The Research Of Wireless Image Transmission System Based On GPRS

With the gradual improvement of living standards, people's safety in an increasingly high demand. Human vision is the most important sensory organ, the facial features of people rely on the information obtained from the outside world 80 percent of the total, the image information is the objective world by the major source of access to information, on many occasions, especially for some of the scattered, and no one Duty of the scene, people always want to be in need of real-time image information, which requires timely data collection, in order to understand the scene, according to the situation and send control commands. Wireless image transmission system is in this context of the application.In this paper, a design based on GPRS (General Packet Radio Service) network of wireless image transmission system. The system consists of image acquisition, image storage and GPRS module consists of three parts, the three control centres on achieving common units designated to understand the real-time information and police intelligence handling capabilities. Since this system is in low cost, reliability and other advantages of data, can be widely applied to live and work in the fields.Paper focuses on the image acquisition, image storage and image sent the principle and work process. Hardware, the C8051F015 MCU on the basis of memory chips by increasing HM62256, in the hardware store on the system to meet the demand, with embedded TCP / IP protocol stack to achieve the SIM300C image of the wireless transmitter and thus the present system The principle of the structure and composition. C51 use software programming language, allowing the system to achieve the image data collection, storage and wireless transmitter.The system made full use of existing GPRS network and improve data transfer rate and increase the data throughput and reduced operating costs, achieved the expected goals, better able to meet the needs of users.
