Description

データ通信システム、及び、データ通信方法Data communication system and data communication method
　本発明は、店舗に設置された機器のデータをネットワーク経由で収集するデータ通信システム、及び、データ通信方法に関するものである。 The present invention relates to a data communication system and a data communication method for collecting data of devices installed in a store via a network.
　近年、スーパーマーケットやコンビニエンスストア等の店舗に設置されたショーケースや空気調和機等の機器の計測データを遠隔監視するシステムが開発されてきている。この場合、店舗に設置された機器の各種計測データは当該店舗の店舗コントローラが一定間隔で収集している。遠隔監視システムは店舗コントローラに要求し、当該店舗コントローラが収集したデータをネットワークで接続された遠隔監視サーバにダウンロードして保存する。そして、ユーザはブラウザ等を介して遠隔監視サーバ上のデータを参照できるようにしている。 In recent years, systems have been developed that remotely monitor measurement data of equipment such as showcases and air conditioners installed in stores such as supermarkets and convenience stores. In this case, various measurement data of the devices installed in the store are collected at regular intervals by the store controller of the store. The remote monitoring system requests the store controller and downloads and stores the data collected by the store controller to a remote monitoring server connected via a network. The user can refer to data on the remote monitoring server via a browser or the like.
　このとき、常時接続形式のネットワークで接続された店舗コントローラの場合は、定期的に全てのデータを収集してデータベース等で管理することが可能であるが、パケット課金等のネットワークで接続された店舗コントローラの場合には、データ収集に必要となる通信料金が問題となって来る。 At this time, in the case of a store controller connected by a network of a constant connection type, it is possible to collect all data periodically and manage it in a database or the like, but stores connected by a network such as packet charging In the case of a controller, the communication fee required for data collection becomes a problem.
　ここで、例えば特許文献１では、Ｗｅｂブラウザ等で参照するページ情報を、クライアントＰＣとサーバＰＣにキャッシュとして保持し、サーバＰＣとクライアントＰＣ間のデータ通信量を削減していた。 Here, for example, in Patent Document 1, page information referred to by a Web browser or the like is held as a cache in the client PC and the server PC to reduce the amount of data communication between the server PC and the client PC.
　即ち、特許文献１では、クライアントＰＣ側で保持しているキャッシュデータと同一のデータを同一のＩＤを付与してサーバＰＣ側で管理し、クライアントＰＣから新たなデータの要求が発生した場合には、当該要求されたデータがキャッシュに存在しないデータであった場合に、新規に取得したデータとキャッシュに存在している全データとの差分を計算し、その差分データのサイズが最も小さいものをクライアントＰＣ側に返す。 That is, in Patent Document 1, when the same data as the cache data held on the client PC side is assigned with the same ID and managed on the server PC side, a new data request is generated from the client PC. When the requested data is not in the cache, the difference between the newly acquired data and all the data in the cache is calculated, and the smallest difference data size is calculated by the client. Return to PC side.
　そして、クライアントＰＣでは受信した差分データとキャッシュ上のデータから実データを再構成し、利用できるようにしていた。 And the client PC reconstructed the actual data from the received difference data and the data on the cache so that it can be used.
特開２００７－２９９０１９号公報JP 2007-299019 A
　しかしながら、係る従来の通信方式では、クライアントＰＣは自らのキャッシュに保持されたデータと全く同一のデータが存在しない場合には必ずサーバＰＣにデータ要求を行うことになる。また、サーバＰＣはクライアントＰＣと同一のデータをキャッシュに保持して管理しておく必要がある。更に、サーバＰＣは新規のデータをクライアントＰＣに返す際、キャッシュの全てのデータとの差分を計算する必要がある等の問題があった。 However, in such a conventional communication method, the client PC always makes a data request to the server PC when there is no data identical to the data held in its own cache. Further, the server PC needs to store and manage the same data as the client PC in a cache. Further, when the server PC returns new data to the client PC, there is a problem that it is necessary to calculate a difference from all the data in the cache.
　本発明は、係る従来の技術的課題を解決するために成されたものであり、比較的簡単な構成で遠隔監視システムと店舗コントローラ間の通信量及び料金を削減することができるデータ通信システム、及び、データ通信方法を提供するものである。 The present invention has been made to solve the conventional technical problems, and is a data communication system capable of reducing the communication amount and the charge between the remote monitoring system and the store controller with a relatively simple configuration, A data communication method is also provided.

