Abstract

Provided are an information processing system and an information processing method which enable efficient recovery of an electronic device communicable with a management server, when various types of failures occur in the electronic device. According to the present invention, a control unit CPU of a sensor box SB-1 repeatedly receives a recovery data set from a management server SV at defined timings, and stores the recovery data set in a memory MR. Furthermore, when the control unit CPU determines, as a result of self-diagnosis, that a failure has occurred and the sensor box SB-1 is incommunicable with the management server SV, the sensor box SB-1 can autonomously recover from the failure without relying on the management server SV because the sensor box SB-1 is configured to try to recover from a failure on the basis of the latest recovery data set stored in the memory MR. Moreover, since the sensor box SB-1 becomes communicable with the management server SV over a network NW after succeeding in recovering from the failure, the sensor box SB-1 transmits a report log to the management server SV. The management server SV updates a database DB on the basis of the report log transmitted from the sensor box SB-1. In this way, the latest data about the success rate of a script for recovery from a failure that occurs in the sensor box SB-1 can be always obtained. Thus, as a result of repeatedly downloading the recovery data set at the defined timings, the probability that the sensor box SB-1 autonomously recovers is increased, the time and effort required for recovery works of a person such as a user or a service person are saved, and thereby, the cost is reduced.

Description

情報処理システム及び情報処理方法Information processing system and information processing method
　本発明は、電子機器の復旧を効率良く行える情報処理システム及び情報処理方法に関する。 The present invention relates to an information processing system and an information processing method that can efficiently restore an electronic device.
　監視カメラや小売店の電子レジスタなど、種々の電子機器がネットワークを介して管理サーバに接続されて情報のやりとりを行い、情報の集中管理が行われている。このような電子機器の使用中に何らかの障害が生じると、情報の集中管理を行えなくなるため迅速な復旧が望まれる。障害からの復旧の初動としては、電子機器を使用するユーザーが、取扱説明書等に従って復旧作業を行うことが多い。障害が比較的軽度であれば、復旧作業として再起動等を行うことで不具合のあるデータなどがリセットされ、容易に復旧を行うことができることもある。これに対し、障害が比較的重度であると、電子機器の復旧作業に不慣れなユーザーでは、復旧に手間取ることもある。そのような場合、障害の生じた電子機器のある現地にサービスマン等を派遣して復旧作業を行わせる必要があるが、それにより復旧までに多大なコストと時間がかかる。 A variety of electronic devices, such as surveillance cameras and electronic registers in retail stores, are connected to a management server via a network to exchange information and perform centralized management of information. If any failure occurs during the use of such an electronic device, centralized management of information cannot be performed, and a quick recovery is desired. As an initial action for recovery from a failure, a user who uses an electronic device often performs recovery work in accordance with an instruction manual or the like. If the failure is relatively mild, performing a recovery operation as a recovery operation may reset defective data or the like, and may be easily recovered. On the other hand, if the failure is relatively severe, a user who is unfamiliar with the restoration work of the electronic device may take time to restore. In such a case, it is necessary to dispatch a service person or the like to the site where the faulty electronic device is located, so that the restoration work is performed.
　特許文献１には、親機と子機とを接続可能な無線テレメータシステムが開示されている。特許文献１によれば、例えば親機又は子機に対して落雷等のトラブルが発生して、その回路基板等の故障が発生した場合、復旧のために、故障した親機又は子機の回路基板等から必要情報を読み出そうとしても、回路基板自体が動作しないため読み出せないことが多いとされる。かかる場合には、まず、回路基板を部品交換して復旧を行う必要があるが、交換された新たな回路基板等に記憶させるバックアップとしての必要情報を、予め外部機器に記憶しておき、ネットワークを介して親機又は子機に読み出すことはできる。しかしながら、バックアップのための専用の外部機器を設けることはコストがかかり、また常に外部機器と通信可能な状態が確保されるとは限らない。そこで、予め必要情報を親機又は子機の不揮発性メモリに記録しておき、故障が生じた場合、故障した親機又は子機から不揮発性メモリを取り外して、修理した親機又は子機に装着することで、バックアップを確保することなく、また外部機器との通信が不能であっても無線テレメータシステムの復旧を可能とすることが示されている。 Patent Document 1 discloses a wireless telemeter system capable of connecting a master unit and a slave unit. According to Patent Document 1, for example, when a trouble such as a lightning strike occurs in a parent device or a child device and a failure occurs in the circuit board or the like, the circuit of the failed parent device or child device is used for recovery. Even if it is attempted to read out necessary information from a board or the like, it is often impossible to read out because the circuit board itself does not operate. In such a case, it is necessary to first replace the circuit board and restore it. However, necessary information as a backup to be stored in the replaced new circuit board or the like is stored in an external device in advance, and the network It can be read out to the parent device or the child device via the. However, providing a dedicated external device for backup is costly and does not always ensure a state in which communication with the external device is possible. Therefore, necessary information is recorded in advance in the non-volatile memory of the master unit or slave unit, and if a failure occurs, the nonvolatile memory is removed from the faulty master unit or slave unit, and the repaired master unit or slave unit is stored.

　しかしながら、特許文献１の技術により復旧作業が容易になるとしても、復旧に際しては依然として電子機器に対して人手を介した作業を行う必要があり、手間がかかる。又、電子機器によっては、不揮発性メモリの交換だけでは復旧が困難な場合もある。これに対し、例えば管理サーバからネットワークを介して、障害が生じた電子機器を遠隔操作して障害からの復旧を行わせる技術も開発されている。障害の発生は、ネットワークを介してなされる電子機器からの通知によって管理サーバに知らせることができるので、通知を受けた管理サーバは直ちに必要な処理を行えるから、迅速且つ効率良く電子機器の復旧を行える。しかしながら、電子機器の通信に関わる部位に障害が生じた場合、管理サーバに通知することができないから、電子機器の遠隔操作も不可能になる。 However, even if the recovery work is facilitated by the technique of Patent Document 1, it is still necessary to manually perform operations on the electronic device during the recovery. Also, depending on the electronic device, recovery may be difficult only by replacing the nonvolatile memory. On the other hand, for example, a technology has been developed in which an electronic device in which a failure has occurred is remotely operated from a management server via a network to recover from the failure. The occurrence of a failure can be notified to the management server by a notification from the electronic device via the network, so that the management server that has received the notification can immediately perform the necessary processing, so that the electronic device can be recovered quickly and efficiently. Yes. However, when a failure occurs in a part related to communication of the electronic device, the management server cannot be notified, and thus the remote operation of the electronic device is also impossible.
