Description

Technical Field

[0001] The present invention relates to the technical field of low-altitude traffic, and particularly to a low-altitude RSU device, a low-altitude RSU system and a control method based on the SparkLink technology. Background Art

[0003] With the rapid rise of the low-altitude economy, low-altitude unmanned aerial vehicles (UAVs) are playing an increasingly important role in multiple fields, such as logistics distribution, urban inspection, emergency rescue, etc. With their flexible, efficient and fast characteristics, UAVs can complete many tasks that cannot be easily solved by traditional methods in the urban environment. For example, UAVs can perform express delivery in cities with high-rise buildings or execute emergency rescue tasks in areas with inconvenient transportation. However, in practical applications, this emerging technology also faces a series of technical challenges, especially in communication.

[0004] Firstly, in the urban environment, traditional communication technologies are difficult to meet the communication requirements of low-altitude UAVs for stability, low latency and high reliability. The high-rise buildings in the city are densely packed, and the complex structure between buildings easily causes signal occlusion and interference, making the communication signal between the UAV and the ground control center unstable. This instability may cause high latency and even data loss, thus seriously affecting the flight control and mission execution of the UAV. For example, when the UAV flies through between high-rise buildings or in enclosed areas such as tunnels, the communication signal may be completely interrupted, resulting in the UAV being unable to receive instructions from the ground control center or unable to transmit flight data in real time, affecting the safety and accuracy of the operation. Traditional wireless communication technologies, such as Wi-Fi, LTE, etc., often cannot provide a sufficiently stable signal in the complex urban environment, especially in areas with low flight altitude and high-rise buildings in the city, and this challenge is even more prominent.

[0005] Secondly, there are still many gaps and technical barriers in the application of current low-altitude UAVs in the field of traffic management. The coordinated work between ground traffic management and low-altitude flight has not been effectively realized, especially the integration degree of UAVs with ground traffic infrastructure such as roadside units, traffic lights, traffic monitoring cameras, etc. is relatively low. When performing tasks, low-altitude UAVs often need to cooperate closely with ground traffic. For example, in an emergency, the UAV needs to coordinate with ground vehicles to avoid collisions, or in urban inspection, it needs to share real-time road conditions information with the ground traffic management system. However, due to the incomplete integration of the technologies and information systems of ground traffic management and low-altitude UAVs, seamless docking and information sharing between ground and air traffic cannot be achieved, which makes traffic management more complex and may even lead to conflicts and chaos between air and ground traffic.

[0006] Therefore, it is necessary to design a new device to realize the use of an RSU with SparkLink technology as a bridge between low-altitude vehicles, combine the RSU with low-altitude vehicles, achieve traffic coordination of unmanned aerial vehicle groups, and support high-network communication, collaborative operation, and efficient task execution in complex environments.

[0029] The applications of low-altitude unmanned aerial vehicles (UAVs) are increasing in fields such as logistics distribution, urban inspection, and emergency rescue. However, in practical applications, they face challenges in communication technology and traffic management. The dense high-rise buildings and complex structures in urban environments often lead to signal interference and instability, affecting the communication between UAVs and ground control centers. In terms of traffic management, the integration of UAVs with ground traffic facilities is relatively low, lacking effective collaborative work, resulting in difficulties in seamless docking between air and ground traffic, thus increasing the complexity and potential risks of operations.

[0030] Therefore, the embodiments of the present invention provide a low-altitude RSU device 10, a low-altitude RSU system, and a control method based on SparkLink technology, which realize using an RSU with SparkLink technology as a bridge between the low-altitude vehicle 12, combining the RSU with the low-altitude vehicle 12 to achieve traffic coordination of UAV groups, and supporting high-network communication, collaborative operation, and efficient task execution in complex environments.

[0031] The low-altitude RSU device uses an RSU unit 11 with SparkLink technology to connect with a low-altitude vehicle 12 such as a UAV, constructing an efficient communication bridge. The SparkLink module 111 exchanges data with the vehicle through the low-altitude RSU device, realizing real-time sharing of the flight status data of the low-altitude vehicle 12, and being able to establish an efficient data communication channel between multiple low-altitude vehicles 12. The device is also equipped with positioning, obstacle avoidance, and communication modules to ensure efficient collaborative operation in complex environments. At the same time, through the broadcast and communication functions of the SparkLink module 111, the RSU device supports the collaborative execution of tasks between low-altitude vehicles 12, and provides support for UAV group traffic coordination and task execution, enhancing the network communication ability and task processing ability of the system.

