Automatic ship control system and method with reliance on heading signal

Abstract

The invention discloses an automatic ship control system and method with reliance on a heading signal. Ship position information, a command rudder angle, an actual rudder angle, a hull revolution angle rate and set trace and route data are collected; an optimal track state amount is obtained based on the ship position information and the hull revolution angle speed; and according to the optimal track state amount, the ship position information, the command rudder angle, the actual rudder angle, and the trace line and route, a helm shift command signal is obtained and rudder blades are driven to make rotation, thereby realizing automatic controlling of the ship. According to the invention, automatic control of the ship under the condition of being lack of a heading signal is realized; the labor intensity of the worker is reduced; and the economic benefits and the safety of the navigation of the ship are improved substantially.

Description

technical field [0001] The invention belongs to the technical field of ship maneuvering and control, and is a solution to the lack of heading signals during ship navigation, and in particular relates to an automatic ship steering system and method that does not rely on heading signals. Background technique [0002] Ship automatic steering control has become the main way of ship steering control. The basic principle is to use the ship motion information transmitted by various navigation equipment in the automatic steering equipment, and give the steering control signal through the corresponding control algorithm to control the steering gear properly. Turn the rudder, and then make the ship sail according to the required sailing plan, such as automatically keeping on a given course, that is, heading control, and automatically sailing along the set route, that is, track control, etc. The ship motion information mainly includes rudder angle information, heading information and p...

Problems solved by technology

[0005] However, the above-mentioned manipulation method will significantly increase the intensity of manual work, and due to the inaccuracy of manual control, the voyage will be significantly increased and the fuel consumption will increase. Usually, it is only suitable for small ships to operate in the offshore, and is not suitable for long-distance sea voyages.

At present, in order to improve economic efficiency, many fishing boats expect to go fishing in open sea waters, so such small fishing boats without compass equipment cannot realize high sea navigation only by manual manipulation.

At present, the degree of automation of some large cargo ships is getting higher and higher, and the number of crew members is getting smaller and smaller. After the ship's heading signal is lost, the autopilot equipment is paralyzed and the ship cannot be controlled automatically. The ship can only be controlled manually, because the crew less, it will significantly increase the intensity of labor operations, and cannot guarantee the accuracy and safety of ship manipulation
