Detailed description of the invention
Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The air-conditioner control method and air-conditioner proposed according to embodiments of the present invention is described with reference to the accompanying drawings.
First the air-conditioner control method proposed the embodiment of the present invention illustrates.Fig. 1 is according to the present invention
The schematic flow sheet of the air-conditioner control method of embodiment.As it is shown in figure 1, the air-conditioner control method of the embodiment of the present invention includes
Following steps:
Step S10, obtains radiation temperature value and the temperature value of human body surface in room.
The temperature of above-mentioned human body surface is the temperature value of body surface, and radiation temperature is that environment surrounded surface is to human body radiation
The temperature of effect.As a example by people is in room, the body of wall of the such as surrounding of the surrounding in now radiation temperature is room, window etc.
Temperature value to human body radiation effect, the two temperature value can read by having the sensor measurement measuring heat picture function
Arrive, such as array infrared sensor module, when its infrared sensor scanning human body or surrounding, heat picture can be obtained, as
Shown in Fig. 7, heat picture can obtain the most each zonule i.e. temperature value of one of them pixel by array arrangement mode, as
The height that the shade of each pixel shown in Fig. 7 illustrates its temperature value is different, and can read the actual temp of each pixel
Value.The heat picture of certain surface area can be obtained equally during thermal infrared sensor scanning human body, because each ground of human body surface
The temperature of side differs, and therefore reflection also differs to the heat picture of correspondence, can when therefore measuring the temperature of human body surface
Obtain in the way of the temperature spot by the measurement human body all pixels of correspondence heat picture is averaged, i.e. the average temperature of human body surface
Angle value represents that human surface temperature is worth.And measuring radiation temperature in room is by the surrounding district in infrared sensor scanning room
After the heat picture that territory such as wall, ceiling, window are formed, remove human body place heat picture part, read the thermal map of remaining part
Then the temperature value of each pixel of picture averages the radiation temperature value just obtained in room, i.e. average radiation in room
Temperature value represents the radiation temperature value in room.
Step S20, obtains the air temperature value near human body.
Ambient temperature value can be detected by air-conditioner in room, the typically temperature by being arranged on air-conditioner passes
Sensor detection obtains, and the ambient temperature value in order to detect according to air-conditioner obtains the air temperature value in room near human body,
Need the running status combining the concrete cooling and warming of air-conditioner to consider because refrigeration and when heating the wind speed of air-supply to human body
Near the impact of air themperature different, and positions different in human body is in during air-supply under refrigeration mode room is also to human body
Neighbouring air themperature impact is very big, and the position impact being in human body in room when heating air-supply is the least, in order to obtain human body
Neighbouring air themperature, needs the cooling and warming pattern specifically combining air-conditioner to consider different influence factors.
The rule of the concrete air temperature value obtained near human body is as follows:
In cooling mode, the position at detection human body place, detection air-conditioner operating air velocity value and ambient temperature value, according to
Described human body position, air-conditioner operating air velocity value and ambient temperature value obtain the air temperature value near human body.
Further, during the position at detection human body place, by the infrared sensor that is arranged on air-conditioner in right and left
The position angle of detection people upwards and people are next with the position angle detecting people in the vertical direction of described infrared sensor
Determine human body position.
Radiation temperature value and the temperature of human body surface in array infrared sensor module is possible not only to read room
Angle value, it is also possible to obtain human body position in room by it.Human body position in room is infrared based on array
The measured value of sensor assembly can pass through two aspect parameter determinations, and one is based on array infrared sensor module lower section thereon
Upwards measure the location parameter of human body；Additionally on direction around, measure human body based on array infrared sensor module
Location parameter.
Fig. 3 show the signal that the location parameter of human body is upwards measured in array infrared sensor module lower section thereon
Figure, in figure, 1 is air-conditioner, the array infrared sensor module that 2 are mounted on air-conditioner, and 3 is human body position, and 4 are
The body of wall of room surrounding, 5 is ground, and array infrared sensor module can detect that the line on above-below direction with position of human body
With the corner dimension of the metope that the air-conditioner of mounted array formula infrared sensor module is fixed, i.e. array infrared sensing in figure
Device module and the line L of position of human body and the angle theta value of the line H the most parallel with fixing air-conditioner metope, again because of air-conditioner
Setting height(from bottom) be the H in a fixed value, i.e. figure be fixed value, its value can by user to air-conditioner install after height carry out
Measure and be input in the control interface of air-conditioner obtain, or can rough estimation obtain, so by H and the value of angle theta
The size of W can be calculated: W=H*tan θ, i.e. acquisition human body position exists relative to air-conditioner by trigonometric function formula
Beeline W value on direction, ground.