[0032] To better understand the above technical solutions, the above technical solutions will be described in detail below in combination with the accompanying drawings of the specification and specific implementation manners.

[0033] Please refer to Figure 2 , a low-altitude RSU device 10 based on SparkLink technology, including an RSU unit 11 and a low-altitude vehicle 12, the RSU unit 11 is connected to the low-altitude vehicle 12; the RSU unit 11 includes a SparkLink module 111.

[0034] In this embodiment, the RSU unit 11 is the core communication module of the system, with SparkLink communication technology. The SparkLink module 111 is built into the RSU unit 11 and supports multiple communication functions to ensure high-speed and low-latency communication with other UAVs and ground RSUs in the low-altitude environment.

[0035] The low-altitude vehicle 12 generally refers to a drone or other aircraft carrying the RSU unit 11. The RSU unit 11 on the vehicle can be powered and communicate through specific hardware interfaces to ensure stable supply of data and power.

[0036] Through the USB or Ethernet interface, the RSU unit 11 can perform real-time data interaction with the low-altitude vehicle 12, transmit flight status data, sensor information, etc., and at the same time power the RSU unit 11.

[0037] In this embodiment, the above-mentioned RSU unit 11 can be connected to the low-altitude vehicle 11 through a connection structure. Specifically, the above-mentioned connection structure can adopt a bracket or a gimbal link. When using a bracket, the RSU unit 11 is docked with the screw holes of the low-altitude vehicle 12 through the bracket to ensure firm fixation and can adapt to different models of low-altitude vehicles 12; when using a gimbal link, the gimbal link adopts a carbon fiber composite material bracket, which has high-strength connection and excellent seismic resistance. The carbon fiber composite material has the advantages of light weight, high strength, corrosion resistance, etc., which can effectively reduce the weight of the connection structure and at the same time ensure the stability and reliability during high-speed movement. The two ends of the gimbal link are bonded by epoxy glue. This bonding method ensures the strength and stability of the connection structure, can resist external vibration and impact, and avoid unnecessary displacement or loosening during flight, further improving the stability of the entire system.

[0038] The design of the connection structure not only meets the mechanical connection requirements between the low-altitude vehicle 12 and the RSU unit 11, but also optimizes the stability of the data transmission channel. Due to the use of carbon fiber composite materials, the system can maintain light weight while ensuring that the gimbal unit can work stably under different flight conditions, avoiding the decline of data transmission quality or inaccurate positioning caused by vibration or external interference.

[0039] By combining the low-altitude vehicle 12, the RSU unit 11 and the high-strength connection structure, the system effectively solves the problems of inaccurate positioning and unstable data transmission of low-altitude flying vehicles in complex environments. Especially, the gimbal link adopts carbon fiber composite materials, which provides light weight while ensuring strength and seismic resistance, enabling the entire low-altitude RSU system to work stably and efficiently during flight, ensuring the precise positioning and efficient management of the low-altitude vehicle 12.

[0040] In one embodiment, as Figure 3 shown, the above-mentioned RSU unit 11 can also be connected to the low-altitude vehicle 12 through other communication bus structures. The above-mentioned communication bus structure includes a drag chain guide rail, and the drag chain guide rail is cascaded and connected in a way of tank chain buckles; the two ends of the drag chain guide rail are respectively connected to the low-altitude vehicle 12 and the RSU unit 11 through joints.

[0041] In this embodiment, the drag chain guide rail is made of high-performance engineering plastic materials (such as Suzhou Weibon T31 material), which have high impact resistance and fatigue resistance characteristics. These materials ensure the durability and stability of the drag chain guide rail during long-term use. Even in low-temperature and extreme environments, it can still maintain good toughness and structural strength. Compared with traditional metal hinges, engineering plastics are not only lighter in weight but also can effectively reduce the impact of external vibrations and shocks on the system.

[0042] The design of the drag chain guide rail utilizes materials with high impact resistance and high fatigue resistance to ensure that when it bears external vibrations and shocks during operation, it can still stably transmit power and data. The advantages of this material are reflected in the lightness of the structure and long-term use stability. Especially in the case of low-empty load carriers 12 flying at high speed and complex environments, it can provide more reliable support.

