基于ARM7和LabVIEW的岩土工程多路数据采集系统设计

Abstract

该文利用ArM7 S3C44b0处理器为核心并辅以必要的外围电路作为下位机进行多路数据采集,上位机采用lAbVIEW软件设计应用程序进行数据采集控制、数据处理、曲线显示、数据保存等操作,上、下位机基于自定义的通信协议通过rS-485互联,实现岩土工程多路数据采集系统。

This paper uses S3C44B0 processor and other necessary periphery circuit as the lower computer for multi-channel data acquisition,adopting LabVIEW software design the application program as the upper computer for data acquisition control,data processing,curve displaying and data storage.The upper and lower computer interconnect through RS-485 based on the custom communication protocol,realizing a multi-channel data acquisition system in geotechnical engineering.
