　本発明は、空調装置についてのメンテナンスの情報を提供する空調装置メンテナンスシステムに関する。 The present invention relates to an air conditioner maintenance system that provides maintenance information about an air conditioner.
　近年、ビルの大型化により１つのビルに設置される空調装置の台数が多くなっている。空調装置の設置台数に比例して空調装置に発生する異常の件数が増え、メンテナンスが必要な空調装置の台数も増加している。そのため、メンテナンスに必要な時間が長くなる傾向があり、メンテナンス性の向上が求められている。 In recent years, the number of air conditioners installed in one building has increased due to the increase in size of the building. The number of abnormalities occurring in the air conditioner is increasing in proportion to the number of installed air conditioners, and the number of air conditioners requiring maintenance is also increasing. Therefore, the time required for maintenance tends to be long, and improvement in maintainability is demanded.
　メンテナンス性の向上を図る方法の一例が、特許文献１に開示されている。特許文献１には、空調装置と、空調装置の状態を状態確認用の２次元コードに変換して表示するリモコンと、状態確認用の２次元コードを読み取って解析した結果を表示する情報端末装置とを有する空調装置メンテナンスシステムが開示されている。このシステムでは、情報端末装置は、空調装置に対するメンテナンスの項目が予め設定され、状態確認用の２次元コードの解析結果に基づくメンテナンスの項目に対応した指令用の２次元コードを表示する。リモコンは、情報端末装置に表示された指令用の２次元コードに対応するメンテナンス制御を実行する。これにより、ユーザはサポートセンターの力を借りなくても、一定範囲のメンテナンスが実行される。 An example of a method for improving maintenance performance is disclosed in Patent Document 1. Patent Document 1 discloses an air conditioner, a remote controller that converts and displays the state of the air conditioner into a two-dimensional code for state confirmation, and an information terminal device that displays a result of reading and analyzing the two-dimensional code for state confirmation. An air conditioner maintenance system is disclosed. In this system, the information terminal device has preset maintenance items for the air conditioner, and displays a command two-dimensional code corresponding to the maintenance item based on the analysis result of the state confirmation two-dimensional code. The remote controller executes maintenance control corresponding to the command two-dimensional code displayed on the information terminal device. As a result, the user can perform a certain range of maintenance without the assistance of the support center.
　一方、サポートセンターにメンテナンスを依頼するシステムの一例が特許文献２に開示されている。特許文献２に開示された空調装置メンテナンスシステムは、サービスコールボタンを備えたリモコンと、空気調和機の運転情報等の情報を記憶する空調集中管理装置と、空調集中管理装置とインターネットを介して接続された管理センタとを有する構成である。管理センタはメンテナンス会社またはサービス部門の情報を記憶するデータベースを有している。このシステムにおいて、機器に異常が発生したときにサービスコールボタンが押されると、空調集中管理装置は、運転情報等の情報を管理センタに送信し、管理センタは空調集中管理装置から受信した情報をメンテナンス会社またはサービス部門に送信する。 Meanwhile, an example of a system for requesting maintenance from a support center is disclosed in Patent Document 2. The air conditioner maintenance system disclosed in Patent Literature 2 is connected to a remote controller having a service call button, an air conditioning centralized management device that stores information such as operation information of the air conditioner, and an air conditioning centralized management device via the Internet. And a management center. The management center has a database for storing information on the maintenance company or service department.

The model data file 11 is a file that associates abnormality data and service data with the model information of the air conditioner as a key.
　図２は、図１に示したデータベースが保持する機種データファイルの一構成例を示す図である。図２に示すように、機種データファイル１１は、機種情報と、異常コードと、サービスデータ毎に異なる識別子であるサービスコードとを関連付けて保持している。機種データは、機種毎に、機種情報、異常コードおよびサービスコードを含むデータである。図２に示す例では、室内機Ａの機種データは、ＥＡ－０００１～７９９９の複数の異常コードと、ＳＡ００００、ＳＡ０００１およびＳＡ０００３の複数のサービスコードとを含む。この機種データには、１つの異常コードに注目すると、１つの異常コードに複数のサービスコードが関連付けられている。また、１つのサービスコードに注目すると、１つのサービスコードに複数の異常コードが関連付けられている。これは、１つの異常に関して、複数の原因が考えられ、複数の原因のそれぞれに対して対処方法があり得るからである。 FIG. 2 is a diagram showing a configuration example of a model data file held by the database shown in FIG. As shown in FIG. 2, the model data file 11 holds model information, an abnormality code, and a service code that is an identifier different for each service data in association with each other. The model data is data including model information, an abnormal code, and a service code for each model. In the example shown in FIG. 2, the model data of the indoor unit A includes a plurality of abnormality codes EA-0001 to 7999 and a plurality of service codes SA0000, SA0001, and SA0003. In this model data, when attention is paid to one abnormal code, a plurality of service codes are associated with one abnormal code. When attention is paid to one service code, a plurality of abnormal codes are associated with one service code. This is because there can be a plurality of causes for one abnormality, and there can be a countermeasure for each of the plurality of causes.
