Background

Air quality is vital to human health, and if people live in a dirty air environment for a long time, visceral tissues of people can be damaged, respiratory diseases and allergic reactions can be caused, and the incidence rate of leukemia and cancer can be increased. The harm to sensitive people such as pregnant women and children is more serious. Bacteria are easy to breed in the environment with the air not circulating, the harm to the health of human bodies is great, and the biological hazards of cockroaches, ants, mites and the like can also appear in the sultry and humid environment. The lack of ventilation for a long time can also lead to low oxygen content in the air, possibly cause cerebral anoxia and further cause dizziness. If sneezing frequently occurs, the throat is uncomfortable, foreign body sensation occurs, and the breathing is not smooth, which is very likely to be the reason for poor air quality.

However, in the prior art, the cleaning system of the air conditioner can only be adjusted according to the indoor environment, and the cleaning function is started only after the indoor environment is monitored to be polluted. This means that the user is passively exposed to the contaminated environment before the air conditioner begins its decontamination operation. Meanwhile, since the house has some gaps, when the outside environment is dirty, some air pollutants may flow into the room from the windows, the window gaps, and the like.

The time point and the time interval until the air pollution appears outside the room are predicted, and the air purification work is performed in advance before the quality of the air outside the room is deteriorated. The technical scheme disclosed in this application can strengthen the purifying effect to indoor air effectively.

The method for controlling indoor air quality provided by the embodiment of the application is described below with reference to fig. 1. As shown in fig. 1, one of the methods for controlling indoor air quality includes:

and S01, the air conditioning system obtains the abnormal time point of the abnormal air quality according to the air forecast information of the current day.

In the embodiments of the present application, the air quality abnormality refers to a case where air pollution occurs.

And acquiring current temperature, humidity and air quality information through application software. Meanwhile, the air conditioning system confirms the time when the air pollution condition occurs in the future as an abnormal time point when the air quality is abnormal.

And S02, the air conditioning system corrects the abnormal time point according to the historical weather forecast information to obtain a target time point.

In the embodiment of the application, the air conditioning system corrects the time of the air pollution condition in the current weather forecast based on the time of the air pollution condition in the historical weather forecast information. Therefore, the pollution time provided by the current weather forecast can be further optimized, and a more accurate time point of the air pollution condition can be obtained.

And S03, the air conditioning system obtains the target time period according to the difference value between the current time and the target time.

Therefore, the air conditioning system can obtain the time interval from the current time to the occurrence of the air pollution condition, and provides a time basis for the subsequent air purification work.

And S04, the air conditioning system controls the air conditioning system to purify fresh air based on the target time period and the indoor environment information.

In an embodiment of the present application, the indoor environment information may include indoor air quality information, and indoor personnel information.

Like this, the technical scheme of this application can obtain air quality condition, indoor air quality and the indoor personnel condition of a period of time in the future based on weather information, and the air purification operation of autonomically carrying out. The time point and the time interval until the air pollution appears outside the room are predicted, and the air purification work is performed in advance before the quality of the air outside the room is deteriorated. The technical scheme disclosed in the application can strengthen air conditioning system to the purifying effect of room air effectively.

The following describes a method for correcting an abnormal time point according to historical weather forecast information to obtain a target time point, with reference to fig. 2. As shown in fig. 2, the method for correcting the abnormal time point according to the historical weather forecast information to obtain the target time point includes:

s201, the air conditioning system acquires a plurality of historical weather forecast information and historical weather actual information which are the same as the current date in the past year.

In the embodiment of the application, the air conditioning system acquires the actual air quality information of the same date as the current date and the weather forecast information of the current date in the previous years from the history database. Because the climate conditions are similar for the same area on the same date, a large amount of sample information can be obtained for time correction.

S202, the air conditioning system obtains a prediction time point of the air quality abnormity in the plurality of historical weather forecast information.

In the embodiment of the present application, the air conditioning system extracts a time point at which an air pollution situation occurs in the historical weather forecast information from the information center obtained in the previous step. I.e. the time point in the weather forecast on the historical date at which the air pollution situation is predicted to occur. In this case, the more past year samples are obtained, the more accurate the subsequent precision correction work is.

S203, the air conditioning system acquires actual time points of air quality abnormity in the plurality of historical weather actual information.

