[0035] This embodiment discloses a bioaerosol detection system, such as Figure 1 As shown, it may include: a bioaerosol detection device 200 and a bioaerosol collection device 100 .

[0036] Among them, the bioaerosol collection device 100 includes a chassis 11, a sample collection device 13 and a sampling bottle 14. The sample collection device 13 is installed on the chassis 11, and the sampling bottle 14 is detachably connected to the sample collection device 13; the chassis 11 is used to drive the sample collection device 13 and the sampling bottle 14 to move relative to the bioaerosol detection device 200.

[0037] The bioaerosol detection device 200 includes a base station bracket 21 , and a detection device 22 , a sample rack 23 , a sample transport device, and a mechanical arm 24 installed on the base station bracket 21 .

[0038] The detection device 22 is installed at the lower part of the base station bracket 21, and the sample rack 23 is installed at the upper part of the base station bracket 21; the first end of the sample conveying device is connected to the sample rack 23, and the second end of the sample conveying device is connected to the detection device 22. The sample conveying device is used to transfer the sampling bottle 14 placed on the sample rack 23 to the detection device 22, so that the detection device 22 can detect the bioaerosol sample stored in the sampling bottle 14.

[0039] The mechanical arm 24 is installed in the middle of the base station bracket 21 , and is used to transfer the sampling bottle 14 from the sample rack 23 and connect it to the sample collection device 13 , or remove the sampling bottle 14 from the sample collection device 13 and transfer it to the sample rack 23 .

[0040] In this embodiment, if Figure 1 , Figure 3 As shown, the bioaerosol collection device 100 can complete the collection of bioaerosol samples at a specific time and place according to a predetermined procedure, following a certain time and route, and store them in a sampling bottle 14; the bioaerosol detection device 200 can receive the sampling bottle 14 from the bioaerosol collection device 100, detect the samples therein, and upload the detection data.

[0041] The chassis 11 is a supporting and driving component of the bioaerosol collection device 100. On the one hand, it provides fixed support for the sample collection device 13 and the sampling bottle 14; on the other hand, it drives the bioaerosol collection device 100 to move to a specific position along a specified path, thereby carrying out the collection operation and completing the collection task.

[0042] The sample collection device 13 contains a control circuit, which can complete the collection and delivery of bioaerosol samples according to a predetermined program, and can deliver the collected aerosol samples to the sampling bottle 14. The specific principle of the sample collection device 13 for collecting aerosols is not limited here, and can be flexibly selected according to actual application requirements, for example, it can be a sedimentation method, an inertial sampling method, or a filtration method.

[0043] The sampling bottle 14 is responsible for receiving the aerosol sample collected by the sample collection device 13 and storing it in the sampling bottle 14, and it is detachably connected to the sample collection device 13; the specific detachable connection method is not limited and can be flexibly selected according to actual application requirements. For example, the two can be detachably connected by snap-fitting or interference fitting, which facilitates the transfer of the sampling bottle 14 between the sample collection device 13 and the detection device 22 in the subsequent process.

[0044] The base station bracket 21 constitutes the main frame of the bioaerosol detection device 200. The specific material type and structure type are not limited and can be reasonably selected according to actual needs. For example, the material can be structural steel. It can be used to fix the detection device 22, the sample rack 23, the sample conveying device and the mechanical arm 24; at the same time, the side plate can be fixed on the outside to provide certain protection for the inside of the bioaerosol detection device 200.

[0045] The detection device 22 is a device specifically responsible for detecting the collected aerosol samples. On the one hand, it receives the sampling bottle 14 from the sample rack 23 through the sample conveying device and detects the samples therein; on the other hand, it can record the detection data of the sample and upload it to a specific server for storage, so as to facilitate viewing and management of the detection data.

[0046] The sample rack 23 is used to temporarily place the sampling bottle 14 and is a transfer component from the completion of sample collection to the start of detection. It can be fixed on the upper part of the base station bracket 21; its height can be close to the height of the sample collection device 13, which is convenient for the transfer of the sampling bottle 14.

[0047] The two ends of the sample conveying device are respectively connected to the sample rack 23 and the detection device 22, and are responsible for the transfer of the sampling bottle 14 between the two, completing the last step from sample collection to the start of detection. The specific type of the sample conveying device is not limited and can be flexibly selected according to actual needs. For example, it can be synchronous belt wheel transmission, robot gripping and conveying.

