Abstract: To satisfy manufacturing process management and maintenance requirements from agile manufacturing, the prototype of Intelligent Maintenance Unit (IMU) of manufacturing system was studied and constructed. Relevant products information from home and abroad were analyzed. The primary architecture and implementation techniques of Internet-based embedded IMU were introduced. Furthermore, remote maintenance system model was set up and application examples were given. To cater to needs of high reliability, networking and intelligence of the monitoring system, grid maintenance solution and key supporting technologies of the system based on integration of IMU with multi-parameters were proposed. And their application fields and research prospects were also given. It provided a sound and reliable e-maintenance mechanism for Computer Integrated Manufacturing (CIM) and sustainable value of products/equipments during lifecycle.