　更に、同種の電子機器であっても、製造時期に応じて異なるバージョンのファームウエア等を搭載していることがあるが、それにより障害の内容が変わってくる恐れがある。障害の内容が変われば復旧の手順なども変わるので、全ての障害に対して画一化した処理により復旧を行うことは困難といえる。従って、電子機器に生じる種々の障害に対して、いかに効率良く且つ自律的に復旧させることができるかが大きな課題となっている。 Furthermore, even with the same type of electronic equipment, different versions of firmware may be installed depending on the manufacturing time, but the content of the failure may change accordingly. If the content of the failure changes, the recovery procedure and the like also change. Therefore, it can be said that it is difficult to perform recovery using a uniform process for all failures. Therefore, how to efficiently and autonomously recover various failures that occur in electronic devices is a major issue.

　以下、本発明にかかる実施形態を図面に基づいて説明する。図１は、本実施形態における情報処理システム又は情報処理方法を実現する介護支援システムの全体構成を示す図である。本実施形態における介護支援システムは、見守り対象である被監視者（以下、対象者という）Ｏｂの状態を、それぞれ対応するセンサボックスＳＢにより検知することで対象者Ｏｂを見守って、介護を支援する機能を有するものである。尚、センサボックスＳＢは、限られたコンピュータ資源を持つものであると好ましい。 Hereinafter, embodiments according to the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating an overall configuration of a care support system that realizes an information processing system or an information processing method according to the present embodiment. The care support system according to the present embodiment supports the care by watching the target person Ob by detecting the state of the monitored person (hereinafter referred to as the target person) Ob that is the object of monitoring by the corresponding sensor box SB. It has a function. The sensor box SB preferably has limited computer resources.
　このような介護支援システムＭＳは、例えば、図１に示すように、対象者の居室にそれぞれ備えられたセンサボックスＳＢ（ＳＢ－１～ＳＢ－４）と、管理サーバＳＶと、固定端末装置ＳＰと、介護士がそれぞれ管理する携帯端末ＴＡ（ＴＡ－１、ＴＡ－２）とを有し、これらは、有線や無線で、ＬＡＮ（Ｌｏｃａｌ　Ａｒｅａ　Ｎｅｔｗｏｒｋ）、電話網およびデータ通信網等の網（ネットワーク、通信回線）ＮＷを介して通信可能に接続されている。ネットワークＮＷには、通信信号を中継する例えばリピーター、ブリッジ、ルーターおよびクロスコネクト等の中継機が備えられても良い。図１に示す例では、これら複数のセンサボックスＳＢ－１～ＳＢ－４、管理サーバＳＶ、固定端末装置ＳＰおよび複数の携帯端末ＴＡ－１、ＴＡ－２は、アクセスポイントＡＰを含む無線ＬＡＮ（例えばＩＥＥＥ８０２．１１規格に従ったＬＡＮ等）ＮＷによって互いに通信可能に接続されている。センサボックスＳＢは、電子機器の一例に相当する。 Such a care support system MS includes, for example, as shown in FIG. 1, a sensor box SB (SB-1 to SB-4), a management server SV, and a fixed terminal device SP respectively provided in the subject person's room. And mobile terminals TA (TA-1, TA-2) managed by caregivers, which are wired and wireless, such as LAN (Local Area Network), telephone network and data communication network ( Network, communication line) are communicably connected via NW. The network NW may be provided with relays such as repeaters, bridges, routers, and cross-connects that relay communication signals. In the example shown in FIG. 1, the plurality of sensor boxes SB-1 to SB-4, the management server SV, the fixed terminal device SP, and the plurality of portable terminals TA-1 and TA-2 are connected to a wireless LAN (including an access point AP ( For example, a LAN conforming to the IEEE 802.11 standard) is connected to be communicable with each other via an NW. The sensor box SB corresponds to an example of an electronic device.
　対象者Ｏｂは、例えば、病気や怪我等によって看護を必要とする者や、身体能力の低下等によって介護を必要とする者や、一人暮らしの独居者等である。特に、早期発見と早期対処とを可能にする観点から、対象者Ｏｂは、例えば異常状態等の所定の不都合な事象がその者に生じた場合にその発見を必要としている者であることが好ましい。このため、介護支援システムＭＳは、対象者Ｏｂの種類に応じて、病院、老人福祉施設および住戸等の建物に好適に配設される。図１に示す例では、介護支援システムＭＳは、複数の対象者Ｏｂが入居する複数の居室ＲＭや、ナースステーションＳＴ等の複数の部屋を備える介護施設の建物に配設されている。 The target person Ob is, for example, a person who needs nursing due to illness or injury, a person who needs care due to a decrease in physical ability, or a single person living alone. In particular, from the viewpoint of enabling early detection and early action, it is preferable that the subject Ob is a person who needs the detection when a predetermined inconvenient event such as an abnormal state occurs in the person. . For this reason, the care support system MS is suitably arranged in a building such as a hospital, a welfare facility for the elderly, and a dwelling unit according to the type of the subject Ob. In the example illustrated in FIG. 1, the care support system MS is disposed in a building of a care facility including a plurality of rooms RM in which a plurality of target persons Ob move, and a plurality of rooms such as a nurse station ST.
　管理サーバＳＶは、ネットワークＮＷを介してセンサボックスＳＢと、固定端末ＳＰと、携帯端末ＴＡとに独立して通信する通信機能を備えている。管理サーバＳＶは、センサボックスＳＢから通知を受けて、イベントが生じた居室を担当する介護士の持つ携帯端末ＴＡ、及び／又は固定端末装置ＳＰに情報を提供する機能を有すると共に、センサボックスＳＢ－１の障害に際し、センサボックスＳＢに必要な復旧データセット（復旧情報）を提供する機能を有する。 The management server SV has a communication function for communicating independently with the sensor box SB, the fixed terminal SP, and the mobile terminal TA via the network NW. The management server SV has a function of receiving information from the sensor box SB and providing information to the mobile terminal TA and / or the fixed terminal device SP of the caregiver in charge of the room where the event has occurred, and the sensor box SB. -1 has a function of providing a recovery data set (recovery information) necessary for the sensor box SB in the event of a failure.
