Dynamic positioning and dynamic tracking model test system for drag suction dredger

Abstract

The invention relates to a dynamic positioning and dynamic tracking model test system for a drag suction dredger, which belongs to the technical field of dredging engineering and oceaneering, and is characterized by including an industrial personal computer, a wireless Ethernet switch, an image position measuring system, an NI control computer and an actuator, wherein the signal output end of the image position measuring system is connected with the industrial personal computer; the industrial personal computer transmits control instructions to the NI control computer through the wireless Ethernet switch; and the NI control computer is connected with and used for controlling the actuator, and drives a model to restore to a target position. The dynamic positioning and dynamic tracking model test system has the advantages of simple structure, convenience for operation, wide application range and the like, and can be used for effectively detecting the configuration of a thrust system of the dynamic positioning and dynamic tracking model test system for the drag suction dredger, control precision, effectiveness of the system and the correctness and rationality of the design of a working environment.

Description

technical field [0001] The invention belongs to the technical field of dredging engineering and marine engineering, in particular to a dynamic positioning and dynamic tracking model test system for a trailing suction dredger. Background technique [0002] At present, with the development of the dredging industry, the market is becoming wider and wider, and the demand for accurate and efficient dredging is becoming more and more urgent. The dynamic positioning and dynamic tracking system of a trailing suction dredger means that the ship can continuously detect the deviation between the actual position of the drag head and the target position without the help of the mooring system, and calculate the ship's arrival or return to the target position by overcoming external interference through the controller. The size of the thrust and thrust torque required by the target position, and then the thrust distribution system makes each thruster respond accordingly, so that the drag he...
