Description

Technical Field

[0001] This invention belongs to the field of dust monitoring technology, specifically relating to a real-time monitoring system and method for deposited dust in workplaces. Background Technology

[0002] In industrial production, the safety hazards posed by dust accumulation in workplaces cannot be ignored, especially the risk of dust explosions. Dust explosions not only threaten workers' lives but can also lead to severe economic losses. Dust generation and accumulation are particularly prominent in production-related dusty workplaces such as polishing and grinding workshops, large grain processing plants, stone processing plants, and wood processing plants. Although traditional dust collectors have played a role in reducing occupational hazards from dust, accumulated dust in various workplaces still poses a possibility of violent explosions when exposed to an ignition source, resulting in serious harm. The five elements of a dust explosion include oxidizing gases, combustible dust, an ignition source, a dust cloud, and a confined space. The combined effect of these elements can lead to catastrophic consequences. One characteristic of dust explosions is the potential for multiple explosions. The shock wave from the initial explosion can lift accumulated dust from other areas, forming a dust cloud and triggering secondary explosions, the latter often having a much larger impact range and greater power than the initial explosion.

[0003] By adopting effective dust monitoring technologies, timely warnings can be issued when dust concentrations exceed limits, thereby significantly reducing the risk of dust explosions and providing strong protection for industrial production safety. Therefore, in order to effectively reduce the occurrence of dust explosion accidents and protect the lives of workers and the property of enterprises, there is an urgent need to provide a real-time dust monitoring system and method for workplaces. Summary of the Invention

[0004] To address the aforementioned problems in the prior art, this invention provides a real-time monitoring system and method for dust deposition in workplaces. This system features a reasonable structure, low manufacturing cost, ideal real-time monitoring effect, superior continuous monitoring performance, and high monitoring efficiency. It can efficiently and accurately monitor the amount of dust falling into the workplace in real time, continuously, and precisely, significantly improving the safety of the working environment and providing strong technical support for industrial production safety. The method is highly intelligent, achieving ideal monitoring effect and high accuracy for deposited dust. It effectively solves the problem of insufficient monitoring methods for dust deposition in workplaces in existing technologies, providing reliable technical support for dust control and occupational health protection. Simultaneously, it provides strong technical support for the safety management of the working environment.

[0005] To achieve the above objectives, the present invention provides a real-time monitoring system for dust deposition in workplaces, comprising a housing, a semiconductor strain gauge dust monitoring unit, a self-cleaning unit, an adaptive identification unit, and a data acquisition and processing unit.

[0006] The interior of the housing forms a dust monitoring chamber. A dust settling port communicating with the dust monitoring chamber is provided on the top plate of the housing. A chamber cover is connected to one side of the dust settling port via an electric hinge. The chamber cover is used to open or close the dust settling port under the control of the electric hinge.

[0007] The semiconductor strain gauge dust monitoring unit is installed in the dust monitoring chamber and includes a dust lifting transmission mechanism, a dust rotation transmission mechanism, a dust telescopic connecting rod, a measuring base, a first detection plate, and a second detection plate. The dust lifting transmission mechanism is vertically fixedly installed in the upper part of the dust monitoring chamber and located on the right side of the dust settling inlet. The dust rotation transmission mechanism is horizontally installed at the end of the lifting end of the dust lifting transmission mechanism. The dust telescopic connecting rod is horizontally arranged, with one end connected to the output end of the dust rotation transmission mechanism and the other end extending into the interior of the area where the dust settling inlet is located. The measuring base is located below the dust settling inlet and is fixedly fitted onto the outside of the other end of the dust telescopic connecting rod through a mounting hole at its thickness center. The first and second detection plates are both sheet-like structures made of semiconductor strain gauges, both horizontally arranged, and installed opposite each other on the upper and lower sides of the measuring base.

[0008] The self-cleaning unit is located in the dust monitoring chamber, below the measuring base. The self-cleaning unit includes a dust mass balance, a dust collection cylinder, a rotating disc, a cleaning device, and a spraying device. The dust mass balance is located below the dust settling inlet and installed in the dust monitoring chamber. The upper end of the dust collection cylinder is open and is mounted on the weighing pan of the dust mass balance. The rotating disc is installed above the dust collection cylinder, with a material discharge channel in the central area corresponding to the dust collection cylinder, and a horizontal rotating disc surface at its upper end. The cleaning device includes a cleaning lifting transmission mechanism, a cleaning electric telescopic rod, and a cleaning head. The cleaning lifting transmission mechanism is vertically mounted at one end of the rotating disc surface. The cleaning electric telescopic rod is horizontally mounted at the lifting end of the cleaning lifting transmission mechanism. The telescopic rod extends laterally to a position close to the center of the measuring base; the cleaning head is fitted onto the outside of the telescopic end of the cleaning electric telescopic rod; the spraying device includes a spraying lifting transmission mechanism, a spraying electric telescopic rod, a spray head, and a pressurized water supply assembly; the spraying lifting transmission mechanism is vertically installed at the other end of the rotating disk; the spraying electric telescopic rod is laterally installed at the end of the lifting end of the spraying lifting transmission mechanism, with its telescopic rod end extending laterally to a position close to the center of the measuring base; the spray head is installed outside the telescopic end of the spraying electric telescopic rod, and multiple spray outlets are provided at the end of the spray head near the cleaning head and at the top; the pressurized water supply assembly is installed outside or inside the housing and is connected to the water inlet of the spray head via a hose with an electrically controlled valve connected in series for supplying pressurized water;

[0009] The adaptive recognition unit includes an adaptive recognition light group and an adaptive recognition module; the adaptive recognition light group is installed on the outer surface of the housing; the adaptive recognition module is installed inside or outside the housing and is connected to the adaptive recognition light group.

[0010] The data acquisition and processing unit includes a power module, a motion control module, a communication module, a control terminal, and a data processor. The power module supplies power. The motion control module is connected to the electric hinge, the dust collection lifting transmission mechanism, the dust collection rotation transmission mechanism, the rotary disk, the sweeping lifting transmission mechanism, the sweeping electric telescopic rod, the spray lifting transmission mechanism, the spraying electric telescopic rod, and the electrically controlled valve. The control terminal is located in the monitoring center. The data processor is connected to the first detection plate, the second detection plate, the dust collection quality balance, the adaptive recognition module, the motion control module, and the communication module. It is also connected to the control terminal via the communication module.

