摘要
在对射频识别(RFID)系统的组成和原理进行分析的基础上,提出基于Philips公司MFRC500型读卡器和AT89S51型单片机实现的射频识别读写器的设计方法。首先介绍RFID系统的组成及MFRC500的特性,接着给出由AT89S51型单片机和MFRC500构建无源RFID系统的原理设计,以及对MifareS50卡的读写流程。
The composition and principle of the RFID system are described, and a RFID reader based on Philips MF RC500 and AT89S51 MCU is presented. Firstly, the RFID system＇s composition and MF RC500 features are introduced, then the system design of passive RFID based on AT89S51 and MF RC500 is presented. Finally, the read-write flow of Mifare S50 card is given.
