A remote energy metrology management system based on GPRS communication technology is presented to enable the energy management system to achieve accurate automated energy management. Taking the heat meter as a measurement in-strument,a three-layer framework is adopted to get the data from unit metrology meter through RS-485 bus interface by collec-tor. The collector is connected with the concentrator through wireless transmission module. The concentrator is connected with In-ternet by means of the GPRS function of the GPRS DTU module to upload the data to its server. The the hardware and software design of collector and the concentrator,key parts of the system,are studied in this paper. The experimental results show that the three-layer framework structure of energy metrology management system has the advantages of strong real-time performance and high accuracy,and is easy to extend.
