Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a plant operation training simulator that can automatically carry out training calikilam.

[Technical background of the invention]

In recent years, the control systems of each device that makes up a plant have become more complex.
Training of operators who operate the above-mentioned plants is also becoming an important issue in terms of accident prevention.

In such a case, a separate driving training simulator is used to train the operators.

The training content includes normal operation training for plant start-up, operation, and shutdown, accident response W1 (practice) by creating a simulated accident (malfunction) during normal operation training, and repetition of important operational parts during plant operation. Repetitive training (pack truck), reflection on driving operations by replaying the responses of the trainee's operations without the trainer's operation, and stopping the driving training simulator at a certain point (freeze mode) ), high-speed driving (first mode) training to make the response speed of the same controller faster than usual for confirmation of operation, short-term repeated training, etc., and conversely, training for detailed operation There is training such as low-speed driving (slow mode), which makes the simulator's response speed slower than usual.

As shown in Figure 1, the plant operation simulator (hereinafter referred to as simulator) used for such training consists of a training control panel 1 from which the training instructor issues commands to control the simulator, and a training operation panel 1 from which the training instructor issues commands to control the simulator. A simulated operation panel 2 having the same operation surface as the actual plant operation panel to be operated, a simulated operation section 3 that performs simulated calculations of the plant state based on information from the simulated operation panel 2, and an initial value of this simulated operation section 3, It is comprised of a simulator control section 4 that controls boundary conditions such as start time based on commands from the teaching operation panel 1.

The simulator control section 4 includes an initial value setting processing section 5 that sets the initial value of the ground state before starting training in response to a command from the instruction operation panel 1, and an initial value setting processing section 5 that sets the initial value of the ground state before starting training in response to a command from the instruction operation panel 1, and a It has a plurality of training function processing units 6 corresponding to each of the above-mentioned trainings, which act on the calculation unit 3 to cause the calculation of the plant state during each training such as the above-mentioned malfunction and backtracking, or to stop the calculation.

Further, the simulator control unit 4 automatically records the calculation results of the plant state in each training session obtained by the simulation calculation unit 3 on the CRT device and pen recorder provided on the simulation operation panel 2 and the instruction operation panel 1, and It also has a function to record the operations performed by the trainee on the simulated operation panel 2 in a recording device provided on the instruction operation panel 1.

When training operators using a simulator having such an external configuration, an instructor first gives a command from the training operation panel 1 to the initial value setting processing section 5 in the simulator control section 4 as to which plant state to set. The initial value setting processing section 5 sets the designated initial value data from among the pre-stored initial value data group for the simulated computation to the simulated computation section 3 through the simulated computation control command. Next, the instructor instructs the corresponding training function processing unit 6 in the simulator control unit 4 from the instruction operation panel 1 as to which training curriculum to carry out among the training curriculums described above. For example, when conducting malfunction training, what state should the instruction panel 1 and other devices (e.g., motors, pumps, valves, etc.) be in (e.g., start, stop, 1:0, In addition, if it is a valve, the instruction as to whether it should be set (open, closed, etc.) is sent to the malfunction function processing unit 6n of the training function processing unit 6.
given to.

Malfunction machine AI': The processing unit 6n simulates the control command for the simulation calculation to change the data in the simulation calculation unit 3 in order to bring the specified equipment into the specified state according to the command. It is sent to the calculation section 3. The simulation calculation unit 3 that receives the above instruction for simulation calculation calculates the ground state based on the instruction and information from the simulation operation panel 2 operated by the trainee, and returns the calculation result to the above-mentioned malfunction function processing unit 6n. The malfunction function processing unit 6n sends the above calculation results to the instruction operation panel 1 and the simulated operation panel 2.
Display on a display device such as a CRT device. Further, when the malfunction training is to be completed, when a cancellation command is sent from the instruction panel 1 to the malfunction function processing section 6n, the malfunction function processing section 6n cancels the control command for the simulated calculation.

As described above, when implementing a certain training curriculum, each training function processing unit 6 issues a simulated calculation control command (in response to a command containing various information from the instruction panel 1) to control the simulated calculation. I try to do that.

61 [Problems with back bowl technology] However, the plant operation training simulator configured as described in Section 2 had the following problems.

That is, the initial value settings before training begins, the settings of each condition corresponding to each training curriculum after training begins (for example, the state settings of motors, pumps, etc. in malfunction training), and the start time of each of the above conditions, Setting of the end time, etc., was all carried out by the training instructor, who returned to the training operation panel 1 at any time while monitoring the operation, time, etc. of the driving trainee.

For this reason, the training instructor spends a lot of time at the training operation panel 1, and does not have enough time to instruct the driving trainers, which is his original duty.

Furthermore, when carrying out the same training curriculum, the training instructor has to perform the same operations on the instruction operation panel 1 many times, which greatly reduces complexity.

Furthermore, in some training curricula, the contents of the operations performed by the corresponding driving trainee may vary greatly depending on the start time, end time, etc. of the siding condition. therefore,
Training instructors were required to put in more effort and attention than necessary to measure the timing of each of the above times.

