The configurations of the control unit 31, storage unit 32, display unit 33, operation reception unit 34, and first communication unit 35 are basically the control unit 11, storage unit 12, display unit 13, operation reception unit 14, and first communication unit 35, respectively. The configuration is similar to that of the communication unit 15. System controller 300 is an example of an air conditioner.

Next, the functions of the air conditioning system 1000 will be described with reference to FIG. 2. Functionally, the outdoor unit 100 includes a data recording section 101 and a data transmitting section 102. Indoor unit 200 functionally includes a data recording section 201 and a data transmitting section 202. Functionally, the system controller 300 includes an abnormality diagnosis section 301 and an abnormality notification section 302.
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12,22,32に格納される。そして、CPUが、ROM又は記憶部12,22,32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。
Each of these functions is realized by software, firmware, or a combination of software and firmware. Software and firmware are written as programs and stored in ROM or storage units 12, 22, and 32. Each of these functions is realized by the CPU executing programs stored in the ROM or the storage units 12, 22, and 32.
データ記録部101は、センサ16が出力したセンサデータを記憶部12に記録する。データ記録部101がセンサデータの記録を開始するタイミング、データ記録部101がセンサデータを記録する時間の長さ等は、適宜、調整することができる。例えば、データ記録部101は、常時、センサデータを記録してもよいし、定期的に予め定められた時間分のセンサデータを記録してもよい。
The data recording unit 101 records sensor data output by the sensor 16 in the storage unit 12. The timing at which the data recording unit 101 starts recording sensor data, the length of time that the data recording unit 101 records sensor data, etc. can be adjusted as appropriate. For example, the data recording unit 101 may record sensor data all the time, or may periodically record sensor data for a predetermined period of time.
また、データ記録部101は、室外機100の異常が疑われる場合に、センサデータの記録を開始してもよい。例えば、データ記録部101は、室外機100の空調能力が低下した場合に、センサデータの記録を開始してもよい。また、データ記録部101は、室外機100に設置された、センサ16以外のセンサのセンサ値が基準値から外れた場合に、センサデータの記録を開始してもよい。なお、センサ16によるセンサデータの出力は、データ記録部101により制御されてもよいし、データ記録部101により制御されなくてもよい。
Furthermore, the data recording unit 101 may start recording sensor data when an abnormality in the outdoor unit 100 is suspected. For example, the data recording unit 101 may start recording sensor data when the air conditioning capacity of the outdoor unit 100 decreases. Further, the data recording unit 101 may start recording sensor data when the sensor value of a sensor other than the sensor 16 installed in the outdoor unit 100 deviates from a reference value. Note that the output of sensor data by the sensor 16 may or may not be controlled by the data recording section 101.
データ送信部102は、センサ16が出力したセンサデータをシステムコントローラ300に送信する。具体的には、データ送信部102は、第1通信部15を制御して、記憶部12に記憶された画像データ又は音声データを、空気調和ネットワーク910を介してシステムコントローラ300に送信する。
The data transmission unit 102 transmits sensor data output by the sensor 16 to the system controller 300. Specifically, the data transmission unit 102 controls the first communication unit 15 to transmit the image data or audio data stored in the storage unit 12 to the system controller 300 via the air conditioning network 910.
データ記録部201は、センサ26が出力したセンサデータを記憶部22に記録する。データ記録部201の機能は、基本的に、データ記録部101の機能と同様である。従って、データ記録部201がセンサデータの記録を開始するタイミング、データ記録部201がセンサデータを記録する時間の長さ等は、適宜、調整することができる。また、センサ26によるセンサデータの出力は、データ記録部201により制御されてもよいし、データ記録部201により制御されなくてもよい。
The data recording unit 201 records sensor data output by the sensor 26 in the storage unit 22. The functions of the data recording section 201 are basically the same as those of the data recording section 101. Therefore, the timing at which the data recording section 201 starts recording sensor data, the length of time during which the data recording section 201 records sensor data, etc. can be adjusted as appropriate. Further, the output of sensor data by the sensor 26 may be controlled by the data recording section 201 or may not be controlled by the data recording section 201.
