Therefore, the features defined with “first”, “second” can explicitly or implicitly include at least one of the features.

[0029] Hydrogen fuel cell unmanned aerial vehicles have become an important direction of green aviation development due to advantages such as high endurance, high energy density, strong environmental adaptability and long service life, and are widely used in infrastructure inspection, wide-area mapping, emergency rescue and other operation scenarios. With the increasing demand for long-time and large-range operation of hydrogen fuel cell unmanned aerial vehicles, hydrogen refueling mode has become a key factor restricting work efficiency. The existing hydrogen refueling mode mainly relies on replacing hydrogen storage cylinders or going to fixed hydrogen refueling stations, and the distribution of fixed hydrogen refueling stations is limited. When the unmanned aerial vehicle works at a work point far away from the hydrogen refueling station, it is difficult to achieve rapid and convenient hydrogen refueling, and the work efficiency of the hydrogen fuel cell unmanned aerial vehicle is low and the work range is small.

[0030] In actual application, the unmanned aerial vehicle hydrogen storage cylinder has high requirements for the ambient temperature during hydrogen refueling. Excessive temperature rise will cause irreversible damage to the carbon fiber material of the hydrogen storage cylinder, affecting the operation safety of the hydrogen fuel cell unmanned aerial vehicle. However, the heat exchanger refrigeration system commonly used at present occupies a large area and is not suitable for flexible movement. The pre-cooling system, as a key system to ensure hydrogen refueling safety, is not suitable for mobile hydrogen refueling devices. In addition, the current mobile hydrogen refueling devices are mainly designed for hydrogen fuel cell vehicle hydrogen refueling, and the volume of the hydrogen storage cylinder of the hydrogen fuel cell unmanned aerial vehicle is much smaller than that of the hydrogen fuel cell vehicle. The current mobile hydrogen refueling device is not convenient for hydrogen refueling of the unmanned aerial vehicle hydrogen storage cylinder, and due to the large volume and high energy consumption of the hydrogen storage, it is not convenient to flexibly reach various work points of the unmanned aerial vehicle, and cannot be refueled nearby, which becomes an important factor restricting the work efficiency of the unmanned aerial vehicle.

[0031] Therefore, one or more embodiments of the present application provide a vehicle-mounted UAV rapid hydrogenation system and method, which can solve the above problems, and the vehicle-mounted UAV rapid hydrogenation system can flexibly reach various work points of the UAV, realize near-distance efficient hydrogenation of the hydrogen fuel cell UAV, and improve the work efficiency of the hydrogen fuel cell UAV.

[0032] Please refer to Figure 1 One embodiment of the present application provides a vehicle-mounted UAV rapid hydrogenation system, which at least comprises a pre-cooling system 10, a parking platform 11 and a vehicle-mounted high-pressure hydrogen storage bottle group 12, the vehicle-mounted high-pressure hydrogen storage bottle group 12 comprises a plurality of vehicle-mounted high-pressure hydrogen storage bottles 121 and a plurality of low-temperature high-pressure hydrogen storage bottles 122, and the pre-cooling system 10 comprises a hydrogen storage bottle built-in heat exchange pipe 101, a refrigeration unit and a cold carrier.

[0033] The vehicle-mounted high-pressure hydrogen storage bottle group 12 is connected with the parking platform 11, the vehicle-mounted high-pressure hydrogen storage bottle group 12 is used to provide hydrogen gas for the parking platform 11, and the parking platform 11 is used to hydrogenate the hydrogen storage bottle group of the UAV to be hydrogenated.

[0034] The refrigeration unit is used to refrigerate the cold carrier, and the refrigerated cold carrier is introduced into the hydrogen storage bottle built-in heat exchange pipe 101, the hydrogen storage bottle built-in heat exchange pipe 101 is arranged in the low-temperature high-pressure hydrogen storage bottle 122, and the hydrogen storage bottle built-in heat exchange pipe 101 is used to exchange heat with the low-temperature high-pressure hydrogen storage bottle 122.