[0011] As a preferred embodiment, the shell is cubic in shape; the dust settling port is rectangular in shape.

[0012] Furthermore, to improve moisture absorption and ensure a clean wiping process, the cleaning head is made of cotton.

[0013] As a preferred embodiment, the control terminal is an industrial computer.

[0014] As a preferred embodiment, the first and second detection plates are of the same size, and both are smaller than the size of the dust settling port.

[0015] Furthermore, to ensure effective dust collection, the size of the opening at the top of the dust collection cylinder is larger than the sizes of the first and second detection plates.

[0016] Furthermore, in order to ensure that the cleaning of one test piece does not adversely affect the normal monitoring operation of the other test piece, the first test piece is connected to the measuring base through a first shock-absorbing connection assembly, and the second test piece is connected to the measuring base through a second shock-absorbing connection assembly.

[0017] In this invention, the chamber cover is connected to one side edge of the dust settling port using an electric hinge, which facilitates automatic control of the chamber cover's movement and allows for convenient switching between the open and semi-closed states of the dust settling port. Thus, when the dust settling port is closed, the dust monitoring chamber is effectively isolated from the outside world, and when the dust settling port is open, the dust monitoring chamber is directly connected to the outside world, facilitating direct dust monitoring operations. The measuring base is positioned below the dust settling inlet, and the first and second detection plates are installed opposite each other on the upper and lower sides of the measuring base. The measuring base is connected to the dust collection telescopic linkage, which is then connected to the output end of the dust collection rotary transmission mechanism. The dust collection rotary transmission mechanism is installed above the dust collection lifting transmission mechanism. This allows the measuring base to rotate using the rotation of the dust collection rotary transmission mechanism, and the height of the measuring base within the dust collection monitoring chamber can be adjusted using the lifting action of the dust collection lifting transmission mechanism. Furthermore, the lateral position of the measuring base can be changed by manually adjusting the length of the dust collection telescopic linkage. Therefore, the first or second detection plate can be flexibly adjusted to the detection position according to different working conditions, and the height of the detection plate can also be flexibly adjusted. By mounting the first and second detection plates below the dust settling inlet on the measuring base, the likelihood of dust spreading to other areas during monitoring operations can be effectively reduced. This ensures that all dust falling into the dust settling inlet is deposited on either the first or second detection plate, thereby effectively ensuring the monitoring effect and accuracy of the deposited dust. By installing a self-cleaning unit below the measuring base, it is convenient to simultaneously clean the other detection plate (located below) when one is in the upper detection position. This effectively cleans the dust deposited on the used detection plate, preparing it for the next dust monitoring. This alternating use of the two detection plates effectively ensures continuous measurement of deposited dust in the work area. Installing the dust collection cylinder on a dust mass balance facilitates the centralized collection of falling dust. It also allows for real-time online weighing of the collected dust, enabling the determination of dust levels in the cylinder based on the weighing data. This allows for timely alerts and warnings to clean the cylinder when dust levels are high. A rotating disc is installed at the top of the dust collection cylinder, with a material discharge channel at its center. This ensures that dust falling during the cleaning of the testing plates can fall unimpeded into the dust collection cylinder, effectively ensuring centralized dust collection.A cleaning device and a spraying device are installed at opposite ends of the rotating disk. This design facilitates effective cleaning through the coordinated action of the cleaning and spraying devices, while also improving cleaning efficiency through the rotation of the disk. Furthermore, it ensures that the spraying and cleaning devices effectively cover the entire surface of the test piece, guaranteeing thorough cleaning of all parts and significantly increasing cleaning efficiency. The cleaning head is mounted on an electric telescopic cleaning rod, which is then installed on the upper end of the cleaning lifting transmission mechanism. This allows for lateral movement of the cleaning head using the electric telescopic cleaning rod and vertical movement using the cleaning lifting transmission mechanism. This enables flexible adjustment of the cleaning head's position relative to the test piece, facilitating comprehensive cleaning. The spray head has multiple spray outlets at both the end near the cleaning head and the top. When pressurized water is supplied, the multiple spray outlets near the cleaning head can spray mist-like droplets onto the cleaning head, thus wetting it and improving cleaning effectiveness and efficiency. Simultaneously, the multiple spray outlets at the top can also spray mist-like droplets onto the surface of the test piece to be cleaned, further wetting the surface and improving cleaning efficiency and effectiveness. The spray head is mounted on an electric telescopic spray rod, which is then mounted on the upper end of the spray lifting transmission mechanism. This allows for easy lateral movement of the spray head using the electric telescopic rod and vertical lifting of the spray head using the spray lifting transmission mechanism, enabling flexible movement according to different needs. The pressurized water supply component is connected to the spray head via a hose with an electrically controlled valve, ensuring a reliable supply of pressurized water and facilitating easy control of the spray head's start and stop. The adaptive identification module is connected to both the adaptive identification light group and the data processor. Simultaneously, the data processor is connected to both the first and second detection plates. This allows the data processor to control the adaptive identification light group to emit different lights based on different operating conditions when collecting dust quality data using either the first or second detection plate. This enables differentiated alarm actions for different conditions, effectively alerting personnel to take appropriate countermeasures based on the alarm type. The control terminal is configured for real-time communication with the data processor, allowing for real-time display of monitoring data and alarm information, facilitating more comprehensive and intelligent monitoring operations.

[0018] This system has the advantages of reasonable structure, low manufacturing cost, ideal real-time monitoring effect, excellent continuous monitoring performance and high monitoring efficiency. It can effectively improve the automation level of dust monitoring work, and can efficiently and accurately realize real-time, continuous and precise monitoring of dust in the workplace, significantly improving the safety of the working environment and providing strong technical support for the safety of industrial production.

[0019] This invention also provides a method for real-time monitoring of dust deposits in the workplace, employing a real-time dust deposit monitoring system in the workplace, comprising the following steps:

[0020] Step 1: Preparation;

[0021] First, place the real-time dust monitoring system horizontally in the workplace to be tested, ensuring the chamber cover is closed during this process; then establish a communication connection between the control terminal and the data processor.

[0022] Step 2: Record the initial empty weight;

[0023] Power is supplied by a power module to start the real-time dust monitoring system in the workplace. Before the monitoring operation begins, the data processor receives the initial strain signals one and two from the first and second detection plates, respectively. Based on the initial strain signals one and two, the initial empty weight one N-1 of the first detection plate and the initial empty weight two M-1 of the second detection plate are obtained. The data is then uploaded to the control terminal through the communication module. The control terminal receives the initial empty weight one N-1 and the initial empty weight two M-1, records them, and displays them in real time.

