Abstract

Provided is a monitoring system to reduce the burden on caregivers or the like, wherein, even if notifications to caregivers or the like are halted under certain conditions, the monitoring system is capable of minimizing confusion when the notifications are resumed. When the monitoring system transmits event information on a person being monitored from a sensor device to a management server, the management server is configured to record the received event information and transmit the event information to a mobile terminal. When a total temporary stop signal is transmitted from a fixed terminal device to the management server, the management server executes a total temporary stop process in which the event information received from the sensor device is recorded, but the event information is not transmitted to the mobile terminal.

Description

見守りシステムWatch system
　本発明は、介護施設等で好適に用いられる見守りシステムに関する。 The present invention relates to a watching system suitably used in a nursing facility or the like.
　我が国においては、国民の平均寿命の伸びや出生率の低下により少子高齢化が急速に進んでいる。これに伴い、介護が必要な者（要介護者）を収容する病院や老人福祉施設等は増大しつつあるが、過酷な勤務状況などの理由で看護師や介護士の人手が慢性的に足りないという深刻な事態を招いている。特に夜間などにおいては、少ない人数で多くの要介護者を見守らなくてはならず、介護士等の負担が大きくなり、これが更なる人手不足を招く一因となっている。 In Japan, the aging population is declining rapidly due to an increase in the average life expectancy of the people and a decline in the birth rate. Along with this, hospitals and welfare facilities for the elderly that accommodate those who need care (care recipients) are increasing, but the labor of nurses and caregivers is chronically sufficient due to harsh working conditions. This is a serious situation. Especially at night and so on, a small number of people need to watch over a large number of care recipients, which increases the burden on the caregiver and the like, which causes further labor shortages.
　このような介護士等の負担を軽減するため、介護業務を支援する技術が求められている。一例を挙げると、介護士等の仕事の一部を機械に行わせるために、要介護者を監視（モニタ）する種々の技術が開発されている。 In order to reduce the burden on such caregivers, there is a need for technology that supports care work. For example, in order to cause a machine to perform a part of work such as a caregiver, various techniques for monitoring a person who needs care have been developed.
　特許文献１には、カメラにより要介護者を撮像し、その撮像画像に基づいて、制御部が要介護者に危険の迫る予兆があるか否かを判断し、危険の迫る予兆があると判断したときは、例えば電子メールにより、予め定められた介護士等のユーザ端末に通知を行うことができる監視システムが開示されている。特許文献１の監視システムを用いれば、要介護者を監視対象とすることで、その無人監視が可能になり、介護士等の負担が減ることになる。 In Patent Document 1, a person who needs care is imaged by a camera, and based on the captured image, the control unit determines whether or not there is a sign of danger to the care recipient, and judges that there is a sign of danger. In such a case, a monitoring system is disclosed that can notify a user terminal such as a caregiver determined in advance by e-mail. If the monitoring system of patent document 1 is used, it will be possible to perform unattended monitoring by setting a care recipient to be monitored, and the burden on a caregiver or the like will be reduced.

　ところで、介護施設内での定期的な行事（健康体操、避難訓練等）などのため、居室内の要介護者が一斉に部屋を出て移動を開始することがある。又、実際に天災等が生じた場合、全居室の要介護者に退避を要請する場合もある。このような場合に、従来技術の監視システムによれば、居室内から出ようとする要介護者の画像から、危険が迫る予兆があると制御部が判断したときは一斉に電子メールを送信してしまい、受信した大量の電子メールに対応すべく介護士等の負担が却って増大するという問題がある。一方で、制御部の処理を完全に停止してしまうと、居室内で要介護者がとった行動を後から追跡できないという問題がある。 By the way, due to regular events in the care facility (health exercises, evacuation drills, etc.), care recipients in the living room may leave the room and start moving all at once. In addition, when a natural disaster or the like actually occurs, there is a case where the care recipients in all living rooms are requested to evacuate. In such a case, according to the monitoring system of the prior art, when the control unit determines that there is a sign of danger coming from the image of the care recipient who is about to leave the room, an e-mail is sent all at once. Therefore, there is a problem that the burden on the caregiver or the like increases in response to the large amount of received e-mails. On the other hand, if the processing of the control unit is completely stopped, there is a problem that the action taken by the care recipient in the room cannot be traced later.
　本発明は、上記事情に鑑みなされたものであり、介護士等の負担を減らすべく、所定の条件下で介護士等への通知を停止した場合にも、再開時の混乱を抑制できる見守りシステムを提供することを目的とする。 The present invention has been made in view of the above circumstances, and in order to reduce the burden on a caregiver or the like, even when the notification to the caregiver or the like is stopped under a predetermined condition, the watching system can suppress confusion at the time of resumption The purpose is to provide.
　上述した目的のうち少なくとも一つを実現するために、本発明の一側面を反映した見守りシステムは、
　見守り対象者の状態を検出して、それに応じたイベント情報を出力するセンサ装置と、　ネットワークを介して前記センサ装置と通信可能に接続された管理サーバと、
　前記ネットワークを介して前記管理サーバと通信可能に接続された携帯端末と、
　前記ネットワークを介して前記管理サーバと通信可能に接続された固定端末装置と、を有する見守りシステムであって、
　前記センサ装置から見守り対象者のイベント情報を前記管理サーバに送信した場合、前記管理サーバは、受信した前記イベント情報を記録すると共に、前記イベント情報に応じて前記携帯端末に通報信号を送信するようになっており、
　前記固定端末装置から前記管理サーバへと全体一時停止信号が送信された場合、前記管理サーバは、前記センサ装置から受信した前記イベント情報を記録するが、前記携帯端末に前記通報信号を送信しない全体一時停止処理を実行するものである。 In order to achieve at least one of the above-described objects, a monitoring system reflecting one aspect of the present invention is provided.

When the event information of the person being watched over is transmitted from the sensor device to the management server, the management server records the received event information and transmits a notification signal to the mobile terminal according to the event information. And
When the entire temporary stop signal is transmitted from the fixed terminal device to the management server, the management server records the event information received from the sensor device, but does not transmit the notification signal to the portable terminal.

