Abstract:
1. A powerline network system having data relay function, comprising: a plurality of power monitoring zones connected with a powerline network, and each having at least one power monitoring device; and at least one repeater, each connected with the power monitoring devices in two adjacent power monitoring zones through powerlines and having a first relay unit and a second relay unit; wherein the first relay unit is connected with the at least one power monitoring device in one of the two adjacent power monitoring zones to fetch data transmitted from the at least one power monitoring device to powerlines and output the data to the second relay unit, and receives and amplifies the data transmitted from the second relay unit and modulates the data with a first frequency band to transmits the data to powerlines; the second relay unit is connected with the first relay unit to transmit data thereto and receive data therefrom and is connected with the at least one power monitoring device in the other one of the two adjacent power monitoring zones through powerlines to fetch data transmitted from the at least one power monitoring device to powerlines, receives and amplifies the data transmitted from the first relay unit, and modulates the data with a second frequency band to transmit the data to powerlines, the first frequency band and the second frequency band are not the same.
