FIG. 4 is a diagram showing a processing flow of the smartphone according to the first embodiment.
Moreover, FIG. 5 is a figure which shows the data structure of the 1st transmission information which the smart phone which concerns on 1st Embodiment transmits.
The processing flow of the smartphone 4 according to the first embodiment is repeatedly executed, for example, from the time when the user who has entered the space activates a dedicated application.

The reception processing unit 401 of the smartphone 4 (CPU 40) waits for the input of the request environment setting from the user (step S01: NO). When the input of the request environment setting is received from the user through the operation of the operation unit 41 (touch panel) (step S01: YES), the reception processing unit 401 acquires the input request environment setting. The required environment setting includes the set temperature, the set humidity, the set air volume, and the like input by the user who holds the smartphone 4.
Next, the radio wave transmission processing unit 402 of the smartphone 4 adds a user ID to the required environment setting acquired in step S01, and sets the required environment setting to which the user ID is added (hereinafter referred to as “first The transmission information is superimposed on the radio wave and transmitted from the wireless communication unit 43 (step S02).
Here, the "first transmission information" has, for example, a data structure as shown in FIG. Specifically, in the first transmission information, the user ID (“UID 0001”), the set temperature (“○ ° C”) input by the user, the set humidity (“%%”), the set air volume (“○%”) "Small" etc. are associated. The user ID may be randomly determined, for example, when the dedicated application is activated, or may be individual identification information assigned to the main body of the smartphone 4 in advance.
The first transmission information is encoded by amplitude modulation, frequency modulation, phase modulation or the like in the wireless communication unit 43, superimposed on radio waves, and transmitted.

When the transmission of the radio wave (the one on which the first transmission information is superimposed) in step S02 is completed, the radio wave transmission processing unit 402 determines whether the answerback has been received from the air conditioning control device 2 within a predetermined time. It determines (step S03). The answer back process of the air conditioning control device 2 will be described later.
When the answer back is received from the air conditioning control device 2 within the prescribed time (step S03: YES), it is determined that the first transmission information is normally recognized by the air conditioning control device 2, and the smartphone 4 The process proceeds to processing (step S05 and subsequent steps).
On the other hand, when the answer back is not received from the air conditioning control device 2 within the prescribed time (step S03: NO), the first transmission information transmitted in step S02 was not correctly recognized by the air conditioning control device 2 It is judged as a thing. Therefore, after waiting for a predetermined time (step S04), the radio wave transmission processing unit 402 superimposes the first transmission information including the request environment setting received in step S01 on the radio wave and transmits it (step S02). The radio wave transmission processing unit 402 repeatedly executes the processing of steps S02 to S04 until the answer back is received from the air conditioning control device 2.
In the present embodiment, the waiting time in step S04 may be randomly determined each time, for example, on the order of several seconds to several tens of seconds.

Next, the process according to steps S05 to S08 in FIG. 4 will be described later.

(Processing flow of air conditioning control device)
FIG. 6 is a diagram showing a process flow of the air conditioning control device according to the first embodiment.
Moreover, FIG. 7 is a figure which shows the data structure of the information classified by user which the indoor unit control apparatus which concerns on 1st Embodiment acquires.
Moreover, FIG. 8 is a figure which shows the data structure of the answer back which the indoor unit control apparatus based on 1st Embodiment transmits.
Moreover, FIG. 9 is a figure for demonstrating the function of the indoor unit control part which concerns on 1st Embodiment.
Hereinafter, the process flow of the air conditioning control device 2 will be described in detail with reference to FIGS. 6 to 9.

The processing flow shown in FIG. 6 is regularly and repeatedly executed from the time of activation of the air conditioning control device 2, the air conditioning indoor unit 3, and the like.

The radio wave detection processing unit 201 of the air conditioning control device 2 (CPU 20) waits for reception of the radio wave (see step S02 in FIG. 4) transmitted from the smartphone 4 (step S11: NO). Specifically, the radio wave detection processing unit 201 receives the radio waves from the smartphone 4 when the plurality of radio communication devices 32 (FIGS. 1 and 2) provided at various places in the space receive the radio communication device 32. Monitors the reception detection signal output to the air conditioning control device 2, and when the reception detection signal is received, it is determined that the radio wave is received from the smartphone 4.

