[0002]

2. Description of the Related Art A plant simulator is composed of a simulator computer simulating a plant and a control panel as a monitor / operator for operating the simulator computer.

FIG. 5 shows a conventional plant simulator of this type.

In the figure, when a plant operation is executed from the monitor / manipulator 1, the contents of the operation are the simulator computer 2 connected to the monitor / manipulator 1 as an input signal a.
Is input to. The input signal a is processed by the process input / output processing means 3 of the simulator computer 2 with reference to the process input / output management table 4, and the processed process input data b changes the contents of the process input / output data table 5.

The process input / output data table 5 stores the operation of various interlocks of the plant, the actuator state such as valve opening, or the plant state quantity such as pressure and temperature and the plant manipulated quantity.

The plant simulation means 6 calculates the plant state by calculating the state value c of various processes from the process input / output data table 5, and outputs the calculation result d to the process input / output data table 5. The process input / output processing means 3 uses the process input / output data table 5
Process output data e is extracted and output to the monitor / manipulator 1 as an output signal f.

Now, the processing of the input signal a and the output signal f will be described with reference to FIG.

The input signal a has a type of a digital signal and an analog signal, respectively.
It is processed by the circuit as shown in.

As the monitor / manipulator 1, a monitor such as a manipulating switch / push button and a lamp 8 is provided as hardware like the manipulating switch 7 in FIG. 6, and the contact state i1 of the switch and the contact state of the switch i2 is input to the simulator computer 2 as a digital input signal a, the parts other than the operating device are simulated by the model 6, and the simulation calculation results of the switch contact state i3 and the switch contact state i4 are output as a digital output signal f. , The lamp 8 and other monitoring devices are turned on / off.

Taking an adjustment control system as an example in the analog system, the monitoring / manipulator 1 in FIG. 5 has a potentiometer 15 for setting a set value as shown in FIG.
Is provided as hardware, and an analog signal i5 representing the position amount of the potentiometer 15 is input as an analog input signal a.
As shown in FIG. 5, it is taken into the simulator computer 2 and the subsequent steps are simulated by the plant simulating means 6, and the analog signal i6 is output to the meter 16 etc. for display.

Next, the processing of the process input / output processing means 3 will be described. In FIG. 5, when the operation operation of the plant is executed from the monitor / operator 1, the operation content is the input signal a.

That is, the process input / output management table 4 includes the process input / output signal number uniquely assigned to the process input / output signal, the name of the monitor / operator connected to the process input / output signal number, or the point number indicating the position of the process input / output data table 5. The type of digital signal or analog signal is described. The point number is a series of numbers given for the reference and output data of the plant simulation means 6, and corresponds to the position of the process input / output data table 5.

As described above, the operated process input / output signal number is assigned to the input signal a.

[0017]

However, the conventional plant simulator described in FIG. 5 is composed of the monitor / manipulator 1 and the simulator computer 2, and the monitor / manipulator 1 simulating the control panel of the actual plant is completed. It takes a lot of time to carry out the operation, and therefore, there is a problem that the driving operation of the simulator cannot be performed early during the production of the actual plant.

That is, the monitor / manipulator 1 is a simulator of a control panel of an actual plant so that the operator can actually train the plant to obtain the same effect. The monitor / manipulator 1 is a simulator computer. Compared with No. 2, more time is required for production like the control panel of the actual plant.

For this reason, there are cases where it is not possible to sufficiently perform operational training with a simulator close to an actual machine before the operation of the actual plant is started, and the mission of the simulator has not been fulfilled sufficiently. Furthermore, the simulation of the plant simulated by the plant simulator was delayed, and the design change of the actual plant could not be made in time.

Therefore, an object of the present invention is to provide a plant simulator capable of operating training by a simulator by using means for simulating the control panel even before the control panel of the simulator is completed.

[0021]

According to the present invention, process input data based on operation information input by an operator is stored in a process input / output data table, and a plant simulation means executes a simulation calculation using the process input data. Then, the result of the simulation operation is stored in the process input / output data table as process output data, and in a plant simulator for operating and monitoring a simulated plant that notifies the operator of monitoring information based on the process output data to simulate the plant, When the first monitoring operation device simulating the control panel of the actual plant is connected, the first input signal based on the operation information is converted into the data format of the process input data to be the first process input data, and The corresponding first process output data in the process input / output data table Process input / output processing means for converting to an output signal and outputting to the first monitoring operation device, an input device for an operator to input a second input signal based on the operation information, and a second output signal based on the process output data. A second monitoring operation device simulating the first monitoring operation device, which comprises a display device for notifying the operator of the monitoring information by operation data, and operation data corresponding to the first input signal based on the second input signal. And input / output processing means for converting the display data into the second output signal corresponding to the first output signal, and the second process input by converting the operation data into a data format of the process input data. Process input / output simulating means for converting the second process output data corresponding to the process input / output data table into the display data, The second process input data is stored as the process input data in the process input / output data table, and the process output data is output as the second process output data to the process input / output simulation means. While connecting the simulation means and the process input / output data table, when the first monitoring operation device is connected, the first process input data is stored in the process input / output data table as the process input data, Providing process input / output data switching means for connecting the process input / output processing means and the process input / output data table so that the process output data is output to the process input / output processing means as the first process output data. It is the one.

[0022]

With the above structure, the second process input data is stored in the process input / output data table as the process input data, and the process output data is output to the process input / output simulating means as the second process output data. When the first monitoring operation device simulating an actual machine is connected, the process input / output data switching means stores the first process input data as process input data in the process input / output data table and the process output data as the first process output data. Is output to the process input / output processing means. Therefore, since the operation can be performed by the second monitoring operation device which is simple and can be manufactured at an early stage other than the control panel that simulates the actual device, the plant simulation can be performed by the plant simulating means at an early stage and before the completion of the actual device. It is possible to perform an operation confirmation test of a plant simulation means that simulates an actual machine. In this way, since the plant simulation operation can be performed in advance, it is possible to deal with the design change of the control panel of the plant simulator developed in parallel with the actual plant, and it is possible to improve the development efficiency. Then, when the first monitoring operation device as a control panel simulating the actual machine is completed, it is possible to immediately connect and perform the simulation.
