摘要
为解决工业生产中的自动化控制问题,对实时数据库进行了研究。实时数据库中的调度系统采用静态表驱动为主、其他动态调度策略为辅的调度方案,分别通过该动态链接库提供的接口函数来实现对实时数据库的读写、查询和管理等功能。结果表明,该实时数据库能够很好地完成对工业过程的控制和管理,在工业组态软件系统中具有广泛的应用。
To solve the automatic control problems in industrial processes, the real-time database is researched. The scheduling system in realtime database is implemented mainly with static table driven scheduling, and other dynamic scheduling strategies as assistance. Through the interface functions provided by the dynamic linkage library, the functions of read/write, query and management for the real time database are realized. The results prove that by using the real time database, the industrial process can be well controlled and managed; and the database can be widely applied in industrial configuration software systems.
