摘　　要：为了实现对信号的高精度测量,以ADS1158和dsPIC30f4011为基础设计了16位高精度数据采集系统方案。给出了系统硬件结构图以及主要电路模块的设计思路,并介绍了系统软件的结构与主要程序流程以及如何在此硬件基础之上将系统快速升级为24位数据采集系统的方案。该数据采集系统可以广泛的应用于传感器信号采集、工业控制等场合中,具有非常好的市场应用前景,其设计也具有很强的参考价值。To achieve the high-precise measurement of signal, a high acquisition 16-bit data collection system based on ADSl158 and disPIC3Of4011 is designed. The paper gives a description of the hardware structure of system and the design ideas of main circuit modules, followed by the introduction of the software structure of system, major procedure and the method of fast upgrading the current system based on hardware to 24-bit data acquisition system. The data acquisition system can be widely ap-plied to many areas, such as sensor signal acquisition and industrial control. The design has great reference value and good mar-ket prospects.
