Description

Technical Field

[0001] The present application relates to the technical field of air purification, and in particular to a circulation purification control method and system for a clean room. Background Art

[0002] With the rapid development of science and technology, especially in cutting-edge technology fields such as semiconductor manufacturing and biomedicine, the requirements for the working environment are becoming more and more stringent, especially the demand for air cleanliness has shown a significant growth trend. Traditional air purification mechanisms often rely on the continuous introduction of external fresh air to maintain indoor air quality. This practice not only greatly increases energy consumption, but also has limitations in ensuring the stability and consistency of air quality.

[0003] The air purification equipment currently circulating on the market mainly covers two categories: HEPA high-efficiency particulate air filters and activated carbon adsorption devices. Specifically, HEPA filters, with their excellent filtering performance, can efficiently capture particles with a diameter greater than 0.3 microns in the air, showing a strong ability to remove particles. The activated carbon adsorption device is mainly dedicated to the adsorption treatment of gaseous pollutants, using the adsorption characteristics of activated carbon to effectively remove harmful gas components in the air. Although these devices can operate independently or in combination to improve the air purification effect, they can only rely on a fixed method when filtering, resulting in poor purification efficiency.

[0004] Therefore, there is an urgent need for a clean room circulation purification control method and system that can solve the above technical problems. Summary of the invention

[0005] The present application provides a circulation purification control method and system for a clean room. The method intelligently monitors the air quality of a target area. When the air quality does not meet the standard, the circulation purification mode is automatically started to continuously purify the target area, ensuring that the air quality of each clean room can be reasonably controlled. This effectively solves the problem of poor purification efficiency when currently using HEPA high-efficiency particulate air filters and activated carbon adsorption devices for air filtration.

[0006] In a first aspect, the present application provides a cyclic purification control method for a clean room, which is applied to a control platform, and the method includes: obtaining a target image corresponding to a target area, where the target area is an area corresponding to any clean room; determining the number of target personnel based on the target image; judging whether the number of target personnel is less than or equal to a preset number of personnel, where the preset number of personnel is set based on the area of ​​the target area; when the number of target personnel is greater than the preset number of personnel, confirming the acquisition of first monitoring data corresponding to the target area; when the first monitoring data is inconsistent with the preset monitoring data, confirming that the target area is in a state to be purified, and controlling the start of a cyclic purification mode according to the state to be purified, so as to purify the target area according to the cyclic purification mode.

[0007] By adopting the above technical solution, the target image corresponding to the target area is obtained, and the number of target personnel is determined, so that the dynamics of personnel in the clean room can be monitored in real time. When the number of target personnel is greater than the preset number of personnel, the first monitoring data of the target area is confirmed to be obtained, and dynamic monitoring of the air quality is realized. When the first monitoring data is inconsistent with the preset monitoring data, that is, the air quality does not meet the standard, it is automatically confirmed that the target area is in a state to be purified, and the cycle purification mode is controlled to start, and the target area is continuously purified until the air quality meets the standard. The purification mechanism is dynamically adjusted to ensure the continuous optimization and improvement of the purification efficiency, which effectively solves the problem of poor purification efficiency when using HEPA high-efficiency particulate air filters and activated carbon adsorption devices for air filtration.

[0008] Optionally, when the first monitoring data is inconsistent with the preset monitoring data, confirming that the target area is in a state to be purified specifically includes: obtaining a target quantity and target data from the first monitoring data, the target quantity includes the number of particles and the number of microorganisms, and the target data includes temperature data, humidity data, and air flow rate data; judging whether the target quantity is less than or equal to the preset quantity, and whether the target data is consistent with the preset data; when the target quantity is greater than the preset quantity, and the target data is inconsistent with the preset data, confirming that the target area is in a state to be purified.

[0009] By adopting the above technical solution, the number of particles, the number of microorganisms, temperature data, humidity data and air flow rate data are obtained from the first monitoring data to realize comprehensive monitoring of the air quality in the clean room. By comparing the target number (number of particles and number of microorganisms) with the preset number, as well as the target data (temperature data, humidity data, air flow rate data) with the preset data, it is possible to accurately determine whether the clean room needs to be purified. Only when the number of particles and the number of microorganisms exceed the standard, and parameters such as temperature, humidity or air flow rate do not meet the preset standards, will it be confirmed that the target area is in a state to be purified, thereby avoiding unnecessary purification operations and improving purification efficiency.

