Description

警報装置、および情報処理システムAlarm device and information processing system
　本開示は、警報装置、および情報処理システムに関する。 This disclosure relates to an alarm device and an information processing system.
　従来、ガスメータ等の自動検針システムとしては、公衆電話回線を利用する双方向方式が知られている。例えば、センタ装置と各需要家に取り付けられた自動検針用のガスメータとの間を端末網制御装置付の公衆電話回線で接続し、センタ装置から電話回線を通じてガスメータによる検針情報を読み込む。また、ガスメータの検針情報とともに、ガスメータの安全情報をセンタ装置に通報する技術も提案されている。 Conventionally, as an automatic meter reading system such as a gas meter, a bidirectional system using a public telephone line is known. For example, a center meter and a gas meter for automatic meter reading attached to each consumer are connected by a public telephone line with a terminal network control device, and meter reading information by the gas meter is read from the center device through the telephone line. In addition, a technique has been proposed in which gas meter safety information is reported to the center device together with gas meter reading information.
　例えば、特開２００８－３５４２３号公報（特許文献１）は、警報装置からの警報電文を無線受信し、該無線受信した警報電文に基づいて警報状態を端末網制御手段及び公衆電話回線を介してセンタ装置に通報する警報通報装置を開示している。この警報通報装置は、警報電文の無線受信に応じ、検針機能付ガスメータによる検針情報とともに当該ガスメータに係わる安全監視情報をセンタ装置に伝送するために、安全監視データフラグ一覧中の未使用フラグのうちの、受信した警報電文に対して予め対応付けられたフラグをセットし、端末網制御手段に対する起動要求信号の送信後に端末網制御手段から受信する要求電文に応じ、セットされたフラグを含む応答電文を送信する。 For example, Japanese Patent Laid-Open No. 2008-35423 (Patent Document 1) wirelessly receives an alarm message from an alarm device, and based on the alarm message received wirelessly, the alarm state is transmitted via a terminal network control means and a public telephone line. An alarm reporting device for reporting to the center device is disclosed. In response to the wireless reception of the alarm message, this alarm reporting device transmits the safety monitoring information related to the gas meter together with the meter reading information by the gas meter with meter reading function to the center device, among the unused flags in the safety monitoring data flag list. A response message including a flag that is set in accordance with a request message received from the terminal network control means after the activation request signal is transmitted to the terminal network control means after setting a flag associated with the received alarm message in advance. Send.

　典型的には、ガスメータによる検針情報は、顧客ごとに予め指定された検針日に定期的にセンタ装置に向けて送信される。しかしながら、この指定された検針日が、顧客の要望により集中してしまった場合には、センタ装置側の処理の高負荷あるいは回線混雑等による通信上の障害の発生のため、実際の検針日が翌日以降の所定日にずれてしまう。そうすると、検針期間が、前回検針日から当該所定日までの期間となってしまい顧客サービス上好ましくない。特許文献１は、上記課題を解決するための技術を何ら教示ないし示唆していない。 Typically, meter reading information by a gas meter is periodically transmitted to the center device on the meter reading date designated in advance for each customer. However, if the specified meter reading date is concentrated due to customer requests, the actual meter reading date may be due to a high processing load on the center side or a communication failure due to line congestion. It will shift to the predetermined day after the next day. Then, the meter reading period becomes a period from the previous meter reading date to the predetermined date, which is not preferable for customer service. Patent Document 1 does not teach or suggest any technique for solving the above problems.

　＜処理手順＞
　警報装置１０における各種処理の手順について説明する。 <Processing procedure>
Various processing procedures in the alarm device 10 will be described.
　（検針情報の送信方式）
　図３は、実施の形態１に従う検針情報の送信方式を説明するためのフローチャートである。ここでは、警報装置１０がセンタサーバ５０に指定検針日の検針情報を送信する方式について説明する。 (Transmission method of meter reading information)
FIG. 3 is a flowchart for illustrating a method for transmitting meter reading information according to the first embodiment. Here, a method in which the alarm device 10 transmits meter reading information on the designated meter reading date to the center server 50 will be described.
