[0058] First, the terms involved in the present application are explained.

[0059] API: Application Programming Interface, an application programming interface, is a protocol that allows communication between different software systems; in a smart home system, API can be used to obtain outdoor air quality data from public air quality data providers.

[0065] With the progress of science and technology and the improvement of people's living standards, the comfort and health of the living environment are also concerned by users, and fresh air equipment has gradually become a product that attracts attention in the market.

[0066] Fresh air handling unit as an important part of fresh air equipment, and fresh air handling unit focuses on providing continuous and efficient fresh air supply, through advanced filtration technology and reasonable air flow organization, effectively improving indoor air quality, reducing harmful substances, increasing oxygen content, and creating a healthier living environment for users.

[0067] However, manual control of fresh air handling unit depends on the initiative of users, which requires frequent intervention and adjustment of users, increasing the complexity of maintenance and management; in addition, manual control may cause the fresh air handling unit to run excessively or insufficiently, affecting the energy utilization efficiency of fresh air equipment.

[0068] To solve the above problems, the application provides a control method for fresh air handling unit.

[0069] Firstly, the implementation scenario involved in the present application is described.

[0070] In one implementation scenario, a fresh air control module is arranged in the intelligent fresh air equipment, and the fresh air control module stores a fresh air control logic based on indoor and outdoor environment information and the location of the intelligent fresh air equipment; the fresh air control module includes an air quality detection sensor and a human body detection sensor, the air quality detection sensor can detect the air quality of the indoor environment in real time, and the human body detection sensor can detect whether a user is in the fresh air area corresponding to the fresh air equipment.

[0071] For example, the intelligent fresh air equipment obtains indoor air quality information in real time through the air quality detection sensor and the human body detection sensor arranged therein, and determines whether a user is present in the corresponding fresh air area at present; based on the Internet of Things where the intelligent fresh air equipment is located, the outdoor air quality information of the location where the intelligent fresh air equipment is located is obtained in real time; the fresh air control module determines the corresponding fresh air control decision based on the real-time obtained indoor and outdoor air quality information and the determination result of whether a user is present in the corresponding fresh air area, specifically, the fresh air control module can dynamically adjust the start and stop threshold of the fresh air unit based on the outdoor and indoor air quality information and the location information, to realize intelligent control of the fresh air function.

[0072] In another implementation scenario, the fresh air control module can also be arranged in other intelligent devices in the same home Internet of Things as the intelligent fresh air equipment, specifically, it can be a duct unit; the duct unit is responsible for adjusting the temperature and humidity of indoor air, and uniformly distributes the processed air to each room through a complex duct system to ensure that each corner can enjoy suitable temperature and humidity conditions.

[0073] For example, Figure 1 is a scene diagram of the control method of the fresh air machine provided by the present application, and the control method of the fresh air machine provided by the present application is applied to Figure 1 the linkage control of the fresh air unit and the duct unit as shown in Figure 1 The fresh air unit (i.e. fresh air equipment) and the duct unit are in communication connection, the fresh air control module is arranged in the duct unit, and the duct unit is provided with an air quality detection sensor and a human body detection sensor, and the duct unit can also obtain outdoor air quality; the fresh air control module in the duct unit determines the fresh air control logic based on the obtained indoor and outdoor air quality and the information whether a user is present in the indoor area at present, and when the determination result is to start the fresh air unit, the duct unit sends a control instruction to the fresh air unit to control the operation of the fresh air unit, so as to improve the indoor air quality. The present application does not specially limit the obtaining method of the outdoor air quality information.

[0074] The application does not specially limit the setting position of the fresh air control module. The following embodiments take the setting of the fresh air control module in the intelligent fresh air equipment as an example for detailed description.

[0075] The control method of the fresh air unit provided by the application acquires the position information of the fresh air equipment and the indoor and outdoor air quality information, dynamically adjusts the start and stop thresholds of the fresh air equipment based on the obtained information, detects whether there is a person in the room through a human body detection sensor, controls the fresh air equipment to start under the condition that there is a person in the room, ensures that the indoor air quality is always in a good state, and improves the comfort and health level of the user. The method is suitable for different geographical environments and air quality conditions, can more accurately control the operation of the fresh air equipment through dynamic adjustment of the start and stop thresholds and human sensing detection, provides a more flexible fresh air control strategy, avoids excessive operation or insufficient operation of the fresh air equipment, optimizes the energy utilization efficiency, and improves the operation efficiency of the fresh air equipment and the user experience.

