Walking positioning, deviation correcting and collision preventing method for tire crane

Abstract

The invention discloses a walking positioning, deviation correcting and collision preventing method for a tire crane. According to the method, by installing laser scanners on four support columns of the tire crane respectively for detecting the gaps between the side faces of containers and the gaps between containers in a container yard, walking positioning of the tire crane, positioning of the containers in the yard, automatic deviation correcting and collision preventing warning are achieved. The laser scanners, the containers, a computer, a warning device, a container position management displayer (cab management system interface terminal) and a rain cover are involved in the method. The laser scanners are installed on supports in front of four support column tires of the tire crane respectively and can rotate along with rotation of the tires. With the gaps between the side faces of the containers and the gaps between the containers in the container yard as the reference, the laser scanners are installed in the rain cover, the computer is installed in an electrical room, and the warning device is installed in a cab of the tire crane. The laser scanners, the warning device and the container position management displayer are all connected with the computer, and the computer is connected with a tire crane PLC and participates in walking control over the tire crane.

Description

Technical field [0001] The invention relates to container lifting, positioning, walking deviation correction and walking collision avoidance of a tire crane used in container loading and unloading operations, and is particularly suitable for container loading and unloading operations of tire crane lifting. Background technique [0002] At present, the detection methods for rectification and collision avoidance of container tyre cranes include GPS positioning automatic correction method, single-point laser rangefinder combined with reflector automatic correction method, image processing correction and manual correction, but these methods have their own shortcomings. GPS positioning is susceptible to artificial data tampering, which leads to data errors and needs to be corrected regularly. The single-point laser rangefinder combined with the reflective plate automatic correction method requires a long reflective plate to be installed on the side, which is not practical. Image proc...

AI Technical Summary

Problems solved by technology

GPS positioning is vulnerable to artificial data tampering, which leads to data errors and needs to be corrected regularly

The single-point laser rangefinder combined with the automatic deviation correction method of the reflector needs to install a long reflector on the side, which is not practical

Image processing correction is easily affected by weather and light, and the stability is not enough

The driver of the tire crane adjusts the direction of the wheel, that is, manually corrects the deviation. This method has low precision and may easily cause driver fatigue.
