Fig. 1 is a schematic method diagram of an embodiment of an air conditioner control method provided by the present invention.
As shown in fig. 1, according to an embodiment of the present invention, the air conditioner control method includes at least step S110, step S120, and step S130.
And step S110, detecting the concentration of indoor pollutants and the condition of indoor personnel when the air conditioner is operated.
Specifically, the indoor pollutant concentration is detected by an air quality detection device. The pollutants comprise particulate pollutants (concentration Ct) such as PM2.5 and PM0.3, gaseous pollutants (concentration Pt) such as formaldehyde, VOC and peculiar smell, and/or harmful microorganism pollutants (concentration Mt) such as bacteria and viruses. The air quality detection device comprises a sensor for detecting particle pollutants such as PM2.5, PM0.3 and the like, a sensor for detecting gaseous pollutants such as formaldehyde, VOC, peculiar smell and the like and/or a sensor for detecting the concentration of harmful microorganisms such as bacteria, viruses and the like. The indoor personnel situation may particularly comprise the number of personnel and/or the location of the personnel. The number of persons and/or the position of persons in the room is detected, for example, by means of infrared sensors (e.g., infrared pyroelectric sensors, infrared thermopile sensors) and/or image acquisition devices (e.g., digital cameras).
And step S120, judging whether the indoor environment needs to be purified according to the detected indoor pollutant concentration.
Alternatively, the judgment as to whether the indoor air needs to be purified may be made based on the concentration of one pollutant or the concentrations of two or more pollutants. Optionally, when the detected indoor pollutant only comprises one pollutant, that is, whether the indoor air needs to be purified is judged according to the concentration of the one pollutant, whether the concentration of the pollutant is smaller than a preset concentration threshold corresponding to the pollutant is judged, if the concentration of the pollutant is smaller than the preset concentration threshold corresponding to the pollutant, it is indicated that the indoor air is clean, and it is determined that the indoor air does not need to be purified; and if the concentration of the pollutants is more than or equal to the preset concentration threshold value corresponding to the pollutants, the indoor air is indicated to be dirty, and the indoor air is determined to need to be purified.
Optionally, when the detected indoor contaminant includes only one contaminant, the one contaminant is a particulate contaminant. For example, the particulate pollutant is PM2.5, and whether the indoor air needs to be purified is judged according to the detected PM2.5 concentration, namely whether C is satisfiedt<C, wherein, CtIs the concentration of the particle pollutants, and C is a preset concentration threshold corresponding to the particle pollutants. When C is presentt<When C, determining that the indoor air does not need to be purified, and when CtAnd when the temperature is more than or equal to C, determining that the indoor air needs to be purified.
Optionally, when the detected indoor pollutants include more than two pollutants, that is, whether the indoor air needs to be purified is judged according to the concentrations of the more than two pollutants, whether the concentrations of the more than two pollutants are smaller than respective corresponding preset concentration thresholds is judged, if the concentration of each of the more than two pollutants is smaller than the corresponding preset concentration threshold, it is indicated that the indoor air is clean, and it is determined that the indoor air does not need to be purified; and if the concentration of at least one pollutant in the more than two pollutants is greater than or equal to the corresponding preset concentration threshold value, the indoor air is indicated to be dirty, and the indoor air is determined to need to be purified. Preferably, when the indoor contaminants detected include two or more contaminants, the two or more contaminants include at least particle contaminants.
For example, the contaminants include particulate contaminants, concentration Ct, gaseous contaminants, concentration Pt, and harmful microbial contaminants, concentration Mt. When Ct is less than C, Pt is less than P, and Mt is less than M, the indoor air is clean, and the indoor air is determined not to need to be purified; wherein C is a particulate pollutant concentration judgment standard value, i.e., a preset concentration threshold value corresponding to the particulate pollutant, and optionally, C is 0< C ≦ 0.035mg/m 3. And P is a gaseous pollutant concentration judgment standard value, namely a preset concentration threshold value corresponding to the gaseous pollutant, and optionally, P is more than 0 and less than or equal to 0.03mg/m 3. M is a harmful microorganism pollutant concentration judgment standard value, namely a preset concentration threshold value corresponding to the harmful microorganism pollutant, and is optionally 0< M < 1000 CFU/M3. When Ct is more than or equal to C, Pt and is more than or equal to P and/or Mt is more than or equal to M, the indoor air is indicated to be dirty, and the indoor air needs to be purified.
