Description

生体情報取得システム、生体情報送信装置、生体情報受信装置及びプログラムBiometric information acquisition system, biometric information transmitter, biometric information receiver and program
　本発明は、生体情報取得システム、生体情報送信装置、生体情報受信装置及びプログラムに関する。 The present invention relates to a biometric information acquisition system, a biometric information transmitting device, a biometric information receiving device, and a program.
　従来、被看護者の生体情報を検出するセンサー装置から受信装置に生体情報を送信する技術が知られている（例えば、特許文献１を参照）。 Conventionally, a technique of transmitting biometric information from a sensor device that detects biometric information of a nurse to a receiving device has been known (see, for example, Patent Document 1).
特開２００４－１１０４８６号公報Japanese Unexamined Patent Publication No. 2004-110486
　従来のセンサー装置は、検出した生体情報を特定の受信装置に対して送信していた。センサー装置が特定の受信装置に生体情報を送信する場合、センサー装置と前記受信装置との間で通信コネクションを確立した後に生体情報を送信する必要があった。 The conventional sensor device transmits the detected biometric information to a specific receiving device. When the sensor device transmits biometric information to a specific receiving device, it is necessary to transmit the biometric information after establishing a communication connection between the sensor device and the receiving device.
　ところが、複数のセンサー装置が特定の受信装置と通信する環境においては、１台のセンサー装置が当該受信装置との間でコネクションを確立させた状態で生体情報を送信している間は、他のセンサー装置が当該受信装置に生体情報を送信することができなかった。その結果、当該受信装置とは別の受信装置を用意し、他のセンサー装置が別の受信装置との間で通信しない限り、他のセンサー装置を装着している人の生体情報が変化しても、他のセンサー装置は、変化したことをリアルタイムで受信装置に通知することができないという問題があった。 However, in an environment in which a plurality of sensor devices communicate with a specific receiving device, while one sensor device transmits biometric information while establishing a connection with the receiving device, another sensor device is used. The sensor device was unable to transmit biometric information to the receiver. As a result, unless a receiving device different from the receiving device is prepared and the other sensor device communicates with the other receiving device, the biometric information of the person wearing the other sensor device changes. However, there is a problem that other sensor devices cannot notify the receiving device of the change in real time.
　そこで、本発明はこれらの点に鑑みてなされたものであり、多数の人の生体情報をリアルタイムで監視しやすくすることを目的とする。 Therefore, the present invention has been made in view of these points, and an object of the present invention is to facilitate real-time monitoring of biometric information of a large number of people.
　本発明の第１の態様に係る生体情報取得システムは、人に装着され、前記人の生体情報を送信する生体情報送信装置と、複数の前記生体情報送信装置から前記生体情報を受信する生体情報受信装置と、を備える生体情報取得システムであって、複数の前記生体情報送信装置のそれぞれは、前記生体情報を取得する生体情報取得部と、前記生体情報取得部が取得した前記生体情報に基づいて作成した生体データを含み、前記生体データの送信先が指定されていない報知パケットを所定の送信間隔で送信するデータ送信部と、を有する。 The biometric information acquisition system according to the first aspect of the present invention includes a biometric information transmitting device that is worn by a person and transmits the biometric information of the person, and biometric information that receives the biometric information from a plurality of the biometric information transmitting devices. A biometric information acquisition system including a receiving device, each of the plurality of biometric information transmitting devices is based on a biometric information acquisition unit that acquires the biometric information and the biometric information acquired by the biometric information acquisition unit. It has a data transmission unit that includes the biometric data created in the above process and transmits broadcast packets for which the destination of the biometric data is not specified at predetermined transmission intervals.
　前記生体情報受信装置は、前記生体情報送信装置が送信した前記報知パケットを受信するデータ受信部と、前記データ受信部が受信した前記報知パケットに含まれる前記生体データが示す前記生体情報の異常の有無を判定する判定部と、前記判定部が前記生体情報に異常があると判定した場合に、前記生体データを送信した前記生体情報送信装置に対して、前記生体データよりも多くの情報を含む詳細データを要求するための要求パケットを前記生体情報送信装置に送信する要求部と、を有する。 The biometric information receiving device includes a data receiving unit that receives the broadcast packet transmitted by the biometric information transmitting device, and an abnormality of the biometric information indicated by the biometric data included in the broadcast packet received by the data receiving unit. When the determination unit determines the presence or absence and the determination unit determines that the biometric information is abnormal, the biometric information transmitting device that has transmitted the biometric data includes more information than the biometric data. It has a request unit for transmitting a request packet for requesting detailed data to the biometric information transmission device.

