　フラグ設定部２３２は、広域接続端末情報管理部２３１に新たな広域接続端末情報が記憶されると、当該広域接続端末情報が「接続確認」のための広域接続登録要求により記憶されたものであるか、「通常利用」のための広域接続登録要求により記憶されたものであるかを判断する。そして、「接続確認」のための広域接続登録要求により記憶されたものであると判断すると、広域接続端末情報管理部２３１内の該当する広域接続端末情報に“ ON ”フラグを設定する。その後、フラグ設定部２３２は、有効期間監視部２３３から有効期間経過通知が出力されると、該当する広域接続端末情報のフラグを“ OFF ”に切り替える。 When new wide area connection terminal information is stored in the wide area connection terminal information management unit 231, the flag setting unit 232 stores the wide area connection terminal information by a wide area connection registration request for “connection confirmation”. Or whether it is stored by the wide area connection registration request for “normal use”. When it is determined that the information is stored by the wide area connection registration request for “connection confirmation”, the “ON” flag is set in the corresponding wide area terminal information in the wide area terminal information management unit 231. Thereafter, when the effective period monitoring notification is output from the effective period monitoring unit 233, the flag setting unit 232 switches the flag of the corresponding wide area terminal information to “OFF”.
　有効期間監視部２３３は、広域接続端末情報管理部２３１に記憶された広域接続端末情報に“ ON ”フラグが設定されると、時刻管理部２１で取得された現在日時情報から、有効期間情報記憶部２２３に記憶された情報に基づいて、有効期間が終了する有効期間終了日時を算出する。そして、フラグが“ ON ”の間、現在日時が、算出した有効期間終了日時を経過したか否かを監視する。有効期間監視部２３３は、現在日時が、算出した有効期間終了日時を経過したと判断すると、有効期間経過通知を生成して出力する。 When the “ON” flag is set in the wide area connection terminal information stored in the wide area connection terminal information management unit 231, the effective period monitoring unit 233 stores the effective period information from the current date and time information acquired by the time management unit 21. Based on the information stored in the unit 223, the effective period end date and time at which the effective period ends is calculated. While the flag is “ON”, it is monitored whether or not the current date and time has passed the calculated effective period end date and time. If the validity period monitoring unit 233 determines that the current date / time has passed the calculated validity period end date / time, the validity period monitoring unit 233 generates and outputs a validity period elapse notification.
　運転制御部２３４は、携帯端末８０から、無線ＬＡＮ回線７０を介して、またはキャリア網６０および広域ネットワーク４０を介して、空調機１０の運転に関する操作情報を取得すると、取得した操作情報に基づき、必要に応じて空調機通信部２４１を介して空調機１０に運転操作指示を送信し、空調機１０の運転を制御する。 When the operation control unit 234 acquires the operation information regarding the operation of the air conditioner 10 from the mobile terminal 80 via the wireless LAN line 70 or the carrier network 60 and the wide area network 40, the operation control unit 234, based on the acquired operation information, If necessary, an operation instruction is transmitted to the air conditioner 10 via the air conditioner communication unit 241 to control the operation of the air conditioner 10.

A description will be given of the operation when performing the connection confirmation work whether or not it is possible. It is assumed that an air conditioning management application is installed in the mobile terminal 80 in advance.
　まず、施工者は、携帯端末８０において空調管理用アプリケーションを１回目に利用する際に、利用登録操作を行う。利用登録は、広域ネットワーク４０経由では実行できない。そこで、携帯端末８０を、無線ＬＡＮ回線７０を介してルータ３０に直接接続させ、当該接続を用いて空調管理制御装置２０と携帯端末８０に関する情報を送受信することで、以後は広域ネットワーク４０からも利用可能となるよう登録を行う。 First, the contractor performs a use registration operation when using the air conditioning management application for the first time on the portable terminal 80. Usage registration cannot be performed via the wide area network 40. Therefore, the mobile terminal 80 is directly connected to the router 30 via the wireless LAN line 70, and information relating to the air conditioning management control device 20 and the mobile terminal 80 is transmitted and received using the connection. Register to be available.
　携帯端末８０では、利用登録操作により、当該空調管理用アプリケーションが「通常利用」されるか、あるいは「接続確認」のために利用されるかを示す利用目的が、下記の認識処理(1)～(3)のいずれかにより認識される。 In the portable terminal 80, the usage purpose indicating whether the application for air conditioning management is “normally used” or used for “connection confirmation” by the usage registration operation is the following recognition processing (1) to Recognized by either (3).
