[0028] As Figures 1 - 3 shown, a drone flight recorder according to an embodiment of the first aspect of the present utility model includes an assembly housing 100, a barometric pressure detection module 310, a processing module 320, a data transmission module 330, and a valve assembly 400. The assembly housing 100 has an inner cavity. The assembly housing 100 is provided with an assembly structure for mounting on a drone. The barometric pressure detection module 310 is disposed in the assembly housing 100 and is located in the inner cavity. The barometric pressure detection module 310 is used to detect barometric pressure information. The processing module 320 is disposed in the assembly housing 100 and is located in the inner cavity. The processing module 320 is connected to the barometric pressure detection module 310. The data transmission module 330 is disposed in the assembly housing 100 and is located in the inner cavity. The processing module 320 is connected to the data transmission module 330 to send the barometric pressure information through the data transmission module 330. The assembly housing 100 is provided with a ventilation port communicating with the inner cavity. The valve assembly 400 is disposed on the assembly housing 100 and is located at the ventilation port. The valve assembly 400 is used to allow gas to pass through the ventilation port while isolating water and particles.

[0029] Among them, the assembly housing 100 can be made of an alloy or resin material with good anti-corrosion performance. The assembly housing 100 can be in the shape of a cuboid, a cylinder, etc., and has a small volume, which is convenient to be arranged on the unmanned aerial vehicle and minimizes the impact on the flight of the unmanned aerial vehicle.

[0030] The data transmission module 330 can adopt mobile communication chips such as 3G / 4G / 5G, and can wirelessly communicate with the monitoring center. Specifically, the data transmission module 330 can adopt a 4G LTE wireless module to provide high-speed data connection and communication capabilities through the built-in antenna or external antenna. The supported frequency bands are: LTE-TDD: B34 / B38 / B39 / B40 / B41; LTE-FDD: B1 / B3 / B5 / B8, etc. The processing module 320 can be selected from an MCU or a CPU and its attached circuits.

[0031] In some embodiments of the present utility model, as Figure 3 shown, a Bluetooth module 340 and a touch switch 350 are further arranged in the assembly housing 100, and the processing module 320 is respectively connected to the Bluetooth module 340 and the touch switch 350.

[0032] The touch switch 350 can be a capacitive induction switch, which is arranged in the assembly housing 100 without the need to open holes on the assembly housing 100 for installation, ensuring the waterproof and dustproof performance of the assembly housing 100. The user can touch the induction position of the touch switch 350, and the touch switch 350 forms a trigger signal to control the processing module 320 to start. The Bluetooth module 340 can be interconnected with the controller of the unmanned aerial vehicle to obtain the identity information of the unmanned aerial vehicle, so as to pair and upload the detection data together, and can also receive control instructions to control the recorder.

[0033] The unmanned aerial vehicle flight recorder of the present utility model is installed on the unmanned aerial vehicle through an assembly structure without modifying the structure of the unmanned aerial vehicle itself. When the unmanned aerial vehicle flies at a high altitude, the air valve assembly 400 can allow the gas in the environment to enter the inner cavity through the ventilation port, but isolates the entry of water and particles. Thus, the air pressure detection module 310 detects the gas pressure in the inner cavity, which is equivalent to detecting the gas pressure in the environment. The processing module 320 sends the air pressure information through the data transmission module 330, and the monitoring center can monitor the unmanned aerial vehicle. This design is suitable for high-altitude detection, ensuring the stability and durability of the detection.

[0034] In some embodiments of the present utility model, as Figure 1 shown, the air valve assembly 400 includes a valve plate 420. The valve plate 420 is arranged on the assembly housing 100 and covers the ventilation port. A plurality of micropores are arranged on the valve plate 420, and the micropores allow gas to pass through the ventilation port while isolating water or particles.

[0035] Specifically, the valve plate 420 can be a film made of a polymer material. The pore diameter of the micropores is less than 0.2 nm, which can effectively isolate the water mist and dust in the high-altitude environment. In some embodiments of the present invention, a baffle 410 is further provided in front of the valve plate 420 on the assembly housing 100. The baffle 410 is connected to the assembly housing 100 through a bracket. There is a ventilation gap between the baffle 410 and the valve plate 420. The baffle 410 can first block the water mist and dust in the external environment, reducing the filtration pressure of the valve plate 420.

