It is considered desirable that the temperature data used for air conditioning should be the temperature data obtained from a temperature sensor installed at a position close to a person existing in the target area for air conditioning. However, since the position where a person exists is usually not constant, it is desired that which temperature data to be used among the temperature data obtained from each temperature sensor can be changed according to the change in the position where the person exists.
　また、近年、様々なデータを活用して各種サービスを提供する事業者が存在する。このような事業者に住宅内に設置された各温度センサが出力する温度データを提供する場合、人が近くに存在する温度センサが出力する温度データと他の温度データとを区別できるようにすることで、データの利用価値が高まる。例えば、空気調和システムを利用する人の行動パターンを分析することが可能となり、ひいては分析結果に基づく遠隔制御を空調機に対して行えるようになる。すなわち、人が存在する位置の周辺の温度などの調整を優先的に行うよう、空調機を制御できるようになる。また、人が近くに存在する温度センサが出力する温度データの有無を確認することで、空気調和の対象エリア内に人が存在するか否かを遠隔地から知ることができる。 Also, in recent years, there are businesses that provide various services by utilizing various data. When providing the temperature data output by each temperature sensor installed in the house to such a business operator, it is possible to distinguish the temperature data output by the temperature sensor in the vicinity of a person from other temperature data. As a result, the utility value of the data increases. For example, it becomes possible to analyze the behavior pattern of a person who uses an air conditioning system, and by extension, remote control based on the analysis result can be performed on the air conditioner. That is, the air conditioner can be controlled so as to preferentially adjust the temperature around the position where a person exists. In addition, by confirming the presence or absence of temperature data output by a temperature sensor in which a person exists nearby, it is possible to know from a remote location whether or not a person exists in the target area of air conditioning.
　本発明は、上記に鑑みてなされたものであって、複数の温度センサのそれぞれから得られる温度データのうち、人が近くに存在する温度センサから得られる温度データを特定することが可能なデータ収集装置を得ることを目的とする。 The present invention has been made in view of the above, and among the temperature data obtained from each of the plurality of temperature sensors, data capable of specifying the temperature data obtained from the temperature sensor in which a person is nearby. The purpose is to obtain a collecting device.
　上述した課題を解決し、目的を達成するために、本発明にかかるデータ収集装置は、空調機が空気調和を行う空間内に設置された複数の温度センサのそれぞれから温度データを取得するデータ取得部と、空調機で検出された温度に基づいて空調機の動作状態を検知する状態検知部と、データ取得部が取得した温度データと空調機の動作状態とを解析して、人が発する熱の影響を受ける温度を検出する温度センサである代表センサを特定するデータ解析部と、を備える。 In order to solve the above-mentioned problems and achieve the object, the data collecting device according to the present invention acquires temperature data from each of a plurality of temperature sensors installed in a space where an air conditioner performs air conditioning. The heat generated by a person by analyzing the temperature data acquired by the data acquisition unit and the operating state of the air conditioner, the state detection unit that detects the operating state of the air conditioner based on the temperature detected by the air conditioner, and the data acquisition unit. It is provided with a data analysis unit that identifies a representative sensor, which is a temperature sensor that detects the temperature affected by the above.

The present invention is not limited to this embodiment.
実施の形態１．
　図１は、実施の形態１にかかるデータ収集装置を適用して実現されるデータ収集システムの一例を示す図である。 Embodiment 1.
FIG. 1 is a diagram showing an example of a data collection system realized by applying the data collection device according to the first embodiment.
　本実施の形態にかかるデータ収集システム２００は、データ収集装置１と、空調機２と、複数の温度センサ３とを含んで構成される。図１では温度センサ３を３台としているが、２台または４台以上であってもよい。 The data collection system 200 according to the present embodiment includes a data collection device 1, an air conditioner 2, and a plurality of temperature sensors 3. In FIG. 1, the number of temperature sensors 3 is three, but two or four or more may be used.
　データ収集装置１は、空調機２および各温度センサ３と無線または有線で接続され、空調機２および各温度センサ３からデータを収集する。図１に示すように、本実施の形態ではデータ収集装置１と空調機２とが有線で接続され、データ収集装置１と各温度センサ３とが無線で接続される。なお、接続形態は図１に示すものに限定されない。データ収集装置１と空調機２とが無線で接続されてもよいし、データ収集装置１と各温度センサ３とが有線で接続されてもよい。また、データ収集装置１と一部の温度センサ３とが無線で接続され、データ収集装置１と残りの温度センサ３とが有線で接続されてもよい。また、データ収集装置１は部屋５に存在する必要は無く、部屋５の外部に存在する形態であってもよい。 The data collecting device 1 is wirelessly or wiredly connected to the air conditioner 2 and each temperature sensor 3, and collects data from the air conditioner 2 and each temperature sensor 3. As shown in FIG. 1, in the present embodiment, the data collection device 1 and the air conditioner 2 are connected by wire, and the data collection device 1 and each temperature sensor 3 are wirelessly connected. The connection form is not limited to that shown in FIG. The data collection device 1 and the air conditioner 2 may be connected wirelessly, or the data collection device 1 and each temperature sensor 3 may be connected by wire. Further, the data collection device 1 and a part of the temperature sensors 3 may be wirelessly connected, and the data collection device 1 and the remaining temperature sensors 3 may be connected by wire. Further, the data collecting device 1 does not have to exist in the room 5, and may be in a form existing outside the room 5.