　［利用目的の認識処理(1)］
　空調管理用アプリケーションが１回目に起動された際に、図３に示すようなモード選択画面８１が携帯端末８０の表示面上に表示される。表示面はタッチ操作可能な画面となっている。このモード選択画面８１には、空調管理用アプリケーションを「通常利用」することを選択するための通常利用ボタン８１ａ、および「接続確認」のために利用することを選択するための接続確認ボタン８１ｂが表示されている。 [Recognition process for usage purpose (1)]

The mode selection screen 81 includes a normal use button 81a for selecting “normal use” of the air conditioning management application, and a connection confirmation button 81b for selecting use for “connection confirmation”. It is displayed.
　そして、モード選択画面８１上でユーザがいずれかのボタンをタッチ操作することで、空調機アプリケーションにおいて、当該空調管理用アプリケーションが「通常利用」されるか、あるいは「接続確認」のために利用されるかが認識される。 Then, when the user touches any button on the mode selection screen 81, the air conditioning application is “normally used” or used for “connection confirmation” in the air conditioner application. Is recognized.
　［利用目的の認識処理(2)］
　空調管理用アプリケーションが１回目に起動された際に、図４に示すようなログイン画面８２が携帯端末８０に表示される。このログイン画面８２には、ユーザＩＤを入力するためのスペース８２ａおよびログインボタン８２ｂが表示されている。 [Recognition process for usage purpose (2)]
When the air conditioning management application is activated for the first time, a login screen 82 as shown in FIG. On this login screen 82, a space 82a for inputting a user ID and a login button 82b are displayed.
　空調機管理用アプリケーションには、施工者を識別するためのユーザＩＤが予め保持されており、ログイン画面８２のスペース８２ａに施工者が当該ユーザＩＤを入力してログインボタン８２ｂをタッチ操作すると、空調機管理用アプリケーションにより、操作しているユーザが施工者であると判断され、「接続確認」のために利用されると認識される。 In the air conditioner management application, a user ID for identifying the contractor is stored in advance. When the contractor inputs the user ID in the space 82a of the login screen 82 and touches the login button 82b, the air conditioning is performed. It is recognized by the machine management application that the user who is operating is a contractor and is used for “connection confirmation”.
　また、ログイン画面８２上で、施工者を識別するためのユーザＩＤ以外のユーザＩＤが入力されたときには、「通常利用」されると認識される。 Also, when a user ID other than the user ID for identifying the contractor is entered on the login screen 82, it is recognized as “normal use”.
　当該ログイン画面８２において、さらにパスワードを入力させることで、ユーザの識別精度をより高くするようにしてもよい。 The user's identification accuracy may be further increased by further inputting a password on the login screen 82.
　［利用目的の認識処理(3)］
　利用目的の認識処理(3)を実行する携帯端末８０Ａについて、図５を参照して説明する。当該携帯端末８０Ａは、タッチ操作可能な画面で構成される入出力部８３と、インストールされた空調管理用アプリケーション８４と、当該携帯端末８０Ａの識別情報を記憶する識別情報記憶部８５と、広域ネットワーク４０および無線ＬＡＮ回線７０を介した通信を行う通信制御部８６とを有する。また、当該携帯端末８０Ａが施工者の携帯端末である場合には、通常、空調機点検用アプリケーション８７がインストールされている。 [Recognition process for usage purpose (3)]
A mobile terminal 80A that executes the purpose-of-use recognition process (3) will be described with reference to FIG. The mobile terminal 80A includes an input / output unit 83 configured with a touch operable screen, an installed air conditioning management application 84, an identification information storage unit 85 that stores identification information of the mobile terminal 80A, and a wide area network. 40 and a communication control unit 86 that performs communication via the wireless LAN line 70. When the portable terminal 80A is a contractor's portable terminal, an air conditioner inspection application 87 is usually installed.
