A dynamic screen system and its control method

Abstract

The invention relates to a dynamic screen system. The dynamic screen system comprises a motion control system and a plurality of mechanical execution mechanisms. The motion control system comprises a control information issuing layer and an information transmission layer which are sequentially connected. The information transmission layer comprises a master switch, a field switch and at least two CAN communication servers, wherein the master switch, the field switch and the CAN communication servers are sequentially connected. Electric cylinders are adopted as the mechanical execution mechanisms, wherein covers with screen coatings are installed on push rods of the electric cylinders. When the push rods are in a zero position, the tops of all the covers are located on the same plane, and tessellation is achieved; the master switch is connected with the control information issuing layer. The CAN communication servers are connected with the electric cylinders sequentially through motor controllers and motor drivers. Motion commands issued by the control information issuing layer and transmitted through the information transmission layer are executed by the electric cylinders. A control method of the dynamic screen system includes initializing a central processing unit, reading position marks of the dynamic screen system, judging whether commands and data need receiving or not, checking the current working state, carrying out command processing steps and switching to an instruction waiting state.

Description

technical field [0001] The invention relates to a screen system, in particular to a dynamic screen system and a control method thereof. Background technique [0002] Static screens are more popular in daily life. For example, monitors and electronic screens used in daily life are all static screens. Although with the continuous development of 3D technology, static screens can show a three-dimensional effect to a certain extent, but they are still Plane images receive different images through the left and right eyes, and the three-dimensional effect produced by the chorus of the brain is not ideal, and it is very limited, and cannot achieve the naked-eye 3D effect; the existing 3D projection shows The three-dimensional effect also lacks a sense of reality, and it can or cannot be applied to the presentation of the three-dimensional effect in a large scene. Contents of the invention [0003] The purpose of the present invention is to provide a dynamic screen system and its ...
