摘　　要：为全面优化轨道交通通信系统运行质量,提高信息交互管理水平,需要全面分析造成轨道交通通信系统出现电磁干扰的影响因素,从而结合实际情况落实相应的处理技术,合理抑制零线电磁干扰。同时,设置对应的处理器,抑制开关电源干扰问题,并合理选配不间断电源(Uninterruptible Power Supply,UPS)供电系统和全线路接地方式,有效维持轨道交通通信系统控制质量。只有完善处理机制和控制措施,才能共同促进轨道交通可持续发展。In order to comprehensively optimize the operational quality of the rail transit communication system and improve the level of information exchange management,it is necessary to comprehensively analyze the factors that cause electromagnetic interference in the rail transit communication system,and implement corresponding processing techniques based on actual situations to reasonably suppress zero line electromagnetic interference.At the same time,corresponding processors are set up to suppress the interference problem of switching power supply,and Uninterruptible Power Supply(UPS)power supply system and full line grounding method are reasonably selected to effectively maintain the control quality of rail transit communication system.Only by improving the handling mechanism and control measures can we jointly promote the sustainable development of rail transit.
