Description

Technical Field

[0001] This invention belongs to the field of unmanned aerial vehicle (UAV) meteorological data acquisition technology, specifically relating to a high-precision airborne meteorological monitoring integrated device for UAVs. Background Technology

[0002] Meteorology has a significant impact on human life and agricultural production. Meteorological stations are the main devices for monitoring meteorological conditions. Currently, meteorological data acquisition mainly relies on ground-based fixed meteorological observation and detection equipment or unpowered airborne balloons. These can only monitor some meteorological data at the ground and near specific altitudes, and cannot monitor meteorological data at a specific altitude or area in real time and flexibly. Although manned fixed-wing aircraft can collect upper-air meteorological data, they have disadvantages such as high cost, short collection time, difficulty in flight path planning, limited data types, and higher risk to crew members in severe weather. Currently, when drones are used for meteorological monitoring, they are usually applied in two ways: one is to carry a single-function meteorological sensor (such as a temperature probe), which can only acquire limited parameters and lacks comprehensive data; the other is to simply bundle multiple independent commercial micro sensors (such as temperature, relative humidity, and barometric pressure sensors) and install them on the drone's fuselage or landing gear. These sensors are usually from different manufacturers and work independently. They transmit data to the flight control computer or ground station separately via their respective data cables or wireless modules, and then the software performs data aggregation and simple processing. This combination method only achieves physical concentration of equipment, rather than true system integration.

[0003] Currently, existing airborne meteorological monitoring integrated devices have each data acquisition module operating independently, connected to the main unit via wires. This not only results in a disorganized and inconvenient setup but also compromises flight safety, leading to inconvenience in use. Firstly, low integration impacts flight performance. Multiple independent devices, their connecting cables, and power supplies result in a large overall payload size, weight, and poor aerodynamic shape, significantly increasing the UAV's power consumption, shortening its effective flight time, and potentially affecting flight stability and controllability. Secondly, the multi-channel acquisition and transmission leads to poor data synchronization and fusion. Independent acquisition and transmission by each sensor result in asynchronous timestamps and inconsistent sampling frequencies, making it difficult to accurately match multi-element meteorological data on a spatiotemporal reference. This hinders subsequent data fusion analysis and the construction of refined meteorological models, affecting monitoring accuracy. Thirdly, the installation layout is unscientific, leading to significant mutual interference. Simple, bundled installations fail to adequately consider the impact of electromagnetic interference and thermal interference between sensors, as well as the UAV's own components (such as propeller airflow and motor heat) on measurement accuracy. For example, if the wind direction and speed meter is installed in the propeller turbulence area, the measurement value will be severely distorted; the heat generated by electronic components will affect the readings of nearby temperature sensors; fourth, the system reliability and maintainability are affected, as exposed cables and multiple plug-ins are prone to loosening and damage in complex flight environments, resulting in a high failure rate, and the dispersed modules also make daily calibration, maintenance, and upgrades extremely inconvenient; fifth, the functional expandability is weak, as the existing loose structure makes it difficult to easily integrate new detection modules (such as visibility meters and particulate matter sensors), and the system upgrade and customization capabilities are insufficient. Summary of the Invention

[0004] (a) Technical problems to be solved The technical problem this invention aims to solve is: how to overcome the shortcomings of existing technologies and provide a high-precision airborne meteorological monitoring device for unmanned aerial vehicles (UAVs); how to achieve deep integration of six meteorological elements (temperature, relative humidity, visibility, air pressure, wind direction, and wind speed) detection equipment through a highly integrated and modular design, providing a guarantee for synchronous data acquisition and real-time fusion processing; optimizing sensor layout to minimize interference from the aircraft; and ultimately achieving high precision, high reliability, low load impact, and good scalability for meteorological monitoring on UAV platforms. This high-precision airborne meteorological monitoring device can be mounted on UAVs and can provide timely and effective decision support for industries such as ecological environmental protection, wind power new energy, and aviation airports, helping them significantly improve work efficiency and reduce safety risks and costs. It supports simultaneous monitoring of six parameters in a single mission and can accurately collect six meteorological data: temperature, humidity, air pressure, wind speed, wind direction, and visibility.

