Description

Technical Field

[0001] The present invention relates to the field of data processing technology, and in particular to a method, device and equipment for adaptively adjusting light intensity and linking air purification. Background Art

[0002] A photocatalytic air purifier uses photocatalytic technology to purify the air. When light strikes the surface of a photocatalyst, it absorbs the energy, creating electron-hole pairs that participate in a series of catalytic reactions. Holes have strong oxidizing properties, oxidizing airborne pollutants such as organic matter, bacteria, and viruses. Electrons, on the other hand, reduce oxygen molecules, producing reactive oxygen species such as hydroxyl radicals (·OH), which further decompose organic pollutants.

[0003] Photocatalytic air purifiers typically have a built-in light source that excites the photocatalyst to produce a photocatalytic reaction. While this internal light source excites the photocatalyst, it also results in significant energy consumption. Therefore, a photocatalytic air purification solution that reduces energy consumption while maintaining the desired photocatalytic effect is urgently needed. Summary of the Invention

[0039] The present invention will be further described in detail below with reference to specific examples, but the embodiments of the present invention are not limited thereto.

[0040] In order to facilitate understanding of the technical solution of the present invention, the following is a brief introduction to the terms involved in the present invention.

[0041] 1. Formaldehyde (HCHO): It is a volatile organic compound and a common indoor air pollutant, mainly derived from furniture and decoration materials. If the indoor formaldehyde exceeds the standard seriously, it will have a serious impact on human health.

[0042] 2. Microbial pollutants: such as bacteria, viruses and molds, etc. Mainly come from decoration building materials, human activities, air conditioning systems, heating systems, etc.

[0043] 3. Nitrogen oxides (NOx): The generation of indoor nitrogen oxides is closely related to human activities, especially from heating, cooking, smoking and other behaviors.

[0044] 4. Particulate matter (PM): refers to solid or liquid particulate matter suspended in the air. It is a pollutant that is widely present in the atmosphere. Its sources are complex and it has serious impacts on human health.

[0045] 5. Total Volatile Organic Compounds (TVOC): This represents the sum of all VOCs in indoor air. These compounds may include alkanes, aromatics, alkenes, halogenated hydrocarbons, esters, aldehydes, and other components. TVOC is a comprehensive indicator used to assess the overall level of VOC pollution in indoor air quality.

[0046] 6. Light Intensity: Also known as illuminance, it refers to the amount of visible light received per unit area. It indicates the intensity of light and the degree to which an object's surface area is illuminated. The units of light intensity are lux (abbreviated as lx) and micromoles per square meter per second (umol / m² / s). Lux is the base unit of light measurement in the International System of Units (SI) and is widely used in lighting engineering, interior design, and light environment assessment.

[0047] 7. Luminous Intensity: In photometry, luminous intensity, also referred to as light intensity or luminosity, is a physical quantity used to express the luminous flux of a light source per unit solid angle in a given direction. Luminous intensity describes the intensity and directionality of a light source. It represents the luminous flux (lumens, Lm) emitted by a light source per unit solid angle (steradian, sr) in a specific direction. The international unit of luminous intensity is the candela (cd).

[0048] An embodiment of the present invention provides a method for adaptively adjusting light intensity and linking it with air purification. The method can be performed by an electronic device, which can be a server or a terminal device. The server can be a standalone physical server, a server cluster or distributed system consisting of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be, but is not limited to, a smartphone, a tablet computer, a desktop computer, a wearable device, or the like. Of course, the electronic device can also be an indoor light source control device or a photocatalytic air purifier.

