【摘要】:隨著科學技術的發(fā)展,物聯網貫通了當今各種交叉學科與技術前沿,使人與人之間的通信向“人與物”、“物與物”拓展并成為可能,電子與機械、自動控制、現代通信、現代生物、現代材料等技術融為一體。物聯網應用需求廣泛,潛在市場規(guī)模巨大將成為全球新興產業(yè)。我國物聯網技術處于起步階段,在國內大專院校物聯網專業(yè)剛起步,物聯網專業(yè)剛成立高等院校,教材和教學相關設備奇缺,嚴重制約高校物聯網專業(yè)的發(fā)展,物聯網專業(yè)教學的實驗開發(fā)平臺需求不斷增加,市場潛力巨大。論文分析了高校物聯網實驗設備的現狀,解決物聯網實驗開發(fā)平臺中的各種問題。以智能家居作為研究與控制對象,結合Zigbee無線通信技術和嵌入式技術,完成無線傳感器終端節(jié)點與協調器設計,通過嵌入式網關連接Internet實現遠程控制,GSM模塊遠程實時報警,最終完成物聯網智能家居系統(tǒng)實驗開發(fā)平臺設計。第一,結合智能家居系統(tǒng)的特點分析研究Zigbee無線通信技術作為智能家庭通訊組網技術的可行性及Zigbee無線通信技術網絡拓撲結構。第二,采用CC2530作為Zigbee協調器負責家庭網絡的建立、管理、維護,控制終端節(jié)點加入或退出網絡,嵌入式系統(tǒng)PXA270作為網關,GSM模塊實時報警,分別對CC2530無線傳感器網絡系統(tǒng)、PXA270嵌入式系統(tǒng),GSM模塊做了深入研究與設計。第三,深入研究TI公司Zigbee技術與Z-Stack協議棧,對Z-Stack協議進行二次開發(fā),實現無線傳感器網絡協調器與終端節(jié)點軟件設計。第四,完成網關軟件設計,在嵌入式處理器中移植linux操作系統(tǒng),建立嵌入式BOA服務器,實現遠程控制;采用GSM模塊實現系統(tǒng)實時報警。第五,對論文協調器組網功能、終端節(jié)點加入與退出網絡,有障礙物與無障礙物數據傳輸距離,嵌入式網關BOA服務器與遠程控制等進行了測試。經測試,物聯網智能家居教學實驗開發(fā)平臺,各部分功能參數設計均能達到設計要求,完全能滿足物聯網智能家居理論與實踐教學需求。
[Abstract]:With the development of science and technology, the Internet of things (IOT) has made it possible to expand the communication between people to "people and things", "things and things", electronics and machinery, automatic control, modern communication. Modern biology, modern materials and other technologies are integrated. Internet of things needs a wide range of applications, potential market size will become a global emerging industry. The technology of Internet of things in our country is in its infancy. In our country, the major of Internet of things has just started, and the major of Internet of things has just been set up in colleges and universities. The shortage of teaching materials and related equipment has seriously restricted the development of the specialty of Internet of things in colleges and universities. The demand of experimental development platform for Internet of things major teaching is increasing, and the market potential is huge. This paper analyzes the present situation of the experiment equipment of the Internet of things in colleges and universities, and solves the problems in the platform of the experiment development of the Internet of things. Taking smart home as the research and control object, combining Zigbee wireless communication technology and embedded technology, the design of wireless sensor terminal node and coordinator is completed, and the remote real-time alarm of GSM module is realized by connecting Internet with embedded gateway. Finally, the design of the experimental development platform for the intelligent home system of the Internet of things is completed. First, the feasibility of Zigbee wireless communication technology as an intelligent home communication network technology and the network topology of Zigbee wireless communication technology are analyzed and studied in combination with the characteristics of smart home system. Second, CC2530 is used as the Zigbee coordinator to set up, manage, maintain and control the terminal nodes to join or exit the network, and the embedded system PXA270 is used as the gateway to alarm the GSM module in real time. The GSM module of CC2530 wireless sensor network system (PXA270) is studied and designed. Thirdly, the Zigbee technology and Z-Stack protocol stack of TI Company are deeply studied, and the secondary development of Z-Stack protocol is carried out to realize the software design of wireless sensor network coordinator and terminal node. Fourthly, the gateway software is designed, the linux operating system is transplanted into the embedded processor, the embedded BOA server is set up, and the remote control is realized, and the real-time alarm of the system is realized by using the GSM module. Fifthly, the network function of the paper coordinator, the terminal node joining and exiting the network, the distance between obstacle and no obstacle data transmission, the embedded gateway BOA server and the remote control are tested. The test results show that each part of the design of the functional parameters can meet the design requirements and meet the needs of theoretical and practical teaching of the intelligent home in the Internet of things.
