Abstract

The invention provides a device for measuring the gravity center of a waterborne carrier in a motion state. The device is characterized by being provided with four or more GNSS signal receiving devices, a posture sensor device and a CPU data recording and processing device, wherein the GNSS signal receiving devices are used for receiving a GNSS satellite signal in real time, and calculating the geographic coordinates of an observing point; two of the GNSS signal receiving devices are arranged in the heading direction of the waterborne carrier; the posture sensor device is used for acquiring the posture values of rolling, pitching and heaving of the waterborne carrier in real time; and the CPU data recording and processing device is connected with each GNSS signal receiving device and the posture sensor, and used for recording the observing value of each device in real time, and processing the observation values to obtain the coordinates of the gravity center of the waterborne carrier under a waterborne carrier coordinate system. Through adoption of the device and method for measuring the gravity center of the waterborne carrier, the gravity center position of the waterborne carriercan be obtained accurately in real time specific to the problems of irrationality and inaccuracy of an existing waterborne carrier gravity center determining method.

Description

Technical field [0001] The invention relates to the field of center of gravity measurement, in particular to a device and method for measuring the center of gravity of a large-scale water carrier on the water in a sports state. Background technique [0002] The measurement technology of the center of gravity of the waterborne vehicle is very important for the weight and navigation safety of the waterborne vehicle. Due to the huge structure and weight of the water carrier itself, it is in a state of continuous swing, shaking and movement in the water. It is impossible to determine its center of gravity through the support method and the suspension method, and changes with its own cargo configuration and the supplement and consumption of fuel and fresh water , Its center of gravity will also change. [0003] The center of gravity of large-scale waterborne vehicles on the water is often obtained through estimation models based on the design model and construction materials during con...
