[0006]

[Problems to be Solved by the Invention] However, the above-mentioned driving training simulator device has the following problems.

[0007] In other words, the conventional operator training simulator device is installed independently of the actual plant, and the emphasis of education is placed only on plant operation training. On the other hand, for the inspection and maintenance of the control device 7(n) of the actual plant, a dedicated simulated signal generator 10(n) is used for operation training to individually inspect and maintain the control device 7(n). Maintenance training was also conducted separately. For this reason, training for plant operation and maintenance was redundant, and equipment dedicated to each was redundant.

In particular, today's plants are large, and the control devices of actual plants are distributed microcomputers, and each device is also becoming more sophisticated. Maintenance and inspection of these devices has become complicated, and the specialized knowledge and education of maintenance personnel has also become an important issue. Such plants have a problem in that both plant operation training and maintenance training require advanced training and a large amount of training time.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an operation training simulator device that can improve the efficiency of plant operation training and maintenance training and reduce the amount of equipment required.

In the operation training simulator device connected to the control device of the actual plant via the actual plant network, the operation panel includes a changeover switch that outputs a switching signal for switching to the operation training simulator side or the actual plant side. The simulator computer includes a transmission memory for exchanging and storing data with the dynamics simulating means;

A buffer switching means for switching to the transmission buffer side when it is on the plant side is provided.

[0011]

[Operation] With the above configuration, the operation signal from the driving training simulator device is inputted to the control device of the actual plant, and the output signal from the control device is inputted to the driving training simulator device, thereby checking the state of the control device of the actual plant. It can be verified. Therefore, the operation training simulator allows maintenance and inspection of the control device of an actual plant, as well as education and training. Furthermore, since the simulation signal can be generated from the driving training simulator device, a simulation signal generation device dedicated to each control device is not required, and the amount of equipment can be reduced.

It is equipped with

The changeover switch 14 generates a changeover signal for switching between the driving training simulator side and the actual plant side.

The switching signal detection means 15 detects the switching signal.

The memory switching means 16 switches the dynamics simulating means 4 to the inter-simulation means memory 5 side if the switching signal of the switching signal detecting means 15 is from the driving training simulator device, and if the switching signal is from the actual plant side, If so, switch to the transmission memory 17 side.

The transmission memory 17 stores data from the dynamics simulating means 4 and stores data transmitted from the transmission buffer 22.

The transmission line 18 connects the transmission memory 17 of the driving training simulator device and the actual plant network 9 of the actual plant.

The switching signal detection means 19 detects the switching signal of the changeover switch 14.

The buffer switching means 20 switches to the PI/O buffer 21 if the switching signal is from the driving training simulator device, and switches to the transmission buffer 22 if the switching signal is from the actual plant side.

The PI/O buffer 21 stores process input/output data when the switching signal is on the driving training simulator side.

The transmission buffer 22 stores data from the control device 7(n) when the switching signal is on the actual plant side, and further stores data from the transmission memory 17.

Note that 23 and 24 indicate signal lines that are switched by the memory switching means 16 or the buffer switching means 20, and the transmission memory 17 and the transmission buffer 22
A transmission means for exchanging data between the actual plant network 9 and the actual plant network 9 is not shown.

[0025] With the above configuration, in normal times, that is, when the changeover switch 14 is on the driving training simulator side, the dynamics simulating means 4 is connected to the inter-simulating means memory 5 side in the driving training simulator apparatus.

[0026] In the driving training simulator device, the operation panel 1
When the operation switch 2 is operated to output an operation signal to the simulator computer 3, the dynamics simulating means 4 calculates state quantities and physical quantities according to the operation signal. Alternatively, the state quantities and physical quantities calculated by the dynamics simulating means 4 are used to calculate a control state according to the plant state by the control device simulating means 6(n).

These calculations are stored in the simulation means memory 5 and displayed on the display device of the operation panel 1 as simulation data.

In this way, plant operation training is performed for each item of each control device by simulating an actual plant using the operation training simulator.

Note that the driving training simulator device stores data such as the output of the control device, the opening degree of the valve, pressure, temperature, etc. for each training stage. The control device simulating means 6(n) starts the training after setting the control device output, valve opening, pressure temperature, etc. suitable for the plant state where the training is to be performed.

Furthermore, when the control device 7(n) of the actual plant is operated from the driving training simulator, it is necessary to match the output of the control device to the state of the plant to be operated. For this purpose, the output of the control device stored in advance in the driving training simulator device is transferred to the actual plant network 9.
A process of transmitting the data to the control device 7(n) of the actual plant is performed.

In the actual plant, the detection signal of the sensor 11(n) is inputted via the PI/O 12(n) to the control device 7(n) of each actual plant distributed by the actual plant network 9, and the control unit 13 (n) is operated to control each process amount, etc.

