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

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 disposed at the residence of the user a is taken as an example, if the user a can perform man-machine interaction operation on the air conditioner A1 to turn on the preset mode (for example, the preset mode may be named as "care mode", "female mode", etc.). When 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 the step S110 further includes:

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

performing face recognition on the face image of the archiving user to obtain the face characteristics of the archiving user and the gender information of the archiving user;

detecting the 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 and the archived user gender information corresponds to a female user, acquiring an acquisition forehead temperature value corresponding to the current archived user through the infrared temperature sensor;

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

determining an archived user base body temperature value according to the sum of the acquired forehead temperature value and the compensated temperature value;

and storing the 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.

In this embodiment, in order to ensure that the air conditioner (such as the air conditioner A1 in the above example) can more accurately identify the specific user (such as the user a in the above example), when the air conditioner detects that the user approaches the body and operates the adjusting panel (including the display panel and the adjusting key, or changes the adjusting panel to be a touch panel) on the body, the camera is used to collect the face image of the archiving user corresponding to the current archiving user (such as the user a).

Because the deep learning neural network model for face recognition is stored in the air conditioner, after the air conditioner collects the face images of the archiving user, face recognition (further comprising sex recognition) can be carried out on the face images of the archiving user based on the deep learning neural network model, so that the face characteristics of the archiving user and the sex information of the archiving user are obtained. At this time, the obtained facial features of the archiving user and the gender information of the archiving user (if the user a is female, the gender information of the archiving user corresponds to female) are both stored in a storage area (such as a memory) of the air conditioner. If the face image of the current archiving user is acquired for the first time, the fact that the archiving data of the current archiving user is not saved in the air conditioner before is indicated, at the moment, an archiving area is newly built for the current archiving user, and relevant user data (such as facial features of the archiving user, gender information of the archiving user and the like) of the current archiving user are 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 the data are 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 human-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 m-1.5 m of the air conditioner body, and can be an infrared slow reflection type distance measuring sensor or a laser distance measuring sensor, so as to be used for detecting whether a person is right in front of the air conditioner body 1.4 m-1.5 m and measuring the distance between the person and the machine.

Of course, if the man-machine distance is too large, it is inconvenient to accurately collect the forehead temperature of the user, so when it is determined that the man-machine distance is smaller than the preset distance threshold (for example, the distance threshold is set to 2m, the implementation is not limited to 2m, other distance values meeting the actual user needs, such as 1m, 2.5m, etc.), and the archived user gender information corresponds to the female user, the collected forehead temperature value corresponding to the current archived user is obtained through the infrared temperature sensor 103 set on the air conditioner 100, please refer to fig. 3 specifically. The infrared temperature sensor 103 may be an array infrared thermopile temperature sensor, which is disposed at a height position of 1.5 m-1.6 m of the air conditioner body (applicable to most adult female heights, and can detect forehead temperature of female users), wherein a horizontal angle of the array infrared thermopile temperature sensor is above 80 ° and a vertical angle of the array infrared thermopile temperature sensor is above 60 ° and a sensor array in the array infrared thermopile temperature sensor is above 60×80 dot matrix, so as to realize infrared temperature imaging with higher precision.

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

1) Firstly, acquiring a head outline corresponding to the current archiving user through a camera, and identifying the position of the center of the forehead of the human body based on the head outline (namely, the position of the forehead of the human body in a picture can be recorded by image coordinates or angles);

2) Then, the position of the forehead of the human body is reflected to a temperature field acquired by an infrared temperature sensor, the temperature point of the forehead of the human body is extracted, the temperature point is acquired once every 20-100ms, the temperature point is continuously acquired for a plurality of times (which can be 2-100 times), and an average value is calculated, wherein the average value is an acquired forehead temperature value corresponding to a current archiving user. When the collected forehead temperature value corresponding to the current archiving user is not in the preset range (generally 30-36 ℃), the collected forehead temperature value is invalid.

The acquired collected forehead temperature value corresponding to the current archiving user cannot be directly used as the user base body temperature value, and a certain compensation calculation is needed to obtain a more accurate base body temperature value. Specifically, a temperature sensor further arranged in the air conditioner can firstly acquire the current environment temperature, and a compensation temperature value is determined based on the current environment temperature and the man-machine distance. The data of a plurality of man-machine spacing-environment temperature-compensation temperature values are prestored in the air conditioner, namely, the corresponding compensation temperature values can be inquired after the current environment temperature and the man-machine spacing are known. And then, summing the acquired forehead temperature value and the compensation temperature value to obtain an archiving user basic body temperature value 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 feature, the storage serial number in the user information archiving database in the air conditioner can be used as the user ID based on the user face feature), the archiving user sex information, the archiving user basic body temperature value and the body temperature acquisition date corresponding to the archiving user basic body temperature value can be formed into the archiving user information corresponding to the current archiving user and stored.

