摘　　要：分析了青藏线应用G S M-R无线机车信号系统的原因和背景,无线机车信号系统分为连续式无线机车信号和接近连续式无线机车信号.以后者为例,从应用上分析其车站设备、车载设备及车地之间通信网络的结构和功能,总结G S M-R的无线机车信号系统的信息传输过程,其传输方式不受温度、海拔等环境因素影响,工作可靠性高,维修工作量很小,所以G S M-R在我国铁路通信中有广阔的发展前景.The reasons and background of applying GSM - R wireless cab signal system in Qinghai - Tibet Highway are analyzed that the wireless cab signal system can be divided into the cont.：nuous type and the close continuous type. Taking the later for example, the paper analyzes practically its station installations, vehicular equipment and the vehicle communication network structure and functions. It is concluded that G S M - R wireless cab signal system is intelligently transmitted, thus its transmission mode is independent on some envi- ronmental factors like temperature, elevation, thus the operational reliability is high, the service work load small. Therefore, G S M - R will have a broad prospect in developing in railroad correspondence.
