The invention provides an air conditioner sterilization control method. The air conditioner is provided with a sterilization module, and the method can be implemented in a main control module of the air conditioner, such as a main MCU of the air conditioner.
For example, fig. 2 is a block diagram of an air conditioner sterilization system according to an embodiment of the present invention. As shown in fig. 2, the detection and identification module is used for detecting and identifying whether the user (human) is the user, and identifying the type (old people, children, pregnant women) to which the user belongs, such as a millimeter wave radar sensor, an infrared sensor or a camera; the main control module is, for example, a main MCU for controlling the operation of each function of the air conditioner; an air quality detection module, such as a PM2.5 sensor, for detecting the PM2.5 content in the air; the sterilization module, for example, comprises a UVC sterilization module. The UVC sterilization module can adopt a constant current chip to drive an LED lamp bead to emit light, and the LED current can be set to be large or small through an external current detection resistor; different currents can be obtained by different resistance values, and different ultraviolet light with different brightness can be emitted by different currents flowing through the LED, so that different sterilization intensities, namely different degrees of sterilization capability can be obtained.
Fig. 1 is a method schematic diagram of an embodiment of a sterilization control method of an air conditioner according to the present invention.
As shown in fig. 1, according to an embodiment of the present invention, the sterilization control method of an air conditioner includes at least step S110, step S120, and step S130.
And step S110, detecting whether a user exists in the room or not under the condition that the sterilization module is started.
For example, in the case where the sterilization module is turned on, whether there is a user in the room is detected by detecting an identification module, such as a millimeter wave radar sensor, an infrared sensor, or a camera. For example, the short wavelength electromagnetic wave emitted by the millimeter wave radar sensor can detect the movement as small as a few tenths of millimeters, and can accurately identify the slight movements of the thorax such as the fluctuation and the blinking of eyes when a living body breathes, so that the living body and the non-living body are distinguished, and meanwhile, the human body and the non-human body are judged through the limb movement of the living body. Whether a human body exists indoors can be judged according to infrared thermal imaging through the infrared sensor. The camera is used for collecting indoor images and identifying the images, so that whether a human body exists indoors can be identified.
Step S120, if it is detected that there is a user in the room, determining the type of the indoor user.
In one embodiment, the user is classified into an elderly person, a child, a pregnant woman, a young adult, or an adult. For example, when a person is detected in a room, the type of the indoor user can be judged by performing heart rate pulse monitoring, limb movement detection, person shape detection and the like through the millimeter wave radar, and the type of the indoor user is judged by comparing and analyzing the monitored data with reference data stored in advance. For another example, when a person is detected in a room, the camera captures an image, and performs image recognition to determine the type of the indoor user.
And step S130, controlling the sterilization intensity of the sterilization module according to the type of the indoor user.
Specifically, the sterilization intensity of the sterilization module is controlled according to the indoor air quality of the indoor room and the type of the indoor user. The indoor air quality may detect the PM2.5 concentration by a PM2.5 sensor, for example. According to the national standard, the air quality standard of "excellent" is below 35 micrograms/cubic meter of 24-hour pm2.5 average concentration, the air quality standard of "good" is below 75 micrograms/cubic meter, the pollution level is reached above 75 micrograms/cubic meter, certain harm is caused to human bodies, and the pollution level is severe above 300 micrograms/cubic meter. However, in the present situation, even in spring and summer, which have good air quality, more than 75 of the air quality is still in a normal state, and in autumn and winter, which have heavy haze, the air quality is in a state of more than 300 of the air quality, and people stay indoors for 80% of the time, and indoor purification is imperative. Since PM2.5 is a good carrier for viruses and bacteria, when the air quality index PM2.5 is changed, it means that viruses and bacteria in the air are increased or decreased, so that the sterilization intensity can be adjusted according to the concentration of PM 2.5.
Different sterilization intensities are adopted for different air quality grades, and under the conditions that the higher the air quality grade is, the better the air quality is, the lower the air quality grade is, and the worse the air quality is, the higher the grade of the indoor air quality in the first preset air quality grade classification or the second preset air quality grade classification is, the lower the sterilization intensity of the sterilization module is, and vice versa. In one embodiment, when the indoor user is a preset type of user, the sterilization intensity of the sterilization module is controlled according to a class to which the indoor air quality belongs in a first preset air quality class classification. When the indoor user is not a preset type of user, the sterilization intensity of the sterilization module is controlled according to the level to which the indoor air quality belongs in the second preset air quality level classification.
