【摘要】：為了實現(xiàn)智能家居安防系統(tǒng)的監(jiān)測需求,并解決以往監(jiān)控系統(tǒng)中網(wǎng)關存在的丟包率高、可靠性低和能耗高的問題,設計了一種基于改進UDP協(xié)議的物聯(lián)網(wǎng)網(wǎng)關。首先,設計了以S3C2410為微控制器、DM9000為以太網(wǎng)芯片、EC189為3G模塊和XBEE ZNET為無線通信模塊的網(wǎng)關節(jié)點,然后,定義了MAC層的改進的T-MAC通信協(xié)議和對應的數(shù)據(jù)幀格式,在網(wǎng)絡層設計了一種基于改進LEACH協(xié)議的低功耗分簇路由協(xié)議,在數(shù)據(jù)傳輸層定義了基于改進UDP的協(xié)議以實現(xiàn)數(shù)據(jù)的可靠傳輸,并定義了網(wǎng)關的軟件流程。實驗結果證明設計的網(wǎng)關能實現(xiàn)協(xié)議之間的轉換,具有數(shù)據(jù)丟包率低、可靠性高和能耗低的優(yōu)點,能輔助系統(tǒng)實現(xiàn)室內(nèi)數(shù)據(jù)的實時采集和監(jiān)控,并在數(shù)據(jù)異常時進行報警提示。
[Abstract]:In order to realize the monitoring requirement of smart home security system, and to solve the problems of high packet loss rate, low reliability and high energy consumption, a kind of Internet of things gateway based on improved UDP protocol is designed.Firstly, the gateway node with S3C2410 as microcontroller and Ethernet chip EC189 as 3G module and XBEE ZNET as wireless communication module is designed. Then, the improved T-MAC communication protocol and corresponding data frame format of MAC layer are defined.A low power clustering routing protocol based on improved LEACH protocol is designed in the network layer. In the data transmission layer, the protocol based on improved UDP is defined to achieve reliable data transmission, and the software flow of the gateway is defined.The experimental results show that the gateway can realize the conversion between protocols, which has the advantages of low packet loss rate, high reliability and low energy consumption. It can assist the system to realize the real-time collection and monitoring of indoor data, and alarm and prompt if the data is abnormal.
