Description

Technical Field

[0001] This invention relates to the field of data transmission technology, and in particular to a method for remote transmission and identification processing of RID for unmanned aerial vehicles (UAVs). Background Technology

[0002] Remote identification (RID) of unmanned aerial vehicles (UAVs) is a core foundational technology for low-altitude flight safety supervision. As the only onboard electronic identity for UAVs, it possesses the technical attributes of mandatory onboarding, non-shutdown capability, and full traceability. It is a core technical means to investigate illegal flights, regulate airspace order, and prevent low-altitude safety risks.

[0003] Currently, drone RID data transmission mainly employs two modes: broadcast (Bluetooth / Wi-Fi near-field), which has a short transmission distance, requires extensive ground receiving station construction, resulting in high investment costs and difficulty in covering mountainous, forested, and marine areas; and network (4G / 5G long-range), which is limited by the coverage of ground base stations, leading to transmission failures in remote areas without infrastructure, and creating regulatory blind spots in beyond-line-of-sight airspace. Neither mode can simultaneously achieve both low-latency, precise near-field control and seamless, far-field coverage. Summary of the Invention

[0004] In view of the above, the present invention aims to provide a method for remote transmission and identification processing of unmanned aerial vehicle (UAV) RID to solve the aforementioned technical problems.

[0005] The technical solution adopted in this invention is as follows: This invention provides a method for remote transmission and identification processing of unmanned aerial vehicle (UAV) RID, including: Configure a satellite communication module on the UAV's onboard terminal and connect it to the onboard RID module to establish a communication link between the UAV and the low-Earth orbit satellite constellation; The raw data output from the RID module is copied into a first data stream and a second data stream by the data distribution chip. The first data stream is encapsulated according to the terrestrial communication protocol, and the second data stream is encapsulated according to the satellite communication protocol. The signal parameters of the 4G / 5G link are detected at a preset fixed period. When the signal parameters are detected to be lower than a preset threshold for N consecutive detection periods, the satellite communication module is activated and the second data stream is transmitted. When the signal parameters are detected to be higher than the preset threshold, the satellite communication module is put into hibernation. The ground control platform receives data from ground links and satellite links, parses the data, and performs fusion processing using a unified spatiotemporal reference to output the identifier and flight parameters of each UAV.

[0006] Optionally, the preset fixed period is 100ms-200ms.

[0007] Optionally, when the satellite communication module is activated, the second data stream is baseband modulated, amplified by radio frequency, and transmitted to a low-Earth orbit satellite via an antenna. The low-Earth orbit satellite then forwards the data to a ground receiving station, which demodulates and parses the data to obtain the RID data.

[0008] Optionally, the radio frequency amplification includes primary amplification of the radio frequency unit and secondary amplification of the satellite antenna.

[0009] Optionally, the broadcast link corresponding to the terrestrial communication protocol remains operational throughout the entire process, the 4G / 5G link is the default priority link, and the satellite link is the backup link.

[0010] Optionally, the UAV RID remote transmission and identification processing method also includes: The information reporting cycle of the satellite communication module is set according to the real-time flight speed of the UAV, and the reporting cycle is negatively correlated with the flight speed.

[0011] Optionally, the fusion process includes: The system decrypts and analyzes multi-source data, removes outliers, registers spatiotemporal references, and normalizes and merges the data.

[0012] Optionally, the UAV RID remote transmission and identification processing method also includes: The satellite communication module receives navigation correction data and forwards it to the airborne navigation unit, as well as receives flight control commands and forwards them to the airborne flight control unit.

[0013] The above-described solution of the present invention has at least the following beneficial effects: The above-mentioned solution of the present invention includes: configuring a satellite communication module on the airborne end of the UAV and connecting it with the airborne RID module to establish a communication link between the UAV and the low-Earth orbit satellite constellation; copying the raw data output by the RID module into a first data stream and a second data stream through a data distribution chip, encapsulating the first data stream according to a terrestrial communication protocol, and encapsulating the second data stream according to a satellite communication protocol; detecting the signal parameters of 4G / 5G signals at a preset fixed period, and activating the satellite communication module and transmitting the second data stream when the signal parameters are detected to be lower than a preset threshold for N consecutive detection periods; and putting the satellite communication module into hibernation when the signal parameters are detected to be higher than the preset threshold; the ground control platform receiving data from the terrestrial link and the satellite link, parsing the data, and performing fusion processing with a unified spatiotemporal reference to output the identifier and flight parameters of each UAV. This invention constructs a dual-link redundant fusion transmission architecture between air and ground, enabling remote identification and trajectory monitoring of UAVs in all areas, all weather conditions, with high reliability and high security. It also expands to realize high-precision navigation and long-distance flight control of UAVs beyond visual line of sight, adapting to the diversified application needs of routine low-altitude management and control of UAVs in all areas and beyond visual line of sight operations. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described below with reference to the accompanying drawings, wherein: Figure 1 A flowchart of a method for remote transmission and identification of UAV RID provided in an embodiment of the present invention.