　図３を参照して、警報装置１０のプロセッサ１０２は、予め指定された検針日（指定検針日）に基づく検針タイミングが到来したか否かを判断する（ステップＳ１０）。 Referring to FIG. 3, the processor 102 of the alarm device 10 determines whether or not the meter reading timing based on a pre-designated meter reading date (designated meter reading date) has arrived (step S10).
　具体的には、プロセッサ１０２は、ＬＴＥモジュール１１２およびネットワーク４０を介して、センタサーバ５０から指定検針日の検針指示を受信した場合に当該検針タイミングが到来したと判断する。あるいは、プロセッサ１０２は、不揮発性メモリ１０６に予め記憶された指定検針日と現在日時とを比較することにより、当該検針タイミングが到来したか否かを判断してもよい。 Specifically, the processor 102 determines that the meter reading timing has arrived when a meter reading instruction is received from the center server 50 via the LTE module 112 and the network 40. Alternatively, the processor 102 may determine whether or not the meter reading timing has arrived by comparing the designated meter reading date stored in advance in the nonvolatile memory 106 with the current date and time.
　プロセッサ１０２は、ガスメータ２０Ａに対して、現時点での検針情報を警報装置１０に送信するように指示する（ステップＳ１２）。具体的には、プロセッサ１０２は、Ｂｌｕｅｔｏｏｔｈモジュール１１１を介して、当該指示を示す指示情報をガスメータ２０Ａに送信する。 The processor 102 instructs the gas meter 20A to transmit the current meter reading information to the alarm device 10 (step S12). Specifically, the processor 102 transmits instruction information indicating the instruction to the gas meter 20A via the Bluetooth module 111.
　プロセッサ１０２は、Ｂｌｕｅｔｏｏｔｈモジュール１１１を介して、現時点での検針情報をガスメータ２０Ａから受信する（ステップＳ１４）。プロセッサ１０２は、受信した検針情報を指定検針日の検針情報としてメモリ（例えば、不揮発性メモリ１０６）に記憶する（ステップＳ１６）。 The processor 102 receives the current meter reading information from the gas meter 20A via the Bluetooth module 111 (step S14). The processor 102 stores the received meter reading information in a memory (for example, the nonvolatile memory 106) as meter reading information on the designated meter reading date (step S16).
　プロセッサ１０２は、ＬＴＥモジュール１１２を介して、メモリに記憶されている指定検針日の検針情報をセンタサーバ５０に送信する（ステップＳ１８）。続いて、プロセッサ１０２は、当該検針情報のセンタサーバ５０への送信が成功したか否かを判断する（ステップＳ２０）。 The processor 102 transmits the meter reading information of the designated meter reading date stored in the memory to the center server 50 via the LTE module 112 (step S18). Subsequently, the processor 102 determines whether or not the meter reading information has been successfully transmitted to the center server 50 (step S20).
　例えば、プロセッサ１０２は、検針情報の送信を行なった場合に、一定時間が経過してもセンタサーバ５０からの応答を受信しない場合（すなわち、タイムアウトが発生した場合）、検針情報がセンタサーバ５０に到達しなかった（すなわち、送信が失敗した）と判断する。そうではない場合には、プロセッサ１０２は、検針情報の送信が成功したと判断する。 For example, when transmitting the meter reading information and the processor 102 does not receive a response from the center server 50 even after a predetermined time has elapsed (that is, when a time-out occurs), the meter reading information is sent to the center server 50. It is determined that it did not reach (that is, transmission failed). Otherwise, the processor 102 determines that the meter reading information has been successfully transmitted.
