Abstract:Under the trend of digital transformation and intelligent development of nuclear power plants, the demand for implementing intelligent projects in the field of engineering construction is becoming increasingly strong. This article introduces the construction background of the intelligent construction site platform of the Tianwan Nuclear Power Plant and the key technologies used, such as 5G+MEC wireless network technology and edge computing technology, Beidou+Bluetooth positioning technology, video surveillance and AI intelligent analysis techniques. The article introduces the functional architecture of the intelligent construction site platform from the main functions. The project realizes 5G wireless network full coverage in the engineering construction area, real-time video surveillance, AI real-time analysis and early warning of engineering safety supervision behaviors, real-time positioning and warning of personnel and vehicles at the construction site, linkage with the broadcasting system at the construction site, real-time environmental monitoring at the construction site, and access control and real-time personnel management at the construction site. The article analyzes the application effects and related operation and management systems. Through the implementation of the platform, the response speed and event handling speed are achieved, passive management is transformed into active intelligent management, and the management level and efficiency at the construction site are effectively improved.
