Abstract:

The deep integration of information technology and manufacturing industry has promoted the rapid development of intelligent manufacturing and Industrial Internet. However, there are a number of problems in the industry, such as various types of equipment, various equipment manufacturers, different interfaces, and many communication protocols, which lead to the existence of unconnected “information islands” between equipment. Therefore, current status and problems of the interconnection and interworking of industrial field equipment are analyzed from three aspects: industrial communication, field devices integration, standardization. Then a standardized and reusable solution for the interconnection and interworking of industrial field equipment is proposed in which OPC UA, information model and gateway platform are integrated as a whole.

Key words: industrial field equipment, interconnection, industrial communication, field device integration, intelligent manufacturing
