Engineering machine and working space dynamic anti-collision method, device and system thereof

Abstract

The invention discloses an engineering machine and a working space dynamic anti-collision method, device and system of the engineering machine. The working space dynamic anti-collision method comprises the following steps: receiving obstacle information around a boom of the engineering machine and boom movement information of the engineering machine; determining an obstacle coordinate according tothe obstacle information and the boom movement information; judging whether the obstacle coordinate is located in a predetermined early warning area or not; instructing an executing device to issue collision warning information outward in the case that the obstacle coordinate is located in the predetermined early warning area. The engineering machine and the working space dynamic anti-collision method, device and system of the engineering machine disclosed by the invention can detect surrounding obstacle situations during the movement process of the engineering mechanical boom in an all-weather and real-time manner, to perceive dynamic information of a lifting space, so that anti-collision warning can be controlled to ensure the safety of the engineering machine during the lifting operation process and reduce the work intensity of an operator.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a dynamic anti-collision method, device and system for construction machinery and its working space. Background technique [0002] Cranes are the most important construction machinery for hoisting operations, but their operating environments are complex and changeable, and their accident rate is high. The main cause of the accident is the collision caused by the overload of the hoist and the limitation of the working field of view. Contents of the invention [0003] The applicant found that: in order to prevent collisions during the hoisting operation, the related technology adopts a path planning solution before hoisting. [0004] The path planning before hoisting is to use the crane as a multi-degree-of-freedom manipulator, establish its kinematics and dynamics model, and calculate its anti-collision path through an optimal anti-collision algorithm in its configurable s...
