Height limiting device and system for preventing vehicle top from being cut and height limiting method thereof

Abstract

The invention discloses a height limiting device and system for preventing a vehicle top from being cut and a height limiting method thereof. The height limiting device comprises speed and height measuring marker posts and a height limiting frame, wherein measurement information is sent to a background computer after the speed and height measuring marker posts measure the speed and height of a running vehicle, and the background computer judges the speed and height of the vehicle and then sends an instrument to the height limiting frame. The height limiting frame comprises vertical supporting rods, a cross rod, a baffle plate, a baffle plate rotation driving assembly and a dye spraying assembly, wherein the vertical supporting rods are arranged on two sides of a road at intervals, the cross rod is arranged between the vertical supporting rods, two ends of the baffle plate are rotatably connected to the two vertical supporting rods, the baffle plate rotation driving assembly is connected to one end of the baffle plate, and when a vehicle with the height exceeding the height limit passes through, the baffle plate rotation driving assembly drives the baffle plate to rotate, and the dye spraying assembly arranged on the baffle plate sprays a dye to the vehicle top so as to warn a vehicle driver. The top is prevented from being cut by adopting the rotation structure design of the baffle plate. In addition, warning is performed in dye spraying, shooting and recording modes.

Description

Technical field [0001] The invention relates to the field of transportation, in particular to a height-limiting device, a system and a height-limiting method for preventing a vehicle from being cut top. Background technique [0002] Elevation limit rack is an auxiliary tool for road traffic control. Elevation limit racks are divided into three types: fixed limit rack, manual limit rack, and electric limit rack. They are used for portal frames at the entrances of bridges, culverts, and tunnels. They are generally welded with steel structures. It plays the role of protecting bridges, culverts, and tunnels; there are signs on it, indicating the number of meters in height, to remind vehicles. The height limit is marked on the road to limit the height, but when the vehicle is actually driving, the driver may not be able to accurately remember the precise height of the vehicle that he is driving. In addition, when the vehicle is carrying a lot of objects and the objects are higher than...

AI Technical Summary

Problems solved by technology

There is a road limit passing height marked on the height limit shelf, but when the vehicle is actually driving, the driver may not be able to accurately remember the exact height of the vehicle he is driving. It will cause the driver to make an error in judging the height of the vehicle. If the height of the vehicle is higher than the height limit, the driver will be blocked by the height limit when the driver makes a judgment error. If the vehicle speed is faster, the vehicle may be restricted. In the case of elevated roof cutting, the existing height-limiting racks cannot effectively solve this problem