　また、データ収集装置１は、インターネットなどの外部ネットワーク９に接続され、外部ネットワーク９を介して他の装置と通信することができる。図１では、データ収集装置１が通信する他の装置の一例として、データ収集装置１が収集したデータを必要とするデータ利用者（図示せず）が有するデータ利用者端末８を記載している。 Further, the data collection device 1 is connected to an external network 9 such as the Internet, and can communicate with other devices via the external network 9. In FIG. 1, as an example of another device with which the data collecting device 1 communicates, a data user terminal 8 owned by a data user (not shown) who needs the data collected by the data collecting device 1 is shown. ..
　空調機２は、部屋５の温度がユーザにより設定された温度（以下、設定温度とする）に近づくよう、空気調和を行う。例えば、冷房運転では、空調機２は、部屋５の温度が設定温度よりも高く、かつ部屋５の温度と設定温度との差が第１のしきい値以上の場合、冷房を行い、部屋５の温度が設定温度よりも低く、かつ部屋５の温度と設定温度との差が第２のしきい値以上の場合、冷房を停止する。なお、部屋５は、空調機２が空気調和を行う空間である。また、空調機２は、温度センサ２１を備える。温度センサ２１は、例えば、空調機２の送風口から部屋５へ送り出される空気の温度を検出する。なお、図１では空調機２を１台としているが、２台以上であっても構わない。 The air conditioner 2 performs air conditioning so that the temperature of the room 5 approaches the temperature set by the user (hereinafter referred to as the set temperature). For example, in the cooling operation, the air conditioner 2 cools the room 5 when the temperature of the room 5 is higher than the set temperature and the difference between the temperature of the room 5 and the set temperature is equal to or larger than the first threshold value. When the temperature of the room 5 is lower than the set temperature and the difference between the temperature of the room 5 and the set temperature is equal to or larger than the second threshold value, the cooling is stopped. The room 5 is a space in which the air conditioner 2 harmonizes the air. Further, the air conditioner 2 includes a temperature sensor 21. The temperature sensor 21 detects, for example, the temperature of the air sent from the air outlet of the air conditioner 2 to the room 5. Although the number of air conditioners 2 is one in FIG. 1, two or more air conditioners may be used.
　複数の温度センサ３は、それぞれ、周囲の温度を定期的に検出して検出した温度を示す温度データを生成し、生成した温度データをデータ収集装置１へ送信する。温度データには、温度データを生成した温度センサ３の識別情報が含まれる、または、温度データには、温度データを生成した温度センサ３の識別情報が付加されているものとする。各温度センサ３は、データ収集装置１から指示を受けた場合に定期的に温度の検出および温度データの送信を行う動作を開始してもよいし、データ収集装置１との通信が可能な状態の場合に定期的に温度の検出および温度データの送信を行う動作を行うようにしてもよい。なお、各温度センサ３は、空調機２に対しても温度データを送信する。温度センサ３が空調機２へ温度データを送信するタイミングは、データ収集装置１へ温度データを送信するタイミングと同じであってもよいし、異なっていてもよい。 Each of the plurality of temperature sensors 3 periodically detects the ambient temperature, generates temperature data indicating the detected temperature, and transmits the generated temperature data to the data collection device 1. It is assumed that the temperature data includes the identification information of the temperature sensor 3 that generated the temperature data, or the identification information of the temperature sensor 3 that generated the temperature data is added to the temperature data. Each temperature sensor 3 may start an operation of periodically detecting the temperature and transmitting the temperature data when instructed by the data collecting device 1, or is in a state of being able to communicate with the data collecting device 1. In the case of, the operation of detecting the temperature and transmitting the temperature data may be performed periodically. Each temperature sensor 3 also transmits temperature data to the air conditioner 2. The timing at which the temperature sensor 3 transmits the temperature data to the air conditioner 2 may be the same as or different from the timing at which the temperature data is transmitted to the data collecting device 1.
