Method for identifying container number by rail-mounted gantry crane

Abstract

The invention discloses a method for identifying a container number through a rail-mounted gantry crane. According to the invention, through coordinates of a secondary positioning lifting appliance (x, y, z) generated by the device in a gantry crane positioning system, through coordinate conversion, video equipment is controlled, the lifting appliance is automatically tracked, the container numberis accurately aligned, and the angle and the focal length of the video equipment are automatically adjusted, so that a video picture of the video equipment tracks a working focus in real time. Meanwhile, a gantry crane worker or a central control worker can control real-time pictures of the video equipment through the system, so that a container below the gantry crane can be clearly aligned. Thecontainer number below the gantry crane is recognized through the optical character recognition technology.

Description

technical field [0001] The invention relates to the technical field of container detection, in particular to a method for identifying a container number by a track-type door crane. Background technique [0002] Container number identification is a key technology for container yard management, and container location management is the core module. Since the location of the container number in the yard is dynamic, there is no system that can automatically obtain the container number at any location, so that The location management of containers has become a difficult problem. So far, there is no system in the market that can automatically identify the container number plate technology in the yard, and manual assistance is still required, resulting in low work efficiency and high costs. For this reason, the applicant proposes a A method for identifying container numbers by rail-mounted door cranes, combined with positioning technology, comprehensively obtains the container numbe...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a method for identifying the container number of a rail-type door crane, which has the advantage of real-time identification of the container number of the current operation, and solves the problem of not knowing the container number of the current operation when the door crane is used to transport the container. , making the execution of the job unclear and error-prone

At the same time, the central control center can accurately view the video of the current operating container in real time, which solves the problem that the central control center cannot be automated. At the same time, it has the combination of positioning system data to improve the location information management of the container yard.
