基于嵌入式系统ZigBee网与互联网网关设计

Design of Gateway Based on Embedded System between WSN ZigBee and Internet

为实现互联网与无线传感网络ZigBee互通,提出了一种基于嵌入式系统网关设计方案。介绍了ZigBee与TCP/IP协议的分层结构及作用,网关硬件以TI AM335X与CC2530F256芯片为核心组成,模块间以串口进行通讯。在网关中TCP/IP与ZigBee协议的解析由各自模块实现,网关通信采用C/S结构,通过串口实现在应用层互联网信息与ZigBee信息交互。该方案具有实现结构简单、对用户透明,但无线传感网络规模受限。

A gateway design based on embedded system is presented for interconnection between WSN Zigbee and Internet. ZigBee and TCP / IP protocol hierarchical structure and function are described in this paper. The gateway hardware is composed of two module that include TIAM335X and CC2530F256 used as core chip respectively, communicating by serial port. Analysis of TCP/IP and ZigBee protocol implement by each module in the gateway, which using C/S architecture for communication,Information exchange between Internet and WSN ZigBee is realized on the application layer by serial port。The proposed gateway has the advantage of the simple structure, transparent to the user, but restrictions on the wireless sensor network size。