　ＴＡ制御処理部３１は、情報を処理するための回路である。ＴＡ制御処理部３１は、ＳＢ制御処理部１４と同様に、例えば、ＣＰＵおよびその周辺回路を備えて構成される。ＴＡ制御処理部３１は、制御処理プログラムが実行されることによって、ＴＡ制御部３１１およびＴＡ処理部３１２を機能的に備え、ＴＡ処理部３１２は、表示処理部３１２１を機能的に備える。 The TA control processing unit 31 is a circuit for processing information. Similar to the SB control processing unit 14, the TA control processing unit 31 includes, for example, a CPU and its peripheral circuits. The TA control processing unit 31 functionally includes a TA control unit 311 and a TA processing unit 312 by executing a control processing program, and the TA processing unit 312 functionally includes a display processing unit 3121.
　ＴＡ制御部３１１は、携帯端末ＴＡの全体制御を司るものである。 The TA control unit 311 is responsible for overall control of the mobile terminal TA.
　表示処理部３１２１は、ＴＡ表示部３６の表示に関する動作を処理するものである。より具体的には、表示処理部３１２１は、必要に応じてＴＡ表示部３６に動画を表示する。 The display processing unit 3121 processes an operation related to the display of the TA display unit 36. More specifically, the display processing unit 3121 displays a moving image on the TA display unit 36 as necessary.
　このような携帯端末ＴＡは、例えば、いわゆるタブレット型コンピュータやスマートフォンや携帯電話機等の、持ち運び可能な通信端末装置によって構成可能である。 Such a portable terminal TA can be constituted by a portable communication terminal device such as a so-called tablet computer, a smartphone, or a mobile phone.
　次に、実施形態における見守りシステムの動作について説明する。図６は、本実施形態の見守りシステムにおける動作を示す梯子チャート図である。図７は、本実施形態の携帯端末の表示画面の例を示す図である。図８は、管理サーバＳＶのデータベースに記録されるログ情報の例である。 Next, the operation of the watching system in the embodiment will be described. FIG. 6 is a ladder chart showing an operation in the watching system of the present embodiment. FIG. 7 is a diagram illustrating an example of a display screen of the mobile terminal according to the present embodiment. FIG. 8 is an example of log information recorded in the database of the management server SV.
　このような構成の見守りシステムＭＳでは、起動されると、センサボックスＳＢでは、その制御処理プログラムの実行によって、ＳＢ制御処理部１４には、ＳＢ制御部１４１、行動検知処理部１４２，通知処理部１４３、ストリーミング処理部１４４およびナースコール処理部１４５が機能的に構成され、管理サーバＳＶでは、その制御処理プログラムの実行によって、ＳＶ制御処理部２１には、ＳＶ制御部２１１が機能的に構成され、そして、携帯端末ＴＡでは、その制御処理プログラムの実行によって、ＴＡ制御処理部３１には、ＴＡ制御部３１１、表示処理部３１２１を機能的に備えるＴＡ処理部３１２が機能的に構成される。 When the monitoring system MS having such a configuration is activated, in the sensor box SB, the SB control processing unit 14 includes the SB control unit 141, the behavior detection processing unit 142, and the notification processing unit by executing the control processing program. 143, the streaming processing unit 144 and the nurse call processing unit 145 are functionally configured. In the management server SV, the SV control processing unit 211 is functionally configured by executing the control processing program. In the portable terminal TA, a TA processing unit 312 functionally including a TA control unit 311 and a display processing unit 3121 is functionally configured in the TA control processing unit 31 by executing the control processing program.
　見守りシステムＭＳの動作について説明するが、ナースコールイベントについては省略する。携帯端末ＴＡでは、例えば介護士等のログイン操作(詳細は後述)を受け付けると、携帯端末ＴＡは、ＴＡ処理部３１２によって、自機宛の通信信号を待ち受ける待受け画面をＴＡ表示部（モニタ）３６に表示する。この待受け画面は、例えば、図７（ａ）に示すように、メニューバーを表示するメニューバー領域６１１と、待ち受け中であることを表すメッセージ（例えば「未対応通知はありません」）、日付や現在時刻、当該携帯端末ＴＡにログインしているユーザ名（介護士）などを表示する待受けメイン領域６１２とを備える。このような待受け画面を表示すると、携帯端末ＴＡは、ＴＡ制御部３１１によって、ＴＡ通信ＩＦ部３３で通信信号の受信を待つ。 The operation of the watch system MS will be described, but the nurse call event will be omitted. When the portable terminal TA receives a login operation (details will be described later) of a caregiver or the like, for example, the portable terminal TA displays a standby screen for waiting for a communication signal addressed to itself by the TA processing unit 312. To display. For example, as shown in FIG. 7A, the standby screen includes a menu bar area 611 for displaying a menu bar, a message indicating that the standby is in progress (for example, “no unsupported notification”), date and current A standby main area 612 for displaying a time, a user name (caregiver) who logs in the portable terminal TA, and the like. When such a standby screen is displayed, the portable terminal TA waits for the TA communication IF unit 33 to receive a communication signal by the TA control unit 311.
