The utility model discloses a far-end signal forwarding device of a power line network. The system comprises near-end equipment and far-end equipment, the near-end equipment is in communication connection with the concentrator; the near-end equipment is also connected with the special transformer acquisition terminal; the far-end device and the near-end device are in communication connection through a power signal line. The far-end device is connected with the main station through the GPRS bidirectional communication module. The GPRS bidirectional communication module comprises a first GPRS module, a second GPRS module and a protective shell assembly. The first GPRS module and the second GPRS module are installed at the top end of the protective shell assembly through the turnover assembly. A solar storage battery assembly is further installed at the top end of the protective shell assembly. the communication of the double GPRS modules improves the signal transmission and feedback efficiency; the solar storage battery assembly serves as a standby power supply of the GPRS module when a main power supply of the GPRS module is powered off, energy conservation and environmental protection are achieved, stability and continuity of signal transmission of the GPRS module are guaranteed, and the GPRS module is easy to overhaul and maintain.