Fig. 4 show the signal that array infrared sensor module measures the location parameter of human body on direction around
Figure, in figure, 1 is air-conditioner, the array infrared sensor module that 2 are mounted on air-conditioner, and 3 is human body, and 4 is room surrounding
Body of wall, A1 and A2 is the diverse location point at human body place, and array infrared sensor module can scan inspection in the lateral direction
The maximum visual angle of the scope surveying surrounding and object is fixing, and the angle b3 constituted such as L1 and L4 line in figure is that array is red
Outer sensor module can detect the maximum visual angle of surrounding and object, Dang Renchu difference in a room in the lateral direction
During position, such as A1 and the A2 point in figure, it can be by array in the position in the lateral direction being positioned at maximum angular field of view
Infrared sensor module detection determines, owing to L1 and L4 line is fixing, human body determines with array infrared sensor module
The angle on line and the two limit just can be detected and obtain, when being positioned at A1 point position such as human body, and human body and the infrared biography of array
The size of the angle b1 of line L2 with L1 that sensor module determines can be detected and obtain；When in like manner human body is positioned at A2 point position,
The size of the angle b2 of line L3 with L1 that human body and array infrared sensor module determine can be detected and obtain.So logical
The size crossing angle b1 and b2 is assured that human body position on array infrared sensor module left and right directions, certainly presss from both sides
The not necessarily fixing angle being the line that human body determines with array infrared sensor module and being formed with maximum visual angle left side bearing L1, angle
Degree, it is also possible to be the line that determines with array infrared sensor module of human body with maximum visual angle on the right of the angle of L4 formation continuously
Degree, or the angle that the vertical line of the line that determines with array infrared sensor module of human body and air-conditioning place metope determines
Degree.
The location parameter of human body is upwards measured and on its left side by above-mentioned array infrared sensor module lower section thereon
The location parameter measuring human body in right direction i.e. can determine that human body position in a room.
The position at human body place is determined, further according to air-conditioner operating air velocity value and ring according to human body region in a room
Border temperature value, it is possible to determine the air temperature value near human body under refrigeration mode.Understand according to experiment, when the position at human body place
When putting the closer to air-conditioner place just to position, the air temperature value near human body is the biggest with ambient temperature value deviation；Work as human body
The position at place further away from air-conditioner place just to position time, the air temperature value near human body and ambient temperature value deviation are more
Little.When air-conditioner operating air velocity value is the highest, the air temperature value near human body is the least with ambient temperature value deviation；Work as air-conditioner
When operating air velocity value is the lowest, the air temperature value near human body is the biggest with ambient temperature value deviation.
Specifically, can be different according to human body position in a room, the space in room is divided into several regions, such as figure
Shown in 5, the region in room being divided into 5 regions of A to E, wherein C region is the relatively close air-conditioner region just to position.
It is divided into several grades F, each wind speed scale to have from small to large the operating air velocity value size of air-conditioner and runs wind accordingly
Speed value.In the present embodiment, between the air temperature value near zoning, room and the grade of operating air velocity and human body
Relation, it may be determined that the air temperature value near human body.Such as:
Above table it can be seen that as air-conditioner run some wind speed scale such as 60 time, if human body is positioned at room
Zones of different, it can be seen that the relatively close air-conditioner of human body just air temperature value and ambient temperature value to the C region of position
Difference maximum, and other A, B, D, E zone air temperature values differ the least with ambient temperature value.As being at same when human body
During such as C region, individual region, it is near human body corresponding to 80 grades than operating air velocity when air-conditioner operating air velocity is 100 grade
Air temperature value is little with ambient temperature value deviation value.Obtaining the region residing for current human, and the operation wind that air-conditioning is current
After speed value, can be according to the relation in upper table, it is thus achieved that the air temperature value near human body.
