Problems solved by technology

However, a fuel quantity sensor can map out a representative oil level height. If the representative oil level height calculated by each fuel quantity sensor is only averaged as the representative oil level height of the fuel tank, the fuel quantity error of the fuel tank will vary with the oil level. increases sharply with increasing angle

Embodiment 1

[0036] The invention proposes a fuel quantity selection processing method based on the oil immersion height of the aircraft fuel quantity sensor, divides each fuel quantity sensor in the fuel tank into seven sections according to the oil immersion height of the aircraft fuel quantity sensor; maps different flight attitudes to After the oil immersion height of the oil quantity sensor is determined, the oil quantity selection processing method is determined according to the combination of different sections for the oil quantity sensors with different oil immersion heights in the same tank;

[0037] If each fuel quantity sensor in the same fuel tank corresponds to a fuel quality characteristic database, then determine the fuel quality characteristic database corresponding to a fuel quantity sensor in the fuel tank as the fuel quality characteristic database of the fuel tank to look up the table to calculate the fuel quantity;

[0038] If all the fuel quantity sensors in the same f...

Embodiment 2

[0042] In this embodiment, on the basis of the above-mentioned embodiment 1, in order to better realize the present invention, further, points A, B, and C are sequentially determined from the bottom to the top of the oil sensor according to the different oil immersion heights of the oil sensor , D, E, and F are six points in total, and according to the six points, the oil quantity sensor is divided into seven sections below A, AB, BC, CD, DE, EF, and above F part;

[0043] The point A is located at the bottom of the fuel tank and is recorded as 0mm, and the point F is located at the top of the fuel tank;

[0044] The oil immersion height difference of the AB section is 20mm, the oil immersion height difference of the AC section is 70mm, that is, the BC section oil immersion height difference is 50mm; the EF section oil immersion height difference is 20mm, and the DF section oil immersion height difference The difference is 70mm, that is, the oil immersion height difference of...

Embodiment 3

[0049] In this embodiment, on the basis of any one of the above-mentioned embodiments 1-2, in order to better realize the present invention, further, when there are m oil quantity sensors in the fuel tank and the oil immersion height detected is in the CD segment;

[0050] If all the fuel quantity sensors correspond to a fuel quality characteristic database, take the average of the oil immersion heights detected by the m fuel quantity sensors as the representative oil level height of the fuel tank, which is used to look up the table to calculate the fuel quantity of the fuel tank;

[0051] If each fuel quantity sensor in the same fuel tank corresponds to a fuel quality characteristic database, the m fuel quantity sensors are used to calculate the corresponding fuel quantity of the table lookup, and then the fuel quantity of the fuel tank is obtained by averaging all the fuel quantity lookup tables;

[0052] The m is greater than 0.

[0053] When the oil immersion height detect...

Abstract

The invention provides an oil quantity selection processing method based on the oil immersion height of aircraft oil quantity sensors. The method comprises the steps: dividing each oil quantity sensorin an oil tank into seven sections according to the oil immersion height of the aircraft oil quantity sensors; mapping different flight attitudes to the oil immersion heights of the oil quantity sensors, and determining an oil quantity selection processing method for the oil quantity sensors with different segment oil immersion heights in the same oil tank according to different segment combinations; if each oil quantity sensor in the same oil tank corresponds to one fuel oil quality characteristic database, determining the fuel oil quality characteristic database corresponding to one oil quantity sensor in the oil tank as the fuel oil quality characteristic database of the oil tank to perform table look-up to calculate the oil quantity; and if all the fuel quantity sensors in the same fuel tank correspond to one fuel quality characteristic database, determining that the characterization fuel level height of the fuel quality characteristic database of the fuel tank is used for subsequent table look-up to calculate the fuel quantity. The invention provides an oil quantity selection processing method capable of covering various flight attitudes of an airplane.

Description

technical field [0001] The invention belongs to the technical field of aviation fuel tank fuel quantity detection, and in particular relates to a fuel quantity selection processing method based on the oil immersion height of an aircraft fuel quantity sensor. Background technique [0002] In the existing aircraft fuel quantity measurement technology, it is necessary to calculate the oil level of the fuel tank and finally use it to query the fuel quality characteristic database to obtain information such as fuel quantity. Since there are multiple oil level sensors in the fuel tank, a virtual sensor is introduced, and the oil level of the virtual sensor is calculated through the oil immersion height and oil level angle of the oil level sensor to represent the oil level of the fuel tank. However, a fuel quantity sensor can map out a representative oil level height. If the representative oil level height calculated by each fuel quantity sensor is only averaged as the representati...