Step S130, if the indoor air is judged to need to be purified, the ion purification mode is operated according to the indoor personnel condition.
The indoor personnel situation may specifically comprise: number of people and/or location of people. Specifically, if no one is present in the room (the number of people in the room is 0), the ion purification mode is directly operated; if people are in the room, the air sweeping direction of the air conditioner is controlled to avoid the human body when the ion purification mode is operated, or the ion purification mode is directly operated or the ion purification mode is operated after the dust removal operation is performed on the room according to the concentration of the particle pollutants. If the concentration of the particle pollutants is less than the corresponding preset concentration threshold, the ion purification mode is directly operated, and if the concentration of the particle pollutants is greater than or equal to the corresponding preset concentration threshold, the dust removal mode is operated firstly, and then the ion purification mode is operated.
For example, when the room contaminant to be detected includes two or more contaminants, for example, a particulate contaminant, a concentration Ct, a gaseous contaminant, a concentration Pt, and a harmful microbial contaminant, a concentration Mt. When the Ct is more than or equal to C, or the Pt is more than or equal to P, or the Mt is more than or equal to M, the indoor air is indicated to be dirty, the air conditioner needs to be operated for purification, whether the number of indoor personnel is 0 (whether people exist) is further judged, and when the number of indoor personnel is 0 (no people exist indoors), the heavy ions are indicated not to influence the personnel in the ion purification process, the ion purification can be directly operated, and the indoor environment is purified; when it is judged that indoor air needs to be purified but the number of indoor personnel is not 0 (someone is present in a room), the possibility of heavy ion pollution exists in the ion purification execution process, and then the operation mode of the air conditioner needs to be judged according to the concentration condition of particle pollutants. Specifically, when Ct < C, it is indicated that no particulate pollutants exist indoors or the particulate pollutants in rooms are few and can be ignored, the air conditioner directly operates the ion purification and other purification modes, and at the moment, the wind sweeping mode can be judged to be wind-following or wind-avoiding according to the demand condition of target personnel. Namely, the wind sweeping mode of the wind follower or the wind evacuee is executed according to the preset or current selection of the user or intelligent judgment of the user. When Ct is larger than or equal to C, indicating that particulate pollutants exist indoors or more particulate pollutants exist indoors, the problem of heavy ion pollution can be caused when the ion purification mode is operated, the health of indoor personnel is affected, firstly, the dust removal mode is operated to remove the particulate matters, then, the ion purification mode is operated, and at the moment, the air conditioner judges that the air sweeping mode is wind-dependent or wind-dependent according to the requirement condition of target personnel.
When the detected indoor pollutants only comprise one pollutant, such as particle pollutants, and when the Ct is larger than or equal to C and no person exists indoors, the air conditioner operates in a negative ion purification mode; when Ct is larger than or equal to C and people are in the room, the air conditioner operates in a negative ion purification mode, and the air sweeping mode is used for purifying air and avoiding people, so that the problem of heavy ion pollution is solved.
Optionally, if the concentration of the particulate pollutants is greater than or equal to a corresponding preset concentration threshold value, and the air conditioner is currently set to be in an ion purification mode, controlling the air-sweeping and/or controlling the ion purification device of the air conditioner according to the position of indoor personnel. Specifically, whether a person exists in the current wind sweeping range of the air conditioner is judged according to the position of the indoor person; if no person exists in the air sweeping range, controlling the air sweeping direction of the air conditioner according to the current air sweeping mode; if people exist in the wind sweeping range, controlling the wind speed of the air conditioner and/or the ion output quantity of the ion purification device according to the current wind sweeping direction and the indoor personnel position; when the current wind sweeping direction is a fixed wind direction, adjusting the wind sweeping direction to avoid a human body; if the human body cannot be avoided, reducing the wind speed of the air conditioner and/or reducing the ion output quantity; when the current wind sweeping direction is a changing wind direction (namely the wind sweeping direction changes along with time), when the wind sweeping direction is over against a human body, the wind speed of the air conditioner is reduced and/or the ion output quantity is reduced; and when the wind sweeping direction avoids the human body, recovering the wind speed of the air conditioner and/or recovering the ion output quantity.