[0024] Step 3: Conduct real-time continuous dust monitoring.

[0025] S1: Ensure the first detection piece is in the detection position on the upper side; at the same time, send an opening signal to the motion control module through the data processor. After receiving the opening signal, the motion control module controls the electric hinge to rotate the chamber cover to the open state, so that the dust monitoring chamber can be connected to the external working environment through the dust settling port.

[0026] S2: Real-time monitoring of dust in the workplace is performed using the first detection element. The first detection element receives dust in the environment in real time and sends the real-time strain signal to the data processor. The data processor obtains real-time strain data based on the real-time strain signal and matches it with real-time dust quality data. At the same time, the real-time dust quality data is uploaded to the control terminal through the communication module. The control terminal receives the real-time dust quality data and records and displays it in real time.

[0027] If the real-time dust quality data does not increase within a one-hour monitoring period, the data processor sends a Level 1 alarm signal to the adaptive recognition module. Upon receiving the Level 1 alarm signal, the adaptive recognition module controls the yellow alarm light in the adaptive recognition light group to flash.

[0028] S3: After the single-sided monitoring time of the first detection piece is reached, the dust deposited on the first detection piece has reached its measurement limit. At this time, the data processor obtains the stage dust quality data one and uploads it to the control terminal through the communication module. After receiving the stage dust quality data one, the control terminal records and displays it in real time. The data processor sends a rotation action signal one to the motion control module. After receiving the rotation action signal one, the motion control module controls the dust lifting transmission mechanism to execute action one, so that the dust lifting transmission mechanism drives the dust telescopic linkage and the measuring base to rotate 180 degrees, and drives the second detection piece to rotate to the upper detection position.

[0029] S4: Real-time monitoring of dust in the workplace is performed using a second detection element. The second detection element receives dust in the environment in real time and sends the real-time strain signal 2 to the data processor to achieve continuous monitoring of dust deposits in the workplace. The data processor obtains real-time strain data 2 based on the real-time strain signal 2, and matches it with real-time dust quality data 2. At the same time, the real-time dust quality data 2 is uploaded to the control terminal through the communication module. After receiving the real-time dust quality data 2, the control terminal records and displays it in real time.

[0030] If the real-time dust quality data does not increase within a one-hour monitoring period, the data processor sends a Level 1 alarm signal to the adaptive recognition module. Upon receiving the Level 1 alarm signal, the adaptive recognition module controls the yellow alarm light in the adaptive recognition light group to flash.

[0031] During the real-time monitoring of dust accumulation in the workplace using the second detection plate, the first detection plate is simultaneously cleaned. A cleaning signal is sent from the data processor to the motion control module. Upon receiving the cleaning signal, the motion control module first controls the sweeping electric telescopic rod to push the cleaning head laterally towards the center of the measuring base, and then controls the spraying electric telescopic rod to push the spray head laterally towards the center of the measuring base. Next, it controls the electronically controlled valve to open, causing multiple spray outlets near the cleaning head to spray atomized droplets and wet the cleaning head. Simultaneously, multiple spray outlets at the top of the spray head spray atomized droplets and wet the surface of the first detection plate. Next, the following control actions are performed sequentially: controlling the spraying electric telescopic rod to retract laterally to a fully retracted state; controlling the spraying lifting transmission mechanism to retract vertically to a fully retracted state; controlling the sweeping electric telescopic rod to push the cleaning head laterally to the lower right half of the measuring base; and controlling the sweeping lifting transmission mechanism... The moving mechanism pushes the cleaning head vertically to contact the surface of the first detection plate. Then, the rotating disk drives the sweeping and spraying devices to rotate at a constant speed. Simultaneously, the electric telescopic sweeping rod drives the cleaning head to reciprocate laterally to ensure the dust adhering to the first detection plate is cleaned. Meanwhile, the falling dust falls into the dust collection cylinder through the material discharge channel in the center of the rotating disk. Finally, after a set time for continuous sweeping, the sweeping operation is completed. The sweeping lifting transmission mechanism is first controlled to retract vertically to a fully retracted state, and then the electric telescopic sweeping rod is controlled to retract laterally to a fully retracted state to ensure no interference occurs during the rotation of the measuring base. Simultaneously, the dust collection cylinder weighs the falling dust and sends the dust mass A1 to the data processor. Upon receiving the dust mass A1, the data processor uploads it to the control terminal via the communication module. The control terminal receives the dust mass A1 and records and displays it in real time.

[0032] S5: After the single-sided monitoring time of the second detection piece is reached, the dust deposited on the second detection piece has reached its measurement limit. At this time, the data processor obtains the stage dust mass data two and uploads it to the control terminal through the communication module. After receiving the stage dust mass data two, the control terminal records and displays it in real time. The data processor sends a rotation action signal two to the motion control module. After receiving the rotation action signal two, the motion control module controls the dust falling rotation transmission mechanism to execute action two, so that the dust falling rotation transmission mechanism drives the dust falling telescopic link and the measuring base to rotate 180 degrees, driving the first detection piece to rotate to the upper detection position. At the same time, the data processor receives the updated strain signal one of the first detection piece and obtains the updated empty weight one N of the first detection piece according to the updated strain signal one, and then uploads it to the control terminal through the communication module. The control terminal receives the updated empty weight one N and records and displays it in real time.

[0033] S6: Repeat S2 to perform real-time monitoring of dust in the workplace using the first detection plate;

