Power distribution surveillance video data transmission system based on metropolitan area network distributed architecture and control method

Abstract

The invention discloses a power distribution surveillance video data transmission system based on a metropolitan area network distributed architecture. The power distribution surveillance video data transmission system comprises a photographic device in a power distribution room in a community, a converging device used for converging multiple paths of power distribution video surveillance signals, and a power distribution video surveillance platform. The photographic device sends the multiple paths of power distribution video surveillance signals to the converging device for backup. The converging device is connected and communicated with the power distribution video surveillance platform through an electric power gateway with a firewall function and a metropolitan area network special for electric power. The power distribution video surveillance platform actively issues a flow guiding demand instruction to the converging device in the community, and the converging device in the community responds and then uploads power distribution video surveillance signal data which is collected through the photographic device in the power distribution room according to the instruction. The invention also discloses a power distribution surveillance video data transmission control method based on the metropolitan area network distributed architecture at the same time. According to the power distribution surveillance video data transmission system and the power distribution surveillance video data transmission control method based on the metropolitan area network distributed architecture, necessary hardware investment cost is reduced, existing network conditions and resources are fully utilized, network loads and long-time bandwidth occupation are reduced, and ordered management of a city-level power distribution equipment surveillance system is realized.

Description

technical field [0001] The invention relates to a monitoring video data transmission system and a control method thereof, in particular to a power distribution monitoring video data transmission system based on a distributed architecture of a metropolitan area network and a control method thereof. Background technique [0002] Existing electrical equipment is equipped with monitoring. The current digital video surveillance technology has become more and more mature and popular. The development of digital video surveillance signals, video compression, and remote transmission technology has made the disadvantages of the original set of video surveillance solutions for power distribution equipment more and more obvious. The monitoring of power equipment is not limited to the short-distance realization in a local area, but can also be extended to the entire city, using the power exclusive metropolitan area network to realize remote video monitoring on key nodes of the network (s...

Problems solved by technology

[0003] Although the video has been compressed, considering that the monitoring signals of such a large number of power distribution monitoring points in the whole city are sent to the power supply bureau in the future, it will inevitably cause a serious network burden on the power exclusive metropolitan area network, and even cause network congestion in severe cases and traffic jams, and even affect the normal use of other businesses

It will also increase the operation and maintenance cost of the entire city-level monitoring system, increase hardware investment costs, make it impossible to use existing network conditions and resources, increase network load and long-term bandwidth occupation, and reduce super-large concurrent random access and flow control processing capabilities
