Design of Distance Measuring System Based on MEMS Accelerometer
Lei Xu,Liqing Fang,Chunsheng Lin,Deqing Guo,Ziyuan Qi,Ruikun Huo 대한전기학회 2019 Journal of Electrical Engineering & Technology Vol.14 No.4
In order to accurately measure the moving distance of the object and make the distance measurement more intelligent, a distance system is designed based on the Micro Electro-Mechanical System accelerometer. The modular design idea is used to design the three modules of the system, including acceleration measurement module, the acceleration storage module and the acceleration control module. The integrated packaging technology is used to realize the combination of the carrier and the distance system, so that the system can achieve acceleration real-time measurement, storage and other functions on the overload condition. The purpose of real-time calculation of the carrier’s moving distance is realized. And it can upload the stored data to the computer for further analysis and processing. The light gas gun test shows that the system has high anti-overload capability, and it can realize real-time measurement and calculation of motion acceleration. The precision of the distance measuring system can be up to 98.39%.