データ送信部202は、センサ26が出力したセンサデータをシステムコントローラ300に送信する。具体的には、データ送信部202は、第1通信部25を制御して、記憶部22に記憶された画像データ又は音声データを、空気調和ネットワーク910を介してシステムコントローラ300に送信する。
The data transmission unit 202 transmits sensor data output by the sensor 26 to the system controller 300. Specifically, the data transmission section 202 controls the first communication section 25 to transmit the image data or audio data stored in the storage section 22 to the system controller 300 via the air conditioning network 910.
異常診断部301は、空気調和ネットワーク910を介してセンサ16から取得したセンサデータに基づいて、室外機100の異常を診断する。室外機100の異常を診断することは、例えば、室外機100に異常があるか否かを判別し、室外機100の異常の程度を判別することである。室外機100の異常としては、室外機100が備える各部の故障、室外機100が備える各部の機能低下等がある。具体的には、室外機100の異常としては、例えば、経年劣化による圧縮機の動作不良、室外ファンの周囲の異物による室外ファンの回転不足、室外機100の周囲の障害物による圧縮機の温度異常、冷媒ガスの漏れによる冷媒ガスの不足等がある。異常診断部301が室外機100の異常を診断する手法は、適宜、調整することができる。
The abnormality diagnosis unit 301 diagnoses an abnormality in the outdoor unit 100 based on sensor data acquired from the sensor 16 via the air conditioning network 910. Diagnosing an abnormality in the outdoor unit 100 means, for example, determining whether or not there is an abnormality in the outdoor unit 100, and determining the degree of abnormality in the outdoor unit 100. Abnormalities in the outdoor unit 100 include failure of each part of the outdoor unit 100, functional decline of each part of the outdoor unit 100, and the like. Specifically, abnormalities in the outdoor unit 100 include malfunction of the compressor due to aging, insufficient rotation of the outdoor fan due to foreign matter around the outdoor fan, and temperature of the compressor due to obstacles around the outdoor unit 100. There is an abnormality, a shortage of refrigerant gas due to a refrigerant gas leak, etc. The method by which the abnormality diagnosis unit 301 diagnoses an abnormality in the outdoor unit 100 can be adjusted as appropriate.
例えば、異常診断部301は、機械学習により得られた学習済みモデルを用いて、画像データ又は音声データから室外機100の異常を診断してもよい。この学習済みモデルは、例えば、ニューラルネットワークを用いた教師あり学習により取得される。例えば、室外機100の画像データ又は音声データと異常の有無を示すデータとを含む教師データを学習装置に供給することにより、この学習済みモデルが取得される。
For example, the abnormality diagnosis unit 301 may diagnose abnormalities in the outdoor unit 100 from image data or audio data using a learned model obtained by machine learning. This trained model is obtained, for example, by supervised learning using a neural network. For example, this trained model is obtained by supplying teacher data including image data or audio data of the outdoor unit 100 and data indicating the presence or absence of an abnormality to the learning device.
又は、異常診断部301は、正常時の画像データと異常時の画像データとセンサ16が取得した画像データとを比較し、センサ16が取得した画像データを正常時の画像データと異常時の画像データとの何れかに分類してもよい。画像データの比較においては、例えば、画像データから抽出される特徴量を比較することが好適である。
Alternatively, the abnormality diagnosis unit 301 compares the image data of the normal state, the image data of the abnormal state, and the image data acquired by the sensor 16, and divides the image data acquired by the sensor 16 into the image data of the normal state and the image of the abnormal state. It may be classified into either data. In comparing image data, for example, it is preferable to compare feature amounts extracted from the image data.