[0034] Simultaneously, during the real-time monitoring of dust accumulation at the work site using the first detection plate, the second detection plate is cleaned concurrently. A second cleaning signal is sent to the motion control module via the data processor. Upon receiving this signal, the motion control module first controls the electric telescopic sweeping rod to push the cleaning head laterally towards the center of the measuring base, then controls the electric telescopic spraying rod to push the spray head laterally towards the center of the measuring base. Next, it controls the electronically controlled valve to open, causing multiple spray outlets near the cleaning head to spray atomized droplets and wet the cleaning head. Simultaneously, multiple spray outlets at the top of the spray head spray atomized droplets to wet the surface of the second detection plate. Next, the following control actions are performed sequentially: controlling the electric telescopic spraying rod to retract laterally to a fully retracted state; controlling the spraying lifting transmission mechanism to retract vertically to a fully retracted state; controlling the electric telescopic sweeping rod to push the cleaning head laterally to the lower right half of the measuring base; and controlling the sweeping lifting... The transmission mechanism vertically pushes the cleaning head to contact the surface of the second detection plate. Then, the rotating disk drives the sweeping and spraying devices to rotate at a constant speed. Simultaneously, the electric telescopic sweeping rod drives the cleaning head to reciprocate laterally to ensure the dust adhering to the second detection plate is cleaned. Meanwhile, the falling dust falls into the dust collection cylinder through the material drop channel in the center of the rotating disk. Finally, after a set time for continuous sweeping, the sweeping operation is completed. The sweeping lifting transmission mechanism is first controlled to retract vertically to a fully retracted state, and then the electric telescopic sweeping rod is controlled to retract laterally to a fully retracted state to ensure no interference occurs during the rotation of the measuring base. Simultaneously, the dust collection cylinder weighs the falling dust and sends the dust mass A2 to the data processor. Upon receiving the dust mass A2, the data processor uploads it to the control terminal via the communication module. The control terminal receives the dust mass A2, records it, and displays it in real time.

[0035] S7: Repeat S3; at the same time, receive the updated strain signal 2 of the second detection piece through the data processor, obtain the updated empty weight 2M of the second detection piece according to the updated strain signal 2, and then upload it to the control terminal through the communication module. The control terminal receives the updated empty weight 2M and records and displays it in real time.

[0036] S8: Repeat S4 and S5. At the same time, the data processor receives the updated strain signal 2 of the first detection piece and obtains the updated empty weight 1N+1 of the first detection piece according to the updated strain signal 2. Then, it is uploaded to the control terminal through the communication module. The control terminal receives the updated empty weight 1N+1 and records and displays it in real time.

[0037] If the difference between the three values ​​N, N-1, and N+1 is less than 10%, it is determined that the first detection piece can still be used normally, and S9 continues; if the difference between the three values ​​N, N-1, and N+1 is greater than or equal to 10%, it is determined that spraying and wiping alone cannot thoroughly clean it or the detection piece has been severely worn and needs to be replaced. At this time, the data processor sends a secondary alarm signal to the adaptive recognition module. After receiving the secondary alarm signal, the adaptive recognition module controls the red alarm light in the adaptive recognition light group to flash. At the same time, the data processor sends a stop signal to the motion control module. After receiving the stop signal, the motion control module controls each component to stop moving and directly executes step four.

[0038] S9: Repeat S6 and S7, and obtain the updated empty weight 2 M+1 during the execution of S7, and then upload it to the control terminal through the communication module. The control terminal receives the updated empty weight 2 M+1, records it and displays it in real time.

[0039] If the difference between the three values ​​M, M-1, and M+1 is less than 10%, the second detection piece 10 is considered to still be usable, and S10 continues. If the difference between the three values ​​M, M-1, and M+1 is greater than or equal to 10%, it is determined that spraying and wiping alone are insufficient to thoroughly clean the piece or that the detection piece is severely worn and needs to be replaced. In this case, the data processor sends a secondary alarm signal to the adaptive recognition module. Upon receiving the secondary alarm signal, the adaptive recognition module controls the red alarm light in the adaptive recognition light group to flash. At the same time, the data processor sends a stop signal to the motion control module. Upon receiving the stop signal, the motion control module controls all components to stop moving and directly executes step four.

[0040] S10: Repeat S4 to S9 multiple times. At the same time, when executing S8, use the latest obtained values ​​of N, N-1, and N+1 to determine whether the first detection plate can be used normally. When executing S9, use the latest obtained values ​​of M, M-1, and M+1 to determine whether the second detection plate can be used normally, until the real-time continuous monitoring of the dust deposited in the work area is completed.

[0041] Step 4: End the monitoring operation;

[0042] The control power module disconnects the power supply to each electrical device, thus ending the monitoring operation.

[0043] As a preferred embodiment, in step two, ensure that the first detection piece is in the upper detection position. If the first detection piece is in the lower position, send a rotation action signal three to the motion control module through the data processor. After receiving the rotation action signal three, the motion control module controls the dust-falling rotation transmission mechanism to execute action three, so that the dust-falling rotation transmission mechanism drives the dust-falling telescopic connecting rod and the measuring base to rotate by a set angle, thereby rotating the first detection piece to the upper detection position.

[0044] Furthermore, to facilitate timely cleaning of the dust collection cylinder when it is in a state of accumulating a large amount of dust, and to avoid the situation where the accuracy of monitoring data is affected by the large amount of dust in the dust collection cylinder, in steps S8, S9 and S10 of step three, when the cumulative value of dust mass exceeds the maximum threshold, the data processor sends a cleaning cylinder signal to the adaptive identification module. Upon receiving the cleaning cylinder signal, the adaptive identification module controls the orange alarm light in the adaptive identification light group to flash. At the same time, the data processor sends a stop signal to the motion control module. After receiving the stop signal, the motion control module controls all components to stop moving and sends a cleaning cylinder reminder message to the control terminal through the communication module. The control terminal receives the cleaning cylinder reminder message and displays it in real time.

[0045] This invention boasts a high degree of intelligence, eliminating the need for manual intervention throughout the monitoring process. This reduces labor intensity while effectively ensuring monitoring accuracy. The method automatically performs real-time, continuous, and precise detection of dust quality within the target space, significantly improving the accuracy and convenience of dust monitoring. Furthermore, it offers ideal monitoring results and high precision for deposited dust, effectively addressing the shortcomings of existing workplace dust monitoring methods. This provides reliable technical support for dust control and occupational health protection, and also offers strong technical support for safe management of the work environment.

[0050] The invention will now be further described with reference to the accompanying drawings.

[0051] like Figures 1 to 3 As shown, the present invention provides a real-time monitoring system for dust deposition in the workplace, including a housing 1, a semiconductor strain gauge dust monitoring unit 2, a self-cleaning unit 3, an adaptive identification unit 4, and a data acquisition and processing unit 5;

[0052] The interior of the housing 1 forms a dust monitoring chamber 8. A dust settling port 6 communicating with the dust monitoring chamber 8 is provided on the top plate of the housing 1. A chamber cover 7 is connected to one side of the dust settling port 6 by an electric hinge. The chamber cover 7 is used to open or close the dust settling port 6 under the control of the electric hinge. In this way, when the dust settling port 6 is closed, the dust monitoring chamber 8 can be effectively isolated from the outside.

