従来の通信機能を兼ね備えた生体情報測定装置２０２においては、個人情報である生体情報が電波により飛ばされるため、セキュリティ上の問題があった。また、生体情報測定装置を起動させるメインスイッチ２０３のほかに生体情報を測定するための生体センサを未装着状態で動作させていると電池の消耗が速いため、装着確認センサまたは生体情報測定可能時に生体センサに電力を供給するスイッチ２０１を別途設ける必要があった。また生体情報を送受信するためのアンテナ２０４を設ける必要があるため、小型化が困難であった。   The biometric information measuring apparatus 202 having a conventional communication function has a security problem because the biometric information, which is personal information, is skipped by radio waves. In addition to the main switch 203 that activates the biological information measuring device, if a biological sensor for measuring biological information is operated in an unattached state, the battery is consumed quickly. It was necessary to separately provide a switch 201 for supplying power to the biosensor. Further, since it is necessary to provide an antenna 204 for transmitting and receiving biological information, it is difficult to reduce the size.

電界通信において、生体と送受信機とが電気的に結合していることにより通信が可能となることから、他の送受信機と電界通信による通信が可能であれば、電界通信機能を有する生体情報測定装置が生体に装着されていると判断できることを本発明者は見出した。本発明は、この新たな知見により上記の課題解決を図るものであり、通信時のセキュリティ性が高く、なおかつ部品点数を増やさずに消費電力を低く抑えられる生体情報測定装置、および生体情報測定方法を提供することを目的とする。   In electric field communication, since a living body and a transmitter / receiver are electrically coupled to each other, communication is possible. Therefore, if communication with another transmitter / receiver is possible, biological information measurement having an electric field communication function is possible.

従来例の通信方式は無線通信であるため、生体情報測定装置と他の送受信機との間で無線通信が可能であったとしても、生体が通信機を装着しているとは限らず、別途生体情報測定装置が装着され、生体情報が測定可能であるか否かを判断する専用のセンサが必要となる。   Since the communication method of the conventional example is wireless communication, even if wireless communication is possible between the biological information measuring device and another transceiver, the biological body is not necessarily equipped with a communication device, A biometric information measurement device is attached, and a dedicated sensor for determining whether or not biometric information can be measured is required.

それに対して本実施例の通信方式は電界通信であり、生体情報測定装置と他の送受信機との間で電界通信が可能であれば、生体が生体情報測定装置と他の送受信機とを装着している可能性が高いと判定できる。つまり通信状態と生体情報測定装置装着有無との間に相関があるため、通信が可能であることが生体情報測定装置を装着していることになり、生体情報測定装置装着有無を判断する専用のセンサが必要ないため、部品点数が削減できる。   On the other hand, the communication method of the present embodiment is electric field communication, and if the electric field communication is possible between the biological information measuring device and another transceiver, the living body wears the biological information measuring device and the other transceiver. It can be determined that there is a high possibility that In other words, since there is a correlation between the communication state and the presence or absence of the biological information measuring device, it means that the communication is possible and the biological information measuring device is attached. Since no sensor is required, the number of parts can be reduced.

図３は、本実施例の生体センサ１４に好適に用いられる光電式脈波センサの構成図の例である。   FIG. 3 is an example of a configuration diagram of a photoelectric pulse wave sensor preferably used for the biological sensor 14 of the present embodiment.

光電式脈波センサ１４は、発光素子５２と受光素子５４と増幅回路５６と前記発光素子の光強度を調整する調整部５３から構成されている。光電式脈波センサ１４は、発光素子５２から血管に向けて発光し、血管を通った光を受光素子５４で受光し、受光素子５４で受光した光強度の変化を検出することで血管の収縮を把握し、それにより脈波を検出する。   The photoelectric pulse wave sensor 14 includes a light emitting element 52, a light receiving element 54, an amplifier circuit 56, and an adjusting unit 53 that adjusts the light intensity of the light emitting element. The photoelectric pulse wave sensor 14 emits light from the light emitting element 52 toward the blood vessel, the light passing through the blood vessel is received by the light receiving element 54, and the change of the light intensity received by the light receiving element 54 is detected, thereby contracting the blood vessel. To detect the pulse wave.