また、異常診断部301は、空気調和ネットワーク910を介してセンサ26から取得したセンサデータに基づいて、室内機200の異常を診断する。室内機200の異常を診断することは、例えば、室内機200に異常があるか否かを判別し、室内機200の異常の程度を判別することである。室内機200の異常としては、室内機200が備える各部の故障、室内機200が備える各部の機能低下等がある。
Furthermore, the abnormality diagnosis unit 301 diagnoses abnormalities in the indoor unit 200 based on sensor data acquired from the sensor 26 via the air conditioning network 910. Diagnosing an abnormality in the indoor unit 200 means, for example, determining whether or not there is an abnormality in the indoor unit 200, and determining the degree of abnormality in the indoor unit 200. Abnormalities in the indoor unit 200 include failure of each part of the indoor unit 200, functional decline of each part of the indoor unit 200, and the like.
具体的には、室内機200の異常としては、ドレンホースの目詰まりによる水漏れ、フィルタの目詰まりによる風量不足、冷媒ガスの漏れによる冷媒ガスの不足等がある。異常診断部301が室内機200の異常を診断する手法は、適宜、調整することができる。例えば、異常診断部301は、機械学習により得られた学習済みモデルを用いて、画像データ又は音声データから室内機200の異常を診断してもよい。
Specifically, abnormalities in the indoor unit 200 include water leakage due to a clogged drain hose, insufficient air volume due to a clogged filter, and shortage of refrigerant gas due to leakage of refrigerant gas. The method by which the abnormality diagnosis section 301 diagnoses an abnormality in the indoor unit 200 can be adjusted as appropriate. For example, the abnormality diagnosis unit 301 may diagnose abnormalities in the indoor unit 200 from image data or audio data using a learned model obtained by machine learning.
また、異常診断部301は、室外機100に故障又は機能低下の前兆がある場合、室外機100が異常であると判別してもよい。例えば、異常診断部301は、センサ16から取得したセンサデータが、故障直前の室外機100から取得されたセンサデータと近似する場合、室外機100に故障の前兆があると見做し、室外機100が異常であると判別してもよい。同様に、異常診断部301は、室内機200に故障又は機能低下の前兆がある場合、室内機200が異常であると判別してもよい。
Further, the abnormality diagnosis unit 301 may determine that the outdoor unit 100 is abnormal if there is a sign of failure or functional decline in the outdoor unit 100. For example, if the sensor data acquired from the sensor 16 is similar to the sensor data acquired from the outdoor unit 100 immediately before the failure, the abnormality diagnosis unit 301 assumes that there is a sign of failure in the outdoor unit 100, and 100 may be determined to be abnormal. Similarly, the abnormality diagnosis unit 301 may determine that the indoor unit 200 is abnormal if there is a sign of a failure or functional decline in the indoor unit 200.
なお、室外機100又は室内機200の異常を診断するためには、多大な処理負荷を要する。このため、異常を診断する異常診断部301は、処理能力の高いCPUを備える装置が実行することが好適である。本実施の形態では、室外機100と室内機200とに比べて処理能力が高いCPUを備えるシステムコントローラ300が、異常を診断する異常診断部301を備えている。異常診断部301は、異常診断手段の一例である。
Note that diagnosing an abnormality in the outdoor unit 100 or the indoor unit 200 requires a large processing load. For this reason, it is preferable that the abnormality diagnosis unit 301 that diagnoses abnormalities is executed by a device including a CPU with high processing capacity. In the present embodiment, a system controller 300 equipped with a CPU having a higher processing capacity than the outdoor unit 100 and the indoor unit 200 includes an abnormality diagnosis section 301 that diagnoses abnormalities. The abnormality diagnosis section 301 is an example of an abnormality diagnosis means.
異常通知部302は、異常診断部301が室外機100の異常を検知した場合、室外機100の異常をユーザに通知する。また、異常通知部302は、異常診断部301が室内機200の異常を検知した場合、室内機200の異常をユーザに通知する。異常通知部302が室外機100又は室内機200の異常をユーザに通知する方法は、適宜、調整することができる。例えば、異常通知部302は、画面表示、音声出力等により、ユーザに異常を通知することができる。
When the abnormality diagnosis unit 301 detects an abnormality in the outdoor unit 100, the abnormality notification unit 302 notifies the user of the abnormality in the outdoor unit 100. Furthermore, when the abnormality diagnosis section 301 detects an abnormality in the indoor unit 200, the abnormality notification unit 302 notifies the user of the abnormality in the indoor unit 200. The method by which the abnormality notification unit 302 notifies the user of an abnormality in the outdoor unit 100 or the indoor unit 200 can be adjusted as appropriate. For example, the abnormality notification unit 302 can notify the user of the abnormality through screen display, audio output, or the like.
