基于热成像技术的山区高速公路隧道车辆超温检测及预警系统设计

Design of Vehicle Over-Temperature Detection and Early Warning System in Mountain Highway Tunnel Based on Thermal Imaging Technology

系统安装在高速公路长隧道入口前,部署红外热能检测设备,用于实时监控过往车辆的车身温度分布。当发现超温车辆时即时通报给隧道管理所及上级单位,并通过与高速公路主线及隧道监控系统联动,调用信息发布设施向司机发布提示信息,引导司乘人员进入服务区或驶离高速及时停车处理,将事故隐患消除在隧道外,从而降低隧道火灾事故发生的概率,为隧道管理提供危险热源的主动探测能力,整体实现主动防护。

This system is installed in front of the long tunnel entrance of the expressway,equipped with infrared thermal energy detector,which is used to monitor the real-time temperature distribution of passing vehicles.When the vehicle with over-temperature is found,it will be immediately reported to the tunnel monitoring station and superior management unit.Through linking with the main line of the expressway and the tunnel monitoring system,it invokes the information release facilities to release the prompt information to the driver,and guide the driver to enter service area or get off the expressway to pull up,so as to eliminate a hidden danger outside the tunnel and reduce the probability of the tunnel fire accident.This system provides active detection capability of dangerous heat source for tunnel management,realizing overall active protection.
