画像取得部101は、赤外線センサ210から赤外線画像を取得する。例えば、画像取得部101は、撮像を指示する撮像指示情報を、第1通信部15を介して赤外線センサ210に送信する。そして、画像取得部101は、赤外線センサ210が撮像により取得した赤外線画像を、第1通信部15を介して赤外線センサ210から取得する。同様に、画像取得部101は、第1通信部15を介して赤外線センサ220から赤外線画像を取得する。画像取得部101は、画像取得手段の一例である。
The image acquisition unit 101 acquires an infrared image from the infrared sensor 210. For example, the image acquisition unit 101 transmits image pickup instruction information instructing image pickup to the infrared sensor 210 via the first communication unit 15.

空調制御部102は、室内に設置された室内機300の動作を制御する。例えば、空調制御部102は、操作受付部14がユーザから受け付けた操作に従って、室内機300に対する制御内容を決定する。そして、空調制御部102は、室内機300に対する制御内容を示す制御情報を、第2通信部16を介して室内機300に送信する。なお、空調制御部102は、赤外線センサ210から取得された赤外線画像と、赤外線センサ220から取得された赤外線画像と、後述する出力部104が出力する後述する室内機位置情報とに基づいて、室内機300の動作を制御する。空調制御部102は、空調制御手段の一例である。
The air conditioning control unit 102 controls the operation of the indoor unit 300 installed in the room. For example, the air conditioning control unit 102 determines the control content for the indoor unit 300 according to the operation received from the user by the operation reception unit 14. Then, the air conditioning control unit 102 transmits control information indicating the control content for the indoor unit 300 to the indoor unit 300 via the second communication unit 16. The air conditioner control unit 102 is indoors based on an infrared image acquired from the infrared sensor 210, an infrared image acquired from the infrared sensor 220, and indoor unit position information output by the output unit 104, which will be described later. Controls the operation of the machine 300. The air conditioning control unit 102 is an example of the air conditioning control means.
位置推定部103は、画像取得部101が取得した赤外線画像に基づいて、室内機300の位置を推定する。この赤外線画像は、室内機300が調和空気を吹き出しているときに赤外線センサ210が室内を撮像することにより取得される。室内機300の位置は、室内機300の設置位置と、赤外線センサ210に対する室内機300の相対的な位置(以下、適宜「室内機300の相対位置」という。)とを含む概念である。室内機300の設置位置は、部屋において室内機300が設置された位置である。室内機300の相対位置は、赤外線センサ210の設置位置を基準として室内機300の設置位置を相対的に表した位置である。赤外線センサ210の設置位置は、部屋において赤外線センサ210が設置された位置である。
The position estimation unit 103 estimates the position of the indoor unit 300 based on the infrared image acquired by the image acquisition unit 101. This infrared image is acquired by the infrared sensor 210 taking an image of the room while the indoor unit 300 is blowing out conditioned air. The position of the indoor unit 300 is a concept including the installation position of the indoor unit 300 and the relative position of the indoor unit 300 with respect to the infrared sensor 210 (hereinafter, appropriately referred to as “relative position of the indoor unit 300”). The installation position of the indoor unit 300 is the position where the indoor unit 300 is installed in the room. The relative position of the indoor unit 300 is a position relatively representing the installation position of the indoor unit 300 with reference to the installation position of the infrared sensor 210. The installation position of the infrared sensor 210 is the position where the infrared sensor 210 is installed in the room.
室内機300の相対位置は、例えば、赤外線センサ210から室内機300までの距離、赤外線センサ210から見たときの室内機300の高さ、赤外線センサ210と室内機300とを結ぶ直線と水平面とのなす角度等により表現される。また、室内機300が複数存在する場合、室内機300の相対位置は、赤外線センサ210から室内機300までの距離の大小関係、赤外線センサ210から見たときの室内機300の並び方等により表現されてもよい。例えば、室内機300Aの相対位置と室内機300Bの相対位置とが手前側、室内機300Cの相対位置と室内機300Dの相対位置とが奥側と表現されてもよい。又は、例えば、室内機300Aの相対位置は右手前、室内機300Bの相対位置は左手前、室内機300Cの相対位置は右奥、室内機300Dの相対位置は左奥と表現されてもよい。
The relative position of the indoor unit 300 is, for example, the distance from the infrared sensor 210 to the indoor unit 300, the height of the indoor unit 300 when viewed from the infrared sensor 210, the straight line connecting the infrared sensor 210 and the indoor unit 300, and the horizontal plane. It is expressed by the angle formed by infrared rays. When there are a plurality of indoor units 300, the relative position of the indoor unit 300 is expressed by the magnitude relationship of the distance from the infrared sensor 210 to the indoor unit 300, the arrangement of the indoor units 300 when viewed from the infrared sensor 210, and the like. You may. For example, the relative position of the indoor unit 300A and the relative position of the indoor unit 300B may be expressed as the front side, and the relative position of the indoor unit 300C and the relative position of the indoor unit 300D may be expressed as the back side. Alternatively, for example, the relative position of the indoor unit 300A may be expressed as the right front, the relative position of the indoor unit 300B may be expressed as the left front, the relative position of the indoor unit 300C may be expressed as the right back, and the relative position of the indoor unit 300D may be expressed as the left back.
位置推定部103は、画像取得部101が取得した赤外線画像に基づいて、室内機300の相対位置を推定する。例えば、調和空気が暖房空気である場合、室内機300の吹出口310の周囲の部分の温度は、他の部分の温度よりも高い。従って、赤外線画像において、室内機300の吹出口310の周囲の部分は、他の部分に比べて、高い温度で表現される。そこで、位置推定部103は、赤外線画像において高い温度で表現された部分を、室内機300の吹出口310の周囲の部分として、室内機300の相対位置を推定する。なお、位置推定部103は、記憶部12に記憶された機器情報に基づいて、室内機300の相対位置を精度よく推定することができる。機器情報は、室内機300の機種、吹出口310の個数、吹出口310の配置等を示す情報である。
The position estimation unit 103 estimates the relative position of the indoor unit 300 based on the infrared image acquired by the image acquisition unit 101. For example, when the conditioned air is heating air, the temperature of the portion around the outlet 310 of the indoor unit 300 is higher than the temperature of the other portions. Therefore, in the infrared image, the portion around the outlet 310 of the indoor unit 300 is represented at a higher temperature than the other portions. Therefore, the position estimation unit 103 estimates the relative position of the indoor unit 300 by using the portion represented by the high temperature in the infrared image as the peripheral portion of the outlet 310 of the indoor unit 300. The position estimation unit 103 can accurately estimate the relative position of the indoor unit 300 based on the device information stored in the storage unit 12. The device information is information indicating the model of the indoor unit 300, the number of outlets 310, the arrangement of outlets 310, and the like.