In one embodiment, the predetermined types of users include the elderly, children, pregnant women. The first preset air quality class classification comprises more than two air quality classes; the second predetermined air quality class classification includes more than two air quality classes. Optionally, the first and second predetermined air quality class classifications include the same number of air quality classes, for example, the same air quality class classification, and the same class in the first and second predetermined air quality class classifications corresponds to different air quality parameter value ranges.
In an alternative embodiment, the first preset air quality class classification from high to low includes three classes of good, good and poor, and the second preset air quality class classification from high to low also includes three classes of good, good and poor; the numerical range of the air quality parameter corresponding to each of the first three grades of the high, good and poor air quality grades is different from the numerical range of the air quality parameter corresponding to each of the second three grades of the high, good and poor air quality grades. For example, in the first air quality class, an air quality value M.ltoreq.35 (air quality value is, for example, PM2.5 concentration in units of. mu.g/cubic meter), which represents that the air quality class is good, an air quality value 35 < M.ltoreq.75, which represents that the air quality class is good, an air quality value M > 75, which represents that the air quality class is poor; in the first air quality grade classification, the air quality value M is less than or equal to 66, which represents that the air quality grade is good, the air quality value 66 is greater than or equal to M and less than or equal to 150, which represents that the air quality grade is good, and the air quality value M is greater than 150, which represents that the air quality grade is poor.
Preferably, the corresponding first air quality class is more demanding for a preset type of user. For example, the first and second preset air quality class classifications comprise the same air quality class classification, the air quality requirement of each class in the first air quality class classification being higher than the air quality requirement of the same class in the first air quality class classification. For example, when the air quality parameter value is larger, the air quality is worse, the air quality level is lower, the air quality parameter value is smaller, the air quality is better, and the air quality level is higher (for example, the higher the PM2.5 index indicates that the higher the PM2.5 concentration in the air is, the worse the air quality is), the upper limit value and/or the lower limit value of the air quality parameter value range corresponding to each level in the first preset air quality level class is smaller than the upper limit value and/or the lower limit value of the air quality parameter value range corresponding to the same level in the second preset air quality level class.
In one embodiment, the sterilization module is a UVC (ultraviolet) sterilization module, the sterilization intensity of the UVC sterilization module can be controlled by controlling the current intensity of the sterilization part of the UVC sterilization module, and the light emission intensity (brightness) of the LED lamp, that is, the sterilization intensity of the ultraviolet sterilization can be controlled by controlling the current intensity of the LED lamp of the UVC sterilization module. For example, an adjustable resistor control circuit of the UVC sterilization module is driven by sending signals, an external current adjustable detection resistor is adjusted, the current is changed due to the change of the resistance value of the resistor, the current flowing through the LED is changed, and the brightness is changed accordingly, namely the sterilization intensity is increased when the current is increased. For example, the range of values of the air quality parameter M corresponding to the first air quality class category includes: an air mass value M of 35 or less (M is, for example, PM2.5 concentration in units of. mu.g/cubic meter), an air mass value of 35 or more and M of 75 or less and an air mass value of M of 75 or more; the air quality parameter value ranges corresponding to the second air quality class classification include: the air mass value M is less than or equal to 66, the air mass value 66 is greater than or equal to 150 and the air mass value M is greater than 150. If it is detected that an indoor person is an old person, a child or a pregnant woman (any one or more than two of the old person, the child and the pregnant woman), when the air quality value M is less than or equal to 35, the air quality level is excellent, the LED current can be small, for example, the I is 70mA, the luminous brightness is low, the sterilization capability is relatively weak, and the air quality can still be ensured; when the air quality value is more than 35 and less than or equal to 75, the air quality grade is good, the LED current is adjusted to be 110mA, and medium sterilization capacity is achieved; when M is more than 75, the air quality grade is poor, the LED operates at the maximum current I of 150mA, and the sterilizing capability reaches the highest level. If the old, children and pregnant women are detected to be absent indoors, when the air quality value M is less than or equal to 66, the air quality level is excellent, the LED current can be small, for example, the I is 70mA, the luminous brightness is low, the sterilization capability is relatively weak, and the air quality can still be ensured; when the air quality value is more than 66 and less than or equal to 150, the air quality grade is good, the LED current is adjusted to be 110mA, and medium sterilization capacity is achieved; when M is more than 150, the air quality grade is poor, the LED operates at the maximum current I of 150mA, and the sterilizing capability reaches the highest level.
