above-mentioned prior art, there is a conventional example disclosed in Japanese Patent Application Laid-Open No. 63-158584. This conventional example is a training simulator used for training trainees in plant operation.

FIG. 13 is a block diagram showing the configuration of the plant operation training apparatus described in this publication. The configuration of the device and its operation will be briefly described. The instructor console 9 sets plant conditions (initial state, failure state, etc.) necessary for the instructor to simulate the plant according to the contents of the operation training. The initial state setting device 10 notifies the plant model 12 of the set initial state. The malfunction setting device 11 notifies the plant model 12 of the set fault state. Plant model 1
2 simulates a plant state based on the input plant conditions. The failure display device 13 performs alarm display and the like as in the case of the actual plant.

The trainee operates the interactive console 15 of the plant information storage device 14 in order to consider a countermeasure against a failure by displaying the failure display device 13. The plant information storage device 14 stores information on field devices in various plant states, reads out information corresponding to the state simulated by the plant model 12, and displays the read out information on the CRT display device 16.

The trainee displays the simulation operation panel 17 on the display.
The plant model 12 is simulated in accordance with the operation and displayed on the failure display device 13, and it can be determined from the display whether the operation just performed is appropriate.

[0026]

The prior arts so far have the following problems.

The first problem is that when trying to simulate the device, the more complicated the device, or the more complicated the failure location, the more difficult it is to create display state information. Met. The reason is that the state information of the device to be simulated must be listed for all of the normal state and the failure state.

The second problem is that a large number of man-hours were required to perform another failure simulation. The reason is that display state information (as shown in FIG. 12) must be newly created every time a failure is simulated.

In view of the above-mentioned problems of the prior art, an object of the present invention is to prepare a normal state information in advance when simulating a failure of a device in a maintenance training simulator so that a normal operation can be simulated. In order to simulate the failure, it is necessary to prepare the part information of the failed part and the part affected by the failure, and to simulate the failure by exchanging the part information with the part information in a normal state.