また、位置推定部103は、推定した室内機300の相対位置と赤外線センサ210の設置位置とから、室内機300の設置位置を更に推定する。なお、赤外線センサ210の設置位置は、操作受付部14がユーザから受け付ける。赤外線センサ210の設置位置は、例えば、壁630と壁640と壁650とのうちどの壁に赤外線センサ210が設置されたか、壁630のどの位置に赤外線センサ210が設置されたか、天井610から赤外線センサ210までの距離、床620から赤外線センサ210までの距離等により表現される。
Further, the position estimation unit 103 further estimates the installation position of the indoor unit 300 from the estimated relative position of the indoor unit 300 and the installation position of the infrared sensor 210. The operation receiving unit 14 receives the installation position of the infrared sensor 210 from the user. The installation position of the infrared sensor 210 is, for example, which wall of the wall 630, the wall 640, and the wall 650 the infrared sensor 210 is installed, the position of the wall 630 where the infrared sensor 210 is installed, and the infrared rays from the ceiling 610. It is expressed by the distance to the sensor 210, the distance from the floor 620 to the infrared sensor 210, and the like.
なお、記憶部12には、赤外線センサ210の設置位置、室内機300の設置位置等を適切に表現するために必要な情報が記憶されているものとする。例えば、記憶部12は、室内の形状と室内の大きさとを示す室内情報が記憶されているものとする。また、記憶部12には、赤外線センサ220の設置位置を示す情報が記憶されているものとする。
It is assumed that the storage unit 12 stores information necessary for appropriately expressing the installation position of the infrared sensor 210, the installation position of the indoor unit 300, and the like. For example, it is assumed that the storage unit 12 stores indoor information indicating the shape of the room and the size of the room. Further, it is assumed that the storage unit 12 stores information indicating the installation position of the infrared sensor 220.
位置推定部103は、室内における赤外線センサ210の設置位置と、赤外線センサ210から見たときの室内機300の相対的な位置とに基づいて、室内における室内機300の設置位置を推定する。位置推定部103は、4つの室内機300のそれぞれについて、室内における設置位置を推定する。位置推定部103は、位置推定手段の一例である。操作受付部14は、設置位置受付手段の一例である。
The position estimation unit 103 estimates the installation position of the indoor unit 300 in the room based on the installation position of the infrared sensor 210 in the room and the relative position of the indoor unit 300 when viewed from the infrared sensor 210. The position estimation unit 103 estimates the installation position in the room for each of the four indoor units 300. The position estimation unit 103 is an example of the position estimation means. The operation reception unit 14 is an example of the installation position reception means.
出力部104は、室内機300が調和空気を吹き出しているときに赤外線センサ210が室内を撮像することにより取得される赤外線画像に基づく室内機300の位置を示す室内機位置情報を出力する。つまり、出力部104は、位置推定部103が推定した室内機300の相対位置、又は、室内機300の相対位置から求められる室内機300の設置位置を示す室内機位置情報を出力する。
The output unit 104 outputs indoor unit position information indicating the position of the indoor unit 300 based on an infrared image acquired by the infrared sensor 210 taking an image of the room while the indoor unit 300 is blowing out conditioned air. That is, the output unit 104 outputs the indoor unit position information indicating the relative position of the indoor unit 300 estimated by the position estimation unit 103 or the installation position of the indoor unit 300 obtained from the relative position of the indoor unit 300.
例えば、出力部104は、空調制御部102に室内機位置情報を出力する。一方、空調制御部102は、出力部104が出力した室内機位置情報に基づいて、室内機300の動作を制御する。また、出力部104は、表示部13に室内機位置情報を出力する。一方、表示部13は、出力部104が出力した室内機位置情報に基づいて、室内の熱分布と室内機300の位置とを示す熱分布画像を表示する。また、出力部104は、第3通信部17を介して、端末装置500に室内機位置情報を送信する。一方、端末装置500は、出力部104が出力した室内機位置情報に基づいて、室内の熱分布と室内機300の位置とを示す熱分布画像を表示する。出力部104は、出力手段の一例である。表示部13は、表示手段の一例である。
For example, the output unit 104 outputs the indoor unit position information to the air conditioning control unit 102. On the other hand, the air conditioning control unit 102 controls the operation of the indoor unit 300 based on the indoor unit position information output by the output unit 104. Further, the output unit 104 outputs the indoor unit position information to the display unit 13. On the other hand, the display unit 13 displays a heat distribution image showing the heat distribution in the room and the position of the indoor unit 300 based on the indoor unit position information output by the output unit 104. Further, the output unit 104 transmits the indoor unit position information to the terminal device 500 via the third communication unit 17. On the other hand, the terminal device 500 displays a heat distribution image showing the heat distribution in the room and the position of the indoor unit 300 based on the indoor unit position information output by the output unit 104. The output unit 104 is an example of output means. The display unit 13 is an example of display means.
角度制御部105は、赤外線センサ210の設置角度を調整する角度調整部18の動作を制御する。つまり、角度制御部105は、撮像領域に室内機300が含まれるように、角度調整部18の動作を制御する。例えば、角度制御部105は、撮像領域に室内機300が含まれない場合、撮像領域に室内機300が含まれるまで、赤外線センサ210の設置角度を調整する。角度制御部105は、角度制御手段の一例である。角度調整部18は、角度調整手段の一例である。
The angle control unit 105 controls the operation of the angle adjustment unit 18 that adjusts the installation angle of the infrared sensor 210. That is, the angle control unit 105 controls the operation of the angle adjustment unit 18 so that the indoor unit 300 is included in the image pickup region. For example, when the indoor unit 300 is not included in the imaging region, the angle control unit 105 adjusts the installation angle of the infrared sensor 210 until the indoor unit 300 is included in the imaging region. The angle control unit 105 is an example of the angle control means. The angle adjusting unit 18 is an example of the angle adjusting means.
