Home Real-Time Remote Monitoring System Based on Embedded Linux

Abstract Remote video monitoring is an important way of residential security. Due to some deficiencies of traditional home monitoring system such as high cost, large power consumption and difficult maintenance, this paper designs an economical and practical home real-time remote monitoring system. This system includes hardware design and software design. The hardware analyzes and compares the processor of different architectures to configure the model of microprocessors and the composition of peripheral circuits, and then identifies the S3C2440 chip as the system’s main controller. For the software part, this paper first studies the construction of embedded Linux system containing bootstrapper, kernel compile, files preparation system and transplantation; then it focuses on a detailed analysis of video capture module under Linux to present the main process of video capture under Linux when the USB camera is selected and design the video capture program based on the Video4Linux2 Linux programming interface; finally, it designs the B/S architecture-based video sending program for the video output module and achieves the real-time browse on a PC through a browser, thereby realizing the remote monitoring for residence. This system relies on the mature embedded technology and achieves the embedded Linux-based real-time remote monitoring system on the Mini2440 development board in accordance with the above design. Compared with the traditional monitoring system, this design has a lower cost and higher cost performance, so it is more practical for the home security.
