Description

空調システムAir conditioning system
　本発明は、建物に設置された空調システムに関する。 The present invention relates to an air conditioning system installed in a building.
　建物に設置された空調機では、室外機と室内機との間の通信又は室内機と室内機との間の通信が有線で行われることが一般的である。 In an air conditioner installed in a building, communication between an outdoor unit and an indoor unit or communication between an indoor unit and an indoor unit is generally performed by wire.
　室内機と室内機との間の通信を無線化することで、室内機への信号伝送用ケーブルの接続が不要になり、建物内の空調空間への室内機の配置の自由度が高まる。室内機と室内機との間の通信を無線化する場合、空調空間に設置された無線ＬＡＮ（Ｌｏｃａｌ　Ａｒｅａ　Ｎｅｔｗｏｒｋ）ルータに室外機を接続し、ＬＡＮ回線を介して無線ＬＡＮルータと室内機とを接続する方法が考えられる。この構成により、室外機と室内機との通信が実現される。 By wirelessly communicating between the indoor unit and the indoor unit, connection of a signal transmission cable to the indoor unit becomes unnecessary, and the degree of freedom of arrangement of the indoor unit in the air-conditioned space in the building is increased. When the communication between the indoor unit and the indoor unit is made wireless, the outdoor unit is connected to the wireless LAN (Local Area Network) router installed in the air-conditioned space, and the wireless LAN router and the indoor unit are connected via the LAN line. A method of connecting is conceivable. With this configuration, communication between the outdoor unit and the indoor unit is realized.
　上記の接続方法では、室外機、室内機及び無線ＬＡＮルータの設置の際、これらの機器に通信設定を実施する必要が生じる。そのため室外機、室内機及び無線ＬＡＮルータの設置作業の効率が悪い。また上記の接続方法では、無線ＬＡＮ通信時に機器間の無線通信区間の距離を十分に確保できる送信出力及び受信感度を有する無線モジュールを室内機に搭載する必要があるため、空調機器のコスト増加を招く。これらの問題は、建物内に設置される室内機の数が増加するほど顕著になる。 In the above connection method, it is necessary to perform communication settings for these devices when installing outdoor units, indoor units, and wireless LAN routers. For this reason, the efficiency of installing the outdoor unit, the indoor unit, and the wireless LAN router is poor. Further, in the above connection method, it is necessary to install a wireless module having a transmission output and a reception sensitivity that can sufficiently secure a distance of a wireless communication section between devices during wireless LAN communication, which increases the cost of air conditioning equipment. Invite. These problems become more prominent as the number of indoor units installed in the building increases.
　上記のような問題を解決する方法の一例としては、通信機能を有する複数の室内機同士が相互に通信を行うメッシュ通信が考えられる。複数の室内機同士が相互に通信を行うことにより、制御指令データ及び運転状態データといった空調システムの運転に必要な情報を複数の室内機のそれぞれが転送する構成となる。この構成により、高い送信出力及び受信感度を有する無線モジュールを利用しなくとも低コストでネットワークを構築できる。 As an example of a method for solving the above problems, mesh communication in which a plurality of indoor units having a communication function communicate with each other is conceivable. When a plurality of indoor units communicate with each other, each of the plurality of indoor units transfers information necessary for operation of the air conditioning system, such as control command data and operation state data. With this configuration, it is possible to construct a network at a low cost without using a wireless module having high transmission output and reception sensitivity.
　一方、特許文献１には無線通信の信頼性を高める技術として、無線メッシュネットワークを用いて、フェージング環境下においても広域に分布して配置された多数のノードを短時間かつ高い信頼度で制御可能にする技術が開示されている。特許文献１に開示される無線メッシュネットワークシステムでは、制御用ノードが、複数のマルチキャスト用ノードの各々を宛先として、制御データを含むマルチキャスト生成用フレームをマルチキャストで送信し、マルチキャスト生成用フレームを受信したマルチキャスト用ノードが、受信したマルチキャスト生成用フレームに含まれる複数の宛先アドレスの中から自ノードのアドレスを削除して、当該アドレスを削除したマルチキャスト生成用フレームをマルチキャストで転送する、というアルゴリズムが繰り返される。これにより、制御対象ノードに対しては、フェージング環境下においても、広域に分布して配置された多数のノードを短時間かつ高い信頼度で制御可能となる。 On the other hand, in Patent Document 1, as a technique for improving the reliability of wireless communication, a wireless mesh network can be used to control a large number of nodes distributed over a wide area even in a fading environment in a short time with high reliability.