　図１に示す構成のデータ収集システム２００においては、データ収集装置１が、各温度センサ３から温度データを取得するとともに、空調機２の温度センサ２１が検出した温度を示す温度データを空調機２から取得し、取得した各温度データを解析して、付近に人が存在する温度センサ３である代表センサを特定する。代表センサが検出する温度は付近に存在する人が発する熱の影響を受ける。すなわち、代表センサは、人が発する熱の影響を受ける温度を検出する。また、データ収集装置１は、代表センサから取得した温度データをデータ利用者端末８へ送信する、または、代表センサを示す情報と、代表センサを含む複数の温度センサ３のそれぞれから取得した温度データとをデータ利用者端末８へ送信する。 In the data collection system 200 having the configuration shown in FIG. 1, the data collection device 1 acquires temperature data from each temperature sensor 3, and the air conditioner 2 acquires temperature data indicating the temperature detected by the temperature sensor 21 of the air conditioner 2. The representative sensor, which is the temperature sensor 3 in which a person exists in the vicinity, is identified by analyzing each of the acquired temperature data obtained from the above. The temperature detected by the representative sensor is affected by the heat generated by a person in the vicinity. That is, the representative sensor detects the temperature affected by the heat generated by a person. Further, the data collecting device 1 transmits the temperature data acquired from the representative sensor to the data user terminal 8, or the information indicating the representative sensor and the temperature data acquired from each of the plurality of temperature sensors 3 including the representative sensor. To the data user terminal 8.
　図２は、実施の形態１にかかるデータ収集装置１の構成例を示す図である。図２に示すように、データ収集装置１は、観測部１０を構成するデータ取得部１１および状態検知部１２と、データ管理部１３と、データ解析部１４と、データ送信部１５とを備える。 FIG. 2 is a diagram showing a configuration example of the data collecting device 1 according to the first embodiment. As shown in FIG. 2, the data collection device 1 includes a data acquisition unit 11 and a state detection unit 12 constituting the observation unit 10, a data management unit 13, a data analysis unit 14, and a data transmission unit 15.
　データ取得部１１は、複数の温度センサ３のそれぞれから温度データを取得する。 The data acquisition unit 11 acquires temperature data from each of the plurality of temperature sensors 3.
　状態検知部１２は、空調機２の動作状態を検知する。具体的には、状態検知部１２は、空調機２の温度センサ２１から温度データを取得し、取得した温度データ、すなわち、空調機２の温度センサ２１が検出した温度に基づいて、空調機２の動作状態を検知する。状態検知部１２は、例えば、温度センサ２１が検出する温度を周期的に監視し、温度センサ２１が検出する温度の一定時間あたりの低下幅が定められたしきい値未満の状態からしきい値以上の状態に変化した場合、空調機２が冷房動作を開始したと判断する。温度の一定時間あたりの低下幅が定められたしきい値未満の状態には、温度が一定の状態および温度が上昇中の状態が含まれる。また、これとは逆に、状態検知部１２は、温度センサ２１が検出する温度の一定時間あたりの温度の上昇幅が定められたしきい値未満の状態からしきい値以上の状態に変化した場合、空調機２が冷房動作を終了したと判断する。 The state detection unit 12 detects the operating state of the air conditioner 2. Specifically, the state detection unit 12 acquires temperature data from the temperature sensor 21 of the air conditioner 2, and based on the acquired temperature data, that is, the temperature detected by the temperature sensor 21 of the air conditioner 2, the air conditioner 2 Detects the operating status of. The state detection unit 12 periodically monitors the temperature detected by the temperature sensor 21, and sets a threshold value from a state in which the amount of decrease in the temperature detected by the temperature sensor 21 per fixed time is less than a predetermined threshold value. When the above state is changed, it is determined that the air conditioner 2 has started the cooling operation. The state in which the amount of decrease in temperature per fixed time is less than a defined threshold value includes a state in which the temperature is constant and a state in which the temperature is rising. On the contrary, the state detection unit 12 has changed from a state in which the temperature rise range of the temperature detected by the temperature sensor 21 per fixed time time is less than a predetermined threshold value to a state in which the temperature rise is equal to or higher than the threshold value. In this case, it is determined that the air conditioner 2 has finished the cooling operation.
　なお、本実施の形態において、状態検知部１２は、空調機２の温度センサ２１が検出した温度に基づいて空調機２の動作状態を検知することとしたが、動作状態を検知する方法はこれに限定されない。状態検知部１２は、どのような方法で空調機２の動作状態を検知しても構わない。例えば、状態検知部１２は、空調機２の動作状態を示す情報を空調機２から取得して動作状態を把握してもよい。 In the present embodiment, the state detection unit 12 detects the operating state of the air conditioner 2 based on the temperature detected by the temperature sensor 21 of the air conditioner 2, but the method of detecting the operating state is this. Not limited to. The state detection unit 12 may detect the operating state of the air conditioner 2 by any method. For example, the state detection unit 12 may acquire information indicating the operating state of the air conditioner 2 from the air conditioner 2 to grasp the operating state.
