Description

Technical Field

[0001] The present application relates to the technical field of air purification, and in particular to a PM2.5 purification method and system for a double-effect heat pump heated swimming pool. Background Art

[0002] Constant-temperature swimming pools are typically located indoors to minimize heat loss and the energy required to maintain the water temperature. To ensure acceptable water quality, chlorine-containing disinfectants are often added. Indoor swimming pools are also prone to moisture in the air, floors, and walls. However, the volatilization and residue of chlorine-containing disinfectants, the release of volatile organic compounds from finishing materials, and the presence of dust, particulate matter, and microbial spores can contribute to elevated PM2.5 levels in indoor pool air. Air quality is crucial to the health of those in constant-temperature swimming pools. The aforementioned related technologies suffer from the problem of elevated PM2.5 levels in indoor constant-temperature swimming pool environments. Summary of the Invention

[0003] In order to improve the purification efficiency of PM2.5 in the air of an indoor constant temperature swimming pool, the present application provides a PM2.5 purification method and system for a double-effect heat pump heated swimming pool.

[0004] The first object of the invention of this application is achieved by adopting the following technical solution:

[0005] PM2.5 purification method for double-effect heat pump heated swimming pool, including:

[0006] Based on the design drawings of the target swimming pool, a BIM model is created and input into a fluid simulation program to generate a twin model of the swimming pool. The monitoring locations of several sensors are marked in the twin model of the swimming pool.

[0007] Acquire a number of monitoring data in real time and load them into the pool twin model. Process the monitoring data based on the interpolation evaluation algorithm to calculate the fluid data of each fluid grid in the target pool.

[0008] Based on the PM2.5 concentration of each fluid grid, the corresponding pollution level is matched, and the overall pollution parameters and activity area pollution parameters are calculated based on the preset overall pollution evaluation formula and activity area pollution evaluation formula;

[0009] When the overall pollution parameter is greater than the preset overall pollution threshold, a pollution removal instruction is generated and sent to the pollution removal component; when the activity area pollution parameter is greater than the preset activity area pollution threshold, an air flow promotion instruction is generated and sent to the air flow promotion component;

[0010] The design drawings record the specifications of the target swimming pool; the monitoring data includes coordinate data, sampling time, and air parameters, where the air parameters include PM2.5 concentration; the indoor space of the target swimming pool is provided with a number of fluid grids for accommodating air; the fluid data includes coordinate data, evaluation time, and air parameters.

[0011] By adopting the above technical solution, a BIM model of the target swimming pool is created based on the design drawings of the target swimming pool to obtain the architectural space characteristics of the target swimming pool. The BIM model is then input into the fluid simulation model to generate a pool twin model and mark the monitoring positions of several sensors so that fluid phenomena such as air flow in the target swimming pool, water flow in the swimming pool, indoor and outdoor air heat exchange, and air and pool water heat exchange can be simulated based on the input monitoring data. Several monitoring data are acquired in real time and loaded into the pool twin model. Based on the coordinate data, sampling time, and corresponding air parameters or pool water parameters recorded in the monitoring data, the data is processed using the interpolation evaluation algorithm built into the pool twin model to calculate the fluid data of each fluid grid in the target swimming pool building. Based on the PM2.5 concentration of each fluid grid, the corresponding pollution level is matched, and the overall pollution parameters and activity area pollution parameters are calculated through the corresponding calculation formula to obtain the overall PM2.5 pollution situation in the target swimming pool building and the PM2.5 pollution situation in the main activity area of ​​​​people; when the overall pollution parameter is greater than the overall pollution threshold, a pollution removal instruction is generated and sent to the pollution removal component to control the pollution removal component to perform PM2.5 pollution removal work; when the activity area pollution parameter is greater than the activity area pollution threshold, an air flow promotion instruction is generated and sent to the air flow promotion component to control the air flow promotion component to drive the air flow in the main activity area of ​​​​people to disperse the high-density PM2.5 in the area, thereby improving the purification efficiency of PM2.5 in the air of indoor constant temperature swimming pools.

