Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to an UAV optical fiber guidance system integrating optical fiber inertial combined navigation. Background Art

[0002] With the rapid development of drone technology, its applications in various fields are becoming increasingly widespread. However, traditional drone wireless communication technologies, such as Bluetooth and 2.4G frequency band communication, are susceptible to interference from external radio waves. Furthermore, due to long transmission distances and signal attenuation in the air, wireless control has a certain degree of delay.

[0003] To overcome the above problems, fiber optic guidance technology has emerged. Fiber optic guidance technology has the advantages of strong anti-interference ability, large transmission bandwidth, and low latency. It can shield electromagnetic interference and improve control sensitivity in complex environments. However, existing fiber optic guidance systems for drones still have some problems:

[0004] First, drone flight navigation relies on satellite signal systems and its own flight control inertial navigation system, and the wireless signal transmission mode is unstable.

[0005] Second, existing fiber-optic guidance systems utilize internal wiring. While they utilize an interference-resistant fiber-optic signal transmission mode, which provides immunity to wireless interference, the drone's navigation still relies on its own GPS positioning system and the flight control's own inertial MEMS navigation system. If the GPS signal is lost, the flight control's own inertial navigation MEMS will continue to accumulate errors due to its inherent precision. This can cause the drone to continue to lose accuracy and experience navigational deviations while using fiber-optic guidance. This prevents the high precision and interference resistance inherent in fiber-optic guidance from being fully utilized.

[0006] Third, the fiber optic reels of mainstream drones using internal cable exit technology are prone to collapse, causing tangles. Even with internal cable exit, the cable still tends to clump, leading to fiber entanglement. Furthermore, the fiber guidance range of existing internal cable reels is difficult to match the flight ranges of different drone models, which can easily lead to redundant fiber reel ends and increase the drone's payload.

[0007] To address the above problems, the present invention proposes a fiber-optic guidance system for drones that integrates fiber-optic inertial combined navigation. The fiber-optic receiving end integrates high-precision fiber-optic gyroscopes, quartz flexible accelerometers, GNNS receivers and other sensors. With the support of a high-precision fiber-optic inertial navigation system, it can resist wireless signal interference, assist in compensating for the accumulated errors of the drone's own navigation system, and support the drone's fully autonomous flight. Summary of the Invention

[0008] The purpose of the present invention is to provide a fiber-optic guidance system for unmanned aerial vehicles (UAVs) that integrates fiber-optic inertial combined navigation. The system assists the autonomous flight of UAVs through an integrated fiber-optic inertial combined navigation system and a fiber-optic anti-interference system, achieving high modularity and compatibility with most types of UAVs. The system also adopts a fiber-optic internal pay-off process that uses a coil fixed with glue to achieve tangle-free and reliable fiber-optic internal pay-off. Furthermore, the system achieves closed-loop control by transmitting optical terminal signals in a two-way manner with the UAV flight control system and bidirectionally connecting the transmitting optical terminal signals to a ground control terminal.

[0009] To achieve the above objectives, the present invention provides a fiber-optic guidance system for unmanned aerial vehicles (UAVs) that integrates fiber-optic inertial combined navigation, including a fiber-optic inertial combined navigation system and a fiber-optic anti-interference system:

[0010] The fiber optic anti-interference system includes a transmitting optical terminal, a receiving optical terminal and a fiber optic tube; the fiber optic inertial integrated navigation system includes a fiber optic gyroscope, a quartz flexible accelerometer and a GNSS receiver, and the components are integrated into the transmitting optical terminal;

[0011] The transmitting optical terminal is fixed to one end of the optical fiber tube, and is composed of a transmitting optical end cover, a transmitting optical end bottom cover and an internal circuit board, and the transmitting optical terminal is connected to the ground control end through an optical fiber;

[0012] The optical fiber barrel is fixed to the drone through a wire constraint and includes a barrel body, a wire outlet, a barrel cover, a shaft sleeve, and a barrel shaft. The optical fiber is embedded in the barrel body in the form of a wire coil with a hollow interior. The shape is fixed by potting glue, and the wire is released by an internal pay-off method. The barrel shaft is used to keep the wire coil hollow and prevent it from collapsing during the solidification of the potting glue. The wire outlet is located at the other end of the optical fiber barrel, opposite the transmitting optical terminal.

[0013] The physical interfaces of the transmitting optical terminal include network port, serial port, TTL and HDMI.