In a heating mode, when detecting the air temperature value near human body, due to the least with the position relationship at human body place,
Therefore without the concern for this parameter, under heating mode, on the air themperature near human body, it determines that newly affect is the fortune of air-conditioner
Row air speed value, owing to the hot blast under heating mode is experienced more sensitive than the cold wind under refrigeration mode is experienced by human body, and to difference
It is obvious that the hot blast wind speed of size experiences difference, is therefore not suitable for taking the computing rule fixed to obtain according to ambient temperature value T1
Take the air temperature value near human body, and need to distinguish calculating according to different wind speed interval.Such as can be according to air-conditioner
Operating air velocity value be divided into 100 grades from small to large according to wind speed, and these 100 grades are divided into 10 intervals, Mei Gequ
Between use different computing rules:
Wherein Ta is the air temperature value near human body, and T1 is ambient temperature value, and c1, c2, c3, c4, c5, c6 are positive
And be not mutually equal.
Knowing according to experiment, when wind speed is the highest, the air themperature near human body is the least with ambient temperature difference, and wind speed is more
Time low, the air themperature near human body is the biggest with ambient temperature difference, the magnitude relationship of the most above-mentioned c1, c2, c3, c4, c5, c6
For c1 ＞ c2 ＞ c3 ＞ c4 ＞ c5 ＞ c6, such as can be as when form above enumerates the occurrence of c1, c2, c3, c4, c5, c6
Under:
| Wind speed interval | Computing rule |
| [1,10] | Ta=T1-11 |
| [11,30] | Ta=T1-9.3 |
| [31,50] | Ta=T1-8.4 |
| [51,70] | Ta=T1-4.1 |
| [71,90] | Ta=T1-2.4 |
| [91,100] | Ta=T1-0.9 |
Step S30, obtains the first of human body according to the difference of radiation temperature in described human surface temperature value and room and dissipates
Heat, obtains the second heat dissipation capacity of human body according to the air temperature value near described human body, according to the first heat radiation of described human body
Amount and the second heat dissipation capacity obtain the heat dissipation capacity of human body.
According to the first law of thermodynamics, the heat dissipation capacity that human body produces is substantially equal to the heat of human consumption, therefore by surveying
The heat of amount human consumption i.e. can get the heat dissipation capacity of human body, and the heat of human consumption can be calculated by below equation:
H=H1+H2
Wherein H1=Φ (Tcl-Tax)
H2=A1*Mh* (A2-Ta)
Wherein H1 is the first heat dissipation capacity of human body, and the most relevant to Tcl and Tax, Tcl is the temperature value of human body surface, Tax
For radiation temperature value, Φ is additional calculations coefficient, and these design factors are some general meters of Studies of Human Body Heat comfortableness research field
Calculate coefficient, as considered the effective radiating area coefficient f_eff of surrounding, the human body area coefficient f_cl, Φ=f_ of dressing
Eff*f_cl, now H1=f_eff*f_cl* (Tcl-Ta), by calculating temperature value Tcl and the radiation of human body surface
The difference of temperature Ta, in conjunction with design factor Φ, obtains the first heat dissipation capacity H1 of human body.H2 is the second heat dissipation capacity of human body, H2's
Calculating the most relevant to the air temperature value Ta near body metabolism rate Mh and human body, wherein body metabolism rate Mh is in the age of people
Relevant, the crowd in all ages and classes stage such as old man is different with youth, A1 and A2 is the fixing design factor introduced, can be by experiment
Obtain.It is determined by the first heat dissipation capacity H1 and the second heat dissipation capacity H2, then has sued for peace and just obtained total heat dissipation capacity H of human body.
Step S40, according to the heat dissipation capacity of described human body, it is thus achieved that the warm-cold sensitivity state of human body.