[0049] Figure 1 This is a flow chart of a method for adaptively adjusting light intensity and linking air purification provided in this embodiment. Figure 1 As shown, the main process of the method is described as follows (steps S101 to S103):

[0050] Step S101, obtaining current values of multiple indoor air quality indicators;

[0051] Step S102: If it is determined based on the current values of the multiple indoor air quality indicators that the current indoor air quality does not meet the indoor air quality standard, then determining a target total light intensity of light emitted by a catalytic light source irradiated onto a photocatalyst surface of the photocatalytic air purifier based on the current values of the multiple indoor air quality indicators and the corresponding standard values; wherein the catalytic light source includes an indoor light source and a built-in light source of the photocatalytic air purifier;

[0052] Step S103 , adjusting the luminous intensity of the indoor light source and / or the built-in light source based on the target total light intensity, so as to minimize the total energy consumption of the photocatalytic air purifier and the indoor light source when the current indoor air quality meets the indoor air quality standard.

[0053] In this embodiment, indoor air quality indicators may include, but are not limited to, formaldehyde concentration, particulate matter concentration, microbial contaminant concentration, nitrogen oxide concentration, and total volatile organic compound concentration. These concentrations can be collected in real time using corresponding sensors. For example, a formaldehyde sensor can be used to collect formaldehyde concentration; a quartz resonator can be used as a measurement sensor to collect particulate matter concentration using a piezoelectric crystal method; a biosensor can be used to collect microbial contaminant concentration; an electrochemical sensor can be used to collect nitrogen oxide concentration; and an optical sensor can be used to measure TVOC concentration in the air using the absorption, scattering, or reflection properties of light.

[0054] Since the catalytic light source used in this embodiment is an indoor light source and a built-in light source of a photocatalytic air purifier, if the indoor light source is to become a catalytic light source, the wavelength of the light source must be within the wavelength range suitable for the photocatalyst in order to effectively excite the photocatalyst and ensure the reaction rate.

[0055] In step S102, whether the current indoor air quality meets the indoor air quality standard can be determined based on the difference between the current value of each detected indoor air quality indicator and the set standard value. As long as any one indoor air quality indicator does not meet the standard, the current indoor air quality is determined to be not meeting the indoor air quality standard. Specifically, if the current value of any indoor air quality indicator is higher than the corresponding standard value, the current indoor air quality is determined to be not meeting the indoor air quality standard; if the current values of all indoor air quality indicators are not higher than the corresponding standard values, the current indoor air quality is determined to be meeting the indoor air quality standard.

[0056] It should be noted that the standard values for each indoor air quality indicator are different, and the difference between the current value and the standard value of each indoor air quality indicator is determined independently. Furthermore, when determining the target total light intensity, only indoor air quality indicators that do not meet the indoor air quality standards are considered.

[0057] In some optional embodiments, for an indoor air quality index whose current value is higher than the corresponding standard value, a target decrease rate of the indoor air quality index whose current value is higher than the corresponding standard value is determined based on the current value, standard value and preset duration of the indoor air quality index; and then the target total light intensity is determined based on the target decrease rate of all indoor air quality indicators whose current values are higher than the corresponding standard values.

[0058] The target descent rate is obtained by first calculating the difference between the current value and the standard value, and then calculating the ratio of the difference to the preset time length.

[0059] After the target drop rate is determined, there are two situations to determine the target total light intensity:

[0060] (1) Only one current value of the indoor air quality index is higher than the corresponding standard value;

[0061] Light intensity is a key factor influencing the effectiveness of photocatalysts. Sufficient light intensity ensures that the photocatalyst fully absorbs light energy and initiates the chemical reaction. In photocatalytic reactions, increasing light intensity generally leads to an increase in reaction rate. While increasing light intensity can promote photocatalytic reactions, the relationship between degradation efficiency and increased light intensity is not linear. When light intensity reaches a certain level, the increase in reaction rate generally tends to level off because the active sites of the photocatalyst may be saturated.

[0062] Therefore, when the light intensity reaches a certain value, the indoor air quality index's rate of decline will no longer change significantly, tending to be flat and approximately constant. This approximately constant rate of decline is defined as the preset rate of decline. If the calculated target rate of decline is greater than the preset rate of decline, it means that there is no suitable light intensity to achieve the target rate of decline, and a staged decline is required.