When the radio wave from the smartphone 4 is received (step S11: YES), the position estimation unit 202 of the air conditioning control device 2 determines the phase difference of the radio wave received from each of the plurality of wireless communication devices 32 (FIG. 1, FIG. 2) The position estimation of the smartphone 4 that has transmitted the radio wave is performed based on the reception intensity of the radio wave and the like (step S12). Specifically, the radio communication device 32 provided at each place in the space detects the phase and the reception intensity of the received radio wave as the radio wave is received, and puts the information on the received detection signal to control the air conditioning control device. 2 (the position estimation unit 202). When the position estimation unit 202 receives a reception detection signal including information on the phase and intensity of the received radio wave from each wireless communication device 32, the position estimation unit 202 determines the position of the smartphone 4 that has transmitted the radio wave based on the information on the phase difference and reception strength ( Estimate the terminal position).
The method of estimating the position of the transmission source of the radio wave based on the detection results of the radio wave (phase difference, radio wave reception intensity) in a plurality of sensors is a known technique, and thus detailed description will be omitted.

The position estimation unit 202 records and holds the estimation result of the terminal position (hereinafter referred to as “estimated terminal position”) obtained through the process of step S12.

Next, the radio wave detection processing unit 201 reads the transmission information encoded in the radio wave emitted from the smartphone 4 through the wireless communication device 32 (step S13), and the “required environment setting” is included in the read information. It is determined whether the "specified position" (described later) is included (step S14).
Here, when the radio wave including the first transmission information ("user ID" + "environment supply setting") is transmitted from the smartphone 4 of the user (step S02 in FIG. 4), the radio wave detection processing unit 201 “Required environment setting” is read in step S13 (step S14: required environment setting). In this case, the required environment acquisition unit 203 of the air conditioning control device 2 associates the “estimated terminal position” obtained in step S12 with the “user ID” and the “required environment setting” read here, and then uses the user. Newly added to the separate information (step S15).
As shown in FIG. 7, the user-specific information includes estimated terminal positions (“X1, Y1”) and set temperatures (“○○”) for different user IDs (“UID 0001”, “UID 0002”, “UID 0003”). ° C.), set humidity (““% ”), set air volume (“ small ”), etc. are associated with one another.

When various information (user ID, estimated terminal position, request environment setting) obtained through steps S11 to S15 are normally added to the user-specific information, the estimated terminal position notification unit 205 of the air conditioning control device 2 Answerback is performed by radio waves through any one of the wireless communication devices 32 (step S16). The smartphone 4 can recognize that the air conditioning control device 2 has correctly recognized the estimated terminal position, the user ID, and the required environment setting by receiving the answer back (see FIG. 4). See step S03).
Here, the estimated terminal position notification unit 205 transmits an answerback including, for example, the user ID and the terminal position (estimated terminal position) estimated by the position estimation unit 202 in step S12 as shown in FIG. Details of the processing of the smartphone 4 that has received the answerback including the estimated terminal position will be described later.

Next, the indoor unit control unit 204 of the air conditioning control device 2 controls the air conditioning indoor unit 3 based on user-specific information including the new user's terminal position (estimated terminal position) and required environment setting, and performs air conditioning Optimization (step S17). The process of step S17 will be described in detail with reference to FIG.

