Research on the Application of Internet of Things (IoT) Technology Based on Door Magnetic Induction in Intelligent Management of Safety Prevention and Control for Confined Spaces of Nuclear Power Units

With the continuous progress of technology, the application of the Internet of Things technology in the management of nuclear power units is becoming more and more in-depth。 This paper focuses on the Internet of Things technology for nuclear power plant door locks based on door magnetic induction, aiming to achieve logical interlocking between door, remote control of door lock switching, and to improve the safety and management efficiency of nuclear power plant operation. This paper elaborates on the working principle and characteristics of the door sensor, and deeply explores the application architecture of the Internet of Things technology in this system, including the design of the perception layer, network layer and application layer. Through the collaborative development system hardware and software, the functions of real-time monitoring of door status, remote unlocking, multi-door logical interlocking, emergency alarm, data statistics and other functions realized. At the same time, a comprehensive analysis of the security and stability of the system is carried out, and corresponding safeguard measures are proposed. The research results show that the system effectively meet the needs of remote control of door locks in nuclear power plants, and introduce non-intrusive intelligent management, which has important practical application value and promotion prospects。
