Quanzhou Electric Power Bureau Of Network Monitoring System Design And Implementation

As an important part of power system.the safe operation of substation directly influences that of the whole power system. With the development of automation level and unmanned degree of the main part of substation.the high requirement in technology as to auxiliary equipment has become more and more intensive.This paper first introduces the structure of the substation supervision system, its main function and development situation.Then it introduces the data traffic of the substation supervision system,emphasizing the important role of the communication in the system.On the basis of this,it introduces the building of communication monitoring system and functions of network management.The frame work of the system is given, and the implementation flow of the streaming media server is described from the software.The results and analyses of the experiment are given as follow.The entire design proposal proved to be reliable which passed through the test analysis.Video surveillance is always an applied technology which people pay a lot of attention to with its clarity,convenience and abundantin for mation.Digital video surveillance system is an integration of advanced technology,including computer, multimedia and network communication.It not only accords with the development trend of information technology, but represents the development direction of monitoring industry.It is widely used in all walks of life,which has improved the efficiency of management and automated level tremendously.Aiming at the present requirements for unattended power station and remote monitoring,the paper describes the remote video surveillance system design and implementation of the system.The module design and function technology including video compression,decompression,video data transmission and otherwise have been conducted to achieve a more detailed introduction. Firstly,it introduces the constitution of the substation video surveillance system, including substation site,computer network data transmission,and client monitoring center.Using hardware compression card (capture card) to capture the scene of the monitoring scene in the video capture port,developing the application programming interface monitoring system by using object-oriented protocol connections (TCP), and finally the receiving distance decodes and decides to play or save after receiving the video stream.A kind of intelligent alarm system for transformer substation area is introduced. It includes the functions of theft-proof and fireproof, performing automatic detection .Pyroelectric infrared sensor and magnetic switch combined are used for theft-proof so as to realize automatic detection. Temperature sensor and hydronium smoke sensor are integrated to a compound detector for fireproof. Multi-sensors make the least false alarm and enhance the reliability of system.
