Detailed description of the invention

The invention will be further described with embodiment below in conjunction with the accompanying drawings.

As it is shown in figure 1, give the structural representation of a kind of unmanned plane, it is 18 rotation unmanned planes, manipulates nothing for new hand During man-machine or unmanned plane flies under dim dark state, operator are difficult to identify the current flight side of unmanned plane To, it is unfavorable for that unmanned plane flies according to set path.

As in figure 2 it is shown, give navigation lights distribution schematic diagram in frame, the quantity of shown navigation lights 2 is 8, point Be not 2 red lights, 2 blue lamps, 2 green lights, 2 amber lights, its be respectively arranged at the left side below frame 1, left front, front, right before, Behind right, the right side, left rear, rear, in order to during unmanned plane during flying, whether manipulation personnel it can be seen that the lighting of navigation lights.

As it is shown on figure 3, give the circuit diagram of the UAV Intelligent caution system of the present invention, it is by microcontroller 3, control Circuit 4, keyset 5, flight controller 6, receiver of remote-control sytem 7, remote controller 8, power circuit 9, clock circuit 10, USB interface electricity Road 11, debugging circuit 12, warning circuit 13, microcontroller 3 has collection, computing and control action, microcontroller 3 and flight control Device 6 processed is connected through order wire.Flight controller 6 is connected with receiver of remote-control sytem 7, and flight controller 6 is responsible for controlling unmanned plane Flight, flight controller 6 obtains, by receiver of remote-control sytem 7, the heading signal that remote controller 8 sends, and according to heading Signal controls the flight of unmanned plane.
