As shown in fig. 1, 2 and 3, in the present invention, as positive terminals 1, 2, 3 and 4 of four power output terminals of a flight control machine-mounted communication device U are respectively connected with control power input terminals of four relays K1, K2, K3 and K4 through wires, normally open power output terminals of the four relays K1, K2, K3 and K4 are respectively connected with positive power input terminals of four lift motors M1, M2, M3 and M4 on an unmanned aerial vehicle itself through wires; therefore, only when one or more of the four relays K1, K2, K3 and K4 is/are powered to attract the control power supply input end and the normally open contact end of the relay to be closed, the positive electrodes 1, 2, 3 and 4 of the four-way power supply output end of the flight control airborne communication equipment U respectively enter the positive power supply input ends of the four lift motors M1, M2, M3 and M4 of the unmanned aerial vehicle, and further the four lift motors M1, M2, M3 and M4 can be powered to work respectively (in the invention, an operator can normally control the unmanned aerial vehicle to generate required flight actions after sending corresponding wireless control instructions through the voice instruction module U1 and the wireless signal remote control equipment U10. after receiving the instructions sent by the wireless signal remote control equipment U10, the four power supply output ends 1, 2, 3 and 4 of the unmanned aerial vehicle can respectively output or not output power according to different instruction signals, or power supplies with different voltages are respectively input into the positive power supply input ends of the four lift motors M1, M2, M3 and M4, and the four lift motors M1, M2, M3 and M4 are respectively or simultaneously powered on, so that the unmanned aerial vehicle can generate corresponding actions such as ascending, descending, advancing, retreating, steering and the like under the function of the unmanned aerial vehicle). Through the circuit action, because the instruction sent by the wireless signal remote control device U10 has the frequency hopping security function and also has the voice recognition control function (the voice recognition technology is a technology for controlling corresponding remote equipment by a voiceprint signal of a specific person through a network, the sound frequency of each person is different, therefore, the control technology based on the voice recognition has good security), when no corresponding voice instruction enters the singlechip module U8, relay K1, K2, K3, K4 can not be got electric actuation, then, the aircraft control machine carries the anodal 1 of communication equipment U four-way power output, 2, 3, the power of 4 foot outputs, just can not be controlled to get into four lift motor M1 respectively, M2, M3, the anodal power input of M4, that is to say, the instruction of disturbing the unmanned aerial vehicle flight will be invalid, the unmanned aerial vehicle can effectively receive legal user's control, better safe flight performance has.
As shown in fig. 1 and 2, the unmanned aerial vehicle has the function of keeping the flight control command secret by frequency hopping, and also has the function of keeping the flight control command secret by the voice command module, in application, the receiving end of the unmanned aerial vehicle correctly receives the frequency hopping flight control command at the same time, and after the correct voice command, the airborne communication equipment of the unmanned aerial vehicle controls the unmanned aerial vehicle to generate corresponding correct flight action, and any other interference command can not play a role in interfering the flight of the unmanned aerial vehicle, so that a double insurance effect is achieved, and better flight control communication secrecy performance can be obtained.
