A person of ordinary skill in the art will understand the specific meanings of these terms in the context of this application based on specific circumstances.

[0049] like Figure 1-5 As shown, a pollen monitor is provided, which includes: a sample collecting mechanism 1 for collecting pollen samples and a sample processing mechanism 2 for processing the pollen samples collected by the sample collecting mechanism 1.

[0050] The sample collection mechanism 1 includes a sampling mechanism housing 11, a sensor 12 disposed in the sampling mechanism housing 11 for collecting external environmental information, an openable and closable sampling head 13, a driving component 14 for driving the sampling head 13 to open and close, and a control unit 15 for issuing a working instruction to the driving component 14 according to the external environmental information collected by the sensor 12.

[0051] The sample processing mechanism 2 includes a sample processing mechanism housing 21 , a material belt 22 for fixing pollen samples, a conveying component 23 for conveying the material belt 22 , and a monitoring component 24 for monitoring the pollen samples fixed on the material belt 22 .

[0052] In the above embodiment, sensor 12 acquires external environmental information. After receiving this environmental information, control unit 15 determines whether to collect pollen samples and whether the collection environment is suitable. If pollen sample collection is not necessary, control unit 15 issues a command to drive drive assembly 14 to close sampling head 13. If pollen sample collection is necessary, control unit 15 issues a command to drive drive assembly 14 to open sampling head 13 and collect pollen samples. External environmental information can include various types of information, such as temperature and humidity.

[0053] In some embodiments, the sensor 12 includes a laser raindrop sensor for detecting the size and frequency of raindrops. A titanium alloy baffle for shielding the sampling port is provided on the sampling head 13. The laser raindrop sensor identifies the characteristics of heavy rain. After the characteristics of heavy rain reach a threshold, the titanium alloy baffle is driven to close by a solenoid valve. Heavy rain characteristics include rainfall and / or raindrop density. The rainfall threshold is 15 mm / h, and the raindrop density threshold is 2000 drops / ㎡·s. After the rainfall is ≥15 mm / h or / and the raindrop density is >2000 drops / ㎡·s, the control unit 15 issues a work instruction to drive the drive component 14. The closing speed of the titanium alloy baffle is less than 0.8s, and a silicone sealing ring and a nano-hydrophobic coating are provided between the titanium alloy baffle and the sampling port of the sampling head 13 for sealing.

[0054] In some embodiments, the sampling head 13 is made of a corrosion-resistant lightweight material. The sampling head 13 is connected to the drive assembly 23 via a rotating shaft. The surface of the rotating shaft is coated with a hard anodized layer. The thickness of the hard anodized layer is ≥10μm. Corrosion resistance refers to passing the ISO 9227 neutral salt spray test for ≥500h with a surface corrosion area rate of ≤5%. Lightweight material refers to a density of ≤3.0g / cm 3 The material has a tensile strength of ≥150Mpa. The hard anodized layer on the shaft surface is in accordance with MIL-A-8625F standard.

[0055] In some embodiments, the driving component 14 is a micro motor or a pneumatic device.

[0056] In some embodiments, the sampling mechanism housing 11 is made of a weather-resistant material. Weather resistance refers to materials with high UV resistance and good thermal deformation stability. UV resistance is defined as a color difference ΔE ≤ 2.0 (referring to CIE Lab* standards) and a surface chalking grade ≤ 1 (GB / T 1766) after 1000 hours of ISO 4892-2:2013 xenon lamp aging test. Thermal deformation stability is defined as a dimensional change of ≤ 0.5% after 100 cycles of temperature cycling from -40°C to 85°C (IEC 60068-2-14 test Nb).

[0057] In some embodiments, the material strip has a three-layer structure, wherein the surface layer is a protective film, the middle layer is a release film, and the bottom layer is a substrate coated with a medical-grade adhesive. The release film is provided with a sampling hole 221 and an air flow hole 222. The sampling hole 221 is used to expose the substrate as a sampling area. There are multiple air flow holes 222, and the multiple air flow holes 222 are evenly distributed around the sampling hole 221. The sampling hole 221 can be set to different shapes as needed, such as circular, rectangular, elliptical, etc. The air flow hole 222 is used for the airflow formed by the negative pressure of the sampling head 13 during the sampling process. The surface protective film is a transparent biaxially oriented polypropylene (BOPP) film with a thickness of 25±5μm (in accordance with ASTM D2103), and the surface is corona treated to ≥38dyn / cm; the release film is a polyester (PET) film with a thickness of 50±10μm (refer to FINAT FTM 3 standard) and a peel force of 0.05-0.15N / 25mm; the bottom substrate is a pressure-sensitive adhesive-coated polyester (PET) film with a thickness of 100±20μm (refer to FINAT FTM 3 standard). In some embodiments, the transmission assembly 23 includes: a discharge wheel 231 for storing unused material tape 22; a separator 232 for separating the protective film in the unused material tape 22 to obtain a sampling tape with the sampling area exposed to the outside; a waste film winding wheel 233 for winding up the separated protective film as waste film; a laminator 234 for re-pasting the protective film on the sampled sampling tape; a receiving wheel 235 for collecting the material tape on which the pollen sample has been fixed; a motor 236 for controlling the operation of the discharge wheel 231, the separator 232, the waste film winding wheel 233, the laminator 234 and the receiving wheel 235, as well as the anti-sway transmission shaft 237, for ensuring the stability of the material tape 22 when it is transmitted between the various structures of the transmission assembly 23.

