[0032] The specific embodiments of the present invention will be further described and illustrated below with reference to the accompanying drawings.

[0033] like Figures 1 to 4 As shown, the on-site trace emergency rapid detection method based on drones, the specific steps of the rapid detection method are as follows:

[0034] Step 1: Flight of the UAV platform: The UAV carries the trace detection device and communicates with the ground control center through a communication system. The ground control center controls the flight of the UAV platform and flies it to the designated location. The UAV platform is equipped with a dual-rotor UAV to quickly arrive at the scene: The UAV responds quickly and traverses complex environments to reach areas that are difficult for people to access;

[0035] Step 2: Collecting trace samples: The drone brings the paint test stick to the designated testing area. The test paper on the drone platform and the test paper on the paint test stick come into contact with and sample the test object, completing trace sampling. The drone, carrying the trace detection device, flies over the area. The test paper on the drone platform and the test paper on the coating test stick quickly capture possible hazardous samples.

[0036] Step 3: Sample recovery: The drone brings back the paint detection stick, removes the sampling test paper on the drone and the paint detection stick, and completes the sample recovery; immediate return and analysis: After the sampling is completed, the drone quickly returns to the safe area and transmits the gas sample adsorbed in the paint to the portable analysis equipment at the ground control station for rapid analysis.

[0037] Step 4: Rapid detection and analysis of samples: Use the carried analytical equipment to quickly analyze and detect trace components of the sample captured on the paint detection stick to obtain the analysis results;

[0038] Step 5: Data Analysis and Decision Support: Based on the analysis results from Step 4, the sample composition and concentration are determined. This analysis provides a scientific basis for decision-making and the corresponding decision-making content. The analysis results provide a scientific basis for firefighters' bomb disposal decisions, such as determining the type of explosive, assessing the hazard level, and formulating protective measures.

[0039] The analytical detection method used in the step 4 is mass spectrometry (MS), which measures the mass and intensity of ions and analyzes the composition and structure to obtain trace component analysis in the sample. Trace coating detection sticks / trace detection test paper serve as core collection tools and can effectively capture key trace information such as harmful gases in the air, tiny residues on the surface of the ground and objects. Environmental samples are obtained by regular cruising in three-dimensional space, touching obstacles and wiping, and then returning to the on-site nuclear, biological and chemical detection formation to analyze the samples, so as to quickly learn about the dangerous sources of unknown dangerous environments, and provide timely and accurate data support for emergency management departments, thereby greatly shortening decision-making time.

[0040] The principle of trace detection technology is shown in the following table:

[0041]

[0042] Table 1: Principles of trace detection technology

[0043] During the application process, the trace detection technology carried by drones can be promoted in the fields of efficient environmental testing, precision agricultural management, disaster emergency response, etc.

[0044] 1. Efficient environmental monitoring: Drones can quickly cover large areas. Drones can be equipped with equipment such as spectrometers and chemical sensors through flexible suspension modules to detect trace pollutants in the atmosphere and water bodies in real time, such as PM2.5, VOCs, heavy metals, etc., providing timely and accurate data support for environmental protection.

[0045] 2. Precision agricultural management: In the agricultural field, drones can be equipped with multispectral cameras and soil nutrient sensors through flexible suspension modules to conduct low-altitude scanning of farmland, accurately obtain crop growth status and soil nutrient information, guide farmers to carry out precise fertilization and irrigation, and improve agricultural production efficiency and crop quality.

[0046] 3. Disaster emergency response: After a natural disaster occurs, drones can quickly enter the disaster area and carry trace detection equipment through flexible suspension modules to detect toxic and harmful gases in the air, pollutants in water, etc., providing safety information to rescue personnel, ensuring the smooth progress of rescue operations, and reducing the impact of disasters on the environment and human health.

[0047] 4. Advantages Summary: Rapid response and efficient coverage. Drones' high maneuverability and wide-area coverage make trace detection more rapid and comprehensive. They reduce risk of personnel entering dangerous or hard-to-reach areas, ensuring their safety. Accurate and reliable data, combined with advanced trace detection technology, provides highly precise results, providing a scientific basis for decision-making.

[0048] like Figures 2 to 4 As shown, a drone device comprises: a drone platform 1, a trace detection device 2 and a drone 3, wherein the drone platform 1 is provided with the drone 3 having a double rotor, and the drone 3 is provided with a double rotor wing, and the double rotor wing is arranged and distributed in a honeycomb shape. The trace detection device comprises a paint detection stick 21 and a trace detection test paper 22, wherein the trace detection test paper 22 is attached to the surface of the paint detection stick 21 and the drone platform 1, and the paint detection stick 21 is connected to the drone platform 1 in a movable suspension. The upper end of the paint detection stick 21 is connected to a spring body 4, and the paint detection stick 21 is suspended on the drone platform 1 by the spring body 4. The lower end of the paint detection stick 21 is provided with a spherical detection surface 211, and the surface of the paint detection stick 21 is attached with a trace detection test paper 22.

[0049] By improving the structure of the UAV platform 1, a multi-directional dual-rotor UAV platform mechanism is designed, which can improve the maneuverability, stability and flight accuracy of the UAV equipment, and improve the safety of the platform, and can be applied to operations in different field environments; at the same time, by combining the UAV platform 1 with the paint detection stick 21, it is possible to effectively cope with detection under complex environmental conditions, and solve the problem that traditional detection methods are difficult to implement or prone to errors in complex environments.

[0050] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial improvement of the present invention using this concept should be considered an infringement of the protection scope of the present invention.