Waiting for reception of the wireless transmission frame 20 including the transmitted operation state data.
　上記の一定時間の間に、親室内機４１及び子室内機４２ｂのそれぞれから運転状態データを重複して受信した場合、最初に受信した運転状態データを利用し、この運転状態データ以外の運転状態データは利用しない。 When the operation state data is received redundantly from each of the parent indoor unit 41 and the child indoor unit 42b during the above-described fixed time, the operation state data other than the operation state data is used by using the operation state data received first. Data is not used.
　運転状態データが重複しているか否かの判定方法は、無線伝送フレーム２０に含まれる送信時刻２６及び送信元ユニットＩＤ２４を比較し、これらが同一である場合、運転状態データが重複していると判定され、これらが同一ではない場合、運転状態データが重複していないと判定される。 The method for determining whether or not the operation state data is duplicated is that the transmission time 26 and the transmission source unit ID 24 included in the wireless transmission frame 20 are compared, and if these are the same, the operation state data is duplicated. If they are not the same, it is determined that the operation state data is not duplicated.
　このように子室内機４２ａは、運転状態データの要求指令を含む無線伝送フレーム２０の送信動作と、運転状態データを含む無線伝送フレーム２０の受信動作とを一定周期で実行する。 As described above, the sub indoor unit 42a executes the transmission operation of the wireless transmission frame 20 including the operation state data request command and the reception operation of the wireless transmission frame 20 including the operation state data at a constant cycle.
　これらの動作は、子室内機４２ａと１つの子室内機４２ｂとの間だけでなく、子室内機４２ａと隣接する２つの子室内機４２ｂとの間でも実行される。またこれらの動作は、隣接する子室内機４２ｂ同士の間でも実行され、隣接する子室内機４２ｃ同士でも実行される。 These operations are performed not only between the child indoor unit 42a and one child indoor unit 42b, but also between the child indoor unit 42a and two adjacent child indoor units 42b. These operations are also executed between adjacent child indoor units 42b, and are also executed between adjacent child indoor units 42c.
　子室内機４２ａは、隣接する２つの子室内機４２ｂから送信された運転状態データと、自機が保持する運転状態データとを比較する。 The child indoor unit 42a compares the operation state data transmitted from the two adjacent child indoor units 42b with the operation state data held by itself.
　比較の結果、３つの運転状態データが同一の場合、子室内機４２ａは、自機の運転状態の更新は行わない。３つの運転状態データが同一ではない場合、子室内機４２ａは、３つの運転状態データの多数決を取り、その結果、多数となった運転状態データが正のデータであると判定する。 As a result of comparison, when the three operation state data are the same, the child indoor unit 42a does not update the operation state of the own unit. If the three operation state data are not the same, the sub indoor unit 42a takes a majority decision of the three operation state data, and as a result, determines that the operation state data that has become a large number is positive data.
　そして、子室内機４２ａは、自機が保持する運転状態データを、正のデータと判定した運転状態データに更新する。これにより、子室内機４２ａでは、隣接する２つの子室内機４２ｂと同様の運転が実施される。 Then, the indoor unit 42a updates the operation state data held by itself to the operation state data determined to be positive data. Thereby, in the child indoor unit 42a, the same operation as that of the two adjacent child indoor units 42b is performed.
　なお、子室内機群４２のそれぞれは、少なくとも３つの運転状態データを比較するものとし、複数の運転状態データが隣接する室内機から取得できない場合、上記の一定時間が経過した後、再度、運転状態データの要求指令を含む無線伝送フレーム２０を送信する。 Each of the sub indoor unit groups 42 compares at least three operation state data, and when a plurality of operation state data cannot be acquired from adjacent indoor units, the operation is performed again after the predetermined time has elapsed. A wireless transmission frame 20 including a state data request command is transmitted.
　なお、隣接する子室内機４２ｂ同士、また隣接する子室内機４２ｃ同士においても、運転状態データの要求指令を含む無線伝送フレーム２０の送信動作と、運転状態データを含む無線伝送フレーム２０の受信動作とが一定周期で実行され、さらに運転状態データが重複しているか否かの判定動作がなされる。 Note that the transmission operation of the wireless transmission frame 20 including the operation state data request command and the reception operation of the wireless transmission frame 20 including the operation state data also between the adjacent child indoor units 42b and between the adjacent child indoor units 42c. Are executed at a constant cycle, and further, an operation for determining whether or not the operation state data is duplicated is performed.
