Embodiment Construction
[0015] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0016] The invention provides a ship load measurement system, such as figure 1 As shown, it includes host computer unit, radar unit, signal receiving unit and test unit.
[0017] Wherein, the test unit is arranged on the outer side of the ship, including a sleeve, a floating ball and a signal transmitter. The sleeve is a hollow metal cylinder with a top cover and a bottom cover, standing vertically on the water surface on the outer side of the ship, such as figure 2 shown. A number of holes are evenly distributed on the bottom cover and sides to allow water to flow in and out. The floating ball is a metal sphere with a hollow structure, which is fixed inside the sleeve, and the signal transmitter is set inside the floating ball. It should be noted that before the measurement test, it is necessary to adjust the relative fixed position of the float an...

The invention discloses a ship load measuring system which comprises an upper computer unit, a radar unit, a signal receiving unit and a testing unit. The testing unit is arranged on the outer side of a ship and comprises a sleeve, a floating ball and a signal transmitter. The upper computer unit, the radar unit and the signal receiving unit are arranged on the side, where the testing unit is located, inside the ship. The radar unit and the signal receiving unit are in communication connection with the upper computer unit. The specific position of a ship waterline can be obtained by detecting the position of the floating ball in the testing unit, and then the load capacity of the ship can be accurately worked out. In addition, the signal transmitter-receiver and radar modes are adopted for detecting the position of the floating ball in the testing unit, testing data obtained through the signal transmitter-receiver and radar modes is synthesized, testing defects of the signal transmitter-receiver and radar modes are effectively complemented, and therefore the specific position of the ship waterline can be more accurately obtained.
Description
technical field [0001] The invention belongs to the technical field of test and measurement, and in particular relates to the design of a ship load measurement system. Background technique [0002] Ships have a certain upper limit of load, exceeding this limit, the ship will be in danger during navigation. In actual voyages, the relative position of the waterline and the load line is usually used to judge whether the current load capacity of the ship is appropriate. The waterline is the line where the ship meets the water. According to the law of buoyancy, when an object remains at rest in a liquid (without sinking to the bottom or by other external forces), the weight of the water it displaces is equal to its own weight. Therefore, as the load capacity of a ship changes, the position of its waterline will also change. When the load capacity increases, the water line rises; when the load capacity decreases, the water line decreases. The load line is a straight line marked...
