Calibration method of MEMS accelerometer is mainly use high precision turntable turning experiment in the gravitational field

by acquiring and storing output of accelerometer in different positions and solve scale factor and zero voltage of accelerometer to be calibrated using post-processing method. However

the efficiency of post-processing method is low

data processing is complicated. In order to optimize the calibration system and improve the calibration efficiency

put forward and design a MEMS accelerometer fast online calibration system

use the microcontroller to real-time acquire accelerometer data in different position

process and transmit to the host computer which designed by Lab VIEW software

Finally

real-time and fast fit the calibration curves and calibration parameters

the system has a certain application value.
