摘要
传统的低频RFID阅读器,不仅识别距离短,也不具有野外环境下的工作能力,根据实际应用需求,设计并实现一种应用在生态环境监测系统的低频RFID阅读器的发射电路,符合国际标准ISO11784/11785中的半双工(HDX)系统的要求,给出整体阅读器发射电路硬件的工作原理、模块组成和电路设计,经测试,阅读器具有功耗低、识别距离远、抗干扰能力强等特点.
The traditional LF RFID reader not only has a short recognition distance,but also does not have the ability to work in the field environment.According to the actual application requirements,designed and implemented a LF RFID reader transmitter circuit used in an ecological en⁃vironment monitoring system,which is in line with international the requirements of the half-duplex(HDX)system in the standard ISO11784/11785,the article gives the working principle,module composition and circuit design of the overall reader transmitting circuit hardware.After testing,the reader has the characteristics of low power consumption,long recognition distance,and strong anti-interference ability.
