This paper analyzes the development status of intelligent channels both in China and abroad and proposes an AI monitoring and navigation-supporting system that integrates a water level prediction model，video recognition technique，integrated embedded GPS chips，relevant hardware equipment，and interactive operation interface. With Minjiang River（Longxikou-Hejiangmen section） as the research object，the system identifies，collects，and analyzes channel dynamic information such as water level，ships，and beacons. As a result，it achieves intelligent management of channel resources，improves the efficiency of channel supervision and operation，and assists channels’ competent departments in decision-making. The system can exert positive effects in speeding up the intelligent construction of Sichuan’s channels and helping the transportation industry realize carbon neutrality and carbon peaking.
