Abstract

This invention relates to the field of intelligent flood control and drainage early warning technology for urban areas, and discloses an intelligent flood control and drainage early warning method for urban areas. This flood control early warning system integrates precipitation monitoring, drainage well rated drainage capacity assessment, accurate detection of wellhead water flow velocity, and image recognition technology. By acquiring real-time precipitation and drainage well rated data, and combining multiple water flow velocity detectors to perform detailed analysis of wellhead water flow distribution, the system also utilizes cameras and image recognition to determine the wellhead condition. Based on changes in drainage volume and wellhead conditions, the system flexibly responds to complex situations such as a sharp drop in drainage volume accompanied by foreign objects, a rise in stable water levels reaching the rated capacity, and a rise in stable water levels below the rated capacity, formulating and executing corresponding early warning strategies. Furthermore, the system can quickly locate and notify personnel within a 1-kilometer radius, instantly transmitting flood information via SMS to ensure that those affected by flooding are informed of the situation immediately, effectively improving flood control efficiency and safety.
