Problems solved by technology

[0003] The ship electric propulsion system is a relatively advanced propulsion method. Its energy-saving, environmental protection and safety performance are very suitable for inland river ships. However, the driving environment of inland waterways is complex, and the water depth and current conditions change frequently, resulting in large fluctuations in the operating load of ships. The output power of the diesel engine cannot follow the changes quickly, resulting in the defects of poor operating conditions and high fuel consumption of the diesel engine
In addition, the inland waterway is narrow, there are many sharp bends and dangerous beaches, and there are many ships that need to avoid and cross each other. The requirements for the maneuverability of the ship are relatively high. The conventional electric propulsion system and propulsion structure cannot meet the high maneuverability requirements of the ship operation.
[0004] The patent "a pod-type full-turn ship electric propulsion system" (ZL201811655171.2) uses at least one set of power generation units. The system is connected to a pod-type azimuth propulsion system with a synchronous motor inside. A telescoping mechanism is provided on the propeller hub of the azimuth propulsion system to adjust the diameter of the propeller, and then adjust the thrust of the propeller; however, the electric propulsion system adopted in this patent cannot be based on The operating load of the ship changes the output power of the power system, which easily causes energy waste
[0005] The patent "a sailing control method for a ship's propulsion system" (ZL200810034634.3) uses two sets of propulsion motors installed symmetrically on the left and right and a full-turn propeller to form a ship propulsion power plant. Through propulsion control and rotation control, the speed and angle control of the propeller is realized; However, this method does not consider the control of the output power of the full-turn propulsion system when the ship's operating load fluctuates. At the same time, the ship's navigation control method only considers the ship's target speed and course, and does not consider the requirements of the ship's target position for navigation control. Under the conditions of fixed-point docking and other conditions, it cannot meet the navigation requirements of high maneuverability of inland river ships. In addition, when ships or obstacles suddenly appear in the navigation track during the automatic navigation of the ship, the ship cannot avoid it in time.