Further, the first communication unit 21 transmits a message for requesting detailed data to the biometric information transmission device 1 based on the instruction from the request unit 243.
　第２通信部２２は、ＬＡＮ（Local Area Network）又はインターネット等のネットワークを介して監視装置３との間でデータを送受信するための通信コントローラを有する。第２通信部２２は、監視装置３に生体データを送信したり警告情報を送信したりする。 The second communication unit 22 has a communication controller for transmitting and receiving data to and from the monitoring device 3 via a network such as a LAN (Local Area Network) or the Internet. The second communication unit 22 transmits biometric data and warning information to the monitoring device 3.
　記憶部２３は、ＲＯＭ、ＲＡＭ及びハードディスク等の記憶媒体を有する。記憶部２３は、制御部２４が実行するプログラムを記憶している。また、記憶部２３は、生体情報送信装置１から受信した生体情報を一時的に記憶する。 The storage unit 23 has a storage medium such as a ROM, RAM, and a hard disk. The storage unit 23 stores a program executed by the control unit 24. In addition, the storage unit 23 temporarily stores the biometric information received from the biometric information transmitting device 1.
　制御部２４は、例えばＣＰＵを有する。制御部２４は、記憶部２３に記憶されたプログラムを実行することにより、データ受信部２４１、判定部２４２及び要求部２４３として機能する。 The control unit 24 has, for example, a CPU. The control unit 24 functions as a data receiving unit 241 and a determination unit 242 and a requesting unit 243 by executing the program stored in the storage unit 23.
　データ受信部２４１は、第１通信部２１を介して、生体情報送信装置１が送信した報知パケットに含まれる簡易生体データを受信する。また、データ受信部２４１は、詳細データを要求した生体情報送信装置１が送信した詳細生体データを受信する。データ受信部２４１は、第１通信部２１が記憶部２３に記憶させた簡易生体データ及び詳細生体データを取得してもよい。 The data receiving unit 241 receives the simple biometric data included in the broadcast packet transmitted by the biometric information transmitting device 1 via the first communication unit 21. In addition, the data receiving unit 241 receives the detailed biometric data transmitted by the biometric information transmitting device 1 that requested the detailed data. The data receiving unit 241 may acquire the simple biometric data and the detailed biometric data stored in the storage unit 23 by the first communication unit 21.
　判定部２４２は、データ受信部２４１が受信した報知パケットに含まれる簡易生体データが示す生体情報の異常の有無を判定する。判定部２４２は、例えば、データ受信部２４１が受信した報知パケットに含まれていた第１簡易生体データと、当該報知パケットを送信した生体情報送信装置１が過去に送信した報知パケットに含まれていた第２簡易生体データとを比較し、第１簡易生体データと第２簡易生体データとの差が閾値以上である場合に異常があると判定する。判定部２４２は、簡易生体データが示す生体情報に異常があると判定した場合、その旨を要求部２４３に通知する。 The determination unit 242 determines whether or not there is an abnormality in the biometric information indicated by the simple biometric data included in the notification packet received by the data reception unit 241. The determination unit 242 is included in, for example, the first simple biometric data included in the broadcast packet received by the data receiving unit 241 and the broadcast packet transmitted in the past by the biometric information transmitting device 1 that transmitted the broadcast packet. The second simplified biometric data is compared, and if the difference between the first simplified biometric data and the second simplified biometric data is equal to or greater than the threshold value, it is determined that there is an abnormality. When the determination unit 242 determines that there is an abnormality in the biometric information indicated by the simple biometric data, the determination unit 242 notifies the request unit 243 to that effect.
　判定部２４２は、簡易生体データに生体情報送信装置１の加速度が含まれている場合、連続して送信された複数の簡易生体データに含まれる複数の加速度の差に基づいて、生体情報送信装置１を装着した被監視者Ｈの動きを特定することにより、被監視者Ｈの状態が正常であるか否かを判定してもよい。判定部２４２は、例えば、予め記憶部２３に記憶された加速度の変化のパターンと人の動きとの関係を示すテーブルを参照することにより、複数の加速度の間の変化に対応する被監視者Ｈの動きを特定する。 When the simple biometric data includes the acceleration of the biometric information transmitting device 1, the determination unit 242 uses the biometric information transmitting device based on the difference between the plurality of accelerations included in the plurality of continuously transmitted simple biometric data. By specifying the movement of the monitored person H wearing 1, it may be determined whether or not the state of the monitored person H is normal. The determination unit 242 refers to, for example, a table showing the relationship between the acceleration change pattern and the movement of a person stored in the storage unit 23 in advance, so that the monitored person H responds to the change between the plurality of accelerations. Identify the movement of.