　１つの異常に対して、複数の原因のうち、発生頻度が統計的に算出されていれば、最も発生頻度が大きい原因の対処方法を作業者に提示した方がメンテナンスにかかる時間を短縮できる。そこで、機種データファイル１１では、１つの異常コードに対して、複数のサービスコードが考えられる場合、使用頻度の大きいサービスコードが少なくとも１つ関連付けられていてもよい。また、関連付けられるサービスコードの数は、１つに限らず、使用頻度が大きいものから順に予め決められた２以上の数であってもよい。 ∙ If the occurrence frequency is statistically calculated among a plurality of causes for one abnormality, the time required for maintenance can be shortened by presenting the worker with a countermeasure for the cause with the highest occurrence frequency. Therefore, in the model data file 11, when a plurality of service codes can be considered for one abnormal code, at least one service code having a high use frequency may be associated. Further, the number of service codes to be associated is not limited to one, and may be two or more numbers determined in advance in descending order of frequency of use.
　なお、１つの異常コードに関連付けられるサービスコードの数を使用頻度で絞る場合を説明したが、１つのサービスコードに対して複数の異常コードが関連付けられている場合に、１つのサービスコードに関連付けられる異常コードの数を使用頻度で絞ってもよい。また、異常コードに関連付けられるサービスコードの数が使用頻度で決定される場合で説明したが、その決定方法はサービスコードの使用頻度に限らない。さらに、機種データは、異常コードとサービスコードとを一対一で関連付けて保持していてもよい。 In addition, although the case where the number of service codes associated with one abnormal code is narrowed by the use frequency has been described, when a plurality of abnormal codes are associated with one service code, they are associated with one service code. The number of abnormal codes may be narrowed down by use frequency. Further, although the case where the number of service codes associated with the abnormal code is determined by the usage frequency has been described, the determination method is not limited to the usage frequency of the service code. Furthermore, the model data may hold the abnormality code and the service code in a one-to-one relationship.
　図３は、図１に示したデータベースが保持する異常データファイルの一構成例を示す図である。図３に示すように、異常データファイル１２は、複数の異常データが列挙された構成である。異常データは、異常コードと、異常内容の詳細情報と、異常の原因と、原因に対する対処方法との情報を含む。異常データファイル１２は、異常コードをキーとして、メンテナンスに必要な情報を入手できる構成である。図３に示す異常データファイル１２は、室内機Ａの異常データファイルである。異常データファイル１２は、室外機、室内機、空調装置、換気装置および給湯装置等の空調機の機種毎にデータベース２０に保持される。 FIG. 3 is a diagram showing a configuration example of the abnormal data file held by the database shown in FIG. As shown in FIG. 3, the abnormal data file 12 has a configuration in which a plurality of abnormal data are listed. The abnormal data includes information on an abnormal code, detailed information on the content of the abnormality, a cause of the abnormality, and a coping method for the cause. The abnormal data file 12 is configured to obtain information necessary for maintenance using the abnormal code as a key. An abnormal data file 12 illustrated in FIG. 3 is an abnormal data file of the indoor unit A. The abnormal data file 12 is held in the database 20 for each type of air conditioner such as an outdoor unit, indoor unit, air conditioner, ventilator, and hot water supply device.
　図４は、図１に示したデータベースが保持するサービス情報の一構成例を示す図である。サービスデータファイル１３は、複数のサービスデータが列挙された構成である。サービスデータは、サービスコードと、異常発生時の詳細情報と、サービスが必要になった原因と、原因に対する対処方法との情報を含む。サービスデータファイル１３は、サービスコードをキーとして、必要なサービスの情報を入手できる構成である。図４に示すサービスデータファイル１３は、室内機Ａのサービスデータファイルである。サービスデータファイル１３は、室外機、室内機、空調装置、換気装置および給湯装置等の空調機の機種毎にデータベース２０に保持される。 FIG. 4 is a diagram showing a configuration example of service information held in the database shown in FIG. The service data file 13 has a configuration in which a plurality of service data are listed. The service data includes information on a service code, detailed information at the time of occurrence of an abnormality, a cause that the service is required, and a coping method for the cause. The service data file 13 is configured such that necessary service information can be obtained using a service code as a key. A service data file 13 shown in FIG. 4 is a service data file of the indoor unit A. The service data file 13 is held in the database 20 for each type of air conditioner such as an outdoor unit, indoor unit, air conditioner, ventilator, and hot water supply device.
　なお、作業者は情報端末８０、空調管理装置３０および情報処理装置５０のうち、いずれかの装置を介して、異常データファイル１２およびサービスデータファイル１３を編集することができる。編集方法の詳細は後述する。 The operator can edit the abnormal data file 12 and the service data file 13 via any one of the information terminal 80, the air conditioning management device 30, and the information processing device 50. Details of the editing method will be described later.
