Description

Technical Field

[0001] The invention relates to a photoelectric integrated conversion module for an unmanned aerial vehicle. Background Art

[0002] With the widespread application of drones in the market, their use of radio for control is easily affected by electromagnetic and environmental interference, and at the same time, it affects the real-time performance of signals transmitted back to the ground control station and the high definition of images. Especially in scenarios where real-time transmission is required for short-distance applications such as aerial photography and videography, inspection / surveillance, agricultural monitoring, meteorology, security and inspection, exploration, and mapping, they are unable to provide highly stable and high-quality aerial videos and photos, affecting their use effect.

[0003] Fiber optic communication, as a transmission medium that is immune to electromagnetic interference, is an innovative technology when combined with drones. This technology utilizes fiber optics as a high-speed, low-latency data transmission medium, shielding drone control signals from external environmental and electromagnetic interference. High-definition video signals are also transmitted back to the ground control station in real time, providing an immersive flight experience. Fiber optic transmission, with its ultra-large bandwidth, strong anti-interference properties, and extremely low latency, has significantly enhanced the performance and application scope of drones.

[0004] The optical fiber module is located between the drone and the ground system, secured to the drone using specialized tooling. The fiber optic module outlets are located at the front and rear ends of the module. The optical fibers at each end are connected to the optoelectronic conversion modules on the drone and ground systems, respectively, via optical fiber connectors. These optical fibers are converted into electrical signals, which are then connected to the drone and ground systems via connecting cables. The drone system converts the video signals, drone attitude, and payload status signals captured by the drone's camera into optical signals, which are then transmitted to the ground system via optical fiber. The ground system converts the optical signals back into electrical signals, decodes them, and displays the video signals on a display. Simultaneously, the ground system converts flight control signals into optical signals, which are transmitted to the drone system via optical fiber. The drone system then converts the optical signals back into electrical signals to control the drone's attitude and payload status. Optical fiber transmission not only supports HD and even UHD video transmission but also effectively resists electromagnetic interference, ensuring stable signal transmission.

[0005] like Figure 1As shown, the traditional fiber optic module outputs the fiber in a front-to-back manner. The optical fiber exposed at the rear end of the fiber optic module is connected to the coupler on the optoelectronic conversion module mounted on the drone through a connected optical fiber connector, and the two are tightly coupled together by threads. Because the rear end of the fiber optic module faces forward during flight, the exposed optical fiber will be affected by wind and there is a risk of fiber breakage and damage or failure of the optical fiber connector, which will affect the normal transmission of the signal. In addition, each module is separate and occupies a relatively large space. The cables in the middle are often more messy, and the overall wiring needs to occupy the already limited space of the drone. The fiber optic modules fixed on the drone are mostly fixed to the drone with professional tooling. Installation and removal are time-consuming and labor-intensive. Although there are also methods of bundling with tape or cable ties, the reliability is not high. There is a risk of the drone falling off during flight. In addition, the bottom of both fixing methods has no support. The bottom of the drone must be placed on a supported surface before taking off.

[0006] Therefore, in order to solve the above problems, an optoelectronic conversion module was designed that occupies a small space on the drone and can be quickly installed. Summary of the Invention

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0039] Figure 1 In the existing technology, the fiber optic module 2 uses the traditional front-to-back fiber outlet method. The optical fiber exposed at the rear end of the optical fiber module 2 is connected to the coupler 9 on the photoelectric conversion module mounted on the drone 1 through the connected optical fiber connector 7, and the two are tightly coupled together by threads. Because the rear end of the optical fiber module 2 faces forward during flight, the exposed optical fiber is affected by wind and there is a risk of fiber breakage, damage or failure of the optical fiber connector 7, etc., thereby affecting the normal transmission of signals;

[0040] The optical fiber module 2 fixed on the drone 1 has a circular cylindrical shape. Currently, the method of fixing the drone 1 is to use a cable tie 8 or tape to tie the optical fiber module 2 to the bottom of the drone 1, or to add a clamp to the bottom of the drone 1 and fasten the outer shell of the optical fiber module 2 with bolts. The former is not firmly fixed due to the shape of the optical fiber module 2 and there is a risk of it falling off during flight. The latter requires professional tools, and installation and removal are time-consuming and labor-intensive. Both have the same defect, that is, after the optical fiber module 2 is loaded on the bottom of the drone 1, the bottom has no support, and the bottom of the drone 1 must be placed on a supported surface before it can take off.

