在工業控制嵌入式實時系統中應用的數據庫要同時滿足嵌入式和實時性兩方面的要
求。工業控制系統中的嵌入式實時數據庫通常作為軟件部件鑲嵌于設備中或實時應用環境中,它往往是同具體的物理設備聯系在一起的,用于保存和記錄外部設備的狀態值。本文將結合工業控制的應用背景,來分析和研究工控應用系統中嵌入式數據庫的實時性問題。并通過一個工業控制的實例分析了嵌入式實時數據庫在控制系統中的工作機制。
關鍵詞: 實時性, 嵌入式數據庫, 工控系統

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.
