In this embodiment, the remote control device can be installed in the base station cavity, or installed separately outside the base station and connected to the base station by wire.
[0033] Furthermore, the parking platform 200 includes a parking area 210, a guide portion 220 adjacent to the parking area 210, and a positioning point 230 arranged in the parking area 210; wherein, the guide portion 220 surrounds the parking area 210 to limit the size of the parking area 210, and the guide portion 220 includes a guide surface 221 facing the parking area 210. When the unmanned aerial vehicle 20 needs to land on the parking platform 200, the remote control device sends the position information of the unmanned aerial vehicle base station 10 to the unmanned aerial vehicle 20, so as to enable the unmanned aerial vehicle 20 to fly above the parking platform 200 according to the position information, and land on the guide portion 220, slide along the guide surface 221 of the guide portion 220 to the parking area 210, and complete the positioning at the positioning point 230. In some embodiments, the parking platform 200 may include two or more parking areas 210, the guide portion 220 limits the size of the overall parking area 210, isolation members (not shown in the figure) are arranged between adjacent parking areas 210, and each parking area 210 is provided with the positioning point 230.
[0034] Furthermore, a charging position 231 is provided on the positioning point 230, and the charging position 231 is used to electrically contact the tripod of the unmanned aerial vehicle 20 so as to electrically connect the unmanned aerial vehicle base station 10 with the unmanned aerial vehicle 20, and pairs of metal contacts are set on the charging position 231, wherein the paired metal contacts are respectively connected to different electrodes of the charging power supply.

[0036] Optionally, the metal contacts set on the charging position 231 described in the aforementioned embodiment may include charging metal contacts and data transmission metal contacts. While the unmanned aerial vehicle 20 is charged through the charging metal contacts, it can also realize wired communication with the base station through the data transmission metal contacts to perform different types of data interaction, such as upgrading the flight control system of the unmanned aerial vehicle 20.
[0037] Optionally, a limiting portion 232 is further provided on the aforementioned positioning point 230, and the limiting portion 232 can cooperate with the bottom of the tripod of the unmanned aerial vehicle 20 to limit the movement of the unmanned aerial vehicle 20 on the plane. For example, the limiting portion 232 is a limiting groove, and the tripod of the unmanned aerial vehicle 20 is provided with a protrusion. When the unmanned aerial vehicle 20 lands on the guide portion 220 and slides along the guide surface 221 to the parking area 210, the charging contact of the unmanned aerial vehicle 20 is positioned at the positioning point 230, and the protrusion at the bottom of the tripod of the unmanned aerial vehicle 20 is just positioned in the limiting groove, so that the unmanned aerial vehicle 20 The traveler 20 cannot translate or rotate within the plane where the parking area 210 is located; because the unmanned aerial vehicle 20 can slide down to the parking area 210 under the action of the guide portion 220 to complete precise positioning, even when the metal contact area on the charging position 231 is small, the tripod of the unmanned aerial vehicle 20 can accurately contact the metal contact on the charging position 231, thereby realizing the electrical connection between the unmanned aerial vehicle 20 and the unmanned aerial vehicle base station 10, and then realizing the charging of the unmanned aerial vehicle 20; in a specific embodiment, the charging position 231 is located in the limiting portion 232, and can also be located on one side of the limiting portion 232.

[0040] Further, the guide portion 220 may include a plurality of guide surfaces 221 facing the parking area 210, and each guide surface 221 may be a plane or a curved surface inclined relative to the parking area 210, so as to form a depression above the parking area 210, and the depression is used to accommodate the UAV 20. The shape and size of the parking area 210 are defined by the guide portion 220 surrounding the parking area 210, for example, the guide portion 220 of the parking area 210 includes four first guide surfaces 2210 of the same shape and size and four second guide surfaces 2211 of the same shape and size, the four first guide surfaces 2210 are connected to the corresponding edges of the parking area 210, and each of the four second guide surfaces 2211 is connected between two corresponding adjacent first guide surfaces 2210, so as to define a rectangular area, which is the parking area 210. Generally, the shape and size of the parking area 210 match the shape and size of the tripod of the UAV 20. In some embodiments, the guide portion 220 may be a guide plate or a guide stage.
