The Embedded Monitoring System Based On ARM

With the development of electronic information technology, the application of embedded system is widely used in every industry, such as Consumer electronics, Hand-held devices, firewall, Industrial control and so on. Among them, Video monitoring system is an important aspects of embedded system, and it appears more and more important in traffic,safety and daily life.This thesis is derived from actual project development based on constructing embedded software development, detailedly does research on the application of embedded system in monitoring system, does certain research on the transmission part of image, does deep research on how to transmit data and how to store data, and gives detailed solutions.And at the same time does some research on the serial driver,realizes the serial driver program of this project.The main contents is divided into three parts:Part 1 is the design of the embedded monitoring system.From the introduction the hardware platform of embedded system to the selection of processor and the acquisition module. and the image transmission module in the end. Part 2 is the set up of platform.This thesis is based on the hardware platform of the MINI2440 Development Board, make Cross-compiler environment that can compile Soft-float, transplants BootLoader, customizes linux shell, makes Yaffs root file system to constructs perfect embedded platform.1. Part 3 is the image acquisition module and image transmission module, drives serial device that is used to enable the application program to operate the hardware.This thesis adopts the GPRS communication module of Siemens MC55.This module is with the function of transmission ability, data reception ability and the serial camera of Star Electronics to constructs the control part of embedded system.On the basis of introducing the construction of embedded platform in detail, this thesis made some research on serial driver, and explored the collection, storage and transfer of images and so on. And then, this thesis introduced the key steps and technology used, the solution to the problems appeared during the process of image transferring, presented the construction method for embedded Linux in monitoring system.