The warm-cold sensitivity state of human body can be embodied by concrete different value, such as following table:
| Warm-cold sensitivity state value | Warm-cold sensitivity is interval | Thermal comfort |
| -3≤M ＜-2 | Interval 8 | Cold |
| -2 ＜ M≤-1 | Interval 7 | Somewhat cold |
| -1 ＜ M≤0.5 | Interval 6 | Cool |
| -0.5≤M ＜ 0 | Interval 5 | Comfortable |
| 0≤M≤0.5 | Interval 4 | Comfortable |
| 0.5 ＜ M≤1 | Interval 3 | Warm |
| 1 ＜ M≤2 | Interval 2 | Somewhat hot |
| 2 ＜ M≤3 | Interval 1 | Heat |
Upper table is divided into 8 intervals by the size of warm-cold sensitivity state value M, represents the Thermal comfort that human body is different respectively
Feeling, wherein interval 5 is somewhat nice and cool comfort, and interval 6 is somewhat warm comfort.
Owing to the warm-cold sensitivity state of human body is relevant to the heat of human consumption, and the heat of human consumption dissipating equal to human body
Heat, therefore the size of the heat dissipation capacity of human body reflects the warm-cold sensitivity state of people, by early stage air-conditioner R&D process to not
Cold and hot with user feels to carry out experiencing test, and according to the heat radiation value under the cold and hot sensation of the most calculated difference, can
Obtain relational expression therebetween, the such as relational expression of warm-cold sensitivity state value M and heat dissipation capacity H by fitting formula can represent such as
Under:
M=a0+a1H+a2H2+a3H3+…..+anHn
Wherein testing the different design factor value of acquisition according to a0, a1, a2, a3, an, n is positive, and its value is big
Formation fitting formula between H and M data group that little foundation is concrete determines, as N can be with value for 4.By people in above formula
Relational expression between cold and hot inductance value M and heat dissipation capacity H of body, when, after the heat radiation value H being calculated human body, just substituting into above formula
Obtain the warm-cold sensitivity state value M of human body.It should be noted that above-mentioned fitting formula be used merely to illustrate the cold and hot inductance value of human body with
There is certain relation in heat dissipation capacity, not delimit the scope of the invention, can also according to H during previous experiments and M data group
According to other approximating method matchings, it is thus achieved that other fitting formulas.
Step S50, controls air-conditioner according to described warm-cold sensitivity state and runs.
Warm-cold sensitivity state value according to human body, controls the operational factor of air-conditioner, makes the warm-cold sensitivity state value of human body toward relaxing
Suitable interval change, the operational factor of air-conditioner includes the one in design temperature, operating air velocity, wind guide strip state or many
Kind, it is such as 2.5 to be positioned at interval 1 sensation being i.e. in heat, by self-contained air-conditioner when the warm-cold sensitivity state value that human body is current
The ambient temperature that the design temperature of current air-conditioner during design temperature is lowered so that in room reduces so that the warm-cold sensitivity of people
State value is gradually reduced, in being finally maintained at interval 4 so that human body warm-cold sensitivity state changes to comfort conditions.
According to air-conditioner control method of the present invention, by obtaining radiation temperature in the temperature of human body surface and room
Angle value obtains the first heat dissipation capacity of human body, and by the second heat dissipation capacity of the air temperature value acquisition human body near detection human body,
The first heat dissipation capacity according to human body and the heat radiation value of the second heat dissipation capacity acquisition human body of human body, and dissipating according to human body further
Caloric value obtains the current warm-cold sensitivity state value of human body, and the warm-cold sensitivity state value accuracy obtained by this kind of mode is high, goes forward side by side
Warm-cold sensitivity state is repaiied by refrigeration or heating mode that one step is run according to air-conditioner after obtaining warm-cold sensitivity state value
Just so that the warm-cold sensitivity state value of human body be adapted to more accurately current air-conditioner run different temperatures environment, finally by
The current warm-cold sensitivity state value of human body adjusts the operational factor of air-conditioner automatically so that human body is in comfortable state, solves
Supercool or the overheated discomfort that the operational factor of air-conditioner is brought manually is regulated due to user.
Further, with reference to the stream that Fig. 2, Fig. 2 are the air-conditioner control method according to another embodiment of the presently claimed invention

The temperature of above-mentioned human body surface is the temperature value of body surface, and radiation temperature is that environment surrounded surface is to human body radiation
The temperature of effect.As a example by people is in room, the body of wall of the such as surrounding of the surrounding in now radiation temperature is room, window etc.