発光素子５２を用いる光電式脈波センサ１４では、発光時に電界通信時に比べて約１０倍の電力を消費するため、生体情報測定可能時にのみ発光素子５２に電力供給を行うことで、低消費電力化が効果的に実現できた。   Since the photoelectric pulse wave sensor 14 using the light emitting element 52 consumes about 10 times the electric power during light emission as compared with that during electric field communication, power is supplied to the light emitting element 52 only when biometric information can be measured. Could be realized effectively.

図４に、光電式脈波センサ１４の発光素子５２の光強度を徐々に増し、脈波波形を検出したグラフの一例を示す。グラフの横軸が時間、左縦軸が脈波センサ１４の出力電圧、右縦軸が発光素子５２への印加電圧である。図５により、脈波センサ１４の脈波測定時の出力電圧が、脈波センサ１４の最大出力電圧(１．６mV)の８０％程度になるまで発光素子５２への印加電圧を徐々に増やすことで、脈波センサ１４の脈波測定時の脈波出力が徐々に増大し、出力が飽和することなく、かつ振幅が十分に大きくでき、精度よく脈波が検出されていることがわかる。   FIG. 4 shows an example of a graph in which the light intensity of the light emitting element 52 of the photoelectric pulse wave sensor 14 is gradually increased to detect the pulse wave waveform. In the graph, the horizontal axis represents time, the left vertical axis represents the output voltage of the pulse wave sensor 14, and the right vertical axis represents the voltage applied to the light emitting element 52. According to FIG. 5, the voltage applied to the light emitting element 52 is gradually increased until the output voltage at the time of pulse wave measurement of the pulse wave sensor 14 becomes about 80% of the maximum output voltage (1.6 mV) of the pulse wave sensor 14. Thus, it can be seen that the pulse wave output at the time of pulse wave measurement of the pulse wave sensor 14 gradually increases, the output is not saturated, the amplitude can be sufficiently increased, and the pulse wave is detected with high accuracy.

本発明の第２の実施の形態に係る電界通信機能付き生体情報測定ユニットの説明を、図１を用いて行う。   A biological information measuring unit with an electric field communication function according to a second embodiment of the present invention will be described with reference to FIG.

第２の実施の形態は、第１の実施の形態に対し、他の送受信機５０が生体情報処理装置３である点が異なる。生体センサ１４で測定された生体情報は、通信部１５に送られ、電極４および生体１を介して、電極９を有する生体情報処理装置３へ送られる。   The second embodiment is different from the first embodiment in that another transceiver 50 is the biological information processing apparatus 3. The biological information measured by the biological sensor 14 is sent to the communication unit 15, and is sent to the biological information processing apparatus 3 having the electrode 9 via the electrode 4 and the living body 1.

生体情報処理装置３は、電界通信のための電極９、電極１０、生体情報測定装置２との通信可否を判定するために必要な通信信号を送受信できる信号送受信部２１、生体情報測定装置２との通信が可能なとき生体情報測定装置２からの生体情報を収集するための生体情報収集部２２、および生体情報などの通信信号を表示する表示部１２、通信信号を記録する記録部１３を具備している。生体情報測定装置２から送られてきた生体情報は、電極９を介して信号送受信部２１に送られる。信号送受信部２１は通信信号から脈波などの生体情報や個体識別番号などを検出した後に、生体情報収集部２２に生体情報や個体識別番号などを送る。生体情報収集部２２は送られてきた生体情報や個体識別番号などを、表示部１２に表示させ、また記録部１３に記録させる。   The biological information processing device 3 includes a signal transmission / reception unit 21 that can transmit and receive a communication signal necessary for determining whether or not communication with the electrode 9 and the electrode 10 for electric field communication and the biological information measurement device 2 is possible, and the biological information measurement device 2 A biological information collection unit 22 for collecting biological information from the biological information measuring device 2 when communication is possible, a display unit 12 for displaying a communication signal such as biological information, and a recording unit 13 for recording the communication signal. doing. The biological information sent from the biological information measuring device 2 is sent to the signal transmission / reception unit 21 via the electrode 9. The signal transmission / reception unit 21 detects biological information such as a pulse wave and an individual identification number from the communication signal, and then transmits the biological information and the individual identification number to the biological information collection unit 22. The biometric information collecting unit 22 displays the sent biometric information, individual identification number, and the like on the display unit 12 and records them in the recording unit 13.

