Abstract EN
In order to intelligently measure the displacement of moving objects, a small displacement measuring system based on MEMS (microelectromechanical system) accelerometer is designed.
Firstly, the principle and error of displacement measurement using acceleration signal are deeply analyzed.
The method of fitting polynomial extremum with better correction effect is selected in the time domain to eliminate the trend term error caused by the DC component, which is the main source of error.
Real-time correction algorithm is added to the time-domain integral of acceleration.
On the hardware circuit, the measurement module, control module, storage module, and power module of the system are designed, respectively.
Finally, the system-integrated packaging scheme is designed, which enables the system to complete the real-time acceleration measurement, velocity and displacement calculation, and data storage of the motion carrier.
Through simulation experiments, it is found that the system has good antioverload capability, and the displacement measurement average accuracy can reach 0.96%, which has very important engineering significance.
