Abstract:
1. A hook attitude detecting device, comprising: an angle measuring instrument configured to obtain an angle between a coordinate axis of a second coordinate system and a corresponding coordinate axis of a first coordinate system in real time; an acceleration measuring meter configured to obtain an acceleration of a hook in a predetermined direction in real time, there being a predetermined angle between the predetermined direction and the coordinate axis of the second coordinate system; a processor configured to establish the first coordinate system and the second coordinate system, wherein the first coordinate system is fixed relative to a predetermined position and the second coordinate system is fixed relative to the hook, the coordinate axis of the first coordinate system corresponds to the coordinate axis of the second coordinate system; and attitude parameters of the hook in the first coordinate system are obtained from the angle obtained by the angle measuring instrument and the acceleration obtained by the acceleration measuring meter; and an output device configured to output the attitude parameters.
