Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to a simulator that simulates a control panel for driving training.
The present invention relates to a plant simulator having a function of simulating an actual plant in accordance with the operations of an instructor using a control panel controlled by a computer, and controlling the progress of the simulation from an instructor console.

Technical background of the invention and its problems In recent years, in various fields such as power generation, operators have been
The demand for plant simulators is increasing, and plant simulators generally store past operation data for a certain period of time (for example, 30 minutes) to enable repeated operation. However, some of the stored operation data includes data that is not necessary for repeated operation, such as data due to incorrect operations by trainers, etc., so there is less data necessary for repeated operation. Furthermore, if you try to operate the machine repeatedly, unnecessary data such as data from erroneous operations will be repeated.

FIG. 1 is an example of reproducing the state of a simulated plant from the past 10 minutes. In the figure, the sections O-A, B-1) and E-F are model operations by the instructor, and the others are malfunctions by the trainees. In this way, in conventional plant simulators, all operational data is always taken into consideration, so when trying to repeatedly conduct training from σ to F, the data between A and B, D and
Since data that does not need to be trained between E and E is repeated repeatedly, the burden on the operator is heavy and the efficiency is poor.

Purpose of the Invention The present invention provides a data storage switch on the instructor's console, and saves only the state of a simulated plant that is a model of the operation behavior by operating the switch, and prevents repetition of erroneous operations by the instructor. By making it possible to specify not to save unnecessary data during the 111th training, only the state of the simulated plant used as a model operation can be reproduced, eliminating unnecessary actions by instructors, and providing training for all trainees. The purpose is to provide a highly effective simulator device.

Summary of the Invention The present invention comprises a simulation board operated by an operator trainer, an instructor console through which the instructor specifies training items, and an electronic computer that inputs the state of the simulation board, simulates the functions of the plant simulation device, and outputs the results to the simulation board. 1, which is a plant operation training simulator equipped with an input/output device for inputting the state of the mock board and outputting it to the mock board, and simulating the plant based on the state of the mock board input by the input/output device. It also has an arithmetic and control unit that stores the simulation content in the simulation content storage area, and further stores the data in the simulation content storage area in the driving data storage area depending on the state of the driving data storage switch on the instructor's console. Only when specified by operating the operation data storage switch, the data temporarily stored in the simulation content storage area can be saved in the operation data storage area so that the data can be repeatedly practiced. Do not save unnecessary content in the training course that was conducted, save only what is necessary for re-training, and select from among these according to the needs of the time and reproduce it. So1
It is characterized by being successful in just one practice.

EMBODIMENT 1 OF THE INVENTION The present invention will now be described with reference to an embodiment shown in FIG. The simulated control board 1 has the same type and function as the control panel of the actual plant, and the trainees can grasp the state of the plant through the lamps, indicators, etc. of this simulated control board 1, and also use the simulated control board 1 Operation is performed using various operation switches.

The input/output device 3 transfers the operations from the simulated control panel 1 of the -11 training and the instructor's commands from the instructor console 2 (as No. g) to the arithmetic and control device 4. , the operation numbers from the till trainees and command number 16 from the instructor are inputted through the input/output device 3, and a simulation calculation of the control device function in the actual ground is performed.The calculation results are sent through the input/output device 3. The output 9 is displayed as a display signal on the simulated control panel 1 and the instructor's console 2.

The arithmetic control device 4 stores the operation signals of the simulated control panel 1 and the command signals of the instructor console 2, which are inputted by the input/output device 3, in the storage area 5.

Furthermore, the arithmetic and control unit 4 checks the state of the driving data storage switch 7 on the instructor console 2, which is input to the input/output device 3, and if the state of the driving data storage switch 7 indicates a storage request, the storage area is 5, the operation data is extracted and saved in the operation data storage area 6, and if the operation data storage switch 7 indicates a request to interrupt the storage, the above process is interrupted.

