Hereinafter, embodiments will be described in detail with reference to the drawings.
The configuration of the air conditioning system 1 according to an embodiment of the present invention will be described.
The air conditioning system 1 according to an embodiment of the present invention is a system for specifying a real environment setting based on each required environment setting requested by each of a plurality of users and each user position where each of the plurality of users exists. It is. And the air conditioning system 1 is a system which controls the indoor unit for air conditioning based on the specified real environment setting. The required environment setting is a setting value of an environment required by the user to realize a desired environment at the user position, and a setting including at least one of temperature, air volume, humidity and wind direction at the user position. It is a value. The actual environment setting is an environment setting value that is actually set in the air conditioning system 1 so that the satisfaction of the entire user who has set the setting value becomes high.
The air conditioning system 1 includes an air conditioning indoor unit 10, environment setting terminals 20a1 to 20an, and an air conditioning control device 30, as shown in FIG. The environment setting terminals 20a1 to 20an are hereinafter collectively referred to as the environment setting terminal 20.
　空調用室内機１０は、各利用者位置に空気を送り出す。
　環境設定端末２０のそれぞれは、空調用室内機１０が設置される室内の利用者位置における要求環境設定を空調制御装置３０に送信する。なお、空調用室内機１０が設置される室内における利用者位置は、その環境設定端末２０を利用する利用者の利用者位置である。
　空調制御装置３０は、実環境設定に基づいて、空調用室内機１０を制御する。 The air conditioning indoor unit 10 delivers air to each user position.
Each of the environment setting terminals 20 transmits to the air conditioning control device 30 the required environment setting at the user position in the room where the air conditioning indoor unit 10 is installed. The user position in the room where the air conditioning indoor unit 10 is installed is the user position of the user who uses the environment setting terminal 20.
The air conditioning control device 30 controls the air conditioning indoor unit 10 based on the actual environment setting.
　空調用室内機１０は、図２に示すように、通信部１０１と、送風機構１０２と、を備える。
　通信部１０１は、空調制御装置３０と通信を行う。通信部１０１は、実環境設定が示す設定値を実現する制御信号を空調制御装置３０から受信する。
　送風機構１０２は、通信部１０１が受信した制御信号に応じた空気を送り出す。 As shown in FIG. 2, the air conditioning indoor unit 10 includes a communication unit 101 and a blower mechanism 102.
The communication unit 101 communicates with the air conditioning control device 30. The communication unit 101 receives, from the air conditioning control device 30, a control signal for realizing the set value indicated by the actual environment setting.
The blower mechanism 102 sends out air according to the control signal received by the communication unit 101.
　環境設定端末２０のそれぞれは、図３に示すように、出力部２０１と、表示部２０２と、入力部２０３と、記憶部２０４と、を備える。環境設定端末２０は、例えば、スマートフォンである。 As shown in FIG. 3, each of the environment setting terminals 20 includes an output unit 201, a display unit 202, an input unit 203, and a storage unit 204. The environment setting terminal 20 is, for example, a smartphone.
　出力部２０１は、通信機能を有し、要求環境設定を空調制御装置３０に送信する。出力部２０１は、超音波振動子を有し、超音波を出力する。出力部２０１は、その超音波に要求環境設定の情報を重畳させることによって、要求環境設定を空調制御装置３０に送信する。なお、本発明の別の実施形態による出力部２０１は、超音波以外の手段（例えば、電波）を用いて要求環境設定を空調制御装置３０に送信してもよい。 The output unit 201 has a communication function, and transmits the required environment setting to the air conditioning control device 30. The output unit 201 has an ultrasonic transducer and outputs an ultrasonic wave. The output unit 201 transmits the required environment setting to the air conditioning control device 30 by superimposing the information of the required environment setting on the ultrasonic wave. Note that the output unit 201 according to another embodiment of the present invention may transmit the required environment setting to the air conditioning control device 30 using means (for example, radio waves) other than ultrasonic waves.
　表示部２０２は、空調制御装置３０に送信する要求環境設定の設定内容を表示する。具体的には、表示部２０２は、図４に示すように、温度、風量、湿度及び風向の要求環境設定を表示する。 The display unit 202 displays the setting contents of the required environment setting to be transmitted to the air conditioning control device 30. Specifically, as shown in FIG. 4, the display unit 202 displays required environment settings of temperature, air volume, humidity, and air direction.