　以下、本発明の実施の形態について、詳細に説明する。図１において、実施例のデータ通信システムは、スーパーマーケットやコンビニエンスストア等の店舗に設置された店舗コントローラ１、及び、店舗コントローラ２と、遠隔監視サーバとなる遠隔監視システム３と、クライアントとなるサービス担当者等のユーザクライアント４とから構築される。
　また、本実施の形態では接続機器コントローラとして店舗コントローラを想定した場合を記載するが、これに限られるものではなく、遠隔監視の対象となるコントローラであれば本発明を適用することができる。その他の例として、図８はバッテリーコントローラ１０１を遠隔監視する場合の遠隔監視システムとバッテリーコントローラとの通信シーケンスを示している。 Hereinafter, embodiments of the present invention will be described in detail. In FIG. 1, a data communication system according to an embodiment includes a store controller 1 and a store controller 2 installed in a store such as a supermarket or a convenience store, a remote monitoring system 3 serving as a remote monitoring server, and a service person serving as a client. It is constructed from the user client 4 such as a person.
Moreover, although the case where a store controller is assumed as the connected device controller is described in this embodiment, the present invention is not limited to this and can be applied to any controller that is a target of remote monitoring. As another example, FIG. 8 shows a communication sequence between the remote monitoring system and the battery controller when the battery controller 101 is remotely monitored.
　各店舗コントローラ１、２は、当該店舗に設置されたショーケースや空調機等の全機器から一定の間隔でデータ（機器の温度情報や警報情報等を含む運転状態に関するデータ）を収集し、保存している。 Each store controller 1, 2 collects and stores data (data related to the operating state including temperature information and alarm information of the device) at regular intervals from all devices such as showcases and air conditioners installed in the store. is doing.
　遠隔監視システム３は、その機能としてＷｅｂアプリケーション６、データベース７、定時データ収集処理プロセス８、ファイルシステム９、及び、手動データ収集処理プロセス１１を備えており、Ｗｅｂアプリケーション６とデータベース７間、定時データ収集処理プロセス８とデータベース７間、及び、手動データ収集処理プロセス９とデータベース７間はそれぞれデータベースアクセスによりそれぞれ接続され、Ｗｅｂアプリケーション６と定時データ収集処理プロセス８間、及び、Ｗｅｂアプリケーション６と手動データ収集処理プロセス９間はリモートメソッド呼び出しにより接続され、ファイルシステム１１と手動データ収集処理プロセス９間はファイルアクセスにより接続されている。 The remote monitoring system 3 includes a Web application 6, a database 7, a scheduled data collection process 8, a file system 9, and a manual data collection process 11 as its functions. The collection process 8 and the database 7 and the manual data collection process 9 and the database 7 are connected by database access, respectively, and between the Web application 6 and the scheduled data collection process 8 and between the Web application 6 and the manual data. The collection process 9 is connected by calling a remote method, and the file system 11 and the manual data collection process 9 are connected by file access.
　店舗コントローラ２は常時接続方式にて遠隔監視システム３の定時データ収集処理プロセス８にソケット(socket)接続されている。また、店舗コントローラ１はパケット接続方式にて遠隔監視システム３の手動データ収集処理プロセス９にソケット(socket)接続されている。そして、遠隔監視システム３のＷｅｂアプリケーション６にユーザクライアント４がＷｅｂブラウザ等によりＨＴＴＰプロトコルで接続される。 The store controller 2 is connected to the scheduled data collection process 8 of the remote monitoring system 3 in a socket by a constant connection method. Further, the store controller 1 is connected to the manual data collection processing process 9 of the remote monitoring system 3 by a socket by a packet connection method. Then, the user client 4 is connected to the Web application 6 of the remote monitoring system 3 by the HTTP protocol by a Web browser or the like.
　常時接続方式の店舗コントローラ２が収集し、保存している機器の全てのデータは、定時データ収集処理プロセス８により定期的に遠隔監視システム３が収集し、データベース７に保存する。ユーザクライアント４は、ＷｅｂブラウザからＷｅｂアプリケーション６経由で遠隔監視システム３のデータベース７に保存されているデータを検索し、参照することができる。 All data of the equipment collected and stored by the store controller 2 of the always-on connection method is periodically collected by the remote monitoring system 3 by the scheduled data collection processing process 8 and stored in the database 7. The user client 4 can search and refer to data stored in the database 7 of the remote monitoring system 3 via the Web application 6 from the Web browser.