[0053] As a preferred option, the dust monitoring chamber 8 is cubic in shape;

[0054] The semiconductor strain gauge dust monitoring unit 2 is installed in the dust monitoring chamber 8, and includes a dust lifting transmission mechanism 13, a dust rotation transmission mechanism 32, a dust telescopic connecting rod 12, a measuring base 11, a first detection plate 9, and a second detection plate 10. The dust lifting transmission mechanism 13 is vertically fixedly installed in the upper part of the dust monitoring chamber 8 and is located on the right side of the dust settling port 6. The dust rotation transmission mechanism 32 is horizontally installed at the end of the lifting end of the dust lifting transmission mechanism 13. The dust telescopic connecting rod 12 is horizontally arranged, with one end connected to the output end of the dust rotation transmission mechanism 32 and the other end extending to the dust settling port 6. The measuring base 11 is located below the dust settling inlet 6 and is fixedly mounted on the outside of the other end of the dust-collecting telescopic connecting rod 12 through the mounting hole at the center of its thickness direction. The first detection plate 9 and the second detection plate 10 are both sheet-like structures made of semiconductor strain gauges. Both are horizontally arranged and installed on the upper and lower sides of the measuring base 11 respectively. The first detection plate 9 and the second detection plate 10 are used for real-time monitoring and measurement of dust deposited in the workplace. After dust accumulates on them, their strain state changes and they will emit corresponding strain signals. The corresponding strain data can be easily obtained through the strain signals.

[0055] As a preferred embodiment, an installation platform 33 is installed on the upper right side of the dust monitoring chamber 8, and the dust lifting transmission mechanism 13 is installed on the installation platform 33.

[0056] The self-cleaning unit 3 is installed in the dust monitoring chamber 8 and below the measuring base 11. The self-cleaning unit 3 includes a dust mass balance 18, a dust collection cylinder 17, a rotating disk 14, a cleaning device 15, and a spraying device 16. The dust mass balance 18 is located below the dust settling inlet 6 and is installed in the dust monitoring chamber 8. The upper end of the dust collection cylinder 17 is open, also located below the dust settling inlet 6, and is mounted on the weighing pan of the dust mass balance 18 to measure the mass of dust collected by the dust collection cylinder 17. The rotating disk 14 is installed above the dust collection cylinder 17, with its center... The area corresponding to the dust collection cylinder 17 has a material discharge channel with a horizontal rotating disk at its upper end. This material discharge channel ensures that dust falling from the test piece accurately falls into the dust collection cylinder 17. The cleaning device 15 includes a cleaning lifting transmission mechanism 21, a cleaning electric telescopic rod 20, and a cleaning head 19. The cleaning lifting transmission mechanism 21 is vertically mounted at one end of the rotating disk. The cleaning electric telescopic rod 20 is horizontally mounted at the lifting end of the cleaning lifting transmission mechanism 21, with its telescopic end extending laterally to a position close to the center of the measuring base 11. The cleaning head 19 is fitted onto the outside of the telescopic end of the cleaning electric telescopic rod 20. Thus, driven by the cleaning lifting transmission mechanism 21, the cleaning head 10 can reciprocate vertically up and down. Simultaneously, driven by the heat-dissipating electric telescopic rod 20, the cleaning head 10 can also reciprocate horizontally left and right, thereby flexibly achieving the purpose of cleaning the inspection plate. The spraying device 16 includes a spraying lifting transmission mechanism 24, a spraying electric telescopic rod 23, a spray head 22, and a pressurized water supply assembly. The spraying lifting transmission mechanism 24 is vertically installed at the other end of the rotating disk. The spraying electric telescopic rod 23 is horizontally installed at the end of the lifting end of the spraying lifting transmission mechanism 24, with its telescopic rod end extending horizontally. The spray head 22 is installed on the outside of the telescopic end of the electric telescopic spray rod 23. Multiple spray outlets are provided at the inner end (the end near the cleaning head 19, so that a mist can be sprayed onto the cleaning head 19 to achieve effective wetting) and the upper end of the spray head 22. The pressurized water supply component is installed on the outside or inside of the housing 1 and is connected to the water inlet of the spray head 22 through a hose with an electrically controlled valve connected in series for supplying pressurized water. In this way, the self-cleaning unit 3 can clean the measuring surface by liquid spraying and physical wiping through the cooperation of the cleaning device 15 and the spraying device 16.

[0057] The adaptive recognition unit 4 includes an adaptive recognition light group 25 and an adaptive recognition module 26; the adaptive recognition light group 25 is installed on the outer surface of the housing 1; the adaptive recognition module 26 is installed inside or outside the housing 1 and is connected to the adaptive recognition light group 25.

[0058] The data acquisition and processing unit 5 includes a power module 30, a motion control module 28, a communication module 29, a control terminal 27, and a data processor 31. The power module 30 is used to supply power and is connected to each power-consuming component. The motion control module 28 is connected to the electric hinge, the dust collection lifting transmission mechanism 13, the dust collection rotation transmission mechanism 32, the rotary disk 14, the sweeping lifting transmission mechanism 21, the sweeping electric telescopic rod 20, the spray lifting transmission mechanism 24, the spraying electric telescopic rod 23, and the electrically controlled valve. The control terminal 27 is located in the monitoring center. The data processor 31 is connected to the first detection plate 9, the second detection plate 10, the dust collection quality balance 18, the adaptive recognition module 26, the motion control module 28, and the communication module 29. It is also connected to the control terminal 27 through the communication module 29.

[0059] As a preferred embodiment, the shell 1 has a cubic structure; the dust settling port 6 is rectangular.

[0060] To improve moisture absorption and ensure a clean wiping process, the cleaning head 19 is made of cotton.

[0061] As a preferred embodiment, the control terminal 27 is an industrial computer.

[0062] As a preferred embodiment, the first detection piece 9 and the second detection piece 10 are the same size, and both are smaller than the size of the dust settling port 6.

[0063] To ensure effective dust collection, the size of the opening at the top of the dust collection cylinder 17 is larger than the sizes of the first detection plate 9 and the second detection plate 10.

[0064] To ensure that cleaning one test piece does not adversely affect the normal monitoring operation of the other test piece, the first test piece 9 is connected to the measuring base 11 via a first shock-absorbing connection assembly, and the second test piece 10 is connected to the measuring base 11 via a second shock-absorbing connection assembly.