　通信管理部１６は、ＬＡＮインタフェース等のネットワークインタフェースおよび専用の通信用デバイスのようなハードウェアで構成される。通信管理部１６は、データベース２０のアクセス制限の機能を有する。アクセス制限の一例を説明する。通信管理部１６は、受信したデータに含まれる送信元の装置識別子を読み出す。通信管理部１６は、送信元の装置識別子が予め登録された装置識別子と一致するか否かを判定する。通信管理部１６は、送信元の装置識別子と登録された装置識別子が一致している場合、送信元はアクセスが許可された装置と認証し、受信したデータを制御部２１に転送する。一方、通信管理部１６は、送信元の装置識別子と登録された装置識別子が一致しない場合、送信元はアクセス制限の対象機器と認識し、受信したデータを制御部２１に転送しない。 The communication management unit 16 includes a network interface such as a LAN interface and hardware such as a dedicated communication device. The communication management unit 16 has a function of restricting access to the database 20. An example of access restriction will be described. The communication management unit 16 reads the transmission source device identifier included in the received data. The communication management unit 16 determines whether or not the transmission source device identifier matches a device identifier registered in advance. If the transmission source device identifier matches the registered device identifier, the communication management unit 16 authenticates the access permitted device and transfers the received data to the control unit 21. On the other hand, when the device identifier of the transmission source does not match the registered device identifier, the communication management unit 16 recognizes the transmission source as a device subject to access restriction and does not transfer the received data to the control unit 21.
　通信管理部１６は、データベース２０が保持するデータを要求するデータ取得指令を空調管理装置３０および情報端末８０から受信すると、送信元を認証した後、データ取得指令を制御部２１に転送する。通信管理部１６は、データ取得指令の応答としてデータを制御部２１から受け取ると、そのデータを送信元に返信する。また、通信管理部１６は、データベース２０が保持するデータの書き換え指示を含むデータ設定指令を空調管理装置３０および情報端末８０から受信すると、送信元を認証した後、データ設定指令を制御部２１に転送する。 When the communication management unit 16 receives a data acquisition command for requesting data held in the database 20 from the air conditioning management device 30 and the information terminal 80, the communication management unit 16 authenticates the transmission source and then transfers the data acquisition command to the control unit 21. When receiving data from the control unit 21 as a response to the data acquisition command, the communication management unit 16 returns the data to the transmission source. In addition, when the communication management unit 16 receives a data setting command including an instruction to rewrite data held in the database 20 from the air conditioning management device 30 and the information terminal 80, the communication management unit 16 authenticates the transmission source and then sends the data setting command to the control unit 21. Forward.
　なお、空調管理装置３０および情報端末８０の装置識別子は、制御部２１のメモリに予め登録されていてもよく、通信管理部１６に予め設けられたメモリに登録されていてもよい。また、アクセス制限解除の認証に、装置識別子の代わりに、作業者毎に予め決められたユーザＩＤおよびパスワードを用いてもよい。また、アクセス制限の機能を制御部２１が備えていてもよい。 The device identifiers of the air conditioning management device 30 and the information terminal 80 may be registered in advance in the memory of the control unit 21 or may be registered in a memory provided in advance in the communication management unit 16. In addition, a user ID and a password determined in advance for each worker may be used for authentication for access restriction release instead of the device identifier. Further, the control unit 21 may have an access restriction function.
　制御部２１は、データベース２０が保持するデータから適切なデータを検索する検索処理部１８と、検索したデータを表示するツールを情報端末８０に提供する表示アプリケーション部１７と、各データの内容を編集するツールを情報端末８０に提供する設定アプリケーション部１９とを有する。制御部２１は、プログラムを記憶するメモリと、プログラムにしたがって処理を実行するＣＰＵとを有する。ＣＰＵがプログラムを実行することで、表示アプリケーション部１７、検索処理部１８、および設定アプリケーション部１９がデータ保持装置１０に構成される。 The control unit 21 includes a search processing unit 18 that searches for appropriate data from data held in the database 20, a display application unit 17 that provides a tool for displaying the searched data to the information terminal 80, and edits the contents of each data And a setting application unit 19 that provides the information terminal 80 with a tool to be used. The control unit 21 includes a memory that stores a program and a CPU that executes processing according to the program. As the CPU executes the program, the display application unit 17, the search processing unit 18, and the setting application unit 19 are configured in the data holding device 10.
　検索処理部１８は、空調管理装置３０および情報端末８０から受信するデータ取得指令に基づいて、機種データファイル１１、異常データファイル１２およびサービスデータファイル１３から適切なデータを取得する。検索処理部１８は、例えば、データ取得指令に含まれる機種情報を基に機種データファイル１１から異常コードを特定し、異常コードに関連付けられた、異常内容、異常の原因、および異常の対処方法を異常データファイル１２から取得する。また、検索処理部１８は、データ取得指令に含まれる機種情報を基に、機種データファイル１１からサービスコードを特定し、サービスコードに関連付けられた、異常発生時の詳細情報と、異常の原因と、サービスの内容である対処方法とをサービスデータファイル１３から取得してもよい。さらに、検索処理部１８は、データ取得指令に機種情報および異常コードが含まれていれば、機種情報および異常コードをキーとして機種データファイル１１を参照してサービスコードを特定し、特定したサービスコードに対応するサービスデータをサービスデータファイル１３から取得してもよい。 The search processing unit 18 acquires appropriate data from the model data file 11, the abnormal data file 12, and the service data file 13 based on the data acquisition command received from the air conditioning management device 30 and the information terminal 80. For example, the search processing unit 18 identifies an abnormal code from the model data file 11 on the basis of the model information included in the data acquisition command, and describes the abnormality content, the cause of the abnormality, and the countermeasure method for the abnormality associated with the abnormal code. Obtained from the abnormal data file 12. In addition, the search processing unit 18 specifies a service code from the model data file 11 based on the model information included in the data acquisition command, detailed information when the abnormality occurs, the cause of the abnormality, associated with the service code, The coping method that is the content of the service may be acquired from the service data file 13. Further, if the data acquisition command includes model information and an abnormal code, the search processing unit 18 refers to the model data file 11 using the model information and the abnormal code as a key, identifies the service code, and identifies the identified service code. Service data corresponding to may be obtained from the service data file 13.
