基于數(shù)據(jù)庫的模塊化遠(yuǎn)程測控系統(tǒng)的研發(fā)

本文完成了基于數(shù)據(jù)庫的模塊化遠(yuǎn)程測控系統(tǒng)的總體方案的設(shè)計，對整個系統(tǒng)進(jìn)行各
個功能模塊的劃分。采用VC 提供的MSComm 控件實現(xiàn)了現(xiàn)場設(shè)備下位機(jī)和服務(wù)器端上位機(jī)之間進(jìn)行串口通信。然后探討了數(shù)據(jù)庫技術(shù)，采用SQL Server2000 作為系統(tǒng)的數(shù)據(jù)庫，結(jié)合ADO 技術(shù)實現(xiàn)數(shù)據(jù)庫的訪問。對系統(tǒng)的實時性和安全性問題進(jìn)行了分析和研究。

Abstract: After raising the general design scheme for remote control system, the subject realize the communication between MCU and Server by adopting MSComm Control provided by Visual C. The subject divided the whole software into several functional modules, in which SQL2000 was adopted as the database for remote control system and ADO technique was applied to access to the database. Researched and analyzed the questions of the real-time character and safe character of the system.