　ここで通常時には、全体一時停止指示は解除されているものとする。センサボックスＳＢは、図６のステップＳ１０１において、ＳＢ制御部１４１によって、所定のフレームレートに応じたサンプリング周期でセンサ部１１のドップラセンサ１１１の出力データをサンプリングするとともにカメラ１１２で画像データを取得し、不図示のリングバッファに記憶しつつ、行動検知処理部１４２によって、このサンプリングおよび取得したドップラセンサ１１１の出力データおよびカメラ１１２の画像データを解析する。この解析の結果、ステップＳ１０２で、ＳＢ制御部１４１が所定のイベント（起床、離床、転倒、転落および微体動異常）を検出しない場合には、フローをステップＳ１０１へと戻して検知動作を続行する。一方、ＳＢ制御部１４１が所定のイベントを検出したときは、ステップＳ１０３で、イベント前後の画像データ及び／又は微体動データを、リングバッファから切り出してＳＢ記憶部１６に記憶する。 Here, it is assumed that the general suspension instruction is canceled at normal times. In step S101 of FIG. 6, the sensor box SB samples output data of the Doppler sensor 111 of the sensor unit 11 at a sampling period corresponding to a predetermined frame rate by the SB control unit 141 and acquires image data by the camera 112. The behavior detection processing unit 142 analyzes the sampled and acquired output data of the Doppler sensor 111 and the image data of the camera 112 while being stored in a ring buffer (not shown). As a result of this analysis, when the SB control unit 141 does not detect a predetermined event (wake-up, getting-off, falling, falling, falling, or minute body movement abnormality) in step S102, the flow returns to step S101 to continue the detection operation. To do. On the other hand, when the SB control unit 141 detects a predetermined event, the image data and / or minute motion data before and after the event are cut out from the ring buffer and stored in the SB storage unit 16 in step S103.
　更にセンサボックスＳＢは、通知処理部１４３によって、どの種類の通知イベントが発生したかを示すイベント情報と、通信アドレスを含む通知信号を、ネットワークＮＷを介して管理サーバＳＶへ送信する（Ｃ１１）。かかる通知信号は、対象者の画像データを含まないので情報量が少ない。但し、静止画もしくは短時間の動画を、通知信号に添付しても良い。かかる静止画もしくは動画が添付された場合、管理サーバＳＶのデータベースに、ログ情報の一部として記録できる。 Further, the sensor box SB transmits event information indicating which type of notification event has occurred and a notification signal including a communication address to the management server SV via the network NW by the notification processing unit 143 (C11). Since the notification signal does not include the image data of the subject person, the amount of information is small. However, a still image or a short-time movie may be attached to the notification signal. When such a still image or moving image is attached, it can be recorded as a part of log information in the database of the management server SV.
　このような通知信号がセンサボックスＳＢから送信されると、管理サーバＳＶは、ステップＳ１０４で、データベースにログ情報を記録する。図８は、データベース中に記録されたログ情報の一部を示す図である。図８の例では、１３時２４分に居室ＲＭ－１のセンサボックスＳＢから「起床」のイベント情報を送信され、これに応じて介護士ＮＡさんが対応したこと、１４時００分に居室ＲＭ－２のセンサボックスＳＢから「転倒」のイベント情報を送信され、これに応じて介護士ＮＢさんが対応したこと、１４時１２分に居室ＲＭ－３のセンサボックスＳＢから「起床」のイベント情報を送信され、これに応じて介護士ＮＣさんが対応したこと、１４時２３分に居室ＲＭ－４のセンサボックスＳＢから「起床」のイベント情報を送信され、これに応じて介護士ＮＡさんが対応したこと、１４時３９分に居室ＲＭ－１のセンサボックスＳＢから「転倒」のイベント情報を送信され、これに応じて介護士ＮＡさんが対応したことが時系列的に記録される。尚、この時点で、対応者名は未定であるので、対応者名の欄は、後から携帯端末ＴＡからの情報により補充される。 When such a notification signal is transmitted from the sensor box SB, the management server SV records log information in the database in step S104. FIG. 8 is a diagram showing a part of log information recorded in the database. In the example of FIG. 8, “wake-up” event information is transmitted from the sensor box SB of the room RM-1 at 13:24, and the caregiver NA responds accordingly, and the room RM at 14:00. -2 event box information was sent from the sensor box SB, and the caregiver NB responded accordingly, and at 14:12 from the sensor box SB in the room RM-3 "wake-up" event information , And the caregiver NC responded accordingly, the event information of “wake up” was sent from the sensor box SB of the room RM-4 at 14:23, and the caregiver NA responded accordingly. At 14:39, event information “falling” is transmitted from the sensor box SB of the room RM-1, and in response to this, it is recorded in time series that the caregiver NA has responded. At this point, since the name of the correspondent is not yet determined, the corresponding name column is supplemented later with information from the portable terminal TA.
　図６のステップＳ１０５で、管理サーバＳＶは、固定端末装置ＳＰから全体一時停止指示信号を受信していないか判断する。ここでは、全体一時停止指示信号を受信していないものとして、フローをステップＳ１０６へと進める。 In step S105 in FIG. 6, the management server SV determines whether or not an overall suspension instruction signal has been received from the fixed terminal device SP. Here, assuming that the entire pause instruction signal has not been received, the flow proceeds to step S106.
　ステップＳ１０６で、管理サーバＳＶは、通知信号に含まれている情報を、通知先情報記憶部２２１に記憶されている通知先情報テーブル４１と照合して、送信元の通信アドレスに対応する送信先の通信アドレスから居住者が誰か（例えばＢさん）を判断し、更に、通知信号のイベント情報から、その居住者（Ｂさん）に対応する通知イベントの種類（ここでは転倒又は転落）に該当するかを判断する。そして、受信した通知信号のイベント情報が通知イベントを示している場合には、端末への通知を行うことを決定する。一方、受信した通知信号のイベント情報が通知イベントを示していない場合（Ｂさんの場合、起床又は離床）、端末への通知を行わないことを決定し、次の通知信号を待ち受ける。 In step S106, the management server SV collates the information included in the notification signal with the notification destination information table 41 stored in the notification destination information storage unit 221, and transmits the transmission destination corresponding to the communication address of the transmission source. The person who is a resident (for example, Mr. B) is determined from the communication address of, and the event information of the notification signal corresponds to the type of notification event corresponding to the resident (Mr. B) (here, falls or falls). Determine whether. When the event information of the received notification signal indicates a notification event, it is determined to notify the terminal. On the other hand, when the event information of the received notification signal does not indicate a notification event (in the case of Mr. B, wakes up or leaves), it is determined not to notify the terminal and waits for the next notification signal.
