336 フィールドバスを用いた熱プロセスの異常診断 : 第3報 機器監視とプロセス診断の統合(システム適用, OS-18 計測・評価・診断)

抄録

In order to disseminate distributed energy systems, an autonomous diagnosis of the system is imperative. The purpose of this study is to develop the diagnosis method using the fieldbus technology, which makes it possible to share much information of field devices. The authors constructed an experimental apparatus of a heat exchanging process, which is one of the key component of distributed energy systems and a measurement and control system with fieldbus devices. In this paper, the integration algorithm of the process diagnosis on the basis of the calculation of the overall heat transfer coefficient and the device monitoring using the statuses in the FOUNDATION fieldbus was developed and its effectiveness was confirmed experimentally.
