Development of the intelligent dust chamber bag control system using Case-Based reasoning
Jung-Sook Kim · 2010
The phrase, 'convergence technology,' refers to the synergistic combination of conventional industry and IT (Information Technology) including advanced computing and communications. The growing recognition of the urgency to reduce risks and production costs is motivating the development of improvements in the traditional manufacturing industry using IT convergence. This paper describes the IT convergence application which is a combination of traditional dust chamber industry and the Internet, using Power Line Communication (PLC) and Case-Based Reasoning (CBR). At first, we developed a connection method between a differential pressure transmitter that is a sensor of the dust chamber and PLC modem. Also, we designed a message format to transmit the data from a PLC modem to a user and from a user to a PLC modem. The transmission data unit in the PLC modem is a byte and we defined the n-bytes message format. In addition to that, we developed object modeling, dust chamber modeling and event modeling, based on XML (extensible Markup Language) using the object-oriented modeling method. And we applied case-based reasoning to intelligently find the optimal exchange time for dust chamber bags. The experimental results on the developed system are also presented.