[0014] In one possible implementation, wired signal transmission is performed between the transmitting optical terminal and the UAV flight control through a serial port, and the transmitted signal includes the UAV attitude and position feedback signal of the inertial integrated navigation system of the transmitting optical terminal.

[0015] In one possible implementation, the receiving optical terminal includes a photoelectric conversion module; ground personnel convert the control signal from an electrical signal to an optical signal through the photoelectric conversion module, and transmit it to the transmitting optical terminal via the optical fiber; the transmitting optical terminal converts the optical signal into an electrical signal, and then transmits it to the UAV flight control through the serial port.

[0016] In one possible implementation, the transmitting optical terminal receives image information from the UAV and synchronizes the image information to the ground control terminal.

[0017] In a possible implementation, the light emitting end cover and the light emitting end bottom cover are riveted together to protect a sensor module, wherein the sensor module includes a GNNS receiver, a fiber optic gyroscope, and a quartz flexible accelerometer.

[0018] In a possible implementation, HDMI is the main interface of the image transmission module.

[0019] In a possible implementation, the optical fiber tube can be provided in different models and be compatible with a transmitting optical terminal.

[0020] In one possible implementation, the ground control terminal directly intervenes to control the autonomous flight of the UAV.

[0021] In one possible implementation, the fiber optic inertial navigation system is independent of the drone's own navigation system and is embedded in the drone's fiber optic guidance system.

[0022] In one possible implementation, the optical fiber tube adopts an internal pay-out method. Its manufacturing process uses potting glue to fix the shape of the optical fiber coil to prevent the coil from collapsing. During the solidification process of the potting glue, the shape of the optical fiber coil is fixed by the tube axis, making the optical fiber coil hollow inside. When the drone is flying, the optical fiber coil is pulled out from the internal hollow part and connected to the ground control end through the outlet, so that the wire is output from the inside to prevent entanglement.

[0023] Therefore, the present invention adopts the above-mentioned fiber-optic inertial combined navigation UAV optical fiber guidance system, which has the following technical effects:

[0024] (1) The fiber optic guidance system for UAVs of the present invention not only integrates the aircraft and the optoelectronic information conversion module, but also integrates the fiber optic inertial combined navigation system, which can detect and compensate the attitude and position information of the UAV and the carrier in real time.

[0025] (2) The fiber-optic inertial combined navigation system of the present invention, with the high precision of the fiber-optic gyroscope and the quartz flexible accelerometer, feeds back the attitude and position information to the UAV flight control, assisting the UAV to compensate for the accumulated error of its own inertial navigation and assisting in adjusting its own flight attitude, thus achieving completely autonomous flight without human intervention; at the same time, with the help of the fiber-optic guidance system, the ground control end can directly intervene in the autonomous flight of the UAV to ensure the control of the UAV.

[0026] (3) The fiber-optic inertial combined navigation system and fiber-optic anti-interference system of the present invention, as well as the flight control and inertial navigation system of the UAV itself, form a closed-loop control. In a narrow sense, the UAV flight control, the fiber-optic inertial combined navigation system, and the ground control end are all wired connections through two-way signal transmission. This closed-loop control has extremely strong anti-interference capabilities, enabling the fiber-optic guidance system to shield interference from wireless signals, thereby ensuring low latency and high precision of manual control.

[0027] (4) The fiber-optic guidance system for unmanned aerial vehicles (UAVs) integrated with fiber-optic inertial navigation of the present invention is highly integrated and modularized, and has greater portability. By embedding the transmitting optical terminal and fixing it to the optical fiber tube, it is not only suitable for UAVs but also for mobile terminals such as underwater submersibles.

[0028] (5) The fiber optic tube of the present invention adopts a modular design, which is more flexible. It can replace the tube body of different sizes according to the model of the UAV, and set the fiber optic tube to different fiber optic capacity to meet the needs of common UAV models. At the same time, it is compatible with the transmitting optical terminal, and the outlet can be replaced according to the model of the fiber optic tube, which is more practical.

[0029] (6) The optical fiber internal payout method of the present invention can prevent the optical fiber from being tangled during the lead-out process, fix the wire coil by potting glue to prevent the wire coil from collapsing, maintain the shape of the wire coil by the barrel shaft during the glue solidification process, take out the wire coil after solidification so that the inside of the wire coil is hollow, place the wire coil in the barrel body, and the optical fiber is led out from the hollow part through the wire outlet due to the traction force, thereby realizing internal payout.

