基于RFID的单相电子式预付费电能表的设计

Design of Single-phase Electronic Prepayment Watt-hour Meter Based on RFID

为了适应电能表高精度、低功耗、智能化的发展趋势,将射频识别技术应用到电子式预付费电能管理系统。介绍了系统的结构和工作流程,给出了主要电路模块的原理图,包括电能计量部分、射频接口部分等,并从低功耗和抗干扰等方面进行了可靠性设计。射频识别技术是未来电能表的一种重要的发展方向。

To adapt to the developing trend of Watt-hour meters in high accuracy,low power consumption and intelligence,the electronic prepayment energy management system is designed based on RFID.The structure of the system is introduced,and the schematic diagrams of the main ciscuits are given,including the sections of energy metrology and radio frequency interface,etc.The reliability of the system is also considered in the aspects of low-power consumption and anti-interfe-rence.The RFID technology is a kind of important direction of future Watt-hour meters.
