地铁信号联锁系统与防淹门系统接口可靠性分析

Reliability Analysis of Interface between Metro Signal Interlocking System and Flood Gate System

当修建的地铁线路穿越江河、湖泊时,在进出水域的两端适当位置均需设置防淹门。为在防淹门区域灾害情况下保证列车与乘客的绝对安全,负责列车控制与安全防护的地铁信号系统必须与防淹门系统设置接口,实现列车控制与防淹门控制的联动功能,并保证各系统接口的安全可靠。为此,此文以杭州地铁4号线两车站所设防淹门为例,对与信号系统间所设接口电路的可靠性进行了分析与计算。

When the subway line across the river and lake,the flood gate should be installed in the proper position at both ends of inlet and outlet. In order to ensure the absolute safety of trains and passengers in the case of flood gate area disaster,the interface between the subway signal system for train control and safety protection and flood gate system must be set up to realize the linkage function of train control and anti flood door control. And that also can ensure safety and reliability of system interface. Therefore,taking the flood gate of two stations of Hangzhou Metro Line 4 as an example,the reliability of interface circuit between signal system and signal system is analyzed and calculated.
