Height limit anti-collision warning system based on laser sensor

Abstract

The invention discloses a height limit anti-collision warning system based on a laser sensor. The system comprises an infrared laser transmitting and receiving device, an image collecting device, a wireless communication device and an alarm device, wherein the infrared laser transmitting and receiving device, the image collecting device, the wireless communication device and the alarm device are connected with a controller. The infrared laser transmitting and receiving device is arranged on a height limit anti-collision frame. The infrared laser transmitter of the infrared laser transmitting and receiving device is arranged on a driving device, and the driving device drives the infrared laser transmitter to horizontally rotate at a constant speed. The image collecting device collects an image when the infrared laser transmitting and receiving device receives infrared laser. The wireless communication device is used to communicate with an external terminal. The alarm device gives out analarm when the infrared laser transmitting and receiving device receives infrared laser. The device has a simple structure, can determine whether an object is over-high, and sends an over-limit alarmto a driver in advance.

Description

technical field [0001] The invention relates to a height limit anti-collision early warning system, in particular to a height limit anti-collision early warning system based on a laser sensor. Background technique [0002] At present, the height-limiting devices of many bridges and culverts are generally signs and guardrails, which achieve very limited warning effects. Accidents of bridges, culverts and other public infrastructure being damaged or damaged by vehicles occur from time to time, which not only affects traffic operation It also caused great personal and property losses, and the escape of some perpetrators after the incident also brought great difficulties to the investigation of the case. [0003] The Chinese patent literature with the notification number CN 107833494 discloses a bridge anti-collision alarm device, which monitors objects around the bridge pier through an ultrasonic transceiver device. When the distance between the ultrasonic transceiver (or ship...

AI Technical Summary

Problems solved by technology

[0004] 1. As long as there is an object close to the bridge pier, it will alarm, and the alarm is too frequent, resulting in a certain waste of energy

[0005] 2. And the alarm device can only remind, without other substantive measures, the effect is not good