具体的には、例えば、異常通知部302は、室外機100又は室内機200の異常に関連する情報である異常関連情報を通知する異常通知画面を表示部33に表示させることができる。異常関連情報は、例えば、異常が発生した箇所、異常の内容、異常に対する対策等を示す情報である。異常が発生した箇所は、例えば、圧縮機、室外ファン、フィルタ等である。異常の内容は、例えば、発熱、異音、振動、冷媒ガス漏れ、目詰まり等である。異常に対する対策は、例えば、カスタマーセンターへの連絡、障害物の除去、冷媒ガスの補充、フィルタの清掃等である。
Specifically, for example, the abnormality notification unit 302 can cause the display unit 33 to display an abnormality notification screen that reports abnormality-related information that is information related to an abnormality in the outdoor unit 100 or the indoor unit 200. The abnormality related information is, for example, information indicating the location where the abnormality has occurred, the details of the abnormality, countermeasures for the abnormality, and the like. The location where the abnormality has occurred is, for example, a compressor, an outdoor fan, a filter, or the like. Examples of the abnormality include heat generation, abnormal noise, vibration, refrigerant gas leak, and clogging. Countermeasures against abnormalities include, for example, contacting a customer center, removing obstacles, replenishing refrigerant gas, and cleaning filters.
また、異常通知部302は、表示部33ではなく、室外機100が備える表示部13又は室内機200が備える表示部23に、異常通知画面を表示させてもよい。この場合、異常通知部302は、第1通信部35を介して、室外機100又は室内機200に異常関連情報を送信する。また、異常通知部302は、画面表示ではなく音声出力により、ユーザに異常を通知してもよい。例えば、異常通知部302は、室外機100、室内機200、又は、システムコントローラ300が備えるスピーカに、異常関連情報を音声出力させる。異常通知部302は、異常通知手段の一例である。
Furthermore, the abnormality notification section 302 may display the abnormality notification screen on the display section 13 of the outdoor unit 100 or the display section 23 of the indoor unit 200, instead of the display section 33. In this case, the abnormality notification unit 302 transmits abnormality related information to the outdoor unit 100 or the indoor unit 200 via the first communication unit 35. Further, the abnormality notification unit 302 may notify the user of the abnormality by audio output instead of displaying the screen. For example, the abnormality notification unit 302 causes a speaker included in the outdoor unit 100, the indoor unit 200, or the system controller 300 to output abnormality-related information as a sound. The abnormality notification unit 302 is an example of an abnormality notification means.
次に、図3を参照して、室外機100が実行するデータ送信処理について説明する。データ送信処理は、例えば、室外機100の電源が投入されたことに応答して開始される。
Next, with reference to FIG. 3, the data transmission process executed by the outdoor unit 100 will be described. The data transmission process is started, for example, in response to powering on the outdoor unit 100.
まず、室外機100が備える制御部11は、データ記録のトリガが発生したか否かを判別する(ステップS101)。データ記録のトリガは、適宜、調整することができる。データ記録のトリガは、常時発生してもよいし、定期的に発生してもよいし、室外機100の異常が疑われるときに発生してもよい。
First, the control unit 11 included in the outdoor unit 100 determines whether a data recording trigger has occurred (step S101). The data recording trigger can be adjusted as appropriate. The data recording trigger may occur all the time, periodically, or when an abnormality in the outdoor unit 100 is suspected.
制御部11は、データ記録のトリガが発生したと判別すると(ステップS101:YES)、規定時間分のセンサデータを記録する(ステップS102)。例えば、制御部11は、センサ16の電源を規定時間オンし、センサ16が出力する規定時間分のセンサデータを記憶部12に記録する。例えば、センサ16がイメージセンサである場合、制御部11は、規定時間分の動画データを記憶部12に記録する。
When the control unit 11 determines that a trigger for data recording has occurred (step S101: YES), it records sensor data for a specified time (step S102). For example, the control unit 11 turns on the power of the sensor 16 for a specified period of time, and records sensor data output by the sensor 16 for the specified period in the storage unit 12 . For example, when the sensor 16 is an image sensor, the control unit 11 records video data for a specified time in the storage unit 12.