　データ管理部１３は、データ取得部１１が取得した温度データを、温度データを取得した時刻を示す第１の時刻データと対応付けて保持する。データ管理部１３は、また、状態検知部１２による検知結果、すなわち、空調機２の動作状態を示す動作状態データを、状態検知部１２が検知を行った時刻を示す第２の時刻データと対応付けて保持する。なお、データ取得部１１が取得した温度データに時刻データが含まれるようにしてもよい。すなわち、各温度センサ３が、温度を検出した時刻を示す時刻データを含む温度データを生成するようにしてもよい。この場合、データ管理部１３は、温度データに上記の第１の時刻データを対応付けて保持する必要はない。 The data management unit 13 holds the temperature data acquired by the data acquisition unit 11 in association with the first time data indicating the time when the temperature data was acquired. The data management unit 13 also corresponds to the detection result by the state detection unit 12, that is, the operation state data indicating the operation state of the air conditioner 2, with the second time data indicating the time when the state detection unit 12 detects the operation state data. Attach and hold. The temperature data acquired by the data acquisition unit 11 may include the time data. That is, each temperature sensor 3 may generate temperature data including time data indicating the time when the temperature is detected. In this case, the data management unit 13 does not need to associate the temperature data with the above-mentioned first time data and hold it.
　データ解析部１４は、データ管理部１３が保持する温度データ、第１の時刻データ、動作状態データおよび第２の時刻データのそれぞれを解析し、付近に人が存在する温度センサ３である代表センサを特定する。 The data analysis unit 14 analyzes each of the temperature data, the first time data, the operating state data, and the second time data held by the data management unit 13, and is a representative sensor which is a temperature sensor 3 in which a person exists in the vicinity. To identify.
　データ送信部１５は、データ解析部１４による解析結果、すなわち、特定した代表センサの情報と、データ管理部１３が保持するデータの一部または全てとを、外部ネットワーク９を介してデータ利用者端末８へ送信する。 The data transmission unit 15 transmits the analysis result by the data analysis unit 14, that is, the information of the specified representative sensor and a part or all of the data held by the data management unit 13, to the data user terminal via the external network 9. Send to 8.
　つづいて、データ解析部１４が代表センサを特定する動作の詳細について、図３を参照しながら説明する。図３は、実施の形態１にかかるデータ収集装置１が備えるデータ解析部１４の動作を説明するための図である。図３では、空調機２が冷房のＯＮとＯＦＦを繰り返した場合に３つの温度センサ３が検出する温度の変化パターンの例を示している。変化パターンをＤ１～Ｄ３とする。 Next, the details of the operation of the data analysis unit 14 to identify the representative sensor will be described with reference to FIG. FIG. 3 is a diagram for explaining the operation of the data analysis unit 14 included in the data collection device 1 according to the first embodiment. FIG. 3 shows an example of a temperature change pattern detected by the three temperature sensors 3 when the air conditioner 2 repeatedly turns the air conditioner on and off. Let the change patterns be D1 to D3.
　図３に示すように、空調機２が空調を行う部屋５の中に設置された温度センサ３のそれぞれが検出する温度の変化パターンＤ１～Ｄ３は、それぞれ異なる。変化パターンに差異が生じる要因としては、空調機２と各温度センサ３との位置関係、熱源の有無などが考えられる。一般的には、空調機２に近い温度センサ３が検出する温度の時間当たりの変化は、より大きい、すなわち、変化がより急峻になる。また、空調機２が送風を行う方向に位置する温度センサ３が検出する温度の変化は、他の温度センサ３が検出する温度の変化よりも大きくなる。また、直射日光が入り込む窓に近い温度センサ３が検出する温度の変化、人などの熱源に近い温度センサ３が検出する温度の変化は、他の温度センサ３が検出する温度の変化よりも小さくなる。よって、人が近くに存在する温度センサ３が検出する温度の変化パターンは、人が近くに存在しない温度センサ３が検出する温度の変化パターンとは異なる。これは、熱源である人に近い温度センサ３が検出する温度は、人が発する熱すなわち体温の影響を受けるためである。したがって、温度の変化パターンを解析することで、変化パターンに対応する温度センサ３の近くに人が存在するか否かを判別することが可能である。 As shown in FIG. 3, the temperature change patterns D1 to D3 detected by each of the temperature sensors 3 installed in the room 5 in which the air conditioner 2 air-conditions are different. Factors that cause a difference in the change pattern include the positional relationship between the air conditioner 2 and each temperature sensor 3, the presence or absence of a heat source, and the like. In general, the change in temperature per hour detected by the temperature sensor 3 close to the air conditioner 2 is larger, that is, the change becomes steeper. Further, the change in temperature detected by the temperature sensor 3 located in the direction in which the air conditioner 2 blows air is larger than the change in temperature detected by the other temperature sensors 3. Further, the change in temperature detected by the temperature sensor 3 near the window into which direct sunlight enters and the change in temperature detected by the temperature sensor 3 near the heat source such as a person are smaller than the change in temperature detected by the other temperature sensors 3. Become. Therefore, the temperature change pattern detected by the temperature sensor 3 in which a person is nearby is different from the temperature change pattern detected by the temperature sensor 3 in which a person is not nearby. This is because the temperature detected by the temperature sensor 3 close to the person, which is the heat source, is affected by the heat generated by the person, that is, the body temperature. Therefore, by analyzing the temperature change pattern, it is possible to determine whether or not a person exists near the temperature sensor 3 corresponding to the change pattern.
