New low-voltage power line network router system

The utility model discloses a novel low-voltage power line network router system. The system comprises a power line capable of bearing 220V/380V electric energy, coupling filters are arranged at the input end and the output end of the two ends of the power line respectively, a signal generator is arranged on the coupling filter located at the input end, and a signal receiver is arranged on the coupling filter located at the output end; wherein the coupling filter is composed of a high-pass filter of which the model is Butterworth; at the input end, the signal generator modulates signals to carrier frequency and sends the signals through the radio frequency line, the signals pass through the coupling filter and then enter the power line channel to be transmitted, and then at the output end,the signals on the power line pass through the coupling filter and are transmitted to the signal receiver through the radio frequency line. In the transmission process, the coupling filter is mainlyused for isolating alterna
