データ中継システム、中継リーダ装置、中継タグ装置、中継装置およびデータ中継方法Data relay system, relay reader device, relay tag device, relay device, and data relay method
　本発明は、センサーネットワークの構築に適したデータ中継システムに関するものである。 The present invention relates to a data relay system suitable for building a sensor network.
　従来、建築物や構造物の点検や監視を行うために、センサーノードと基地局によりセンサーネットワークを構築する手法が提案されている（例えば特許文献１参照）。従来のセンサーネットワークでは、センサーノードと基地局とが互いに無線通信可能な位置に設置されており、センサーネットワークを利用して取得した情報に基づいて、点検や監視が行われる。 Conventionally, a method for constructing a sensor network by sensor nodes and base stations has been proposed in order to inspect and monitor buildings and structures (see, for example, Patent Document 1). In a conventional sensor network, a sensor node and a base station are installed at positions where they can communicate with each other wirelessly, and inspection and monitoring are performed based on information acquired using the sensor network.
　しかしながら、従来のセンサーネットワークでは、センサーノードと基地局が互いに無線通信できる位置にあることが前提であり、基地局と無線通信できない位置にセンサーノードを設置することはできなかった。 However, the conventional sensor network is based on the premise that the sensor node and the base station can communicate with each other wirelessly, and the sensor node cannot be installed at a position where the wireless communication with the base station cannot be performed.
　例えば、高速道路や橋梁などの構造物を点検する場合、車両に基地局装置（タグリーダ装置）を搭載し、車両を走行させながら、構造物（高速道路や橋梁など）に設置されたセンサーノード（データロガー装置）から情報を収集する方法が利用される。ところが、そのような場合、データロガー装置を、高速道路の支柱や橋脚など、車両に搭載されたタグリーダ装置からの電波の届かない箇所に設置しなければならない場合もあり、従来のセンサーネットワークでは、対応することができなかった。 For example, when inspecting a structure such as a highway or a bridge, a sensor node (such as a highway or a bridge) installed on the structure (a highway or a bridge) while the vehicle is mounted with a base station device (tag reader device) mounted on the vehicle. A method of collecting information from a data logger device) is used. However, in such a case, the data logger device may need to be installed in a place where radio waves from the tag reader device mounted on the vehicle do not reach, such as a highway post or a pier, I could not respond.
　また、タグリーダ装置を車両に搭載して、車両を高速（例えば、時速８０ｋｍ）で走行させながら情報を収集しようとする場合、同時に多数のセンサーノードから情報を取得するのが困難であった。 Further, when a tag reader device is mounted on a vehicle and information is collected while the vehicle is traveling at a high speed (for example, 80 km / h), it is difficult to simultaneously acquire information from a large number of sensor nodes.

　以下に本発明の詳細な説明を述べる。ただし、以下の詳細な説明と添付の図面は発明を限定するものではない。 The detailed description of the present invention will be described below. However, the following detailed description and the accompanying drawings do not limit the invention.
　本発明のデータ中継システムは、センサー装置からのセンサー入力を記録するデータロガー装置と、データロガー装置と通信可能な中継リーダ装置と、中継リーダ装置と通信可能な中継タグ装置と、中継タグ装置と通信可能なタグリーダ装置とを備えたデータ中継システムにおいて、データロガー装置は、センサー入力に基づいて、センサー装置の監視対象の異常の有無を示すアラーム情報を生成するアラーム情報生成部と、アラーム情報を中継リーダ装置へ送信するアラーム情報送信部と、を備え、中継リーダ装置は、複数のデータロガー装置からアラーム情報を収集するアラーム情報収集部と、複数のアラーム情報を統合して統合アラーム情報を生成する統合アラーム情報生成部と、統合アラーム情報を中継タグ装置へ送信する統合アラーム情報送信部と、を備え、中継タグ装置は、中継リーダ装置から統合アラーム情報を受信する統合アラーム情報受信部と、受信した統合アラーム情報を記憶する統合アラーム情報記憶部と、タグリーダ装置からのデータ要求信号に対する応答として、記憶した統合アラーム情報をタグリーダ装置へ送信する応答送信部と、を備え、アラーム情報は、データロガー装置からタグリーダ装置へ送信可能なフォーマットで生成され、統合アラーム情報は、アラーム情報と同じフォーマットで生成される構成を有している。 The data relay system of the present invention includes a data logger device that records sensor input from a sensor device, a relay reader device that can communicate with the data logger device, a relay tag device that can communicate with the relay reader device, and a relay tag device. In a data relay system having a communicable tag reader device, a data logger device generates an alarm information indicating whether there is an abnormality of a monitoring target of the sensor device based on a sensor input, and an alarm information An alarm information transmission unit that transmits to the relay reader device, and the relay reader device integrates the alarm information collection unit that collects alarm information from a plurality of data logger devices and generates the integrated alarm information Integrated alarm information generation unit that transmits the integrated alarm information to the relay tag device. A relay tag device that receives integrated alarm information from the relay reader device, an integrated alarm information storage unit that stores the received integrated alarm information, and a tag reader device. A response transmission unit that transmits the stored integrated alarm information to the tag reader device as a response to the data request signal, the alarm information is generated in a format that can be transmitted from the data logger device to the tag reader device, and the integrated alarm information is The alarm information is generated in the same format as the alarm information.
