為解決現(xiàn)有監(jiān)控系統(tǒng)結(jié)構(gòu)復(fù)雜，成本高以及維護(hù)不便等缺點(diǎn)，本文研制開發(fā)了基于
PROFIBUS 現(xiàn)場總線的通用型監(jiān)控系統(tǒng)。本監(jiān)控儀表包括監(jiān)控儀表及一臺(tái)監(jiān)控主機(jī), 設(shè)計(jì)了32 路可接多種類型傳感器的模擬量輸入通道，并采用PROFIBUS 現(xiàn)場總線,可以和其它廠家生產(chǎn)的符合PROFIBUS 現(xiàn)場總線TN915 協(xié)議的儀表配合使用,符合當(dāng)前國際上控制系統(tǒng)發(fā)展的趨勢。

Abstract: In order to solve the shortages of current monitoring system, such as structure
complexity, high price and inconvenienced maintenance, a multi-purpose monitoring system based the PROFIBUS was proposed in this paper. It includes the monitoring module and a host, and 32 analog input paths were designed as well, which can fit various sensors. The PROFIBUS bus used in the system can accord with other system, so it is with the modern international developing trend.
