Liquid level sensor, container, aircraft and liquid level detection method

Abstract

The invention provides a liquid level sensor, a container, an aircraft and a liquid level detection method, and relates to the technical field of test. The liquid level sensor comprises a liquid leveldetection device and an operation processing device, wherein the liquid level detection device comprises three detection probe mechanisms, the three detection probe mechanisms are arranged in an equilateral triangle, information of three liquid level heights in the container are acquired by the three detection probe mechanisms, and the operation processing device is used for determining a dip angle of an installation surface of the three detection probe mechanisms in the container relative to a horizontal surface and liquid level height information of the container according to the information of the three liquid level heights and installation positions of the three detection probe mechanisms. According to the liquid level sensor, the container, the aircraft and the liquid level detectionmethod, provided by the invention, a measurement error of the container at different positions can be compensated, dip angle information of the container can be accurately improved, the liquid levelsensor is simple in structure, high in reliability and high in installation freedom, accurately-measured and high-accuracy liquid level information can be acquired.

Description

technical field [0001] The present disclosure relates to the technical field of testing, and in particular to a liquid level sensor, a container, an aircraft and a liquid level detection method. Background technique [0002] At present, a liquid level sensor is usually used to detect the liquid level in the container. The container can be a fuel tank or a fuel tank of an aircraft, an automobile, etc., and the liquid level sensor is a capacitive liquid level sensor or the like. At present, when the container is horizontal, the detection value of the liquid level sensor is more accurate, but when the attitude of the container changes, the detection value of the liquid level sensor is less accurate. For example, when the aircraft is in level flight, the liquid level information of the fuel in the fuel tank measured by the liquid level sensor is accurate information, but when the flight attitude changes, the liquid level information of the fuel in the fuel tank measured by the l...

Problems solved by technology

For example, when the aircraft is in level flight, the liquid level information of the fuel in the fuel tank measured by the liquid level sensor is accurate information, but when the flight attitude changes, the liquid level information of the fuel in the fuel tank measured by the liquid level sensor It cannot accurately reflect the actual oil volume of the fuel tank, and inaccurate liquid level information will lead to wrong judgments on the health status of the engine system
