The air conditioner in the embodiment of the invention is mainly used for: responding to a preset mode starting instruction, and switching the air conditioner to a preset mode corresponding to the preset mode starting instruction;

Those skilled in the art can understand that the application environment shown in fig. 1 is only one application scenario of the present invention, and does not constitute a limitation on the application scenario of the present invention, and other application environments may also include more or less air conditioners 100 than those shown in fig. 1, for example, only one air conditioner 100 is shown in fig. 1, and it is understood that a specific application scenario of the air supply control method may also include one or more air conditioners 100, and is not limited herein; the air conditioner 100 may further include a memory.

Fig. 2 is a flow chart illustrating an air supply control method according to an embodiment of the present invention. As shown in fig. 2, the method comprises the following steps S110-S130.

And S110, responding to a preset mode starting instruction, and switching the air conditioner to a preset mode corresponding to the preset mode starting instruction.

In this embodiment, if the air conditioner A1 installed at the residence of the user a is taken as an example, if the user a can perform the man-machine interaction operation on the air conditioner A1 to start the preset mode (for example, the preset mode may be named as "care mode", "woman mode", etc.). After the operation is completed, the air conditioner A1 is switched to the preset mode and operated.

In an embodiment, the air conditioner further includes an infrared temperature sensor and a distance sensor, and before step S110, the method further includes:

acquiring a face image of an archiving user corresponding to a current archiving user through the camera;

carrying out face recognition on the face image of the archived user to obtain the face characteristics of the archived user and the gender information of the archived user;

detecting a man-machine distance between the current archiving user and the air conditioner through the distance sensor;

if the man-machine distance is smaller than a preset distance threshold value and the archived user gender information corresponds to a female user, acquiring a collected forehead temperature value corresponding to the current archived user through the infrared temperature sensor;

acquiring the current environment temperature, and determining a compensation temperature value based on the current environment temperature and the man-machine distance;

determining a basic body temperature value of a filed user according to the sum of the collected rated temperature value and the compensation temperature value;

and storing the archived user information consisting of the user ID corresponding to the facial features of the archived user, the gender information of the archived user, the basic body temperature value of the archived user and the body temperature acquisition date corresponding to the basic body temperature value of the archived user.

In this embodiment, in order to ensure that the air conditioner (e.g., the air conditioner A1 in the above example) can more accurately identify a specific user (e.g., the user a in the above example), when the air conditioner detects that the user is approaching the main body and operates the adjustment panel (including the display panel and the adjustment button, or the adjustment panel is changed to be the touch panel) on the main body, the camera may first collect the face image of the archiving user corresponding to the current archiving user (e.g., the user a).

Because the deep learning neural network model for face recognition is stored in the air conditioner, after the face image of the archived user is collected by the air conditioner, the face recognition (further comprising gender recognition) can be carried out on the face image of the archived user based on the deep learning neural network model, so that the face characteristics of the archived user and the gender information of the archived user can be obtained. At this time, the obtained face features of the archived user and the archived user gender information (if the user a is a woman, the archived user gender information corresponds to the woman) are both stored in a storage area (e.g., a memory) of the air conditioner. If the face image of the currently archived user, which is acquired this time, of the currently archived user is acquired for the first time, it indicates that the archived data has not been saved for the currently archived user in the air conditioner, at this time, an archiving area is newly created for the acquiring archived user, and the related user data (such as the face feature of the archived user, the gender information of the archived user, and the like) of the currently archived user is saved. If the face image of the current archiving user is not acquired for the first time, the current archiving user is the archived user, and then the data related to the current archiving user is acquired, and is continuously stored in the same storage area corresponding to the current archiving user in the air conditioner.

Since the air conditioner 100 is further provided with the distance sensor 102, as shown in fig. 3, the man-machine distance between the current archiving user and the air conditioner can be accurately detected by the distance sensor 102. The distance sensor is specifically arranged at the height position of 1.4-1.5 m of the air conditioner body, and can adopt an infrared slow reflection type distance measuring sensor or a laser distance measuring sensor to detect whether a person is in front of the air conditioner body 1.4-1.5 m and measure the man-machine distance.