In an embodiment of the present application, the air conditioning system may extract a real time point at which the air pollution situation actually occurs on the past date from the weather database. Similarly, the more past year samples are obtained, the more accurate the subsequent precision correction work is.

And S204, calculating the time difference between the predicted time point and the actual time point of each year by the air conditioning system.

For example, if the weather forecast of the historical date predicts that the air pollution condition occurs at 15:00 of the day, the actual time of the air pollution occurs at 14:50 of the day. The time difference is 10 minutes ahead, and the time difference can be determined to be-10 minutes.

And S205, the air conditioning system calculates the average value of the time differences of the previous years and the current date as a correction value.

In the embodiment of the application, the acquired time differences of all the years are summarized and averaged to obtain the time correction value of the weather forecast.

S206, the air conditioning system corrects the abnormal time point based on the correction value to obtain a target time point.

In the embodiment of the application, if the correction value obtained in the last step is 5 minutes ahead, and the time of the occurrence of the pollutants is predicted to be 13:15 by the current weather forecast, the current predicted time is corrected by using the correction value, so that the target time point of the occurrence of the pollution is 13: 10.

Therefore, the current weather forecast information is corrected through the historical information, and the accuracy of the air quality prediction work can be effectively improved.

Preferably, the air quality anomaly may be refined. In embodiments of the present application, the Air Quality anomalies may be classified into a first Air anomaly and a second Air anomaly based on an Air Quality Index (AQI). When the AQI is at a first threshold, a current air quality anomaly is determined as a first air anomaly. When the AQI is at a second threshold, the current air quality anomaly is determined to be a second air anomaly.

In an embodiment of the present application, the first air anomaly refers to mild or moderate pollution, and the first threshold value may be set to 100 to 200. The second air anomaly refers to heavy or severe pollution, and the second threshold value may be set to 200 or more. In practical situations, the user or the manufacturer may set the values of the first threshold and the second threshold according to practical situations. If the user has a high requirement for air quality, the threshold value may be set to be relatively small.

Another method for controlling indoor air quality provided by the embodiment of the present application is described below with reference to fig. 3. As shown in fig. 3, a second method for controlling indoor air quality includes:

s301, the air conditioning system obtains an abnormal time point of the abnormal air quality according to the weather forecast information of the day.

And S302, the air conditioning system corrects the abnormal time point according to the historical weather forecast information to obtain a target time point.

And S303, the air conditioning system obtains a target time period according to the difference value between the current time and the target time.

S304, the air conditioning system is used for linking the intelligent door and window and the intelligent curtain to be in an opening or closing state based on the relation between the target time period and a preset first time threshold value.

In the embodiment of the application, the first time threshold refers to how long before air pollution, the smart windows and the smart curtains are closed to stop ventilation of the windows and the doors. The specific numerical value can be set by the user according to the actual situation.

In actual work, when the target time period is less than or equal to the preset first time threshold, the air conditioning system is linked with the intelligent door and window and the intelligent curtain to be closed through the wireless network. Meanwhile, the user is reminded through software such as a mobile phone application program. If the user only has one of the intelligent door and window or the intelligent curtain, the intelligent door and window or the intelligent curtain is linked to be closed so as to play a role in intercepting air pollutants.

S305, the air conditioning system controls the air conditioning system to purify fresh air based on the target time period and the indoor environment information.

Like this, the technical scheme of this application can obtain air quality condition, indoor air quality and the indoor personnel condition of a period of time in the future based on weather information, and the air purification operation of autonomically carrying out. The time point and the time interval until the air pollution appears outside the room are predicted, and the air purification work is performed in advance before the quality of the air outside the room is deteriorated. Meanwhile, aiming at the condition of air pollution to be generated, the ventilation control logic of the door and the window is adjusted. Before air pollution occurs, based on the intelligent door and window and the intelligent curtain, ventilation is closed in advance, and external air pollutants are prevented from entering the indoor environment. The technical scheme disclosed in the application can effectively enhance the management of the indoor air environment and improve the user experience.

Another method for controlling indoor air quality provided by the embodiment of the present application is described below with reference to fig. 4. As shown in fig. 4, a third method for controlling indoor air quality includes:

s401, the air conditioning system obtains an abnormal time point of the abnormal air quality according to the weather forecast information of the day.