Next, when the changeover switch 14 is switched to the actual plant side, a switching signal is output from the operation panel 1 to the simulator computer 3 and the actual plant. Accordingly, in the simulator computer 3, the switching signal detection means 15 detects the switching signal, while in the actual plant, the switching signal detection means 19 of the control device 7(n) detects the switching signal. The memory switching means 16 of the simulator computer 3 is switched to the transmission memory 17 side by the detection signal of the switching signal detection means 15. Thereby, the data of the simulator computer 3 is stored in the transmission memory 17.

On the other hand, the buffer switching means 20 of the actual plant
is switched to the transmission buffer 22 side by a switching signal from the switching signal detection means 19. Thereby, the data of the control device 7(n) of the actual plant is stored in the transmission buffer 22.

In this way, the changeover switch 14 on the operation panel 1
By switching to the actual plant side, the driving training simulator device stores the internal data of the driving training simulator device in the transmission memory 17, and the actual plant side stores the internal data of the actual plant in the transmission buffer 22.

Here, the operation switch 2 of the operation panel 1 is provided corresponding to the control device 7(n) of the actual plant, and a display section is further provided corresponding to the control device 7(n) of the actual plant. There is.

First, an operator, for example, operates a certain control device 7.
When (i) is specified and the corresponding operation switch 2 is operated to open the solenoid valve, this operation signal is stored in the transmission memory 17 of the simulator computer 3. Furthermore, this operation signal is stored in the transmission buffer 22 to the corresponding control device 7(i) of the actual plant via the actual plant network 9. The control device 7(i) of the actual plant reads the data in the transmission buffer 22. Then, the control device 7 (i
) performs a control operation to open the solenoid valve, while data on the control state for opening the solenoid valve is stored in the transmission buffer 22 from the control device 7(i). Subsequently, this control state data is transferred from the transmission buffer 22 to the transmission memory 1 of the simulator computer 3 via the actual plant network 9.
7 and stored.

The control state data stored in the transmission memory 17 is read into the dynamics simulating means 4. The dynamics simulating means 4 calculates various physical quantities such as pressure and temperature based on the data read into the dynamics simulating means 4. The calculation results of the dynamics simulating means 4 are displayed on the display device of the operation panel 1.

Similarly, suppose that, for example, the setting value of a certain control device 7(i) which is under automatic control is changed from the operation switch 2 of the operation panel 1. In this case, the corresponding control device 7 (
Data is input/output between i) and the dynamics simulating means 4. That is, a signal for changing a set value is input to the control device 7(n), and a deviation value, an output value, etc. are output from the control device 7(i) to the dynamics simulating means 4 as data. As a result, the dynamics simulating means 4 controls the control device 7 (
The physical quantities of the controlled object are calculated from the various data in i), and the control device 7(i) of the actual plant is verified from the results.

As described above, in this embodiment, the operation training simulator device is connected to the control device 7(n) of the actual plant via the actual plant network 9, and the operation training simulator device is connected to the control device of the actual plant. The control state of the control device of the actual plant is calculated by the simulator computer 3 by transmitting the operation signal of the simulator device, and the plant can be inspected. Therefore, there is no longer a need for a dedicated simulator for maintenance and inspection of actual plants, as was the case in the past.

Furthermore, the operation training simulator device of this embodiment allows not only inspection and maintenance of the control device, but also functional tests of the control device by incorporating simulations in various plant conditions that were not possible with conventional dedicated simulators. . Therefore, maintenance and inspection of the control device can be performed efficiently, reducing the workload and periodic inspection period. What's more, maintenance training can be provided in addition to driving training, making this training more efficient.

Next, FIG. 3 shows another embodiment of the present invention.

This embodiment utilizes the fact that the driving training simulator device is connected to the actual plant network 9. When the driving training simulator device is not used for education or the like, various operating data outputted from the actual plant to the host computer 8 are inputted into the driving training simulator device. A switching signal from the changeover switch 14 switches the switching means 26 to the actual plant side. Then, the data in the ideal operating data storage means 25 stored in advance is compared with the operating data of the host computer 8, and the result is displayed on the display section of the operation panel 1 as display data. In this way, plant efficiency, operating technology, etc. can be evaluated.

[0043]

As described above, according to the present invention, inspection and maintenance of a control device of an actual plant can be carried out using an operation training simulator device. Therefore, there is no need for a dedicated simulator in the actual plant, and equipment can be reduced. In addition, the operator training simulator equipment not only allows for inspection and maintenance, but also enables efficient functional testing of control equipment under various plant conditions, which shortens periodic inspection periods and greatly improves plant reliability. You can get the effect of improving.