[0010] Optionally, after determining whether the target number is less than or equal to the preset number and whether the target data is consistent with the preset data, the method further includes: when the target number is less than or equal to the preset number and the target data is consistent with the preset data, confirming that the target area is in a normal state.

[0011] By adopting the above technical solution and comparing the target quantity (such as the number of particles and the number of microorganisms) with the target preset quantity, as well as the target data (such as temperature, humidity, and air flow rate) with the preset data, it is possible to accurately evaluate whether the air quality of the clean room is in a normal state. This evaluation method is based on the comparison between the actual monitoring data and the preset standards, which ensures the objectivity and accuracy of the evaluation results. When the air quality of the clean room is in a normal state, unnecessary purification operations can be avoided, thereby optimizing the operating time and energy consumption of the purification equipment.

[0012] Optionally, the start of the circulation purification mode is controlled according to the state to be purified, so that the target area is purified according to the circulation purification mode, specifically including: confirming the introduction of the air to be treated, heating the air to be treated, and obtaining the first air; performing the first-stage filtration on the first air to obtain the second air, and the first-stage filtration is used to filter the particles larger than the first target diameter in the first air; performing the second-stage filtration on the second air to obtain the third air, and the second-stage filtration includes filtering, disinfecting, and temperature and humidity adjustment, and the second-stage filtration is used to filter and remove the particles larger than the second target diameter in the second air, and the first target diameter is larger than the second target diameter; performing the third-stage filtration on the third air to obtain the fourth air, and the third-stage filtration is used to filter the particles larger than the third target diameter in the third air, and controlling the target blower to send the fourth air into the target area, and the second target diameter is larger than the third target diameter.

[0013] By adopting the above technical solution, the treated air is filtered in the first, second and third stages to gradually remove particulate pollutants in the air. At this time, the first stage of filtration removes large particles, the second stage of filtration further removes smaller particles and performs disinfection and temperature and humidity adjustment, and the third stage of filtration performs fine filtration on tiny particles again. This multi-stage filtration mechanism can ensure that particulate pollutants in the air are effectively removed and improve air cleanliness. The air that has been filtered and treated with temperature and humidity adjustment at the third stage is then sent into the target area through the target blower to ensure the stable and reliable air supply effect and avoid problems such as insufficient or uneven air supply.

[0014] Optionally, before confirming the introduction of the air to be treated, the method also includes: obtaining application requirements of the target area, determining the source of air according to the application requirements, the source of air including external air and exhaust gas, the external air is new air introduced from outside the target area, and the exhaust gas is air discharged from the exhaust port of the target area; determining an air valve to be opened according to the air source, the air valve including a first valve for controlling the entry of external air or a second valve for controlling the entry of exhaust gas.

[0015] By adopting the above technical solution, the specific application requirements of the target area are obtained, which include requirements for air quality, temperature and humidity, air flow speed, etc.; the air source is selected according to the application requirements, and the opening and closing of the first valve and the second valve are controlled, so that the air flow in the target area can be flexibly adjusted. When new air needs to be introduced, the first valve is opened, and the external air is sent to the target area after necessary filtration and adjustment, which helps to maintain the freshness and cleanliness of the air. When exhaust gas needs to be used, the second valve is opened, and the exhaust gas is sent to the target area after proper treatment, which helps to achieve resource reuse and energy conservation and emission reduction. The opening and closing of the air valve can be intelligently controlled according to actual needs, avoiding unnecessary energy waste.

[0016] Optionally, after controlling the start of the cyclic purification mode according to the state to be purified so as to purify the target area according to the cyclic purification mode, the method also includes: obtaining second monitoring data corresponding to the target area at a preset time interval; judging whether the second monitoring data is consistent with the preset monitoring data; when the second monitoring data is consistent with the preset monitoring data, confirming that the target area is in a normal purification state, determining treatment measures according to the normal purification state, and the treatment measures include measures to suspend the cyclic purification mode or measures to adjust the running time of the cyclic purification mode.

[0017] By adopting the above technical solution and obtaining the second monitoring data at preset intervals, the air quality status of the target area can be monitored in real time to ensure the timeliness and accuracy of the data. By comparing the second monitoring data with the preset monitoring data, it is possible to accurately determine whether the target area is in a normal purification state, providing a reliable basis for subsequent treatment measures. When the second monitoring data is consistent with the preset monitoring data, it is confirmed that the target area is in a normal purification state. At this time, measures can be taken to suspend the cycle purification mode to avoid unnecessary energy waste and equipment wear.

