The System Design And Implementation Of Smart Home Control Terminal Based On Linux

As tech has rapidly impacted the environment to live in, it is a trend to becomesmart and widespread in ecosystem of home. Smart home is gradually changingpeople’s life and people are able to complete the appliances control、informationacquisition、security control through the smart home control terminal. This paperfocuses on the research of smart home control terminal.This paper accomplishes the basic functions based on the embedded linux osincluding appliances control、security cotrol、information control、enviroment controland home monitor.The hardware platform of smart home control terminal system makes use of theS3C2440based on ARM9IP CORE as the CPU，meanwhile the software platform ofsmart home control terminal system uses the embedded linux as the os. The smart homecontrol terminal system is composed of the motherboard and the daughterboard. And themotherboard is a common development board including S3C2440acted as CPU, whilesome devices are on the daughterboard such as air-condition、fan、door and so on. Themotherboard communicates with the daughterboard with wired method.The embedded system adopts the Qt/Embedded as the GUI and the softwaredesigned and implemented in this paper is bases on the the embedded QT.The paper has the following contents:1. Does the research on the requirements analysis and the overall frameworkdesign, and then selects the software/hardware platform of smart home control terminal,at last completes the overall hardware architecture and software architecture includingsoftware platform and the application running on the platform.2. Builds the hardware platform of smart home control terminal system includingthe design of the important interface circuits such as network module、memory module、GPRS module and so on.3. Builds the software platform of smart home control terminal including theembedded system’s transplant、the root filesystem’s making、transplanting based on QT/E and the development of drive and application.4. Designs and implements the application of smart home control terminal. Thedesign part is comprised of the selection of the software arch mod and the modelingusing UML, the other is completed along with the successive level including the user’sGUI、authentication level、the control center level and the functional level.5. Verifies if it is reasonable and practicable through testing this software using theblack-box testing、the white-box testing、the system testing and pressure test.
