Abstract
The power line carrier system provides with a filter in a power branch apparatus removable from an external power line. The filter passes a power line carrier signal in a signal mode for the external power line, and interrupts another power line carrier signal which is in a signal mode different from the mode for the external power line.
Claims19
A power line carrier system for performing a power line communication over power lines, said system comprising:
- an electric device possible to perform the power line communication at least in a signal mode for an in-house external power line;
- and
- an apparatus which is removable from the external power line and provided with a signal selector between a side of receiving power from the external power line and a side of supplying the power, said signal selector passing a power line carrier signal in the mode, and interrupting another power line carrier signal which is in a signal mode different from the mode for the external power line.
An electric device possible to perform a power line communication in a signal mode for an in-house external power line, wherein a signal is converted from in the mode to in another signal mode according to an electric device of destination of the signal.
A power branch apparatus for branching power supplied from an in-house external power line, and supplying the power to a connected electric device, which comprises
- a signal selector between a side of the external power line and a side of the electric device, said signal selector passing a power line carrier signal in a signal mode for the external power line, and interrupting another power line carrier signal which is in a signal mode different from the mode for external power line.
A method for performing a power line communication between electric devices connected to a power line over the power line, said method comprising the steps of:
- deciding to adopt either one of a signal mode for an in-house external power line and a different mode from the mode according to an electric device of destination;
- and
- performing power line communication with the electric device in the decided mode.
