The Research of the Performance of the Tilt Based on ADXL213

SONG Guo-bin;YUAN Lue-lue;College of Communication and Information Engineering,Nanjing University of Posts & Telecommunication;  
Inclinometer is an equipment which measures changes of tilt angle of the object varies with time. It has wide range of applications,mainly used in railways,construction,military,industrial automation and many other sophisticated areas. It is an important part of the crustal deformation observation instrument,which has been widely used in the measurement of ground tilt as well as the detection and warning of geological disasters. However,the directly output data of tilt angle based on ADXL213 has poor static and dynamic characteristics and stability and its fluctuation is relatively large. Therefore we have to perform a filtering process on the output data,and the frequency of data output should meet industrial requirements. In addition,the calculation of angle occupies large amount of the processing resource which leads to low output frequency. In order tackle this problem,we exchange the time with space and finally meet the industrial requirement.