[0065] In this invention, the chamber cover is connected to one side edge of the dust settling port using an electric hinge, which facilitates automatic control of the chamber cover's movement and allows for convenient switching between the open and semi-closed states of the dust settling port. Thus, when the dust settling port is closed, the dust monitoring chamber is effectively isolated from the outside world, and when the dust settling port is open, the dust monitoring chamber is directly connected to the outside world, facilitating direct dust monitoring operations. The measuring base is positioned below the dust settling inlet, and the first and second detection plates are installed opposite each other on the upper and lower sides of the measuring base. The measuring base is connected to the dust collection telescopic linkage, which is then connected to the output end of the dust collection rotary transmission mechanism. The dust collection rotary transmission mechanism is installed on the upper end of the dust collection lifting transmission mechanism. This allows the measuring base to rotate using the rotation of the dust collection rotary transmission mechanism, and the height of the measuring base within the dust collection monitoring chamber can be adjusted using the lifting action of the dust collection lifting transmission mechanism. Furthermore, the lateral position of the measuring base can be changed by manually adjusting the length of the dust collection telescopic linkage. Therefore, the first or second detection plate can be flexibly adjusted to the detection position according to different working conditions, and the height of the detection plates can also be flexibly adjusted. By mounting the first and second detection plates below the dust settling inlet on the measuring base, the likelihood of dust spreading to other areas during monitoring operations is effectively reduced. This ensures that all dust falling into the dust settling inlet is deposited on either the first or second detection plate, thus guaranteeing the monitoring effect and accuracy of the deposited dust. A self-cleaning unit is installed below the measuring base, allowing for convenient simultaneous cleaning of the lower detection plate when one is in the upper position. This effectively cleans the dust deposited on the used detection plate, preparing it for the next dust monitoring session. This alternating use of the two detection plates ensures continuous measurement of deposited dust in the work area. Installing the dust collection cylinder on a dust mass balance facilitates the centralized collection of falling dust. It also allows for real-time online weighing of the collected dust, enabling the determination of dust levels in the cylinder based on the weighing data. This allows for timely alerts and warnings to clean the cylinder when dust levels are high. A rotating disc is installed at the top of the dust collection cylinder, with a material discharge channel at its center. This ensures that dust falling during the cleaning of the testing plates can fall unimpeded into the dust collection cylinder, effectively ensuring centralized dust collection.A cleaning device and a spraying device are installed at opposite ends of the rotating disk. This design facilitates effective cleaning through the coordinated action of the cleaning and spraying devices, while also improving cleaning efficiency through the rotation of the disk. Furthermore, it ensures that the spraying and cleaning devices effectively cover the entire surface of the test piece, guaranteeing thorough cleaning of all parts and significantly increasing cleaning efficiency. The cleaning head is mounted on an electric telescopic cleaning rod, which is then installed on the upper end of the cleaning lifting transmission mechanism. This allows for lateral movement of the cleaning head using the electric telescopic cleaning rod and vertical movement using the cleaning lifting transmission mechanism. This enables flexible adjustment of the cleaning head's position relative to the test piece, facilitating comprehensive cleaning. The spray head has multiple spray outlets at both the end near the cleaning head and the top. When pressurized water is supplied, the multiple spray outlets near the cleaning head can spray mist-like droplets onto the cleaning head, thus wetting it and improving cleaning effectiveness and efficiency. Simultaneously, the multiple spray outlets at the top can also spray mist-like droplets onto the surface of the test piece to be cleaned, further wetting the surface and improving cleaning efficiency and effectiveness. The spray head is mounted on an electric telescopic spray rod, which is then mounted on the upper end of the spray lifting transmission mechanism. This allows for easy lateral movement of the spray head using the electric telescopic rod and vertical lifting of the spray head using the spray lifting transmission mechanism, enabling flexible movement according to different needs. The pressurized water supply component is connected to the spray head via a hose with an electrically controlled valve, ensuring a reliable supply of pressurized water and facilitating easy control of the spray head's start and stop. The adaptive identification module is connected to both the adaptive identification light group and the data processor. Simultaneously, the data processor is connected to both the first and second detection plates. This allows the data processor to control the adaptive identification light group to emit different lights based on different operating conditions when collecting dust quality data using either the first or second detection plate. This enables differentiated alarm actions for different conditions, effectively alerting personnel to take appropriate countermeasures based on the alarm type. The control terminal is configured for real-time communication with the data processor, allowing for real-time display of monitoring data and alarm information, facilitating more comprehensive and intelligent monitoring operations.

[0066] This system has the advantages of reasonable structure, low manufacturing cost, ideal real-time monitoring effect, excellent continuous monitoring performance and high monitoring efficiency. It can effectively improve the automation level of dust monitoring work, and can efficiently and accurately realize real-time, continuous and precise monitoring of dust in the workplace, significantly improving the safety of the working environment and providing strong technical support for the safety of industrial production.

[0067] This invention also provides a method for real-time monitoring of dust deposits in the workplace, employing a real-time dust deposit monitoring system in the workplace, comprising the following steps:

[0068] Step 1: Preparation;

[0069] First, place the real-time dust monitoring system in the workplace horizontally in the workplace to be tested, ensuring that the chamber cover 7 is closed during this process; then establish a communication connection between the control terminal 27 and the data processor 31.

[0070] Step 2: Record the initial empty weight;

[0071] Power is supplied by power module 30 to start the real-time dust monitoring system in the workplace. Before the monitoring operation begins, the data processor 31 receives the initial strain signals 1 and 2 from the first detection plate 9 and the second detection plate 10 respectively, and obtains the initial empty weight 1N-1 of the first detection plate 9 and the initial empty weight 2M-1 of the second detection plate 10 based on the initial strain signals 1 and 2. The data is then uploaded to the control terminal 27 through the communication module 29. The control terminal 27 receives the initial empty weight 1N-1 and the initial empty weight 2M-1 and records and displays them in real time.

[0072] Step 3: Conduct real-time continuous dust monitoring.

[0073] S1: Ensure that the first detection piece 9 is located in the detection position on the upper side; at the same time, send an opening signal to the motion control module 28 through the data processor 31. After receiving the opening signal, the motion control module 28 controls the electric hinge to rotate the chamber cover 7 to the open state, so that the dust monitoring chamber 8 can be connected to the external working environment through the dust settling port 6.