　更に管理サーバＳＶは、図１に示すようにデータベースＤＢを有している。データベースＤＢは、センサボックスＳＢ－１の障害に関する情報（センサボックスの機種毎の故障履歴、利用履歴、使用環境に関する情報を含む）を記録している。障害に関する情報は、各センサボックスＳＢからレポートログ（詳細は後述）が管理サーバＳＶに送信される度に更新される。管理サーバＳＶは、データベースＤＢ内から、センサボックスＳＢ毎に最適な復旧データセットを抽出できる。かかる復旧データセットは、センサボックスＳＢに応じたファームウェアとツール、復旧までの手順を示す復旧スクリプト群、復旧パターンテーブルを含んでいる。 Furthermore, the management server SV has a database DB as shown in FIG. The database DB records information relating to the failure of the sensor box SB-1 (including information relating to failure history, usage history, and usage environment for each sensor box model). Information on the failure is updated each time a report log (details will be described later) is transmitted from each sensor box SB to the management server SV. The management server SV can extract an optimal restoration data set for each sensor box SB from the database DB. Such a recovery data set includes firmware and tools corresponding to the sensor box SB, a recovery script group indicating a procedure up to recovery, and a recovery pattern table.
　図２は、センサボックスＳＢ－１用のパターンテーブルの一例である。パターンテーブルには、図２に示すように、適用する優先順位、スプリクト名、復旧トライ回数、前回復旧結果（成功であればＴＲＵＥ、失敗であればＦＡＬＳＥ）、復旧からの成功率がリストとなって示されている。パターンテーブルの優先順位は、復旧の成功率が高い順に昇順となっている。スプリクト名は、同梱された復旧スクリプト群に対応するものであると好ましい。尚、成功率の括弧内は、同機種であるセンサボックスＳＢ－１，ＳＢ－２の障害から復旧に成功したトータルの成功率である。パターンテーブルの内容は以上に限られず、少なくとも優先順位とスプリクト名とが対応づけられていれば足りる。 FIG. 2 is an example of a pattern table for the sensor box SB-1. In the pattern table, as shown in FIG. 2, the priority order to be applied, the name of the script, the number of recovery tries, the previous recovery result (TRUE if successful, FALSE if failed), and the success rate from recovery are listed. Is shown. The priority order of the pattern table is ascending order from the highest recovery success rate. The script name preferably corresponds to a bundled recovery script group. The parentheses in the success rate are the total success rates that have been successfully recovered from the failure of the sensor boxes SB-1 and SB-2 of the same model. The contents of the pattern table are not limited to the above, and it is sufficient that at least the priority order is associated with the script name.
　図３は、センサボックスＳＢのブロック図である。センサボックスＳＢは、対象者Ｏｂの居室ＲＭの天井や壁等にそれぞれ配置され、ネットワークＮＷを介して管理サーバＳＶ等と通信する通信機能を備えている。より具体的に、センサボックスＳＢは、例えばカメラＣＡと、ファームウェアやツールなどを記憶したメモリＭＲと、通信部ＩＦと、これらを司る制御部ＣＰＵとを備えている。尚、図１で示すセンサボックスＳＢ－１，ＳＢ－２は互いに同機種であって、センサボックスＳＢ－３，ＳＢ－４と異なる機種である。但し、センサボックスＳＢ－１，ＳＢ－２は異なるバージョンのファームウェアを有するものとする。 FIG. 3 is a block diagram of the sensor box SB. The sensor box SB is disposed on the ceiling or wall of the living room RM of the subject Ob, and has a communication function for communicating with the management server SV or the like via the network NW. More specifically, the sensor box SB includes, for example, a camera CA, a memory MR that stores firmware, tools, and the like, a communication unit IF, and a control unit CPU that controls them. The sensor boxes SB-1 and SB-2 shown in FIG. 1 are the same model as each other but different from the sensor boxes SB-3 and SB-4. However, the sensor boxes SB-1 and SB-2 are assumed to have different versions of firmware.
　メモリＭＲに格納されたプログラムを実行することで動作する制御部ＣＰＵは、カメラＣＡで対象者Ｏｂを撮影して、その画像から対象者Ｏｂの起床、離床、転倒、転落等を判別し、それに対応する対象者情報を、通信部ＩＦからネットワークＮＷを介して管理サーバＳＶに送信する機能を有する。又、制御部ＣＰＵは、後述するように規定のタイミングで繰り返し、センサボックスＳＢに障害が生じていないか診断(ヘルスチェックともいう)を行い、障害が生じていた場合、それに対応する障害情報を、同様にネットワークＮＷを介して管理サーバＳＶに送信する機能も有する。 The control unit CPU, which operates by executing a program stored in the memory MR, takes an image of the subject Ob with the camera CA, determines from the image the subject Ob's getting up, getting out of bed, falling, falling, etc. Corresponding target person information is transmitted from the communication unit IF to the management server SV via the network NW. In addition, the control unit CPU repeatedly performs diagnosis (also referred to as a health check) on the sensor box SB for any failure, as described later, and if a failure has occurred, displays the failure information corresponding to the failure. Similarly, it also has a function of transmitting to the management server SV via the network NW.
　センサボックスＳＢから対象者情報を受信した管理サーバＳＶは、ネットワークＮＷを介して、そのセンサボックスＳＢが備えられた部屋を担当する介護士ＮＳの持つ端末ＴＡに、対象者Ｏｂの起床、離床、転倒、転落等が生じた旨の対象者情報を送信し、かかる端末ＴＡは、対象者情報に応じて画面表示を行うようになっている。かかる画面を見た介護士ＮＳは、担当する対象者Ｏｂに何が生じたのか判断できるので、部屋に駆けつけるなどの対応を迅速に行うことができる。 The management server SV that has received the target person information from the sensor box SB wakes up, leaves the target person Ob to the terminal TA of the caregiver NS in charge of the room in which the sensor box SB is provided, via the network NW. Target person information indicating that a fall, a fall or the like has occurred is transmitted, and the terminal TA displays a screen according to the target person information. The caregiver NS who sees such a screen can determine what has happened to the subject Ob in charge, and can therefore quickly take action such as rushing to the room.
