[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] Combination Figure 1 The multi-functional unmanned aerial vehicle (UAV) device proposed in this embodiment of the invention is specifically as follows: The laser energy transmission and communication module 4 is used to provide optical energy and transmit and receive optical signals from the spool fiber 301. 3. The spool contains optical fiber 301 and connects the UAV 1 and the laser energy transmission and communication module 4. The unmanned aerial vehicle 1 is used to establish communication with the second bidirectional optical module 402 of the laser energy transmission communication module 4 through the wire spool optical fiber 301 in the wire spool 3, to forward the optical signal of the second bidirectional optical module 402 to become a communication relay station, to send the optical signal of itself to the outside world through the internal first bidirectional optical module 103 and the capture, tracking and alignment module 2, to receive the optical energy from the energy transmission laser 403 of the laser energy transmission communication module 4 to charge itself, to forward the external laser energy to act as a laser weapon or to charge the friendly unit, to receive energy to charge itself through the capture, tracking and alignment module 2, to collect information through the sensing module 102, to transmit the information to the main control circuit board 101 for processing, to convert the optical signal through the first bidirectional optical module 103, and to emit the optical signal through the space communication link or the optical fiber communication link. The unmanned aerial vehicle 1 is connected with the laser energy transmission communication module 4 through the wire spool optical fiber 301 in the wire spool 3, wherein the wire spool 3 contains a mechanical mechanism for cutting off the wire spool optical fiber 301 under certain conditions, at which time the energy supply of the unmanned aerial vehicle 1 is mainly borne by the energy storage battery 111, and the external optical energy can be received by the capture, tracking and alignment module 2 to supplement.

[0022] Specifically, the dashed line in the attached Figure 1 represents electrical connection, and the solid line represents optical fiber connection. Each bidirectional optical module supports receiving and transmitting optical signals, and transmits and receives optical signals of different wavelengths, and contains an optical filter for separating the two wavelengths. For example, the first bidirectional optical module 103 transmits optical signals of wavelength λ1 to the second bidirectional optical module 402, and can also receive optical signals of wavelength λ2 from the second bidirectional optical module 402, while the second bidirectional optical module 402 transmits optical signals of wavelength λ2 to the first bidirectional optical module 103, and can also receive optical signals of wavelength λ1 from the first bidirectional optical module 103. Both bidirectional optical modules contain an optical filter for separating optical signals of different wavelengths in two directions. However, λ1 and λ2 can also be the same, at which time a circulator is needed to separate the optical signals in two directions, but the cost of using a circulator is higher, and the advantage is that the wavelength resource can be saved.

[0023] In the preferred embodiment of the present application, the external laser energy transmission system comprises a second wavelength division multiplexer 401, a second bidirectional optical module 402 and an energy transmission laser 403, The first optical signal generated by the second bidirectional optical module 402 and the second optical signal generated by the energy transmission laser 403 are combined into the optical signal through the second wavelength division multiplexer 401, and the optical signal is transmitted to the unmanned aerial vehicle 1 through the wire spool optical fiber 301; The second bidirectional optical module 402 and the energy transmission laser 403 are connected with P1 and P2 of the second wavelength division multiplexer 401 respectively, and the COM end of the second wavelength division multiplexer 401 is connected with the unmanned aerial vehicle 1 through the wire spool optical fiber 301.

[0024] In the preferred embodiment of the present application, the unmanned aerial vehicle 1 further comprises a third optical switch 106 and a first optical switch 104, and the multifunctional unmanned aerial vehicle device is specifically used for: The communication system of the unmanned aerial vehicle 1 is constructed based on the switch states of the third optical switch 106 and the first optical switch 104, and the communication system comprises an optical fiber communication system, a space communication link or a space communication forwarding link; When the third optical switch 106 is in the non-setting state, the P1 end and the P3 end, and the P2 end and the P4 end of the third optical switch 106 are connected; when the third optical switch 106 is in the setting state, the P1 end and the P4 end, and the P2 end and the P3 end of the third optical switch 106 are connected.

