Abstract: In view of the problem that military simulation training system can't maximize to the advantages of virtual reality simulation technology because of the limitations of regional, space and training ability, this paper developed a virtual equipment training and teaching platform. It made a large-scale compression for 3D models and map data. Meanwhile it made streaming and multithreading download of compressed data through the HTTP protocol. It dealt with the high concurrent access on network by using the balanced load. So that it has broken the limitations of regions space and training ability of the previous military simulation training system, and improved the use value of the virtual reality simulation technology in teaching of military training.