According to the embodiment of the invention, different air quality grade measurement standards are adopted for different types of users, and sterilization intensity control is performed according to the air quality grade, so that the requirements of different types of users on the air quality can be met. And moreover, the sterilization intensity is controlled according to the air quality grade, so that the power consumption of the air conditioner can be reduced under the condition of ensuring the maximum sterilization capability, and the aim of saving energy is fulfilled.
Optionally, if it is detected that no user is present in the room, the sterilization module is controlled to operate at a preset sterilization intensity. Preferably, the preset sterilization intensity is lower than the sterilization intensity of the sterilization module during normal sterilization. For example, the sterilization module is a UVC sterilization module, and the current intensity of the sterilization component of the UVC sterilization module is controlled to control the light emission intensity (brightness) of the LED lamp, thereby controlling the sterilization intensity of the UVC sterilization module. For example, if it is detected that there is no user in the room, the LED lamp may be controlled to operate at a preset brightness, where the preset brightness is lower than the brightness of the LED lamp during normal sterilization. When no user is in the room, the sterilization module is controlled to operate at a lower sterilization intensity, so that the power consumption of the air conditioner can be reduced, and the aim of saving energy is fulfilled.
For clearly explaining the technical solution of the present invention, the following describes an execution flow of the air conditioner sterilization control method provided by the present invention with a specific embodiment.
Fig. 3 is a schematic method diagram of a sterilization control method for an air conditioner according to an embodiment of the present invention. As shown in fig. 3, the air conditioner sterilization module is a UVC sterilization module, after the UVC sterilization function is turned on, whether a person is present indoors is detected by a millimeter wave radar, and if no person is present indoors, the UVC sterilization module is dormant or the LED is operated at a preset brightness (i.e., a low brightness, such as a minimum brightness); if a person is detected indoors, whether the person indoors has an old person, a child or a pregnant woman is further judged through data detected by the millimeter wave radar, if the person indoors has the old person, the child or the pregnant woman, the grade of indoor air quality in the first air quality grade class is detected through the PM2.5 sensor, when the air quality value M is smaller than or equal to 35, the grade of the indoor air quality is excellent, the LED current is smaller, the I is 70mA, the luminous brightness is lower, the sterilization capability is relatively weaker, and the air quality can still be ensured; when the air quality value is more than 35 and less than or equal to 75, the air quality grade is good, the LED current is adjusted to be 110mA, and medium sterilization capacity is achieved; when M is more than 75, the air quality grade is poor, the LED operates at the maximum current I of 150mA, and the sterilizing capability reaches the highest level. If the old, the child and the pregnant woman do not exist indoors, detecting the belonged grade of the indoor air quality in a second air quality grade classification through a PM2.5 sensor, wherein the air quality parameter numerical range corresponding to the second air quality grade classification comprises the following steps: the air quality value M is less than or equal to 66, the air quality value is greater than or equal to 150 and the air quality value M is greater than 150, when the air quality value M is less than or equal to 66, the air quality level is high, the LED current can be small, for example, if I is 70mA, the luminous brightness is low, the sterilization capability is relatively weak, but the air quality can still be ensured; when the air quality value is more than 66 and less than or equal to 150, the air quality grade is good, the LED current is adjusted to be 110mA, and medium sterilization capacity is achieved; when M is more than 150, the air quality grade is poor, the LED operates at the maximum current I of 150mA, and the sterilizing capability reaches the highest level.
The invention also provides an air conditioner sterilization control device. The air conditioner has a sterilization module, and the device can be implemented in a main control module of the air conditioner, such as a main MCU of the air conditioner.
For example, fig. 2 is a block diagram of an air conditioner sterilization system according to an embodiment of the present invention. As shown in fig. 2, the detection and identification module is used for detecting and identifying whether the user (human) is the user, and identifying the type (old people, children, pregnant women) to which the user belongs, such as a millimeter wave radar sensor, an infrared sensor or a camera; the main control module is, for example, a main MCU for controlling the operation of each function of the air conditioner; an air quality detection module, such as a PM2.5 sensor, for detecting the PM2.5 content in the air; the sterilization module, for example, comprises a UVC sterilization module. The UVC sterilization module can adopt a constant current chip to drive an LED lamp bead to emit light, and the LED current can be set to be large or small through an external current detection resistor; different currents can be obtained by different resistance values, and different ultraviolet light with different brightness can be emitted by different currents flowing through the LED, so that different sterilization intensities, namely different degrees of sterilization capability can be obtained.