[0063] Specifically, first select at least one intermediate value between the current value and the standard value, and arrange the current value, the standard value and at least one intermediate value in descending order to form a first array; then calculate the first sub-decline rates of two adjacent values in the first array in sequence based on the preset time length; wherein all first sub-decline rates are not greater than the preset decline rate; then query the target total light intensity corresponding to each first sub-decline rate on the preset mapping curve in sequence, and arrange the queried target total light intensities in accordance with the query order to form a second array.

[0064] The first sub-rate is the ratio of the difference between two adjacent values in the first array to a preset duration. The second array includes at least two target total light intensities, and the luminous intensity of the catalytic light source is subsequently adjusted according to the target light intensities in the second array.

[0065] In this embodiment, the preset mapping curve is a curve showing the decrease rate of the indoor air quality index as a function of light intensity. As light intensity increases, the decrease rate increases accordingly, but when the light intensity increases to a certain value, the decrease rate remains almost unchanged.

[0066] It should be noted that the calculation of the target reduction rate and the first sub-reduction rate both adopts the same preset time length, which is consistent with the preset time length adopted for calculating the reduction rate of the indoor air quality index in the preset mapping curve.

[0067] (2) The current values of multiple indoor air quality indicators are higher than the corresponding standard values;

[0068] First, the current total light intensity of the light emitted by the catalytic light source irradiating the photocatalyst surface is increased by the preset light intensity to form a new current total light intensity, and the second sub-decline rate corresponding to each indoor air quality standard under the new total light intensity is queried respectively;

[0069] If the second sub-decline rate of at least one indoor air quality standard is less than the corresponding target decline rate, then continuing to perform the steps of increasing the current total light intensity of the light emitted by the catalytic light source to the surface of the photocatalyst by a preset light intensity to form a new current total light intensity, and respectively querying the second sub-decline rate corresponding to each indoor air quality standard under the new total light intensity;

[0070] If the second sub-reduction rates of all indoor air quality standards are not less than the corresponding target reduction rates, the new total light intensity is determined as the target total light intensity.

[0071] The second sub-decline rate is also obtained by querying the preset mapping curve. Each indoor air quality index corresponds to a mapping curve of the decline rate of the indoor air quality index and the total light intensity.

[0072] Since the decline rates of various indoor air quality indicators under the same light intensity are not the same, the optimal light intensity required to achieve compliance with indoor air quality standards for various indoor air quality indicators is different. Therefore, it is necessary to set a preset light intensity to help find the minimum light intensity corresponding to the compliance of various indoor air quality indicators.

[0073] In some optional embodiments, after determining the target total light intensity, the luminous intensity of the indoor light source and the photocatalytic air purifier needs to be adjusted in combination with the lowest total energy consumption of the indoor light source and the photocatalytic air purifier. The target total light intensity and total energy consumption need to satisfy the following equations:

[0074] ;

[0075] Where, is the target total light intensity; is the first target luminous intensity of the indoor light source; is the second target luminous intensity of the built-in light source; is the first light loss coefficient of the indoor light source; is the second light loss coefficient of the built-in light source; is the total energy consumption value; The first target luminous intensity of the indoor light source the corresponding first energy consumption value; The second target luminous intensity of the built-in light source The corresponding second energy consumption value.

[0076] Among them, the first light loss coefficient , the second light loss coefficient It is related to factors such as the light propagation medium, propagation distance, and propagation direction, and can be obtained through experiments.

[0077] It should be noted that the first energy consumption value , the second energy consumption value Both can pass the first target luminous intensity , the second target luminous intensity Specifically, first calculate the luminous flux based on the luminous intensity, then calculate the light source power based on the luminous efficiency provided by the light source manufacturer, and finally determine the energy consumption value based on the light source power and time.

