The Design and Analysis of Remote Image Monitoring System for Electric Power Automation Based on CDMA

Abstract

With the development of codec technology and wireless broadband access system of the opening, use them as a hosted network, for low bit rate wireless video monitoring system is more and more get the attention of people. Based on CDMA network of the Internet are introduced in detail based on CDMA wireless communication for the working principle of the image monitoring and designed to CDMA mode of private network can be applied to power plant water station in remote areas, such as image monitoring scheme, involving network mode, the system monitoring module unit interior, related compression algorithm and background removal algorithm and should have the function of the system the background, proposed to improve the development direction of the wireless monitoring system. Along with the increasingly mature CDMA remote image monitoring system, remote monitoring of power system automation will inject fresh blood, to make contribution to the improvement of electric power automation. Introduction With the continuous development of electric power automation technology, make the power system automation level gradually improve, power plants, substations, stations and so on all need by monitoring system gradually achieve less people, no regulation, in order to improve production efficiency. Remote image monitoring is the telemetry, remote and remote control of further added. More and more remote image monitoring system of the electric power enterprises as a new means of power system automation management [1]. Remote power monitoring system was built in the center of the electric power dispatching management monitoring center, set up in each substation video, audio, data acquisition unit, or in power plants, substations, etc to set up the monitoring center on their equipment, video surveillance equipment and working environment [2]. Monitoring center of the data of each monitoring unit image monitoring and surveillance, can real-time, accurate, and directly understand and master the situation of the monitoring unit, and respond to what is happening in time, and can carry on the storage to the related data, analysis, provides forceful support for later decisions and to improve, to adapt to the needs of the modernization development. In this paper, which used in power system communication channel are analyzed and compared, combined with the rapid development of communication technology, put forward a kind of image monitoring system based on CDMA wireless channel. Based on the analysis of the characteristics of the CDMA structure and, fully affirmed the emerging transmission medium is applied to power system automation feasibility and broad application prospect, thus proves the system to improve the power system automation, improve the reliability and real-time performance is of great significance. CDMA network for electric power automation system provides a fast and reliable, easy extension, and easy to maintain communication mode, and the remote monitoring system based on the wireless communication, has no wiring work, reduce the network construction cost, save a lot of cost, short construction period, the expansion of sex is strong, high reliability, fast transfer rate, numerous advantages of rapidity, etc. As long as it is covered in CDMA network, image monitoring can at any time and do the real mobile monitoring.
