Abstract

The invention provides a cantilever crane control system which comprises a height detection unit, a judgment unit and a control unit, wherein the height detection unit is used for detecting the height information of a cantilever crane in real time and obtaining the height of the highest position according to the height information, the judgment unit is used for judging the motion trend of the cantilever crane according to the height of the highest position, and the control unit is used for controlling the motion of the cantilever crane according to the height of the highest position, the motion trend and the preset height threshold value. The invention also provides a concrete pump truck and a cantilever crane control method. In the technical scheme, the operating mode of the cantilever crane can be rapidly shifted according to the different use environments, the operation is simple, and the collision during the operation of the cantilever crane can be effectively prevented through the intelligent control so as to enhance the operating efficiency.

Description

technical field [0001] The invention relates to the technical field of boom control, in particular to a boom control system, a boom control method and a concrete pump truck. Background technique [0002] At present, ultra-low deployment height pump trucks are widely used in indoor, tunnel, roadway and other places. Due to the limited space height, the boom of the pump truck cannot be fully extended like outdoors. In order to ensure the smooth deployment of the boom without collision, the minimum deployment height of each section of the boom is required to be less than the total height of the room. This unfolding mode is very different from the mode of freely unfolding outdoors. [0003] Therefore, it is an urgent problem to propose a new boom control technology to avoid the collision between the boom and the objects above the work space when the height is limited. Contents of the invention [0004] One aspect of the present invention is to propose a new boom control sys...