[0043] The connection method of the drag chain guide rail adopts the cascading connection of the tank chain buckle method. This connection method enables the drag chain guide rail to be flexibly connected in a buckle form, facilitating installation and maintenance. The tank chain buckle connection provides very high reliability and stability, ensuring that each part will not fall off or become loose under high-frequency motion and external environmental changes.

[0044] This connection method not only ensures the continuity and stability of the guide rail but also allows the system to adjust the length of the drag chain according to needs to adapt to different working scenarios.

[0045] To ensure the reliable connection between the drag chain guide rail and the low-empty load carrier 12 and the RSU unit 11 in a harsh environment, corrosion-resistant and waterproof joints are used at both ends. These joints provide effective protection for the power line and high-speed data line, preventing water vapor, dust, or other external factors from damaging the communication line.

[0046] The joints have excellent corrosion resistance and waterproof performance, which can ensure good electrical contact even in complex environments such as humidity and salt spray, preventing electrical failures caused by joint corrosion or water stains.

[0047] Connecting the low-empty load carrier 12 and the RSU unit 11: The joints at both ends are respectively connected to the low-empty load carrier 12 and the RSU unit 11. Through specially designed joints and interfaces, the stable transmission of power and data lines is ensured without being affected by the external environment.

[0048] The inside of the drag chain guide rail contains a power line and a high-speed data communication line (such as gigabit and hundred-megabit network cables, etc.) for providing power support and data transmission for the low-empty load carrier 12 and the RSU unit 11. The high-speed data line ensures real-time data exchange between the low-empty load carrier 12 and the RSU unit 11, guaranteeing the rapid response and precise control of the system. The power line provides a stable power source to ensure the normal operation of the system.

[0049] Adopt a high-speed network cable (such as a gigabit or hundred-megabit network cable) to provide a fast and stable data transmission channel, ensuring that the real-time communication between the low-empty vehicle 12 and the RSU unit 11 is not interrupted.

[0050] In this embodiment, the communication bus structure realizes reliable and efficient power and data transmission between the low-empty vehicle 12 and the RSU unit 11 through a drag chain guide rail connected in series by using a tank chain buckle method, combined with high-strength engineering plastic materials and corrosion-resistant and waterproof connectors. The drag chain guide rail provides a stable and durable connection system, which can ensure the efficient operation of the system in a complex flight environment and avoid system failures caused by interference from the external environment to the power line and data communication line.

[0051] In one embodiment, please refer to Figure 1 , the above-mentioned SparkLink module 111 includes a SparkLink chip, a first switching element, a power amplifier, a first filter, a second switching element, a second filter, a noise amplifier, a third filter, and a SparkLink antenna. The SparkLink chip is connected to the first switching element, and the first switching element is connected to the power amplifier; the power amplifier is connected to the first filter; the first filter is connected to the second switching element; the second switching element is respectively connected to the second filter and the SparkLink antenna; the second filter is connected to the noise amplifier; the noise amplifier is connected to the third filter; the third filter is connected to the first switching element.

[0052] In this embodiment, one of the core components of the SparkLink module 111 is the signal processing unit of the entire system. It is responsible for data transmission and processing. The SparkLink chip is connected to the first switching element through its interface to switch the signal path in different communication states.

[0053] The function of the first switching element is to control the signal path switching. When the SparkLink chip sends a signal, the first switching element transmits the signal through the power amplifier; when receiving a signal, it transmits the received signal to the SparkLink chip for processing.

[0054] The power amplifier PA is used to enhance the power of the signal, amplify the signal sent by the SparkLink chip to a sufficient intensity to ensure that the signal can cover a larger range. The power amplifier is connected to the first filter to ensure signal quality and reduce signal spurs.

[0055] The first filter BF1 is used to filter out unwanted spurious signals, ensure that the signal after power amplification is purer, and reduce interference. It receives the signal from the power amplifier and transmits the processed signal to the second switching element.

[0056] The function of the second switching element is to further switch the signal path to ensure smooth signal transmission. It transmits the signals of the first filter to the second filter or the StarFlash antenna respectively to adapt to different working modes.

[0057] The main function of the second filter BF2 is to further filter out unnecessary signals and reduce interference. It is connected to the second switching element and filters out signals in other frequency bands to ensure the best signal quality received by the StarFlash module 111.

[0058] The noise amplifier LNA is used to enhance the received weak signals, especially the signals from remote RSUs or other UAVs. It helps to increase the intensity of the received signals and ensure accurate data transmission.

