摘要
西煤东运是我国的一项基本国策。文中针对西煤东运的某地方重载铁路,采用调制解调芯片CMX469A,进行了列尾装置的无线通信模块的设计。论文阐述了硬件电路设计、软件通信协议和差错控制编码技术。该设备目前已投入运行600余趟次,累计约15万公里,通信成功率高于国内其他同类产品,论证了该设计的可靠性。
As we all know,it is a basic national policy to carry the coal from the west to the east.In this paper,we have designed a wireless communication system of End-of-train safety equipment for a local heavy freight railway,which is based on a modem chips IC-CMX469A.This paper illustrated the design of hardware,software communication protocol and error control coding technology.Finally,the equipment have run more than 600 times,which accumulated about 150000 kilometers,and showed a superior performance than others,which proved the success.