本発明の第２の実施の形態に係る電界通信機能付き生体情報測定ユニットに特有な制御方式の例について、図５に従って説明する。   An example of a control method unique to the biological information measuring unit with electric field communication function according to the second embodiment of the present invention will be described with reference to FIG.

本発明の電界通信機能付き生体情報測定ユニットにおいては、生体情報処理装置３より、通信の可否を判定するための通信確認信号を送信Ｓ１する。   In the biological information measuring unit with electric field communication function of the present invention, the biological information processing apparatus 3 transmits S1 a communication confirmation signal for determining whether communication is possible.

生体情報測定装置２においては、前記通信確認信号により、通信可否を判定Ｓ２し、通信可と判定した時には、脈波センサを駆動するための電力を供給Ｓ３する。続いて、脈波センサの発光素子の発光を開始Ｓ４し、脈波センサの出力を確認Ｓ５する。その後、脈波出力を確認しながら、発光素子の光強度を調整Ｓ６し、得られた脈波情報を生体情報測定装置より送信Ｓ７する。   The biological information measuring apparatus 2 determines whether or not communication is possible based on the communication confirmation signal, and supplies power for driving the pulse wave sensor when it is determined that communication is possible. Subsequently, the light emission of the light emitting element of the pulse wave sensor is started S4, and the output of the pulse wave sensor is confirmed S5. Then, while confirming the pulse wave output, the light intensity of the light emitting element is adjusted S6, and the obtained pulse wave information is transmitted S7 from the biological information measuring device.

送信された脈波情報は、生体情報処理装置３にて受信Ｓ８され、脈波情報の表示および記録Ｓ９が行われる。また、測定された脈波情報は、病院などの情報センタに送信Ｓ１０される。   The transmitted pulse wave information is received S8 by the biological information processing apparatus 3, and the pulse wave information is displayed and recorded S9. Further, the measured pulse wave information is transmitted S10 to an information center such as a hospital.

図６は、本発明の第３の実施の形態に係る、複数の生体情報測定装置を有する電界通信機能付き生体情報測定ユニットの構成図の一例である。本実施の形態は、第2の実施の形態に対し、異種の生体情報を測定する生体センサ１４を有する生体情報測定装置２が複数ある点が異なる。生体である人体１０１に、脈波センサ１０２を有する第１の生体情報測定装置、体温センサ１０３を有する第２の生体情報測定装置、呼吸センサ１０４を有する第３の生体情報測定装置、および加速度センサ１０５を有する第４の生体情報測定装置が、例えば手首、首、足首などに装着されている。また、各生体情報測定装置１０２、１０３、１０４，１０５で取得した生体情報を受信、表示、および記録するための生体情報処理装置１０６が、例えば腰付近に装着されている。   FIG. 6 is an example of a configuration diagram of a biological information measuring unit with an electric field communication function having a plurality of biological information measuring devices according to the third embodiment of the present invention. This embodiment is different from the second embodiment in that there are a plurality of biological information measuring devices 2 each having a biological sensor 14 that measures different types of biological information. A first biological information measuring device having a pulse wave sensor 102 on a human body 101 that is a living body, a second biological information measuring device having a body temperature sensor 103, a third biological information measuring device having a respiratory sensor 104, and an acceleration sensor A fourth biological information measuring apparatus having 105 is attached to, for example, a wrist, a neck, an ankle and the like. In addition, a biological information processing apparatus 106 for receiving, displaying, and recording the biological information acquired by each of the biological information measuring apparatuses 102, 103, 104, and 105 is mounted near the waist, for example.

