摘要
结合高速公路应急电话系统的开发和研究，介绍了一种适用于较少数据量和较远传输距离（１０ ｋｍ以上）的点对多点的远程数据传输系统的硬件电路及其软件实现．此系统不仅适用于高速公路应急电话系统，也可用于各种远距离测量或监控系统．
Based on the research of expressway emergency system, the paper introduces a point-to-points telecommunication system(circuit and software),which can be used to transport some data over a long distance (more than 10 kilometers). The system not only can be used in expressway emergency system, but also can be used in tele-measure and tele-control system.
