Design And Implementation Of The Multifunctional Intelligent Control Terminal System Based On Cortex-A8 Architecture And Linux Operation System

With the pace of development in today’s world speeding up, people have higher requirements for the efficiency of their life, especially on aspects of shortcut, synchronization, security and so on. Thus, the multifunctional intelligent control terminal system emerges, with it’s convenient, efficient and remote controllable features. It could solve problems in people’s life well and make people’s life more colorful!Through researching and analyzing the current domestic and international research status of intelligent control terminal, this paper puts forward a design scheme of a multifunctional intelligent control terminal system based on Cortex-A8 architecture and Linux Operation System. People could monitor various information in the remote client mode through it in different ways, like PC Qt server, pc browser and phone browser. Therefore, the system has convenient operation and large application range.The system is based on Cotex-A8 architecture and the Linux operating system. System can operate and control kinds of sensors through drive coding. Therefore, It could realize temperature, smog, personnel intrusion of the environment in real-time monitoring and get the video information of current environment. Users can observe video information currently through the client terminal by two ways, including monitoring through PC terminal and intelligent mobile phone terminal. When the smoke concentration of the environment is too high, or the temperature is too high, or there is personnel intrusion, the system will alarm by triggering the development board buzzer, user could view the current dangerous state.This paper realizes the choice and design of hardware and software of the multifunctional intelligent control terminal system. Paper briefly introduces the working principle and circuit diagram of various components. In terms of setting up the hardware environment, system realizes installing GNU ARM toolkits, building TFTP server and NFS server, writing u-boot, porting Linux kernel and making the root file system. Paper discusses drive and its programming method. System realizes the drive of various components by C language programming and miscdevice programming of character equipment. System uses Qt to realize the interface design and Qt server terminal and Qt client terminal. To realize the function of remote communication, system configures the IP address of development board, router, the client terminal and so on. Finally, paper tests each module, server terminal and client terminal, obtaining good results and realizing the basic expected functions of the system.The multifunctional intelligent control terminal system can be applied into many aspects, such as food or medicine storage control, indoor environment monitoring and supervision and so on. Therefore, it has good prospects of promotion.
