Method, device and system for scanning equipment in electrically adjustable antenna interface

The invention discloses a method for scanning equipment in an electrically adjustable antenna interface, which comprises that: a central control unit broadcasts an equipment scanning request message to each far-end control unit controlled by the central control unit, and receives an equipment scanning response message sent by a far-end control unit in a no-address state; and the central control unit allocates an address for the far-end control unit sending the equipment scanning response message. The invention also discloses a device and a system for scanning equipment in the electrically adjustable antenna interface. By adopting the scheme, the far-end control unit does not need performing unique identification code matching operation so as to shorten the time for scanning the far-end control unit by the central control unit.
