The Wireless Image Surveillance System Based On GPRS

With the development of information technology and the popularization of digital product, the embedded devices are broadly used in the field of industry agriculture and commerce etc. The surveillance systems based on embedded system are progressing with the tendency of digital and network application which is including from analog signals to digital signals and from cable transfer to wireless transfer. At the same time, the trends of being more pocket and intelligent are also the direction of the development of surveillance system.This project is the application of the embedded system and the wireless network in the filed of surveillance system. The hardware system is based on the ARM microprocessor platform and the software system is based on the embedded Linux system. Firstly, we researched the design and transplant of embedded Linux system with GUI (Graphical User Interface). We developed some applications with the function of snapping, showing and transmitting photos. All the operations can be finished on the embedded terminal and you can even chat with long-distance server.Then, we designed an intelligent surveillance system which can realize the function of surveillance without supervisor. This surveillance system can automatically notice consumers by SMS and transmit the photoes to the server when there are abnormal accidents happening.The dissertation introduces the development and research status of the surveillance systems, and then introduces the hardware and software of the experimental development platform. On these fundaments, the dissertation describes the research of the embedded system with GUI and the config of the wireless network with emphasis. Also, we designed an experimental terminal including the design of the hardware (PCB) and software (Operating System and applications). Finally, a method of Digital Image Processing with high efficiency based on embedded Linux is indicated.
