Technical solution provided by the embodiments of the present application is applied to air-conditioning, and carrying out one to air-conditioning first introduces, below
Each unit in air-conditioning will be described in more details in second aspect.In the embodiment of the present application, air-conditioning setting exists
In first space, and any position being arranged in the first space.First space is, for example, parlor, bedroom, office etc., this Shen
Please this is not limited.
Air-conditioning includes stepper motor, and the infrared array that is arranged on stepper motor and can be driven to rotate.Stepping
The control unit of motor and air-conditioning connects, and control unit is rotated according to the requirement control stepper motor of processing unit, and then is controlled
Infrared array rotates.Infrared array is connect with processing unit, and the information that scanning obtains is transferred to processing unit.Specific real
During now, infrared array can be 4 × 16 infrared array, 24 × 32 infrared array or 1 × 32 infrared array
It can be according to actually selecting Deng, the application those of ordinary skill in the art, the application is not particularly limited.Later
It is middle the recognition methods in the embodiment of the present application to be illustrated by taking 4 × 16 infrared array as an example.
In addition, during specific implementation, control unit and processing unit can be the same unit in air-conditioning, such as locate
Manage device, microcontroller etc., or independent two units.
In the embodiment of the present application first aspect, recognition methods provided by the present application will be introduced.As shown in Figure 1, identification side
Method includes the following steps：
S101：Controlling the stepper motor in the air-conditioning drives the infrared array in the air-conditioning to scan at least one week
Phase, to obtain a frame environment temperature infrared image after the completion of to first spacescan by the infrared array.
S102：Human body pixel point is determined from the environment temperature infrared image.
S103：Determine that first space is that there are spaces there is currently the user of user based on the human body pixel point.
Specifically, since the angle of visibility of infrared array is limited, such as 15 degree, 20 degree etc., therefore obtain the first sky for scanning
Between environment temperature infrared image, infrared array needs to scan at least one period.Wherein, the angle of visibility characterization of infrared array is red
When outer array is static, lateral maximum angle that single pass can scan.As an example it is assumed that angle of visibility is 16 degree, scanning
The initial position in the first space and final position angle are 48 degree, then need 3 periods of scanning that can just scan through the first space.
During specific implementation, infrared array obtains the amount of cycles specifically scanned required for a frame environment temperature infrared image, this Shen
Please those of ordinary skill in the art according to being actually configured, the application is not particularly limited.
Within each period, stepper motor can drive infrared array rotary scanning n times, and then obtain n group temperature datas.Tool
For body, in ith scanning, stepper motor drives infrared array to rotate Xi degree.Wherein, i is 1 to any integer between n,
N is the positive integer more than 1, and Xi is positive number.In each period, stepper motor drives the angle value that infrared array is rotated, with
The angle value of the angle of visibility of infrared array is identical.That is, in the 1st scanning of current period, infrared array rotates X1 degree, obtains
1st group of temperature data；In 2nd scanning, infrared array rotates X2 degree, obtains the 2nd group of temperature data；…；In n-th scanning,
Infrared array rotates Xn degree, obtains n-th group temperature data.Wherein, X1, X2 ..., Xn are not all the same positive number, and X1+X2
+ ...+Xn=C, C are the angle value of angle of visibility.
As an example it is assumed that the angle of visibility of infrared array is 16 °, n 4, X1=1 °, X2=1 °, X3=1 °, X4=13 °.
So scanning obtains the 1st group of temperature data after infrared array will rotate 1 ° from the initial position of current period.Then 1 ° is rotated,
Obtain the 2nd group of temperature data.Then it is rotated further by 1 ° of scanning and obtains the 3rd group of temperature data.It finally rotates 13 ° of scannings and obtains the 4th group
Temperature data.This is arrived, current period terminates.
After the completion of scanning, multigroup temperature data build environment temperature in multiple periods that processing unit is obtained according to scanning
Infrared image.The pixel value of each pixel in environment temperature infrared image characterizes the temperature of the corresponding zonule in the first space
Degree.