　当該検針情報の送信が成功した場合には（ステップＳ２０においてＹＥＳ）、プロセッサ１０２は処理を終了する。当該検針情報の送信が失敗した場合には（ステップＳ２０においてＮＯ）、プロセッサ１０２は、当該検針情報の送信が失敗してから所定期間（例えば、一日）が経過したか否かを判断する（ステップＳ２２）。所定時間が経過していない場合には（ステップＳ２２においてＮＯ）、プロセッサ１０２はステップＳ２２の処理を実行する。 If the meter reading information has been successfully transmitted (YES in step S20), the processor 102 ends the process. If transmission of the meter reading information has failed (NO in step S20), the processor 102 determines whether or not a predetermined period (for example, one day) has elapsed since the transmission of the meter reading information has failed (for example, one day). Step S22). If the predetermined time has not elapsed (NO in step S22), processor 102 executes the process of step S22.
　所定時間が経過した場合には（ステップＳ２２においてＹＥＳ）、プロセッサ１０２は、ステップＳ１８の処理を実行する。すなわち、プロセッサ１０２は、メモリに記憶されている指定検針日の検針情報をセンタサーバ５０に再送信する。 If the predetermined time has elapsed (YES in step S22), the processor 102 executes the process of step S18. That is, the processor 102 retransmits the meter reading information stored in the memory to the center server 50.
　上記によると、警報装置１０は、ガスメータ２０Ａから取得した指定検針日の検針情報をメモリに記憶しておく。そして、センタサーバ５０側の処理の高負荷あるいは回線混雑等による通信上の障害が発生し、仮に指定検針日に検針情報を送信できなかった場合であっても、警報装置１０は、センタサーバ５０と通信可能になった時点で、メモリに記憶された指定検針日の検針情報をセンタサーバ５０に送信する。これにより、検針期間がずれることがないため、顧客サービスを向上させることができる。 According to the above, the alarm device 10 stores the meter reading information on the designated meter reading date acquired from the gas meter 20A in the memory. Even if a communication failure occurs due to a high processing load on the center server 50 side or a line congestion, and the meter reading information cannot be transmitted on the designated meter reading date, the alarm device 10 is connected to the center server 50. When the communication becomes possible, the meter reading information of the designated meter reading date stored in the memory is transmitted to the center server 50. Thereby, since a meter-reading period does not shift, customer service can be improved.
　（遮断情報の送信方式）
　図４は、実施の形態１に従う遮断情報の送信方式を説明するためのフローチャートである。ここでは、警報装置１０が対象ガスを検出した場合に、センタサーバ５０にガスの遮断情報を送信する方式について説明する。 (Sending information transmission method)
FIG. 4 is a flowchart for illustrating a blocking information transmission method according to the first embodiment. Here, a method for transmitting gas cutoff information to the center server 50 when the alarm device 10 detects the target gas will be described.
　図４を参照して、警報装置１０のプロセッサ１０２は、ガスセンサ１３１を介して、住宅２０１の屋内において対象ガスを検出したか否かを判断する（ステップＳ３０）。対象ガスが検出されていない場合には（ステップＳ３０においてＮＯ）、プロセッサ１０２はステップＳ３０の処理を実行する。 Referring to FIG. 4, the processor 102 of the alarm device 10 determines whether or not the target gas has been detected inside the house 201 via the gas sensor 131 (step S30). If the target gas has not been detected (NO in step S30), processor 102 executes the process of step S30.
　対象ガスが検出された場合には（ステップＳ３０においてＹＥＳ）、プロセッサ１０２は、Ｂｌｕｅｔｏｏｔｈモジュール１１１を介して、対象ガスが検出されたことを示すガス検出情報をガスメータ２０Ａに送信する（ステップＳ３２）。ガスメータ２０Ａは、ガス検出情報を受信すると、遮断弁を遮断してガス容器からのガス供給を停止する。そして、ガスメータ２０Ａは、Ｂｌｕｔｏｏｔｈモジュールを介して、当該遮断が実行されたことを示す遮断情報を警報装置１０に送信する。 If the target gas is detected (YES in step S30), the processor 102 transmits gas detection information indicating that the target gas has been detected to the gas meter 20A via the Bluetooth module 111 (step S32). When the gas meter 20A receives the gas detection information, the gas meter 20A shuts off the shutoff valve and stops the gas supply from the gas container. Then, the gas meter 20 </ b> A transmits cutoff information indicating that the cutoff has been executed to the alarm device 10 via the Bluetooth module.
