Design of Urban Waterlogging Monitoring and Early Warning System Based on Internet of Things Technology

With the acceleration of urbanisation, the problem of urban flood prevention is becoming more and more serious, and urban flooding caused by large-scale rainfall poses a serious threat to people's lives and urban infrastructure. In order to effectively deal with urban flooding, this paper proposes an urban waterlogging monitoring and early warning system based on internet of things Technology, aiming to reduce urban flooding through real-time monitoring, data analysis, intelligent early warning, and effective scheduling. This paper designs the overall architecture of the system, including hardware composition and software design, and provides an in-depth analysis of the main modules. The effectiveness of the system is verified through testing, and the results show that the system has high real-time and reliability.
