Description

Technical Field

[0001] The invention relates to a steering gear control method for a ship with dynamic positioning function. Background Art

[0002] At present, for marine engineering vessels with dynamic positioning function, the selection of propellers and steering gears will be slightly different according to the different customer usage requirements. Some ships use full-turn propellers (a propeller or ducted propeller that can rotate 360° around a vertical axis) to generate rudder force through the propeller's own angular rotation; many ships still use a combination of propellers and steering gears for propulsion. The steering gear control system of ordinary merchant ships is usually controlled by an automatic rudder system, which is mainly divided into three operating modes: automatic rudder, follow-up rudder and non-follow-up rudder. For marine engineering vessels with dynamic positioning function, if traditional propellers and steering gears are used, their steering gears must be controlled by the dynamic positioning system in addition to the automatic rudder system in the dynamic positioning mode. The steering gear needs to be installed with an independent control system to meet the above usage requirements. Therefore, the system is relatively cumbersome and the crew is prone to errors in operation. Summary of the invention

[0003] The object of the present invention is to provide a steering gear control method for a ship with a dynamic positioning function.

[0004] The technical solution adopted by the present invention to achieve the above-mentioned purpose is: 1. A steering gear control method for a ship with dynamic positioning function, comprising the following steps: Step 1, when the rudder control function is switched from the follow-up rudder mode to the dynamic positioning system control mode, and the control position is switched from the front desk to the back desk of the cab, the follow-up rudder / dynamic positioning mode button (1) of the rudder control function mode switching controller is pressed, and the indicator light of the follow-up rudder / dynamic positioning mode button (1) is lit. The rudder control function mode of the autopilot control system has been set to the follow-up rudder / dynamic positioning mode. At this time, it is normally in the follow-up steering mode. The follow-up rudder mode in use indicator light (11) of the steering position switching control panel is lit. If the mode switching is unsuccessful, the switching fault alarm (5) will sound an alarm. When the dynamic positioning system control station issues an instruction to apply for steering authority, the cabin front desk to back desk position switching alarm (9) on the steering position switching control panel sounds an alarm. At this time, the cabin front desk to back desk confirmation button (7) is pressed, and the indicator light of the cabin front desk to back desk confirmation button (7) is lit. The follow-up rudder mode in use indicator light (11) on the steering position switching control panel goes out. At this time, the rudder control is switched from the follow-up rudder mode to the dynamic positioning system control mode, and the steering position is switched from the front desk to the back desk of the cab. Step 2, when the steering control function is switched from the dynamic positioning system control mode to the automatic steering control system mode, the control position is switched from the backstage of the cab to the foreground, and after the dynamic positioning system control station issues an instruction to apply for returning the steering right, the backstage to foreground position switching alarm (10) on the steering position switching control panel sounds an alarm, and at this time, the backstage to foreground confirmation button (8) is pressed, and at the same time, the indicator light of the backstage to foreground confirmation button (8) on the steering position switching control panel lights up, and the follow-up rudder mode in use indicator light (11) on the steering position switching control panel lights up, and at this time, the steering control is switched from the dynamic positioning system control mode back to the follow-up rudder mode, and the steering position is switched from the backstage of the cab to the foreground.

[0005] In step 1, the rudder control function mode switching controller is also provided with an automatic mode button (2), a non-follow-up rudder independent mode button (3), a non-follow-up rudder synchronous mode button (4) and a control panel indicator light brightness adjuster (6).

[0006] In step 1 and step 2, the steering position conversion control panel is also provided with a steering position conversion control panel indicator light brightness adjuster (12).

[0007] The present invention discloses a steering gear control method for a ship with a dynamic positioning function. The steering gear is controlled by an automatic steering system, and no independent steering gear control system needs to be installed additionally. The system configuration has a high degree of integration and the operation by the crew is relatively simple. BRIEF DESCRIPTION OF THE DRAWINGS
