实时交互仿真环境设计研究

A Design of Special Purpose Real-Time Interactive Simulation Environment

对仿真环境进行了较为深入的讨论，由国外技术及文献得到有益的启发，针对设计目标与航空应用的需求，提出实时交互仿真环境（RISE）概念，并进行了系统设计。设计中采用新的概念与思想，引入RFM、蛀孔寻径、VR和高速动态应用数据库等先进技术；同时，讨论了系统实现涉及到的关键技术，力求做到理论研究与工程实现的结合，注重技术的先进性，并考虑到工程可实现性及可靠性。

DARPA of U. S. Department of Defense develloped distributed interactthe simulation (DIS) technology. DIS is too costly for China to develop and, for our purpose, we found that it is somewhat deficient in real - time capability.There are only severai tens of nodes in our speciai -purpose reai - time interactive simulation environment (RISE) design, very few as compared with the vast number of nodes in DIS. The part of hardware of our RISE design directly responsib1e for its rea1 - time capability consists of two networks: (1) the RFM reai - time network alrendy developed and used in U. S. and other countries, (2) the wormho1e routiflg real - time local network developed by us and discussed in detail in this paper.In our design of RISE software, we utilired recent technical developments such as cooperative technology, dynamic - simulation - algorithm database, virtual reality (VR), multi media information real - time transmission, etc.
