Abstract: To solve the problems of perception and access difficulty of a large number of heterogeneous devices and long time-delay of data analysis in cloud intelligent manufacturing and smart service applications,the characteristics,application scenarios and access models building of manufacturing resources perception and access for edge computing were discussed.Edge intelligent gateway software system was developed for realizing a variety of communication protocols,data collection and distribution,applications management and security protection functions,and the cloud-edge collaboration service architecture for manufacturing resources perception and access was designed.The importance and tasks of edge intelligent gateway under the cloud-edge collaborative service mode were analyzed.In the complex equipment intelligent manufacturing production line and virtual factory application system,demonstration application was achieved,meanwhile manufacturing resources perception and access technology for edge computing and the edge intelligent gateway functions were verified.

Key words: edge computing, cloud manufacturing, resources perception, intelligent gateway, perception and access, cloud-edge collaboration service architecture