　このように、センサボックスＳＢは、部屋にいる対象者Ｏｂの状態を、昼夜を問わず監視し続けるものであるので、センサボックスＳＢに障害が生じた場合、対象者Ｏｂの状態の把握が困難となる恐れがある。一方、センサボックスＳＢを比較的短期間毎にメンテナンスすれば、障害が生じる恐れを低下させることはできるが、手間とコストがかかる。そこで、規定のタイミングで繰り返し、センサボックスＳＢが正常に機能しているかを診断し、その結果障害が生じたと判断した場合には、直ちに必要な処理を行うことが望ましいといえる。 Thus, since the sensor box SB continues to monitor the state of the subject Ob in the room regardless of day or night, it is difficult to grasp the state of the subject Ob when the sensor box SB fails. There is a risk of becoming. On the other hand, if the sensor box SB is maintained at relatively short intervals, the risk of failure can be reduced, but it takes effort and cost. Therefore, it can be said that it is desirable to perform the necessary processing immediately when it is diagnosed whether the sensor box SB is functioning normally repeatedly at a specified timing and as a result it is determined that a failure has occurred.
　図４は、センサボックスＳＢ－１が正常に機能しているかを診断し、その結果障害が生じたと判断した場合に行う処理を示す梯子チャートである。ここでは、管理サーバＳＶとセンサボックスＳＢ－１とのデータのやりとりを示しているが、その他のセンサボックスとも同様なデータのやりとりが行われる。 FIG. 4 is a ladder chart showing processing performed when the sensor box SB-1 is diagnosed as functioning normally and it is determined that a failure has occurred as a result. Here, data exchange between the management server SV and the sensor box SB-1 is shown, but the same data exchange is performed with other sensor boxes.
　まず図４のステップＳ１０１において、管理サーバＳＶは、データベースＤＢからセンサボックスＳＢ－１用の最新である復旧データセットを読み出す。規定のタイミングで繰り返し、かかる復旧データセットは管理サーバＳＶからセンサボックスＳＢ－１にダウンロードされる（ｃ１１）。センサボックスＳＢ－１の制御部ＣＰＵは、ステップＳ１０２で、ダウンロードした復旧データセットをメモリＭＲに記憶する。メモリＭＲ中で、ダウンロードした復旧データセットは、それ以前の復旧データセットに上書きされても良いし、それ以前の復旧データセットをバックアップ用に残しておいても良い。 First, in step S101 of FIG. 4, the management server SV reads the latest restoration data set for the sensor box SB-1 from the database DB. The recovery data set is repeatedly downloaded from the management server SV to the sensor box SB-1 at a predetermined timing (c11). In step S102, the control unit CPU of the sensor box SB-1 stores the downloaded restoration data set in the memory MR. In the memory MR, the downloaded recovery data set may be overwritten on the previous recovery data set, or the previous recovery data set may be left for backup.
　更に規定のタイミング（復旧データセットのダウンロードとは異なるタイミングでも良い）で、ステップＳ１０３で、センサボックスＳＢ－１の制御部ＣＰＵは、メモリＭＲから自己診断プログラムを呼び出して診断を実行する。ステップＳ１０４で、制御部ＣＰＵが、その診断結果によりセンサボックスＳＢ－１の各部の機能が正常であると判断した場合、フローはステップＳ１０２へと戻る。 Further, at a predetermined timing (may be a timing different from the download of the recovery data set), in step S103, the control unit CPU of the sensor box SB-1 calls the self-diagnostic program from the memory MR and executes diagnosis. In step S104, when the control unit CPU determines that the function of each unit of the sensor box SB-1 is normal based on the diagnosis result, the flow returns to step S102.
　一方、診断結果によりセンサボックスＳＢ－１のいずれかに障害が発生したと判断した場合、制御部ＣＰＵは、続くステップＳ１０５で、通信部ＩＦを介して管理サーバＳＶと通信可能か否かを判断する。通信可能と判断すれば、制御部ＣＰＵは管理サーバＳＶに障害が生じた旨の通知を行う（ｃ１２）。これに応じて管理サーバＳＶは、ステップＳ１０６で、データベースＤＢからセンサボックスＳＢ－１用の最新である復旧データセットを読み出す。読み出された復旧データセットは、管理サーバＳＶからセンサボックスＳＢ－１にダウンロードされる（ｃ１３）。 On the other hand, when it is determined that a failure has occurred in any of the sensor boxes SB-1 based on the diagnosis result, the control unit CPU determines whether or not communication with the management server SV is possible via the communication unit IF in subsequent step S105. To do. If it is determined that communication is possible, the control unit CPU notifies the management server SV that a failure has occurred (c12). In response to this, the management server SV reads the latest restoration data set for the sensor box SB-1 from the database DB in step S106. The read recovery data set is downloaded from the management server SV to the sensor box SB-1 (c13).
　更に制御部ＣＰＵは、ステップＳ１０７で、ダウンロードした復旧データセットに基づいて、センサボックスＳＢ－１の障害からの復旧処理を試みる。ダウンロードした復旧データセットは最新であり、例えば図２に示すパターンテーブルが含まれているものとする。ここで、制御部ＣＰＵは、パターンテーブルを参照し、最も優先順位が高いスプリクト（図２の例では優先順位０：ｒｅｓ０１８Ａ．ｓｈ）を、復旧データセットに同梱された復旧スプリクト群から選定し、これに従って最初の復旧処理を行う。 Further, in step S107, the control unit CPU attempts a recovery process from the failure of the sensor box SB-1 based on the downloaded recovery data set. It is assumed that the downloaded recovery data set is the latest and includes, for example, the pattern table shown in FIG. Here, the control unit CPU refers to the pattern table and selects the script with the highest priority (priority 0: res018A.sh in the example of FIG. 2) from the recovery script group bundled with the recovery data set. According to this, the first recovery process is performed.
