Take-off and landing sliding distance measurement device for unmanned plane, and unmanned plane therewith

The invention discloses a take-off and landing sliding distance measurement device for an unmanned plane, and the unmanned plane therewith. The device comprises a connecting frame, a storage wheel, a rocking arm, a distance measurement sensor, and a wheel-mounted switch. The wheel-mounted switch is connected with a flight control system of the unmanned plane, and is disposed on the connecting frame. The wheel-mounted switch has two states: a first state and a second state. One end of the connecting frame is connected with the main body of the unmanned plane, and the other end of the connecting frame is hinged to the storage wheel through the rocking arm. The rocking arm can rotate relative to the connecting frame, thereby enabling the rocking arm to have a disconnection position and a connection position. The storage wheel is hollow, and can rotate relative to the rocking arm. The distance measurement sensor is connected with the flight control system. The distance measurement sensor is disposed in the storag
