Abstract


Designed to meet the need for condition monitoring gapless zinc oxide arrester (MOA) , MOA leakage current data acquisition and transmission system . The proposed new method of a communication chip nRF905 RF - based short-range wireless data transmission technology , GPRS remote data transmission technology and the internet Internet data transmission technology . The monitoring system includes front-end data acquisition unit , nRF905 wireless data transmission unit , GPRS remote data transmission unit , the application of the ADSL Internet data transmission part and the remote monitoring center . The monitoring system set signal acquisition , communication , analysis , calculation and storage in one , with real-time monitoring , waveform display , historical data query functions . Modular design for easy expansion of access of other electrical equipment monitoring system to improve the level of application of the existing online monitoring technology has played a good role in promoting .