Certainly, if the human-computer distance is too large, it is inconvenient to accurately acquire the forehead temperature of the user, so when it is determined that the human-computer distance is smaller than the preset distance threshold (for example, the distance threshold is set to 2m, and is not limited to 2m in specific implementation, or other distance values meeting the actual user requirements, such as 1m, 2.5m, and the like), and the gender information of the archived user corresponds to the female user, the acquired forehead temperature value corresponding to the current archived user is acquired through the infrared temperature sensor 103 arranged on the air conditioner 100, specifically please refer to fig. 3. The infrared temperature sensor 103 can be specifically an array infrared thermopile temperature sensor, and is arranged at a height position of 1.5-1.6 m (applicable to most of adult female heights, and capable of detecting the forehead temperature of a female user), the horizontal angle of the array infrared thermopile temperature sensor is more than 80 degrees, the vertical angle of the array infrared thermopile temperature sensor is more than 60 degrees, and a sensor array in the array infrared thermopile temperature sensor is more than 60 × 80 dot matrix, so that infrared temperature imaging with higher precision is realized.

When acquiring a collection forehead temperature value corresponding to a current file user through the infrared temperature sensor, the specific process is as follows:

1) Firstly, acquiring a head contour corresponding to the current file user through a camera, and identifying the position of the center of the forehead of the human body (namely the position of the forehead of the human body in a picture, and image coordinate recording or angle recording can be performed) on the basis of the head contour;

2) And then, the position of the center of the forehead of the human body is mapped to a temperature field obtained by an infrared temperature sensor, the temperature point of the position of the forehead of the human body is extracted, the temperature point is collected once every 20-100ms, the temperature point is continuously collected for a plurality of times (2-100 times) and the average value is calculated, and the average value is the collected forehead temperature value corresponding to the current file user. When the collected forehead temperature value corresponding to the current archiving user is not in the preset range (generally between 30 and 36 ℃), the collected forehead temperature value is invalid.

The acquired forehead temperature value corresponding to the current filed user cannot be directly used as the basic body temperature value of the user, and a certain compensation calculation is needed to obtain a more accurate basic body temperature value. Specifically, a current ambient temperature may be obtained by a temperature sensor further provided in the air conditioner, and a compensation temperature value may be determined based on the current ambient temperature and the man-machine distance. The air conditioner stores data of a plurality of human-computer distance-environment temperature-compensation temperature values in advance, namely the corresponding compensation temperature values can be inquired after the current environment temperature and the human-computer distance are known. And then summing the acquired rated temperature value and the compensation temperature value to obtain a basic body temperature value of the archiving user corresponding to the current archiving user.

When the user ID corresponding to the current archiving user is obtained (when the user ID is obtained based on the user face characteristics, the storage serial number in the user information archiving database in the air conditioner based on the user face characteristics can be used as the user ID), the archiving user gender information, the archiving user basic body temperature value and the body temperature acquisition date corresponding to the archiving user basic body temperature value are obtained, and the archiving user information corresponding to the current archiving user can be formed and stored.

In an embodiment, after saving the archived user information composed of the user ID corresponding to the archived user facial feature, the archived user gender information, and the archived user basic body temperature value, the method further comprises:

if the camera collects the face image corresponding to the current archived user, acquiring a time interval between the collection time of the face image and the acquisition time of the basic body temperature value of the archived user;

if the time interval is determined to be larger than or equal to a preset archiving time threshold value, and the acquisition time of the face image and the acquisition time of the basic body temperature value of the archiving user both belong to the same body temperature acquisition date, acquiring another basic body temperature value of the archiving user corresponding to the current archiving user, and updating the basic body temperature value of the archiving user by using the average value of the basic body temperature value of the archiving user and the basic body temperature value of the archiving user;

if the time interval is larger than or equal to the archiving time threshold value and the acquisition time of the face image and the acquisition time of the basic body temperature value of the archiving user do not belong to the same body temperature acquisition date, acquiring another archiving user basic body temperature value corresponding to the current archiving user and another body temperature acquisition date corresponding to the another archiving user basic body temperature value, and adding the another archiving user basic body temperature value and the another body temperature acquisition date into the archiving user information for storage.

