  The request environment setting reception unit 401 receives a request (request environment setting) input from the user via the operation unit 41 and transmits the request to the air conditioning control device 2.

(Smartphone processing flow)
FIG. 3 is a flowchart illustrating an example of processing of the smartphone according to the first embodiment.
FIG. 4 is a diagram illustrating an example of a landmark image according to the first embodiment.
FIG. 5 is a diagram illustrating an example of transmission information according to the first embodiment.
Hereinafter, with reference to FIG. 3 to FIG. 5, a flow of processing in which the smartphone 4 transmits a required environment setting based on a user operation to the air conditioning control device 2 will be described.

First, the landmark image acquisition unit 400 of the smartphone 4 acquires a landmark image obtained by cutting out the landmark L from the image captured by the camera 43 (step S10).
As illustrated in FIG. 1, the landmark L includes detection patterns Fa to Fc for detecting the landmark L so that the background and the landmark L can be separated from each other in the image captured by the camera 43. Yes. In the example of FIG. 1, the landmark L has three detection patterns Fa to Fc. However, in other embodiments, if the landmark L can be detected, the landmark L has at least one detection pattern. And may have less than three, or four or more detection patterns.
By referring to the detection patterns Fa to Fc, the landmark image acquisition unit 400 can acquire a landmark image obtained by cutting out only the landmark L, regardless of the position and angle of the image. .

As shown in FIG. 4, the user photographs the landmark L with the camera 43 of the smartphone 4 from the place (user position) where the user is located. Then, the size and shape (tilt, etc.) of the landmark image are deformed according to the user position.
For example, the size of the landmark image becomes smaller than the actual size of the landmark L (vertical width H, horizontal width W in FIG. 1) as the distance from the installation position (landmark position D) of the landmark L increases.
Further, the amount of deformation of the shape of the landmark image increases as the user position moves away from the front of the landmark L (position Pa in FIG. 4). In the example of FIG. 4, the landmark image is deformed so that the elevation angle θ when the user sees the landmark L from the user position decreases as the user position moves away from the front of the landmark L.
Further, the shape of the landmark image changes depending on the height of the user position. For example, as shown in FIG. 4, when the image is taken at the position in front of the landmark L and at the same height (position Pa1) as the landmark L, the upper side and the lower side of the landmark image have substantially the same length. . On the other hand, when the image is taken from a position higher than the landmark L (position Pa2), the landmark image has a trapezoidal shape whose upper base is longer than the lower base, and from a position lower than the landmark L (position Pa3). When photographed, the landmark image has a trapezoidal shape with a lower bottom longer than an upper base.
Thus, the landmark image is image data that can detect the deformation amount of the size and shape according to the user positions Pa to Pc. That is, based on the size and shape of the landmark image, it is possible to detect the three-dimensional position of the user position (the position where the landmark L is photographed). The landmark image is recorded in a file format such as EXIF (Exchangeable image file format), for example, and includes information that can specify the shooting conditions such as the focal length when the landmark L is shot. Thereby, even when the user zooms and photographs the landmark L, the user position can be corrected based on the focal length or the like.
Further, the landmark image acquisition unit 400 may acquire a landmark image and read information recorded in advance on the landmark L (two-dimensional code) using a known two-dimensional code processing technique. . For example, the landmark L includes a landmark ID that can identify the landmark L, a URL for accessing a request environment setting input form, and the like. In this case, the landmark image acquisition unit 400 causes the display unit 42 to display an input form based on the read URL.

  Next, the required environment setting reception unit 401 of the smartphone 4 receives the required environment settings (set temperature, set humidity, set air volume, etc.) input from the user via the operation unit 41 (step S11).

Next, the required environment setting reception unit 401 of the smartphone 4 transmits transmission information including the landmark image and the required environment setting to the air conditioning control device 2 via the communication I / F 44 (step S12).
As shown in FIG. 5, the transmission information includes a user ID (“0001”) that can identify the user who owns the smartphone 4, the landmark image and landmark ID (“000A”) acquired in step S 10, This is information that associates the required environment settings (“set temperature: ** ° C.”, “set humidity: **%”, “set air volume: small”,...) Acquired in step S11.
As the user ID, a unique user ID may be set in advance for each smartphone 4, and different user IDs are automatically allocated when the smartphone 4 and the air conditioning control device 2 start communication. You may do it.

The smartphone 4 executes each process described above every time the user captures the landmark L with the camera 43.
Note that the user may change the requested environment setting multiple times without moving from the current user position. In this case, the smartphone 4 may read (acquire) a landmark image captured in the past from the storage unit 45 in step S10.