制御部11は、ステップS102の処理を完了すると、センサデータをシステムコントローラ300に送信する(ステップS103)。具体的には、制御部11は、記憶部12に記憶された規定時間分のセンサデータを、第1通信部15を介してシステムコントローラ300に送信する。制御部11は、データ記録のトリガが発生していないと判別した場合(ステップS101:NO)、又は、ステップS103の処理を完了した場合、ステップS101に処理を戻す。
After completing the process of step S102, the control unit 11 transmits the sensor data to the system controller 300 (step S103). Specifically, the control unit 11 transmits sensor data for a specified period of time stored in the storage unit 12 to the system controller 300 via the first communication unit 15. If the control unit 11 determines that a data recording trigger has not occurred (step S101: NO), or if the process of step S103 is completed, the process returns to step S101.
なお、室内機200が実行するデータ送信処理は、基本的に、室外機100が実行するデータ送信処理と同様である。つまり、室内機200が備える制御部21は、センサ26が出力したセンサデータを、第1通信部25を介してシステムコントローラ300に送信する。
Note that the data transmission process executed by the indoor unit 200 is basically the same as the data transmission process executed by the outdoor unit 100. That is, the control unit 21 included in the indoor unit 200 transmits sensor data output by the sensor 26 to the system controller 300 via the first communication unit 25.
次に、図4を参照して、システムコントローラ300が実行する異常通知処理について説明する。異常通知処理は、例えば、システムコントローラ300の電源が投入されたことに応答して開始される。
Next, with reference to FIG. 4, the abnormality notification process executed by the system controller 300 will be described. The abnormality notification process is started, for example, in response to the system controller 300 being powered on.
まず、システムコントローラ300が備える制御部31は、室外機100からセンサデータを受信したか否かを判別する(ステップS201)。制御部31は、室外機100からセンサデータを受信したと判別すると(ステップS201:YES)、室外機100の異常を診断する(ステップS202)。例えば、制御部31は、受信したセンサデータを記憶部32に記憶された学習済みモデルに入力し、学習済みモデルの出力から室外機100の異常を診断する。
First, the control unit 31 included in the system controller 300 determines whether sensor data has been received from the outdoor unit 100 (step S201). When the control unit 31 determines that sensor data has been received from the outdoor unit 100 (step S201: YES), it diagnoses an abnormality in the outdoor unit 100 (step S202). For example, the control unit 31 inputs the received sensor data to a trained model stored in the storage unit 32, and diagnoses an abnormality in the outdoor unit 100 from the output of the trained model.
制御部31は、ステップS202の処理を完了すると、室外機100が異常であるか否かを判別する(ステップS203)。制御部31は、室外機100が異常であると判別すると(ステップS203:YES)、室外機100の異常を通知する(ステップS204)。例えば、制御部31は、室外機100の異常関連情報を通知する異常通知画面を表示部33に表示させる。
After completing the process of step S202, the control unit 31 determines whether or not the outdoor unit 100 is abnormal (step S203). When the control unit 31 determines that the outdoor unit 100 is abnormal (step S203: YES), it notifies the outdoor unit 100 of the abnormality (step S204). For example, the control unit 31 causes the display unit 33 to display an abnormality notification screen that notifies information related to an abnormality of the outdoor unit 100.
制御部31は、室外機100からセンサデータを受信していないと判別した場合(ステップS201:NO)、室外機100が異常でないと判別した場合(ステップS203:NO)、又は、ステップS204の処理を完了した場合、室内機200からセンサデータを受信したか否かを判別する(ステップS205)。制御部31は、室内機200からセンサデータを受信したと判別すると(ステップS205:YES)、室内機200の異常を診断する(ステップS206)。

Next, with reference to FIG. 9, the data transmission process executed by the indoor unit 220 will be described. The data transmission process is started, for example, in response to the indoor unit 220 being powered on. Note that the data transmission process executed by outdoor unit 100 in this embodiment is similar to the data transmission process described in Embodiment 1, except that the destination of sensor data is indoor unit 220 instead of system controller 300. It is.
