Design And Implementation Of Multi-channel Bluetooth Gateway

In recent years,with the rapid development of technology and the improvement of people's living standard,People's demand for the Home Furnishing product requires more and more high-end,intelligent,which brought a wave of development of a new wave of research and development with embedded technology based intelligent Home Furnishing series products.Intelligent home automation is the core of Home Furnishing.With the embedded technology,the control chip is embedded into various Home Furnishing equipment,aiming to control all devices using a central processing equipment,and can achieve intelligent identification by changing many factors.Researchers in our country have made a lot of achievements in the field of smart home,the relevant technology has penetrated into people's daily lives.However,there are still some problems in the market of smart home products.First,the development of single terminal equipment can not represent the overall prosperity of the internet intelligent Home Furnishing,interaction between multiple devices is the ultimate goal of intelligent Home Furnishing development;second,most of the intelligent Home Furnishing products on the market use sound and light controlled low-level way in practical application is far from intelligent.Third,the current level of awareness of information security in intelligent Home Furnishing industry is weak,and there is no effective information privacy protection,which may cause serious security risks.All these are not conducive to the formation of a good user experience.In this paper,we do some in-depth research on these problems and get some results.First of all,aiming at the problem of lacking of terminal equipment Home Furnishing,we design and implement the gateway system whit multi channel,WiFi,Bluetooth,voice channel as a whole;secondly,based on the hidden Markov model of speech keyword recognition technology and embedded into intelligent Home Furnishing products,the relevant instructions identify human issued and implement it Are more intelligent;thirdly,aiming at the safety problem of the IOT,we proposes a lightweight security key authentication protocol which can secure message transmission of information.The experimental results show that the basic function of the gateway system proposed in this paper is good,which can meet the needs of the users of smart home products,and make some contributions to improve the quality of life of the people.