　他方、パケット接続方式の店舗コントローラ１が収集し、保存している機器のデータは、ユーザクライアント４からのデータ参照要求があったときのみ、ユーザクライアント４が指定した収集条件のデータのみを遠隔監視システム３が手動データ収集処理プロセス９により店舗コントローラ１から収集し、ファイルシステム１１にファイルとして保存する。遠隔監視システム３はファイルシステム１１に保存したファイルからユーザクライアント４が要求指定した収集条件に合致したデータをＷｅｂアプリケーション６経由でユーザクライアント４に返信して提供する。ユーザクライアント４は、Ｗｅｂブラウザで当該データを参照することができるように構成されている。 On the other hand, the device data collected and stored by the packet connection type store controller 1 is remotely monitored only when the data reference request from the user client 4 is received, and only the data of the collection conditions designated by the user client 4 is remotely monitored. The system 3 collects from the store controller 1 by the manual data collection process 9 and stores it as a file in the file system 11. The remote monitoring system 3 provides data that matches the collection conditions requested and specified by the user client 4 from the file stored in the file system 11 to the user client 4 via the Web application 6 and provides it. The user client 4 is configured so that the data can be referred to by a Web browser.
　次に図２は、図１の遠隔監視システム３がパケット接続方式の店舗コントローラ１に対し、データ収集条件を指定してデータを取得する際の通信シーケンスを示している。図２のＡ（上段）は、遠隔監視システム３からデータの収集条件（機器の端末ＩＤ、収集期間、収集間隔等）のみを指定してデータを収集する場合であり、遠隔監視システム３から収集条件のみを指定してデータ取得の要求が成されると、店舗コントローラ１は収集条件に適合するデータを遠隔監視システム３に転送する。 Next, FIG. 2 shows a communication sequence when the remote monitoring system 3 of FIG. 1 acquires data by specifying data collection conditions for the packet connection type store controller 1. A (upper) in FIG. 2 is a case where data is collected from the remote monitoring system 3 by specifying only data collection conditions (device terminal ID, collection period, collection interval, etc.). When a request for data acquisition is made by specifying only the conditions, the store controller 1 transfers data that meets the collection conditions to the remote monitoring system 3.
　一方、図２のＢ（下段）は、遠隔監視システム３からでの収集条件に併せて収集済み条件も指定してデータを収集する場合であり、遠隔監視システム３から収集条件に併せて収集済み条件も指定してデータ取得の要求が成されると、店舗コントローラ１は収集条件に適合し、且つ、収集済み条件には適合しないデータのみを保存しているデータ中から収集し、遠隔監視システム３に転送する。 On the other hand, B (lower) in FIG. 2 is a case where data is collected by specifying the collected condition in addition to the collecting condition from the remote monitoring system 3, and has been collected from the remote monitoring system 3 according to the collecting condition. When a data acquisition request is made by specifying the conditions, the store controller 1 collects only the data that conforms to the collection conditions and does not conform to the collected conditions from the stored data. Forward to 3.
　遠隔監視システム３は何れの場合も、店舗コントローラ１から受信したデータにＩＤを付与してファイルシステム１１にファイルとして保存する。 In any case, the remote monitoring system 3 assigns an ID to the data received from the store controller 1 and stores it in the file system 11 as a file.
　ここで、図５は遠隔監視システム３がユーザクライアント４からのデータ参照要求に応じて店舗コントローラ１から収集し、保存したデータのファイルとを管理するデータ収集結果管理テーブルを示している。このデータ収集結果管理テーブルは遠隔監視システム３のデータベース７に保存されている。 Here, FIG. 5 shows a data collection result management table in which the remote monitoring system 3 manages the data files collected and stored from the store controller 1 in response to a data reference request from the user client 4. This data collection result management table is stored in the database 7 of the remote monitoring system 3.
