Abstract: A remote monitoring management system of electric power device includes a radio acquisition device and a data converter. The radio acquisition device consists of a current transformer, a wide current constant-voltage converting circuit, a current sampling circuit, an AC A/D acquisition unit, an AVR main control unit, a temperature sensor, a temperature measuring circuit and a radio transmitting and receiving circuit. The data converter consists of a radio transmitting and receiving circuit, a hardware clock circuit, an AVR main control unit, a RS485 data communication interface and a voltage regulation power supply. The radio transmitting and receiving circuit includes a radio receiving circuit and a radio transmitting circuit, and adopts GFSK modulation, and has the transmitting and receiving frequency of 433MHz, or 868MHz, or 915MHz. The system implements monitor of the high-voltage device locally, in time and quantificationally, and can be easily applied to the remote control system.
