摘　　要：基于IP模式测控系统的实时性分析,提出系统数据库的实时工作流程,研究分析分级处理的硬件构造、多线程机制及内存资源优化等问题。重点研究文件关联、内存资源回收等关键技术,并采用C++实现。基于等价实验方法,结果表明,数据库的延迟小,实时性好,方案可行。According to analysis on the real-time of IP mode measurement and control system, the real-time working process of database in the system is brought forward and some new schemes are mainly discussed, including hardware constitution based on stage treatment, the multithreading mechanism and resource optimization for the EMS memory. Furthermore, some key technologies are especially studied, such as file relevancy and recovery of the EMS memory resource, which are all realized by C ＋＋. Through the equivalent experimental method, the results show that the database possesses little delay and satisfying real-time and the schemes are feasible.
