Research Of Control And Management Technology For Discrete Manufacturingprocess Based On Internet Of Things

The launch of “Industry 4.0” project in German is setting off a new round of industrial revolution. Internet of Things and Service Network are the foundation of implementation. RFID is a key technology of Internet of Things. Up to now, the adoption of RFID is accelerating in retail, supply chain, logistics, manufacturing and other domains. This change is being driven by rapid improvements in the technology, and by successful deployments that have proven the values of RFID. In contrast to the typical utilization in warehouse management, supply chain and automotive manufacturing, this paper adopts Internet of Things to control and manage the discrete manufacturing process.In the support of National Defense Basic Scientific Research, considering of the poor data acquisition and inefficient control and management during the discrete manufacturing process, this paper studies the real-time status monitoring, data management, and production scheduling technologies based on Internet of Things, the main research contents are as follows:Firstly, analyzed the requirements of discrete manufacturing to Internet of Things, combined with the characteristics of its mode, a new system mode and architecture were presented for the control and management in discrete manufacturing process based on Internet of Things, and several key technologies were introduced briefly.Secondly, based on the analysis of static and dynamic data from discrete manufacturing process, UML models for production elements were given, the multi-view of discrete manufacturing data was analyzed, and the real-time status matrix was built. Then RFID-based data encoding rules for production elements were formulated. The adoption of XML technology was responsible for data management.Thirdly, dynamic scheduling technology in discrete manufacturing was introduced, and RFID-based schemes were studied. Based on the real-time discrete manufacturing environment, analyzed the model and rule for production dynamic scheduling, and put forward an RFID-based visibility dynamic scheduling rule to control discrete manufacturing process.Finally, a service-oriented system function and database were designed, and a demonstration system was developed. The study realized the deployment of RFID technology in discrete manufacturing environment. Processes and functions of this system were verified successfully.
