Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a relay remote transmission control system and method for UAV meteorological data. Background Technology

[0002] During the remote deployment of drones, meteorological data is crucial for the drone's flight status.

[0003] Currently, the placement of weather sensors around drone hangars has several drawbacks. Firstly, installing sensors on the hangar's hinged doors occupies structural space and increases the risk of collisions during drone takeoff and landing. Secondly, installing sensors on poles next to the hangar requires additional space for the poles and designing sensor mounting positions on them, significantly increasing design and deployment complexity. Furthermore, drone hangars are typically located in low-lying, flat areas, while drones actually fly at higher altitudes. Meteorological data monitored at lower elevations differs from the actual weather conditions in the drone's flight area. Moreover, meteorological monitoring in low-altitude flat areas is susceptible to obstructions and human interference, leading to reduced data accuracy and failing to meet the high-precision meteorological data requirements of drones, thus affecting the precise control of drone flight.

[0004] It is evident that the existing drone weather sensors are poorly positioned in the drone hangar, posing a collision risk and causing significant discrepancies between the monitoring data and the weather conditions in the drone's flight area, thus affecting flight safety and data accuracy. Summary of the Invention

[0005] In view of this, the present invention provides a relay remote transmission control system and method for UAV meteorological data to solve the problems of unreasonable layout of existing UAV meteorological sensors in UAV hangars, collision risks, and large differences between the monitored data and the meteorological conditions in the UAV flight area, which affect flight safety and data accuracy.

[0020] The ground-based repeater is wirelessly connected to the hangar-based repeater to transmit the meteorological data to the hangar-based repeater via wireless signals.

[0021] The hangar-end repeater is connected to the hangar host computer via a serial port interface to transmit the meteorological data received from the ground-end repeater to the hangar host computer.

[0022] The host computer in the hangar is connected to the management platform via an Ethernet interface to transmit the meteorological data to the management platform and receive control commands sent by the management platform.

[0023] In one alternative implementation, the drone further includes a flight controller;

[0024] The hangar-end repeater is also wirelessly connected to the airborne end repeater to send the control commands to the airborne end repeater;

[0025] The airborne repeater is also connected to the flight controller via a serial interface to send the control commands to the flight controller and control the flight status of the UAV.

[0026] Secondly, the present invention provides a method for relaying and controlling UAV meteorological data, the method being applied in a management platform of a UAV meteorological data relay and control system, the method comprising:

[0028] Based on the meteorological data, generate drone control commands;

[0029] The control commands are sent to the UAV via a wireless link consisting of a hangar-end repeater and an airborne repeater to control the flight status of the UAV.

[0030] Thirdly, the present invention provides a relay remote transmission control device for UAV meteorological data, the device being applied in a management platform of a UAV meteorological data relay remote transmission control system, the device comprising:

[0031] The meteorological data acquisition module is used to acquire meteorological data collected by meteorological station sensors through a wireless link consisting of a hangar-end repeater and a ground-end repeater.

[0032] The UAV control command generation module is used to generate UAV control commands based on the meteorological data;

[0036] In a sixth aspect, the present invention provides a computer program product, including computer instructions, which are used to cause a computer to execute a method for relaying and controlling UAV meteorological data according to the first aspect or any corresponding embodiment described above.

[0037] The technical solution provided by this invention may include the following beneficial effects:

[0038] 1. Through wireless signal communication and data transmission via three sets of repeaters (ground-end repeater, hangar-end repeater, and airborne repeater), it is not limited by 4G / 5G networks. Even in remote, high-altitude, border, and uninhabited areas where there is no network signal, it can ensure the smooth and accurate transmission of meteorological data signals, thereby ensuring that the flight status of the UAV can be accurately controlled based on real-time meteorological data.

[0039] 2. By setting the meteorological sensor on the ground relay system deployed above the preset altitude, there is no need to install the meteorological sensor on or near the drone hangar. This avoids the collision risk that the sensor may cause on the drone hangar, as well as the extra space and complex design required for pole installation. It simplifies the structural design, makes installation and deployment more convenient, and reduces human interference to the sensor.