　この構成により、データロガー装置に記録された情報（センサー装置の監視対象の異常の有無を示す情報）が、中継リーダ装置と中継タグ装置を介して、データロガー装置からタグリーダ装置へ伝達される。そのため、データロガー装置がタグリーダ装置と直接通信できない箇所（タグリーダ装置からの電波が届かない箇所）に設置された場合でも、中継リーダ装置と中継タグ装置を介して、タグリーダ装置へ情報を伝達することができる。つまり、データロガー装置を、タグリーダ装置からの電波が届かない箇所にも設置することができる。 With this configuration, information recorded in the data logger device (information indicating whether there is an abnormality in the monitoring target of the sensor device) is transmitted from the data logger device to the tag reader device via the relay reader device and the relay tag device. Therefore, even when the data logger device is installed at a location where it cannot communicate directly with the tag reader device (a location where radio waves from the tag reader device do not reach), information is transmitted to the tag reader device via the relay reader device and the relay tag device. Can do. That is, the data logger device can be installed at a location where radio waves from the tag reader device do not reach.
　また、この場合、複数のデータロガー装置から収集されたアラーム情報が、一つの統合アラーム情報に統合されて、タグリーダ装置へ送信される。この統合アラーム情報は、アラーム情報と同じフォーマットで生成される。例えば、アラーム情報のフォーマットが、「センサー種別、センサー状態、センサー日時」で構成される場合、統合アラーム情報のフォーマットも、「センサー種別、センサー状態、センサー日時」で構成される。（ただし、アラーム情報の内容は、例えば、「センサー種別」が「各センサーの種別を示す情報」、「センサー状態」が「各センサーの正常／異常を示す情報」、「センサー日時」が「正常時は現在日時／異常時は異常発生日時」などであるのに対して、統合アラーム情報の内容は、例えば、「センサー種別」が「統合データを示す情報」、「センサー状態」が「各センサーの異常の論理和」、「センサー日時」が「現在日時／異常発生日時のうち最も古い日時」などである。）したがって、統合アラーム情報は、アラーム情報がデータロガー装置からタグリーダ装置へ送信されるのと同じ様に、中継タグ装置からタグリーダ装置へ送信することができる。例えば、アラーム情報が、高速（例えば、時速８０ｋｍ）で移動中のタグリーダ装置へデータロガー装置から送信できる場合には、統合アラーム情報も、同様に、高速で移動中のタグリーダ装置へ中継タグ装置から送信できる。 In this case, alarm information collected from a plurality of data logger devices is integrated into one integrated alarm information and transmitted to the tag reader device. This integrated alarm information is generated in the same format as the alarm information. For example, when the alarm information format is configured by “sensor type, sensor status, sensor date and time”, the integrated alarm information format is also configured by “sensor type, sensor status, sensor date and time”. (However, the content of the alarm information is, for example, “sensor type” is “information indicating the type of each sensor”, “sensor status” is “information indicating normality / abnormality of each sensor”, and “sensor date and time” is “normal”. The time is the current date / time and the time and date of occurrence of the abnormality is the time and the like, while the content of the integrated alarm information is, for example, “sensor type” is “information indicating integrated data”, and “sensor status” is “each sensor” And the sensor date / time is “the current date / time and the date / time when the error occurred”, etc.) Therefore, in the integrated alarm information, the alarm information is transmitted from the data logger device to the tag reader device. In the same manner as above, the relay tag device can transmit to the tag reader device. For example, if the alarm information can be transmitted from the data logger device to the tag reader device moving at a high speed (for example, 80 km / h), the integrated alarm information is similarly transferred from the relay tag device to the tag reader device moving at a high speed. Can be sent.
　本発明によれば、タグリーダ装置からの電波が届かない箇所にもデータロガー装置を設置することができ、複数のデータロガー装置に記録された情報（センサー装置の監視対象の異常の有無を示す情報）を、高速で移動するタグリーダ装置からでも容易に収集することができる。 According to the present invention, a data logger device can be installed at a location where radio waves from the tag reader device do not reach, and information recorded in a plurality of data logger devices (information indicating whether there is an abnormality in the monitoring target of the sensor device) ) Can be easily collected even from a tag reader that moves at high speed.
