Design And Implementation Of Intelligent Home System Based On Internet Of Things

With the improvement of people's living conditions,people generally start to care about the comfort of their living environment.Driven by the Internet of things technology,the development of smart home is showing a rapid and vigorous development trend,and the commercial value behind it will be an important nuggets of national economic development in the future.Smart home system is a safe,intelligent,energy-saving and comfortable living environment by applying various sensors,bus technology and communication technology.This paper fully studies the domestic and foreign development status of smart home,some domestic smart home system platform are analyzed,they have in common is that through the wireless sensor network for environmental information collection,and through the home gateway to process the data will be collected after uploaded to the cloud platform through wireless communication technology,users via mobile devices access cloud platform to check the indoor environment,and work through the application software to control the intelligent terminal.In order to improve the data processing ability of smart home,intelligent security control,data acquisition and friendly man-machine interaction ability,this article also are introduced on the basis of the traditional smart home facial recognition technology and voice interaction technology,improve the ability of intelligent household security and the man-machine dialogue,in order to improve the function of smart home control system.In this paper,sensors such as temperature and humidity sensor,humidity sensor,smoke sensor,camera and voice module are adopted to collect environmental information,and the working status of household appliances and curtains is controlled by relay module and curtain control module.The sensor part and the control part adopt wireless sensor network node to collect and control the data information.Since there are many sensors and control devices in the room,data sending and receiving is mainly realized through intelligent gateway.The indoor part is realized through ZigBee wireless communication technology.The data uploading part adopts WiFi communication technology to upload.In order to improve the indoor security ability,the face recognition function is added on the original basis to strengthen the identification ability of the household.The system also adds a voice module,which facilitates the voice interaction between human and machine and improves the interestingness of the smart home system.
