This product utilizes CCTV video information and deep learning technology, in conjunction with weather-related external agency data, to perform real-time quantitative measurements of water levels, flow rates, and discharge in areas such as valleys, small rivers, underground tunnels, and roads. Based on this data, an artificial intelligence AI assesses the level of danger, replacing human evaluation, and issues flood alerts and warnings. It serves as an integrated decision-making system capable of controlling access barriers and sluice gates.