　この空調機点検用アプリケーション８７は、例えば、近距離無線通信（ＮＦＣ）で利用されるＮＦＣタグを備えた空調機１０の室外機から、非接触でＮＦＣタグの読み取りおよび書き込みを実行可能にするものである。この空調機点検用アプリケーションを携帯端末８０Ａにインストールすることで、空調機１０が通電状態になくても、携帯端末８０Ａにおいて空調機１０から、室外機の各種情報や、接続された室内機の設定値及びセンサ情報が取得可能になる。施工者は空調機１０の据付後に動作確認を行うため、施工者の携帯端末８０Ａには、空調機点検用アプリケーションプログラムがインストールされている。一方、空調機１０の一般ユーザ（使用者）は、このような特殊なアプリケーションを携帯端末にインストールしていることはない。 This air conditioner inspection application 87 enables non-contact reading and writing of an NFC tag from an outdoor unit of the air conditioner 10 equipped with an NFC tag used for short-range wireless communication (NFC), for example. It is. By installing this air conditioner inspection application on the mobile terminal 80A, even if the air conditioner 10 is not energized, various information on the outdoor units and settings of the connected indoor units are set from the air conditioner 10 in the mobile terminal 80A. Values and sensor information can be acquired. Since the installer checks the operation after installing the air conditioner 10, an application program for checking the air conditioner is installed in the portable terminal 80A of the installer. On the other hand, a general user (user) of the air conditioner 10 does not install such a special application on the mobile terminal.
　この携帯端末８０Ａにおいて、入出力部８３での操作に基づいて空調管理用アプリケーション８４が起動され、広域接続登録要求を行う際、すなわち、広域ネットワークを介して接続するための登録を要求する際、には、空調管理用アプリケーション８４の判断部８４１において、当該携帯端末８０Ａに空調機点検用アプリケーション８７のプログラムがインストールされているか否かが判断される。判断の結果、当該携帯端末８０Ａに所定の空調機点検用アプリケーション８７がインストールされていたときには、処理部８４２により、操作しているユーザが施工者であると判断され、「接続確認」のために利用されると認識される。一方、判断部８４１において、当該携帯端末８０Ａに空調機点検用アプリケーション８７のプログラムがインストールされていないと判断されると、処理部８４２により、操作しているユーザは、一般の空調機の利用者であると判断され、「通常利用」目的と認識される。 In this portable terminal 80A, when the air conditioning management application 84 is activated based on an operation at the input / output unit 83 and makes a wide area connection registration request, that is, when requesting registration for connection via a wide area network, In the air conditioning management application 84, the determination unit 841 determines whether or not the air conditioner inspection application 87 program is installed in the portable terminal 80A. As a result of the determination, when the predetermined air conditioner inspection application 87 is installed in the portable terminal 80A, the processing unit 842 determines that the operating user is the builder, and performs “connection confirmation”. Recognized as being used. On the other hand, when the determination unit 841 determines that the program for the air conditioner inspection application 87 is not installed in the portable terminal 80A, the user operating the general air conditioner user is determined by the processing unit 842. Therefore, it is recognized as a “normal use” purpose.
　上述した(1)～(3)いずれかの認識処理により、空調機管理用アプリケーションが「接続確認」のために利用されることが認識されると、「接続確認」のための登録を指定する情報、および当該携帯端末８０の識別情報を含む広域接続登録要求が、無線ＬＡＮ回線７０、およびルータ３０を介して空調管理制御装置２０に送信される。例えば、図５の携帯端末８０Ａにおいては、処理部８４２において空調機管理用アプリケーション８４が「接続確認」のために利用されることが認識されると、「接続確認」のための登録を指定する情報、および識別情報記憶部８５に記憶された当該携帯端末８０Ａの識別情報を含む広域接続登録要求が、通信制御部８６から無線ＬＡＮ回線７０、およびルータ３０を介して空調管理制御装置２０に送信される。なお、無線ＬＡＮ回線７０は、建物Ａ内の範囲でしか通信が確立されないため、建物Ａの外部からの登録はできない。このため、第三者が外部から登録することはできず、セキュリティが担保されている。 If any of the above recognition processes (1) to (3) recognizes that the air conditioning unit management application is used for "connection confirmation", specify registration for "connection confirmation" A wide area connection registration request including information and identification information of the mobile terminal 80 is transmitted to the air conditioning management control device 20 via the wireless LAN line 70 and the router 30. For example, in the portable terminal 80A of FIG. 5, when the processing unit 842 recognizes that the air conditioner management application 84 is used for “connection confirmation”, it designates registration for “connection confirmation”. A wide area connection registration request including information and the identification information of the portable terminal 80A stored in the identification information storage unit 85 is transmitted from the communication control unit 86 to the air conditioning management control device 20 via the wireless LAN line 70 and the router 30. Is done. The wireless LAN line 70 cannot be registered from outside the building A because communication is established only within the range within the building A. For this reason, a third party cannot register from the outside, and security is ensured.
