基于ARM7的RFID读写器硬件系统设计

摘要

介绍一种通用的基于ARM7的13.56MHZ RFID读写器硬件系统设计过程.该系统通过LPC2364(ARM7)对MFRC500射频识别芯片进行驱动和控制,利用DM161A芯片与PC机进行网络通信和传输实时数据.经实践证明该系统可以读写Mifare One等射频卡,在实际情况中底层的软件和硬件不需要修改,无需了解底层的细节,方便与上位机的连接与通信,有利于进行二次开发,具有一定的通用性.该方案具有广阔的应用前景.%Introduced a universal 13.56MHz RFID reader hardware system based on ARM7 designing procession.The system uses LPC2364(ARM7)to drive and control the MFRC500 RFID IC chip and the DM9161A IC chip to communicate with the PC by the network and transfer real time data. The result of experiment shows that the system can read-write the Mifare One RFID card, facilitates the connection between PC and communications. No need to modify the firmware and hardware and just change the PC software development is conducive to the second development and has a certain universal. This design scheme has wide application future.
