The Design And Research Of Energy-saving Smart Home System Based On Arduino Due

With the rapid development of the global economy,people’s daily quality of life requirements also increased.The smart home system that changes the way of human life follows the rapid development of computer technology,network technology,control technology and artificial intelligence.Smart home is the home which uses the traditional home with the function of live as a platform.The home uses the network communications technology,automatic control technology,audio and video surveillance technology and many other high-tech to integrate electrical equipment related to daily life on the mobile client to build an efficient,safe and convenient way of life.At the same time,the energy management system is added to smart home to achieve a green living environment.Therefore,this article designs and researches a energy-saving smart home system based on Arduino Due.After describing the general concept of smart home and its development status,this article based on the current demand for smart home determines the overall program for the whole smart home.Energy-saving smart socket and energy harvesting system constitute the energy management system.Network communication mode selects WIFI communication.Mobile phone control terminal system is Android system.The controller’s control panel is the Arduino development board.On hardware,the system uses Arduino Due as the control core,and extends the general module,energy management module,security module,sub-controller module.the article focuses on the energy management module,the module is divided into energy-efficient smart socket and energy acquisition.Energy-efficient smart socket includes power conversion circuit which uses LNK625 DG power supply chip and energy metering module which uses HLW8012 energy metering chip.Energy acquisition includes power generation module,power management module and energy storage module.In terms of software,software system of this article is based on WIFI communication and serial communication,uses Arduino programming for intelligent devices and Android programming for mobile as branches.The intelligent device and the WIFI module interact with each other through serial communication.WIFI module,cloud server and mobile phone App report and send instruction through WIFIcommunication.Arduino program is mainly to complete monitoring the status of intelligent devices,updating the status of data,identifying serial communication instruction.Android program mainly to complete controlling interface,getting smart device status,sending control instructions.At last,the final work is to jointly debug hardware modules and software modules.The purpose is to test the compatibility and compatibility between modules.After testing,the module is basically completed the expected function,and the system design is successful.
