The transmitting end device 102 includes a power supply 104, an inverter 105, a first resonant circuit 106 and a transmitting coil 107. The receiving end device 103 includes a receiving coil 108, a second resonant circuit 109 and a rectifier 110.

[0037] In this embodiment, the present invention generates strong electricity through the sending end device 102, and then the strong electricity generates a magnetic field or an electric field, and the magnetic field or the electric field is received by the receiving end device 103 and converted into electricity to provide power for the UAV body 101, thereby realizing wireless transmission of electricity, thereby increasing the range of the UAV, extending the continuous operation time of the UAV in the air, enabling the UAV to fly farther, expand the flight radius or the scope of performing tasks, and at the same time, can enhance the flight capability and maneuverability of the aircraft, reduce dependence on ground bases, thereby reducing the logistics support work of the ground base, and solve the existing power transmission method that mostly relies on wired connections. This method not only limits the mobility and flexibility of the equipment, but also may cause energy loss and safety hazards due to problems such as line aging and poor contact.

[0038] Among them, the sending end device 102, the receiving end device 103 and the drone body 101 are connected in sequence, and the receiving end device 103 is arranged in the drone body 101; the sending end device 102 is used to generate direct current, and then convert and modulate the direct current, and finally convert it into a magnetic field or an electric field; the receiving end device 103 is used to receive the magnetic field or electric field generated by the sending end device 102, and then convert and transform the magnetic field or the electric field, and finally obtain direct current to provide power for the drone body 101.

[0039] Secondly, the power supply 104, the inverter 105, the resonant circuit and the transmitting coil 107 are connected in sequence; the power supply 104 is used to generate direct current and transmit the generated direct current to the inverter 105; the inverter 105 is used to convert direct current into high-frequency alternating current and transmit the high-frequency alternating current to the resonant circuit; the first resonant circuit 106 is used to adjust the frequency of the high-frequency alternating current to the resonant frequency and transmit the resonant frequency to the transmitting coil 107; the transmitting coil 107 is used to convert the high-frequency alternating current in the first resonant circuit 106 into a magnetic field or an electric field.

[0040] Again, the receiving coil 108, the second resonant circuit 109 and the rectifier 110 are connected in sequence; the receiving coil 108 is used to receive the magnetic field or electric field generated by the transmitting device 102, and transmit the magnetic field or the electric field to the second resonant circuit 109; the second resonant circuit 109 is used to convert the received magnetic field or the electric field into high-frequency alternating current, and transmit the high-frequency alternating current to the rectifier 110; the rectifier 110 is used to convert the high-frequency alternating current into direct current to provide power for the drone body 101.

[0041] Finally, between the transmitting device 102 and the receiving device 103, by adjusting the parameters of the first resonant circuit 106 and the second resonant circuit 109, the resonant frequencies of the transmitting device 102 and the receiving device 103 are made the same, thereby achieving magnetic coupling resonance or electric field coupling, and further achieving wireless transmission of power.

This method not only limits the mobility and flexibility of the equipment, but also may cause energy loss and safety hazards due to problems such as line aging and poor contact.

[0045] Second embodiment:

[0046] Based on the first embodiment, please refer to Figure 2 and Figure 3 , Figure 2 is a schematic diagram of the overall structure of the UAV long-distance power transmission system according to the second embodiment of the present invention, Figure 3It is a control principle diagram of the long-distance power transmission system for an unmanned aerial vehicle of the second embodiment of the present invention. The present invention provides a long-distance power transmission system for an unmanned aerial vehicle, which also includes an energy storage device 201 and an intelligent control device 202. The energy storage device 201 includes an energy storage device 203 and a power controller 204. The intelligent control device 202 includes a command input module 205, a control module 206 and a display module 207.

[0047] In this embodiment, the energy storage device 201 can store excess electrical energy in the energy storage device 201 and provide power to the drone body 101 when needed. The intelligent control device 202 can remotely control the start and stop of the sending end device 102.

[0048] Among them, the receiving end device 103, the energy storage device 201 and the drone body 101 are connected in sequence, and the energy storage device 201 is arranged in the drone body 101, and is used to store excess electrical energy in the energy storage device 201, and provide power to the drone body 101 when needed.

[0049] Secondly, the energy storage device 203 is connected to the power controller 204; the energy storage device 203 is used to store excess electrical energy; the power controller 204 is used to transmit the electrical energy in the energy storage device 203 to the drone body 101 to provide power for the drone body 101.

[0050] Meanwhile, the energy storage device 203 is a battery that can be charged or discharged.

[0051] In addition, the intelligent control device 202 is connected to the sending end device 102 and is used to control the start and stop of the sending end device 102.

[0052] Finally, the instruction input module 205, the control module 206 and the display module 207 are connected in sequence, and the control module 206 and the display module 207 are both connected to the power supply 104; the instruction input module 205 is used to input operation instructions and transmit the input operation instructions to the control module 206; the control module 206 is used to analyze and process the received operation instructions, and generate corresponding operation instructions to control the start and stop of the power supply 104; the display module 207 is used to receive the power generated by the power supply 104 and display the power.

[0053] When using a long-distance power transmission system for an unmanned aerial vehicle of the present embodiment, when it is necessary to control the navigation of the unmanned aerial vehicle, an operation instruction is input into the instruction input module 205, so that the instruction input module 205 can transmit the input operation instruction to the control module 206, so that the control module 206 can analyze and process the received operation instruction, and generate corresponding operation instructions, thereby realizing remote control of the start and stop of the power supply 104. When the power supply 104 is started, the power supply 104 will generate direct current and transmit the generated direct current to the inverter 105. At the same time, the power supply 104 will transmit the power status generated by itself to the display module 207, so that the display module 207 can display the power status generated by the power supply 104, so that the user can view the power status generated by the power supply 104 in real time.

[0054] When the power supply 104 transmits the generated direct current to the inverter 105, the inverter 105 can convert the direct current into high-frequency alternating current, and transmit the high-frequency alternating current to the resonant circuit. Afterwards, the first resonant circuit 106 can adjust the frequency of the high-frequency alternating current to the resonant frequency, and transmit the resonant frequency to the transmitting coil 107, so that the transmitting coil 107 can convert the high-frequency alternating current in the first resonant circuit 106 into a magnetic field or an electric field, and transmit it out.

[0055] The magnetic field or electric field generated by the transmitting coil 107 is received by the receiving coil 108, and the magnetic field or the electric field is transmitted to the second resonant circuit 109, so that the second resonant circuit can convert the received magnetic field or the electric field into high-frequency alternating current, and transmit the high-frequency alternating current to the rectifier 110. After that, the rectifier 110 can convert the high-frequency alternating current into direct current, so as to provide power support for the navigation of the drone body 101. Between the transmitting device 102 and the receiving device 103, by adjusting the parameters of the first resonant circuit 106 and the second resonant circuit 109, the resonant frequencies of the transmitting device 102 and the receiving device 103 are made the same, thereby realizing magnetic coupling resonance or electric field coupling, and further realizing wireless transmission of power.

[0056] When the rectifier 110 has excess electric energy while providing power support for the navigation of the drone body 101, the excess electric energy can be transmitted to the energy storage device 203 and stored in the energy storage device 203, so that when there is no power transmission in the future, the electric energy in the energy storage device 203 can be transmitted to the drone body 101 through the power controller 204 to provide power for the drone body 101.