　ステップＳ１０６にて管理サーバＳＶが、端末への通知を決定した場合、通知先情報記憶部２２１に記憶されている通知先情報テーブル４１と照合して、送信元の通信アドレスに対応する送信先の通信アドレスから、送信先の携帯端末ＴＡを選定する。より具体的には、通知先情報記憶部２２１に記憶されている通知先情報テーブル４１において、通知元アドレスフィールド４１１に、前記受信した通知信号の送信元の通信アドレスを登録しているレコードにおける通知先アドレスフィールド４１３に登録されている通知先の通信アドレスを取り出す。例えば、ＲＭ－２号室に配設された通信アドレス「１９２．１６８．１０．１２１」を持つセンサボックスＳＢ－２からの通知信号を受信した場合には、この通知信号の送信元の通信アドレス「１９２．１６８．１０．１２１」を登録している２行目のレコードにおける通知先アドレスフィールド４１３に登録されている通知先の３個の通信アドレス「１９２．１６８．１０．２５」、「１９２．１６８．１０．２６」、「１９２．１６８．１０．２７」が取り出される。なお、この例では、通信アドレス「１９２．１６８．１０．２５」は、介護士ＮＡさんが持つ携帯端末ＴＡ－１に付与された通信アドレスであり、通信アドレス「１９２．１６８．１０．２６」は、介護士ＮＢさんが持つ携帯端末ＴＡ－２に付与された通信アドレスであり、そして、通信アドレス「１９２．１６８．１０．２７」は、図略の介護士ＮＣさんが持つ携帯端末ＴＡ－３に付与された通信アドレスである。 When the management server SV determines notification to the terminal in step S106, the management server SV compares the notification destination information table 41 stored in the notification destination information storage unit 221 with the destination address corresponding to the source communication address. The destination mobile terminal TA is selected from the communication address. More specifically, in the notification destination information table 41 stored in the notification destination information storage unit 221, the notification in the record in which the communication address of the transmission source of the received notification signal is registered in the notification source address field 411. The communication address of the notification destination registered in the destination address field 413 is extracted. For example, when a notification signal is received from the sensor box SB-2 having the communication address “192.168.10.121” disposed in the RM-2 room, the communication address “ Three communication addresses “192.168.10.25” and “192.192.1” registered in the notification destination address field 413 in the record in the second row in which “192.168.10.121” is registered. 168.10.26 "and" 192.168.10.27 "are retrieved. In this example, the communication address “192.168.10.25” is a communication address assigned to the portable terminal TA-1 owned by the caregiver NA, and the communication address “192.168.10.26”. Is the communication address assigned to the mobile terminal TA-2 owned by the caregiver NB, and the communication address "192.168.10.27" is the mobile terminal TA- 3 is a communication address assigned to the network.
　そして、管理サーバＳＶは、ＲＭ－２号室で転倒又は転落が生じた情報を含む通報信号を、選定した携帯端末ＴＡ－１～ＴＡ－３及び固定端末ＳＰへ送信する（Ｃ１２）。 Then, the management server SV transmits a notification signal including information that the fall or the fall has occurred in the RM-2 room to the selected portable terminals TA-1 to TA-3 and the fixed terminal SP (C12).
　このような通報信号が管理サーバＳＶから送信されると、携帯端末ＴＡは、ＴＡ処理部３１２によってＴＡ表示部３６の画面表示を、例えば図７（ｂ）に示すものに切り替える。このとき、提示部としてのＴＡ音入出力部３４を介して、音や音声などの出力（例えば「ＲＭ－２号室で転落発生」などの音声メッセージ）を行ったり、或いは振動等により介護士に通報信号の受信を知らせても良い。 When such a notification signal is transmitted from the management server SV, the portable terminal TA switches the screen display of the TA display unit 36 to the one shown in FIG. At this time, the TA sound input / output unit 34 serving as a presentation unit is used to output sounds and voices (for example, a voice message such as “falling in RM-2”) or to the caregiver by vibration or the like. The reception of the notification signal may be notified.
　図７（ｂ）に示す例では、メイン領域６１２に、イベントが生じた居室名（ＲＭ－２号室、すなわち通知を送信したセンサボックスに関する情報）と，当該居室の居住者の氏名（Ｂ様）と、転倒又は転落を示すアイコンＩＣ１と、通知時間と現在との時間差（０分）が表示される（ステップＳ１０７）。同時に、メイン領域６１２に、ボタンＢ１（対応する），Ｂ２（話す），Ｂ３（記憶映像を見る）、Ｂ４（ライブ映像を見る）が表示される。 In the example shown in FIG. 7B, in the main area 612, the name of the room where the event occurred (RM-2, that is, information on the sensor box that sent the notification) and the name of the resident in the room (B) Then, an icon IC1 indicating a fall or a fall and a time difference (0 minutes) between the notification time and the current time are displayed (step S107). At the same time, buttons B1 (corresponding), B2 (speak), B3 (view stored video), and B4 (view live video) are displayed in the main area 612.
　ここで、介護士がボタンＢ３又はＢ４にタッチすると、携帯端末ＴＡのＴＡ入力部３５が反応し、ステップＳ１０８で、ＴＡ制御部３１１が画像のリクエストがなされたと判断して、ＴＡ通信ＩＦ部からネットワークＮＷを介して管理サーバＳＶにリクエスト信号（状態データリクエスト信号）が送信される（Ｃ１３）。ここでリクエスト信号には、要求種別（記憶映像又はライブ映像）が含まれる。管理サーバＳＶは、リクエスト信号を中継して対象となるセンサボックスＳＢに送信する。尚、リクエスト信号は、直接センサボックスＳＢに送信されても良い。 Here, when the caregiver touches the button B3 or B4, the TA input unit 35 of the portable terminal TA reacts, and in step S108, the TA control unit 311 determines that an image request has been made, and the TA communication IF unit A request signal (status data request signal) is transmitted to the management server SV via the network NW (C13). Here, the request signal includes a request type (stored video or live video). The management server SV relays the request signal and transmits it to the target sensor box SB. The request signal may be transmitted directly to the sensor box SB.
