Description
本発明は、複数の独居老人等の見守りを必要とする被観察者の周辺にセンサーや緊急発報を行なう機器等を配置し、これら機器類からの情報をネットワーク経由でサーバーに集約する見守りシステムに関し、より詳細には、被観察者が所定の緊急発報条件に当てはまる場合に、緊急事態として自動的に被観察者の家族や保護者、主治医等の特定者に連絡し、これら特定者が被観察者と双方向の通信を行なうようにしたものである。 The present invention is a monitoring system in which a sensor or a device for performing an emergency alert is arranged around an observed person who needs to be watched by a plurality of elderly people living alone, and information from these devices is collected in a server via a network. In more detail, regarding the observed person, when the observed person falls under the prescribed emergency alert conditions, an emergency situation is automatically notified to the observed person's family, guardian, doctor, etc. Two-way communication is carried out with the observed person.
従来、老人等の被観察者の日常生活における状態や安否確認等を行なうためのシステムとしては、人感系センサーを使ったものやドップラー技術を応用したバイタル系センサーを用いたものが知られている。 Conventionally, as a system for confirming the state and safety of an observer such as an old person in daily life, one using a human sensor or one using a vital sensor applying Doppler technology is known. There is.
具体的には、人感系センサーを使ったものとしては、被観察者の居住空間に設置された人感センサーによって、被観察者の生活情報を収集し、一定時間反応がない場合には被観察者を呼び出し、被観察者からの応答がなければ近親者に安否確認の必要性を連絡するシステムが知られている。 Specifically, when using a human sensor, the human sensor installed in the living space of the observed person collects the living information of the observed person, and if there is no reaction for a certain period of time, There is known a system that calls an observer and informs a close relative of the necessity of confirming safety if there is no response from the observed person.
また、各宅内における被観察者の行動をセンサーで判定し、ダミーデータと暗号化によってプライバシーの保護が図られた前記被観察者のデータを基地局に送信し、基地局で被観察者の関係者に緊急連絡を行なうか否かを判断するようにしたシステムも知られている。 Also, the behavior of the person being observed in each home is determined by a sensor, the dummy data and the data of the person being observed whose privacy has been protected by encryption are transmitted to the base station, and the relationship between the person being observed at the base station. There is also known a system for determining whether or not to make an emergency contact with a person.
この他、被観察者が居住する各部屋にセンサーを取り付け、これらセンサーによって得られた被観察者の動きをデータ化して見守りを行なうシステムや多数のセンサーからの情報を加工し、該情報によって遠隔的な見守りを行なうシステムも知られている。 In addition, a sensor is installed in each room in which the person to be observed lives, and the information from the sensors and the system that monitors the movement of the person to be observed obtained by these sensors is processed, and the information is used to remotely control the information. There is also known a system for performing visual oversight.
一方、バイタル系センサーを用いたものとしては、ドップラーセンサーが出力する波形から正確な心拍数を算出したり、呼吸回数を計測したり、或は血管に向けて超音波を発し、その反射波から呼吸回数を算出するものが知られている。 On the other hand, when using a vital type sensor, the accurate heart rate is calculated from the waveform output by the Doppler sensor, the number of respirations is measured, or ultrasonic waves are emitted toward the blood vessel, and the reflected wave is used. It is known to calculate the number of breaths.
日本の高齢化社会において、日ごろ見守りを必要とする老人等が増加しているが、該老人等の日常生活を見守る人材の確保が困難な状況となっており、そのため、老人等が生活する個人住宅や集合住宅、或は介護施設等においては、遠隔での自動的な見守り体制や緊急事態の発生時における自動的な通報システムの構築が必須となってきている。 In Japan's aging society, the number of elderly people, etc. who need daily watching is increasing, but it is difficult to secure human resources who watch over their daily lives. In homes, condominiums, nursing facilities, etc., it has become essential to build a remote monitoring system and an automatic reporting system in the event of an emergency.
前項で述べた従来の見守りシステムは、いずれも各種センサーを用いて老人等の被観察者の日常生活を検知するものであるが、センサーによる個々の検知は画一的であるのに対して、被観察者は、日常生活で歩行が十分可能な人から寝たきりに近い人まで千差万別であるため、被観察者の個々の特性に合わせた適切な検知が十分に行われていないという問題がある。 The conventional monitoring system described in the previous section is one that detects the daily life of an observed person such as an old person using various sensors, but the individual detection by the sensor is uniform, whereas The number of observed persons varies from those who can walk enough in daily life to those who are nearly bedridden, so the problem that adequate detection according to the individual characteristics of the observed person is not performed sufficiently. There is.
