摘要
文章介绍了一种基于ZigBee协议的无线传感器网络的网关设计整体方案。以Intel PXA270为核心处理器,处理器通过以太网接入芯片、GPRS模块、符合IEEE802.15.4协议的CC2430射频芯片,分别接入以太网、GPRS网络和无线传感器网络。移植精简的嵌入式TCP/IP协议,分析Z-Stack协议栈,实现两种网络信息的报文转换,同时实现无线传感网络与GPRS网络的信息传输,设计并制作了基于ZigBee的无线传感器网络网关系统。
This paper describes the overall design of a gateway program based on the ZigBee wireless sensor network protocol. Intel PXA270 is the eore processor, it could access chip through Ethernet. GPRS module, cc2430 radio chip which accord with the IEEE802. 15. 4 agreement, respectively connected to the Ethenet. GPRS network and wireless sensor net work. Transplant streamlined embedded TCP/IP protocol analyzes the Z-Stack protocol stack, implement the packet conversion between two kinds of network information. And achieve the information transmission in the wireless sensor network and the GPRS network, designed and produces gateway system based on the ZigBee wireless sensor network.
