Problems solved by technology

This method has certain defects. If all electronic scales have a deviation in one direction, there will be an accumulation of errors, which may cause the indicated value to exceed the required deviation range when these electronic scales are used together.

Embodiment Construction

[0028] Such as figure 1 As shown, the embodiment takes an aircraft as an example to further describe the present invention in detail. The aircraft is composed of 3 landing gears, and 3 electronic scales need to be combined when the aircraft is weighed. In the system accuracy verification, we use these three electronic scales to form an aircraft weighing instrument to verify the system accuracy.

[0029] A method for detecting the accuracy of an aircraft weighing instrument system, comprising a standard device 1, the standard device 1 includes a support frame with multiple legs 2 and a flat plate fixed above the support frame, and the number of legs 2 of the support frame is connected with an electronic scale connected in series The quantity is the same, and the specific method includes the following steps:

[0030] Step 1: Connect multiple electronic scales in series to form the aircraft weighing instrument 4, and place it on a level ground;

[0031] Step 2: Place each leg 2...

Abstract

The invention provides a method for detecting the precision of an aircraft weighing instrument system. The precision of the whole aircraft weighing instrument system is detected by using an etalon. The etalon comprises a multi-supporting-leg supporting frame and a flat plate fixed above the supporting frame. Different standard forces are sequentially applied to the center of the flat plate, the weight value displayed by the airplane weighing instrument at present is measured, and the system indicating value precision of the airplane weighing instrument is finally obtained according to the calculated relative indicating value error q and the calculated relative indicating value repeatability b.

Description

technical field [0001] The invention relates to the technical field of measurement and detection, and relates to a detection method for the precision of a combined electronic scale system used in aircraft weighing. Background technique [0002] As a means of transportation in the air, in order to ensure its safe and reliable flight, the weight and center of gravity of the aircraft need to be within a reasonable range. The method to obtain its weight and center of gravity is to weigh the aircraft. At present, there are many methods for weighing an aircraft, and the common method is to use an aircraft weighing instrument to weigh it. [0003] The aircraft weighing instrument is different from other electronic scales. The aircraft weighing instrument connects the data of multiple electronic scales, and finally can superimpose a total weight obtained by each electronic scale, that is, the weight of the aircraft. When weighing, the landing gear of the aircraft is placed on each ...