　空調管理制御装置２０において、広域接続登録要求が取得されたときに実行される処理について、図６のフローチャートを参照して説明する。 Processing executed when the air conditioning management control device 20 acquires a wide area connection registration request will be described with reference to the flowchart of FIG.
　空調管理制御装置２０では、広域接続登録要求が取得されると（Ｓ１の「YES」）、制御部２３の広域接続端末情報管理部２３１により、当該要求に含まれる携帯端末８０の識別情報が広域接続端末情報として広域接続端末情報記憶部２２２に記憶されるとともに、ルータ３０および広域ネットワーク４０を介してクラウドサーバ５０に送信される（Ｓ２）。クラウドサーバ５０では、空調管理制御装置２０から送信された広域接続端末情報が、空調管理制御装置２０への接続を許可する端末の情報として記憶される。 In the air conditioning management control device 20, when the wide area connection registration request is acquired (“YES” in S1), the wide area connection terminal information management unit 231 of the control unit 23 sets the identification information of the portable terminal 80 included in the request to the wide area. While being stored in the wide area connection terminal information storage unit 222 as connection terminal information, it is transmitted to the cloud server 50 via the router 30 and the wide area network 40 (S2). In the cloud server 50, the wide area connection terminal information transmitted from the air conditioning management control device 20 is stored as information on a terminal that permits connection to the air conditioning management control device 20.
　以降は、携帯端末８０において、空調管理用アプリケーション８４が起動され、広域ネットワーク４０を介して空調管理制御装置２０に接続させるための操作が行われると、まず、携帯端末８０はクラウドサーバ５０にアクセスする。そして、クラウドサーバ５０において、記憶された広域接続端末情報に基づいて接続が許可され、空調管理制御装置２０への接続が確立される。携帯端末８０から広域ネットワーク４０を介して空調管理制御装置２０への接続が確立されると、建物Ａ外の遠隔地からでも、携帯端末８０において図７に示すような操作画面により、空調機１０の運転操作が可能になる。図７に示す空調管理用アプリケーションの一画面では、１階のダイニングの空調機が２４℃に設定されていることが示されており、さらに詳細設定を行う画面を表示させることで、設定温度、風向、風速等の設定を変更することができる。 Thereafter, when the air conditioning management application 84 is activated on the mobile terminal 80 and an operation for connecting to the air conditioning management control device 20 is performed via the wide area network 40, the mobile terminal 80 first accesses the cloud server 50. To do. Then, in the cloud server 50, the connection is permitted based on the stored wide area connection terminal information, and the connection to the air conditioning management control device 20 is established. When the connection from the portable terminal 80 to the air conditioning management control device 20 is established via the wide area network 40, the air conditioner 10 can be operated from the remote location outside the building A by the operation screen as shown in FIG. Can be operated. One screen of the air conditioning management application shown in FIG. 7 shows that the air conditioner of the dining room on the first floor is set to 24 ° C. Further, by displaying a screen for further detailed setting, the set temperature, Settings such as wind direction and wind speed can be changed.
　従来は、「接続確認」の操作が終了した後、施工者が携帯端末８０を用いて、空調管理制御装置２０の広域接続端末情報記憶部２２２に記憶された携帯端末８０に関する広域接続端末情報を削除するための操作を行う必要がある。この情報を削除する操作をし忘れると、以降も、携帯端末８０から広域ネットワーク４０を介して空調機１０の操作が可能になってしまい、セキュリティ上の問題が発生してしまう。 Conventionally, after the operation of “connection confirmation” is completed, the contractor uses the mobile terminal 80 to store the wide area connection terminal information related to the mobile terminal 80 stored in the wide area connection terminal information storage unit 222 of the air conditioning management control device 20. It is necessary to perform an operation for deletion. If the user forgets to delete the information, the air conditioner 10 can be operated from the portable terminal 80 via the wide area network 40, and a security problem occurs.