具体的には、寝たきりに近い状態であって、自力での移動が困難な被観察者の場合、人感センサーによる検知では有効な判断が行えず、また逆に頻繁に移動を行なう被観察者の場合、バイタル系センサーでは被観察者が検知エリアの外に移動すると検知不可となる。また、緊急事態となった被観察者が自ら能動的にスイッチ類を押して緊急発報を行なうようなシステムでは、被観察者が転倒したり、意識を失った場合に緊急発報が行われないという問題が生ずる。そして、このような検知精度の問題は、見守りシステムに対する信頼性を大きく損ねると共に、当該システムの利用価値自体を低下させることとなっている。 Specifically, in the case of an observed person who is in a state close to bedridden and is difficult to move by himself, the detected person with the motion sensor cannot make an effective judgment, and conversely, the observed person who moves frequently. In such a case, the vital sensor cannot detect the subject if the subject moves outside the detection area. Also, in a system in which the person to be observed in an emergency actively presses switches to issue an emergency alert, when the person to be observed falls or loses consciousness, no emergency alert is issued. The problem arises. Then, such a problem of the detection accuracy seriously impairs the reliability of the watching system and reduces the utility value of the system itself.
また、見守りの検知精度を上げるために、例えば被観察者の日常生活を常時カメラで撮影し、その画像を観察することにより、被観察者の状態を検知することも可能であるが、この場合、被観察者の日常生活が常に第三者に見られているため、被観察者のプライバシーや人権上の問題が生ずる。 Further, in order to improve the detection accuracy of watching, for example, it is possible to detect the state of the observed person by constantly photographing the daily life of the observed person with a camera and observing the image. As the observed person's daily life is constantly seen by a third party, the observed person's privacy and human rights problems arise.

図９に示すように、見守り用サーバー（０００３）における緊急発報条件データベース（４００３）に記憶されている緊急発報条件の管理設定項目としては、被観察者のＩＤ番号と氏名、緊急発報のレベルや論理式、発報先の識別番号および現在のステイタス等が挙げられる。 As shown in FIG. 9, the emergency alert condition management setting items stored in the emergency alert condition database (4003) of the watching server (0003) include the ID number and name of the observed person, and the emergency alert. Level, logical expression, identification number of the report destination, current status, etc.
なお、図中「Ｄ」は主治医、「Ｆ」は家族、「Ｓ」は介護を担当するヘルパーやケアマネジャー等の保護者を示す。 In the figure, “D” indicates a doctor, “F” indicates a family, and “S” indicates a guardian such as a helper or a care manager in charge of care.
次に、図１０（ａ）（ｂ）（ｃ）に示すように、前記緊急発報条件に基づく緊急事態判定部（４００４）での判断例について述べると、例えば前記ドップラーセンサー（２００３）を被観察者のベッド下に設置して、被観察者の呼吸回数を計測し、これを１分ごとに見守り用サーバー （０００５）に送信する場合において、見守り用サーバー（０００５）側では送信されてきたデータの経時変化と、正常範囲内か否か、更に判定不可能の場合、他のセンサー類のデータとの照合によって、緊急発報条件の精度を高めるのである。 Next, as shown in FIGS. 10 (a), 10 (b) and 10 (c), a description will be given of an example of determination by the emergency situation determination unit (4004) based on the emergency alert condition. For example, the Doppler sensor (2003) When it is installed under the observer's bed and the number of respirations of the observed person is measured and sent to the watching server (0005) every one minute, it is sent on the watching server (0005) side. The accuracy of the emergency alerting condition is increased by collating the change with time of the data with the data of other sensors when it is not possible to determine whether it is within the normal range.
先ず図１０（ａ）のケースでは、被観察者の呼吸回数が突然、ゼロになった場合であって、呼吸回数が１分あたり１８回ずつ計測されていて、突然ゼロになったときに、他の人感センサー（２００２）やサーモカメラ（２００４）の検知データと併せて緊急事態の判定を行う。このケースでは、被観察者がベット上から離床した可能性と呼吸停止の可能性があり、人感センサー（２００２）で反応があった場合やサーモカメラ（２００４）での検知によって、緊急事態と判断しない。一方、これらセンサーによる検知がない場合、緊急事態と判断する。 First, in the case of FIG. 10A, when the number of respirations of the observed person suddenly becomes zero, the number of respirations is measured 18 times per minute, and when it suddenly becomes zero, An emergency situation is determined together with the detection data of other human sensor (2002) and thermo camera (2004). In this case, there is a possibility that the observed person has left the bed and there is a possibility that he / she will stop breathing, and if there is a reaction from the motion sensor (2002) or the detection by the thermo camera (2004), an emergency occurs. Do not judge. On the other hand, if there is no detection by these sensors, it is judged as an emergency.