[0015] Figure 2 This is a schematic diagram of the modules of an unmanned aerial vehicle (UAV) system provided in an embodiment of the present invention. Detailed Implementation

[0016] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0017] This invention proposes an embodiment of a method for remote transmission and identification processing of unmanned aerial vehicle (UAV) RID (Remote Identification Number), specifically, as follows: Figure 1 As shown, it includes: Step 11: Configure a satellite communication module on the UAV's onboard terminal and connect it to the onboard RID module to establish a communication link between the UAV and the low-Earth orbit satellite constellation; Step 12: The raw data output by the RID module is copied into a first data stream and a second data stream by the data distribution chip. The first data stream is encapsulated according to the terrestrial communication protocol, and the second data stream is encapsulated according to the satellite communication protocol. Step 13: Detect the signal parameters of the 4G / 5G link at a preset fixed period. When the signal parameters are detected to be lower than a preset threshold for N consecutive detection periods, activate the satellite communication module and transmit the second data stream; when the signal parameters are detected to be higher than the preset threshold, put the satellite communication module into hibernation. Step 14: The ground control platform receives ground link data and satellite link data, parses the ground link data and satellite link data, and performs fusion processing with a unified spatiotemporal reference to output the identifier and flight parameters of each UAV.

[0018] In this embodiment, step 11 involves configuring a satellite communication module on the UAV's onboard terminal and connecting this satellite communication module to the onboard RID module to establish a communication link between the UAV and the low-Earth orbit (LEO) satellite constellation. The LEO satellite communication module and the LEO satellite network constellation work together to construct a satellite relay transmission channel, specifically adapted for beyond-line-of-sight (BLOS) flights in mountainous areas, forests, oceans, deserts, and areas without ground base stations. Through a complementary dual-link architecture, the technical limitations of traditional single-ground transmission modes in terms of coverage are addressed, enabling comprehensive monitoring of low-altitude airspace.

[0019] Preferably, the dual-link transmission mode operates in parallel with mutual backup throughout, and the broadcast mode is always in operation; the 4G / 5G link is the default priority link, and the satellite link is the backup link. When the 4G / 5G link fails, the satellite link is activated in a timely manner to ensure seamless monitoring of the drone.

[0020] Specifically, during routine drone flights, the onboard RID module continuously collects standardized flight parameters across all dimensions, including the drone's unique device ID, latitude and longitude coordinates, flight altitude, flight speed, heading, and attitude. All collected data undergoes lightweight encryption and solidification processing on the onboard device, and the entire data collection process is locked, prohibiting manual shutdown, tampering, or deletion, thus ensuring the uniqueness and authenticity of the original flight data from the source.

[0021] A low-Earth orbit (LEO) satellite communication transmission system compatible with the RID module is added to the airborne terminal, including an LEO satellite communication module, radio frequency unit, and antenna. The satellite communication module and the airborne RID module are connected via a data distribution chip. This hardware configuration does not require modification to the original airborne RID core hardware and operating logic of the UAV; the functional upgrade can be achieved simply by adding a lightweight chip and communication module.

[0022] In step 12, the original data output from the RID module is copied into a first data stream and a second data stream using a dedicated data distribution chip, forming two independent data streams from the same source. The first data stream is encapsulated according to the terrestrial communication protocol and adapted to the general message format of the existing broadcast / network mode, and transmitted directly according to the existing mode. The second data stream is encapsulated according to the satellite communication protocol and adapted to the transmission requirements of the low-orbit satellite network channel. The encapsulated message is then sent to the satellite communication module.

[0023] Preferably, the data replication and splitting is a lossless splitting, that is, no data compression, differential encoding, field pruning or downsampling processing is performed on the original RID data stream from the same source, and all original parameters of UAV encoding, position, speed and heading are completely preserved. Only satellite protocol standardized encapsulation is completed to achieve bit-level lossless transparent transmission.

[0024] Specifically, the dedicated data distribution chip reads the original RID data in real time, performs lossless copying and splitting of the same source data, generates two parallel data streams with completely identical content and independent transmission protocols, and performs differentiated protocol encapsulation processing: The first data stream strictly follows the existing RID general protocol, is encapsulated into a general message that is compatible with both broadcast and network modes, and is identified and parsed by the ground system according to the existing transmission mode, ensuring full compatibility with the existing low-altitude monitoring system.

