Container-truck positioning system and method for container crane

Abstract

The invention discloses a system and method for aligning trucks of a container crane. The images of the trucks are captured in real time by an image camera device arranged above the loading and unloading position of the crane, and the images are transmitted to an image processing computer, which uses the pre-stored crane to simulate the spreader The outline is synthesized in the digital image, and the synthesized image is output to the display controller in real time through the network, and the display screen installed in front of the loading and unloading position of the crane is controlled to display the synthesized image in the field of vision of the truck driver, helping the driver to complete the pre-positioning of the truck; At least one set of laser scanning equipment is installed on the front and rear beams of the crane to collect the outline information of the truck or the container on the truck, and transmit it to a computer system to perform data filtering and feature fitting on the outline information and communicate with it Comparing the theoretical setting values, analyzing the positioning error value of the truck or container relative to the crane, and transmitting it to the error display screen in front of the loading and unloading position of the crane for display, helping the driver to complete the precise positioning of the truck.

Description

technical field [0001] The invention relates to a container crane, in particular to a method and a system for aligning the truck with respect to the position of the spreader when the truck is loaded and unloaded under the container crane. Background technique [0002] The development of the container shipping industry has put forward higher and newer requirements for the technology of container cranes; improving the productivity of operations and reducing the labor intensity of operators is an eternal subject of the development of container crane technology. [0003] The loading and unloading of containers between container cranes and ground container trucks is a bottleneck that restricts the efficiency of container terminal loading and unloading. How to improve the alignment speed between crane spreaders and container trucks to improve loading and unloading efficiency is a key issue for port crane manufacturers and related technologies. What experts have been working on. ...

AI Technical Summary

Problems solved by technology

Therefore, the proficiency and operating experience of the truck driver determine the alignment speed of the spreader and the loading and unloading speed of the crane to the truck. If the driver is not skilled, the spreader is in place and the truck moves back and forth. Or the situation that unmanned cranes and manned trucks cannot cooperate at all, which seriously affects the operation productivity of container automated terminals
