(4) when the optical cable is recovered, firstly, the communication optical cable terminal at the communication node A is wound on the auxiliary winding turntable, the optical cable to be recovered is fixed on the automatic optical cable buckle of the rotorcraft by the thread gluing on the auxiliary winding turntable, the rotorcraft is vertically lifted to a corresponding height according to the flight data recorded during laying operation, then a motor controller is informed by a wireless instruction to control the turntable driving motor to rotate reversely, the optical cable is wound on the main winding turntable, the take-up rotating speed of the turntable driving motor keeps synchronous with the flight speed of the rotorcraft, and after the rotorcraft automatically flies back to the communication node A, ground is put in with the optical cable terminal to the automatic unblock of optical cable, and manual fixes the optical cable terminal on main wire winding carousel, retrieves gyroplane receiver with the gyroplane in, closes main power switch, accomplishes the optical cable and retrieves work.
8. An optical cable automatic retracting method according to claim 7, characterized in that: in step (3) and step (4), the flying speed of gyroplane is controlled through rotor controller, and the tension sensor on the automatic buckle of optical cable detects the tension change in real time to adjust flying speed, and through wireless control and the rotational speed of fine setting carousel driving motor, thereby realize the quick matching of carousel driving motor rotational speed and gyroplane flying speed.
9. An optical cable automatic retracting method according to claim 7, characterized in that: in the step (3), the gyroplane pulls the optical cable to obliquely fly out of the recorded horizontal distance from the communication node A to the communication node B at an included angle of 45 degrees
And (4) doubling.
10. An optical cable automatic retracting method according to claim 7, characterized in that: in step (3), the battery power of the gyroplane is determined to meet the use requirement when the gyroplane is taken out, the battery power of the gyroplane is kept above 50%, the battery power is checked through the gyroplane controller, and in addition, data collected by the GPS sensor are transmitted to the gyroplane controller in a wireless transmission mode to be backed up.
