[0002] With the rapid development of my country's economy and the increasing demand for water transportation, ports of various types and sizes are constantly expanding and expanding. In particular, the rise of ultra-large container terminals has put forward higher requirements for the intelligence level and operational efficiency of ports. At the same time, the joint logistics dispatch of intelligent port transportation and railway transportation has become a new trend. The gates and waterway gates of traditional ports are usually controlled by manual operation, relying on dock workers to manually open and close the gates based on experience. This operation method has certain safety risks and low efficiency. With the development of technology, some advanced ports have begun to use automated control systems to operate gates. Existing automated control methods are mainly based on preset fixed control strategies, lack real-time adaptive capabilities, and cannot cope with complex and changeable port hydrological and waterway conditions.