S402, the air conditioning system corrects the abnormal time point according to the historical weather forecast information to obtain a target time point.

And S403, the air conditioning system obtains a target time period according to the difference value between the current time and the target time.

And S404, the air conditioning system obtains current temperature and humidity information according to the current weather forecast information.

S405, the air conditioning system links the intelligent door and window and the intelligent curtain to be in an opening or closing state based on the relation between the target time period and a preset first time threshold value.

S406, the air conditioning system links the intelligent door and window and the intelligent curtain to be in an opening or closing state based on the relation between the target time period and a preset first time threshold value.

S407, the air conditioning system controls the air conditioning system to purify fresh air based on the target time period and the indoor environment information.

Specifically, air conditioning equipment links smart door and window and intelligent (window) curtain and is in the state of opening or closing based on the relation of target time quantum and predetermined first time threshold value, includes:

and judging by the air conditioning system, and linking the intelligent door and window and the intelligent curtain to be in an open state under the conditions that the target time period is greater than the first time threshold and the temperature and humidity information meets the temperature and humidity threshold.

In the embodiment of the application, when the humiture threshold value is used for judging the external temperature and humidity and satisfies what condition, windowing ventilation can be carried out. Before air conditioning systems leave a factory, the temperature and humidity threshold is usually set to be in the range of-8 ℃ to 26 ℃ and the outdoor humidity is between 40% and 60%. The user may further set a specific numerical value. Thus, when the time difference between the time when the air pollution occurs and the current time meets the first time threshold and the outdoor condition meets the temperature and humidity threshold. The air conditioning system links the intelligent door and window and the intelligent curtain to be in an opening state, and keeps ventilation.

And judging by the air conditioning system, and linking the intelligent door and window and the intelligent curtain to be in a closed state when the target time period is less than or equal to the first time threshold value or the temperature and humidity information does not meet the temperature and humidity threshold value.

In this way, when the time difference between the time when the air pollution occurs and the current time does not satisfy the first time threshold or the outdoor condition does not satisfy the temperature and humidity threshold. The air conditioning system is linked with the intelligent door and window and the intelligent curtain to be in a closed state, so that the outdoor air is prevented from polluting the indoor environment.

The technical scheme of this application can obtain the air quality condition, indoor air quality and the indoor personnel condition of a period of time in the future based on weather information, and the air purification operation of autonomically carrying out. The time point and the time interval until the air pollution appears outside the room are predicted, and the air purification work is performed in advance before the quality of the air outside the room is deteriorated. Meanwhile, the door and window ventilation control logic is adjusted according to whether the air pollution condition and the outdoor temperature and humidity meet the preset conditions. Before air pollution occurs, based on the intelligent door and window and the intelligent curtain, ventilation is closed in advance, and external air pollutants are prevented from entering the indoor environment. And when the outdoor temperature and humidity environment is appropriate and the air quality is good, window opening ventilation can be performed to improve the indoor air quality. The technical scheme disclosed in the application can effectively enhance the management of the indoor air environment and improve the user experience.

The method for controlling the air conditioning system to perform fresh air purification based on the target time period and the indoor environment information provided by the embodiment of the application is described below with reference to fig. 5. As shown in fig. 5, controlling the air conditioning system to perform fresh air purification based on the target time period and the indoor environment information includes:

s501, the air conditioning system detects whether a person exists in the room.

In the embodiment of this application, air conditioning system can catch effective clear image from different angles different position through the linkage camera to judge whether indoor personnel exist.

And S502, judging by the air conditioning system, and under the conditions that the target time period is less than or equal to a preset time threshold, first air abnormality occurs outdoors, the indoor air condition is not excellent and people exist indoors, enabling the air conditioning system to perform a high-speed air purification mode.

In the embodiment of the present application, the preset time threshold refers to how long before the air conditioning system starts the air cleaning operation before the air is polluted. Meanwhile, the indoor air condition can be detected and acquired by the indoor air sensor. When the target time period is less than or equal to the preset time threshold, the first air is abnormal outdoors, the indoor air condition is not good and people exist indoors, the air conditioning system is enabled to carry out a high-speed air purification mode, and the indoor environment is rapidly purified. When the indoor environment sensor detects that the indoor air AQI is excellent, the operation is switched to low wind.