[0018] Optionally, the number of target persons is determined based on the target image, specifically including: acquiring a target image of the target area at a target time point; preprocessing the target image to obtain a preprocessed target image; using a target detection algorithm to identify the preprocessed target image to obtain target persons; counting the target persons to obtain the number of target persons.

[0019] By adopting the above technical solution, the target image of the target area at the target time point can be accurately obtained. The target image can be preprocessed, such as denoising, enhancing, cropping, etc., to optimize the image quality, reduce noise interference, and enhance image features, thereby improving the recognition efficiency and accuracy of the subsequent target detection algorithm. The target detection algorithm is used to identify the preprocessed target image, and the target person in the image can be accurately detected. The identified target person is counted to obtain the number of people in the target area at the target time point. The counting process can be completed automatically without manual intervention, which greatly improves the statistical efficiency and accuracy.

[0033] In order to enable technicians in this field to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments.

[0034] In the description of the embodiments of the present application, words such as "for example" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "for example" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "for example" or "for example" is intended to present related concepts in a specific way.

[0035] In the description of the embodiments of the present application, the meaning of the term "multiple" refers to two or more. For example, multiple systems refer to two or more systems, and multiple screen terminals refer to two or more screen terminals. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. The terms "include", "comprise", "have" and their variations all mean "including but not limited to", unless otherwise specifically emphasized.

[0036] With the rapid development of science and technology, especially in cutting-edge technology fields such as semiconductor manufacturing and biomedicine, the requirements for the working environment are becoming more and more stringent, especially the demand for air cleanliness has shown a significant growth trend. Traditional air purification mechanisms often rely on the continuous introduction of external fresh air to maintain indoor air quality. This practice not only greatly increases energy consumption, but also has limitations in ensuring the stability and consistency of air quality.

[0037] The air purification equipment currently circulating on the market mainly covers two categories: HEPA high-efficiency particulate air filters and activated carbon adsorption devices. Specifically, HEPA filters, with their excellent filtering performance, can efficiently capture particles with a diameter greater than 0.3 microns in the air, showing a strong ability to remove particles. The activated carbon adsorption device is mainly dedicated to the adsorption treatment of gaseous pollutants, using the adsorption characteristics of activated carbon to effectively remove harmful gas components in the air. Although these devices can operate independently or in combination to improve the air purification effect, they can only rely on a fixed method when filtering, resulting in poor purification efficiency.

[0038] Therefore, how to solve the problem of poor purification efficiency when using HEPA high-efficiency particulate air filters and activated carbon adsorption devices for air filtration. The embodiment of the present application provides a circulation purification control method for a clean room, which is applied to a control platform. The control platform of the present application is a platform that provides air purification control for a clean room. Figure 1 is a flow chart of a clean room circulation purification control method provided in an embodiment of the present application, with reference to Figure 1 The method includes the following steps S101-S105.

[0039] S101: Acquire a target image corresponding to a target area, where the target area is an area corresponding to any clean room.

[0040] In the above S101, high-definition cameras are installed in various key areas of the clean room to ensure that all areas that need to be monitored are covered. The image data of the target area is collected in real time by the camera, which usually involves the processing of the video stream and can be achieved through video processing software or hardware modules. According to actual needs, an image at a specific time point is selected as the target image, which is used to represent the image of the current area status. Clean rooms refer to operating rooms, laboratories, and manufacturing workshops.

[0041] S102: Determine the number of target persons according to the target image.

[0042] In the above S102, the number of target persons is determined based on the target image, which specifically includes: obtaining a target image of the target area at the target time point; preprocessing the target image to obtain a preprocessed target image; using a target detection algorithm to identify the preprocessed target image to obtain a target person; counting the target persons to obtain the number of target persons.

