Vehicle height detection and height exceeding alarm device and method

Abstract

The invention discloses a vehicle height detection and height exceeding alarm device and method. The device is composed of a support, a power supply module, a main control module, a detection module, a trigger module and a display alarm module; and the trigger module, the detection module, the main control module, and the display alarm module are connected in sequence. The support provides a mounting platform for the power supply module, the main control module, and the detection module. In addition, the method comprises: when a vehicle approaches the device, the trigger module triggers the device to work; when the vehicle passes by the device, the main control module carries out fusion processing on measuring values returned by a plurality of laser ranging modules to obtain a vehicle height value and first-time vehicle height exceeding detection is carried out; and after the vehicle passes by the device, the main control module carries out second-time height exceeding detection on the vehicle according to a switching signal of a photoelectric switch sensor and transmits the vehicle height value and the two height exceeding detection results to the display alarm module. Therefore, non-contact measuring of the vehicle height is realized; the accuracy is high; the cost is low; the reaction sensitivity is high; and the real-time performance is excellent.

Description

technical field [0001] The invention relates to the technical field of road vehicle height detection, in particular to a vehicle height detection and super-height alarm device and method. Background technique [0002] With the three-dimensional development trend of urban traffic, there are more and more traffic facilities such as viaducts and tunnels. In view of the damage to structures such as bridges and tunnels and the loss of life and property of drivers caused by super-high vehicles running on the road, the traditional method is to install a height-limited gantry on roads with limited height requirements, but this method cannot clearly indicate whether the vehicle is It is already super high, and collision accidents are not uncommon, so it is urgent to develop a new type of vehicle super high active warning device to effectively remind the driver to avoid and reduce the occurrence of traffic accidents such as hitting bridges and getting stuck in bridges. [0003] At pr...

Problems solved by technology

However, due to the different height limit standards of various road sections in the city, the above super-height detection device can only judge whether the vehicle is super high, and the driver cannot obtain accurate height information of the driving vehicle. There is still a risk of collision on high roads
