Referring to fig. 2, a method for controlling a carbon dioxide adsorption module includes:
s201, obtaining the current carbon dioxide concentration in the room.
The carbon dioxide concentration here may be a carbon dioxide concentration directly detected by a carbon dioxide sensor, for example, when the carbon dioxide adsorption module is provided on an air conditioner, the carbon dioxide concentration in the room may be directly detected by the carbon dioxide sensor provided on the air conditioner, or the carbon dioxide concentration in the room may be directly detected by a separate carbon dioxide sensor provided at another location in the room.
Or the current carbon dioxide concentration is obtained by compensating the current detection concentration directly detected by the carbon dioxide sensor.
For example, prior to obtaining the current carbon dioxide concentration within the chamber, the method for controlling the carbon dioxide adsorption module further comprises: acquiring the number of indoor personnel and the activity state of the personnel; a current carbon dioxide production rate corresponding to the number of people and the activity status of the people is determined. Obtaining a current carbon dioxide concentration within the chamber based on obtaining the current carbon dioxide generation rate may include: obtaining the current detection concentration through a carbon dioxide sensor; and compensating the current detection concentration according to the current carbon dioxide generation rate to obtain the current carbon dioxide concentration.
Indoor image information can be obtained through the camera equipment, the number of personnel in the image information is obtained through an image analysis technology, the current carbon dioxide generation rate is positively correlated with the number of personnel, and the larger the number of personnel is, the larger the current carbon dioxide generation rate is; the personnel moving distance can be obtained by analyzing the position change of personnel in a plurality of continuously shot images, the personnel moving speed is determined according to the shooting interval duration and the personnel moving distance of the images, namely the personnel activity state (including the personnel moving speed) is obtained, the current carbon dioxide generation rate is positively correlated with the personnel moving speed, and the larger the personnel moving speed is, the larger the current carbon dioxide generation rate is.
The number of people and the activity state of the people can be obtained through the wearable devices, for example, the number of the wearable devices in a room is obtained, and the number of the wearable devices is determined as the number of the people; obtain personnel's rhythm of the heart through wearable equipment, personnel's rhythm of the heart is higher, and it is more violent to represent personnel's activity state, and the activity state is more violent, and then carbon dioxide production rate is big more, that is, personnel's rate and carbon dioxide production rate are positive correlation.
In some practical applications, the corresponding relationship between the number of people, the state of people, and the carbon dioxide generation rate may be pre-stored in a database, and after the number of people and the state of people are obtained, the current carbon dioxide generation rate corresponding to the number of people and the state of people may be obtained.
In the process of compensating the current detection concentration according to the current carbon dioxide generation rate and obtaining the current carbon dioxide concentration, the higher the current carbon dioxide generation rate is, the greater the compensation effect of the current carbon dioxide generation rate on the current detection concentration is, so that the greater the first difference between the current carbon dioxide concentration and the current detection concentration is.
The corresponding relation between the current carbon dioxide generation rate and the compensation value can be stored in advance, after the current carbon dioxide generation rate and the current detection concentration are obtained, the compensation value corresponding to the current carbon dioxide generation is obtained in the database, the sum of the compensation value and the current detection concentration is obtained, and the sum of the compensation value and the current detection concentration is determined as the current carbon dioxide concentration.
The higher the carbon dioxide concentration is, the larger the adsorption rate of the carbon dioxide adsorption module is, and in the technical scheme, the current carbon dioxide concentration is higher than the current detection concentration, so that the adsorption rate of the carbon dioxide adsorption module can be increased in advance to offset the influence of the current carbon dioxide generation rate on the indoor actual carbon dioxide concentration, and the indoor carbon dioxide concentration can be better maintained in a reasonable range.
Optionally, compensating the current detected concentration according to the current carbon dioxide generation rate to obtain the current carbon dioxide concentration, including: obtaining the integral of the current carbon dioxide generation rate to the preset duration; determining a predicted change concentration from the integral; and determining the sum of the current detection concentration and the predicted change concentration as the current carbon dioxide concentration.
The preset time duration represents the time duration required by the influence of the current carbon dioxide generation rate on the indoor environment, the preset time duration is in positive correlation with the indoor volume, and the longer the indoor volume is, the longer the preset time duration is; the smaller the indoor volume, the shorter the preset time period.
The technical scheme can realize the accurate compensation of the current detection concentration.
S202, determining the set air volume of the fan and the set adsorption area of the carbon dioxide adsorption module according to the current carbon dioxide concentration.
Wherein the air volume of the fan and/or the adsorption area is set to be positively correlated with the current carbon dioxide concentration.
After the current carbon dioxide concentration is increased, the set air quantity of the fan can be maintained unchanged, and the adsorption area is increased; or the air quantity of the set fan can be increased, and the adsorption area is kept unchanged; or, the set fan air volume and the adsorption area are simultaneously improved.
After the current carbon dioxide concentration is reduced, the air quantity of the fan can be set to be constant, and the adsorption area is reduced; or, the air quantity of the set fan can be reduced, and the adsorption area is kept unchanged; or, the set fan air volume and the adsorption area are reduced simultaneously.