In this embodiment, at least one archived user base body temperature value is acquired at a body temperature acquisition date corresponding to the archived user base body temperature value. If the user basic temperature value of the current archiving user is recorded according to at least the following two conditions in order to improve the accuracy of the basic temperature value of the archiving user corresponding to the current archiving user:

the first method is to determine that the time interval is greater than or equal to a preset archiving time threshold (for example, the archiving time threshold is set to 1h, although the specific implementation is not limited to 1h, and may also be other markets which can meet the actual use requirements, such as 2h, 4h, and the like), and when the acquisition time of the face image and the acquisition time of the basic body temperature value of the archiving user both belong to the same body temperature acquisition date, it means that the current archiving user approaches the air conditioner multiple times within one day and acquires the basic body temperature values of other archiving users, and when a new basic body temperature value of another archiving user is acquired and the time interval is greater than or equal to the time threshold, the basic body temperature value of the archiving user is updated by the average value of the basic body temperature value of the other archiving user and the basic body temperature value of the archiving user. If the archiving time threshold is set to be 1h, the air conditioner acquires the basic body temperature values of other archiving users of the current archiving user for multiple times on the same day, averages the basic body temperature values of the archiving users and the initially acquired basic body temperature values of the archiving users, and updates the basic body temperature values of the archiving users with the acquired average value.

And the second method is that when the time interval is determined to be greater than or equal to the archiving time threshold and the acquisition time of the face image and the acquisition time of the basic body temperature value of the archiving user do not belong to the same body temperature acquisition date, the acquisition time of the face image is represented as belonging to the next day relative to the acquisition time of the basic body temperature value of the archiving user, another archiving user basic body temperature value corresponding to the current archiving user and another body temperature acquisition date of the basic body temperature value of the another archiving user are acquired by referring to the acquisition mode of acquiring the basic body temperature value of the archiving user in the previous day, and the another archiving user basic body temperature value and the another body temperature acquisition date are added into the archiving user information for storage. For example, when the basic body temperature value of the archive user is collected for 28 consecutive days, the basic body temperature value of the archive user corresponding to at least 28 days is stored in the air conditioner for the current archive user. Besides, the basic body temperature values of the archived users stored for the same user on different dates in the air conditioner are arranged and stored according to the sequence of the collection dates.

In an embodiment, after saving the archived user information comprising the user ID corresponding to the facial feature of the archived user, the archived user gender information, the archived user basic body temperature value, and the body temperature acquisition date corresponding to the archived user basic body temperature value, the method further comprises:

acquiring basic body temperature values of the archived users, which are stored in the archived user information storage according to the date sequence and correspond to the number of the first preset body temperature values, so as to form a basic body temperature value sequence;

and determining physiological cycle information corresponding to the archived user information based on the basic body temperature value sequence and a preset sliding window strategy.

In this embodiment, after obtaining basic body temperature values of the archived user, which are stored in the archived user information by the same user (e.g., user a in the above example and user a is a female user) in order of date and time and correspond to the number of the first preset body temperature values (e.g., the number of the first preset body temperature values is set to 28), and forming a basic body temperature value sequence of the user (if the number of the first preset body temperature values is set to 28, the basic body temperature value sequence includes the basic body temperature values of the 28 archived users), physiological cycle information corresponding to the archived user information may be determined based on the basic body temperature value sequence and a preset sliding window policy. Moreover, determining the physiological cycle information of the user based on the sequence of the plurality of basic body temperature values results in more accurate results because more data is referenced than obtaining the physiological cycle information of the user based on several basic body temperature values.

