Description

Technical Field

[0001] This invention relates to the field of logistics technology, specifically to a hydrogen-powered drone logistics system based on a distributed hydrogen production network. Background Technology

[0002] Unmanned aerial vehicle (UAV) logistics systems rely on UAVs as transportation carriers to achieve efficient cargo flow through systematic scheduling and management, ground support, and technical assistance, demonstrating significant potential in terms of efficiency, cost, and scenario adaptability. However, their large-scale application is limited by the bottleneck of endurance. Currently, most mainstream logistics UAVs rely on lithium batteries as their power source, which have significant shortcomings in energy density, cycle life, and energy replenishment efficiency, resulting in energy storage technology lagging behind mission requirements.

[0003] Hydrogen-powered drones, leveraging the high energy density of hydrogen fuel and the efficient energy conversion characteristics of fuel cells, have opened up new avenues for overcoming range limitations. They can carry more effective energy within the same fuselage weight, and the long design life of fuel cells and rapid refueling significantly improve operational efficiency. However, hydrogen-powered drone logistics faces constraints related to fuel sources. Hydrogen transportation suffers from low storage and transportation efficiency, insufficient hydrogen refueling station coverage, high safety requirements, and high economic costs, directly limiting the large-scale application of hydrogen energy in logistics systems. Existing similar technologies focus on hydrogen production through non-pure aqueous solution electrolysis, and an integrated solution for hydrogen production, refueling, and transportation in logistics scenarios has not yet been formed.

[0028] The dynamic scheduling module automatically instructs the hydrogen-powered drone to return to the nearest integrated photovoltaic hydrogen production and refueling smart airport for refueling when its energy level falls below a threshold.

[0029] Furthermore, the automated express delivery network and the distributed smart airport network achieve data interoperability through 5G / satellite communication, supporting remote appointment for senders and ID card collection for recipients.

[0030] Furthermore, the system is compatible with traditional logistics networks and can interface with existing express delivery distribution centers.

[0031] Furthermore, the photovoltaic hydrogen production system employs non-pure aqueous solution electrolysis technology, allowing the direct production of hydrogen from rainwater or groundwater, thereby reducing water purification costs.

[0043] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0044] like Figures 1 to 6 As shown, a hydrogen-powered drone logistics system based on a distributed hydrogen production network realizes on-site hydrogen production and replenishment through a distributed intelligent airport network. Combining the high-efficiency transportation capabilities of hydrogen-powered drones with the intelligent coordination of the dispatch center, a green, efficient, and low-cost logistics solution is constructed. The specific technical solution is as follows:

[0045] The distributed intelligent airport network 1 is the core infrastructure of this system. It adopts a geographically gridded layout, deploying multiple photovoltaic-powered hydrogen production and refueling integrated intelligent airports 2 in key locations such as cities and surrounding areas, transportation hubs, and remote regions. Each airport has a service radius covering 50-100 kilometers, forming a seamless logistics coverage network through multi-node interconnection. Taking a certain urban cluster as an example, one airport is deployed every 50 kilometers in the main urban area, and one airport is deployed every 80-100 kilometers in suburban and county areas, ensuring that hydrogen-powered drones can refuel nearby at any time during transportation.

[0046] Each integrated photovoltaic hydrogen production and refueling smart airport 2 integrates three core modules: a photovoltaic hydrogen production system 21, a smart hydrogen refueling station 22, and a drone hangar 23. Specific implementation details are as follows:

[0047] The photovoltaic hydrogen production system 21 is the "source" of hydrogen energy, achieving green hydrogen production through solar energy conversion and electrolysis. Specifically, it includes:

[0048] The 211 solar photovoltaic array uses high-efficiency monocrystalline silicon photovoltaic panels. The installation angle is designed according to the sunlight conditions of the airport's location (e.g., a tilt angle of 30°±5° for areas at 30° North latitude), and it is equipped with a solar tracking system that can track the sun's position in real time, improving the light energy conversion efficiency by 15-20%. The installed capacity of the photovoltaic array is configured according to the airport's hydrogen energy demand, typically 300-800kW for a single airport, meeting the daily hydrogen production requirement of 50-200kg.

[0049] The 212 water electrolysis hydrogen production unit employs non-pure aqueous solution electrolysis technology, eliminating the need for complex water source purification. It can directly utilize rainwater, groundwater, or industrial circulating water as electrolysis feedstock, significantly reducing water resource costs. The unit is equipped with a PEM electrolyzer (proton exchange membrane electrolyzer) with an electrolysis efficiency ≥75%, and a single-cell hydrogen production capacity of 50-150 Nm³. 3 It has a speed of / h and a fast response speed, and can dynamically adjust the hydrogen production rate according to the photovoltaic power generation to achieve real-time matching of "photovoltaic-electricity-hydrogen".

