MODERN MAINTENANCE SYSTEM BASED ON WEB AND MOBILE TECHNOLOGIES

The paper illustrates the development of an e-monitoring and e-maintenance architecture and system based on web and mobile device, i.e. PDA, technologies to access and report maintenance tasks. Rarity of experts led to the application of artificial intelligence and later, distributed artificial intelligence for condition monitoring and diagnosis of machine condition. Recently, web technology and wireless communication emerged as an alternative to provide maintenance with a powerful decision support tool which makes it possible to have all the necessary information wherever it is needed for maintenance analysis and its various tasks. The paper goes through the characteristics of using web and mobile devices for condition monitoring and maintenance. It illustrates the ICT used to communicate among the different layers in the architecture/system and its various client machines. The practical examples are related to the maintenance of rotating machinery, more specifically, diagnosing rolling element bearing faults.
