【摘要】 为了解决以往高速数据采集板或仪器存在数据采集速度与存贮容量之间的矛盾，本文提出一种高速大容量数据采集方法，介绍了其实现系统设计思想、硬件原理及软件设计。该系统采样时钟为1MHz，12位A／D转换，数据存贮速度可变，最高为3M字节／秒（每个数据点3个字节），存贮容量由系统机硬盘空间决定。更多还原

【Abstract】 A way of high-speed and huge-capacity data acquisition is proposed in this article in order to solve the contradiction between speed and capacity which existed in high-speed data acquisition board or instrument formerly. And the idea of design, the principle of hardware and the design of software are all introduced. The sampling frequency of the system is 1MHz and the analog -to- digtal conversion is 12bits. The speed of date store can be changed. The fastest speed is 3Mbyte/s (every data point includes three bytes). The memory capacity is desided by hard disk of system computer.更多还原