　また、本発明のデータ中継システムでは、中継リーダ装置は、統合アラーム情報を中継タグ装置へ送信するときに、統合アラーム情報記憶に記憶された統合アラーム情報の更新を要求する更新要求信号を送信する更新要求部を備え、中継タグ装置は、中継リーダ装置からの更新要求信号の受信に応じて、統合アラーム情報記憶に記憶された統合アラーム情報を更新する統合アラーム情報更新部を備えた構成を有してよい。 In the data relay system of the present invention, the relay reader device transmits an update request signal for requesting the update of the integrated alarm information stored in the integrated alarm information storage when transmitting the integrated alarm information to the relay tag device. The relay tag device includes an update request unit, and has a configuration including an integrated alarm information update unit that updates the integrated alarm information stored in the integrated alarm information storage in response to reception of an update request signal from the relay reader device. You can do it.
　この構成により、中継リーダ装置から中継タグ装置に統合アラーム情報が送信されるときに、更新要求信号が一緒に送信される。中継タグ装置では、中継リーダ装置から更新要求信号を受信すると、統合アラーム情報記憶に記憶された統合アラーム情報が更新される。中継タグ装置は、タグリーダ装置からデータ要求信号を受信すると、更新された統合アラーム情報をタグリーダ装置へ送信する。このようにして、最新の情報（更新された統合
アラーム情報）を容易に取得することが可能になる。 With this configuration, when the integrated alarm information is transmitted from the relay reader device to the relay tag device, an update request signal is transmitted together. In the relay tag device, when the update request signal is received from the relay reader device, the integrated alarm information stored in the integrated alarm information storage is updated. When the relay tag device receives the data request signal from the tag reader device, the relay tag device transmits the updated integrated alarm information to the tag reader device. In this way, the latest information (updated integrated alarm information) can be easily obtained.
　また、本発明のデータ中継システムでは、アラーム情報収集部は、定期的にデータロガー装置からアラーム情報を収集する構成を有してよい。 In the data relay system of the present invention, the alarm information collection unit may have a configuration for collecting alarm information from the data logger device periodically.
　この構成により、中継リーダ装置は、定期的に（例えば、１日１回）データロガー装置からアラーム情報を収集する。そして、定期的に収集されたアラーム情報は、中継リーダ装置で統合アラーム情報に統合され、中継タグ装置からタグリーダ装置へ送信される。このようにして、定期的に収集した情報を容易に取得することが可能になる。 With this configuration, the relay reader device collects alarm information from the data logger device periodically (for example, once a day).

That is, the data logger device 2 may be installed at a location where radio waves reach from the tag reader device 5.
　中継リーダ装置３は、データロガー装置２からの電波が届く箇所に設置されており、データロガー装置２と通信可能である。また、中継リーダ装置３は、中継タグ装置４からの電波が届く箇所に設置されており、中継タグ装置４とも通信可能である。 The relay reader device 3 is installed at a location where radio waves from the data logger device 2 reach and can communicate with the data logger device 2. The relay reader device 3 is installed at a location where radio waves from the relay tag device 4 reach, and can communicate with the relay tag device 4.

It is also possible to communicate with the tag reader device 5 mounted on a vehicle traveling on the road.
　ここで、図２～図４を参照しながら、データロガー装置２、中継リーダ装置３、中継タグ装置４の各構成について詳しく説明する。 Here, each configuration of the data logger device 2, the relay reader device 3, and the relay tag device 4 will be described in detail with reference to FIGS.
　図２は、データロガー装置２の構成を示すブロック図である。図２に示すように、データロガー装置２は、センサー装置６からのセンサー入力（センサー値）を受け付けるセンサーインターフェース（センサーＩ／Ｆ）７と、ＣＰＵなどで構成される制御部８を備えている。また、データロガー装置２は、アクティブＲＦＩＤモジュール（Ａ－ＲＦＩＤモジュール）やＷｉ－Ｆｉモジュールなどで構成される通信部９と、メモリなどで構成される記憶部１０を備えている。 FIG. 2 is a block diagram showing the configuration of the data logger device 2. As shown in FIG. 2, the data logger device 2 includes a sensor interface (sensor I / F) 7 that receives a sensor input (sensor value) from the sensor device 6, and a control unit 8 including a CPU and the like. .

