Embodiment 1

[0034] like Figure 1 to Figure 2 As shown, the present embodiment provides a method for controlling the motion of a stage three-dimensional dynamic ring system. The dynamic ring system includes at least one group of dynamic rings, and each group of dynamic rings includes six LED rings with different diameters. The LED ring is provided with at least three hanging points, and each hanging point is connected to a different hoist via a cable, and each hoist is connected to a retractor; the control method includes the following steps,

[0035] S1, input the ideal performance track file;

[0036] S2. Respectively acquire the spatial position coordinates of each hanging point on each LED ring and the spatial position coordinates of the hoist corresponding thereto;

[0037] S3. Obtain the length of the corresponding cable according to the position coordinates of each lifting point and the spatial position coordinates of the corresponding hoist;

[0038] S4, according to the length ...

Embodiment 2

[0057] In this embodiment, the transformation form between two LED rings in the same group of dynamic rings at any time is taken as an example to illustrate, as image 3 As shown, the solid line ring and the dotted line ring are respectively the first LED ring and the second LED ring, and the spatial position coordinates of each hanging point on the second LED ring are a1 (xa1, ya1, za1), b1 (xb1, yb1, zb1), c1 (xc1, yc1, zc1); the spatial position coordinates of the hoist connected to each hanging point on the second LED ring are A1 (xA1, yA1, zA1), B1 (xB1, yB1, zB1), C1(xC1, yC1, zC1), then the length of the cables connecting each lifting point and the corresponding hoist is obtained as follows,

[0058]

[0059]

[0060]

[0061] In this example, under the constraints, it is known that Therefore, the expression of the length of the cable at any time obtained after the length of each cable is constrained and deformed by the constraints is as follows,

[0062] ...

Embodiment 3

[0081] In this embodiment, when the heights of the three hanging points on the same LED ring are at equal coordinates, that is, in the sense of mathematical figures, the height coordinate point value of A=the height coordinate point value of B=the height coordinate point number of C value, that is,

[0082]

[0083]

[0084] Assuming that the fixed height between two adjacent LED rings in the same group of dynamic rings is H, the second LED ring is represented by the first LED ring as That is to say

[0085]

[0086]

[0087] Then the expressions of the other LED rings in the same group of dynamic rings are respectively,

[0088]

[0089]

[0090]

[0091]

[0092] After increasing the fixed height to obtain the horizontal position of other LED rings, you can control 6 LEDF rings at the same time to achieve the demonstration effect of rising and falling at the same time.

[0093] By adopting the above-mentioned technical scheme disclosed by the prese...

Abstract

The invention discloses a method for controlling the movement of a three-dimensional dynamic ring system of a stage. The control method comprises the following steps of: step 1. inputting an ideal performance trajectory file; step 2. obtaining the space position coordinates of each hanging point on each LED (Light Emitting Diode) circular ring and the space position coordinates of a hoister corresponding to each hanging point; step 3. obtaining the length of a corresponding cable according to the position coordinates of each hanging point and the space position coordinates of the hoister corresponding to the hanging point; step 4. obtaining the speed of each cable when the cable is deployed and retracted according to the length of each cable; and step 5. running each LED circular ring to the space coordinates being the same as that of the ideal performance track file according to the space position coordinates of each hanging point, the space position coordinates of each hoister, the length of each rope and the speed of the rope when the rope is deployed and retracted. The method has the advantage of providing relatively attractive modeling setting for a multi-layer dynamic ring byplanning the length between each LED circular ring and the rope and the relationship between speed and time in advance.

Description

technical field [0001] The invention relates to the technical field of stage performances, in particular to a method for controlling the motion of a stage three-dimensional dynamic ring system. Background technique [0002] At present, the audience's demand for stage visual aesthetic effects is increasing day by day, and the development of new media technology has promoted the transformation and development of stage visual effects into a major reform trend.