[0041] Re-read Figure 2 The UAV base station 10 further includes a protective component 300 mounted on the housing 100. Specifically, the protective component 300 is located above the parking platform 200. The protective component 300 cooperates with the parking area 210 and the guide portion 220 to form a receiving chamber for the UAV 20. The protective component 300 is used to protect the parking platform 200 and the UAV 20 that lands on the parking platform 200. In this embodiment, the protective component 300 can achieve dustproof, waterproof, high temperature and sun protection effects, forming a safe storage environment that effectively protects the UAV 20 when operating outdoors for a long time.
[0042] Further, see Figure 4 The protection assembly 300 includes a driving member 310 and a protection door 320. The driving member 310 drives the protection door 320 to open or close relative to the housing 100. The protection door 320 can be a single-open or double-open flat door, or a box-shaped or hemispherical special-shaped door. The special-shaped door can also be set to a single-open or double-open form. As an optional solution, a transparent window can be set on the protection door 320. In some other optional solutions, the protection assembly 300 also includes a sealing ring set on the protection door 320, and the sealing ring can be a rubber ring.
[0043] In some embodiments, the driving member 310 may be a lifting cylinder, and a piston rod of the lifting cylinder is fixedly connected to the protective door 320 to drive the protective door 320 to move in a vertical direction to complete the opening and closing of the protective door 320.
[0044] In some other embodiments, the protection assembly 300 further includes a connection assembly 330 , and the connection assembly 330 connects the protection door 320 and the housing 100 .
[0045] As an alternative, refer to Figure 4 The connecting assembly 330 is an external hinge structure, specifically including a first connecting portion 331, a second connecting portion 332 and a rotating shaft 333, wherein the first connecting portion 331 and the second connecting portion 332 are respectively connected to the outer surface of the protective door 320 and the shell 100, and the rotating shaft 333 is connected to the driving member 310, and the first connecting portion 331 and the second connecting portion 332 are rotatably connected through the rotating shaft 333; the connecting surface of the first connecting portion 331 and the second connecting portion 332 adopts a large-area connecting surface, and the first connecting portion 331 and the second connecting portion 332 are respectively fixed on the outer surface of the protective door 320 and the shell 100 by screws or rivets, and the rotating shaft 333 is fixedly connected to the first connecting portion 331, and the rotating shaft 333 is installed on the bearing seat provided on the second connecting portion 332 through a bearing, and the rotating shaft 333 is driven to rotate by the driving member 310, thereby driving the first connecting portion 331 and the protective door 320 to move as a whole. , realizing the opening and closing of the protective door 320; in this embodiment, the protective component 300 includes a plurality of connecting components 330, the rotating shafts 333 of the plurality of connecting components 330 are coaxial, and the rotating shaft 333 of one of the connecting components 330 is connected to the driving member 310. In this embodiment, the connecting component 330 is adjustable to ensure the coaxiality of the rotating shafts of the plurality of connecting components 330; because the connecting component 330 adopts an external hinge structure, it can be unfolded at a larger angle, so that the opening and closing range of the protective door 320 is larger, and at the same time, an external hinge mechanism is adopted, when the protective door 320 is closed, the protective door 320 and the shell 100 are completely closed to form a relatively sealed unmanned aerial vehicle 20 storage chamber, which is beneficial to dustproof and waterproof, etc. At the same time, the first connecting part 331 and the second connecting part 332 adopt a large-area connecting surface, which can increase the stability of the protective door 320 and the ability of side wind resistance and impact resistance, and ensure that the protective door 320 can be safely opened and closed in windy weather.
[0046] As an optional solution, the connecting assembly 330 includes a guide rail (not shown in the figure) and a sliding seat (not shown in the figure), the guide rail is fixedly connected to the protective door 320 and one of the shells 100, the sliding seat is fixedly connected to the protective door 320 and the other of the shells 100, and the driving member 310 is connected to the sliding seat.
[0047] Furthermore, in another embodiment, the guide portion 220 described in the aforementioned embodiment includes a plurality of guide surfaces 221 facing the parking area 210, and a first ventilation portion 2212 is provided on part or all of the guide surfaces 221. The unmanned aerial vehicle 20 may cause the battery to heat up due to charging or the fuselage to heat up due to operation at high temperature. In these cases, when the unmanned aerial vehicle 20 lands in the parking area 210 of the parking platform 200, air can be supplied through the first ventilation portion 2212 provided on the guide surface 221 to cool down the fuselage or battery of the unmanned aerial vehicle 20; in other embodiments, a guide fan (not shown in the figure) is provided on the side of the guide portion 220 away from the parking area 210, and the size of the blades of the guide fan is adapted to the size of the first ventilation portion 2212 provided on the guide surface 221; as an optional embodiment, the first ventilation portion 2212 is a mesh vent or a grid vent.