　リクエスト信号を受信したセンサボックスＳＢは、ステップＳ１０９で、リクエスト信号中の要求種別を判別する。介護士がボタンＢ３をタッチした場合、携帯端末ＴＡから、記憶画像を要求するリクエスト信号が出力されるので、管理サーバＳＶを介してこれを受信したセンサボックスＳＢが記憶映像を要求されていると判断して、ステップＳ１１１でＳＢ記憶部１６から画像データを読み出して、ＳＢ通信ＩＦ部１５からネットワークＮＷを介して管理サーバＳＶに送信する（Ｃ１４）。或いは、介護士がボタンＢ４をタッチした場合、携帯端末ＴＡから、ライブ映像を要求するリクエスト信号が出力されるので、管理サーバＳＶを介してこれを受信したセンサボックスＳＢがライブ映像を要求されていると判断して、ステップＳ１１０でカメラ１１０で撮像してなるライブ映像をエンコードして、ＳＢ通信ＩＦ部１５からネットワークＮＷを介して管理サーバＳＶに送信する（Ｃ１４）。ライブ映像はリングバッファから切り出されても良い。管理サーバＳＶは、画像データを中継してリクエスト信号を送信した携帯端末ＴＡに送信する。尚、画像データは、直接携帯端末ＴＡに送信されても良い。 The sensor box SB that has received the request signal determines the request type in the request signal in step S109. When the caregiver touches the button B3, a request signal for requesting a stored image is output from the portable terminal TA. Therefore, the sensor box SB that has received the request via the management server SV requests a stored image. In step S111, image data is read from the SB storage unit 16 and transmitted from the SB communication IF unit 15 to the management server SV via the network NW (C14). Alternatively, when the caregiver touches the button B4, a request signal for requesting a live image is output from the portable terminal TA, and the sensor box SB that has received the request via the management server SV is requested for the live image. In step S110, the live video imaged by the camera 110 is encoded and transmitted from the SB communication IF unit 15 to the management server SV via the network NW (C14). The live video may be cut out from the ring buffer. The management server SV transmits the image data to the portable terminal TA that has transmitted the request signal. Note that the image data may be transmitted directly to the portable terminal TA.
　画像データを受信した携帯端末ＴＡは、ＴＡ処理部３１２によってＴＡ表示部３６の画面表示を、例えば図７（ｃ）に示すものに切り替える。記憶映像を要求した図７（ｃ）に示す例では、メイン領域６１２に、ＲＭ－２号室で転倒した前後のＢさんの画像（映像）ＩＭＧが表示されるので(ステップＳ１１２)、かかる画像ＩＭＧを見た介護士は、すぐに対応すべき状態か否かを判断することができる。又、画像ＩＭＧを見ただけでは判断できない場合、介護士がボタンＢ２をタッチすることで、センサボックスＳＢのＳＢ音入出力部１２を介して、Ｂさんと介護士とが直接会話できるため、状況を正確に判断することができる。又、ライブ映像を要求した場合、携帯端末ＴＡに表示される画像は、現在のストリーミング画像である。上記の例では、携帯端末ＴＡに通報信号を送信するようにしているが、及び／又は固定端末ＳＰに通報信号を送信するようにしても良い。尚、画像のリクエストは、通報信号にかかわらず任意で行うことができる。 The mobile terminal TA that has received the image data switches the screen display of the TA display unit 36 to the one shown in FIG. In the example shown in FIG. 7C in which the stored video is requested, since the image (video) IMG of Mr. B before and after falling down in the RM-2 room is displayed in the main area 612 (step S112), the image IMG The caregiver who sees can immediately determine whether or not the state should be dealt with. In addition, if it cannot be determined by just looking at the image IMG, the caregiver can touch the button B2 so that Mr. B and the caregiver can directly talk via the SB sound input / output unit 12 of the sensor box SB. The situation can be judged accurately. When a live video is requested, the image displayed on the portable terminal TA is the current streaming image. In the above example, the notification signal is transmitted to the portable terminal TA, and / or the notification signal may be transmitted to the fixed terminal SP. The image request can be arbitrarily made regardless of the notification signal.
　尚、ステップＳ１０７で表示されたアイコンＩＣ１を見た介護士が、イベントが生じたＲＭ－２号室に駆けつけて対応を行った後、ボタンＢ１をタッチすることで、管理サーバＳＶに、介護士が対応した旨の情報が送信されることとなる。かかる情報を受信した管理サーバＳＶは、情報の発信元の携帯端末から、そのイベント情報に対応した介護士名を特定して、データベースのログ情報（図８）に対応者として記録することができる。操作された携帯端末ＴＡは、待ち受け画面（図７（ａ））に戻る。 The caregiver who sees the icon IC1 displayed in step S107 rushes to room RM-2 where the event has occurred and responds, and then touches the button B1 so that the caregiver can access the management server SV. Information to the effect is transmitted. The management server SV that has received such information can identify the name of the caregiver corresponding to the event information from the portable terminal that is the source of the information, and record it as the corresponding person in the log information of the database (FIG. 8). . The operated mobile terminal TA returns to the standby screen (FIG. 7A).
　図９は、携帯端末の別な表示画面例を示す図である。以上述べた例では、センサボックスＳＢが，取得した画像データから対象者が転倒又は転落したと判断して、管理サーバＳＶに通知信号を送信しているが、例えば微体動の異常を検出して、管理サーバＳＶに通知信号を送信することもできる。かかる場合、上述した例と同様に、管理サーバＳＶから選定した携帯端末ＴＡへ、微体動異常であることを示す通報信号を送信し、受信した携帯端末ＴＡにて、微体動異常であることを示すアイコンＩＣ２を表示するようにしても良い。この場合、介護士がボタンＢ３をタッチすることで、居室内の画像転送（或いは微体動データの転送）をリクエストすることが出来、また介護士がボタンＢ２をタッチすることで、センサボックスＳＢのＳＢ音入出力部１２を介して、対象者と介護士とが直接会話できるため、状況を正確に判断することができる。カメラで撮像した画像の解析と、ドップラセンサにより検知した微体動の状態とを総合して、イベント判断に用いても良い。 FIG. 9 is a diagram showing another display screen example of the mobile terminal. In the example described above, the sensor box SB determines that the subject has fallen or falls from the acquired image data and transmits a notification signal to the management server SV. Thus, a notification signal can be transmitted to the management server SV. In this case, as in the above-described example, the notification signal indicating that the micromotion is abnormal is transmitted from the management server SV to the selected mobile terminal TA, and the micromotion is abnormal in the received mobile terminal TA. An icon IC2 indicating this may be displayed. In this case, the caregiver can touch the button B3 to request image transfer (or transfer of minute motion data) in the room, and the caregiver can touch the button B2 to touch the sensor box SB. Since the subject and the caregiver can directly talk via the SB sound input / output unit 12, the situation can be accurately determined. The analysis of the image captured by the camera and the state of minute movement detected by the Doppler sensor may be combined and used for event determination.
