摘　　要：本文通过对天津地铁某线路中400V系统通信组网方式及通信原理的研究,找出了该线路400V系统遥信上传时间长、响应慢这一问题的根本原因。并结合现场实践,给出了问题的解决方案,该解决方案在实际运用中,收到了良好的效果,将400V遥信上传时间由原来的9-24秒不等,缩短到2秒内,极大的提高了遥信响应速度。同时也给地铁调度中心的快速应急处置提供了技术支持,避免了因信息上传延时对地铁运营造成的风险。对今后地铁建设中的类似问题,有较强的预防借鉴作用。Through the research on the communication networking and communication principle of a 400 V system in Tianjin Metro, this paper finds out the root cause of the slow response which the 400 V system’s remote signal. In combination with field practice, a solution to the problem is given. In practice, the solution has received good results. The 400 V remote signal upload time has been reduced from 9-24 seconds to 2 seconds. Greatly improved the response speed of remote signal. At the same time, it also provides technical support for the rapid emergency disposal of the subway dispatching center, and avoids the risks caused by the delay of information upload to the subway operation. It has a strong preventive and reference effect on similar problems in the future subway construction.