[0074] S2: Real-time monitoring of dust in the workplace is performed using the first detection element 9. The first detection element 9 receives dust in the environment in real time and sends the real-time strain signal 1 to the data processor 31. The data processor 31 obtains real-time strain data 1 based on the real-time strain signal 1 and matches it with real-time dust quality data 1. At the same time, the real-time dust quality data 1 is uploaded to the control terminal 27 through the communication module 29. The control terminal 27 receives the real-time dust quality data 1 and records and displays it in real time.

[0075] If the real-time dust quality data does not increase within a one-hour monitoring period, the data processor 31 sends a first-level alarm signal to the adaptive recognition module 26. After receiving the first-level alarm signal, the adaptive recognition module 26 controls the yellow alarm light in the adaptive recognition light group 25 to flash.

[0076] S3: After the single-sided monitoring time of the first detection plate 9 is reached, the dust deposited on the first detection plate 9 has reached its measurement limit. At this time, the data processor 31 obtains the stage dust quality data one and uploads it to the control terminal 27 through the communication module 29. After receiving the stage dust quality data one, the control terminal 27 records and displays it in real time. The data processor 31 sends a rotation action signal one to the motion control module 28. After receiving the rotation action signal one, the motion control module 28 controls the dust lifting transmission mechanism 13 to execute action one, so that the dust lifting transmission mechanism 13 drives the dust telescopic link 12 and the measuring base 11 to rotate 180 degrees, and drives the second detection plate 10 to rotate to the upper detection position.

[0077] S4: Real-time monitoring of dust in the workplace is performed using the second detection element 10. The second detection element 10 receives dust in the environment in real time and sends the real-time strain signal 2 to the data processor 31 to achieve continuous monitoring of dust deposits in the workplace. The data processor 31 obtains real-time strain data 2 based on the real-time strain signal 2, and matches the real-time dust quality data 2 based on the real-time strain data 2. At the same time, the real-time dust quality data 2 is uploaded to the control terminal 27 through the communication module 29. After receiving the real-time dust quality data 2, the control terminal 27 records and displays it in real time.

[0078] If the real-time dust quality data does not increase within a one-hour monitoring period, the data processor 31 sends a first-level alarm signal to the adaptive recognition module 26. After receiving the first-level alarm signal, the adaptive recognition module 26 controls the yellow alarm light in the adaptive recognition light group 25 to flash.

[0079] During the real-time monitoring of dust accumulation in the workplace via the second detection plate 10, the first detection plate 9 is simultaneously cleaned. A cleaning signal is sent from the data processor 31 to the motion control module 28. Upon receiving the cleaning signal, the motion control module 28 first controls the sweeping electric telescopic rod 20 to push the cleaning head 19 laterally towards the center of the measuring base 11, then controls the spraying electric telescopic rod 23 to push the spray head 22 laterally towards the center of the measuring base 11, and finally controls the electronically controlled valve to open, allowing the spray head to... Multiple spray outlets near the cleaning head 22 spray atomized droplets to wet the cleaning head 19. Simultaneously, multiple spray outlets at the upper end of the spray head 22 spray atomized droplets to wet the surface of the first detection plate 9. Next, the following control actions are performed sequentially: controlling the spray electric telescopic rod 23 to retract laterally to a fully retracted state; controlling the spray lifting transmission mechanism 24 to retract vertically to a fully retracted state; controlling the sweeping electric telescopic rod 20 to push the cleaning head 19 laterally below the right half of the measuring base 11; and controlling the sweeping lifting transmission mechanism 24... The moving mechanism 21 vertically pushes the cleaning head 19 to a position where it contacts the surface of the first detection plate 9; then, the rotating disk 14 is controlled to drive the sweeping device 15 and the spraying device 16 to start rotating at a uniform speed, while the electric telescopic sweeping rod 20 is controlled to drive the cleaning head 19 to move reciprocally in the lateral direction to ensure that the dust adhering to the first detection plate 9 is cleaned. At the same time, the falling dust falls into the dust collection cylinder 17 through the material drop channel in the center of the rotating disk 14; finally, after the set time for continuous sweeping, the sweeping operation is completed, and the sweeping is controlled to start rotating. The lifting transmission mechanism 21 retracts vertically to a fully retracted state, and then controls the sweeping electric telescopic rod 20 to retract horizontally to a fully retracted state to ensure that no interference occurs during the rotation of the measuring base 11. At the same time, the dust collection cylinder 17 completes the weighing of the fallen dust and sends the dust mass A1 to the data processor 31. After receiving the dust mass A1, the data processor 31 uploads it to the control terminal 27 through the communication module 29. After receiving the dust mass A1, the control terminal 27 records and displays it in real time.

[0080] S5: After the single-sided monitoring time of the second detection plate 10 is reached, the dust deposited on the second detection plate 10 has reached its measurement limit. At this time, the data processor 31 obtains the stage dust mass data 2 and uploads it to the control terminal 27 through the communication module 29. After receiving the stage dust mass data 2, the control terminal 27 records and displays it in real time. The data processor 31 sends a rotation action signal 2 to the motion control module 28. After receiving the rotation action signal 2, the motion control module 28 controls the dust falling rotation transmission mechanism 32 to execute action 2, so that the dust falling rotation transmission mechanism 32 drives the dust falling telescopic connecting rod 12 and the measuring base 11 to rotate 180 degrees, and drives the first detection plate 9 to rotate to the upper detection position. At the same time, the data processor 31 receives the updated strain signal 1 of the first detection plate 9 and obtains the updated empty weight 1N of the first detection plate 9 according to the updated strain signal 1, and then uploads it to the control terminal 27 through the communication module 29. The control terminal 27 receives the updated empty weight 1N and records and displays it in real time.

