摘要
介绍基于嵌入式计算机系统的数据采集系统的设计和实现,该系统由硬件和软件两部分组成。硬件采用基于ARMv5te、XScale构架的嵌入式微处理器PXA270芯片,软件采用嵌入式操作系统Linux。与传统的数据采集系统相比,此系统具有集成度高、组合灵活、更好的可靠性和实时性,目前已经用于400 km/h高速综合检测列车上应答器的数据采集,同时本系统也可以应用于实时图像监控等复杂系统中。
This article described the design and implementation of Data Acquisition System based on Embedded Computer System.The System consisted of hardware and software.The hardware used embedded microprocessor architecture based on ARMv5te,XScale PXA270,and the software used an embedded operating system Linux.Compared with traditional Data Acquisition Systems,this System had the advantage of higher integrity level,more combination of flexible,better reliability and real-time performance,has been used in the high-speed train detective system for the transponder data collection,and at the same time,the System could also be used in real-time image monitoring of complex systems.
