【摘要】：近年來(lái),隨著物聯(lián)網(wǎng)技術(shù)飛速發(fā)展,物聯(lián)網(wǎng)的應(yīng)用領(lǐng)域越來(lái)越廣泛,因此需要大量的傳感器設(shè)備接入物聯(lián)網(wǎng)中,為物聯(lián)網(wǎng)應(yīng)用的開發(fā)提供所需資源。物聯(lián)網(wǎng)網(wǎng)關(guān)在實(shí)現(xiàn)各類感知層設(shè)備無(wú)縫接入物聯(lián)網(wǎng)中時(shí)起到了重要的橋梁作用。目前,物聯(lián)網(wǎng)網(wǎng)關(guān)仍然存在著一些問(wèn)題:傳感設(shè)備的種類繁多,通信協(xié)議各異,導(dǎo)致設(shè)備接入物聯(lián)網(wǎng)的過(guò)程復(fù)雜。對(duì)于物聯(lián)網(wǎng)應(yīng)用的開發(fā)人員來(lái)說(shuō),缺乏一個(gè)有效的統(tǒng)一的通信協(xié)議框架使得感知層設(shè)備能夠靈活的加入網(wǎng)絡(luò)。為了解決上述問(wèn)題,本文在基于開源硬件平臺(tái)的基礎(chǔ)上,設(shè)計(jì)并實(shí)現(xiàn)了物聯(lián)網(wǎng)網(wǎng)關(guān)中間件的即插即用系統(tǒng)方案。本文首先對(duì)相關(guān)技術(shù)進(jìn)行了深入的研究,主要研究?jī)?nèi)容包括物聯(lián)網(wǎng)網(wǎng)關(guān)中間件、即插即用、Web of Things(WoT)和開源硬件等應(yīng)用技術(shù)�？偨Y(jié)并分析了目前的研究現(xiàn)狀和關(guān)鍵技術(shù)。然后,本文通過(guò)將網(wǎng)關(guān)中間件技術(shù)與AllJoyn通信協(xié)議框架相結(jié)合,提出了兩層結(jié)構(gòu)的網(wǎng)關(guān)架構(gòu),并重點(diǎn)研究了網(wǎng)關(guān)中間件中的即插即用模塊。同時(shí)對(duì)數(shù)據(jù)處理模塊,設(shè)備注冊(cè)模塊,數(shù)據(jù)上傳模塊等進(jìn)行了研究。并結(jié)合Web of Things技術(shù),將設(shè)備資源開放至WoT平臺(tái)。之后,本文介紹了系統(tǒng)主要功能模塊技術(shù)方案與實(shí)現(xiàn)細(xì)節(jié)。最后,本文在實(shí)際環(huán)境中對(duì)系統(tǒng)進(jìn)行部署,并通過(guò)應(yīng)用案例對(duì)系統(tǒng)中設(shè)備的即插即用功能進(jìn)行了驗(yàn)證。
[Abstract]:In recent years, with the rapid development of the Internet of things technology, the application of the Internet of things is becoming more and more extensive. Therefore, a large number of sensor devices are needed to connect to the Internet of things, which provides the necessary resources for the development of Internet of things applications. Internet of things gateways play an important role in realizing seamless access to the Internet of things by various perceptual devices. At present, there are still some problems in the Internet of things gateway: there are many kinds of sensor devices and different communication protocols, which lead to the complexity of the process of accessing the Internet of things. For the developers of the Internet of things, the lack of an effective and uniform communication protocol framework enables the perception layer devices to join the network flexibly. In order to solve the above problems, this paper designs and implements the plug and play system of Internet of things gateway middleware based on open source hardware platform. In this paper, the related technologies are studied, including Internet of things gateway middleware, plug and play Web of things (WoT), open source hardware and other application technologies. The current research situation and key technologies are summarized and analyzed. Then, by combining gateway middleware technology with AllJoyn communication protocol framework, this paper proposes a two-tier gateway architecture, and focuses on the plug and play module in gateway middleware. At the same time, the data processing module, equipment registration module, data upload module were studied. Combined with Web of things technology, the device resources are opened to the WoT platform. After that, this paper introduces the technical scheme and implementation details of the main functional modules of the system. Finally, the system is deployed in a real environment, and the plug and play function of the device in the system is verified by an application case.
