Abstract

The invention relates to a dynamic positioning and dynamic tracking system of a drag suction dredger and a control method thereof, which belong to the technical field of engineering ship automation. The dynamic positioning and dynamic tracking system of the drag suction dredger comprises a control panel, a programmable logic controller, a heading measurement device, a position measurement device, a wind direction and wind speed measurement device, a ship motion attitude measurement device, a propeller and a steering engine, wherein the control panel is connected with and controls the programmable logic controller, the heading measurement device, the position measurement device, the wind direction and wind speed measurement device, the ship motion attitude measurement device, the propeller and the steering engine. The positioning and dynamic tracking control method aims to detect actual positions and target positions, actual motion directions and target directions of the drag suction dredger and a drag head, controls a thruster on the dredger so as to enable the dredger to be kept at required positions and headings, and accurately controls dredging operation. The dynamic positioning and dynamic tracking system and the control method thereof have the advantages of simple structure, convenience in operation, accurate control, multiple modes, high dredging efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of engineering ship automation, in particular to a dynamic positioning and dynamic tracking system and a control method for a trailing suction dredger. Background technique [0002] At present, with the rapid development of economic globalization, the scale of port channel construction, land reclamation, river and lake regulation and other projects is getting larger and larger, and the requirements for construction period are getting higher and higher. How to improve the dredging efficiency of dredgers becomes more urgent. The existing trailing suction dredger power does not have a positioning and dynamic tracking system, and it is impossible to control the position and trajectory of the trailing suction dredger or the drag head, which greatly reduces the efficiency and accuracy of dredging operations, and becomes a major problem in trench digging and backfilling operations. , Digging tunnels and other tech...