In an embodiment, the determining physiological cycle information corresponding to the archived user information based on the basic body temperature value sequence and a preset sliding window strategy includes:

obtaining iteration times i; wherein the initial value of i is 1, the value range of i is [1, N1], and N1 is the number of the first preset body temperature values;

acquiring the base body temperature values of the 1 st-bit archived users to the N2 nd-bit archived users in the base body temperature value sequence, and summing to obtain a first temperature sum value; wherein N2 is the number of second preset body temperature values, and the number of the second preset body temperature values is one half of the number of the first preset body temperature values;

acquiring the archived user basic body temperature values from the (N2 + 1) th bit to the (N1) th bit in the basic body temperature value sequence, and summing to obtain a second temperature sum value; wherein,

acquiring and storing the ith ratio of the first temperature sum value to the second temperature sum value;

shifting the archived user basic temperature value with the 1 st bit ordered in the basic temperature value sequence to the last 1 bit of the basic temperature value sequence so as to update the basic temperature value sequence;

increasing i by 1 to update the value of i;

if the fact that i does not exceed N1 is determined, returning to the step of executing the obtaining iteration times i;

if i exceeds N1, acquiring the maximum value and the second largest value from the 1 st ratio to the N1 st ratio, determining the high-temperature period in the physiological cycle information according to the serial number value corresponding to the maximum value from the i th ratio to the N1 st ratio, and determining the low-temperature period in the physiological cycle information according to the serial number value corresponding to the second largest value from the i th ratio to the N1 st ratio.

In this embodiment, after obtaining the base body temperature value sequence corresponding to the currently archived user (user a in the above example), the high temperature period (i.e., ovulation period) and the low temperature period (i.e., menstruation period) in the physiological cycle information of the currently archived user can be determined in a sliding window manner. For example, if a basic body temperature value sequence includes 28 archived user basic body temperature values and is respectively recorded as T1-T28, the basic body temperature value sequence is most initially represented as [ T1, T2, T3, \8230;, T28], when the 1 st ratio is calculated in the 1 st round, the archived user basic body temperature values from the archived user basic body temperature value at the 1 st position to the archived user basic body temperature value at the 14 th position in the basic body temperature value sequence are obtained and summed to obtain a first temperature sum value, the user basic body temperature values from the archived user basic body temperature value at the 15 th position to the archived user basic body temperature value at the 28 th position in the basic body temperature value sequence are obtained and summed to obtain a second temperature sum value, and the result of dividing the first temperature sum value by the second temperature sum value is used as the 1 st ratio; then shifting T1 to the end of the sequence and shifting the other 27 archived user basal body temperature values forward by 1 bit to update the basal body temperature value sequence to [ T2, T3, \8230;, T28, T1] and calculate the 2 nd ratio therefrom; and by analogy, after 28 iterations, the 1 st ratio to the 28 th ratio can be obtained. And finally, determining the high-temperature period in the physiological cycle information by using the serial number value corresponding to the maximum value in the ratio from 1 st to 28 th, and determining the low-temperature period in the physiological cycle information by using the serial number value corresponding to the second largest value (namely the second largest ratio) in the ratio from 1 st to 28 th. And after the physiological cycle information corresponding to the current archiving user is determined, the physiological cycle information is stored in the air conditioner to be used as a reference parameter for controlling air supply according to the corresponding air supply strategy of the current archiving user.

And S120, acquiring a user face image through the camera in the preset mode, and performing face recognition on the user face image to obtain user information.

In this embodiment, as shown in fig. 3, since the air conditioner 100 is further provided with the camera 101 (i.e., the image collecting device, and the camera 101 is specifically arranged at a height position of 1.4m to 1.5m of the body of the air conditioner, and the horizontal angle of the camera is more than 80 °, and the vertical angle of the camera is more than 60 °), when a user approaches the air conditioner, the user face image can be collected by the camera first, and then the face recognition is performed on the user face image to obtain the user information. So that the air conditioner can determine which specific user is using the air conditioner based on the user information.

S130, if the user information is confirmed to be archived female user information, acquiring physiological cycle information corresponding to the user information, and correspondingly controlling the air supply of the air conditioner according to the physiological cycle information and a preset first air supply strategy.

