Unit), and the above-mentioned memory stores a transmission / reception processing program for performing control data transmission processing and status data reception processing, as well as operation training when an accident such as a fire described later occurs. A simulation program for performing a simulation is stored.

The transmission processing unit 6 has a state memory having a storage area for simulation and a storage area for normal operation.

In the normal mode, the transmission processing section 6 updates the data in both the simulation storage area and the normal operation storage area of the state memory each time the monitoring data is received from the slave station 2. Therefore, the latest monitoring data is always stored in both storage areas of the state memory. On the other hand, during the simulation mode, the transmission processing unit 6 updates only the data in the storage area for normal operation of the state memory each time the state data is received from the slave station 2 by executing the simulation program of the CPU. However, the state data received from the slave station 2 is not stored in the storage area for simulation.

In the simulation mode, the transmission processing unit 6 executes the simulation program of the CPU to generate simulated state data corresponding to the control data input from the supervisory control console 5 in the state memory simulation. The simulated state data is stored in a storage area for use in the monitoring control console 5.

The CPU executing the simulation program constitutes the simulation means described in the claims.

In the above configuration, first, the operation of the supervisory control device in the normal mode will be described below.

When the status data (display / measurement data) of the equipment 7 connected to the slave station 2 is input to the slave station 2 via the input / output unit, the slave station 2 sends the above status data to a predetermined state. After exchanging the data format, it is sent to the communication path 3.

The status data transmitted from the slave station 2 is
It is received by the transmission processing unit 6 of the master station 1 via the communication path 3. The transmission processing unit 6 performs sign verification of the received state data, and then writes this state data in both the storage areas for simulation and normal operation in the state memory. After that, the transmission processing unit 6 reads the state data stored in the storage area for simulation in the state memory, performs processing such as state change detection and scale conversion of measurement data, and then monitors the state data. Output to the control console 5.

The monitor / control console 5 displays the state of the equipment 7 on the display 4 based on the state data input from the transmission processing unit 6. If the above status data is accident data such as fire occurrence data, the monitoring control console 5

Next, in the above supervisory control device, a case where an operator who operates the supervisory control console 5 conducts operational training when an accident such as a fire occurs by simulation is shown in the flowchart of FIG. 2 together with FIG. It will be described below.

First, simulation start data is input from the system console console 8 to notify the master station 1 and the transmission processing section 6 of the start of simulation (S1). The monitoring control console 5 and the transmission processing unit 6 which have input the simulation start data from the system console console 8 change from the normal mode to the simulation mode.

During the simulation mode, the transmission processing unit 6 executes the simulation program, and every time the transmission processing unit 6 receives the state data from the slave station 2, the storage area for normal operation of the state memory is stored. Only the data is updated, and the latest state data is always stored in the storage area for normal operation.

Next, if, for example, a simulated fire outbreak is set from the system console table 8 (S2), the data in the storage area for simulation of the state memory in the transmission processing unit 6 is rewritten with the fire outbreak data. After that, the transmission processing unit 6 reads the fire occurrence data stored in the storage area for simulation in the state memory, and outputs this data to the monitoring control console 5 (S3).

The supervisory control console 5 to which the fire occurrence data has been input from the transmission processing unit 6 displays an accident on the display 4 and activates the alarm 9 connected to the supervisory control console 5 (S4). ).

That is, the operator operates the keyboard 3 of the monitor control console 5 to input control data for operating disaster prevention equipment (equipment equipment 7) such as a pump and a water sprayer (S5). Here, the supervisory control console 5 sets a simulation flag for the control data input during the simulation mode. That is, the supervisory control console 5 adds a simulation flag to the input control data and outputs it to the transmission processing unit 6.

(Data) is written in the simulation storage area of the state memory, and this simulated state data is returned to the monitor control console 5 (S6).
Upon receiving the simulated state data from the transmission processing unit 6, the supervisory control console 5 displays the control response of the disaster prevention equipment on the display 4 according to the simulated state data. The operator confirms the display on the display 4 and further operates the monitor control console 5 as necessary.

Only the data is written and the storage area for normal operation is sequentially updated.At this time, when accident data such as fire occurrence data is received as status data, the normal mode is immediately entered and normal operation is performed on the storage area for simulation. The state data (accident data) stored in the storage area for use is copied and output to the monitor control console 5. Simultaneously with this, the simulation end data is transmitted to the supervisory control console 5,