　プロセッサ１０２は、Ｂｌｕｅｔｏｏｔｈモジュール１１１を介して、ガスメータ２０Ａから遮断情報を受信して（ステップＳ３４）、当該遮断情報を現在日時と関連付けてメモリに記憶する（ステップＳ３６）。具体的には、プロセッサ１０２は、遮断情報と、遮断が実行された遮断日時とを含む遮断関連情報をメモリに記憶する。 The processor 102 receives the cutoff information from the gas meter 20A via the Bluetooth module 111 (step S34), and stores the cutoff information in association with the current date and time (step S36). Specifically, the processor 102 stores, in a memory, block-related information including the block information and the block date and time when the block was executed.
　プロセッサ１０２は、ＬＴＥモジュール１１２を介して、メモリに記憶された遮断関連情報をセンタサーバ５０に送信する（ステップＳ３８）。続いて、プロセッサ１０２は、遮断関連情報のセンタサーバ５０への送信が成功したか否かを判断する（ステップＳ４０）。 The processor 102 transmits the block-related information stored in the memory to the center server 50 via the LTE module 112 (step S38). Subsequently, the processor 102 determines whether or not the blocking-related information has been successfully transmitted to the center server 50 (step S40).
　遮断関連情報の送信が成功した場合には（ステップＳ４０においてＹＥＳ）、プロセッサ１０２は処理を終了する。遮断関連情報の送信が失敗した場合には（ステップＳ４０においてＮＯ）、プロセッサ１０２は、遮断関連情報の送信が失敗してから所定期間が経過したか否かを判断する（ステップＳ４２）。所定期間が経過していない場合には（ステップＳ４２においてＮＯ）、プロセッサ１０２はステップＳ４２の処理を実行する。 If the transmission of the blocking-related information is successful (YES in step S40), the processor 102 ends the process. If transmission of the blocking related information has failed (NO in step S40), the processor 102 determines whether or not a predetermined period has elapsed since the transmission of the blocking related information has failed (step S42). If the predetermined period has not elapsed (NO in step S42), processor 102 executes the process of step S42.
　所定期間が経過した場合には（ステップＳ４２においてＹＥＳ）、プロセッサ１０２は、ステップＳ３８の処理を実行する。すなわち、プロセッサ１０２は、メモリに記憶されている遮断関連情報をセンタサーバ５０に再送信する。 If the predetermined period has elapsed (YES in step S42), the processor 102 executes the process of step S38. That is, the processor 102 retransmits the cutoff related information stored in the memory to the center server 50.
　上記によると、警報装置１０は、ガスメータ２０Ａによって遮断弁がいつ遮断されたのかを示す遮断関連情報をメモリに記憶しておく。そして、災害等の発生によりセンタサーバ５０との通信が不能となり遮断関連情報が送信できなかった場合であっても、警報装置１０は、センタサーバ５０との通信可能になった時点で遮断関連情報をセンタサーバ５０に送信する。これにより、センタサーバ５０側で、どの時点でガスが遮断されたのかを精度よく把握することができる。 According to the above, the alarm device 10 stores in the memory the shutoff related information indicating when the shutoff valve is shut off by the gas meter 20A. Even when the communication with the center server 50 becomes impossible due to the occurrence of a disaster or the like, and the interruption-related information cannot be transmitted, the alarm device 10 is notified when the communication with the center server 50 becomes possible.

The communication control unit 313 is mainly realized by the processor 102 and the communication unit 110.
