Embodiments of the present invention will be described below with reference to FIGS. 1 to 6 show a first embodiment in which an embodiment of a plant operation history monitoring simulator for carrying out a plant operation history monitoring simulation method of the present invention is applied to a central control unit of a nuclear power plant. ing.

The plant operation history monitoring simulator of this embodiment has a plurality of simulated control boards 2, a computer 4, and an instructor console 3, as shown in FIG. Is operated, the series of operation history information is displayed and printed on the instructor console 3 in time series by the computer 4.

Each simulated control board 2 has a plurality of hard switches 21 provided on the board surface, each having a display section (not shown), or a soft switch 22 provided on the board surface.
Each of them has a display unit, and each of them is a simulated control panel for plant operation installed in the central control room of the nuclear power plant. Although not shown in detail, when the hard switch 21 is operated, an indicator as a display unit is activated or an indicator light is turned on. A plurality of soft switches 22 are provided on a display unit such as a flat display or a CRT for touch operation. When operated, the display unit operates according to the contents thereof. Each of these simulated control boards 2 is installed in the training room and operated by the operator 1 of the simulator.

Here, the relationship between the operator 1 and the simulated control panel 2 will be described. When the simulated control panels 2 include four units 201 to 204 as shown in FIG. 3, for example,
Each of them will be sequentially operated by four operators 1a to 1d. And the driving training, as shown in FIG.
A series of flows consisting of initial state setting 100 of simulator → start 101 of simulator → training 102 → stop 103 of simulator is set as one training case, and by repeating this, various training cases are performed respectively. At that time, the four operators 1a to 1d, with respect to the four simulated control boards 201 to 204, in the first training,
The operator 1a is in charge of the simulated control board 201, the operator 1b is in charge of the simulated control board 202, the operator 1c is in charge of the simulated control board 203, and the operator 1d is in charge of the simulated control board 204. Training with. After that, as shown by an arrow in FIG. 3, the simulated control boards 201 to 204 are sequentially replaced, that is, the operator 1a operates from the simulated control boards 201 to 20.
2, the operator 1b is from the simulated control panels 202 to 203, the operator 1c is from the simulated control panels 203 to 204, and the operator 1d is
By retreating from the simulated control panel 204 to 201,
By shifting from the training case 1 to the training case 2 and repeating this, all the operators can perform all the simulated control panels 201.
Rotation is used for operating training of ~ 204.

On the other hand, when the hard switch 21 and the soft switch 22 of each simulated control panel 2 are operated by the operator 1, the computer 4 simulates the simulator as plant behavior based on the operated switches 21 and 22. The control is performed, that is, the operator 1 is controlled as if operating the actual plant.

The instructor console 3 causes an abnormality in the CRT display device 31 for displaying the operation contents of the simulated control panel 2, the printing device 32 for printing desired contents, the switch for controlling the simulator, and the simulator. The CRT display device 31 and the printing device 32 are provided with a switch means 33, which is a switch for performing a desired operation. The instructor console 3 is installed in the instructor room and handled by the instructor of the simulator.

The computer 4 will be described in detail. In the computer 4, when the operator 1 operates the hard switch 21 of the simulated control panel 2, the signal of the signal is input via the hard switch operation input device 5 to the operation information input process. Input to section 41,
When the operator 1 operates the soft switch 22 of the simulated control panel 2, the signal is directly input to the operation information input processing unit 41.

When the operation signal is input, the operation information input processing section 41 adds time information 411 at the time of the input, as shown in FIG. 4, for example, the date, hour, minute, second. This time information is added, and the added input signal is transmitted to the search / save processing unit 6 and the plant simulation unit 42, respectively. In this case, the plant simulation unit 42 simulates the behavior of the plant based on the content of the transmitted signal, and the operator and the indicator lamp of each simulated control panel 2 are as if the operator 1 were operating the actual plant. Etc. are controlled.
Therefore, the operation signals of the switches 21 and 22 are previously distinguished for each switch, and in this example, as shown in FIG.
Each switch is distinguished by a point number such as "DI001", "DI002" ....

On the other hand, the inspection / storing processing unit 6 has the switch 2 to which the time information is added by the operation information input processing unit 41.
When the operation signals 1 and 22 are transmitted, the operation signals are
Which switch of which simulated control panel 2 is used is determined. That is, as shown in FIG. 4, the inspection / save processing unit 6 has a search process 61 and a save process 62, and when the operation information input processing unit 41 sends an operation signal to which time information is added. The search processing 61 uses the point number of the operation signal as a search key to search the switch information database 7 for a series of information corresponding to the operation signal, and stores the searched series of information by the storage processing 62 by the operation history information storage means. Store in 8.

Here, as the series of information stored in the switch information database 7, as shown in FIG.
Point No7 for identifying any of the plurality of switches 21 and 22
a, the name 7b of the switch-operated target, the type (No) 7c of the simulated control panel 2 that was switch-operated, the type (No) 7d of the system, the switch tag No 7e, and the operation content 7f. , And are recorded in association with each other in advance.

Therefore, the search / save processing section 6 instructs the operation history information storage means 8 to correspond to the series of information 7a to 7f on the switch information database 7 as shown in the lower part of FIG. Based on, switch name 8b, panel No. 8c, system No. 8d, switch tag N
In addition to o8e and the operation content 8f, the added time information 8g is also stored. In this case, the time information at the time of the operation is stored as a base, and for example, as point No8a, "DI001", "DI003", "DI00"
5 ”,“ DI007 ”,“ DI002 ”, ... When the training such as the rotation described above is performed, the operation history information storage unit 8
As shown in FIG. 5, a series of information sequentially taken out each time the switches 21 and 22 are operated is stored variously as operation history information of one training case. The operation history information storage means 8 has a capacity for storing operation information for a predetermined number of days.

