Container crane spreader to container guidance system

Abstract

The invention discloses a container crane sling aligning guide system which greatly facilitates a driver's remote container aligning work, improves the degrees of the numeralization, informatization and intelligentialization of a crane, and has great application expansibility. The container crane sling aligning guide system adopts a technical scheme as follows: through an image processing technique and a position data fitting technique as well as a 'frame aligning' method, the original sling image viewed by a remote driver performing the remote container aligning work is processed and converted into a target frame and a present sling frame comparison display manner, and work data instruction is accompanied, and the sling falls into the target frame, and accordingly, the successful container aligning is shown.

Description

technical field [0001] The invention relates to equipment on a container crane, in particular to a container crane spreader automatic system for container alignment. Background technique [0002] Container terminal automation is the technical development direction generally sought by container terminals at home and abroad after nearly 20 years of rapid development of container handling and transportation. According to statistics, there are more than 40 automated terminals that have been built or are under construction. Container terminal automation has many benefits, such as increasing the stability and predictability of terminal operation, improving equipment utilization, reducing labor costs, improving safety and driver comfort, etc. [0003] Compared with the traditional operation method where the driver needs to board the crane, the main difference of the automated terminal is the use of semi-automatic or fully automatic yard loading and unloading cranes, mainly includi...

AI Technical Summary

Problems solved by technology

[0005] 1. During the lowering process of the spreader, the size of the image is constantly changing, accompanied by the severe shaking of the crane operation, which brings dazzling and discomfort to the driver, resulting in visual fatigue;

[0006] 2. When the position of the spreader is offset relative to the target container, the position of the keyhole on the image can be expressed in various forms, which brings a lot of difficulty to remote manual adjustment and takes a long time;

[0007] 3. According to the image operation, due to the shaking characteristics of the spreader itself, the driver needs to "grasp the box" under a certain image feature based on experience (that is, the driver feels that the spreader has been aligned, and instantly lowers the spreader to align the box), so High requirements are placed on the driver's operating skills;

[0008] 4. The transmission volume of data occupied by the four images is nearly 4M bytes, which is a great burden for the remote communication system of the crane

In addition, there is no similar device at home and abroad at present, and the market prospect is broad.