室内機300は、複数の吹出口310を備え、複数の吹出口310毎に風向を調整可能である。この場合、空調制御部102は、室内機300が、複数の吹出口310から調和空気が吹き出され、複数の吹出口310のうち第1吹出口の風向が他の吹出口の風向と異なる第1状態になるように室内機300の動作を制御する。一方、位置推定部103は、室内機300が第1状態であるときに赤外線センサ210が室内を撮像することにより取得される赤外線画像に基づいて、赤外線センサ210に対する第1吹出口の相対的な位置を推定する。そして、出力部104は、位置推定部103が推定した赤外線センサ210に対する第1吹出口の相対的な位置、又は、赤外線センサ210に対する第1吹出口の相対的な位置から求められる第1吹出口の設置位置を示す室内機位置情報を出力する。
The indoor unit 300 is provided with a plurality of outlets 310, and the wind direction can be adjusted for each of the plurality of outlets 310. In this case, in the air conditioning control unit 102, the indoor unit 300 blows out the harmonized air from the plurality of outlets 310, and the wind direction of the first outlet of the plurality of outlets 310 is different from the wind direction of the other outlets. The operation of the indoor unit 300 is controlled so as to be in a state. On the other hand, the position estimation unit 103 is relative to the infrared sensor 210 of the first outlet based on the infrared image acquired by the infrared sensor 210 taking an image of the room when the indoor unit 300 is in the first state. Estimate the position. Then, the output unit 104 is a first outlet obtained from the relative position of the first outlet with respect to the infrared sensor 210 estimated by the position estimation unit 103, or the relative position of the first outlet with respect to the infrared sensor 210. Outputs indoor unit position information indicating the installation position of.
次に、図6のフローチャートを参照して、空調制御装置100が実行する空調制御処理について説明する。空調制御装置100は、例えば、電源が投入されたことに応答して、空調制御処理の実行を開始する。なお、空調制御装置100が空調制御処理を実行することにより、本開示における位置情報出力方法が実現される。
Next, the air conditioning control process executed by the air conditioning control device 100 will be described with reference to the flowchart of FIG. The air conditioning control device 100 starts executing the air conditioning control process, for example, in response to the power being turned on. The position information output method in the present disclosure is realized by the air conditioning control device 100 executing the air conditioning control process.
まず、空調制御装置100が備える制御部11は、位置検出指示があるか否かを判別する(ステップS101)。例えば、制御部11は、操作受付部14が位置検出を指示する位置検出指示操作をユーザから受け付けたか否かを判別する。又は、制御部11は、端末装置500から位置検出を指示する位置検出指示情報を受信したか否かを判別する。又は、起動時に位置検出を実行するようにプログラムされている場合、制御部11は、空調制御装置100が起動直後であるか否かを判別する。
First, the control unit 11 included in the air conditioning control device 100 determines whether or not there is a position detection instruction (step S101). For example, the control unit 11 determines whether or not the operation reception unit 14 has received the position detection instruction operation instructing the position detection from the user. Alternatively, the control unit 11 determines whether or not the position detection instruction information instructing the position detection has been received from the terminal device 500. Alternatively, if the program is programmed to execute position detection at startup, the control unit 11 determines whether or not the air conditioning control device 100 is immediately after startup.
制御部11は、位置検出指示があると判別すると(ステップS101:YES)、赤外線センサ210の設置位置の入力を受け付ける(ステップS102)。例えば、制御部11は、表示部13を制御して、赤外線センサ210の設置位置を問い合わせる画像を表示する。赤外線センサ210の設置位置は、例えば、赤外線センサ210から天井610までの距離により指定される。なお、空調制御装置100の設置位置を示す情報が記憶部12に記憶されている場合、空調制御装置100の設置位置が赤外線センサ210の設置位置として扱われてもよい。制御部11は、赤外線センサ210の設置位置の入力を、操作受付部14を介してユーザから受け付ける。
When the control unit 11 determines that there is a position detection instruction (step S101: YES), the control unit 11 accepts an input of the installation position of the infrared sensor 210 (step S102). For example, the control unit 11 controls the display unit 13 to display an image inquiring about the installation position of the infrared sensor 210. The installation position of the infrared sensor 210 is specified by, for example, the distance from the infrared sensor 210 to the ceiling 610. When the information indicating the installation position of the air conditioning control device 100 is stored in the storage unit 12, the installation position of the air conditioning control device 100 may be treated as the installation position of the infrared sensor 210. The control unit 11 receives an input of the installation position of the infrared sensor 210 from the user via the operation reception unit 14.
制御部11は、ステップS102の処理を完了すると、空調機位置推定処理を実行する(ステップS103)。以下、図7を参照して、空調機位置推定処理について詳細に説明する。
When the control unit 11 completes the process of step S102, the control unit 11 executes the air conditioner position estimation process (step S103). Hereinafter, the air conditioner position estimation process will be described in detail with reference to FIG. 7.
まず、制御部11は、天井面の赤外線画像を取得する(ステップS201)。例えば、制御部11は、赤外線センサ210による撮像範囲に天井面が含まれるように、角度調整部18を制御する。そして、制御部11は、赤外線センサ210に撮像を指示し、赤外線センサ210から天井面を含む赤外線画像を取得する。制御部11は、ステップS201の処理を完了すると室内機300を選択する(ステップS202)。具体的には、制御部11は、4つの室内機300のうち未選択の1つの室内機300を選択する。
First, the control unit 11 acquires an infrared image of the ceiling surface (step S201). For example, the control unit 11 controls the angle adjustment unit 18 so that the ceiling surface is included in the image pickup range of the infrared sensor 210. Then, the control unit 11 instructs the infrared sensor 210 to take an image, and acquires an infrared image including the ceiling surface from the infrared sensor 210. The control unit 11 selects the indoor unit 300 when the process of step S201 is completed (step S202). Specifically, the control unit 11 selects one unselected indoor unit 300 out of the four indoor units 300.
制御部11は、ステップS202の処理を完了すると、選択した室内機300の風向を真横に設定する(ステップS203)。具体的には、制御部11は、選択した室内機300については、全ての吹出口310から真横に調和空気が吹き出されるように、全てのルーバ320の角度を調整する。制御部11は、ステップS203の処理を完了すると、選択していない室内機300の風向を真下に設定する(ステップS204)。具体的には、制御部11は、選択していない全ての室内機300については、全ての吹出口310から真下に調和空気が吹き出されるように、全てのルーバ320の角度を調整する。
When the control unit 11 completes the process of step S202, the control unit 11 sets the wind direction of the selected indoor unit 300 to the side (step S203). Specifically, the control unit 11 adjusts the angles of all the louvers 320 for the selected indoor unit 300 so that the conditioned air is blown out from all the outlets 310 to the side. When the process of step S203 is completed, the control unit 11 sets the wind direction of the unselected indoor unit 300 directly below (step S204). Specifically, the control unit 11 adjusts the angles of all the louvers 320 so that the conditioned air is blown directly below from all the outlets 310 for all the indoor units 300 that have not been selected.
