【摘要】：為了實(shí)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(guān)存在的丟包率高、可靠性低和能耗高的問題,設(shè)計(jì)了一種基于改進(jìn)UDP協(xié)議的物聯(lián)網(wǎng)網(wǎng)關(guān)。首先,設(shè)計(jì)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(guān)節(jié)點(diǎn),然后,定義了MAC層的改進(jìn)的T-MAC通信協(xié)議和對(duì)應(yīng)的數(shù)據(jù)幀格式,在網(wǎng)絡(luò)層設(shè)計(jì)了一種基于改進(jìn)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(jìn)UDP的協(xié)議以實(shí)現(xiàn)數(shù)據(jù)的可靠傳輸,并定義了網(wǎng)關(guān)的軟件流程。實(shí)驗(yàn)結(jié)果證明設(shè)計(jì)的網(wǎng)關(guān)能實(shí)現(xiàn)協(xié)議之間的轉(zhuǎn)換,具有數(shù)據(jù)丟包率低、可靠性高和能耗低的優(yōu)點(diǎn),能輔助系統(tǒng)實(shí)現(xiàn)室內(nèi)數(shù)據(jù)的實(shí)時(shí)采集和監(jiān)控,并在數(shù)據(jù)異常時(shí)進(jìn)行報(bào)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.
