摘要
介绍了一个用８０３１，ＤＲＡＭ和高速Ａ／Ｄ等芯片构成的快速数据采集系统。该系统使Ａ／Ｄ转换的数据不经ＣＰＵ“中转”，而直接存入ＤＲＡＭ中。它具有硬件结构简单、价格低廉、易实现大容量存储等优点。本系统对模拟信号的采集并将采集数据送入存储器的周期为８μｓ。
A high speed data acquisition system composed of 8031, dynamic RAM (DRAM) and high speed A/D converter, etc, is described. The system possesses the features of simple structure, low cost and large capacity, etc. The cycle time of sampling and storing an analog signal data by using this system is 8 μs.
