The clamping assembly 43 is provided on the mounting frame 41, and is used to clamp the insert block 42 or release the insert block 42. After the insert block 42 is removed from the mounting frame 41, the staff can install the laser radar 5 on the insert block 42, and then insert the insert block 42 with the laser radar 5 back into the slot 411, so as to facilitate the installation or removal of the laser radar 5. The insert block 42 can be clamped and fixed by the clamping assembly 43 to prevent the insert block 42 from shaking and affecting the use of the laser radar 5. Among them, the light sensor 6 and the temperature and humidity sensor 7 can be installed on the insert block 42 corresponding to the hoisting mechanism 4. Optionally, the lifting mechanism 4 also includes a telescopic connecting column 44, one end of the telescopic connecting column 44 is detachably connected to the mounting frame 41, and the other end of the telescopic connecting column 44 is detachably connected to the UAV body 1, and the length of the telescopic connecting column 44 is adjustable, so that by adjusting the length of the telescopic connecting column 44, the position of the mounting frame 41 relative to the UAV body 1 can be adjusted, thereby facilitating information collection by the information collection UAV.

[0042] Among them, the clamping assembly 43 includes a slider 431, a bidirectional threaded rod 432 and a clamping block 433. The bidirectional threaded rod 432 is rotatably arranged on the slider 431. The clamping block 433 includes two, and the two clamping blocks 433 are respectively threadedly connected to the two ends of the bidirectional threaded rod 432. When the bidirectional threaded rod 432 rotates relative to the slider 431, the two clamping blocks 433 will move closer to or away from each other, thereby clamping or loosening the plug block 42. At the same time, the mounting frame 41 is provided with a lifting slot 412 connected to the slot 411. The lifting slot 412 is located above the slot 411.

When the positioning sleeve 435 is disengaged from the positioning groove 414, the clamping assembly 43 can be normally lifted and lowered on the mounting frame 41. When the positioning sleeve 435 is inserted into the positioning groove 414, the clamping assembly 43 is fixed to the mounting frame 41, so as to facilitate the staff to disassemble or install the plug 42.

[0044] like Figure 1 and Figure 2 As shown, the visible light camera 2, the multi-spectral camera 3 and the hoisting mechanism 4 are all arranged below the drone body 1, so that the visible light camera 2, the multi-spectral camera 3 and the equipment on the hoisting mechanism 4 will not be blocked by the drone body 1, wherein the hoisting mechanism 4 is located in the middle position of the drone body 1, and the visible light camera 2 and the multi-spectral camera 3 are respectively located on the opposite sides of the hoisting mechanism 4, so that the center of gravity of the information collection drone approaches the middle position, and the stability of the information collection drone when moving is improved.

[0045] Embodiment 2

[0046] This embodiment also provides a method for using an information collection drone, using the information collection drone of the first embodiment, such as Figure 6 As shown, the method for using the information collection drone includes the following steps:

[0047] The visible light camera 2, the multi-spectral camera 3 and the laser radar 5 are installed on the drone body 1, and the parameters of the drone body 1, the visible light camera 2, the multi-spectral camera 3 and the laser radar 5 are adjusted and powered on;

[0048] The drone body 1 is equipped with a visible light camera 2, a multi-spectral camera 3 and a laser radar 5 to collect information on tobacco, and the collected data is transmitted to a ground control station for data storage and data analysis.

[0049] The method for using the information collection drone first adjusts the parameters and performs power-on tests on the drone body 1, the visible light camera 2, the multispectral camera 3, the laser radar 5 and related equipment, so as to realize the relevant preparation and inspection of the equipment in the advance planning of the task, and ensure that the information collection drone works normally. In the process of formally using the information collection drone, the data in the tobacco field is obtained through the visible light camera 2, the multispectral camera 3, the laser radar 5 and related equipment, and the data is stored and analyzed through the ground control station, so as to meet the needs of refined management of tobacco planting in precision agriculture.

[0050] Specifically, in the advance planning stage of the task, through field surveys or obtaining high-precision maps, the area where tobacco field data collection is required is clearly defined, and the boundaries and special terrain locations are marked.

[0051] When setting the parameters of the drone body 1, the flight altitude, speed, route overlap rate and other parameters are set according to the size, shape and terrain of the target area, combined with the performance parameters of the drone body 1. The flight altitude is generally set at 50 meters to 100 meters, which can ensure the acquisition of clear data and the safe flight of the information collection drone. Among them, the route overlap rate is set to 70% to 80% to ensure the integrity and accuracy of the data.

[0052] When setting the parameters of the visible light camera 2, the multispectral camera 3, the lidar 5, the light sensor 6 and the temperature and humidity sensor 7, according to the tobacco growth characteristics and collection requirements, adjust the shooting interval of the high-definition visible light camera 2, the band combination of the multispectral camera 3, the scanning frequency of the lidar 5, and the sampling frequency of the temperature and humidity sensor 7 and the light sensor 6. For example, the high-definition visible light camera 2 can be set to take an image every 5 seconds, and the multispectral camera 3 selects a specific band combination for data collection according to different growth stages.

[0053] By powering on the drone body 1, visible light camera 2, multi-spectral camera 3, lidar 5, light sensor 6 and temperature and humidity sensor 7, ensure that each device is working properly, check whether the data transmission lines between the devices are firmly connected to avoid looseness or poor contact, and conduct a comprehensive inspection of the drone's battery power, motor performance, flight control system, communication link, etc. to ensure that the drone is in good flight condition. At the same time, check whether the drone's GPS positioning system is accurate and calibrate the compass to avoid positioning deviation during flight.

[0054] During the information collection phase, the staff sends a take-off command through the ground control station, and the information collection drone flies according to the preset route and parameters. During the flight, the ground control station monitors the flight status of the information collection drone in real time, including location, altitude, speed, power and other information to ensure flight safety. Each sensor collects data according to the set parameters, and all collected data is transmitted to the ground control station in real time through the data transmission link and initially stored.

[0055] In the data analysis stage, the data stored on the information collection drone is transmitted to the computer of the data processing center by wired or wireless means to ensure that the data is complete and not lost. The data of the light sensor 6 is used to perform radiation correction on the multispectral data to remove the influence of the change of ambient light intensity on the spectral data. At the same time, the high-definition visible light image and multispectral image are pre-processed by denoising, geometric correction and other operations to improve the image quality. Professional image recognition and data analysis software are used to analyze the pre-processed data. The pest and disease situation, growth height, leaf area index and other parameters of the tobacco plants are identified through image recognition technology; combined with the laser radar 5 data, the spatial distribution of the tobacco plants is analyzed to see whether it is reasonable and whether there are areas with over-dense or over-sparse planting; multispectral data is used to evaluate the nutritional status and physiological state of the tobacco plants, providing a decision-making basis for precision agricultural management.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
