Embodiment 1

[0028] figure 2 A schematic structural diagram of the improved DCS computer system provided by the first embodiment of the present invention is shown, and the details are as follows:

[0029] The improved DCS computer system described in the embodiment of the present invention includes:

[0030] A server for providing data sources, a switch connected to the server, and a computer connected to the switch through a network. A disk array is connected to the computer, and the computer adopts virtualization technology to set the disk array to include several virtual hosts.

[0031] Specifically, the server used to provide the data source includes a simulation server of the power plant control system. The simulation server of the power plant control system is connected to the simulation server of the power plant equipment or connected to the power plant equipment. When connected to the simulation server of the power plant equipment, it can simulate the The data of the power plant ...

Embodiment 2

[0042] Figure 4 It is a flow chart of the realization of the improved DCS computer system compatibility method provided by the second embodiment of the present invention. The improved DCS computer system in this embodiment includes a server, a switch connected to the server, and a computer connected to the switch through a network. There is a disk array connected to it, and the compatibility method is detailed as follows:

[0043] In step S401, several virtual hosts are configured in the computer.

[0044] Specifically, the number of several virtual hosts is configured in the computer to match the number of man-machine control systems that need to be set, and of course more virtual hosts can also be set. In the configuration process, configure several logical partitions in the disk array, and configure the virtual host in the logical partition. The method of configuring the virtual host can be installed on the basis of the operating system carried by the memory of the comput...

Embodiment 3

[0052] Figure 5 It is another implementation flow chart of the improved DCS computer system compatibility method provided by the third embodiment of the present invention, which is described in detail as follows:

[0053] In step S501, the disk array is configured into several logical partitions.

[0054] Specifically, the number of logical partitions required is determined according to the number of virtual hosts that need to be configured, and the size of the logical partitions can also be flexibly configured according to the space required by each man-machine control system, such as the data that needs to be recorded in the historical server If there are more, you can configure a larger capacity accordingly, and for real-time servers, etc., you can allocate a smaller storage space.

[0055] In step S502, several virtual hosts are configured in the computer.

[0056] In the logical partition mentioned above, set the virtual host. Considering storage space saving and util...

Abstract

The invention belongs to the field of nuclear power station digital control systems, and provides an improved DCS computer system, a compatible method and a compatible device. The system comprises a server used to provide data sources, a switch connected with the server, and a computer connected with the switch through a network. The computer is connected with a disk array. A virtualization technology is used in the computer to set the disk array as a logic hard disk including a plurality of virtual hosts. Through arranging the plurality of virtual hosts in the disk array, problems in the prior art that since a plurality of computer hardware is needed to form a DCS computer system, maintenance cost is high, and that production of original devices are stopped and purchasing is not easy are solved, thereby simplifying network structure of the improved DCS computer system, being convenient to maintain, and greatly reducing purchasing cost of hardware equipment.

Description

technical field [0001] The invention belongs to the field of nuclear power plant digital control systems, and in particular relates to a computer system, a compatible method and a compatible device for an improved digital control system (English full name is digital control system, English abbreviation is DCS) for nuclear power plants. Background technique [0002] The OM690 system used in nuclear power plants is a man-machine control system used in power control. It is a logic analysis program used to apply human operation instructions to the controlled equipment and intuitively display the data of the controlled equipment. At present, nuclear power plants generally install the OM690 system in the DCS computer system, and run the installed OM690 system through the DCS computer system. [0003] see figure 1 , is a structural diagram of the DCS computer system currently used in nuclear power plants. The DCS computer system includes 14 operation station terminal servers (Ope...