The other end of the optical fiber module 2 is connected to the optoelectronic component on the ground.

[0043] The optoelectronic conversion module in this embodiment is mainly used on the drone 1, which is mainly composed of an optical fiber module 2 and an optoelectronic conversion module 3, and the optoelectronic conversion module 3 is integrated at the fiber output end of the optical fiber module 2, so that both ends of the optical fiber in the optical fiber module 2 are output from the same end, avoiding the risk of fiber breakage due to the influence of wind when the optical fiber is exposed to the outside of the drone 1 when connected to the optoelectronic conversion module 3 on the drone 1, thereby ensuring the normal transmission of the signal.

[0044] Specifically, the optical fiber module 2 includes an outer tube 21, an inner core 22, a fiber outlet tube 23 and a fiber outlet nozzle 24. The inner core 22 is arranged in the outer tube 21.

The inner core 22 is installed in the outer tube 21. The inner core 22 is mainly composed of a first baffle 221, a rewound optical fiber 222 and a second baffle 223. The rewound optical fiber 222 is fixed on the optical fiber rewinding machine by the first baffle 221 and the second baffle 223. The optical fiber is wound around the cylinder with a through hole in the middle of the two and fixed with glue into a semi-solidified state to make it the inner core 22. The second baffle 223 is installed on the outer tube 21. The fiber outlet tube 23 is installed on the second baffle 223. The fiber outlet nozzle 24 is fixed on the end of the fiber outlet tube 23 away from the second baffle 223 to form a preliminary optical fiber module 2 (excluding the optical fiber connectors 7 at both ends of the optical fiber), and the optical fiber inside the inner core 22 can be led out through the fiber outlet tube 23 and the fiber outlet nozzle 24.

[0046] Furthermore, the outer cylinder 21 is a cylindrical structure with an open front end and a hollow interior. An inner convex ring 211 for supporting the first baffle 221 is provided at the inner bottom of the outer cylinder 21 , and six protruding first hole columns 212 are evenly distributed on the side of the open end of the outer cylinder 21 .

[0047] In this embodiment, the outer cylinder 21 is designed to be a cylindrical structure with an open front end and a hollow interior so that the inner core 22 can be installed into the outer cylinder 21. An inner convex ring 211 for supporting the first baffle 221 is provided at the bottom of the outer cylinder 21 so as to press the inner core 22 and the outer cylinder 21 tightly. Six protruding first hole columns 212 are evenly distributed on the side of the open end of the outer cylinder 21 so that the remaining components can be fixedly connected through the first hole columns 212.

[0048] Furthermore, the first baffle 221 and the second baffle 223 are both circular plate structures, and a first through hole 2231 is provided in the center of the first baffle 221 and the second baffle 223. The outer wall of the second baffle 223 is symmetrically provided with six annular hole grooves 2232 that match the first hole column 212. The second baffle 223 is provided with a fiber outlet 2233 near the annular hole grooves 2232. The second baffle 223 is evenly provided with a number of first mounting holes 2234 near the first through hole 2231. One end of the fiber outlet tube 23 is provided with a second mounting hole 231 that matches the first mounting hole 2234.