[0025] The second data stream employs a satellite transparent channel transmission mechanism. It does not perform any data compression, differential encoding, field pruning, or downsampling on the original RID data stream from the same source, fully preserving all original parameters of the UAV, including its code, position, speed, and heading. It only performs dedicated protocol frame reconstruction and standardized encapsulation according to the low-Earth orbit satellite network narrowband transmission specifications, generating satellite-specific messages and sending them to the low-Earth orbit satellite communication module. This bit-level lossless transparent transmission mechanism ensures the integrity of the satellite transmission data, guaranteeing that the data reconstructed at the ground end is completely consistent with the original RID data.

[0026] In step 13, the system detects the signal parameters of the 4G / 5G signal at a preset fixed period. When the signal parameters are detected to be lower than the preset threshold for N consecutive detection periods (i.e., 4G / 5G signal loss, insufficient signal strength, or link interruption), the system automatically wakes up and activates the satellite communication module, switches to the low-orbit satellite network transmission mode, and continuously uploads satellite-specific RID messages. When the signal parameters are detected to be higher than the preset threshold (i.e., 4G / 5G signal is normal and link communication is stable), the system automatically puts the satellite communication module into hibernation and switches back to the 4G / 5G transmission mode.

[0027] Preferably, the preset fixed period is 100ms to 200ms. A link switching logic is triggered when the ground signal is abnormal for three or more consecutive detection cycles, avoiding frequent erroneous link switching caused by a single signal jitter.

[0028] Specifically, the system prioritizes terrestrial broadcasting and 4G / 5G by default, with broadcast mode operating online throughout. After the system is powered on, it continuously monitors 4G / 5G signal availability (including parameters such as signal strength, signal-to-noise ratio, and link availability) at 100ms to 200ms intervals.

[0029] When the system detects that the 4G / 5G signal parameters have reached the preset transmission threshold and the link communication is stable, the system automatically shuts down the satellite channel and the satellite module enters a low-power sleep state.

[0030] When the system detects 4G / 5G signal loss, insufficient signal strength, or link interruption for three consecutive detection cycles, it automatically wakes up the satellite module and switches to satellite transmission mode. Setting the judgment condition for three consecutive cycles can effectively avoid frequent false link switching caused by a single signal jitter, ensuring the stability and reliability of link switching.

[0031] After the satellite communication module is activated, the system updates the RID information every 1 second by default. To reduce satellite communication traffic costs, the system supports setting the communication service frequency based on the drone's maximum cruising speed. For high-speed cruising drones (such as fixed-wing drones with high cruising speeds), a higher information update frequency (short reporting cycle, such as 1 second) can be set to meet the real-time tracking requirements of safety supervision for high-speed moving targets. For low-speed flying or hovering drones (such as multi-rotor drones performing inspection tasks), a lower information update frequency can be set (the reporting cycle can be extended to 3-5 seconds), effectively saving satellite communication traffic while meeting basic regulatory requirements.

[0032] The specific value of the update frequency can be set comprehensively based on factors such as aircraft type, flight area safety level, and regulatory requirements, so as to achieve optimal control of communication costs while ensuring flight safety supervision needs.

[0033] Furthermore, once the 4G / 5G signal is restored, the system automatically switches back to 4G / 5G transmission mode, and the satellite channel re-enters a low-power sleep state. The link switching process does not interrupt RID data upload, achieving seamless switching and uninterrupted data transmission.

[0034] Step 14: With the satellite communication module activated, the airborne satellite communication module performs baseband signal modulation processing on the second data stream (satellite-specific RID message), converting the baseband digital signal into a radio frequency signal adapted for satellite transmission. After radio frequency amplification, the signal is transmitted to the low-Earth orbit satellite via an antenna. The low-Earth orbit satellite transmits the radio frequency signal to the ground satellite receiving system via relay. The ground satellite receiving system sequentially performs signal demodulation and data parsing processing on the received space radio frequency signal to restore the complete and original UAV RID data, thus completing the long-range beyond-line-of-sight RID data remote transmission and parsing.

[0035] Preferably, the radio frequency amplification includes primary power amplification of the radio frequency unit and secondary signal amplification of the satellite antenna, thereby improving the signal strength and transmission stability of long-distance satellite transmission through a two-stage amplification mechanism. After demodulation and parsing, the ground satellite receiving system outputs a complete UAV RID dataset, which can be directly used for UAV identification, flight location verification, and flight status monitoring.

