Abstract

Provided is a communication system capable of easily realizing the function of a terminal while reducing the burden on a caregiver or the like. When a portable terminal TA transmits a login request signal to a management server SV, the management server SV responds to the portable terminal TA by transmitting a response signal thereto that contains permission information enabling an external line call over a PBX, or non-permission information disabling the external line call. The portable terminal TA runs a home application upon receiving the response signal, and: when the response signal contains permission information, enables a jump operation for running a call application on a TA input unit 35 while running the home application; when the call application is run as a result of a user operating the TA input unit 35 and performing the jump operation, makes it possible to connect to an external public line through the PBX, and consequently, makes it possible to place an external line call via a voice call device; and when the response signal contains non-permission information, disables the jump operation.

　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、異常検出装置が要介護者などの監視対象の異常を検出したときに、監視対象の画像を撮像して、ネット等を介して外部の端末へと前記監視対象の画像データを送信することで、監視対象の現状を遠隔的に監視する技術が開示されている。 Patent Document 1 discloses that when an abnormality detection device detects an abnormality of a monitoring target such as a care recipient, the monitoring target image data is captured and transmitted to an external terminal via a network or the like. A technique for remotely monitoring the current status of a monitoring target by transmitting a message is disclosed.

　ところで、近年においては、いわゆるスマートフォンと呼ばれる携帯端末の性能が向上しており、ＰＣ並みの性能を有するにもかかわらず、介護士等のポケットに携帯できる程度に小型化されたものが市販されている。よって、介護士等は携帯端末を携帯したまま施設内を巡回し、必要な要介護者の介護を実際に行いつつ、これと並行して別の要介護者を、例えば特許文献１の技術を応用した携帯端末を介して遠隔的に監視することができる。これにより、少ない数の介護士等により多くの要介護者を介護することができ、同時に介護士等の負担を軽減することができる。このような遠隔的な監視は、要介護者の画像データを取得するカメラと、カメラから画像データを送信する送信装置と、監視アプリケーションをインストールした携帯端末とを含む監視システムにより実現できる。 By the way, in recent years, the performance of mobile terminals called so-called smart phones has been improved, and even though it has the performance of a PC, it has been marketed that is small enough to be carried in a pocket of a caregiver or the like. Yes. Therefore, caregivers or the like travel around the facility while carrying the mobile terminal, and actually perform the care of the necessary care recipient, while concurrently providing another care recipient, for example, the technique of Patent Document 1. It can be monitored remotely via the applied mobile terminal. As a result, a large number of care recipients can be cared for by a small number of caregivers and the burden on the caregivers can be reduced at the same time. Such remote monitoring can be realized by a monitoring system including a camera that acquires image data of a care recipient, a transmission device that transmits image data from the camera, and a mobile terminal in which a monitoring application is installed.
　一方、特許文献２に示すように、外部の公衆回線と接続された構内交換機(Private Branch eXchange，以下ＰＢＸとする)をコンピュータと連携させる技術も知られている。特許文献２の技術を用いれば、施設内に設けられたＰＢＸと携帯端末とを連携させて高度のサービスを提供可能になる。例えば、携帯端末にて外線用の通話アプリケーションを実行することで、携帯端末から外線電話をかけることができる。 On the other hand, as shown in Patent Document 2, a technology is also known in which a private branch exchange (Private Branch eXchange, hereinafter referred to as PBX) connected to an external public line is linked with a computer. If the technology of Patent Document 2 is used, it is possible to provide a high-level service by linking a PBX provided in a facility with a mobile terminal. For example, by executing a call application for an outside line on a mobile terminal, an external line call can be made from the mobile terminal.
