This invention relates to the field of ship braking control, in particular to a braking control system to ships by electric propulsion
Ship is a kind of man-made transportation vehicle that mainly runs on water. In addition, civilian ship are generally called ship, military ship are called naval vessel, and small ship are called light boat or boat. In generic terms, they are called ship or boat, their interiors mainly include accommodation space, supporting structures and drainage structures, and they have propulsion systems using external or self-generated energy, their appearance generally adopts a linear envelope model that is good at overcoming fluid resistance. The making materials are constantly updated with the progress of science and technology, in the early days, they were natural materials such as wood, bamboo and hemp. In modern times, most of them are steel, aluminum, fiberglass, acrylic and various composite materials. There are many classification methods for ships, which can be according to their use, sailing status, hull number, propulsion power, propeller, etc.
Electric propulsion ship refers to modern ships propelled by electric power. Many modern ships are propelled by electric power, which comes from batteries or marine generators. Some small surface ships or underwater ships use diesel engines or steam turbines to drive generators to generate electricity and rotate propulsion motors to propel the ships. When the ships need emergency braking in the process of traveling, the workers control the motor to reverse through the control switch, so that the propeller can reverse for retarding braking. However, due to the large size of the ship, after the turning of propeller is reversed, the ship can still move forward by its own inertia, which lowers the safety of the ship in running. Therefore, we propose a braking control system for electric propulsion ship.
