Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicles (UAVs), and more specifically to a meteorological monitoring system based on UAVs. Background Technology

[0002] The UAV meteorological monitoring system is designed and developed to handle various meteorological elements such as visibility, atmospheric temperature, relative humidity, atmospheric pressure, wind speed, and wind direction. It can collect, analyze, process, and store data of different elements in real time, and then upload the data according to data protocols. Simultaneously, it can remotely monitor the data of the entire system in real time, making it representative of the diverse needs in rapid deployment of meteorological monitoring and meteorological disaster early warning and detection research.

[0003] Currently, the construction of UAV meteorological systems mainly adopts the scheme of integrating meteorological sensors for measurement. Due to limitations such as sensor accuracy, flight attitude, and environmental conditions, there may be problems such as unstable data quality, insufficient reliability, and great dependence on weather and environmental conditions. Therefore, it is necessary to design a meteorological monitoring system based on UAVs that can provide more accurate test data compared to the scheme of integrating meteorological sensors for measurement, and can be used by a variety of UAVs. Utility Model Content

[0004] The purpose of this invention is to provide a meteorological monitoring system based on unmanned aerial vehicles (UAVs).

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A drone-based weather monitoring system is provided, including a visibility sensor module, a mounting base, and a power and communication port. The visibility sensor module is connected to the drone's mechanical structure via the mounting base. A microcontroller is mounted on the structural components of the visibility sensor module, and the visibility sensor module is connected to the microcontroller via a power supply line. The power and communication port is integrated into the microcontroller and is connected to the drone via power and communication lines. The power and communication port is located on the side that is in contact with the drone. The visibility sensor module is equipped with a transmitting module and a receiving module, and the visibility sensor module is connected to the microcontroller's electrical signals by transmitting and receiving analog signals through the transmitting and receiving modules.

[0007] Furthermore, the transmitting and receiving modules on the visibility sensor module are tilted upwards by 5 to 10 degrees relative to the horizontal plane.

[0008] Furthermore, the bottom of the mounting base is provided with cross-shaped feet, each end of which is provided with a screw, and the drone is provided with screw holes for connecting to the screws.

[0009] Furthermore, an ultrasonic wind speed and direction sensor is fixedly installed on the top of the visibility sensor module, and the ultrasonic wind speed and direction sensor is connected to the microcontroller via serial communication.

[0010] Furthermore, a temperature, humidity, and pressure sensor module is fixedly installed at the bottom of the visibility sensor module.

[0011] The beneficial effects of this invention are as follows: This invention, through an ultrasonic wind speed and direction sensor, a visibility sensor module, and a temperature, humidity, and pressure sensor module, can accurately measure elements such as visibility, atmospheric temperature, relative humidity, atmospheric pressure, wind speed, and wind direction. The detection equipment transmits the data back to the drone's remote control via the drone's communication link. This drone meteorological monitoring system enables rapid deployment of meteorological monitoring, meteorological disaster early warning detection data measurement, collection, and transmission. Compared to solutions integrating measurement with dedicated meteorological sensors, its test data is more accurate.

[0012] Furthermore, this component can adapt to various measurement environments, avoid tangling between the wiring harness and the drone, and greatly shorten the design cycle through integrated design. Parallel product development and testing can also significantly shorten the design cycle. Utilizing this mature modular device can greatly shorten the R&D cycle, procurement cycle, and manufacturing cycle, thereby accelerating the time to market.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent.

[0021] Reference Figures 1 to 3 The UAV-based weather monitoring system shown includes a visibility sensor module 2, a mounting base 4, and a power supply and communication port 5. The visibility sensor module 2 is connected to the mechanical structure of the UAV via the mounting base 4. A microcontroller is mounted on the structure of the visibility sensor module 2, and the visibility sensor module 2 is connected to the microcontroller via a power supply line. The power supply and communication port 5 is integrated into the microcontroller and is connected to the UAV via power supply and communication lines. The power supply and communication port 5 is located on the side that is in contact with the UAV, so that the wiring harness is not exposed during wiring, avoiding the UAV from getting tangled in the wiring harness during flight. The wiring harness also has a reverse connection protection function. Furthermore, through the structure of the mounting base 4, the wiring harness of the visibility sensor module 2 can be hidden inside the mounting base 4, achieving the effect of internal wiring. The visibility sensor module 2 is equipped with a transmitting module and a receiving module. The visibility sensor module 2 is connected to the microcontroller via transmitting and receiving analog signals. The visibility sensor module 2's structural features make it well-suited as the foundation of the entire system. It transmits visibility signals to the microcontroller, which then forwards the signals to the drone. Furthermore, the design of the mounting base 4 solves the problems of exposed wiring and installation, allowing this drone-based weather monitoring system to be mounted on drones of any structure.

[0022] Mounting base 4, which connects to the mechanical structure of the drone, is designed with a base that is compatible with the drone and a section for easy cable routing to avoid exposed cables. The sensors are concentrated on the upper side, separating the sensors from the drone, thus preventing the eddies caused by the drone propellers from affecting the visibility sensor module 2.

[0023] The mounting base 4 connects to the DJI M350's dedicated E-Port interface on one end and to the main control microcontroller on the other, transmitting data via serial communication. This system is compatible with various drones, especially the DJI M350-RTK.

[0024] The transmitting and receiving modules on the visibility sensor module 2 are tilted upwards by 5 to 10 degrees relative to the horizontal plane. This upward tilt is designed to avoid measuring infrared signals from drones or propellers.

[0025] The bottom of the mounting base 4 is equipped with cross-shaped feet, each end of which is fitted with a screw. The drone has screw holes for connecting to the screws. The cross-shaped feet and screws allow the drone-based weather monitoring system to be detached from the drone.

[0026] An ultrasonic wind speed and direction sensor 1 is fixedly mounted on the top of the visibility sensor module 2. The ultrasonic wind speed and direction sensor 1 is connected to the microcontroller via serial communication. Due to its wind measurement requirements, the ultrasonic wind speed and direction sensor 1 needs to be placed on the top of the visibility sensor module 2 to achieve the best measurement results and to avoid the wind generated by the drone propellers affecting the measurement results.

[0027] A temperature, humidity and pressure sensor module 3 is fixedly installed at the bottom of the visibility sensor module 2. The temperature, humidity and pressure sensor module 3 is placed at the bottom of the visibility sensor module 2 to avoid interference from the airflow above and below the drone on its measurement results.

[0028] The ultrasonic wind speed and direction sensor 1, visibility sensor module 2, temperature, humidity and pressure sensor module 3, mounting base 4, and power supply and communication port 5 are installed using threads and quick-drying adhesive through reserved mounting positions. Internally, a motherboard, acquisition board, transmitter board, receiver board, and temperature, humidity and pressure measurement board are installed, enabling power supply to the sensors and data acquisition, processing, and transmission. This UAV meteorological monitoring system can measure visibility, atmospheric temperature, relative humidity, atmospheric pressure, wind speed, and wind direction.

[0029] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