[0059] The third filter BF3 is the final signal filtering component, which is used to further remove noise and spurious signals. It is connected to the noise amplifier to ensure signal purity so as to transmit the received signals to the first switching element.

[0060] The StarFlash antenna is the output and receiving end of the entire communication system. It is responsible for actual wireless communication with other devices (such as UAVs, ground RSUs, etc.). Through the StarFlash antenna, the RSU module can communicate with surrounding devices with low latency and high rate.

[0061] When the StarFlash chip needs to send a signal, the first switching element will switch the signal path to the power amplifier. After power amplification, the signal is filtered by the first filter and then switched to the StarFlash antenna through the second switching element, thus realizing signal broadcasting.

[0062] When receiving signals from other devices, the signals are first received by the StarFlash antenna. The received signals are filtered by the third filter, amplified by the noise amplifier, further processed by the second filter, and finally transmitted to the StarFlash chip through the second switching element for processing and decoding.

[0063] The StarFlash module 111 realizes the communication function with low latency and high rate through the cooperation of the above components, supporting efficient data transmission and collaborative operations between UAVs and ground RSUs. The design of each module aims to reduce signal interference, improve communication quality, and ensure stable operation in complex environments.

[0064] In one embodiment, please refer to Figure 1 , the above-mentioned RSU unit 11 further includes a processor, and the processor is connected to the StarFlash module 111.

[0065] In this embodiment, the RSU unit 11 includes a high-performance processor. This processor is the core of the entire system and is responsible for processing the communication data, flight status information between the drone and the RSU unit 11, as well as the sensing data from other modules. The SparkLink module 111 is connected to the processor and undertakes the high-speed and low-latency communication tasks with other drones, ground RSUs, or control platforms. The working principle of the SparkLink module 111 is to exchange data through high-frequency signals, ensuring that the drone can work in real-time coordination with other devices and avoiding flight interference.

[0066] In one embodiment, please refer to Figure 1 , the above-mentioned RSU unit 11 further includes a communication interface module, and the communication interface module is respectively connected to the processor and the low-altitude vehicle 12.

[0067] In this embodiment, the communication interface module of the RSU unit 11 is connected to the low-altitude vehicle 12 (drone) through a USB or Ethernet interface. These interfaces can effectively support data transmission and have high stability and scalability at the same time. The selection of the USB or Ethernet interface enables the RSU unit 11 to communicate seamlessly with other devices in the drone system. The processor receives the flight status data of the drone, such as position, speed, attitude, etc. through these interfaces, and transfers this information to other systems for subsequent processing or coordination.

[0068] In one embodiment, please refer to Figure 1 , the above-mentioned communication interface module includes a USB interface and / or an Ethernet interface.

[0069] In one embodiment, please refer to Figure 1 , the above-mentioned RSU unit 11 further includes a positioning module, an obstacle avoidance module, and a communication module, and the positioning module, the obstacle avoidance module, and the communication module are respectively connected to the processor.

[0070] In one embodiment, please refer to Figure 1 , the above-mentioned positioning module includes a GNSS module, and the obstacle avoidance module includes a radar obstacle avoidance module.

[0071] In this embodiment, the positioning module mainly includes a GNSS module for providing accurate position information. The GNSS module communicates with satellites in real-time to ensure that the drone can obtain high-precision positioning data. This is crucial for navigation, mission execution, and obstacle avoidance during low-altitude flight.

[0072] The obstacle avoidance module is mainly composed of a radar obstacle avoidance module, which can monitor the surrounding environment in real-time, identify obstacles, and calculate the best path to avoid obstacles. This helps to ensure that the drone can fly safely in a complex environment and avoid collisions or interference.

[0073] In addition to the SparkLink module 111, the RSU unit 11 also integrates other communication modules, such as 4G, 5G, etc. These modules not only support data exchange with the internal system of the drone, but also enable data transmission between other drones and ground RSUs, thus realizing complex collaborative tasks and dynamic network construction.

[0074] The 4G / 5G communication module supports mobile Internet communication to ensure data transmission between the low-altitude vehicle 12 and the ground station or other devices. It is also backward compatible with 3G / 2G and enables real-time information transmission through the communication module.