Temperature value to human body radiation effect, the two temperature value can read by having the sensor measurement measuring heat picture function
Arrive, such as array infrared sensor module, when its infrared sensor scanning human body or surrounding, heat picture can be obtained, as
Shown in Fig. 7, heat picture can obtain the most each zonule i.e. temperature value of one of them pixel by array arrangement mode, as
The height that the shade of each pixel shown in Fig. 7 illustrates its temperature value is different, and can read the actual temp of each pixel
Value.The heat picture of certain surface area can be obtained equally during thermal infrared sensor scanning human body, because each ground of human body surface
The temperature of side differs, and therefore reflection also differs to the heat picture of correspondence, can when therefore measuring the temperature of human body surface
Obtain in the way of the temperature spot by the measurement human body all pixels of correspondence heat picture is averaged, i.e. the average temperature of human body surface
Angle value represents that human surface temperature is worth.And measuring radiation temperature in room is by the surrounding district in infrared sensor scanning room
After the heat picture that territory such as wall, ceiling, window are formed, remove human body place heat picture part, read the thermal map of remaining part
Then the temperature value of each pixel of picture averages the radiation temperature value just obtained in room, i.e. average radiation in room
Temperature value represents the radiation temperature value in room.
Ambient temperature value can be detected by air-conditioner in room, the typically temperature by being arranged on air-conditioner passes
Sensor detection obtains, and the ambient temperature value in order to detect according to air-conditioner obtains the air temperature value in room near human body,
Need the running status combining the concrete cooling and warming of air-conditioner to consider because refrigeration and when heating the wind speed of air-supply to human body
Near the impact of air themperature different, and positions different in human body is in during air-supply under refrigeration mode room is also to human body
Neighbouring air themperature impact is very big, and the position impact being in human body in room when heating air-supply is the least, in order to obtain human body
Neighbouring air themperature, needs the cooling and warming pattern specifically combining air-conditioner to consider different influence factors.
The rule of the concrete air temperature value obtained near human body is as follows:
In cooling mode, the position at detection human body place, detection air-conditioner operating air velocity value and ambient temperature value, according to
Described human body position, air-conditioner operating air velocity value and ambient temperature value obtain the air temperature value near human body.
Further, during the position at detection human body place, by the infrared sensor that is arranged on air-conditioner in right and left
The position angle of detection people upwards and people are next with the position angle detecting people in the vertical direction of described infrared sensor
Determine human body position.

Body of wall, A1 and A2 is the diverse location point at human body place, and array infrared sensor module can scan inspection in the lateral direction
The maximum visual angle of the scope surveying surrounding and object is fixing, and the angle b3 constituted such as L1 and L4 line in figure is that array is red
Outer sensor module can detect the maximum visual angle of surrounding and object, Dang Renchu difference in a room in the lateral direction
During position, such as A1 and the A2 point in figure, it can be by array in the position in the lateral direction being positioned at maximum angular field of view
Infrared sensor module detection determines, owing to L1 and L4 line is fixing, human body determines with array infrared sensor module
The angle on line and the two limit just can be detected and obtain, when being positioned at A1 point position such as human body, and human body and the infrared biography of array
The size of the angle b1 of line L2 with L1 that sensor module determines can be detected and obtain；When in like manner human body is positioned at A2 point position,
The size of the angle b2 of line L3 with L1 that human body and array infrared sensor module determine can be detected and obtain.So logical
The size crossing angle b1 and b2 is assured that human body position on array infrared sensor module left and right directions, certainly presss from both sides
The not necessarily fixing angle being the line that human body determines with array infrared sensor module and being formed with maximum visual angle left side bearing L1, angle

The location parameter of human body is upwards measured and on its left side by above-mentioned array infrared sensor module lower section thereon
The location parameter measuring human body in right direction i.e. can determine that human body position in a room.
The position at human body place is determined, further according to air-conditioner operating air velocity value and ring according to human body region in a room
Border temperature value, it is possible to determine the air temperature value near human body under refrigeration mode.Understand according to experiment, when the position at human body place
When putting the closer to air-conditioner place just to position, the air temperature value near human body is the biggest with ambient temperature value deviation；Work as human body
The position at place further away from air-conditioner place just to position time, the air temperature value near human body and ambient temperature value deviation are more
Little.When air-conditioner operating air velocity value is the highest, the air temperature value near human body is the least with ambient temperature value deviation；Work as air-conditioner
