摘要
介绍了一种由８７５１ 单片机控制的高速数据采集系统。该系统的数据采集与存储完全靠硬件实现，其数据采样频率只取决于所选用的Ａ／Ｄ转换器，而不受８７５１ 单片机速度的影响，因而可实现高速数据采集。文中从硬件和软件两方面详细分析了系统的工作原理。
A high speed data acquisition system controlled by 8751 single chip computer is introduced. The data acquisition and storing of the system is fully realized by hardware. The sampling frequency of the system only depends on what A/D convertor is choosed, and has nothing to do with the speed of 8751 single chip computer. So the high speed data acquisition is available. The working principle of the system is analyzed in detail both hardware and software, and some methods of improving the system are presented.