[0050] The hydrogen generated by electrolysis in the hydrogen purification and storage unit 213 undergoes purification processes such as drying, deoxygenation, and decarbonization to achieve a purity of 99.999%, meeting the requirements for use in hydrogen-powered drone fuel cells. The purified hydrogen is then compressed to 35 MPa or 70 MPa by a compressor and stored in a high-pressure gaseous hydrogen storage device 221. The hydrogen storage capacity for a single airport is designed to be 100-500 kg, which can meet the refueling needs of 50-200 hydrogen-powered drones.

[0051] The intelligent hydrogen refueling station 22 is responsible for providing rapid refueling services for hydrogen-powered drones. Its core components include:

[0052] The high-pressure gaseous hydrogen storage device 221 adopts carbon fiber wound hydrogen storage cylinder assembly, which has high strength and lightweight characteristics, can withstand pressure above 35MPa, and is equipped with pressure sensor, temperature sensor and safety valve to monitor the hydrogen storage status in real time. When the pressure is abnormal or the temperature is too high, the pressure relief protection is automatically triggered to ensure storage safety.

[0053] The fast hydrogen refueling interface 222 is compatible with the fuel cell system of hydrogen-powered drones and adopts automatic docking technology. After landing, the hydrogen-powered drone can automatically connect to the interface via the hangar robotic arm, achieving "stop and refuel immediately". The hydrogen refueling process is precisely regulated by the flow control module. The amount of hydrogen refueling for a single drone is set according to mission requirements, and the refueling time is only 3-5 minutes, which is comparable to the refueling speed of a gasoline car and much faster than the charging time of lithium battery drones.

[0054] Drone hangar 23 serves as a "dock" and "maintenance station" for hydrogen-powered drones, with the following specific functions:

[0055] The 231 drone parking platform adopts a modular design and can simultaneously park 5-20 hydrogen-powered drones. The platform surface is equipped with positioning markers and buffer devices to ensure accurate drone parking and reduce impact damage.

[0056] The maintenance and testing device 232 integrates technologies such as visual recognition and sensor detection. After the drone docks, it automatically performs a comprehensive inspection of the fuselage structure, fuel cell status, hydrogen pipeline sealing, propeller performance, etc. The inspection data is uploaded to the dispatch center 6 in real time. If a fault is found (such as a slight leak in the hydrogen pipeline or abnormal battery output), a maintenance command is automatically triggered and the drone is marked as "to be maintained".

[0057] The climate control unit 233 controls the temperature and humidity inside the hangar through air conditioning, dehumidifier and insulation layer. The temperature is controlled at 15-30℃ and the humidity is ≤60%. It can adapt to different environmental conditions such as high temperature, severe cold and high humidity, and avoid the impact of extreme weather on drones and hydrogen energy equipment.

[0058] Hydrogen-powered drones are the core carriers for cargo transportation, and their design and operation directly affect logistics efficiency. Specific implementation details are as follows:

[0059] The hydrogen-powered drone 3 is equipped with a hydrogen fuel cell power system 31. This system uses hydrogen as fuel and generates electricity through an electrochemical reaction to drive the motor. The energy density is ≥500Wh / kg, which is much higher than that of lithium batteries (usually ≤250Wh / kg). Taking a 10kg payload drone as an example, it can achieve a range of 200-300 kilometers after a single hydrogen refueling, which is 1-2 times higher than that of lithium battery drones of the same level. Moreover, the increase in payload has a very small impact on the range (when the payload increases from 10kg to 15kg, the range only decreases by 5-8%).

[0060] The drone is equipped with an energy management unit 32, which monitors data such as fuel cell output power, remaining hydrogen, and flight energy consumption in real time. It also dynamically adjusts the flight attitude (e.g., optimizing the climb angle and reducing the cruise speed) based on parameters such as flight speed and altitude to ensure maximum energy efficiency. Simultaneously, the unit incorporates multiple safety mechanisms: it automatically issues a warning when the remaining hydrogen level falls below 20%; it forcibly triggers a return-to-home command when the level falls below 10%; and if abnormal fuel cell discharge is detected, it immediately cuts off power output and deploys a backup parachute to ensure flight safety.

[0061] The drone is equipped with a modular cargo compartment, supporting automatic loading and unloading of standard express boxes (≤30cm×20cm×15cm). The cargo compartment has built-in cushioning pads and positioning buckles to prevent damage to goods during transportation. During flight, the drone uses GPS and Beidou dual-mode positioning, combined with an IMU (Inertial Measurement Unit) to achieve centimeter-level navigation accuracy, ensuring precise arrival above the target express locker.

