【摘要】：近些年随着科技的迅猛发展及人民生活水平的提高,人们对家居产品的要求越来越高端化,智能化,这就给以嵌入式技术为基础的智能家居系列产品的研发带来了新一波的发展浪潮。智能家居的核心是家庭自动化,利用嵌入式技术,将控制芯片嵌入到各种家居设备中,目标是利用一个中央处理设备来控制所有的设备,并可以通过许多因素变化来进行智能化识别。我国的研究人员在智能家居领域取得了不菲的成绩,相关的技术已经渗透到了人们的日常生活中。但是,目前市场上的智能家居产品还存在着一些问题。第一,单个终端设备的发展并不能代表智能家居的整体繁荣,多个设备之间的交互组成的互联网络才是智能家居发展的最终目标;第二,目前市场上的智能家居产品大多使用声控、光控等低级的方式,在实际应用中还远远达不到智能的水平;第三,目前智能家居行业的信息安全意识薄弱,隐私信息并没有得到有效的保护,有可能造成严重的安全隐患。种种这些都不利于良好的用户体验的形成。本文针对这些问题做了一些深入的研究并取得了一定的成效。首先,针对智能化家居生活中缺乏统一接入方式的问题,创新性的提出了一种兼容蓝牙Mesh的分布式星形网架构设计,且设计并实现了集WiFi、蓝牙、语音通道为一体的多通道的网关系统;其次,将基于隐马尔可夫模型的语音关键词识别技术嵌入到智能家居产品中,使得机器可以识别人类发出的相关指令并予以执行,使得产品更加的智能化;再次,针对物联网中的安全问题,提出了一个轻量级的安全秘钥认证协议,保证信息传输中消息的安全性。实验效果表明,本文提出的整套网关系统的基本功能良好,可以满足用户对智能家居产品的需求,为提高人民的生活质量做出了一些贡献。
[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.