[0076] The technical solutions of the application and how the technical solutions of the application solve the above technical problems will be described in detail in the following specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the application will be described below with reference to the drawings.

[0077] Figure 2 Flowchart of the control method of the fresh air unit provided by the embodiment of the application Figure 1 The execution subject of the embodiment can be, for example, an intelligent fresh air equipment provided with a fresh air control module. As shown in Figure 2 The control method of the fresh air unit provided by the embodiment includes the following steps.

[0078] S201: Acquire first air quality information of the outdoor environment and first position information of the house.

[0079] The first air quality information is used to indicate the air quality data of the outdoor environment acquired through a sensor or other detection equipment, and the first position information is used to indicate the geographical position information of the intelligent fresh air equipment.

[0080] It can be understood that the air quality information usually includes multiple quality indicators, and the multiple quality indicators collectively reflect the overall quality condition of the air. Since the air quality of different geographical positions is different, and the difference in the air quality of different geographical positions is the result of the joint action of multiple factors, the operation mode of the fresh air control logic is dynamically adjusted according to the air quality characteristics of different geographical positions, so as to provide a more healthy and comfortable living environment for the user.

[0081] For example, the first air quality information is usually obtained by an external sensor or by accessing a public air quality API, and specifically refers to particulate matter concentrations such as PM2.5 and PM10, and other factors that may affect air health (such as CO2, VOCs, etc.); the first location information specifically includes: smart fresh air equipment A-geographic coordinates A, environmental characteristics A, and climate conditions A. The content of the first location information is not specially limited in this application.

[0082] S202: Determine the start threshold of the fresh air unit based on the first air quality information and the first location information.

[0083] The start threshold is used to indicate the air quality threshold that the indoor air quality needs to reach before the fresh air unit starts running.

[0084] It can be understood that, due to the differences in air quality at different geographic locations, real-time air quality data corresponding to the first location information can be obtained according to the specific geographic location of the current smart fresh air equipment, i.e., the first location information. The first location information of different smart fresh air equipment is managed and optimized in a regional manner for the fresh air control logic, for example, a stricter start threshold is set in a high-pollution area, and the threshold is appropriately relaxed in a low-pollution area, and the high-pollution area and the low-pollution area are divided according to outdoor air quality.

[0085] Specifically, when the outdoor air quality is poor, the indoor air quality has the possibility of decreasing after the introduction of outdoor air. Therefore, in order to ensure that the indoor air quality remains at a healthy level, the fresh air unit needs to be started more frequently to timely discharge indoor pollutants while minimizing the introduction of outdoor pollutants. That is, by lowering the start threshold, the fresh air unit will start when the indoor air quality is poor, thereby recovering the indoor air quality more quickly. When the outdoor air quality is good, the possibility of decreasing the indoor air quality after the introduction of outdoor air is low. At this time, the start threshold can be appropriately increased to reduce the start frequency of the fresh air unit, thereby ensuring the indoor air quality while reducing unnecessary energy consumption.

[0086] Optionally, the fresh air control module pre-stores a plurality of start thresholds, and each first location information has a unique corresponding start threshold under different first air quality information. The fresh air control module can automatically select and apply the corresponding start threshold according to the real-time first location information and first air quality information, thereby realizing intelligent and regional management of the start and stop process of the fresh air unit and ensuring that good air quality and energy efficiency are provided for users under different environmental conditions.

[0087] The multiple start thresholds stored in the fresh air control module can be determined based on historical first air quality data, geographical location characteristics, user health needs, and environmental standards, etc. By analyzing long-term air quality records in a specific region, considering the influence of geographical environment on air quality, combining the health requirements of the target user group, and referring to relevant international and domestic air quality standards, intelligent algorithms and machine learning techniques are used for optimization to ensure that the fresh air system is started at the appropriate time to provide a healthy and comfortable indoor air environment for users.

[0088] According to the current acquired first position information and first air quality information, matching processing is performed with the multiple start thresholds pre-stored in the intelligent fresh air equipment, the threshold with the highest matching degree is determined, and the threshold is taken as the start threshold of the fresh air unit in the intelligent fresh air equipment.