For example, when Ct is larger than or equal to C, but the air conditioner selects the operation ion purification mode, the air conditioner needs to operate a purified air people-avoiding mode to ensure the health and comfort of indoor personnel, obtain the conditions of the indoor personnel and judge whether personnel exist in the air sweeping range; when the judgment result is no (no person exists in the air sweeping range), the problem that heavy ion pollution is not caused to indoor personnel by the current air sweeping mode is shown, the air conditioner operates the ion purification mode according to the current air sweeping mode, namely, the air sweeping of the air conditioner is controlled according to the current air sweeping mode when the ion purification mode is operated; when the judgment result is yes (people exist in the wind sweeping range), the fact that people exist in the current wind sweeping range is indicated, heavy ion pollution can be generated when the ion purification mode is directly operated, whether the current wind sweeping direction is fixed needs to be further judged, when the wind sweeping direction is judged to be unfixed, the fact that the wind sweeping direction changes at any time is indicated, the problem of heavy ion pollution exists when the wind sweeping direction is over against a human body, at the moment, the air conditioner needs to reduce the wind speed or the ion output quantity to reduce the problem of heavy ion pollution, and the wind speed and the ion output quantity are recovered after the wind sweeping direction avoids the human body. When the judgment result is yes, the wind direction is fixed, whether the adjustment of the wind direction can avoid the human body is further judged (for example, the position of the human body is judged by means of a human body detection device such as a camera and an infrared sensor, the air supply direction and the air supply size of the air conditioner are adjusted according to the air supply range of the air conditioner, so that the air outlet of the air conditioner can avoid the position of the human body), and when the judgment result is yes, the adjustment of the wind direction can avoid the position of the human body, heavy ion pollution is reduced, and the wind direction is adjusted according to the position of indoor personnel to avoid the human body; and if the judgment result is no, the wind direction is adjusted to avoid the position of the human body, and the wind speed or the ion output quantity is reduced to reduce the heavy ion pollution problem.
Optionally, if it is determined that the indoor air does not need to be purified, that is, it is determined that the indoor air does not need to be purified according to the concentration of the indoor pollutants, the air conditioner is controlled to be in standby or the air conditioner is controlled to operate according to the indoor personnel condition. Specifically, if no one is in the room, controlling the air conditioner to stand by; and if people exist in the room, controlling the air conditioner to operate according to the current set wind sweeping mode. The wind sweeping mode comprises wind avoiding and wind following.
For clearly explaining the technical solution of the present invention, the following describes an execution flow of the air conditioner control method provided by the present invention with a specific embodiment.
Fig. 2 is a schematic method diagram of an embodiment of an air conditioner control method according to the present invention. As shown in fig. 2, when the indoor pollutants to be detected include two or more kinds of pollutants, for example, particulate pollutants, concentration Ct, gaseous pollutants, concentration Pt, and harmful microbial pollutants, concentration Mt are included. The air conditioner is electrified to operate, and the air quality detection device is controlled to detect the concentration of indoor pollutants and the personnel condition.

If no person is present in the room, the air conditioner maintains a standby mode. When the Ct is judged to be more than or equal to C, or the Pt is judged to be more than or equal to P, or the Mt is judged to be more than or equal to M, the indoor air is dirty, and the air conditioner needs to be operated for purification, namely, the judgment is yes. Further, when the indoor needs to be purified and the number of indoor personnel is 0, the heavy ions do not influence the personnel in the ion purification process, and the indoor environment can be directly purified by modes such as ion purification and the like; when the indoor needs to be purified and the number of indoor personnel is not 0, the possibility of heavy ion pollution exists in the purification execution process, and the operation mode of the air conditioner needs to be judged according to the pollutant concentration condition. When Ct is less than C, the indoor environment is free of particle pollutants, the air conditioner can directly run in a purification mode such as ion purification, and the like, and the wind sweeping mode is judged to be a mode of following the wind or avoiding people according to the requirement condition of target personnel; namely, the wind sweeping mode of the wind follower or the wind evacuee is executed according to the preset or current selection of the user or intelligent judgment of the user.