[0040] 3. The ground relay system (including wind and solar power platforms and meteorological station sensors) is deployed in high-altitude areas above the altitude threshold. These areas have fewer obstructions and the meteorological conditions are closer to the actual flight environment of UAVs. Therefore, the collected meteorological data such as wind, rain, snow, and temperature are more accurate, providing a more reliable basis for the flight control of UAVs and helping to improve the safety and reliability of UAV flights.

[0041] 4. Multiple ground repeaters and wind and solar power platforms can be easily deployed in multiple areas. Based on the area where the UAV flies, the meteorological information of that area can be accurately determined, thereby achieving precise positioning and flight control of the UAV and enhancing the system's adaptability to different flight environments.

[0042] 5. The system can flexibly add or remove data collected by different meteorological sensors according to actual conditions, adjust the constraints of meteorological data for different regions, and flexibly adjust the control algorithm according to the UAV's flight status to achieve better control of the UAV's flight status, giving the system good flexibility and scalability.

[0050] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] This embodiment provides a relay control system for UAV meteorological data, which can be used to execute the following UAV meteorological data relay control method. Figure 1 This is a schematic diagram of a remote transmission control system for UAV meteorological data according to an embodiment of the present invention, as shown below. Figure 1 As shown, the system includes:

[0052] The remote equipment includes a ground-based relay system deployed at a preset altitude and a drone equipped with a carrier-based relay; the ground-based relay system includes a wind and solar power platform and a ground-based relay; the wind and solar power platform is equipped with a weather station sensor for collecting meteorological data and transmitting it to the ground-based relay;

[0053] Local equipment includes a drone hangar and management platform; the drone hangar is equipped with a hangar-side repeater.

[0054] The management platform is used to receive meteorological data through a wireless link formed by the hangar-end repeater and the ground-end repeater, generate UAV control commands based on the meteorological data, and send the control commands to the UAV through the wireless link formed by the hangar-end repeater and the airborne repeater to control the flight status of the UAV.

[0055] Furthermore, such as Figure 1As shown, the hardware communication link of this system mainly includes remote equipment, local equipment, and the transmission of control and meteorological data between them. The remote equipment includes a ground relay system and the UAV. The ground relay system includes a wind-solar power supply platform and ground repeaters. The local equipment is mainly divided into a UAV hangar and a management platform. The three repeaters—the ground repeater, the hangar repeater, and the airborne repeater—all transmit data via 2.4G or 1.4G frequency band wireless signals. The meteorological data algorithm is integrated into the local management platform. After receiving different meteorological data collected by the meteorological station sensors, the platform analyzes and processes the meteorological data and outputs the control status of the UAV based on the analysis results.

[0056] The remote equipment is deployed in high-altitude areas (above a preset altitude, such as 2000m) for meteorological data collection and initial transmission. The ground-based relay system within the remote equipment consists of a wind-solar power supply platform and ground-based repeaters. The wind-solar power supply platform can achieve off-grid power supply through components such as wind turbines, photovoltaic panels, and batteries. Meteorological station sensors (including rain and snow sensors, wind speed and direction sensors, and temperature and humidity sensors) are integrated into this platform to collect real-time meteorological data of the flight area and transmit it to the ground-based repeaters via a serial interface. The UAV is equipped with an onboard repeater, connected to the flight controller via a serial interface, for receiving control commands and performing flight status adjustments.

[0057] The local equipment includes a drone hangar and a management center for data processing and command generation. The drone hangar integrates a hangar-side repeater and a hangar-side host computer. The hangar-side repeater communicates with the ground-side repeater via 2.4G / 1.4G wireless signals, while the hangar-side host computer interacts with the management platform via Ethernet. The management platform is equipped with a meteorological data algorithm scheme to receive meteorological data, generate control commands, and distribute them to the drones via wireless links. In this embodiment, the ground-side repeater and the hangar-side repeater transmit data wirelessly, and the hangar-side repeater also transmits data wirelessly with the airborne repeater.