　制御部８は、センサー入力（センサー値）に基づいてアラーム情報を生成するアラーム情報生成部１１と、アラーム情報を中継リーダ装置３へ送信する制御を行う送信制御部１２を備えている。アラーム情報生成部１１は、センサー値が所定の閾値以上である場合には、そのセンサー装置６の監視対象（構造物の一部）に異常があることを示すアラーム情報を生成する。一方、アラーム情報生成部１１は、センサー値が所定の閾値未満である場合には、そのセンサー装置６の監視対象（構造物の一部）に正常があることを示すアラーム情報を生成する。送信制御部１２は、後述するように、中継リーダ装置３からビーコンを受信すると、その応答としてアラーム情報を中継リーダ装置３へ送信（返信）するように通信部９を制御する。入力されたセンサー値（測定データ）と、生成したアラーム情報は、記憶部１０に記憶される。 The control unit 8 includes an alarm information generation unit 11 that generates alarm information based on a sensor input (sensor value), and a transmission control unit 12 that performs control to transmit the alarm information to the relay reader device 3. When the sensor value is equal to or greater than a predetermined threshold, the alarm information generation unit 11 generates alarm information indicating that the monitoring target (part of the structure) of the sensor device 6 is abnormal. On the other hand, when the sensor value is less than the predetermined threshold, the alarm information generation unit 11 generates alarm information indicating that the monitoring target (part of the structure) of the sensor device 6 is normal. As will be described later, when receiving a beacon from the relay reader device 3, the transmission control unit 12 controls the communication unit 9 to transmit (reply) alarm information to the relay reader device 3 as a response. The input sensor value (measurement data) and the generated alarm information are stored in the storage unit 10.
　ここで、アラーム情報について説明しておく。アラーム情報のフォーマットは、「センサー種別、センサー状態、センサー日時」で構成される。「センサー種別」は、各センサーの種別を示す１バイトの情報（例えば、０ｘ００：センサーなし、０ｘ０１：接点センサー、０ｘ０２：４ゲージ歪みセンサー、など）である。「センサー状態」は、各センサーの正常／異常を示す１バイトの情報（例えば、０ｘ００：正常、０ｘ０１：異常、など）である。「センサー日時」は、センサーの正常時は現在日時、センサーの異常時は異常発生日時を示す４バイトの情報（例えば、ＵＮＩＸ時刻）である。 Here, the alarm information will be explained. The alarm information format is composed of “sensor type, sensor state, sensor date and time”. The “sensor type” is 1-byte information (for example, 0x00: no sensor, 0x01: contact sensor, 0x02: 4-gauge strain sensor, etc.) indicating the type of each sensor. “Sensor state” is 1-byte information indicating normality / abnormality of each sensor (for example, 0x00: normal, 0x01: abnormal, etc.). “Sensor date” is 4-byte information (for example, UNIX time) indicating the current date and time when the sensor is normal, and the date and time when the sensor is abnormal when the sensor is abnormal.
　図３は、中継リーダ装置３の構成を示すブロック図である。図３に示すように、中継リーダ装置３は、ＣＰＵなどで構成される制御部１３と、アクティブＲＦＩＤモジュール（Ａ－ＲＦＩＤモジュール）やＷｉ－Ｆｉモジュールなどで構成される通信部１４を備えている。また、中継リーダ装置３は、メモリなどで構成される記憶部１５とリスト保持部１６を備えている。 FIG. 3 is a block diagram showing a configuration of the relay reader device 3. As shown in FIG. 3, the relay reader device 3 includes a control unit 13 configured with a CPU and the like, and a communication unit 14 configured with an active RFID module (A-RFID module), a Wi-Fi module, and the like. . In addition, the relay reader device 3 includes a storage unit 15 and a list holding unit 16 configured by a memory or the like.
　制御部１３は、複数のデータロガー装置２からアラーム情報を収集する制御を行う収集制御部１７と、収集した複数のアラーム情報を統合して統合アラーム情報を生成する統合アラーム情報生成部１８を備えている。また、この制御部１３は、統合アラーム情報を中継タグ装置４へ送信する制御を行う送信制御部１９と、中継タグ装置４に記憶された統合アラーム情報の更新を要求する更新要求部２０を備えている。 The control unit 13 includes a collection control unit 17 that performs control to collect alarm information from the plurality of data logger devices 2, and an integrated alarm information generation unit 18 that integrates the collected plurality of alarm information to generate integrated alarm information. ing. The control unit 13 includes a transmission control unit 19 that performs control to transmit the integrated alarm information to the relay tag device 4 and an update request unit 20 that requests an update of the integrated alarm information stored in the relay tag device 4. ing.