　表示アプリケーション部１７は、通信管理部１６を介して情報端末８０からデータ取得指令を受信すると、データ取得指令に基づいて検索処理部１８が検索したデータを情報端末８０の表示部８２に表示させる。また、表示アプリケーション部１７は、通信管理部１６を介して空調管理装置３０からデータ取得指令を受信すると、データ取得指令に基づいて検索処理部１８が検索したデータを空調管理装置３０の表示部３３に表示させる。 When the display application unit 17 receives a data acquisition command from the information terminal 80 via the communication management unit 16, the display application unit 17 displays the data searched by the search processing unit 18 based on the data acquisition command on the display unit 82 of the information terminal 80. When the display application unit 17 receives a data acquisition command from the air conditioning management device 30 via the communication management unit 16, the display unit 33 of the air conditioning management device 30 stores the data searched by the search processing unit 18 based on the data acquisition command. To display.
　設定アプリケーション部１９は、通信管理部１６を介して情報端末８０からデータ設定指令を受信すると、データ設定指令に基づいて、機種データファイル１１、異常データファイル１２およびサービスデータファイル１３のうち、関連するファイルの内容を書き替える。また、設定アプリケーション部１９は、通信管理部１６を介して空調管理装置３０からデータ設定指令を受信すると、データ設定指令に基づいて、機種データファイル１１、異常データファイル１２およびサービスデータファイル１３のうち、関連するファイルの内容を書き替える。 When the setting application unit 19 receives a data setting command from the information terminal 80 via the communication management unit 16, the setting application unit 19 relates to the model data file 11, the abnormal data file 12, and the service data file 13 based on the data setting command. Rewrite the contents of the file. In addition, when the setting application unit 19 receives a data setting command from the air conditioning management device 30 via the communication management unit 16, the setting application unit 19 among the model data file 11, the abnormal data file 12, and the service data file 13 based on the data setting command. Rewrite the contents of related files.
　なお、図１を参照して、表示アプリケーション部１７、設定アプリケーション部１９および検索処理部１８はＣＰＵがプログラムを実行することで構成される場合で説明したが、これらの機能を実行する専用の回路デバイスなどのハードウェアで構成されてもよい。検索処理部１８は、データ保持装置１０に格納された独立したアプリケーションソフトウェアプログラムをＣＰＵが実行することで構成されてもよい。この場合、このアプリケーションソフトウェアプログラムがデータ保持装置１０内に予め格納されていてもよい。また、表示アプリケーション部１７についても同様に、データ保持装置１０内に格納された独立したアプリケーションソフトウェアプログラムをＣＰＵが実行することで構成されてもよい。この場合、このアプリケーションソフトウェアプログラムは、データ保持装置１０内に予め格納されていてもよい。 1, the display application unit 17, the setting application unit 19, and the search processing unit 18 have been described in the case where the CPU is configured to execute a program. However, a dedicated circuit that executes these functions is described. It may be configured by hardware such as a device. The search processing unit 18 may be configured by the CPU executing an independent application software program stored in the data holding device 10. In this case, the application software program may be stored in the data holding device 10 in advance. Similarly, the display application unit 17 may be configured by the CPU executing an independent application software program stored in the data holding device 10. In this case, the application software program may be stored in advance in the data holding device 10.
　情報端末８０は、通信管理部８１と、表示部８２と、入力部８３と、これらの構成を制御する制御部８４とを有する。制御部８４は、プログラムを記憶するメモリと、プログラムにしたがって処理を実行するＣＰＵとを有する。情報端末８０は、例えば、スマートフォンおよびタブレット等の携帯型情報端末である。制御部８４は、通信管理部８１を介してデータ取得指令およびデータ設定指令をデータ保持装置１０に送信する際、情報端末８０の装置識別子を、これらの指令に添付して送信する。 The information terminal 80 includes a communication management unit 81, a display unit 82, an input unit 83, and a control unit 84 that controls these configurations. The control unit 84 includes a memory that stores a program and a CPU that executes processing according to the program. The information terminal 80 is a portable information terminal such as a smartphone and a tablet, for example. When transmitting the data acquisition command and the data setting command to the data holding device 10 via the communication management unit 81, the control unit 84 transmits the device identifier of the information terminal 80 attached to these commands.
