Description

リモートコントローラおよび空気調和システムRemote controller and air conditioning system
　この発明は、リモートコントローラおよび空気調和システムに関するものである。特に、リモートコントローラと室内機との間に発生した通信異常に対する制御に関するものである。 The present invention relates to a remote controller and an air conditioning system. In particular, it relates to control for a communication abnormality that occurs between the remote controller and the indoor unit.
　従来、空気調和装置などにおいて、通信異常が発生したときの影響を抑える技術が提案されている。たとえば、室外機と複数の室内機とが通信線で接続された空気調和機において、１台の室内機に通信異常が発生すると、通信異常が発生していない室内機の通信線を介して、通信異常に係る室内機を操作制御する方法がある（たとえば、特許文献１参照）。 Conventionally, in air conditioners and the like, technologies for suppressing the influence when a communication abnormality occurs have been proposed. For example, in an air conditioner in which an outdoor unit and a plurality of indoor units are connected by a communication line, when a communication abnormality occurs in one indoor unit, the communication line of the indoor unit in which the communication abnormality does not occur is used. There is a method of operating and controlling an indoor unit related to a communication abnormality (see, for example, Patent Document 1).
　また、複数の空調ユニットを一括管理する集中制御ユニットを有する空気調和システムにおいて、室外機内のスイッチングハブを用いて、通信異常が発生している通信路を使わず、他の通信路に切り替えて通信を行うシステムがある（たとえば、特許文献２参照）。 Further, in an air conditioning system having a centralized control unit that collectively manages a plurality of air conditioning units, a switching hub in the outdoor unit is used to switch to another communication path for communication without using the communication path in which a communication abnormality has occurred. (See, for example, Patent Document 2).

　一方、従来の空気調和装置において、空気調和装置の室内機と操作者の操作を室内機に送るリモートコントローラとの間で、一時的または長期に通信異常が発生することがある。室内機とリモートコントローラとの間で通信異常が発生した場合、室内機は、運転を停止する。このため、空気調和装置本体および冷暖房システムとして異常はないのに、再度、室内機を運転させるためには、操作者が異常を解除しなければならなかった。 On the other hand, in the conventional air conditioner, a communication abnormality may occur temporarily or for a long period of time between the indoor unit of the air conditioner and the remote controller that sends the operation of the operator to the indoor unit. If a communication error occurs between the indoor unit and the remote controller, the indoor unit stops operating. Therefore, although there is no abnormality in the air conditioner main body and the air conditioning system, the operator has to clear the abnormality in order to operate the indoor unit again.
　この発明は、上記のような課題を解決するため、空気調和装置とリモートコントローラとの間に通信異常が発生しても、室内機を運転させることができるリモートコントローラおよび空気調和システムを得ることを目的とする。 In order to solve the above problems, the present invention provides a remote controller and an air conditioning system capable of operating an indoor unit even if a communication abnormality occurs between the air conditioner and the remote controller.

