摘要
设计了基于ISO18000-6C标准的USB2.0数据通信协议便携式射频读写器。以Altera EP1C3T144为核心控制器、CC1100为RF收发器、CH372为USB接口器件,组成了该硬件系统。经测试,系统收发频率为889MHz,最高数据传输速率为240kbps,天线发射功率为1.1dBm,读写器稳定传输距离为1m,数据传输准确,系统读写稳定可靠,抗干扰能力强,适用于各种复杂EMI环境。
Based on ISO18000-6C standards, USB2.0 data communications protocol portable RF reader is designed. Altera EPIC3T144 is used as the core controller, （2C1100 as RF transceiver, and CH372 as USB device. Tests show the system transceiver carrier frequency is 889 MHz, maximum data transfer rate 240 kbps, antenna transmit power 1.1 dBm, and stable transmit distance about 1 m. Datatrans mission is accurate, and the system is stable and reliable with strong anti interference ability. It can be applied to all kinds of complex EMI environment.