　入力部２０３は、利用者による操作によって指定された温度、風量、湿度及び風向のうち少なくとも１つを含む要求環境設定の入力を受け付ける。入力部２０３は、受け付けた要求環境設定を記憶部２０４に書き込む。
　記憶部２０４は、利用者の要求環境設定を記憶する。 The input unit 203 receives an input of required environment setting including at least one of temperature, air volume, humidity, and air direction designated by an operation by the user. The input unit 203 writes the received request environment setting in the storage unit 204.
The storage unit 204 stores a user's request environment setting.
　空調制御装置３０は、図５に示すように、取得部３０１（要求環境取得部の一例、位置取得部の一例）と、特定部３０２と、制御部３０３と、を備える。 As shown in FIG. 5, the air conditioning control device 30 includes an acquisition unit 301 (an example of a request environment acquisition unit, an example of a position acquisition unit), a specifying unit 302, and a control unit 303.
　取得部３０１は、複数の利用者それぞれが要求する各要求環境設定を取得する。具体的には、取得部３０１は、環境設定端末２０のそれぞれから要求環境設定を取得する。 The acquisition unit 301 acquires each required environment setting requested by each of a plurality of users. Specifically, the acquisition unit 301 acquires the required environment setting from each of the environment setting terminals 20.
　また、取得部３０１は、複数の利用者それぞれが存在する各利用者位置を取得する。
　具体的には、取得部３０１は、３つ以上の超音波受信器（例えば、超音波マイクロフォン）を、例えば空調用室内機１０が設置される室内の天井に備える。取得部３０１は、環境設定端末２０のそれぞれからの超音波を検知する。取得部３０１は、任意の１つの周波数の超音波について各超音波受信器が超音波を検知したタイミングの時間差と、各超音波受信器が設置されている位置と、空調用室内機１０が設置される室内の空間（おもに、空気）を超音波が伝播する速度とに基づいて、超音波の音源である環境設定端末２０の位置、すなわち利用者位置を算出する。
　より具体的には、取得部３０１は、各超音波受信器が検知した超音波のうち特定周波数の超音波を抽出する。取得部３０１は、抽出した超音波の各超音波受信器における位相を特定し、各超音波受信器間の位相差、すなわち超音波の到達時間差を算出する。取得部３０１は、各超音波受信器間の位相差を各超音波受信器間の距離の差に換算する。取得部３０１は、各超音波受信器間の距離の差から利用者位置を推定する。
　取得部３０１は、異なる周波数の超音波のすべてについて、利用者位置を算出する。 Further, the acquisition unit 301 acquires each user position where each of a plurality of users exists.
Specifically, the acquisition unit 301 includes three or more ultrasound receivers (for example, ultrasound microphones), for example, on a ceiling of a room where the air conditioning indoor unit 10 is installed. The acquisition unit 301 detects ultrasonic waves from each of the environment setting terminals 20. The acquisition unit 301 has a time difference between the timings at which each ultrasonic wave receiver detects ultrasonic waves for ultrasonic waves of any one frequency, the position at which each ultrasonic wave receiver is installed, and the indoor unit 10 for air conditioning installed. The position of the environment setting terminal 20 which is the sound source of the ultrasonic wave, that is, the position of the user is calculated based on the space in the room (mainly air) and the velocity at which the ultrasonic wave propagates.
More specifically, the acquisition unit 301 extracts an ultrasonic wave of a specific frequency from among the ultrasonic waves detected by each ultrasonic wave receiver. The acquisition unit 301 specifies the phase of each of the extracted ultrasonic waves at each ultrasonic wave receiver, and calculates the phase difference between the ultrasonic wave receivers, that is, the arrival time difference of ultrasonic waves. The acquisition unit 301 converts the phase difference between the ultrasound receivers into the difference in distance between the ultrasound receivers. The acquisition unit 301 estimates the position of the user from the difference in distance between the ultrasound receivers.
The acquisition unit 301 calculates the user position for all ultrasonic waves of different frequencies.