脈波センサ１０２、体温センサ１０３、呼吸センサ１０４および加速度センサ１０５で取得された生体情報は、生体情報処理装置１０６に送られる。生体情報処理装置１０６は、送られた生体情報から、表示部１２に生体情報等を表示させ、また記録部１３に生体情報等を記録させる。   The biological information acquired by the pulse wave sensor 102, the body temperature sensor 103, the respiration sensor 104, and the acceleration sensor 105 is sent to the biological information processing apparatus 106. The biological information processing apparatus 106 causes the display unit 12 to display biological information or the like from the sent biological information, and causes the recording unit 13 to record the biological information or the like.

生体情報処理装置１０６は、人体１０１と容量結合していればよく、必ずしも人体１０１に装着されている必要はない。生体情報処理装置１０６は、例えば人体１０１が接触する自転車やランニングマシンなどの運動・健康機器に装備されている。この場合、電極９は、ハンドルや取手に設置されている。   The biological information processing apparatus 106 is only required to be capacitively coupled to the human body 101 and is not necessarily attached to the human body 101. The biological information processing apparatus 106 is equipped, for example, in exercise / health equipment such as a bicycle or a running machine with which the human body 101 comes into contact. In this case, the electrode 9 is installed on a handle or a handle.


図７は、本発明の第４の実施の形態に係る、同種の生体情報を測定する生体センサ１４を有する生体情報測定装置２を複数個有する電界通信機能付き生体情報測定ユニットの構成図の一例である。本実施の形態は、第３の実施の形態に対し、生体センサ１４が同種の生体情報を測定するものである点が異なる。人体１０１に第１の脈波センサ１０２Ａ、第２の脈波センサ１０２Ｂ、および第３の脈波センサ１０２Ｃが例えば手首、首、足首などに装着されている。また、各生体情報測定装置で取得した生体情報を表示および記録するための生体情報処理装置１０６が、例えば腰付近に装着されている。
FIG. 7 is an example of a configuration diagram of a biological information measuring unit with an electric field communication function having a plurality of biological information measuring devices 2 having biological sensors 14 for measuring the same type of biological information according to the fourth embodiment of the present invention. It is. This embodiment is different from the third embodiment in that the biological sensor 14 measures the same kind of biological information. A first pulse wave sensor 102A, a second pulse wave sensor 102B, and a third pulse wave sensor 102C are attached to the human body 101, for example, on the wrist, neck, ankle, or the like. In addition, a biological information processing device 106 for displaying and recording biological information acquired by each biological information measuring device is attached, for example, near the waist.

第１、第２、第３および第４の脈波センサ１０２Ａ，１０２Ｂ，および１０２Ｃで取得された生体情報は、生体情報処理装置１０６の生体情報収集部２２を通して生体情報判定部３１に送られる。生体情報判定部３１は、送られた生体情報のうち、体動影響などのノイズにより生体情報として活用できないデータがあるかどうか判定する。生体情報判定部３１は、活用できないと判定したデータは表示・記録せず、生体情報として有用な出力である信号のみを表示・記録する。   The biological information acquired by the first, second, third, and fourth pulse wave sensors 102A, 102B, and 102C is sent to the biological information determination unit 31 through the biological information collection unit 22 of the biological information processing device 106. The biological information determination unit 31 determines whether there is data that cannot be used as biological information due to noise such as the influence of body movement in the transmitted biological information. The biological information determination unit 31 does not display / record data determined to be unusable, but displays / records only signals that are useful output as biological information.

生体情報処理装置１０６は、人体１０１と容量結合していればよく、必ずしも人体１０１に装着されている必要はない。生体情報処理装置１０６は、例えば人体１０１が接触する自転車やランニングマシンなどの運動・健康機器に装備されている。この場合、電極９は、ハンドルや取手に設置されている。   The biological information processing apparatus 106 is only required to be capacitively coupled to the human body 101 and is not necessarily attached to the human body 101. The biological information processing apparatus 106 is equipped, for example, in exercise / health equipment such as a bicycle or a running machine with which the human body 101 comes into contact. In this case, the electrode 9 is installed on a handle or a handle.

