摘要
分析了海洋大气环境的数据特征,以及在实时仿真中面临的多分辨率和海量数据实时调度两个核心难题。提出了一种分离式表示模型用来解决多分辨率表示问题,并基于BerkeleyDB的持久化和缓存技术,设计了一种可行的海量复杂海洋大气环境数据的存储方法及数据在内存和磁盘之间的实时调度策略。仿真实例验证上述方案为一种有效解决方法。
The data feature of ocean and atmosphere environmental (OAE) and multi-resolution and real time displacement problem countered by real-time simulation applications. Secondly, a separated representation model is proposed to solve multi-resolution problem were analyzed. Then, the storage of OAE data and its real time displacing between memory and disk was solved based on Berkeley DB’s persistence and cache method. Finally, above solutions were verified by some experiment data through practical simulation cases.