　図５は、スプリクトに従って制御部ＣＰＵが行う復旧処理の一例を示すフローチャートである。まずステップＳ１０７ａで、制御部ＣＰＵは、クリーンインストールを行う場合には不要なファイルを削除し、ステップＳ１０７ｂで、復旧データセットに同梱されたファームウェア（バージョンｘｘ）の圧縮ファイルを解凍し、ステップＳ１０７ｃで、解凍したファイルをｙｙに配置し、ステップＳ１０７ｄで，新たなファームウェアの書き込みを実行する。尚、スプリクトとしては、例えばセンサボックスの再起動などもあるが、かかる場合、ファームウエアやツールは使用しないこととなる。 FIG. 5 is a flowchart showing an example of a recovery process performed by the control unit CPU according to the script. First, in step S107a, the control unit CPU deletes unnecessary files when performing a clean installation, and in step S107b, decompresses the compressed file of the firmware (version xx) bundled with the recovery data set, and then executes step S107c. Then, the decompressed file is placed in yy, and writing of new firmware is executed in step S107d. Note that the script includes, for example, restarting the sensor box. In such a case, firmware and tools are not used.
　その後、図４のステップＳ１０８で、制御部ＣＰＵは，自己診断プログラムを再度実行して、障害から復旧したか否かを判断する。まだ障害から復旧していないと判断した場合、制御部ＣＰＵは、更にステップＳ１１１で、パターンテーブルに示されたスプリクト全てを試みたか否か判断する。全てを試みていないと判断した制御部ＣＰＵは、ステップＳ１０７へとフローを戻し、次の優先順位のスプリクト（図２の例では優先順位１：ｒｅｓ０７４Ａ．ｓｈ）を、復旧データセットに同梱された復旧スプリクト群から選定し、これに従って次の復旧処理を行う。その後、再びステップＳ１０８で、制御部ＣＰＵは障害から復旧したか否かを判断する。 Thereafter, in step S108 of FIG. 4, the control unit CPU executes the self-diagnosis program again to determine whether or not the failure has been recovered. If it is determined that the failure has not yet been recovered, the control unit CPU further determines in step S111 whether or not all the scripts indicated in the pattern table have been tried. The control unit CPU that has determined that all has not been attempted returns the flow to step S107, and the next priority script (priority 1: res074A.sh in the example of FIG. 2) is included in the recovery data set. The next restoration process is performed according to this. Thereafter, in step S108 again, the control unit CPU determines whether or not the failure has been recovered.
　ステップＳ１１１で、全てのスクリプトに従って復旧処理を試みたにもかかわらず、復旧が行われなかったと判断されると（判定Ｙｅｓ）、自力復旧が困難となることを意味するので、制御部ＣＰＵは，ステップＳ１１２で、例えばサービスマンの作業など外部処理による復旧を待つこととなる。外部処理によって復旧した場合、制御部ＣＰＵは、フローをステップＳ１０９へと進めて、後述するレポートログを作成する。 In step S111, if it is determined that the recovery process has not been performed in spite of all the scripts being tried for the recovery process (determination Yes), it means that it is difficult to recover by itself. In step S112, for example, recovery by an external process such as a serviceman's work is awaited. In the case of recovery by external processing, the control unit CPU advances the flow to step S109 and creates a report log to be described later.
　一方、いずれかのスクリプトにて復旧に成功した場合、制御部ＣＰＵはステップＳ１０９で、レポートログを作成する。復旧履歴情報としてのレポートログとは、復旧がなされたセンサボックスＳＢ－１を特定するための機器情報（ここではセンサボックスのメーカー名、機種番号、シリアル番号、ファームウェアのバージョン情報等）と、センサボックスＳＢ－１の履歴情報（どのスプリクトが復旧に失敗し、またどのスクリプトが復旧に成功したかを示す成否データ、前回の障害からの復旧後の稼動時間、前回の再起動後の稼働時間等）と、使用環境情報（センサボックスＳＢ－１に接続されたネットワーク回線の種類や仕様、周囲の温度や湿度、障害が起きた時間等）を含んでいる。 On the other hand, if the recovery is successful with any script, the control unit CPU creates a report log in step S109. The report log as recovery history information includes device information (here, sensor box manufacturer name, model number, serial number, firmware version information, etc.) for identifying the sensor box SB-1 that has been recovered, History information of box SB-1 (success / failure data indicating which script failed to recover and which script was successfully recovered, operating time after recovery from previous failure, operating time after previous restart, etc. ) And usage environment information (type and specification of the network line connected to the sensor box SB-1, ambient temperature and humidity, time of failure, etc.).
　その後、制御部ＣＰＵは管理サーバＳＶに，作成したレポートログをアップロードする（ｃ１４）。管理サーバＳＶは、ステップＳ１１０で、入力したレポートログに基づいてデータベースＤＢを更新する。具体的には、履歴情報中の成否データに基づいて、センサボックスＳＢ－１に対応して、図２に示すパターンテーブルの成功率を計算し直す。その結果、スクリプトの優先順位が変わる場合、優先順位を入れ替えてデータベースＤＢに記憶する。以下、フローはステップＳ１０１へと戻り、このように更新された最新のデータベースＤＢから、管理サーバＳＶは復旧データセットを読み出すこととなる。 Thereafter, the control unit CPU uploads the created report log to the management server SV (c14). In step S110, the management server SV updates the database DB based on the input report log. Specifically, based on the success / failure data in the history information, the success rate of the pattern table shown in FIG. 2 is recalculated corresponding to the sensor box SB-1. As a result, when the priority order of the script changes, the priority order is changed and stored in the database DB. Thereafter, the flow returns to step S101, and the management server SV reads the recovery data set from the latest database DB updated in this way.
