为了提高半实物仿真系统数据管理水平,简化数据库操作的复杂度,文中提出了在仿真系统中使用轻量级数据库系统SQLite的方案。并针对半实物仿真系统中硬实时性要求的特点,提出了5点SQLite性能优化策略,有效的提高了操作SQLite数据库的访问速度。通过测试及实验验证表明,SQLite能够满足半实物仿真实验对数据实时存储及数据持久保存与管理的需求。

In order to improve data management of the hardware in loop simulation system, and simplify the complexity in database operation, the application of SQLite database in the simulation system was introduced. According to the hard real time requirement, 5 optimization principles were proposed to improve the SQLite's performance. The test and experiment show that the SQLite database could be a good substitute for commercial DBMS, and can meet the simulation system's data storage and management requirement.