[0058] In one alternative implementation, the wind and solar power supply platform includes a wind turbine, a wind turbine controller, a photovoltaic panel, a photovoltaic controller, and a battery.

[0059] The wind turbine charges the battery through its controller; the photovoltaic panel charges the battery through its controller.

[0060] The battery is electrically connected to the ground terminal repeater and is used to supply power to the ground terminal repeater.

[0061] Furthermore, due to the limitations of wireless signal transmission distance during remote deployment of drones, ground repeaters are generally required within a certain distance to serve as signal relay stations for drone positioning and data transmission. These ground repeaters are typically located at high altitudes, such as mountaintops. Mountaintops generally lack access to mains power; therefore, the power supply for the relay equipment used for data reception can be provided by a wind-solar hybrid power supply system, creating a complete deployment solution. A wind-solar hybrid power supply system utilizes wind and solar energy to supplement each other in supplying power to the load. It mainly includes components such as wind turbines, wind turbine controllers, photovoltaic panels, photovoltaic controllers, and batteries. The wind turbines convert wind energy into electrical energy, and the photovoltaic panels convert solar energy into electrical energy, which then charges the batteries, ultimately powering the load. In this embodiment, the wind-solar hybrid power supply system can be a wind-solar power supply platform. This platform is used for energy security in off-grid environments and includes wind turbines, wind turbine controllers, photovoltaic panels, photovoltaic controllers, and batteries. The wind turbine converts wind energy into electrical energy through the wind turbine controller, and the photovoltaic panel converts solar energy into electrical energy through the photovoltaic controller. Both of them charge the battery. The battery is electrically connected to the ground-side repeater through a DC-DC voltage regulator circuit to output a stable voltage (such as 5V / 12V) to avoid voltage fluctuations damaging the equipment.

[0062] In one alternative implementation, the weather station sensor includes at least one of a rain / snow sensor, a wind speed and direction sensor, and a temperature and humidity sensor.

[0063] The rain and snow sensor is used to collect rainfall and snowfall data in the flight area of ​​the drone; the wind speed and direction sensor is used to collect wind speed data in the flight area of ​​the drone; and the temperature and humidity sensor is used to collect temperature data in the flight area of ​​the drone.

[0064] Furthermore, the weather station sensors are the core unit for high-altitude data acquisition, including rain and snow sensors, wind speed and direction sensors, and temperature and humidity sensors. The rain and snow sensors monitor 24-hour rainfall and snowfall, generating rainfall and snowfall data; the wind speed and direction sensors collect wind speed and direction data, generating wind volume data; and the temperature and humidity sensors monitor ambient temperature and humidity, generating temperature data. The weather station sensors are installed on a high-altitude wind-solar power platform, avoiding obstruction from buildings and human interference in lower-altitude areas, resulting in data that more closely approximates the actual flight environment of the drone.

[0065] In one optional implementation, the management platform is further configured to classify at least one of the meteorological data, including rainfall data, snowfall data, wind data, and temperature data, to obtain the meteorological index level of the corresponding meteorological data, and to establish a corresponding control relationship between the meteorological index level and the flight status of the UAV, so as to generate UAV control commands based on the corresponding control relationship; the flight status includes normal flight and take-off and landing status, return status, and forced landing status.

[0066] Furthermore, the management platform has a built-in preset algorithm to quantify and classify four types of meteorological data (rainfall data, snowfall data, wind volume data, and temperature data).

[0067] Table 1 shows the corresponding control relationship between the meteorological index levels of rainfall data and the flight status of UAVs. The rainfall data is divided into 6 levels according to the 24-hour rainfall (e.g., light rain <10mm is rain level 1, and torrential rain ≥250mm is rain level 6).

[0068] Table 1

[0069]

[0070] Table 2 shows the corresponding control relationship between meteorological index levels of snowfall data and UAV flight status. Snowfall data is divided into 6 levels according to 24-hour snowfall (e.g., light snow <2.5mm is snow level 1, and heavy snow ≥30mm is snow level 6).