　制御部８４は、データ保持装置１０のデータベース２０が保持するデータを、表示アプリケーション部１７および検索処理部１８を介して、表示部８２に表示させる機能を有する。また、制御部８４は、データ保持装置１０のデータベース２０が保持するデータを、設定アプリケーション部１９を介して、編集する機能を有する。そのため、作業者は情報端末８０を操作して、データベース２０が保持するデータを設定アプリケーション部１９を介して書き換えられる。また、作業者は情報端末８０を操作して、データベース２０が保持するデータを表示アプリケーション部１７を介して表示部８２に表示させることができる。制御部８４はデータベース２０が保持するデータを表示および編集するためのソフトウェアプログラムを保持する必要がなく、例えば、ブラウザを保持していればよい。この場合、表示アプリケーション部１７が表示部８２にデータを表示させる処理は、制御部２１がブラウザに表示させるデータを情報端末８０に送信する処理に相当すると考えることができる。 The control unit 84 has a function of causing the display unit 82 to display the data held in the database 20 of the data holding device 10 via the display application unit 17 and the search processing unit 18. In addition, the control unit 84 has a function of editing data held in the database 20 of the data holding device 10 via the setting application unit 19. Therefore, the operator operates the information terminal 80 to rewrite the data held in the database 20 via the setting application unit 19. In addition, the operator can operate the information terminal 80 to display data held in the database 20 on the display unit 82 via the display application unit 17. The control unit 84 does not need to hold a software program for displaying and editing data held in the database 20, and may hold a browser, for example. In this case, the process in which the display application unit 17 displays data on the display unit 82 can be considered to correspond to the process in which the control unit 21 transmits data to be displayed on the browser to the information terminal 80.
　情報処理装置５０は、通信管理部５１と、表示部５２と、入力部５３と、これらの構成を制御する制御部５４とを有する。情報処理装置５０は、例えば、デスクトップ型のパーソナルコンピュータである。制御部５４は、プログラムを記憶するメモリと、プログラムにしたがって処理を実行するＣＰＵとを有する。作業者は、情報処理装置５０を操作して、プライベートネットワーク９１および空調管理装置３０を介して、室外機６０－１、６０－２および室内機７０－１～７０－４から運転データを取得し、これらの空調機の運転状態を監視する。また、作業者は、情報処理装置５０に操作データを入力することで、情報処理装置５０からプライベートネットワーク９１および空調管理装置３０を介して、室外機６０－１、６０－２および室内機７０－１～７０－４を操作する。 The information processing apparatus 50 includes a communication management unit 51, a display unit 52, an input unit 53, and a control unit 54 that controls these configurations. The information processing apparatus 50 is, for example, a desktop personal computer. The control unit 54 includes a memory that stores a program and a CPU that executes processing according to the program. The operator operates the information processing device 50 to obtain operation data from the outdoor units 60-1 and 60-2 and the indoor units 70-1 to 70-4 via the private network 91 and the air conditioning management device 30. Monitor the operating status of these air conditioners. In addition, the operator inputs operation data to the information processing apparatus 50, whereby the outdoor units 60-1 and 60-2 and the indoor unit 70- are connected from the information processing apparatus 50 via the private network 91 and the air conditioning management apparatus 30. 1 to 70-4 are operated.
　情報処理装置５０はデータベース２０のアクセス制限の対象であるが、空調管理装置３０はデータベース２０のアクセス制限の対象になっていない。そのため、作業者は、情報処理装置５０を操作して、空調管理装置３０経由で、データ保持装置１０のデータベース２０が保持するデータを、情報処理装置５０に取得させることができる。また、作業者は、情報処理装置５０を操作して、空調管理装置３０経由で、データ保持装置１０のデータベース２０が保持するデータを編集することができる。 The information processing apparatus 50 is a target of access restriction of the database 20, but the air conditioning management apparatus 30 is not a target of access restriction of the database 20. Therefore, the operator can cause the information processing device 50 to acquire the data held in the database 20 of the data holding device 10 via the air conditioning management device 30 by operating the information processing device 50. Further, the operator can edit the data held in the database 20 of the data holding device 10 via the air conditioning management device 30 by operating the information processing device 50.
　なお、情報処理装置５０は、情報端末８０と同様に、携帯型の情報端末であってもよい。情報処理装置５０は、例えば、ノート型のパーソナルコンピュータであってもよい。また、情報端末８０および情報処理装置５０は、データベース２０が保持するデータを表示および編集するためのソフトウェアプログラムを保持していてもよい。この場合、制御部２１に表示アプリケーション部１７および設定アプリケーション部１９が設けられていなくてもよい。 Note that the information processing apparatus 50 may be a portable information terminal, like the information terminal 80. The information processing apparatus 50 may be a notebook personal computer, for example. Further, the information terminal 80 and the information processing apparatus 50 may hold a software program for displaying and editing data held in the database 20. In this case, the display application unit 17 and the setting application unit 19 may not be provided in the control unit 21.
　次に、本実施の形態１における空調装置メンテナンスシステムの動作を説明する。図５は、本発明の実施の形態１における空調装置メンテナンスシステムの動作手順を示すシーケンス図である。 Next, the operation of the air conditioner maintenance system in the first embodiment will be described. FIG. 5 is a sequence diagram showing an operation procedure of the air conditioner maintenance system according to Embodiment 1 of the present invention.
