摘要
介绍一种测控系统数据无线传输方法,该系统采用专用射频芯片nRF0433,工作于ISM频段,采用FSK调制方式,以串行通信方式实现了数据的半双工无线传输,传输距离可达200米,具有抗干扰能力强的特点。并就其在铁路货场中的应用作了介绍。
This paper introduces a method to transfer data in wireless for the measuring & controllingsystem. This system adopts a special RF IC of nRF0433 to implement the semi-duplexdata transfer in wireless. It operates in ISM frequency band and uses FSK mode totransfer data by serial format. Its available scope is 200 meters. This system achievesperfect performance of anti-interference. And its application in the railway cargo is alsointroduced.