[0035] Please refer to Figure 2 The hydrogen storage bottle built-in heat exchange pipe 101 is provided with an input port 1010 and an output port 1011, the input port 1010 is used to introduce the cold carrier refrigerated by the refrigeration unit, and the output port 1011 is used to output the heat-exchanged cold carrier to the refrigeration unit. Specifically, in the heat exchange process, the cold carrier refrigerated by the refrigeration unit is introduced into the hydrogen storage bottle built-in heat exchange pipe 101 through the input port 1010, and exchanges heat with the hydrogen gas of the low-temperature high-pressure hydrogen storage bottle 122, and the heat-exchanged cold carrier is output from the output port 1011 back to the refrigeration unit, so as to realize the pre-cooling treatment of the low-temperature high-pressure hydrogen storage bottle 122.

[0036] In the embodiment, by arranging the hydrogen storage bottle built-in heat exchange pipe 101 in the low-temperature high-pressure hydrogen storage bottle 122, the footprint of the pre-cooling system 10 can be reduced. By replacing the traditional external heat exchanger with the hydrogen storage bottle built-in heat exchange pipe 101, the footprint of the pre-cooling system 10 in the vehicle-mounted unmanned aerial vehicle rapid hydrogenation system is reduced, the flexibility of the vehicle-mounted unmanned aerial vehicle rapid hydrogenation system is improved, the near-distance efficient hydrogenation of the hydrogen fuel cell unmanned aerial vehicle is realized, and the working efficiency of the hydrogenation-ready unmanned aerial vehicle is further improved. In addition, directly pre-cooling the hydrogen by the cold carrier in the hydrogen storage bottle built-in heat exchange pipe 101 can also reduce the power consumption of the refrigerator.

[0037] In the embodiment, the vehicle-mounted high-pressure hydrogen storage bottle group 12 is divided into a vehicle-mounted high-pressure hydrogen storage bottle 121 and a low-temperature high-pressure hydrogen storage bottle 122, which can freely switch the hydrogen injection source of the hydrogenation-ready unmanned aerial vehicle according to the ambient temperature. When the ambient temperature is low, the vehicle-mounted high-pressure hydrogen storage bottle 121 is directly used for hydrogen delivery, avoiding unnecessary pre-cooling resource consumption. When the ambient temperature is high, the low-temperature high-pressure hydrogen storage bottle 122 after pre-cooling is used for hydrogen delivery, avoiding damage to the carbon fiber material caused by the rapid temperature rise inside the unmanned aerial vehicle hydrogen storage bottle during hydrogenation, ensuring the safety and reliability of hydrogenation in high-temperature environments.

[0038] In the embodiment, the above-mentioned vehicle-mounted unmanned aerial vehicle rapid hydrogenation system can be used for hydrogenation and transportation of hydrogen fuel cell unmanned aerial vehicles, and can flexibly reach various work points of unmanned aerial vehicles, realizing near-distance efficient hydrogenation of hydrogenation-ready unmanned aerial vehicles, saving time and energy for unmanned aerial vehicles to go to hydrogenation stations, and improving the working efficiency and use range of hydrogen fuel cell unmanned aerial vehicles. At the same time, the setting of the parking platform provides an operation platform for delivering hydrogen and a landing platform for landing unmanned aerial vehicles for hydrogenation-ready unmanned aerial vehicles, enhancing the convenience and flexibility of the vehicle-mounted unmanned aerial vehicle rapid hydrogenation system. It should be noted that the vehicle-mounted mode taking the hydrogen fuel cell vehicle as an example is only a movable implementation mode of the vehicle-mounted unmanned aerial vehicle rapid hydrogenation system, and other movable hydrogenation modes can also be selected according to actual needs and technical development, which is not limited in the present application.