　ここで、一般的な介護施設等は、医師や看護婦等が常駐していないことが多い。従って、このような介護施設で要介護者に異変が生じた場合、迅速に外部の病院や家族等に連絡し必要な処置を講じなくてはなくてはならないとされる。ところが、要介護者の画像データを携帯端末で受信して監視している場合、通話アプリケーションとは異なる監視アプリケーションが実行中であることから、外線電話を可能にするためには、まず通話アプリケーションに切り換えることが必要となる。しかしながら、携帯端末の操作に不慣れな介護士の場合、通話アプリケーションに切り換える操作に手間取り、外部への連絡が遅れることも懸念される。かかる問題は、携帯端末に限らず固定端末にて監視する場合でも起こりうる。 Here, doctors and nurses are often not resident in general care facilities. Therefore, when a change occurs in a care recipient in such a care facility, it is necessary to promptly contact an external hospital or family and take necessary measures. However, when the image data of the care recipient is received and monitored by a mobile terminal, a monitoring application different from the call application is running. It is necessary to switch. However, in the case of a caregiver who is unfamiliar with the operation of the mobile terminal, there is a concern that the operation for switching to the call application takes time and delays in contacting the outside. Such a problem may occur even when monitoring is performed with a fixed terminal as well as a portable terminal.
　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しつつも、容易に端末の機能を発揮できる通信システムを提供することを目的とする。 This invention is made in view of the said situation, and it aims at providing the communication system which can exhibit the function of a terminal easily, reducing the burden of a caregiver etc.

　前記端末と通信可能であって、外部の公衆回線と通信可能に接続されたＰＢＸとを有する通信システムであって、

The TA communication IF unit 33 receives a communication signal from the management server SV or the like via the network NW, extracts data from the received communication signal, and has a format in which the TA control processing unit 31 can process the extracted data. And output to the TA control processing unit 31.
　ＴＡ記憶部３２は、ＴＡ制御処理部３１に接続され、ＴＡ制御処理部３１の制御に従って、各種のプログラム（対象者Ｏｂを監視するホームアプリケーション、外線通話を可能にする通話アプリケーション等）および各種のデータを記憶する回路である。前記各種のプログラムには、表示に関する動作を処理する表示処理プログラム等が含まれる。前記各種のデータでは、ＴＡ表示部３６に表示される画面情報等の各データが含まれる。ＴＡ記憶部３２は、例えばＲＯＭやＥＥＰＲＯＭ等を備える。ＴＡ記憶部３２は、前記所定のプログラムの実行中に生じるデータ等を記憶するいわゆるＴＡ制御処理部３１のワーキングメモリとなるＲＡＭ等を含む。そして、ＴＡ記憶部３２は、上述の各情報を記憶するために、機能的に表示画面記憶部３２１を備えている。 The TA storage unit 32 is connected to the TA control processing unit 31, and according to the control of the TA control processing unit 31, various programs (home application for monitoring the target person Ob, call application for enabling an external call, etc.) and various types of programs A circuit for storing data. The various programs include a display processing program for processing operations related to display. The various data includes data such as screen information displayed on the TA display unit 36. The TA storage unit 32 includes, for example, a ROM and an EEPROM. The TA storage unit 32 includes a RAM that serves as a working memory of a so-called TA control processing unit 31 that stores data generated during execution of the predetermined program. The TA storage unit 32 functionally includes a display screen storage unit 321 in order to store the above-described information.
　表示画面記憶部３２１は、ＴＡ制御処理部３１における後述の表示処理部３１２１の制御に従って、ＴＡ表示部３６に表示するための画面情報を記憶するものである。 The display screen storage unit 321 stores screen information to be displayed on the TA display unit 36 in accordance with the control of the display processing unit 3121 described later in the TA control processing unit 31.
　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、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、ＴＡ記憶部３２に記憶されたホームアプリケーション及び通話アプリケーションを含む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を制御し、ＴＡ処理部３１２は表示処理部３１２１を制御する。 The TA control processing unit 31 is a circuit for processing information. The TA control processing unit 31 includes, for example, a CPU and its peripheral circuits. The TA control processing unit 31 controls the TA control unit 311 and the TA processing unit 312 by executing a control processing program including a home application and a call application stored in the TA storage unit 32. The TA processing unit 312 The display processing unit 3121 is controlled.
