摘要
车-地无线通信传输是地铁信号系统中车与地实现信息互传的一种重要方式。但如何确保数据传输在该方式中的安全可靠,则是信号系统的一个重要议题。针对该项议题,采用分析和列举的方法,通过对车-地无线通信传输的安全性需求进行分析,列举出当前在地铁运营和建设中存在的几种主要的车-地无线通信传输干扰源,同时针对各干扰源提出了几种切实可行的安全防御措施。经实践表明,各措施抗干扰效果良好,其可以作为解决各地铁建设中信号系统车-地无线通信传输抗干扰的措施来应用。
Train-wayside wireless communication is an important way in metro signal system to realize information transmission between the train and the earth.But how to ensure the safety and reliability of data transmission in this manner is one of the important topics in signal system.Aiming at this topic,using the analysis method and enumeration method,the paper analyzes the safety requirements of train-wayside wireless communication.Further,the paper enumerates several main interference sources in the transmission of train-wayside wireless communication in metro construction and operation at present.Focusing on each interference source,the paper puts forward several feasible safety precaution measures.The actual practice shows that these measures of anti-interference have good effects,and also they can be used as the solutions to anti-interference in train-wayside wireless communication system for every metro's project.
