Vehicle height excess detecting and alarming device

Abstract

The invention relates to a vehicle height excess detecting and alarming device. The device comprises a main controller, a power supply, a vehicle image shooting and license plate number recognition system, a laser signal transmitter, a laser signal receiver, an alarming display system and a remote communication system, wherein the remote communication system is communicated with the main controller in wireless communication modes of global system for mobile communication (GSM) and general packet radio service (GPRS) so as to transmit and receive information; the power supply is a solar power supply system, and comprises a solar panel, a solar controller, an inverter and a storage battery pack; the vehicle image shooting and license plate number recognition system comprises a camera; and avideo acquisition card is arranged in the housing of the main controller. The device has the advantages that: the device can accurately and reliably detect the height excess of a vehicle and has the license plate recognition rate of over 95 percent to a super high vehicle, the recognizing time is less than 0.4s, and the electronic light emitting diode (LED) display screen of a large screen is clear and striking and can be seen in the distance of over 100 meters; and the main controller runs reliably and adapts to outdoor extremely-high or extremely-low temperature using environment.

Description

technical field [0001] The invention relates to a vehicle over-height detection and alarm device, which belongs to the technical field of detection and control, and is suitable for use in various occasions with height restrictions on passing vehicles, and is especially suitable for over-height detection of vehicles at the entrances of overpasses, tunnels, culverts, etc. High detection and alarm prompt. Background technique [0002] With the rapid development of transportation, various forms of highway overpasses, tunnels, culverts, railway bridges, etc. have appeared in large numbers. While people are trying to improve the convenience and comfort of traffic, they also begin to pay more attention to the safety of traffic. Among them, the safety of bridges, tunnels, and culverts is a part that cannot be ignored. The safety issues of bridges, tunnels, culverts, etc. involve many aspects, among which, the harm caused by the impact of super-high vehicles on them is a part that ...

AI Technical Summary

Problems solved by technology

In order to prevent super-high trucks from directly hitting bridges, tunnels, and culverts, the transportation department has also thought of many countermeasures, such as hanging height-limit signs and setting up height-limit railings, etc., but these measures failed to solve the problem fundamentally. Railings, or stuck under the railings, unable to advance and retreat, blocking traffic, and even damaging the safety of drivers' lives and property happens from time to time

The crux of the problem is that in many cases, the driver of a super-high vehicle cannot accurately judge whether the vehicle he is driving is super-high or not.
