Design of Intelligent and Remote Meter Reading System Based on GPRS and Low-voltage Power Line Carrier Communicatio

The paper proposed a design scheme of intelligent and remote meter reading system based on GPRS and low-voltage power line carrier communication,gave general structure of the system and expounded implementation of the GPRS communication and PLC communication.It introduced design of the concentrator and the collector of the remote terminal in details and gave meter reading steps of the master.The intelligent and remote meter reading system uses lower-voltage power line as transmission channel of the concentrator and the collector,and uploads the energy data stored by the concentrator to the master by GPRS wireless data communication technology,which realizes the function of remote and automatic meter reading of the electric quantity.The actual application showed that the system can reduce working strength greatly and improve automatic degree of energy management.