[0012] In a preferred example of the present application: the activity area pollution parameter is used to evaluate the pollution situation in the main activity area of ​​the target swimming pool, the main activity area of ​​the target swimming pool being the space below the activity height set above the water surface of the target swimming pool; each of the pollution levels is assigned a pollution level value that is positively correlated with the degree of pollution;

[0013] The overall pollution assessment formula is:

[0014]

[0015] The pollution assessment formula for the activity area is:

[0016]

[0017] Among them, Z A is the overall pollution parameter, Z Bis the pollution parameter of the activity area, i is the serial number of the fluid grid, the fluid grid number of the main activity area of ​​the personnel is before the fluid grid numbers of other areas, m is the number of fluid grids in the main activity area of ​​the personnel, n is the total number of fluid grids, P i is the PM2.5 concentration of fluid grid i, V i is the volume of fluid grid i, P Li Assign a value to the pollution level of fluid grid i, k h is the height influence coefficient negatively correlated with the height coordinate of the fluid grid, k hi is the height influence coefficient of fluid grid i.

[0018] By adopting the above technical solution, in order to reduce water temperature fluctuations, indoor constant temperature swimming pools usually need to maintain a stable indoor temperature and reduce air flow. PM2.5 in the air has a sedimentation effect, so the PM2.5 concentration in the main activity area of ​​personnel is usually higher than the overall PM2.5 concentration level in the room. Therefore, it is very important to evaluate the pollution situation in the main activity area of ​​personnel and the overall pollution situation in the room separately. The overall pollution parameter is calculated by summing the PM2.5 concentration of each fluid grid and the corresponding volume, and is used to determine the total amount of PM2.5 in the target swimming pool. The activity area pollution parameter is calculated by averaging the pollution level assignment of each fluid grid in the main activity area of ​​personnel and the weighted height influence coefficient. It is more helpful to reflect the pollution situation in the main activity area of ​​personnel. Replacing PM2.5 concentration in the calculation by pollution level assignment also helps to simplify the computer resources required for the calculation.

[0019] In a preferred embodiment of the present application, before calculating the overall pollution parameters and the activity area pollution parameters based on the preset overall pollution evaluation formula and the activity area pollution evaluation formula, the following steps are included:

[0020] Obtain surveillance images of the target swimming pool, identify the activity postures of each person based on the surveillance images, and calculate the proportion of people corresponding to each activity posture;

[0021] Calculate and update the activity height based on the personnel ratio corresponding to each activity posture and a preset activity evaluation formula;

[0022] The activity evaluation formula is:

[0023] H B =H e R e +H f R f +H g R g

[0024] The activity postures include swimming, squatting, and standing; R e is the proportion of swimmers, Rf is the proportion of squatting people, R g is the proportion of standing personnel, H e The altitude for swimming breathing is simulated, H f Design height for squat breathing, H g Designed height for standing breathing.

[0025] By adopting the above-mentioned technical solution, the surveillance image of the target swimming pool is obtained, the activity postures of each person in the target swimming pool building are identified from the surveillance image, and the corresponding personnel ratio is calculated according to the number of people in each activity posture and the total number of people, so as to facilitate the subsequent setting of the activity height according to the ratio of people in different activity postures; because the air inhaled by people in different activity postures comes from different heights in the target swimming pool building space, the corresponding activity height is calculated and updated according to the real-time ratio of people in each activity posture and the preset activity evaluation formula, wherein the activity height is determined by weighted summation of the ratio of people in different activity postures and the corresponding simulated breathing height, so as to improve the rationality of the activity height setting.

[0026] In a preferred embodiment of the present application, after obtaining the surveillance image of the target swimming pool and identifying the activity postures of each person based on the surveillance image, the method further includes:

[0027] The activity speed of each person is detected through an image ranging algorithm, and the activity intensity assessment value is calculated based on the activity posture, activity speed and a preset activity intensity assessment formula of each person; the corresponding activity zone pollution threshold is matched and updated based on the activity intensity assessment value;

[0028] The image ranging algorithm is an algorithm used to detect the distance between two points in an image and to detect the speed of an object based on the time axis of the image;

[0029] The activity intensity evaluation formula is:

[0030]

[0031] Among them, Y0 is the activity intensity assessment value, j is the person identifier, x is the number of people in the target swimming pool building, k Tj is the posture coefficient of person j, and the value of the posture coefficient is associated with the activity posture of the corresponding person; each activity area pollution threshold corresponds to an activity intensity assessment value interval, and the activity area pollution threshold is negatively correlated with the corresponding activity intensity assessment value.

