Abstract


With the development of economy and science and technology, people increasingly high demand for the quality of life, smart home technology came into being. The rapid development of information technology, the advent of the Internet age, provide a good environment for the smart home. Intelligent home using state-of-the-art computer technology, network communication technology and integrated wiring technology, the various subsystems related to home life together unified management, to make life more comfortable, safe and efficient, and has great prospects for development. Family intelligent system based on embedded system in the country has just started with the embedded technology is more widely used, the cost of gradually reducing the ultimate embedded smart home. This paper describes the RMON module in embedded systems. By understanding the implementation process of the video analysis algorithm, the computer intelligent video surveillance is an emerging field of computer vision applications direction and foreword topic of concern. As the TI's Davinci chip TMS320DM6446 processor hardware using C / S mode and B / S mode cross and the structure of the hybrid system, all software is divided into two parts: the embedded server part and the PC client part. The system in accordance with its specific function can be divided into three layers: the application layer, I / 0 processing layer, the signal processing layer. Application layer to achieve the framework of the entire embedded logic processing, network processing, storage management, alarm management, system interface functions; I / 0 processing layer to complete device driver; complete audio signal processing layer, video management, video analytics, alarm analysis, the OSD (on-screen character superimposed). Embedded software application layer subsystem Montavista Linux platform, embedded software signal processing layer subsystem using TI's DSP / BIOS platform. The entire software system using C / C language as a development language, will need a large number of program logic control and network control system is basically all packaging for the the ARM system program code, and then there will be a lot of calculation algorithm running on the DSP side, so as to achieve optimal configuration of the system. Finally, each module design, the initial realization of the need for a smart home remote monitoring. When a stranger into the home, the video monitor to the entire screen record, and alerts notify users.