　次に子室内機群４２から親室内機４１へ運転状態データを送信する通信動作について説明する。この通信動作は、子室内機群４２内の何れかの室内機で異常が生じたとき、その異常内容を示すデータを運転状態データとして親室内機４１へ送信するために実行される。 Next, a communication operation for transmitting operation state data from the child indoor unit group 42 to the parent indoor unit 41 will be described. This communication operation is executed to transmit data indicating the content of the abnormality to the parent indoor unit 41 as operating state data when an abnormality occurs in any of the indoor units in the sub indoor unit group 42.
　図５は子室内機群内から親室内機へ運転状態データを含む無線伝送フレームが伝送される際の動作を説明するための通信シーケンスを示す図である。 FIG. 5 is a diagram showing a communication sequence for explaining an operation when a wireless transmission frame including operation state data is transmitted from the sub indoor unit group to the parent indoor unit.
　Ｓ３０１において、複数の子室内機４２ｃのそれぞれは、運転状態データを含む無線伝送フレーム２０を、隣接する複数の子室内機４２ｂのそれぞれに送信する。 In S301, each of the plurality of sub indoor units 42c transmits the wireless transmission frame 20 including the operation state data to each of the plurality of adjacent sub indoor units 42b.

In the transmission source unit ID 24 of the wireless transmission frame 20, the identifier of the child indoor unit 42c is set. In the communication content 25, the operation state data of the child indoor unit 42c is set.
　Ｓ３０２において、複数の子室内機４２ｂのそれぞれは、隣接する子室内機４２ｃから送信された無線伝送フレーム２０を受信し、子室内機４２ａへ転送する。 In S302, each of the plurality of sub indoor units 42b receives the wireless transmission frame 20 transmitted from the adjacent sub indoor unit 42c and transfers it to the sub indoor unit 42a.
　Ｓ３０３において、子室内機４２ａは、複数の子室内機４２ｂのそれぞれから送信された無線伝送フレーム２０を受信し、親室内機４１へ転送する。 In S303, the child indoor unit 42a receives the wireless transmission frame 20 transmitted from each of the plurality of child indoor units 42b, and transfers it to the parent indoor unit 41.
　親室内機４１は、子室内機４２ａから送信された無線伝送フレーム２０を受信すると、無線伝送フレーム２０に含まれる運転状態データに基づいて、子室内機群４２の異常内容を示すメッセージ情報を生成し、生成したメッセージ情報を無線伝送フレーム２０に含めてリモコン５へ伝送する。これにより、リモコン５の表示器には子室内機群４２の異常内容が示されるため、リモコン５のユーザは異常内容を知ることができる。 When receiving the wireless transmission frame 20 transmitted from the child indoor unit 42a, the parent indoor unit 41 generates message information indicating the abnormal content of the child indoor unit group 42 based on the operation state data included in the wireless transmission frame 20. The generated message information is included in the wireless transmission frame 20 and transmitted to the remote controller 5. Thereby, since the abnormal content of the sub indoor unit group 42 is shown on the display of the remote controller 5, the user of the remote controller 5 can know the abnormal content.
　親室内機４１は、上記の一定時間毎に子室内機４２ａから送信される無線伝送フレーム２０に含まれる運転状態データが重複しているか否かを判定する。 The parent indoor unit 41 determines whether or not the operation state data included in the wireless transmission frame 20 transmitted from the child indoor unit 42a is duplicated at the predetermined time intervals.
　運転状態データが重複する場合、親室内機４１は、最初に受信した運転状態データを利用し、この運転状態データ以外の運転状態データは利用しない。 When the operation state data is duplicated, the parent indoor unit 41 uses the operation state data received first, and does not use operation state data other than the operation state data.
　運転状態データが重複しているか否かの判定方法は、無線伝送フレーム２０に含まれる送信時刻２６及び送信元ユニットＩＤ２４を比較し、これらが同一である場合、運転状態データが重複していると判定され、これらが同一ではない場合、運転状態データが重複していないと判定される。 The method for determining whether or not the operation state data is duplicated is that the transmission time 26 and the transmission source unit ID 24 included in the wireless transmission frame 20 are compared, and if these are the same, the operation state data is duplicated. If they are not the same, it is determined that the operation state data is not duplicated.
