Problems solved by technology

Large surface ships have a large shape, and a bubble-rich layer is formed on the bottom of the ship during navigation. As the speed of the ship changes, the bubble layer is free on the bottom of the ship, and the speed measurement is prone to fluctuations, which brings great difficulties and challenges to real-time, accurate and stable speed measurement.

Abstract

The invention discloses a speed information fusion method, comprising: 1) Measuring point layout: a plurality of speed measuring points are arranged in a triangle on the ship, and each speed measuring point is equipped with a sensor and an amplifier; 2) Data collection: using the sensor and the amplifier to obtain speed information , using the navigation system to obtain the speed and heading of the stern shaft; 3) Data fusion: based on the ship's navigation status, the data obtained in step 2) are fused and calculated to obtain the ship's speed; where the ship's navigation status is obtained through the speed information, the speed of the stern shaft and Heading can be judged. The speed fusion method provided by the present invention not only considers the reliability of the measured value but also considers the influence of the ship's operating state on the speed measurement, so that the final speed obtained is more accurate and stable.

Description

technical field [0001] The invention relates to the technical field of speed measurement of large surface ships, and more specifically relates to a speed information fusion method. Background technique [0002] Aircraft take-off and landing of large surface ships is a basic operation. When the aircraft takes off and lands, the speed of the ship is the basic element, so there are high requirements for the real-time performance, accuracy and stability of the speed. Large surface ships have a large shape, and a bubble-rich layer is formed on the bottom of the ship during navigation. As the speed of the ship changes, the bubble layer is free on the bottom of the ship, and the speed measurement is prone to fluctuations, which brings great difficulties and challenges to real-time, accurate and stable speed measurement. [0003] Therefore, how to improve the accuracy of speed measurement of large surface ships is an urgent problem to be solved by those skilled in the art. Content...
