| Abstract: | 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. |
