Next, the operation will be explained. The simulator computer (2) runs simulation programs and data that simulate the dynamic characteristics and control characteristics of the actual plant in accordance with the training process and training start conditions set from the instructor's desk (1). A simulated state corresponding to the operation from (3) is displayed on the display instrument on the training operation panel (3).

In the freeze state, the simulated plant state stops (freeze)
The command receiver is fixed in the state it was in at the time it was attached. That is, the feature is that the simulated plant time can be frozen.

The operation of the plant automatic control device (4) will be explained with reference to FIG. In Fig. 3, the functions being processed in the simulator computer (2) include the plant dynamic characteristics simulation model (21), the plant status signal transmitter model (22), and the auxiliary equipment control logic (23). model,(

and A/M7M stationary run) are the same as shown in FIG.

The automatic control device (4) of the plant has the same equipment configuration as that used in an actual plant, and input/output signals to the device are also performed via the same input/output processing section as in the actual device. This is used in the actual plant to investigate and adjust control elements such as cards and modules in the automatic control device (4) when conducting instrument maintenance training using the automatic side AV device (4). This is because it is necessary to be as close to the current state as possible.

The simulated plant state calculated by the plant dynamic characteristic model (21) is shaped by the signal transmitter model (22) to a signal level suitable for the automatic control device, and is input to the intransitive m device (4). In addition, a simulated plant auxiliary machine state signal is also input from the auxiliary machine control logic model (23). Depending on the control characteristics of the device, the automatic control device outputs control commands such as control valve operation commands to the control operating end model (24) that simulates control valve operation, and outputs control logic signals to the auxiliary equipment control logic model. do. The control operating end status (control valve opening, etc.) calculated using the control operating end model (24) is calculated by the automatic control device (4).
) and is input to the plant dynamic characteristic model (21). The auxiliary machine operating state signal changed by the control logic signal from the intransitive device (4) is also input to the plant dynamic characteristic model (21). A new plant state is calculated using a plant dynamic characteristic model (21) corresponding to these control states. The automatic/manual control status, control signal amount, and controlled amount of the automatic control device (4) can be monitored by the A/M station (5). In this way, Schroeter calculation I! +2
The simulated plant state calculated in 1 and the control elements in the automatic control device (4) constitute a feed/Ntsuk system.

FIG. 4 shows an example of the control functions performed by the automatic control device (4).

In the automatic control state, the plant state quantity signal (411) from the signal transmitter model (22) is sent to the deviation calculator (41).

In the manual control state, the operation signal of the A/M stage tumor is stored in the analog memory (45) as the manual control command signal (415).
), and is connected to the control command signal (416) in the manual control state using the automatic/manual signal switch (43).

In order to prevent a step change in the control command signal (416) when switching between automatic and manual, the integral value of the proportional integral calculator (42) and the memory value of the manual operation analog memory (45) are always equal. There is a tiger and king signal (417) from the computing unit in the control state to the computing unit in the standby state.

[Problem to be solved by the invention]

Conventional simulator equipment for operator training consists of plant dynamic characteristics that are processed by software calculations using a simulator computer, a control logic section, and an automatic control device similar to the actual plant, so that the automatic control device automatically If the simulated plant state is stopped (frozen) during control, the control operating end state calculated in the simulator computer and the signal oscillator output are fixed, so the control deviation in the automatic control device does not change regardless of the control command. However, since the automatic control device is not frozen, it continues to operate so that the control deviation is always zero, and the control command signal changes when the simulated plant state should be frozen. In addition, in order to completely fix the simulated plant state including the automatic control device, it is recommended that the automatic control device be switched to manual control mode at the same time as the stop (freeze) operation, and that no operations be performed from the A/M station. It was necessary to make it a condition. As a result, an HB occurred in which the control mode (automatic/manual) of the simulated plant state changed before and after the stop (freeze) operation.

This invention was made to solve the above-mentioned problems, and its purpose is to completely freeze a simulated plant state including an automatic control device by just a stop (freeze) operation.

[Means to solve the problem]

The operator training simulator device according to the present invention uses the set value of the automatic control device as an input to the automatic control device when the simulation training is temporarily stopped.

[Effect]

The operator training simulator device according to the present invention uses the set value of the automatic control device as an input to the automatic control device when the simulation training is temporarily stopped, so that the input of the automatic control device and the set value are the same, and the automatic control The device will stop automatic control.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIG.

In the figure, (22) is a signal transmitter model, (25) is a controlled signal switching model, (41) is a control deviation calculator,
(42) is a proportional integral calculator, (43) is a control signal switch, (44) is a setting signal analog memory, and (45) is a manual control signal analog memory.

When the emulator system is in operation, the operation is the same as that of the conventional system, and the simulated plant status signal (221) from the signal oscillator model (22) is selected by the controlled signal switching model (25) and sent to the automatic control device (4). is input to the control calculator (42). The subsequent operation is the same as that of the conventional system, so the explanation will be omitted.

In the stopped (freeze) state, the control set value signal (412) sent from the set value analog memory (44) of the automatic control device (4) to the system computer (21) is selected by the controlled signal switching model (25). Automatic control device (4
) is input to the deviation calculator (41). In this case, both of the two signals input to the deviation calculator (41) become set value signals, and the control deviation signal (413) becomes 0.

In this case, the proportional integral calculator (42) does not need to change the control command, so the current control command signal (416)
is kept constant.

〔Effect of the invention〕

As described above, according to the present invention, all simulated plant states can be frozen simply by the simulation stop (freeze) operation of the operator training simulator device. There is no need to manually change the control status of the i-device every time it is stopped. In addition, since the process of setting the control deviation to 0 is performed within the simulator computer, there is no need to modify each control element of the automatic control device, and even during instrument maintenance training, control elements (cards, cards, etc.) with the same specifications as the actual plant are used. modules, etc.), which has the effect of allowing training to be carried out without any discomfort.
