双鉴探测应用于地铁屏蔽门的分析

站台屏蔽门系统是轨道交通中的一种重要设施，可以最大限度地保证旅客安全乘坐地铁或轻轨列车，但是地铁屏蔽门夹人或挤人事故仍时有发生，而影响屏蔽门安全的主要因素是探测系统不够完善，因此，提出引入红外微波双鉴探测技术来改进现有屏蔽门探测系统，以提升屏蔽门探测系统的准确性从而精确控制开关门过程，减少当前地铁屏蔽门系统夹人事故的发生。

Dual technology detection used in metro platform screen door

Platform screen door system is one of the important rail transit facilities, which can effectively ensure passenger safety in metro or light rail-train. But the folder accidents in platform screen door still occur. The main factors affecting the platform screen door security is the unperfected detection system, as a result, an infrared microwave dual technology detector is adopted to improve the platform screen door system in order to precisely control the switch, and reduce the occurrence of folder accidents.
