<p>Device for the bidirectional transmission of data between an energetically autonomous mobile and a control and command station, knowing that said bidirectional transmission of data is performed by virtue of an optical fibre (FO) linking said control and command station to said energetically autonomous mobile, and being wound in adjoining spirals around a fixed drum (T) centred around an axis (?), carried aboard said energetically autonomous mobile; said fixed drum (T) comprises: - an optical/electrical bidirectional conversion circuit (CC2) associated with the free end of said optical fibre (FO), and - a rotating payout mechanism (DEV2), mounted coaxial with the axis (?) of said drum (T), the speed of rotation of which is dependent on the speed of displacement of said energetically autonomous mobile.</p> |