[0049] In this embodiment, the first baffle 221 and the second baffle 223 are designed to be circular plate structures so as to better clamp and fix the rewound optical fiber 222. A first through hole 2231 is provided in the center of the first baffle 221 and the second baffle 223 for winding and leading out the optical fiber. Six annular hole grooves 2232 are symmetrically provided on the outer wall of the second baffle 223 that match the first hole column 212 so that the second baffle 223 is fixedly installed on the outer cylinder 21. A fiber outlet 2233 is provided at a position of the second baffle 223 near the annular hole groove 2232 so that the optical fiber outside the inner core 22 can pass through the fiber outlet 2233. Four first mounting holes 2234 are evenly provided at a position of the second baffle 223 near the first through hole 2231. A second mounting hole 231 that matches the first mounting hole 2234 is provided on one end side plate of the fiber outlet tube 23 so that the fiber outlet tube 23 can be fixedly installed by screws. On the second baffle 223, the first through hole 2231 on the second baffle 223 is connected to the fiber outlet tube 23, so that the optical fiber inside the inner core 22 passes through the first through hole 2231 on the second baffle 223 and enters the fiber outlet tube 23, is led out by the fiber outlet mouth 24 on the fiber outlet tube 23, and is finally connected to the optoelectronic component at the ground end through the optical fiber connector 7. In this embodiment, the fiber outlet tube 23 of the optical fiber module 2 of the prior art is cleverly integrated with the optoelectronic conversion module 3, so that the optical fibers at both ends of the optical fiber module 2 are output at the same end, one end of the optical fiber inside the inner core 22 is output from the first through hole 2231 of the second baffle 223, and one end of the optical fiber outside the inner core 22 is output from the fiber outlet mouth 2233 of the second baffle 223. The optoelectronic conversion module 3 with the outer shell removed is integrated with the optical fiber tube, thereby avoiding the optical fiber exposed at the front end from being broken due to the influence of wind during the flight of the drone 1, thereby affecting the normal transmission of the signal.

[0050] Specifically, the photoelectric conversion module 3 includes a bottom shell 31 , a photoelectric conversion assembly 32 and a cover plate 33 . The bottom shell 31 is disposed on the optical fiber module 2 , the photoelectric conversion assembly 32 is disposed in the bottom shell 31 , and the cover plate 33 is disposed on the bottom shell 31 .

[0051] The photoelectric conversion module 3 is mainly composed of a bottom shell 31, a photoelectric conversion component 32 and a cover plate 33. The bottom shell 31 is installed on the second baffle 223 of the optical fiber module 2. The photoelectric conversion component 32 is installed inside the bottom shell 31. The cover plate 33 is also installed on the bottom shell 31, which plays a certain protective role to prevent dust from entering the bottom shell 31 after outdoor use and affecting subsequent normal use. In this embodiment, the photoelectric conversion module 3 is integrated into the excess space in the direction of the fiber outlet tube 23 of the optical fiber module 2, so that the photoelectric conversion module 3 and the optical fiber module 2 are combined into an integrated module, that is, photoelectric conversion is directly performed in the integrated module, and the connection with the drone 1 end is connected through a communication cable assembly. There is no need for the optical fiber to be exposed on the outside and connected to the drone 1 end. It is not only convenient for disassembly and assembly, but also avoids the risk of fiber breakage caused by wind during flight of the drone 1. At the same time, since the connection between the photoelectric conversion module 3 and the optical fiber module 2 is completed in the bottom shell 31, the overall wiring is more reasonable, and the space occupied by the photoelectric conversion module 3 and the optical fiber module 2 is reduced.

[0052] Furthermore, the bottom shell 31 is in the shape of a cylinder with one side cut off, a second through hole 311 is provided in the center of the bottom shell 31, a fiber winding tube 312 is provided on the outer edge of the second through hole 311, four positioning hole columns 313 are evenly distributed on the outer wall of the bottom shell 31, a waist hole 314 is provided on the inner wall of the bottom shell 31, a plurality of second hole columns 315 are provided on the inner bottom wall of the bottom shell 31, and a third mounting hole 331 is provided on the cover plate 33 to match the second hole column 315.

A fiber winding tube 312 is provided at the outer edge of the second through hole 311 so as to wind the excess optical fiber. Four positioning holes 313 are evenly distributed on the outer wall of the bottom shell 31 so as to install the bottom shell 31 on the second baffle 223. A waist hole 314 is provided on the inner wall so that the optical fiber led out from the fiber outlet 2233 passes through the waist hole 314 to enter the bottom shell 31 and is connected to the optoelectronic conversion component 32 through the optical fiber connector 7. Five second hole columns 315 are provided on the inner bottom wall of the bottom shell 31, and two third mounting holes 331 that match the second hole columns 315 are provided on the cover plate 33. The three second hole columns 315 are used to fix the optoelectronic conversion component 32, and the remaining two are used to fix the cover plate 33. It should be noted that a through hole for the fiber outlet tube 23 to pass through is also provided in the center of the cover plate 33.