In this embodiment, if the user face image corresponds to a user who is a archived user and corresponds to a female user, it indicates that the air conditioner can control the air supply of the air conditioner based on the first air supply strategy in the preset mode for the user. The air supply of the air conditioner is correspondingly controlled on the basis of the physiological cycle information and a preset first air supply strategy aiming at the archived female user information, the air supply is controlled by fully considering the current physical condition of the user, and the dynamic adjustment of the air supply mode on the basis of the physiological cycle of the female user is realized.

In one embodiment, as shown in fig. 4, step S130 includes:

s131, if the physiological cycle information is determined to correspond to the low-temperature period, acquiring a target area corresponding to the current position of the user, controlling the air conditioner to supply air at a preset adjusting temperature when the air conditioner is aligned to the target area, and controlling the air conditioner to supply air at a temperature set by the user when the air conditioner is not aligned to the target area;

and S132, if the physiological cycle information is determined to correspond to the high-temperature period, acquiring the temperature set by the user and controlling the air conditioner to supply air at the temperature set by the user.

In this embodiment, after the user information corresponding to the face image of the user and the physiological cycle information corresponding to the face image of the user are acquired, the low-temperature period (i.e., menstrual period), the high-temperature period (i.e., ovulation period), and the safe period of the user can be accurately known based on the physiological cycle information.

If the physiological cycle information is determined to correspond to the low-temperature period in the air conditioner, it is indicated that the area where the user is located corresponding to the face image of the user cannot send air-conditioning air with too low temperature, at this time, a target area corresponding to the current location of the user can be obtained through camera positioning, then the air conditioner is controlled to send air at a preset adjusting temperature when being aligned with the target area (if the air conditioner is used in a cooling mode at present, the preset adjusting temperature is 27-28 ℃, and if the air conditioner is used in a heating mode at present, the preset adjusting temperature is 22-24 ℃), and the air conditioner is controlled to send air at a user set temperature when being not aligned with the target area (if the air conditioner is used in a cooling mode of 26 ℃ originally set by the user, the air conditioner is controlled to send air when being aligned with the target area, the air conditioner is controlled to send air at the cooling mode of 26 ℃).

If the physiological cycle information is determined to correspond to the high temperature period, the female user needs constant air supply, so that the set temperature of the user is obtained, the air conditioner is controlled to supply air at the set temperature of the user, and if the user originally sets the air supply in the cooling mode of 26 ℃, the air conditioner is controlled to supply air at the cooling mode of 26 ℃ if the air conditioner is not aligned with the target area. Therefore, based on the accurate control of the air supply, the physiological cycle information of the user can be fully considered, and the air supply mode can be dynamically adjusted correspondingly.

In an embodiment, step S120 is followed by:

and if the user information is determined not to be the archived personnel information, correspondingly controlling the air supply of the air conditioner according to a preset second air supply strategy.

In this embodiment, if it is determined that the user information is not archived personal information, it indicates that the current user is not necessarily a female user, and the user does not have archived data in the air conditioner before, and at this time, the air supply of the air conditioner is directly controlled according to a second air supply strategy preset in the air conditioner. Specifically, if it is detected that the forehead temperature of the user is lower than 36.5 ℃ through the infrared temperature sensor, acquiring a target area corresponding to the current position of the user, controlling the air conditioner to supply air at a preset adjusting temperature when the air conditioner is aligned with the target area, and controlling the air conditioner to supply air at a temperature set by the user when the air conditioner is not aligned with the target area, which may specifically refer to the implementation manner of step S131; if it is detected that the forehead temperature of the user is higher than or equal to 36.5 ℃ by the infrared temperature sensor, acquiring a user-set temperature and controlling the air conditioner to supply air at the user-set temperature, which may be referred to in step S132.

In summary, in the embodiment, it can be recognized whether the current user is a female user, and when it is determined that the user is the archived female user information, the corresponding physiological cycle information is acquired, and the air conditioner is correspondingly controlled to supply air according to the physiological cycle information and the first air supply strategy, so that the air supply manner is dynamically adjusted in consideration of the physiological cycle of the female user.