FIG. 11 is a third flowchart illustrating an example of processing of the indoor unit control unit according to the first embodiment.
Hereinafter, with reference to FIG. 6 to FIG. 11, a flow of processing for controlling the air conditioning indoor unit 3 based on transmission information received from the smartphone 4 by the air conditioning control device 2 will be described.

  First, the position estimation unit 200 of the air conditioning control device 2 receives transmission information from the smartphone 4 via the communication I / F 21 (step S20).

Next, the position estimation unit 200 of the air conditioning control device 2 estimates the position (user position) of the sender of the transmission information based on the landmark image included in the transmission information received from the smartphone 4 (step S21). ).
Specifically, the position estimation unit 200 executes each process for estimating the user position shown in FIG.

As illustrated in FIG. 7, the position estimation unit 200 acquires a landmark ID that can identify the landmark L (step S210).
If the transmission information includes a landmark ID, the position estimation unit 200 acquires the landmark ID from the transmission information.
Note that the position estimation unit 200 may read and acquire the landmark ID from the landmark L (two-dimensional code) included in the landmark image using an existing two-dimensional code processing technique. In this case, the landmark information may not be included in the transmission information.

Next, the position estimation unit 200 acquires landmark information associated with the landmark ID from the storage unit 45 (step S211).
As shown in FIG. 8, the landmark information according to the present embodiment includes “landmark ID”, “landmark position”, “image pattern”, and the like.
The landmark position is coordinate information (“x _Da , y _Da , z _Da ”, “x _Db , y _Db , z _Db ) indicating the position (landmark position D in FIG. 9) where the landmark L is installed in the space. "..."
The image pattern is information in which a plurality of different relative positions starting from the landmark position D are associated with sample images that can identify the size and shape of the landmark L when viewed from the relative positions.

Next, the position estimation unit 200 estimates the relative position of the user starting from the landmark position D by performing known image processing on the landmark image (step S212).
For example, as shown in FIG. 9, it is assumed that the user has photographed the landmark L from the position Pc.
At this time, the position estimation unit 200 performs a maximum likelihood estimation by performing pattern matching processing on the landmark image and the image pattern included in the landmark information, thereby estimating the sample image that is most approximate to the landmark image. To extract. Then, the position estimation unit 200 estimates the relative position (the distance r from the landmark position D, the azimuth angle ψ, and the elevation angle θ) associated with the extracted sample image as the relative position of the user.
The position estimation unit 200 determines the size of the landmark image (for example, a ratio based on the vertical width H and the horizontal width W of the landmark L) and the amount of deformation of the shape (for example, the amount of deformation such as the inclination of the landmark image). The relative position of the user may be estimated by calculating the distance r, the azimuth angle ψ, and the elevation angle θ from the landmark position D. In this case, the landmark information may not include the image pattern.

Next, the position estimation unit 200 estimates the user position (“x _pc , y _pc , z _pc ”) based on the relative position from the landmark position D estimated in step S212 (step S213).
And if the position estimation part 200 completes each process which estimates a user position, the air-conditioning control apparatus 2 will complete | finish step S21 of FIG. 6, and will progress to the following step S22.

  Next, as illustrated in FIG. 6, the position acquisition unit 201 of the air conditioning control device 2 acquires the user position estimated by the position estimation unit 200 (step S <b> 22).

  Next, the required environment acquisition unit 202 acquires the required environment setting from the received transmission information (step S23).

Then, the requested environment acquisition unit 202 associates the requested environment setting with the user position acquired by the position acquisition unit 201, and additionally stores the information as user-specific information (FIG. 10) in the storage unit 22 (step S24). ).
As shown in FIG. 10, the user-specific information includes the user ID (“0001”) and the required environment settings (“set temperature: ** ° C.”, “set humidity: **%”, “ This is a table that stores information that associates the set air volume: “small”,...) With the user position (“x _pc , y _pc , z _pc ”) estimated by the position estimation unit 200 for each user.

Next, the indoor unit control unit 203 controls the indoor unit 3 for air conditioning so as to satisfy the user's request as much as possible based on the user position and the required environment setting included in the information for each user (step) S25).
Specifically, the indoor unit control unit 203 executes each process for optimizing the air conditioning shown in FIG.

