摘　　要：目前使用的烟草交售系统通信结构比较复杂,运行不够稳定。针对这个缺陷,提出将WinCE操作系统移植到ARM9体系结构的主控芯片S3C2410中,实现烟草交售系统的网络节点设计。该方案通过ZigBee无线通讯技术管理所有挂载终端设备,通过以太网实现与控制中心的数据交互,利用RFID(射频识别)技术实现烟农身份识别,提供刷卡确认功能,使用热敏打印机完成票据打印。测试结果表明,基于嵌入式的网络节点结构设计合理,网络节点运行情况稳定,满足烟草交售系统的要求。The communication structure of tobacco acquisition system currently used is very complex, the operation is not stable enough. To this problem, the network nodes for tobacco acquisition system is designed with CPU of $3c2410 embedded proces- sor which has the kernel of ARMg. Windows CE is chosen as the operating system. ZigBee wireless communications technology is used to manage the terminal equipments mounted under the network node. Ethernet is used as the data exchange channel be- tween the network nodes and the control center. RFID （radio frequency identification） is used to obtain the information of the corresponding tobacco farmer. Thermal printer is used to print notes. Field tests show that the stability of the network nodes based on embedded systems is confirmed and the requirements of the acquisition tobacco system are satisfied completely.
