简论石太线GSM-R系统中弱场强产生的原因和处理方法

Discussion on the Causes of Weak Field Strength in GSM-R System of Shijiazhuang-Taiyuan Line and the Treatment Methods

以石太(石家庄—太原)高速铁路的GSM-R系统安装调试为例,介绍了GSM-R系统的概况,分析了弱场强存在的原因,提出了合理使用光纤直放站、基站和漏缆等解决弱场强问题的方法。

Taking the installation and debugging of GSM-R system of Shijiazhuang-Taiyuan High-speed Railway as an example,this paper introduces the general situation of GSM-R system,analyzes the causes why the weak field strength exists,and puts forward the method for solving the weak field strength through making rational use of fiber optic repeater,base station and leaky coaxial cable.