　ある局面では、通信制御部３１３は、第２通信モジュールを介して、記憶部３０３に記憶された指定検針日の検針情報をセンタサーバ５０に送信する。通信制御部３１３は、指定検針日の検針情報のセンタサーバ５０への送信が失敗した場合、当該送信が失敗してから所定期間経過後（例えば、１日後）に、指定検針日の検針情報をセンタサーバ５０に再度送信する。なお、通信制御部３１３は、指定検針日の検針情報のセンタサーバ５０への送信が成功した場合、記憶部３０３に記憶された指定検針日の検針情報を送信成功直後、あるいは送信成功から一定期間経過後（例えば、数か月後）に削除してもよい。これにより、記憶部３０３の容量を効率的に利用することができる。 In one aspect, the communication control unit 313 transmits the meter reading information on the designated meter reading date stored in the storage unit 303 to the center server 50 via the second communication module. When the transmission of the meter reading information on the designated meter reading date to the center server 50 fails, the communication control unit 313 displays the meter reading information on the designated meter reading date after a predetermined period (for example, one day) after the transmission fails. It transmits again to the center server 50. When the transmission of the meter reading information on the designated meter reading date to the center server 50 is successful, the communication control unit 313 displays the meter reading information stored in the storage unit 303 immediately after the successful transmission or for a certain period from the successful transmission.

To do. As a result, the user can directly notify the center server 50 of an emergency situation.
　装置間通信部３１５は、警報装置１１と無線通信を行なう。典型的には、装置間通信部３１５は、第３通信モジュール（例えば、Ｗｉ－ＳＵＮモジュール１１３）を介して、警報装置１１と無線通信を行なう。例えば、装置間通信部３１５は、各種情報（例えば、検針情報、遮断関連情報、撮像情報および緊急情報等）を警報装置１１から受信する。通信制御部３１３は、第２通信モジュールを介して、装置間通信部３１５により取得された各種情報をセンタサーバ５０に送信する。 The inter-device communication unit 315 performs wireless communication with the alarm device 11.

For example, the inter-device communication unit 315 receives various information (for example, meter-reading information, blockage-related information, imaging information, emergency information, and the like) from the alarm device 11. The communication control unit 313 transmits various information acquired by the inter-device communication unit 315 to the center server 50 via the second communication module.
　ここで、警報装置１１は、上述した警報装置１０の機能構成のうち、通信制御部３１３以外の各機能構成（すなわち、検針情報取得部３０１、記憶部３０３、ガス検出部３０５、遮断情報取得部３０７、撮像情報取得部３０９、操作部３１１、装置間通信部３１５）を有する。具体的には、警報装置１１では、指定検針日の検針情報、遮断関連情報、撮像情報、緊急指示情報等が取得される。そして、警報装置１１の装置間通信部は、Ｗｉ－ＳＵＮモジュールを介して、これらの情報を警報装置１０に送信する。 Here, the alarm device 11 is a functional configuration other than the communication control unit 313 (that is, the meter reading information acquisition unit 301, the storage unit 303, the gas detection unit 305, and the cutoff information acquisition unit) among the functional configurations of the alarm device 10 described above. 307, an imaging information acquisition unit 309, an operation unit 311 and an inter-device communication unit 315).

　＜利点＞
　実施の形態１によると、指定検針日に検針情報を送信できなかった場合であっても、警報装置１０とセンタサーバ５０との通信が可能になった時点でメモリに記憶された指定検針日の検針情報がセンタサーバ５０に送信されるため、検針期間がずれることがなく、顧客サービスを向上させることができる。 <Advantages>
According to the first embodiment, even when the meter reading information cannot be transmitted on the designated meter reading date, the designated meter reading date stored in the memory at the time when the alarm device 10 and the center server 50 can communicate with each other becomes available. Since the meter reading information is transmitted to the center server 50, the meter reading period is not shifted and the customer service can be improved.
　ガス遮断時において遮断情報を送信できなかった場合であっても、警報装置１０とセンタサーバ５０との通信が可能になった時点でメモリに記憶された遮断関連情報をセンタサーバ５０に送信できる。これにより、センタサーバ５０側でガス遮断がいつ行われたのかをより精度よく把握できる。 Even if the shutoff information cannot be transmitted at the time of gas shutoff, the shutoff related information stored in the memory can be sent to the center server 50 when communication between the alarm device 10 and the center server 50 becomes possible. Thereby, it is possible to more accurately grasp when the gas shut-off is performed on the center server 50 side.
