Description

Technical Field

[0001] The invention relates to the technical field of environmental monitoring, and in particular to an online detection system for atmospheric pollen. Background Art

[0002] Pollen is one of the main components of bioaerosols in the atmospheric environment and one of the main pathogenic factors of allergic rhinitis, allergic conjunctivitis, asthma, urticaria, allergic dermatitis and other diseases. Most pollen has a diameter of about 20 to 50 microns.

[0003] According to the Shanghai CCHH cross-sectional study in recent years, the prevalence of diseases and symptoms related to pollen is: asthma 10.2%, wheeze (ever) 28.1%, rhinitis (ever) 54.1%, pollen allergy 12.2%, eczema (ever) 22.7% and food allergy 15.7%. The prevalence of asthma has increased greatly, almost fivefold, from 2.1% in 1990 to 10.2%.

[0004] As people's living standards improve, their awareness of the harm of pollen is also increasing, and the monitoring of pollen in the air has been strengthened. Currently, some areas have provided daily pollen index reports, and there is also research on pollen detection and monitoring technology.

[0005] Currently, most pollen sampling equipment on the market is manual sampling, such as the Hirst sampler and the British Burkard sampler. The operator is required to scrape the preparation before sampling, and after sampling, the operator is required to perform manual microscopic classification and counting. Pollen forecast data can only be formed after regional aggregation. Manual pollen monitoring has a 24-hour release frequency and low timeliness; it is highly dependent on manpower, and the real and effective coverage area is limited; the cost of replication and promotion is high, it is difficult to provide continuous services, and it is difficult to form a monitoring network, etc., and it is impossible to form a broad and accurate pollen detection system.

[0006] In the existing patents, many technologies recorded in the patents have disclosed the fully automated process from automatic sampling, automatic sample delivery, automatic detection and analysis, such as an online monitoring system for pollen in the atmosphere with patent publication number CN105388093A, and a pollen monitoring method and device thereof with patent publication number CN111896430A; however, the existing automatic pollen detection technology still has the following problems:

[0007] First, the existing technologies all adopt the impact sampling method of pollen, but the current impact sampling method requires the sampling carrier (sampling carrier fragment or sampling film) to be enclosed and sealed before impact sampling to improve the accuracy of sampling, such as using an isolation cover to completely cover the sampling carrier, and then removing the isolation cover after the sampling is completed to facilitate the transfer of the sampling carrier. However, before the isolation cover completely covers the sampling carrier, it is difficult to adjust the moving distance of the isolation cover to achieve closure. If the moving distance is adjusted too large, it will cause impact. If the moving distance is too small, it will cause insufficient sealing.

[0008] Second, in the prior art, the sampling carrier is either rolled into a film and rolled up a section each time sampling is performed, or the sampling carriers (sampling slides) to be sampled / sampling is completed are stacked. However, whether rolling or stacking, the sampling carriers after sampling will be squeezed. On the one hand, the specimen is damaged after squeezing, which is not conducive to the subsequent retesting of the sampling situation, and is also not conducive to the extraction of a single test result. Summary of the invention

[0009] The present invention is intended to provide an online atmospheric pollen detection system to solve the problem of collision or poor sealing effect caused by the difficulty in adjusting the moving path of the isolation cover when it is closed in the prior art.

[0010] In order to achieve the above object, the present invention adopts the following technical scheme:

[0011] The atmospheric pollen online detection system includes a sampler, a transferor and an analyzer. The sampler is used to collect pollen. The transferor is used to transfer the sampling carrier on the sampler to the analyzer. The analyzer is used to analyze the pollen conditions on the sampling carrier. The sampler includes an isolation cover and a sampling carrier placement table installed in the isolation cover. The isolation cover includes an upper part and a lower part, and also includes a push block that drives the upper part or the lower part to move. After the push block moves, it is used to connect or separate the upper part with the lower part. An elastic member is connected between the push block and the isolation cover.

[0012] The principle and advantage of this solution are: before sampling, the upper part and the lower part are joined by pushing the push block. When joining, because there is a deformable elastic part connected between the push block and the isolation cover, the upper part and the lower part are joined slowly when joining, avoiding the collision / impact caused by the rapid joining of the upper part and the lower part. The push block is gradually pushed to make the upper part and the lower part join more tightly, which can ensure the sealing and the sealing effect; because the spring can be extended and retracted, there is no need to make a precise design of the moving distance of the push block, and it can also take into account the sealing performance and avoid hard collision. Therefore, compared with the existing technology, this solution reduces the difficulty of controlling the moving distance of the push block, and avoids the collision when the isolation cover is closed and the problem of poor sealing after sealing.