制御部11は、ステップS204の処理を完了すると、調和空気を吹き出す(ステップS205)。例えば、制御部11は、全ての室内機300のそれぞれが備える全ての吹出口310から調和空気が吹き出されるように、全ての室内機300を制御する。本実施の形態では、調和空気は、暖房空気である。
When the control unit 11 completes the process of step S204, the control unit 11 blows out conditioned air (step S205). For example, the control unit 11 controls all the indoor units 300 so that the conditioned air is blown out from all the outlets 310 provided in each of the indoor units 300. In this embodiment, the conditioned air is heating air.
制御部11は、ステップS205の処理を完了すると、天井面の赤外線画像を取得する(ステップS206)。制御部11は、ステップS201と同様の処理により、赤外線センサ210から天井面の赤外線画像を取得する。制御部11は、ステップS206の処理を完了すると、温度変化領域を特定する(ステップS207)。この温度変化領域は、ステップS201で取得された赤外線画像とステップS206で取得された赤外線画像とで、温度の変化により画像が変化した領域である。
When the control unit 11 completes the process of step S205, the control unit 11 acquires an infrared image of the ceiling surface (step S206). The control unit 11 acquires an infrared image of the ceiling surface from the infrared sensor 210 by the same processing as in step S201. When the control unit 11 completes the process of step S206, the control unit 11 identifies the temperature change region (step S207). This temperature change region is a region in which the infrared image acquired in step S201 and the infrared image acquired in step S206 change the image due to the change in temperature.
ステップS201で取得された赤外線画像、つまり、全ての室内機300が調和空気を吹き出す前に取得された赤外線画像では、周囲に比べて高い温度を有する領域が観測されない。一方、ステップS206で取得された赤外線画像では、選択した室内機300に対応する領域が、周囲に比べて高い温度を有する領域として観測される。図8に、室内機300Aが選択されたときにステップS206で取得された赤外線画像である画像710を示す。なお、壁660は、壁650と対向する壁である。
In the infrared image acquired in step S201, that is, the infrared image acquired before all the indoor units 300 blow out the conditioned air, a region having a higher temperature than the surroundings is not observed. On the other hand, in the infrared image acquired in step S206, the region corresponding to the selected indoor unit 300 is observed as a region having a higher temperature than the surroundings. FIG. 8 shows an image 710, which is an infrared image acquired in step S206 when the indoor unit 300A is selected. The wall 660 is a wall facing the wall 650.
画像710では、選択された室内機300Aに対応する領域が、周囲に比べて高い温度を有する領域として観測される。より詳細には、画像710では、室内機300Aが備える吹出口310Aの外側の領域である領域330Aと、室内機300Aが備える吹出口310Bの外側の領域である領域330Bと、室内機300Aが備える吹出口310Cの外側の領域である領域330Cと、室内機300Aが備える吹出口310Dの外側の領域である領域330Dとが、周囲に比べて高い温度を有する領域として観測される。この理由は、室内機300Aが備える吹出口310からは真横に暖房空気が吹き出され、室内機300Aが備える吹出口310の外側の部材の温度が上昇するためである。
In image 710, the region corresponding to the selected indoor unit 300A is observed as a region having a higher temperature than the surroundings. More specifically, in the image 710, the indoor unit 300A includes a region 330A which is an outer region of the outlet 310A included in the indoor unit 300A, a region 330B which is an outer region of the outlet 310B included in the indoor unit 300A, and the indoor unit 300A. The region 330C, which is the region outside the outlet 310C, and the region 330D, which is the region outside the outlet 310D included in the indoor unit 300A, are observed as regions having a higher temperature than the surroundings. The reason for this is that the heating air is blown out right beside the outlet 310 included in the indoor unit 300A, and the temperature of the member outside the outlet 310 included in the indoor unit 300A rises.
これに対して、画像710では、室内機300B、室内機300C及び室内機300Dに対応する領域は、周囲に比べて高い温度を有する領域として観測されない。この理由は、室内機300B、室内機300C及び室内機300Dが備える吹出口310からは真下に暖房空気が吹き出され、室内機300B、室内機300C及び室内機300Dが備える吹出口310の周囲の部材の温度はあまり上昇しないためである。
On the other hand, in the image 710, the region corresponding to the indoor unit 300B, the indoor unit 300C, and the indoor unit 300D is not observed as a region having a higher temperature than the surroundings. The reason for this is that the heating air is blown directly below from the outlet 310 provided in the indoor unit 300B, the indoor unit 300C and the indoor unit 300D, and the members around the outlet 310 provided in the indoor unit 300B, the indoor unit 300C and the indoor unit 300D. This is because the temperature does not rise so much.
制御部11は、ステップS207の処理を完了すると、選択した室内機300の相対位置を推定する(ステップS208)。例えば、選択された室内機300が室内機300Aである場合、画像710では、領域330Aと領域330Bと領域330Cと領域330Dとが、温度変化領域として観測される。制御部11は、画像710上において、領域330Aと領域330Bと領域330Cと領域330Dとにより囲まれた領域を、室内機300Aが設置された領域として特定する。
When the control unit 11 completes the process of step S207, the control unit 11 estimates the relative position of the selected indoor unit 300 (step S208). For example, when the selected indoor unit 300 is the indoor unit 300A, in the image 710, the region 330A, the region 330B, the region 330C, and the region 330D are observed as the temperature change region. The control unit 11 identifies a region surrounded by the region 330A, the region 330B, the region 330C, and the region 330D on the image 710 as the region in which the indoor unit 300A is installed.
