基于CAN总线和ARM技术的集中电表抄表系统

RFID Meter Reading System Based on CAN Bus and ARM Technology

目前国内抄表系统大多数采用的是RS485抄表系统,或者IC售电系统,但这两种系统都存在一些技术上的缺陷。提出了采用CAN总线和ARM技术的RFID抄表系统,该系统既避免了RS485系统和IC售电系统的缺点,又兼有两者的优点,用户既可以直接购电,也可以用充值卡购电,同时管理部门和供电部门又可以实时监控和管理用户的用电。

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.
