Tiivistelmä
The increasing importance of condition monitoring in the manufacturing industry has prompted many new developments in the area. While some have focused on different ways of processing monitored data, few have touched the subject of the communication network components, protocols, and standards used in monitoring networks. Additionally, monitoring systems have traditionally been built on top of existing network architectures further complicating the factory floor network by introducing additional communication protocols. At the same time, Web Service based solutions have been implemented in the upper levels of the manufacturing industry, namely the corporate network.
Proposals implementing Service Oriented Architecture (SOA) based approaches that ease the communication exchange for scheduling, ERP and MES systems have been created. While the use of this technology has brought many improvements, the extent of the potential benefits that Web Services can provide have been limited by the scope to which they have been applied to. This thesis proposes a solution that brings the SOA paradigm to the lower levels by utilizing Web-Service embedded intelligent devices. It does so by analyzing the particular case of the lubrication flow monitoring systems used in the paper industry. The fact that the average paper machine requires anything between 600 and 1500 lubrication points presents a unique opportunity to implement a Web Service based system where there is a need to monitor huge amounts of sensors and flowmeters in a distributed manner.
Lastly, this thesis evaluates existing circulating oil flow monitoring architectures, and uses this analysis to propose a potential improvement that brings Web Services to the condition monitoring arena. Tests that evaluate the performance parameters of intelligent Web Service capable devices, and their results are presented. The reliability and overall behavior of the proposed system is analyzed and scrutinized. /Kir10
