The invention provides an intelligent laser stop line applied to foggy days, which comprises a plurality of red laser light-emitting units, a plurality of green light-emitting units and a visibility sensor, the red laser light-emitting units and the green light-emitting units are uniformly distributed and welded on a rectangular circuit board, and the visibility sensor is welded on the circuit board at the same time. The parking line is installed in a parking line shell and integrally embedded in a road surface. When the air visibility is reduced, aerosol is formed, and meanwhile, the visibility sensor is connected with a circuit; when passing is forbidden, the red laser light-emitting unit is lightened, and a red light wall is formed through the Tyndall effect; when passing is allowed, the red laser light-emitting unit is extinguished, the green light-emitting unit is lightened, a common light source is emitted, the red light wall disappears, but the parking line emits green light to indicate traffic. The visible distance of the parking line in weather with low visibility is lengthened to a certain extent, the deterrent force of the parking line is increased, and the traffic pressure in extreme weather is further relieved.
本申请提供一种应用于雾天的智慧激光停车线,包括红色激光发光单元、绿色发光单元、能见度传感器,若干所述红色激光发光单元和所述绿色发光单元均匀排布焊接至长方形线路板上,所述线路板上同时焊接所述能见度传感器,安装于停车线壳体内,整体镶嵌于路面内;空气能见度降低时,形成气溶胶,同时所述能见度传感器接通电路;禁止通行时,所述红色激光发光单元点亮,通过丁达尔效应形成红色光墙;允许通行时,所述红色激光发光单元熄灭,绿色发光单元点亮,发射普通光源,红色光墙消失,但停车线为绿色发光,指示交通。在一定程度上加长了停车线在能见度较低天气下的可见距离,增加停车线威慑力,进而减轻了极端天气下交通的压力。