なお、領域330Aと領域330Cとは、水平方向に延びる線状の領域として観測される。また、赤外線センサ210が設置された壁630から壁640までの距離に対して、床620から天井610までの距離がそれほど長くない場合、赤外線センサ210と室内機300とを結ぶ直線と水平面とのなす角度がそれほど大きくならないと考えられる。この場合、領域330Aの長さと領域330Cの長さとは、領域330Bの長さと領域330Dの長さとに比べて、長いと考えられる。このため、領域330Aと領域330Cとは、領域330Bと領域330Dとに比べて、画像710から検出しやすい。そこで、制御部11は、水平方向に延びて互いに対向する領域330Aと領域330Cとを画像710から検出し、領域330Aと領域330Cとに挟まれた領域を、室内機300Aの領域として推定することが好適である。
The region 330A and the region 330C are observed as linear regions extending in the horizontal direction. If the distance from the floor 620 to the ceiling 610 is not so long with respect to the distance from the wall 630 to the wall 640 in which the infrared sensor 210 is installed, the straight line connecting the infrared sensor 210 and the indoor unit 300 and the horizontal plane. It is thought that the angle of formation will not be so large. In this case, the length of the region 330A and the length of the region 330C are considered to be longer than the length of the region 330B and the length of the region 330D. Therefore, the area 330A and the area 330C are easier to detect from the image 710 than the area 330B and the area 330D. Therefore, the control unit 11 detects the region 330A and the region 330C extending in the horizontal direction and facing each other from the image 710, and estimates the region sandwiched between the region 330A and the region 330C as the region of the indoor unit 300A. Is preferable.
制御部11は、画像710上における室内機300Aの位置及び大きさに基づいて、室内機300Aの相対位置を推定する。なお、室内機300Aの相対位置は、例えば、赤外線センサ210から室内機300Aまでの距離と、赤外線センサ210と室内機300Aとを結ぶ直線と水平面とのなす角度とにより表現される。
The control unit 11 estimates the relative position of the indoor unit 300A based on the position and size of the indoor unit 300A on the image 710. The relative position of the indoor unit 300A is expressed by, for example, the distance from the infrared sensor 210 to the indoor unit 300A and the angle formed by the straight line connecting the infrared sensor 210 and the indoor unit 300A and the horizontal plane.
制御部11は、ステップS208の処理を完了すると、選択した室内機300の設置位置を推定する(ステップS209)。具体的には、制御部11は、ステップS102で受け付けた赤外線センサ210の設置位置と、ステップS208で推定した選択した室内機300の相対位置とに基づいて、室内における選択した室内機300の設置位置を推定する。
When the control unit 11 completes the process of step S208, the control unit 11 estimates the installation position of the selected indoor unit 300 (step S209). Specifically, the control unit 11 installs the selected indoor unit 300 in the room based on the installation position of the infrared sensor 210 received in step S102 and the relative position of the selected indoor unit 300 estimated in step S208. Estimate the position.
制御部11は、ステップS209の処理を完了すると、未選択の室内機300があるか否かを判別する(ステップS210)。制御部11は、未選択の室内機300があると判別すると(ステップS210:YES)、ステップS202に処理を戻す。制御部11は、未選択の室内機300がないと判別すると(ステップS210:NO)、空調機位置推定処理を完了する。
When the process of step S209 is completed, the control unit 11 determines whether or not there is an unselected indoor unit 300 (step S210). When the control unit 11 determines that there is an unselected indoor unit 300 (step S210: YES), the control unit 11 returns the process to step S202. When the control unit 11 determines that there is no unselected indoor unit 300 (step S210: NO), the control unit 11 completes the air conditioner position estimation process.
制御部11は、ステップS103の空調機位置推定処理を完了すると、吹出口位置推定処理を実行する(ステップS104)。以下、図9を参照して、吹出口位置推定処理について詳細に説明する。
When the control unit 11 completes the air conditioner position estimation process in step S103, the control unit 11 executes the air outlet position estimation process (step S104). Hereinafter, the outlet position estimation process will be described in detail with reference to FIG.
まず、制御部11は、天井面の赤外線画像を取得する(ステップS301)。制御部11は、ステップS301の処理を完了すると、室内機300を選択する(ステップS302)。制御部11は、ステップS302の処理を完了すると、吹出口310を選択する(ステップS303)。具体的には、制御部11は、4つの吹出口310のうち未選択の1つの吹出口310を選択する。
First, the control unit 11 acquires an infrared image of the ceiling surface (step S301). When the control unit 11 completes the process of step S301, the control unit 11 selects the indoor unit 300 (step S302). When the control unit 11 completes the process of step S302, the control unit 11 selects the outlet 310 (step S303). Specifically, the control unit 11 selects one unselected outlet 310 from the four outlets 310.
制御部11は、ステップS303の処理を完了すると、選択した吹出口310の風向を真横に設定する(ステップS304)。具体的には、制御部11は、選択した室内機300が備える選択した吹出口310から真横に調和空気が吹き出されるように、選択した吹出口310に対応するルーバ320の角度を調整する。制御部11は、ステップS304の処理を完了すると、選択していない吹出口310の風向を真下に設定する(ステップS305)。具体的には、制御部11は、選択した室内機300が備える選択していない全ての吹出口310から真下に調和空気が吹き出されるように、選択していない全ての吹出口310のそれぞれに対応するルーバ320の角度を調整する。
When the control unit 11 completes the process of step S303, the control unit 11 sets the wind direction of the selected outlet 310 to the side (step S304). Specifically, the control unit 11 adjusts the angle of the louver 320 corresponding to the selected outlet 310 so that the conditioned air is blown right beside the selected outlet 310 included in the selected indoor unit 300. When the process of step S304 is completed, the control unit 11 sets the wind direction of the unselected outlet 310 directly below (step S305). Specifically, the control unit 11 is provided at each of the unselected outlets 310 so that the conditioned air is blown directly below from all the unselected outlets 310 of the selected indoor unit 300. Adjust the angle of the corresponding louver 320.
制御部11は、ステップS305の処理を完了すると、調和空気を吹き出す(ステップS306)。例えば、制御部11は、選択した室内機300が備える全ての吹出口310から調和空気が吹き出されるように、選択した室内機300を制御する。本実施の形態では、調和空気は、暖房空気である。
When the control unit 11 completes the process of step S305, the control unit 11 blows out conditioned air (step S306). For example, the control unit 11 controls the selected indoor unit 300 so that conditioned air is blown out from all the outlets 310 included in the selected indoor unit 300. In this embodiment, the conditioned air is heating air.
制御部11は、ステップS306の処理を完了すると、天井面の赤外線画像を取得する(ステップS307)。制御部11は、ステップS201と同様の処理により、赤外線センサ210から天井面の赤外線画像を取得する。制御部11は、ステップS307の処理を完了すると、温度変化領域を特定する(ステップS308)。この温度変化領域は、ステップS301で取得された赤外線画像とステップS307で取得された赤外線画像とで、温度の変化により画像が変化した領域である。
When the control unit 11 completes the process of step S306, the control unit 11 acquires an infrared image of the ceiling surface (step S307). The control unit 11 acquires an infrared image of the ceiling surface from the infrared sensor 210 by the same processing as in step S201. When the control unit 11 completes the process of step S307, the control unit 11 identifies the temperature change region (step S308). This temperature change region is a region in which the infrared image acquired in step S301 and the infrared image acquired in step S307 change the image due to the change in temperature.