　作業者が空調管理装置３０の表示部３３を見ながら、情報端末８０を操作して機種情報と異常コードとを入力すると、情報端末８０は、機種情報および異常コードを含むデータ取得指令をデータ保持装置１０に送信する（ステップＳ１０１）。データ保持装置１０の通信管理部１６は、情報端末８０からデータ取得指令を受信すると、送信元の情報端末８０がアクセス制限の対象であるか否かを判定する。通信管理部１６は、情報端末８０がアクセス制限の対象でないと判定すると、データ取得指令を検索処理部１８に転送する。 When an operator operates the information terminal 80 and inputs model information and an abnormal code while looking at the display unit 33 of the air conditioning management device 30, the information terminal 80 holds a data acquisition command including the model information and the abnormal code as data. It transmits to the apparatus 10 (step S101). When receiving the data acquisition command from the information terminal 80, the communication management unit 16 of the data holding device 10 determines whether or not the transmission source information terminal 80 is an access restriction target. If the communication management unit 16 determines that the information terminal 80 is not subject to access restriction, the communication management unit 16 transfers a data acquisition command to the search processing unit 18.
　検索処理部１８は、通信管理部１６からデータ取得指令を受け取ると、データ取得指令から機種情報および異常コードを読み出す。そして、検索処理部１８は、機種情報および異常コードをキーとして機種データファイル１１を検索し（ステップＳ１０２）、サービスコードを特定する。続いて、検索処理部１８は、特定したサービスコードに対応するサービスデータをサービスデータファイル１３から読み出す。その後、検索処理部１８は、読み出したサービスデータを情報端末８０に表示させることを表示アプリケーション部１７に指示する。表示アプリケーション部１７は、検索処理部１８からサービスデータを受け取ると、通信管理部１６を介してサービスデータを情報端末８０の表示部８２に表示させる（ステップＳ１０３）。情報端末８０は表示部８２にサービスデータを表示する（ステップＳ１０４）。 When the search processing unit 18 receives the data acquisition command from the communication management unit 16, the search processing unit 18 reads the model information and the error code from the data acquisition command. Then, the search processing unit 18 searches the model data file 11 using the model information and the abnormal code as keys (step S102), and identifies the service code. Subsequently, the search processing unit 18 reads out service data corresponding to the identified service code from the service data file 13. Thereafter, the search processing unit 18 instructs the display application unit 17 to display the read service data on the information terminal 80. When receiving the service data from the search processing unit 18, the display application unit 17 displays the service data on the display unit 82 of the information terminal 80 via the communication management unit 16 (step S103). The information terminal 80 displays the service data on the display unit 82 (step S104).
　ステップＳ１０２において、検索処理部１８は、異常データファイル１２から異常コードに対応する異常データを読み出し、読み出した異常データをサービスデータに添付して表示アプリケーション部１７に渡してもよい。この場合、表示アプリケーション部１７は、異常データおよびサービスデータを情報端末８０の表示部８２に表示させる。この場合、作業者は、表示部８２が表示する異常データの情報を参照することで、異常発生の原因をより詳細に確認することができる。 In step S102, the search processing unit 18 may read the abnormal data corresponding to the abnormal code from the abnormal data file 12, and attach the read abnormal data to the service data to the display application unit 17. In this case, the display application unit 17 displays the abnormal data and service data on the display unit 82 of the information terminal 80. In this case, the operator can confirm the cause of the abnormality in more detail by referring to the information of the abnormality data displayed on the display unit 82.
　ここで、図６を参照して、検索処理部１８のステップＳ１０２における処理を説明する。図６は、図１に示した検索処理部が実行する検索処理の一例を示す図である。検索処理部１８は、室内機Ａおよび異常コードＥＡ－０００２を含むデータ取得指令を通信管理部１６から受け取ると、機種データファイル１１を参照し、室内機Ａおよび異常コードＥＡ－０００２に関連付けられたサービスコードＳＢ－０００３を読み出す。そして、検索処理部１８は、サービスデータファイルＳＢからサービスコードＳＢ－０００３のサービスデータを読み出す。このとき、検索処理部１８は、サービスデータと一緒に異常データを表示アプリケーション部１７に渡してもよい。この場合、作業者は、表示部８２が表示する異常データの情報から「温度異常」が異常発生の原因であることがわかる。 Here, the process in step S102 of the search processing unit 18 will be described with reference to FIG. FIG. 6 is a diagram illustrating an example of search processing executed by the search processing unit illustrated in FIG. When the search processing unit 18 receives a data acquisition command including the indoor unit A and the abnormality code EA-0002 from the communication management unit 16, the search processing unit 18 refers to the model data file 11 and associates the indoor unit A with the abnormal code EA-0002. Read service code SB-0003. Then, the search processing unit 18 reads the service data of the service code SB-0003 from the service data file SB. At this time, the search processing unit 18 may pass the abnormal data together with the service data to the display application unit 17. In this case, the operator can understand from the information of the abnormal data displayed on the display unit 82 that the “temperature abnormality” is the cause of the abnormality.
　このようにして、作業者は、情報端末８０を操作して機種情報および異常コードを入力することで、機種情報および異常コードをキーとして、データベース２０から異常データおよびサービスデータを取得できる。そのため、作業者は、異常が発生した空調機について、異常の原因および対処方法を含むメンテナンス情報を効率良く取得できる。 In this way, the operator can acquire the abnormal data and the service data from the database 20 using the model information and the abnormal code as keys by operating the information terminal 80 and inputting the model information and the abnormal code. Therefore, the operator can efficiently acquire maintenance information including the cause of the abnormality and a countermeasure for the air conditioner in which the abnormality has occurred.