In addition, recently, in order to reduce the above-mentioned wasted labor of training instructors, a movable small operation panel has been installed separately from the above-mentioned instruction operation panel, and the training instructor can use the above-mentioned small operation panel while instructing driving trainees. Although it has been proposed to control the simulator by operating an operation panel, it is difficult to send complex commands to the simulator control unit 4 using the small operation panel.

As described above, the conventional simulator did not provide sufficient training effects.

[Purpose of the invention]

The present invention has been made based on the above circumstances, and its purpose is to automate the progress of training by providing a storage device that stores training schedules that vary depending on the content of the training curriculum. The object of the present invention is to provide a plant operation training simulator that allows instructors to spend more time teaching trainees, thereby making the training more effective.

[Summary of the invention]

In order to achieve the above objects, the present invention is characterized in that a control device for a plant operation training simulator is configured as follows.

That is, the control device corresponds to a storage device that stores training schedules that vary depending on the content of the training curriculum, and a training curriculum that is to be implemented from the training schedule in the storage device according to instructions from the instruction operation panel. a selection device for selecting a training schedule; a time setting device for setting the execution time of the training calikiram; a simulation calculation section for performing simulation calculations of the plow plant operating state based on information from the simulation operation panel; and a simulator control unit that instructs the simulation calculation unit to execute or stop the simulation calculation corresponding to the selected training schedule 9-schedule based on the commands from the training unit 9 and the signals from the selection device and the time setting device. ing.

[Embodiments of the invention]

FIG. 2 is a block diagram showing a plant operation training simulator according to an embodiment of the present invention, and the same parts as in FIG. 1 are given the same reference numerals. Therefore, the explanation of the overlapping parts will be omitted.

In the simulator of this embodiment, the contents of each training curriculum (for example, state settings of motors, pumps, etc. in malfunction training, timing of start and end times, etc.) are set in schedule table 7 for each training. It is stored in the storage device 8. Schedule table 7 above
Changes, deletions, and additions to the stored contents are performed in the schedule table access section 9 through the human-machine interaction information a.

Next, explanation will be given along the flow of signals. First, instruction control panel 1
In response to the schedule table selection command 6 from the storage device 8, the selection device 10 selects the specified schedule table 7 from the storage device 8, and sends a selection completion signal C to the timing monitoring section 11 when the selection is completed. . The timing monitoring unit 11 monitors the start and stop times of the training curriculum stored in the selected schedule table 7, and sends a timing establishment signal d to the simulated command generation unit 12 at the set time. send. This simulated command generation unit 12 sends the simulated command e written in the memory contents of the schedule table 7 to the training function processing unit 6 corresponding to the training calikilam to be executed in the simulator control unit 4 with the timing controlled. send to The training function processing unit 6 that has received the simulation command e executes the simulation calculation unit 3 as described above.
Calculate the plant status and display the results on the instruction control panel 1.
and displayed on the simulated operation panel 2.

It should be noted that commands f can be directly sent from the teaching operation panel 1 to the selection device 1o, without going through the timing monitoring section 11, etc., to the mirator control section 4.
It is also possible to feed and drive.

As shown in FIG. 3, the schedule table 7 stores data 1 to n representing the start time, stop time, characteristics, definition, etc. of each training curriculum for each training curriculum. Note that the timing of the above start time and stop time can be specified by time, by a signal from the instruction operation panel 1 (for example, the designation is a button operation), by the plant state becoming a certain specific state, or by one more method. Alternatively, it is also possible to determine by designation using a plurality of AND and OR circuits.

With a simulator with such a configuration and operation, when a training instructor trains according to a training curriculum, he or she only needs to give a command to select a schedule table of the training curriculum to be carried out from the training operation panel 1 to the selection device 10. Then, the training curriculum is automatically carried out according to the procedures stored in Schedule Table 7. Therefore, the training instructor does not need to input various commands from the training operation panel 1 once the training curriculum has started, so that he or she can secure enough time to instruct the driving trainee. the result,
Able to conduct effective training.

In addition, in the embodiment, the simulator control unit 4 is configured to be driven directly by the command f from the instruction operation panel 1, so that the schedule table 7 can be changed by operating the instruction operation panel 1 while the training calikiram is being executed. It is also possible to perform any training development without changing the content.

Therefore, the training effect can be further improved by appropriately changing the training curriculum depending on the trainee's training acquisition status.

Note that the present invention is not limited to the embodiments described above. That is, since the training curriculum is automatically carried out simply by sending a schedule selection command from the teaching operation panel 1, there is no need to send complicated commands from the instruction operation panel 1 to the simulator control section 4. Therefore, by providing the above-mentioned movable small operation panel and simply sending a schedule selection command from this small operation panel, it is also possible to carry out a complex training calikiram.

13- In this case, the training instructor does not have to leave the operator trainer at the simulated operation panel 2, so the training effect can be further improved.

〔Effect of the invention〕

As explained above, according to the present invention, when a training schedule corresponding to the content of each training curriculum is stored and the training curriculum is executed, the training curriculum is executed according to the stored training schedule. Therefore, it is possible to significantly reduce various simulator control operations performed by training instructors in conventional simulators. Therefore, the training instructor's direct instruction time for the driving trainee can be significantly increased, so that the training effect can be improved.