　次に、センサボックスＳＢ－１の制御部ＣＰＵが、ステップＳ１０５で、通信部ＩＦを介して管理サーバＳＶと通信不能と判断した場合について説明する。この場合、制御部ＣＰＵは、管理サーバＳＶから最新の復旧データセットをダウンロードすることはできない。そこで、制御部ＣＰＵは、ステップＳ１１３で、障害発生直前にダウンロードされメモリＭＲに記憶されていた復旧データセットを読み出して、そのパターンテーブルに基づいて、図５のフローに従ってセンサボックスＳＢ－１の障害からの復旧処理を試みる。 Next, a case will be described in which the control unit CPU of the sensor box SB-1 determines that communication with the management server SV is impossible via the communication unit IF in step S105. In this case, the control unit CPU cannot download the latest recovery data set from the management server SV. Therefore, in step S113, the control unit CPU reads the recovery data set downloaded immediately before the failure occurrence and stored in the memory MR, and based on the pattern table, the failure of the sensor box SB-1 is read out according to the flow of FIG. Attempt recovery from.
　その後、ステップＳ１１４で、制御部ＣＰＵは，自己診断プログラムを再度実行して、障害から復旧したか否かを判断する。まだ障害から復旧していないと判断した場合、制御部ＣＰＵは、更にステップＳ１１５で、パターンテーブルに示されたスプリクト全てを試みたか否か判断する。全てを試みていないと判断した制御部ＣＰＵは、ステップＳ１１３へとフローを戻し、次の優先順位のスプリクトを、メモリＭＲに記憶された復旧データセットの復旧スプリクト群から選定し、これに従って次の復旧処理を行う。その後、再びステップＳ１１４で、制御部ＣＰＵは障害から復旧したか否かを判断する。 Thereafter, in step S114, the control unit CPU executes the self-diagnosis program again and determines whether or not the failure has been recovered. If it is determined that the failure has not yet been recovered, the control unit CPU further determines in step S115 whether or not all the scripts indicated in the pattern table have been tried. The control unit CPU, which has determined that all have not been attempted, returns the flow to step S113, and selects the next priority script from the recovery script group of the recovery data set stored in the memory MR. Perform recovery processing. Thereafter, in step S114 again, the control unit CPU determines whether or not the failure has been recovered.
　ステップＳ１１５で、全てのスクリプトに従って復旧処理を試みたにもかかわらず、復旧が行われなかったと判断されると（判定Ｙｅｓ）、自力復旧が困難となることを意味するので、制御部ＣＰＵは，ステップＳ１１２で、例えばサービスマンの作業など外部処理による復旧を待つこととなる。外部処理によって復旧した場合、制御部ＣＰＵは、フローをステップＳ１０９へと進めて、上述したレポートログを作成する。 In step S115, if it is determined that the recovery process has not been performed even though the recovery process has been attempted in accordance with all the scripts (determination Yes), it means that it is difficult to recover by itself. In step S112, for example, recovery by an external process such as a serviceman's work is awaited. In the case of recovery by external processing, the control unit CPU advances the flow to step S109 and creates the above-described report log.
　本実施形態によれば、センサボックスＳＢ－１の制御部ＣＰＵが、規定のタイミングで繰り返し管理サーバＳＶから復旧データセットを受信して、メモリＭＲに記憶するようになっており、更に制御部ＣＰＵが自己診断した結果、障害が生じていると判断し、また管理サーバＳＶと通信不能であると判断した場合には、メモリＭＲに記憶された最新の復旧データセットに基づいて、障害からの復旧を試みるようにしているので、管理サーバＳＶに頼ることなくセンサボックスＳＢ－１が自律的に障害から復旧することができる。 According to this embodiment, the control unit CPU of the sensor box SB-1 repeatedly receives the recovery data set from the management server SV at a specified timing and stores it in the memory MR. As a result of self-diagnosis, it is determined that a failure has occurred, and if it is determined that communication with the management server SV is impossible, recovery from the failure is performed based on the latest recovery data set stored in the memory MR. Therefore, the sensor box SB-1 can autonomously recover from the failure without relying on the management server SV.
　更に、障害からの復旧に成功した後には，ネットワークＮＷを介して管理サーバＳＶと通信可能となっているので、センサボックスＳＢ－１は、レポートログを管理サーバＳＶに送信し、管理サーバＳＶは、センサボックスＳＢ－１から送信されたレポートログに基づいてデータベースＤＢを更新する。これにより、センサボックスＳＢ－１に生じた障害から復旧させるためのスプリクトの成功率について、常に最新のデータを入手できるから、その復旧データセットを規定のタイミングで繰り返しダウンロードすることで、センサボックスＳＢ－１が自律的に復旧する可能性が高まり、ユーザーやサービスマン等の人手を介して復旧作業を行う手間が省け、コスト削減につながる。 Furthermore, after successfully recovering from the failure, the sensor box SB-1 transmits a report log to the management server SV because the communication with the management server SV is possible via the network NW. Then, the database DB is updated based on the report log transmitted from the sensor box SB-1. As a result, the latest data on the success rate of the script for recovering from the failure that has occurred in the sensor box SB-1 can always be obtained. By repeatedly downloading the recovery data set at a specified timing, the sensor box SB -1 increases the possibility of autonomous recovery, saving the effort of performing recovery work through the manual operation of users, service personnel, etc., leading to cost reduction.
　尚、管理サーバＳＶは、センサボックスＳＢ－１から送信されたレポートログに基づいて、将来起こりえる障害を予測することもできる。例えば、管理サーバＳＶがレポートログの履歴情報に基づいて、センサボックスＳＢ－１は再起動後に７２時間以上経過すると障害が生じやすいと認識した場合、センサボックスＳＢ－１の再起動後、６０時間経過した時点でセンサボックスＳＢ－１に強制再起動をかける指示（推奨される処理に関する推奨情報）をセンサボックスＳＢ－１に送信すると好ましい。これに応じてセンサボックスＳＢ－１は、再起動（推奨される処理）を実行することで、障害の発生を未然に抑制できる。以上、管理サーバＳＶとセンサボックスＳＢ－１との間でのデータのやりとりを説明したが、その他のセンサボックスＳＢ－１～ＳＢ－４でも同様である。 The management server SV can also predict a failure that may occur in the future based on the report log transmitted from the sensor box SB-1. For example, if the management server SV recognizes that a failure is likely to occur after 72 hours or more after restarting the sensor box SB-1 based on the history information of the report log, 60 hours after restarting the sensor box SB-1 It is preferable to send an instruction (recommended information regarding recommended processing) for forcibly restarting the sensor box SB-1 to the sensor box SB-1 when the time has elapsed. In response to this, the sensor box SB-1 can suppress the occurrence of a failure by restarting (recommended processing). The data exchange between the management server SV and the sensor box SB-1 has been described above, but the same applies to the other sensor boxes SB-1 to SB-4.