[0032] By adopting the technical scheme, the greater the movement intensity of the human body is, the more air needs to be inhaled, and the greater the influence of air pollutants is. Therefore, the image ranging algorithm is used to detect the moving speed of each person, and the activity intensity evaluation value is calculated by combining the corresponding activity posture of each person and the activity intensity evaluation formula, so as to obtain the overall activity intensity of all the people in the target swimming pool building. The activity intensity evaluation value is matched and updated to the corresponding activity area pollution threshold value, so that the activity area pollution threshold value is set according to the overall activity intensity of all the people in the target swimming pool, thereby improving the rationality of setting the air quality requirement of the main activity area of the people.

[0033] In a preferred example of the present application, the air parameters further include air humidity;

[0034] After calculating the overall pollution parameter and the activity area pollution parameter, the following steps are further included:

[0035] Based on the air humidity of each fluid grid, the corresponding humidity level is matched, and the activity area humidity parameter is calculated based on a preset activity area humidity evaluation formula;

[0036] When the activity area humidity parameter is greater than a preset activity area humidity threshold value or the overall pollution parameter is greater than a preset overall pollution threshold value, a decontamination instruction is generated and sent to the decontamination component;

[0037] The decontamination component includes a fan for driving air flow, a double-effect heat pump dryer for drying air, and an air purifier for purifying PM2.5.

[0038] By adopting the technical scheme, the higher the air humidity is, the more difficult it is for the moving person to breathe, thereby affecting the movement performance of the swimmer. Therefore, based on the air humidity of each fluid grid, the corresponding humidity level is matched, and the activity area humidity parameter is calculated by the activity area humidity evaluation formula, so as to obtain the air humidity condition of the main activity area of the people. Since the PM2.5 purification efficiency of dry air is higher, and simultaneously performing drying treatment and PM2.5 purification treatment helps to reduce the working frequency of the fan, when the activity area humidity parameter is greater than the activity area humidity threshold value, or the overall pollution parameter is greater than the preset overall pollution threshold value, a decontamination instruction is generated and sent to the decontamination component, so as to control the fan to drive the air flow in the main activity area of the people to the double-effect heat pump dryer and the air purifier, so that the double-effect heat pump dryer performs drying treatment on the air, and the air purifier performs PM2.5 purification treatment on the dried air, thereby optimizing the purification efficiency of PM2.5 and excessive moisture in the air of the indoor constant-temperature swimming pool.

[0039] The second purpose of the present application is achieved by the following technical scheme:

[0041] The pool twin model creation module is used to create a BIM model based on the design drawings of the target pool and input it into the fluid simulation program to generate a pool twin model. The monitoring locations of several sensors are marked in the pool twin model.

[0042] The fluid data calculation module is used to obtain a number of monitoring data in real time and load it into the pool twin model. The module processes the monitoring data based on the interpolation evaluation algorithm to calculate the fluid data of each fluid grid in the target pool.

[0043] The pollution analysis module is used to match the PM2.5 concentration of each fluid grid with the corresponding pollution level, and calculate the overall pollution parameters and activity zone pollution parameters based on the preset overall pollution evaluation formula and activity zone pollution evaluation formula;

[0049] The activity evaluation formula is:

[0050] H B =H e R e +H f R f +H g R g

[0051] The activity postures include swimming, squatting, and standing; R e is the proportion of swimmers, R f is the proportion of squatting people, R g is the proportion of standing personnel, H e The altitude for swimming breathing is simulated, H f Design height for squat breathing, H g Designed height for standing breathing.

[0052] In a preferred example of the present application, the activity posture analysis submodule includes:

[0053] The activity intensity assessment submodule is used to detect the activity speed of each person through an image ranging algorithm, and calculate the activity intensity assessment value based on the activity posture, activity speed and a preset activity intensity assessment formula of each person;

[0054] An activity zone pollution threshold updating submodule is used to match and update the corresponding activity zone pollution threshold based on the activity intensity evaluation value;

[0055] The image ranging algorithm is an algorithm used to detect the distance between two points in an image and to detect the speed of an object based on the time axis of the image;

[0062] A computer-readable storage medium stores a computer program, which, when executed by a processor, implements the steps of the PM2.5 purification method for a swimming pool heated by a double-effect heat pump.

