The Embedded Wireless Remote Video Monitor System Based On ARM

Viewable real-time monitoring is an important application of remote measurement and control technology, which can be used in many fields, such as traffic control, public security, national defense and so on. It acts a more and more important role in our daily life.This paper introduces the investigation of the embedded system which is based on ARM. The system can be wireless monitored by video from far away. It uses the USB web-camera with the chip of ZC301, which is low in price and high in quality. Through the module of GPRS, pictures will be sent back to the control center in the distance.At first, some kinds of embedded operation systems and the situations of ARM processor are introduced. Secondly, the paper analyzes the kernel of embedded Linux, and introduces the Bootloader. Then it researches the driver of USB device and the transplantation of embedded Linux on the ARM platform. Finally the realization of video signal capture under embedded Linux is discussed in detail.With regards to the hardware design, the embedded video capture system is consist of USB camera and S3C2410 as its CPU, and as it connects to PC through Ethernet, the system of video inspecting can work well.As far as the software design, the system software and the internet applications must be designed. First we must put the Bootloader and embedded Linux kernel to the target of ARM platform. Then a system of video capturing and a GPRS module need to be designed to run on the platform of ARM. In the end we should design a control client module.