[0048] Further, the parking area 210 is provided with a second ventilation part 211. As an optional embodiment, the second ventilation part 211 provided in the parking area 210 includes a plurality of orderly arranged through holes, and these through holes can be arranged around the positioning point 230. Of course, the second ventilation part 211 provided in the parking area 210 can also be a mesh vent or a grid vent. Optionally, a guide fan can also be installed at the back of the parking area 210.
[0049] Furthermore, the UAV base station 10 is correspondingly provided with a temperature regulating device (not shown in the figure), which may be a fan or an air conditioner, and the temperature regulating device may regulate the temperature inside the base station. When the UAV 20 lands on the parking platform 200 and the protective door 320 of the protective assembly 300 arranged above the parking platform 200 is closed, the above-mentioned base station inner cavity, the first ventilation part 2212 and the second ventilation part 211, and the receiving cavity together constitute a circulating air flow channel. Under the action of the guide fan, the cold air blown out by the temperature regulating device of the UAV base station 10 flows in the air flow channel, and the cooling air blown out by the temperature regulating device of the UAV base station 10 flows in the air flow channel. Figure 1 The black hollow arrows in the figure indicate the direction of air flow. Specifically, under the action of the guide fan, the cold air output by the temperature adjustment device enters the receiving chamber from the inner cavity of the base station through the first ventilation part 2212. The hot air after cooling the unmanned aerial vehicle 20 then returns from the receiving chamber through the second ventilation part 211 to the inner cavity of the base station to be cooled by the temperature adjustment device. This cycle can effectively reduce the body or battery temperature of the unmanned aerial vehicle 20. Of course, in a low-temperature environment, the temperature adjustment device of the unmanned aerial vehicle base station 10 can also blow warm air to flow in the air flow channel to increase the body temperature of the unmanned aerial vehicle 20.
[0050] In other embodiments, the remote control device includes a radio frequency identification antenna (not shown in the figure), which is arranged below the positioning point 230 and is used to authenticate the identity of the unmanned aerial vehicle 20 that needs to land.
[0051] Furthermore, the unmanned aerial vehicle base station 10 is also provided with an environmental monitoring device (not shown in the figure), and the environmental data information collected by the environmental monitoring device is transmitted to the background server through the remote control device, wherein the environmental data information includes temperature information, humidity information, light intensity information, rainfall information, wind speed information, etc. The flight of the unmanned aerial vehicle 20 needs to meet certain flight conditions. For example, the temperature range of the outdoor working of the unmanned aerial vehicle 20 is -20℃ to 45℃, and the wind speed range of the outdoor working is 0m / s to 12m / s. When the temperature or wind speed exceeds the working range, or in rainy weather, it is not conducive to the flight of the unmanned aerial vehicle 20. Therefore, by collecting environmental data information and judging whether environmental data information such as temperature information, humidity information, light intensity information, rainfall information, wind speed information, etc. are within the normal range, if any one item exceeds the normal range, it is considered that the environmental data information is abnormal. At this time, it is necessary to control the unmanned aerial vehicle 20 to return or stop the unmanned aerial vehicle 20 from taking off as soon as possible to ensure that the unmanned aerial vehicle 20 performs flight missions under suitable environmental conditions and to ensure the safety and reliability of the unmanned aerial vehicle 20 when it is stored or working outdoors for a long time.
[0052] Furthermore, the UAV base station 10 is also provided with a display device (not shown in the figure) for displaying the status information of the UAV base station 10, the environmental data information collected by the environmental monitoring device, and the status information of the UAV 20, which can make it more convenient for ground staff to maintain the equipment and instruments of the base station. In other embodiments, for the convenience of maintenance, an operating door 110 is provided on the housing 100 for debugging the components inside the housing 100.