As shown in FIG. 9, the indoor unit control unit 204 specifies control parameters (a1, a2, ab3, a4,...) For minimizing the objective function J (step S171). Here, the control parameter is a direct command value for bringing the air conditioning indoor unit 3 into a desired state, and is, for example, the number of rotations of the fan 30, the inclination angle of the louver 31, or the like.
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 and the like at the position where the user i (i = 1, 2,..., N) exists. The vector x (i) consists of 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. Further, as shown in the equation (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.
Further, vector x ^* (i) is a vector quantity indicating the temperature, humidity, air volume, etc. desired by the user i. The vector x ^* (i) consists 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 flow, etc. desired by the user i. More specifically, each element (x ^* (i) ₁ , x ^* (i) ₂ , ..., x ^* (i) _M ) is the setting temperature shown in the user-specific information (FIG. 7), setting Humidity, set air volume, etc.
As shown in the equation (1), the objective function J first generates an error rate ((x (i) _k −x ^* ( _K ) for each kth element (k = 1,..., M) of the vector x (i) i) _{Find k} ) / x ^* (i) _k ) and add up all the elements. Then, the objective function J is derived by further adding up the sum of the above error rates obtained for each user i by all the 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 such as temperature, humidity, and air volume that the user should set.
“N” is the number of users present in the space where the air conditioning indoor unit 3 is installed, and more specifically, the number of smartphones 4 detected through ultrasonic waves (type of user ID Number).
“Wd (i, k)” is a weighting coefficient separately defined for each element, and in general operation, it is all “1” (equal value). However, for example, each user may set “Wd (i, k)” for each element (temperature, humidity, air flow,...) To reflect the preference as to which physical quantity is to be emphasized. With this weighting factor Wd (i, k), even the same person, for example, "wants to particularly fulfill the demand for" wind volume "when returning from a hot outdoor area", "prefers" humidity "during the rainy season" It is possible to respond to detailed requests such as "want them to be the value of preference".
“Wp (i)” is a weighting coefficient separately specified for each user, and in general operation, it is all “1” (equal value). However, for example, in the case of operation where importance is placed on the needs of elderly users and users of executive officers, the weighting coefficient for each user i may be changed.
Also, the method of identifying the minimum value of the objective function J may be based on a well-known search algorithm. The function F may be based on physical simulation of air flow, temperature distribution in space based on radiation, humidity distribution, air volume distribution, for example.

When the control parameter that minimizes the objective function J is specified, the indoor unit control unit 204 transmits the specified control parameter as a command value to the air conditioning indoor unit 3 and performs control (step S172).

The processing flow (steps S18 and S19) performed when the "specified position" is read in step S13 (step S14: specified position) will be described later.

(Position specification function)
FIG. 10 and FIG. 11 are a first diagram and a second diagram, respectively, for explaining the position designation function of the smartphone according to the first embodiment.
Moreover, FIG. 12 is a figure which shows the data structure of the 2nd transmission information which the smart phone which concerns on 1st Embodiment transmits.

Next, in addition to FIG. 4, the process according to steps S05 to S07 of the smartphone 4 will be described in detail with reference to FIGS. 10 to 12.
When the answer back (FIG. 8) is received from the air conditioning control device 2 in step S03 in FIG. 4, the display processing unit 403 of the smartphone 4 displays the display based on the estimated terminal position (see FIG. 8) included in the answer back. The map of the room where the user exists and the image showing the estimated position of the user (the position specified by the estimated terminal position) are displayed at 42 (step S05).
Specifically, as shown in FIG. 10, the display processing unit 403 causes the display unit 42 of the smartphone 4 to display a map image R of a room and a marker image P1 indicated in the estimated terminal position.
By confirming the image as shown in FIG. 10, the user can determine whether the air conditioning control device 2 can correctly estimate the position of the user.
In addition, the information which concerns on the map image R may be made into the aspect sequentially transmitted to the smart phone 4 from the air-conditioning control apparatus 2. FIG. Specifically, the air conditioning control device 2 records and holds in advance a map for each space (room) to be managed by the air conditioning. Then, when the radio wave is received from the smartphone 4, the air conditioning control device 2 places the map image R corresponding to the space where the user is present on the answerback together with the estimated terminal position based on the detection result of the radio wave. It may be sent.

Next, the reception processing unit 401 of the smartphone 4 determines whether the specification of the position where the user is present has been received by the user's own input (step S06).

