Referring to FIG. 2, FIG. 2 is a flow chart of an embodiment of a method for controlling an air conditioner according to the present invention.

In this embodiment, the air conditioner based control method includes the following steps:

S10: preset a preset threshold of carbon dioxide concentration in different time zones in each area of the indoor;

S20a: monitoring changes in carbon dioxide concentration in various areas of the room;

S30: detecting outdoor air quality when the carbon dioxide concentration in any area of the indoor is greater than a preset threshold corresponding to the current time point;

S40: Output a fresh air command or an air purifying command according to the detected outdoor air quality and perform corresponding operations.

In this embodiment, the air conditioner-based control method can be used for a smart home system composed of an air conditioner and other home appliances, and can also be used for operation and function control of only the air conditioner. It is known that air conditioners basically include indoor circulation. The system and the outdoor circulation system deliver cooling capacity or heat to the indoor environment through the indoor circulation system and the outdoor circulation system to achieve the purpose of comforting the human body. However, after the air conditioner is operated for a long time, the indoor air quality will deteriorate, to a certain extent. It will endanger human health, so it is necessary to monitor indoor air quality to make an early warning based on changes in indoor air quality to prompt users to improve indoor air quality or to automatically perform certain predetermined operations to improve indoor air quality, as follows:

In order to further improve the control precision of the air conditioner, before the change of the carbon dioxide concentration in each area of the monitoring room, a preset threshold value of the carbon dioxide concentration of each area in the indoor time zone is preset, and the preset threshold value may be provided based on big data or a supplier. On the basis of the technical support, the user can customize the settings. In the custom setting, the corresponding pulse signal can be sent through the remote controller matched with the air conditioner to realize the preset threshold value of the carbon dioxide concentration in different time periods, or through the air conditioner. The interaction interface on the device is set. After the air conditioner obtains the instruction information and the data information input by the user on the interaction interface, the corresponding setting instruction is generated to set the preset threshold of the carbon dioxide concentration in different time periods, different time periods. The division is generally based on the user's living habits, such as according to the user's working time and schedule, and of course, the settings can also be set for the holiday time.

Real-time monitoring of changes in carbon dioxide concentration in various areas of the room through carbon dioxide sensors installed in various areas of the room. The carbon dioxide sensors can be separately installed in various areas of the room, or integrated in households installed in different areas of the room, such as installation in different areas of the room. In the air conditioner internal machine, the carbon dioxide concentration of each area can be monitored by the carbon dioxide sensor integrated in each area of the air conditioner; in other embodiments, after receiving the air conditioner opening command, that is, the air conditioner is activated. After that, the changes in carbon dioxide concentration in various areas of the room are monitored.

When a person uses an air conditioner to deliver cooling capacity or heat to the indoor environment, the person is in a closed environment indoors, and continuously converts oxygen in the indoor closed environment into carbon dioxide output. After a long time, the indoor oxygen concentration decreases and the carbon dioxide concentration increases. When the concentration of carbon dioxide in any area of the room is greater than the preset threshold corresponding to the current time point, it is determined that the concentration of carbon dioxide in the area is too large, which may threaten human health. At this time, it is necessary to increase the concentration of oxygen in the closed environment. Introducing oxygen in an outdoor environment, and creating oxygen in an indoor environment, while the former is relatively more efficient and effective, but first requires outdoor air quality to meet standards and cannot introduce poorer quality air. The current time point selects the preset threshold value of the carbon dioxide concentration applicable to the corresponding time period to determine, which reduces the total power consumption of the home system composed of the air conditioner and other home appliances to a certain extent, and also avoids generating more noise when other home appliances are running. .

The outdoor air quality can be detected by installing an air quality sensor, such as a carbon dioxide sensor or a PM2.5 sensor, in the outdoor unit of the air conditioner, and determining whether the air quality test data meets the preset standard by the air quality sensor feedback data, and When the standard is set, the fresh air command is output to perform the fresh air operation, or the air purification command is output to perform the air purification operation when the preset standard is not met. The preset standard is based on big data acquisition, such as setting the preset standard: the sulfur dioxide content is less than 100ug/m3, nitrogen dioxide content less than 80ug/m3, carbon monoxide content less than 4.0mg/m3, ozone content less than 200ug/m3, PM10 content less than 100ug/m3, PM2.5 content less than 50ug/m3. Of course, in other embodiments, the detection of outdoor air quality can also be obtained by direct air quality data through the cloud.

The air conditioner-based control method of the embodiment can be used for a smart home system composed of an air conditioner and other home appliances, and the carbon dioxide concentration in any area of the room is greater than the preset corresponding to the current time point by monitoring the change of the carbon dioxide concentration in each area of the room. At the threshold value, the outdoor air quality is detected, and the fresh air command or the air purification command is output according to the detected outdoor air quality, and the corresponding fresh air operation or air purification operation is performed to improve the indoor air quality, thereby avoiding the excessive carbon dioxide concentration. Harm caused by human health.

In addition, referring to FIG. 2, when the concentration of carbon dioxide in each area of the monitoring room changes, the control method further includes step S20b: monitoring the concentration of carbon monoxide in each area of the room, and outputting an alarm when the concentration of the carbon monoxide is greater than a third preset threshold. prompt.