　記憶部２３が、複数の加速度が測定された時間差ごとにテーブルを記憶しており、判定部２４２は、複数の簡易生体データを受信した時間差に対応するテーブルを参照することにより被監視者Ｈの動きを特定してもよい。判定部２４２がこのように動作することで、生体情報受信装置２の管理者が、例えば被監視者Ｈが転倒したことを速やかに把握することができる。 The storage unit 23 stores a table for each time difference in which a plurality of accelerations are measured, and the determination unit 242 refers to the table corresponding to the time difference in which the plurality of simple biometric data is received, so that the monitored person H can use the table. The movement may be specified. By operating the determination unit 242 in this way, the administrator of the biometric information receiving device 2 can quickly grasp, for example, that the monitored person H has fallen.
　判定部２４２は、第１簡易生体データを受信した時刻と第２簡易生体データを受信した時刻との差に対応する閾値に基づいて異常の有無を判定してもよい。判定部２４２は、例えば第１簡易生体データを受信した時刻と第２簡易生体データを受信した時刻との差が第１時間である場合に、差が第１時間よりも大きい第２時間である場合よりも閾値を小さくする。 The determination unit 242 may determine the presence or absence of an abnormality based on the threshold value corresponding to the difference between the time when the first simple biometric data is received and the time when the second simple biometric data is received. The determination unit 242 is, for example, a second time in which the difference is larger than the first time when the difference between the time when the first simple biometric data is received and the time when the second simple biometric data is received is the first time. Make the threshold smaller than in the case.
　判定部２４２がこのように動作することで、判定部２４２は、急な変化がある場合に、変化量が比較的小さい場合であっても異常であると検出することができる。また、判定部２４２は、長時間が経過して、周囲の環境（例えば温度又は湿度）が変化したことに伴う変化があった場合に異常であると検出しにくくすることができる。 By operating the determination unit 242 in this way, the determination unit 242 can detect that there is an abnormality even when the amount of change is relatively small when there is a sudden change. Further, the determination unit 242 can make it difficult to detect that it is abnormal when there is a change due to a change in the surrounding environment (for example, temperature or humidity) over a long period of time.
　要求部２４３は、判定部２４２が生体情報に異常があると判定した場合に、第１通信部２１に指示して、異常があると判定部２４２が判定した生体情報を含む報知パケットを送信した生体情報送信装置１とのコネクションを確立させる。そして、要求部２４３は、第１通信部２１を介して、当該生体情報に対応する生体データを送信した生体情報送信装置１に対して、簡易生体データよりも多くの情報を含む詳細生体データを要求するための要求パケットを生体情報送信装置に送信する。 When the determination unit 242 determines that the biometric information is abnormal, the request unit 243 instructs the first communication unit 21 to transmit a notification packet including the biometric information determined by the determination unit 242 to be abnormal. Establish a connection with the biological information transmitting device 1. Then, the requesting unit 243 transmits detailed biometric data including more information than the simple biometric data to the biometric information transmitting device 1 that has transmitted the biometric data corresponding to the biometric information via the first communication unit 21. A request packet for making a request is transmitted to the biometric information transmitter.
　具体的には、要求部２４３は、簡易生体データが示す複数の生体情報のうち、異常があると判定した生体情報に対する詳細データを要求するための要求パケットを生体情報送信装置１に送信する。要求部２４３は、例えば、簡易生体データが示す生体情報に基づいて血圧に異常があると判定部２４２が判定した場合、血圧の詳細生体データを生体情報送信装置１に要求する。このように、要求部２４３が、異常があると判定された生体情報の詳細生体データのみを要求することで、生体情報送信装置１の処理が重くなったり、通信チャネルが混雑したりすることを抑制できる。 Specifically, the requesting unit 243 transmits a request packet for requesting detailed data for the biometric information determined to be abnormal among the plurality of biometric information indicated by the simple biometric data to the biometric information transmitting device 1. For example, when the determination unit 242 determines that the blood pressure is abnormal based on the biometric information indicated by the simple biometric data, the requesting unit 243 requests the biometric information transmitting device 1 for detailed biometric data of the blood pressure. In this way, when the requesting unit 243 requests only the detailed biometric data of the biometric information determined to be abnormal, the processing of the biometric information transmitting device 1 becomes heavy and the communication channel becomes congested. Can be suppressed.
