Communication control method for provincial master station and regional master station

Abstract

The invention discloses a communication control method for a provincial master station and a regional master station. The regional master station is used for monitoring monitoring information of a plurality of sets of substation primary equipment in real time, and uploading the information to the provincial master station; the provincial master station is used for monitoring monitoring information of a plurality of regional master stations in real time; and in a communication network of the provincial master station and the regional master station, a session initiation protocol (SIP) is used as the communication protocol to meet expandability application requirements of session parameter negotiation, monitoring parameter adjustment, common management and control of front-end monitoring equipment and openness between the two master stations. As the SIP is used in the network transmission between the provincial master station and the regional master station, the two master stations have openness and expandability, and can conveniently provide large-scale video monitoring services.

Description

technical field [0001] The invention relates to a communication control method for a provincial-level master station and a regional-level master station, and belongs to the field of power grid security communication. Background technique [0002] With the continuous expansion of the grid scale, the workload of grid monitoring and operation and maintenance is increasing, and the technology of remote real-time monitoring and remote operation of primary equipment in substations is also becoming more and more popular. For example, Guangdong Power Grid took the lead in adopting a three-level video surveillance system at the provincial level, regional level and station end in the power industry: the provincial master station (full name substation video and environmental monitoring provincial master station system) is used to monitor multiple regional master stations real-time monitoring information; the regional master station (full name substation video and environmental monitori...

Problems solved by technology

However, due to the lack of industry standards and low market access requirements, some equipment manufacturers blindly produce all kinds of video surveillance equipment in pursuit of commercial interests, resulting in the reliability, stability, openness, and reliability of some remote video surveillance systems currently in the application stage. Scalability and security and confidentiality performance are relatively poor, causing great inconvenience and loss to users, and unable to meet the requirements of manageability and operability