As shown in FIG. 11, the indoor unit control unit 203 specifies control parameters (a1, a2, a3, a4,...) For minimizing the objective function J (step S250). Here, the control parameters are direct command values for causing the air conditioning indoor unit 3 to be in a desired state, and are, for example, the rotational speed of the fan 30 and the inclination angle of the louver 31.
The objective function J is defined, for example, as in equation (1).

The vector x (i) shown in the equation (1) is a vector quantity indicating the actual temperature, humidity, air volume, etc. at the position where the user i (i = 1, 2,..., N) exists. The vector x (i) includes M elements (x (i) ₁ , x (i) ₂ ,..., X (i) _M ), and each element (x (i) ₁ , x (i) ₂ ,..., X (i) _M ) indicate values (scalar amounts) such as actual temperature, humidity, and air volume at the position where the user i exists. Moreover, as shown in Expression (1), the vector x (i) is uniquely determined by the function F having the control parameters (a1, a2, a3, a4,...) Of the air conditioning indoor unit 3 as input variables.
The vector x * (i) is a vector quantity indicating the temperature, humidity, air volume, etc. desired by the user i. The vector x * (i) is composed of M elements (x ^* (i) ₁ , x ^* (i) ₂ ,..., X ^* (i) _M ), and each element (x ^* (i) ₁ , x ^* (i) ₂ ,..., x ^* (i) _M ) indicates the temperature, humidity, air volume, etc. desired by the user i. More specifically, each element (x ^* (i) ₁ , x ^* (i) ₂ ,..., X ^* (i) _M ) is the set temperature and setting shown in the user-specific information (FIG. 7). Humidity, set air volume, etc.
As shown in the equation (1), the objective function J firstly calculates an error rate ((x (i) _k −x ^* () for each k-th element (k = 1,..., M) of the vector x (i). i) _k ) / x ^* (i) _{Find k} ) and add up all elements. Then, the objective function J is derived by further adding up the sum of the error rates obtained for each user i for all users.
“M” is the number of elements constituting the vector x (i) and the vector x ^* (i), and is the total number of physical quantities that should be set by the user, such as temperature, humidity, and air volume.
“N” is the number of users existing in the space where the indoor unit 3 for air conditioning is installed. More specifically, “N” indicates the number of smartphones 4 detected through ultrasound (the type of user ID). Number).
“Wp (i)” is a weighting coefficient separately defined for each user, and is “1” (equal value) in general operation. However, for example, when an operation that places importance on the demands of elderly users or executive users is performed, the weighting coefficient for each user (i) may be changed.
Further, the method for specifying the minimum value of the objective function J may be based on a well-known search algorithm. The function F may be based on a physical simulation of temperature distribution, humidity distribution, and air volume distribution in a space based on airflow and radiation, for example.

  When the control parameter that minimizes the objective function J is specified, the indoor unit control unit 203 transmits the specified control parameter as a command value to the air conditioning indoor unit 3 and controls it (step S251).

  Thus, whenever the air-conditioning control apparatus 2 receives transmission information from the smartphone 4, the above-described processes are repeatedly executed.

(Function and effect)
As described above, the air conditioning control device 2 according to this embodiment includes the position acquisition unit 201 that acquires the user position estimated by analyzing the landmark image obtained by photographing the landmark L, and the user's request. A required environment acquisition unit 202 that acquires environmental settings, and an indoor unit control unit 203 that controls the indoor unit 3 for air conditioning based on the user position and the required environment settings.
The air conditioning control device 2 according to the present embodiment further includes a position estimation unit 200 that analyzes the landmark image and estimates the user position. The position acquisition unit 201 acquires the user position estimated by the position estimation unit.
In the conventional technology, the location where the landmark is installed (user's location) and the location information stored in the landmark are associated with each other in a one-to-one relationship, so that the location away from the location where the landmark is installed When there is a user, it is difficult to recognize the position of the user. Therefore, in the conventional technology, when there are a plurality of users in a certain space, it is necessary to install a large number of landmarks according to the number of users. Further, it is necessary to update the association between the landmark and the landmark position each time the landmark installation position is changed. As a result, as the number of users (the number of landmarks) in the space increases, the load related to the management of landmarks may increase.
However, according to the air conditioning control device 2 according to the present embodiment, the position estimation unit 200 analyzes the landmark image captured by the user even when the user is located at a position away from the landmark L. Thus, the user position can be estimated.
As a result, a plurality of different user positions can be determined by one landmark L, so that the number of landmarks L can be reduced, and the load related to management of landmark information can be reduced. .