[0062] Dispatch Center 6 is the "brain" of the system, achieving full-process control through algorithm-based interaction with real-time data. Its specific functions are implemented as follows:

[0063] Module 61 of the route planning module generates the optimal transportation route based on multi-dimensional data:

[0064] Real-time access to meteorological data helps avoid areas affected by severe weather such as heavy rain and strong winds (wind speed ≥10m / s);

[0065] Based on the hydrogen reserves of each airport (when the hydrogen reserves of an airport are less than 30%, priority will be given to dispatching drones from other airports);

[0066] The maximum range is calculated based on the remaining energy of the hydrogen-powered drone, ensuring that the route includes airport nodes where refueling is possible.

[0067] For example, the straight-line distance from the parcel locker 4 at the sending end to the parcel locker 5 at the receiving end is 180 kilometers. The system will plan a path from the sending end to Airport A (recharging) to the receiving end. Airport A is 80 kilometers away from the sending end and 100 kilometers away from the receiving end. It also has sufficient hydrogen storage to meet the recharging needs of drones.

[0068] The dynamic scheduling module 62 enables real-time monitoring and emergency adjustments:

[0069] The system tracks the location, energy status, and cargo information of all hydrogen-powered drones in real time. When a drone's energy level falls below a threshold (e.g., 25%), it automatically commands the drone to return to the nearest integrated photovoltaic hydrogen production and refueling smart airport for refueling.

[0070] If an airport experiences a sudden malfunction (such as a photovoltaic system shutdown), the scheduling priority of drones at surrounding airports will be immediately adjusted to temporarily take over the transportation tasks of that airport.

[0071] It supports manual intervention, allowing users to manually adjust routes and priorities when encountering special needs such as emergency medical supply transportation.

[0072] The automated courier network interacts with users through parcel lockers 4 at the sending end and parcel lockers 5 at the receiving end. Specific implementation details are as follows:

[0073] User interaction features: Customers can complete the ordering, weighing, and payment process through the locker screen or mobile APP. The locker will automatically print the waybill and open the storage compartment. Customers can open the corresponding storage compartment to retrieve their packages by recognizing their ID card, entering the pickup code, or facial recognition. The entire process requires no human intervention.

[0074] Data communication guarantee: The express locker and the distributed smart airport network 1 achieve real-time data communication through 5G communication, while remote areas are supplemented by satellite communication to ensure the real-time uploading and synchronization of data such as sending information, cargo status, and pickup records.

[0075] Compatible design: The express locker supports the storage of goods of different sizes. The smallest storage compartment is 10cm×10cm×5cm (suitable for documents), and the largest is 50cm×40cm×30cm (suitable for small parcels), which can meet most of the needs of daily logistics.

[0076] This system does not completely replace the traditional logistics network, but rather achieves compatibility with the existing system through interface design:

[0077] Integration with existing express delivery distribution centers: Through standardized data interfaces, the system's transportation information is synchronized to the traditional logistics management system, supporting a hybrid delivery model of "drone + ground transportation" (such as drones transporting goods from remote areas to county-level distribution centers, and then ground vehicles delivering them to townships).

[0078] Future expansion capabilities: The service range can be expanded by adding airport nodes, or the hydrogen production system can be upgraded (such as by introducing solar thermal assisted electrolysis technology) to improve hydrogen production efficiency. It can also be adapted to hydrogen-powered drones with larger payloads (such as 50kg class) to meet the needs of transporting large cargo.

[0079] In actual operation, this system demonstrates significant advantages over traditional lithium battery drone logistics systems:

[0080] Endurance and efficiency: Hydrogen-powered drones have a single-charge range of 200-300 kilometers and an average of 8-12 effective flights per day, which is more than 50% faster than lithium battery drones (4-6 flights per day).

[0081] Cost control: Photovoltaic hydrogen production eliminates hydrogen transportation costs (accounting for about 30-40% of the cost of traditional hydrogen energy), and the fuel cell has a design life of more than 10,000 hours, far exceeding the 2,000-3,000 hours of lithium batteries, reducing long-term operating costs by 40-60%.

[0082] Green and environmentally friendly: The entire process uses solar energy to produce hydrogen, and the hydrogen fuel cell power generation only produces water with no carbon emissions. The carbon emissions for transporting 1kg of goods are reduced by more than 90% compared to transportation by fuel vehicles, and by 50-70% compared to lithium battery drones (which rely on grid charging) (depending on the proportion of clean energy in the grid).

[0083] In summary, this invention solves the endurance bottleneck and hydrogen storage and transportation challenges of drone logistics by deeply integrating a distributed hydrogen production network with hydrogen-powered drones, providing a new path for the green and efficient development of the logistics industry.

[0084] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.

Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.
