Embodiment Construction
[0060] The present invention will be further described below in conjunction with the examples, and the contents of the examples are not intended to limit the protection scope of the present invention.
[0061] For the autonomous anchoring of smart ships, the optimization process is divided into two stages. The first stage is how to use the propeller of the ship to maintain a suitable ship position, and the second stage is how to realize the entire anchoring process quickly, economically and safely.
[0062] For the first stage, in order to ensure that the unmanned ship can safely enter the anchorage area, and realize the control and maintenance of the ideal ship position in the anchorage, it is necessary to combine the dynamic positioning system of the ship (that is, each propeller) to realize the control of the ship's ship position. achieve and maintain.
[0063] In order to achieve the goal of the first stage, in addition to considering the energy consumption requirements, e...

The present invention relates to an autonomous mooring optimization method for an intelligent ship, comprising the following steps: (1), optimizing the energy consumption, error, mechanical characteristics of each thruster of the mooring ship and the relative position between the mooring ship and other ships around, and obtaining energy consumption and The minimum error, the relative position of the anchored ship and other surrounding ships is the closest to the minimum standard distance, and the mechanical characteristics meet the requirements of the speed and thrust angle of each propeller, according to which the position and heading control of the anchored ship can be realized, so that it can keep anchored Ship position; (2), optimize the power consumed by each propeller of the anchoring ship and the power consumed by the windlass, and obtain the speed and thrust of each propeller under the minimum power consumed by each propeller and the power consumed by the windlass The angle and speed of the windlass, according to which the anchoring process of the anchored ship is achieved. It can optimize the anchoring process according to real-time conditions, and improve the economy and efficiency of the entire anchoring process.
Description
technical field [0001] The invention belongs to the technical field of ship mooring, relates to a ship mooring optimization method, in particular to an intelligent ship automatic mooring optimization method. Background technique [0002] Anchoring refers to the positioning method of mooring floating structures or ships at sea with anchor cables, anchor chains and anchors, so as to limit the drift caused by external forces and keep them at the predetermined position. [0003] For manned ships, the anchoring operation mainly depends on human experience. However, for smart ships, since no one is on board, the corresponding anchoring operations cannot be performed by human experience, so autonomous anchoring technology has become one of the indispensable technologies in the development of smart ships. [0004] Autonomous anchoring operation requires the use of sensors to feed back a series of signals of the navigation environment and the ship's own state, which are converted in...