　ところで、介護施設内での定期的な行事などのため、居室内の要介護者が一斉に部屋を出て移動を開始することがある。又、実際に天災等が生じた場合、全居室の要介護者に退避を要請する場合もある。このような場合、センサボックスＳＢが全居室内の居住者の動きを検出して、一斉にイベント情報を送信し始める場合があり、これに応じて各介護士の管理する携帯端末へと通報信号が多数送信される恐れがある。そこで、このような場合、図６のステップＳ１５０に示すように、施設の責任者等が固定端末装置ＳＰを介して「全体一時停止指示」を入力する。 By the way, due to regular events in nursing care facilities, care recipients in the living room may leave the room and start moving. In addition, when a natural disaster or the like actually occurs, there is a case where the care recipients in all living rooms are requested to evacuate. In such a case, the sensor box SB may detect the movements of the residents in all the living rooms and start transmitting event information all at once, and in response to this, a notification signal is sent to the mobile terminal managed by each caregiver. May be sent in large numbers. Therefore, in such a case, as shown in step S150 of FIG. 6, the person in charge of the facility inputs an “overall suspension instruction” via the fixed terminal device SP.
　かかる場合、固定端末装置ＳＰから管理サーバＳＶへ、全体一時停止指示信号が送信される（Ｃ１５）。これを受信した管理サーバＳＶは、ステップＳ１０５で、全体一時停止指示を受けたと判断し、イベント情報の受信にかかわらず、フローをステップＳ１０４へと戻す。つまり、管理サーバＳＶは，いかなるイベント情報を受信しても携帯端末ＴＡに送信しない全体一時停止処理を実行するのである。これにより、介護士が携帯端末から発報される情報に煩わされることがなくなり、自身の作業に専念できる。 In such a case, an entire suspension instruction signal is transmitted from the fixed terminal device SP to the management server SV (C15). Receiving this, the management server SV determines in step S105 that an overall suspension instruction has been received, and returns the flow to step S104 regardless of reception of event information. In other words, the management server SV executes a whole pause process that does not transmit any event information to the portable terminal TA. Thereby, the caregiver is not bothered by the information issued from the portable terminal, and can concentrate on his / her work.
　但し、全体一時停止処理を開始した管理サーバＳＶは、所定の通報信号（全体一時停止処理中であることを示す情報）をログインしている全ての携帯端末ＴＡに対して発信し、かかる通報信号を受信した携帯端末ＴＡは、例えば図１０に示すごとく、全体一時停止処理中であることを示す表示をメイン領域６１２に行っても良い。これにより、携帯端末ＴＡを所持する介護士は、全体一時停止処理中であるため管理サーバからイベント情報に関する通報がこないことを知ることができる。 However, the management server SV that has started the entire suspension process transmits a predetermined notification signal (information indicating that the entire suspension process is being performed) to all the mobile terminals TA that have logged in, and the notification signal For example, as illustrated in FIG. 10, the mobile terminal TA that has received the message may display in the main area 612 that the entire pause process is being performed. Thereby, the caregiver possessing the portable terminal TA can know that there is no report about the event information from the management server because the entire temporary suspension process is being performed.
　但し、全体一時停止処理を実行中でも、管理サーバＳＶは、イベント情報が送信された事実を記録してゆくことが望ましい。例えば図８に示す例で、１５:００に全体一時停止指示が入力されたものとすると、その後の１５時０１分に居室ＲＭ－２のセンサボックスＳＢから「転倒」のイベント情報を送信され、１５時０９分に居室ＲＭ－１のセンサボックスＳＢから「転倒」のイベント情報を送信され、１５時１８分に居室ＲＭ－２のセンサボックスＳＢから「転倒」のイベント情報を送信され、１５時３１分に居室ＲＭ－１のセンサボックスＳＢから「転倒」のイベント情報を送信され、１５時４２分に居室ＲＭ－２のセンサボックスＳＢから「転倒」のイベント情報を送信された場合、管理サーバＳＶは、その旨をデータベースに記録するが、対応する介護士の形態端末に通知を行わず、更にログ情報の対応者名の欄を空欄とする。これにより全体一時停止解除後において、センサボックスＳＢを通じての見守り対象者の行動に矛盾が生じないようにできる。又、全体一時停止処理中に対象者Ｏｂにイベントが生じた場合でも、データベースに記録された情報に基づいて、その原因解析を行うこともできる。 However, it is desirable that the management server SV records the fact that the event information has been transmitted even while the entire suspension process is being executed. For example, in the example shown in FIG. 8, assuming that the entire pause instruction is input at 15:00, event information “falling” is transmitted from the sensor box SB of the room RM-2 at 15:01, At 15:09, event information of “falling” is transmitted from the sensor box SB of the room RM-1, and at 15:18, event information of “falling” is transmitted from the sensor box SB of the room RM-2. If the event information of “falling” is sent from the sensor box SB of the room RM-1 at 31 minutes and the event information of “falling” is sent from the sensor box SB of the room RM-2 at 15:42, the management server The SV records that fact in the database, but does not notify the corresponding caregiver's form terminal, and further leaves the corresponding name column of the log information blank. Thereby, it is possible to prevent contradiction in the behavior of the person being watched over through the sensor box SB after canceling the entire pause. Further, even when an event occurs in the subject Ob during the entire pause process, the cause analysis can be performed based on the information recorded in the database.