[0054] Furthermore, balancing bars 4 are symmetrically provided on the upper and lower sides of the outer cylinder 21 .

[0055] This embodiment also has four balance bars 4 symmetrically installed on the upper and lower sides of the outer cylinder 21. When the optoelectronic conversion module is installed on the end of the drone 1 using a cable tie 8 or tape, the balance bars 4 on the outer cylinder 21 can be attached to the bottom end surface of the drone 1 to increase the reliability of the connection between the optoelectronic conversion module and the end of the drone 1. When the drone 1 takes off and lands, the balance bars 4 can directly contact the ground, playing a certain balancing and supporting role.

[0056] Furthermore, the drone 1 is provided with a bracket 5 , the bottom of the bracket 5 is provided with a support foot 6 , and the bottom of the outer tube 21 is provided with a blind hole 213 that matches the bracket 5 .

[0057] like Figure 14 As shown, in other embodiments, a bracket 5 can be symmetrically installed at the bottom of the drone 1 end, and a blind hole 213 that matches the bracket 5 can be provided at the bottom of the outer tube 21. One end of the bracket 5 is connected to the bottom of the outer tube 21 by a screw, and the other end of the bracket 5 can be synchronously fixedly installed on the bottom shell 31 of the photoelectric conversion module 3, thereby increasing the reliability of the connection between the outer tube 21 and the drone 1, and a support foot 6 is also provided at the bottom of the bracket 5 to play a certain supporting role, so as to facilitate the take-off and landing of the drone 1.

[0058] When in use, first, one end of the optical fiber inside the inner core 22 is pulled out from the first through hole 2231 of the second baffle 223, and one end of the optical fiber outside the inner core 22 is pulled out from the fiber outlet 2233 of the second baffle 223, and the entire inner core 22 is placed in the outer cylinder 21, and then one end of the optical fiber inside the inner core 22 is passed through the fiber outlet tube 23 and led out from the fiber outlet nozzle 24, and the fiber outlet tube 23 is installed on the second baffle 223 by screws, and then the end of the optical fiber that passes through the fiber outlet 2233 is passed through the waist hole 314 on the bottom shell 31 and inserted into the bottom shell 3 1, and make an optical fiber connector 7 at the end of the optical fiber, and the excess optical fiber is wound on the outer wall of the fiber winding tube 312. The optical fiber connector 7 is inserted into the optical port position of the pre-installed photoelectric conversion component 32, and the photoelectric signal is converted into an electrical signal interface. The cover plate 33 is installed and fastened to the bottom shell 31 with screws. After the installation is completed, the bottom shell 31 and the second baffle 223 are installed together with the bolts into the first hole column 212 of the outer cylinder 21 to completely install the photoelectric conversion module 3 on the optical fiber module 2. The optical fiber led out of the fiber outlet 24 is fused with light. The pigtail of the optical fiber connector 7, or the optical fiber connector 7 can be directly made into an optoelectronic conversion module; after the optoelectronic conversion module is assembled, it can be fixed to the drone 1 end by a cable tie 8, tape or bracket 5, and the electrical signal interface on the optoelectronic conversion module is connected to the electrical signal interface on the drone 1 end through a communication cable assembly, and the optical fiber led out from the fiber outlet 24 of the optoelectronic conversion module is connected to the optoelectronic component at the ground end through the optical fiber connector 7. During flight, the drone 1 end is responsible for converting the video signal captured by the camera on the drone 1, the drone 1 attitude and load status signal into an optical signal, and transmitting it to the ground end through the optical fiber. The ground end is responsible for converting the optical signal back into an electrical signal, and decoding the video signal to display it on the display screen; at the same time, the ground end is responsible for converting the flight control signal into an optical signal, and transmitting it to the drone 1 end through the optical fiber. The drone 1 end is responsible for converting the optical signal back into an electrical signal to control the drone 1 attitude and load status. Optical fiber transmission not only supports high-definition and even ultra-high-definition video transmission, but also can effectively resist electromagnetic interference to ensure stable signal transmission.
