Power Measurement and Application of Remote Meter Reading

Traditional manual meter reading, pre-paid system and remote meter reading system are three forms of current power sale management system. This paper analyzes their advantages and disadvantages and their development. The structure and characteristics of remote meter reading system are introduced, from the aspects of the power measurement device, collector, concentrator, data center and communication mode the development and application of remote meter reading technology are described. Characteristics of traditional mechanical power meter, pulse power meter, infrared based power meter and 485 based power meter and the corresponding collector of data collection are presented. The DL/T645 power meter communication protocol, Power Line Carrier remote meter reading system and GPRS/CDMA network remote meter reading system are studied emphatically. The data center building and patterns of cooperation with banks are discussed. The development direction of the remote meter reading system is indicated.
