无人飞行器飞行实时大气环境仿真服务器

Design and Implement of Real-time Virtual Atmosphere Environment Server Based on HLA

无人飞行器飞行仿真实时大气环境服务器是大气环境仿真服务系统(Atmosphere Environment Simulation Platform)的一部分。在仿真应用中,它负责响应仿真联邦内无人飞行器以及其它实体的大气环境信息请求,并反馈以正确的环境信息。实时大气环境服务器的实时性是保证整个仿真系统正常运行的重要环节。介绍了实时大气环境服务器的设计方案,引入内存数据库技术,提出磁盘与内存交换策略来解决实时大气环境服务器的实时性的问题。在实际应用中,实时大气环境服务器运行良好,满足了多用户实时的环境信息请求。

The Real-Time Atmosphere Environment Simulation Server（RTAES） is an important part of Atmosphere Environment Simulation Platform（AESP）.It shows a response to any entity in the federation request for atmosphere environmental information.The design of a real-time virtual atmosphere environment server was described based on High Level Architecture（HLA）.It is an efficient approach to real-time problems to use memory database and data switching Strategy.As a result,an RTAES is implemented under the direction and its application in real-time simulation certifies its outstanding performance.