　図５においてデータ管理ＩＤとは、店舗コントローラ１から収集し、保存したファイルの保存先を管理するＩＤ、収集開始時刻とは店舗コントローラ１が機器のデータを収集した際の時刻である計測時刻に対してユーザクライアント４が参照したい最初の時刻、収集終了時刻とは同様にユーザクライアント４が参照したい最後の時刻、収集間隔とは店舗コントローラ１が一定の間隔（ユーザクライアント４が指定可能な最小間隔、例えば実施例では１０秒間隔等）で収集する機器のデータに対して、ユーザクライアント４が参照したい間隔（例えば６０秒間隔等）、端末ＩＤ一覧とは店舗コントローラ１が収集した機器のデータに対して、ユーザクライアント４が参照したい機器のＩＤの一覧をそれぞれ示す。 In FIG. 5, the data management ID is an ID for managing the storage destination of the file collected and stored from the store controller 1, and the collection start time is a measurement time that is the time when the store controller 1 collects the device data. On the other hand, the first time that the user client 4 wants to refer to and the collection end time are the same as the last time that the user client 4 wants to refer to, and the collection interval is the fixed interval (the minimum interval that the user client 4 can specify). For example, for device data collected at intervals of 10 seconds in the embodiment, for example, an interval that the user client 4 wants to refer to (for example, intervals of 60 seconds), the terminal ID list is the device data collected by the store controller 1. On the other hand, a list of IDs of devices that the user client 4 wants to refer to is shown.
　尚、機器のＩＤとは前述した如く遠隔監視システム３に接続された全店舗コントローラ１、２のそれぞれに接続された全ての機器に対して一意に決定されて付与されたＩＤである。そして、ユーザクライアント４は、上記収集開始時刻、収集終了時刻、収集間隔、及び、端末ＩＤを指定して収集条件とし、遠隔監視システム３にデータ参照要求を行うことになる。 The device ID is an ID uniquely determined and assigned to all devices connected to all the store controllers 1 and 2 connected to the remote monitoring system 3 as described above. The user client 4 makes a data reference request to the remote monitoring system 3 by specifying the collection start time, collection end time, collection interval, and terminal ID as a collection condition.
　次に、遠隔監視システム３は、図５のデータ収集結果管理テーブルを、以下の規則に基づいて管理する。即ち、
（イ）．ユーザクライアント４からデータ参照要求が成された際に、そのときのデータの収集条件とデータ管理ＩＤとを関連付けて登録する。
（ロ）．データ管理ＩＤは、店舗コントローラ１からデータをダウンロードし、保存した際に新規に発行される。
（ハ）．データの新規の収集条件と全く条件が同一の既存の収集条件が登録されている場合は、新規登録は行わない。
（ニ）．データの新規の収集条件を完全に包含する既存の収集条件が存在していたときは、当該既存の収集条件と関連付けられているデータ管理ＩＤと同じＩＤを付与して新規の収集条件をデータ収集結果管理テーブルに追加登録する。
（ホ）．既存のダウンロードデータと新規のダウンロードデータの組み合わせで構成される収集条件に対しては、双方のデータ管理ＩＤを付けて管理する。 Next, the remote monitoring system 3 manages the data collection result management table of FIG. 5 based on the following rules. That is,
(I). When a data reference request is made from the user client 4, the data collection conditions and the data management ID at that time are registered in association with each other.
(B). The data management ID is newly issued when data is downloaded from the store controller 1 and stored.
(C). If an existing collection condition that is exactly the same as the new data collection condition is registered, new registration is not performed.
(D). When there is an existing collection condition that completely includes the new data collection condition, the same ID as the data management ID associated with the existing collection condition is assigned to collect the new collection condition. Add to the result management table.
(E). A collection condition composed of a combination of existing download data and new download data is managed by attaching a data management ID of both.
　次に、図３はユーザクライアント４からのデータ参照要求に対して、遠隔監視システム３が店舗コントローラ１からデータを収集する際の判断方法を示すフローチャート、図４は店舗コントローラ１におけるデータの作成処理を示すフローチャートである。図３のステップＳ１でユーザクライアント４からの新規の収集条件を指定したデータの参照要求を受信すると、遠隔監視システム３はステップＳ２で新規の収集条件と図５のデータ収集結果管理テーブルに登録されている既存の収集条件とを比較し、新規の収集条件の一部を包含している既存の収集条件（データ）が存在しているか否かを判断する。 Next, FIG. 3 is a flowchart showing a determination method when the remote monitoring system 3 collects data from the store controller 1 in response to a data reference request from the user client 4, and FIG. 4 is a data creation process in the store controller 1. It is a flowchart which shows. When receiving a data reference request specifying a new collection condition from the user client 4 in step S1 of FIG. 3, the remote monitoring system 3 is registered in the new collection condition and the data collection result management table of FIG. 5 in step S2. The existing collection conditions are compared with each other, and it is determined whether or not there is an existing collection condition (data) that includes a part of the new collection conditions.
