新型DCS组态软件实时数据库研究和开发

The Study and Development of Real-time Database for a new type DCS Configration Software

本文基于自主研发的工业以太网和CAN总线的硬件平台上,研究并实现了一种嵌入式工业控制组态软件的实时数据库。文章展示了实时数据库的功能和结构,探讨了第三方接口,事务调度和并发控制的实现方法,针对内存设计的高效数据检索,历史数据的转化等主题。

This paper develops a new type of embedded Main Memory Real-time Database based on Industrial Ethernet and CANbus. The article illustrates the function and architecture of real-time database, It also talks about the third part interface. It explains how to realise transaction schedule and concurrent Control. Providing efficient data retrieval, restoring data records from memory to history database is also described.