　一方、介護施設の行事が終わり、全体一時停止処理が不要となった場合、図６のステップＳ１５０に示すように、施設の責任者が固定端末装置ＳＰを介して「全体一時停止解除指示」を入力する。かかる場合、固定端末装置ＳＰからから管理サーバＳＶへ、全体一時停止解除指示信号が送信される（Ｃ１５）。これを受信した管理サーバＳＶは、ステップＳ１０５で、全体一時停止解除指示を受けたと判断し、全体一時停止処理を解除する。これにより、管理サーバＳＶは、上述したように所定のイベント情報を受信したときは、対応する介護士の形態端末へと通報信号の送信を再開する。更に、管理サーバＳＶは、受信したイベント情報に対応してデータベースにログ情報を記録する。 On the other hand, when the event of the care facility is over and the entire suspension process is no longer necessary, the person in charge of the facility issues an “overall suspension cancellation instruction” via the fixed terminal device SP as shown in step S150 of FIG. input. In such a case, the entire temporary stop cancellation instruction signal is transmitted from the fixed terminal device SP to the management server SV (C15). In step S105, the management server SV that has received this determines that it has received an instruction to cancel the entire pause, and cancels the entire pause process. Thereby, management server SV resumes transmission of a report signal to the corresponding form terminal of a caregiver when predetermined event information is received as described above. Further, the management server SV records log information in the database corresponding to the received event information.
　例えば図８に示す例で、１６:００に全体一時停止解除指示が入力されたものとすると、その後の１６時０３分に居室ＲＭ－１のセンサボックスＳＢから「転倒」のイベント情報を送信され、介護士ＮＡさんが対応したこと、１６時１１分に居室ＲＭ－２のセンサボックスＳＢから「転落」のイベント情報を送信され、介護士ＮＢさんが対応したこと、１６時２３分に居室ＲＭ－３のセンサボックスＳＢから「転倒」のイベント情報を送信され、介護士ＮＣさんが対応したこと、１６時３８分に居室ＲＭ－４のセンサボックスＳＢから「転落」のイベント情報を送信され、介護士ＮＡさんが対応したこと、１６時４７分に居室ＲＭ－１のセンサボックスＳＢから「転倒」のイベント情報を送信され、介護士ＮＡさんが対応したことを、管理サーバＳＶはデータベースに記録する。つまり、管理サーバＳＶは、対応者名の欄が空欄であるか否かで、携帯端末ＴＡに通報信号を送信しなかったイベント情報（１５:００～１６：００）と、通報信号を送信したイベント情報（１５:００以前及び１６：００以降）とを区別して記録することになる。尚、ログ情報には、全体一時停止指示が入力された時刻１５：００、及び全体一時停止解除指示が入力された時刻１６：００（すなわち全体一時停止処理の実行時間に関する情報）が記録されるので、これから全体一時停止処理が実行されていた時間が１時間であることがわかる。 For example, in the example shown in FIG. 8, if an instruction to cancel the entire pause is input at 16:00, event information “falling” is transmitted from the sensor box SB of the room RM-1 at 16:03. , The caregiver NA responded, the event information of “falling” was sent from the sensor box SB of the room RM-2 at 16:11, and the caregiver NB responded, the room RM at 16:23 -3 sensor box SB was sent "falling" event information, the caregiver NC responded, and at 16:38 the room box RM-4 sensor box SB was sent "falling" event information, It was confirmed that the caregiver NA responded and that the event information “falling” was sent from the sensor box SB of the room RM-1 at 16:47, and that the caregiver NA responded. The server SV is recorded in the database. That is, the management server SV transmits the event information (15:00 to 16:00) that did not transmit the notification signal to the mobile terminal TA and the notification signal depending on whether or not the name of the corresponding person is blank. Event information (before 15:00 and after 16:00) is recorded separately. In the log information, the time 15:00 when the entire pause instruction is input and the time 16:00 when the entire pause release instruction is input (that is, information regarding the execution time of the entire pause process) are recorded. Therefore, it can be seen from this that the time during which the entire suspension process has been executed is one hour.
　又、管理サーバＳＶは、例えば施設の責任者が全体一時停止解除指示の入力を失念した場合に備えて、全体一時停止指示が入力された時刻からタイマ(不図示)をスタートさせ、かかるタイマが制限時間(例えば１時間半)を計時した時点で、全体一時停止解除を強制的に行うようにしても良い。又、タイマが制限時間を経過する前（例えば制限時間経過の１０分前）に、管理サーバＳＶから固定端末装置ＳＰにリマインダ信号を送信し、このリマインダ信号を受信した固定端末装置ＳＰが、自身のモニタに、「全体一時停止強制解除の制限時間１０分前です」などの情報（全体一時停止処理を解除することに関する情報）を表示して、施設の責任者に対応を促すようにしても良い。このようなリマインダ信号は、管理サーバＳＶから携帯端末ＴＡに送信されても良い。 Also, the management server SV starts a timer (not shown) from the time when the entire pause instruction is input, for example, when the person in charge of the facility forgets to input the entire pause cancellation instruction. The total suspension may be forcibly canceled when a time limit (for example, one and a half hours) is counted. Also, before the timer expires (for example, 10 minutes before the expiration of the limit time), the management server SV transmits a reminder signal to the fixed terminal device SP, and the fixed terminal device SP that has received this reminder signal itself Display information such as “10 minutes before the time limit for the forced suspension of the entire suspension” on the monitor (information regarding the cancellation of the entire suspension processing) and prompt the person responsible for the facility to respond. good. Such a reminder signal may be transmitted from the management server SV to the portable terminal TA.
