SCADA 系統(tǒng)作為一體化的工業(yè)自動控制系統(tǒng)，不僅要完成實時采集數(shù)據(jù)和遠(yuǎn)程
控制等基本功能，而且其自身的穩(wěn)定性和健壯性需要給予特別考慮。本文在介紹了
SCADA 系統(tǒng)軟件基本結(jié)構(gòu)后，重點討論了冗余模式下實時數(shù)據(jù)和歷史數(shù)據(jù)的同步問題，并給出了一種實現(xiàn)模型。

[Abstract] A SCADA system, which always used in different crucial operation situation,
is a hierarchical integrated system that consists of hardware and software providing
remote control and monitoring of a process or an operation, so it is necessary that think
better of the robust and reliability of SCADA. After introduced its software architecture, the
paper discussed the real-time data and historical data synchronization under the
redundant SCADA system and gave a realization model.
