Design And Implementation Of Smart Home Control Module Based On Cortex-A9

As the internet is deeply integrated into the people’s lives and the strategy of "Internet+" is further advancing,the new era of the smart-home is coming.How to let people to have a safe,convenient,comfortable and smarthome life is becoming the future development trend.At that time,even if users are not at home,they can also control the dynamic situation at any time.Combined with computer,network communication,automatic control and embedded technology,smarthome control system can realize remote control on home security control system,lighting system,curtains,gas detection system,and so on.This paper analyzes and studies the present situation and development trend of domestic and foreign intelligent home control system.The key technologies include: embedded technology,sensor technology,Wi Fi technology and Android technology.This paper adopts the structure of Cortex-A9 series Exynos4412 processor as the core controller,Boa fixed server was builtand placed in the indoor,the mobile client software was placed in hand.The mobile person by virtue of its own mobile client software,using a wired or wireless APP,could monitor and control his remote indoor appliances,and other equipment real-time.Through the Web browser or via mobile phone APP access indoor server,the user could implement real-time lighting switch,electric curtain pulling,accident alarm,video screen monitoring.Intelligent home control module design and implementation could improve and enrich people’s material life and spiritual life.Dissertation,mainly completed the following content: 1.The demand analysis of smart home control module and the key technology research,on the basis of demand analysis,complete based on ARMCortex-A9 as the core of the controller hardware and software architecture analysis and design.2.Research development Board selection problem,the paper analyzes the key module,complete the intelligent household system for the extension of the hardware circuit design,including the stepper motor,relay control,and the human body infrared induction control hardware interface design,etc.3.Completed the construction of the smart home control module software platform,including the Boot Loader burning and configure,compile the Linux kernel and configuration,creation and configuration of the root file system and the establishment of embedded Web server and video streaming server configuration,device drivers are written,the application of writing and the Android client interface design and the design and implementation of a smart home APP.4.Complete the function of the system hardware and software testing,the system test can meet the design requirements.The smart home control module in this dissertationhas certain extensibility.Through the corresponding hardware and software testing,we find that this system meets the demanding of the real-time performance,versatility and low power of intelligent control.It canachieve connectivity with the controlled equipment and transmissionof control signals.People could use the mobile phones and other terminal devices to achieve the remote control for cameras real-time monitoring,human body infrared induction alarm,lighting system and curtains control.Deployment of the system is convenient,cost is low,the smart home and embedded applications,and other fields have a wide application prospects.