[0043] Specifically, a certain time point or a specific time point is specified. An image acquisition device (such as a camera) is installed in the target area to ensure that the device can clearly capture the image in the target area. The device should have good stability and clarity to ensure the quality of the acquired image. At the target time point, the image of the target area is acquired through the image acquisition device. This can be achieved by manually triggering the acquisition or setting a timed acquisition. Use an image denoising algorithm to remove noise from the target image, such as Gaussian noise, salt and pepper noise, etc. This helps to improve the accuracy of subsequent target detection. Enhance the target image, such as increasing contrast and sharpening edges. This helps to make the target person more prominent in the image and facilitate subsequent target detection. According to actual needs, the target image is scaled to meet the input requirements of the target detection algorithm. According to actual needs and application scenarios, select a suitable target detection algorithm. Common target detection algorithms include feature-based methods (such as Haar features, HOG features, etc.), region-based methods (such as Selective Search, EdgeBoxes, etc.), and deep learning-based methods (such as R-CNN series, YOLO series, SSD, etc.). If a target detection algorithm based on deep learning is used, a large amount of labeled data needs to be used for training in advance, and the algorithm needs to be tuned to improve its detection accuracy and robustness. Input the preprocessed target image into the target detection algorithm to identify the target person. The algorithm will output the location information (such as bounding box) of the target person in the image and the corresponding category label. Process the bounding box of each target person output by the target detection algorithm, remove overlapping or redundant bounding boxes, and ensure that each target person is counted only once. Use the counting algorithm to count the processed bounding boxes to obtain the number of target persons. This can be achieved by traversing the bounding box list and counting their number. Output the counting result as the number of target persons. At this time, the number of target persons refers to the number of all persons detected in the target area at the target time point. By implementing the above steps, the number of people in the target area at the target time point can be accurately counted.

[0044] S103: Determine whether the target number of personnel is less than or equal to a preset number of personnel, where the preset number of personnel is set based on the area of ​​the target area.

[0045] In the above S103, after determining the target number of personnel corresponding to the target time point in the target area, a reasonable upper limit of the number of personnel, i.e., the preset number of personnel, is pre-set based on factors such as the area, design capacity, and safety standards of the clean room. The target number of personnel is compared with the preset number of personnel to determine whether the number of personnel accommodated in the target area exceeds the limit. Due to the densely populated areas, the movement and operation of personnel will stir the indoor air and affect the air cleanliness, so more frequent monitoring and control of air quality is required to ensure the safety of personnel monitoring and working environment.

[0046] S104: When the number of target personnel is greater than the preset number of personnel, confirm to obtain the first monitoring data corresponding to the target area.

[0047] In the above S104, when the number of target personnel is greater than the preset number of personnel, other monitoring data in the target area needs to be obtained. Corresponding monitoring equipment is installed in the clean room, such as a particle counter, a microbial sampler, a temperature and humidity sensor, and an air flow meter. The environmental data of the target area is collected in real time through the monitoring equipment, including the number of particles, the number of microorganisms, temperature data, humidity data, and air flow rate data. The collected data are integrated to form a first monitoring data set.

[0048] S105: When the first monitoring data is inconsistent with the preset monitoring data, it is confirmed that the target area is in a state to be purified, and the cyclic purification mode is controlled to start according to the state to be purified, so as to purify the target area according to the cyclic purification mode.

[0049] In the above S105, when the first monitoring data is inconsistent with the preset monitoring data, confirming that the target area is in a state to be purified specifically includes: obtaining the target quantity and target data from the first monitoring data, the target quantity includes the number of particles and the number of microorganisms, and the target data includes temperature data, humidity data and air flow rate data; judging whether the target quantity is less than or equal to the preset quantity, and whether the target data is consistent with the preset data; when the target quantity is greater than the preset quantity, and the target data is inconsistent with the preset data, confirming that the target area is in a state to be purified. Specifically, by installing corresponding monitoring equipment in the clean room, and collecting environmental data of the target area in real time through the monitoring equipment, the environmental data includes the number of particles, the number of microorganisms, temperature data, humidity data and air flow rate data. Integrate the collected data to form a first monitoring data set. Based on the design requirements, industry standards or customer needs of the clean room, the upper limit values ​​of the number of particles and the number of microorganisms (i.e., the preset number), and the qualified ranges of temperature, humidity and air flow rate (i.e., the preset data) are preset. The target quantity and target data in the first monitoring data set are compared with the preset standard. For the target quantity, check whether it exceeds the upper limit of the preset quantity; for the target data, check whether it is within the qualified range of the preset data. According to the comparison results, judge whether the environmental conditions of the target area meet the preset standards. If the target quantity exceeds the upper limit of the preset quantity, and the target data is inconsistent with the preset data (that is, at least one data is out of the qualified range), proceed to the next step. When the target quantity exceeds the upper limit of the preset quantity, and the target data is inconsistent with the preset data, it is automatically confirmed that the target area is in the state of being purified. At this time, it is confirmed that the environmental conditions of the target area are poor and purification treatment is required.

