DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant monitoring control system for displaying and monitoring and controlling plant information such as a power system on a CRT or the like, and a storage medium storing a processing program of the system.

[0002]

2. Description of the Related Art For example, a monitoring control server in a power system monitoring and control system has a monitoring function of outputting information received from a power system to a system monitoring panel and an operator console, and a control function of outputting control information from the operator console. Has a function. The control of the power system is performed from the operator console via the monitoring control server.

In the operation of a power system monitoring and control system having a plurality of operator consoles, a supervisor manages and supervises the control status by telephone or direct instructions to an operator.

FIG. 18 is a configuration diagram showing an example of the above-described power system monitoring and control system.

In FIG. 1, an operator console (1) 200A of a central monitoring operation room 21 receives and outputs monitoring control information via a power system 1 and a network 20. The client computer 2 and the CRT 6 connected to the monitoring control server 100 via the network 22 are installed. The operator console (2) 200B is provided with the client computer 3 and the CRT 7 connected to the network 22 and the operator console (3). ) 200C is provided with a client computer 4 and a CRT 8 connected to the network 22. Further, the supervisor table 300 includes the network 2
2, a client computer 5 and a CRT 9 are installed.

[0006] The operator operates the CR of each operator console.
The information on the power system 1 is monitored on T6 to T8, and the operation is performed as necessary. On the other hand, the supervisor monitors the display information on the CRT 9 and gives advice to the operator.

[0007]

However, FIG.
Supervisory table 30 of the power system monitoring and control system as shown in FIG.
0 CRT 9 is displayed on the operator console 200A,
The information is created separately and independently from the display information of the CRTs 6, 7 and 8 of the 200B and 200C. The supervisor cannot see the display information of the CRTs 6, 7, and 8 representing the operation status of the operator, and the supervisor does not The operation status could not be monitored directly from the supervisor desk. For this reason, the operation status and instruction contents of the operator are transferred to the telephone or the operator desk, and are performed, which hinders quick and accurate advice.

Therefore, the present invention enables a supervisor to manage the operation status of an operator at a supervisor's desk, and also allows a supervisor to call an operator operation screen of another facility via a network, thereby providing more information.
