摘　　要：为了有效评估地铁无线控制系统的安全性,将轨道交通控制系统的无线通信作为研究对象,利用三维电磁仿真软件(HFSS)设计DCS系统车载双八木天线,创建在地铁双八木天线辐射下司机室高频电磁环境的模型,数值模拟天线在安全距离的耦合性.仿真结果表明,车顶天线相距2000mm时,互干扰度最小,能够保证CBTC系统无线通信的安全稳定性.In order to effectively evaluate the safety of subway wireless control system,we will take the wireless communication of rail traffic control system as the research object,design ofDCS vehicle double yagi antennas using 3D electromagnetic simulation software （HFSS）. The system creates a double Yagi antenna model in the environment of high frequency electromagnetic radiation in cab. The simulation data shows the coupling of antennas in safe distance. Simulation results show that the mutual interference is the least when the roof antenna is 2000mm,it can ensure the safety and stability of CBTC wireless communication system.