[0050] In addition, when the target quantity is less than or equal to the preset quantity, and the target data is consistent with the preset data, it is confirmed that the target area is in a normal state. Specifically, the target quantity and target data at the current time point are extracted from the monitoring data set. The extracted target quantity and target data are compared with the preset standard. For the target quantity, check whether it is less than or equal to the upper limit of the preset quantity; for the target data, check whether it is completely within the qualified range of the preset data. According to the comparison result, if the target quantity is less than or equal to the preset quantity, and the target data is completely consistent with the preset data, proceed to the next step of processing. When the target quantity meets the preset quantity requirements, and the target data meets the preset data requirements, it is automatically confirmed that the target area is in a normal state. The above steps can realize real-time monitoring and intelligent judgment of the clean room environment. When the environmental data of the target area meets the preset standard, it is automatically confirmed that it is in a normal state, thereby ensuring that the clean room always maintains a good operating environment.

[0051] Further, after confirming that the target area is in a state to be purified, the purification equipment of the target area needs to be started to purify the air in the target area. The start of the circulation purification mode is controlled according to the state to be purified, so as to purify the target area according to the circulation purification mode, which specifically includes: confirming the introduction of the air to be treated, heating the air to be treated, and obtaining the first air; performing the first-stage filtration on the first air to obtain the second air, and the first-stage filtration is used to filter the particles larger than the first target diameter in the first air; performing the second-stage filtration on the second air to obtain the third air, and the second-stage filtration includes filtering, disinfection, and temperature and humidity adjustment, and the second-stage filtration is used to filter and remove the particles larger than the second target diameter in the second air, and the first target diameter is larger than the second target diameter; performing the third-stage filtration on the third air to obtain the fourth air, and the third-stage filtration is used to filter the particles larger than the third target diameter in the third air, and controlling the target blower to send the fourth air into the target area, and the second target diameter is larger than the third target diameter. Specifically, the air to be treated or the internal circulating air is introduced into the treatment process through the air introduction valve. Before the air is introduced, the air quality monitor can be used to conduct preliminary monitoring of the air quality to ensure that the introduced air quality meets the basic requirements. The air to be treated is heated by using an air heater (such as an electric heater, a steam heater, etc.). The output power of the heater is monitored and adjusted in real time through a temperature sensor and a control system so that the temperature of the heated air reaches a preset value. The air after the heating treatment is marked as the first air and enters the next level of filtration. The first level of filtration of the first air is performed by using a primary filter or a medium filter. Particles (such as dust, hair, fiber, etc.) larger than the first target diameter in the first air are removed by physical barriers. The first level of filtration is to protect the filter unit from damage and extend its service life. The air after the first level of filtration is marked as the second air and enters the next level of filtration. The second level of filtration of the second air includes filtration, disinfection, and temperature and humidity adjustment to further remove particles (such as bacteria, viruses, pollen, and smoke, etc.) larger than the second target diameter in the second air. The second target diameter is smaller than the first target diameter, and ultraviolet disinfection lamps are used to kill microorganisms in the air. According to the temperature and humidity requirements of the target area, the air is temperature-controlled and humidified by a humidification / dehumidification device. The air that has been filtered, disinfected, and temperature and humidity regulated in the second stage is marked as the third air and enters the next stage of filtering. Finally, the third air is filtered in the third stage, using an ultra-high efficiency filter (such as a HEPA filter) for the third stage. Particles larger than the third target diameter (such as bacteria, viruses, PM2.5, etc.) are removed from the third air. The third target diameter is smaller than the second target diameter, and the third target diameter is also smaller than the first target diameter, including some tiny viruses and bacteria.The air after the third-stage filtration is marked as the fourth air and is ready to be delivered to the target area. According to the area, height, ventilation requirements and other factors of the target area, select a suitable blower and install it. Design a reasonable air supply duct to ensure that the fourth air can be delivered to the target area evenly and efficiently. The control platform monitors the air quality, temperature and humidity and other parameters of the target area in real time, and adjusts the speed and air supply volume of the blower as needed to maintain the stability of the environment in the target area. The above steps are a complete purification process. After starting the purification process, the above purification process starts to circulate according to the set circulation purification mode so that the air in the target area can be continuously and effectively purified.

[0052] For example, the first target diameter may be set to particles of 2 mm, the second target diameter may be set to particles of 0.3 μm to 2 mm, and the third target diameter may be set to particles of 0.01 μm to 0.3 μm.

