Integration and Application of 5G Ultra-Reliable and Low-Latency Communications in Networked Control Systems for Intelligent Factories

Abstract

Computer-based Network Control Systems (NCS) are key technologies for achieving smart factory operations. NCS can operate stable-state coordination, distributed monitoring, and automated control in an Industry 4.0 environment. This paper analyzes how 5G ultra-reliable low-latency communication technology (URLLC) can best be integrated into industrial application network control systems. To ensure response determinism in critical mission applications, a hierarchical system architecture is developed, integrating edge, fog, and cloud layers to achieve an enhanced 5G wireless network. Considering the overall model of protocol layer optimization for reliability and latency, dynamic resource management redundancy solutions are suitable for complex industrial environments. In terms of operational risk, conduct probabilistic risk assessments on various attack surface dimensions to determine the hazards. Experimental validation conducted Through scale simulators and hardware-in-the-loop testing platforms shows that the control accuracy and reliability of 5G URLLC significantly surpass those of existing systems. Implement multi-layer security protection, reliable network data security transmission methods, and systems that identify abnormal behaviors that may threaten operational continuity. The conclusion of this study is: 5G URLLC meets the stringent requirements of industrial automation and can serve as a long-term flexible foundation to drive smart manufacturing processes in digital and integrated cyber-physical systems (CPS).