It has an abnormality detection processing unit for operating the remote controller.
　また、この発明に係る空気調和システムは、対象空間の空気調和を行う複数の室内機と、室内機と配管接続して冷媒を循環させる冷媒回路を構成し、室内機に熱を送る室外機と、室外機および室内機を管理するシステムコントローラとが接続され、複数のリモートコントローラが、それぞれ操作対象の室内機と接続されて通信を行う空気調和システムであって、リモートコントローラは、他のリモートコントローラと無線通信を行う無線通信部と、操作対象の室内機との間の通信異常を検知すると、操作対象の室内機の運転を要求する補助操作要求に係る信号を生成し、補助操作要求に係る信号を、無線通信部から送信させ、他のリモートコントローラを介して、システムコントローラに送信する異常検知処理部とを有し、システムコントローラは、補助操作要求に係る信号に基づいて、操作対象の室内機に、運転操作に係る信号を送るものである。 Further, the air conditioning system according to the present invention comprises a plurality of indoor units that harmonize the air in the target space, and an outdoor unit that connects the indoor unit with a pipe to circulate the refrigerant and sends heat to the indoor unit. , The system controller that manages the outdoor unit and the indoor unit is connected, and a plurality of remote controllers are connected to the indoor unit to be operated and communicate with each other. The remote controller is another remote controller. When a communication abnormality between the wireless communication unit that performs wireless communication with and the indoor unit to be operated is detected, a signal related to an auxiliary operation request requesting the operation of the indoor unit to be operated is generated, and the auxiliary operation request is related. It has an abnormality detection processing unit that transmits a signal from the wireless communication unit and transmits it to the system controller via another remote controller, and the system controller is in the operation target room based on the signal related to the auxiliary operation request. It sends a signal related to the operation to the machine.
　この発明によれば、リモートコントローラは、無線通信部を有し、別のリモートコントローラと無線接続による通信を行えるようにした。異常検知処理部が操作対象となる室内機との間の通信異常を検知したときには、別のリモートコントローラを介して、操作対象となる室内機を操作できるようにした。このため、リモートコントローラと室内機との間で通信異常が発生しても、停止した室内機の運転を再開することができ、運転の継続をはかることができる。 According to the present invention, the remote controller has a wireless communication unit so that it can communicate with another remote controller by wireless connection. When the abnormality detection processing unit detects a communication error with the indoor unit to be operated, the indoor unit to be operated can be operated via another remote controller. Therefore, even if a communication abnormality occurs between the remote controller and the indoor unit, the operation of the stopped indoor unit can be restarted, and the operation can be continued.

Then, the indoor operation communication unit 31 of the outdoor unit 2a sends a signal related to the operation of operation ON to the indoor unit 3a via the operation communication line 200a (FIGS. 7 and 8 (6)).
　室内機３ａの室内側操作用通信部３１は、室外機２ａからの運転ＯＮの運転操作に係る信号を受信する。室内機３ａは、運転ＯＮの運転操作に基づいて、通信異常発生により停止していた運転を再開する。 The indoor operation communication unit 31 of the indoor unit 3a receives a signal related to the operation ON operation from the outdoor unit 2a. The indoor unit 3a resumes the operation that had been stopped due to the occurrence of a communication abnormality, based on the operation of the operation ON.
　一方、室内機３ａの室内側異常検知処理部３２においても、操作用通信線２００ｂに異常が発生したことを検知する。室内機３ａの室内側異常検知処理部３２は、通信異常を検知すると、室内機３ａの運転を停止させる。そして、室内側異常検知処理部３２は、室内側記憶部３４から、該当する異常コードのデータを読み出す。ここで、異常コードとは、発生した異常内容を、数字などによって簡易に示すコードである。たとえば、通信異常の場合は、「６６０６」などとする。そして、室内機３ａの室内側操作用通信部３１は、操作用通信線２００ａを介して、異常コードのデータを含む信号を、室外機２ａに送る（図７および図８（１１））。 On the other hand, the indoor side abnormality detection processing unit 32 of the indoor unit 3a also detects that an abnormality has occurred in the operation communication line 200b.

Then, the indoor side abnormality detection processing unit 32 reads out the data of the corresponding abnormality code from the indoor side storage unit 34. Here, the abnormality code is a code that simply indicates the content of the abnormality that has occurred by means of numbers or the like. For example, in the case of a communication abnormality, it is set to "6606" or the like. Then, the indoor operation communication unit 31 of the indoor unit 3a sends a signal including the abnormality code data to the outdoor unit 2a via the operation communication line 200a (FIGS. 7 and 8 (11)).
　室外機２ａの室外側操作用通信部２２は、室内機３ａからの異常コードのデータを含む信号を受信する。そして、室外機２ａの室外側管理用通信部２１は、管理用通信線１００を介して、受信した異常コードのデータを含む信号を、システムコントローラ１に送る（図７および図８（１２））。 The outdoor operation communication unit 22 of the outdoor unit 2a receives a signal including the abnormality code data from the indoor unit 3a.