　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、実施形態における介護支援システムの動作について説明する。「Ａｎｄｒｏｉｄ（登録商標）」等のＯＳを使用する汎用の携帯端末は、インストールされた複数のアプリケーションを実行することができるので、専用品に比べて低コストで本介護支援システムに使用することができる。一方、このような携帯端末では、その汎用性を高めるために、アプリケーションを切り換える際には、一旦ＯＳのホーム画面に戻す操作が必要になる。 Next, the operation of the care support system in the embodiment will be described. Since a general-purpose portable terminal using an OS such as “Android (registered trademark)” can execute a plurality of installed applications, it can be used in the care support system at a lower cost than a dedicated product. it can. On the other hand, in order to increase the versatility of such a portable terminal, when switching applications, it is necessary to once return to the OS home screen.
　例えば、対象者Ｏｂを監視するホームアプリケーションを実行している間、携帯端末ＴＡの表示画面には、後述する図５（ａ）に示す待ち受け画面が表示されることとなる。ここで、介護士（ユーザー）が外線電話をかけようとした場合、「Ａｎｄｒｏｉｄ（登録商標）」等のＯＳの通常手順に従えば、外線通話を可能にする通話アプリケーションに切り換えるため、一旦ＯＳのホーム画面に戻し、表示されたアイコンのうち対応するものをタップするなどして、通話アプリケーションを起動する操作を行わなくてはならない。しかしながら、かかる操作は複雑であり、携帯端末の操作に不慣れな介護士は操作に手間取る恐れがある。本実施形態によれば、操作に不慣れな介護士でも容易に外線通話を行えるようにできる。 For example, while a home application for monitoring the target person Ob is being executed, a standby screen shown in FIG. 5A to be described later is displayed on the display screen of the portable terminal TA. Here, when a caregiver (user) tries to make an outside line call, according to the normal procedure of the OS such as “Android (registered trademark)”, the OS is temporarily switched to a call application that enables an outside line call. You must return to the home screen and tap the corresponding icon among the displayed icons to start the call application. However, such an operation is complicated, and a caregiver who is unfamiliar with the operation of the mobile terminal may take time. According to the present embodiment, a caregiver who is unfamiliar with the operation can easily make an outside line call.
　ここで、本実施形態にかかる介護支援システムＭＳ全体について説明するが、センサボックスＳＢの起動により、その制御処理プログラムの実行によって監視動作が開始される。まず、勤務を開始した介護士の一人（ユーザー００１０）が、自分が使う携帯端末ＴＡのメインスイッチをオン操作する。すると、後述する図４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、メインスイッチオン操作と同時に対象者Ｏｂを監視するホームアプリケーションがＯＳ上で自動的に起動して、図４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。なお、アプリケーションの起動方法はこれに限定されず、ＯＳの待ち受け画面上に配置された当該アプリのアイコンをタップすることにより、対象者Ｏｂを監視するホームアプリケーションが起動し図４に示すログイン画面が表示されても良い。前者の場合は、端末を個人専用とせず、またユーザーにＯＳの存在を感じさせず特定用途専用端末のシンプルなユーザーインターフェイスを提供できるメリットがあり、後者の場合は各担当者が自前のスマホ等の端末に当該アプリをインストールして利用できることにより、個人携帯との２台持ちになることを回避できるメリットがある。 Here, the overall care support system MS according to the present embodiment will be described. When the sensor box SB is activated, a monitoring operation is started by executing the control processing program. First, one of the caregivers who started working (user 0010) turns on the main switch of the portable terminal TA used by the caregiver. Then, a login screen as shown in FIG. 4 to be described later is displayed. In a mobile terminal using an OS such as “Android (registered trademark)”, a home application that monitors the target person Ob is automatically started on the OS simultaneously with the main switch-on operation, and a login screen as shown in FIG. Customized to display first. Note that the application activation method is not limited to this, and by tapping the icon of the application arranged on the standby screen of the OS, the home application for monitoring the target person Ob is activated and the login screen shown in FIG. 4 is displayed. It may be displayed. In the former case, there is an advantage that the terminal is not dedicated to the individual, and there is an advantage that it is possible to provide a simple user interface of the special purpose terminal without making the user feel the presence of the OS. In the latter case, each person in charge has his own smartphone etc. By installing and using the application on the terminal, there is an advantage that it is possible to avoid having two units with a personal mobile phone.