Further, the information stored in the operation history information storage means 8 is displayed on the CRT display device 31 of the instructor console 3 by the display / print processing unit 9, and the display contents are printed by the printing device 32 as necessary. I am trying to do it.

That is, the display / print processing unit 9 extracts a series of operation history information, which is sequentially extracted each time the switches 21 and 22 of each simulated control panel 2 are operated, from the operation history information storage means 8, The CRT display device 31 of the instructor console 3 is displayed in chronological order with the contents of the operation history information storage means 8 shown in FIG. 4, and the displayed operation history information is printed by the printing device 32 in response to a request from the instructor console 3.
Is printed.

In the display / print processing unit 9, the instructor selects the "operation panel selection" key (not shown) of the instructor console 3, and the display processing 91 is performed as shown in FIG. ], Board No. "202" in Training Case 2, Board No. "20" in Training Case 3
3 ”and the panel No.“ 204 ”in the training case 4 are designated, the CRT display unit 31 sequentially displays the necessary information with the time added, as shown in the lower part of FIG. The operation history of only the operator 1a can be displayed and printed.

Further, the instructor console 3 selectively displays and prints not only the operation history of each control panel but also the operation history of each system of the plant and the operation history of each of the switches 21 and 22. I am trying. In this case, the time information is always displayed.

Further, the display / print processing unit 9 is also adapted to automatically select and display / print the most used pattern on the CRT display device 31 of the instructor console 3. That is, when the instructor operates the “display” key 311 in FIG. 5, the display / print processing unit 9 causes the CR
On the screen of the T display device 31, the operation history information up to now is displayed as shown in the form of overwriting the request setting screen.

For example, the operation history information so far is displayed in the order of the latest data, and the training date 31a, the type of training case (training case) 31b performed on that day, and the type of control panel are displayed in the order of data. A control panel selection 31c for enabling selection and a system selection 31d for enabling selection of each system type are respectively displayed. In this case, the last two digits of the year and its month and day are displayed in the field of training date 31a, and the type of training case is added to the field of training case 31b in addition to the operation information input processing unit 41. The time information is displayed.

Moreover, an operation history information summary 31e is displayed under the latest operation history information order. The outline 31e of the operation history information is such that when a specific type of training case is selected by the operation of the instructor and the cursor is positioned at the selected specific type of training case locations 31a to 31d, the specific type of training case is displayed. The outline of the operation history information of is displayed. Therefore, the CRT display device 31 has a display key 311 on the screen for automatically selecting the most used pattern.

Further, on the screen of the CRT display device 31, as shown in FIG. 6, there is provided a print key 312 for printing the information displayed on the screen by the printing device 32, which is further displayed on the screen. In order to display the specific contents selected from the detailed information in detail, it also has a continuation key 313 capable of continuously executing and displaying the detailed information. And FIG.
When the continuation key 313 is pressed and a desired one is selected, the operation history information of the selected desired training case is displayed in time series. Alternatively, when a plurality of training cases are selected and a different control panel and system are selected for each training case, the plurality of training cases can be displayed simultaneously. In addition, the above information can be displayed on the screen of the CRT display device 31 as necessary, and the display content when the driver 1 specifies it can also be displayed as needed.

Since the plant operation history monitoring simulator of the embodiment is constructed as described above, one embodiment of the method of the present invention will be described with reference to its operation. For example,
As shown in FIG. 3, the operator 1a attaches the simulated control panel 201 to the
The operator 1b is in charge of the simulation control panel 202, the operator 1c is in charge of the simulation control panel 203, and the operator 1d is in charge of the simulation control panel 204, and these are operated to perform the training case 1. As shown by the arrows, the operators 1a to 1d sequentially operate the simulated control panels 201 to 204 to sequentially execute the training cases 3, 4, ...

In the above training case, the simulation control board 20
1 to 204 are operated, the operation information input processing unit 41 of the computer 4 adds the time information 43 at the time of the operation for each operation signal of the switches 21 and 22, and the operation to which the time information 43 is added Signal search / save processing unit 6 and plant simulation unit 4
2 respectively. As a result, the plant simulation control unit 42 simulatedly controls the simulator as a plant behavior based on the contents of the operated switches 21 and 22.
The inspection / storing processing unit 6 retrieves and retrieves a series of information from the switch information database 7 based on the transmitted operation signal of the switch 21, and retrieves the series of information as operation history information storage means. When stored in 8, display
The print processing unit 9 displays the series of information on the CRT display device 31 of the instructor console 3. The displayed series of information can be printed as needed by the switch 33 of the instructor console 3.

Therefore, the instructor can analyze the operation content of each simulated control panel 2 by the specific operator 1a to 1d according to the content. In other words, since each simulated control panel 2 can specify the operator 1a to 1d who operates the simulated control panel 2 according to the type of training case, the operation history of the specific operator 1a to 1d can also be known.

Moreover, the display / print processing section 9 is operated by a switch from the instructor console 3, and as shown in FIG. 5, the board No. of the first simulated control board 201 in the training case 1 and the simulation in the training case 2 are simulated. Panel N of control panel 202
