Abstract

The invention relates to a dynamic positioning semi-physical simulation platform and method, and belongs to the technical field of dynamic positioning. According to the dynamic positioning semi-physical simulation platform, a control computer, a simulation work station and a visual work station are connected to form a local area network by a network exchanger through the Ethernet; a control table is provided with the control computer and conducts instruction control through an operation panel; the visual work station is connected with a projector mechanism which is used for displaying simulation information through a video line. The dynamic positioning semi-physical simulation method comprises the steps that first, the control computer sets a control instruction; second, the simulation work station sets sea state information; third, control software gives out a control instruction of a propeller; fourth, a ship module moves to send ship state information to a sensor module; fifth, the senor module sends the ship state information to the control software, and the information is sent to the visual work station after being processed; six, the visual work station conducts calculation, projection and simulation. The dynamic positioning semi-physical simulation platform and method have the advantages of being convenient to debug, good in simulation effect, capable of greatly lowering the cost of model tests and real ship sea trials and the like.

Description

technical field [0001] The invention belongs to the technical field of dynamic positioning, and in particular relates to a dynamic positioning semi-physical simulation platform and method. Background technique [0002] At present, for offshore engineering vessels and offshore platforms such as large-scale lifting pipe-laying ships, cable-laying ships, dredgers, and three-purpose working ships, the dynamic positioning system has become an indispensable support system for accurate positioning. The system and sensors can continuously detect the deviation between the actual position of the ship or platform and the target position, and then calculate the time required to restore the ship or platform to the target position according to the influence of external wind, waves, currents and other disturbance forces. The direction and size of the thrust, and distribute the thrust to each propeller on the ship or platform, so that each propeller can generate corresponding thrust, so tha...