[0005] (II) Technical Solution To address the aforementioned technical problems, this invention provides a high-precision airborne meteorological monitoring integrated device for unmanned aerial vehicles (UAVs), such as... Figure 1-5As shown, the high-precision airborne meteorological monitoring integrated device includes: a housing 1; The upper surface of the housing 1 is provided with a temperature and humidity sensor 2 and an ultrasonic anemometer 3. The front side of the housing 1 is provided with a status indicator light 7 and a visibility meter 8. The rear side of the housing 1 is provided with an SD card slot 4, a heat dissipation hole 5 and a data interface 6. The bottom of the housing 1 is connected and fixed to the drone through a quick-release structure 9.

[0006] The quick-installation structure 9 includes an upper bracket 10 that is installed in conjunction with the bottom of the housing 1, and a lower bracket 14 that is installed in conjunction with the upper surface of the drone.

[0007] The upper bracket 10 is fixedly connected to the bottom of the housing 1 at its four corners via a first connecting device; The upper support 10 is configured as a rectangular frame, with an L-shaped first folded edge 11 at the bottom edge of each of its two long sides. Each of the two first folded edges 11 forms a slot 12 with the corresponding long side, and the openings of the two slots 12 are arranged opposite each other. A protrusion 13 is provided at the bottom of one of the two short sides of the upper support 10.

[0008] The lower support 14 is provided with lugs 15 at each of its four corners, and the lugs 15 are fixedly connected to the drone through a second connecting device. The lower support 14 is also configured as a rectangular frame, and its two long sides are provided with second folded edges 16 corresponding to the first folded edge 11 on the upper surface; in the process of connecting the high-precision airborne meteorological monitoring integrated device with the UAV, the second folded edge 16 is configured to be pulled and connected to the slot 12. A protective shell 17 is provided on one of the two short sides of the lower support 14. The protective shell 17 includes an integrally formed horizontal plate and a vertical plate. The upper surface of the horizontal plate is connected to a limit block 21 via a rotating shaft 20. The side wall of the limit block 21 is connected to the vertical plate of the protective shell 17 via a spring 19. An operating rod 18 extending to the outside of the protective shell 17 is provided on one end of the limit rod 21. The other end of the limiting block 21 corresponds to the protrusion 13 during the connection between the high-precision airborne meteorological monitoring integrated device and the UAV, and the other end of the limiting block 21 is set as a pointed cone composed of an inclined surface facing the protrusion 13 and a plane facing away from the protrusion 13.

[0009] When the high-precision airborne meteorological monitoring integrated device is connected and installed with the UAV, the four lugs 15 at the four corners of the lower bracket 14 are aligned with the four holes on the top of the UAV and fixed by the second connecting device. The four holes at the four corners of the upper bracket 10 are aligned with the four holes at the bottom of the housing 1 and fixed by the first connecting device; The two slots 12 of the upper bracket 10 are aligned with the second folded edge 16 of the lower bracket 14. The lower bracket 14 is pushed to slide into the upper bracket 10. When the pointed cone of the limiting block 21 just contacts the protrusion 13, since the contact surface of the limiting block 21 facing the protrusion 13 is set as an inclined surface, the limiting block 21 continues to move forward while rotating around the pivot 20 under the condition that the pushing force overcomes the elastic force of the spring 19, until the limiting block 21 completely passes around the protrusion 13. At this time, under the action of the spring 19's rebound force, the limiting block 21 rotates and abuts against the protrusion 13 from the plane facing away from the protrusion 13, realizing reverse restriction and disengagement. At this time, a clear locking sound can be felt, which means that the installation is secure.

[0010] When the high-precision airborne meteorological monitoring integrated device and the UAV are disconnected after the connection is completed, the limit block 21 is rotated by the operating lever 18 to make way for the protrusion 13, and the lower bracket 14 can slide away from the upper bracket 10.

[0011] Among them, the ultrasonic anemometer 3 is a high-precision ultrasonic wind speed and direction data acquisition sensor that uses the phase acoustic wave principle and can measure a maximum wind speed of 50m / s. The temperature and humidity sensor 2 is a high-precision environmental temperature and humidity measurement sensor used to collect temperature and humidity data in the environment. The humidity accuracy is up to ±1.5%RH and the temperature accuracy is up to ±0.1°C. The sensor shell is made of water-based reflective heat-insulating coating, which is not easily affected by the heat generated by the data processing part, so as to reduce the measurement temperature and humidity errors caused by direct sunlight.

