摘要
该文采用加速度传感器MMA8452Q对水表振动状态进行检测,采用频域分析方法,以快速傅里叶变换为工具对振动特征频率和振动位移进行求解,采用低功耗器件以及中断编程方式实现装置的低功耗设计,基本完成了一款低功耗的水表振动状态检测装置的设计。
This paper focuses on detecting the vibration state of the water meter by the MMA8452Q accelerometer.With the way of the frequency domain analysis method,the fast Fourier transform is used to solve the vibrationcharacteristic frequency and the vibration displacement.Low power devices and the interrupt programmingmethod are adopted to realize the low power of the device.A low-power water meter vibration state detectiondevice design ared basically completed.