And when the judgment result is yes, the wind direction of the air conditioner is fixed, whether the human body can be avoided by adjusting the wind direction of the air conditioner is further judged, namely, the position of the human body is detected, and then the air supply direction and the air supply size of the air conditioner are adjusted according to the air supply range of the air conditioner, so that the air outlet of the air conditioner can be avoided from the position of the human body. When the judgment result is yes, the wind direction is adjusted to avoid the position of the human body, heavy ion pollution is reduced, and the air conditioner adjusts the wind direction according to the position of the human body to avoid the human body; if not, the air conditioner indicates that the position of the human body cannot be avoided by adjusting the wind direction, and the air conditioner needs to reduce the wind speed and/or the ion output quantity to reduce the heavy ion pollution problem.

Fig. 3 is a schematic method diagram of another embodiment of the air conditioner control method according to the present invention. As shown in fig. 3, when the detected indoor pollutants include only more than one type of pollutants, for example, particulate pollutant PM2.5, concentration Ct, the air conditioner is powered on to operate. The PM2.5 sensor is controlled to detect the PM2.5 concentration Ct in the room. The control human detection unit detects the condition of indoor personnel. And judging the operation mode of the air conditioner according to the PM2.5 concentration condition and the indoor personnel condition. Firstly, judging whether purification is needed, when Ct is less than C and no person is in the room, the purification is not needed, and the air conditioner keeps a standby mode; when Ct is less than C and a person is in a room, the air conditioner operates in a normal working mode (such as a cooling mode and a heating mode), and the wind sweeping mode is that the person is carried along with wind or the person is kept away from the wind; when Ct is larger than or equal to C and no one exists indoors, the air conditioner operates in an ion purification mode; when Ct is larger than or equal to C, but a person is in the room, the air conditioner operates in an ion purification mode, and the air sweeping mode is to purify air and avoid people, so that the problem of heavy ion pollution is reduced. And controlling the air conditioner to operate according to the corresponding mode and parameters, detecting the concentration condition of the indoor particulate matters in real time, and adjusting the operation mode and parameters of the air conditioner in time.
Fig. 4 is a block diagram of an embodiment of an air conditioning control apparatus according to the present invention. As shown in fig. 4, the air conditioning control device 100 includes a detection unit 110, a judgment unit 120, and a control unit 130.
The detection unit 110 is used to detect the concentration of indoor pollutants and the condition of indoor personnel when the air conditioner is in operation.
Specifically, the detection unit 110 detects the concentration of indoor pollutants by an air quality detection device. The pollutants comprise particulate pollutants (concentration Ct) such as PM2.5 and PM0.3, gaseous pollutants (concentration Pt) such as formaldehyde, VOC and peculiar smell, and/or harmful microorganism pollutants (concentration Mt) such as bacteria and viruses. The air quality detection device comprises a sensor for detecting particle pollutants such as PM2.5, PM0.3 and the like, a sensor for detecting gaseous pollutants such as formaldehyde, VOC, peculiar smell and the like and/or a sensor for detecting the concentration of harmful microorganisms such as bacteria, viruses and the like. The indoor personnel situation may particularly comprise the number of personnel and/or the location of the personnel. The number of persons and/or the position of persons in the room is detected, for example, by means of infrared sensors (e.g., infrared pyroelectric sensors, infrared thermopile sensors) and/or image acquisition devices (e.g., digital cameras).
The determination unit 120 is configured to determine whether indoor air needs to be purified according to the indoor pollutant concentration detected by the detection unit.
Alternatively, the determination unit 120 may determine whether the indoor air needs to be purified according to the concentration of one pollutant or the concentrations of two or more pollutants. Optionally, when the indoor pollutant detected by the detection unit 110 only includes one pollutant, and when the detected indoor pollutant only includes one pollutant, that is, whether the indoor air needs to be purified is determined according to the concentration of only one pollutant, whether the concentration of the pollutant is less than a preset concentration threshold corresponding to the pollutant is determined, and if the concentration of the pollutant is less than the preset concentration threshold corresponding to the pollutant, it indicates that the indoor air is clean, and it is determined that the indoor air does not need to be purified; and if the concentration of the pollutants is more than or equal to the preset concentration threshold value corresponding to the pollutants, the indoor air is indicated to be dirty, and the indoor air is determined to need to be purified.
Optionally, when the detected indoor contaminant includes only one contaminant, the one contaminant is a particulate contaminant. For example, the particulate pollutant is PM2.5, and whether the indoor air needs to be purified is judged according to the detected PM2.5 concentration, namely whether C is satisfiedt<C, wherein, CtIs the concentration of the particle pollutants, and C is a preset concentration threshold corresponding to the particle pollutants. When C is presentt<When C, determining that the indoor air does not need to be purified, and when CtAnd when the temperature is more than or equal to C, determining that the indoor air needs to be purified.
