摘要
对于工业控制实时系统来说,实时数据、历史数据的I/O速度是系统的主要瓶颈。本文提出一种新的文件组织及数据池管理方式,通过利用数据缓冲池和内存索引机制对实时数据及海量历史数据进行有效管理,不仅加快实时数据的读/取速度,而且提高系统的整体性能,在实际的应用中取得了较好效果。
For industrial control systems,the I/O speed of real-time and historical data has always been the main bottle neck.This paper presents a new method for file organization and data pool management.Through the use of data pools and the memory index mechanism,effective management of real-time data and tremendous quantity of historical data is achieved.Thus,not only the reading and writing of real-time data can be speeded up,the entire performance of the real-time systems can also be improved.This method has manifested fairly good effects in applications.
