舰艇编队作战视景仿真系统研究

Development of Ship Formation Operational Visual Simulation System

针对现代舰艇编队作战视景仿真系统的复杂性和易变性,运用基于增量模型的三维实体建模方法建立了三维实体模型库;应用XML语言进行编队配置文件的数据管理,完成了不同想定下仿真实体及其调度关系的重组;采用内存映射机制和共享内存技术,设计实现了通用的视景数据接口;建立了各种非视觉物理量的可视化模型。仿真结果证明视景系统满足实时性和逼真性的要求,在武器装备作战视景仿真领域具有工程应用价值。

Considering the complexity and changeability of the ship formation operational visual simulation system, the following techniques were introduced. Increment model was put forward to build 3D models. Based on the formation configure file, XML was proposed as a standard in data management which accomplished the recombination of the simulation entity and its attemper relation in different assumes. Aiming at the desire of large dataflow, quick exchange for visual simulation and the different communication protocols in the system, the memory mapping mechanism and virtual shared memory were applied in program, and a visual data interface design method which can adapt various data communications was presented. The visible models of all sort of invisible physical quantities were built. The system meets the need of real time and reality and can be applied in the development of weapon equipment visual simulation system.
