上海城市轨道交通无线监测系统研究

Research on Wireless Monitoring System of Shanghai Urban Rail Transit

日益复杂的无线电磁环境给城市轨道交通无线设备的正常使用带来了很大的干扰,甚至会影响列车的运行安全。为此,建立一个适合上海城市轨道交通使用的无线监测系统,对可能出现的干扰进行预警,并在干扰产生影响后快速响应,显得尤为重要。通过对上海城市轨道交通无线监测的特点与需求进行深入研究,认为目前上海城市轨道交通无线监测的建设重点是采用移动监测的方法,对重点频段的电客列车加装车载监测设备。在上海轨道交通5号线部分正线区段应用该无线监测系统进行测试,验证了移动监测部分功能的可行性。

The increasingly complex wireless electromagnetic environment has brought tremendous interference to the normal use of urban rail transit wireless equipment,even to the safety of train operation.For this reason,it is particularly important to establish a wireless monitoring system suitable for Shanghai urban rail transit,to provide early warning of possible interference,and to respond quickly after the interference has caused impact.Through in-depth research on the characteristics and requirements of Shanghai urban rail transit wireless monitoring,it is believed that the current construction focus of Shanghai urban rail transit wireless monitoring is to adopt mobile monitoring methods and to install on-board monitoring equipment for electric passenger trains in key frequency bands.The wireless monitoring system is applied to part of the main line sections of Shanghai Rail Transit Line 5 for testing,which has verified the feasibility of mobile monitoring functions.
