摘要
提出一种基于ARM920T内核的ARM9芯片S3C2440的无线物流终端机方案。系统充分利用S3C2440的片内资源,通过串行通信方式扩展各个应用模块,包括RFID读写器、GPS、GPRS/CDMA等。软件采用嵌入式Linux操作系统作为系统软件。该终端机实用、方便、快捷,解决了传统的有线连接和数据要在远端处理的不足。
This article proves a logistics wireless terminal machine based on core ARM920T of chip ARM9 S3C2440. The system makes the best use of the inner Source of chip S3C2440, extended each application module through COM, which include RAM RFID, GPS,GPRS/CDMA. The system software used embedded Linux operation system. So the terminal machine solved the problem that the traditional wire connection and the data must be processed in remote places, which is convenient, fast and practical.
