Remote Meter Reading System By Power Line Carrier

With the worldwide low-voltage power networks, power line communication has an extensive practicability. Due to its mechanism intensity, security, and no need to re-invest, techniques of transmitting data via power line, developed in recent years, is used to automate the free collecting system in public service and the management of uptown service.With the development of economy, the consumption of electrical power has greatly increased. Because of the great amount and widespread of the power consumers, the workload of meter reading becomes burdensome. Remote Concentrated Meter Reading System is a good solution for this problem.This article discussed the advantage, disadvantage and the current state of the power line carrier communication. The advantage, method and current state of using spread spectrum technique in power line communication are discussed. Then the characteristic of low voltage power network was also compendious analyzed. In this paper, after introducing the principle of SSC, design of hardware and software of the system are been discussed. One important part of this system—the Power Line Carrier Meter is completed and every part of the unit is introduced. This system can provide many function such as call on meter, managing electric fee, power supply and stop supply, real time control etc. At last, the future of the power line communication is discussed.