[0071] Table 2

[0072]

[0073] Table 3 shows the corresponding control relationship between the meteorological index levels of temperature data and the flight status of UAVs. The temperature data is divided into 8 levels according to the temperature range (e.g., extreme cold <-40℃ is temperature level 1, and extreme heat >50℃ is temperature level 8).

[0074] Table 3

[0075]

[0076] Table 4 shows the corresponding control relationship between the meteorological index level of wind volume data and the flight status of UAV. The wind volume data is divided into 12 levels according to wind speed (e.g., light wind 0.3-1.5m / s is wind level 1, and typhoon >32.6m / s is wind level 12).

[0077] Table 4

[0078]

[0079] The mapping rules between each meteorological indicator level and the UAV flight status include: when a single meteorological indicator is ≤ the threshold level (e.g., rainfall ≤ rain level 2, wind force ≤ wind level 6), the UAV maintains its original mission and performs normal flight and take-off and landing; when a single meteorological indicator exceeds the threshold level (e.g., rainfall ≥ rain level 3, wind force ≥ wind level 7), the UAV is triggered to return to the hangar along the preset route and performs return flight; when a single meteorological indicator reaches the danger level (e.g., rainfall ≥ rain level 4, wind force ≥ wind level 8), the UAV immediately finds the nearest safe area to land and performs forced landing flight.

[0080] Please see Figure 2The diagram illustrates the corresponding control relationship between four types of meteorological data and the drone's status. In this embodiment, the control command is determined layer by layer in the order of rainfall, snowfall, temperature, and wind volume. First, after the management platform successfully receives the rainfall, snowfall, temperature, and wind volume data collected by the meteorological station sensors, it initiates the decision-making process. The first layer judges the rainfall data. If the rainfall reaches level 3, it directly enters the branch for issuing the drone's return-to-home command; if the rainfall is level 4-6, it directly enters the branch for issuing the drone's forced landing command; only when the rainfall is level 1-2 will the subsequent snowfall judgment logic continue to be executed. The second layer judges the snowfall data. When the rainfall has been filtered to level 1-2, if the snowfall reaches level 3, it enters the branch for issuing the drone's return-to-home command; if the snowfall is level 4-6, it enters the branch for issuing the drone's forced landing command; only when the snowfall is level 1-2 will the temperature judgment logic continue to be executed. The third layer is based on temperature data. When rainfall and snowfall have been filtered to rain level 1-2 and snow level 1-2, if the temperature is level 2 or 7 (e.g., level 2 represents -10℃ to -5℃, level 7 represents 35℃ to 40℃, etc., extreme critical ranges), the branch that issues the drone return command will be entered. If the temperature is level 1 or 8 (e.g., level 1 represents ≤-40℃, level 8 represents ≥50℃, etc., extremely cold / extremely hot ranges), the branch that issues the drone forced landing command will be entered. Only when the temperature is level 3-6 (relatively suitable range, e.g., level 3 represents -5℃ to 0℃, level 6 represents 30℃ to 35℃), the wind volume (i.e., wind force) judgment logic will continue to be executed. The fourth layer assesses wind data. When rainfall, snowfall, and temperature are filtered to rain level 1-2, snow level 1-2, and temperature level 3-6, if the wind force reaches level 7, the system initiates a return-to-home command; if the wind force is level 8-12, it initiates a forced landing command; only when the wind force is level 1-6 (a relatively safe range, such as light breeze 1-2, light to strong wind 3-6) does the management platform output normal flight and take-off / landing commands. Therefore, in this embodiment, the command output rule is that as long as any layer determines that a return-to-home or forced landing condition is triggered, the process directly jumps to the corresponding command output; only when rainfall, snowfall, temperature, and wind all meet the normal range (rain 1-2, snow 1-2, temperature 3-6, wind 1-6) are normal flight and take-off / landing commands executed. This reflects a safety control logic where weather conditions are the sole determinant, prioritizing drone flight safety.