まず、室内機220が備える制御部21は、データ記録のトリガが発生したか否かを判別する(ステップS301)。制御部21は、データ記録のトリガが発生したと判別すると(ステップS301:YES)、規定時間分のセンサデータを記録する(ステップS302)。制御部21は、ステップS302の処理を完了すると、室内機220のセンサデータをサーバ500に送信する(ステップS303)。具体的には、制御部21は、記憶部22に記憶された規定時間分のセンサデータを、第2通信部27を介してサーバ500に送信する。
First, the control unit 21 included in the indoor unit 220 determines whether a trigger for data recording has occurred (step S301). When the control unit 21 determines that a trigger for data recording has occurred (step S301: YES), it records sensor data for a specified time (step S302). After completing the process of step S302, the control unit 21 transmits sensor data of the indoor unit 220 to the server 500 (step S303). Specifically, the control unit 21 transmits sensor data for a specified time stored in the storage unit 22 to the server 500 via the second communication unit 27.
制御部21は、データ記録のトリガが発生していないと判別した場合(ステップS301:NO)、又は、ステップS303の処理を完了した場合、室外機100からセンサデータを受信したか否かを判別する(ステップS304)。制御部21は、室外機100からセンサデータを受信したと判別すると(ステップS304:YES)、室外機100のセンサデータをサーバ500に送信する(ステップS305)。具体的には、制御部21は、室外機100から受信した規定時間分のセンサデータを、第2通信部27を介してサーバ500に送信する。

If the control unit 21 determines that sensor data has not been received from the outdoor unit 100 (step S304: NO), or if the process of step S305 is completed, the process returns to step S301.
次に、図10を参照して、サーバ500が実行する異常通知処理について説明する。異常通知処理は、例えば、サーバ500の電源が投入されたことに応答して開始される。
Next, with reference to FIG. 10, the abnormality notification process executed by the server 500 will be described. The abnormality notification process is started, for example, in response to the server 500 being powered on.
まず、サーバ500が備える制御部51は、室内機220からセンサデータを受信したか否かを判別する(ステップS401)。制御部51は、室内機220からセンサデータを受信したと判別すると(ステップS401:YES)、受信したセンサデータが室外機100のセンサデータであるか否かを判別する(ステップS402)。
First, the control unit 51 included in the server 500 determines whether sensor data has been received from the indoor unit 220 (step S401). When the control unit 51 determines that sensor data has been received from the indoor unit 220 (step S401: YES), the control unit 51 determines whether the received sensor data is sensor data of the outdoor unit 100 (step S402).
制御部51は、受信したセンサデータが室外機100のセンサデータであると判別すると(ステップS402:YES)、室外機100の異常を診断する(ステップS403)。例えば、制御部51は、受信したセンサデータを記憶部52に記憶された学習済みモデルに入力し、学習済みモデルの出力から室外機100の異常を診断する。
When the control unit 51 determines that the received sensor data is sensor data of the outdoor unit 100 (step S402: YES), it diagnoses an abnormality in the outdoor unit 100 (step S403). For example, the control unit 51 inputs the received sensor data to a trained model stored in the storage unit 52, and diagnoses an abnormality in the outdoor unit 100 from the output of the trained model.
