Cross-safety-subarea automatic electric-power control and monitoring system and method

Abstract

Provided is a cross-safety-subarea automatic electric-power control and monitoring system and method. The cross-safety-subarea automatic electric-power control and monitoring system comprises a safety area I monitoring server, a safety area I switch, a one-way forward isolation device special for electric power, a one-way reverse isolation device special for electric power, a safety area III monitoring server and a safety area III switch. A safety area III monitoring server is provided with a device configuration and control program, generates a query or control command file CMD. TXT to be stored in a folder CMD3 through the configuration and control program, the one-way reverse isolation device special for electric power timely scans the folder CMD3, converts a new file into an encrypted binary data flow and then transmits the encrypted binary data flow to the safety area I monitoring server when finding the appeared new file. The safety area I monitoring server reads the binary data flow transmitted from the one-way reverse isolation device special for electric power, performs decryption to form the file CMD. TX and stores the file CMD. TX in a folder CMD1.

Description

technical field [0001] The invention relates to an electric power automation control and monitoring system and method across safety partitions, and belongs to the technical field of automatic control and monitoring of electric power safe operation. Background technique [0002] According to their own information security requirements, power companies divide their business and equipment into four safe work areas: real-time control area (safety area 1), non-controlled production area (safety area 2), production management area (safety area 3 ), management information area (safety zone four). Logical isolation is allowed between the first security zone and the second security zone; the isolation level between the first and second security zones and the third and fourth security zones is physical isolation. [0003] In this way, the physical communication between the first safe area and the third safe area is physically isolated, which meets the requirements of the "National Po...

AI Technical Summary

Problems solved by technology

The main defect of this solution is that it only provides a data transmission method from the first safe area to the third safe area, but cannot transmit specific control data from the third safe area to the first safe area, and cannot achieve real pertinence Control and monitor the equipment and applications in the safe area
