Research on Distributed Access Technology of Terrain Environment Information
Aiming at the problems of large amount of data,multiple concurrent accesses and dynamic data synchronization in the simulation of force confrontation environment,based on the RPC(Remote Procedure Call)framework,a distributed access service for terrain environment that can support the distribution and synchronization of environmental information of multiple force entities is designed.According to the characteristics of different environmental data,structured and unstructured databases are combined to store multiple types of terrain data to improve data query efficiency.High-access frequency data is loaded into the memory database to improve the data acquisition efficiency of multi-force models during distributed operation.The ability of multi-armored vehicle models to obtain environmental data is tested under typical terrain,and Unity 3D is used to realize the visualization of multi-vehicle synchronous operation.Tests show that the distributed terrain environment access system realizes the functions of information distribution and multi-vehicle terrain data synchronization.This system is characterized by large amount of loadable data,high operation efficiency and reasonable operation results,and can better serve the military force simulation application system.