　なお、取得部３０１は、超音波受信器をＮ個（Ｎ＞３）備えている場合、Ｎ個のうち３つを選択するすべての組み合わせのそれぞれについて利用者位置を推定し、それらの平均値を利用者位置とすればよい。このようにすることで、取得部３０１は、利用者位置の推定をより高精度に行うことができる。 Note that, when N (N> 3) ultrasound receivers are provided, the acquiring unit 301 estimates the user position for each of all combinations of three selected from N, and the average value thereof. The user position should be By doing this, the acquisition unit 301 can estimate the user position with higher accuracy.
　なお、取得部３０１は、複数の同一周波数の超音波を同時に検知した場合には、同一周波数の超音波どうしが干渉し超音波の音源の位置を特定することができない。そのため、取得部３０１は、複数の同一周波数の超音波を同時に検知した場合には、所定時間が経過した後に再度超音波の検知を試みる。この場合、各環境設定端末２０が出力する超音波の周波数が干渉しないように、各超音波の周波数が異なる周波数となるよう、予め各環境設定端末２０に異なる周波数を割り当てればよい。 When the acquisition unit 301 simultaneously detects a plurality of ultrasonic waves of the same frequency, the ultrasonic waves of the same frequency interfere with each other, and the position of the sound source of the ultrasonic wave can not be identified. Therefore, when detecting a plurality of ultrasonic waves of the same frequency at the same time, the acquiring unit 301 tries to detect the ultrasonic waves again after a predetermined time has elapsed. In this case, different frequencies may be allocated to the environment setting terminals 20 in advance so that the frequencies of the ultrasonic waves may be different so that the frequencies of the ultrasonic waves output from the environment setting terminals 20 do not interfere.
　特定部３０２は、各要求環境設定及び各利用者位置に基づいて、要求環境設定を設定した複数の利用者（例えば、全利用者）の利用者位置における環境を要求環境設定に近づける実環境設定を特定する。
　具体的には、特定部３０２は、目標値である各要求環境設定と各利用者位置における実際の環境とのずれを目標関数とし、この目標関数の値が小さい値となる実環境設定を特定する。 The identifying unit 302 is configured to bring the environment at the user position of a plurality of users (for example, all users) who set the required environment setting closer to the required environment setting based on each required environment setting and each user position. Identify
Specifically, the identifying unit 302 identifies the actual environment setting in which the value of the objective function becomes a small value, with the target value being the difference between each required environment setting that is the target value and the actual environment at each user position. Do.
　より具体的には、特定部３０２は、以下の式（１）に示す目標関数Ｊが小さい値となる実環境設定を特定する。 More specifically, the identifying unit 302 identifies a real environment setting in which the target function J shown in the following equation (1) has a small value.

　式（１）に示すベクトルｘ（ｉ）は、利用者ｉ（ｉ＝１，２，・・，Ｎ）が存在する位置における実際の温度、湿度、風量、風向などの各要求環境設定を示すベクトル量である。ベクトルｘ（ｉ）は、Ｍ個の要素（ｘ（ｉ）１，ｘ（ｉ）２，・・，ｘ（ｉ）Ｍ）からなり、各要素（ｘ（ｉ）１，ｘ（ｉ）２，・・，ｘ（ｉ）Ｍ）は、利用者ｉが存在する位置における実際の温度、湿度、風量、風向などの値（スカラー量）を示している。また、式（１）に示すように、ベクトルｘ（ｉ）は、空調用室内機１０の制御パラメータ（ａ１、ａ２、ａ３、ａ４、・・）を入力変数とする関数Ｆによって一意に定まる。なお、風向の数値化は、例えば、上下方向の風向について、最も上側へ向く風向から最も下側へ向く風向までがｎ段階の風向で規定されている場合には、最も上側へ向く風向から最も下側へ向く風向までのｎ段階を１からｎの整数で数値化すればよい。また、風向の数値化は、例えば、左右方向の風向について、最も左側へ向く風向から最も右側へ向く風向までがｍ段階の風向で規定されている場合には、最も左側へ向く風向から最も右側へ向く風向までのｍ段階を１からｍの整数で数値化すればよい。このように風向を数値化すれば、目標とする風向を示す数値と利用者位置における実際の風向が示す数値との差によってずれを表すことができ、温度、風量、湿度などの数値と同様に演算することが可能となる。
　また、ベクトルｘ＊（ｉ）は、利用者ｉが希望する温度、湿度、風量、風向などを示すベクトル量である。ベクトルｘ＊（ｉ）は、Ｍ個の要素（ｘ＊（ｉ）１，ｘ＊（ｉ）２，・・，ｘ＊（ｉ）Ｍ）からなり、各要素（ｘ＊（ｉ）１，ｘ＊（ｉ）２，・・，ｘ＊（ｉ）Ｍ）は、利用者ｉが希望する温度、湿度、風量、風向などを示している。