Fig. 4 is a schematic structural diagram of an embodiment of an air conditioner sterilization control device provided by the invention. As shown in fig. 4, the air conditioner sterilization control apparatus 100 includes a detection unit 110, a determination unit 120, and a control unit 130.
The detection unit 110 is used for detecting whether a user is in the room or not when the sterilization module is turned on.
For example, in the case where the sterilization module is turned on, whether there is a user in the room is detected by detecting an identification module, such as a millimeter wave radar sensor, an infrared sensor, or a camera. For example, the short wavelength electromagnetic wave emitted by the millimeter wave radar sensor can detect the movement as small as a few tenths of millimeters, and can accurately identify the slight movements of the thorax such as the fluctuation and the blinking of eyes when a living body breathes, so that the living body and the non-living body are distinguished, and meanwhile, the human body and the non-human body are judged through the limb movement of the living body. Whether a human body exists indoors can be judged according to infrared thermal imaging through the infrared sensor. The camera is used for collecting indoor images and identifying the images, so that whether a human body exists indoors can be identified.
The determining unit 120 is configured to determine the type of the indoor user if the detecting unit 110 detects that there is a user in the room.
In one embodiment, the user is classified into an elderly person, a child, a pregnant woman, a young adult, or an adult. For example, when a person is detected in a room, the type of the indoor user can be judged by performing heart rate pulse beat monitoring, limb movement detection, person shape detection and the like through the millimeter wave radar, and the type of the indoor user is determined by comparing and analyzing the monitored data with reference data stored in advance. For another example, when a person is detected in a room, the camera captures an image, and performs image recognition to determine the type of the indoor user.
The control unit 130 is used for controlling the sterilization intensity of the sterilization module according to the type of the indoor user.
Specifically, the control unit 130 controls the sterilization intensity of the sterilization module according to the indoor air quality in the room where the sterilization module is located and the type of the indoor user. The indoor air quality may detect the PM2.5 concentration by a PM2.5 sensor, for example. According to the national standard, the air quality standard of "excellent" is below 35 micrograms/cubic meter of 24-hour pm2.5 average concentration, the air quality standard of "good" is below 75 micrograms/cubic meter, the pollution level is reached above 75 micrograms/cubic meter, certain harm is caused to human bodies, and the pollution level is severe above 300 micrograms/cubic meter. However, in the present situation, even in spring and summer, which have good air quality, more than 75 of the air quality is still in a normal state, and in autumn and winter, which have heavy haze, the air quality is in a state of more than 300 of the air quality, and people stay indoors for 80% of the time, and indoor purification is imperative. Since PM2.5 is a good carrier for viruses and bacteria, when the air quality index PM2.5 is changed, it means that viruses and bacteria in the air are increased or decreased, so that the sterilization intensity can be adjusted according to the concentration of PM 2.5.
Different sterilization intensities are adopted for different air quality grades, and under the conditions that the higher the air quality grade is, the better the air quality is, the lower the air quality grade is, and the worse the air quality is, the higher the grade of the indoor air quality in the first preset air quality grade classification or the second preset air quality grade classification is, the lower the sterilization intensity of the sterilization module is, and vice versa. In one embodiment, when the indoor user is a preset type of user, the sterilization intensity of the sterilization module is controlled according to a class to which the indoor air quality belongs in a first preset air quality class classification. When the indoor user is not a preset type of user, the sterilization intensity of the sterilization module is controlled according to the level to which the indoor air quality belongs in the second preset air quality level classification.
In one embodiment, the predetermined types of users include the elderly, children, pregnant women. The first preset air quality class classification comprises more than two air quality classes; the second predetermined air quality class classification includes more than two air quality classes. Optionally, the first and second predetermined air quality class classifications include the same number of air quality classes, for example, the same air quality class classification, and the same class in the first and second predetermined air quality class classifications corresponds to different air quality parameter value ranges.
For example, the first preset air quality level classification includes three levels of high, good and poor from high to low, and the second preset air quality level classification also includes three levels of high, good and poor from high to low; the numerical range of the air quality parameter corresponding to each of the first three grades of the high, good and poor air quality grades is different from the numerical range of the air quality parameter corresponding to each of the second three grades of the high, good and poor air quality grades. For example, in the first air quality class, an air quality value M.ltoreq.35 (air quality value is, for example, PM2.5 concentration in units of. mu.g/cubic meter), which represents that the air quality class is good, an air quality value 35 < M.ltoreq.75, which represents that the air quality class is good, an air quality value M > 75, which represents that the air quality class is poor; in the first air quality grade classification, the air quality value M is less than or equal to 66, which represents that the air quality grade is good, the air quality value 66 is greater than or equal to M and less than or equal to 150, which represents that the air quality grade is good, and the air quality value M is greater than 150, which represents that the air quality grade is poor.
