Three-dimensional map sand table device as well as control system and method for same

Abstract

The invention discloses a three-dimensional map sand table device as well as a control system and a control method for the three-dimensional map sand table device. The system comprises a plurality oflifting strip blocks capable of realizing rise and fall which are arranged in a table rack and are in net array distribution, the lifting strip blocks comprise pneumatic lifting columns, hollow air cylinder cavities downwards extending and provided with openings are arranged inside the pneumatic lifting columns, hollow fixing rods are movably arranged in the hollow air cylinder cavities through piston plates mounted at the top ends, the peripheries of the piston plates are in sealed contact with the inner walls of the hollow air cylinder cavities, air holes communicating to the hollow fixing rods are arranged at the tops of the piston plates, air cocks are mounted on the bottoms of the hollow fixing rods, the air cocks are connected with an electric air pump through an air inlet accurate control device, and the air inlet accurate control device is connected to a controller. Due to the adoption of the lifting principle of the pneumatic structure, the technical scheme has the advantagesthat the lifting operation is convenient and rapid, the integral structure adopts lightweight design, and the rise and fall as well as hovering control facilitates maintenance, the cost of consumableitems of the device is greatly reduced, in addition, the high-pixel sand table structure can display the three-dimensional topography in a more refined manner and with high completion degree, and canbe assembled into the specific shape, the combination degree is high, and the practicability is good.

Description

technical field [0001] The invention relates to the technical field of electronic map sand table, in particular to a three-dimensional map sand table device and its control system and method. Background technique [0002] The sand table is a model showing terrain and ground targets made with sand or other materials and wargames on a scale based on topographic maps, aerial photos, and on-the-spot terrain. It has the characteristics of strong three-dimensional sense and intuitive image. The sand table is widely used, it can visually display the terrain of the combat area. In the peaceful age, the sand table is also often used to make models of economic development planning and large-scale engineering construction. Its image is intuitive and is favored by planning decision makers and engineering technicians . In recent years, the simulation demonstration of disaster-stricken areas on the CCTV news channel is a case of sand table application in the prevention and control of na...

However, the existing three-dimensional models and sand tables are fixed and unchanging exhibits, which can only be changed by the cooperation of lights. Although the appearance of this device is realistic and easy for visitors to understand, its form of expression Rigid, unable to interact with the audience, the performance content is single, so that visitors cannot obtain the content they are interested in through the sand table or three-dimensional model, and cannot add some content that can introduce the details of the sand table or three-dimensional model in a deeper level, and the display content cannot be based on The display theme is changed, which greatly reduces its due display effect and cannot meet the needs of current visitors who focus on visiting experience

[0005] Chinese invention patent CN201310431624.4 An electronic sand table system and method provides an electronically controlled technology for automatically forming a three-dimensional sand table, but the cost required for this technology is extremely high, and a lifting motor needs to be configured under each lifting column. Coupled with image lighting control, the overall cost is quite high, and it is not practical for actual production and use.