図８のＡ１、Ｂ１、およびＣ１は、本発明の第４の実施の形態に係る第１、第２、および第３の脈波センサ１０２Ａ，１０２Ｂ，および１０２Ｃの脈波出力を示したグラフの一例である。また、図８のＡ２、Ｂ２、およびＣ２は、脈派出力グラフ図８のＡ１、Ｂ１、およびＣ１を、時間で１回微分したグラフの一例である。   A1, B1, and C1 in FIG. 8 are graphs showing pulse wave outputs of the first, second, and third pulse wave sensors 102A, 102B, and 102C according to the fourth embodiment of the present invention. It is an example. Further, A2, B2, and C2 in FIG. 8 are examples of a graph obtained by differentiating A1, B1, and C1 in FIG. 8 once with respect to time.

図８のＡ１は脈波出力電圧が小さい場合、図８のＢ１は脈波出力電圧が適度な場合、図８のＣ１は脈波出力電圧が大きい場合である。   A1 in FIG. 8 is when the pulse wave output voltage is small, B1 in FIG. 8 is when the pulse wave output voltage is moderate, and C1 in FIG. 8 is when the pulse wave output voltage is large.

出力が良好なデータとは、脈波センサ出力電圧を時間で一回微分したグラフ図８のＡ２、Ｂ２、およびＣ２で０（ゼロ）クロスの点を検出して、その点の時間間隔から心拍数を算出し、心拍数が一定の範囲（例えば１０〜２００ｂｐｍの範囲）に入っていることを指す。   Data with good output is a graph obtained by differentiating the pulse wave sensor output voltage once in time. A point of 0 (zero) cross is detected at A2, B2, and C2 in FIG. The number is calculated to indicate that the heart rate is within a certain range (for example, a range of 10 to 200 bpm).

図８のＡ１、およびＡ２では、脈波出力グラフ図８のＡ１および1回微分グラフ図８のＡ２とも振幅が小さく、脈波検出が困難である。また、図８のＣ１、およびＣ２においては、脈波出力グラフ図８のＣ１がアンプの出力の上限値に達しており、１回微分グラフ図８のＣ２では大半の時間の微分値が０となるため、脈波検出が困難である。一方、図８のＢ１、およびＢ２においては、脈波出力グラフ図８のＢ１がアンプ出力の上限以下で大きな振幅も得られ、1回微分のグラフ図８のＢ２の０クロスの点が規則的に検出されているため、脈波検出が精度よく行われている。   In A1 and A2 of FIG. 8, the amplitude of the pulse wave output graph A1 of FIG. 8 and A2 of the first derivative graph of FIG. 8 is small, and it is difficult to detect the pulse wave. Further, in C1 and C2 of FIG. 8, pulse wave output graph C1 of FIG. 8 has reached the upper limit value of the output of the amplifier, and in the differential graph of FIG. Therefore, pulse wave detection is difficult. On the other hand, in B1 and B2 of FIG. 8, a large amplitude is obtained when B1 of the pulse wave output graph of FIG. 8 is less than or equal to the upper limit of the amplifier output, and the zero cross point of B2 of FIG. Therefore, the pulse wave is detected with high accuracy.

本発明の第５の実施の形態に係る、生体情報を記録する記録部を有する電界通信機能付き生体情報測定ユニットの構成図の例および特有な制御方式の例について、図９および図１０を用いて説明する。本実施の形態と第３の実施の形態との違いは、生体情報測定装置２が生体１に装着された生体情報処理装置３との通信が可能と判断しなかった場合、他の生体情報測定装置２と通信可能であるか否かを判定する通信判定部１６を有していること、および測定した生体情報を記録するための記録部４１を有していることである。   FIG. 9 and FIG. 10 are used for an example of a configuration diagram of a biological information measuring unit with an electric field communication function having a recording unit for recording biological information and an example of a specific control method according to the fifth embodiment of the present invention. I will explain. The difference between the present embodiment and the third embodiment is that when the biological information measuring device 2 does not determine that communication with the biological information processing device 3 attached to the living body 1 is possible, another biological information measurement is performed. It has the communication determination part 16 which determines whether it can communicate with the apparatus 2, and has the recording part 41 for recording the measured biometric information.