[0053] Furthermore, the UAV base station 10 is also provided with a backup power supply (not shown in the figure). When the external power supply of the UAV base station 10 is unstable or interrupted, the UAV base station 10 automatically switches to the backup power supply to ensure that the UAV 20 can continue to establish a connection with the UAV base station 10, automatically continue to perform operating operations and return safely, and prevent accidents or operation interruptions caused by the loss of remote control information by the UAV 20 due to unstable or interrupted power supply of the UAV base station 10; Optionally, the backup power supply is a battery, which can be charged by a solar panel or by a power supply outside the UAV base station 10; In some embodiments, when the UAV base station 10 switches to the backup power supply and the power of the backup power supply drops to a certain range, the UAV base station 10 will send a return command to the UAV 20 to ensure that the UAV 20 returns safely and lands on the parking platform 200 of the UAV base station 10 before the backup power supply is insufficient.
[0054] Compared with the existing UAV base station 10, the UAV base station 10 provided by the above embodiment has at least the following advantages:
[0055] (1) The parking platform 200 of the UAV base station 10 has a simple structure and can realize accurate landing and positioning of the UAV 20 on the parking platform 200 without the need for a high-precision mechanical arm or a positioning and navigation module. On the one hand, the equipment cost and complexity of the parking platform 200 are reduced, and on the other hand, the accuracy requirements for the navigation and positioning equipment of the UAV 20 are reduced. The platform has strong versatility and a wider range of applications.
[0056] (2) When the UAV 20 lands on the parking platform 200, the UAV 20 can be automatically charged on the parking platform 200. Due to the high-precision positioning, the area of the metal contact of the charging position 231 can be very small, which can effectively avoid the safety hazards caused by large-area exposed metal contacts;
[0057] (3) When the unmanned aerial vehicle 20 is automatically charged, the battery of the unmanned aerial vehicle 20 can be effectively cooled to improve safety;
[0058] (4) When the UAV 20 lands on the parking platform 200 for storage or charging, the UAV 20 is protected by the protective component 300, which can effectively prevent water, dust, high temperature and exposure, etc., to ensure the safety and reliability of the UAV 20 when it is stored outdoors for a long time;
[0059] (5) By collecting environmental data information, it is possible to ensure that the UAV 20 automatically performs operations under suitable environmental conditions, thereby ensuring the safety of the UAV 20.
[0060] (6) By providing a backup battery for the base station, the base station can avoid losing contact with the UAV 20 due to unstable power supply or power outage, thereby ensuring that the UAV 20 can continue to perform operations and return safely.
[0061] Based on the UAV base station 10 provided in the above embodiment, the present invention also provides a landing system for an UAV.

In this embodiment, the unmanned aerial vehicle 20 is equipped with an RTK (Real-time kinematic) positioning module, and the unmanned aerial vehicle 20 receives and processes the location information through the RTK positioning module to obtain accurate positioning information.
[0062] Furthermore, the parking platform 200 includes a parking area 210, a guide portion 220 adjacent to the parking area 210, and a positioning point 230 arranged in the parking area 210; wherein, the guide portion 220 surrounds the parking area 210 to limit the size of the parking area 210, and the guide portion 220 includes a guide surface 221 facing the parking area 210. When the unmanned aerial vehicle 20 needs to land on the parking platform 200, the remote control device sends the position information of the unmanned aerial vehicle base station 10 to the unmanned aerial vehicle 20, so as to enable the unmanned aerial vehicle 20 to fly above the parking platform 200 according to the position information, and land on the guide portion 220, slide along the guide surface 221 of the guide portion 220 to the parking area 210, and complete the positioning at the positioning point 230. When the UAV 20 flies above the parking platform 200 according to the position information, the projection of the tripod of the UAV 20 on the parking platform 200 is located in the area where the guide portion 220 is located and / or in the parking area 210 .

After the UAV 20 is positioned at the positioning point 230 , the charging position 231 is in electrical contact with the tripod of the UAV 20 , thereby realizing the electrical connection between the UAV base station 10 and the UAV 20 .
[0065] In some embodiments, a pair of metal contacts is disposed on the charging position 231 , wherein the pair of metal contacts is respectively connected to different electrodes of a charging power source.

The shape and size of the parking area 210 are defined by the guide portion 220 surrounding the parking area 210, for example, the guide portion 220 of the parking area 210 includes four first guide surfaces 2210 of the same shape and size and four second guide surfaces 2211 of the same shape and size, the four first guide surfaces 2210 are connected to the corresponding edges of the parking area 210, and each of the four second guide surfaces 2211 is connected between two corresponding adjacent first guide surfaces 2210, thereby defining a rectangular area, which is the parking area 210. Generally, the shape and size of the parking area 210 match the shape and size of the tripod of the UAV 20. In some embodiments, the guide portion 220 may be a guide plate or a guide stage.
