摘　　要：在宜万铁路通信系统工程中,复线段采用GSM-R通信系统,单线段则采用无线列调通信系统,由于2种系统采用的频率及工作方式存在差别,在区间切换的问题就成为影响列车运行安全的重要因素,阐述了2种无线通信系统如何在不影响行车安全以及保证列车运行的状态下,更好地衔接与切换的方案。In Yichang-Wanzhou Railway communication system engineering,the complex line using GSM-R communication system.the single line using of wireless train dispatching communication system.Because the two systems differ in frequency and working mode,and the problem of both systems on interval switching has an important impact on the safety of train operation.The following briefly illustrates the program how the two types of wireless communication system,without affecting the satety of driving and train operation,make the connection and switching between the two systems better.