Specifically, the temperature data that each intermittent scanning of infrared array is obtained is recorded with 4 × 16 matrix.At this
Apply in embodiment, if there is at least two groups temperature data to there is overlapping, the temperature data of lap to take at least two groups temperature
The average value of the corresponding part of data.As illustrated in fig. 2, it is assumed that obtain jth group temperature data and+1 group temperature data of jth when
It waits, infrared array scans the shadow region A in Fig. 2.So jth group temperature data and+1 group temperature data of jth be just
Overlapping.In build environment temperature infrared image ,+1 group temperature data overlapping region average value of jth group temperature data and jth is taken
Temperature data as region A.Such as overlapped data is specially the 3-4 column datas of jth group temperature data ,+1 temperature number of jth
According to 1-2 column datas, then take temperature data of the average value of above-mentioned two column data as region A.Wherein, jth group temperature number
According to and+1 group temperature data of jth be the 1st group of temperature data of period 1 to the end between the last 1 group of temperature data of a cycle
Arbitrary two groups of temperature datas continuously successively obtained, and jth group temperature data is obtained prior to+1 group temperature data of jth.
According to the corresponding cycle sequences of each matrix are obtained, using multiple matrix-expands as a big matrix, to obtain
The temperature data that acquisition obtains at least one period., can be in such a way that row extend during specific implementation, it can also
Big matrix is obtained in the way of arranging and extending.
As an example it is assumed that at least one period is specially 3 periods, and the temperature data that each period obtains is 4
× 16 matrix.If in the way of arranging and extending, then the temperature data of a cycle is arranged as the 1st row the 1st to the 4th row the
The data of 16 row, the temperature data of second period arrange the data arranged to the 4th row the 32nd, third period as the 1st row the 17th
Temperature data the data arranged to the 4th row the 48th are arranged as the 33rd row the 1st.To which the temperature data in three periods is just extended to
One 4 × 48 big matrix.If in such a way that row extends, then the temperature data of a cycle is arranged as the 1st row the 1st
The data arranged to the 4th row the 16th, the temperature data of second period arrange the data arranged to eighth row the 16th as the 5th row the 1st, the
The temperature data in three periods arranges the data arranged to the 12nd row the 16th as the 9th row the 1st.To the temperature data in three periods
Just it has been extended to one 12 × 16 big matrix.
Finally, processing unit generates a frame environment temperature infrared image according to the temperature data in big matrix.Environment temperature
The pixel value of each pixel in infrared image, value identical with position in big matrix value are corresponding.Such as environment temperature is infrared
The pixel value of the pixel of the 1st row the 3rd row in image, it is corresponding with the value that the 1st row the 3rd in big matrix value arranges.
After obtaining environment temperature infrared image, air-conditioning further analyzes environment temperature infrared image, and then identifies
Go out or determine human body.S102：Human body pixel point is determined from the environment temperature infrared image.
Specifically, in the embodiment of the present application, to determine human body pixel point, a human body benchmark can be pre-set
Value.Wherein human body a reference value can be default setting, such as 35 degree or 36 degree etc..Environment temperature infrared image is carried out global
Search, will be above the pixel of human body a reference value as human body pixel point.
Optionally, human body pixel point can be identified according to more complicated algorithm.Specifically, first to environment temperature
Infrared image carries out Fourier transformation, using the three times and three times filter value of the above harmonic wave as Filling power.Then use CCL (competing
Strive and cooperative learning, Competitive and Cooperative Learning) algorithm, according to 8 fields to the infrared figure of environment
As scanning for.Finally using second harmonic filter value as human body pixel point.
If from environment temperature infrared image, it is unidentified go out human body pixel point, then show not deposit currently in the first space
In user, then in order to economize on resources, operating mode can be automatically adjusted to low-power consumption mode by air-conditioning from high power consumption mode, or
Person's automatic shutdown etc..
And if air-conditioning has identified human body pixel point from environment temperature infrared image, shows to exist in the first space and use
Family, then executing S103：Determine that first space is that there is currently the users of user there is sky based on the human body pixel point
Between.
Further, determine the first space be user there are space after, air-conditioning can execute automatic startup, Automatic-cooling,
Wind direction is adjusted to operations such as user's directions.The those of ordinary skill in herein described field can carry out according to actual needs
Setting, the application are not particularly limited.
Since children are in sleep procedure, son may be kicked quilt, and then sick.Air-conditioning in the embodiment of the present application can be into
One step is for judging whether children kick quilt son.Therefore, optionally, after S103, can also include：
From the human body pixel point, initial exposed pixel is determined；
The human body pixel point is corresponding with the user, and the initial exposed pixel and the user are unlapped at least
Corresponding to a part.