[0039] In one embodiment, please refer to Figure 3The vehicle-mounted unmanned aerial vehicle rapid hydrogenation system further comprises a fuel cell stack system 23, a power conversion system 24, a control system 25, and a compression system 26. The control system 25 comprises a fuel cell gas taking control panel and a sequential hydrogenation control panel. Specifically, the fuel cell gas taking control panel is used to connect the fuel cell stack system 23 and the vehicle-mounted high-pressure hydrogen storage bottle group 22, and the sequential hydrogenation control panel is used to determine the vehicle-mounted high-pressure hydrogen storage bottle 221 to be hydrogenated or pressurized in the vehicle-mounted high-pressure hydrogen storage bottle group 22, or to determine the low-temperature high-pressure hydrogen storage bottle 222 to be hydrogenated; the fuel cell stack system 23 is used to convert the chemical energy of the hydrogen gas provided by the vehicle-mounted high-pressure hydrogen storage bottle group 22 into electrical energy and transmit the electrical energy to the power conversion system 24; the power conversion system 24 is used to convert the generated electrical energy into electrical power, and the compression system 26 is used to pressurize the vehicle-mounted high-pressure hydrogen storage bottle group 22. Preferably, the compression system 26 can directly use a compressor.

[0040] In the embodiment, the vehicle-mounted high-pressure hydrogen storage bottle group 22 and the fuel cell stack system 23 are used to provide the system with an electrical energy source, thereby saving the system energy consumption and equipment cost. Specifically, the hydrogen gas in the vehicle-mounted high-pressure hydrogen storage bottle group 22 is transmitted to the fuel cell stack system 23, and the fuel cell stack system 23 converts the chemical energy of the hydrogen gas into electrical energy. The generated electrical energy is converted into electrical power suitable for the devices such as the compression system 26, the pre-cooling system 20, and the parking platform 21 by the power conversion system 24. By directly using the electrical energy suitable for the hydrogen gas generation system through the fuel cell stack system 23 and the power conversion system 24, the system energy consumption is saved, and the integration and portability of the vehicle-mounted unmanned aerial vehicle rapid hydrogenation system are further improved.

[0041] In the embodiment, the vehicle-mounted unmanned aerial vehicle rapid hydrogenation system further comprises a hydrogen delivery stop valve group, which comprises a first stop valve group and a first one-way valve group. The first stop valve group comprises a plurality of first stop valves, and the first one-way valve group comprises a plurality of first one-way valves. The hydrogen delivery stop valve group is used to connect the vehicle-mounted high-pressure hydrogen storage bottle group 22 and the sequential hydrogenation control panel of the control system 25. The hydrogen delivery stop valve group and the sequential hydrogenation control panel can transmit the hydrogen gas in the vehicle-mounted high-pressure hydrogen storage bottle group 22 to the unmanned aerial vehicle hydrogen storage bottle group for hydrogen injection operation of the unmanned aerial vehicle to be hydrogenated, or can transmit the hydrogen gas in the vehicle-mounted high-pressure hydrogen storage bottle group 22 back to the vehicle-mounted high-pressure hydrogen storage bottle group 22 after being pressurized by the compression system 26 to realize the pressurization of the vehicle-mounted high-pressure hydrogen storage bottle group 22.

[0042] In the present embodiment, the vehicle-mounted UAV rapid hydrogenation system further comprises an active pressurization stop valve group. The hydrogen delivery stop valve group needs to pass through the sequential hydrogenation control panel and the active pressurization valve group in sequence before transmitting the hydrogen in the vehicle-mounted high-pressure hydrogen storage bottle group 22 to the compression system 26. The active pressurization stop valve group comprises a second stop valve group and a second one-way valve group. The second stop valve group comprises a plurality of second stop valves, and the second one-way valve group comprises a plurality of second one-way valves. The active pressurization stop valve group is used to connect the sequential hydrogenation control panel and the vehicle-mounted high-pressure hydrogen storage bottle group 22.