　そして、一部をも包含している既存の収集条件が存在しない場合、即ち、当該新規の収集条件が既存の収集条件とは完全に異なっている場合、ステップＳ３で当該新規の収集条件のみを指定して店舗コントローラ１にデータ取得の要求を行う。 If there is no existing collection condition that includes a part, that is, if the new collection condition is completely different from the existing collection condition, only the new collection condition is determined in step S3. It designates and requests the store controller 1 to acquire data.
　店舗コントローラ１は遠隔監視システム３から収集条件のみを指定したデータ取得の要求があると、図４のステップＳ１０で自らが保存しているデータ中の当該データが当該収集条件に一致するか否かを判断する。一致していればステップＳ１１に進み、今度は収集済み条件は指定されているか否かを判断し、ここでは指定されていないのでステップＳ１３に進み、自らが保存しているデータ中から当該データを収集する。そして、ステップＳ１４で全てのデータを収集したか否か判断し、収集が済んでいなければステップＳ１０に戻ってこれを繰り返す。そして、当該収集条件に一致する全てのデータを収集し終えたら、当該データを遠隔監視システム３に送信する。 When there is a data acquisition request specifying only the collection condition from the remote monitoring system 3, the store controller 1 determines whether or not the data in the data stored by itself in step S10 in FIG. 4 matches the collection condition. Judging. If they match, the process proceeds to step S11. This time, it is determined whether or not the collected condition is specified. Since it is not specified here, the process proceeds to step S13, and the data is stored from the data stored by itself. collect. Then, in step S14, it is determined whether or not all data has been collected. If the data has not been collected, the process returns to step S10 to repeat this. Then, after collecting all data that matches the collection condition, the data is transmitted to the remote monitoring system 3.
　遠隔監視システム３は、このようにして店舗コントローラ１からデータを収集し、ファイルシステム１１（サーバ）に追加して保存する（図２のＡ）。そして、図３のステップＳ４で当該収集した新規のデータに対応した新規のデータ管理ＩＤを発行し、当該データ管理ＩＤを新規の収集条件とを関連付けて図５のデータ収集結果管理テーブルに追加する。 The remote monitoring system 3 collects data from the store controller 1 in this way, adds it to the file system 11 (server), and stores it (A in FIG. 2). Then, a new data management ID corresponding to the collected new data is issued in step S4 of FIG. 3, and the data management ID is associated with the new collection condition and added to the data collection result management table of FIG. .
　例えば、図５中の１行目のみにデータ管理ＩＤ「１」が付与された既存の収集条件が登録されている場合に、６行目の収集条件の参照要求があった場合がこれに相当する。この６行目の収集条件は１行目の収集条件と完全に異なっているので、この場合には新規のデータ管理ＩＤ「５」が新規に収集したファイルシステム１１内のデータに付与され、当該データ管理ＩＤ「５」に新規の収集条件が関連付けられてデータベース７のデータ収集結果管理テーブルに追加されている。 For example, when the existing collection condition with the data management ID “1” assigned to only the first line in FIG. 5 is registered, this corresponds to the case where there is a request to collect the collection condition on the sixth line. To do. Since the collection condition on the sixth line is completely different from the collection condition on the first line, a new data management ID “5” is assigned to the newly collected data in the file system 11 in this case, A new collection condition is associated with the data management ID “5” and added to the data collection result management table of the database 7.
