The design of electric power parameters measuring system based on wireless

摘要

The electric power parameters remote measuring system based on wireless is designed. The measuring data is transmitted to monitor center by GPRS network, analyzed and processed. Then the electric power parameters are recorded and displayed, which presents the real time measuring to electric power parameters. The Local detection unit is designed, which can implement continuum automatism multi-points measuring. A dedicated energy measurement chip is used to collect voltage, current, power, which access to mobile network by SIM card. The most of the data processing work is done by a dedicated IC, reducing the burden on the microcontroller, simplifying the circuit design to improve the system stability and accuracy. Field test, indicating that the effectiveness of the design.
