Problems solved by technology

[0002] In the current power system, the advantages of power line carrier communication technology are well known, it is a ready-made communication channel with the widest coverage, and an intelligent communication network can be formed with the least cost; but the high attenuation on the power line, The characteristics of high noise and large time variation are huge technical obstacles for low-voltage power line carrier communication technology; in addition, the application of low-voltage power line carrier technology is limited by carrier frequency, emission amplitude, harmonic pollution and other indicators, making the nodes in the system Therefore, the concept of relay is introduced in the low-voltage power line carrier communication technology; the use of relay enhances the anti-attenuation ability of nodes and improves the communication efficiency of the system, but at the same time makes the choice of relay a A new technical difficulty, that is, the technical difficulty of networking technology

Abstract

The invention discloses a power line carrier data communication system. Power line carrier data is split and encoded to solve the problems that strong interference and noise of a power line damage carrier communication data of the power line and further cause relatively low real-time communication rate and communication reliability. The system enables reliable work and higher anti-interference capability. Power interference of power carrier communication is eliminated, data transmission is accelerated, the system is suitable for long-distance carrier data transmission, the automatic degree ishigh, and the working performance is high.