Specifically, during children sleeping, some parts of body are capped, such as belly, leg etc., and are had
A little is partly uncovered, such as head.In the embodiment of the present application, to judge whether children kick quilt son, need to realize from human body
Exposed pixel is determined in pixel.Wherein, human body pixel point, as shown in " S " in Fig. 3 and " * ", with user, i.e. children couple
It answers, corresponding to exposed pixel and unlapped at least one portion, the children head as represented by Fig. 3 " * ".
Specifically, exposed pixel is determined, including：
It determines in the environment temperature infrared image, the rest of pixels point in addition to the human body pixel point is surrounding pixels
Point；
According to the surrounding pixels point, the environment temperature in first space is determined；
According to mapping rule, the corresponding exposed determining reference value of the environment temperature is determined；
Determine that higher than the human body pixel point of the exposed determining reference value be the initial exposed pixel.
First, by environment infrared image, the rest of pixels point in addition to human body pixel point is such as schemed as surrounding pixels point
Pixel shown in "~" in 3.Then, according to the temperature of each surrounding pixels point, the temperature of all surrounding pixels points is obtained
Average value, using average value as the environment temperature in the first space.
Next, determining the corresponding exposed determining reference value of the environment temperature in current first space according to mapping rule.
In the embodiment of the present application, mapping rule can be that environment temperature is multiplied by preset multiple.Preset multiple is, for example, 1.5 times, 1.25 times
Deng.Alternatively, default rule can also be as follows：
When 20 ° of te≤24 ° ＜, t0=30 °；
When 24 ° of te≤30 ° ＜, t0=32 °；
When 30 ° of te≤35 ° ＜, t0=36 °.
Wherein, te is environment temperature, and t0 is exposed determining reference value.
In the embodiment of the present application, the corresponding exposed judgement benchmark of environment temperature can also be determined according to other mapping rules
Value.The those of ordinary skill in herein described field can be according to being actually configured, and the application is not particularly limited.
As an example it is assumed that the environment temperature in the first space is 24 degree, then being determined according to formula above exposed
Determining reference value is 30 degree.Compare each human body pixel point, will be above 30 degree of human body pixel point and be used as initial exposed pixel,
Such as pixel shown in " * " in Fig. 3.
Finally, each human body pixel point is compared with exposed determining reference value, determines and is higher than exposed determining reference value
Human body pixel point as initial exposed pixel.
In order to judge whether children kick quilt, further include after S103：
Relative position based on the human body pixel point in the environment temperature infrared image, determines the infrared array
The monitoring scanning area of scanning is monitored within multiple monitoring periods, the monitoring scanning area is in first space
One region, and the user is located in the monitoring scanning area；
Within the current monitor period, controls the stepper motor and drive the infrared array in the monitoring scanning area pair
Rotary scanning in the angle answered obtains the monitoring infrared image of the monitoring scanning area；
According to the monitoring infrared image, it is determined whether the first object temperature of the air-conditioning current setting is adjusted to high
In the second target temperature of the first object temperature.
Specifically, infrared in environment temperature according to human body pixel point according to the human body pixel point identified in S102
Relative position in image, it will be able to determine region of the user in the first space, such as user in air-conditioning central axes
Clockwise direction angle is the region between 0 to 14 degree, or region shown in fig. 3.
Due to having confirmed the region where children, so, infrared array is when judging whether children kick quilt, just
Entire first space need not be scanned again, and only needs the region where scanning children, that is, monitors scanning area.
Next, within multiple monitoring periods, stepper motor drives infrared array scanning, scanning to obtain monitoring scanning area
Interior monitoring infrared image.Wherein, it is similar with environment temperature infrared image is above obtained how to obtain monitoring infrared image, because
Here just no longer repeat one by one.
In the embodiment of the present application, obtaining monitoring infrared image can be before determining initial exposed pixel, can also
After determining initial exposed pixel, the application those of ordinary skill in the art can be with being actually configured, this Shen
It please be not particularly limited.
Finally, according to monitoring infrared image, it is determined whether the first object temperature of air-conditioning current setting to be adjusted to be higher than
Second target temperature of first object temperature.Specifically, if air-conditioning judges children kicking quilt, by first object temperature tune
It is whole to be such as adjusted to 27 degree from 23 degree to the second target temperature, to improve the temperature in the first space, avoid children's cold；If
Air-conditioning judges that children do not kick quilt, then first object temperature need not be adjusted to the second target temperature.
