摘 要
随着信息领域各种技术的发展，在数据采集方面的技术也取得了长足的进步，采集数据的信息化是目前社会发展的主流方向。各种工业领域都用到了数据采集，在石油勘探、地震数据采集等领域已经得到广泛应用。随着测控技术的迅猛发展，以嵌入式计算机为核心的数据采集系统己经在测控领域中占到了统治地位。数据采集系统是将现场的各种参数如温度、压力、频率等进行采集后送微机进行处理和分析，达到检测和控制的目的。
本文介绍了一个比较小型的多变量数据采集系统的硬件设计。采用MCS-51单片机为主要控制器件，扩展程序存储器EPROM、数据存储器RAM，扩展A/D转换芯片0809和D/A转换芯片0832以及其它外围电路来实现本设计的功能。

As the field of information technologies in development, in the technical aspects of data collection has also made great progress, collecting data and information is the mainstream social development direction. Various industrial fields to use the data acquisition, in oil exploration, seismic data acquisition, and other fields has been widely used. With the rapid development of monitoring and control technologies to embedded computer as the core data acquisition system has been accounted for in the monitoring and control in the area of the dominant position. Data Acquisition System is the scene of various parameters such as temperature, pressure, frequency of collection for evacuation Computer processing and analysis, detection and control to achieve the objective.
In this paper, a relatively small number of variable data acquisition system hardware design. MCS-51 microcontroller used as the main control device, the expansion program memory EPROM, data storage RAM, expansion o
