A Realization of Cyber-Physical Manufacturing Control System Through Industrial Internet of Things

A Cyber-Physical System in Industry 4.0 is with interconnected elements of cyber and physical worlds. However, the interconnection relies on the success of communication among the equipment, sensors, controllers with different data and communication standards. (Protocols) This research takes an approach of applying Industrial Internet of Things (IIoT) to integrate the sensing data from various equipment and sources. Industrial Micro Control Unit (MCU) is applied to interface with the data sources, actuators, and equipment. The MCU transmits the sensing data/control commands back and forth with the cloud/fog computing platform. By deploying data analytics and reasoning for the manufacturing knowledge ontology in the cloud platform, the cyber world is able to recognize the situations and problems in the physical world. Thus, a decision of preventive or predicative actions can be made in the cyber world and then be implemented in the physical world. The results show that IIoT can eliminate the problems of heterogeneous protocols and databases in manufacturing data transmission. Based on IIoT, CPS is realized without the concerns or difficulties of data transmission