　次に、管理サーバＳＶへのログイン処理について説明する。図１１は、携帯端末ＴＡと管理サーバＳＶとの間で行われるログイン処理の梯子チャートであって、図６の制御と並行して行われるものである。ここでは、勤務を開始した介護士の一人（ユーザ名：００１０）が、自分が管理する携帯端末ＴＡのメインスイッチをオン操作したものとする。すると、図１２に示すようなログイン画面が表示される。「Ａｎｄｒｏｉｄ（登録商標）」等のＯＳを使用する携帯端末では、標準のログイン画面が表示されるのであるが、ここでは図１２に示すようなログイン画面を最初に表示するようにカスタマイズされている。 Next, login processing to the management server SV will be described. FIG. 11 is a ladder chart of a login process performed between the portable terminal TA and the management server SV, and is performed in parallel with the control of FIG. Here, it is assumed that one of the caregivers who started working (user name: 0010) has turned on the main switch of the mobile terminal TA managed by the caregiver. Then, a login screen as shown in FIG. 12 is displayed. In a portable terminal using an OS such as “Android (registered trademark)”, a standard login screen is displayed. Here, the login screen as shown in FIG. 12 is customized to be displayed first. .
　図１１のステップＳ２０１で、ユーザによりログイン操作が行われることで、見守りシステム内の一部として、ログインした携帯端末が有効になる。より具体的には，図１２に示すログイン画面にて、ユーザが「ユーザ名」の入力欄ＣＬ１の右端の三角マークＭＫ１をタップすることで、複数の選択肢が表示されるから、そのうち自分のユーザ名「００１０」をタップしてユーザ名（ユーザＩＤ）を選択し、更に「パス」の入力欄ＣＬ２に、その下方に表示された数字キーＮＫを用いて、４桁の数字を入力する。その後ユーザがボタンＢ１１をタップすることで、ログイン操作が完了する。尚、パスの入力は省略しても良い。 In step S201 in FIG. 11, the login operation is performed by the user, so that the logged-in mobile terminal becomes valid as a part of the watching system. More specifically, when the user taps the triangle mark MK1 at the right end of the “user name” input field CL1 on the login screen shown in FIG. 12, a plurality of options are displayed. A name “0010” is tapped to select a user name (user ID), and a four-digit number is input to the “pass” input field CL2 using the numeric keys NK displayed below the input field CL2. Thereafter, the user taps the button B11 to complete the login operation. The path input may be omitted.
　図１２におけるステップＳ２０１のログイン操作により、ユーザに関する情報としてのユーザ名や端末ＩＤ(識別子情報)等を含むログイン要求信号が、携帯端末ＴＡから管理サーバＳＶに送信される（Ｃ２１）。更に、携帯端末ＴＡは、ステップＳ２０２でＴＡ記憶部３２（不揮発性メモリであると好ましい）に、ログインに用いたログイン情報であるユーザ名や端末ＩＤを記憶する。 As a result of the login operation in step S201 in FIG. 12, a login request signal including a user name and terminal ID (identifier information) as information about the user is transmitted from the portable terminal TA to the management server SV (C21). Furthermore, the portable terminal TA stores the user name and terminal ID, which are login information used for login, in the TA storage unit 32 (preferably a non-volatile memory) in step S202.
　携帯端末ＴＡからログイン要求信号を受信した管理サーバＳＶは、ＳＶ記憶部２２に記憶したデータベース内を参照し、ユーザ名とパスが一致するか否かを確認してログイン認証を行い(ステップＳ２０３)、ユーザ名とパスが一致すれば、管理サーバＳＶはログイン処理を実行することができる。 The management server SV that has received the login request signal from the portable terminal TA refers to the database stored in the SV storage unit 22, confirms whether the user name and the path match, and performs login authentication (step S203). If the user name and the path match, the management server SV can execute the login process.
　管理サーバＳＶのログイン認証が完了すると、携帯端末ＴＡと管理サーバＳＶにアクセスできるようになり、また携帯端末ＴＡを宛先とする通報信号を受信することができるようになる。更に、携帯端末ＴＡからの要求に応じて、管理サーバＳＶは必要な情報のダウンロードを許可する（データ授受）。これにより、ユーザ「００１０」は，管理サーバＳＶのデータベースに記録された自身の担当する対象者Ｏｂの情報等を閲覧でき、適切な介護等を行うことができる。又、上述したように、担当する居室のセンサボックスＳＢから，自身が管理する携帯端末ＴＡへと送信されるイベント情報を確認することができる。 When the login authentication of the management server SV is completed, the mobile terminal TA and the management server SV can be accessed, and a notification signal destined for the mobile terminal TA can be received. Furthermore, in response to a request from the portable terminal TA, the management server SV permits downloading of necessary information (data exchange). Thereby, the user “0010” can browse the information of the subject person Ob in charge recorded in the database of the management server SV and can perform appropriate care or the like. Further, as described above, event information transmitted from the sensor box SB in the room in charge to the mobile terminal TA managed by the user can be confirmed.
　一方、ユーザ「００１０」が就業を終える際は、携帯端末ＴＡに表示されたログアウトボタン(不図示)を操作することで、ログアウト情報が入力される(図１１のステップＳ２０４)。すると、携帯端末ＴＡから管理サーバＳＶへ、ログアウト情報としてのユーザ名及び端末ＩＤを含むログアウト要求信号が送信される(Ｃ２２)。管理サーバＳＶは、ログアウト要求信号を受信すると、ステップＳ２０５でログアウト処理を実行する。以降、管理サーバＳＶは、ログアウト処理がなされた携帯端末ＴＡから情報の開示要求があっても，それに応答せず、またイベント情報を送信することもない。 On the other hand, when the user “0010” finishes working, logout information (not shown) displayed on the mobile terminal TA is operated to input logout information (step S204 in FIG. 11). Then, a logout request signal including a user name and terminal ID as logout information is transmitted from the portable terminal TA to the management server SV (C22). When receiving the logout request signal, the management server SV executes logout processing in step S205. Thereafter, the management server SV does not respond to an information disclosure request from the portable terminal TA that has undergone the logout process, and does not transmit event information.
