| Abstract: | Data transmission and information exchange in the network are key problems of the wireless meter reading system. This paper presents an automatic meter reading system which includes a centralized reding terminal based on the RS485 bus and runs on the GPRS/GSM public network platform. The security, reliability and maintainability problems of the data transmission and information exchange are also discussed. |
