| Abstract: | This paper introduces the necessity of research on RTDBS of supervisory control and data acquisition configuration software (SCADACS), including the function and characteristic of general RTDBS. By analyzing the unique function and characteristic of RTDBS of SCADACS , presents a system framework of RTDBS of SCADACS . Then discusses main parts of this framework such as Configuration Database , Event Library ,PRI Library, Transaction Schedule, the mechanism of buffer of historical data, Active Mechanism , Main Memory Database,Real-time run-time system ,and presents the implementation module for reference. Finally the performance of RTDBS on experiment is given. |