　そのため、本実施の形態にかかるデータ解析部１４は、空調機２が冷房をオンオフさせたときの、人が近くに存在する温度センサ３が検出する温度の変化パターンのデータを保持しておき、保持しているデータが示す温度の変化パターンである基準パターンに一致または類似する変化パターンとなる温度を検出する温度センサ３を代表センサとする。基準パターンのデータは、例えば、温度センサ３と同様の温度センサと、空調機２と同様の空調機とを使用し、温度センサの近くに人が存在する状態で空調機による冷房をオンオフさせたときに温度センサが検出する温度の変化パターンを観測し、作成する。基準パターンのデータを作成する際には、人が近くに存在する温度センサと空調機との位置関係を変化させながら、温度センサが検出する温度の変化パターンの観測を複数回にわたって行い、観測した複数の変化パターンの平均を基準パターンとする。 Therefore, the data analysis unit 14 according to the present embodiment holds data of the temperature change pattern detected by the temperature sensor 3 in the vicinity of a person when the air conditioner 2 turns the air conditioner on and off. A representative sensor is a temperature sensor 3 that detects a temperature having a change pattern that matches or is similar to a reference pattern that is a temperature change pattern indicated by the held data. For the data of the reference pattern, for example, a temperature sensor similar to the temperature sensor 3 and an air conditioner similar to the air conditioner 2 were used, and cooling by the air conditioner was turned on and off in a state where a person was present near the temperature sensor. Occasionally observe and create a temperature change pattern detected by a temperature sensor. When creating the reference pattern data, the temperature change pattern detected by the temperature sensor was observed multiple times while changing the positional relationship between the temperature sensor near the person and the air conditioner. The average of multiple change patterns is used as the reference pattern.
　データ解析部１４は、予め定められた条件を満たすと、まず、データ管理部１３が保持する温度データ、第１の時刻データ、動作状態データおよび第２の時刻データを解析し、各温度センサ３が検出した温度の変化パターンを算出する。上記の予め定められた条件の例は、代表センサを特定する動作を前回行ってから定められた時間が経過した場合である。また、他の例として、代表センサを特定する動作を前回行った後にデータ管理部１３に新たに蓄積された温度データの数が、定められた数に達した場合、などが該当する。 When the data analysis unit 14 satisfies the predetermined conditions, the data analysis unit 14 first analyzes the temperature data, the first time data, the operation state data, and the second time data held by the data management unit 13, and each temperature sensor 3 Calculates the temperature change pattern detected by. An example of the above-mentioned predetermined conditions is a case where a predetermined time has elapsed since the operation of specifying the representative sensor was performed last time. Further, as another example, the case where the number of temperature data newly accumulated in the data management unit 13 after the operation of specifying the representative sensor reaches a predetermined number is applicable.
　データ解析部１４は、各温度センサ３が検出した温度の変化パターンを算出すると、次に、算出した変化パターンのそれぞれについて、基準パターンと一致または類似するかを判定する。ここでの判定は、パターンマッチングによって行う。データ解析部１４は、例えば、冷房オフの状態から冷房オンの状態に変化した後の、基準パターンにおける温度変化の傾きと、算出した変化パターンにおける温度変化の傾きとを比較し、また、冷房オンの状態から冷房オフの状態に変化した後の、基準パターンにおける温度変化の傾きと、算出した変化パターンにおける温度変化の傾きとを比較し、比較結果から、算出した変化パターンが基準パターンと一致または類似するかを判定する。なお、データ解析部１４は、算出した変化パターンと基準パターンとの相関値を求め、相関値が予め定められたしきい値以上の場合に、算出した変化パターンが基準パターンと類似すると判定してもよい。 The data analysis unit 14 calculates the temperature change pattern detected by each temperature sensor 3, and then determines whether each of the calculated change patterns matches or is similar to the reference pattern. The determination here is performed by pattern matching. The data analysis unit 14 compares, for example, the slope of the temperature change in the reference pattern and the slope of the temperature change in the calculated change pattern after the change from the cooling off state to the cooling on state, and also cools on. The slope of the temperature change in the reference pattern after changing from the state of to the state of cooling off is compared with the slope of the temperature change in the calculated change pattern, and from the comparison result, the calculated change pattern matches the reference pattern or Determine if they are similar. The data analysis unit 14 obtains a correlation value between the calculated change pattern and the reference pattern, and determines that the calculated change pattern is similar to the reference pattern when the correlation value is equal to or higher than a predetermined threshold value. May be good.
