摘　　要：为了解决有线数据传输的线路布放和数据通信接口问题,方便仪器设备之间的连接,设计了一种基于USB接口的嵌入式无线传输系统。系统把新一代USB接口芯片CP2101与低功耗RF收发芯片CC1101相结合,采用单片机控制,通过自主灵活的通信协议和全球ISM频段通信标准,以及高效前向纠错信道编码技术,实现了中短距离内准确、稳定、高速的数据传输。In order to solve problems of laying out for wired data transmission and interface data communication, and to facilitate the connection between the instruments and equipment, an embedded wireless transmission module system based on USB interface is designed. It combines the new generation USB interface chip CP2101 with the low-power RF transceiver chip CCll01, and uses the MCU to con- trol. Through the autonomous and flexible communication protocol and the global [SM band communications standards, and the technology of efficient forward error correction channel coding, accurate, stable, high-speed data transmission in a short distance is achieved.
