Design and Research of Distributed Real TimeSurveillance Control System

摘要

Distributed real time surveillance control system is used especially in distributed computer measure and control system, mostly inwidely dispersed measure points without human surveillance. This paper describes theory、construction、control strategy, stabilityanalysis of distributed real time supervisory control and data acquisition system, implements distributed measure signals collectionand design of supervisory control system. The realization of virtual instrument based on VC＋＋ can accomplish measurementsignals acquisition, storage, display and analysis, also the result of surveillance control system is provided, and shows thefunctional powerful agility of virtual instrument based on VC＋＋.