　つづいて、データ収集装置１の全体動作について、図４を用いて説明する。図４は、実施の形態１にかかるデータ収集装置１の動作の一例を示すフローチャートである。 Next, the overall operation of the data collection device 1 will be described with reference to FIG. FIG. 4 is a flowchart showing an example of the operation of the data collecting device 1 according to the first embodiment.
　図４のフローチャートが示す動作は、空調機２の冷房がオフ（ＯＦＦ）の状態から開始される。 The operation shown in the flowchart of FIG. 4 is started from the state where the cooling of the air conditioner 2 is OFF.
　データ収集装置１は、まず、各温度センサ、具体的には、各温度センサ３および空調機２の温度センサ２１から温度データを取得する（ステップＳ１）。データ収集装置１は、その後、一定時間が経過後に各温度センサ（各温度センサ３，温度センサ２１）から温度データを取得する（ステップＳ２）。 The data collecting device 1 first acquires temperature data from each temperature sensor, specifically, each temperature sensor 3 and the temperature sensor 21 of the air conditioner 2 (step S1). The data collecting device 1 then acquires temperature data from each temperature sensor (each temperature sensor 3, temperature sensor 21) after a lapse of a certain period of time (step S2).
　データ収集装置１は、次に、冷房ＯＮか否か、すなわち、冷房がオンの状態に変化したか否かを確認する（ステップＳ３）。冷房ＯＮか否かは、状態検知部１２が、空調機２の温度センサ２１から取得した温度データに基づいて判定する。冷房ＯＮではない場合（ステップＳ３：Ｎｏ）、データ収集装置１は、ステップＳ２に戻り動作を続ける。 Next, the data collecting device 1 confirms whether or not the cooling is ON, that is, whether or not the cooling has changed to the ON state (step S3). Whether or not cooling is ON is determined by the state detection unit 12 based on the temperature data acquired from the temperature sensor 21 of the air conditioner 2. When the cooling is not ON (step S3: No), the data collecting device 1 returns to step S2 and continues the operation.
　冷房ＯＮの場合（ステップＳ３：Ｙｅｓ）、データ収集装置１は、冷房ＯＮ状態を記憶する、すなわち、冷房がオフ状態からオン状態に変化したことを記憶する（ステップＳ４）。このステップＳ４では、冷房がオフ状態からオン状態に変化したことを示す動作状態データを状態検知部１２が生成し、この動作状態データを、上述した第２の時刻データに相当する現在時刻データと対応付けて、データ管理部１３が保持する。 When the air conditioner is ON (step S3: Yes), the data collecting device 1 stores the air conditioner ON state, that is, stores that the air conditioner has changed from the off state to the on state (step S4). In step S4, the state detection unit 12 generates operation state data indicating that the cooling has changed from the off state to the on state, and the operation state data is combined with the current time data corresponding to the second time data described above. The data management unit 13 holds the data in association with each other.
　データ収集装置１は、その後、一定時間が経過後に各温度センサ（各温度センサ３，温度センサ２１）から温度データを取得する（ステップＳ５）。 The data collecting device 1 then acquires temperature data from each temperature sensor (each temperature sensor 3, temperature sensor 21) after a certain period of time has elapsed (step S5).
　データ収集装置１は、次に、冷房ＯＦＦか否か、すなわち、冷房がオフの状態に変化したか否かを確認する（ステップＳ６）。冷房ＯＦＦか否かは、状態検知部１２が、空調機２の温度センサ２１から取得した温度データに基づいて判定する。冷房ＯＦＦではない場合（ステップＳ６：Ｎｏ）、データ収集装置１は、ステップＳ５に戻り動作を続ける。 Next, the data collecting device 1 confirms whether or not the cooling is OFF, that is, whether or not the cooling has changed to the OFF state (step S6). Whether or not cooling is OFF is determined by the state detection unit 12 based on the temperature data acquired from the temperature sensor 21 of the air conditioner 2. If the cooling is not OFF (step S6: No), the data collecting device 1 returns to step S5 and continues the operation.