The mode switching unit 110 is configured to switch the air conditioner to a preset mode corresponding to a preset mode starting instruction in response to the preset mode starting instruction.

In this embodiment, if the air conditioner A1 installed at the residence of the user a is taken as an example, if the user a can perform the man-machine interaction operation on the air conditioner A1 to start the preset mode (for example, the preset mode may be named as "care mode", "woman mode", etc.). When the operation is completed, the air conditioner A1 is switched to the preset mode and operated.

the archived user basic body temperature value acquisition unit is used for determining an archived user basic body temperature value according to the sum of the acquired rated temperature value and the compensation temperature value;

and the archived user information storage unit is used for storing archived user information consisting of the user ID corresponding to the facial features of the archived user, the archived user gender information, the archived user basic body temperature value and the body temperature acquisition date corresponding to the archived user basic body temperature value.

Because the deep learning neural network model for face recognition is stored in the air conditioner, after the face image of the archived user is collected by the air conditioner, the face recognition (further comprising gender recognition) can be carried out on the face image of the archived user based on the deep learning neural network model, so that the face characteristics of the archived user and the gender information of the archived user can be obtained. At this time, the obtained face features of the archived user and the archived user gender information (if the user a is a woman, the archived user gender information corresponds to the woman) are both saved in a storage area (e.g., a memory) of the air conditioner. If the face image of the currently archived user, which is acquired this time, of the currently archived user is acquired for the first time, it indicates that the archived data has not been saved for the currently archived user in the air conditioner, at this time, an archiving area is newly created for the acquiring archived user, and the related user data (such as the face feature of the archived user, the gender information of the archived user, and the like) of the currently archived user is saved. If the face image of the current archived user is not acquired for the first time, the current archived user is the archived user, then the data related to the current archived user is acquired, and the data is continuously stored in the same storage area corresponding to the current archived user in the air conditioner.

Certainly, if the human-computer distance is too large, it is inconvenient to accurately acquire the forehead temperature of the user, so when it is determined that the human-computer distance is smaller than the preset distance threshold (for example, the distance threshold is set to 2m, and is not limited to 2m in specific implementation, or other distance values meeting the actual user requirements, such as 1m, 2.5m, and the like), and the gender information of the archived user corresponds to the female user, the acquired forehead temperature value corresponding to the current archived user is acquired through the infrared temperature sensor 103 arranged on the air conditioner 100, specifically please refer to fig. 3. Wherein, infrared temperature sensor 103 specifically can adopt array infrared thermopile temperature sensor, set up in the high position of air conditioner fuselage 1.5m ~ 1.6m (applicable in most adult women height, can detect women user's forehead temperature), array infrared thermopile temperature sensor's horizontal angle is more than 80 and vertical angle is more than 60, the sensor array among the array infrared thermopile temperature sensor is more than 60 x 80 dot matrix to realize the infrared temperature formation of image of higher accuracy.

1) Firstly, acquiring a head contour corresponding to the current file user through a camera, and identifying the position of the center of the human forehead (namely the position of the human forehead in a picture, and image coordinate recording or angle recording can be performed) based on the head contour;

The acquired collected forehead temperature value corresponding to the current filed user cannot be directly used as the basic body temperature value of the user, and a certain compensation calculation is needed to obtain a more accurate basic body temperature value. Specifically, a current ambient temperature may be obtained by a temperature sensor further provided in the air conditioner, and a compensation temperature value may be determined based on the current ambient temperature and the man-machine distance. The air conditioner is pre-stored with data of a plurality of human-computer distance-environment temperature-compensation temperature values, namely, the corresponding compensation temperature values can be inquired after the current environment temperature and the human-computer distance are known. And then summing the acquired rated temperature value and the compensation temperature value to obtain a basic body temperature value of the archiving user corresponding to the current archiving user.

