Implementation of Alternating Analog Input Board on ARM7

Abstract:

AC signal sampling technology is the basis of measure and control for electric power system and motor. A hardware synchronous AC signal sampling board is designed for an embedded SCADA system based on LPC2138 and ADS8365. The design principle and implementation methods of the hardware and software of the board are introduced in this paper. As parts of an eSCADA system, the modules have been brought into use at power plants and power control centers since 2012. The result of experiment and industry application shows that the sampling accuracy and real-time performance meet the requirements of relevant standards, and these boards work stably and reliably.