　図６は、別な実施形態にかかる処理を示す梯子チャートである。ここでは、管理サーバＳＶとセンサボックスＳＢ－１、ＳＢ－２とのデータのやりとりを示しており、センサボックスＳＢ－２で障害が生じた例を示している。センサボックスＳＢ－２は、センサボックスＳＢ－１と同機種であるから、図３に示すものと同様な構成を有する。尚、その他のセンサボックスとも同様なデータのやりとりが行われる。 FIG. 6 is a ladder chart showing processing according to another embodiment. Here, data exchange between the management server SV and the sensor boxes SB-1 and SB-2 is shown, and an example in which a failure occurs in the sensor box SB-2 is shown. Since the sensor box SB-2 is the same model as the sensor box SB-1, it has the same configuration as that shown in FIG. Similar data is exchanged with other sensor boxes.
　まず図６のステップＳ２０１において、管理サーバＳＶは、データベースＤＢからセンサボックスＳＢ－１、ＳＢ－２用の最新である復旧データセットをそれぞれ読み出す。規定のタイミングで繰り返し、かかる復旧データセットは管理サーバＳＶからセンサボックスＳＢ－１、ＳＢ－２にそれぞれダウンロードされる（ｃ２１、ｃ２２）。センサボックスＳＢ－１の制御部ＣＰＵは、ステップＳ２０２で、ダウンロードした復旧データセットをメモリＭＲに記憶すると共に、管理サーバＳＶに確認信号を送信する。これを受信した管理サーバＳＶは、センサボックスＳＢ－１が正常であることが確認できる。 First, in step S201 in FIG. 6, the management server SV reads the latest restoration data sets for the sensor boxes SB-1 and SB-2 from the database DB. The restoration data set is repeatedly downloaded at a specified timing from the management server SV to the sensor boxes SB-1 and SB-2 (c21 and c22). In step S202, the control unit CPU of the sensor box SB-1 stores the downloaded recovery data set in the memory MR and transmits a confirmation signal to the management server SV. The management server SV that has received this can confirm that the sensor box SB-1 is normal.
　一方、センサボックスＳＢ－２が正常である場合、その制御部ＣＰＵは、ダウンロードした復旧データセットをメモリＭＲに記憶すると共に、管理サーバＳＶに確認信号を送信する。これを受信した管理サーバＳＶは、センサボックスＳＢ－２が正常であることが確認できる。ところが、センサボックスＳＢ－２に障害が生じると、復旧データセットのダウンロードや確認信号の送信を行えなくなる。 On the other hand, when the sensor box SB-2 is normal, the control unit CPU stores the downloaded recovery data set in the memory MR and transmits a confirmation signal to the management server SV. The management server SV receiving this can confirm that the sensor box SB-2 is normal. However, when a failure occurs in the sensor box SB-2, it is impossible to download the recovery data set or transmit a confirmation signal.
　より具体的に説明すると、センサボックスＳＢ－２の制御部ＣＰＵは、上述した実施形態と同様に、規定のタイミングで繰り返し自己診断プログラムに従い自身に障害が発生しているか否か診断する。その結果、障害が生じていると判断した場合、管理サーバＳＶに障害が生じた旨の通知を送信するよう試みる（図４のｃ１２）が、通信機能が損なわれていると管理サーバＳＶに通知が届かない（図４のステップＳ１１１の判定Ｙｅｓ）。更に、センサボックスＳＢ－２のメモリＭＲに復旧データセットが記憶されていない、もしくは読み出せない状態にあると、自律復旧が困難となる。 More specifically, similarly to the above-described embodiment, the control unit CPU of the sensor box SB-2 repeatedly diagnoses whether or not a failure has occurred in accordance with the self-diagnosis program at a specified timing. As a result, when it is determined that a failure has occurred, the management server SV tries to send a notification that a failure has occurred (c12 in FIG. 4), but notifies the management server SV that the communication function is impaired. Has not arrived (determination Yes in step S111 in FIG. 4). Furthermore, if the recovery data set is not stored in the memory MR of the sensor box SB-2 or cannot be read out, autonomous recovery becomes difficult.
　このような場合、センサボックスＳＢ－２から管理サーバＳＶに確認信号も通知も送信されないこととなるので、管理サーバＳＶはセンサボックスＳＢ－２に何らかの障害が生じたと判断できる（すなわち管理サーバＳＶはセンサボックスＳＢ－２に障害が生じたと診断する）。そこで、ステップＳ２０３で、所定時間たっても管理サーバＳＶがセンサボックスＳＢ－２から確認信号を受信しなかったときは、センサボックスＳＢ－２が、管理サーバＳＶとの通信が不能となる無通信状態になっていると判定し、同機種であるセンサボックスＳＢ－１に救援信号を送信する（ｃ２４）。 In such a case, since neither a confirmation signal nor a notification is transmitted from the sensor box SB-2 to the management server SV, the management server SV can determine that some failure has occurred in the sensor box SB-2 (that is, the management server SV Diagnose that a failure has occurred in the sensor box SB-2). Therefore, in step S203, if the management server SV does not receive a confirmation signal from the sensor box SB-2 even after a predetermined time, the sensor box SB-2 cannot communicate with the management server SV. And a rescue signal is transmitted to the sensor box SB-1 of the same model (c24).