　公衆電話回線を通じてガスメータによる検針情報を読み込む方式において発生していた通話中に通信ができないという問題も解消される。また、通常時には商用電源からバッテリ１３６に充電され、停電時には代替電源としてバッテリ１３６が用いられるため、通信による警報装置１０の電力消耗を意識する必要がない。 The problem that communication cannot be performed during a call that occurred in the method of reading meter reading information by a gas meter through a public telephone line is also solved. In addition, since the battery 136 is charged from a commercial power supply during normal times and the battery 136 is used as an alternative power supply during a power failure, there is no need to be aware of the power consumption of the alarm device 10 due to communication.
　［実施の形態２］
　実施の形態２では、警報装置１０および複数の警報装置１１によるマルチホップ通信方式について説明する。上述したように、警報装置１０と警報装置１１とは、例えば、Ｗｉ－ＳＵＮの通信方式を用いて双方向通信可能に構成されている。Ｗｉ－ＳＵＮでは、複数の装置がバケツリレー方式でデータを中継し、遠隔地間を結ぶマルチホップ通信にも対応している。そのため、警報装置１０と複数の警報装置１１とはマルチホップ方式でデータを伝送することが可能である。 [Embodiment 2]
In the second embodiment, a multi-hop communication method using the alarm device 10 and the plurality of alarm devices 11 will be described. As described above, the alarm device 10 and the alarm device 11 are configured to be capable of bidirectional communication using, for example, a Wi-SUN communication method. In Wi-SUN, a plurality of devices relay data using a bucket relay system, and support multi-hop communication connecting remote locations. Therefore, the alarm device 10 and the plurality of alarm devices 11 can transmit data by a multi-hop method.
　以下の説明では、ＬＴＥモジュール１１２を搭載し、センタサーバ５０との無線通信が可能な警報装置１０を「マスタ装置１０」とも称し、ＬＴＥモジュール１１２を搭載していない警報装置１１を「スレーブ装置１１」とも称する。 In the following description, the alarm device 10 equipped with the LTE module 112 and capable of wireless communication with the center server 50 is also referred to as “master device 10”, and the alarm device 11 not equipped with the LTE module 112 is referred to as “slave device 11”. Is also referred to.
　図６は、実施の形態２に従うマルチホップ通信方式を説明するための図である。図６を参照して、マスタ装置１０Ａ，１０Ｂ，１０Ｃは、それぞれグループＡ，Ｂ，Ｃのマスタ装置である。通信範囲４０１，４０２，４０３は、それぞれマスタ装置１０Ａ，１０Ｂ，１０ＣがＷｉ－ＳＵＮを用いて通信する場合の通信範囲を示している。 FIG. 6 is a diagram for explaining the multi-hop communication method according to the second embodiment. Referring to FIG. 6, master devices 10A, 10B, and 10C are master devices of groups A, B, and C, respectively. Communication ranges 401, 402, and 403 indicate communication ranges when the master apparatuses 10A, 10B, and 10C communicate using Wi-SUN, respectively.
　スレーブ装置１１Ａ，１１Ｂ，１１Ｃは、通信範囲４０１に在圏しているため、グループＡに属している。スレーブ装置１１Ｃ，１１Ｄ，１１Ｅは、通信範囲４０２に在圏しているため、グループＢに属している。このことから、スレーブ装置１１Ｃは、グループＡおよびＢの両方に属している。スレーブ装置１１Ｇ，１１Ｆは、通信範囲４０３に在圏しているため、グループＣに属している。 The slave devices 11A, 11B, and 11C belong to the group A because they are located in the communication range 401. The slave devices 11C, 11D, and 11E belong to the group B because they are located in the communication range 402. Therefore, the slave device 11C belongs to both groups A and B. The slave devices 11G and 11F belong to the group C because they are located in the communication range 403.
