Non-self-propelled ship intelligent displacement system and displacement method based on adaptive algorithm

Abstract

The invention relates to a non-self-propulsion ship intelligent moving system and a moving method based on adaptive algorithm. The system comprises a control module and a Global Position System (GPS) module which is connected with the control unit, anchor gears and a frequency converter, wherein the number of the anchors gear is two, the anchor gears are respectively arranged on different positions on the ship, and the anchor gears are respectively connected with independent anchor points through mooring ropes. The method includes the following steps: positioning through the GPS, loading a geodetic coordinate system on construction drawings, moving the ship and other steps. According to the non-self-propulsion ship intelligent moving system and the moving method based on the adaptive algorithm, the real-time positioning information of the GPS module is organically combined with the target position information on the construction drawings, so that the automatic ship moving is achieved, and the motion of the ship can be automatically regulated even the ship is under the load effect of wind, waves and the like and under the influence of the rise and fall of the tide level. The ship moving process of the ship with the system is automatically completed, so that the cost of manpower resource is saved, and the speed and accuracy of the ship moving are improved at the same time.

Description

technical field [0001] The present invention relates to the field of ship positioning and displacement in ocean engineering, and more specifically, to an intelligent displacement system and method for non-self-propelled ships based on an adaptive algorithm. Background technique [0002] Marine projects such as offshore dams, artificial islands, cross-sea bridges, submarine pipelines, etc. require the positioning error of construction ships to be less than 0.5 meters. Power system, so the current offshore construction ships are mostly non-self-propelled ships. However, most of the existing non-self-propelled ship positioning and shifting controls rely on simple manual control devices. The control process requires multiple operators. At the same time, because offshore construction ships are significantly affected by forces such as wind and waves, experienced operators are required in actual operation. According to different working conditions, personnel comprehensively coordi...

However, most of the existing non-self-propelled ship positioning and shifting controls rely on simple manual control devices. The control process requires multiple operators. At the same time, because offshore construction ships are significantly affected by forces such as wind and waves, experienced operators are required in actual operation. Personnel comprehensively coordinate and control the retraction and release of each windlass cable according to different working conditions, and finally realize the positioning and movement of the ship. However, the current manual ship positioning operation method is backward, the manpower demand is large, and the construction speed and accuracy are difficult to guarantee.
