Embodiment Construction
[0058] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.
[0059] The invention provides a method for controlling the posture of a three-lifting point performance disc, which is used for the posture control of the hanging plate in the stage equipment industry. The technology controls the posture of the disc by changing the rope length of the three-lifting point to meet the stage scene layout and performance activities. Demand. The main idea is: firstly, establish the three-dimensional space coordinate system of the disc, and match the lifting point coordinates and fixed point coordinates of the lifting point; then set the coordin...

The invention provides an attitude control method for a three-hanging-point performance disc. The attitude control method comprises the steps of: establishing a disc space coordinate system; matchingcoordinates of each hanging point and a fixed point in a three-dimensional coordinate system; determining a rotating axis and a tilting axis on the surface of the performance disc in a horizontal attitude; determining initial coordinates of the lowest point in a tilting attitude; determining a distance from a circle center of the disc to the rotating axis; determining a tilt angle; determining coordinates of an intersection point of the rotating axis and the tilting axis, a vector of the rotating axis and a vector of the tilting axis; calculating coordinates of the hanging points after changing the attitude; and calculating a rope variable quantity corresponding to each hanging point separately, so that a corresponding motor performs rope expansion and contraction operations, thereby making the hanging disc rotate around the rotating axis, and further controlling the variation of the attitude of the hanging disc. The attitude control method for the three-hanging-point performance discprovided by the invention has the advantages of high hanging disc attitude control precision, simple implementation process, high control flexibility and wide application range.
Description
Technical field [0001] The invention belongs to the technical field of control systems, and specifically relates to a method for controlling the attitude of a three-pointed performance disc. Background technique [0002] Hanging pans are commonly used stage equipment in stage scenery. For example, a circle of lights is installed on the hanging pans, and by controlling the attitude of the hanging pans, the light irradiation direction can be controlled to achieve the stage lighting effect. In the prior art, the manual control method is mainly used for the attitude control of the suspension plate, which has the problems of low accuracy of the attitude control of the suspension plate and poor control effect. Summary of the invention [0003] In view of the defects in the prior art, the present invention provides a three-point performance disc posture control method, which can effectively solve the above problems. [0004] The technical scheme adopted by the present invention is as foll...
