摘要
无线振动传感器使用三轴MEMS加速度计ADXL357作为传感模块检测振动加速度,ADXL357由于其内部工作原理,需进行标定,通过标定来降低各项误差以提高其检测精度。本文采用六位标定法对传感器进行标定,根据ADXL357自身内部物理量的转换关系,对振动数据进行处理,再将得到的加速度数据进行分解,最终得到较为精确的加速度序列。
The wireless vibration sensor uses the three-axis MEMS accelerometer ADXL357 as the sensing module to detect vibration acceleration.Due to its internal working principle,the ADXL357 needs to be calibrated,and the calibration is used to reduce various errors and accordingly improve its detection accuracy.This article uses the six-digit calibration method to calibrate the sensor.According to the conversion relationship of the internal physical quantity of the ADXL357,the vibration data is processed,and then the acceleration data obtained is decomposed,and finally a more accurate acceleration sequence is obtained.
