AI Technical Summary

Technical Problem

Existing methods for preventing collisions with boom-type construction machinery in narrow and complex environments are inefficient and pose high safety risks. Current technologies cannot effectively prevent collisions when obstacles are in dangerous positions.

Method used

By setting a first measuring device and a second measuring device on the boom, the coordinates of obstacles in the upper and lower areas are collected respectively. The minimum distance is determined by combining the boom coordinates, and early warning control is performed according to the preset safety threshold. This includes establishing a vehicle coordinate system, determining the minimum distance of the telescopic boom, flying boom and attachments, and adopting an early warning control strategy.

Benefits of technology

This improves the operational efficiency of boom collision avoidance methods, reduces safety risks, and decreases the likelihood of collisions between the boom and obstacles.

Abstract

The application discloses an anti-collision method of an arm support, a controller and an arm support type engineering machine. The method comprises the following steps: acquiring the coordinates of a first type of obstacles collected by a first measuring device and the coordinates of a second type of obstacles collected by a second measuring device every preset time; determining the arm support coordinates of the arm support; determining the first minimum distance between the first type of obstacles and the arm support according to the coordinates of the first type of obstacles and the arm support coordinates, and determining the second minimum distance between the second type of obstacles and the arm support according to the coordinates of the second type of obstacles and the arm support coordinates; and performing early warning control on the arm support according to the first minimum distance, the second minimum distance and a preset safety threshold. By determining the first minimum distance and the second minimum distance, and then combining the first minimum distance, the second minimum distance and the preset safety threshold to perform early warning control on the arm support, the operation efficiency of the arm support anti-collision method can be improved, and the safety risk of the arm support can be reduced.