　収集制御部１７は、定期的に（例えば、１日１回）起動して、複数のデータロガー装置２に対して、アラーム情報の送信を要求するビーコン（データ要求信号）を送信するように通信部１４を制御する。データロガー装置２は、中継リーダ装置３からのビーコンを受信すると、その応答としてアラーム情報を中継リーダ装置３へ送信（返信）する。リスト保持部１６には、収集対象となるデータロガー装置2を示すロガーリストが記憶されている。収集制御部１７はロガーリストに基づいて、収集が完了したかどうかを判定する。収集制御部１７は一定時間（例えば５分間）起動してロガーリストに記憶されている全てのデータロガー装置２からアラーム情報の収集が完了したか判定を行い、正常に収集できた時は統合アラーム生成部１８に正常な統合アラーム情報であることを示す情報（例えば、０xＥ０）を設定し、収集に異常がある時は統合アラーム生成部１８に異常な統合アラーム情報であることを示す情報（例えば、０xＥ１）を設定する。 The collection control unit 17 is periodically activated (for example, once a day) and communicates so as to transmit beacons (data request signals) for requesting transmission of alarm information to the plurality of data logger devices 2. The unit 14 is controlled. When the data logger device 2 receives a beacon from the relay reader device 3, it transmits (replies) alarm information to the relay reader device 3 as a response. The list holding unit 16 stores a logger list indicating the data logger device 2 to be collected. The collection control unit 17 determines whether collection is completed based on the logger list. The collection control unit 17 is activated for a certain time (for example, 5 minutes) and determines whether or not the collection of alarm information has been completed from all the data logger devices 2 stored in the logger list. Information indicating normal integrated alarm information (for example, 0xE0) is set in the generation unit 18, and when there is an abnormality in collection, information indicating that the integrated alarm generation unit 18 is abnormal integrated alarm information (for example, , 0xE1).
　統合アラーム情報生成部１８は、複数のアラーム情報を統合することにより統合アラーム情報を生成する。ここで、統合アラーム情報について説明しておく。統合アラーム情報のフォーマットは、アラーム情報のフォーマットと同じであり、「センサー種別、センサー状態、センサー日時」で構成される。ただし、「センサー種別」は、統合アラーム情報であることを示す１バイトの情報（例えば、０ｘＥ０、０ｘＥ１、など）である。また、「センサー状態」は、各センサーの異常の論理和を示す１バイトの情報（例えば、０ｘ００：すべてのセンサーが正常、０ｘ０１：どこかのセンサーが異常、など）である。また、「センサー日時」は、各センサー日時（現在日時／異常発生日時）のうち最も古い日時を示す４バイトの情報（例えば、ＵＮＩＸ時刻）である。収集したアラーム情報と、生成された統合アラーム情報は、記憶部１５に記憶される。 The integrated alarm information generation unit 18 generates integrated alarm information by integrating a plurality of alarm information. Here, the integrated alarm information will be described. The format of the integrated alarm information is the same as the format of the alarm information, and includes “sensor type, sensor state, sensor date and time”. However, “sensor type” is 1-byte information (for example, 0xE0, 0xE1, etc.) indicating integrated alarm information. The “sensor state” is 1-byte information (for example, 0x00: all sensors are normal, 0x01: some sensor is abnormal, etc.) indicating the logical sum of abnormality of each sensor. The “sensor date / time” is 4-byte information (for example, UNIX time) indicating the oldest date / time of each sensor date / time (current date / abnormality date / time). The collected alarm information and the generated integrated alarm information are stored in the storage unit 15.
　送信制御部１９は、統合アラーム情報を中継タグ装置４へ送信するように通信部１４を制御する。更新要求部２０は、統合アラーム情報を中継タグ装置４へ送信するときに、中継タグ装置４に記憶された統合アラーム情報の更新を要求する中継ビーコン（更新要求信号）を、中継タグ装置４へ送信するように通信部１４を制御する。リスト保持部１６には、中継ビーコンの送信対象となる中継タグ装置４を示す中継タグリストが記憶されている。更新要求部２０は、中継タグリストに基づいて、中継ビーコンを送信する中継タグ装置４を決定する。つまり、更新要求部２０は、中継タグリストで指定された中継タグ装置４に対して、中継ビーコンを送信する制御を行う。なお、統合アラーム情報は、中継ビーコンに含めて送信することができる。 The transmission control unit 19 controls the communication unit 14 to transmit the integrated alarm information to the relay tag device 4. When the update request unit 20 transmits the integrated alarm information to the relay tag device 4, the update request unit 20 sends a relay beacon (update request signal) requesting the update of the integrated alarm information stored in the relay tag device 4 to the relay tag device 4. The communication unit 14 is controlled to transmit. The list holding unit 16 stores a relay tag list indicating the relay tag device 4 that is a transmission target of the relay beacon. The update request unit 20 determines the relay tag device 4 that transmits the relay beacon based on the relay tag list. That is, the update request unit 20 performs control to transmit a relay beacon to the relay tag device 4 specified in the relay tag list. The integrated alarm information can be transmitted by being included in the relay beacon.
