Description

Technical Field

[0001] The utility model relates to the technical field of intelligent traffic equipment, in particular to a height limit warning device for a road bridge. Background Art

[0002] Traditional road and bridge height limit warnings are usually implemented by hanging warning signs on roads and bridges or installing height limit devices not far from tunnel entrances, viaducts, flyovers, bridges, etc., while existing vehicle height limit devices on roads generally use a height limit rod set horizontally above the road. When the height of the vehicle exceeds the height of the height limit rod, when the vehicle drives to the height limit rod, the vehicle will be blocked by the height limit rod, thereby restricting the passage of vehicles whose height exceeds the height allowed for vehicles on the road.

[0003] At present, according to patent number CN206480149U, a road and bridge height limit warning device includes a height detection unit, a main control unit, a license plate recognition unit, a warning unit, a height limit frame and a power supply unit. The height detection unit includes a height measuring rod, an ultrasonic ranging module and a controller. The warning unit includes a voice alarm and an LED display screen. The controller is wirelessly connected to the wireless receiving module included in the main control unit through the wireless transmitting module included in it. The utility model can detect overheight vehicles in advance and promptly issue voice warnings and screen display warnings to the driver, so that the driver has ample time to take effective measures. The utility model is suitable for road and bridge height limit warnings.

[0004] However, the height limit warning device does not take into account the problem of the display screen being blocked by rain, snow and dust. Once the display screen is blocked by rain, snow and dust, it is easy for the driver to make misjudgments and cause safety accidents. Utility Model Content
