Dynamic physical sand table and dynamic display control method thereof

Abstract

The invention relates to the technical field of sand table display, and provides a dynamic physical sand table and a dynamic display control method thereof, and the sand table comprises a plurality of pixel modular units which are distributed in an array, and each pixel modular unit comprises a plurality of pixel columns; the plurality of pixel columns are in signal connection with the two signal gates through address signal lines, the two signal gates are connected with the first controller, and the two signal gates are connected with the first controller through height signal lines; and each pixel stand column is connected with a driving device, the driving device is connected with a second controller, and the second controller is connected with the two address signal lines corresponding to the pixel stand columns through an AND gate and used for controlling the driving devices to drive the selected pixel stand columns to ascend and descend according to preset height signals. According to the invention, the pixel modular units can be used for assembling a physical sand table with any size and high resolution, and any pixel stand column can be independently controlled to ascend and descend to be changed to a specified physical height, so that dynamic display is realized.

Description

technical field [0001] The invention relates to the technical field of sand table display, in particular to a dynamic physical sand table and a dynamic display control method thereof. Background technique [0002] The sand table is a model made of sand, war chess and other materials according to a certain proportion of topographical maps, aerial photos or on-site terrain. The sand table can intuitively display macroscopic things. At present, most of the sand tables are still statically fixed, that is, the models made at one time according to the requirements cannot be adjusted and modified. After use, they are disassembled and discarded, which wastes manpower and material resources, and the use effect is poor; some sand tables use digital sand tables, but the input cost is high. Low popularity. Contents of the invention [0003] The invention provides a dynamic physical sand table and its dynamic display control method, which can be assembled into a physical sand table of...