　例えば、ネットワークに新規に参入するスレーブ装置１１は、マスタ装置１０との間で通信ルートを確立するために、マスタ装置１０、または、ネットワークに既に参入している他のスレーブ装置１１から、通信ルート、通信品質などの情報を含むルーティング情報を取得する必要がある。そこで、新規参入するスレーブ装置１１は、周囲に存在するマスタ装置１０や他のスレーブ装置１１を探索するためのビーコン要求信号をブロードキャスト送信する。 For example, in order to establish a communication route with the master device 10, the slave device 11 that newly enters the network receives a communication route from the master device 10 or another slave device 11 that has already entered the network. It is necessary to acquire routing information including information such as communication quality. Therefore, the newly entered slave device 11 broadcasts a beacon request signal for searching for the master device 10 and other slave devices 11 present in the vicinity.
　マスタ装置１０または他のスレーブ装置１１がビーコン要求信号を受信できれば、ビーコン要求信号を受信したマスタ装置１０または他のスレーブ装置１１は、ビーコン要求信号に対するビーコン応答信号をブロードキャスト送信する。新規参入するスレーブ装置１１は、ビーコン応答信号を受信すると、このビーコン応答信号の送信元との間で、ルーティング情報の送受信を行ない、通信ルートを構築する。 If the master device 10 or another slave device 11 can receive the beacon request signal, the master device 10 or the other slave device 11 that has received the beacon request signal broadcasts a beacon response signal for the beacon request signal. Upon receiving a beacon response signal, the newly joining slave device 11 transmits / receives routing information to / from the transmission source of the beacon response signal to construct a communication route.
　典型的には、マスタ装置１０は、同グループに属している各スレーブ装置１１から各種情報を受信して、当該各種情報をセンタサーバ５０に送信する。ここで、各スレーブ装置１１は、対応するガスメータから指定検針日における検針情報を受信し、当該受信した検針情報を当該スレーブ装置の内部メモリに記憶している。なお、各スレーブ装置は、上述した遮断関連情報および撮像情報等を内部メモリに記憶している。 Typically, the master device 10 receives various information from each slave device 11 belonging to the same group, and transmits the various information to the center server 50. Here, each slave device 11 receives the meter reading information on the designated meter reading date from the corresponding gas meter, and stores the received meter reading information in the internal memory of the slave device. Each slave device stores the above-described blocking-related information, imaging information, and the like in an internal memory.
　例えば、マスタ装置１０Ａは、スレーブ装置１１Ａ，１１Ｂ，１１Ｃの各々が内部メモリに記憶している検針情報や遮断情報を当該スレーブ装置１１から受信する。マスタ装置１０Ａは、スレーブ装置１１Ａ，１１Ｂ，１１Ｃの各々の検針情報および遮断情報をセンタサーバ５０に送信する。 For example, the master device 10A receives from the slave device 11 the meter reading information and the cutoff information stored in the internal memory of each of the slave devices 11A, 11B, and 11C. The master device 10A transmits the meter reading information and the cutoff information of each of the slave devices 11A, 11B, and 11C to the center server 50.
　なお、スレーブ装置１１ＣはグループＢにも属しているため、スレーブ装置１１Ｃの内部メモリに記憶された情報は、マスタ装置１０Ｂを介してセンタサーバ５０に送信されてもよい。 Note that since the slave device 11C also belongs to the group B, the information stored in the internal memory of the slave device 11C may be transmitted to the center server 50 via the master device 10B.
　ここで、あるマスタ装置１０が故障する等の要因により、当該マスタ装置１０がセンタサーバ５０および他のスレーブ装置１１と通信不能な状態になったケースを想定する。 Here, a case is assumed in which a master device 10 cannot communicate with the center server 50 and other slave devices 11 due to a failure of a certain master device 10 or the like.