　また、作業者は、情報処理装置５０を操作して、情報処理装置５０および空調管理装置３０を介してサービスデータをデータ保持装置１０から取得してもよい。具体的には、作業者は、情報処理装置５０に機種情報および異常コードを入力すると、情報処理装置５０は、データ取得指令を空調管理装置３０を介してデータ保持装置１０に送信する。空調管理装置３０はデータベース２０のアクセス制限を受けないので、データ保持装置１０は、空調管理装置３０から受信したデータ取得指令を受け付ける。そして、データ保持装置１０は、データ取得指令に基づいてサービスデータをデータベース２０から取得すると、サービスデータを空調管理装置３０の表示部３３に表示させる。空調管理装置３０は表示部３３に表示されるサービスデータを情報処理装置５０に転送して表示部５２に表示させる。 Further, the operator may acquire service data from the data holding device 10 through the information processing device 50 and the air conditioning management device 30 by operating the information processing device 50. Specifically, when the worker inputs model information and an abnormality code to the information processing device 50, the information processing device 50 transmits a data acquisition command to the data holding device 10 via the air conditioning management device 30. Since the air conditioning management device 30 is not subject to the access restriction of the database 20, the data holding device 10 receives the data acquisition command received from the air conditioning management device 30. When the data holding device 10 acquires the service data from the database 20 based on the data acquisition command, the data holding device 10 displays the service data on the display unit 33 of the air conditioning management device 30. The air conditioning management device 30 transfers the service data displayed on the display unit 33 to the information processing device 50 and causes the display unit 52 to display the service data.
　この場合、作業者は、ネットワーク９０に接続されていない情報処理装置５０がデータベース２０へのアクセスが制限される装置であっても、情報処理装置５０を操作して空調管理装置３０を経由して、メンテナンスに関する情報をデータベース２０から取得することができる。その結果、作業者のメンテナンスの利便性が向上する。 In this case, even if the information processing device 50 that is not connected to the network 90 is a device in which access to the database 20 is restricted, the worker operates the information processing device 50 and passes through the air conditioning management device 30. Information regarding maintenance can be acquired from the database 20. As a result, the convenience of maintenance for the operator is improved.
　次に、作業者が情報端末８０を操作してデータベース２０が保持するデータを編集する場合について説明する。図７は、本発明の実施の形態１における空調装置メンテナンスシステムにおいて、データベースが保持するデータを編集する場合の動作手順を示すシーケンス図である。ここでは、編集対象のファイルがサービスデータファイル１３であるものとする。また、アクセス制限に関する説明を省略する。 Next, a case where the operator operates the information terminal 80 to edit data held in the database 20 will be described.

When the control unit 21 of the data holding device 10 receives the display request signal, the display application unit 17 displays the service data file 13 on the display unit 82 of the information terminal 80.
　作業者が表示部８２に表示されたサービスデータファイル１３を見ながら、サービスの内容を書き換える指示を情報端末８０に入力すると、情報端末８０は、書き換え指示の情報を含むデータ設定指令をデータ保持装置１０に送信する（ステップＳ２０１）。データ保持装置１０の制御部２１がデータ設定指令を受け取ると、設定アプリケーション部１９が、データ設定指令に含まれる書き換え指示にしたがって、サービスデータファイル１３を編集する（ステップＳ２０２）。続いて、表示アプリケーション部１７は、編集後のサービスデータファイル１３を情報端末８０の表示部８２に表示させる（ステップＳ２０３）。情報端末８０は表示部８２に、編集後のサービスデータファイル１３を表示する（ステップＳ２０４）。 When an operator inputs an instruction to rewrite service contents to the information terminal 80 while viewing the service data file 13 displayed on the display unit 82, the information terminal 80 sends a data setting command including information on the rewrite instruction to the data holding device. 10 (step S201). When the control unit 21 of the data holding device 10 receives the data setting command, the setting application unit 19 edits the service data file 13 according to the rewrite instruction included in the data setting command (step S202). Subsequently, the display application unit 17 displays the edited service data file 13 on the display unit 82 of the information terminal 80 (step S203). The information terminal 80 displays the edited service data file 13 on the display unit 82 (step S204).
　このようにして、作業者は、情報端末８０を操作して、データ保持装置１０のデータベース２０が保持するデータを編集することができる。作業者は、情報処理装置５０を操作して、空調管理装置３０を介して、データ保持装置１０のデータベース２０が保持するデータを編集してもよい。 In this way, the operator can edit the data held in the database 20 of the data holding device 10 by operating the information terminal 80.

The work history is information on the history of operation when an abnormality occurs in the air conditioner. Specifically, the work history includes model information, an operation when the air conditioner of the model information has an abnormality, and information on the time of each operation. In the arbitrary information, work information when an abnormality is dealt with is registered. When registering work history data, the worker can arbitrarily enter work information in the optional information column.

