Document Type and Number:
WIPO Patent Application WO/2022/141458
Kind Code:
A1
Abstract:
A hoisting control method and system, and an engineering machine, relating to the field of boom engineering control technologies, and solving the problems of a too narrow automatic hoisting operation application scene range and inaccurate boom head positioning. Said method comprises: acquiring a target position of a designated hoisting operation of a boom head of a boom engineering machine, and controlling the boom head to reach a designated position at a preset speed in the process of reaching the target position, and detecting the angular velocity of rotation, the amplitude change speed, the slipping stop angle, and slipping stop amplitude range of the boom head, and controlling, according to the distance between the boom head and the target position, the angular velocity of rotation, the amplitude change speed, the slipping stop angle, and the slipping stop amplitude range, the boom head to stop at the target position. Said method and system are applicable to automatic hoisting operations of boom engineering devices.