[0063] In summary, this application includes at least one of the following beneficial technical effects:

[0064] 1. Based on the design drawings of the target swimming pool, create a BIM model of the target swimming pool to obtain the architectural space characteristics of the target swimming pool, input the BIM model into the fluid simulation model, generate a pool twin model and mark the monitoring positions of several sensors, so that the air flow in the target swimming pool, the water flow in the swimming pool, the indoor and outdoor air heat exchange, the air and water heat exchange in the swimming pool and other fluid phenomena can be simulated based on the input monitoring data; obtain a number of monitoring data in real time and load them into the pool twin model, based on the coordinate data, sampling time, and corresponding air parameters or pool water parameters recorded by the monitoring data, process them through the built-in interpolation evaluation algorithm of the pool twin model to calculate the fluid data of each fluid grid in the target swimming pool building; based on each fluid The PM2.5 concentration of the grid is matched with the corresponding pollution level, and the overall pollution parameters and activity area pollution parameters are calculated through the corresponding calculation formula to obtain the overall PM2.5 pollution situation in the target swimming pool building and the PM2.5 pollution situation in the main activity area of ​​​​people; when the overall pollution parameter is greater than the overall pollution threshold, a pollution removal instruction is generated and sent to the pollution removal component to control the pollution removal component to perform PM2.5 pollution removal work; when the activity area pollution parameter is greater than the activity area pollution threshold, an air flow promotion instruction is generated and sent to the air flow promotion component to control the air flow promotion component to drive the air flow in the main activity area of ​​​​people to disperse the high-density PM2.5 in the area, thereby improving the purification efficiency of PM2.5 in the air of the indoor constant temperature swimming pool.

[0065] 2. Indoor constant-temperature swimming pools typically require maintaining a stable indoor temperature and reducing air flow to minimize water temperature fluctuations. PM2.5 in the air has a settling effect, so PM2.5 concentrations in primary activity areas are typically higher than the overall indoor PM2.5 concentration. Therefore, it is crucial to separately assess pollution levels in primary activity areas and overall indoor pollution. The overall pollution parameter is calculated by multiplying the PM2.5 concentration of each fluid grid by its corresponding volume and is used to determine the total amount of PM2.5 in the target pool. The activity zone pollution parameter is calculated by taking the average of the pollution level assigned to each fluid grid in the primary activity area and the weighted average of the height influence coefficient. This more effectively reflects pollution levels in primary activity areas. Replacing PM2.5 concentrations with pollution level assignments also helps simplify the computational resources required.

[0070] The following will be combined with the drawings Figures 1 to 3 The present application will be further described in detail.

[0071] Embodiment one

[0072] Referring to Figure 1 , the present application discloses a PM2.5 purification method of a double-effect heat pump heated swimming pool, which specifically comprises the following steps:

[0073] S10: based on the design drawing of the target swimming pool, create a BIM model and input it into a fluid simulation program to generate a swimming pool twin model, and mark the monitoring positions of a plurality of sensors in the swimming pool twin model.

[0074] In the present embodiment, the design drawing records the specification parameters of the target swimming pool, and the sensors are used to detect air parameters.

[0075] Specifically, based on the design drawing of the target swimming pool, a BIM model of the target swimming pool is created to obtain the architectural space features of the target swimming pool, the BIM model is input into a fluid simulation model to generate a swimming pool twin model and mark the monitoring positions of a plurality of sensors, so as to subsequently simulate fluid phenomena such as air flow in the target swimming pool, water flow in the swimming pool, indoor and outdoor air heat exchange, air and swimming pool water heat exchange, etc. based on the input monitoring data.

[0076] S20: Acquire a number of monitoring data in real time and load them into the swimming pool twin model, process the monitoring data based on the interpolation evaluation algorithm to calculate the fluid data of each fluid grid in the target swimming pool.

[0077] In this embodiment, the monitoring data includes coordinate data, sampling time, and air parameters, where the air parameters include PM2.5 concentration; the indoor space of the target swimming pool is provided with a number of fluid grids for accommodating air; the fluid data includes coordinate data, evaluation time, and air parameters.

[0078] Specifically, a number of monitoring data are acquired in real time and loaded into the swimming pool twin model. Based on the coordinate data, sampling time, and corresponding air parameters or pool water parameters recorded in the monitoring data, they are processed through the interpolation evaluation algorithm built into the swimming pool twin model to calculate the fluid data of each fluid grid in the target swimming pool building.

[0079] S30: Based on the PM2.5 concentration of each fluid grid, the corresponding pollution level is matched, and based on the preset overall pollution evaluation formula and activity area pollution evaluation formula, the overall pollution parameters and activity area pollution parameters are calculated.

