Intelligent household system can provide users with intelligent control plan, make the user's life more convenient and efficient, more can save unnecessary waste of resources in the family daily life, and provide reliable safety guarantee. Although the intelligent household system have certain of development, and corresponding product also begins to appear in the domestic market, but from the general development of intensity is temporarily behind the European and American countries. Began to study for the intelligent household system is very necessary.Embedded electronic products have mostly appeared in various fields of society, embedded technology has become one of the most popular study field. ARM become one of the most widely applied32-bit embedded processor with its characteristics of high performance, low power consumption, Linux operating system also with its powerful, free and rich of the development resources advantages dominated the embedded operating system. This design USES the ARM9(S3C2440+Linux) embedded system which widely used at domestic and overseas. This design equipped with a network of cameras, RFID reader, A variety of environment variables monitoring sensor.Realized monitoring image wireless transmission,environment variable real-time monitoring,rf entrance guard system.using Qt graphical interface to display the environment variable and rf card reading card information.The main job of this paper:Use Samsung S3C2440development board for embedded hardware platform which based on ARM9, given the overall scheme of this system and the overall framework. Established cross-compiling development environment, transplantation u-boot, embedded operating system and the file system, constructed a software development platform for the software design of this system. Choose the appropriate development hardware and sensor for the system, according to need to design and making circuit sensor node. Modify, design some hardware driver and compiled into the kernel. Introduce the method webcam realize image acquisition. Realizes rf card reading card and control of image for wireless transmission. Build the Qt graphical interface development platform, establish the project and design the application, realize the site signal display and sends out the corresponding equipment control signals.The experimental results show that this system can stable operation. Each sensor node normal work, rf reading card modules reading card and display user basic information stored on the radio frequency card in the right touch screen. Camera image acquisition success and can sent photos to the PC to be saved through wireless transmission module.This system realized the function of the reservation, to have the certain reference value. For later intelligent household system research and development and make further expand laid a foundation. |