[0013] In addition, when the upper and lower parts of the isolation cover are close to each other, if there is a slight offset between the upper and lower parts and the upper and lower parts are not coaxial, the upper and lower parts can be automatically aligned and adjusted by slow soft connection.

[0014] Preferably, as an improvement, the push block is provided with a through hole, the isolation cover is provided with a screw hole, the screw passes through the through hole and is connected to the screw hole, there is a gap between the screw and the through hole, the elastic member is a spring, and the spring is sleeved on the screw.

[0015] Beneficial effects: This solution makes the installation of the elastic member simple and convenient, and can also adjust the maximum clamping force after the upper part and the lower part are joined by controlling the screwing depth of the screw, thereby improving practicality.

[0016] Preferably, as an improvement, the portion of the isolation cover connected to the push block is slidably connected to a provided slide rail to improve the stability of movement of the movable portion of the isolation cover.

[0017] Preferably, as an improvement, the analyzer includes a microscopic scanner and an adjustment mechanism located in the imaging area, the adjustment mechanism includes a support frame and an X / Y / Z displacement table that drives the support frame to move, the support frame is fixed at the output end of the X / Y / Z displacement table, and a specimen detection position is provided on the support frame.

[0018] Beneficial effect: This solution sets an X / Y / Z displacement stage on the analyzer so that when the microscope scanner observes the pollen on the sampling carrier, it can move the support frame through the X / Y / Z displacement stage, thereby realizing the movement of the specimen on the support frame, so as to ensure that the specimen can be moved to the microscope scanner to collect a clear image.

[0019] Preferably, as an improvement, the placement table is provided with a pickup port, which can be located below the sampling carrier, and the transfer device is provided with a transfer claw, which can move to the pickup port and lift the sampling carrier.

[0020] Beneficial effect: When this solution is adopted, the setting of the pickup port makes it convenient for the transfer claw to steadily hold up the sampling carrier, thereby ensuring the stability of the transfer of the sampling carrier.

[0021] Preferably, as an improvement, the transfer device further comprises a three-dimensional space mover, and the transfer claw is installed at the output end of the three-dimensional space mover.

[0022] Beneficial effects: This solution makes the transfer claw more flexible by arranging the transfer claw on the three-dimensional space mover, thereby reducing the size and position requirements for the analyzer and sampler.

[0023] Preferably, as an improvement, it further comprises a storage mechanism for storing the sampling carrier, the sampling carrier is a glass slide, the storage mechanism comprises a storage plate, and a plurality of glass slide storage positions are provided on the storage plate.

[0024] Beneficial effects: This solution enables multiple slides to be placed on different slide storage positions through the setting of the storage mechanism, which can ensure that the slides on each slide storage position do not affect each other, avoid damage problems caused by rolling or stacking the sampling carriers, and ensure that the sampled specimens can be transferred to the storage mechanism through the transferor after the analysis is completed, which is convenient for subsequent retesting of the specimens.

[0025] Preferably, as an improvement, the storage mechanism further comprises a rotating table for driving the storage plate to rotate, all the slide storage positions are located on the same circle concentric with the rotating table, and the slide storage positions are provided with retrieval notches for facilitating the transfer claws to retrieve the slides.

[0026] Beneficial effect: When this solution is adopted, all slides used as sampling carriers can be sampled or laid out at the same projection position, reducing the difficulty of path control of the transfer device, thereby ensuring the position accuracy of sampling and laying out, and the setting of the sampling notch facilitates sampling / layout by the transfer claw.

[0027] Preferably, as an improvement, the number of storage plates is at least two, and all storage plates are arranged at different heights to realize the utilization of height space, so as to facilitate placing more slides on the storage mechanism at one time, thereby meeting longer testing needs.

[0028] Preferably, as an improvement, adjacent storage plates are connected by connecting columns, and adjacent storage plates are isolated by shaft sleeves, which are sleeved on the connecting columns, ensuring that the spacing between upper and lower adjacent storage plates is the same, which helps to reduce the difficulty of controlling the transferor when taking / placing items. In addition, it also reduces the structural cost and installation difficulty of the storage mechanism.

[0029] All storage plates are strung on the same connecting column, and a shaft sleeve is also provided between the rotating table and the adjacent storage plates. The end of the connecting column close to the rotating table is fixedly connected to the output end of the rotating table to further reduce the cost and installation difficulty of the storage mechanism.