　式（１）に示すように、目的関数Ｊは、まず、ベクトルｘ（ｉ）の第ｋ要素（ｋ＝１，・・，Ｍ）ごとに誤差率（（ｘ（ｉ）ｋ－ｘ＊（ｉ）ｋ）／ｘ＊（ｉ）ｋ）を求め、全要素で足し合わせる。そして、目的関数Ｊは、利用者ｉごとに求められた上記誤差率の総和を、更に全利用者で足し合わせることによって導出される。
　“Ｍ”は、ベクトルｘ（ｉ）、ベクトルｘ＊（ｉ）を構成する要素の数であって、温度、湿度、風量、風向など、利用者が設定の対象とすべき物理量の総数である。
　“Ｎ”は、空調用室内機１０が設置された空間内に存在する利用者の人数であって、より具体的には、超音波を通じて検知された環境設定端末２０の台数である。
　“Ｗｄ（ｉ，ｋ）”は、要素別に別途規定された重み付け係数であり、一般的な運用では、全て“１”（等しい値）とされる。しかし、例えば、各利用者が要素（温度、湿度、風量、風向・・）ごとに“Ｗｄ（ｉ，ｋ）”を設定して、どの物理量を重視するかという好みを反映させてもよい。この重み付け係数Ｗｄ（ｉ，ｋ）によって、例えば、同じ人でも、「暑い屋外から戻ってきたばかりのときには『風量』の要望を特に叶えてほしい」とか、「梅雨の時期には『湿度』を優先的に好みの値にしてほしい」といった細かな要望にも応えることが可能となる。
　“Ｗｐ（ｉ）”は、利用者別に別途規定された重み付け係数であり、一般的な運用では、全て“１”（等しい値）とされる。しかし、例えば、熱中症になり易い利用者、高齢の利用者、重役の利用者などの要求を重視する運用を行う場合などにおいては、利用者ｉごとの重み付け係数を変化させてもよい。
　また、温度、風量、湿度、風向などの設定が正規化され、例えば、設定項目のうち温度を重視する場合には、温度の重み付け係数ｗｉを風量、湿度、風向などの温度以外の重み付け係数ｗｉよりも大きくするものであってもよい。
　また、空調用室内機１０が設置される室内において、吹き出し口がＬ個（Ｌ＞１）存在する場合には、それぞれの吹き出し口ごとに温度、風量、湿度、風向などの実環境設定を設定するものであってもよい。
　特定部３０２は、空調用室内機１０が設置される室内における気流及び熱放射をモデル化し、そのモデルのモデルパラメータを変化させて、空調用室内機１０が設置される室内の各利用者位置における所定時間後の温度、風量、湿度、風向などの実際の値をシミュレーションにより算出する。このとき、空調用室内機１０が設置される室内において、吹き出し口がＬ個（Ｌ＞１）存在する場合には、それぞれの吹き出し口ごとの温度、風量、湿度、風向などの実環境設定の組み合わせをさまざまに変更する。なお、空調用室内機１０が設置される室内における気流及び熱放射のモデル化は、理論的に正しいことが確認されている式や予め実験などを行うなどして、モデルパラメータを用いてモデル化すればよい。
　特定部３０２は、変更したさまざまな実環境設定の組み合わせについてシミュレーションにより算出したそれぞれの設定項目について、特定した目標関数Ｊが小さい値となる実環境設定を特定する。なお、目標関数Ｊが小さい値となる実環境設定を特定する際に特定部３０２が用いるアルゴリズムは、正しい実環境設定を特定することができる範囲において限定しない。特定部３０２は、山登り法、シミュレーテッド・アニーリング（ＳＡ法）、遺伝的アルゴリズム（ＧＡ）、同時摂動確率近似（ＳＰＳＡ）アルゴリズムなどを用いるものであってよい。関数Ｆは、例えば、気流、放射熱に基づく空間内の温度分布、湿度分布、風量分布の物理シミュレーションに基づくものであってもよい。 The vector x (i) shown in the equation (1) represents each of the required environment settings such as the actual temperature, humidity, air volume, and wind direction at the position where the user i (i = 1, 2,..., N) exists. It is a vector quantity. 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, air volume, and wind direction at the position where the user i is present. 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 10 as input variables. Note that, for the wind direction in the vertical direction, for example, when the wind direction from the uppermost wind direction to the lowermost wind direction is defined by n stages of wind directions, the wind direction from the uppermost wind direction is the largest. It is sufficient to digitize n steps to the downwind direction with an integer of 1 to n. In addition, for the wind direction, for example, when the wind direction from the leftward wind direction to the rightward wind direction is defined by m stages of wind directions for the leftward wind direction, the rightward wind direction from the leftward wind direction The m stages up to the wind direction may be quantified by an integer of 1 to m. If the wind direction is quantified in this way, the difference can be expressed by the difference between the numerical value indicating the target wind direction and the numerical value indicated by the actual wind direction at the user position, and similar to numerical values such as temperature, air volume, humidity, etc. It becomes possible to calculate.
The vector x * (i) is a vector quantity indicating the temperature, humidity, air volume, wind direction, 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 volume, wind direction, etc. desired by the user i.
