摘要
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.
