Composition of Intelligent Manufacturing System in China
Intelligent manufacturing system architecture is constructed through three dimensions: life cycle, system level and intelligent function. It mainly solves the modeling research of intelligent manufacturing standard architecture and framework. As shown in the figure above.
Life cycle is a chain set of interrelated value creation activities such as design, production, logistics, sales and service.
The system level includes equipment level, control level, workshop level, enterprise level and collaboration level. The system level of intelligent manufacturing embodies the trend of intellectualization of equipment, Internet Protocol (IP) and network flattening.
Intelligent functions include five layers: resource elements, system integration, interconnection, information fusion and emerging formats.
(1) Resource elements include physical entities such as design and construction drawings, product process documents, raw materials, manufacturing equipment, production workshops and factories, as well as energy sources such as electricity and gas. In addition, personnel can be regarded as an integral part of resources.
(2) System integration refers to the integration of raw materials, spare parts, energy, equipment and other manufacturing resources through two-dimensional code, radio frequency identification, software and other information technologies. Integration from smart equipment to intelligent production unit, intelligent production line, digital workshop, intelligent factory and even intelligent manufacturing system is realized from small to large.
(3) Interconnection refers to the interconnection between machines, between machines and control systems, and between enterprises through wired and wireless communication technologies.
(4) Information fusion refers to the use of cloud computing, big data and other new generation of information technology on the basis of system integration and communication to achieve information collaborative sharing under the premise of ensuring information security.
(5) Emerging industries include personalized customization, remote operations and industrial cloud manufacturing.