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 vector x (i) and vector x * (i), and is the total number of physical quantities that the user should set, such as temperature, humidity, air volume, and wind direction. .
“N” is the number of users present in the space where the air conditioning indoor unit 10 is installed, and more specifically, the number of environment setting terminals 20 detected through ultrasonic waves.
“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 volume, wind direction,...) 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 performing an operation which places importance on requirements such as users susceptible to heat stroke, elderly users, users of executive officers, etc., the weighting coefficient for each user i may be changed.
Also, settings such as temperature, air volume, humidity, and wind direction are normalized. For example, when importance is placed on temperature among the setting items, the weighting coefficient wi for temperature is a weighting coefficient wi for other than temperature such as air volume, humidity, and wind direction. It may be made larger than that.
In addition, when there are L outlets (L> 1) in the room where the air conditioning indoor unit 10 is installed, actual environment settings such as temperature, air volume, humidity, and wind direction are set for each outlet. It may be
The identifying unit 302 models air flow and heat radiation in the room in which the air conditioning indoor unit 10 is installed, changes model parameters of the model, and determines the position of each user in the room in which the air conditioning indoor unit 10 is installed. Actual values such as temperature, air volume, humidity, and wind direction after a predetermined time are calculated by simulation. At this time, if there are L outlets (L> 1) in the room where the air conditioning indoor unit 10 is installed, actual environment settings such as temperature, air volume, humidity, air direction, etc. for each outlet are present. Change the combination in various ways. In addition, modeling of air flow and heat radiation in the room where the indoor unit 10 for air conditioning is installed is modeled using model parameters by conducting experiments etc. by performing an experiment etc. which is theoretically confirmed to be correct. do it.
The identifying unit 302 identifies, for each setting item calculated by simulation for various combinations of changed real environment settings, the actual environment setting in which the identified target function J has a small value. Note that the algorithm used by the identification unit 302 when specifying the actual environment setting in which the target function J has a small value is not limited in the range where the correct actual environment setting can be specified.

　次に、本発明の一実施形態による空調システム１の処理について説明する。
　ここでは、図６に示す空調制御装置３０の処理フローについて説明する。 Next, processing of the air conditioning system 1 according to the embodiment of the present invention will be described.
Here, the process flow of the air conditioning control device 30 shown in FIG. 6 will be described.
