An on-line monitoring system for MOA based on DSP and GPRS

Aiming at the existing problems in the traditional on-line monitoring system for MOA such as low measurement precision, poor stability and wire transmission type to be used and so on, a novel design scheme for MOA on-line monitoring system is designed based on DSP and GPRS. Lower computer of the system takes DSP as core, which achieves real-time detection of resistive current of MOA through on-spot collection signals and FFT algorithms, and transfers data to upper computer through GPRS transmission module to be processed. Upper computer management system can monitor real-time state of MOA and query historical data to be analyzed, electric power system can run in the reliable state. The whole Monitoring system has good anti-jamming performance and high measurement precision, and test results meet the design requirements.