　次に、図３のステップＳ２で新規の収集条件と既存の収集条件とが完全には異なっていない場合は、ステップＳ５に進んで新規の収集条件がデータ収集結果管理テーブルに登録されている既存の収集条件のうちの何れかと同一か否かを判断する。この場合の同一の条件とは、既存の収集開始時刻が新規の収集開始時刻と同一、且つ、既存の収集終了時刻が新規の収集終了時刻と同一、且つ、新規の収集間隔が既存の収集間隔と同一、且つ、既存の端末ＩＤ一覧が新規の端末ＩＤ一覧と同一であることである。 Next, when the new collection condition and the existing collection condition are not completely different in step S2 of FIG. 3, the process proceeds to step S5 and the existing collection condition is registered in the data collection result management table. It is determined whether it is the same as any of the collection conditions. The same condition in this case is that the existing collection start time is the same as the new collection start time, the existing collection end time is the same as the new collection end time, and the new collection interval is the existing collection interval. And the existing terminal ID list is the same as the new terminal ID list.
　そして、新規の収集条件と同一の既存の収集条件が存在していた場合には、遠隔監視システム３は、店舗コントローラ１にデータ取得の要求を行うこと無く、当該既存の収集条件と関連付けられたデータ管理ＩＤに対応するデータを手動データ収集処理プロセス９によりファイルシステム１１から読み出し、Ｗｅｂアプリケーション６によりユーザクライアント４に提供する。従って、この場合には図５には新規の登録は行われない。 If there is an existing collection condition identical to the new collection condition, the remote monitoring system 3 is associated with the existing collection condition without requesting the store controller 1 to acquire data. Data corresponding to the data management ID is read from the file system 11 by the manual data collection process 9 and provided to the user client 4 by the Web application 6. Therefore, in this case, no new registration is performed in FIG.
　次に、図３のステップＳ５で新規の収集条件が既存の収集条件と同一では無い場合、ステップＳ６に進んで今度は新規の収集条件が既存の収集条件に完全に包含されるか否か判断する。この場合の完全包含の条件とは、既存の収集開始時刻が新規の収集開始時刻より早いか同一、且つ、既存の収集終了時刻が新規の収集終了時刻より遅いか同一、且つ、新規の収集間隔が既存の収集間隔の公倍数、且つ、既存の端末ＩＤ一覧に新規の端末ＩＤ一覧の全ての端末ＩＤが含まれていることである。 Next, when the new collection condition is not the same as the existing collection condition in step S5 of FIG. 3, the process proceeds to step S6, and it is determined whether or not the new collection condition is completely included in the existing collection condition. To do. The complete inclusion condition in this case is that the existing collection start time is earlier than or the same as the new collection start time, and the existing collection end time is later than or the same as the new collection end time, and a new collection interval. Is a common multiple of the existing collection interval, and the existing terminal ID list includes all the terminal IDs in the new terminal ID list.
　そして、新規の収集条件が既存の収集条件の何れかに包含される場合、ステップＳ７に進んで当該既存の収集条件と関連付けられたデータ管理ＩＤと共に当該新規の収集条件を図５のデータ収集結果管理データテーブルに登録する。そして、店舗コントローラ１にデータ取得の要求を行うこと無く、当該既存の収集条件と関連付けられたデータ管理ＩＤに対応してファイルシステム１１に保存されているデータ中から、当該新規の収集条件に合致するデータのみを抜粋し、Ｗｅｂアプリケーション６によりユーザクライアント４に提供する。 Then, when the new collection condition is included in any of the existing collection conditions, the process proceeds to step S7, and the new collection condition and the data collection result shown in FIG. Register in the management data table. And, without making a data acquisition request to the store controller 1, it matches the new collection condition from the data stored in the file system 11 corresponding to the data management ID associated with the existing collection condition. Only the data to be extracted is extracted and provided to the user client 4 by the Web application 6.
　例えば、図５中の１行目のみにデータ管理ＩＤ「１」が付与された既存の収集条件が登録されている場合に、２行目の収集条件の参照要求があった場合がこれに相当する。この２行目の収集条件は１行目の収集条件に包含されるので、この場合には既存のデータ管理ＩＤ「１」が新規の収集条件に関連付けられてデータベース７のデータ収集結果管理テーブルに追加されている。 For example, when the existing collection condition with the data management ID “1” assigned to only the first line in FIG. 5 is registered, this corresponds to the case where there is a reference request for the second line collection condition. To do. Since the collection condition of the second line is included in the collection condition of the first line, in this case, the existing data management ID “1” is associated with the new collection condition in the data collection result management table of the database 7. Have been added.
