Safety communication method and system for power grid monitoring system

Abstract

The invention discloses a safety communication method and a safety communication system for a power grid monitoring system. The system comprises a power grid monitoring system backbone network, wherein a master server for processing monitoring information is connected to the backbone network, and is connected with a slave server through a serial heartbeat detection line; the master server operates a heartbeat program to periodically transmit a heartbeat signal to the slave server and receives the heartbeat signal from the server and analyzes the heartbeat signal; and when the master server is failed, and an overtime heartbeat signal is analyzed by the slave server or the heartbeat signal cannot be received by the slave server, the slave server replaces the master server to serve as a novel master server to process the monitoring information of the power grid monitoring system. When the master server of the power grid monitoring system is failed, the slave server replaces the master server to serve as the novel master server to process the monitoring information of the power grid monitoring system, the problem that the power grid monitoring system is paralyzed due to failure of the master server is solved, and the safe operation of the power grid is guaranteed.

Description

technical field [0001] The invention relates to a safe communication method and system of a power grid monitoring system, and belongs to the field of power grid security communication. Background technique [0002] With the continuous expansion and development of the power industry, the image monitoring technology applied to the power grid, especially the remote image monitoring technology, has developed rapidly. Therefore, in the case of a single monitoring terminal simultaneously monitoring multiple monitoring front-ends in real time, or multiple monitoring terminals simultaneously monitoring a single monitoring front-end in real time, as the hub core of the monitoring system - the server is prone to downtime and suspended animation and other failures, and it takes a certain period of maintenance to resume work. During this interval, there will be a vacuum in monitoring and supervision and loss of monitoring information. irreparable loss. Moreover, after the monitoring s...
