AI Technical Summary

Technical Problem

Existing collision avoidance warning systems for machinery use alarm zones of fixed shapes, which cannot adapt to changes in the posture of the machinery's working devices. This results in blind spots and excessive alarms, reducing the accuracy of the warnings and the reliability of the system.

Method used

By acquiring real-time attitude data of the operating machinery, an envelope warning area that is equidistant from its contour is dynamically generated. The system monitors whether there are obstacles within the envelope warning area and triggers a warning response when an obstacle is detected.

Benefits of technology

It achieves real-time alignment between the warning area and the actual working contour of the machinery, eliminates blind spots in the warning, avoids excessive alarms for static obstacles, and improves the accuracy of the warning and the reliability of the system.

Abstract

This application discloses a method, controller, and working machinery for collision avoidance warning. The method includes: acquiring real-time attitude data of the entire machine during operation; determining the real-time outline of the working machinery in its current attitude based on the real-time attitude data and pre-stored structural data of the working machinery; determining an envelope warning area of ​​the working machinery in its current attitude based on the real-time outline and a preset safety distance, wherein the shortest distance from any point on the boundary of the envelope warning area to the real-time outline is equal to the preset safety distance; monitoring whether there are obstacles within the envelope warning area, and triggering a warning response when an obstacle is detected. The real-time alignment of the envelope warning area with the actual working outline of the machinery in this application eliminates warning blind spots while avoiding excessive alarms for static obstacles, thus improving the accuracy and reliability of the warning system.