制御部51は、ステップS403の処理を完了すると、室外機100が異常であるか否かを判別する(ステップS404)。制御部51は、室外機100が異常であると判別すると(ステップS404:YES)、室外機100の異常を通知する(ステップS405)。例えば、制御部51は、室外機100の異常関連情報を、第2通信部57を介して端末装置600に送信する。端末装置600は、サーバ500から室外機100の異常関連情報を受信すると、室外機100の異常を通知する異常通知画面を表示部63に表示する。
After completing the process in step S403, the control unit 51 determines whether or not the outdoor unit 100 is abnormal (step S404). When the control unit 51 determines that the outdoor unit 100 is abnormal (step S404: YES), it notifies the outdoor unit 100 of the abnormality (step S405). For example, the control unit 51 transmits abnormality related information of the outdoor unit 100 to the terminal device 600 via the second communication unit 57. When the terminal device 600 receives the abnormality related information of the outdoor unit 100 from the server 500, it displays an abnormality notification screen on the display unit 63 that notifies the abnormality of the outdoor unit 100.
制御部51は、受信したセンサデータが室外機100のセンサデータでないと判別すると(ステップS402:NO)、室内機220の異常を診断する(ステップS406)。例えば、制御部51は、受信したセンサデータを記憶部52に記憶された学習済みモデルに入力し、学習済みモデルの出力から室内機220の異常を診断する。
When the control unit 51 determines that the received sensor data is not sensor data of the outdoor unit 100 (step S402: NO), it diagnoses an abnormality in the indoor unit 220 (step S406). For example, the control unit 51 inputs the received sensor data to a trained model stored in the storage unit 52, and diagnoses an abnormality in the indoor unit 220 from the output of the trained model.
制御部51は、ステップS406の処理を完了すると、室内機220が異常であるか否かを判別する(ステップS407)。制御部51は、室内機220が異常であると判別すると(ステップS407:YES)、室内機220の異常を通知する(ステップS408)。例えば、制御部51は、室内機220の異常関連情報を、第2通信部57を介して端末装置600に送信する。端末装置600は、サーバ500から室内機220の異常関連情報を受信すると、室内機220の異常を通知する異常通知画面を表示部63に表示する。
After completing the process of step S406, the control unit 51 determines whether or not the indoor unit 220 is abnormal (step S407). When the control unit 51 determines that the indoor unit 220 is abnormal (step S407: YES), it notifies the indoor unit 220 of the abnormality (step S408). For example, the control unit 51 transmits abnormality related information about the indoor unit 220 to the terminal device 600 via the second communication unit 57. When the terminal device 600 receives the abnormality related information of the indoor unit 220 from the server 500, it displays an abnormality notification screen on the display unit 63 that notifies the abnormality of the indoor unit 220.
制御部51は、室内機220からセンサデータを受信していないと判別した場合(ステップS401:NO)、室外機100が異常でないと判別した場合(ステップS404:NO)、ステップS405の処理を完了した場合、室内機220が異常でないと判別した場合(ステップS407:NO)、又は、ステップS408の処理を完了した場合、ステップS401に処理を戻す。
If the control unit 51 determines that sensor data has not been received from the indoor unit 220 (step S401: NO), or if it determines that the outdoor unit 100 is not abnormal (step S404: NO), it completes the process of step S405. In this case, if it is determined that the indoor unit 220 is not abnormal (step S407: NO), or if the process in step S408 is completed, the process returns to step S401.

実施の形態1では、室外機100に設置されるセンサ16の個数が1つであり、室内機200に設置されるセンサ26の個数が1つである例について説明した。室外機100に設置されるセンサ16の個数が2つ以上でもよい。同様に、室内機200に設置されるセンサ26の個数が2つ以上でもよい。
In the first embodiment, an example has been described in which the number of sensors 16 installed in the outdoor unit 100 is one, and the number of sensors 26 installed in the indoor unit 200 is one. The number of sensors 16 installed in the outdoor unit 100 may be two or more. Similarly, the number of sensors 26 installed in the indoor unit 200 may be two or more.
