摘要
城市轨道交通部分线路的信号系统服役接近15年,信号系统改造迫在眉睫。传统的改造方案施工难度大、施工周期长、涉及设备多。提出一种分段式的改造方案,可降低成本提升效率,尽早解决既有车载设备故障率高给运营带来的影响。
As the urban rail transit signaling systems of some subway lines have been in service for nearly 15 years,there is an urgent need to retrofit such signaling systems.The traditional retrofitting solution has such problems as huge construction difficulties,long construction period,large amount of involved equipment.Thanks to technical development,it is possible to reduce the retrofitting costs of signaling systems.The paper provides a phased retrofitting solution,which can not only reduce the costs and increase the efficiency,but also eliminate as soon as the negative impacts of the failure rate of existing onboard equipment on subway operation.