[0081] In one alternative implementation, multiple ground repeaters are provided, and the multiple ground repeaters are deployed at corresponding distances to cover the meteorological data collection of the UAV's flight area.

[0082] Furthermore, in this embodiment, the multiple ground repeaters can be deployed at high points (such as mountain tops and ridges) with an altitude of ≥2000 meters, spaced 5-10 kilometers apart (adjusted according to terrain complexity), forming a chain-like coverage network. Multiple ground repeaters work together to cover the UAV flight area (such as border lines and mountain patrol routes), collecting meteorological data in the same area in parallel, avoiding data interruption due to single device failure. When the UAV flies to the coverage area of ​​different repeaters, it automatically switches to the repeater with the strongest signal to ensure data transmission continuity. This embodiment achieves differentiated collection of meteorological data at different altitudes and terrains within the flight area (such as wind differences between valleys and mountain tops) through multi-point deployment.

[0083] In one alternative implementation, the drone hangar also includes a hangar host computer;

[0084] The weather station sensor is connected to the ground-based repeater via a serial interface to transmit the collected meteorological data to the ground-based repeater.

[0085] The ground-based repeater is wirelessly connected to the hangar-based repeater to transmit the meteorological data to the hangar-based repeater via wireless signal;

[0086] The hangar-side repeater is connected to the hangar host computer via a serial port interface to transmit the meteorological data received from the ground-side repeater to the hangar host computer.

[0087] The host computer in the hangar connects to the management platform via an Ethernet interface to transmit the meteorological data to the management platform and receive control commands sent by the management platform.

[0088] Furthermore, the hangar's host computer acts as a local control hub, responsible for caching control commands issued by the management platform to avoid wireless link congestion. It parses the command type (such as return-to-home or forced landing) and forwards it to the hangar-side repeater according to the protocol format. The repeater then transmits the commands to the flight controller for flight status control. In addition, the hangar's host computer can also transmit UAV status data (such as location and battery level) back to the management platform to form a closed-loop control system.

[0089] In one alternative implementation, the drone also includes a flight controller;

[0090] The hangar-side repeater is also wirelessly connected to the airborne repeater to send the control command to the airborne repeater.

[0091] The airborne repeater is also connected to the flight controller via a serial interface to send control commands to the flight controller and control the flight status of the UAV.

[0092] Furthermore, after receiving control commands, the flight controller processes them according to the following priorities: first, the emergency landing command (highest priority, immediately aborts the mission); second, the return-to-home command (secondary priority, returns along the preset route); and third, the normal flight command (adjusts flight parameters, such as altitude and speed).

[0093] Please see Figure 3 The diagram illustrates the remote deployment and control process for relaying meteorological data from a drone. While the wind-solar power platform supplies power to the ground-based repeaters, meteorological data from sensors on the platform are connected to these repeaters via serial interfaces. Multiple ground-based repeaters may be deployed at relatively high altitudes at intervals, such as border patrol areas. These repeaters primarily perform positioning and data transmission during drone flight, wirelessly transmitting meteorological data to the hangar-based repeaters. The hangar-based repeaters then transmit data to the drone's host computer board via serial port, and finally via Ethernet to the backend management platform. After data analysis and processing, the platform issues corresponding control commands. The management platform sends drone control commands to the hangar host computer, which then sends the commands to the hangar-based repeaters via serial port, and finally to the onboard repeaters on the drone via wireless signal. The onboard repeaters then send the control commands to the drone's flight controller, which in turn controls the drone's flight status. Specifically, the weather station sensors are responsible for collecting key meteorological data such as rainfall, snowfall, wind speed, and temperature, and then transmitting this data to the ground-based repeater of the wind-solar power supply system via a serial interface. The ground-based repeater then transmits the received meteorological data to the UAV hangar-based repeater via a 2.4G or 1.4G frequency band wireless signal. Upon receiving the data, the UAV hangar-based repeater transmits the meteorological data to the hangar's host computer via a serial interface. The hangar-based host computer forwards the meteorological data to its local management platform via Ethernet. After receiving the meteorological data, the management platform analyzes and processes the data using built-in algorithms to determine the appropriate actions for the UAV (such as normal flight and takeoff / landing, return to base, or forced landing), and generates corresponding control commands. These commands are then sent back to the UAV hangar-based host computer. The UAV hangar-based host computer sends the control commands to the hangar-based repeater via a serial interface. The hangar-based repeater then transmits the control commands to the UAV's onboard repeater using a 2.4G or 1.4G frequency band wireless signal. The UAV-based repeater transmits received control commands to the UAV flight controller via a serial interface. The flight controller adjusts and controls the UAV's flight status according to the commands to ensure safe and stable flight according to the predetermined control strategy.

