RFID Meter Reading System Based on CAN Bus and ARM Technology
基于CAN总线和ARM技术的集中电表抄表系统

At present, the RS485 meter reading system, or the IC electricity selling system is mainly used in domestic meter reading systems. But, technical defects exist in both of the above systems. This paper presents the RFID meter system using CAN bus and ARM technology. This system cannot only avoid the shortcomings of the RS485 and the IC system, but also has the advantages of both. The user can either buy electricity directly or use rechargeable card to buy electricity. In the meantime, the management and electricity sectors can implement real-time monitoring and managing of the user's electricity utilization.
