基于ADIS16355的汽车驾驶操作信号采集系统

摘要

This paper studied a new signal acquisition system of vehicle driving operation,which based on MEMS sensors. When the output analog signals came from the MEMS sensor , sampling them into digital signals and processed them with DSP and using the method of differential measurement,the system could get the value of attitude angles with high precision. The configuration and software design of system were discussed .The feasibility of system was proved by tests. The result showed that it could meet the requirements of accuracy of vehicle driving attitude measurement. It was a practical measurement system.%研究开发了一种基于集成微机电系统(MEMS)传感器的新型汽车驾驶操作信号采集系统.该系统通过对MEMS传感器的输出信号进行A/D采样,获得相应的数字信号,并将其送进DSP进行处理.运用差分测量方法,实现对汽车驾驶姿态角的高精度测量.阐述了系统的硬件组成和软件设计,并通过实验对系统进行了可行性验证.实验结果表明,此测量系统能够满足汽车驾驶姿态测量的精度要求,是确实可行的测量系统.
