【摘要】：近些年隨著科技的迅猛發(fā)展及人民生活水平的提高,人們對(duì)家居產(chǎn)品的要求越來越高端化,智能化,這就給以嵌入式技術(shù)為基礎(chǔ)的智能家居系列產(chǎn)品的研發(fā)帶來了新一波的發(fā)展浪潮。智能家居的核心是家庭自動(dòng)化,利用嵌入式技術(shù),將控制芯片嵌入到各種家居設(shè)備中,目標(biāo)是利用一個(gè)中央處理設(shè)備來控制所有的設(shè)備,并可以通過許多因素變化來進(jìn)行智能化識(shí)別。我國(guó)的研究人員在智能家居領(lǐng)域取得了不菲的成績(jī),相關(guān)的技術(shù)已經(jīng)滲透到了人們的日常生活中。但是,目前市場(chǎng)上的智能家居產(chǎn)品還存在著一些問題。第一,單個(gè)終端設(shè)備的發(fā)展并不能代表智能家居的整體繁榮,多個(gè)設(shè)備之間的交互組成的互聯(lián)網(wǎng)絡(luò)才是智能家居發(fā)展的最終目標(biāo);第二,目前市場(chǎng)上的智能家居產(chǎn)品大多使用聲控、光控等低級(jí)的方式,在實(shí)際應(yīng)用中還遠(yuǎn)遠(yuǎn)達(dá)不到智能的水平;第三,目前智能家居行業(yè)的信息安全意識(shí)薄弱,隱私信息并沒有得到有效的保護(hù),有可能造成嚴(yán)重的安全隱患。種種這些都不利于良好的用戶體驗(yàn)的形成。本文針對(duì)這些問題做了一些深入的研究并取得了一定的成效。首先,針對(duì)智能化家居生活中缺乏統(tǒng)一接入方式的問題,創(chuàng)新性的提出了一種兼容藍(lán)牙Mesh的分布式星形網(wǎng)架構(gòu)設(shè)計(jì),且設(shè)計(jì)并實(shí)現(xiàn)了集WiFi、藍(lán)牙、語(yǔ)音通道為一體的多通道的網(wǎng)關(guān)系統(tǒng);其次,將基于隱馬爾可夫模型的語(yǔ)音關(guān)鍵詞識(shí)別技術(shù)嵌入到智能家居產(chǎn)品中,使得機(jī)器可以識(shí)別人類發(fā)出的相關(guān)指令并予以執(zhí)行,使得產(chǎn)品更加的智能化;再次,針對(duì)物聯(lián)網(wǎng)中的安全問題,提出了一個(gè)輕量級(jí)的安全秘鑰認(rèn)證協(xié)議,保證信息傳輸中消息的安全性。實(shí)驗(yàn)效果表明,本文提出的整套網(wǎng)關(guān)系統(tǒng)的基本功能良好,可以滿足用戶對(duì)智能家居產(chǎn)品的需求,為提高人民的生活質(zhì)量做出了一些貢獻(xiàn)。
[Abstract]:In recent years, with the rapid development of science and technology and the improvement of people's living standards, people's demand for household products is becoming more and more high-end and intelligent. This brings a new wave of development of smart home products based on embedded technology. The core of smart home is home automation. With embedded technology, the control chip is embedded into all kinds of home devices. The goal is to use a central processing device to control all devices and to identify them intelligently by changing many factors. Our researchers have achieved a lot in the field of smart home. Related technologies have penetrated into people's daily lives. However, there are still some problems with smart home products on the market. First, the development of single terminal devices does not represent the overall prosperity of smart home. The final goal of the development of smart home is the Internet composed of the interaction between multiple devices. Second, most of the smart home products on the market currently use low-level methods such as voice control, optical control and so on. Third, the information security awareness of the smart home industry is weak, privacy information has not been effectively protected. All these are not conducive to the formation of a good user experience. This paper has done some in-depth research on these problems and achieved certain results. Aiming at the lack of unified access mode in intelligent home life, a distributed star network architecture compatible with Bluetooth Mesh is proposed, and a multi-channel gateway system with WiFi. Bluetooth and voice channels is designed and implemented. Secondly, the technology of speech keyword recognition based on hidden Markov model is embedded into smart home product, so that the machine can recognize and execute the relevant instructions issued by human beings, and make the product more intelligent. Aiming at the security problems in the Internet of things, a lightweight security secret key authentication protocol is proposed to ensure the security of messages in information transmission. The experimental results show that the basic functions of the whole gateway system proposed in this paper are good. It can meet the needs of smart home products and contribute to the improvement of people's quality of life.