[0089] For example, for the central area of city A, when the indoor air quality detection data acquired by the intelligent fresh air equipment indicates that the CO2 concentration reaches 800 ppm, the fresh air unit will automatically start; and for the suburbs of city A, the fresh air unit will start when the CO2 concentration reaches 1200 ppm; if the geographical coordinates A of the intelligent fresh air equipment A correspond to the central area of city A, the start threshold of the fresh air unit in the intelligent fresh air equipment A is: CO2 concentration 800 ppm; if the geographical coordinates A of the intelligent fresh air equipment A correspond to the suburbs of city A, the start threshold of the fresh air unit in the intelligent fresh air equipment A is: CO2 concentration 1200 ppm. The determination of the start threshold in the present application is not specially limited, and the quality index corresponding to the start threshold is not specially limited.

[0090] S203: Acquire second air quality information of the indoor environment, and in the case that the second air quality information is greater than or equal to the start threshold, detect whether there is a person in the indoor environment, and if there is a person in the indoor environment, control the fresh air unit to start.

[0091] The second air quality information is used to indicate the air quality data of the indoor environment acquired by a sensor or other detection equipment.

[0092] It can be understood that in the case that the second air quality information is greater than or equal to the start threshold, the air quality in the indoor environment has reached a pre-set poor level, and measures need to be taken to improve it; at this time, the geographical position of the precision acquisition equipment can be accurately acquired, and the real-time air quality data can be combined to realize intelligent control of the fresh air function and provide a more healthy and comfortable living environment for users.

[0093] The second air quality information in the room is acquired in real time by using the air quality detection sensor, and in the case that the second air quality information is greater than or equal to the starting threshold, the human body detection sensor is used to detect whether there is a person in the indoor environment where the fresh air handling unit is currently located, if there is a person in the room, it indicates that the space is being used, and the air quality has actual demand of the indoor personnel, at this time, the fresh air handling unit is controlled to start to improve the indoor air quality.

[0094] For example, the starting threshold of the current intelligent fresh air equipment can be 800 ppm, the second air quality information in the room is acquired in real time, that is, the CO2 concentration in the room is acquired in real time, if the current acquired CO2 concentration in the room is 900 ppm, that is, the current CO2 concentration is higher than the starting threshold, at this time, the human body detection sensor is controlled to confirm whether there is a person in the room, and in the case that there is a person in the room, the fresh air function is started to introduce fresh air and filter indoor pollutants to improve the indoor air quality.

[0095] The control method of the fresh air handling unit provided in the embodiment determines the starting threshold of the fresh air handling unit by acquiring the first air quality information of the outdoor and the first location information of the house, and determines the starting threshold of the fresh air handling unit based on the first air quality information and the first location information; the second air quality information in the room is acquired, and in the case that the second air quality information is greater than or equal to the starting threshold, whether there is a person in the room is detected, and if there is a person in the room, the fresh air handling unit is controlled to start. The method can adapt to different geographical environment and air quality conditions, provide more flexible control strategy, and improve the operation efficiency and user experience of the fresh air handling unit.

[0096] Figure 3 The flowchart of the control method of the fresh air handling unit provided in the embodiment Figure 2 . As Figure 3 shown, the embodiment is based on Figure 2 the embodiment, and the control method of the fresh air handling unit is described in detail, the control method of the fresh air handling unit shown in the embodiment comprises:

[0097] S301: acquiring the first air quality information of the outdoor and the first location information of the house.

[0098] Step S301 is similar to step S201 described above, and will not be described here.

[0099] S302: determining a first corresponding relationship between the outdoor air quality and the starting threshold of the fresh air handling unit based on the first location information.

[0100] S303: determining the starting threshold based on the first air quality information and the first corresponding relationship.

[0101] It can be understood that the first corresponding relationship refers to a mapping or association between outdoor air quality (environmental quality corresponding to the geographical position determined by the first position information) and the fresh air handling unit start threshold; the first corresponding relationship indicates the standard or condition to be reached for the fresh air handling unit to start under different outdoor air quality conditions, so as to achieve the purpose of optimizing indoor air quality. For example, when the outdoor air quality is poor, the start threshold may be lowered to make the fresh air handling unit start more easily, so as to improve the indoor air quality faster; on the contrary, when the outdoor air quality is good, the start threshold can be increased to reduce unnecessary energy consumption.