[0075] In the working process of the RSU unit 11, first, the processor actively establishes a communication channel with the drone system through the USB or Ethernet interface to read the flight status data. At the same time, the SparkLink module 111 broadcasts its connection information and scans for other nearby SparkLink devices (including ground RSUs or other drones). Once two RSU units 11 successfully establish a connection, they exchange flight data and sensor information with each other. After being processed by the processor, this information is transmitted to the drone for corresponding flight operations.

[0076] Meanwhile, the positioning module provides real-time position information for the drone to ensure flight accuracy; the obstacle avoidance module senses surrounding obstacles through radar and provides real-time obstacle avoidance instructions. The communication module ensures efficient and reliable data transmission between all modules, guaranteeing the overall cooperation of the system.

[0077] Through the above design, the RSU unit 11 can achieve efficient cooperation between the drone and the ground system, not only ensuring the safety and reliability of low-altitude flight, but also supporting multi-directional collaborative operations of the drone through SparkLink technology in complex environments.

[0078] In this embodiment, the communication module includes a 5G communication module, and the models of this 5G communication module include but are not limited to SRM825, SRM817; the models of the GNSS module include but are not limited to M8Q, F9P; the models of the SparkLink chip include but are not limited to TR5510, DX-T600.

[0079] The above-mentioned low-altitude RSU device 10 based on SparkLink technology integrates a SparkLink module 111 through an RSU unit 11, establishes a connection with a low-altitude vehicle 12 such as a drone, acts as a bridge between the two, and realizes efficient communication and collaborative operations; the SparkLink technology provides the RSU unit 11 with high-speed and low-latency communication capabilities, supports high-network communication and real-time data exchange among drone groups in complex environments, thus ensuring safety, stability, and efficient task execution during low-altitude flight, and promoting multi-faceted collaborative operations. Overall, it realizes using the RSU with SparkLink technology as a bridge between the low-altitude vehicle 12, combines the RSU and the low-altitude vehicle 12, realizes traffic collaboration among drone groups, supports high-network communication, collaborative operations, and efficient task execution in complex environments.

[0080] In one embodiment, please refer to Figure 2 , a low-altitude RSU system is further provided, including a ground RSU device 20 and several of the above-mentioned low-altitude RSU devices 10 based on SparkLink technology; several low-altitude RSU devices 10 based on SparkLink technology are communicatively connected through the SparkLink module 111; several low-altitude RSU devices 10 based on SparkLink technology are communicatively connected with the ground RSU.

[0081] In one embodiment, please refer to Figure 2 , the ground RSU includes a SparkLink module 111, and several low-altitude RSU devices 10 based on SparkLink technology are communicatively connected with the ground RSU through the SparkLink module 111.

[0082] In one embodiment, the design of the low-altitude RSU system combines the ground RSU device 20 and multiple low-altitude RSU devices, and all these devices are communicatively connected based on SparkLink technology. The core function of this system is to realize effective collaboration between drones and the ground traffic system and real-time communication among drones, enhancing the intelligence and efficiency of low-altitude flight.

[0083] The low-altitude RSU system includes a ground RSU device 20 and several low-altitude RSU devices 10 based on SparkLink technology. The ground RSU device 20 is located on the ground, responsible for connecting and exchanging data with low-altitude RSU devices and other systems, and providing functions of centralized management and monitoring of information. The low-altitude RSU device is installed on a low-altitude drone and serves as a communication hub for the drone, performing real-time data exchange and information transmission with other drones and the ground RSU device 20.

[0084] Low-altitude RSU devices are communicatively connected through the SparkLink module 111. These low-altitude RSU devices are based on SparkLink technology and have the advantages of low latency, high speed, and concurrent connection of multiple devices. Each low-altitude RSU device can be interconnected with other low-altitude RSU devices through the SparkLink module 111 to form a dynamic network environment. Through this network, drones can achieve network communication and collaborative operations, ensuring real-time data transmission and mutual cooperation during flight, and greatly improving the working efficiency and collaborative ability of the drone system.

[0085] In this embodiment, the ground RSU device 20 is equipped with the SparkLink module 111, and it is communicatively connected with the low-altitude RSU device through the SparkLink module 111. When a low-altitude RSU device enters the communication range of the ground RSU, the ground RSU will automatically establish a communication channel with the low-altitude RSU device, and data exchange and information transmission are carried out between the two through the SparkLink module 111. This connection can not only support real-time data interaction between the ground and low-altitude aircraft, but also ensure that the ground system can timely receive information such as the flight status, sensor data, and position positioning of the drone, so as to realize effective monitoring and management of low-altitude drones.

