【摘要】：一種技術(shù)的進(jìn)步往往能催生出另外一些技術(shù)的產(chǎn)生與發(fā)展，近些年隨著信息技術(shù)、網(wǎng)絡(luò)技術(shù)以及其他各種短距離無線技術(shù)的發(fā)展，以及人們在實(shí)際生活中面對一些需要通信的問題時(shí)，迫切希望有一種應(yīng)用能力極強(qiáng)、能耗低且組網(wǎng)方便的無線通信技術(shù)滿足應(yīng)用需求，Zigbee技術(shù)就是在這樣一種背景下產(chǎn)生的，而隨著它的發(fā)展和應(yīng)用不斷廣泛，將它融合到當(dāng)前使用最為廣泛的Internet中來已是大勢所趨。現(xiàn)如今Zigbee與傳感器技術(shù)結(jié)合起來形成了應(yīng)用廣泛的無線傳感器網(wǎng)絡(luò)技術(shù)。據(jù)一些媒體透露，WSN被認(rèn)為對人類未來的生活產(chǎn)生影響最大的一種無線網(wǎng)絡(luò)通信技術(shù)，其在國防、環(huán)境監(jiān)測及預(yù)報(bào)、各種智能化產(chǎn)品和工業(yè)生產(chǎn)制造等領(lǐng)域有著廣闊的應(yīng)用前景。 本文提出了“基于Zigbee與Internet的接入技術(shù)研究”一文，它結(jié)合Zigbee無線傳感器網(wǎng)絡(luò)技術(shù)、嵌入式技術(shù)和無線接入技術(shù)，將Zigbee無線傳感器網(wǎng)絡(luò)與當(dāng)前大眾所熟悉的Internet結(jié)合起來，使無線傳感器網(wǎng)絡(luò)采集到的數(shù)據(jù)能實(shí)時(shí)準(zhǔn)確的傳送到計(jì)算機(jī)或者其他Internet的智能終端上，完成Zigbee與Internet的雙向無線接入。并針對目前在本課題的研究上存在的問題提出增強(qiáng)系統(tǒng)安全系數(shù)的身份認(rèn)證機(jī)制,通過身份認(rèn)證機(jī)制確認(rèn)用戶的合法性，從何保證數(shù)據(jù)不至于被非法登錄網(wǎng)絡(luò)對數(shù)據(jù)進(jìn)行盜取、非法改變等，實(shí)現(xiàn)無線傳感器網(wǎng)絡(luò)與Internet的安全有效融合。 文中選取TI公司的cc2530無線射頻芯片作為Zigbee無線網(wǎng)絡(luò)核心部件，基于ARM9體系結(jié)構(gòu)的s3c2440處理器作為兩種網(wǎng)絡(luò)轉(zhuǎn)換的核心網(wǎng)絡(luò)轉(zhuǎn)換中心，pc機(jī)作為Internet端接收控制設(shè)備，研制了一套完整的嵌入式網(wǎng)絡(luò)轉(zhuǎn)換服務(wù)器。在完成系統(tǒng)硬件平臺(tái)的搭建后，通過Zigbee終端節(jié)點(diǎn)上的傳感器采集各種待檢信號，利用高性能的cc2530無線收發(fā)芯片將采集的信號聚攏到協(xié)調(diào)器中的存儲(chǔ)單元中，通過Zigbee協(xié)議棧將采集到的數(shù)據(jù)打包為Zigbee格式并在處理器中轉(zhuǎn)換為Ip數(shù)據(jù)包，并建立Ip地址與Zigbee網(wǎng)絡(luò)短地址進(jìn)行一一映射，，以確定發(fā)送目的，而在Linux與Internet上的終端建立socket通信。經(jīng)處理器處理后的數(shù)據(jù)送入嵌有TCP/IP協(xié)議棧的USB無線網(wǎng)卡對進(jìn)行以太網(wǎng)封裝，然后通過無線網(wǎng)卡發(fā)送到Internet上的終端，或者Zigbee網(wǎng)絡(luò)節(jié)點(diǎn)接收控制命令并作出響應(yīng)，并利用Linux-PAM模塊完成用戶的登錄認(rèn)證，確保用戶的合法登錄，保證Zigbee網(wǎng)絡(luò)數(shù)據(jù)的安全使用，從而實(shí)現(xiàn)Zigbee無線傳感器網(wǎng)絡(luò)與Internet的無縫融合。 最后進(jìn)行系統(tǒng)檢測，以溫度信號為待測信號檢測Internet上接收Zigbee數(shù)據(jù)情況和Zigbee節(jié)點(diǎn)接收控制命令情況，并針對結(jié)果作出分析。
[Abstract]:Advances in one technology often lead to the emergence and development of other technologies. In recent years, with the development of information technology, network technology and other short-range wireless technologies, And when people are faced with some problems that need communication in real life, they are eager to have a wireless communication technology with very strong application ability, low energy consumption and convenient networking to meet the application requirements. Zigbee technology is produced under such a background. With the development and application of it, it is the trend to integrate it into the most widely used Internet. Now Zigbee combines with sensor technology to form a widely used wireless sensor network technology. According to some media, WSN is regarded as a wireless network communication technology which has the greatest impact on the future life of human beings. It has broad application prospects in the fields of national defense, environmental monitoring and forecasting, various intelligent products and industrial production and manufacturing. In this paper, the research of access technology based on Zigbee and Internet is presented. It combines Zigbee wireless sensor network technology, embedded technology and wireless access technology, and combines Zigbee wireless sensor network with Internet, which is familiar to the public at present. The data collected by wireless sensor network can be transmitted to computer or other intelligent terminals of Internet in real time, and the two-way wireless access between Zigbee and Internet can be completed. And in view of the problems existing in the research of this subject at present, this paper proposes an identity authentication mechanism to enhance the safety factor of the system, to confirm the legitimacy of the user through the identity authentication mechanism, and to ensure that the data will not be stolen by the illegal login network. Illegal changes, the realization of wireless sensor networks and Internet security and effective integration. In this paper, the cc2530 RF chip of TI Company is chosen as the core component of Zigbee wireless network, and the s3c2440 processor based on ARM9 architecture is used as the core network conversion center of two network conversions. A complete set of embedded network conversion server is developed. After building the hardware platform of the system, the sensors on the Zigbee terminal node are used to collect all kinds of signals to be detected, and the collected signals are gathered into the memory unit of the coordinator by using the high performance cc2530 wireless transceiver chip. Through the Zigbee protocol stack, the collected data is packaged into Zigbee format and converted into IP packets in the processor, and the IP address and the short address of Zigbee network are set up to map one by one to determine the sending purpose, and the socket communication is established between socket and the terminal on the Internet. The data processed by the processor is sent to the USB wireless card embedded with TCP / IP protocol stack for Ethernet encapsulation, then sent to the terminal on the Internet through the wireless network card, or the Zigbee network node receives the control command and responds to it. The Linux-PAM module is used to complete the login authentication of users, to ensure the legitimate login of users, to ensure the safe use of Zigbee network data, and to realize the seamless integration of Zigbee wireless sensor network and Internet. Finally, the temperature signal is used as the signal to detect the situation of receiving Zigbee data on the Internet and the Zigbee node to receive the control command, and the results are analyzed.