図10に、室内機300Aが選択され、吹出口310Aが選択されたときにステップS307で取得された赤外線画像である画像720を示す。画像720では、選択された室内機300Aが備える選択された吹出口310Aに対応する領域が、周囲に比べて高い温度を有する領域として観測される。より詳細には、画像720では、室内機300Aが備える吹出口310Aの外側の領域である領域330Aが、周囲に比べて高い温度を有する領域として観測される。この理由は、室内機300Aが備える吹出口310Aからは真横に暖房空気が吹き出され、室内機300Aが備える吹出口310Aの外側の部材の温度が上昇するためである。
FIG. 10 shows an image 720 which is an infrared image acquired in step S307 when the indoor unit 300A is selected and the outlet 310A is selected. In image 720, the region corresponding to the selected outlet 310A included in the selected indoor unit 300A is observed as a region having a higher temperature than the surroundings. More specifically, in the image 720, the region 330A, which is the region outside the outlet 310A included in the indoor unit 300A, is observed as a region having a higher temperature than the surroundings. The reason for this is that the heating air is blown out from the outlet 310A of the indoor unit 300A right beside, and the temperature of the member outside the outlet 310A of the indoor unit 300A rises.
これに対して、画像720では、室内機300Aが備える吹出口310B、吹出口310C及び吹出口310Dのそれぞれに対応する領域は、周囲に比べて高い温度を有する領域として観測されない。この理由は、室内機300Aが備える吹出口310B、吹出口310C及び吹出口310Dのそれぞれからは真下に暖房空気が吹き出され、室内機300Aが備える吹出口310B、吹出口310C及び吹出口310Dのそれぞれの周囲の部材の温度はあまり上昇しないためである。
On the other hand, in the image 720, the region corresponding to each of the outlet 310B, the outlet 310C and the outlet 310D included in the indoor unit 300A is not observed as a region having a higher temperature than the surroundings. The reason for this is that the heating air is blown directly below from each of the outlet 310B, the outlet 310C and the outlet 310D provided in the indoor unit 300A, and the outlet 310B, the outlet 310C and the outlet 310D provided in the indoor unit 300A, respectively. This is because the temperature of the surrounding members does not rise so much.
制御部11は、ステップS308の処理を完了すると、選択した吹出口310の相対位置を推定する(ステップS309)。例えば、選択された室内機300が室内機300Aであり、選択した吹出口310が吹出口310Aである場合、画像720では、領域330Aが温度変化領域として観測される。制御部11は、画像720上において領域330Aが観測された領域を、室内機300Aが備える吹出口310Aが設置された領域として特定する。
When the control unit 11 completes the process of step S308, the control unit 11 estimates the relative position of the selected outlet 310 (step S309). For example, when the selected indoor unit 300 is the indoor unit 300A and the selected outlet 310 is the outlet 310A, the region 330A is observed as a temperature change region in the image 720. The control unit 11 identifies the region where the region 330A is observed on the image 720 as the region where the outlet 310A included in the indoor unit 300A is installed.
制御部11は、ステップS309の処理を完了すると、選択した吹出口310の設置位置を推定する(ステップS310)。具体的には、制御部11は、ステップS102で受け付けた赤外線センサ210の設置位置と、ステップS309で推定した選択した吹出口310の相対位置とに基づいて、室内における選択した吹出口310の設置位置を推定する。
When the control unit 11 completes the process of step S309, the control unit 11 estimates the installation position of the selected outlet 310 (step S310). Specifically, the control unit 11 installs the selected outlet 310 in the room based on the installation position of the infrared sensor 210 received in step S102 and the relative position of the selected outlet 310 estimated in step S309. Estimate the position.
制御部11は、ステップS310の処理を完了すると、未選択の吹出口310があるか否かを判別する(ステップS311)。制御部11は、未選択の吹出口310があると判別すると(ステップS311:YES)、ステップS303に処理を戻す。制御部11は、未選択の吹出口310がないと判別すると(ステップS311:NO)、未選択の室内機300があるか否かを判別する(ステップS312)。制御部11は、未選択の室内機300があると判別すると(ステップS312:YES)、ステップS302に処理を戻す。制御部11は、未選択の室内機300がないと判別すると(ステップS312:NO)、吹出口位置推定処理を完了する。
When the processing of step S310 is completed, the control unit 11 determines whether or not there is an unselected outlet 310 (step S311). When the control unit 11 determines that there is an unselected outlet 310 (step S311: YES), the control unit 11 returns the process to step S303. When the control unit 11 determines that there is no unselected outlet 310 (step S311: NO), the control unit 11 determines whether or not there is an unselected indoor unit 300 (step S312). When the control unit 11 determines that there is an unselected indoor unit 300 (step S312: YES), the control unit 11 returns the process to step S302. When the control unit 11 determines that there is no unselected indoor unit 300 (step S312: NO), the control unit 11 completes the outlet position estimation process.
制御部11は、位置検出の開始指示がないと判別した場合(ステップS101:NO)、又は、ステップS104の吹出口位置推定処理を完了した場合、熱分布画像の表示指示があるか否かを判別する(ステップS105)。例えば、制御部11は、操作受付部14が、ユーザから熱分布画像の表示を指示する表示指示操作を受け付けたか否かを判別する。又は、制御部11は、熱分布画像の表示を指示する表示指示情報を端末装置500から受信したか否かを判別する。
When the control unit 11 determines that there is no position detection start instruction (step S101: NO), or when the outlet position estimation process in step S104 is completed, whether or not there is a heat distribution image display instruction. Determination (step S105). For example, the control unit 11 determines whether or not the operation reception unit 14 has received a display instruction operation instructing the display of the heat distribution image from the user. Alternatively, the control unit 11 determines whether or not the display instruction information instructing the display of the heat distribution image has been received from the terminal device 500.