　図４は、中継タグ装置４の構成を示すブロック図である。図４に示すように、中継タグ装置４は、ＣＰＵなどで構成される制御部２１と、アクティブＲＦＩＤモジュール（Ａ－ＲＦＩＤモジュール）やＷｉ－Ｆｉモジュールなどで構成される通信部２２を備えている。また、中継リーダ装置３は、メモリなどで構成される記憶部２３とリスト保持部２４を備えている。 FIG. 4 is a block diagram showing a configuration of the relay tag device 4. As shown in FIG. 4, the relay tag device 4 includes a control unit 21 configured with a CPU and the like, and a communication unit 22 configured with an active RFID module (A-RFID module), a Wi-Fi module, and the like. . In addition, the relay reader device 3 includes a storage unit 23 and a list holding unit 24 configured by a memory or the like.
　制御部２１は、中継リーダ装置３から送信される中継ビーコンや統合アラーム情報（中継ビーコンに含まれる統合アラーム情報）を受信する制御を行う受信制御部２５を備えている。受信した統合アラーム情報は、記憶部２３に記憶される。リスト保持部２４には、どの中継リーダ装置３から統合アラーム情報を受信すべきかを示す中継リーダリストが記憶されている。 The control unit 21 includes a reception control unit 25 that performs control to receive a relay beacon and integrated alarm information (integrated alarm information included in the relay beacon) transmitted from the relay reader device 3. The received integrated alarm information is stored in the storage unit 23. The list holding unit 24 stores a relay reader list indicating which relay reader device 3 should receive the integrated alarm information.
　また、制御部２１は、タグリーダ装置５からのビーコン（データ要求信号）に対する応答として、統合アラーム情報をタグリーダ装置５へ送信（返信）する制御を行う応答制御部２６を備えている。さらに、制御部２１は、中継リーダ装置３からの中継ビーコン（更新要求信号）を受信すると、記憶部２３に記憶されている統合アラーム情報を、受信した統合アラーム情報（最新の統合アラーム情報）に更新する更新処理部２７を備えている。 Further, the control unit 21 includes a response control unit 26 that performs control to transmit (reply) the integrated alarm information to the tag reader device 5 as a response to the beacon (data request signal) from the tag reader device 5. Further, when receiving the relay beacon (update request signal) from the relay reader device 3, the control unit 21 converts the integrated alarm information stored in the storage unit 23 into the received integrated alarm information (latest integrated alarm information). An update processing unit 27 for updating is provided.
　以上のように構成されたデータ中継システム１について、図５のシーケンス図を参照してその動作を説明する。 The operation of the data relay system 1 configured as described above will be described with reference to the sequence diagram of FIG.
　本実施の形態のデータ中継システム１では、センサー装置６からのセンサー入力（センサー値）がデータロガー装置２に記録される。中継リーダ装置３は、定期的に起動して、データロガー装置２へビーコン（データ要求信号）を送信する（Ｓ１）。データロガー装置２は、ビーコンへの応答として、アラーム情報を中継リーダ装置３へ送信する（Ｓ２）。中継リーダ装置３は、複数のデータロガー装置２からアラーム情報を受信すると、それらを統合して統合アラーム情報を生成する（Ｓ３）。 In the data relay system 1 of the present embodiment, the sensor input (sensor value) from the sensor device 6 is recorded in the data logger device 2. The relay reader device 3 is periodically activated and transmits a beacon (data request signal) to the data logger device 2 (S1). The data logger device 2 transmits alarm information to the relay reader device 3 as a response to the beacon (S2). When receiving the alarm information from the plurality of data logger devices 2, the relay reader device 3 integrates them to generate integrated alarm information (S3).
　つぎに、中継リーダ装置３は、中継ビーコンを中継タグ装置４へ送信する（Ｓ４）。この中継ビーコンには統合アラーム情報が含まれている。中継タグ装置４は、中継ビーコンを受信すると、統合アラーム情報の更新を行う（Ｓ５）。具体的には、記憶部２３に記憶されている統合アラーム情報を、受信した統合アラーム情報に更新する。 Next, the relay reader device 3 transmits a relay beacon to the relay tag device 4 (S4). This relay beacon includes integrated alarm information. When the relay tag device 4 receives the relay beacon, the relay tag device 4 updates the integrated alarm information (S5). Specifically, the integrated alarm information stored in the storage unit 23 is updated to the received integrated alarm information.
