Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the video monitoring equipment in the prior art cannot meet the simultaneous access of multiple clients, and whether the different video stream formats output by the video monitoring equipment produced by different manufacturers can cause the technical problem that the clients cannot be fully compatible. In order to provide a streaming media-based power grid monitoring system that can satisfy simultaneous access by multiple clients

Embodiment Construction

[0054] The structure of the grid monitoring system based on streaming media in the present invention is as follows: figure 1 shown, it includes:

[0055] A power grid monitoring system based on streaming media, including:

[0056] The client is connected to the central server through the network, including:

[0057] The request module sends a request for obtaining real-time video streams to the response module of the central server, and receives a response result;

[0058] The video management module receives the address of the sub-server where the real-time video stream is sent by the central server, and establishes a connection with the address to retrieve the real-time video stream;

[0059] The decoding module is connected with the video management module, and selects a corresponding decoder to decode according to the format of the real-time video stream; since the monitoring device is provided by different manufacturers, the format of the video stream collected is not t...

Abstract

The invention relates to a power grid monitoring system based on streaming media. The power grid monitoring system based on the streaming media comprises client sides, a central server, a plurality of sub-servers and a monitoring device. One client side sends a request for obtaining a real-time video stream to the central server. The central server searches for the sub-server where the real-time video stream is located, sends the address of the sub-server to the client side, and meanwhile sends a command for connection establishment to the sub-server. The sub-server packages the video stream obtained from the monitoring device and then sends the video stream to the client side. When other client sides simultaneously send the requests for obtaining the real-time video steam, the sub-servers forward the real-time video stream to the other client sides. According to the power grid monitoring system based on the streaming media, the technical problem that due to hardware limitation, the monitoring device can not meet the requests which are simultaneously sent by the multiple client sides and used for obtaining the video stream is solved.

Description

technical field [0001] The invention relates to the technical field of smart grids, in particular to a streaming media-based grid monitoring system and method. Background technique [0002] With the continuous expansion of the grid scale and the continuous improvement of substation automation technology, the unattended mode has been vigorously promoted in the grid. Power grid monitoring occupies a position that cannot be ignored in the process of power grid maintenance. There is an increasingly urgent need to use intelligent means to remotely monitor equipment remote operation, substation equipment operation status, and power environment monitoring. There are a large number of substations, which are widely distributed, and many of them are located in sparsely populated areas, which brings a lot of inconvenience to maintenance and management. [0003] Chinese patent document CN101964547A discloses a power grid monitoring system, including a station-end processing unit arrang...
