Intelligent sand table based on magnetorheological cement

Abstract

The invention relates to an intelligent sand table based on magneto-rheological plaster. The intelligent sand table based on magneto-rheological plaster comprises a base and a tray, wherein a plurality of magnetic field generating devices are arranged between the base and tray and distributed in a matrix mode to form a m-row n-column magnetic field generating device array, the magneto-rheological plaster is filled in the tray, the surface of the magneto-rheological plaster is kept horizontal when being not subjected to the magnetic field effect, the magnetic field generating devices are respectively connected with power supply modules corresponding in a one-to-one mode through lead wires, the power supply modules are respectively and electrically connected with a programmable current controller, the programmable current controller is used for respectively outputting control signals to the power supply module according to preset procedures, controlling the power supply modules respectively outputting exciting current to the corresponding magnetic field generating devices, the magnetic field distribution of a whole magnetic field generating device array region and surface appearance of the magneto-rheological plaster and forming the sand table. The intelligent sand table based on the magneto-rheological plaster has reversibility, can be repeatedly used and further has the advantages of being quickly established and dismantled.

Description

technical field [0001] The invention relates to a sand table, in particular to an intelligent sand table based on magnetorheological cement. Background technique [0002] The sand table is a model made of sand, war chess and other materials in a certain proportion according to the topographic map, aerial photo or field terrain. Sand tables are widely used in military operations, terrain surveys, and other fields. They can vividly display the topography of the combat area, and indicate the composition of the enemy's and our positions, the deployment of troops, and the configuration of weapons. Military commanders often use it to study terrain, enemy situations, and combat plans, organize coordinated actions, implement tactical drills, study battle cases, and summarize combat experience. The existing sand table can only simulate one piece of terrain. If you want to obtain information about other topography and landforms, you must make another sand table, which has problems su...

AI Technical Summary

Problems solved by technology

The existing sand table can only simulate one piece of terrain. If you want to obtain information on other topography and landforms, you must make another sand table, which has problems such as non-reusable, difficult to make, and low production efficiency.
