Abstract
The invention relates to the technical field of power line carrier communication, in particular to a power-device remote monitoring system based on the power line carrier technology. The power-device remote monitoring system comprises a signal generator and a signal receiver. The signal generator is connected with one end of a power line through a signal modulation module, and the other end of the power line is connected with the signal receiver through a signal demodulation module. A plurality of communication safety detection modules are arranged on the power line at intervals, and the communication safety detection module is in wireless communication with the remote monitoring module. By means of the structure, attenuation of signals in power line carrier communication is detected through the communication safety monitoring modules arranged on the power line, then the detected data are transmitted to a remote monitoring module, and therefore whether the attenuation of the signals is normal or not is judged; in addition, whether power line carrier communication is normal or not is detected and judged through a power transducer.
