摘要
在实际工程应用中,为了得到较为准确的运动分量信息,通常采用陀螺仪和加速度计作为惯测组件传感器。本文基于串行外设接口对微机电系统陀螺仪和微机电系统加速度计的角速度、加速度、温度等原始数据进行多通道采集和存储,利用数字信号处理器和大规模现场可编程门阵列将数据读取后通过串口上传至上位机实时显示。经验证,该方法采集数据准确可靠,扩展性强,具有较高的工程应用价值。
In practical engineering applications,in order to obtain more accurate motion component information,gyroscopes and accelerometers are usually used as inertial measurement component sensors.This paper studies the multi-channel acquisition and storage of the angular velocity,acceleration,temperature and other raw data of the Micro-Electro-Mechanical System(MEMS)gyroscope and MEMS accelerometer based on the Serial Peripheral Interface(SPI),utilize Digital Signal Processor(DSP)and Large-scale Field-Programmable Gate Array(FPGA)to read the data and upload it to the host computer for real-time display through the serial port.It has been verified that this method is accurate,reliable,and scalable,and has high engineering application value.