And S503, judging by the air conditioning system, and under the conditions that the target time period is less than or equal to a preset time threshold, first air is abnormal outdoors, the indoor air condition is not excellent and no person exists indoors, enabling the air conditioning system to perform a low-rate air purification mode after the first time period.

Here, the preset time threshold is smaller than the target time period.

And S504, judging by the air conditioning system, and under the conditions that the target time period is less than or equal to a preset time threshold, the second air is abnormal outdoors, the indoor air condition is not excellent and no person is indoors, enabling the air conditioning system to perform a low-speed air purification mode.

At this time, the air conditioning system only needs to purify air at a low rate, and the negative pressure of the air conditioning system makes more air in the room participate in exchange. Before outdoor pollution occurs, the low-speed gear can completely purify the indoor space once and save energy.

Therefore, the air conditioning system can select proper air purification execution logic according to indoor air quality conditions and personnel conditions, and further enhance the efficiency of indoor air purification work.

The following describes a method for acquiring the first time period provided in the embodiment of the present application with reference to fig. 6. As shown in fig. 6, a method of acquiring a first time period, comprising:

s601, the air conditioning system acquires the clean air output ratio of the current air conditioning system.

And S602, the air conditioning system determines the purification time required by the air conditioning system to complete the purification of the air of the house based on the output ratio of the clean air.

In the embodiment of the present application, the purification time required for the current air conditioner to complete the whole room air purification work may be determined according to the clean air output rate of the air conditioner operation and the room spatial information.

And S603, the air conditioning system calculates the difference between the target time period and the purification time to obtain a first time period.

Thus, the air conditioning system can complete the indoor air purification before the outdoor air pollution occurs. The air conditioning system is prevented from carrying out air purification work under the condition of outdoor pollution, and outdoor pollutants are prevented from entering. Thereby ensuring that the air in the room is always in a clean state and reducing the deposition and adhesion of dust in the room. Meanwhile, the air conditioning system can complete the indoor air purification in the shortest time. The air purification work that continues under indoor unmanned condition has been avoided, lead to the system energy consumption too high.

Next, a practical working flow of the method for controlling indoor air quality according to the present embodiment will be described:

the air conditioning system is connected to intelligent equipment (such as a mobile phone, a sound box and the like) through wireless network communication and the like, and related information such as weather temperature, humidity, air quality index and the like in weather application software on the equipment is automatically retrieved. And acquiring current temperature, humidity and air quality information through application software. Meanwhile, the air conditioning system confirms the time when the air pollution condition occurs in the future as an abnormal time point when the air quality is abnormal. For example, the air quality index of the air conditioning system can rise to 150 when the air conditioning system acquires the air at 15:00 today. And the air quality index 150 is within a preset first threshold, the air conditioning system determines that 15:00 is an abnormal time point and the abnormal condition is a first air abnormality.

The air conditioning system acquires the actual air quality condition of the same date as the current date and the weather forecast information of the current date in the previous years from the historical database. If the current date is 5 months and 1 days, the air conditioning system calls historical weather forecast information of 5 months and 1 days of years before, and determines the time point of the abnormal air quality on the same date in the past year. For example, the time points at which the air quality abnormality occurs in the historical weather forecast information 5 years before deployment are 8:03, 16:15, 5:20, 7:20, and 13:00, respectively. And the predicted time points of the occurrence of the air quality abnormality in the past weather forecast are 8:15, 16:05, 5:25, 7:30 and 13: 05. From this, the time differences of the years were calculated as 12 minutes later, 10 minutes earlier, 5 minutes later, 10 minutes later and 5 minutes later, respectively. The correction value thus obtained was delayed by 4.4 minutes. And correcting the abnormal time point based on the correction value to obtain the target time point of 15: 04.

If the time at this time is 13:00, the target time period is 2 hours and 4 minutes.

If the currently set first time threshold is 1 hour, the current temperature is measured as 20 degrees and the humidity is measured as 50%. And the humidity threshold value set by the user is 15-20 ℃ and the humidity is 40-60%, and the air conditioning system is linked with the intelligent door and window and the intelligent curtain to keep an open state. And when the air conditioner system reaches 14:04, the intelligent door and window and the intelligent curtain are linked to be in a closed state.