Here, it is known that radio wave intensity is spatially distorted due to reflection, interference and the like of radio waves on walls, ceilings, installation objects and the like in a space. Under the influence of the distortion of the radio wave intensity, it is assumed that the estimation result of the position based on the radio wave emitted from the smartphone 4 largely deviates from the actual position of the user. Therefore, the user corrects the position (estimated terminal position) when the position estimated by the air conditioning control device 2 (the position shown in the marker image P1 in FIG. 10) is largely deviated from the actual position. The smartphone 4 is operated to directly designate the true position of the user.
Specifically, as shown in FIG. 11, the reception processing unit 401 receives the user's touch operation on the operation unit 41 (touch panel), and receives specification of the current position of the user (step S06: YES). . In this case, the user specifies the position of the user by touching the predetermined position of the map image R displayed on the display unit 42 with a finger. The display processing unit 403 may display the position of the user directly designated (touched) through the operation unit 41 (hereinafter referred to as “designated position”) as a new marker image P2 (see FIG. 11). .
When receiving the designation of the position from the user through the operation unit 41, the radio wave transmission processing unit 402 attaches the user ID to the designated position acquired in step S06, and the designated position to which the user ID is attached ( This is referred to as “second transmission information”) superimposed on radio waves and transmitted from the wireless communication unit 43 (step S07).
Here, the "second transmission information" has, for example, a data structure as shown in FIG. Specifically, in the second transmission information, the user ID (“UID 0001”) is associated with the designated position (“Xa1, Ya1”) input by the user.

Next, with reference to FIG. 6 again, the process according to steps S18 to S19 of the air conditioning control device 2 will be described in detail.
When a radio wave including the second transmission information ("user ID" + "specified position") is transmitted from the user's smartphone 4 (step S07 in FIG. 4), the radio wave detection processing unit 201 performs the step in FIG. The "specified position" is read in S13 (step S14: specified position). In this case, the position estimation unit 202 of the air conditioning control device 2 selects the “estimated terminal position” (“X1” of the user indicated by the “user ID” of the second transmission information in the user-specific information (FIG. 7)). , Y1 ′ ′ is replaced with the position (“Xa1, Ya1”) indicated by the “specified position” of the second transmission information, and correction processing is performed (step S18).
When “estimated terminal position” is normally replaced with “designated position”, radio wave detection processing unit 201 of air conditioning control device 2 transmits an answer back indicating that the correction processing of the terminal position in step S 18 is normally completed ( Step S19). By this answerback, the smartphone 4 recognizes that the position (estimated terminal position) of the user estimated by the air conditioning control device 2 is updated (corrected) to the position (designated position) designated by the user himself. be able to.

Further, the indoor unit control unit 204 of the air conditioning control device 2 controls the air conditioning indoor unit 3 based on the user-specific information (the estimated terminal position is updated to the designated position) newly updated in step S18. (Step S17).

(Action / effect)
As described above, the CPU 20 (position estimation unit 202) of the air conditioning control device 2 according to the first embodiment is the information received from the smartphone 4 (environment setting terminal), and the position designated by the direct input of the user The "estimated terminal position" is corrected based on the "designated position" indicated.
By doing this, the user himself or herself in an environment where the accuracy of the estimated terminal position based on the detection results of radio waves by the plurality of wireless communication devices 32 may be reduced by the influence on radio waves of walls, ceilings, installation objects, etc. It can be easily corrected by the direct specification of the position of.
As described above, according to the air conditioning control device 2 according to the first embodiment, the position estimated based on the radio wave emitted from the environment setting terminal can be corrected.

Further, the CPU 20 (estimated terminal position notification unit 205) of the air conditioning control device 2 transmits information indicating the smartphone 4 to the smartphone 4.
By doing this, the user can check the position automatically identified by the air conditioning control device 2 and determine whether the position is correct or not.

Further, the smartphone 4 (environment setting terminal) according to the first embodiment receives designation of the position of the user from the user, and at the same time, transmits a radio wave on which the position (designated position) designated by the user is superimposed. It makes it transmit via the wireless communication unit 43 (transmitter).
By doing this, the user can correct the position (estimated terminal position) of the user estimated by the air conditioning control device 2 by performing the direct specification operation on the smartphone 4.

The smartphone 4 according to the first embodiment receives information indicating the position estimated by the air conditioning control device 2 through the wireless communication unit 43 (receiver) capable of receiving radio waves, and displays the estimated terminal position. Display on the part 42.
By doing this, the user can visually determine and determine whether the position estimated by the air conditioning control device 2 is correct.

Second Embodiment
Next, an air conditioning system according to a second embodiment will be described with reference to FIGS. 13 and 14.

