摘要
介绍一种结构简单、精度高、成本低的数据采集装置。它使用简单可靠的硬件高速锁相环电路,控制6通道Σ-ΔA/D转换器,以实现同步整周期采样和跟踪滤波,实现对相互关联的6路信号进行同步数据采集和数据分析。
A kind of data collection apparatus with simple structure,high precision and low cost is introduced in this paper.A simple and reliable hardware phase-locked loop circuit with high speed is used to control 6 channels Σ-ΔA/D converter,realizes the function of synchronous and full period collection and traces filter,synchronously collect the data of the 6 paths signals associated with each other and analyzes the data.