[0094] In summary, the technical solution provided in this embodiment can include the following beneficial effects:

[0095] 1. Through wireless signal communication and data transmission via three sets of repeaters (ground-end repeater, hangar-end repeater, and airborne repeater), it is not limited by 4G / 5G networks. Even in remote, high-altitude, border, and uninhabited areas where there is no network signal, it can ensure the smooth and accurate transmission of meteorological data signals, thereby ensuring that the flight status of the UAV can be accurately controlled based on real-time meteorological data.

[0096] 2. By setting the meteorological sensor on the ground relay system deployed above the preset altitude, there is no need to install the meteorological sensor on or near the drone hangar. This avoids the collision risk that the sensor may cause on the drone hangar, as well as the extra space and complex design required for pole installation. It simplifies the structural design, makes installation and deployment more convenient, and reduces human interference to the sensor.

[0097] 3. The ground relay system (including wind and solar power platforms and meteorological station sensors) is deployed in high-altitude areas above the altitude threshold. These areas have fewer obstructions and the meteorological conditions are closer to the actual flight environment of UAVs. Therefore, the collected meteorological data such as wind, rain, snow, and temperature are more accurate, providing a more reliable basis for the flight control of UAVs and helping to improve the safety and reliability of UAV flights.

[0098] 4. Multiple ground repeaters and wind and solar power platforms can be easily deployed in multiple areas. Based on the area where the UAV flies, the meteorological information of that area can be accurately determined, thereby achieving precise positioning and flight control of the UAV and enhancing the system's adaptability to different flight environments.

[0099] 5. The system can flexibly add or remove data collected by different meteorological sensors according to actual conditions, adjust the constraints of meteorological data for different regions, and flexibly adjust the control algorithm according to the UAV's flight status to achieve better control of the UAV's flight status, giving the system good flexibility and scalability.

[0100] According to an embodiment of the present invention, a method for relaying and controlling meteorological data from unmanned aerial vehicles (UAVs) is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0101] This embodiment provides a method for relaying and controlling UAV meteorological data, which can be used in the aforementioned management platform. Figure 4 This is a flowchart of a method for relaying and controlling meteorological data from an unmanned aerial vehicle (UAV) according to an embodiment of the present invention, such as... Figure 4 As shown, the process includes the following steps:

[0102] Step S401: Obtain meteorological data collected by the weather station sensors through the wireless link formed by the hangar-end repeater and the ground-end repeater.

[0103] Furthermore, in this embodiment, the meteorological station sensors are deployed on the wind-solar power supply platform of the ground-based relay system, responsible for collecting real-time meteorological data in the UAV's flight area, including rainfall, snowfall, wind speed, and temperature. These sensors are connected to the ground-based repeater via a serial interface, transmitting the collected meteorological data to the ground-based repeater. The ground-based repeater then transmits the data to the UAV hangar-based repeater via a 2.4G or 1.4G frequency band wireless signal. After receiving the data, the hangar-based repeater transmits the data to the hangar host computer via a serial interface, and the hangar host computer then transmits the data to the management platform via Ethernet. This process ensures stable transmission of meteorological data from the collection point to the management platform, enabling accurate data acquisition even in remote areas or areas without 4G / 5G networks.

