Design And Implementation Of Intelligent Home Gateway Based On ARM

In recent years,with the rapid development of science and technology and constantly improving the people's standard of living,people began to pursue a more comfortable and convenient home lifestyle.For now,although the market has had a lot of smart home products,but these products still have some problems,such as core part of the smart home system is smart home gateway,which is high cost,complicated structure and not compatible with other system,meanwhile it has problems of complicated operation,verbosely remote management and the insecurity of home network.in this context,some scholars and research institutions have started to develop a household management system,which is more intelligent and easy to operate.Based on the above issues and the basis of the current domestic and foreign development status of smart home,the article regards STM32F103ZET6 as hardware platform,which is based on kernel of Cortex-M3,then it regards the uC/OS-III operating system and STemWin as the software platform,then it also combines WiFi communication technology,SX1278 radio frequency communication technology,Ethernet communication technology and 4G technology so that designing a easy operated,easy managerial and cost-effective intelligent home gateway.The gateway uses modular design of the centralized management and decentralized control to solving problems of complex structure,complicated operation and poor scalability.The gateway can through Ethernet or public telephone lines to connect to the Internet so that user can through browser of PC or computer to access to Web server of intelligent home gateway to remotely controlling household or 4G phones to send instruction to the gateway by mobile network,then the home gateway manages indirectly household;meanwhile the gateway through SX1278 build terminal network with intelligent electrical appliances so that realizing centralized management of household;in addition,intelligent home gateway is designed in this paper with the function of the man-machine interface,then the user can through simple man-machine interface to manage household in household.Experiments show that the designed intelligent home gateway can set up internal network,remotely control household equipment,make WiFi communication and real-ize the function of man-machine interface,at the same time show that the gateway has the advantages of simple and practical,what is more,it's cost-effective so that it provides a feasible scheme for smart home gateway later development.