[0025] In the preferred embodiment of the present application, the unmanned aerial vehicle 1 further comprises a first bidirectional optical module 103 and a capture, tracking and alignment module 2, and the multifunctional unmanned aerial vehicle device is specifically used for: When the third optical switch 106 is in the non-setting state, the optical signal of the second bidirectional optical module 402 enters the first bidirectional optical module 103 through the P1 end and the P3 end of the third optical switch 106, so as to construct the optical fiber communication system of the unmanned aerial vehicle 1 and an external laser energy transmission system; When the third optical switch 106 is in the setting state and the P2 end of the first optical switch 104 is connected with the COM end, the signal of the first bidirectional optical module 103 is transmitted to the P2 end-COM end of the first optical switch 104-P1 end-COM end of the third wavelength division multiplexer 108-capture, tracking and alignment module 2 through the P3 end-P2 end of the third optical switch 106, so as to form the space communication link between the first bidirectional optical module 103 and the capture, tracking and alignment module 2; When the third optical switch 106 is in the setting state and the P1 end of the first optical switch 104 is connected with the COM end, the communication optical signal from the second bidirectional optical module 402 is transmitted to the P1 end-COM end of the first optical switch 104-P1 end-COM end of the third wavelength division multiplexer 108-capture, tracking and alignment module 2 through the P1 end-P4 end of the third optical switch 106, so as to form the space communication forwarding link between the laser energy transmission communication module 4 and the capture, tracking and alignment module 2; The first bidirectional optical module 103 is connected with the P3 end of the third optical switch 106, the P4 end of the third optical switch 106 is connected with the P1 end of the first optical switch 104, the P1 end of the third optical switch 106 is connected with the P1 end of the first wavelength division multiplexer 107, the P2 end of the third optical switch 106 is connected with the P2 end of the first optical switch 104, the COM end of the first optical switch 104 is connected with the P1 end of the third wavelength division multiplexer 108, and the COM end of the third wavelength division multiplexer 108 is connected with the capturing, tracking and aligning module 2.

[0026] In the embodiment, the light from the bidirectional optical module and the energy transmission laser 403 outside the unmanned aerial vehicle 1 is combined by the second wavelength division multiplexer 401, transmitted through the long spool optical fiber 301, and reaches the unmanned aerial vehicle 1, wherein preferably, the spool optical fiber 301 uses a conventional communication optical fiber, and the energy transmission laser 403 selects a wavelength in a low-loss window of the communication optical fiber, so that the cost of the spool 3 can be reduced, and the energy loss in the energy transmission process can be reduced.

[0027] In the embodiment, the spool 3 internally contains a long optical fiber, and the optical fiber of the spool 3 is continuously thrown out during the flight of the unmanned aerial vehicle 1. The energy transmission laser 403 located outside the unmanned aerial vehicle 1 is connected with the optical fiber of the spool 3. The optical fiber functions to transmit laser energy. The spool 3 contains a mechanical mechanism, which can cut off the spool optical fiber 301 when necessary, so as to further improve the combat radius. At this time, the energy supply of the unmanned aerial vehicle 1 is mainly borne by the energy storage battery 111, and the external optical energy received by the capturing, tracking and aligning module 2 can be used for supplement.

[0028] In the embodiment, the internal energy path and the communication path of the unmanned aerial vehicle 1 are separated by the first wavelength division multiplexer 107. When the light from the second bidirectional optical module 402 is separated by the first wavelength division multiplexer 107, it enters the P1 end of the third optical switch 106. In the unset state of the third optical switch 106, the light of P1 is guided to P3, and the light of P3 enters the first bidirectional optical module 103 inside the unmanned aerial vehicle 1, so as to build the optical fiber communication system between the unmanned aerial vehicle 1 and the outside. Similarly, since the third optical switch 106 is bidirectional, the light emitted by the first bidirectional optical module 103 can also be transmitted to the second bidirectional optical module 402 and received thereby.

[0029] In the embodiment, in the set state of the third optical switch 106, its P3-P2 and P4-P1 are simultaneously connected, and there are the following two cases: (a) When the first optical switch 104 (P2→COM), the first bidirectional optical module 103 is connected with the capturing, tracking and aligning module 2, and a space communication link of the unmanned aerial vehicle is built.

[0030] (b) When the first optical switch 104 (P1→COM), the second external bidirectional optical module 402 is connected with the capture, tracking, and alignment module 2, and a space communication relay link of the UAV is constructed.

[0031] Specifically, the third optical switch 106 can be implemented by a 2X2T mechanical optical switch.

[0032] In the preferred embodiment of the present application, the UAV 1 further comprises a second optical switch 105, which is specifically used for: receiving the energy optical signal and constructing a weapon system of the UAV 1, relaying laser energy, or charging the UAV 1 itself based on the port connection state of the second optical switch 105.

[0033] In the present embodiment, the energy path light is separated by the first wavelength division multiplexer 107 and enters the second optical switch 105. When energy needs to be relayed or used as a weapon, the second optical switch 105 (COM→P1) passes through the circulator 109 (P1→P2) and the third wavelength division multiplexer 108 (P2→COM) to guide the light energy to the capture, tracking, and alignment module 2.

[0034] In the preferred embodiment of the present application, the UAV 1 further comprises an energy storage battery 111 and a laser battery 110, and the second optical switch 105 is specifically used for: When the COM end and the P2 end of the second optical switch 105 are in communication, the energy optical signal flows to the laser battery 110 through the second optical switch 105, and the energy optical signal is converted into electrical energy by the laser battery 110 and used to charge the energy storage battery 111, so as to realize the energy supply of the UAV 1; wherein the COM end of the second optical switch 105 is connected with the P2 end of the first wavelength division multiplexer 107, the P2 end of the optical switch is connected with the laser battery 110, and the laser battery 110 is further connected with the energy storage battery 111.

