摘　　要：介绍了一种以ARM9微控制器为核心的多路数据采集系统。该系统的硬件部分采用SAMSUNG公司的S3C2440A微控制器,以及TI公司24Bit精度的ADS1271A/D转换芯片。软件部分采用了Linux作为嵌入式操作系统,在此基础上选用图形化编程语言Qt完成应用程序的设计。系统实现了最高采样率为每秒50000采样点,18Bit分辨率的4通道数据实时采集,可以满足目前绝大多数应用场合的需求。A multi-channel data acquisition system based on ARM9 mierocontroller was introduced. Its hardware adopts the S3C2440A microcontroller manufactured by SAMSUNG corporation, the ADS1271 A/D chip produced by TI corporation, its software uses Linux as its embedded operating system. Graphical programming language Qt is chosen to complete the application design. This system can reach the highest sampling rate of 50 000 samples per second, and can achieve 4-channel real-time data collection of 18 Bit resolution. This system can meet the needs of vast application.
