The invention belongs to the field of highway tunnel safe driving intelligent management, and particularly relates to a tunnel safety early warning system based on a directional millimeter wave radar technology. A tunnel safety early warning system based on a directional millimeter-wave radar technology is characterized in that a tunnel is segmented from a tunnel entrance to a tunnel exit according to the interval of 400 meters, and tail segments are abandoned to form n segments; a plane orientation millimeter wave radar facing the vehicle coming direction is arranged at the top of the tunnel at the end position of each section, and the detection area of the plane orientation millimeter wave radar covers the section of the tunnel; the method has the advantages that the plane directional millimeter-wave radar installed in the tunnel does not affect safe driving of vehicles in the tunnel, the plane directional millimeter-wave radar can track a plurality of vehicle targets in the section of the plane directional millimeter-wave radar at the same time, the plane directional millimeter-wave radar can cross a plurality of lanes to measure the speed of a plurality of vehicles and measure the distance between front and back vehicles, and meanwhile the lanes are scanned to find out road scattering. Related photos are captured to serve as evidences, and an early warning signal is displayed on the LED electronic screen.

    本发明属于高速公路隧道安全行车智能管理领域,具体涉及一种基于定向毫米波雷达技术的隧道安全预警系统。一种基于定向毫米波雷达技术的隧道安全预警系统,其特征是,从隧道入口起、沿车道按400米间隔分段直到隧道出口,舍去尾段共有n段;在每段结束位置的隧道顶部设置面向来车方向平面定向毫米波雷达,该平面定向毫米波雷达探测区域覆盖该段隧道;本发明的有益之处是,在隧道安装平面定向毫米波雷达不影响隧道内车辆安全行驶,平面定向毫米波雷达能同时跟踪自己段区的多个车辆目标,能跨多车道对多辆车辆测速,测量其前后车间距,同时扫描车道发现路面抛洒,抓拍相关相片留作证据,在LED电子屏上显示预警信号。
