Automatic detecting and calibrating system and method for container crane

Abstract

The invention discloses an automatic detecting and calibrating system and method for a container crane. The system comprises a rail hoisting trolley and a sling connected to the portion below the rail hoisting trolley and further comprises a calibrating device, target detecting devices and a sling detecting device. The sling detecting device is arranged at the connecting position of the rail hoisting trolley and the sling. The two target detecting devices are connected to the portion below the rail hoisting trolley and correspondingly arranged on the two sides of the rail hoisting trolley. The calibrating device is composed of six identification blocks, wherein the four identification blocks form a rectangle and are consistent in height, and the other two identification blocks are arranged on the outer side and are consistent in height but higher than the four identification blocks. Each identification block is composed of an active identification block and a passive identification block, wherein the active identification block is used for calibration of the sling detecting device, and the passive identification block is used for calibration of the corresponding target detecting devices. By means of the calibrating device, space coordinate systems of the sling detecting device and the target detecting devices can be conveniently and rapidly converted into the same reference coordinate system.

Description

technical field [0001] The invention relates to a system and method for automatic detection and calibration of cranes, more specifically, to an automatic detection and calibration system and method for container cranes. Background technique [0002] In each port, a large number of containers need to be unloaded, transferred to a temporary storage yard, and then loaded onto various forms of transportation. The loading and unloading process requires a lot of time and labor costs. Fully automated terminals can not only improve production efficiency and reduce labor costs, but also improve the working environment of workers, reduce labor intensity, and improve the comprehensive competitiveness of ports. Therefore, the construction of fully automated terminals has become an inevitable trend in the development of many container terminals at home and abroad. [0003] Fully automated terminal equipment mainly includes quayside container cranes (QC), rail container gantry cranes (RMG...

AI Technical Summary

Problems solved by technology

[0007] 2. The calibration process is relatively cumbersome and requires professionals to operate. The calibration results vary from person to person, and the calibration accuracy of different personnel is different.

[0008] 3. Long calibration time

[0009] 4. Each calibration can only control the calibration accuracy of one crane, and the calibration accuracy of other cranes cannot be accurately controlled. When the two cranes are stacked and grabbed each other, the errors will be different.
