摘要
射频识别技术(RFID)是一项利用射频信号通过空间耦合(交变磁场或电磁场)实现无线方式对电子数据栽体进行识别的新兴自动识别技术。针对低功耗和高效性,设计了一种以Nuvoton Nano110低功耗MCU为核心的125KHz的RFID控制阀系统。该系统采用分立元件搭建了成本极低的ATA5567射频卡读写电路,构建了段码式LCD显示和控制阀门的电机驱动模块。通过实践检验了系统的稳定性,可将其用于成本敏感的预付费卡表(水表、燃气表和热量表等)。
Radio frequency identification （RFID） is a new automatic identification technology which uses radio frequency signal through space coupling （alternating magnetic field or electromagnetic field） to achieve electronic data carrier in wireless way.For low power consumption and high efficiency,a Nuvoton Nano110 low power MCU based 125KHz RFID control valve system is introduced.The system uses discrete components to build the ATA5567 RF low cost card read-write circuit,constructs the motor driver module of segment code LCD display and control valves.The stability of the system is tested by practice,and it can be used in prepaid card tables cost sensitive （water meter,gas meter and heat meter etc.）.