[0050] The embodiment is basically as shown in the attached Figures 1 to 18 shown.

[0051] The atmospheric pollen online detection system includes a housing and a sampler 1, a storage mechanism 2, a transferor 3 and an analyzer 4 located inside the housing (the housing is not shown in the figure).

[0054] The sampler 1 also includes a pusher 16 for driving the push block 14 to move. The pusher 16 drives the push block 14 to move closer to or away from the upper part of the isolation cover 11. The moving direction of the push block 14 is parallel to the length direction of the slide rail 13. In this embodiment, the pusher 16 is a screw motor. The output end of the screw stepper motor is fixedly connected to the push block 14 so that the push block 14 can move in a straight line.

[0055] A sealing ring is embedded in the lower base 113 of the isolation cover 11, and is used to improve the sealing after the lower base 113 is joined to the isolation tube 112. A column is integrally formed on the lower base 113, and the placement table 12 is detachably connected to the column by screws. A collection port 121 is provided on the placement table 12, and the collection port 121 can be located below the slide 10 to facilitate the transfer device 3 to take samples on the sampler 1.

[0056] The upper base 111 of the isolation cover 11 is connected to the sampling tube 17, and a nozzle 171 is fixed at one end of the sampling tube 17 facing the placement table 12, and the nozzle 171 has a rectangular shape. A rain cover 18 is installed at one end of the sampling tube 17 extending out of the box (that is, the rain cover 18 is installed at the top), and the rain cover 18 covers the end of the sampling tube 17. An insect net 19 is fixed between the top of the sampling tube 17 and the rain cover 18.

[0057] The storage mechanism 2 includes a storage plate 21 and a rotating table 22 that drives the storage plate 21 to rotate. The storage plate 21 is provided with a plurality of glass slide storage positions 211. All glass slide storage positions 211 are located on the same circle concentric with the rotating table 22. The glass slide storage positions 211 are provided with retrieval notches 212 for facilitating the transfer device 3 to retrieve items.

[0058] The number of storage plates 21 is at least two layers. In this embodiment, the number of storage plates 21 is three. All storage plates 21 are arranged at different heights. Adjacent storage plates 21 are connected by connecting columns 23. Adjacent storage plates 21 are isolated by shaft sleeves 24, and the shaft sleeves 24 are sleeved on the connecting columns 23. All storage plates 21 are strung on the same connecting column 23. A shaft sleeve 24 is also provided between the rotating table 22 and the adjacent storage plates 21. One end of the connecting column 23 close to the rotating table 22 is fixedly connected to the output end of the rotating table 22. Of course, the number of storage plates 21 can be adjusted according to actual needs.

[0059] The transfer device 3 includes a transfer claw 31 and a three-dimensional space mover that drives the transfer claw 31 to move in space. The transfer claw 31 is installed at the output end of the three-dimensional space mover. The transfer claw 31 is U-shaped. The U-shaped structure of the transfer claw 31 can be moved to the pickup port 121 of the sampler 1 and lift the glass slide 10. The transfer claw 31 can also be moved to the pickup notch 212 of the storage mechanism 2 to lift the glass slide 10. The U-shaped structure of the transfer claw 31 is provided with three sections of supporting protrusions for supporting the sampling carrier. The connecting line of the three sections of supporting protrusions is triangular. The supporting protrusions can ensure that the transfer claw 31 stably transfers the glass slide while reducing the contact area with the glass slide. The contact area is still located at the edge of the glass slide, which makes it more convenient for the rectangular nozzle of the nozzle 171 to gather pollen in the middle area of ​​the glass slide, which is beneficial to improving the accuracy of pollen detection and analysis.

[0060] In this embodiment, the three-dimensional space mover on the transfer device 3 includes a rotating seat 32, a Y-axis linear module 33 and a Z-axis linear module 34. The rotating seat 32 is used to drive the transfer claw 31 to rotate in the horizontal plane, the Y-axis linear module 33 is used to drive the transfer claw 31 to move horizontally, and the Z-axis linear module 34 is used to drive the transfer claw 31 to move up and down. Specifically, the Z-axis linear module 34 is installed at the output end of the rotating seat 32, and the Y-axis linear module 33 is installed at the output end of the Z-axis linear module 34.