[0053] Furthermore, due to the different safety and hygiene requirements of different clean rooms, the air source needs to be determined according to the purpose of the target area to avoid the introduction of heavily polluted external air. Before confirming the introduction of the air to be treated, the application requirements of the target area are obtained, and the air source is determined according to the application requirements. The air source includes external air and exhaust gas. The external air is the new air introduced from outside the target area, and the exhaust gas is the air discharged from the exhaust port of the target area; the air valve to be opened is determined according to the air source. The air valve includes a first valve to control the entry of external air or a second valve to control the entry of exhaust gas. Specifically, a detailed investigation is conducted on the target area to understand its purpose of use, personnel activities, equipment configuration, production process, etc., so as to determine its specific requirements for air quality, temperature, humidity, etc. According to the survey results, the application requirements of the target area are analyzed to clarify its demand for new air and the requirements for the treatment of exhaust gas. If the target area needs to introduce new air to maintain indoor air quality, provide oxygen, or adjust temperature and humidity, etc., then select external air as the air source. External air is usually introduced through a fresh air system or natural ventilation outlet. If there is exhaust gas in the target area, and these exhaust gases meet the emission standards or can be recycled after treatment, the exhaust gas can be considered as part of the air source. This usually requires the installation of exhaust gas treatment devices at the exhaust port, such as dust collectors, desulfurization and denitrification devices, etc. According to the specific needs of the target area and the availability of external air and exhaust gas, the final air source is comprehensively judged and determined. In the ventilation system of the target area, a first valve for controlling the entry of external air and a second valve for controlling the entry of exhaust gas are configured. These valves can be pneumatic valves, electric valves or manual valves, and the specific selection depends on the actual situation. According to the determined air source, the corresponding valve is selected to open. If the main air is outside, open the first valve; if the main exhaust gas (and after treatment), open the second valve. In some cases, it may be necessary to open both valves at the same time to adjust the ratio of new air and exhaust gas. The opening and closing of the valve can be achieved by an automatic control system, or it can be manually controlled by the operator. The automatic control system usually automatically adjusts according to the parameters such as air quality, temperature and humidity in the target area to ensure the stability and comfort of the indoor environment. After determining the source of the air to be treated, the introduced air to be treated is purified according to the above purification process, and the filtered and purified air is sent into the target area, so that the air in the target area is continuously and effectively purified.

[0054] In a possible implementation, after the target area starts the cycle purification mode, the target area needs to be monitored periodically, and its purification state is judged according to the monitoring results, and then the corresponding treatment measures are determined. At a preset time interval, the second monitoring data corresponding to the target area is obtained; whether the second monitoring data is consistent with the preset monitoring data; when the second monitoring data is consistent with the preset monitoring data, it is confirmed that the target area is in a normal purification state, and the treatment measures are determined according to the normal purification state, and the treatment measures include measures to suspend the cycle purification mode or to adjust the running time of the cycle purification mode. Specifically, after determining to start the cycle purification mode for the target area, a reasonable preset time is set according to factors such as the purification requirements, environmental characteristics and equipment performance of the target area. This time can be a fixed time interval, such as 1 hour or 6 hours, or it can be dynamically adjusted, and intelligently set according to historical monitoring data and purification effects. Corresponding monitoring equipment, such as air quality monitors, temperature and humidity sensors, etc., are deployed in or around the target area to obtain parameters such as air quality, temperature and humidity in the target area in real time or regularly. When the preset time is reached, the monitoring equipment is automatically or manually triggered to obtain the second monitoring data corresponding to the target area. These data should cover all parameters that need to be monitored to ensure a comprehensive assessment of the purification status of the target area. Before starting, a set of preset monitoring data is set according to factors such as the purification standard, industry standard or user needs of the target area. These data should clearly define the normal range or target value of each monitoring parameter. Compare the acquired second monitoring data with the preset monitoring data to determine whether they are consistent. The consistency judgment can be set according to specific needs, such as allowing a certain error range or adopting strict matching standards. According to the comparison results, it is determined whether the target area is in a normal purification state. If the second monitoring data is consistent with the preset monitoring data or the error is within an acceptable range, the target area is considered to be in a normal purification state; otherwise, it is considered that the target area is still in a state to be purified, and the cycle purification mode continues to be controlled to purify the target area. When the second monitoring data is consistent with the preset monitoring data, it is automatically confirmed that the target area is in a normal purification state. If the target area has been in a normal purification state for a long time and the external environment is stable, you can consider suspending the cycle purification mode to save energy and reduce equipment wear. According to historical monitoring data and purification effects, the running time of the cycle purification mode is intelligently adjusted. For example, the number of cycles in the cyclic purification mode can be adjusted from 6 cycles per hour to 3 cycles per hour.