Wherein, if determining whether to adjust first object temperature to the second target temperature, specifically according to monitoring scan image
Including：
The exposed pixel in the current monitor period is determined from the monitoring infrared image；
Whether the quantity of the exposed pixel is judged higher than adjustment threshold value, and the adjustment threshold value is the initial exposed picture
Vegetarian refreshments with adjustment a reference value and；
When the quantity of the exposed pixel is higher than the adjustment threshold value, the first object temperature is adjusted to by determination
Second target temperature；
When the quantity of the exposed pixel is not higher than the adjustment threshold value, determines and maintain the first object temperature.
Specifically, in the embodiment of the present application, the exposed picture in the current monitor period is determined according to monitoring infrared image
The method of vegetarian refreshments is identical as the initial mode of exposed pixel is determined.Specially judge human body pixel point in monitoring infrared image
Temperature whether be higher than exposed determining reference value, will be above the human body pixel point of exposed determining reference value as exposed pixel.
And judges the exposed pixel in the current monitor period and judge that beginning this week begins the exposed determining reference value of exposed pixel
For same numerical value, such as 30 degree.
After determining the exposed pixel in the current monitor period, then judge the quantity of exposed pixel whether higher than tune
Whole threshold value.Specifically, in the embodiment of the present application, adjustment budget be initial exposed pixel quantity and with adjustment benchmark
The sum of.During specific implementation, adjustment benchmark can be 1.5-2.5 times of initial exposed pixel quantity.For example, false
If the quantity of initial pixel point is 7, then adjustment benchmark can be 10.5-17.5, and then it is 17.5-24.5 to adjust threshold value just
In arbitrary value.
Then, judge exposed pixel and adjust the relationship of threshold value.Specifically, when the quantity of exposed pixel is higher than tune
When whole threshold value, indicate that the uncovered body area of current child is more.Such as initial uncovered body part is head,
It when exposed pixel is higher than adjustment threshold value, indicates that current child has more body part uncovered, is exposed to outer.In order to avoid
Children's cold, air-conditioning determination adjust first object temperature to the second target temperature.
And when the quantity of exposed pixel is not higher than adjustment threshold value, indicate that children do not kick quilt, then air-conditioning still maintains
First object temperature.
As an example it is assumed that adjustment threshold value is 24.The quantity of exposed pixel is 26, higher than adjustment threshold value, then air-conditioning
23 degree of first object temperature is adjusted to 27 degree of the second target temperature；The quantity of exposed pixel is 20, is equal to adjustment threshold value, that
Air-conditioning will be run still according to first object temperature 23.
During specific implementation, it can each monitor the primary exposed pixel quantity of period judgement and adjust the big of threshold value
It is small, to children kicking by when adjust the target temperature of air-conditioning in time.Alternatively, in order to mitigate facility load, it can also be multiple
The period is monitored, after 20 monitoring periods, judges the average value of the exposed pixel quantity in multiple period whether higher than adjustment
Threshold value, and then determine whether to adjust target temperature value, the application is not particularly limited.
Further, after determining maintenance first object temperature, further include：
Obtain the weighted average of the quantity of the exposed pixel and the quantity of the initial exposed pixel；
Using the weighted average as the initial exposed pixel in next monitoring period.
It, will more after determining maintenance first object temperature in order to keep the adjustment threshold value in next monitoring period more acurrate
The initial exposed pixel in new next monitoring period.Specifically, next in the embodiment of the present application to monitor the initial of period
Exposed pixel is the weighted average of the quantity of the exposed pixel in current monitor period and the quantity of initial pixel point.Its
In, the weighted value of the exposed pixel of current period and initial exposed pixel can be default setting, can be carried out by user
Setting, the application are not particularly limited.
As an example it is assumed that the quantity of exposed pixel is 20, the quantity of weighted value 3, initial exposed pixel is 24,
Weighted value is 2, then the weighted average of the two is 21.6.Therefore, the initial exposed pixel in next monitoring period is
21.6。
Optionally, in order to be identified to user's presentation as a result, after S103, further include：
The corresponding display image of the environment infrared image is shown in the display device of the air-conditioning, wherein the people
