摘　　要：针对无线通信在测控领域的优越性,基于无线射频收发模块PTR8000,采用分层结构,利用特殊的通信协议实现了一种传输可靠、扩展方便、使用灵活的无线数据通信系统。介绍了无线射频模块PTR8000的结构、工作模式、射频收发流程以及片内SPI接口的配置,在此基础上分析了系统的硬件设计和软件设计。基于PTR8000的无线通信系统具有功耗低,多频道多频段的特点,可以很方便地实现点对点及点对多点的无线通信,可应用于遥感、遥控、无线抄表、工业数据采集及家庭自动化等领域。Be aimed at the advantage of wireless communication in the field of measurement and control, based on radio frequency transceiver PTR8000, adopting stratified structure, using special communication protocol, achieves a wireless data transmission system that is reliable to transmit, convenient to expand, and flexible to use. This paper introduces the structure of wireless RF transceiver PTR8000, and its operation process, SPI interface configuration,then analyzes harware and software design of the system. The wireless system based on PTR8000 has many advantages such as low power dissipation, Multi-channel, and multi-band. It can be achieved point-to-point and point-to-muhipoint wireless communications easily, and is used in remote sensing, remote control, wireless meter reading, Industrial Data Acquisition and home automation and so on.
