RFID在电能计量系统中的应用

在市场经济下，人们对电能的计量要求准确度越来越高，而对用电的管理要求实现智能化、自动化。而RFID作为一种非接触式的自动识别技术，它通过射频信号自动识别目标对象并获取相关数据，识别工作无须人工干预，将RFID应用到电能计量系统，通过信息载体-射频卡，实现信息的双向传递，电能表用户与预付费管理系统之间通过射频卡建立联系。文中提出了一种应用RFID的电能表的计量与管理方案，并且介绍了电能表对射频卡进行读写操作的硬件及软件设计，这种预付费电能表充分发挥了射频卡无需电源供给、非接触、大容量、高安全性的优点。

RFID in the energy metering system

In the market economy, people's power measurement accuracy requirements of more and more on the management of the electricity demands of intelligent automation. The RFID as a non-contact automatic identification technology, through its radio frequency signal automatic target recognition and access to relevant data, no need for human intervention identification, RFID will be applied to the energy metering system, through the information carriers -radio frequency card, the information Two-way transmission of electric energy meter prepaid users and management systems through radio frequency networking card. This article does a RFID application of the energy meter measurement and management of the program, and introduced the energy meter reading and writing for radio-frequency card operate the hardware and software design, this prepaid energy meter and give full play to a radio frequency card without power supply Non-contact, high-capacity, high security advantages.