Optionally, when the indoor pollutants detected by the detection unit 110 include two or more pollutants, when the detected indoor pollutants include two or more pollutants, that is, when it is determined whether the indoor air needs to be purified according to the concentrations of the two or more pollutants, it is determined whether the concentrations of the two or more pollutants are less than the respective corresponding preset concentration thresholds, and if the concentration of each of the two or more pollutants is less than the corresponding preset concentration threshold, it is determined that the indoor air is clean, and it is determined that the indoor air does not need to be purified; and if the concentration of at least one pollutant in the more than two pollutants is greater than or equal to the corresponding preset concentration threshold value, the indoor air is indicated to be dirty, and the indoor air is determined to need to be purified. Preferably, when the indoor contaminants detected include two or more contaminants, the two or more contaminants include at least particle contaminants.
For example, the contaminants include particulate contaminants, concentration Ct, gaseous contaminants, concentration Pt, and harmful microbial contaminants, concentration Mt. When Ct is less than C, Pt is less than P, and Mt is less than M, the indoor air is clean, and the indoor air is determined not to need to be purified; wherein C is a particulate pollutant concentration judgment standard value, i.e., a preset concentration threshold value corresponding to the particulate pollutant, and optionally, C is 0< C ≦ 0.035mg/m 3. And P is a gaseous pollutant concentration judgment standard value, namely a preset concentration threshold value corresponding to the gaseous pollutant, and optionally, P is more than 0 and less than or equal to 0.03mg/m 3. M is a harmful microorganism pollutant concentration judgment standard value, namely a preset concentration threshold value corresponding to the harmful microorganism pollutant, and is optionally 0< M < 1000 CFU/M3. When Ct is more than or equal to C, Pt and is more than or equal to P and/or Mt is more than or equal to M, the indoor air is indicated to be dirty, and the indoor air needs to be purified.
The control unit 130 is configured to operate the ion purification mode according to the indoor personnel condition if the determination unit determines that the indoor air needs to be purified.
The indoor personnel situation may specifically comprise: number of people and/or location of people. Specifically, if no one is present in the room (the number of people in the room is 0), the ion purification mode is directly operated; if people are in the room, the air sweeping direction of the air conditioner is controlled to avoid the human body when the ion purification mode is operated, or the ion purification mode is directly operated or the ion purification mode is operated after the dust removal operation is performed on the room according to the concentration of the particle pollutants. If the concentration of the particle pollutants is less than the corresponding preset concentration threshold, the ion purification mode is directly operated, and if the concentration of the particle pollutants is greater than or equal to the corresponding preset concentration threshold, the dust removal mode is operated firstly, and then the ion purification mode is operated.
For example, when the room contaminant to be detected includes two or more contaminants, for example, a particulate contaminant, a concentration Ct, a gaseous contaminant, a concentration Pt, and a harmful microbial contaminant, a concentration Mt. When the Ct is more than or equal to C, or the Pt is more than or equal to P, or the Mt is more than or equal to M, the indoor air is indicated to be dirty, the air conditioner needs to be operated for purification, whether the number of indoor personnel is 0 (whether people exist) is further judged, and when the number of indoor personnel is 0 (no people exist indoors), the heavy ions are indicated not to influence the personnel in the ion purification process, the ion purification can be directly operated, and the indoor environment is purified; when it is judged that indoor air needs to be purified but the number of indoor personnel is not 0 (someone is present in a room), the possibility of heavy ion pollution exists in the ion purification execution process, and then the operation mode of the air conditioner needs to be judged according to the concentration condition of particle pollutants. Specifically, when Ct < C, it indicates that there is no indoor particulate pollutant or that there are few indoor particulate pollutants and can be ignored, the air conditioner may directly operate the ion purification mode, and at this time, the wind sweeping mode may be determined as the wind follower or the wind catcher according to the demand of the target person, that is, the wind sweeping mode of the wind follower or the wind catcher may be executed according to the user preset or the user current selection or the intelligent determination. When Ct is larger than or equal to C, indicating that particulate pollutants exist indoors or more particulate pollutants exist indoors, the problem of heavy ion pollution can be caused when the ion purification mode is operated, the health of indoor personnel is affected, firstly, the dust removal mode is operated to remove the particulate matters, then, the ion purification mode is operated, and at the moment, the air conditioner judges that the air sweeping mode is wind-dependent or wind-dependent according to the requirement condition of target personnel.