Optionally, determining the air volume of the set fan and the adsorption area according to the current carbon dioxide concentration includes: determining the current concentration range of the current carbon dioxide concentration within a preset concentration range; determining the current adsorption rate corresponding to the current concentration range according to the corresponding relation between the concentration range and the adsorption rate; and determining the set air volume of the fan and the set adsorption area according to the current adsorption rate.
The predetermined concentration range includes a plurality of concentration ranges, for example, a first concentration range in the predetermined concentration range may be greater than 400ppm and less than 1000ppm, a second concentration range in the predetermined concentration range may be greater than or equal to 1000ppm and less than or equal to 2000ppm, and a third concentration range in the predetermined concentration range may be greater than 2000 ppm. The greater the number of concentration ranges, the more precise the control of the carbon dioxide adsorption module, the smaller the span of one concentration range (for example, the span of the second concentration range is 2000ppm-1000 ppm), and the more precise the control of the carbon dioxide adsorption module.
The adsorption rate may be represented by a specific value, or may be represented by a gear, such as a first gear, a second gear, and a third gear, where the specific value of the adsorption rate for the first gear is smaller than the specific value of the adsorption rate for the second gear, and the specific value of the adsorption rate for the second gear is smaller than the specific value of the adsorption rate for the third gear. In practical applications, the specific values of the adsorption rates corresponding to the first gear, the second gear and the third gear may be determined according to the specific value of the maximum adsorption rate of the carbon dioxide adsorption module, for example, 95% of the specific value of the maximum adsorption rate of the carbon dioxide adsorption module is used as the specific value of the adsorption rate corresponding to the third gear, 2/3 of the specific value of the adsorption rate corresponding to the third gear is used as the specific value of the adsorption rate corresponding to the second gear, and 1/3 of the specific value of the adsorption rate corresponding to the third gear is used as the specific value of the adsorption rate corresponding to the first gear. The more the number of the gears is, the more accurate the control of the carbon dioxide adsorption module is, the smaller the difference value between adsorption rates corresponding to adjacent gears is, and the more accurate the control of the carbon dioxide adsorption module is, and the three gears are only exemplary illustrations without limiting the embodiment of the present disclosure.
Optionally, determining the set air volume of the fan and the set adsorption area according to the current adsorption rate includes: and determining the set fan air volume and the set adsorption area corresponding to the current adsorption rate according to the corresponding relation among the adsorption rate, the fan air volume and the adsorption area.
The corresponding relationship between the concentration range and the adsorption rate can be stored in a database in advance, and after the current carbon dioxide concentration is determined and the current concentration range is determined in the preset concentration range, the adsorption rate corresponding to the current concentration range can be inquired in the database.
By adopting the technical scheme, the set air quantity of the fan and the set adsorption area can be determined, and then the carbon dioxide adsorption module is accurately controlled.
In practical application, along with the adsorption of the carbon dioxide of the adsorption material of the carbon dioxide adsorption module, the adsorption performance of the adsorption material of the carbon dioxide adsorption module is reduced, and the concrete embodiment is as follows: controlling the carbon dioxide adsorption module to operate according to the air volume of the specific fan and the specific adsorption area immediately after the adsorption material in the carbon dioxide adsorption module is updated, and recording the adsorption rate of the carbon dioxide adsorption module as a first rate; after the carbon dioxide adsorption module is used for a plurality of days, the carbon dioxide adsorption module is still controlled to operate according to the specific air volume of the fan and the specific adsorption area, the adsorption rate of the carbon dioxide adsorption module is recorded as the second rate, and the first rate is greater than the second rate.
In this case, the method for controlling the carbon dioxide adsorption module may further include: within a set time period, obtaining a first average carbon dioxide concentration at an inlet of a carbon dioxide adsorption module and a second average carbon dioxide concentration at an outlet of the carbon dioxide adsorption module; obtaining a concentration difference value between the first average concentration of the carbon dioxide and the second average concentration of the carbon dioxide; on this basis, confirm according to setting for carbon dioxide concentration and set for the fan amount of wind and set for the adsorption area, can include: and determining the set air volume of the fan and the set adsorption area according to the set carbon dioxide concentration and the concentration difference value, so that the ratio of the set adsorption area to the set air volume of the fan is inversely related to the concentration difference value.
The set duration may be a set duration in each test period, for example, a set duration after the start time of each test period; here, the test period refers to a period for detecting the adsorption performance of the adsorption material in the carbon dioxide adsorption module, and for example, the test period may be one day, two days, or more.
The set time period may also be a set time period before the present time, which refers to the time at which the control for the carbon dioxide adsorption module is performed.
The set time period may be 10min, 20min, 30min, 1h or longer.
The concentration difference value can reflect the performance of the adsorbing material of the carbon dioxide adsorbing module for adsorbing carbon dioxide, and the larger the concentration difference value is, the better the performance of the adsorbing material for adsorbing carbon dioxide is; the smaller the concentration difference, the poorer the performance of the adsorbing material for adsorbing carbon dioxide.
