7. An adaptive feeding method of the feeding apparatus according to claim 4 or 5, characterized by comprising:
the feed negotiator sends a negotiation instruction sent by the MOCA terminal equipment and received through the feed radio frequency interface to a feed router main chip;
the feed negotiator sends the received negotiation response instruction sent by the feed router main chip to a feed radio frequency interface appointed by the feed router main chip;
the feed negotiator sends negotiation content sent by the MOCA terminal equipment and received through the feed radio frequency interface to a feed router main chip;
the feed negotiator sends the received negotiation content response instruction sent by the feed router main chip to a feed radio frequency interface appointed by the feed router main chip;
the feed transmitter receives the power provided by the feed power supply according to the instruction sent by the feed router main chip and provides the power to a feed radio frequency interface appointed by the feed router main chip;
the feeding power converter converts the external power into power suitable for the electric element in the MOCA feeding equipment;
the feeding power supply converter provides power supply required by feeding to the feeding power supplier;
the feed negotiator periodically detects whether the feed radio frequency interface which is supplied with power receives a negotiation signal sent by MOCA terminal equipment or not according to an instruction of the main chip of the feed router;
and if the power feed negotiator does not detect the negotiation signal of the MOCA terminal equipment, cutting off the power supply from the power feed power supplier to the power feed radio frequency interface corresponding to the MOCA terminal equipment.
8. A wireless MOCA adaptive feed system, characterized in that the system comprises the wireless MOCA terminal device of any one of claims 1 to 3 and the wireless MOCA feed device of claim 4 or 5, the wireless MOCA terminal device and the wireless MOCA feed device are communicated through a coaxial cable, one end of the coaxial cable is communicated with a terminal radio frequency interface, and the other end of the coaxial cable is communicated with a feed radio frequency interface.
