北京地铁5号线调试期间TCOM宕机的解决方案

Solution to TCOM Downtime During Commissioning of Beijing Metro Line 5

北京地铁5号线信号系统低频发码改造工程调试期间利用倒切开关对运营线路信号系统进行改造,由于无法在常规非运营时间的一个晚上完成本设备集中站的所有调试,所以新增LFCT设备与既有TCOM设备存在共存期,从工程实施以绝对不影响既有设备运营安全和服务水平为前提,研究既有TCOM设备情况,分析得出调试期间TCOM系统宕机的解决方案。

During the commissioning of the low-frequency coding reconstruction project of the signal system of Beijing metro line 5, the signal system of the operating line was reconstructed by using the reverse switch. Since it is impossible to complete all the comissioning of the centralized station with this equipment in one night during the normal non-operating time, there is a coexistence period between the newly added LFCT equipment and the existing TCOM equipment. This paper studies the situation of the existing TCOM equipment on the premise of absolutely not affecting the operation safety and service level of the existing equipment, and analyzes and obtains the solution to the downtime of the TCOM system during the commissioning.
