Semi-physical simulation system of dynamic positioning ship

Abstract

The invention relates to a semi-physical simulation system of a dynamic positioning ship. According to the semi-physical simulation system of the dynamic positioning ship, ship movement is simulated on land, and detailed experimental verification is carried out on devices before the devices are shipped, so that reliability of a system is ensured after the system is shipped. The semi-physical simulation system of the dynamic positioning ship comprises a simulation computer, a 1# data processing module, a 1# control module, a 2# data processing module, a 2# control module and a semi-physical system, wherein the semi-physical system is composed of a three-freedom-degree simulation experiment platform, a six-freedom-degree movement device, a sensor module and a data receiver, the sensor module comprises a GPS module, a compass and an MRU, the sensor module is installed on the six-freedom-degree movement device, and the three-freedom-degree simulation experiment platform is installed on the six-freedom-degree movement device. The semi-physical simulation system of the dynamic positioning ship is used for simulating a dynamic positioning system of the surface ship through combination of the platform, a swing platform material object, a six-freedom-degree ship mathematical model and an environmental model so that experimental verification of the devices can be achieved before the devices are shipped.

Description

technical field [0001] The invention relates to a semi-physical simulation system of a dynamic positioning ship which can ensure the reliability of the system after the system is shipped by simulating the movement of the ship on land and performing detailed experimental verification on the equipment before loading the ship. Background technique [0002] With the rapid development of the global economy, energy consumption is increasing. After a hundred years of exploitation, the oil resources on land have begun to show a downward trend in the amount of exploitation, so people have turned their attention to the ocean, which is richer in resources. With the development of industries such as offshore oil development, technologies related to ship control have attracted more and more attention from researchers, especially the Dynamic Positioning System (DPS), which has been widely used in offshore oil development, pipe laying, laying cables, submersible rescue and lifesaving oper...