[0043] In one embodiment, the vehicle-mounted high-pressure hydrogen storage bottle group is connected with a first passage, a second passage and a third passage. In the first passage, the vehicle-mounted high-pressure hydrogen storage bottle group is connected with the fuel cell stack system through the first passage, and the first passage is used to provide a hydrogen source for the fuel cell stack system to generate electric energy, wherein the first passage at least flows through the fuel cell hydrogen taking control panel. In the second passage, the vehicle-mounted high-pressure hydrogen storage bottle group is connected with the UAV hydrogen storage bottle group through the second passage, and the second passage is used to provide a hydrogen source for the UAV hydrogen storage bottle group to fill hydrogen, wherein the second passage at least flows through the hydrogen delivery stop valve group and the sequential hydrogenation control panel. In the third passage, the vehicle-mounted high-pressure hydrogen storage bottle group is connected with itself through the third passage, and the third passage is used to actively pressurize the vehicle-mounted high-pressure hydrogen storage bottle group, wherein the third passage at least flows through the hydrogen delivery stop valve group, the compression system, the sequential hydrogenation control panel and the active pressurization stop valve group.

[0044] In one embodiment, the vehicle-mounted high-pressure hydrogen storage bottle group comprises a first pressure sensor and a first temperature sensor, which are used to monitor the pressure and temperature in the vehicle-mounted high-pressure hydrogen storage bottle in real time. The UAV hydrogen storage bottle group of the UAV to be hydrogenated comprises a second pressure sensor and a second temperature sensor, which are used to monitor the pressure and temperature in the UAV hydrogen storage bottle in real time. Because the hydrogen has a negative Joule-Thomson coefficient and compression work during hydrogen filling, the temperature of the hydrogen in the UAV hydrogen storage bottle group will rise as the pressure in the bottle rises. Once it is monitored that the temperature of the vehicle-mounted high-pressure hydrogen storage bottle group or the UAV hydrogen storage bottle group exceeds 85°C, the filling is immediately stopped to avoid safety hazards.

The second passage is used for providing a hydrogen source for filling hydrogen for an unmanned aerial vehicle hydrogen storage bottle group (including unmanned aerial vehicle hydrogen storage bottles 801a, 801b and 801c).

[0049] It should be noted that for any vehicle-mounted high-pressure hydrogen storage bottle, there is a temperature sensor and a pressure sensor connected thereto for monitoring the temperature and pressure in the vehicle-mounted high-pressure hydrogen storage bottle. For any unmanned aerial vehicle hydrogen storage bottle, there is a temperature sensor, a pressure sensor connected thereto for monitoring the temperature and pressure in the unmanned aerial vehicle hydrogen storage bottle, and a hydrogen filling gun and a stop valve connected thereto for filling hydrogen into the current unmanned aerial vehicle hydrogen storage bottle.

The above-mentioned sequential hydrogen filling control panel can be used to determine the specific path connected to a certain vehicle-mounted high-pressure hydrogen storage bottle or a certain unmanned aerial vehicle hydrogen storage bottle.

[0050] In one embodiment, referring to FIGS. 5(a) and 5(b), the parking platform 30 includes one or more parking cabins 31, each of which is provided with an unmanned aerial vehicle lifting platform 310, an automatic clamping device 311, and a buffer rod 312 for providing space for the hydrogen filling operation of the hydrogen filling unmanned aerial vehicle 32. The unmanned aerial vehicle lifting platform 310, the automatic clamping device 311, and the buffer rod 312 are all arranged in the parking cabin 31, which is a closed cabin with an automatically opening and closing door. The unmanned aerial vehicle lifting platform 310 includes an automatic clamping device moving track 3110 for providing a parking platform for the hydrogen filling unmanned aerial vehicle 32. The automatic clamping device 311 is located on the automatic clamping device moving track 3110 for fixing the hydrogen filling unmanned aerial vehicle 32. The buffer rod 312 is fixed to the wall of the parking cabin 31 for resisting the force generated during the hydrogen filling operation of the hydrogen filling unmanned aerial vehicle 32.

