Test platform for verifying core control strategy of dynamic positioning system of water platform

Abstract

The invention relates to a test platform for verifying a core control strategy of a dynamic positioning system of a water platform. The test platform comprises an offshore part and a shore base part.The offshore part includes a test carrier, a propeller system, a power system, a measurement system, a data processing and driving system, an offshore wireless communication module, and a remote control receiving module. The shore base part includes a main control system, a monitoring system, a shore-based wireless communication module, and a remote controller. The offshore wireless communicationmodule matches the shore-based wireless communication module; and the remote control receiving module matches the remote controller. According to the invention, the test carrier is an unmanned ship oranother water platform instead of a purely numerical dynamic model; the position, posture and environmental information of the test carrier is collected by the sensor, so that real navigation data can be provided in real time; and the dynamic positioning control strategy function and the performance verification have high authenticity and credibility. The control system is separated from the carrier, so that the control strategy debugging and upgrading become convenient and the verification period of the control strategy is shortened.

Description

technical field [0001] The invention belongs to the field of dynamic positioning system research, in particular to a test platform for verifying the core control strategy of the dynamic positioning system of an unmanned ship or other water platforms. Background technique [0002] With the continuous development of the ocean and the expansion of the deep sea, the traditional mooring system can no longer meet the positioning requirements of deep sea ships and offshore platforms due to its own limitations. The traditional mooring system uses anchor claws to grab the seabed mud to resist external interference to the ship. Its disadvantages are: the positioning accuracy is not enough, and its accuracy is inversely proportional to the water depth; the maneuverability is poor. The process of repositioning anchors is cumbersome; its application is limited by water depth and seabed conditions. The dynamic positioning system overcomes the above shortcomings and gradually develops to ...