[0061] The analyzer 4 includes a microscope scanner 41 and an adjustment mechanism located in the imaging area. The adjustment mechanism includes a support frame 42 and an X / Y / Z displacement table that drives the support frame 42 to move. The support frame 42 is fixed at the output end of the X / Y / Z displacement table. A specimen detection position 421 is opened on the support frame 42. The specimen detection position 421 is provided with a pickup port 121 that is the same as the slide 10 placement table 12.

[0062] In this embodiment, the X / Y / Z translation stage includes an X-axis screw stepper motor 43, a Y-axis screw stepper motor 44 and a Z-axis screw stepper motor 45. The X-axis screw stepper motor 43 is used to drive the support frame 42 to move along the horizontal X direction, the Y-axis screw stepper motor 44 is used to drive the support frame 42 to move along the horizontal Y direction, and the Z-axis screw stepper motor 45 is used to drive the support frame 42 to rise and fall. In more detail, the Z-axis screw stepper motor 45 is installed on the support arm of the microscanner 41, the output end of the Z-axis screw stepper motor 45 is installed with a stage 451, the Y-axis screw stepper motor 44 is fixed on the stage 451, the output end of the Y-axis screw stepper motor 44 is installed with a slide 441, the X-axis screw stepper motor 43 is fixed on the slide 441, and the support frame 42 is fixed on the output end of the X-axis screw stepper motor 43.

[0063] The specific online detection method of aerated pollen in this embodiment includes the following steps:

[0064] S1 . The transfer device 3 transfers the glass slide 10 on the storage mechanism 2 to the sampler 1 with the isolation cover 11 opened through the transfer claw 31 . The glass slide 10 is placed on the placement table 12 of the sampler 1 .

[0065] In this step, it is necessary to first place the circular glass slide 10 coated with the sampling agent on the storage position 211 of the storage mechanism 2; then, before the transfer device 3 takes the glass slide 10 in the storage position 211, first control the rotating table 22 to rotate so that the glass slide 10 to be taken is rotated to the specified position; then control the transfer device 3 to drive the transfer claw 31 to take away the glass slide 10.

[0066] S2. The upper and lower parts of the isolation cover 11 of the sampler 1 are joined to form a closed isolation cover 11. External air is drawn into the isolation cover 11 by negative pressure suction, and pollen contained in the external air collides with the glass slide 10 to collect pollen.

[0067] In this step, after the glass slide 10 is placed on the placement table 12, the pusher 16 is controlled to drive the push block 14 to rise. The push block 14 drives the lower part of the isolation cover 11 (that is, the lower base 113) to move upward and close to the upper part through the screw, so that the upper and lower parts of the isolation cover 11 are gradually closed during the rise of the push block 14. When the upper base 111 is engaged with the isolation tube 112, because a deformable spring 15 is connected between the push block 14 and the lower base 113, the lower base 113 and the isolation tube 112 are slowly engaged when engaged, avoiding the impact / impact caused by the rapid engagement of the upper and lower parts of the isolation cover 11, and gradually pushing the push block 14, so that the upper and lower parts are more closely engaged, the sealing can be ensured, and the sealing effect can be ensured; because the spring 15 can be retracted, there is no need to accurately design the moving distance of the push block 14, and the sealing performance and avoidance of hard impact can be taken into account. Therefore, this embodiment reduces the difficulty of controlling the moving distance of the push block 14, and avoids the impact of the isolation cover 11 when it is closed and the problem of poor sealing after sealing.

[0068] In this step, after the isolation cover 11 forms a closed space, the slide 10 is relatively close to the nozzle 171, with a distance of about 0.6 mm. The sampling nozzle 171 has a size of 14 mm in length and 2 mm in width, and the inner diameter of the sampling tube 17 is 12 mm.

[0069] S3 , the isolation cover 11 is opened, and the transfer device 3 transfers the sampled specimen slide 10 to the analyzer 4 through the transfer claw 31 , and the analyzer 4 performs detection and analysis.

[0070] In this step, during the pollen detection process, the specimen slide 10 placed on the support frame 42 is moved in space by the X / Y / Z translation stage on the analyzer 4 to perform microscopic focusing. After focusing is completed, the image collector is used to scan and photograph. The data transmission after scanning and photographing will be simultaneously backed up locally and transmitted to the AI ​​processing module for analysis. After the data is analyzed by AI, the type, concentration and quantity of pollen sampled this time are derived, and the microscopic scanning analysis process is completed.

[0071] S4. After the detection and analysis are completed, the transfer device 3 puts the specimen slide 10 on the analyzer 4 back onto the storage table on the storage mechanism 2.

[0072] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
