Embodiment Construction

[0017] The present invention takes the "Ocean No. 1" ocean-going scientific research vessel as an embodiment.

[0018] A method for dynamic positioning of a ship, the specific steps of the method are as follows:

[0019] 1) Select the dynamic positioning control system to the required mode, such as automatic heading mode, automatic position mode, automatic track mode, automatic navigation mode, target tracking mode, etc.;

[0020] 2) Put the control of the main thruster, steering gear, stern thruster and azimuth rudder propeller in the mode of "dynamic positioning control";

[0021] 3) Use position measuring equipment to measure changes in the position of the ship itself;

[0022] a. Select the FUGRO 3100 wide-area differential global satellite positioning system receiver, through the differential signal forwarded by OMNISTAR satellite and INMARSAT satellite, to realize the differential positioning of the ship in the global range, with a positioning accuracy of 1-3 meters and...

Abstract

The present invention relates to ship position keeping technology, aims at solving the special problem of keeping ship position and discloses one kind of dynamic ship position keeping method. The method includes selecting power control system mode, setting the executing mechanism control in 'dynamic position keeping control' mode, acquiring the ship and environment information with the measurement equipment, sending out command with the dynamic ship position keeping control system and keeping the ship position dynamically with the executing mechanisms. The said method can realize fixed point control of ship, automatic heading, automatic tracking navigation, etc. and may be applied widely in military and civil ships with special position keeping requirement.

Description

technical field [0001] The invention relates to ship positioning technology, in particular to a method for ship position control. Background technique [0002] Certain military and civilian special ships, such as ocean research ships, fire fighting ships, and sea supply ships, often have special requirements for ship position control: either require fixed-point position control, or require tracking navigation, or require ships to maintain relative positions with other targets. change, or require automatic tracking of underwater targets, etc. So far, the above special ship position control requirements have not been realized in China. With the development of the navigation industry, there are more and more special requirements for ship position control, which has attracted great attention from relevant parties. Filling the gap of domestic ship dynamic positioning has become a subject that relevant scientific researchers try to overcome. Contents of the invention [0003] ...