Preferably, the corresponding first air quality class is more demanding for a preset type of user. For example, the first and second preset air quality class classifications comprise the same air quality class classification, the air quality requirement of each class in the first air quality class classification being higher than the air quality requirement of the same class in the first air quality class classification. For example, when the air quality parameter value is larger, the air quality is worse, the air quality level is lower, the air quality parameter value is smaller, the air quality is better, and the air quality level is higher (for example, the higher the PM2.5 index indicates that the higher the PM2.5 concentration in the air is, the worse the air quality is), the upper limit value and/or the lower limit value of the air quality parameter value range corresponding to each level in the first preset air quality level class is smaller than the upper limit value and/or the lower limit value of the air quality parameter value range corresponding to the same level in the second preset air quality level class.
In one embodiment, the sterilization module is a UVC (ultraviolet) sterilization module, the sterilization intensity of the UVC sterilization module can be controlled by controlling the current intensity of the sterilization part of the UVC sterilization module, and the light emission intensity (brightness) of the LED lamp, that is, the sterilization intensity of the ultraviolet sterilization can be controlled by controlling the current intensity of the LED lamp of the UVC sterilization module. For example, an adjustable resistor control circuit of the UVC sterilization module is driven by sending signals, an external current adjustable detection resistor is adjusted, the current is changed due to the change of the resistance value of the resistor, the current flowing through the LED is changed, and the brightness is changed accordingly, namely the sterilization intensity is increased when the current is increased. For example, the range of values of the air quality parameter M corresponding to the first air quality class category includes: an air mass value M of 35 or less (M is, for example, PM2.5 concentration in units of. mu.g/cubic meter), an air mass value of 35 or more and M of 75 or less and an air mass value of M of 75 or more; the air quality parameter value ranges corresponding to the second air quality class classification include: the air mass value M is less than or equal to 66, the air mass value 66 is greater than or equal to 150 and the air mass value M is greater than 150. If it is detected that an indoor person is an old person, a child or a pregnant woman (any one or more than two of the old person, the child and the pregnant woman), when the air quality value M is less than or equal to 35, the air quality level is excellent, the LED current can be small, for example, the I is 70mA, the luminous brightness is low, the sterilization capability is relatively weak, and the air quality can still be ensured; when the air quality value is more than 35 and less than or equal to 75, the air quality grade is good, the LED current is adjusted to be 110mA, and medium sterilization capacity is achieved; when M is more than 75, the air quality grade is poor, the LED operates at the maximum current I of 150mA, and the sterilizing capability reaches the highest level. If the old, children and pregnant women are detected to be absent indoors, when the air quality value M is less than or equal to 66, the air quality level is excellent, the LED current can be small, for example, the I is 70mA, the luminous brightness is low, the sterilization capability is relatively weak, and the air quality can still be ensured; when the air quality value is more than 66 and less than or equal to 150, the air quality grade is good, the LED current is adjusted to be 110mA, and medium sterilization capacity is achieved; when M is more than 150, the air quality grade is poor, the LED operates at the maximum current I of 150mA, and the sterilizing capability reaches the highest level.
According to the embodiment of the invention, different air quality grade measurement standards are adopted for different types of users, and sterilization intensity control is performed according to the air quality grade, so that the requirements of different types of users on the air quality can be met. And moreover, the sterilization intensity is controlled according to the air quality grade, so that the power consumption of the air conditioner can be reduced under the condition of ensuring the maximum sterilization capability, and the aim of saving energy is fulfilled.
Optionally, the control unit 130 is further configured to: if the detection unit 110 detects that there is no user in the room, the sterilization module is controlled to operate at a preset sterilization intensity. Preferably, the preset sterilization intensity is lower than the sterilization intensity of the sterilization module during normal sterilization. For example, the sterilization module is a UVC sterilization module, and the current intensity of the sterilization component of the UVC sterilization module is controlled to control the light emission intensity (brightness) of the LED lamp, thereby controlling the sterilization intensity of the UVC sterilization module. For example, if it is detected that there is no user in the room, the LED lamp may be controlled to operate at a preset brightness, where the preset brightness is lower than the brightness of the LED lamp during normal sterilization. When no user is in the room, the sterilization module is controlled to operate at a lower sterilization intensity, so that the power consumption of the air conditioner can be reduced, and the aim of saving energy is fulfilled.