　図３は、管理サーバＳＶと携帯端末ＴＡとの間の通信を示す梯子チャートである。図３のステップＳ１０１で、ユーザーによりログイン操作が行われることで、システムの動作が開始する。より具体的には，図４に示すログイン画面にて、ユーザーが「ユーザー名」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ー名「ユーザー００１０」をタップしてユーザー名（ユーザー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。その後ユーザーは、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。 FIG. 3 is a ladder chart showing communication between the management server SV and the portable terminal TA. In step S101 in FIG. 3, the user performs a login operation to start the operation of the 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. 4, a plurality of options are displayed. A user name (user ID) is selected by tapping the name “user 0010”, and a four-digit number is input into 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３におけるステップＳ１０１のログイン操作により、ユーザー情報としてのユーザー名や端末ＩＤ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（Ｃ１１）。ログイン要求信号を受信した管理サーバＳＶは、内蔵メモリに記憶したデータベース内を参照し、ユーザー名とパスが一致するか否かを確認する（ステップＳ１０２）。ユーザー名とパスが一致しなければ、管理サーバＳＶは、失敗信号を携帯端末ＴＡへと送信する（Ｃ１２）。これを受信した携帯端末ＴＡは、ステップＳ１０３でログイン失敗表示（不図示）を表示するから、ログインするためには、ステップＳ１０１で再度ログイン操作を実行する必要がある。 3, a login request signal including a user name, user ID, and the like as user information is transmitted from the portable terminal TA to the management server SV (C11). The management server SV that has received the login request signal refers to the database stored in the built-in memory, and checks whether the user name and the path match (step S102). If the user name and the path do not match, the management server SV transmits a failure signal to the portable terminal TA (C12). The mobile terminal TA that has received this displays a login failure display (not shown) in step S103, and therefore, in order to log in, it is necessary to execute the login operation again in step S101.
　一方、ユーザー名とパスが一致していた場合、管理サーバＳＶは、ステップＳ１０４で携帯端末ＴＡをＰＢＸに接続可能か否かを判定する。ここで、ＰＢＸの接続を可能とする判定条件は以下の通りである。
（１）当該施設のネットワークＮＷがＰＢＸを介して外部の公衆回線に通信可能に接続されていること。
（２）ログイン要求信号を送信した携帯端末ＴＡからＰＢＸを介して外線通話を行うことを許可されていること。 On the other hand, if the user name and the path match, the management server SV determines whether or not the portable terminal TA can be connected to the PBX in step S104. Here, the determination conditions for enabling PBX connection are as follows.
(1) The network NW of the facility is communicatively connected to an external public line via the PBX.
(2) The mobile terminal TA that has transmitted the login request signal is permitted to make an outside line call via the PBX.
　条件（１）の判定については、当該施設のネットワークＮＷがＰＢＸを介して外部の公衆回線に接続されているか否か、予め管理サーバＳＶに記憶されているので、それを参照すれば良い。一方、条件（２）の判定については、例えば介護士のリーダーなど、限定されたユーザーのみに外線通話を許可する場合があることを考慮したものである。そのような場合、管理サーバＳＶは外線通話を許可するユーザー名のリストを予め記憶しており、ログイン要求信号に含まれたユーザー名（ユーザー情報）を、記憶しているリストと照合して、その携帯端末ＴＡをＰＢＸに接続可能か否か判断することができる。尚、当該施設において全てのユーザーに外線通話を許可する場合、条件（２）は判定する必要がない。 Regarding the determination of the condition (1), whether or not the network NW of the facility is connected to an external public line via the PBX is stored in advance in the management server SV, and may be referred to. On the other hand, the determination of the condition (2) takes into consideration that only a limited user, such as a caregiver's leader, may be permitted to make an outside line call. In such a case, the management server SV stores in advance a list of user names that are permitted to make external calls, and compares the user name (user information) included in the login request signal with the stored list, It can be determined whether or not the portable terminal TA can be connected to the PBX. In addition, when permitting an outside line call to all users in the facility, it is not necessary to determine the condition (2).
