实时数据分片存储模式的研究

Research about Real-time Data Sliced Storage Mode

工程控制中的实时控制系统,要求系统有很短的控制时间延迟;而在实时控制的同时,产生的实时数据的保存也会占用一定的时间;通过在实时控制系统中添加额外的存储节点,在实时控制的过程中,实时数据按时间分片,由存储节点保存到存储系统中;该模式只占用实时控制节点很少的控制时间,完成对实时数据的存储,这样在控制过程中也可以实时的读取、分析数据。

The real--time control system is a kind of engineering control system which has a very short control time delay. While execu- ting real--time control, the preservation of real--time data will take some time. To add an extra archive node to the real--time control sys- tem in the process of real time control, real time data will he sliced by time and arehived to the storage system by the archive node. This mode only need to take up real--time node little control cycle time to complete real--time data storage, and can read and analyze data in real time control process.