[0012] The visibility meter 8 is an automatic and continuous sensor for monitoring atmospheric visibility. Visibility is calculated based on the forward scattering principle by actively emitting an infrared beam and measuring the scattering of the beam by atmospheric particles in the sampling area.

[0013] The data interface 6 establishes communication with the drone and provides power via a data cable, and is plugged into the drone's E-Port interface to provide 24V power. The SD card slot 4 comes standard with a 32GB storage card, capable of continuously storing >4000 hours of monitoring data; The heat dissipation hole 5 is a heat dissipation window for the monitoring integrated device, which uses air self-heating; The status indicator lights 7 are divided into sensor compartment indicator light, satellite positioning indicator light, PSDK indicator light, storage card indicator light, network communication indicator light, and main program indicator light. The sensor compartment indicator light indicates that data has been received from the sensor compartment. A solid satellite positioning indicator light indicates that the satellite signal is good and positioning is possible. A solid PSDK indicator light indicates that communication with the drone via PSDK has been successful. A solid storage card indicator light indicates that data is being written. A solid network communication indicator light indicates that data is being transmitted normally. A solid main program indicator light indicates that the internal main program has started normally. A flashing satellite positioning indicator light indicates that the satellite signal is poor and positioning is not possible. A flashing PSDK indicator light indicates that the PSDK connection has not been successful. A flashing storage card indicator light indicates that the device is warming up / the satellite signal is poor / the storage card is full (please copy the data). A non-lit network communication indicator light indicates that no data card is inserted / the data card has no data. A solid-on network communication indicator light followed by a short-off signal indicates that the network is being searched for. A short-on, solid-off network communication indicator light indicates that there is no data transmission.

[0015] (III) Beneficial Effects Compared with the prior art, the technical solution of the present invention has the following technical features: First, the invention features a highly integrated and modular design. It physically integrates various heterogeneous sensors, a unified power supply, a main control unit, and a data processing unit into a single, aerodynamically optimized housing, forming a standard "plug-and-play" payload module, which greatly simplifies the integration difficulty of the UAV.

[0016] Secondly, the internal structural design (such as heat insulation and compartmentation) actively suppresses electromagnetic, thermal, and vibration interference generated by the module itself.

[0017] Third, it features standardized high-speed data interfaces and protocols, employing a single, high-speed, and reliable data bus for external output. The standardized interfaces greatly simplify the electrical and logical connections with UAV platforms.

[0018] Fourth, the various data acquisition modules are integrated into a unified entity, connected to the aircraft via only one data transmission line, which improves work efficiency and flight safety.

[0019] Technical effects: This product can be mounted on drones. Through highly integrated modules and a quick-installation structure—specifically, the cooperation between the upper and lower brackets—it allows for rapid installation and disassembly from the drone, greatly improving its practicality and flexibility. It can acquire accurate six meteorological parameters in real time, providing timely and effective decision support for industries such as ecological environmental protection, wind power, and aviation airports, helping them significantly improve work efficiency and reduce safety risks and costs. It also supports simultaneous monitoring of all six parameters in a single mission, accurately collecting six meteorological data points: temperature, humidity, air pressure, wind speed, wind direction, and visibility. Real-time data display and subsequent data table generation are supported to meet diverse application needs.

[0020] First, it significantly improves monitoring accuracy and data quality. The optimized layout and active interference suppression measures, combined with the field's commonly used synchronous acquisition and data fusion algorithms, reduce measurement errors at the source and ensure the inherent consistency and high reliability of multi-element data.

[0021] Secondly, the payload performance of the drone has been greatly optimized. The integrated design reduces aerodynamic drag, the lightweight structure reduces ineffective load, and one module replaces multiple scattered devices, making the drone have a longer endurance and more stable flight.

[0022] Third, it enhances system reliability and maintainability. The internal wiring is simplified, and the external interface is single and robust, reducing the failure rate. The entire module can be quickly disassembled, calibrated, and upgraded, making maintenance convenient.

[0023] Fourth, it achieves true plug-and-play functionality and excellent scalability. Standardized mechanical and electrical interfaces enable it to quickly adapt to various drone models. The modular design facilitates the integration of new sensors (such as pollutant gas monitoring sensors) by replacing or adding internal boards in the future, and the technology upgrade path is clear.

[0024] Fifth, it reduces system complexity and cost. For drone platforms, there is no need to configure interfaces and processing units for each sensor separately, which simplifies the overall integration and application costs. Attached Figure Description