[0080] Specifically, based on the PM2.5 concentration of each fluid grid, the corresponding pollution level is matched, and the overall pollution parameters and activity area pollution parameters are calculated using the corresponding calculation formulas, so as to understand the overall PM2.5 pollution situation in the target swimming pool building and the PM2.5 pollution situation in the main activity areas of personnel.

[0081] In this embodiment, the activity zone pollution parameter is used to assess the pollution level of the main activity area of ​​the target swimming pool. The main activity area refers to the space below the activity height set above the water surface of the target swimming pool within the target swimming pool building. Each pollution level is assigned a pollution level value that is positively correlated with the degree of pollution. The number of pollution levels can be set according to actual needs.

[0082] The overall pollution assessment formula is:

[0083]

[0084] The pollution assessment formula for the activity area is:

[0085]

[0086] Among them, Z A is the overall pollution parameter, Z Bis the pollution parameter of the activity area, i is the serial number identifier of the fluid grid, and all parameters, data, etc. with the identifier as the subscript involved in this embodiment refer to the parameters, data, etc. corresponding to the identifier; the serial number of the fluid grid in the main activity area of ​​the personnel is before the serial number of the fluid grid in other areas. Preferably, the serial number assignment method of the fluid grid is set to sort from low to high by height coordinate; m is the number of fluid grids in the main activity area of ​​the personnel, n is the total number of fluid grids, n>m, P i is the PM2.5 concentration of fluid grid i, V i is the volume of fluid grid i. Preferably, when the volume of the fluid grid is small, the sizes of all fluid grids can be regarded as the same to simplify the calculation; P Li Assign a value to the pollution level of fluid grid i, k h is the height influence coefficient negatively correlated with the height coordinate of the fluid grid, k hi is the height influence coefficient of fluid grid i.

[0087] In order to reduce water temperature fluctuations, indoor constant-temperature swimming pools usually need to maintain a stable indoor temperature and reduce air flow. PM2.5 in the air has a sedimentation effect, so the PM2.5 concentration in the main activity area of ​​​​people is usually higher than the overall PM2.5 concentration level in the room. Therefore, it is very important to evaluate the pollution situation in the main activity area of ​​​​people and the overall pollution situation indoors separately. The overall pollution parameter is calculated by summing the PM2.5 concentration of each fluid grid and the corresponding volume, and is used to determine the total amount of PM2.5 in the target swimming pool. The activity area pollution parameter is calculated by averaging the pollution level assignment and the height influence coefficient of each fluid grid in the main activity area of ​​​​people. It is more helpful to reflect the pollution situation in the main activity area of ​​​​people. Replacing PM2.5 concentration in the calculation by pollution level assignment also helps to simplify the computer resources required for the calculation.

[0088] Before the step of calculating the overall pollution parameters and the activity area pollution parameters based on the preset overall pollution evaluation formula and the activity area pollution evaluation formula in S30, the following steps are included:

[0089] S31: Obtain surveillance images of the target swimming pool, identify the activity postures of each person based on the surveillance images, and count the proportion of people corresponding to each activity posture.

[0090] In this embodiment, when identifying the activity postures of people, an existing algorithm may be used; the proportion of people in a specific activity posture refers to the proportion of people in the specific activity posture to the total number of people.

[0091] Specifically, surveillance images of the target swimming pool are obtained, and the activity postures of each person in the target swimming pool building are identified from the surveillance images. The corresponding personnel ratio is calculated based on the number of people in each activity posture and the total number of people, so as to facilitate the subsequent setting of the activity height according to the ratio of people in different activity postures.

[0092] S32: Calculate and update the activity height based on the personnel ratio corresponding to each activity posture and a preset activity evaluation formula.

[0093] In this embodiment, the activity evaluation formula is:

[0094] H B =H e R e +H f R f +H g R g

[0095] The activity postures include swimming, squatting, and standing. Preferably, the distinction between squatting and standing can be determined based on the height of the head relative to the ground corresponding to the current posture of the person. For example, people who are outside the water of a swimming pool and whose head height is higher than 1.2m from the ground are uniformly determined to be in a standing state, otherwise they are determined to be in a squatting state. People who are in the water of a swimming pool are uniformly determined to be in a swimming state; R e is the proportion of swimmers, R f is the proportion of squatting people, R g is the proportion of standing personnel, H e The altitude for swimming breathing is simulated, H f Design height for squat breathing, H g For the simulated height for standing breathing, preferably, the simulated height for swimming breathing, the simulated height for squatting breathing, and the simulated height for standing breathing can be set to 0.5, 1.0, and 1.5m, respectively.