In an embodiment, the air conditioner 100 further includes:

the time interval determining unit is used for acquiring the time interval between the acquisition time of the face image and the acquisition time of the basic body temperature value of the archived user if the face image corresponding to the archived user is acquired by the camera;

an average temperature value obtaining and storing unit, configured to obtain another basic temperature value of the archive user corresponding to the current archive user if it is determined that the time interval is greater than or equal to a preset archive time threshold and the acquisition time of the face image and the acquisition time of the basic temperature value of the archive user both belong to the same body temperature acquisition date, and update the basic temperature value of the archive user with an average value of the basic temperature value of the other archive user and the basic temperature value of the archive user;

and the multi-temperature value acquisition and storage unit is used for acquiring another basic body temperature value of the archiving user corresponding to the current archiving user and another body temperature acquisition date corresponding to the basic body temperature value of the archiving user if the time interval is determined to be greater than or equal to the archiving time threshold and the acquisition time of the face image and the acquisition time of the basic body temperature value of the archiving user do not belong to the same body temperature acquisition date, and adding the basic body temperature value of the archiving user and the another body temperature acquisition date to the archiving user information for storage.

In this embodiment, at least one archived user base body temperature value was previously acquired on a body temperature acquisition date corresponding to the archived user base body temperature value. If the basic temperature value of the current filing user is more accurate, the basic temperature value of the current filing user can be recorded according to at least the following two situations:

And the second method is that when the time interval is determined to be greater than or equal to the archiving time threshold value and the acquisition time of the face image and the acquisition time of the basic body temperature value of the archiving user do not belong to the same body temperature acquisition date, the acquisition time of the face image is determined to belong to the next day relative to the acquisition time of the basic body temperature value of the archiving user, another archiving user basic body temperature value corresponding to the current archiving user and another body temperature acquisition date corresponding to the another archiving user basic body temperature value are acquired by referring to the acquisition mode of acquiring the basic body temperature value of the archiving user in the previous day, and the another archiving user basic body temperature value and the another body temperature acquisition date are added into the archiving user information for storage. For example, when the basic body temperature value of the archive user is collected for 28 consecutive days, the basic body temperature value of the archive user corresponding to at least 28 days is stored in the air conditioner. Besides, the basic body temperature values of the archived users stored for the same user on different dates in the air conditioner are arranged and stored according to the sequence of the collection dates.

In an embodiment, the air conditioner 100 further includes:

a basic body temperature value sequence acquiring unit, configured to acquire basic body temperature values of the archived users, which are stored in the archived user information storage according to the order of date and correspond to the number of the first preset body temperature values, so as to form a basic body temperature value sequence;

and the physiological cycle information determining unit is used for determining the physiological cycle information corresponding to the archived user information based on the basic body temperature value sequence and a preset sliding window strategy.

In an embodiment, the physiological cycle information determining unit is specifically configured to:

increasing i by 1 to update the value of i;

In this embodiment, after obtaining the basic temperature value sequence corresponding to the current archiving user (user a in the above example), the high temperature period (i.e. ovulation period) and the low temperature period (i.e. menstruation period) in the physiological cycle information of the current archiving user can be determined in a sliding window manner. For example, if a basic body temperature value sequence includes 28 archived user basic body temperature values and is respectively recorded as T1-T28, the basic body temperature value sequence is most initially represented as [ T1, T2, T3, \8230;, T28], when the 1 st ratio is calculated in the 1 st round, the archived user basic body temperature values from the archived user basic body temperature value at the 1 st position to the archived user basic body temperature value at the 14 th position in the basic body temperature value sequence are obtained and summed to obtain a first temperature sum value, the user basic body temperature values from the archived user basic body temperature value at the 15 th position to the archived user basic body temperature value at the 28 th position in the basic body temperature value sequence are obtained and summed to obtain a second temperature sum value, and the result of dividing the first temperature sum value by the second temperature sum value is used as the 1 st ratio; then shifting T1 to the last bit of the sequence and shifting the other 27 archived user basal body temperature values forward by 1 bit to update the basal body temperature value sequence to [ T2, T3, \8230;, T28, T1] and calculate the 2 nd ratio; and by analogy, after 28 iterations, the 1 st to 28 th ratios can be obtained. And finally, determining the high-temperature period in the physiological cycle information by using the serial number value corresponding to the maximum value in the ratio from 1 st to 28 th, and determining the low-temperature period in the physiological cycle information by using the serial number value corresponding to the second largest value (namely, the second largest ratio) in the ratio from 1 st to 28 th. And after determining the physiological cycle information corresponding to the current archived user, storing the physiological cycle information in the air conditioner as a reference parameter for controlling air supply according to the corresponding air supply strategy of the current archived user.