　このようにして、作業者は、情報端末８０を操作して、データ保持装置１０ｂのデータベース２０が保持する作業履歴ファイル１５を用いて、メンテナンス対象の空調機と同じ機種の空調機に過去に異常が発生したときの履歴を参考にすることができる。その結果、作業者は、メンテナンス対象の空調機に今後発生する現象を把握し、事前に対処できる。また、作業履歴データの任意情報に作業情報が登録されていれば、作業者は、異常に対してどのような対処が行われたかを参考にできる。作業者は、情報処理装置５０を操作して、空調管理装置３０を介して、データ保持装置１０ｂのデータベース２０が保持する作業履歴ファイル１５を利用し、メンテナンス情報を取得してもよい。 In this manner, the operator operates the information terminal 80 and uses the work history file 15 held in the database 20 of the data holding device 10b to detect abnormalities in the past in the air conditioner of the same model as the maintenance target air conditioner. You can refer to the history when this occurred. As a result, the operator can grasp the phenomenon that will occur in the future in the air conditioner to be maintained, and can cope with it in advance. Further, if the work information is registered in the arbitrary information of the work history data, the worker can refer to what measures have been taken for the abnormality. The operator may operate the information processing apparatus 50 and use the work history file 15 held in the database 20 of the data holding apparatus 10b via the air conditioning management apparatus 30 to acquire maintenance information.
　近年、ビル等の建物に入ることが厳重に管理されていることが多く、このような建物に設置された空調装置も通信接続が厳重に管理された環境に置かれている。このような環境に設置された空調装置のメンテナンスにおいて、作業者がメンテナンス用の情報処理装置または情報端末を空調管理装置にネットワークを介して接続させることが、セキュリティ上困難な場合がある。そのため、作業者は、メンテナンス時の情報と空調管理装置の状態とを照合して、メンテナンス情報を収集することが困難であった。 Recently, entry into buildings such as buildings is often strictly controlled, and air conditioners installed in such buildings are also placed in environments where communication connections are strictly controlled. In maintenance of an air conditioner installed in such an environment, it may be difficult in terms of security for an operator to connect an information processing apparatus or information terminal for maintenance to the air conditioning management apparatus via a network. Therefore, it is difficult for an operator to collect maintenance information by collating information during maintenance with the state of the air conditioning management device.
　これに対して、本実施の形態３では、データ保持装置１０ｂの制御部２１は、空調管理装置３０から作業履歴データを受信する度に、受信した作業履歴データを建物単位およびフロア単位で仕分けして、データベース２０が保持する作業履歴ファイル１５に格納する。データ保持装置１０ｂは空調管理装置３０に対してアクセス制限をかけていないので、空調管理装置３０は、自装置が管理する空調機に異常が発生する度に作成した作業履歴データを、データ保持装置１０ｂに順次登録することができる。そのため、データ保持装置１０ｂは、最新の作業履歴の情報を容易に蓄積することができ、メンテナンス情報を自動的に更新できる。 In contrast, in the third embodiment, the control unit 21 of the data holding device 10b sorts the received work history data in units of buildings and floors every time work history data is received from the air conditioning management device 30. And stored in the work history file 15 held by the database 20. Since the data holding device 10b does not restrict access to the air conditioning management device 30, the air conditioning management device 30 stores the work history data created every time an abnormality occurs in the air conditioner managed by the data holding device 10b. 10b can be sequentially registered. Therefore, the data holding device 10b can easily accumulate the latest work history information and can automatically update the maintenance information.
　また、本実施の形態３では、制御部２１が、機種情報と機種情報の機種に異常が発生したときの動作の履歴の情報とを含む作業履歴データを建物単位およびフロア単位に保持する作業履歴ファイル１５をメンテナンス情報として用いることで、作業者は、メンテナンス対象の空調機と同じ機種の空調機に過去に異常が発生したときの履歴を参考にすることができる。その結果、作業者は、メンテナンス対象の空調機に今後発生する現象を把握し、事前に対処できる。 In the third embodiment, the control unit 21 holds work history data including model information and history information of operations when an abnormality occurs in the model of the model information in the unit of building and floor. By using the file 15 as maintenance information, the operator can refer to the history when an abnormality has occurred in the past in the same type of air conditioner as the maintenance target air conditioner. As a result, the operator can grasp the phenomenon that will occur in the future in the air conditioner to be maintained, and can cope with it in advance.
　なお、実施の形態３では、作業履歴ファイル１５が実施の形態２で説明したデータ保持装置１０ａに設けられる場合で説明したが、作業履歴ファイル１５が実施の形態１で説明したデータ保持装置１０に設けられてもよい。 In the third embodiment, the case where the work history file 15 is provided in the data holding device 10a described in the second embodiment has been described. However, the work history file 15 is added to the data holding device 10 described in the first embodiment. It may be provided.
　また、上述した実施の形態１～３で説明したデータ保持装置が実行する処理を、コンピュータおよびサーバ装置を含む情報処理装置に実行させるために、その処理の手順をプログラムに記述したものを記録媒体に格納してもよい。また、そのプログラムを記憶する情報処理装置がネットワークを介して他の情報処理装置にそのプログラムを提供してもよい。 In addition, in order to cause the information processing apparatus including the computer and the server apparatus to execute the process executed by the data holding apparatus described in the first to third embodiments, a recording medium in which the procedure of the process is described in a program is recorded. May be stored. An information processing apparatus that stores the program may provide the program to another information processing apparatus via a network.