[0072] Furthermore, the UAV base station 10 further includes a protective component 300, which is used to protect the parking platform 200 and the UAV 20 landed on the parking platform 200. The protective component 300 is located above the parking platform 200, and the protective component 300 cooperates with the parking platform 200 to form a receiving cavity for the UAV 20. The protective component 300 is used to protect the parking platform 200 and the UAV 20 landed on the parking platform 200. In this embodiment, the protective component 300 can achieve dustproof, waterproof, high temperature and sun protection effects, and form a safe storage environment that effectively protects the UAV 20 during long-term outdoor operations.
[0073] In some embodiments, the protection assembly 300 includes a driving member 310 and a protection door 320. The protection assembly 300 opens the protection door 320 through the driving member 310 before the UAV 20 lands on the parking platform 200, and closes the protection door 320 through the driving member 310 after the UAV 20 lands on the parking platform 200. The protection door 320 can be a single-open or double-open flat door, or a box-shaped or hemispherical special-shaped door, which can also be set to a single-open or double-open form; as an optional solution, a transparent window can be set on the protection door 320. In other optional solutions, the protection assembly 300 also includes a sealing ring set on the protection door 320, and the sealing ring can be a rubber ring.
[0074] In some embodiments, the driving member 310 may be a lifting cylinder, and a piston rod of the lifting cylinder is fixedly connected to the protective door 320 to drive the protective door 320 to move in a vertical direction to complete the opening and closing of the protective door 320.
[0075] In some other embodiments, the protection assembly 300 further includes a connection assembly 330 , and the connection assembly 330 connects the protection door 320 and the housing 100 .
[0076] As an alternative, refer to Figure 4 The connecting assembly 330 is an external hinge structure, specifically including a first connecting portion 331, a second connecting portion 332 and a rotating shaft 333, wherein the first connecting portion 331 and the second connecting portion 332 are respectively connected to the outer surface of the protective door 320 and the shell 100, and the rotating shaft 333 is connected to the driving member 310, and the first connecting portion 331 and the second connecting portion 332 are rotatably connected through the rotating shaft 333; the connecting surface of the first connecting portion 331 and the second connecting portion 332 adopts a large-area connecting surface, and the first connecting portion 331 and the second connecting portion 332 are respectively fixed on the outer surface of the protective door 320 and the shell 100 by screws or rivets, and the rotating shaft 333 is fixedly connected to the first connecting portion 331, and the rotating shaft 333 is installed on the bearing seat provided on the second connecting portion 332 through a bearing, and the rotating shaft 333 is driven to rotate by the driving member 310, thereby driving the first connecting portion 331 and the protective door 320 to move as a whole. , realizing the opening and closing of the protective door 320; in this embodiment, the protective component 300 includes a plurality of connecting components 330, the rotating shafts 333 of the plurality of connecting components 330 are coaxial, and the rotating shaft 333 of one of the connecting components 330 is connected to the driving member 310. In this embodiment, the connecting component 330 is adjustable to ensure the coaxiality of the rotating shafts of the plurality of connecting components 330; because the connecting component 330 adopts an external hinge structure, it can be unfolded at a larger angle, so that the opening and closing range of the protective door 320 is larger, and at the same time, an external hinge mechanism is adopted, when the protective door 320 is closed, the protective door 320 and the shell 100 are completely closed to form a relatively sealed unmanned aerial vehicle 20 storage chamber, which is beneficial to dustproof and waterproof, etc. At the same time, the first connecting part 331 and the second connecting part 332 adopt a large-area connecting surface, which can increase the stability of the protective door 320 and the ability of side wind resistance and impact resistance, and ensure that the protective door 320 can be safely opened and closed in windy weather.
[0077] As an optional solution, the connecting assembly 330 includes a guide rail (not shown in the figure) and a sliding seat (not shown in the figure), the guide rail is fixedly connected to the protective door 320 and one of the shells 100, the sliding seat is fixedly connected to the protective door 320 and the other of the shells 100, and the driving member 310 is connected to the sliding seat.
