The Construction Of Water Treatment Operation System Using Fieldbus

필드버스(Lonworks)를 이용한 수운영시스템 구축

Water Treatment Operation System is applied in most water treatment plants with DCS(Distributed Control System) or PLC(Programmable Logic Controller) system. But it has a lot of problems in viewpoint of cost and expansibilities. Therefore, we rose demand about a system that it was easier, convenient and a few costs. So, It was appeared at a Fieldbus as an alternative about this. It is used in ail industrial fields, but because of the economic reality that we can't removes the existing system, and cannot introduce new technology. Because it is actual to be hard to find an actual implementation reward and way of domestic fieldbus technology, we cannot be acknowledged with reliability in the industrial spot. Therefore, We is going to look into a fieldbus application reward in this paper. That is, We recognize structure and a kind of a fieldbus in a Chapter 2. And we is going to look into difference between a PLC method and fieldbus methods in a Chapter 3. Also, We are going to compare the system that used PLC with the system that used fieldbus (LonWorks). And the objects are JinAn and Wonju where a field bus was applied to.