　冷房ＯＦＦの場合（ステップＳ６：Ｙｅｓ）、データ収集装置１は、冷房ＯＦＦ状態を記憶する、すなわち、冷房がオン状態からオフ状態に変化したことを記憶する（ステップＳ７）。このステップＳ７では、冷房がオン状態からオフ状態に変化したことを示す動作状態データを状態検知部１２が生成し、この動作状態データを、上述した第２の時刻データに相当する現在時刻データと対応付けて、データ管理部１３が保持する。 In the case of cooling OFF (step S6: Yes), the data collecting device 1 stores the cooling OFF state, that is, stores that the cooling has changed from the ON state to the OFF state (Step S7). In step S7, the state detection unit 12 generates operation state data indicating that the cooling has changed from the on state to the off state, and the operation state data is combined with the current time data corresponding to the second time data described above. The data management unit 13 holds the data in association with each other.
　データ収集装置１は、その後、一定時間が経過後に各温度センサ（各温度センサ３，温度センサ２１）から温度データを取得する（ステップＳ８）。 The data collecting device 1 then acquires temperature data from each temperature sensor (each temperature sensor 3, temperature sensor 21) after a certain period of time has elapsed (step S8).
　データ収集装置１は、次に、冷房ＯＮか否か、すなわち、冷房がオンの状態に変化したか否かを確認する（ステップＳ９）。このステップＳ９は上述したステップＳ３と同様の処理である。冷房ＯＮではない場合（ステップＳ９：Ｎｏ）、データ収集装置１は、ステップＳ８に戻り動作を続ける。 Next, the data collecting device 1 confirms whether or not the cooling is ON, that is, whether or not the cooling has changed to the ON state (step S9). This step S9 is the same process as step S3 described above. When the cooling is not ON (step S9: No), the data collecting device 1 returns to step S8 and continues the operation.
　冷房ＯＮの場合（ステップＳ９：Ｙｅｓ）、データ収集装置１は、一定回数観測を実施したか、すなわち、冷房ＯＮおよび冷房ＯＦＦの観測回数が予め定められた一定の値に達したかを確認する（ステップＳ１０）。データ収集装置１は、一定回数観測を実施していない場合（ステップＳ１０：Ｎｏ）、ステップＳ４に戻り動作を続ける。 In the case of cooling ON (step S9: Yes), the data collecting device 1 confirms whether the observations have been performed a certain number of times, that is, whether the number of observations of cooling ON and cooling OFF has reached a predetermined constant value. (Step S10). When the data collecting device 1 has not performed the observation a certain number of times (step S10: No), the data collecting device 1 returns to step S4 and continues the operation.
　データ収集装置１は、一定回数観測を実施した場合（ステップＳ１０：Ｙｅｓ）、保持しているデータ、すなわち、上記のステップＳ１～Ｓ１０を実行することで得られた温度データ、第１の時刻データ、動作状態データおよび第２の時刻データを解析して、代表の温度センサを特定する（ステップＳ１１）。このステップＳ１１では、データ解析部１４が、データ管理部１３が保持している各データを使用し、上述した方法で、各温度センサ３が検出した温度の変化パターンを算出し、さらに、算出した各変化パターンの中から基準パターンと一致または類似する変化パターンを探し出し、該当する変化パターンとなる温度を検出した温度センサ３を代表センサ（代表の温度センサ）とする。なお、データ解析部１４は、基準パターンと一致または類似する変化パターンが複数存在する場合、それぞれの変化パターンに対応する各温度センサ３を代表センサとする。一方、データ解析部１４は、基準パターンと一致または類似する変化パターンが存在しない場合、代表センサが存在しないと判断する。 When the data collecting device 1 performs the observation a certain number of times (step S10: Yes), the retained data, that is, the temperature data obtained by executing the above steps S1 to S10, the first time data. , The operating state data and the second time data are analyzed to identify a representative temperature sensor (step S11). In this step S11, the data analysis unit 14 uses each data held by the data management unit 13 to calculate the temperature change pattern detected by each temperature sensor 3 by the method described above, and further calculates the temperature change pattern. A temperature sensor 3 that finds a change pattern that matches or is similar to the reference pattern from each change pattern and detects a temperature that is the corresponding change pattern is used as a representative sensor (representative temperature sensor). When there are a plurality of change patterns that match or are similar to the reference pattern, the data analysis unit 14 uses each temperature sensor 3 corresponding to each change pattern as a representative sensor. On the other hand, the data analysis unit 14 determines that the representative sensor does not exist when there is no change pattern that matches or is similar to the reference pattern.