In addition, the indoor unit control unit 203 controls the indoor unit 3 for air conditioning according to each required environment setting requested by a plurality of users.
By doing in this way, even if there are a plurality of users having different requirements (requests for temperature, humidity, air volume, etc.) in the same space, the indoor unit control unit 203 can make each user's request as much as possible. The air conditioner indoor unit 3 can be controlled so that the environment is satisfied.

In the present embodiment, since the user position is estimated by the position estimation unit 402 of the smartphone 4, the landmark image may not be included in the transmission information, unlike the first embodiment.

Moreover, the position acquisition part 201 of the air-conditioning control apparatus 2 will acquire the user position contained in the said transmission information, if transmission information is received from the smart phone 4. FIG.
Even with such a configuration, it is possible to obtain the same effects as those of the first embodiment.

  Moreover, although the air-conditioning control apparatus 2 which concerns on 1st, 2nd embodiment demonstrated that the element used for control was "temperature", "humidity", "air volume", etc., other embodiment is this It is not limited to an aspect.

  In each of the above-described embodiments, the various processes of the air conditioning control device 2 and the smartphone 4 described above are stored in a computer-readable recording medium in the form of a program, and the computer reads and executes this program. By doing so, the various processes described above are performed. The computer-readable recording medium is a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, or the like. Alternatively, the computer program may be distributed to the computer via a communication line, and the computer that has received the distribution may execute the program.

  The program may be for realizing a part of the functions described above. Furthermore, what can implement | achieve the function mentioned above in combination with the program already recorded on the computer system, what is called a difference file (difference program) may be sufficient. Furthermore, in another embodiment, the air conditioning control device 2 and the smartphone 4 may be configured by a single computer, or may be configured by a plurality of computers connected so as to be communicable.

  As mentioned above, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the invention described in the claims and equivalents thereof in the same manner as included in the scope and gist of the invention.

For example, in the above-described embodiment, the aspect in which the size of the landmark L is fixed has been described. However, the present invention is not limited to this. The size of the landmark L may be variable, and the size (vertical width H, horizontal width W) of each landmark L may be included in the landmark information in advance.
Also, the size (vertical width H, horizontal width W) is recorded in advance on the landmark L (two-dimensional code) itself, and the landmark image acquisition unit 400 of the smartphone 4 reads the size using a two-dimensional code processing technique. You may do it. In this case, the requested environment setting reception unit 401 may add information indicating the size of the landmark L to the transmission information and transmit the information to the air conditioning control device 2.
By doing in this way, according to the place where the landmark L is installed, the landmark L of a suitable size can be employ | adopted.

Further, in the above-described embodiment, the aspect in which the landmark L is a two-dimensional code has been described. However, the embodiment is not limited thereto.
In other embodiments, a one-dimensional code or an arbitrary mark may be used as long as the size and shape deformation amount of the landmark L can be detected from the image captured by the camera 43. When the landmark L is an arbitrary mark, it may have any shape as long as the size and position are known. For example, the landmark L may have a shape such as a triangle or a star. Further, a three-dimensional object such as an embedded remote controller, a white board, a copy machine, a wall clock, or a ventilation fan of the air conditioning system 1 installed in the space may be used as the landmark.
Further, the landmark L may be a mark composed only of the detection patterns Fa to Fc shown in FIG. In this case, the detection patterns Fa to Fc are arranged so as to be spaced apart from each other so as to satisfy the specified vertical width H and horizontal width W.

Furthermore, in another embodiment, for example, the panel of the indoor unit 3 for air conditioning, the louver 31 and the like may be used as landmarks. In this case, the position estimation unit 200 of the air conditioning control device 2 or the position estimation unit 402 of the smartphone 4 estimates the user position based on the size and shape deformation amount of the panel or louver 31 included in the landmark image. It may be.
Further, in this case, a mark (seal, logo mark, LED lamp) serving as a mark on at least one place on the panel or louver 31 so that the user can easily detect from which direction the air-conditioning indoor unit 3 has been photographed. The sensor (infrared sensor, ultrasonic sensor, camera) provided in the indoor unit 3 for air conditioning may be used as a substitute for the mark.
When the louvers 31 are provided in the four directions of the air conditioning indoor unit 3, the difference in the opening degrees of the four louvers 31 may be detected from the landmark image. In this case, the position estimation unit 200 (position estimation unit 402) compares the current control state of the air conditioning indoor unit 3 with the respective opening degrees of the louvers 31, and the user has taken the landmark from which direction. To detect.
By doing in this way, since the air conditioning indoor unit 3 itself can also serve as a landmark, it is possible to reduce the cost of producing and installing the landmark L.
