摘要
从商品展示系统的现状和需求出发,深入研究采用嵌入式技术和射频识别技术的商品展示屏整体结构。提出了基于RFID、ARM9微处理器、以太网通信、触摸屏技术的智慧型展示屏设计方案。系统采用NXP公司的HITAG S无源电子标签,以及相对应的射频芯片HTRC11001T构建RFID模块电路;采用三星公司的32位微处理器S3C2440A为主控芯片,外扩存储器、语音电路、通信模块、触摸屏模块。阐述了系统总体设计,以及微处理器与相应硬件模块的接口设计。
In view of the current situation and demands of the goods display system, a deep study of overall architecture of goods display screen is made based on embedded technology and RFID technology. A design of smart display screen is put forward based on RFID, microprocessor ARM9, Ethernet communication, and touch screen technology. To build RFID module circuit, NXP company＇s HITAG S passive RFID tags, and the corresponding RF chip HTRCll001T are used. Samsung company＇s 32-bit microprocessor chip S3C2440A is utilized as master control chip. Memory, voice circuits, communication module, touch screen module are expanded. The overall design of the system is described, as well as the interface design of the microprocessor and the corresponding hardware module .
