摘要
本文介绍了基于32位ARM芯片S3C44B0X的微伏信号在线监测系统设计。本设计采用三运放差动放大电路实现了对微伏信号的前置放大;采用μClinux操作系统和MicroWindows图形用户界面实现了数据显示、人机交互和故障自动报警的功能。本设计的应用为实现微伏信号在线监测提供了一种体积小、功耗低、操作灵活的解决方案。
A design of microvolt signal online monitoring system based on 32-bit ARM chip S3C44BOX is introduced in this paper. In this design, a differential amplifier circuit is used for microvolt signal preamplification. To implement the functions of data display, HCI（Human Computer Interaction） and automatic alarming, μClinux operating system and MicroWindows GU1 （Graphical User Interfaces） are also used in this design. This design and application indicates a small size, low power consumption and convenient operation solution to microvolt signal detection and online monitoring.
