摘要
针对国内物流行业现状,结合嵌入式应用技术,设计了应用于电子订货系统的嵌入式EOS终端.该终端以PHILIPS公司的ARM微处理器LPC2210为核心,外扩了外部静态存储器IS61LV25616AL和FLASH存储器SST39VF160,使用了专用的键盘控制芯片ZLG7290和看门狗监控芯片SP708S,采用SMG240128A点阵图型液晶作为显示模块,扩展了SD卡和UART/MODEM通信接口,最后在硬件基础上进行了应用软件的开发.该EOS终端采用了模块化设计,体积小,功能强,可采用有线PSTN和无线GPRS两种通信方式,具有很好的应用前景.
In view of the present situation of logistics industry, combined with embedded technology, this paper introduces the design and implementation of the embedded EOS terminal which is used in electronic ordering system. The terminal uses LPC2210, produced by PHILIPS, as the core microprocessor, external SRAM SST39VF160 and Flash memory IS61LV25616AL, adopts the specific keyboard control chip ZLG7290 and supervisor chip SP708S, expands the SD card and UART/MODEM communication interface, then, develops the application software. The terminal adopts the modular-design method. Not only is it of small size and high performance, but it can communicate with PSTN cable and GPRS terminal,which makes it have a good application prospect.
