工控應(yīng)用系統(tǒng)中嵌入式數(shù)據(jù)庫實時性研究

在工業(yè)控制嵌入式實時系統(tǒng)中應(yīng)用的數(shù)據(jù)庫要同時滿足嵌入式和實時性兩方面的要
求。工業(yè)控制系統(tǒng)中的嵌入式實時數(shù)據(jù)庫通常作為軟件部件鑲嵌于設(shè)備中或?qū)崟r應(yīng)用環(huán)境中,它往往是同具體的物理設(shè)備聯(lián)系在一起的,用于保存和記錄外部設(shè)備的狀態(tài)值。本文將結(jié)合工業(yè)控制的應(yīng)用背景,來分析和研究工控應(yīng)用系統(tǒng)中嵌入式數(shù)據(jù)庫的實時性問題。并通過一個工業(yè)控制的實例分析了嵌入式實時數(shù)據(jù)庫在控制系統(tǒng)中的工作機制。

Abstract: The database that applied in the industrial control embedded real-time systems need to meet embedded and real-time requirements. The database that applied in the industrial control embedded real-time systems usually acts as software components embedded 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.