　入力部２０３は、利用者による操作によって指定された温度、風量、湿度及び風向のうち少なくとも１つを含む要求環境設定の入力を受け付ける。入力部２０３は、受け付けた要求環境設定を記憶部２０４に書き込む。
　記憶部２０４は、利用者の要求環境設定を記憶する。
　出力部２０１は、利用者の要求環境設定の情報を重畳させた超音波を空調制御装置３０に出力する。 The input unit 203 receives an input of required environment setting including at least one of temperature, air volume, humidity, and air direction designated by an operation by the user. The input unit 203 writes the received request environment setting in the storage unit 204.
The storage unit 204 stores a user's request environment setting.
The output unit 201 outputs, to the air conditioning control device 30, an ultrasonic wave on which the information of the user's required environment setting is superimposed.
　取得部３０１は、複数の利用者それぞれが要求する各要求環境設定を取得する（ステップＳ１）。具体的には、取得部３０１は、環境設定端末２０のそれぞれからの超音波を検知し、検知した超音波に含まれる要求環境設定を取得する。 The acquisition unit 301 acquires each required environment setting requested by each of a plurality of users (step S1). Specifically, the acquisition unit 301 detects ultrasonic waves from each of the environment setting terminals 20, and acquires a required environment setting included in the detected ultrasonic waves.
　また、取得部３０１は、複数の利用者それぞれが存在する各利用者位置を取得する（ステップＳ２）。
　具体的には、取得部３０１は、各超音波受信器が検知した超音波のうち特定周波数の超音波を抽出する。取得部３０１は、抽出した超音波の各超音波受信器における位相を特定し、各超音波受信器間の位相差、すなわち超音波の到達時間差を算出する。取得部３０１は、各超音波受信器間の位相差を各超音波受信器間の距離の差に換算する。取得部３０１は、各超音波受信器間の距離の差から利用者位置を推定する。
　取得部３０１は、異なる周波数の超音波のすべてについて、利用者位置を算出する。 Further, the acquisition unit 301 acquires each user position where each of a plurality of users exists (step S2).
Specifically, the acquisition unit 301 extracts an ultrasonic wave of a specific frequency from among the ultrasonic waves detected by each ultrasonic wave receiver. The acquisition unit 301 specifies the phase of each of the extracted ultrasonic waves at each ultrasonic wave receiver, and calculates the phase difference between the ultrasonic wave receivers, that is, the arrival time difference of ultrasonic waves. The acquisition unit 301 converts the phase difference between the ultrasound receivers into the difference in distance between the ultrasound receivers. The acquisition unit 301 estimates the position of the user from the difference in distance between the ultrasound receivers.
The acquisition unit 301 calculates the user position for all ultrasonic waves of different frequencies.
　特定部３０２は、各要求環境設定及び各利用者位置に基づいて、要求環境設定を設定した複数の利用者の利用者位置における環境を要求環境設定に近づける実環境設定を特定する（ステップＳ３）。
　具体的には、特定部３０２は、目標値である各要求環境設定と各利用者位置における実際の環境とのずれを目標関数とし、この目標関数の値が小さい値となる実環境設定を特定する。
　より具体的には、特定部３０２は、式（１）で示した目標関数Ｊが小さい値となる実環境設定を特定する。 The identifying unit 302 identifies, based on each required environment setting and each user position, an actual environment setting that brings the environment at the user position of a plurality of users who set the required environment setting to the required environment setting (step S3). .
Specifically, the identifying unit 302 identifies the actual environment setting in which the value of the objective function becomes a small value, with the target value being the difference between each required environment setting that is the target value and the actual environment at each user position. Do.
More specifically, the identifying unit 302 identifies a real environment setting in which the target function J represented by equation (1) has a small value.
　また、空調用室内機１０が設置される室内において、吹き出し口がＬ個（Ｌ＞１）存在する場合には、特定部３０２は、それぞれの吹き出し口ごとに温度、風量、湿度、風向などの実環境設定を設定する（ステップＳ４）。 Further, when L outlets (L> 1) exist in the room where the air conditioning indoor unit 10 is installed, the identifying unit 302 determines the temperature, the air volume, the humidity, the air direction, etc. for each outlet. The real environment setting is set (step S4).
