Abstract:

The applications of condition monitoring technologies, i.e. oil monitoring offline, oil monitoring online, vibration monitoring, current spectrum and infrared imaging, to intelligentized maintenance and health management of shield are studied by taking the main bearing, main drive gearboxes, hydraulic systems and other core components and systems of shield as monitoring objects, in response to the problems of shield, i.e. complex structure, multiple systems, lack of condition monitoring for core components and low maintenance level. Furthermore, a laboratory information management system is developed； meanwhile, a unified management and exchange platform is established for technology, management, maintenance personnel and condition monitoring equipments based on internet; and a condition monitoring and fault diagnosis knowledge database is set up to realize intelligentized maintenance and provide reference for the maintenance and health management of shield.

Key words: shield, condition monitoring, maintenance, laboratory information management system, internet
