The Study Of SCADA System Base On GPRS

Along with the development of the mobile communication technology and market, the mobile data communication has become the new developing orientation of the data communication. GPRS is one of the realizations based on GSM Phase 2.1, and it supports the protocol of IP and X.25 so that it can afford a self-contained communication project based on the TCP/IP protocol.The Supervisory Control And Data Acquisition system(SCADA) is a production course control and attemperment automatization system based on computer. It can supervise and control the operating facilities on the spot.The maturity and the broad applications of GPRS technology provide a new communication mode for SCADA system.The text mainly introduces the GPRS terminal design , the interface with user equipment, the disposal of the TCP/IP protocol, the mutual connection between the GPRS terminal and the data center , network access and software design of data center and so on. The text especially discusses the design of GPRS data transition terminal, and resolves the matter of the data and commands of TCP/IP protocol packed or unpacked and the problem of GPRS terminal clinging to network automatically, and moreover, presents the program design of data center.The SCADA system based on GPRS has a even more broader application scope that is applicable to almost all sorts of data transition operations with middle or low rate in any environment, such as INTERNET access, personal information, finance, traffic and so on.