[0078] Furthermore, the UAV base station 10 is equipped with a radio frequency identification antenna, which is arranged below the positioning point 230. Before the UAV 20 lands on the parking platform 200, the UAV base station 10 authenticates the identity of the UAV 20 through the radio frequency identification antenna.
[0079] Furthermore, the unmanned aerial vehicle base station 10 is also provided with an environmental monitoring device, and the environmental data information collected by the environmental monitoring device is transmitted to the background server through the remote control device, and when the background server determines that the environmental data information is abnormal, the unmanned aerial vehicle base station 10 sends a return command to the unmanned aerial vehicle 20 through the remote control device. Specifically, the environmental data information collected by the environmental monitoring device is transmitted to the background server through the remote control device, wherein the environmental data information includes temperature information, humidity information, light intensity information, rainfall information, wind speed information, etc. The flight of the unmanned aerial vehicle 20 needs to meet certain flight conditions. For example, the temperature range of the outdoor working of the unmanned aerial vehicle 20 is -20℃ to 45℃, and the wind speed range of the outdoor working is 0m / s to 12m / s. When the temperature or wind speed exceeds the working range, or in rainy weather, it is not conducive to the flight of the unmanned aerial vehicle 20. Therefore, by collecting environmental data information and judging whether environmental data information such as temperature information, humidity information, light intensity information, rainfall information, wind speed information, etc. are within the normal range, if any one item exceeds the normal range, it is considered that the environmental data information is abnormal. At this time, it is necessary to control the unmanned aerial vehicle 20 to return or stop the unmanned aerial vehicle 20 from taking off as soon as possible to ensure that the unmanned aerial vehicle 20 performs flight missions under suitable environmental conditions and to ensure the safety and reliability of the unmanned aerial vehicle 20 when it is stored or working outdoors for a long time.
[0080] Furthermore, the UAV base station 10 is also provided with a temperature regulating device. After the UAV 20 lands on the parking platform 200, the UAV base station 10 starts the temperature regulating device to regulate the temperature inside the base station. Optionally, the guide portion 220 of the unmanned aerial vehicle base station 10 includes a plurality of guide surfaces 221 facing the parking area 210, and a first ventilation portion 2212 is provided on part or all of the guide surfaces 221. The unmanned aerial vehicle 20 may heat up its battery due to charging or its fuselage may heat up due to operation at high temperature. In these cases, when the unmanned aerial vehicle 20 lands in the parking area 210 of the parking platform 200, air can be supplied through the first ventilation portion 2212 provided on the guide surface 221 to cool down the fuselage or battery of the unmanned aerial vehicle 20; in other embodiments, a guide fan (not shown in the figure) is provided on the side of the guide portion 220 facing away from the parking area 210, and the size of the blades of the guide fan is adapted to the size of the first ventilation portion 2212 provided on the guide surface 221; as an optional embodiment, the first ventilation portion 2212 is a mesh vent or a grid vent.
[0081] Further, the parking area 210 is provided with a second ventilation part 211. As an optional embodiment, the second ventilation part 211 provided in the parking area 210 includes a plurality of orderly arranged through holes, and these through holes can be arranged around the positioning point 230. Of course, the second ventilation part 211 provided in the parking area 210 can also be a mesh vent or a grid vent. Optionally, a guide fan can also be installed at the back of the parking area 210.
[0082] When the UAV 20 lands on the parking platform 200 and the protective door 320 of the protective assembly 300 disposed above the parking platform 200 is closed, the base station inner cavity, the first ventilation part 2212, the second ventilation part 211, and the receiving cavity together form a circulating air flow channel. Under the action of the guide fan, the cold air blown out by the temperature adjustment device of the UAV base station 10 flows in the air flow channel. Figure 1 The black hollow arrows in the figure indicate the direction of air flow. Specifically, under the action of the guide fan, the cold air output by the temperature adjustment device enters the receiving chamber from the inner cavity of the base station through the first ventilation part 2212. The hot air after cooling the unmanned aerial vehicle 20 then returns from the receiving chamber through the second ventilation part 211 to the inner cavity of the base station to be cooled by the temperature adjustment device. This cycle can effectively reduce the body or battery temperature of the unmanned aerial vehicle 20. Of course, in a low-temperature environment, the temperature adjustment device of the unmanned aerial vehicle base station 10 can also blow warm air to flow in the air flow channel to increase the body temperature of the unmanned aerial vehicle 20.