　要求部２４３は、簡易生体データが示す生体情報の変化率が閾値以上である場合に、詳細生体データを要求するための要求パケットを生体情報送信装置１に送信し、変化率が閾値未満である場合に要求パケットを生体情報送信装置１に送信しないようにしてもよい。閾値は、異常が発生している蓋然性が高いと考えられる変化率に基づいて定められている。要求部２４３がこのように動作することで、異常がある蓋然性が低い場合に要求部２４３が詳細生体データを要求することを抑制できる。 When the rate of change of biometric information indicated by the simplified biometric data is equal to or greater than the threshold value, the requesting unit 243 transmits a request packet for requesting detailed biometric data to the biometric information transmitting device 1, and the rate of change is less than the threshold value. In some cases, the request packet may not be transmitted to the biometric information transmission device 1. The threshold is set based on the rate of change that is considered to be highly probable that an abnormality has occurred. By operating the requesting unit 243 in this way, it is possible to suppress the requesting unit 243 from requesting detailed biometric data when the probability of abnormality is low.
［生体情報取得システムＳによる効果］
　以上説明したように、生体情報送信装置１は、生体情報取得部１４１が取得した生体情報に基づいて作成した簡易生体データを含み、簡易生体データの送信先が指定されていない報知パケットを所定の送信間隔で送信する。そして、生体情報受信装置２は、受信した報知パケットに含まれる簡易生体データが示す生体情報に異常があると判定した場合に、当該生体情報に対応する生体データを送信した生体情報送信装置１に対して、簡易生体データよりも多くの情報を含む詳細生体データを要求するための要求パケットを生体情報送信装置１に送信する。 [Effect of biometric information acquisition system S]
As described above, the biometric information transmission device 1 includes a simple biometric data created based on the biometric information acquired by the biometric information acquisition unit 141, and a predetermined notification packet in which the destination of the simple biometric data is not specified. Send at the transmission interval. Then, when the biometric information receiving device 2 determines that the biometric information indicated by the simple biometric data included in the received notification packet is abnormal, the biometric information receiving device 2 sends the biometric data corresponding to the biometric information to the biometric information transmitting device 1. On the other hand, a request packet for requesting detailed biometric data including more information than simple biometric data is transmitted to the biometric information transmitting device 1.
　生体情報送信装置１及び生体情報受信装置２がこのように動作することで、複数の生体情報送信装置１が生体情報受信装置２と通信する環境において、生体情報受信装置２が複数の生体情報送信装置１のそれぞれとの間でコネクションを確立することなく、生体情報受信装置２が被監視者Ｈの生体情報を定常的に取得することができる。そして、生体情報受信装置２が受信した生体情報に異常があると判定した場合に、詳細な生体情報を取得することができる。 By operating the biometric information transmitting device 1 and the biometric information receiving device 2 in this way, in an environment in which a plurality of biometric information transmitting devices 1 communicate with the biometric information receiving device 2, the biometric information receiving device 2 transmits a plurality of biometric information. The biometric information receiving device 2 can constantly acquire the biometric information of the monitored person H without establishing a connection with each of the devices 1. Then, when it is determined that the biometric information received by the biometric information receiving device 2 is abnormal, detailed biometric information can be acquired.
　したがって、生体情報受信装置２が、生体情報を送信する複数の生体情報送信装置１から、通信コネクションを確立することなく、定期的に生体情報を受信することにより、複数の被監視者Ｈの生体情報を、通信コネクションを確立する場合より短い時間間隔で監視することができる。その結果、生体情報を送信する対象となる人が多数いる施設において、管理者が生体情報取得システムＳを使用することにより、多数の人の生体情報をリアルタイムで監視しやすくなるとともに、生体情報の異常を把握しやすくなる。 Therefore, the biometric information receiving device 2 periodically receives the biometric information from the plurality of biometric information transmitting devices 1 that transmit the biometric information without establishing a communication connection, so that the living body of the plurality of monitored persons H Information can be monitored at shorter time intervals than when establishing a communication connection. As a result, in a facility where there are many people to whom the biometric information is transmitted, the administrator can easily monitor the biometric information of a large number of people in real time by using the biometric information acquisition system S, and the biometric information can be obtained. It becomes easier to grasp the abnormality.