[0081] S6: Repeat S2 to perform real-time monitoring of dust in the workplace using the first detection element 9;

[0082] Simultaneously, during the real-time monitoring of dust accumulation in the work area by the first detection plate 9, the second detection plate 10 is cleaned. A second cleaning signal is sent from the data processor 31 to the motion control module 28. Upon receiving the second cleaning signal, the motion control module 28 first controls the electric sweeping telescopic rod 20 to push the cleaning head 19 laterally to a position close to the center of the measuring base 11, then controls the electric spray telescopic rod 23 to push the spray head 22 laterally to the center of the measuring base 11, and finally controls the electronically controlled valve to open, allowing the spray head to... Multiple spray outlets near the cleaning head 22 spray atomized droplets to wet the cleaning head 19. Simultaneously, multiple spray outlets at the upper end of the spray head 22 spray atomized droplets to wet the surface of the second detection plate 10. Next, the following control actions are performed sequentially: controlling the spray electric telescopic rod 23 to retract laterally to a fully retracted state; controlling the spray lifting transmission mechanism 24 to retract vertically to a fully retracted state; controlling the sweeping electric telescopic rod 20 to push the cleaning head 19 laterally below the right half of the measuring base 11; and controlling the sweeping lifting transmission mechanism... The moving mechanism 21 vertically pushes the cleaning head 19 to a position where it contacts the surface of the second detection plate 10; then, the rotating disk 14 is controlled to drive the sweeping device 15 and the spraying device 16 to start rotating at a constant speed, while the electric telescopic sweeping rod 20 is controlled to drive the cleaning head 19 to move reciprocally in the lateral direction to ensure that the dust adhering to the second detection plate 10 is cleaned. At the same time, the falling dust falls into the dust collection cylinder 17 through the material drop channel in the center of the rotating disk 14; finally, after the set time for continuous sweeping, the sweeping operation is completed, and the cleaning head is then controlled to move back to its original position. The sweeping lifting transmission mechanism 21 retracts vertically to a fully retracted state, and then controls the sweeping electric telescopic rod 20 to retract horizontally to a fully retracted state to ensure that no interference occurs during the rotation of the measuring base 11. At the same time, the dust collection cylinder 17 completes the weighing of the fallen dust and sends the dust mass A2 to the data processor 31. After receiving the dust mass A2, the data processor 31 uploads it to the control terminal 27 through the communication module 29. After receiving the dust mass A2, the control terminal 27 records and displays it in real time.

[0083] S7: Repeat S3; at the same time, receive the updated strain signal 2 of the second detection plate 10 through the data processor 31, obtain the updated empty weight 2M of the second detection plate 10 according to the updated strain signal 2, and then upload it to the control terminal 27 through the communication module 29. The control terminal 27 receives the updated empty weight 2M and records and displays it in real time.

[0084] S8: Repeat S4 and S5. At the same time, the data processor 31 receives the updated strain signal 2 from the first detection piece 9 and obtains the updated empty weight 1N+1 of the first detection piece 9 based on the updated strain signal 2. Then, it is uploaded to the control terminal 27 through the communication module 29. The control terminal 27 receives the updated empty weight 1N+1 and records and displays it in real time.

[0085] If the difference between the three values ​​N, N-1, and N+1 is less than 10%, it is determined that the first detection piece 9 can still be used normally, and S9 continues; if the difference between the three values ​​N, N-1, and N+1 is greater than or equal to 10%, it is determined that spraying and wiping alone cannot thoroughly clean it or the detection piece has been severely worn and needs to be replaced. At this time, the data processor 31 sends a secondary alarm signal to the adaptive recognition module 26. After receiving the secondary alarm signal, the adaptive recognition module 26 controls the red alarm light in the adaptive recognition light group 25 to flash. At the same time, the data processor 31 sends a stop signal to the motion control module 28. After receiving the stop signal, the motion control module 28 controls each component to stop moving and directly executes step four.

[0086] S9: Repeat S6 and S7, and obtain the updated empty weight 2M+1 during the execution of S7, and then upload it to the control terminal 27 through the communication module 29. The control terminal 27 receives the updated empty weight 2M+1 and records and displays it in real time.

[0087] If the difference between the three values ​​M, M-1, and M+1 is less than 10%, the second detection piece is considered to still be usable, and S10 continues. If the difference between the three values ​​M, M-1, and M+1 is greater than or equal to 10%, it is determined that spraying and wiping alone are insufficient to thoroughly clean the piece or that the detection piece is severely worn and needs to be replaced. In this case, the data processor 31 sends a secondary alarm signal to the adaptive recognition module 26. Upon receiving the secondary alarm signal, the adaptive recognition module 26 controls the red alarm light in the adaptive recognition light group 25 to flash. At the same time, the data processor 31 sends a stop signal to the motion control module 28. Upon receiving the stop signal, the motion control module 28 controls all components to stop moving and directly executes step four.

[0088] S10: Repeat S4 to S9 multiple times. At the same time, when executing S8, use the latest obtained values ​​of N, N-1, and N+1 to determine whether the first detection piece 9 can be used normally. When executing S9, use the latest obtained values ​​of M, M-1, and M+1 to determine whether the second detection piece 10 can be used normally, until the real-time continuous monitoring of the dust deposited in the work area is completed.

[0089] Step 4: End the monitoring operation;

[0090] The control power module 30 disconnects the power supply to each electrical device, thus ending the monitoring operation.

[0091] As a preferred embodiment, in step two, the first detection piece 9 is ensured to be in the upper detection position. If the first detection piece 9 is in the lower position, the data processor 31 sends a rotation action signal three to the motion control module 28. After receiving the rotation action signal three, the motion control module 28 controls the dust-falling rotation transmission mechanism 32 to execute action three, so that the dust-falling rotation transmission mechanism 32 drives the dust-falling telescopic connecting rod 12 and the measuring base 11 to rotate by a set angle, thereby driving the first detection piece 9 to rotate to the upper detection position.

[0092] To facilitate timely cleaning of the dust collection cylinder when it is filled with a large amount of dust, and to avoid affecting the accuracy of monitoring data due to excessive dust in the dust collection cylinder, in steps S8, S9, and S10 of step three, when the accumulated dust mass exceeds the maximum threshold, the data processor 31 sends a cleaning cylinder signal to the adaptive identification module 26. Upon receiving the cleaning cylinder signal, the adaptive identification module 26 controls the orange alarm light in the adaptive identification light group 25 to flash. At the same time, the data processor 31 sends a stop signal to the motion control module 28. After receiving the stop signal, the motion control module 28 controls all components to stop moving and sends a cleaning cylinder reminder message to the control terminal 27 through the communication module 29. The control terminal 27 receives the cleaning cylinder reminder message and displays it in real time.

[0093] This invention boasts a high degree of intelligence, eliminating the need for manual intervention throughout the monitoring process. This reduces labor intensity while effectively ensuring monitoring accuracy. The method automatically performs real-time, continuous, and precise detection of dust quality within the target space, significantly improving the accuracy and convenience of dust monitoring. Furthermore, it offers ideal monitoring results and high precision for deposited dust, effectively addressing the shortcomings of existing workplace dust monitoring methods. This provides reliable technical support for dust control and occupational health protection, and also offers strong technical support for safe management of the work environment.
