【摘要】 随着我国国民经济的发展，无线传感器网络技术在科学研究、环境监测、日常生活等领域的作用越来越重要。近几年，为填补低速率端无线通信技术的空缺而提出的ZigBee技术由于其功耗低、自愈能力强等特点成为当前研究的热点，可广泛应用于低速无线传感器网络中。在某些无线传感器网路的应用场合，如智能家居，对网络进行延伸或远程监控成为了一种需求，而Internet则是完成这项功能的最佳选择。本文作为整个无线传感器网络系统课题的一部分，设计并实现了以太网接入ZigBee网络的网关系统。在TI公司公开的ZigBee解决方案基础上，分析当今流行的嵌入式Internet技术，综合考虑成本、功能要求等因素，设计了基于ZigBee技术的无线传感器网络网关系统的整体方案。以低功耗、资源丰富的MSP430FG4618单片机为核心，通过网络芯片CS8900A和符合IEEE802．15．4协议的芯片CC2420，分别接入以太网和ZigBee网络，设计并制作了微控制器电路、以太网接入电路、辅助电路和CC2420射频模块。移植精简的嵌入式TCP／IP协议，实现了进行网络通信所需的ARP、IP、ICMP以及TCP协议；研究实现TI提供的ZigBee协议Z-Stack，建立了ZigBee节点。然后对嵌入式TCP／IP协议以及Z-Stack进行协议融合，提出了基于ZigBee技术的无线传感器网络网关的协议模型，即在同一个MCU中实现了两个不同的协议栈，使用嵌入式C语言在应用层编写程序交换报文。论文最后使用VC. net语言编写上位机程序，以Windows套接字方式与网关系统进行通信，验证整个系统的设计方案并给出了调试的结果。测试表明：该方案完成了以太网简单接入ZigBee网络的功能，达到了论文最初设计的要求，也为后面的研究提供了一种新的思路。更多还原

【Abstract】 With the rapid development of our national economy, wireless sensor network is becoming more important in scientific research, environment detection, daily life and so on. In recent years, because of its character of low power consumption, high self-healing ability etc, ZigBee technology, raised for low-rate wireless communication, is widely used in wireless sensor network and becomes a research focus.In some circumstance like smart home, it is a demand to expand network or to monitor the network remotely, and embedded Internet is the best choice. As a part of the whole Wireless Sensor Network System, this paper designed and implemented the gateway between Internet and ZigBee.Based on ZigBee solutions provided by TI company, and analysis of popular embedded Internet technology,taking cost、demand into account,this paper designed a ZigBee based gateway solution:Taking MSP430FG4618 as MCU, connecting Internet and ZigBee network individually through CS8900A and CC2420. MCU circuit、Internet interface circuit、Auxiliary circuit and CC2420 RF module are made. Transplanting embedded Internet, implementing ARP、IP、ICMP、TCP protocols and Z-Stack, This paper also setup a ZigBee node. After analyzing the implementation of TCP/IP and Z-Stack, this paper raised the gateway protocol model of ZigBee based wireless sensor network which mean to run two protocols in one simple MCU, and programmed in embedded C to exchange packet on the application layer.In the end, a process programmed in VC.net in the way of Windows Sock is used to test gateway system’s communication between Internet and ZigBee. Through debug and test, this gateway system could satisfy the requirement, implements the connection between Internet and ZigBee simply and also provides a new idea for the next.更多还原
