  • June 12: Zero failure: the promises and challenges of predictive maintenance

    The Internet of rail, smart maintenance of passenger access doors for tomorrow’s rail mass transit

    Passenger Access Doors account for a significant share of a rail mass transit system life cycle cost (LCC). Door failures typically cause heavy disruption in operations and, if too frequent, are very detrimental to the operator’s and the OEM’s image. Alstom’s R&D program addresses both concerns through a PHM (prognostics & health management) approach: substituting predictive maintenance (based on asset condition) for traditional systematic preventive maintenance (based on mileage). Features extracted from continuously monitored data, such as motor current and voltage and door position, are used in order to build a ‘health indicator’, which is a distance to normality. Main benefits are: 1. Availability increase: degradations detected before evolving into service-affecting failures and maintenance crews advised soon enough to act. 2. Cost reduction: unnecessary maintenance actions avoided