　特定部３０２は、空調用室内機１０が設置される室内における気流及び熱放射をモデル化し、そのモデルのモデルパラメータを変化させて関数Ｆを算出し、空調用室内機１０が設置される室内の各利用者位置における所定時間後の温度、風量、湿度、風向などの実際の値をシミュレーションにより算出する（ステップＳ５）。このとき、空調用室内機１０が設置される室内において、吹き出し口がＬ個（Ｌ＞１）存在する場合には、それぞれの吹き出し口ごとの温度、風量、湿度、風向などの実環境設定の組み合わせをさまざまに変更する（ステップＳ６）。
　特定部３０２は、変更したさまざまな実環境設定の組み合わせについてシミュレーションにより算出したそれぞれの設定項目について、特定した目標関数Ｊが小さい値となる実環境設定を特定する（ステップＳ７）。 The identifying unit 302 models air flow and heat radiation in the room in which the air conditioning indoor unit 10 is installed, changes model parameters of the model to calculate a function F, and is used in the room in which the air conditioning indoor unit 10 is installed. Actual values such as temperature, air volume, humidity, and wind direction after a predetermined time at each user position are calculated by simulation (step S5). At this time, if there are L outlets (L> 1) in the room where the air conditioning indoor unit 10 is installed, actual environment settings such as temperature, air volume, humidity, air direction, etc. for each outlet are present. The combination is changed variously (step S6).
The identifying unit 302 identifies, for each setting item calculated by simulation for various combinations of changed real environment settings, the actual environment setting in which the identified target function J has a small value (step S7).
　制御部３０３は、特定部３０２によって特定された実環境設定に基づいて、空調用室内機１０を制御する（ステップＳ８）。 The control unit 303 controls the air conditioning indoor unit 10 based on the actual environment setting specified by the specifying unit 302 (step S8).
　以上、本発明の一実施形態による空調システム１について説明した。
　本発明の一実施形態による空調システム１において、空調制御装置３０は、複数の利用者それぞれが要求する各要求環境設定と、複数の利用者それぞれが存在する各利用者位置を取得する。空調制御装置３０は、各要求環境設定及び各利用者位置に基づいて、要求環境設定を設定した複数の利用者の利用者位置における環境を要求環境設定に近づける実環境設定を特定する。空調制御装置３０は、実環境設定に基づいて、空調用室内機を制御する。
　こうすることにより、空調制御装置３０は、空調設定を行う際に、複数の利用者が空調設定の対象となる室内において、利用者全体として満足度の高い空調設定を実現することができる。 The air conditioning system 1 according to the embodiment of the present invention has been described above.
In the air conditioning system 1 according to the embodiment of the present invention, the air conditioning control device 30 acquires each required environment setting requested by each of the plurality of users and each user position where each of the plurality of users exists. The air conditioning control device 30 specifies, based on each required environment setting and each user position, an actual environment setting that brings the environment at the user position of a plurality of users who set the required environment setting to the required environment setting. The air conditioning control device 30 controls the air conditioning indoor unit based on the actual environment setting.
By doing this, when performing the air conditioning setting, the air conditioning control device 30 can realize the air conditioning setting with high satisfaction as the entire user in the room where the plurality of users are targets of the air conditioning setting.
　なお、本発明の一実施形態では、特定部３０２は、目標値である各要求環境設定と実際に設定する設定値である実環境設定とのずれを目標関数とし、この目標関数の値が小さい値となる実環境設定を特定するものとして説明した。しかしながら、本発明の別の実施形態による特定部３０２は、利用者の満足度を数値化して満足度を目標関数とし、目標関数が最大値となる実環境設定を特定するものであってもよい。利用者の満足度の数値化は、例えば、目標値である各要求環境設定と実際に設定する設定値である実環境設定とのずれの逆数を利用者の満足度とすればよい。 In one embodiment of the present invention, the specification unit 302 sets a target function to a difference between each required environment setting that is a target value and a real environment setting that is a setting value that is actually set, and the value of this target function is small. It has been described as specifying a real environment setting to be a value. However, the specifying unit 302 according to another embodiment of the present invention may be a method of quantifying the degree of satisfaction of the user, setting the degree of satisfaction as the target function, and specifying the actual environment setting where the target function is the maximum value. . The degree of satisfaction of the user may be quantified, for example, by taking the reciprocal of the difference between each required environment setting that is the target value and the actual environment setting that is the setting value that is actually set as the user satisfaction level.
