Abstract


Supervisory control and data acquisition (SCADA) system is a computer -based process control and scheduling automation systems This paper analyzes the problems of wireless data transmission technology , the domestic and international situation and development trend of the SCADA system , discussed in detail the GPRS technology and embedded RTLinux system characteristics . The SCADA system based on GPRS and RTLinux overall design philosophy , to achieve programs, as well as the overall structure of the system . The system mainly consists of monitoring center , remote the embedded monitoring terminals , data communication network is composed of three parts . Monitoring center and the remote embedded monitoring terminal linked through the Internet and the GPRS network for communication. The monitoring center uses B / S, C / S mixed on the Windows platform, the establishment of a monitoring program with a graphical interface , data and image monitoring function , and database management through the SQL language . FLASH ROM, SDRAM , and other peripheral chips and related hardware interfaces constitute a monitoring terminal through the 32-bit ARM microcontroller , embedded computer hardware platforms . Selection Embedded RTLinux operating system , composed of a common platform of embedded computer software to ensure the system 's real-time and facilitate the development and support network function . Monitoring terminal access to the mobile network , through the mobile gateway access to the Internet , to achieve data transmission via GPRS module . The solution has proved stable and reliable , real-time , transmission speed , and low cost advantages , to achieve a predetermined goal .