　図３のステップＳ６で新規の収集条件が既存の収集条件に完全には包含されない場合、即ち、同一でも完全に異なるでも無く、その一部が一致する場合はステップＳ８に進む。この一部一致の条件とは、既存の収集開始時刻が新規の収集開始時刻より早いか同一、又は、既存の収集終了時刻が新規の収集終了時刻より遅いか同一、又は、新規の収集間隔が既存の収集間隔の公倍数、又は、既存の端末ＩＤ一覧に新規の端末ＩＤ一覧の一部の端末ＩＤが含まれていることである。 If the new collection condition is not completely included in the existing collection condition in step S6 of FIG. 3, that is, if it is not the same or completely different and part of them coincides, the process proceeds to step S8. This partial match condition is that the existing collection start time is earlier or the same as the new collection start time, or the existing collection end time is later than or the same as the new collection end time, or the new collection interval is The common multiple of the existing collection interval or the existing terminal ID list includes some terminal IDs in the new terminal ID list.
　図３のステップＳ８で、遠隔監視システム３は当該新規の収集条件と、収集済み条件とを指定して店舗コントローラ１にデータ取得の要求を行う。尚、この収集済み条件とは、新規の収集条件と一部が一致する既存の収集条件のことである。 In step S8 of FIG. 3, the remote monitoring system 3 requests the store controller 1 to acquire data by specifying the new collection condition and the collected condition. The collected condition is an existing collection condition that partially matches the new collection condition.
　店舗コントローラ１は遠隔監視システム３から収集条件と収集済み条件を指定したデータ取得の要求があると、図４のステップＳ１０で自らが保存しているデータ中の当該データが当該収集条件に一致するか否かを判断する。一致していればステップＳ１１に進み、収集済み条件が指定されているか否かを判断し、ここでは指定されているのでステップＳ１２に進み、自らが保存しているデータ中の当該データが収集済み条件に一致するデータか否か判断する。そして、収集済み条件に一致するデータであった場合には、ステップＳ１４に進み、収集済み条件に一致しないデータである場合のみ、ステップＳ１３に進んで自らが保存しているデータ中から当該データを収集する。そして、ステップＳ１４で全てのデータを収集したか否か判断し、収集が済んでいなければステップＳ１０に戻ってこれを繰り返す。このようにして店舗コントローラ１は、新規の収集条件に合致するが、収集済み条件には合致しないデータのみを抜粋していく。そして、新規の収集条件に合致するが、収集済み条件には合致しない全てのデータを収集し終えたら、当該データを遠隔監視システム３に送信する。 When the store controller 1 receives a data acquisition request specifying the collection condition and the collected condition from the remote monitoring system 3, the data in the data stored in the store controller 1 in step S10 in FIG. 4 matches the collection condition. Determine whether or not. If they match, the process proceeds to step S11, and it is determined whether or not the collected condition is specified. Since it is specified here, the process proceeds to step S12, and the data in the data stored by itself has been collected. It is determined whether the data matches the condition. If the data matches the collected conditions, the process proceeds to step S14. Only when the data does not match the collected conditions, the process proceeds to step S13 and the data is stored from the data stored by itself. collect. Then, in step S14, it is determined whether or not all data has been collected. If the data has not been collected, the process returns to step S10 to repeat this. In this way, the store controller 1 extracts only data that matches the new collection condition but does not match the collected condition. Then, after collecting all data that matches the new collection condition but does not match the collected condition, the data is transmitted to the remote monitoring system 3.
　遠隔監視システム３は、このようにして店舗コントローラ１からデータを収集し、ファイルシステム１１（サーバ）に追加して保存する（図２のＢ）。そして、図３のステップＳ９で当該収集した新規のデータに対応した新規のデータ管理ＩＤを発行し、当該データ管理ＩＤと既存の収集条件に関連付けられたデータ管理ＩＤの双方を新規の収集条件と関連付けて図５のデータ収集結果管理テーブルに追加する。 The remote monitoring system 3 collects data from the store controller 1 in this way, adds it to the file system 11 (server), and stores it (B in FIG. 2). Then, in step S9 of FIG. 3, a new data management ID corresponding to the collected new data is issued, and both the data management ID and the data management ID associated with the existing collection condition are set as the new collection condition. It associates and adds to the data collection result management table of FIG.
