Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a prediction simulator that provides predictions of process state transitions, etc. to operators involved in process control.

[Conventional technology]

FIG. 3 is a block diagram showing a conventional prediction simulator disclosed in, for example, Japanese Patent Application Laid-Open No. 63-300278. 3 is a malfunction starting/terminating means, 4 is a malfunction data table for generating initial values and boundary values, and 5 is a simulation model for simulating the control panel 6. Next, the operation will be explained. First, when an operator gives a simulation run start command to the simulator 1 via the command console 2, the commanded simulation starts. - The malfunction data table 4 communicates with the control panel 6 as the simulation progresses, generates simulation initial values and boundary values related to process control, and provides them to the simulation model 5 to simulate the process simulation situation.

[Problem to be solved by the invention]

Since conventional prediction simulators are configured as described above, they do not simulate the process operations that operators are supposed to perform, so they have problems such as being unable to predict the process state including manual operations performed by the operators. was there. This invention was made to solve the above-mentioned problems. When an operator makes a prediction request, the process status is determined in real time based on the process data output from the prediction simulator section, and the corresponding operation is performed. The object of the present invention is to obtain a prediction simulator that can generate a procedure, import the operating procedure into the prediction simulator section, and continue the prediction simulation.

[Means to solve the problem]

In the prediction simulator according to the present invention, when an operator inputs a prediction request to the monitoring operation means via the monitoring control means when simulation is necessary, the initial value generation unit generates the initial value or the boundary value according to the request, and the boundary condition generation unit generates the boundary condition. The state monitoring section identifies the current process state in real time based on the intermediate results of the predictive simulation, and the operating procedure generation section sequentially generates and outputs operating procedures corresponding to the process state. The predictive simulation unit executes the operating procedure.

[For use]

In the predictive simulator according to the present invention, the condition monitoring section
The process state is identified from the intermediate results of the predictive simulation of the process data transferred from the predictive simulation unit, and the operating procedure generation unit generates the manual operating procedure that the operator should take from the process state, and the predictive simulation unit executes it. This allows operators to train while checking the operating procedures corresponding to the process status in real time.

【Example】

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 11 is a target process as a target real process, 12 is a process data collection system that takes in process data from the target process 11, 13 is a monitoring operation system as a monitoring control means, and a control panel 14
The process status is displayed on the display operation input device 15 for monitoring operation, and an input command for manual operation performed by the operator 22 is output to the target process 11. 16 is a prediction simulator system, and an initial value generation unit 17 that generates initial conditions for starting prediction of a process. A boundary condition generator 18 also generates boundary conditions, and a predictive simulation unit 21 models a process and executes it. It is comprised of a condition monitoring section 19 that receives predictive simulation data from the predictive simulation section 21 in real time and identifies the process state, and an operating procedure generating section 20 that generates manual operating procedures to be performed by an operator 22. Next, the operation will be explained with reference to the flowchart shown in FIG. First, when the operator 22 determines that prediction and simulation are necessary, the operator 22 performs the predictive varnish 1 via the monitoring operation display operation input device 15 that monitors the process state, and at the same time performs the initial value generation unit 17 and Boundary condition generator 1
Initial values and boundary values stored in 8 (abnormal event, size of anomaly, time of occurrence of anomaly, end of prediction simulation, etc.)
is input to the prediction simulation section 21 (step 5

-42), so upon receiving it, the prediction simulation section starts the simulation (step S"r43-
). The prediction simulation unit 21 of the prediction simulator system 16 outputs intermediate results to the state monitoring unit 19 based on predetermined time steps. The status monitoring unit 19 identifies the process status based on the intermediate results (step 5T45). The operation procedure generation unit 20 generates the operation procedure that the operator 22 should take next in accordance with the identification conditions (step 5T46). In the next step, it is determined whether the predictive simulation at this time step satisfies the termination condition (step S'l?47). If no, the operation procedure 22 is transferred to the predictive simulation unit 2.
1 is reissued (step ST48). If the prediction simulation results are satisfied, all prediction simulation results are output to the operation monitoring system 13 and the prediction simulation is ended (step 5T49).

【Effect of the invention】

As described above, according to the present invention, when an operator performs a predictive simulation of a process, he/she sends a prediction request from the supervisory control means and receives initial values, boundary values, etc. from the initial value generation section and the boundary condition generation section. The predictive simulation results are input to the predictive simulation section, and the intermediate results of the predictive simulation are taken into the condition monitoring section to identify the process status.Based on the results, the operation procedure generation section generates operating procedures and outputs the predictive simulation results to the operation monitoring system. As a result, highly accurate predictive simulation results can be obtained in real time.
This has the effect of instructing the operator on appropriate operating procedures.
