Arduino-based Intelligent Cloud Housekeeper Design And Development

The concept of smart home,which has been rapidly developed especially in some developed countries such as Europe and the United States,was proposed in 1990 s.However,in recent years,the research on the smart home system,especially its architecture,is slightly stagnant.The mainstream smart home system at home and abroad almost uses the ad hoc network architecture based on the middle control host that it is difficult to realize intelligent and automatic control due to the lack of intelligence and scalability.The mode with the characteristic of plug-and-play,assembly and disassembly cannot be achieved in machinery component,which leads to low flexibility.As far as the application program interface is concerned,each vendor does not contact each other and is committed to developing their own standards,which causes that all kinds of smart home system hardware and software at the market can hardly be compatible.And in terms of basic characteristics,it does not rely on the huge data of the Internet,which makes the intelligent experience based on big data mining cannot be realized.In this paper,the mainstream smart home architecture is deeply studied and analyzed,and a new cloud-based smart home architecture,based on which a set of smart cloud housekeeper system is implemented,has been proposed.The smart home system based on cloud platform,whose hardware communication adopts the unified protocol based on content,uses the ZigBee Ad hoc network model and star network topology structure,which makes the scalability qualitatively improved.In order to reduce the code redundancy in the Web and Android,a set of the same JSON communication format is shared in the access terminal.Besides,in terms of data forwarding in the back-end architecture,a highly efficient distributed middleware is designed to achieve load balancing and recovery mechanism for downtime.More importantly,in data processing,A cloud-based intelligent logic is defined,which not only speeds up the reaction speed,but also improves the system throughput.In addition,in terms of intelligent expansion,a web crawler to automatically extract Web content is implemented to provide users with the latest Internet data.And then,how to use the system to build an intelligent air conditioning with a fully automatic operation is described by showing an example.At last,the paper is summarized and the personal prospect for the development of smart home system is described.