[0036] In some embodiments of the present invention, as Figure 1 shown, the assembly housing 100 includes a base 110, a face cover 120, and an elastic gasket 130. The base 110 and the face cover 120 are connected to enclose the inner cavity. The elastic gasket 130 is located between the connection positions of the base 110 and the face cover 120. The elastic gasket 130 is in contact with the base 110 and the face cover 120 respectively.

[0037] The base 110 and the face cover 120 can be connected by snaps or screws. As Figure 1 shown, the base 110 is provided with a receiving groove having an opening. The base 110 is provided with a plurality of first screw holes at the edge of the opening. The face cover 120 is provided with second screw holes corresponding to the first screw holes. Screws are inserted through the first screw holes and the second screw holes, so that the base 110 and the face cover 120 are connected. When the base 110 and the face cover 120 are connected, the base 110 and the face cover 120 will respectively squeeze the elastic gasket 130, which can make the inner cavity relatively sealed and reduce the probability of water and dust entering the inner cavity from the connection gap.

[0038] In some embodiments of the present invention, the UAV flight recorder further includes a satellite positioning module 360. The satellite positioning module 360 is used to detect position information. The processing module 320 is connected to the satellite positioning module 360. The processing module 320 sends the position information through the data transmission module 330.

[0039] The satellite positioning module 360 can adopt an ultra-low power consumption and high-precision GNSS positioning module, which supports the reception of data from four global navigation microsystems, namely Beidou, GPS, GLONASS, and Galileox, as well as single-mode, dual-mode, and multi-mode working modes.

[0040] Specifically, the air pressure detection module 310 obtains altitude information based on the measured atmospheric pressure. The satellite positioning module 360 can also measure altitude information. After the altitude information from the two sources is fused in the processing module 320, the calculated altitude is used as the final measured altitude and sent to the monitoring center through the data transmission module. Additionally, based on the obtained air pressure information and position information of each drone, the monitoring center can determine the flight altitude and flight trajectory of each drone.

[0041] In some embodiments of the present invention, the drone flight recorder further includes a temperature detection module 370. The temperature detection module 370 is used to detect temperature information, and the processing module 320 is connected to the temperature detection module 370.

[0042] The temperature detection module 370 can be selected from conventional temperature sensors. Since the low temperature at high altitudes affects the accuracy of the air pressure detection module 310 in detecting gas pressure, it is necessary to use the temperature detection module 370 to detect the ambient temperature, and then correct the air pressure information detected by the air pressure detection module 310 according to the temperature information to improve the accuracy of air pressure detection.

[0043] In some embodiments of the present invention, the air pressure detection module 310 is a capacitive air pressure sensor, which has high precision and maintains high precision in detecting air pressure under temperature changes.

[0044] In some embodiments of the present invention, as Figure 2 shown, an energy storage module 610 and a wireless charging coil 620 are provided inside the assembly housing 100. The wireless charging coil 620 is connected to the energy storage module 610, and the energy storage module 610 is connected to the processing module 320 to supply power to the processing module 320.

[0045] The energy storage module 610 can be selected from storage batteries such as lithium batteries or supercapacitor elements. Additionally, in this design, wireless charging is adopted, and there is no need to set a port for wired charging on the assembly housing 100, which further improves the waterproof and dustproof performance and also improves the charging convenience.

[0046] Specifically, a rectifying circuit, a switching circuit, etc. are also provided on the circuit board inside the assembly housing 100. The wireless charging coil 620 can be coupled with the discharging coil of an external charging power source. The rectifying circuit rectifies the alternating current generated by the wireless charging coil 620, and then adjusts the magnitude of the current and voltage through the switching circuit, and finally charges the energy storage module 610.

[0047] In some embodiments of the present utility model, the assembly structure includes an adhesive layer (not shown in the figure) provided on the outer surface of the assembly housing 100. The assembly housing 100 can be adhered to the drone through the adhesive layer, which is convenient for connection.

[0048] In some embodiments of the present utility model, as Figure 1 shown, the assembly structure includes a frame body 510 provided on the assembly housing 100. An installation opening 520 is provided on the frame body 510. The installation opening 520 is used for threading a binding strap, and the binding strap can be bound to the frame body 510.

[0049] Both ends of the frame body 510 can be connected to the assembly housing 100. An installation opening 520 is formed between the middle of both ends of the frame body 510 and the outer wall surface of the assembly housing 100. The binding strap can be threaded through the installation opening 520 and then bound to the frame body 510. The binding strap can be bound to the drone, so as to arrange the assembly housing 100 on the drone.

[0050] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
