Projection sand table capable of automatically constructing terrain and projection system

Abstract

The invention relates to a projection sand table capable of automatically constructing a terrain and a projection system, wherein the projection sand table comprises a frame, a sand table lifting assembly, a left-right mounting assembly and a plurality of sand pushing units, wherein the middle part of the frame is provided with an installation space with an upward opening; the sand table lifting assembly comprises a lifting mechanism and a sand containing table, the lifting mechanism is arranged on the frame, the sand containing table is arranged in a mounting space in the vertical direction,and the lifting end of the lifting mechanism is detachably connected with the sand containing table to drive the sand containing table to move in the vertical direction; the left-right mounting assembly comprises a mounting table and a left-right driving mechanism, and the power output end of the left-right driving mechanism is detachably connected with the mounting table to drive the mounting table to move left and right above the sand containing table; and the plurality of sand pushing units are arranged on the mounting table along the front-back direction, each sand pushing unit comprises asand pushing rod and a sand pushing driving mechanism, and the sand pushing driving mechanism is used for driving the sand pushing rods to be close to the sand containing table downwards or to be faraway from the sand containing table upwards. The technical scheme of the invention solves the problems that in the existing three-dimensional electronic sand table, the topography and the landform ofthe sand table cannot be visually observed by a user.

Description

technical field [0001] The invention relates to the field of combat command equipment, in particular to a projection sand table and a projection system for automatically constructing terrain. Background technique [0002] As an auxiliary tool for combat research, sand tables have always been valued by army commanders and staff officers. In the period of underdeveloped computer technology, people mainly made physical sand tables by means of physical accumulation to meet the needs of combat research. With the rapid changes in the information battlefield , the traditional physical sand table and marking methods can no longer meet the needs of future combat research. With the rapid development of computer technology, there have been products that display three-dimensional electronic sand tables through the screen. It can quickly and accurately display two-dimensional and three-dimensional maps and realize linkage. Because the existing electronic sand table is displayed through a...
