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, and transmit the ground differential signal through the OMNISTAR satellite and the INMARSAT satellite to realize the differential positioning of the ship on a global scale, with a positioning accuracy of 1-...

Abstract

The present invention relates to a ship positioning technology, solves the special positioning problem of ships, and discloses a ship dynamic positioning method. The method selects a dynamic control system to be in a desired mode, executing mechanisms are controlled to be in the ''dynamic positioning control'' mode, the ship information and environment information are collected by using measuringequipment, a dynamic positioning control system gives a command, and dynamic positioning of the ship is realized through the executing mechanisms. By applying the method, ships can perform fixed-pointposition controlling, automatic bowing, automatic tracking navigation, automatic tracking of underwater targets and the like, and the ship dynamic positioning method can be widely applied to specialmilitary and civilian vessels with special positioning requirements.

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] ...