　管理サーバＳＶから救援信号を送信されたセンサボックスＳＢ－１の制御部ＣＰＵは、ステップＳ２０４で、メモリＭＲから最新の復旧データセットを読み出して、救助パックとしてセンサボックスＳＢ－２に送信する。これは、図４のステップＳ１１２における外部からの復旧処理の一例に相当する。センサボックスＳＢ－１、ＳＢ－２間で通信が不能である場合、ユーザーの手でセンサボックスＳＢ－１のメモリＭＲから救助パックを読み出して、センサボックスＳＢ－２のメモリＭＲに入力しても良い。或いは、メモリＭＲが取り外し可能なメモリカード等であれば、センサボックスＳＢ－１から抜き出して、センサボックスＳＢ－２のものと差し替えてもよい。 The control unit CPU of the sensor box SB-1 to which the rescue signal is transmitted from the management server SV reads the latest recovery data set from the memory MR and transmits it to the sensor box SB-2 as a rescue pack in step S204. This corresponds to an example of an external recovery process in step S112 in FIG. When communication between the sensor boxes SB-1 and SB-2 is impossible, the rescue pack is read from the memory MR of the sensor box SB-1 by the user's hand and input to the memory MR of the sensor box SB-2. good. Alternatively, if the memory MR is a removable memory card or the like, it may be removed from the sensor box SB-1 and replaced with the sensor box SB-2.
　その救助パックを取得できたとき、センサボックスＳＢ－２の制御部ＣＰＵは、ステップＳ２０５で救助パックから最新の復旧データセットを読み出して、そのパターンテーブルに基づいて、図５のフローに従ってセンサボックスＳＢ－２の障害からの復旧処理を試みる。このとき、復旧データセットのパターンテーブルが図２に示すものであるとき、スプリクトを適用する優先順位としては、括弧内に示すセンサボックスＳＢ－１，ＳＢ－２に共通である成功率が高いスプリクトの順に使用する。センサボックスＳＢ－１，ＳＢ－２は同機種であるものの、ファームウェアのバージョンが異なる場合など、復旧からの成功率がセンサボックスＳＢ－１とセンサボックスＳＢ－２とで異なる可能性がある。従って、センサボックスＳＢ－１単独の成功率が高い順にスプリクトを実行するよりも、共通の成功率が高い順にスプリクトを実行する方が、復旧が早まると推測されるからである。 When the rescue pack can be obtained, the control unit CPU of the sensor box SB-2 reads the latest recovery data set from the rescue pack in step S205, and based on the pattern table, the sensor box SB according to the flow of FIG. -2 Try to recover from the failure. At this time, when the pattern table of the recovery data set is as shown in FIG. 2, the priority for applying the script is a script having a high success rate common to the sensor boxes SB-1 and SB-2 shown in parentheses. Use in the order. Although the sensor boxes SB-1 and SB-2 are of the same model, there is a possibility that the success rate from the recovery is different between the sensor box SB-1 and the sensor box SB-2, for example, when the firmware versions are different. Therefore, it is presumed that recovery is accelerated by executing the scripts in the order of the high common success rate, rather than executing the scripts in the order of the high success rate of the sensor box SB-1.
　その後、センサボックスＳＢ－２の制御部ＣＰＵは，ステップＳ２０６で自己診断プログラムに基づいて障害から復旧したか否かを判断する。但し、センサボックスＳＢ－１の制御部ＣＰＵが、センサボックスＳＢ－２にアクセスした上で，自身の自己診断プログラムを用いてネットワークを介してセンサボックスＳＢ－２の障害の有無を判定しても良い。まだ障害から復旧していないと判断された場合、更にステップＳ２０８で、センサボックスＳＢ－２の制御部ＣＰＵは，パターンテーブルに示されたスプリクト全てを試みたか否か判断する。全てを試みていないと判断した制御部ＣＰＵは、ステップＳ２０５へとフローを戻し、次の優先順位のスプリクトを、救助パックにおける復旧データセットの復旧スプリクト群から選定し、これに従って次の復旧処理を行う。その後、再びステップＳ２０６で、制御部ＣＰＵは障害から復旧したか否かを判断する。 Thereafter, the control unit CPU of the sensor box SB-2 determines whether or not the failure has been recovered based on the self-diagnosis program in step S206. However, even if the control unit CPU of the sensor box SB-1 accesses the sensor box SB-2 and determines whether there is a failure in the sensor box SB-2 via the network using its own self-diagnosis program. good. If it is determined that the failure has not been recovered, the control unit CPU of the sensor box SB-2 further determines whether or not all the scripts shown in the pattern table have been tried in step S208. The control unit CPU, which has determined that all have not been attempted, returns the flow to step S205, selects the next priority script from the recovery script group of the recovery data set in the rescue pack, and performs the next recovery process accordingly. Do. Thereafter, in step S206 again, the control unit CPU determines whether or not the failure has been recovered.
　ステップＳ２０８で、全てのスクリプトに従って復旧処理を試みたにもかかわらず、復旧が行われなかったと判断されると（判定Ｙｅｓ）、救助パックによる復旧が困難となることを意味するので、制御部ＣＰＵは，ステップＳ２０９で、例えばサービスマンの作業など外部処理による復旧を待つこととなる。これに対し、いずれかのスクリプトにて復旧に成功した場合、制御部ＣＰＵはステップＳ２０７で、レポートログを作成する。 If it is determined in step S208 that recovery processing has been attempted in accordance with all the scripts but recovery has not been performed (determination Yes), it means that recovery using the rescue pack becomes difficult, so the control unit CPU In step S209, for example, recovery by an external process such as a serviceman's work is awaited. On the other hand, if the recovery is successful with any script, the control unit CPU creates a report log in step S207.
　その後、センサボックスＳＢ－２の制御部ＣＰＵは、管理サーバＳＶに，作成したレポートログをアップロードする（ｃ２６）。管理サーバＳＶは、ステップＳ２１０で、入力したレポートログに基づいてデータベースＤＢを更新する。これにより、センサボックスＳＢ－２用の復旧データセット、及びセンサボックスＳＢ－１用の復旧データセットの内容（パターンテーブルの括弧内に示す共通の成功率）が書き換えられて、再び管理サーバＳＶからセンサボックスＳＢ－１、ＳＢ－２にそれぞれダウンロードされる（ｃ２１、ｃ２２）。 Thereafter, the control unit CPU of the sensor box SB-2 uploads the created report log to the management server SV (c26). In step S210, the management server SV updates the database DB based on the input report log. As a result, the contents of the recovery data set for the sensor box SB-2 and the recovery data set for the sensor box SB-1 (common success rate shown in parentheses in the pattern table) are rewritten, and again from the management server SV Downloaded to the sensor boxes SB-1 and SB-2, respectively (c21, c22).
