AI Technical Summary

Technical Problem

In existing technologies, relying solely on geometric distance for judgment is prone to misjudgment when point cloud data is disturbed, resulting in low accuracy in container anti-hook control.

Method used

Millimeter-wave radar is introduced as the basis for distance perception. The second distance is calculated by combining the boom length and angle. The control logic is supplemented by visual condition recognition and spreader weight for multiple verifications. The first distance is collected by millimeter-wave radar, the reference weight is obtained, the second distance is calculated, and the container is determined to be separated from the object being detached by combining multiple criteria. The boom is then controlled to stop lifting.

Benefits of technology

Without significantly sacrificing the real-time performance of measurements, the perception reliability and judgment accuracy of container anti-hook control have been improved, reducing the risk of misjudgment and missed judgment.

Abstract

The application provides a container anti-hanging box control method, device and equipment and a readable storage medium, comprising: collecting a first distance by the millimeter wave radar when the crane is in a preset working condition, the first distance being the distance between the container and the separated object; obtaining the reference weight of the container based on the first distance; calculating a second distance according to the boom length and the boom angle; determining whether the container leaves the separated object according to the first distance, the reference weight and the second distance, and controlling the boom to stop lifting when it is determined that the container does not leave the separated object. On the basis of not significantly sacrificing the measurement real-time, the sensing reliability is effectively improved, thereby improving the accuracy of determining the existence of the hanging box risk.
