Design Of Smart Home System Based On Embedded Linux

With the continuous development of Internet and intelligent hardware,the smart home industry is gradually maturing.At the same time,China's population aging process is accelerating,facing new challenges,China's pension system is still not perfect,people's eyes once again focused on the smart home system.In recent years,the smart home has greatly improved the level of intelligence,a variety of home intelligent robots have been introduced,such as escort robot,window cleaning robot and sweeping robot.Smart home systems are beginning to shift from controlling household appliances to taking care of people's daily lives.In order to realize the coordination between various equipments in the intelligent home system,share information and resources.To achieve compatible home appliances and high-end intelligent products,flexible increase and decrease and change the system of different manufacturers of equipment purposes.In this paper,smart home system is studied,and service-oriented distributed technology is applied to build a distributed architecture of smart home system.In the concrete realization aspect,mainly has carried on the research design from the following four aspects:(1)According to the current situation,future development trend and user's demand of smart home,the solution of intelligent home system is defined,and the hardware structure and software architecture of smart home system are constructed.Among them,the hardware architecture takes ARM and CC2530 as the core,and the software architecture is mainly composed of service-oriented distributed server and ZigBee network.(2)Through the investigation and analysis of the appliance control method currently known,distributed based on the characteristic of ZigBee network and low cost,the realization of home appliance control and Home Furnishing environment information collection work,effectively solve the cable network wiring chains.(3)On the basis of embedded web server,a service-oriented distributed server is constructed.The intelligent device in smart home system is abstracted as service,and the service oriented communication protocol of distributed network is provided.Here,the service is first registered and published in the form of Web Service in the server.(4)The video surveillance system of smart home system is studied.In the aspect ofvideo surveillance,streaming video server is mainly studied.The intelligent home system designed in this paper mainly implements the functions of home appliance control,home environment monitoring,video surveillance,distributed server and intelligent equipment control.The distributed communication network of smart home system is constructed,and the sharing of information and data between devices is realized.The physical function test shows that the system has the characteristics of simple operation,convenient deployment and compatible equipment of different manufacturers.