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

If the camera acquires the face image corresponding to the current archiving user, acquiring a time interval between acquisition time of the face image and acquisition time of the archiving user basic body temperature value;

If the time interval is 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 archiving user basic body temperature value all belong to the same body temperature acquisition date, acquiring another archiving user basic body temperature value corresponding to the current archiving user, and updating the archiving user basic body temperature value by using the average value of the another archiving user basic body temperature value and the archiving user basic body temperature value;

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 archiving user basic body temperature value 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 of 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 was previously obtained on a body temperature acquisition date corresponding to the archived user base body temperature value. If, in order to improve the accuracy of the user base body temperature value corresponding to the current archive user, the user base body temperature value of the current archive user can be recorded in at least two cases:

The first method is that when it is determined 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, of course, the specific implementation is not limited to 1h, other markets that can meet the actual use requirement can be also used, such as 2h, 4h, etc.), and the acquisition time of the face image and the acquisition time of the archiving user basic body temperature value all belong to the same body temperature acquisition date, the current archiving user is indicated to approach an air conditioner for many times in a day and acquire other multiple archiving user basic body temperature values of the current archiving user, and each time a new basic body temperature value of another archiving user is acquired and the time interval is greater than or equal to the archiving time threshold, the archiving user basic body temperature value is updated by the average value of the basic body temperature value of the other archiving user and the archiving user basic body temperature value. If the archiving time threshold is set to 1h, the air conditioner acquires a plurality of other archiving user basic body temperature values of the current archiving user for a plurality of times on the same day, averages the archiving user basic body temperature values and the archiving user basic body temperature values which are acquired initially, and updates the archiving user basic body temperature values by the obtained average value.

And secondly, when 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 archiving user basic body temperature value do not belong to the same body temperature acquisition date, the acquisition time of the face image is represented to belong to the next day relative to the acquisition time of the archiving user basic body temperature value, another archiving user basic body temperature value corresponding to the current archiving user is acquired by referring to the acquisition mode of the archiving user basic body temperature value acquired in the previous day, and another body temperature acquisition date of the archiving user basic body temperature value is acquired, and the another archiving user basic body temperature value and the another body temperature acquisition date are added to the archiving user information for storage. For example, when the archived user base body temperature values are collected on 28 consecutive days, then at least 28 days of the respective archived user base body temperature values are stored in the air conditioner for the current archived user. In addition, the base body temperature values of the archive users stored for the same user on different dates are arranged and stored according to the sequence of the acquisition dates in the air conditioner.

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

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

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

In this embodiment, when the same user (user a in the above example and when the user a is a female user) is obtained, the base body temperature values of the archive user corresponding to the first preset body temperature value number (for example, the first preset body temperature value number is set to 28) are stored in the archive user information according to the chronological order, and a base body temperature value sequence of the user is formed (if the first preset body temperature value number is set to 28, the base body temperature value sequence includes 28 base body temperature values of the archive user), and then physiological cycle information corresponding to the archive user information can be determined based on the base body temperature value sequence and a preset sliding window policy. In addition, compared with the process of acquiring the physiological cycle information of the user based on a plurality of basic body temperature values, the physiological cycle information of the user is determined based on a sequence consisting of a plurality of basic body temperature values, and the obtained result is more accurate because the obtained result refers to more data.

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

acquiring 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 archiving user from the 1 st position to the N2 nd position in the sequence of the base body temperature values, and summing to obtain a first temperature sum value; wherein N2 is the number of second preset body temperature values, and the number of second preset body temperature values is one half of the number of first preset body temperature values;

Acquiring the basis body temperature values of the user, which are ordered from the N2+1st to the N1 st, from the basis body temperature value sequence, and summing the basis body temperature values to obtain a second temperature sum value; wherein,

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

Shifting the 1 st ordered archive user base body temperature value in the base body temperature value sequence to the last 1 st of the base body temperature value sequence to update the base body temperature value sequence;

Adding 1 to the i to update the value of i;

If the i is determined not to exceed N1, returning to the step of acquiring the iteration number i;

If it is determined that i exceeds N1, the maximum value and the next largest value in the 1 st ratio to the N1 st ratio are obtained, the high-temperature period in the physiological cycle information is determined according to the serial number value corresponding to the maximum value in the i st ratio to the N1 st ratio, and the low-temperature period in the physiological cycle information is determined according to the serial number value corresponding to the next largest value in the i st ratio to the N1 st ratio.

