The Plug And Play Technology And System Design Research Of Smart Home

In recent years,with the maturity of various technologies,the Internet of Everything is gradually turning from a concept to a reality,and more and more real-world physical quantities are measured,uploaded and evaluated.As a subset of the Internet of Things,smart home is slowly entering our daily lives.Firstly,this paper introduces the current development status of smart home.And then a centralized home service architecture was proposed,focusing on the heterogeneous communication networks and uneven serviced resources in the smart home field,to meet the requirements of plug-and-play usage with different protocol devices,which can complete intelligent device service discovery,network dynamic expansion and other functions.The main research contents of the thesis are as follows:1)The communication protocols commonly used in the smart home field are discussed,and its data interaction protocol specification is initially studied.It encapsulated the middleware of different communication modules to complete the coding and decoding of different protocols,and completed the interoperability between different protocol devices.2)Dynamic variabilities in the home environment are analyzed,and a set of message formats agreed with the middleware are designed.Through managing the smart devices in the home with these message formats to ensure that the system can accurately record the home in a dynamic environment,ensuring the accuracy of the message.3)Representational State Transfer(REST)is used to implement the architecture with abstracting device entities into a variety of different resources.Then resources and various HTTP methods are grouped to form meta-services which finally satisfying the variety through a combination of several meta-services.Also the service requirements make the software development process as simple as possible.4)Through data mining of the simulated service call log to obtain its frequent sets,the next move of the occupants under the premise of meeting the service needs of the residents is predicted.Provide a viable direction for the intelligence of the home system in the future.The experiment proves that the home service architecture designed in this paper has good interoperability and scalability for different protocols,and can shield the underlying communication protocol well,which reduces the difficulty of data interaction between smart device developers and home suppliers.A hospitable with a smart home environment that is fast,personalized,and has a good living experience is provided.
