The invention relates to a tunnel safety warning system. A tunnel safety warning system is characterized in that measuring nodes are arranged from an entrance of a tunnel to an exit of the tunnel at intervals of 100 meters along a lane, and the total number of the measuring nodes is n after rounding; rear correlation echelette gratings are erected on the two sides of the tunnel at the first measuring node of the lane, and front correlation echelette gratings are erected at the positions 5 meters right ahead of the rear correlation echelette gratings in the lane direction; an MCU minimum system is arranged on the 25-meter lane side in front of the front correlation echelette grating, a road-crossing LED electronic screen is arranged on the 25-meter tunnel top in front of the front correlation echelette grating, and a license plate snapshot machine and a vehicle camera are arranged on the two sides of the road-crossing LED electronic screen. The bijection infrared grating has the beneficial effects that the driving safety is not influenced by mounting the bijection infrared grating, the bijection infrared grating is low in price, the bijection infrared grating can cross two lanes, the bijection infrared grating is convenient and fast to mount, the infrared grating is high in electromagnetic interference resistance, reliable in work, capable of stably working for a long time without maintenance, and low in use cost.
本发明涉及一种隧道安全警示系统。一种隧道安全警示系统,从隧道入口起、沿车道按100米间隔设置测量节点直到隧道出口,取整后共有n个测量节点;在车道第1个测量节点处的隧道两侧架设后对射红外光栅,沿车道方向在后对射红外光栅正前方5米处架设前对射红外光栅;在前对射红外光栅前方25米车道侧设置MCU最小系统,在前对射红外光栅前方25米隧道顶设置跨路LED电子屏,在跨路LED电子屏两侧设置车牌抓拍机和车辆摄像机;本发明的有益之处是,安装对射红外光栅不影响行车安全,对射红外光栅价格便宜,能跨双车道安装方便快捷,红外光栅抗电磁干扰强,工作可靠能长期稳定工作不用维修,使用费用低。