制御部11は、熱分布画像の表示指示があると判別すると(ステップS105:YES)、熱分布画像を表示する(ステップS106)。例えば、制御部11は、表示部13を制御して、熱分布画像を表示する。又は、制御部11は、熱分布画像を示す画像情報を端末装置500に送信し、端末装置500に熱分布画像を表示させる。この熱分布画像は、室内の熱分布と室内機300の位置とを示す画像である。例えば、熱分布画像は、赤外線センサ210が取得した赤外線画像、又は、赤外線センサ220が取得した赤外線画像に、室内機300の位置を示す画像を合成した画像である。
When the control unit 11 determines that there is an instruction to display the heat distribution image (step S105: YES), the control unit 11 displays the heat distribution image (step S106). For example, the control unit 11 controls the display unit 13 to display a heat distribution image. Alternatively, the control unit 11 transmits image information indicating the heat distribution image to the terminal device 500, and causes the terminal device 500 to display the heat distribution image. This heat distribution image is an image showing the heat distribution in the room and the position of the indoor unit 300. For example, the heat distribution image is an image obtained by synthesizing an infrared image acquired by the infrared sensor 210 or an infrared image acquired by the infrared sensor 220 with an image showing the position of the indoor unit 300.
図11に、熱分布画像である画像730を示す。画像730は、赤外線センサ220が取得した赤外線画像に、室内機300を示すアイコン画像と、吹出口310の名称を示す文字列画像とを合成した画像である。空調機位置推定処理により推定された室内機300の設置位置に基づいて、画像730上におけるアイコン画像の位置が決定される。また、吹出口位置推定処理により推定された吹出口310の設置位置に基づいて、画像730上における文字列画像の位置が決定される。なお、室内機A、室内機B、室内機C及び室内機Dは、それぞれ、室内機300A、室内機300B、室内機300C及び室内機300Dの名称である。また、吹出口A、吹出口B、吹出口C及び吹出口Dは、それぞれ、吹出口310A、吹出口310B、吹出口310C及び吹出口310Dの名称である。
FIG. 11 shows an image 730 which is a heat distribution image. The image 730 is an image obtained by synthesizing an icon image showing the indoor unit 300 and a character string image showing the name of the outlet 310 with the infrared image acquired by the infrared sensor 220. The position of the icon image on the image 730 is determined based on the installation position of the indoor unit 300 estimated by the air conditioner position estimation process. Further, the position of the character string image on the image 730 is determined based on the installation position of the outlet 310 estimated by the outlet position estimation process. The indoor unit A, the indoor unit B, the indoor unit C, and the indoor unit D are the names of the indoor unit 300A, the indoor unit 300B, the indoor unit 300C, and the indoor unit 300D, respectively. Further, the outlet A, the outlet B, the outlet C, and the outlet D are the names of the outlet 310A, the outlet 310B, the outlet 310C, and the outlet 310D, respectively.
画像730には、領域731と領域732と領域733とが色分けにより示されている。領域731は、領域732と領域733とに比べて、温度が低い領域である。領域732は、領域731よりも温度が高く、領域733よりも温度が低い領域である。領域733は、領域731と領域732とに比べて、温度が高い領域である。画像730では、室内機300Aが領域731と領域732とに重なり、室内機300Bと室内機300Cと室内機300Dとが領域733に重なる。
In the image 730, the area 731, the area 732, and the area 733 are shown by color coding. The region 731 is a region where the temperature is lower than that of the region 732 and the region 733. The region 732 is a region having a higher temperature than the region 731 and a lower temperature than the region 733. The region 733 is a region having a higher temperature than the region 731 and the region 732.

次に、図14を参照して、空調制御装置110の機能的な構成について説明する。空調制御装置110は、機能的には、画像取得部101と、空調制御部102と、位置推定部103と、出力部104とを備える。空調制御装置110は、機能的には、角度制御部105を備えない点と、画像取得部101が第1通信部15ではなく第4通信部19を介して赤外線画像を取得する点とが、空調制御装置100と異なる。
Next, the functional configuration of the air conditioning control device 110 will be described with reference to FIG. The air conditioning control device 110 functionally includes an image acquisition unit 101, an air conditioning control unit 102, a position estimation unit 103, and an output unit 104. Functionally, the air conditioning control device 110 does not include the angle control unit 105, and the image acquisition unit 101 acquires an infrared image via the fourth communication unit 19 instead of the first communication unit 15. It is different from the air conditioning control device 100.
本実施の形態では、撮像装置200が移動したことが検知された場合、室内機300の位置を検出する処理が実行される。つまり、第4通信部19が移動通知情報を撮像装置200から受信した場合、画像取得部101が赤外線センサ210から赤外線画像を取得する処理を実行する。また、位置推定部103は、画像取得部101が取得した赤外線画像に基づいて、室内機300の相対位置を推定する。そして、出力部104は、位置推定部103が推定した室内機300の相対位置、又は、室内機300の相対位置に基づく室内機300の設置位置を示す室内機位置情報を出力する。
In the present embodiment, when it is detected that the image pickup apparatus 200 has moved, a process of detecting the position of the indoor unit 300 is executed. That is, when the fourth communication unit 19 receives the movement notification information from the image pickup device 200, the image acquisition unit 101 executes a process of acquiring an infrared image from the infrared sensor 210. Further, the position estimation unit 103 estimates the relative position of the indoor unit 300 based on the infrared image acquired by the image acquisition unit 101. Then, the output unit 104 outputs the indoor unit position information indicating the relative position of the indoor unit 300 estimated by the position estimation unit 103 or the installation position of the indoor unit 300 based on the relative position of the indoor unit 300.
本実施の形態では、画像取得部101は、赤外線センサ210の設置角度の変更を指示する角度変更指示情報を、第4通信部19を介して撮像装置200に送信する。そして、画像取得部101は、赤外線センサ210に撮像を指示する撮像指示情報を、第4通信部19を介して撮像装置200に送信する。
In the present embodiment, the image acquisition unit 101 transmits the angle change instruction information for instructing the change of the installation angle of the infrared sensor 210 to the image pickup apparatus 200 via the fourth communication unit 19. Then, the image acquisition unit 101 transmits the image pickup instruction information instructing the infrared sensor 210 to take an image to the image pickup device 200 via the fourth communication unit 19.
次に、図15を参照して、撮像装置200の機能的な構成について説明する。撮像装置200は、機能的には、撮像制御部201と、角度制御部202と、移動通知部203とを備える。これらの各機能は、ソフトウェア、ファームウェア、又は、ソフトウェアとファームウェアとの組み合わせによって実現される。ソフトウェア及びファームウェアは、プログラムとして記述され、ROM又は記憶部22に格納される。そして、CPUが、ROM又は記憶部22に記憶されたプログラムを実行することによって、これらの各機能を実現する。
Next, the functional configuration of the image pickup apparatus 200 will be described with reference to FIG. The image pickup apparatus 200 functionally includes an image pickup control unit 201, an angle control unit 202, and a movement notification unit 203. Each of these functions is realized by software, firmware, or a combination of software and firmware. The software and firmware are described as a program and stored in the ROM or the storage unit 22. Then, the CPU realizes each of these functions by executing the program stored in the ROM or the storage unit 22.