In the working process of the carbon dioxide adsorption module, under the condition that the air volume of the fan is not changed, the larger the adsorption area is, the more the air in unit volume passes through the adsorption material by the adsorption area, the more the carbon dioxide concentration in the unit volume is reduced, namely, the higher the carbon dioxide adsorption module is in adsorbing carbon dioxide; under the unchangeable condition of adsorption area, the fan amount of wind is big more, and the air of unit volume passes through adsorption material with this fan amount of wind, and the carbon dioxide concentration reduces less in this unit volume, namely, the carbon dioxide adsorption module adsorbs the performance of carbon dioxide and is lower.
Adopt aforementioned technical scheme, if the concentration difference diminishes, the performance that the adsorption material of the carbon dioxide adsorption module that shows adsorbs the carbon dioxide reduces, and under the unchangeable condition of the ratio of setting for adsorption area and setting for the fan amount of wind, the performance that the carbon dioxide adsorption module shows adsorbs the carbon dioxide will reduce, improves this moment and sets for the ratio of adsorption area and setting for the fan amount of wind, is favorable to improving the adsorption performance that the whole absorption carbon dioxide that shows of carbon dioxide adsorption module. Thus, the performance of adsorbing carbon dioxide exhibited by the carbon dioxide adsorbing module can be maintained in a preferable state.
The inverse correlation relation between the ratio of the set adsorption area to the set fan air volume and the concentration difference can be stored in a database, and after the concentration difference is obtained, the inverse correlation relation between the ratio and the concentration difference can be obtained by inquiring the database.
Optionally, determining the air volume of the set fan and the adsorption area according to the current carbon dioxide concentration and the concentration difference value includes: obtaining a ratio inversely related to the concentration difference; determining the air volume of a set fan according to the current carbon dioxide concentration; and determining the set adsorption area according to the set air volume and the ratio of the fan. The adsorption rate of the carbon dioxide adsorption module is positively correlated with the current carbon dioxide concentration, and the product of the air quantity of the fan and the adsorption area is set; after obtaining the ratio inversely correlated with the concentration difference, according to this ratio, will set for the adsorption area and replace for setting for the fan amount of wind, then set for the product of the square of fan amount of wind and ratio, with current carbon dioxide concentration positive correlation, like this, can confirm according to current carbon dioxide concentration and set for the fan amount of wind, according to the ratio again, will set for the fan amount of wind and convert to and set for the adsorption area (set for the adsorption area and be the product of fan amount of wind and ratio). Thus, the set fan air volume and the set adsorption area can be obtained.
Or, according to the current carbon dioxide concentration and the concentration difference, determining the set air volume of the fan and the set adsorption area, which may include: determining a set adsorption area according to the current carbon dioxide concentration; obtaining a ratio inversely related to the concentration difference; and determining the set air volume of the fan according to the set adsorption area and the ratio. The adsorption rate of the carbon dioxide adsorption module is positively correlated with the current carbon dioxide concentration, and the product of the air quantity of the fan and the set adsorption area is set; after obtaining the ratio inversely correlated with the concentration difference, according to the ratio, the set fan air volume is replaced by the set adsorption area, then the product of the square of the set adsorption area and the ratio is set, and is positively correlated with the current carbon dioxide concentration, so that the set adsorption area can be determined according to the current carbon dioxide concentration, and then the set adsorption area is converted into the set fan air volume (the set fan air volume is the quotient of dividing the set adsorption area by the ratio). Thus, the set fan air volume and the set adsorption area can be obtained.
And S203, adjusting the carbon dioxide adsorption module according to the set air volume of the fan and the set adsorption area.
Conventional adjustment means can be used here, for example: obtaining the actual air volume of the fan, and improving the actual air volume of the fan under the condition that the set air volume of the fan is larger than the set air volume of the fan, so that the actual air volume of the fan reaches the set air volume of the fan; and under the condition that the set fan air volume is smaller than the actual fan air volume, reducing the actual fan air volume to enable the actual fan air volume to reach the set fan air volume.
Under the condition that the set adsorption area is larger than the actual adsorption area, the actual adsorption area is increased to reach the set adsorption area; and under the condition that the set adsorption area is smaller than the actual adsorption area, reducing the actual adsorption area to enable the actual adsorption area to reach the set adsorption area.
The set air volume of the fan and the set adsorption area of the carbon dioxide adsorption module are determined according to the current carbon dioxide concentration, when the indoor carbon dioxide concentration is higher, the set air volume of the fan and/or the set adsorption area are/is larger, at the moment, the power consumption of the carbon dioxide adsorption module is higher, but the adsorption performance of the carbon dioxide is higher, and the indoor carbon dioxide concentration can be reduced quickly; when the indoor carbon dioxide concentration is lower, the set fan air volume and/or the set adsorption area are smaller, the power consumption of the carbon dioxide adsorption module is lower at the moment, but the adsorption performance of the carbon dioxide is lower, and the indoor carbon dioxide concentration is favorably maintained at a certain concentration. By adopting the technical scheme, the balance of the performance of adsorbing carbon dioxide and the power consumption can be realized. In addition, noise may also be reduced when the carbon dioxide adsorption module is operating at low power.
