A universal transparent transmission device for narrow-band power line communication relates to the technical field of data communication by using a low-voltage distribution network. It aims to solve the problem that the existing power carrier communication technology is still difficult to completely overcome the time-varying and frequency selectivity of power line channels. The data control bus end of the microprocessor circuit (1) is connected with the data control bus end of the power line modem module circuit (2), the two carrier signal output ends of the power line modem module circuit (2) are connected with the low-voltage distribution network through the strong and weak current isolation coupling circuit (4), and the carrier signal input end of the power line modem module circuit (2) is connected with the low-voltage distribution network through the receiving channel switch circuit (3), the strong and weak current isolation coupling circuit (4). The utility model can completely overcome the time-varying and frequency-selective problems of power line channels, and also has the advantages of strong adaptability to logical topology changes and long communication distance.
