与常规的采用中断方式实现定时的数据采集系统不同,本文着重介绍一种以笔记本电脑为主控机,采用I/O传输方式,用8253和EPROM芯片构成可变采样率实时数据采样系统,最小采样率为20μs,具有采样速率高工作稳定可靠、实用等特点。
Different from the conventional data acquisition system that uses interrupts to achieve timing, this paper focuses on a real-time data sampling system with variable sampling rate composed of 8253 and EPROM chips with I / O transmission mode, Sampling rate of 20μs, with a high sampling rate stable and reliable, practical and so on.