　管理サーバＳＶが、携帯端末ＴＡをＰＢＸに接続可能であると判断した場合、ステップＳ１０５で許可情報を含む回答信号を生成する。一方、管理サーバＳＶが、携帯端末ＴＡをＰＢＸに接続できないと判断した場合、ステップＳ１０６で不許可情報を含む回答信号を生成する。生成された回答信号は、管理サーバＳＶから携帯端末ＴＡへと送信される（Ｃ１３）。 When the management server SV determines that the portable terminal TA can be connected to the PBX, a response signal including permission information is generated in step S105. On the other hand, if the management server SV determines that the portable terminal TA cannot be connected to the PBX, a response signal including non-permission information is generated in step S106. The generated answer signal is transmitted from the management server SV to the portable terminal TA (C13).
　回答信号を受信した携帯端末ＴＡは、ステップＳ１０７で、予めインストールされている複数のアプリケーションのうち、ホームアプリケーションを立ち上げて、介護士による対象者Ｏｂの監視（見守り）を支援する。より具体的には、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３６に表示する。この待受け画面は、例えば、図５（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６１３、当該携帯端末ＴＡにログインしているユーザー名６１４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しながら、携帯端末ＴＡは、ＴＡ制御部３１１によってＴＡ通信ＩＦ部３３で、管理サーバＳＶから送信される通信信号を待つこととなる。 In step S107, the portable terminal TA that has received the answer signal starts up a home application among a plurality of applications installed in advance, and supports monitoring (watching) of the target person Ob by the caregiver. More specifically, the portable terminal TA causes the TA processing unit 312 to display a standby screen for waiting for a communication signal addressed to the mobile terminal TA on the TA display unit 36. For example, as shown in FIG. 5A, 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 613, a user name 614 logged in to the portable terminal TA, and the like. While displaying such a standby screen, the portable terminal TA waits for a communication signal transmitted from the management server SV at the TA communication IF unit 33 by the TA control unit 311.
　本実施形態で行う見守り動作について説明する。図示を省略するが、各対象者Ｏｂの監視を行うセンサボックスＳＢは、カメラ部で対象者Ｏｂの画像データを取得しつつ、その画像データを画像解析する。この解析の結果、所定のイベント（起床、離床、転倒、転落）を検出したときは、センサボックスＳＢは、イベント前後の画像データを内蔵メモリに記憶すると共に、どの種類の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。 The watching operation performed in this embodiment will be described. Although illustration is omitted, the sensor box SB that monitors each subject Ob obtains image data of the subject Ob by the camera unit and analyzes the image data. As a result of this analysis, when a predetermined event (getting up, getting out of bed, falling, falling) is detected, the sensor box SB stores the image data before and after the event in the built-in memory and indicates what kind of event has occurred. The notification information including the event information to be shown and the communication address is transmitted to the management server SV via the network NW.
　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、通知信号に含まれているセンサボックスＳＢの情報に基づいて、居住者が誰か（ここでは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：特定の状態）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、携帯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）、携帯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。 When such a notification signal is transmitted from the sensor box SB, the management server SV determines who is the resident (here, Mr. B) based on the information of the sensor box SB included in the notification signal, Further, it is determined from the event information of the notification signal whether the notification event corresponds to the resident (Mr. B) (in this case, falls or falls: a specific state). When the event information of the received notification signal indicates a notification event, it is determined to notify the mobile 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 mobile terminal, and the next notification signal is awaited.
　管理サーバＳＶが、端末への通知を決定した場合、居住者（Ｂさん）を担当する介護士の携帯端末ＴＡを選定し、更に、ＲＭ－２号室で転倒又は転落が生じた情報を含む通知信号（イベント信号）を、選定した携帯端末へ送信する。 When the management server SV decides to notify the terminal, the mobile terminal TA of the caregiver in charge of the resident (Mr. B) is selected, and the notification including information that the RM-2 room has fallen or falls. A signal (event signal) is transmitted to the selected portable terminal.