[0102] Based on the first position information and in combination with the plurality of historical first air quality data of the first position information, the plurality of historical first air quality data is analyzed and processed to determine the improvement of indoor air quality after the fresh air handling unit starts under the corresponding air quality; wherein the same air quality data exists in the plurality of historical first air quality, and therefore the most suitable start threshold of the fresh air handling unit that can be used under the first air quality can be determined; for any combination of different first position information and different first air quality information, the corresponding start threshold of the fresh air handling unit that can be used is determined respectively, so as to obtain the first corresponding relationship; the first air quality information obtained currently is matched with the first corresponding relationship to determine the threshold with the highest matching degree, which is the start threshold corresponding to the current first position information and first air quality information.

[0103] For example, the air quality data usually includes but is not limited to the concentrations of pollutants such as PM2.5, PM10, SO2, NO2, and meteorological parameters such as temperature and humidity; since the air quality data includes multiple quality indicators, the plurality of historical first air quality data can be standardized to convert the data of different quality indicators into the same dimension or range, which is convenient for subsequent analysis; by statistical method or time series analysis, the trend of air quality at this position with time and season is understood, and the improvement of indoor air quality after the fresh air handling unit starts under different outdoor air quality conditions is determined, so as to establish the corresponding relationship between the first position information and the first air quality and the start threshold, that is, to obtain the first corresponding relationship; specifically, the first corresponding relationship includes: when the intelligent fresh air equipment A is set in the central area of city A, the start threshold of the corresponding fresh air handling unit is: CO2 concentration 800 ppm; when the intelligent fresh air equipment A is set in the suburb of city A, the start threshold of the corresponding fresh air handling unit is: CO2 concentration 1200 ppm.

[0104] S304: Obtain the second air quality information in the room.

[0105] S305: In the case that the second air quality information is greater than or equal to the starting threshold, it is detected whether there is a person in the room, in the case that there is a person in the room, the area where the person is located is determined, and the new air handling unit corresponding to the area is controlled to start.

[0106] It can be understood that the number of new air handling units in the new air equipment can be one or multiple; when the number of new air handling units in the new air equipment is multiple, different new air handling units can be set in different indoor areas to control the air quality of different indoor areas; in addition, each new air handling unit can be independently controlled, started and operated according to the air quality demand of the respective area, and each new air handling unit is pre-set with a control identifier, and the new air control module can accurately control the operation of the new air handling unit corresponding to the indoor area according to the control identifier of the different new air handling units.

[0107] For example, the intelligent new air equipment is a central new air equipment, and the central new air equipment can improve the air quality of different indoor areas (living room, bedroom, study room, etc.), and the new air handling units of different indoor areas can be started individually without affecting other areas.

[0108] Optionally, if there is no one in the room, it is judged whether the time from the last time the new air handling unit is started exceeds a preset time length, and if it exceeds, the new air handling unit is controlled to start.

[0109] The preset time length may be, for example, 15 days.

[0110] The second air quality information of the indoor environment is obtained in real time by the air quality detection sensor, and the new air control logic is determined, that is, the relationship between the second air quality information obtained at this time and the starting threshold is determined; in the case that the second air quality information is greater than or equal to the starting threshold, the human body detection sensor is used to detect whether there is a person in the indoor environment where the new air handling unit is currently located, if there is a person in the room, it indicates that the indoor area is being used, and the indoor personnel have actual demand for air quality, at this time, the indoor area where the indoor personnel are located is determined, and the new air handling unit corresponding to the indoor area is controlled to start to improve the indoor air quality.

[0111] If no one is detected in all indoor areas, it indicates that there is no one in the indoor environment where the intelligent new air equipment is currently located, at this time, it is judged whether the time node of the new air handling unit exceeds a preset time length from the last time the new air handling unit is started, if it exceeds, the new air handling unit is controlled to start to ensure that the indoor air quality will not deteriorate due to long time without people; if it does not exceed, the second air quality information is continuously detected.

[0112] For example, the current intelligent fresh air equipment includes three sets of fresh air units, and is installed in the living room, bedroom and study, respectively. The starting threshold of the current intelligent fresh air equipment can be 800 ppm. The second air quality information of the indoor is acquired in real time, that is, the CO2 concentration in the indoor is acquired in real time. If the current acquired CO2 concentration in the indoor is 900 ppm, that is, the current CO2 concentration is higher than the starting threshold. At this time, the human body detection sensor confirms whether there is a person in the overall indoor environment where the intelligent fresh air equipment is located, and determines the area where the person is in the case that there is a person in the indoor. If the detection result of the current human body detection sensor is that there is a person in the bedroom, at this time, the fresh air unit in the bedroom area is controlled to operate, and the fresh air unit starts to introduce fresh air and filter indoor pollutants to improve the indoor air quality.

