摘要:
［目的］地铁区间消火栓系统出现爆管等漏水事故时，列车控制室直接远程关闭消火栓系统进区间主管上的电动阀门，导致整个区间消火栓系统处于无水状态，给运营带来较大安全隐患，故有必要对地铁区间消火栓系统爆管点定位系统进行研究。［方法］提出了在区间消防立管上增加电磁流量计和电接点压力表，以实现爆管点的精确定位的方案。同时，通过BAS(环境与设备监控系统)联动控制，以最快速度远程关闭爆管点前后的电动阀门，从而将对区间消防系统的影响降至最低。阐述了地铁区间爆管点定位系统的总体架构，包括感知层、网络层和应用层三部分。［结果及结论］建立爆管点快速定位系统，远程关闭爆管位置前后阀门，最大程度地减少无消火栓系统保护地段及地铁停运时间，实现地铁区间在爆管等事故发生后的正常运营。
Abstracts:
［Objective］ When water leakage accidents like pipe bursts occur in the fire hydrant system of metro intervals, the train control room will directly close the electric valves on the main pipeline remotely, cutting off water supply to the entire interval fire hydrant system. This results in significant safety risks for operations. Therefore, it is necessary to study a positioning system for burst pipe points in metro interval fire hydrant systems. ［Method］ A solution is proposed to install electromagnetic flowmeters and electric contact pressure gauges on interval fire protection risers to enable precise positioning of burst pipe points. Additionally, through linkage with the BAS (building automation system) for environmental and equipment monitoring, electric valves before and after the pipe burst point can be closed remotely and swiftly, minimizing the impact on the interval fire protection system. The overall architecture of the positioning system for burst pipe points in metro intervals is outlined, comprising three layers: perception layer, network layer, and application layer. ［Result & Conclusion］ A rapid positioning system for burst pipe points is established, enabling the remote closure of valves before and after the burst point location. This approach could minimize unprotected sections of the fire hydrant system and the metro service downtime, ensuring the metro interval resumes normal operations promptly following accidents such as pipe burst.
