Abstract:By studying the wireless meter reading system and taking advantages of the bluetooth short-distance communication，this study presented a wireless meter reading system based on bluetooth technology and Advanced RISC Machines(ARM). After analyzing the needs of the wireless meter reading，the overall structure of the system was put forward. Taking CSR's bluetooth chip as the core，bluetooth communication devices were designed. In order to improve the performance of the overall system，ARM processor was adopted as the primary processor in the core components concentrated center of the system. In order to achieve remote data transmission，GPRS modules were used. Through the research focused on the work process，as well as the bluetooth device piconet communications，software design and software flow chart were given. Application results show that the design is efficient，reliable, and provided with good performance，which can offset the deficiencies in existing programs.