[0113] S306: Determine the closing threshold of the fresh air unit based on the first air quality information and the first position information.

[0114] S307: Acquire the third air quality information of the indoor. In the case that the third air quality information is less than the closing threshold, control the fresh air unit to close.

[0115] The closing threshold is used to indicate the air quality threshold that the indoor air quality needs to reach before the fresh air unit stops operating.

[0116] It can be understood that the starting threshold and the closing threshold are respectively the air quality thresholds of whether the fresh air unit in the intelligent fresh air equipment starts or closes. In different geographical positions and air quality environments, the starting threshold and the closing threshold are different, and the fresh air control module pre-stores a plurality of closing thresholds. Therefore, the fresh air control module can automatically select and apply the corresponding closing threshold according to the first position information and the first air quality information acquired in real time.

[0117] The third air quality information and the second air quality information have a correlation relationship, and the third air quality information is the air quality information acquired in real time by the air quality detection sensor after the fresh air unit operates. The second air quality information is the air quality information acquired in real time by the air quality detection sensor before the fresh air unit is started, so as to determine whether the fresh air unit is started.

[0118] Based on the first air quality information and the first position information, a plurality of starting thresholds pre-stored in the intelligent fresh air equipment are matched to determine the threshold with the highest matching degree, and the threshold is used as the closing threshold of the fresh air unit in the intelligent fresh air equipment. After determining the closing threshold of the fresh air unit, the third air quality information of the indoor is acquired in real time by the indoor air quality detection sensor. In the case that the third air quality information is less than the closing threshold, the fresh air unit is controlled to close.

[0119] Optionally, based on the first position information, a second correspondence relationship between the outdoor air quality and a shutdown threshold of the fresh air handling unit is determined; and based on the first air quality information and the second correspondence relationship, the shutdown threshold is determined.

[0120] Based on the first position information and in combination with a plurality of historical first air quality data of the first position information, the plurality of historical first air quality data is analyzed and processed to determine the corresponding indoor air quality information when the fresh air handling unit is shut down under the corresponding air quality, and the most suitable shutdown threshold of the fresh air handling unit that can be adopted under different historical first air quality is determined therefrom; for any combination of different first position information and different first air quality information, the corresponding shutdown threshold of the fresh air handling unit that can be adopted is determined respectively, so as to obtain the second correspondence relationship.

[0121] For example, when the intelligent fresh air equipment A is arranged in the central area of city A, the shutdown threshold of the corresponding fresh air handling unit is 600 ppm of CO2 concentration; when the intelligent fresh air equipment A is arranged in the suburb of city A, the shutdown threshold of the corresponding fresh air handling unit is 650 ppm of CO2 concentration; the second air quality information of the indoor is obtained in real time, that is, the indoor CO2 concentration is obtained in real time, if the indoor CO2 concentration of the bedroom area currently obtained is 590 ppm, that is, the current CO2 concentration is lower than the shutdown threshold, at this time, the intelligent fresh air equipment is controlled to shut down the fresh air function.

[0122] The control method of the fresh air handling unit provided in the embodiment is to obtain the first air quality information of the outdoor and the first position information of the house; based on the first position information, a first correspondence relationship between the outdoor air quality and a startup threshold of the fresh air handling unit is determined; based on the first air quality information and the first correspondence relationship, the startup threshold is determined; the second air quality information of the indoor is obtained; in the case that the second air quality information is greater than or equal to the startup threshold, it is detected whether there is a person in the indoor, in the case that there is a person in the indoor, the area where the person is located is determined, and the corresponding fresh air handling unit of the area is controlled to start; based on the first air quality information and the first position information, a shutdown threshold of the fresh air handling unit is determined; the third air quality information of the indoor is obtained, and in the case that the third air quality information is less than the shutdown threshold, the fresh air handling unit is controlled to shut down. The method is suitable for different geographical environments and air quality conditions, and through dynamic adjustment of the startup and shutdown thresholds and the human sensing detection, the operation of the fresh air handling unit can be more accurately controlled, the indoor air quality is ensured to be always in a good state, a more flexible fresh air control strategy is provided, the overrunning or insufficient running of the fresh air handling unit is avoided, the energy utilization efficiency is optimized, the operation efficiency of the fresh air handling unit is improved, and the user experience, the comfort level and the health level of the user are improved.