[0051] Further, the vehicle-mounted unmanned aerial vehicle rapid hydrogenation system further comprises a hydrogenation system, an input end of the hydrogenation system is connected with the vehicle-mounted high-pressure hydrogen storage bottle group, and an output end of the hydrogenation system is connected with a hydrogenation gun 33, and hydrogen is injected into the unmanned aerial vehicle hydrogen storage bottle group through the hydrogenation gun 33. The parking cabin 31 is further provided with a hydrogenation gun moving track 330, the hydrogenation gun 33 is arranged on the hydrogenation gun moving track 330, and the hydrogenation gun 33 can move to the position of the unmanned aerial vehicle 32 to be hydrogenated through the hydrogenation gun moving track 330. Preferably, the parking platform 30 is arranged at the upper end of the vehicle compartment, so as to facilitate the parking of the unmanned aerial vehicle 32 to be hydrogenated.

[0052] Specifically, when it is identified that the unmanned aerial vehicle 32 to be hydrogenated is about to land, the parking cabin 31 door is automatically opened, the unmanned aerial vehicle 32 to be hydrogenated lands on the unmanned aerial vehicle lifting platform 310 in the parking cabin 31, the automatic clamping device 311 fixes the unmanned aerial vehicle 32 to be hydrogenated according to the position of the unmanned aerial vehicle 32 to be hydrogenated, the unmanned aerial vehicle lifting platform 310 can be automatically lifted to adjust the height of the hydrogenation port of the unmanned aerial vehicle 32 to be hydrogenated, so that the height position of the hydrogenation port of the unmanned aerial vehicle 32 to be hydrogenated is the same as that of the hydrogenation gun 33, the automatic clamping device 311 moves forward and backward on the automatic clamping device moving track 3110, so that the hydrogenation port of the unmanned aerial vehicle 32 to be hydrogenated is the same as the forward and backward position of the hydrogenation gun 33, the hydrogenation gun 33 is moved left and right on the hydrogenation gun moving track 330, the hydrogenation port of the unmanned aerial vehicle 32 to be hydrogenated is aligned with the hydrogenation gun 33 for hydrogen injection operation, and when the hydrogenation port of the unmanned aerial vehicle 32 to be hydrogenated is aligned with the hydrogenation gun 33, the buffer rod 312 extends from the wall surface of the parking cabin 31 to resist the force acting on the unmanned aerial vehicle when the hydrogenation gun 33 is inserted into the hydrogenation port of the unmanned aerial vehicle 32 to be hydrogenated.

[0054] Please refer to Figure 6 The application also provides a vehicle-mounted unmanned aerial vehicle rapid hydrogenation method, which is applied to the vehicle-mounted unmanned aerial vehicle rapid hydrogenation system of the first aspect and specifically comprises the following steps:

[0055] S1: acquiring the ambient temperature of the current work point of the unmanned aerial vehicle to be hydrogenated, judging whether the ambient temperature meets the precooling condition, and precooling the low-temperature high-pressure hydrogen storage bottle through the precooling system if it is judged that the ambient temperature meets the preset precooling condition;

[0056] S3: When the parking platform receives the unmanned aerial vehicle to be hydrogenated, connect the hydrogenation gun to the unmanned aerial vehicle hydrogen storage bottle group of the unmanned aerial vehicle to be hydrogenated, use the low-temperature high-pressure hydrogen storage bottle to provide hydrogen for the hydrogenation gun, and fill the unmanned aerial vehicle to be hydrogenated with hydrogen through the hydrogenation gun until the unmanned aerial vehicle hydrogen storage bottle group meets the preset temperature condition;

[0057] S5: When the unmanned aerial vehicle hydrogen storage bottle group meets the preset temperature condition, continue to use the vehicle-mounted high-pressure hydrogen storage bottle to provide hydrogen for the hydrogenation gun, and fill the unmanned aerial vehicle hydrogen storage bottle group with hydrogen through the hydrogenation gun.