[0036] Specifically, during satellite link transmission, the airborne satellite communication module modulates the satellite-specific RID message with baseband signals, converts the baseband digital signal into a radio frequency signal adapted for satellite transmission, and transmits it to the airborne radio frequency unit.

[0037] The airborne radio frequency unit performs primary power amplification on the modulated radio frequency signal before transmitting it to the satellite antenna; the satellite antenna performs secondary signal gain amplification on the received radio frequency signal, thereby improving the signal strength and transmission stability of long-distance satellite transmission through a two-stage amplification mechanism.

[0038] The amplified radio frequency signal is transmitted over a long distance via the antenna to a low-Earth orbit satellite constellation. The low-Earth orbit satellites then relay the radio frequency signal to the ground satellite receiving system. The ground end performs signal filtering, demodulation, and protocol restoration to obtain a complete original UAV RID dataset, which is then transmitted to the cloud management platform.

[0039] This embodiment also includes step 15, in which the cloud management platform receives broadcast, 4G / 5G, and satellite heterogeneous data in real time and parallel, and performs the following processing in sequence: Decryption and parsing: Decrypt the encrypted messages received from each link and parse the data according to their respective protocol formats; Abnormal data cleaning: Remove invalid data such as out-of-order data, data exceeding limits, data loss data, and data distortion data; Spatiotemporal reference registration: Registering and correcting deviations of multi-source data using a unified spatiotemporal reference; Normalization and merging: Merging and normalizing multiple heterogeneous but homogeneous data sources into a standardized identity and flight dataset unique to a single UAV (including device ID, latitude and longitude coordinates, flight altitude, flight speed, heading, and other flight parameters). Visualization and Intelligent Supervision: Real-time visualization of UAV flight information across the entire domain, construction of four-dimensional flight trajectories of UAVs based on fused and reliable data, and realization of unified data management, unified identity recognition, unified intelligent supervision and abnormal early warning output for UAVs across the entire airspace.

[0040] This embodiment can be extended to access RTK high-precision navigation interfaces and UAV flight control system interfaces. When the satellite communication module is active, the system receives navigation correction data sent from the ground via low-orbit satellites, and forwards it to the airborne navigation unit through the satellite communication module, providing the UAV with real-time high-precision positioning correction data, effectively reducing flight position deviation.

[0041] Meanwhile, the system can receive flight control commands sent from the ground via low-orbit satellites, and forward them to the airborne flight control unit through the satellite communication module, realizing beyond-line-of-sight remote flight control. This breaks through the traditional line-of-sight flight limitations of UAVs, supports UAVs in performing long-distance operations in areas without base station coverage, such as mountainous areas, oceans, and deserts, and greatly expands the application boundaries of the equipment.

[0042] like Figure 2 As shown, the UAV system in this embodiment includes a RID unit (Remote Identification Unit), a data splitting unit, a channel detection and switching unit, a star network module (core communication and data processing unit), an interface unit (peripheral adapter hub), a radio frequency unit, and an antenna unit.

[0043] The RID unit is the top-level identification input unit of the system, responsible for issuing unique device identification and permission verification commands, serving as the identity entry point for data interaction across the entire machine. Data is then routed to the data splitting unit for distribution processing.

[0044] The data splitting unit serves as the core data distribution hub, possessing multi-path data distribution capabilities: Upward output: Interacts with existing transmission modules, reuses the original airborne communication links, and achieves compatible data forwarding without modifying the original communication hardware of the entire machine; Downward output: Send the verified data to the StarNet module and start the satellite communication link.

[0045] The channel detection and switching unit is used to detect 4G / 5G signals. When the 4G / 5G communication signal is interrupted or unavailable, the system adaptively switches to the star network transmission mode. When the 4G / 5G communication signal is restored to availability, the system switches the signal back to the network working mode.

[0046] The StarNet module (core communication and data processing unit) is used to receive service data sent by the split unit and complete the transmission and reception of satellite signals between Earth and space through the antenna system; it outputs standardized interface signals to the interface unit to realize the interoperability of positioning and flight control data.

[0047] The interface unit (peripheral adapter hub) integrates BeiDou positioning and high-precision navigation modules to achieve navigation and monitoring functions. It can also interconnect with the flight control unit of UAVs / aircraft, providing remote flight control capabilities for UAVs.

[0048] The radio frequency unit is used to amplify the signal and send it to the antenna unit.

[0049] The antenna unit is located in the radio frequency front end of the StarNet module and is responsible for transmitting and receiving satellite radio frequency signals.
