Plenary Lecture 8 A Better Environment through Better Terology

摘要

A better environment can be achieved through the decreased emission of pollutants and the optimizationrnof the production of green energies. Also, making maintenance interventions as effective and efficient as possiblernplays an important part in getting equipment to function as well as it can and, no less importantly, in minimizing therndowntime caused by faults. The paper summarizes the latest developments in the areas of decreased emissions andrngreen energy production achieved by the author and his team, highlighting the most recent aspects of this group'srnresearch, namely 3D models for fault diagnosis.rnThe paper will also describe the current position of several projects that contribute to a better environment, includingrnon-condition maintenance for wind farms. This is based on the remote acquisition of data through IP networks andrnalso on the introduction of new protocols and low-cost hardware, in order to implement local solutions for collectingrndata in each wind generator. The paper will also discuss and make proposals concerning prediction algorithms basedrnon data series models.rnAnother way of safeguarding the environment is by reducing Diesel engine emissions, particularly in urban buses,rnthrough the achievement of emission levels lower than the most recent standards. However, as this involves politicalrndecisions, it would need to be implemented through concrete systems that, in this case, use new algorithms based onrnHidden Markov Chains, which are proving to be a good predictive tool.rnThe above proposals are being added to a core system called SMIT (Integrated Modular System for Terology), whichrnhas a modular structure, like a jigsaw puzzle that grows in response to new developments and the challenges thatrnorganizations face.rnCurrently, further new research projects are being undertaken, such as integrated asset management from anrnenvironmental perspective, which will allow the optimization of the integration of international standards, with thernobjective of organizing and planning maintenance with the environment as a major consideration.rnAnother interesting project is related to aiding fault diagnosis through the use of 3D models that, in the near future,rnwill enable causes of faults to be identified as efficiently as possible. However, if this project is to make a significantrncontribution in this area, it will only be through developments achieved by global collaboration using the web and freernsoftware resources, as this will minimize the time required for the development of new models.
