GPRS-based embedded remote power management system

This paper implements a GPRS-based embedded system for load management system in real time remote operation to power equipments in general applications. The proposed system is designed using a 32-bit ARM-7 embedded microprocessor system to carry on power data processing and relay control through GPRS mobile communication. In order to provide a cost-effective, wireless, always-connected, two-way data link function capability, the proposed system establishes a remoter monitor and control center to manage power equipment operation data, power parameters and outage signals. To activate the data flow, GPRS is used to handle real time message in two ways, from equipments to the control server, and from operator to the equipments. In this paper, the proposed system is successfully built tip, and a full function of real time remote operation is tested with data collection, especially at a system outage. This paper verifies the proposed system is useful and effective to power equipment monitor and control in a real time and mobile condition.