　その後、タグリーダ装置５を搭載した車両が中継タグ装置４の付近を走行したときに、タグリーダ装置５から中継タグ装置４へビーコン（データ要求信号）が送信されると（Ｓ６）、中継タグ装置４は、その応答として、統合アラーム情報をタグリーダ装置５へ送信する（Ｓ７）。 Thereafter, when a vehicle equipped with the tag reader device 5 travels in the vicinity of the relay tag device 4, a beacon (data request signal) is transmitted from the tag reader device 5 to the relay tag device 4 (S6). In response to this, the integrated alarm information is transmitted to the tag reader device 5 (S7).
　このような第１の実施の形態のデータ中継システム１によれば、タグリーダ装置５から電波の届かない箇所にもデータロガー装置２を設置することができ、複数のデータロガー装置２に記録された情報を、高速で移動するタグリーダ装置５からでも容易に収集することができる。 According to the data relay system 1 of the first embodiment as described above, the data logger device 2 can be installed in a place where the radio wave does not reach from the tag reader device 5, and the data logger device 2 is recorded on the plurality of data logger devices 2. Information can be easily collected even from the tag reader device 5 that moves at high speed.
　すなわち、本実施の形態では、データロガー装置２に記録された情報（センサー装置６の監視対象の異常の有無を示す情報）が、中継リーダ装置３と中継タグ装置４を介して、データロガー装置２からタグリーダ装置５へ伝達される。そのため、データロガー装置２がタグリーダ装置５と直接通信できない箇所（タグリーダ装置５からの電波が届かない箇所）に設置された場合でも、中継リーダ装置３と中継タグ装置４を介して、タグリーダ装置５へ情報を伝達することができる。つまり、データロガー装置２を、タグリーダ装置５からの電波が届かない箇所にも設置することができる。 In other words, in the present embodiment, information recorded in the data logger device 2 (information indicating whether there is an abnormality to be monitored by the sensor device 6) is transmitted via the relay reader device 3 and the relay tag device 4 to the data logger device. 2 to the tag reader device 5. Therefore, even when the data logger device 2 is installed at a location where the data logger device 2 cannot communicate directly with the tag reader device 5 (a location where radio waves from the tag reader device 5 do not reach), the tag reader device 5 is connected via the relay reader device 3 and the relay tag device 4. Information can be transmitted to That is, the data logger device 2 can be installed at a location where radio waves from the tag reader device 5 do not reach.
　また、この場合、複数のデータロガー装置２から収集されたアラーム情報が、一つの統合アラーム情報に統合されて、タグリーダ装置５へ送信される。この統合アラーム情報は、アラーム情報と同じフォーマットで生成される。例えば、アラーム情報のフォーマットが、「センサー種別、センサー状態、センサー日時」で構成される場合、統合アラーム情報のフォーマットも、「センサー種別、センサー状態、センサー日時」で構成される。（ただし、アラーム情報の内容は、例えば、「センサー種別」が「各センサーの種別を示す情報」、「センサー状態」が「各センサーの正常／異常を示す情報」、「センサー日時」が「正常時は現在日時／異常時は異常発生日時」などであるのに対して、統合アラーム情報の内容は、例えば、「センサー種別」が「統合データを示す情報」、「センサー状態」が「各センサーの異常の論理和」、「センサー日時」が「現在日時／異常発生日時のうち最も古い日時」などである。）したがって、統合アラーム情報は、アラーム情報がデータロガー装置２からタグリーダ装置５へ送信されるのと同じ様に、中継タグ装置４からタグリーダ装置５へ送信することができる。例えば、アラーム情報が、高速（例えば、時速８０ｋｍ）で移動中のタグリーダ装置５へデータロガー装置２から送信できる場合には、統合アラーム情報も、同様に、高速で移動中のタグリーダ装置５へ中継タグ装置４から送信できる。 In this case, the alarm information collected from the plurality of data logger devices 2 is integrated into one integrated alarm information and transmitted to the tag reader device 5. This integrated alarm information is generated in the same format as the alarm information. For example, when the alarm information format is configured by “sensor type, sensor status, sensor date and time”, the integrated alarm information format is also configured by “sensor type, sensor status, sensor date and time”. (However, the content of the alarm information is, for example, “sensor type” is “information indicating the type of each sensor”, “sensor status” is “information indicating normality / abnormality of each sensor”, and “sensor date and time” is “normal”. The time is the current date / time and the time and date of occurrence of the abnormality is the time and the like, while the content of the integrated alarm information is, for example, “sensor type” is “information indicating integrated data”, and “sensor status” is “each sensor” And the sensor date / time is “the current date / time and the date / time when the error occurred is the oldest date / time”, etc.) Therefore, in the integrated alarm information, the alarm information is transmitted from the data logger device 2 to the tag reader device 5. In the same manner as described above, the relay tag device 4 can transmit to the tag reader device 5. For example, when the alarm information can be transmitted from the data logger device 2 to the tag reader device 5 moving at a high speed (for example, 80 km / h), the integrated alarm information is similarly relayed to the tag reader device 5 moving at a high speed. It can be transmitted from the tag device 4.