[0104] Step S402: Generate UAV control commands based on the meteorological data.

[0105] In one optional implementation, step S402 includes:

[0106] At least one of the meteorological data, including rainfall, snowfall, wind, and temperature, is classified into different levels to obtain the meteorological index level of the corresponding meteorological data. A corresponding control relationship between the meteorological index level and the flight status of the UAV is established to generate UAV control commands based on the corresponding control relationship. The flight status includes normal flight and take-off and landing status, return status, and forced landing status.

[0107] Furthermore, after receiving meteorological data, the management platform classifies at least one of the following meteorological data points—rainfall, snowfall, wind, and temperature—into meteorological index levels. For example, rainfall data can be categorized into light rain, moderate rain, heavy rain, and torrential rain; wind data can be categorized into gentle breeze, light wind, light wind, moderate breeze, strong wind, gale, strong wind, storm, and typhoon. Based on these meteorological index levels, the management platform establishes a corresponding control relationship with the UAV's flight status. Flight status includes normal flight and takeoff / landing, return-to-home, and emergency landing. According to the real-time meteorological data levels, the management platform generates corresponding UAV control commands to ensure flight safety and mission execution under different weather conditions.

[0108] In step S403, the control command is sent to the UAV through the wireless link formed by the hangar-end repeater and the airborne repeater to control the flight status of the UAV.

[0109] Furthermore, the drone control commands generated by the management platform are sent back to the hangar's host computer via Ethernet. The hangar's host computer then sends the control commands to the hangar-side repeater via a serial interface. The hangar-side repeater transmits the control commands to the drone's onboard repeater via 2.4G or 1.4G frequency wireless signals. The onboard repeater then transmits the control commands to the drone's flight controller via a serial interface. Based on the received control commands, the flight controller adjusts and controls the drone's flight status. For example, if the management platform determines that the current weather conditions are suitable for normal flight, the flight controller will maintain the drone's normal flight and takeoff / landing status; if the weather conditions are severe, the flight controller will execute a return-to-home or forced landing command to ensure the drone's safety. This process achieves real-time control from the management platform to the drone, ensuring that the drone can respond correctly based on real-time weather data.

[0110] In summary, the technical solution provided in this embodiment can include the following beneficial effects:

[0111] 1. Through wireless signal communication and data transmission via three sets of repeaters (ground-end repeater, hangar-end repeater, and airborne repeater), it is not limited by 4G / 5G networks. Even in remote, high-altitude, border, and uninhabited areas where there is no network signal, it can ensure the smooth and accurate transmission of meteorological data signals, thereby ensuring that the flight status of the UAV can be accurately controlled based on real-time meteorological data.

[0112] 2. By setting the meteorological sensor on the ground relay system deployed above the preset altitude, there is no need to install the meteorological sensor on or near the drone hangar. This avoids the collision risk that the sensor may cause on the drone hangar, as well as the extra space and complex design required for pole installation. It simplifies the structural design, makes installation and deployment more convenient, and reduces human interference to the sensor.

[0113] 3. The ground relay system (including wind and solar power platforms and meteorological station sensors) is deployed in high-altitude areas above the altitude threshold. These areas have fewer obstructions and the meteorological conditions are closer to the actual flight environment of UAVs. Therefore, the collected meteorological data such as wind, rain, snow, and temperature are more accurate, providing a more reliable basis for the flight control of UAVs and helping to improve the safety and reliability of UAV flights.

[0114] 4. Multiple ground repeaters and wind and solar power platforms can be easily deployed in multiple areas. Based on the area where the UAV flies, the meteorological information of that area can be accurately determined, thereby achieving precise positioning and flight control of the UAV and enhancing the system's adaptability to different flight environments.

[0115] 5. The system can flexibly add or remove data collected by different meteorological sensors according to actual conditions, adjust the constraints of meteorological data for different regions, and flexibly adjust the control algorithm according to the UAV's flight status to achieve better control of the UAV's flight status, giving the system good flexibility and scalability.
