Load weighing method, load weighing device, load weighing system and flight equipment

Abstract

The invention provides a load weighing method, a load weighing device, a load weighing system and flight equipment. The weighing system comprises a first weighing component, a second weighing component and a processor. The first weighing part is provided with a first bearing surface and is used for bearing a load on the flight equipment and measuring first pressure of the load at the current moment of flight of the flight equipment; the second weighing part is provided with a second bearing surface used for bearing the standard substance and measuring the second pressure of the standard substance at the current moment. The first bearing surface and the second bearing surface are in the same plane. The processor is connected with the first weighing part and the second weighing part and comprises an acquisition module and a calculation module, the acquisition module is used for acquiring the first pressure and the second pressure, and the calculation module is used for calculating the weight and / or mass of the load according to the first pressure and the second pressure. According to the invention, the load can be accurately weighed, and the hardware cost and the computing power cost are reduced.

Description

technical field [0001] The present application relates to the technical field of flight equipment, in particular to a load weighing method, a weighing device, a weighing system and flight equipment. Background technique [0002] During the flight of flying equipment such as drones or manned aircraft, loads such as medicine tanks, fuel tanks or fertilizer tanks are usually weighed in real time to determine the residual amount of the load. The weighing component used to weigh the load can usually accurately calculate the weight and / or mass of the load only when the bearing surface used to carry the load is parallel to the horizontal plane (the horizontal plane is perpendicular to the direction of the acceleration of gravity). [0003] However, since the flight attitude of the flight equipment changes all the time during the flight, it is difficult for the bearing surface used to carry the load to remain parallel to the horizontal plane, which makes it difficult to accurately w...

Problems solved by technology

[0003] However, since the flight attitude of the flight equipment changes all the time during the flight, it is difficult to keep the load-bearing surface parallel to the horizontal plane all the time, which makes it difficult to accurately weigh the load directly using the weighing components
