Digital intelligent manufacturing mode innovation and industrial performance analysis based on industrial internet of things cluster

In recent years, with the rapid development of China's technological level, internet business has also increased, resulting in a shortage of wireless spectrum resources. Therefore, relevant scholars have introduced device direct communication technology into communication networks. Traditional cellular networks improve utilization efficiency and system capacity by introducing device through technology, and can also reduce the transmission pressure of base stations. However, this solution allows cellular users and device through users to share resources simultaneously, and each user may cause interference before. When the interference is severe, users cannot use the communication system. Therefore, this article proposes a communication resource allocation algorithm based on a proportional algorithm, which can enable users to experience better usage effects and leverage the performance advantages of device direct communication technology. Intelligent manufacturing can reflect the industrial competitiveness of every country, and China also attaches great importance to the development of intelligent manufacturing and increases efforts to support intelligent manufacturing. The manufacturing industry of intelligent systems is carried out through the industrialization of computers, promoting system optimization and upgrading. This article studies and explores the clustering of industrial IoT and digital intelligent manufacturing, applying these technologies to wireless resource allocation, thereby promoting the development and improvement of intelligent systems.
