[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant monitoring system for a nuclear power plant or the like, and more particularly to a plant monitoring system suitable for monitoring plant operation information, alarm information, plant control, and the like.

[0002]

2. Description of the Related Art In a large-scale plant such as a nuclear power plant, in order to manage a wide variety of equipment, each equipment is managed by being classified into units called a system classified according to its function and purpose. A device monitoring and operating device for monitoring and operating a device is generally provided for each system.

FIG. 7 shows an example of the above-described plant monitoring system.

The illustrated plant monitoring system includes a plant monitoring device 100 and a plant device 101, and the plant monitoring device 100 for connecting the plant device 101.
Is roughly divided into a system by connecting a plant equipment control device 1 and a plurality of device monitoring and operating devices 2-n provided for each system and a plant computer 3 via a network 4. A display device 5 as a man-machine device and an input device 6 are connected, and a display device 7 as a man-machine device and an input device 8 are connected to the plant computer 3. The network 4 has a plurality of connectors 4a to 4e such as connectors, and is connected to each device.

[0005] First, the process information a taken from the plant equipment 101 is subjected to predetermined processing by the plant equipment control device 1 to become process information that can be transmitted to a higher order.

Next, the process data processed by the plant equipment control device 1 is transmitted via the network 4. In the plurality of device monitoring and operating devices 2-n that have received the process data in units of systems, monitoring operation information is generated by the corresponding device monitoring and operating device 2-n, and the monitoring screen and the operation screen of the display device 5 are displayed. On the other hand, an operation command is transmitted to the network 4 in response to a request from the input device 6.

On the other hand, the plant computer 3 fetches process data of the entire plant via the network 4 and
A predetermined process is performed to display monitoring information of the entire plant on the display device 7
And a required request is input from the input device 8.

As described above, the process information input from the plant equipment 101 to the plant monitoring device 100 is transmitted to the device monitoring and operating device 2-n via the network 4. The plurality of device monitoring and operating devices 2-n that have received the process information display the process information on the display device 5, and the operation command information received from the input device 6 is processed and transmitted to the plant device control device 1 via the network 4. To send device operation command information.

[0009] Upon receiving this, the plant equipment control device 1 performs an operation on the plant equipment 101. As described above, it is possible to divide the production of the device monitoring and operating device 2-n into the system units. In addition, since it is possible to place an order separately for each system, the production process is adjusted at the optimal time for each system,
Production and testing are performed for each system, and the resources for production can be used effectively.

On the other hand, for the operation of the plant, it is necessary to perform monitoring based on the overall information processed by combining the process information input from each system. For this reason, in the device monitoring and operating devices 2-n classified in each system unit,
It is necessary to exchange information between the device monitoring and operation devices that provide information between the respective systems. However, when such information is individually exchanged for each system, hardware such as a PI / O device to be exchanged increases. For this purpose, a plant computer 3 is usually provided separately, process information from the plant equipment control device 1 is input, a plurality of pieces of process information are combined, and calculation processing of monitoring data of the entire plant is performed.
The monitor screen is displayed and the management form is output. The operator performs the operation of the plant based on the entire plant information provided from the plant computer 3 and the information of the system unit provided from the device monitoring and operating device 2-n and the device operation function.

[0011]

By the way, in the plant monitoring system shown in FIG. 7, the equipment monitoring and operating device 2-n, the display device 5, and the input device 6 are provided for each system, and information on the entire plant is provided. Since the display device 7 for monitoring is required exclusively, there is a problem that the number of display devices for plant operation increases.

In addition, since the information of the entire plant by the plant computer 3 and the information of the system unit by the device monitoring and operating device 2-n are displayed on separate display devices, the two display devices are monitored during the plant operation. It is necessary to drive while driving, which may be a burden on the operator. Although it is possible to provide the plant computer 3 with a system level display function equivalent to that of the device monitoring and operating device 2-n, in this case, the same screen is separately manufactured for the device monitoring and operating device and for the plant computer. Required, and the production and test operations are doubled, which increases costs.

In order to solve this problem, a plant monitoring apparatus is conceivable in which plant-level information and system-level information are displayed on the same display device so that equipment can be operated.

However, in order to realize such a plant monitoring system, plant level information is transmitted to a device monitoring and operating device using a network from a conventional plant device control device, and the plant level information is displayed on a display device. If this is attempted, the following problems will arise.

First, since the networks of each system perform high-speed data transmission for equipment control, if a large amount of plant-level information flows on the same network, the equipment operation command data A delay occurs, which slows down the response of device operation.

Second, information provision via a network cannot be applied to a system that requires high-speed controllability to control a plant equipment control device.

Third, when the equipment monitoring and operating devices of each system have only transmission means completely different from the plant computer, information on the entire plant level cannot be provided and displayed on the equipment monitoring and operating devices. .

Fourthly, in the above-described third case, the switching at the physical signal level such as the electrical or optical signal is performed, and when realized, the screen at the plant level is automatically switched. Can not.

Fifth, although the equipment monitoring and operating devices of each system have transmission means common to the plant computer, they cannot be realized only by providing process information when they have only completely different software environments.

Sixth, although the plant computer has a common transmission means and a common software environment in the equipment monitoring and operating device of each system, it cannot be realized unless means for sharing screen display information is provided.

Accordingly, the present invention provides a plant monitoring system which eliminates the man-machine device provided in a conventional high-order plant computer or the like, realizes consistent operation by unifying the man-machine device, and simplifies the system. The purpose is to provide.
