多标签多协议RFID读写器设计

Design of a multi-label and multi-protocol RFID reader

近年来,RFID(射频识别)技术发展迅速,应用日益广泛。本文设计了一种基于TRF7960的具有多协议自适应功能的RFID读写器,该读写器具有防碰撞、多标签识读功能,具备多种接口和图形化人机界面。本文从硬件和软件两方面阐述该读写器的设计。系统硬件结构包含CPU模块、读写器模块和接口。软件方面,描述了TRF7960驱动、读写器控制程序和多协议自适应的实现。最后,结合实际展望了该读写器的应用前景。

With the fast development and wide usage of RFID technology, the paper presents a design of a multi-protocol autoadaptive RFID reader based on the TRF7960.It supports anti-collision multi-label reading, and has various peripheral interfaces and graphical human-machine interface. The paper describes the design of the reader from two aspects： hardware and software. The hardware architecture is composed of CPU module, reader and interfaces. On software, the paper introduces the implementation of TRF7960 driver, reader control program and multi-protocol auto-adaptive function. Finally, the prospect of the reader＇s usage has been expected.