For another example, when the detected indoor pollutant only comprises one pollutant, such as particle pollutant, and when Ct is larger than or equal to C but no person is in the room, the air conditioner operates in the negative ion purification mode; when Ct is larger than or equal to C and people are in the room, the air conditioner operates in a negative ion purification mode, and the air sweeping mode is used for purifying air and avoiding people, so that the problem of heavy ion pollution is solved.
Optionally, the control unit 130 is further configured to: and if the concentration of the particle pollutants is greater than or equal to the corresponding preset concentration threshold value, and the air conditioner is currently set to be in an ion purification mode, controlling the air sweeping and/or controlling the ion purification device of the air conditioner according to the position of indoor personnel.
Specifically, the control unit 130 determines whether there is a person in the current wind sweeping range of the air conditioner according to the position of the person in the room; if no person exists in the air sweeping range, controlling the air sweeping direction of the air conditioner according to the current air sweeping mode; if people exist in the wind sweeping range, controlling the wind speed of the air conditioner and/or the ion output quantity of the ion purification device according to the current wind sweeping direction and the indoor personnel position; when the current wind sweeping direction is a fixed wind direction, adjusting the wind sweeping direction to avoid a human body; if the human body cannot be avoided, reducing the wind speed of the air conditioner and/or reducing the ion output quantity; when the current wind sweeping direction is a changing wind direction (namely the wind sweeping direction changes along with time), when the wind sweeping direction is over against a human body, the wind speed of the air conditioner is reduced and/or the ion output quantity is reduced; and when the wind sweeping direction avoids the human body, recovering the wind speed of the air conditioner and/or recovering the ion output quantity.
For example, when Ct is larger than or equal to C, but the air conditioner selects the operation ion purification mode, the air conditioner needs to operate a purified air people-avoiding mode to ensure the health and comfort of indoor personnel, obtain the conditions of the indoor personnel and judge whether personnel exist in the air sweeping range; when the judgment result is no (no person exists in the air sweeping range), the problem that heavy ion pollution is not caused to indoor personnel by the current air sweeping mode is shown, the air conditioner operates the ion purification mode according to the current air sweeping mode, namely, the air sweeping of the air conditioner is controlled according to the current air sweeping mode when the ion purification mode is operated; when the judgment result is yes (people exist in the wind sweeping range), the fact that people exist in the current wind sweeping range is indicated, heavy ion pollution can be generated when the ion purification mode is directly operated, whether the current wind sweeping direction is fixed needs to be further judged, when the wind sweeping direction is judged to be unfixed, the fact that the wind sweeping direction changes at any time is indicated, the problem of heavy ion pollution exists when the wind sweeping direction is over against a human body, at the moment, the air conditioner needs to reduce the wind speed or the ion output quantity to reduce the problem of heavy ion pollution, and the wind speed and the ion output quantity are recovered after the wind sweeping direction avoids the human body. When the judgment result is yes, the wind direction is fixed, whether the adjustment of the wind direction can avoid the human body is further judged (for example, the position of the human body is judged by means of a human body detection device such as a camera and an infrared sensor, the air supply direction and the air supply size of the air conditioner are adjusted according to the air supply range of the air conditioner, so that the air outlet of the air conditioner can avoid the position of the human body), and when the judgment result is yes, the adjustment of the wind direction can avoid the position of the human body, heavy ion pollution is reduced, and the wind direction is adjusted according to the position of indoor personnel to avoid the human body; and if the judgment result is no, the wind direction is adjusted to avoid the position of the human body, and the wind speed or the ion output quantity is reduced to reduce the heavy ion pollution problem.
Optionally, the control unit 130 is further configured to: if the determination unit 120 determines that the indoor air does not need to be purified, that is, determines that the indoor air does not need to be purified according to the concentration of the indoor pollutants, the air conditioner is controlled to be in standby or the air conditioner is controlled to operate according to the indoor personnel condition. Specifically, if no one is in the room, controlling the air conditioner to stand by; and if people exist in the room, controlling the air conditioner to operate according to the current set wind sweeping mode.