[0058] In the above embodiment, the various structures of the transmission assembly 23 adopt a modular design, and each structure is connected through precision machinery to form a transmission operation chain. The discharge wheel 231 serves as the working starting point of the entire transmission assembly 23. It seamlessly connects with the anti-sway transmission shaft 237 through a magnetic coupling with an air gap of 0.5mm, avoiding mechanical contact contamination; the anti-sway transmission shaft 237 adopts a dual-bearing four-point support structure with a parallelism within 0.01mm / m. Its surface is designed as a spiral-straight composite groove: the end of the spiral section (45° bevel, pitch 2.5mm) is connected to an adjustable connecting rod through a quick-release universal joint (axial tolerance ±0.05mm). The connecting rod has a dual-mode adjustment function: coarse adjustment uses a ratchet locking structure (±5mm adjustment range), and fine adjustment uses a piezoelectric micro-displacer to achieve 0.001mm level accuracy. A PTFE-impregnated copper sleeve is built into the connecting rod hinge to ensure a 5000-hour maintenance-free cycle. In the subsequent process, the separator 232 accurately peels off the protective film, and the waste film is recovered by the waste film reel 233. The exposed release film is transmitted to the lower side of the sampling head 13 to receive the sample collected by the sampling head 13. The monitoring component 24 monitors the sample on the release film. Then, the cold-pressed composite roller (surface coated with diamond-like film, friction coefficient μ < 0.05) on the laminator 234 is pressed at 15N / cm 2 A new film is applied under the given conditions, and the film is finally rewound by the rewinding wheel 235 under constant tension (tension fluctuation ≤ ±0.1N). In some embodiments, the monitoring component 24 includes: a camera 241 for capturing an image of the material strip 22 fixed with the pollen sample; and a laser coder 242 for printing a mark on the material strip 22.

[0059] In the above embodiment, the monitoring component 24 is equipped with a three-axis precision slide with a verticality of ≤0.005°, which drives the camera 241 to perform macro scanning (Z-axis focusing accuracy ±5μm). The detection data triggers the laser coder 242 (20W fiber laser, dynamic focus compensation delay ≤2ms) in real time to complete the marking, and the marking includes a time mark and a position mark. The laser marker 242 engraves a millisecond-level timestamp (±0.1ms) and coordinate code next to the sample, and the camera 241 synchronously captures high-definition images and realizes mark-image alignment through a calibration algorithm. The spatiotemporal data is encrypted by SHA-256 and automatically bound to the image to meet the traceability requirements of the entire environmental monitoring process. The monitoring component obtains the "time-location-device ID-environmental parameters" multi-dimensional code to generate a unique identification code, which can provide corresponding reliable evidence for manual re-inspection, so that the monitoring results can be traced.

[0060] In some embodiments, a pollen monitoring method is provided, wherein the method uses the pollen monitor as described in any one of the above items, including:

[0061] The sensor 12 collects environmental information and sends the collected environmental information to the control unit 15;

[0062] After receiving the environmental information, the control unit 15 issues a work instruction to the driving component 14 according to the environmental information;

[0063] The driving component 14 controls the sampling head 13 which can be opened and closed to perform sampling according to the received working instructions;

[0064] The unwinding wheel 231 rotates under the drive of the motor 236, driving the unused material strip 22 to move;

[0065] When the material belt 22 moves to the separator 232, the separator 232 separates the protective film on the material belt 22 to obtain a sampling belt with the sampling area exposed to the outside, and discards the separated protective film. The waste film reel 233 recycles the discarded protective film.

[0066] The sampling head 13 places the collected pollen sample on the sampling area;

[0067] The monitoring component 24 monitors the pollen samples collected in the sampling area;

[0068] The film covering device 234 re-applies the protective film on the sampled sampling tape;

[0070] Print time and position marks near the sampling area;

[0071] The camera 241 is used to capture images of the sampling area, time mark and position mark, and obtain a multi-dimensional code of "time-position-equipment ID-environmental parameters" to generate a unique identification code.
