单片机控制的一种新型高速数据采集方法

High speed Data Collecting Method Controlled by Single Chip Computer

本文提出了一种实用的新型高速数据采集的实现方案,可实现采样速度从10MH_z～20MH_z的数据采集,由单片机实现控制管理,A/D转换器件用最普通的AD0809,利用某些信号具有重复性的特点,用硬件搭出高速部分,分时地对信号进行采样,从而实现对整个信号的采集。

This paper presents on available method of high speed data collecting. The date collecting system is controlled by single chip computer,and the sample rate is 10 MHz to 20mHz. The common element AD0809 is used as A/D converter.Based on the repetition of certain signals, the high speed device is made up with herdware. Sampling the signals separately .the whole signas collecting can be achived.
