摘要
开发出一种便携式车辆加速度信号采集系统。以嵌入式E-Box为主控单元,以MEMS三轴加速度传感器为传感单元,自主开发信号调理电路板和基于LabVIEW的上位机软件。该系统可实现车辆低频运动加速度和高频振动加速度信号的快速采集、调理、记录和显示。系统小巧便携,可大量采集数据。实验表明:该系统稳定可靠,能准确监测车辆加速度状态。
A portable vehicle acceleration signal acquisition system is developed.E-Box,an embedded computer,is taken as the main control unit.3-axis acceleration sensor's selected as sensing units.The signal conditioning circuit,and the software of upper computer within the LabVIEW environment are developed.By using this system,the low-frequency motion acceleration and high-frequency vibration acceleration signals could be collected,processed,recorded and displayed quickly.The system is small sized and portable and can collect large quantities of datas.The test result shows that the system is stable and reliable,and can monitor the vehicle acceleration status accurately.