If the humidity threshold set by the user is 21-25 ℃ and the humidity is 60-80%, the air-conditioning system is in a closed state by linking the intelligent door and window and the intelligent curtain. Meanwhile, the air conditioning system also sends prompt information to the user, and the user manually closes the window when the user does not have the intelligent window or door or intelligent curtain.

Then, the air conditioning system selects an air purification execution logic based on the current indoor air quality situation and the indoor personnel situation.

When the preset time threshold preset by the user is 1 hour, the indoor air quality is poor and people exist indoors, the air conditioning system starts air purification work at a rate of 14: 04. At this time, the air conditioning system turns on the high-rate air purification mode, and when the indoor air quality is excellent, the air conditioning system turns on the low-rate air purification mode to save energy.

When the preset time threshold preset by the user is 1 hour, the indoor air quality is not good and no person exists indoors. The air conditioning system determines a purification time required for purifying the room air to be half an hour based on the acquired output ratio of the clean air. While the current time was 14:00 and the time difference to the target time point was 1 hour and 4 minutes. The calculated first time period is 34 minutes, then the air conditioning system begins the low rate air purification mode when 14: 34.

If the first threshold value set by the user is 100 to 120 and the second threshold value is 121 to 200, it is determined that the outdoor air condition is the second air abnormality. When the indoor air quality is not good and no person is present in the room, the air conditioning system performs the low rate air cleaning mode at 14: 04.

The method for controlling indoor air quality further comprises a self-cleaning method of the air conditioner. The following describes a method for self-cleaning an air conditioner provided in an embodiment of the present application with reference to fig. 7. As shown in fig. 7, a method of self-cleaning of an air conditioner, includes:

s701, the air conditioning system acquires the air condition of the current region and the indoor personnel condition.

S702, the air conditioning system controls the air conditioner to start a self-cleaning function based on the running condition of the air conditioner, the condition of indoor personnel and the air condition of the current region.

When the air conditioning system is heavily polluted or seriously polluted, a plurality of pollutants are accumulated in the air conditioner by air purification, and when the air conditioning system is operated under the working conditions for a long time, the indoor air quality is polluted. Therefore, when the air conditioning system is used for purifying air when the air is seriously polluted or seriously polluted, the air conditioning system needs to be automatically cleaned in time. Users often forget to self-clean the air conditioner due to busy work and life and other reasons, and a large amount of pollutants are accumulated in the air conditioner over time. The air conditioner operates under the working condition for a long time, and the indoor air quality is seriously influenced. The technical scheme that this application provided can carry out the air conditioner automatically cleaning according to actual conditions, can effectively avoid above-mentioned problem to take place.

Specifically, if the second air abnormality occurs outdoors when the air conditioner is started for the last time to perform the purification or fresh air function and no person is in the room, the self-cleaning of the air conditioner is started.

In embodiments of the present application, the air heavy or severe pollution is typically determined as the second air anomaly. When confirming that no person is in the room, the self-cleaning of the air conditioner is started, and the influence on the comfort level of the person in the room caused by the self-cleaning of the air conditioner under the condition that the person is in the room is avoided.

And if the first air abnormity occurs outdoors when the purification or fresh air function is started for the target times before the air conditioner and no personnel exists indoors, the self-cleaning of the air conditioner is started.

In the embodiments of the present application, the light pollution or the medium pollution of the air is generally determined as the first air abnormality. The preset target times can be determined by a user according to actual conditions, and the target times can be set to be smaller values when the requirement on the indoor air quality is higher.

Next, an actual work flow of the method for self-cleaning an air conditioner provided in this embodiment is described:

when the air conditioning system confirms that the current air quality is good and no personnel exist indoors based on weather forecast information, if the outdoor air is severely polluted when the air conditioning system starts air purification work last time, the air conditioning system starts self-cleaning.

When the target number is set to 3. When the air conditioning system confirms that the current air quality is good and no personnel exist indoors based on weather forecast information, if the outdoor air is subjected to medium-light air pollution when the air conditioner starts air purification work for the previous 3 times, the self-cleaning of the air conditioner is started.
