工控应用系统中嵌入式数据库实时性研究

在工业控制嵌入式实时系统中应用的数据库要同时满足嵌入式和实时性两方面的要求。工业控制系统中的嵌入式实时数据库通常作为软件部件镶嵌于设备中或实时应用环境中,它往往是同具体的物理设备联系在一起的,用于保存和记录外部设备的状态值。本文将结合工业控制的应用背景,来分析和研究工控应用系统中嵌入式数据库的实时性问题。并通过一个工业控制的实例分析了嵌入式实时数据库在控制系统中的工作机制。

The Real-Time Research of Embedded Data一Base in Industrial Control System

The database that applied in the industrial control embedded real- time systems need to meet embedded and real- time re- quirements. The database that applied in the industrial control embedded real- time systems usually acts as software components em- bedded in the equipment or real- time application environment. So it is as often associated with the specific physical equipment to save and record the state value of the external equipment. In this paper, I analyze and study the problem of real- time of the database that applied in the industrial control embedded real- time systems in the background of the industrial control application. And analyze the work mechanism of the embedded and real- time database in the control system through an example of industrial control.
