The invention provides a lifting tool posture detection system and method, and relates to the technical field of hoisting. The lifting tool posture detection system comprises a master controller, a first scanning device, a second scanning device, a first reference plate and a second reference plate; the first scanning device scans the first reference plate and at least obtains a displacement vector of two target points; the second scanning device scans the second reference plate and obtains a displacement vector of at least two target points; and the master controller, according to the displacement vector of the two target points of the first reference plate, the displacement vector of the two target points of the second reference plate, coordinates of three coordinate points on the firstreference plate in a lifting tool platform coordinate system, and coordinates of three coordinate points on the second reference plate in the lifting tool platform coordinate system, generates a rotating vector of a lifting tool platform, then calculates a multiplication cross of a real-time posture change vector of a trolley platform and the rotating vector, and generates a posture change vectorof the lifting tool platform. The lifting tool posture detection system and method can improve the posture acquisition precision of the lifting tool platform.
Description
technical field [0001] The invention relates to the technical field of hoisting, in particular to a system and method for detecting the attitude of a hoisting gear. Background technique [0002] At present, when unloading containers in the automated yard of the container terminal, the main solution to prevent container collisions is to use laser scanners for distance measurement or image recognition. The scheme of using laser scanner for distance measurement is more reliable for collision avoidance, but it is difficult to obtain accurate attitude changes of the spreader in real time. Contents of the invention [0003] The purpose of the present invention is to provide a spreader attitude detection system and method, which can improve the attitude acquisition accuracy of the spreader platform. [0004] In order to achieve the above object, the technical solution adopted in the embodiment of the present invention is as follows: [0005] In the first aspect, the embodiment ...
