A wireless transmission technique for remote monitoring and recording system on power devices by GPRS network

A remote monitoring and recording system for power devices is developed in this paper. It aims at the application of the technology of wireless transmission and signal processing in the transmission of the signals of long-distance electric equipment to the central control station. The terminal visualizes its working states in pictorial system and saves all the historical data into general database for the purpose of future research and examination. Through this proposed system, only requires a GPRS matching acquisition system module which enables the long-distance control center to acquire any signals of the equipment, so that overall supervision is attained. Meanwhile, the task of wire setting on rough landform is avoided, and the time to overhaul can be saved. In addition, by examining the data record or analyzing them theoretically, we come to know the performance, life-span and operation efficiency of the equipment, so as to propose maintenance or replacement, thus the traditional periodical maintenance program is upgraded to a more efficient conditional based one. When anything abnormal happened to the equipment, the system can inform in advance the engineers concerned to repair it immediately or replace it, and reduces the occurrence of unexpected accidents.