[0048] The robotic arm 24 has a grasping function. When the bioaerosol collection device 100 and the bioaerosol detection device 200 meet a certain relative position relationship, the robotic arm 24 can remove the sampling bottle 14 from the sample collection device 13 and place it on the sample rack 23, thereby completing the transfer of the sample between the bioaerosol collection device 100 and the bioaerosol detection device 200.

[0049] Aerosols are collected by a movable bioaerosol collection device 100, detected by a bioaerosol detection device 200, and the sample is transferred between the two by a robotic arm 24, thereby solving the problems commonly existing in current bioaerosol detection, such as limited collection locations and exposure risks due to reliance on manual operations.

[0050] In some embodiments, Figure 1 As shown, the bioaerosol detection system also includes a docking base 300, and the relative installation positions of the docking base 300 and the bioaerosol detection device 200 are fixed; the docking base 300 has a first docking mechanism 31, and the bioaerosol collection device 100 has a second docking mechanism 16 detachably connected to the first docking mechanism 31.

[0051] When the first docking mechanism 31 and the second docking mechanism 16 are in a connected state, the robotic arm 24 can transfer the sampling bottle 14 from the sample rack 23 and connect it to the sample collection device 13 , or remove the sampling bottle 14 from the sample collection device 13 and transfer it to the sample rack 23 .

[0052] In this embodiment, if Figure 1 As shown, the relative installation positions of the docking base 300 and the bioaerosol detection device 200 are required to be fixed. The specific implementation method is not limited and can be selected according to actual needs. For example, the position of the bioaerosol detection device 200 can be fixed first, and then the docking base 300 can be fixed to the wall or the ground according to a certain position relationship.

[0053] The first docking mechanism 31 and the second docking mechanism 16 can be equipped with a positioning module, so as to meet the smooth positioning and connection between the bioaerosol collection device 100 and the docking base 300. The relevant positioning principle is not limited here and can be flexibly selected according to actual needs. For example, it can be visual image positioning or Bluetooth positioning.

[0054] When the first docking mechanism 31 and the second docking mechanism 16 are in a connected state, the relative position of the first docking mechanism 31 and the second docking mechanism 16 is determined. At the same time, the first docking mechanism 31 is fixed to the docking base 300, the relative installation position of the docking base 300 and the bioaerosol detection device 200 is fixed, and the manipulator is fixedly installed on the bioaerosol detection device 200; the second docking mechanism 16 is detachably connected to the bioaerosol collection device 100. Therefore, the positions of the manipulator 24 and the sample collection device 13 are fixed, which facilitates the manipulator 24 to take and place the sampling bottle 14.

[0055] In some embodiments, Figure 1 , Figure 3 As shown, the docking base 300 has a charging interface; the bioaerosol collection device 100 has a power supply device 113 and a charging connector adapted to the charging interface, and the power supply device 113 is electrically connected to the charging connector.

[0056] When the first docking mechanism 31 and the second docking mechanism 16 are in a connected state, the charging interface and the charging connector are electrically connected, so that the power supply device 113 is in a charging state.

[0057] In this embodiment, if Figure 1 , Figure 3 As shown, the power supply device 113 can be one, fixed to the chassis 11, to provide power energy for the bioaerosol collection device 100; or it can be multiple, respectively fixed inside the chassis 11 and the sample collection device 13, to provide power to the chassis 11 and the sample collection device 13.

[0058] The docking base 300 has both a positioning function and a charging function. The bioaerosol collection device 100 can be charged while the robotic arm 24 is taking and placing the sampling bottle 14, making the entire system more efficient during use.

[0059] In some embodiments, Figure 2 As shown, the bioaerosol detection device 200 further includes a plurality of rolling wheels 25 mounted on the bottom of the bracket.

[0060] In this embodiment, if Figure 2 As shown, the bottom of the base station bracket 21 is the bottom of the bracket of the bioaerosol detection device 200 , on which the rolling wheels 25 are fixed. The number and material of the rolling wheels 25 are not limited and can be evenly distributed at the bottom of the base station bracket 21 .

[0061] Since the bioaerosol detection device 200 is large in size and weight, the setting of the rolling wheels 25 can support part of the weight of the bioaerosol detection device 200 on the one hand, and facilitate the adjustment of the position of the bioaerosol detection device 200 on the other hand, so as to facilitate the movement of the bioaerosol detection device 200 to different positions. At the same time, the uniform distribution of the rolling wheels 25 is also conducive to maintaining the stability of the bioaerosol detection device 200 during operation.