[0035] In the preferred embodiment of the present application, the UAV 1 further comprises the circulator 109, and the second optical switch 105 is specifically used for: When the COM end and the P1 end of the second optical switch 105 are in communication, the energy optical signal flows to the circulator 109 through the second optical switch 105, and is sequentially forwarded to the third wavelength division multiplexer 108 through the P1 and P2 ports of the circulator 109, and is forwarded to the capture, tracking, and alignment module 2 by the third wavelength division multiplexer 108, so as to construct the weapon system or supply energy to the friendly unit UAV 1; The P1 end of the circulator 109 is connected with the P1 end of the second optical switch 105, and the P2 end of the circulator 109 is connected with the P2 end of the third wavelength division multiplexer 108. The circulator 109 outputs light from the P2 end when the light enters from the P1 end, and outputs light from the P3 end when the light enters from the P2 end.

[0036] In the embodiment, the P3 end of the circulator 109 is connected with the laser cell 110. When the external light energy is received by the capturing, tracking and aligning module 2, the external light energy is forwarded to the circulator 109 through the third wavelength division multiplexer 108, and then is sent to the laser cell 110 through the P2 and P3 ends of the circulator 109, so as to realize the energy supply to the unmanned aerial vehicle 1.

[0037] Preferably, the first optical switch 104 and the second optical switch 105 are one of a mechanical switch, a MEMS (Micro-Electro-Mechanical System) switch and a magneto-optical switch.

[0038] Specifically, the laser cell 110 is connected with the spool 3. The spool 3 contains a long optical fiber inside. During the flight of the unmanned aerial vehicle 1, the optical fiber of the spool 3 is continuously thrown out. The energy transmission laser 403 located outside the unmanned aerial vehicle 1 is connected with the second side of the spool optical fiber 301. The optical fiber plays a role of transmitting laser energy and communication light. The present application uses the optical fiber as a transmission medium to achieve the purpose of energy transmission. Before the optical fiber is physically disconnected, the unmanned aerial vehicle 1 can continuously be supplied with energy, so that the endurance of the unmanned aerial vehicle 1 is greatly improved.

[0039] Specifically, the light-sensitive surface of the laser cell 110 faces the first side of the optical fiber. The laser cell 110 is fixed with the first side of the optical fiber through a structural member, and the output light energy of the optical fiber is ensured to be accepted by the laser cell 110 with low loss through the adjustment coupling. The fixing forms include but are not limited to assembly, welding and bonding. The second side of the spool optical fiber 301 is connected with the energy transmission laser 403 through fusion.

[0040] Specifically, the laser cell 110 and the optical fiber adopt the coupling mode to optimize the energy conversion efficiency of the laser cell 110. The relative position and the relative angle of the optical fiber and the laser cell 110 are judged by monitoring the current of the laser cell 110. The higher the current is, the better it is. When the maximum current is obtained, it is fixed, so that the energy loss of the energy transmission device can be reduced.

[0041] Furthermore, a lens can be added in front of the light-sensitive surface of the optical fiber to the laser cell 110 to realize the collimation of the optical fiber light. The collimated light spot will have a reduced sensitivity to the distance, so that the adjustment difficulty is reduced.

[0042] In the embodiment, the energy transmission laser 403 is connected to the second side of the spool optical fiber 301 by fusion, which can reduce energy loss and avoid link damage risk. Because the optical power in the energy transmission optical fiber is strong, and the energy density is high, if the conventional optical fiber connector is used for connection, the optical fiber end face is easily damaged by dust, water vapor and other foreign matters, or the end face is damaged by the transmitted light energy.

[0043] In the embodiment, the first bidirectional optical module 103 and the second bidirectional optical module 402 can separate the input and output light by wavelength division multiplexing technology, or use a circulator 109. The wavelength division multiplexing technology requires that the wavelengths of the transmitted and received light are different, but the circulator 109 does not require that the wavelengths are different, but the cost of the circulator 109 is high.

[0044] In the embodiment, the sensor module 102 includes but is not limited to a visible light camera module, an infrared light camera module, and a laser radar.

[0045] Further, some optical devices can use hybrid devices, for example, the first wavelength division multiplexer 107 can be integrated with the second optical switch 105, further reducing the size of the energy transmission device.

[0046] Further, to prevent external strong light from entering the bidirectional optical module and damaging the PD (photodiode) in the bidirectional optical module when the first bidirectional optical module 103 is connected to the capture, tracking and alignment module 2, or the second bidirectional optical module 402 is connected to the capture, tracking and alignment module 2, a light power monitoring device, such as a coupler and a photodiode, can be added to the COM end of the third wavelength division multiplexer 108. The coupler separates a small part of the light, and the photodiode converts the light signal into an electrical signal, which is then processed by the main control circuit, thereby achieving power monitoring. When the power is found to be too strong, the third optical switch 106 can be driven to be in a non-set state, thereby protecting the first bidirectional optical module 103 or the second bidirectional optical module 402.

[0047] The working principle of the present application will be described in detail in combination with a specific application scenario.
