基于ARM的振动传感器幅频特性测试系统研究
An Arm Based Amplitude.Frequency Characteristic Test System for the Vibration Sensor
摘要
Abstract
A central control process unit with ARM as its core is designed in order to implement the amplitude-frequency characteristic test system for the vibration sensor. Output channel 1 of the D/A of the ARM can generate a frequency-adjustable sine signal, while output channel 2 control the variable gain amplifier circuit. Thus the amplitude of the vibration sensoris output signal will be in the working range. Then full period sampling is done to the output signal,using A/D of the ARM. Finally Goertzel algorithm is used to detect the amplitude of signal. The accuracy and effectiven-Ess of this system is verified by the experiment results.关键词