　図７は、図６においてマスタ装置１０が故障した場合の局面を示す図である。図７を参照して、マスタ装置１０Ｂが故障する等の要因により、マスタ装置１０Ｂがセンタサーバ５０および他のスレーブ装置１１と通信不能な状態となっている。この場合、グループＢに属しているスレーブ装置１１Ｄおよび１１Ｅは、マスタ装置１０Ｂを介してセンタサーバ５０に情報を送信することができない。 FIG. 7 is a diagram showing a situation when the master device 10 in FIG. 6 fails. Referring to FIG. 7, master device 10B cannot communicate with center server 50 and other slave devices 11 due to factors such as failure of master device 10B. In this case, the slave devices 11D and 11E belonging to the group B cannot transmit information to the center server 50 via the master device 10B.
　そのため、スレーブ装置１１Ｅは、例えば、ビーコン要求信号を出して周囲に存在する他の装置を探索し、応答してきた（探索によって発見された）スレーブ装置１１Ｄとの通信を確立する。同様に、スレーブ装置１１Ｄはスレーブ装置１１Ｃとの通信を確立する。スレーブ装置１１Ｃは、スレーブ装置１１Ｂを介してマスタ装置１０Ａと通信可能である。すなわち、スレーブ装置１１Ｅは、スレーブ装置１１Ｄ，１１Ｃ，１１Ｂを介してマスタ装置１０Ａと通信可能になる。 Therefore, for example, the slave device 11E issues a beacon request signal to search for other devices existing in the vicinity, and establishes communication with the slave device 11D that has responded (discovered by the search). Similarly, the slave device 11D establishes communication with the slave device 11C. The slave device 11C can communicate with the master device 10A via the slave device 11B. That is, the slave device 11E can communicate with the master device 10A via the slave devices 11D, 11C, and 11B.
　したがって、スレーブ装置１１Ｅは、内部メモリに記憶している検針情報（あるいは、遮断情報等）をマスタ装置１０Ａに送信する。マスタ装置１０Ａは、スレーブ装置１１Ｅから受信した検針情報（あるいは、遮断情報）をセンタサーバ５０に送信する。 Therefore, the slave device 11E transmits the meter reading information (or the interruption information etc.) stored in the internal memory to the master device 10A. The master device 10A transmits the meter reading information (or blocking information) received from the slave device 11E to the center server 50.
　このように、スレーブ装置１１は、探索によって発見された装置Ｋ１に内部メモリに記憶された各種情報Ｐを送信する。そして、探索された装置Ｋ１がマスタ装置１０である場合には、装置Ｋ１は、当該スレーブ装置１１の内部メモリに記憶された各種情報Ｐをセンタサーバ５０に送信する。一方、探索された装置Ｋ１がスレーブ装置１１である場合には、装置Ｋ１は、さらに自身によって探索された他の装置Ｋ２に各種情報Ｐを送信する。 In this way, the slave device 11 transmits various information P stored in the internal memory to the device K1 discovered by the search. When the searched device K 1 is the master device 10, the device K 1 transmits various information P stored in the internal memory of the slave device 11 to the center server 50. On the other hand, when the searched device K1 is the slave device 11, the device K1 further transmits various information P to another device K2 searched by itself.
　なお、図６および図７中の通信ルートは一例であって、他の通信ルートが採用される構成であってもよい。例えば、スレーブ装置１１Ｅが探索によってスレーブ装置１１Ｃを発見した場合には、スレーブ装置１１Ｅは、スレーブ装置１１Ｄを介さずにスレーブ装置１１Ｃとの通信を確立する。さらに、スレーブ装置１１Ｃは、探索によってマスタ装置１０Ａを発見した場合には、スレーブ装置１１Ｂを介さずにマスタ装置１０Ａとの通信を確立する。この場合、スレーブ装置１１Ｅは、スレーブ装置１１Ｃを介してマスタ装置１０Ａと通信可能になる。 Note that the communication routes in FIGS. 6 and 7 are merely examples, and other communication routes may be adopted. For example, when the slave device 11E finds the slave device 11C by searching, the slave device 11E establishes communication with the slave device 11C without going through the slave device 11D. Furthermore, when the slave device 11C finds the master device 10A through the search, the slave device 11C establishes communication with the master device 10A without going through the slave device 11B. In this case, the slave device 11E can communicate with the master device 10A via the slave device 11C.