　そこで、本実施形態では、図６のフローチャートに示すように空調管理制御装置２０において広域接続登録要求が取得されたとき（Ｓ１の「YES」からＳ２が完了）、に、以下の処理が実行される。まず、「接続確認」のための広域接続登録がなされた場合を説明する。制御部２３のフラグ設定部２３２により、当該要求が「接続確認」のための広域接続登録要求であるかまたは、「通常利用」のための広域接続登録要求であるかが判断される（Ｓ３）。ここでは、取得した広域接続登録要求に「接続確認」のための登録を指定する情報が含まれているため、「接続確認」のための広域接続登録要求であると判断される（Ｓ３の「YES」）。 Therefore, in the present embodiment, as shown in the flowchart of FIG. 6, when a wide area connection registration request is acquired in the air conditioning management control device 20 (S2 is completed from “YES” in S1), the following processing is executed. The First, a case where wide area connection registration for “connection confirmation” is performed will be described. The flag setting unit 232 of the control unit 23 determines whether the request is a wide area connection registration request for “connection confirmation” or a wide area connection registration request for “normal use” (S3). . Here, since the information for specifying registration for “connection confirmation” is included in the acquired wide area connection registration request, it is determined that the request is a wide area connection registration request for “connection confirmation” (“ YES ").
　取得した広域接続登録要求が「接続確認」のためのものであると判断されると、フラグ設定部２３２により、広域接続端末情報管理部２３１内の該当する広域接続端末情報に“ ON ”フラグが設定される（Ｓ４）。該当する広域接続端末情報に“ ON ”フラグが設定されると、有効期間監視部２３３により、時刻管理部２１で計時された現在日時情報から、有効期間情報記憶部２２３に記憶された情報に基づいて、有効期間が終了する有効期間終了日時が算出される（Ｓ５）。この有効期間は、施工者が設置工事の作業を確実に終えることが可能な時間になるように設定される。例えば、現在日時情報で取得された日付の次の日の開始時刻0:00が、有効期間終了日時として算出される。 When it is determined that the acquired wide area connection registration request is for “connection confirmation”, the flag setting unit 232 sets the “ON” flag in the corresponding wide area connection terminal information in the wide area connection terminal information management unit 231. It is set (S4). When the “ON” flag is set in the corresponding wide area connection terminal information, based on the information stored in the effective period information storage unit 223 from the current date and time information measured by the time management unit 21 by the effective period monitoring unit 233. Thus, the effective period end date and time at which the effective period ends is calculated (S5). This effective period is set to be a time during which the installer can reliably finish the installation work. For example, the start time 0:00 of the next day after the date acquired by the current date information is calculated as the valid period end date.
　以降、有効期間監視部２３３により、現在日時が、算出された有効期間終了日時を経過したか否かが監視される。そして、時刻管理部２１における現在日時が有効期間終了日時を経過したと判断されると（Ｓ６の「YES」）、有効期間経過通知が生成されて出力される。なお、フラグが“ ON ”の間は、現在日時が有効期間終了日時を経過するまで（Ｓ６の「NO」の場合）、この判断は繰り返される。 Thereafter, the validity period monitoring unit 233 monitors whether or not the current date and time has passed the calculated validity period end date and time. When it is determined that the current date and time in the time management unit 21 has passed the valid period end date and time (“YES” in S6), a valid period elapsed notification is generated and output. While the flag is “が ON”, this determination is repeated until the current date / time passes the valid period end date / time (in the case of “NO” in S6).
　有効期間監視部２３３により有効期間経過通知が出力されると、フラグ設定部２３２により、該当する広域接続端末情報のフラグが“ OFF ”に切り替えられる（Ｓ７）。フラグが“ OFF ”に切り替えられると、広域接続端末情報管理部２３１により、広域接続端末情報記憶部２２２内の該当する広域接続端末情報が削除されるとともに、クラウドサーバ５０に対し、同様に当該端末情報を削除する指示が送信される（Ｓ８）。 When the effective period monitoring unit 233 outputs the effective period elapse notification, the flag setting unit 232 switches the corresponding wide area terminal information flag to “OFF” (S7). When the flag is switched to “OFF”, the wide-area connection terminal information management unit 231 deletes the corresponding wide-area connection terminal information in the wide-area connection terminal information storage unit 222, and the terminal similarly for the cloud server 50. An instruction to delete information is transmitted (S8).