[0058] In this embodiment, when the unmanned aerial vehicle to be hydrogenated has a hydrogenation demand, it is determined whether to use pre-cooling filling by judging whether the ambient temperature of the current unmanned aerial vehicle to be hydrogenated working point meets the preset pre-cooling condition. The pre-cooling condition is that the ambient temperature is greater than or equal to the preset pre-cooling temperature, which can be set according to actual conditions, and is preferably 15-20°C. Taking 15°C as the preset pre-cooling temperature as an example, if the ambient temperature is greater than or equal to 15°C, the pre-cooling filling mode is used, that is, the low-temperature high-pressure hydrogen storage bottle is pre-cooled by the pre-cooling system, and then the unmanned aerial vehicle hydrogen storage bottle group is provided with hydrogen by the low-temperature high-pressure hydrogen storage bottle, and then the unmanned aerial vehicle hydrogen storage bottle group is provided with hydrogen by the vehicle-mounted high-pressure hydrogen storage bottle. If the ambient temperature is less than 15°C, the normal temperature filling mode is used, that is, the unmanned aerial vehicle hydrogen storage bottle group is directly provided with hydrogen by the vehicle-mounted high-pressure hydrogen storage bottle.

[0059] Specifically, if the ambient temperature is greater than or equal to 15°C, the low-temperature high-pressure hydrogen storage bottle is pre-cooled by the pre-cooling system before the vehicle-mounted unmanned aerial vehicle rapid hydrogenation system reaches the unmanned aerial vehicle to be hydrogenated working site. When the parking cabin of the parking platform receives the unmanned aerial vehicle to be hydrogenated, the hydrogenation gun is connected to the unmanned aerial vehicle hydrogen storage bottle group of the unmanned aerial vehicle to be hydrogenated. First, the unmanned aerial vehicle to be hydrogenated is filled with hydrogen from the low-temperature high-pressure hydrogen storage bottle group through the hydrogenation gun. When the unmanned aerial vehicle hydrogen storage bottle group meets the preset temperature condition, the unmanned aerial vehicle to be hydrogenated is filled with hydrogen from the vehicle-mounted high-pressure hydrogen storage bottle group through the hydrogenation gun.

[0060] In this embodiment, the preset temperature condition is that the temperature of the unmanned aerial vehicle hydrogen storage bottle group is in the temperature range of-45° to-55°. Generally, when the unmanned aerial vehicle hydrogen storage bottle group is filled with hydrogen by using the low-temperature high-pressure hydrogen storage bottle, the unmanned aerial vehicle hydrogen storage bottle group is pre-cooled to-45°C to-55°C when the internal pressure of the unmanned aerial vehicle hydrogen storage bottle group reaches P / 5-P / 6. P is the nominal working pressure of the unmanned aerial vehicle hydrogen storage bottle group, which is 35-70 MPa. It should be noted that the hydrogenation system is not affected by the difference in the nominal working pressure of the unmanned aerial vehicle hydrogen storage bottle of the unmanned aerial vehicle to be hydrogenated.

[0061] In the embodiment, when the unmanned aerial vehicle hydrogen storage bottle group is filled with hydrogen by the vehicle-mounted high-pressure hydrogen storage bottle group, direct filling or two-stage filling pressure hydrogen injection mode can be used. Direct filling refers to providing hydrogen to the unmanned aerial vehicle hydrogen storage bottle group by a single vehicle-mounted high-pressure hydrogen storage bottle, and two-stage filling refers to providing hydrogen to the unmanned aerial vehicle hydrogen storage bottle group by two vehicle-mounted high-pressure hydrogen storage bottles. It should be noted that the pressure difference between the unmanned aerial vehicle hydrogen storage bottle and the vehicle-mounted high-pressure hydrogen storage bottle is used to fill hydrogen during the hydrogen filling process of the hydrogen fuel cell unmanned aerial vehicle. If the pressure of a single vehicle-mounted high-pressure hydrogen storage bottle cannot meet the demand for filling hydrogen to the unmanned aerial vehicle hydrogen storage bottle group, two-stage filling mode can be used. By flexibly changing the pressure hydrogen injection mode according to the pressure of the vehicle-mounted high-pressure hydrogen storage bottle, the efficiency and safety of the filling process are ensured, thereby improving the hydrogen filling efficiency.

