摘　　要：为了在设备点检中对设备识别,采用射频卡作为电子标识。设计了以SC32442处理器为核心,以EM4095为读卡芯片的射频识别系统;详细介绍了射频卡内芯片EM4100的曼彻斯特编码以及解码方法;编写了基于嵌入式Linux的读卡程序,该程序结合EM4100的编码特点,利用延时判断的方法进行解码,抗干扰性好。In order to identify the equipment in the spot-checking management,the RFIID card was used as the electronic identity card.Based on the SC32442 processor,a RFID system which took the EM4095 chip as hardware interface was designed.The Manchester encoding and decoding principles of the EM4100 chip was introduced.The decoding software based on embedded Linux was designed.The program used overtime checking to assure the reliability of decoding when it decoded each bit.This RFID system has been successfully applied in a spot lnspection instrument.