[0086] The low-altitude RSU system supports efficient communication between multiple low-altitude RSU devices and the ground RSU, and can meet the networking requirements of multiple drones. During implementation, multiple drones can exchange data through their respective low-altitude RSU devices and perform tasks under the coordination of the ground RSU. Due to the low latency and high reliability of SparkLink technology, the system can operate stably in complex environments, ensuring that drones can respond quickly and avoid flight obstacles when performing tasks.

[0087] Due to the low latency and high data transmission rate characteristics of the SparkLink module 111, the low-altitude RSU system can dynamically construct an efficient communication network. During flight, the drone establishes a connection with surrounding drones or the ground RSU device 20 through the SparkLink module 111 to share flight data and environmental information in real time. In addition, the communication between the ground RSU and the low-altitude RSU device can also ensure the stability and reliability of the system in large-scale tasks or complex environments.

[0088] The low-altitude RSU system of this embodiment can achieve efficient coordination between low-altitude aircraft and the ground traffic system, as well as network communication and collaborative operations between drones through the low-altitude RSU device 10 and the ground RSU device 20 based on SparkLink technology. Through this system structure, the ground RSU can communicate with multiple low-altitude RSU devices in real time to ensure the timely transmission of information such as the flight status, task execution, and obstacle avoidance of drones, so as to realize the efficient management and task completion of drones.

[0089] The working process of the entire system is as follows: The RSU unit 11 of the low-altitude RSU device is connected to the low-altitude vehicle 12 through a USB or Ethernet interface. When the RSU unit 11 is powered on, it will actively establish a data communication channel with the low-altitude vehicle 12 through a specific communication protocol and request to read the flight status and relevant data of the low-altitude vehicle 12. The low-altitude vehicle 12 then transmits its flight status, sensor data, etc. in real time to the processor of the RSU unit 11 through the USB or Ethernet interface.

[0090] After the RSU unit 11 is powered on, the processor will automatically configure the XingShan module 111 to enter the working state, broadcast its own information, and at the same time try to discover the XingShan modules 111 of other RSU devices around. When two XingShan modules 111 successfully discover each other, a data connection channel will be established. After the connection is successful, the RSU unit 11 will package and transmit the flight status information (such as positioning location, attitude information, speed information, etc.) of the low-altitude vehicle 12 to other RSU devices. In addition, the RSU unit 11 will also receive the flight data of the low-altitude vehicle 12 or ground notification information transmitted by other RSU devices, and send the processed information to the low-altitude vehicle 12.

[0091] This system can realize network communication and cooperative operation among multiple unmanned aerial vehicles, and effectively coordinate the interaction between the low-altitude flight of unmanned aerial vehicles and the ground traffic system. This technology not only improves the cooperation efficiency of the unmanned aerial vehicle system, but also strengthens the intelligent management ability of unmanned aerial vehicles in low-altitude flight, with significant technological innovation and application prospects.

[0092] The above-mentioned low-altitude RSU system, by adopting the RSU unit 11 with XingShan technology, as a bridge between the low-altitude vehicle 12 (such as an unmanned aerial vehicle) and the ground system, has successfully realized efficient communication and cooperative operation among unmanned aerial vehicle groups. The network connection established by this system using XingShan technology supports high-speed network communication in complex environments, ensuring seamless data transmission and cooperative task execution among multiple unmanned aerial vehicles. The combination of the RSU unit 11 and the low-altitude vehicle 12 enables the unmanned aerial vehicle to effectively cooperate with the ground traffic system during flight, realizing intelligent management and precise task execution.

[0093] In one embodiment, please refer to Figure 4 , there is also provided a control method for the above-mentioned low-altitude RSU system, including steps S110 to S150.

[0094] S110. When the low-altitude RSU device is powered on, the corresponding XingShan module 111 enters the working mode; S120. The XingShan module 111 starts to broadcast its own relevant information for discovering other XingShan modules 111; S130. When two XingShan modules 111 discover each other, establish a data connection channel between the two XingShan modules 111; S140. The low-altitude RSU device packs the flight state data of the low-altitude vehicle 12 and sends it to other StarFlash modules 111. Meanwhile, the RSU unit 11 of the low-altitude RSU device receives the flight information sent by other StarFlash modules 111 or the notification information from the ground station; S150. The RSU unit 11 of the low-altitude RSU device processes the received information and then sends it to the low-altitude vehicle 12.
