Bridge anti-collision monitoring device based on laser scanning

Abstract

The invention discloses a bridge anti-collision monitoring device based on laser scanning. The device comprises a laser scanning sensor, video monitoring equipment, a host and an alarm. The laser scanning sensor is arranged on a bridge beam body or pier and used for acquiring basic information of a target, and the basic information is transmitted to the host, wherein the basic information comprises ultrahigh marks and contour features; the host judges whether the target is ultrahigh or not according to the ultrahigh marks, and whether the target is a ship or not is further judged according tothe contour features, wherein when it is judged that the target is ultrahigh and is the ship, the host controls the video monitoring equipment to photograph or shoot the ship, and the host controls the alarm to transmit early-warning or alarming signals. Whether the ship is ultrahigh or not can be detected only through the laser scanning sensor, whether the ship is in the risk of colliding with the beam body or not is recognized, and the monitoring device is simple and high in reliability.

Description

technical field [0001] The invention relates to the technical field of bridge anti-collision, in particular to a bridge anti-collision monitoring device based on laser scanning. Background technique [0002] At present, with the rapid development of transportation, it is necessary to build a large number of bridges on the river or sea, followed by frequent accidents of ships colliding with bridges, which may even lead to serious accidents such as bridge collapse, ship sinking, and human death. It has caused heavy losses to society and economy. [0003] In view of the above-mentioned bridge collision accidents, there are currently two types of bridge anti-collision measures: [0004] 1. Install passive anti-collision devices on bridges [0005] When the ship hits the bridge, measures such as energy absorption are adopted to minimize the impact of the ship on the bridge, thereby reducing the serious consequences of the ship hitting the bridge accident. However, the adoption...

AI Technical Summary

Problems solved by technology

[0012] 1. The use of laser beams will cause false alarms for obstacles in the optical path and the application is limited;

[0013] 2. The reliability of bridge anti-collision warning system using image processing technology dependent on weather and other conditions or using water level sensor combined with laser scanning range finder is low
