基于微结构光纤分布式传感的铁路隧道门智能防护技术研究

铁路隧道防护门是隧道防灾救援专题的重要分支, 对行车安全有着重要的影响。文中研究一种基于微结构光纤分布式传感(MFDS)的新型铁路隧道防护门智能监测技术, 可以实时监测防护门的状态与检测运行故障, 当发现防护门出现异常状况时及时报警, 显示并记录报警部位和报警资料以及实现报警信号远程传送。通过研究, 针对铁路隧道防护门设计得出以下结论: (1) 防护门布置应采取远离隧道中心布置的方案; (2) 防护门隔墙应采用混泥土隔墙; (3) 防护门应朝疏散方向开启; (4) 设计防护门外沿距离相邻线路中心线距离应考虑防护门门框高度和车辆建筑限界。论文提出一种新颖的铁路隧道防护门设计方案, 对于铁路隧道防护门设计与维护相关工作具有重要指导意义。

Abstract

Protective doors of railway tunnel is an important branch of the tunnel disaster prevention and rescue project and has an important influence on safety. A novel innovative protective railway tunnel door based on the micro-structure fiber distributed sensor(MFDS) was studied in this paper, which could be used for the alarm system, the display and recording of alarm parts and alarm data, detection of operational failure and alarm signal remote transmission function. The following research results are reached: (1) the arrangement scheme of protective doors should be taken away from the center line of tunnel; (2) the partition wall of the protective door is made of beton; (3) the door should be opened in the direction of evacuation; (4) when designing the distance between the outside of protective door and central line of adjacent lines, we should consider the frame height of protective door and vehicle clearance. The research results can provide guidance for the design of protective doors for railway tunnel to a certain extent.
