| Abstract: | 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 appl... |