　なお、本発明の一実施形態では、取得部３０１は、３つ以上の超音波受信器が超音波を検知するタイミングの差に基づいて、利用者位置を特定するものとして説明した。しかしながら、本発明の別の実施形態では、利用者位置は、以下に示す別の方法を用いて特定されるものであってもよい。
　例えば、環境設定端末２０の表示部２０２に表示された図７に示すようなマップにおいて領域を示す番号で利用者位置を指定する操作を利用者が行う。環境設定端末２０は、利用者が利用者位置を指定する操作に応じて、利用者位置を空調制御装置３０に送信する。そして、取得部３０１は、環境設定端末２０から利用者位置を取得する。なお、図７において、吹き出し口Ｆが示されている。
　また、例えば、環境設定端末２０は、Ｂｌｕｅｔｏｏｔｈ（登録商標）　Ｌｏｗ　Ｅｎｅｒｇｙなどの電波による通信の信号を空調制御装置３０に送信する。そして、取得部３０１は、環境設定端末２０から受信した信号の電波強度に基づいて、利用者位置を特定する。
　また、例えば、空調制御装置３０は、空調用室内機１０が設置される室内の各位置における情報を予め取得し記憶する。また、空調制御装置３０は、各利用者と顔画像とを関連付けて予め記憶する。取得部３０１は、顔認証機能を有し、空調用室内機１０が設置される室内において利用者を顔認証した位置を、その利用者の利用者位置と特定する。
　また、例えば、環境設定端末２０が撮像機能を有し、所定のマーク（例えば、バーコード）を撮像する。環境設定端末２０は、撮像した所定のマークの画像を空調制御装置３０に送信する。取得部３０１は、環境設定端末２０が撮像した画像における所定のマークの変形の仕方と、空調用室内機１０が設置される室内における所定のマークの位置とに基づいて、環境設定端末２０が所定のマークを撮像した位置を特定し、特定した位置を利用者位置と特定する。
　このようにすれば、空調システム１は、利用者位置を特定する際に、特定の方法を用いる必要がなく、状況に応じて方法を選択することができる。 In the embodiment of the present invention, the acquisition unit 301 has been described as specifying the user position based on the difference in timing at which the three or more ultrasonic receivers detect ultrasonic waves. However, in another embodiment of the present invention, the user position may be identified using another method described below.
For example, the user performs an operation of specifying the user position by the number indicating the area in the map as shown in FIG. 7 displayed on the display unit 202 of the environment setting terminal 20. The environment setting terminal 20 transmits the user position to the air conditioning control device 30 in response to the user's operation of specifying the user position. Then, the acquisition unit 301 acquires the user position from the environment setting terminal 20. In FIG. 7, the outlet F is shown.
Further, for example, the environment setting terminal 20 transmits a signal of communication by radio waves such as Bluetooth (registered trademark) Low Energy to the air conditioning control device 30. Then, the acquiring unit 301 specifies the user position based on the radio wave intensity of the signal received from the environment setting terminal 20.
In addition, for example, the air conditioning control device 30 acquires and stores in advance information at each position in the room where the air conditioning indoor unit 10 is installed. Further, the air conditioning control device 30 associates and stores each user and a face image in advance. The acquiring unit 301 has a face authentication function, and specifies the position at which the user is face-authenticated in the room where the air conditioning indoor unit 10 is installed as the user position of the user.
Also, for example, the environment setting terminal 20 has an imaging function, and images a predetermined mark (for example, a bar code). The environment setting terminal 20 transmits the image of the captured predetermined mark to the air conditioning control device 30. The acquiring unit 301 determines the environment setting terminal 20 based on the method of deformation of the predetermined mark in the image captured by the environment setting terminal 20 and the position of the predetermined mark in the room where the air conditioning indoor unit 10 is installed. Identify the position where the mark is imaged, and identify the identified position as the user position.
In this way, the air conditioning system 1 does not need to use a specific method when specifying the user position, and can select a method according to the situation.