　広域接続端末情報記憶部２２２およびクラウドサーバ５０から携帯端末８０に関する広域接続端末情報が削除されることで、以降は施工者が携帯端末８０から広域ネットワーク４０を介して空調管理制御装置２０にアクセスすることが不可能になり、空調機１０の利用に関するセキュリティが確保される。 By deleting the wide area connection terminal information regarding the mobile terminal 80 from the wide area connection terminal information storage unit 222 and the cloud server 50, the installer subsequently accesses the air conditioning management control device 20 from the mobile terminal 80 via the wide area network 40. This makes it impossible to secure security related to the use of the air conditioner 10.
　一方、一般利用者の携帯端末Ｘで空調機管理用アプリケーションがインストールされ、初回起動時に利用登録操作が行われたときには、利用目的が「通常利用」として認識される。例えば、上述した［利用目的の認識処理(1)］により、携帯端末Ｘの表示面上に表示されたモード選択画面８１において、当該利用者が通常利用ボタン８１ａをタッチ操作することで、利用目的が「通常利用」として認識される。または、［利用目的の認識処理(2)］により、携帯端末Ｘの表示面上に表示されたログイン画面８２のスペース８２ａに、施工者を識別するために予め設定されたユーザＩＤ以外のユーザＩＤを当該利用者が入力してログインボタン８２ｂをタッチ操作することで、利用目的が「通常利用」として認識される。または、［利用目的の認識処理(3)］により、当該携帯端末Ｘには、施工者等の業者が利用する空調機点検用アプリケーションがインストールされていないと判断されることで、利用目的が「通常利用」として認識される。 On the other hand, when an application for air conditioner management is installed on the mobile terminal X of a general user and a use registration operation is performed at the first activation, the purpose of use is recognized as “normal use”. For example, when the user performs a touch operation on the normal use button 81a on the mode selection screen 81 displayed on the display surface of the mobile terminal X by the above-described [use purpose recognition process (1)], the use purpose is displayed. Is recognized as “normal use”. Alternatively, a user ID other than the user ID set in advance for identifying the contractor in the space 82a of the login screen 82 displayed on the display surface of the portable terminal X by [Recognition of Purpose of Use (2)]. Is input and the login button 82b is touched, and the purpose of use is recognized as “normal use”. Alternatively, by determining that the application for air conditioner inspection used by a contractor such as a contractor is not installed in the portable terminal X by the [use purpose recognition process (3)], the use purpose is “ It is recognized as “normal use”.
　利用目的が「通常利用」として認識されると、「通常利用」を指定する情報、および当該携帯端末Ｘの識別情報を含む広域接続登録要求が携帯端末Ｘの空調機管理用アプリケーションにより生成され、無線ＬＡＮ回線７０、およびルータ３０を介して空調管理制御装置２０に送信される。 When the purpose of use is recognized as “normal use”, a wide area connection registration request including information specifying “normal use” and identification information of the mobile terminal X is generated by the air conditioner management application of the mobile terminal X, It is transmitted to the air conditioning management control device 20 via the wireless LAN line 70 and the router 30.
　空調管理制御装置２０では、取得された広域接続登録要求に含まれる携帯端末Ｘの識別情報が広域接続端末情報として広域接続端末情報記憶部２２２に記憶されるとともに、ルータ３０を介してクラウドサーバ５０に送信され、以後、携帯端末Ｘから広域ネットワーク４０を介して空調管理制御装置２０へのアクセスが可能になる（Ｓ１、Ｓ２）。 In the air conditioning management control device 20, the identification information of the mobile terminal X included in the acquired wide area connection registration request is stored in the wide area connection terminal information storage unit 222 as the wide area connection terminal information, and the cloud server 50 is connected via the router 30. Thereafter, the portable terminal X can access the air conditioning management control device 20 via the wide area network 40 (S1, S2).