And the user information identification unit 120 is configured to acquire a user face image through the camera in the preset mode, and perform face identification on the user face image to obtain user information.

And the first air supply control unit 130 is configured to, if it is determined that the user information is archived female user information, acquire physiological cycle information corresponding to the user information, and correspondingly control air supply of the air conditioner according to the physiological cycle information and a preset first air supply strategy.

In an embodiment, the first blowing control unit 130 is specifically configured to:

if the physiological cycle information is determined to correspond to the low-temperature period, acquiring a target area corresponding to the current position of the user, controlling the air conditioner to supply air at a preset adjusting temperature when the air conditioner is aligned to the target area, and controlling the air conditioner to supply air at a temperature set by the user when the air conditioner is not aligned to the target area;

and if the physiological cycle information is determined to correspond to the high-temperature period, acquiring the set temperature of the user and controlling the air conditioner to supply air at the set temperature of the user.

Then, if it is determined that the physiological cycle information corresponds to a low-temperature period in the air conditioner, it indicates that the area where the user face image corresponds to the user currently cannot send air-conditioning air with too low temperature, at this time, a target area corresponding to the user currently located position can be obtained through camera positioning, then the air conditioner is controlled to send air at a preset adjusting temperature when being aligned with the target area (the preset adjusting temperature is 27-28 ℃ if the air conditioner is currently used in a cooling mode, and the preset adjusting temperature is 22-24 ℃ if the air conditioner is currently used in a heating mode), and the air conditioner is controlled to send air at a user-set temperature when being misaligned with the target area (the air conditioner is controlled to send air at 26 ℃ when being misaligned with the target area if the air conditioner is originally set at 26 ℃ in a cooling mode).

If the physiological cycle information is determined to correspond to the high temperature period, the female user needs constant air supply, so that the set temperature of the user is obtained, the air conditioner is controlled to supply air at the set temperature of the user, and if the user originally sets the air supply in the cooling mode of 26 ℃, the air conditioner is controlled to supply air at the cooling mode of 26 ℃ if the air conditioner is not aligned with the target area. Therefore, based on the accurate control of the air supply, the physiological cycle information of the user can be fully considered, and the air supply mode can be correspondingly and dynamically adjusted.

In an embodiment, the air conditioner 100 further includes:

and the second air supply control unit is used for correspondingly controlling the air supply of the air conditioner according to a preset second air supply strategy if the user information is determined not to be the archived personnel information.

In this embodiment, if it is determined that the user information is not archived person information, it indicates that the current user is not necessarily a female user, and the user does not have archived data in the air conditioner before, and at this time, the air conditioner is directly controlled to supply air according to a second air supply policy preset in the air conditioner. Specifically, if it is detected that the forehead temperature of the user is lower than 36.5 ℃ through the infrared temperature sensor, acquiring a target area corresponding to the current position of the user, controlling the air conditioner to supply air at a preset adjusting temperature when the air conditioner is aligned with the target area, and controlling the air conditioner to supply air at a temperature set by the user when the air conditioner is not aligned with the target area, which may specifically refer to the implementation manner of step S131; if the infrared temperature sensor detects that the forehead temperature of the user is higher than or equal to 36.5 ℃, acquiring the set temperature of the user and controlling the air conditioner to supply air at the set temperature of the user, which may be referred to in step S132.

In summary, in this embodiment, it can be identified whether the current user is a female user, and when it is determined that the current user is female user information that has been filed, the corresponding physiological cycle information is obtained, and the air conditioner is controlled to supply air according to the physiological cycle information and the first air supply strategy, so that the air supply manner is dynamically adjusted in consideration of the physiological cycle of the female user.