撮像制御部201は、赤外線センサ210による撮像を制御する。例えば、撮像制御部201は、通信部23が空調制御装置110から撮像指示情報を受信した場合、赤外線センサ210に撮像を指示し、赤外線センサ210から赤外線画像を取得する。撮像制御部201は、通信部23を介して、赤外線画像を空調制御装置110に送信する。
The image pickup control unit 201 controls the image pickup by the infrared sensor 210. For example, when the communication unit 23 receives the image pickup instruction information from the air conditioning control device 110, the image pickup control unit 201 instructs the infrared sensor 210 to take an image and acquires an infrared image from the infrared sensor 210. The image pickup control unit 201 transmits an infrared image to the air conditioning control device 110 via the communication unit 23.
角度制御部202は、角度調整部24の動作を制御する。例えば、角度制御部202は、通信部23が空調制御装置110から角度変更指示情報を受信した場合、角度調整部24を制御して、赤外線センサ210の設置角度を変更する。
The angle control unit 202 controls the operation of the angle adjustment unit 24. For example, when the communication unit 23 receives the angle change instruction information from the air conditioning control device 110, the angle control unit 202 controls the angle adjustment unit 24 to change the installation angle of the infrared sensor 210.
移動通知部203は、撮像装置200が移動したことを通知する。例えば、移動通知部203は、移動検知部25により撮像装置200の移動が検知された場合、撮像装置200が移動したことを通知する移動通知情報を、通信部23を介して、空調制御装置110に送信する。移動通知情報は、撮像装置200の移動量、撮像装置200の移動方向、撮像装置200の向き等を示す情報を含んでいてもよい。
The movement notification unit 203 notifies that the image pickup apparatus 200 has moved. For example, when the movement detection unit 25 detects the movement of the image pickup device 200, the movement notification unit 203 sends the movement notification information notifying that the image pickup device 200 has moved via the communication unit 23 to the air conditioning control device 110. Send to. The movement notification information may include information indicating the movement amount of the image pickup device 200, the movement direction of the image pickup device 200, the direction of the image pickup device 200, and the like.
空調制御装置110が実行する空調制御処理は、空調制御装置110が無線通信で赤外線センサ210から赤外線画像を取得する点と、撮像装置200の移動が検知されたときに位置検出指示があったと判別される点とを除き、空調制御装置100が実行する空調制御処理と同様である。
The air-conditioning control process executed by the air-conditioning control device 110 determines that the air-conditioning control device 110 acquires an infrared image from the infrared sensor 210 by wireless communication and that a position detection instruction is given when the movement of the image pickup device 200 is detected. It is the same as the air conditioning control process executed by the air conditioning control device 100 except that the point is.
本実施の形態では、空調制御装置110と赤外線センサ210とが無線で通信する。従って、本実施の形態によれば、赤外線センサ210の設置場所の自由度が高い。例えば、空調制御装置110の設置位置が天井610の撮像に適さない設置位置である場合、空調制御装置110に赤外線センサ210を内蔵すると、天井610の赤外線画像を取得することが困難である。本実施の形態に係る空調システム1100では、空調制御装置110と赤外線センサ210とが無線で通信するため、赤外線センサ210の設置場所を自由に変更することができる。
In this embodiment, the air conditioning control device 110 and the infrared sensor 210 communicate wirelessly. Therefore, according to the present embodiment, the degree of freedom in the installation location of the infrared sensor 210 is high. For example, when the installation position of the air conditioning control device 110 is an installation position unsuitable for imaging the ceiling 610, it is difficult to acquire an infrared image of the ceiling 610 if the infrared sensor 210 is built in the air conditioning control device 110. In the air conditioning system 1100 according to the present embodiment, since the air conditioning control device 110 and the infrared sensor 210 communicate wirelessly, the installation location of the infrared sensor 210 can be freely changed.
また、本実施の形態では、撮像装置200の移動が検知されたときに、室内機300の位置検出が自動で開始される。従って、本実施の形態によれば、撮像装置200が移動する毎に、空調制御装置110に室内機300の位置検出を実行させたい場合において、撮像装置200が移動する毎に、ユーザが空調制御装置110に位置検出指示をする必要がなく、ユーザ負担の軽減が期待できる。
Further, in the present embodiment, when the movement of the image pickup apparatus 200 is detected, the position detection of the indoor unit 300 is automatically started. Therefore, according to the present embodiment, when the air conditioning control device 110 wants to execute the position detection of the indoor unit 300 every time the image pickup device 200 moves, the user controls the air conditioning every time the image pickup device 200 moves. It is not necessary to give a position detection instruction to the device 110, which can be expected to reduce the burden on the user.
例えば、施工業者が室内に室内機300を設置した際、天井610に設置された複数の室内機300の位置関係を検出及び記録したいことがある。つまり、施工業者は、室内機300の配置マップを作成したいことがある。ここで、例えば、室内機300が設置される部屋が広い場合、赤外線センサ210が天井610に設置された全ての室内機300を一度に撮像できないことがある。この場合、赤外線センサ210を移動させながら空調制御装置110に室内機300の位置検出を実行させ、取得された複数の赤外線画像に基づいて、全ての室内機300の位置を特定する方法が考えられる。この場合において、赤外線センサ210が移動する毎に、室内機300の位置検出が自動で実行されると、ユーザの手間が少なく便利である。
For example, when a contractor installs an indoor unit 300 indoors, he / she may want to detect and record the positional relationship of a plurality of indoor units 300 installed on the ceiling 610. That is, the contractor may want to create a layout map of the indoor unit 300. Here, for example, when the room in which the indoor unit 300 is installed is large, the infrared sensor 210 may not be able to image all the indoor units 300 installed in the ceiling 610 at once. In this case, a method is conceivable in which the air conditioning control device 110 is made to detect the position of the indoor unit 300 while moving the infrared sensor 210, and the positions of all the indoor units 300 are specified based on the acquired plurality of infrared images. .. In this case, if the position detection of the indoor unit 300 is automatically executed every time the infrared sensor 210 moves, it is convenient because the user has less trouble.