　このように、本実施の形態のデータ中継システム１によれば、タグリーダ装置５からの電波が届かない箇所にもデータロガー装置２を設置することができ、複数のデータロガー装置２に記録された情報（センサー装置６の監視対象の異常の有無を示す情報）を、高速で移動するタグリーダ装置５からでも容易に収集することができる。 As described above, according to the data relay system 1 of the present embodiment, the data logger device 2 can be installed at a location where the radio wave from the tag reader device 5 does not reach and is recorded in the plurality of data logger devices 2. Information (information indicating whether there is an abnormality in the monitoring target of the sensor device 6) can be easily collected even from the tag reader device 5 that moves at high speed.
　また、本実施の形態では、中継リーダ装置３から中継タグ装置４に統合アラーム情報が送信されるときに、更新要求信号が一緒に送信される。中継タグ装置４では、中継リーダ装置３から更新要求信号を受信すると、統合アラーム情報記憶に記憶された統合アラーム情報が更新される。中継タグ装置４は、タグリーダ装置５からデータ要求信号を受信すると、更新された統合アラーム情報をタグリーダ装置５へ送信する。このようにして、最新の情報（更新された統合アラーム情報）を容易に取得することが可能になる。 In the present embodiment, when the integrated alarm information is transmitted from the relay reader device 3 to the relay tag device 4, an update request signal is transmitted together. When the relay tag device 4 receives the update request signal from the relay reader device 3, the integrated alarm information stored in the integrated alarm information storage is updated. When the relay tag device 4 receives the data request signal from the tag reader device 5, it transmits the updated integrated alarm information to the tag reader device 5. In this way, the latest information (updated integrated alarm information) can be easily obtained.
　また、本実施の形態では、中継リーダ装置３は、定期的に（例えば、１日１回）データロガー装置２からアラーム情報を収集する。そして、定期的に収集されたアラーム情報は、中継リーダ装置３で統合アラーム情報に統合され、中継タグ装置４からタグリーダ装置５へ送信される。このようにして、定期的に収集した情報を容易に取得することが可能になる。 In the present embodiment, the relay reader device 3 collects alarm information from the data logger device 2 periodically (for example, once a day). The alarm information collected periodically is integrated into the integrated alarm information by the relay reader device 3 and transmitted from the relay tag device 4 to the tag reader device 5. In this way, it is possible to easily acquire information collected periodically.

In addition, the control unit 31 includes a response control unit 37 that performs control to transmit (reply) the integrated alarm information to the tag reader device 5 as a response to the beacon (data request signal) from the tag reader device 5. Furthermore, the control unit 31 includes an update processing unit 38 that updates the integrated alarm information stored in the storage unit 33 to the generated integrated alarm information (latest integrated alarm information) when the generation of the integrated alarm information is completed. ing. The collected alarm information and the generated integrated alarm information are stored in the storage unit 33.
　収集制御部３５は、第１の実施の形態と同様、定期的に（例えば、１日１回）起動して、複数のデータロガー装置２に対して、アラーム情報の送信を要求するビーコン（データ要求信号）を送信するように通信部３２を制御する。データロガー装置２は、中継装置からのビーコンを受信すると、その応答としてアラーム情報を中継装置へ送信（返信）する。リスト保持部３４には、収集対象となるデータロガー装置2を示すロガーリストが記憶されている。収集制御部３５はロガーリストに基づいて、収集が完了したかどうかを判定する。収集制御部３５は一定時間（例えば５分間）起動してロガーリストに記憶されている全てのデータロガー装置２からアラーム情報の収集が完了したか判定を行う。 As in the first embodiment, the collection control unit 35 is activated periodically (for example, once a day), and beacons (data that request transmission of alarm information to a plurality of data logger devices 2. The communication unit 32 is controlled to transmit a request signal. When receiving a beacon from the relay device, the data logger device 2 transmits (replies) alarm information to the relay device as a response. The list holding unit 34 stores a logger list indicating the data logger device 2 to be collected. The collection control unit 35 determines whether collection is completed based on the logger list.