　例えば、図５中の１行目のみにデータ管理ＩＤ「１」が付与された既存の収集条件が登録されている場合に、３行目～５行目の収集条件の参照要求があった場合がこれに相当する。これらの収集条件は１行目の収集条件と一部が一致しているので、この場合には新規の収集条件と関連付けられたデータ管理ＩＤ「２」、「３」、「４」が新規に収集したファイルシステム１１内のデータに付与され、当該データ管理ＩＤ「２」、「３」、「４」とデータ管理ＩＤ「１」に新規の収集条件が関連付けられてデータベース７のデータ収集結果管理テーブルに追加されている（「１，２」、「１，３」、「１，４」）。 For example, when the existing collection condition with the data management ID “1” is registered only in the first line in FIG. 5, there is a request for reference to the collection condition in the third to fifth lines. Corresponds to this. Since these collection conditions partially match the collection conditions in the first row, in this case, the data management IDs “2”, “3”, and “4” associated with the new collection conditions are newly added. A new collection condition is associated with the data management ID “2”, “3”, “4” and the data management ID “1” assigned to the collected data in the file system 11, and the data collection result management of the database 7 is performed. It has been added to the table (“1, 2”, “1, 3”, “1, 4”).
　このように本発明では、遠隔監視システム３はユーザクライアント４のデータ参照要求に対し、既に店舗コントローラ１から収集して保存しているデータ中に存在しないデータのみを店舗コントローラ１から取得するので、遠隔監視システム３と店舗コントローラ１間の通信量並びに当該通信によって発生する料金を削減することが可能となる。 Thus, in the present invention, in response to the data reference request of the user client 4, the remote monitoring system 3 acquires only data that does not exist in the data already collected and stored from the store controller 1, from the store controller 1. It is possible to reduce the amount of communication between the remote monitoring system 3 and the store controller 1 and the charges generated by the communication.
　また、遠隔監視システム３はユーザクライアント４からデータ参照履歴の要求があった場合、既存の収集条件から収集済み条件一覧を作成し、ユーザクライアント４に提供する。図６はユーザクライアント４に提供される収集済み条件一覧を示している。尚、図６の一覧は図５のデータ収集結果管理テーブルに対応している。 Further, when a request for data reference history is received from the user client 4, the remote monitoring system 3 creates a collected condition list from the existing collection conditions and provides it to the user client 4. FIG. 6 shows a collected condition list provided to the user client 4. The list in FIG. 6 corresponds to the data collection result management table in FIG.
　ユーザクライアント４は提示された収集済み条件一覧中の任意の項目を選択することができる。遠隔監視システム３は、ユーザクライアント４により図６中の任意の項目が選択されると、当該項目に対応するデータ管理ＩＤに対応するデータを手動データ収集処理プロセス９によりファイルシステム１１から読み出し、Ｗｅｂアプリケーション６によりユーザクライアント４に提供する。図７は例えば図６の上から２行目の項目を選択した場合の再表示の実行結果を示している。 User client 4 can select any item in the list of collected conditions presented. When an arbitrary item in FIG. 6 is selected by the user client 4, the remote monitoring system 3 reads data corresponding to the data management ID corresponding to the item from the file system 11 by the manual data collection process 9, and Provided to the user client 4 by the application 6. FIG. 7 shows an execution result of re-display when, for example, the item on the second line from the top of FIG. 6 is selected.
　ユーザクライアント４には実際に店舗コントローラ１からデータをダウンロードした際の条件とは関係なく、過去に参照した収集条件のデータがそのまま遠隔監視システム３上に保存されているように見える。 In the user client 4, it appears that the collection condition data referred to in the past is stored in the remote monitoring system 3 as it is, regardless of the conditions when the data is actually downloaded from the store controller 1.
　このように、ユーザクライアント４は過去に遠隔監視システム３に参照要求した収集条件の履歴を一覧で参照することができるので、一覧に存在する収集条件に関しては、それを選択するのみで当該収集条件のデータを取得することができるようになり、著しい利便性の向上を図ることが可能となる。 As described above, the user client 4 can refer to the history of the collection conditions that have been requested to be referred to the remote monitoring system 3 in the past, so that the collection conditions existing in the list can be selected only by selecting the collection conditions. Data can be acquired, and it is possible to significantly improve convenience.