[0078] In this embodiment, The lowest target is to find the appropriate first target luminous intensity and the second target luminous intensity It may be possible to adjust only one of the catalytic light sources, that is, to adjust only the luminous intensity of the indoor light source and keep the luminous intensity of the built-in light source unchanged, or to adjust only the luminous intensity of the built-in light source and keep the luminous intensity of the indoor light source unchanged.

[0079] Based on the same inventive concept, an embodiment of the present invention provides a device for adaptively adjusting light intensity and linking air purification. Figure 2 This is a structural block diagram of a light intensity adaptive adjustment and air purification linkage device 200 provided by an embodiment of the present invention. Figure 2 As shown, the light intensity adaptive adjustment and air purification linkage device 200 mainly includes:

[0080] The current value acquisition module 201 is used to obtain the current values of multiple indoor air quality indicators;

[0082] The light intensity adjustment module 203 is used to adjust the luminous intensity of the indoor light source and / or the built-in light source based on the target total light intensity so as to minimize the total energy consumption of the photocatalytic air purifier and the indoor light source when the current indoor air quality meets the indoor air quality standard.

[0083] In some optional embodiments, the light intensity determination module 202 is specifically used to determine that the current indoor air quality does not meet the indoor air quality standard if the current value of any indoor air quality indicator is higher than the corresponding standard value; if the current values of all indoor air quality indicators are not higher than the corresponding standard values, then determine that the current indoor air quality meets the indoor air quality standard.

[0084] In some optional embodiments, the light intensity determination module 202 includes:

[0085] a first determining module configured to determine, for an indoor air quality index whose current value is higher than a corresponding standard value, a target decrease rate of the indoor air quality index whose current value is higher than the corresponding standard value based on the current value, the standard value, and a preset time period of the indoor air quality index;

[0086] The second determining module is configured to determine a target total light intensity based on a target decrease rate of all indoor air quality indicators whose current values are higher than corresponding standard values.

[0087] Optionally, a second determination module is specifically used to, when only one current value of the indoor air quality indicator is higher than the corresponding standard value, if the target decrease rate is greater than the preset decrease rate, select at least one intermediate value between the current value and the standard value, and arrange the current value, the standard value and at least one intermediate value in descending order to form a first array; calculate the first sub-decline rates of two adjacent values in the first array in sequence based on a preset time length; wherein all first sub-decline rates are not greater than the preset decrease rate; query the target total light intensity corresponding to each first sub-decline rate on the preset mapping curve in sequence, and arrange the queried target total light intensities in accordance with the query order to form a second array.

[0088] Furthermore, the target descent rate is obtained by first calculating the difference between the current value and the standard value, and then calculating the ratio of the difference to the preset time length.

[0089] Optionally, the second determination module is specifically used to increase the current total light intensity of the light emitted by the catalytic light source to the photocatalyst surface by the preset light intensity when the current values of multiple indoor air quality indicators are higher than the corresponding standard values, to form a new current total light intensity, and to query the second sub-decline rate corresponding to each indoor air quality standard under the new total light intensity respectively; if the second sub-decline rate of at least one indoor air quality standard is less than the corresponding target decline rate, then continue to execute the steps of increasing the current total light intensity of the light emitted by the catalytic light source to the photocatalyst surface by the preset light intensity to form a new current total light intensity, and to query the second sub-decline rate corresponding to each indoor air quality standard under the new total light intensity respectively; if the second sub-decline rates of all indoor air quality standards are not less than the corresponding target decline rates, then the new total light intensity is determined as the target total light intensity.

[0090] In some optional embodiments, the target total illumination intensity and total energy consumption values satisfy the following equations:

[0091] ;

[0092] Where, is the target total light intensity; is the first target luminous intensity of the indoor light source; is the second target luminous intensity of the built-in light source; is the first light loss coefficient of the indoor light source; is the second light loss coefficient of the built-in light source; is the total energy consumption value; The first target luminous intensity of the indoor light source the corresponding first energy consumption value; Second target luminous intensity for the built-in light source The corresponding second energy consumption value.