[0096] Specifically, since the air inhaled by people in different activity postures comes from different heights within the target swimming pool building space, the corresponding activity height is calculated and updated based on the real-time proportion of people in each activity posture and the preset activity evaluation formula, where the activity height is determined by weighted summation of the proportion of people in different activity postures and the corresponding simulated breathing height, so as to improve the rationality of the activity height setting.

[0097] After the step of obtaining a surveillance image of the target swimming pool and identifying the activity postures of each person based on the surveillance image in S31, the following steps are included:

[0098] S311: Detecting the movement speed of each person through an image ranging algorithm, and calculating an activity intensity evaluation value based on the activity posture, movement speed, and a preset activity intensity evaluation formula of each person.

[0099] In this embodiment, the image ranging algorithm refers to an algorithm for detecting the distance between two points in an image and capable of detecting the speed of an object based on the time axis of the image; the activity intensity evaluation formula is:

[0100]

[0101] Among them, Y0 is the activity intensity assessment value, j is the person identifier, x is the number of people in the target swimming pool building, k Tj is the posture coefficient of person j. The value of the posture coefficient is associated with the activity posture of the corresponding person. Preferably, the posture coefficient of swimming is greater than the posture coefficients of standing and squatting, for example, 2. The posture coefficients of standing and squatting can be set to the same, for example, 1. The specific value can be set and adjusted according to actual needs; each activity area pollution threshold corresponds to an activity intensity assessment value interval, and the activity area pollution threshold is negatively correlated with the corresponding activity intensity assessment value.

[0102] Specifically, since the greater the intensity of human exercise, the more air is required to be inhaled, and the greater the impact of air pollutants, the activity speed of each person is detected through an image ranging algorithm, and combined with the corresponding activity posture of each person, the activity intensity assessment value is calculated using the activity intensity assessment formula to obtain the overall activity intensity of all people in the target swimming pool building.

[0103] S312: Match and update the corresponding activity area pollution threshold based on the activity intensity evaluation value.

[0104] Specifically, the corresponding activity area pollution threshold is matched and updated based on the activity intensity evaluation value, so that the activity area pollution threshold is set according to the overall activity intensity of all people in the target swimming pool, thereby improving the rationality of setting the air quality requirements for the main activity areas of people.

[0105] S40: When the overall pollution parameter is greater than the preset overall pollution threshold, a pollution removal instruction is generated and sent to the pollution removal component; when the activity area pollution parameter is greater than the preset activity area pollution threshold, an air flow promotion instruction is generated and sent to the air flow promotion component.

[0106] Specifically, when the overall pollution parameter is greater than the overall pollution threshold, a pollution removal instruction is generated and sent to the pollution removal component to control the pollution removal component to perform PM2.5 pollution removal work. When the activity area pollution parameter is greater than the activity area pollution threshold, an air flow promotion instruction is generated and sent to the air flow promotion component to control the air flow promotion component to drive the air flow in the main activity area of ​​​​personnel, and disperse the high-density PM2.5 in the area, thereby improving the purification efficiency of PM2.5 in the air of the indoor constant temperature swimming pool.

[0107] After step S30, the PM2.5 purification method for a double-effect heat pump heated swimming pool further includes:

[0108] S50: calculating the activity area humidity parameter based on the air humidity of each fluid grid, matching the corresponding humidity level, and a preset activity area humidity evaluation formula.

[0109] In the embodiment, the air parameters further include air humidity.

[0110] Specifically, since higher air humidity is easy to increase the breathing difficulty of the sports personnel, thereby affecting the sports performance of the swimmer, the air humidity of the main activity area of the personnel is obtained by calculating the activity area humidity parameter based on the air humidity of each fluid grid, matching the corresponding humidity level, and the activity area humidity evaluation formula;

[0111] S60: generating a decontamination instruction and sending it to the decontamination assembly when the activity area humidity parameter is greater than a preset activity area humidity threshold or the overall pollution parameter is greater than a preset overall pollution threshold.

[0112] In the embodiment, the decontamination assembly includes a fan for driving air flow, a double-effect heat pump dryer for drying air, and an air purifier for purifying PM2.5.
