Stage table top controllable platform

Abstract

The invention relates to a stage board controllable platform, which comprises an up-and-down movable board which is arranged on the stage for laying out the stage; an accurate positioning mechanism, which comprises a worm, an accurate rotating device, a worm wheel, a screw rod and a traction rope, wherein the accurate rotating device drives the worm, the worm wheel is horizontally arranged for matching with the worm, the screw rod penetrates through the center of the worm wheel and is longitudinally arranged, the center of the worm wheel is provided with a threaded hole, the worm wheel is in threaded connection with the screw rod, the traction rope is connected at the top of the screw rod, and is used for pulling the up-and-down movable board to move up and down, the accurate rotating device drives the worm according to a received position deviation value so as to drive the traction rope to pull the up-and-down movable table board to move up and down. According to the invention, the positioning accuracy of the up-and-down movable board can be improved.

Description

technical field [0001] The invention relates to the field of stage equipment, in particular to a controllable stage platform. Background technique [0002] The stage table is mostly paved with dance floor glue or dance beauty floor glue board. It is a soft polyvinyl chloride. It is professionally formulated according to the characteristics of dance. It has a certain buffering effect, not astringent, not slippery, and flexible nice feature. The general PVC is mostly used in industrial insulation materials, and the material is hard and rough. The other is sports ground rubber, which is suitable for sports competitions and so on. It is qualitatively different from the special glue for dancing. The color of the dance floor is multi-colored, and it can be made according to the color card provided by the customer. At present, the main colors used by dance groups are: dark green, lake blue, sky blue, light gray and so on. The specifications of dance floor glue are divided acco...

Problems solved by technology

[0003] In order to solve the technical problem that the upper and lower positions of the up and down movable table are difficult to adjust adaptively, the present invention provides a controllable platform for the stage table, which is realized based on the deviation between the real-time height position and the preset height position of the up and down movable table by using precise rotating equipment The precise adjustment of the up and down position of the up and down movable table solves the technical problem of inaccurate positioning of the up and down movable table caused by the long-term use of the traction rope; based on the blurred degree of the image, the corresponding size of the imaging image is uniformly divided Block processing, for each image block, adjust its threshold based on the threshold of its neighborhood image blocks, thereby improving the accuracy of image binarization; adjust the light-emitting mode of the flashlight near the image capture device based on the detection of ambient brightness, and Determine the corresponding degree of blur based on the output content of the image capture device, and remind the user to make corresponding adjustments when the blur is too much