　ここで、空調管理制御装置２０において広域接続端末情報が取得されたときに、フラグ設定部２３２により、当該要求が「通常利用」のための広域接続登録要求であると判断され（Ｓ３の「NO」）、広域接続端末情報管理部２３１内の該当する広域接続端末情報のフラグは“ OFF ”状態が維持される（Ｓ９）。広域接続端末情報のフラグが“ OFF ”であることにより、広域接続端末情報記憶部２２２内の該当する広域接続端末情報に有効期間は設定されず、当該広域接続端末情報が削除されることがないため、以降、携帯端末Ｘから広域ネットワーク４０を介して空調管理制御装置２０へのアクセスが可能な状態が継続される。 Here, when the wide area connection terminal information is acquired in the air conditioning management control device 20, the flag setting unit 232 determines that the request is a wide area connection registration request for “normal use” (“NO” in S3). ]), The flag of the corresponding wide area connection terminal information in the wide area connection terminal information management unit 231 is maintained in the “OFF” state (S9). When the flag of the wide area connection terminal information is “OFF”, the validity period is not set in the corresponding wide area connection terminal information in the wide area connection terminal information storage unit 222, and the wide area connection terminal information is not deleted. Therefore, the state where the portable terminal X can access the air conditioning management control device 20 via the wide area network 40 is continued thereafter.
　以上の実施形態によれば、空調システムの設置工事を行う施工者が、自身の携帯端末から「接続確認」のために広域ネットワークを介して空調管理制御装置に接続可能な状態にした設定を、設置作業後に確実に接続不可能な状態にすることができる。 According to the above embodiment, the installer who performs the installation work of the air conditioning system is configured to be able to connect to the air conditioning management control device via the wide area network for "connection confirmation" from his portable terminal. It is possible to ensure that the connection is impossible after installation.
　上述した実施形態において、有効期間監視部２３３により、携帯端末の識別情報を記憶させた日付の次の日の開始時刻0:00を、有効期間終了日時として算出する場合について説明したが、携帯端末の識別情報を記憶させてから一定時間（例えば６時間）が経過した時点を、有効期間終了日時として算出するようにしてもよい。また、原則としては携帯端末の識別情報を記憶させた日付の次の日の開始時刻0:00を有効期間終了日時として算出し、算出した日時から次の日の開始時刻0:00までが所定時間（例えば６時間）に満たない場合は、携帯端末の識別情報を記憶させてから一定時間が経過した時点を有効期間終了日時として算出するようにしてもよい。 In the embodiment described above, the case has been described in which the effective period monitoring unit 233 calculates the start time 0:00 of the day after the date on which the identification information of the mobile terminal is stored as the effective period end date and time. The time when a certain time (for example, 6 hours) has passed since the identification information is stored may be calculated as the effective period end date and time. Also, as a general rule, the start time 0:00 of the next day after the date when the identification information of the mobile terminal is stored is calculated as the valid period end date and time, and the start time 0:00 of the next day is determined from the calculated date and time. If it is less than the time (for example, 6 hours), the time when a certain time has elapsed since the identification information of the mobile terminal was stored may be calculated as the effective period end date and time.
　なお、本実施形態においては、空調機１０と空調管理装置２０とを別体としたが、空調機１０内、一般的にはその室内機内に空調管理装置２０を組み込んで一体化しても良い。さらには、空調機１０内に無線ＬＡＮルータ３０までも組込み、空調管理装置２０と無線ＬＡＮルータ３０と空調機１０とを完全に一体化した機器とすることも可能である。 In the present embodiment, the air conditioner 10 and the air conditioning management device 20 are separated from each other. However, the air conditioning management device 20 may be integrated into the air conditioner 10, generally in the indoor unit. Further, even the wireless LAN router 30 can be incorporated into the air conditioner 10 so that the air conditioning management device 20, the wireless LAN router 30, and the air conditioner 10 are completely integrated.
　また、空調管理装置２０の機器全体を室内機１０に組み込むのではなく、空調管理装置２０が備える各種機能の一部のみを空調機１０に組み込んで、機能を分散配置させても良い。 Further, instead of incorporating the entire device of the air conditioning management device 20 into the indoor unit 10, only some of the various functions provided in the air conditioning management device 20 may be incorporated into the air conditioning device 10 to distribute the functions.
　以上、本発明の実施形態を説明したが、この実施形態は、例として提示したものであり、発明の範囲を限定することは意図していない。この新規な実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行うことができる。この実施形態やその変形は、発明の範囲や要旨に含まれるとともに、特許請求の範囲に記載された発明とその均等の範囲に含まれる。 As mentioned above, although embodiment of this invention was described, this embodiment is shown as an example and is not intending limiting the range of invention. The novel embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. This embodiment and its modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
