Smart Home Products Based On ARM+ONENET Cloud Platform

Paper studies the application of ONENET cloud platform in smart home,and emphasizes the openness,practicability and extensibility of ONENET cloud platform in this field.In view of the difficulty in realizing interconnection and business collaboration among smart products,which affects the user experience needs,the concept of "smart" in smart home can not be closely adhered to.This paper chooses STM32F1 series development boards as intelligent gateway access cloud platform,Linux + QT system development business application layer,and designs a smart home product with strong expansibility and wide compatibility.The data interaction between device layer and ONENET cloud is realized,and the control function of business application layer is completed,which provides theoretical and practical support for the transition from smart home to AI stage.In this paper,the requirements of product design are presented,and the overall design scheme of smart home is given.In hardware,the device layer intelligent gateway is constructed in the form of "core + peripheral".STM32F103ZET6 is used as the core processor to run UCOSII real-time operating system.The hardware has DM9000 Ethernet circuit and peripheral has a variety of communication protocol circuits.The device layer electronic control board establishes hardware connection with the intelligent gateway equipment through RS232 communication interface.Business application layer uses Cortex-A8 series S5PV210 development board.The core board includes four DDR SDRAMs with 1GB memory and 2G NAND FLASH.The bottom board includes some basic peripherals.USB WIFI network card(MTK7601)is selected to realize wireless network communication of the development board.In software,device layer realizes intelligent gateway docking ONENET cloud platform,data point upload cloud platform and data storage(&forwarding)function;in business application layer,transplanting Linux operating system includes U-boot transplantation,kernel transplantation,root file system production and image burning.Transplant wireless network card driver,transplant RESTful API project,through RESTful API to achieve equipment addition,deletion and command download function to achieve business application layer control home electronic control board.The product designed in this paper has been verified and tested for various functions.The results show that the product guarantees practicability and sense of experience.All functions can be realized and meet the basic needs of users.Intelligent gateway access to ONENET cloud platform,business application layer command control board,equipment layer and cloud platform information exchange makes smart home products step out of the intelligent single product stage,steady development into the interconnection stage and transition to the artificial intelligence stage.Intelligent gateway has an open communication interface to realize the connection of electronic control boards with different communication protocols.Multi-device layer access to ONENET cloud platform can realize data interoperability,scene interconnection and compatibility.
