The Research On Weaponry Photoelectric Simulation Database

Weaponry photoelectric simulation system is composed of the infrared object and scene generated subsystem, exploring and tracking simulation subsystem, movement simulation platform, simulation analysis evaluation subsystem and simulation control with visual display subsystem. All the subsystems are linked together by a computer network, and the simulation databases are required to support their running. For the process of simulation, the databases are supposed to be provided with two sides: real-time access for the distributed memory data and intelligence simulation technology. Because each site in this simulation database emulates the different position and function structure character, and comes down to multi-platform, multi-type data, the great amount of system parameters, models, model structure parameters and rules in simulation must be managed by distributed database for administration, rapid information query and dynamic storage modification. In the course of the practicality, the professional knowledge and experiences, or the capability of nonlinear function approximation are adopted in fuzzy modeling, then genetic arithmetic is applied to optimize the network. The technology, illation rule and parameter of neural network are supposed to be held in database and make a delicate database system. During the development, the structure and function of the system are consummates by the build of system model, function model and data model. In addition, it adopts DIS (Distributed Interactive Simulation) and the "top-down work downward" constructive design method to prooftest, modify and perfect the process and date flow, including the integrality, rationality, practicality and reliability of the system. Consequently, we build a more practical and rational database system, and meet the needs of the simulation.