[0046] The present invention can be explained in more detail by the following examples. The purpose of disclosing the present invention is to protect all changes and improvements within the scope of the present invention. The present invention is not limited to the following examples.

[0047] See 1 to Figure 11 The present invention provides a fiber-optic guidance system for unmanned aerial vehicles (UAVs) that integrates fiber-optic inertial navigation. The system comprises two major systems: a fiber-optic anti-interference system and a fiber-optic inertial navigation system. The fiber-optic anti-interference system primarily comprises a transmitting optical terminal 2, a receiving optical terminal, and a fiber optic tube 01. The fiber-optic inertial navigation system primarily comprises a fiber-optic gyroscope, a quartz flexible accelerometer, and a GNSS receiver, all integrated into the transmitting optical terminal 2.

[0048] The transmitting optical terminal 2 consists of a transmitting optical end cover 21, a transmitting optical end bottom cover 22, and an internal circuit board. The transmitting optical end cover 21 and the transmitting optical end bottom cover 22 are fixed to the optical fiber tube body 1 by screws. The transmitting optical terminal 2 is fixed to one end of the optical fiber tube body 1 and is a highly integrated module. Its circuit board integrates a fiber optic gyroscope, a quartz flexible accelerometer, a GNNS receiver, and an image transmission module. The physical interfaces of the transmitting optical terminal 2 include a network port, a serial port, TTL, and HDMI. Its main hardware is integrated into the transmitting optical terminal 2. The HDMI interface is the main interface of the image transmission module. The serial port is used for wired signal transmission between the transmitting optical terminal 2 and the drone flight control. The transmitted signal includes the drone attitude and position feedback signal of the inertial integrated navigation system of the transmitting optical terminal 2.

[0049] The specific implementation of the optical fiber anti-interference system is as follows:

[0050] Fiber optic tube 01 is secured to the drone via a wire restraint. One end of the tube is screwed to the transmitting optical terminal 2, and the other end is screwed to the cable outlet 3. The hollow body 1 of the fiber optic tube 01 houses the fiber coil and protects the internal fiber from damage.

[0051] The UAV flight control system is connected to the serial port of optical transmitter 2. Ground personnel use the optical converter module of the optical transmitter to convert the control signal from an electrical signal to an optical signal. This signal is then transmitted through the optical fiber of optical fiber tube 01 to optical transmitter 2. Optical transmitter 2 converts the optical signal into an electrical signal and transmits it to the flight control system through the serial port. This process enables direct control of the UAV from the ground.

[0052] Currently, drones primarily rely on the Global Navigation Satellite System (GPS) and the flight control's own inertial navigation system (MEMS) to maintain attitude control and position navigation. If a drone briefly loses GPS signal, the flight control's inertial navigation system will calculate and compensate for the drone's position, maintaining flight navigation for a short period of time. If the GPS signal is continuously lost, the flight control's inertial navigation system will accumulate position deviations due to measurement and calculation errors, causing the drone to deviate from its navigation target.

[0053] The fiber optic gyroscope integrated into the fiber optic anti-interference system of the present invention does not replace the inertial navigation system of the UAV. Instead, it relies on high-precision fiber optic signal transmission and the serial port connection between the transmitting optical terminal 2 and the flight control of the UAV to use the high-precision signal measured by the fiber optic inertial combined navigation system to compensate for the accumulated deviation of the UAV's own inertial navigation, assist the UAV flight control to adjust its own flight attitude, and achieve high-precision, fully autonomous flight without human intervention.

[0054] The specific implementation methods of the closed-loop control of the fiber-optic inertial integrated navigation system and the fiber-optic guidance system based on fiber-optic inertial navigation are as follows:

[0055] In the presence of a GPS signal, the fiber-optic gyroscope and quartz flexible accelerometer of the fiber-optic inertial navigation system record the attitude information of fiber optic tube 01 in real time. The GNNS receiver is responsible for receiving this position information. Because fiber optic tube 01 and the drone are constrained by a line, the attitude and position information of fiber optic tube 01 are approximately the same as those of the drone. After collecting this information, the optical transmitter 2 transmits it to the drone's flight control system via a serial port, assisting the drone in performing attitude and position compensation and correction. Simultaneously, the drone's flight control information and fiber-optic inertial navigation system signals are transmitted to the ground control system via a fiber-optic anti-interference system, forming a closed-loop control loop with manual control on the ground.

