Device and method for measuring the center of gravity of a waterborne vehicle in a moving state

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 water in a moving state. Background technique [0002] The center of gravity measurement technology of waterborne vehicles is crucial to the load and navigation safety of waterborne vehicles. Due to the huge structure and weight of the water carrier itself, it is in a state of continuous swinging, swaying and moving in the water. It is impossible to determine its center of gravity through support methods and suspension methods. , the position of its center of gravity will also change. [0003] The center of gravity of a large waterborne carrier on water is often obtained through an estimated model based on the design model and construction materials during construction. This kind of estimation is only applicable to the position of the center of gravity of the large-scale water ...