　このような通知信号が管理サーバ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５（ｂ）に示すものに切り替える。図５（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）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。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。 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, for example, the one shown in FIG. In the example shown in FIG. 5B, in the main area 612, the name of the room where the event occurred (RM-2 room), the name of the resident in the room (B-like), and the icon IC1 indicating a fall or fall The time difference (0 minute) between the notification time and the current time is displayed. 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（タップともいう）すると、携帯端末ＴＡのＴＡ入力部３５が反応し、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にリクエスト信号が送信される。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 (also referred to as a tap), the TA input unit 35 of the mobile terminal TA reacts and the TA control unit 311 determines that an image request has been made, and the TA communication IF unit. A request signal is transmitted to the management server SV via the network NW. 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、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、センサボックスＳＢから画像データを読み出して、ネットワークＮＷを介して管理サーバＳＶに送信する。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、カメラ部で撮像してなるライブ映像をエンコードして、そのセンサボックスＳＢからネットワークＮＷを介して管理サーバＳＶに送信する。 The sensor box SB that has received the request signal determines the request type in the request signal. 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. The image data is read from the sensor box SB and transmitted to the management server SV via the network NW. 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. The live video imaged by the camera unit is encoded and transmitted from the sensor box SB to the management server SV via the network NW.
　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５（ｃ）に示すものに切り替える。記憶映像を要求した図５（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、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の音入出力部（不図示）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。 The portable terminal TA that has received the image data switches the screen display of the TA display unit 36 to, for example, the one shown in FIG. In the example shown in FIG. 5C in which the stored video is requested, the image (video) IMG of Mr. B before and after falling down in the RM-2 room is displayed in the main area 612. The person 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 talk directly via the sound input / output unit (not shown) of the sensor box SB. Therefore, the situation can be judged accurately.
　尚、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号室に近い場所にいるときは、画像を見ることなく直ちに駆けつけることができる。従って、そのような場合、ボタンＢ１をタッチすることで、例えば固定端末ＳＰに、介護士が直接対応する旨の情報が送信されることとなる。 In addition, when the caregiver who sees the displayed icon IC1 is near the RM-2 room where the event occurs, the caregiver can rush immediately without looking at the image. Therefore, in such a case, by touching the button B1, for example, information indicating that the caregiver directly responds to the fixed terminal SP is transmitted.
　ところで、図５に示す画面のいずれかが表示されているときに、例えば介護士は、同僚に内線電話をかけたり、或いは外部の病院や居住者の家族等に外線電話をかけたい場合がある。かかる場合、携帯端末ＴＡから直接外線電話をかけることができると便利であるが、当該施設が携帯端末ＴＡから外線通話を行うことに対応していない場合もある。そこで、以下のように制御を行っている。 By the way, when one of the screens shown in FIG. 5 is displayed, for example, a caregiver may want to make an extension call to a colleague or to make an outside call to an outside hospital, a resident family, or the like. . In such a case, it is convenient if an outside line call can be made directly from the mobile terminal TA, but there are cases where the facility does not support making an outside line call from the mobile terminal TA. Therefore, the control is performed as follows.