In this embodiment, since carbon monoxide is a colorless, odorless, non-irritating gas, and is harmful to human health, it is easy to combine with hemoglobin in the human body to cause suffocation, so in order to better guarantee human life. Safety, when monitoring the change of carbon dioxide concentration in each area of the room, using real-time feedback data of carbon monoxide sensors installed in various areas of the room, real-time monitoring of the concentration of carbon monoxide in various areas of the room, especially when the rate of change of carbon dioxide concentration is faster or more varied. Large area, because in the area where the concentration of carbon dioxide changes greatly, the human body has a relatively large amount of breathing, or a large number of people gather. When the concentration of carbon monoxide in the area is greater than a third preset threshold, an alarm prompt is output, the third preset The threshold value is the maximum concentration of carbon monoxide that the human body can withstand. The alarm prompt may be a voice alarm prompt or a light alarm prompt. When the air conditioner is equipped with a voice module, the voice module may be played through the voice module to prompt the user to move to Ventilation, or output through the display unit of the air conditioner The light flashing light alarm prompt; of course, in other embodiments, a fourth preset threshold smaller than the third preset threshold may be set, and when the carbon monoxide concentration reaches the fourth preset threshold, the control is connected to the air conditioner. The new fan operates to exchange air with the outdoor environment, or when the air conditioner has a fresh air system, the fresh air function is directly turned on and the outdoor environment is ventilated to reduce the carbon monoxide concentration in the area.

Further, referring to FIG. 3, based on the above-described air conditioner-based control method, step S10 specifically includes:

S11: The received user-defined first concentration value is used as a first preset threshold of each area in the first time period, and the user-defined second concentration value is used as the second time period in the indoor area. Two preset thresholds; or,

S12: automatically configure, according to the self-learning data, a first preset threshold of the first time period of each area in the indoor, and a second preset threshold of the second time period.

In this embodiment, when setting preset thresholds of carbon dioxide concentration in different time zones in the indoor area, the user may perform custom setting, or may be automatically configured by the air conditioner based on big data or self-learning data; When the user selects the custom setting, the setting range of the preset threshold provided by the vendor may be obtained in advance, and then the remote controller terminal, the App terminal, etc. matched with the air conditioner are combined according to the setting range, and the division is performed in combination with different time periods. Set the value within the setting range, such as dividing 18:00-22:00 into the first time period, dividing 22:00-07:00 into the second time period, and defining 07:00-18:00 as Working hours, of course, can be specifically set for holidays, such as the holiday period, 07:00-22:00 is divided into the first time period, in the specific operation can also be combined with image monitoring and infrared monitoring indoor human activities for the above time The segment is applicable, that is, the division of the above time period is only applicable to the case where there is a person in the room; of course, it can also be set through the interactive interface of the air conditioner, and the interaction interface is generally pressed. The combination with the display unit may also be a combination of the touch panel and the display unit. The user may input the first concentration value by the button or the touch panel to set the first preset threshold of the first time period, and input the second concentration value. The second preset threshold of the second time period is set.

In addition, in another embodiment, the first preset threshold and the second preset threshold may be automatically configured by the air conditioner based on big data and self-learning data, and the big data may be an air conditioner linked to the supplier. After the cloud server automatically searches for the matching concentration value according to the location information and the time period information as the preset threshold, the first preset of the first time period can be automatically configured according to the recorded user-defined concentration value in different time periods. The threshold value and the second preset threshold value of the second time period are used to determine whether the indoor carbon dioxide concentration exceeds the standard according to the preset threshold value of different time periods, thereby ensuring that the indoor carbon dioxide concentration is always in a harmless range to the human body, thereby ensuring human body comfort and health.

Further, referring to FIG. 4, based on the air conditioner-based control method of the above embodiment, step S20a specifically includes:

S21a: receiving concentration detection data of carbon dioxide fed back by the carbon dioxide sensor every preset time interval;

S22a: Monitor the carbon dioxide concentration and the rate of change of each region in the chamber according to the concentration detection data.

In this embodiment, the carbon dioxide sensor is separately disposed in different areas of the room independently of the air conditioner, and the carbon dioxide sensor is wirelessly connected to the air conditioner, and the concentration monitoring data of the carbon dioxide is fed back to the air conditioner every preset time interval, in other In an embodiment, the air conditioner sends a trigger signal to the carbon dioxide sensor every predetermined time interval, and the carbon dioxide detects the carbon dioxide concentration of the corresponding region after receiving the trigger signal, and then feeds the concentration detection data to the air conditioner; The air conditioner can monitor the carbon dioxide concentration value of each area in the room and the rate of change according to the concentration detection data of the preset time duration of the carbon dioxide sensor, thereby determining whether the carbon dioxide concentration value at the current time point exceeds a preset threshold of the corresponding time period. In addition, by monitoring the rate of change of the carbon dioxide concentration value in each region, it is possible to know the change in the number of people or the change in the state of the human body in each region, so as to control the air conditioner to adjust the operating parameters according to the change in the number of people or the change in the state of the human body;

For example, when the rate of change is greater than a preset rate corresponding to the current time point, the air volume output is increased. When it is detected that the rate of change of the carbon dioxide concentration in a certain area of the room is greater than the preset rate corresponding to the current time point, it can be inferred that the state of the human body activity in the area has changed relative to the previous time period, or the number of people in the area increases. The air conditioner can be controlled to increase the air volume output.

Further, referring to FIG. 5, based on the air conditioner-based control method of the above embodiment, step S30 specifically includes:

S31: determining a time period in which the current time point is located;

S32: detecting outdoor air quality when the concentration of carbon dioxide in any one of the indoor regions is greater than a first preset threshold;
