2. Description of the Related Art Conventionally, a plant simulator is an apparatus for simulating an actual machine plant for a specific plant, but it has been used alone as a separate body from the actual machine plant. The equipment configuration of this type of general simulator is shown in FIG.

In the simulator training, an operator operation input signal on the simulator control panel 3 is transmitted via an input / output card (simulator input / output card) 6 and an input / output computer (simulator input / output computer) 7. , The plant model unit 1 which is also processed by the input / output interface unit (simulator) 8 provided in the simulation computer 1B and which is realized by the software module and which is also realized by the software module as the external change boundary condition.
0, the simulation result is CRT
The data is supplied to the computer (display controller) 5 and displayed on the CRT (display device) 4 of the simulator control panel 3 in time series.

[0005]

As described above, the conventional plant simulator faithfully simulates an actual plant, and has been realized and used as a single system for a specific actual plant.

Therefore, when the behavior of the actual machine is reproduced or predicted by a simulator, the external change conditions (input from the control panel, operation at the site, accident information, etc.) collected on the side of the actual machine are temporarily set to MT (magnetic field). It is necessary to store the data in a storage medium such as a tape device) and supply the external change condition to the computer off-line via the storage medium to simulate it.

The present invention has been made in view of the above circumstances,
Online connection between the actual plant and the plant simulator via bidirectional communication is possible via the hardwired mechanism, and various information sources of the actual plant are supplied online to the plant simulator via the hardwired mechanism, and the existing simulator mechanism is used. It is an object of the present invention to provide an actual plant operation support system in cooperation with the simulator, in which external change conditions are input to the simulator from the actual plant side by switching operation and the plant behavior can be simulated.

Further, according to the present invention, the future behavior can be predicted by high-speed calculation by the double speed setting, and the subsequent operation of the future behavior can be simulated by the control panel operation on the simulator side to enable the preceding training. The monitoring function in the actual plant control room enables online monitoring of simulated parameters, and not only actual observation data but also parameters such as void ratio that cannot be observed by the actual plant can be monitored. The purpose is to provide a support system.

[0009]

SUMMARY OF THE INVENTION The present invention provides interface means for fetching operation information from an actual plant control panel into a plant model computer of a simulator, and an actual plant control panel in place of an operation input signal from the simulator control panel. A system configuration including an operation input signal switching control means for receiving an operation input signal is provided. In addition, the actual plant control room will have a mansin interface with a simulator control function.

[0010]

[Function] Although the plant simulator is normally used for operation training, etc., by setting the "input mode from the actual plant" from the simulator control function of the actual plant control room, the control panel operation input, accident information , All other simulator control functions can be input from the actual plant control room.

In this state, all the operation information, accident information, etc. of the actual plant control board are input to the plant model computer of the simulator, the plant state is simulated, and the result can be monitored in the actual plant control room.

Further, if the simulator control function is set to a high-speed simulator mode (the simulation calculation is faster than the real time), the plant state can be predicted and can be immediately monitored in the actual plant control room. .

After simulating in the high speed mode, the simulator use mode is set, and the future state is operated by the simulator, so that the future training can be prepared in a state close to the actual machine.

As described above, by making it possible to take in plant information from an actual plant online without using the simulator itself, it is possible to perform plant behavior prediction, advanced training, detailed monitoring of physical parameters and the like. As a result, an advanced driving support function can be realized.
