Powerline network system having data relay function
First Claim
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;
whereinthe 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.

Abstract
A powerline network system having data relay function includes a plurality of power monitoring zones mutually connected with a powerline network and at least one repeater. Each of the power monitoring zones has at least one power monitoring device. The repeater is connected with each power monitoring device in two adjacent power monitoring zones through powerlines and has a first and a second relay units. The first and second relay units employ two different sets of transmitting and receiving bands to fetch data contained in powerline signals transmitted by each power monitor in adjacent power monitoring zones. The data are received by a relay unit are modulated with different transmitting band and then transmitted to powerlines of another power monitoring zone. The repeaters are not required to be serially connected to the powerlines, and incorrect data read can be also eliminated.
