DYNAWEB. A WEB PLATFORM FOR FLEXIBLE PROVISION OF E-MAINTENANCE SERVICES

摘要

Actual industrial maintenance activities are mainly driven by traditional strategies where events are normally time-based. Though it has been pointed that more advanced, condition-based strategies can provide clear savings in many maintenance activities, their application is normally prevented by different causes, such as the need to manage, both physically and logically, an increasing volume of data and information. This paper presents the development of a flexible architecture concept to provide flexible data and information management. On the one hand, a platform of web services to provide intelligent processing capabilities has been designed. This platform is logically structured according to OSA-CBM decision layers, from Condition Monitoring to Decision Support, and will provide automated results extraction for maintenance staff out of the existing data sources, with a flexible configuration that allows the system to be used 'on-demand' and to grow according to the needs (new sensors and functionality). On the other hand, this software platform is supported by a flexible communications infrastructure, where a generic wireless 'gateway' device is being developed, in order to complement existing communications options (wired or wireless) between sensors and company decision areas when other communication options are not available (such as SCADA, PDAs, etc.). This development, nicknamed DYNAWeb, is still ongoing and takes part of the DYNAMITE project, where additionally other technologies are being developed.
