Abstract

The invention provides a construction machinery safety control method, which relates to the technical field of construction machinery. The construction machinery safety control method includes the following steps: adopting an angle sensor to collect the inclination angle of a moving arm frame of the construction machinery; specifying a key point on the moving arm frame, and calculating the coordinate position of the key point according to the inclination angle; establishing a moving arm according to the coordinate position of the key point The real-time outer contour of the frame; select the key point as the risk point, and calculate the risk value of the risk point according to the coordinate position of the obstacle; determine the risk value of the risk action according to the risk value of the risk point; according to the risk value of the risk action, Safely controlled motion jib. The method can control the engineering machinery in time to avoid dangerous situations.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a safety control method for engineering machinery. Background technique [0002] When there are obstacles, facilities that need to be protected or specified activity boundaries around the construction machinery, the construction machinery needs to automatically avoid or not cross the boundary automatically to ensure the safety of personnel and facilities. [0003] The existing technology is to install various types of positioning sensing devices on construction machinery, such as: laser positioning, radio positioning, GPS satellite positioning, total station positioning, image positioning and so on. Its positioning sensing system is complex and inconvenient to install and use; the working conditions are harsh and it is difficult to adapt to the harsh construction site environment; real-time communication with the controller of the construction machinery is difficult...