FIG. 4 shows the functions of the arithmetic and control unit 4 in a flowchart. Based on this FIG. 4, the operation of the present invention will be specifically explained using the functional block diagram of the arithmetic and control unit 4 shown in FIG. The operation signal from the simulated control panel 1 and the command signal from the instructor console 2 are read into the input/output function unit 43 in the arithmetic and control unit 4 via the input/output device 3 (a), and the input/output function unit 43
The data is saved in the input data section 51 in the storage area 5 (P).

Whether or not the data temporarily stored in the input/output data section 51 is stored in the driving data storage area 6 is determined by checking the 0N10FF state of the driving data storage switch 7 on the instructor's console 2 via the input/output device 3 to the arithmetic and control unit. 4 is controlled.

Referring to FIG. 5, the operation of the present invention, that is, the operation from when the operation data storage switch 7 is pressed until the operation data temporarily stored in the storage area 5 is saved to the operation data storage area 6 will be explained. . For example, as shown in Figure 3 (1),
When retraining is performed in the plant state up to time t0, by pressing the operation data storage switch 7 at time t0, the input/output device 3 receives and receives the control signal Ct for storing the operation data. is sent to the data storage switch designation unit 42 (hereinafter referred to as the SW designation unit) in the arithmetic and control unit 4 (c).

The SW designation section 42 which receives this control signal Ct sets the value of the save selection designation switch data section 53 (hereinafter referred to as SW data section) to 1. At this time, the data of the data storage request time (that is, corresponding to to in this example) is sent to the input/output device 3 along with the operation data storage control signal Ct.
The data is read from the input/output function section 43 and stored in the input/output data section 51. Therefore, the input/output function section 43 refers to the SW data section 53, and if the value is 1, it is determined that it is a storage request, and the time t, which was temporarily stored in the input/output data section 51. Extract the operating data corresponding to the
The data is sequentially stored in the operation data storage area 6 via the input/output function section 43 (e).

In addition, in the case of data that does not need to be saved, such as due to operator's incorrect operation, for example, time 1 in (1) of FIG. If you do not want to save the operation data between -12 and between times t and t4, turn off the operation data save switch 7 between times t and t1 and between times t3 and t4, and control the interruption of data storage. The signal Ct is notified to the SW designation unit 42 in the arithmetic and control unit 4 via the instructor console 2 and the input/output device 3 (
c). In this control signal, the SW designating section 42 sets the value of the SW data section 53 to zero. The input/output function section 43 refers to the value of the SW data section 53, and if it is 0, it is determined that it is a storage interruption request, and the data is not extracted from the people count data section 51, and the data is saved in the operation data storage area 6. I have nothing to do.

That is, the time t when the operation data storage switch 7 was turned off.
The operation data between 1 and t2 and between times t and t4 will not be stored in the operation data storage area 6.

By operating the operation data storage switch 7 in this way, the operation data that is eventually stored in the operation data storage area 6 among the plant states from time t0 to time tll reproduced in (1) of FIG. is as shown in θV) in FIG. In this way, by operating the operation data storage switch 7, it is possible to repeatedly save only the data necessary for the edge line.
When attempting to carry out repeated training, past driving data will no longer be repeated nine times.

In addition to providing the driving data storage switch as described in the above embodiment, it is also possible to specify the data to be saved through communication between the operator and the instructor console, and also to specify the data to be saved, not just for model driving. It is also possible to specify data that you do not want.

Effects of the Invention As mentioned above, according to the present invention, the responsiveness to erroneous operation by the operator is good, the instructor does not have to repeat unnecessary movements, and the model operation can always be reproduced. This eliminates time loss and provides a highly effective training simulator.

In particular, if an operator makes an important mistake during training, the subsequent operation data will be meaningless, but the operator makes many simple mistakes and would like to retrain for each of them. If 1,
By providing the operation data storage switch described in the present invention, there is an effect that retraining can be performed without destroying each data.
