Design of an Intelligent Flood Control Inspection well System Based on Pseudorange Differential Joint Carrier Phase Algorithm

Aiming at the technical problem of insufficient positioning accuracy in monitoring and early warning of urban flooding, the research on the optimization of pseudo-range difference algorithm, the application of carrier phase algorithm, and the research on Internet of Things and big data processing technology is carried out from the introduction of high-precision positioning technology, the real-time monitoring of the water level in inspection wells, and the fusion of data [1]. Using the pseudorange difference combined with carrier phase algorithm, big data analysis platform and other technical methods, the system realizes the high-precision determination of inspection well position, real-time monitoring and warning of water level, and intelligent processing and analysis of data. The system simulation experiment was carried out by applying professional simulation software, and when an abnormal situation occurs, it is able to send out warning information in time to remind the management personnel to manage [2]. The results show that the technical solution of intelligent flood prevention inspection well system based on pseudo-range differential joint carrier phase algorithm has feasibility and effectiveness in improving the efficiency of urban flood monitoring and early warning.