In this embodiment, after the base body temperature value sequence corresponding to the current archiving user (such as user a in the above example) is obtained, a sliding window manner is used to determine the high temperature period (i.e. ovulatory period) and the low temperature period (i.e. menstrual period) in the physiological cycle information in the current archiving user. For example, 28 archived user basic body temperature values are included in a basic body temperature value sequence and are respectively recorded as T1-T28, the most initial representation of the basic body temperature value sequence is [ T1, T2, T3, … …, T28], when the 1 st round of calculating the 1 st ratio is performed, the first temperature sum value is obtained by obtaining the archived user basic body temperature values from the 1 st to the 14 th in the sequence of the basic body temperature values, the second temperature sum value is obtained by obtaining the archived user basic body temperature values from the 15 th to the 28 th in the sequence of the basic body temperature values and summing, and the result of dividing the first temperature sum value by the second temperature sum value is taken as the 1 st ratio; then shifting T1 to the end of the sequence and shifting the base body temperature values of the other 27 archiving users forward by 1 bit to update the base body temperature value sequence to be [ T2, T3, … …, T28, T1] and calculating the 2 nd ratio according to the base body temperature value sequence; and by analogy, the 1 st ratio to the 28 th ratio can be obtained after the iteration is performed for 28 times. And finally, determining a high-temperature period in the physiological cycle information by using a serial number value corresponding to the maximum value in the 1 st ratio to the 28 th ratio, and determining a low-temperature period in the physiological cycle information by using a serial number value corresponding to the next-largest value (namely, the second largest ratio) in the 1 st ratio to the 28 th ratio. When 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 aiming at the current archiving user.

And S120, acquiring a user face image through the camera under the preset mode, and carrying out face recognition on the user face image to acquire user information.

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

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

In this embodiment, if the user corresponding to the face image of the user is an archived user and corresponds to a female user, it indicates that the air conditioner can control the air conditioner to supply air to the user based on the first air supply policy in the preset mode. Because the air conditioner is correspondingly controlled to supply air according to the archived female user information based on the physiological cycle information and a preset first air supply strategy, the air supply is controlled by fully considering the current physical condition of the user, and the dynamic air supply mode adjustment based on 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 a low-temperature period, a target area corresponding to the current position of the user is obtained, the air conditioner is controlled to supply air at a preset adjusting temperature when aiming at the target area, and the air conditioner is controlled to supply air at a user set temperature when not aiming at the target area;

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

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 obtained, 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.

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

If the physiological cycle information is determined to correspond to the high-temperature period, the female user is required to supply air constantly, so that the user set temperature is obtained, the air conditioner is controlled to supply air at the user set temperature, if the user originally sets the cooling mode to supply air at 26 ℃, the air conditioner is controlled to supply air at 26 ℃ in the cooling mode when the target area is not aligned. 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, step S120 further includes:

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

In this embodiment, if it is determined that the user information is not the archived personnel information, it indicates that the current user is not necessarily a female user, and the user has no 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 the infrared temperature sensor detects that the user forehead temperature is lower than 36.5 ℃, a target area corresponding to the current position of the user is obtained, the air conditioner is controlled to supply air at a preset adjusting temperature when the air conditioner is aligned to the target area, and the air conditioner is controlled to supply air at a user setting temperature when the air conditioner is not aligned to the target area, and the implementation of step S131 can be referred to specifically; if the infrared temperature sensor detects that the user forehead temperature is higher than or equal to 36.5 ℃, the user set temperature is obtained and the air conditioner is controlled to supply air at the user set temperature, and the embodiment of step S132 can be referred to specifically.

In summary, the embodiment not only can identify whether the current user is a female user, but also obtains the corresponding physiological cycle information when determining that the user is the archived female user information, and correspondingly controls the air conditioner to supply air according to the physiological cycle information and the first air supply strategy, thereby realizing the dynamic adjustment of the air supply mode by fully considering the physiological cycle of the female user.