　データ収集装置１は、次に、代表の温度センサ３から取得した温度データを、外部ネットワーク９を介してデータ利用者端末８へ送信する（ステップＳ１２）。ステップＳ１２において、データ収集装置１は、代表の温度センサ３から過去のある時から現在までの間に取得して保持している温度データと温度データに関連するデータとをデータ利用者端末８に向けて送信する。温度データに関連するデータには、上述した第１の時刻データ、代表の温度センサ３の識別情報などが該当する。なお、図４に示すステップＳ１２では、代表の温度センサ３から取得した温度データおよびこれに関連するデータをデータ利用者端末８へ送信することとしたがこれに限定されない。ステップＳ１２において、データ収集装置１は、代表ではない温度センサ３から取得した温度データおよびこれに関連するデータについても、代表の温度センサ３から取得した温度データなどと一緒に送信するようにしてもよい。例えば、データ収集装置１のデータ送信部１５は、代表の温度センサ３を含む全ての温度センサ３から取得した温度データと、代表の温度センサ３の情報とをデータ利用者端末８へ送信してもよい。代表の温度センサ３の情報は、データ利用者端末８が代表の温度センサ３を知ることができる情報であればよく、例えば、代表の温度センサ３の識別情報が該当する。また、データ収集装置１は、ステップＳ１２で温度データ等を送信する相手を空調機２としてもよい。この場合、空調機２は、代表の温度センサ３が検出する温度が、設定温度に近づくよう冷房を行い、代表の温度センサ３の近くに存在するユーザの快適性を向上させることができる。 Next, the data collecting device 1 transmits the temperature data acquired from the representative temperature sensor 3 to the data user terminal 8 via the external network 9 (step S12). In step S12, the data collecting device 1 transfers the temperature data acquired and held from the representative temperature sensor 3 from a certain time in the past to the present and the data related to the temperature data to the data user terminal 8. Send to. The data related to the temperature data includes the above-mentioned first time data, identification information of the representative temperature sensor 3, and the like. In step S12 shown in FIG. 4, the temperature data acquired from the representative temperature sensor 3 and the data related thereto are transmitted to the data user terminal 8, but the present invention is not limited to this. In step S12, the data collecting device 1 may transmit the temperature data acquired from the non-representative temperature sensor 3 and the data related thereto together with the temperature data acquired from the representative temperature sensor 3 and the like. Good. For example, the data transmission unit 15 of the data collection device 1 transmits the temperature data acquired from all the temperature sensors 3 including the representative temperature sensor 3 and the information of the representative temperature sensor 3 to the data user terminal 8. May be good. The information of the representative temperature sensor 3 may be any information as long as the data user terminal 8 can know the representative temperature sensor 3, and for example, the identification information of the representative temperature sensor 3 corresponds to the information. Further, the data collecting device 1 may use the air conditioner 2 as a partner for transmitting temperature data or the like in step S12. In this case, the air conditioner 2 can cool the air conditioner 2 so that the temperature detected by the representative temperature sensor 3 approaches the set temperature, and can improve the comfort of the user who exists near the representative temperature sensor 3.
　なお、データ収集装置１は、ステップＳ１２を実行した後、ステップＳ４に戻り動作を続けてもよい。 Note that the data collection device 1 may return to step S4 and continue the operation after executing step S12.
　以上のように、本実施の形態にかかるデータ収集システム２００のデータ収集装置１は、複数の温度センサ３のそれぞれから取得した温度データと、空調機２の動作状態を示す動作状態データとに基づいて、各温度センサ３が検出する温度の変化パターンを算出し、算出した変化パターンに基づいて、人の近くに存在する温度センサ３である代表センサを特定する。データ収集装置１によれば、複数の温度センサ３のそれぞれから得られる温度データのうち、人が近くに存在する温度センサである代表センサから得られる温度データを特定することができる。 As described above, the data collecting device 1 of the data collecting system 200 according to the present embodiment is based on the temperature data acquired from each of the plurality of temperature sensors 3 and the operating state data indicating the operating state of the air conditioner 2. Then, the temperature change pattern detected by each temperature sensor 3 is calculated, and the representative sensor, which is the temperature sensor 3 existing near the person, is specified based on the calculated change pattern. According to the data collecting device 1, among the temperature data obtained from each of the plurality of temperature sensors 3, the temperature data obtained from the representative sensor, which is a temperature sensor in which a person exists nearby, can be specified.

Further, when the relay device 4 receives the signal addressed to the air conditioner 2 from the data collecting device 1, the relay device 4 transfers the signal to the air conditioner 2, and when the relay device 4 receives the signal addressed to the temperature sensor 3 from the data collecting device 1, the temperature sensor Transfer to 3.
