摘　　要：针对传统数据采集系统采集精度与数据处理能力的不足,结合当前广泛应用的嵌入式系统技术和总线技术,基于ARM9处理器S3C2440设计了一种分散式数据采集系统。底层数据采集系统采用了模块化的设计结构,各模块采用统一的总线把数据传送给主控器;最后系统利用ARM9强大的数据处理能力对所有数据进行分析、处理。实际试验证明,该系统数据处理速度快、控制精度高,可满足一般工业现场的要求。Aiming at the shortages of traditional data acquisition system in collecting accuracy and data processing capability,the distributed data acquisition system based on ARM9 processor S3C2440 has been designed.In the design,the widely applied embedded system technology and bus technology are included.The data acquisition system at the bottom level is in modular structural design;data from each module are sent to main controller via unified bus;then all the data are analyzed and processed in the system by adopting ARM9 that offering powerful data processing capability.The practical experiment verifies that the system features rapid data processing function,high control accuracy to meet the requirements of general industrial fields.