実施の形態5では、室外機140と室内機240とシステムコントローラ340との3つの装置により、異常診断に関する処理を分担する例について説明した。2つの装置により、異常診断に関する処理が分散されてもよい。例えば、室外機140がパラメータAとパラメータBとを生成する処理を実行し、システムコントローラ340がパラメータAとパラメータBとから室外機140の異常を診断する処理を実行してもよい。また、3つ以上のセンサデータから3つ以上のパラメータが生成され、3つ以上のパラメータから異常が診断されてもよい。この場合、各空気調和装置の処理能力に応じて、各パラメータを生成する処理と、各パラメータから異常を診断する処理とが各空気調和装置に割り当てられることが好適である。
In Embodiment 5, an example was described in which the processing related to abnormality diagnosis is shared among three devices: the outdoor unit 140, the indoor unit 240, and the system controller 340. Processing related to abnormality diagnosis may be distributed between the two devices. For example, the outdoor unit 140 may execute a process of generating parameters A and B, and the system controller 340 may execute a process of diagnosing an abnormality in the outdoor unit 140 from the parameters A and B. Furthermore, three or more parameters may be generated from three or more sensor data, and an abnormality may be diagnosed from the three or more parameters. In this case, it is preferable that the process of generating each parameter and the process of diagnosing an abnormality from each parameter are assigned to each air conditioner according to the processing capacity of each air conditioner.
また、実施の形態5では、異常診断に関する処理が、センサデータからパラメータを生成する処理とパラメータから異常を診断する処理との2段階に分けられ、2段階に分けられた処理が複数の装置で実行される例について説明した。異常診断に関する処理を分ける手法は、この例に限定されない。例えば、異常診断に関する処理が3段階以上に分けられ、3段階以上に分けられた処理が複数の装置で実行されてもよい。また、異常診断に関する処理が負荷分散により複数の同レベルの処理に分けられ、複数の同レベルの処理が複数の装置で実行されてもよい。例えば、ある部品の異常を診断する場合、この部品の部位毎にセンサデータが取得され、複数の装置が、対応するセンサデータから対応する部位の異常を診断してもよい。
Furthermore, in the fifth embodiment, processing related to abnormality diagnosis is divided into two stages: processing for generating parameters from sensor data and processing for diagnosing abnormalities from parameters, and the processing divided into two stages is performed by multiple devices. An example of how it is executed has been explained. The method of dividing processes related to abnormality diagnosis is not limited to this example. For example, processing related to abnormality diagnosis may be divided into three or more stages, and the processing divided into three or more stages may be executed by a plurality of devices. Further, processing related to abnormality diagnosis may be divided into a plurality of processes at the same level by load distribution, and the plurality of processes at the same level may be executed by a plurality of devices. For example, when diagnosing an abnormality in a certain part, sensor data may be acquired for each part of the part, and a plurality of devices may diagnose the abnormality in the corresponding part from the corresponding sensor data.
実施の形態1では、センサ16が出力したセンサデータがデータ記録部101により記憶部12に記録され、センサ26が出力したセンサデータがデータ記録部201により記憶部22に記録される例について説明した。センサ16が出力したセンサデータが記憶部12に記録されずにシステムコントローラ300に送信されてもよい。同様に、センサ26が出力したセンサデータが記憶部22に記録されずにシステムコントローラ300に送信されてもよい。
In the first embodiment, an example has been described in which sensor data output by the sensor 16 is recorded in the storage unit 12 by the data recording unit 101, and sensor data output by the sensor 26 is recorded in the storage unit 22 by the data recording unit 201. . The sensor data output by the sensor 16 may be transmitted to the system controller 300 without being recorded in the storage unit 12. Similarly, the sensor data output by the sensor 26 may be transmitted to the system controller 300 without being recorded in the storage unit 22.
実施の形態1では、室外機100と室内機200とシステムコントローラ300とが、空気調和ネットワーク910を介して、マルチキャリア伝送方式に対応する高周波信号を用いて通信する例について説明した。室外機100と室内機200とシステムコントローラ300とが、空気調和ネットワーク910を介して、マルチキャリア伝送方式とは異なる伝送方式に対応する高周波信号を用いて通信してもよい。
In the first embodiment, an example has been described in which the outdoor unit 100, the indoor unit 200, and the system controller 300 communicate via the air conditioning network 910 using high frequency signals compatible with a multicarrier transmission method. The outdoor unit 100, the indoor unit 200, and the system controller 300 may communicate via the air conditioning network 910 using high-frequency signals that correspond to a transmission method different from the multicarrier transmission method.