[0056] In the absence of a GPS signal, the fiber-optic gyroscope (FOG) in the FIBER-INDITAL navigation system continues to record the drone's angular velocity from the point where the GPS signal is lost. It then integrates the deceleration to infer the drone's heading change and feeds this information back to the drone's flight control system, assisting in attitude and position compensation. Because the FOG's accuracy far exceeds that of the drone's own inertial navigation, and due to the interference resistance of fiber-optic guidance, the FIBER-INDITAL navigation system's attitude and position compensation allows the drone to continue autonomous navigation even in the absence of a GPS signal. This process eliminates the need for human intervention, particularly in mine tunnels and areas with signal loss. Similarly, thanks to the integrated fiber-optic guidance, the ground receiver can directly intervene and receive control of the drone's autonomous flight.

[0057] In addition, the transmitting optical terminal 2 simultaneously receives image information from the UAV and synchronizes the information to the ground control terminal.

[0058] The optical transmitter 2 is highly modular and can be connected to various types of optical fiber tubes 01. The optical transmitter cover 21 and the optical transmitter bottom cover 22 are riveted together to prevent external forces from damaging the circuit board and protect the sensor modules such as the GNNS receiver, fiber optic gyroscope, and quartz flexible accelerometer.

[0059] The optical fiber tube 01 consists of a tube body 1, an outlet 3, a tube cover 4, a shaft sleeve 5 and a tube shaft 6, and is fixed on a drone or other carrier such as an underwater submersible. Taking into account the wide variety of current drone models and the different actual usage scenarios, in other embodiments, the optical fiber tube 01 can flexibly change the size of the optical fiber tube 01 according to the drone's range, avoiding redundancy of optical fibers and causing the drone and carrier to carry excess weight. According to the cruising capabilities of mainstream drone models on the market, the optical fiber tube 01 is set to accommodate optical fiber lengths of 1KM, 2KM, 5KM, 10KM, 15KM, 20KM, 25KM and 30KM, which can quickly deploy various types of optical fiber tubes 01 according to user needs, making them more targeted and practical. The above-mentioned types of optical fiber tubes are also compatible with the transmitting optical terminal 2, with a higher degree of modularity.

[0060] The funnel-shaped outlet 3 of the fiber optic tube 01 is fixed to the tube cover 4 of the fiber optic tube 01. This effectively prevents the fiber from drifting and getting caught in the drone's propellers during payout, causing entanglement. The present invention uses a 5-10 km type outlet 3, which is compatible with all the above-mentioned fiber optic tube 01 models.

[0061] The optical fiber uses an ultra-thin single-mode bare optical fiber with a diameter of 0.25mm. The transmission loss of the single-mode optical fiber is about 0.35dB / km, and the transmission loss of the optical signal at a wavelength of 1550nm is less than 0.21dB / km.

[0062] The present invention also provides a new optical fiber pay-off process, see Figure 10 and Figure 11 The optical fiber tube 01 adopts an internal pay-off method to output the wire, and an optical fiber coil is embedded in it. The shape of the optical fiber coil is fixed by potting glue to prevent the coil from collapsing. During the solidification process of the potting glue, the tube shaft 6 is used to fix the shape of the optical fiber coil when the potting glue in the tube body 1 solidifies, and the tube shaft 6 is taken out until the glue solidifies, so that the inside of the coil is hollow. The shaft sleeve 5 is used to fix the tube shaft 6 so that it rotates smoothly.

[0063] When the drone is flying, the optical fiber is led out from the hollow part of the optical fiber coil due to the traction force. This kind of cable outlet is called internal cable outlet, and then connected to the ground control end through the cable outlet 3. This cable outlet method can effectively prevent the optical fiber from being entangled and damaged by external forces.

[0064] The fiber-optic inertial navigation system is independent of the drone's own navigation system and is embedded in the drone's fiber-optic guidance system. This design makes the internal-line drone fiber-optic guidance system more portable and modular.

[0065] Therefore, the present invention adopts the above-mentioned fiber-optic guidance system for unmanned aerial vehicles (UAVs) with integrated fiber-optic inertial combined navigation, which has extremely strong anti-interference ability through fiber-optic guidance and signal transmission. A fiber-optic inertial navigation system integrated in the transmitting optical terminal is set up, which can measure and compensate for the attitude error and position error of the UAV flight control, assist the UAV in autonomous flight, achieve high modularity, and be compatible with most models of UAVs.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solutions of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