(Data structure of teacher information)
FIG. 13 is a diagram showing a data structure of teacher information collected by the air conditioning control device according to the second embodiment.
The overall configuration and the functional configuration according to the second embodiment are the same as those of the first embodiment (FIGS. 1 to 3), and are not shown.

The CPU 20 (position estimation unit 202) of the air conditioning control device 2 according to the second embodiment learns the tendency of the error between the estimated terminal position and the designated position, and estimates the terminal based on the tendency of the error obtained by the learning Correct the position.

Specifically, the position estimation unit 202 accumulates teacher information as shown in FIG. The teacher information is the difference between the position (estimated terminal position) estimated by the detection result of the radio wave from the smartphone 4 and the position (designated position) corrected (designated) by the user with respect to the estimated terminal position. It is an information table in which a certain “error” (ΔX, ΔY) is associated. When the designated position is not input from the user ("No designation"), as shown in FIG. 13, the error is regarded as zero.

(Data structure of learning information)
FIG. 14 is a diagram showing a data structure of learning information collected by the air conditioning control device according to the second embodiment.

The position estimation unit 202 according to the second embodiment specifies the distribution of the estimated terminal position with a large error based on the accumulated teacher information (FIG. 13). Then, position estimation section 202 calculates the tendency of errors (for example, the average value of "error" (.DELTA.X, .DELTA.Y), etc.) in the distribution of the estimated terminal position where the error is large and Associate and record. By this processing, the position estimation unit 202 generates learning information.
As shown in FIG. 14, the learning information indicates “target range” (Xα1 to Xβ1 and Yα1 to Yβ1) indicating the range of the estimated terminal position to be subjected to the automatic correction and the tendency of the error corresponding to the range. It is associated with the "correction amount" (ΔXe1, ΔYe1).

After the position estimation unit 202 specifies the estimated terminal position based on the radio wave detection result of the radio communication device 32 in the process of step S12 in FIG. 6, the estimated terminal position belongs to the “target range” of the learning information. It is determined whether or not. Then, when the estimated terminal position is included in the “target range”, a result obtained by adding “correction amount” corresponding to the “target range” is acquired as a new estimated terminal position.

By doing this, the air conditioning control device 2 can automatically correct the estimated terminal position based on the accumulated error between the estimated terminal position and the designated position. Therefore, highly accurate position estimation can be performed regardless of distortion of radio waves in space.

For example, although the process flow of the smartphone 4 shown in FIG. 4 has been described as being on standby until the user receives the request environment setting, the process flow is not limited to this mode. For example, the smartphone 4 may periodically transmit a radio wave on which the user ID is superimposed, without receiving a request environment setting from the user.
By doing this, even when the user's position changes, the terminal position is always updated as the latest user's position, so that the environment required by the user can be provided more appropriately. it can.
Further, in this case, the smartphone 4 detects that the position of the user has changed (the user moved) through the built-in acceleration sensor or the like, and uses this as a trigger to transmit a radio wave on which various information is superimposed. It is good also as an aspect.

In addition, the smartphone 4 according to another embodiment displays coordinates on the map image R (in absolute coordinates, relative coordinates, or in a grid like a map, and cuts them into matrix numbers (e.g. C-3). It may be shown, and at the same time, it may have a function capable of specifying the position where it is present by the coordinate value.

In addition, if the user has specified its position through the tap operation, the recognized tap position in the smartphone 4 by the tap operation of the user ( _{"P A"),} will the user wanted to really touch position It is conceivable that there is an error with (“P _D ”). It is considered that such an error (P _A -P _D ) is also derived from the characteristics of the finger for each user. Therefore, in the smartphone 4 according to another embodiment, the smartphone 4 stores the tendency of the error (P _A -P _D ), and applies the “tap position correction”.
By doing this, the user can accurately sense the tap position intended by the user, so that the user's operation load and stress can be reduced.
Incidentally, the above-mentioned deviation (P A _-P _D), for example, a smart phone 4, to the user, provides another mode such as the following, by get operation, can be stored (learned) . (1) Display one point or a plurality of points on the screen.
(2) Touch these in order, and store the amount of deviation between the touched position and the true position of the point.
