Multiplexed Internet of Things Data Transmission and Visualization Utilizing Wireless LAN Authentication and Privacy Infrastructure Protocol in Smart Factories

In high-security environments, such as smart factories and power networks, secure and reliable data transmission and device access are crucial. This paper proposes a diversified Internet of Things (IoT) data transmission and visualization solution based on the Wireless LAN Authentication and Privacy Infrastructure (WAPI) protocol. First, we introduce the technical characteristics of the WAPI protocol and analyze network access solutions relevant to smart factories, along with their application requirements in power networks. Addressing gaps in the existing literature, we present a comprehensive solution that encompasses network deployment, device management, device testing, and data transmission, highlighting its completeness and effectiveness in real-world applications. Furthermore, we provide detailed experimental evidence demonstrating the WAPI protocol's effectiveness and security in supporting multiple terminal device access within high-security settings. The findings of this research not only fill critical gaps in existing work but also provide valuable technical support and reference for secure data management and real-time monitoring in smart-factory environments.
