The invention provides a highway tunnel traffic safety risk identification and prevention and control system which comprises an entrance looped network switch, a radar velocimeter arranged outside a tunnel entrance, a visible light and infrared all-in-one machine, an information board and a flexible water curtain blocking subsystem arranged at the tunnel entrance. The local industrial personal computer identifies whether the vehicle is in an abnormal state or not according to the vehicle speed, the vehicle driving video and the vehicle infrared thermal imaging image; if abnormity exists, the local industrial personal computer pushes alarm information to the information board and the flexible water curtain blocking subsystem, and meanwhile, the vehicle license plate number and the alarm information are pushed to the cloud platform through the wireless routing gateway; radar speed measurement, video recognition and thermal imaging technologies are integrated, the technical problem that operation safety accidents in a tunnel hole cannot be reduced or prevented from risk sources at present can be solved, abnormal vehicles with potential risks can be monitored, early warned and blocked, and traffic accidents in the highway tunnel can be reduced.
本发明提供一种公路隧道行车安全风险辨识与防控系统,包括:入口环网交换机,设于隧道入口外的雷达测速仪、可见光红外一体机、情报板,设于隧道入口处的柔性水幕阻拦子系统,本地工控机根据车辆车速、车辆行车视频、车辆红外热成像图像对车辆是否存在异常状态进行识别;若存在异常,本地工控机向情报板、柔性水幕阻拦子系统推送告警信息,同时通过无线路由网关推送车辆车牌号和告警信息至云平台;本发明融合雷达测速、视频识别和热成像技术,可以解决目前不能从风险源上减少或阻止隧道洞内运营安全事故发生的技术问题,实现对具有潜在危险的异常车辆进行监测、预警和阻拦,可减少公路隧道内交通事故的发生。