[0062] Specifically, it is detected whether the current vehicle-mounted high-pressure hydrogen storage bottle meets a preset pressure condition, and the pressure hydrogen injection mode is adjusted according to the pressure of the vehicle-mounted high-pressure hydrogen storage bottle. The above-mentioned preset pressure condition can be set to be that the pressure of the vehicle-mounted high-pressure hydrogen storage bottle is greater than or equal to (P+20 MPa). If the vehicle-mounted high-pressure hydrogen storage bottle does not meet the preset pressure condition, the current vehicle-mounted high-pressure hydrogen storage bottle is determined to be a first target vehicle-mounted high-pressure hydrogen storage bottle, and another vehicle-mounted high-pressure hydrogen storage bottle adjacent to the first target vehicle-mounted high-pressure hydrogen storage bottle is determined to be a second target vehicle-mounted high-pressure hydrogen storage bottle, and two-stage filling is performed by the first target vehicle-mounted high-pressure hydrogen storage bottle and the second target vehicle-mounted high-pressure hydrogen storage bottle. If the vehicle-mounted high-pressure hydrogen storage bottle meets the preset pressure condition, the current vehicle-mounted high-pressure hydrogen storage bottle is used to fill hydrogen to the unmanned aerial vehicle hydrogen storage bottle group, that is, direct filling is used.

[0063] In one embodiment, the above-mentioned two-stage filling mode also needs to judge the pressure condition of each target vehicle-mounted high-pressure hydrogen storage bottle, and the target vehicle-mounted high-pressure hydrogen storage bottle for hydrogen injection is selected according to different pressure conditions. According to the pressure demand of the unmanned aerial vehicle hydrogen storage bottle and the hydrogen injection sequence, the first target vehicle-mounted high-pressure hydrogen storage bottle is provided with a first preset pressure condition, and the second target vehicle-mounted high-pressure hydrogen storage bottle is provided with a second preset pressure condition. Exemplarily, the first preset pressure condition can be that the pressure of the first target vehicle-mounted high-pressure hydrogen storage bottle is greater than or equal to P / 3, and the second preset pressure condition can be that the pressure of the second target vehicle-mounted high-pressure hydrogen storage bottle is greater than or equal to (P+10 MPa). Specifically, the following four cases are included:

[0064] Case one: in the case where it is determined that the first target vehicle-mounted high-pressure hydrogen storage bottle meets the first preset pressure condition and it is determined that the second target vehicle-mounted high-pressure hydrogen storage bottle meets the second preset pressure condition, the first target vehicle-mounted high-pressure hydrogen storage bottle is used to perform one-stage hydrogen injection operation on the unmanned aerial vehicle hydrogen storage bottle group, and after the one-stage hydrogen injection operation is completed, the second target vehicle-mounted high-pressure hydrogen storage bottle is used to perform two-stage hydrogen injection operation on the unmanned aerial vehicle.

[0065] Case two: in the case where the first target vehicle-mounted high-pressure hydrogen storage bottle meets the first preset pressure condition, but the second target vehicle-mounted high-pressure hydrogen storage bottle does not meet the second preset pressure condition, the second target vehicle-mounted high-pressure hydrogen storage bottle is actively pressurized by the first target vehicle-mounted high-pressure hydrogen storage bottle.

[0066] Case three: in the case where the first target vehicle-mounted high-pressure hydrogen storage bottle does not meet the first preset pressure condition, it is necessary to determine whether the second target vehicle-mounted high-pressure hydrogen storage bottle meets the preset pressure condition, and in the case where the second target vehicle-mounted high-pressure hydrogen storage bottle meets the preset pressure condition, the second target vehicle-mounted high-pressure hydrogen storage bottle is directly used to inject hydrogen into the unmanned aerial vehicle.

[0067] Case four: in the case where the first target vehicle-mounted high-pressure hydrogen storage bottle does not meet the first preset pressure condition, it is necessary to determine whether the second target vehicle-mounted high-pressure hydrogen storage bottle meets the preset pressure condition, and in the case where the second target vehicle-mounted high-pressure hydrogen storage bottle does not meet the preset pressure condition, the second target vehicle-mounted high-pressure hydrogen storage bottle is actively pressurized by the first target vehicle-mounted high-pressure hydrogen storage bottle.