[0062] In some embodiments, Figure 2 As shown, the bioaerosol detection device 200 also includes a plurality of legs 26; the first end of the legs 26 along the height direction is connected to the bottom of the bracket, the second end of the legs 26 along the height direction has a supporting plane, and the heights of all the legs 26 are adjustable.

[0063] In this embodiment, if Figure 2 As shown, the number and material of the legs 26 are not limited and can be flexibly selected according to actual application requirements. The end of the legs 26 that contacts the ground can have a larger contact area to reduce the pressure of the legs 26 on the ground and avoid damage to the ground.

[0064] There is no limit to the height adjustment method of the support legs 26, and it can be flexibly selected according to actual needs. For example, a hydraulic cylinder can be selected.

[0065] When the bioaerosol detection device 200 needs to be moved, the height of the support foot 26 can be lowered so that the rolling wheel 25 is in full contact with the ground, ensuring that the support foot 26 does not hinder the movement of the rolling wheel 25; when the bioaerosol detection device 200 is in a suitable position and it is not desired to move, the height of the support foot 26 can be raised so that it is in full contact with the ground, thereby supporting the base station bracket 21.

[0066] In some embodiments, Figure 2As shown, the robotic arm 24 is a 6-DOF robotic arm 24, including an arm 241 and a gripping portion 242; the first end of the arm 241 is installed in the middle of the base station bracket 21, and the second end of the arm 241 is connected to the gripping portion 242; the gripping portion 242 is a five-finger dexterous hand.

[0067] In this embodiment, if Figure 2 As shown, the grasping portion 242 is a five-finger dexterous hand, which is responsible for grasping the sampling bottle 14. It can fit the outer wall of the sampling bottle 14 more closely, and can more conveniently remove or install the sampling bottle 14 from the sample collection device 13; it can more conveniently place the sampling bottle 14 on the sample rack 23, or take the sampling bottle 14 out of the sample rack 23.

[0068] The mechanical arm 24 has 6 degrees of freedom, which can meet the flexible transfer of the sampling bottle 14 between the sample collection device 13 and the sample rack 23.

[0069] In some embodiments, Figure 1 As shown, the bioaerosol detection system further includes a data server 32; the bioaerosol detection device 200 further includes a first communication device, and the bioaerosol collection device 100 further includes a second communication device; the first communication device and the second communication device are respectively connected to the data server 32 for communication.

[0070] In this embodiment, if Figure 1 As shown, the data server 32 is fixed to the base station bracket 21 , and the specific fixing position is not limited, for example, it can be fixed to the upper part of the base station bracket 21 .

[0071] The first communication device may be built in the detection device 22, or may be electrically connected to the detection device 22. A detection signal may be sent to the detection device 22, and detection data may be transmitted back to the data server 32.

[0072] The second communication device may be built into the sample collection device 13, or may be electrically connected to the sample collection device 13. A collection signal may be sent to the sample collection device 13, and a collection completion signal may be sent back to the data server 32 to wait for the next instruction.

[0073] The data server 32 can receive and store data from the first communication device and the second communication device, and can also send sampling or detection instruction signals to the first communication device and the second communication device. And it can meet the needs of remote management and access to data through a wired or wireless network. Therefore, the operation of the entire system and data transmission can be controlled by remote control.

[0074] In some embodiments, Figure 3As shown, the chassis 11 includes a mobile bracket 111, and a controller 112, a visual detection device 114, a walking wheel 115, a transmission assembly 116 and a driving motor 117 installed on the mobile bracket 111; the number of the walking wheels 115, the transmission assembly 116 and the driving motor 117 is the same and they are all multiple, and each walking wheel 115 is connected to the output shaft of a driving motor 117 through a set of transmission assemblies 116; the sample collection device 13 is installed on the mobile bracket 111.

[0075] The controller 112 is electrically connected to the drive motor 117, the visual detection device 114, and the second communication device; the visual detection device 114 is used to collect road condition detection data in real time and transmit the road condition detection data to the controller 112, so that the controller 112 can control the movement direction and speed of all the walking wheels 115 in real time through all the drive motors 117 and the transmission assembly 116 based on the road condition detection data and the sampling plan data sent by the data server 32 received through the second communication device.

