Substation video monitoring system based on SIP protocol and video transmission method

Abstract

The invention discloses a substation video monitoring system based on an SIP protocol. A plurality of camera groups are respectively connected with a lower video server which is connected with a lower PC machine. The lower video server is connected with an upper video server through an SIP protocol gateway. The upper video server is respectively connected with an alarm device and an upper PC machine. The invention also discloses a video transmission method which comprises the following steps: a lower platform registers to an upper platform; the lower platform sends a NOTIFY message to the lower platform and informs an event to the upper platform; the lower platform pushes monitoring region information and monitoring scene information in an XML message body orderly to the upper platform; camera information is pushed; and the upper platform sends '200' to the lower platform, which indicates that the pushing of the information is completed. According to the system and the method, the video monitoring information collected by a camera is subjected to grading management and the real-time information transmission is realized through the SIP gateway between an upper level and a lower level, and the purpose of sharing information is achieved.

Description

technical field [0001] The invention relates to a substation video monitoring system and a video transmission method, in particular to a substation video monitoring system and a video transmission method based on the SIP protocol for hierarchical management and information sharing between upper and lower levels. [0002] Background technique [0003] The substation video surveillance system in the existing power system is constructed by different departments in different periods and with different projects, and the systems and equipment of different equipment manufacturers and different periods are used, forming the current product models with many types and technical performance indicators. Uneven, unable to unify the status quo of centralized monitoring. Not only can it not meet the requirements of unattended substations, but also can not meet the development needs of the intelligent construction of the power grid, which seriously affects the intelligent improvement of t...

[0003] The substation video monitoring system in the existing power system is constructed by different departments in different periods and with different projects, and the systems and equipment of different equipment manufacturers and different periods are used, forming the current product models with many types and technical performance indicators The status quo is uneven and cannot be unified and centralized monitoring

It not only fails to meet the requirements of unattended substations, but also fails to meet the development needs of the intelligent construction of the power grid, which seriously affects the intelligent improvement of the video surveillance system, and cannot effectively utilize the technology of the video surveillance system in the lean management and intensive management of the company support

Therefore, unified construction standards, unified technical system and unified platform management to meet the global and integrated development needs of video surveillance systems have become the key technology to solve the interconnection of video surveillance systems from various manufacturers. At present, there are no literature reports and Applications
