Abstract: Depot management is transformed into refined management, intensive operation and maintenance, and intelligent dispatching through integrated and informatized management methods. The Metro Vehicle Base Integrated Automation System（MDIAS）,as a comprehensive platform for metro depot management,centrally manages information of various professional equipment in the field, and uses information fusion technology to classify and categorize equipment alarms. The alarm information is linked to PMS and the construction scheduling system. Work orders are dispatched and construction plans are created automatically.Thereby the depot operation and management workflow is improved, as well as the automation and information scheduling level of the depot operation. The centralized alarm information management function of MDIAS is introduced.
