Embodiment Construction

[0016] In the upstream of the road height limit section, the detection gantry, warning gantry and collision gantry are set in sequence, such as figure 1 shown. According to the safe passage height of the height-limited road section, according to the national standard GB5768-1999 "Road Traffic Signs and Markings" of the People's Republic of China, a limit height mark is attached to a detection mast. Displays with the words "Vehicle Super Height" composed of LED dot matrix are attached to the 2 warning masts. When an ultra-high vehicle passes through a detection door frame, the infrared beam is blocked, Figure 6 The middle circuit responds and sends out a prompt alarm, and the two warning masts display "vehicle overheight" at the same time. Once the driver cannot stop, the super-high vehicle will hit three collision masts and stop.

Abstract

The invention relates to an early warning portal frame system of an ultrahigh vehicle at a height-limited road section, comprising a detection portal frame, a warning portal frame and an impact portal frame. The safety height is marked on the detection portal frame and a shading detector is arranged on the detection portal frame. The warning portal frame is provided with an LED (Light Emitting Diode) dot lattice display for prompting the ultrahigh vehicle. The shading detector works by adopting an infrared shading principle. The impact portal frame is used for preventing the impact of the ultrahigh vehicle and a structure at the upper part of the height-limited road section. The invention reduces the possibility of the rigid impact of the ultrahigh vehicle, simultaneously reduces the secondary hazards of rear-end impact of vehicles, traffic jam and the like and has huge social and economic benefits.

Description

Technical field [0001] The invention relates to a mast system for prompting and warning super-high vehicles on a road height limit section. Background technique [0002] Common height-restricted road sections on the road include culverts and tunnels, road toll station scaffolding, road underpass interchanges when roads and railways intersect, ramps of different elevations in interchanges or road intersections, etc. Since the common feature of these road sections is that there are certain restrictions on the height of vehicles passing through, and the height restrictions are also different, so vehicles with relatively high loading heights may not be able to pass through the height-limited road section smoothly, and the upper part of the height-limited road section Structures collide. For this reason, the traditional method is to install a rigid mast in front of the height-limited road section, so that the super-high vehicle will collide with the rigid mast and stop. However...
