The Application of GSM and GPRS Technology in Monitoring System for HVDC System Earth Pole

摘要

The paper presented application and realization of GSM and GPRS network in on-line monitoring system of earth pole system. In its on-site unit, which is solar energy technology, the value of the current, temperature and depth of water variables are obtained from different sensors. These data are preprocessed in a DSP chip and then transmitted GSM and GPRS wireless communication networks. Based on software of system management, the operating condition of HVDC system earth pole can be diagnosed. The monitoring system raise the fault alarm for based on SM.
