| Abstract: | This paper used intelligent Internet of Things technology to obtain real-time monitoring live data of stagnant water,and obtained Tianjin’s fine-grained meteorological grid forecast products and live data from the city’s automatic rainfall observation stations.Based on the machine self-learning,neural network model and the classification principle of urban waterlogging risk classification in Tianjin,the paper studied the technology of urban waterlogging prediction and early warning based on the real-time location of users,and developed the automatic water logging monitoring and warning system in Tianjin.The results showed that the system had a certain capability of monitoring,early warning and forecasting of urban waterlogging risks.In the application of multiple major weather processes from 2018 to 2020,the results of the depth prediction of the accumulated water were basically consistent with the monitoring results,and the application data showed that the verification results were ideal.The system can provide accurate and timely meteorological data support for government disaster prevention and mitigation decision-making,command and scheduling. |
