Design Of ARM And Linux Based Substation Data Acquisition Terminal

With the progress of civilization and the improvement of social service awareness, improve power management level is increasing, places such as electricity substations and power plants collection methods can not meet the real-time requirements, and GPRS, PSTN and other means of communication have not diversification to meet the requirements of data transmission, DLT645、DLMS, such as meter statute restricts the development of meter reading.At present, the level of technology and communications has been fully able to meet the needs of remote meter reading. Before GPRS and PSTN, etc. due to the speed and stability of the electricity substation and other reasons have been making the acquisition system can not be deployed, but with the development of new technologies of communication is no longer constrained substation acquisition bottleneck. Using industrial-grade design collection terminal DF6205power substation collection terminal device, because of its powerful data processing capability is fully capable of handling large amounts of data Statute.Conform to the development needs of the grid, based on the third generation of ARM and Linux electricity substation collection terminals have been developed, which implements unified collection of electric energy to make electricity before the copy read complex work simple, manual operation becomes complicated The system automatically work. The third generation of energy acquisition using advanced ARM processor and Linux operating system to meet the needs of different manufacturers copied the statute read meter data. After years of testing and field validation, and ultimately achieve the automatic meter reading copy data automatically on to the main station and the background.
