Problems solved by technology

[0003] Existing air pressure sensors usually use one-time calibration for precision calibration during measurement. In the case of large changes in ambient temperature, using the existing calibration method will lead to low measurement accuracy in local areas, resulting in large error in measurement results. Large, affecting user experience

Abstract

Disclosed are a data calibration method and device for an air pressure sensor. The method includes: performing a primary fitting calculation on the nonlinear raw data according to a first preset calibration coefficient to obtain primary calibration data; performing a secondary fitting calculation on the primary calibration data according to a second preset calibration coefficient , to obtain secondary calibration data; determine the secondary calibration data as the air pressure data to be output; output the air pressure data to be output. According to the present disclosure, the data accuracy of the air pressure sensor can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of sensors, and more particularly, to a data calibration method and device for an air pressure sensor. Background technique [0002] The air pressure sensor is mainly used to measure the pressure of the gas. The air pressure sensor is usually used to measure the air pressure, measure the change of the weather, and use the corresponding relationship between the air pressure and the altitude to measure the altitude, etc. [0003] Existing air pressure sensors usually use a one-time calibration method for accuracy calibration during measurement. In the case of large changes in ambient temperature, using the existing calibration method will lead to lower measurement accuracy in local areas, resulting in higher error in measurement results. large, affecting the user experience. [0004] Therefore, the inventor believes that it is necessary to improve at least one of the above problems. SUMMARY OF THE ...
