Video Data Transfer End System Based On GPRS

With the high-tech communication development, the long-range monitor system has been used widely in all areas, so people have higher demand for the media monitor system, and people are showing increasing interest in the development and design of a simple-operation, multifunctional, digital and good-price media monitor system.So developing one universal internet video equipment will have a very bright application future, if we base on that and consider different application requirements, we can make out all kinds of digital monitor systems. The system we have here is based on the wide application backgrounds and requirements nowadays, and use the new generation of EI technical idea to design and develop.This system uses video coding chip ZR36060 in hardware to code the digital video signal, use AT91 as control, NAND Flash as memory, GPRS module BENQ M23A as transmission equipment. In software, this system usesμC/OS-II as operation system to regulate tasks.This paper covers several parts to illustrate the system in detail. The first part includes the background, the significance of the study herein, the development of monitor system, along with the construct of this paper. The second part is to introduce the currently-adopted design scheme, to analyze the function and requirement for the system, address the overall frame design and provide a description of the initial design for the related software and hardware. The third part is to introduce the hardware based on AT91M40800 to deal with chips and its power supply module, CPU module, GSM module and video module. The forth part is to introduce the main module design of software, based on video number through NAND FLASH memory and introduce the memorizer design and come-truth process, in the meantime, it introduces the data transmission based on TCP/UDP. The fifth part is to introduce the set-up test flat roof and analyze the test result.