　図５において、介護士は、携帯端末ＴＡのＴＡ表示部３６に表示されたメニューバー領域６１１のアイコンＩＣ２をタップすることで、ホームアプリケーションにおける通話機能が有効になり（図３のステップＳ１０８でＹｅｓ）、以下のように表示画面が切り替わる。より具体的にはステップＳ１０９で、ＴＡ制御処理部３１が、管理サーバＳＶからの回答信号に許可情報が含まれているか否か判断し、回答信号に許可情報が含まれていた場合、ステップＳ１１０で、ＴＡ処理部３１２が通話アプリケーションに従って、図６（ａ）に示す画面（表示画面１）をメイン領域６１２に表示する。一方、回答信号に不許可情報が含まれていた場合、ステップＳ１１１で、ＴＡ処理部３１２が通話アプリケーションに従って、図７に示す画面（表示画面２）をメイン領域６１２に表示する。 In FIG. 5, the caregiver taps the icon IC2 in the menu bar area 611 displayed on the TA display unit 36 of the portable terminal TA, thereby enabling the call function in the home application (Yes in step S108 in FIG. 3). ), The display screen changes as follows. More specifically, in step S109, the TA control processing unit 31 determines whether or not permission information is included in the answer signal from the management server SV. If the permission information is included in the answer signal, step S110 is performed. Then, the TA processing unit 312 displays the screen (display screen 1) shown in FIG. 6A in the main area 612 according to the call application. On the other hand, if the disapproval information is included in the answer signal, in step S111, the TA processing unit 312 displays the screen (display screen 2) shown in FIG.
　図６（ａ）に示す画面では、管理サーバＳＶにログインしており内線通話が可能なユーザー名０００１～０００３，０００５，０００６（０００４はログインしていないので内線接続不可）のリスト及び外線ボタンＢ１２が表示される。内線電話をかけようとする場合、介護士は表示された外線ボタンＢ１２をタップすることなく（ステップＳ１１２でＮｏ）、表示されたユーザー名をタップして選択し、更に表示されたアイコンＩＣ４をタップすることで、選択した相手に内線電話をかけることができ、ＴＡ音入出力部３４を介して会話を行える（ステップＳ１１５）。 In the screen shown in FIG. 6A, a list of user names 0001 to 0003, 0005, and 0006 that are logged in to the management server SV and can make extension calls (external connection is impossible because 0004 is not logged in) and an external button B12 Is displayed. When trying to make an extension call, the caregiver taps and selects the displayed user name without tapping the displayed outside line button B12 (No in step S112), and further taps the icon IC4 displayed. By doing so, it is possible to make an extension call to the selected partner and to perform a conversation via the TA sound input / output unit 34 (step S115).
　一方、外線電話をかけようとする場合、介護士は表示された外線ボタンＢ１２をタップする（ステップＳ１１２でＹｅｓ）。すると、ステップＳ１１３において、ＴＡ処理部３１２は、通話アプリケーションの起動を行い（すなわち、ホームアプリケーションから通話アプリケーションへのジャンプ動作が行われ）、図６（ｂ）に示す画面をメイン領域６１２に表示する。そこで、介護士は表示された数字キーＮＫをタップして、所望の外線番号を入力し、更に表示されたアイコンＩＣ４をタップすることで、選択した相手に外線電話をかけることができ、ＴＡ音入出力部３４を介して会話を行える（ステップＳ１１４）。これにより操作に不慣れな介護士でも、容易に外線電話をかけることができる。尚、通話終了後は、アイコンＩＣ５をタップすることで回線遮断動作が行われる。これにより通話アプリケーションが終了し、ホームアプリケーションに復帰する。 On the other hand, when trying to make an outside line call, the caregiver taps the displayed outside line button B12 (Yes in step S112). In step S113, the TA processing unit 312 activates the call application (that is, a jump operation from the home application to the call application is performed), and displays the screen illustrated in FIG. 6B in the main area 612. . Therefore, the caregiver can tap the displayed number key NK, enter the desired outside line number, and tap the displayed icon IC4 to make an outside line call to the selected partner, and the TA sound A conversation can be performed via the input / output unit 34 (step S114). As a result, even a caregiver who is unfamiliar with the operation can easily make an outside line call. After the call is finished, the line blocking operation is performed by tapping the icon IC5. This terminates the call application and returns to the home application.

Therefore, when the screen shown in FIG. 7 is displayed, it can be understood that the caregiver cannot make an outside line call. Thus, the caregiver can select the displayed user name by tapping, and further tap the displayed icon IC4 to make an extension call to the selected partner, via the TA sound input / output unit 34. A conversation can be performed (step S115). The caregiver can return to the screen based on the home application (FIG. 5A) by tapping the icon IC3 in the menu bar area 611 displayed on the TA display unit 36 of the portable terminal TA.
