System and method for detecting hoisting prevention on basis of laser

Abstract

The invention discloses a system and a method for detecting hoisting prevention on the basis of laser. The system comprises a logic operation unit, a laser scanner and a PLC (programmable logic control) system. The laser scanner and the PLC system are connected with the logic operation unit. Compared with the prior art, the system and the method have the advantages that the locations of lifting appliances, containers, trucks and the like can be detected by the aid of laser scanning ranging principles and pattern recognition and automatic control technologies in real time, running of lifting mechanisms can be controlled according to safety control strategies, the system has functions of preventing the trucks from being hoisted, and accordingly production accidents can be prevented; the side contours can be continuously scanned and recognized during operation on the containers, accordingly, hoisted states of the trucks can be accurately judged, and the container loading and unloading safety can be greatly enhanced.

Description

technical field [0001] The invention relates to a laser-based anti-lifting detection system and method, which is applied to the container gantry crane equipment of the container terminal to detect in real time the separation state of the trailer and the container during the operation of the foreign collection truck, so as to protect the collection truck from being damaged due to The lock on the trailer was not separated from the container, which caused the collection truck to be lifted by the gantry crane (ie RTG) by mistake. Background technique [0002] During the operation, one of the main safety hazards of RTG lifting is that the container and the truck are lifted together or half-lifted because the lock pin of the truck is not fully opened, which is usually called a truck accident. [0003] At present, the safety detection and protection system for anti-lifting trucks on the market mainly uses photoelectric switch devices to detect whether the space between the containe...

AI Technical Summary

Problems solved by technology

[0003] At present, the safety detection and protection system for anti-lifting trucks on the market mainly uses photoelectric switch devices to detect whether the space between the container and the trailer is safe to separate when the container is hoisted to a certain distance. Such a device It completely depends on the encoder data calculation, and is affected by the height of the truck trailer, there is also great uncertainty in the detection of box car separation, which cannot meet the needs of safety