[0076] In this embodiment, if Figure 3 As shown, the mobile bracket 111 constitutes one of the important frames of the chassis 11, on which components such as the controller 112, the power supply device 113, the visual detection device 114, the walking wheel 115, the transmission assembly 116 and the driving motor 117 can be fixedly connected.

[0077] The controller 112 can be one or several parts, which can control the speed and torque of the drive motor 117 and the movement state of the chassis 11; it can also receive and process the signal of the visual detection device 114 and provide timely feedback on the road conditions; it can also contact the data server 32 through the second communication device and issue instructions to multiple drive motors 117 regarding the next movement state.

[0078] The specific type of the visual detection device 114 is not limited and can be reasonably selected according to actual application requirements. For example, it can include at least one of a depth camera and a laser radar. The visual detection device 114 can collect road condition data in real time and transmit the data to the controller 112 respectively, so as to formulate a reasonable walking route and avoid obstacles in time.

[0079] The number of the running wheels 115, the transmission components 116 and the drive motor 117 is the same and multiple. The type of the transmission component 116 is not limited and can be flexibly selected according to the actual application requirements. For example, it can be a coupling. Each running wheel 115 is connected to the output shaft of a drive motor 117 through a set of transmission components 116, so that the output torque of the drive motor 117 is transmitted to the corresponding running wheel 115 through the corresponding transmission component 116; and each running wheel 115 can have a relatively independent motion state, realizing more flexible control of the motion posture.

[0080] Through the coordinated implementation of the above components, the bioaerosol collection device 100 can complete automatic collection according to the pre-set sampling path and sampling period, and cooperate with the subsequent bioaerosol detection device 200 to realize automatic sampling and detection of collected samples, thereby solving the problems of limited collection locations and exposure risks caused by reliance on manual operations that are common in current bioaerosol collection.

[0083] The data server 32 is used to generate sampling plan data according to the first position signal sent by the first communication device and the second position signal sent by the second communication device, and send the sampling plan data to the second communication device.

The specific installation location is not limited and can be flexibly selected according to actual applications. For example, it can be built into the sample collection device 13.

[0086] The use of the first positioning device and the second positioning device can facilitate the controller 112 to formulate a reasonable walking route. It is also convenient for the data server 32 to collect sample collection and detection information in real time, and to arrange sample collection and detection plans reasonably, avoiding the situation where multiple bioaerosol collection devices 100 are waiting for detection together, thereby improving the efficiency of bioaerosol collection and detection.

[0087] At the same time, by using a plurality of bioaerosol collection devices 100 , bioaerosol sample data from different locations can be obtained at the same time, which can improve the diversity of bioaerosol collection samples.

[0088] In some embodiments, Figure 3 , Figure 4As shown, the bioaerosol detection system further includes a height adjustment component 15 ; the bioaerosol collection device 100 further includes a mounting bracket 12 , the mounting bracket 12 is mounted above the mobile bracket 111 , and the sample collection device 13 is mounted above the mounting bracket 12 .

[0089] The first end of the height adjustment component 15 along the height direction is connected to the mobile bracket 111, and the second end along the height direction is connected to the mounting bracket 12, and the height adjustment component 15 is electrically connected to the controller 112; the height adjustment component 15 is used to drive the mounting bracket 12, the sample collection device 13 and the sampling bottle 14 to move along the height direction relative to the mobile bracket 111 according to the height control signal sent by the controller 112.

[0090] In this embodiment, if Figure 3 , Figure 4 As shown, the mounting bracket 12 is an intermediate body connecting the chassis 11 and the sample collection device 13. The connection method between the mounting bracket 12 and the sample collection device 13 is not limited and can be flexibly selected according to actual application requirements. For example, a detachable connection can be adopted, but it is necessary to ensure that the freedom of the sample collection device 13 in the horizontal direction relative to the mounting bracket 12 is 0. This can ensure that the movement state of the sample collection device 13 in the horizontal direction is consistent with that of the chassis 11, and can provide a certain height for the sample collection device 13.

[0091] The specific type of the height adjustment component 15 is not limited and can be flexibly selected according to actual application requirements. For example, it can be a hydraulic cylinder or a linear cylinder. Through this installation method, the height of the mounting bracket 12 can be adjusted and controlled, and bioaerosols at different heights can be collected.
