可编程高速采集卡的设计

Design of Programmable and High Speed Collection Card

本文介绍了一种可编程采集卡的设计方法,能够随意切换模拟开关,使AD转换器对多通道模拟信号进行任意采样,从而实现采集系统可灵活编程。本文通过分析传统的多通道模拟信号的采集系统电路的特点,介绍了多通道可编程采集卡的总体设计方案及其原理,并详细描述了各个模块之间的状态关系和工作时序。

this paper introduces the design method of high speed collection and coding card ,which can be switched the simulation switch at random, it also can sampling randomly to multi-channel analog signals by A/D converter. In this paper, we analyse the characteristic of the traditional collection card, which processes of multi-channel analog signal, introducing the principle and design project of the collection card, describing the relation of each module and scheduling of module in detail.
