Research Of Remote Data Communication System Based On GPRS Technology

With the development of the communication technology, the wireless network is applied in the data transmission of the industry more and more. At present, the way of wired communication to transmit data has been mostly used in the field of industry, though very economical and practical, wired data transmission has limited its application prospects to a large extent. In order to make the remote transmission more flexible and convenient, in this paper, GPRS technology has been selected to transmit the remote data. There has the advantage of wide coverage, always online characteristics on GPRS technology, which can also been widely used in electronic control, railway, petroleum,etc. This shows the trend in the field of industrial control and remote monitoring.In this Paper, the remote data communication system based on GPRS composed of the data center and the transmission terminal, which are connected through the Internet and GPRS network. Taking the client/server model and the connection serve as a whole is to carry out network transmission. The data center can be a computer with the function of network, and the transmission terminal is an embedded system that consisted of S3C44B0X processor and other interfaces. And it can be connected to the Internet through a GPRS modem.Through compared the present ways of the wireless data transmission, GPRS has been choosen as to transmit the remote data. Firstly, explaining the GPRS in detail, including its system frame and its network feature. Then, designing the data communication system, mainly analyzing the form-net project and the communication scheme of the system,and the function of the constitution, besides, analyzing the system's security . Adopting the μC/OS- Ⅱ as the software development platform and the S3C44B0X processor and other interfaces to constitute the DTU terminal,which realized the data transparence transmission.MFC's...