第３の実施の形態で、生体情報測定装置２ａにおいて、前記通信確認信号により通信可否を判定Ｓ２し、通信可能と判定できなかった場合、他の生体情報測定装置２ｂから発信されている通信可否を判定するために必要な通信信号を検索する。通信判定部１６が、生体情報測定装置２ａと他の生体情報測定装置２ｂとが通信可能と判定した場合、生体１が生体情報測定装置２ａと他の生体情報測定装置２ｂとを装着しており生体情報を測定可能な環境にあると見做し、通信可能という情報を生体情報測定装置２ａの制御部１７ａに送る。制御部１７ａは、生体情報測定装置２ａの生体センサ１４ａに電力供給し生体情報測定を開始させる。生体センサ１４ａで測定された生体情報は、生体情報測定装置２ａの記録部４１ａに記録される。他の生体情報測定装置２ｂも同様に、通信可能という情報を生体情報測定装置２ｂの制御部１７ｂに送る。制御部１７ｂは、生体情報測定装置２ｂの生体センサ１４ｂに電力供給し生体情報測定を開始させる。生体センサ１４ｂで測定された生体情報は、生体情報測定装置２ｂの記録部４１ｂに記録される。   In the third embodiment, the biological information measuring device 2a determines whether communication is possible based on the communication confirmation signal, and if it cannot be determined that communication is possible, the communication availability transmitted from another biological information measuring device 2b. A communication signal necessary for determining the communication is searched. When the communication determination unit 16 determines that the biological information measuring device 2a and the other biological information measuring device 2b can communicate with each other, the living body 1 wears the biological information measuring device 2a and the other biological information measuring device 2b. Assuming that there is an environment in which biological information can be measured, information indicating that communication is possible is sent to the control unit 17a of the biological information measuring device 2a. The control unit 17a supplies power to the biological sensor 14a of the biological information measuring device 2a to start measuring biological information. The biological information measured by the biological sensor 14a is recorded in the recording unit 41a of the biological information measuring device 2a. Similarly, the other biological information measuring device 2b sends information that communication is possible to the control unit 17b of the biological information measuring device 2b. The control unit 17b supplies power to the biological sensor 14b of the biological information measuring device 2b to start the biological information measurement. The biological information measured by the biological sensor 14b is recorded in the recording unit 41b of the biological information measuring device 2b.

また、図９の第５の実施の形態において、生体情報測定装置２ａと他の生体情報測定装置２ｂに加えて、生体情報測定中ないし測定後に生体情報処理装置３が生体１に装着されて、生体情報測定装置２ａと生体情報処理装置３との電界通信が可能と判定された場合、生体情報測定装置２ａは、記録部４１ａに記録された生体情報を、生体情報処理装置３に送信する。   In addition, in the fifth embodiment of FIG. 9, in addition to the biological information measuring device 2a and the other biological information measuring device 2b, the biological information processing device 3 is attached to the living body 1 during or after the biological information measurement, When it is determined that the electric field communication between the biological information measuring device 2a and the biological information processing device 3 is possible, the biological information measuring device 2a transmits the biological information recorded in the recording unit 41a to the biological information processing device 3.

生体情報処理装置３の信号送受信部２１は、送信された通信信号から脈波などの生体情報や個体識別番号などを検出した後に、生体情報収集部２２に生体情報や個体識別番号などを送る。生体情報収集部２２は送られてきた生体情報や個体識別番号などを、表示部１２に生体情報等を表示させ、また記録部１３に生体情報等を記録させる。   The signal transmitting / receiving unit 21 of the biological information processing apparatus 3 detects the biological information such as a pulse wave and the individual identification number from the transmitted communication signal, and then transmits the biological information, the individual identification number, and the like to the biological information collecting unit 22. The biometric information collection unit 22 displays the biometric information and the individual identification number sent thereto on the display unit 12, and causes the recording unit 13 to record the biometric information and the like.

本発明は上記実施の形態に限定されず、本発明の目的の範囲を逸脱しない限りにおいて適宜変更することが可能である。   The present invention is not limited to the above-described embodiment, and can be modified as appropriate without departing from the scope of the object of the present invention.
