摘要
传统的基于单片机的数据采集终端在对所采集数据的实时显示分析方面需要额外的PC支持,不具备便携性。设计出基于嵌入式技术的无线网络传输数据采集终端。该终端采用S3C2410处理器,支持大屏幕LCD显示,移植支持无线网络的最新Linux内核,实现了Linux2.6下基于SPI接口的A/D驱动,并提供接口给上层Qt应用程序。应用表明,该终端界面友好,便携性好,运行稳定,具有良好的可扩充性,具有很好的推广价值。
The real time display of data collected by traditional data collecting terminal based on SCM needs the additional support of PC, so its not portable. This paper designs a data collecting terminal with wireless-transporting support based on embedded-teeh. S3C2410 CPU is used, and the latest Linux kernel is ported in this terminal. It supports large screen LCD display. Also a Linux2.6 driver for .ADC with SPI interface is programmed to support up- layer Qt applications. The portable terminal shows a user-friendly interface. It runs stably and can be extended easily and of great generalize value.