次に、図１０（ｂ）の場合、呼吸回数が急激に低下しており、また図１０（ｃ）の場合は逆に呼吸回数が急激に増加しているが、いずれの場合も、被観察者の身体の急変が考えられるため、緊急事態と判断される。なお、呼吸回数に関しては、例えば毎分１０〜２４回を正常範囲としたり、被観察者によっては毎分１２〜２２回を閾値として、この範囲から外れた場合に緊急事態と判断する。 Next, in the case of FIG. 10 (b), the breathing rate sharply decreases, and conversely, in the case of FIG. 10 (c), the breathing rate sharply increases. It is judged that the situation is an emergency because a sudden change in the person's body may occur. Regarding the number of breaths, for example, 10 to 24 times per minute is set as a normal range, or 12 to 22 times per minute is set as a threshold depending on a person to be observed, and it is determined to be an emergency when it is out of this range.
次に、図１１に示すように、前記被観察者端末（０００１）における処理の一例について説明すると、ナースコールボタン等による緊急信号入力のステップ（Ｓ１１０１）の他に、人感センサーやドップラーセンサー等のセンサー類からのデータ入力Ａのステップ（Ｓ１１０２）と同じくセンサー類からのデータ入力Ｂのステップ（Ｓ１１０３）が一定時間の経過ステップ（Ｓ１１０４）を介して繰り返し処理されて、一定時間ごとに見守り用サーバー（０００５）へ前記データ入力Ａ・Ｂに基づくデータ送信ステップ（Ｓ１１０５）が実行される。また、このようなサイクルにおいて、前記ナースコールボタン等による緊急信号入力のステップ（Ｓ１１０１）が最優先の緊急事態として割り込みがかけられて、見守り用サーバー（０００５）への緊急発報の送信ステップ（Ｓ１１０５）が即座に実行される。 Next, as shown in FIG. 11, an example of processing in the observed terminal (0001) will be described. In addition to the step of inputting an emergency signal by a nurse call button (S1101), a human sensor, a Doppler sensor, etc. The step of data input A from the sensors (S1102) and the step of data input B from the sensors (S1103) are repeatedly processed through the step of elapse of a certain time (S1104) to monitor every certain time. A data transmission step (S1105) based on the data input A / B is executed to the server (0005). Further, in such a cycle, the step of inputting the emergency signal by the nurse call button or the like (S1101) is interrupted as the highest priority emergency situation, and the step of transmitting the emergency report to the watching server (0005) ( S1105) is immediately executed.

The step of receiving data from the observed terminal (0001) (S1201) and the received data have a predetermined emergency alert condition. (S1202), a step (S1203) of issuing a notification to a specific person terminal (0002) corresponding to the case where the emergency notification condition is met, and an observer terminal after the notification. There is a step (S1204) of connecting the (0001) and a specific terminal (0002) of the pair to execute a video conference by video and audio. Further, the emergency notification condition database (4003) is used for the determination step (S1202) described above, and the terminal information database (4002) is used for the step (S1203) of notifying the specific person terminal (0002). .
図１３に示すように、本実施形態に係る見守りシステムを用いた見守り方法について説明すると、被観察者端末（０００１）に接続された観察機器によって被観察者を検知するステップ（Ｓ１３０１）と、検知した観察データを見守りサーバーに送信するステップ（Ｓ１３０２）と、見守りサーバーで受信した観察データが所定の緊急発報条件に合致するか否かを判断するステップ（Ｓ１３０３）と、所定の緊急発報条件に合致する場合に被観察者端末（０００１）と対の特定者端末（０００２）〜（０００４）に緊急発報を行うステップ（Ｓ１３０４）と、緊急発報後に特定者端末（０００１）と被観察者端末（０００２）〜（０００４）とを映像および音声で双方向に接続して安否等の最終確認を行うステップ（Ｓ１３０５）を有する。そして、前述した通り、用いた見守り方法を実行するにあたり、被観察者の要介護度に合わせて複数段階の検知レベルおよび緊急発報条件を設定する。 As shown in FIG. 13, a watching method using the watching system according to the present embodiment will be described.
