（参考形態１）
この参考形態は、睡眠検知による防犯装置を一般住宅に適用したものである。この睡眠検知による防犯装置は、図１に示されるように生体信号検出手段１０と、睡眠状態判定手段２０と、制御手段６０と、住宅防犯手段３０とを備えている。この防犯装置は、ベット４０のマットレス４１上に寝る就寝者の人体５０の生体信号を検出するとともに、この生体信号からこの就寝者の睡眠状態を判定し、その判定に基づいて住宅防犯手段３０の作動を制御するものである。 ( Reference form 1)
In this reference form , a security device based on sleep detection is applied to a general house. As shown in FIG. 1, the crime prevention device by sleep detection includes a biological signal detection unit 10, a sleep state determination unit 20, a control unit 60, and a home crime prevention unit 30. This crime prevention device detects a biological signal of the sleeper's human body 50 sleeping on the mattress 41 of the bed 40, determines the sleep state of the sleeper from the biological signal, and based on the determination, the home security means 30. It controls the operation.

生体信号検出手段１０は、図２に示されるように、発光素子２及び受光素子３を有する周知の反射光学式の検出部１と、発光素子３を駆動する駆動回路４と、受光素子の信号を検出する検出回路５と、検出回路５で検出した信号を解析するデータ解析部６とを備えた脈波センサにより構成されている。なお、検出部１は検出窓１１を有し、この検出窓１１を人体５０の腕５１等に接触させた状態で、図示しないベルト等により人体５０に取り付けられて使用される。   As shown in FIG. 2, the biological signal detection unit 10 includes a well-known reflective optical detection unit 1 having a light emitting element 2 and a light receiving element 3, a drive circuit 4 for driving the light emitting element 3, and a signal from the light receiving element. It is comprised by the pulse wave sensor provided with the detection circuit 5 which detects this, and the data analysis part 6 which analyzes the signal detected by the detection circuit 5. FIG. The detection unit 1 has a detection window 11 and is used by being attached to the human body 50 with a belt or the like (not shown) in a state where the detection window 11 is in contact with the arm 51 of the human body 50 or the like.

睡眠状態判定手段２０は、生体信号検出手段（脈波センサ）１０の出力信号から就寝者の睡眠状態を判定するデータ解析装置であり、生体信号検出手段１０の出力信号の周波変化を解析し、図４に示されるような就寝者の睡眠段階（睡眠状態）を示す線図に変換する。この図４の睡眠段階を示す線図によれば、就寝者の入眠時と目覚め時を特定することができ、したがってこの入眠時と目覚め時との間を睡眠中と判定することができる。この睡眠状態判定手段２０は、就寝者の入眠を検知した時は入眠検知信号を制御手段６０へ送り、また、就寝者の目覚めを検知した時は目覚め検知信号を制御手段６０へ送る。   The sleep state determination unit 20 is a data analysis device that determines the sleep state of the sleeping person from the output signal of the biological signal detection unit (pulse wave sensor) 10, analyzes the frequency change of the output signal of the biological signal detection unit 10, It converts into the diagram which shows the sleep stage (sleep state) of a sleeper as shown in FIG. According to the diagram showing the sleep stage in FIG. 4, it is possible to specify the sleeping time and the awakening time of the sleeper, and therefore, it is possible to determine that the sleeping time is between the sleeping time and the awakening time. The sleep state determination means 20 sends a sleep detection signal to the control means 60 when the sleeper's sleep is detected, and sends a sleep detection signal to the control means 60 when the sleeper's awakening is detected.

住宅防犯手段３０は、玄関電気錠と、窓電気錠と、車庫や門等を開閉する電動シャッタと、人の侵入を検知する侵入検知装置と、侵入検知装置の検知信号に基づき警報を発する警報装置とから構成されている。   The home crime prevention means 30 includes an entrance electric lock, a window electric lock, an electric shutter that opens and closes a garage, a gate, and the like, an intrusion detection device that detects intrusion of a person, and an alarm that issues an alarm based on a detection signal of the intrusion detection device. Device.

制御手段６０は、睡眠状態判定手段２０からの出力信号に基づき、住宅防犯手段３０の作動を制御するもので、睡眠状態判定手段２０が就寝者の睡眠中を判定した場合は、玄関電気錠及び窓電気錠を施錠し、電動シャッタを閉鎖し、かつ、侵入検知装置及び警報装置をＯＮ状態としうるように構成されている。具体的には、睡眠状態判定手段２０から就寝者の入眠検知信号が送られてきたときは、制御手段６０は、その信号に応じて、玄関電気錠及び窓電気錠を施錠し、電動シャッタを閉鎖し、かつ、侵入検知装置及び警報装置をＯＮ状態とするように構成されている。一方、睡眠状態判定手段２０から就寝者の目覚め検知信号が送られてきたときは、制御手段６０は、その信号に応じて、玄関電気錠及び窓電気錠の施錠を解除し、電動シャッタを開放し、かつ、侵入検知装置及び警報装置をオフ状態とする。   The control unit 60 controls the operation of the home crime prevention unit 30 based on the output signal from the sleep state determination unit 20, and when the sleep state determination unit 20 determines that the sleeping person is sleeping, The window electric lock is locked, the electric shutter is closed, and the intrusion detection device and the alarm device can be turned on. Specifically, when a sleeper sleep detection signal is sent from the sleep state determination unit 20, the control unit 60 locks the entrance electric lock and the window electric lock in accordance with the signal, and the electric shutter. The intrusion detection device and the alarm device are closed and closed. On the other hand, when a sleeper awakening detection signal is sent from the sleep state determination means 20, the control means 60 releases the lock of the entrance electric lock and the window electric lock and opens the electric shutter according to the signal. In addition, the intrusion detection device and the alarm device are turned off.

このように構成された睡眠検知による防犯装置の作用について、以下説明する。   The operation of the crime prevention device based on sleep detection configured as described above will be described below.

まず、生体信号検出手段１０としての脈波センサの作用から説明する。検出部１の発光素子２から人体５０に向かって光が照射されると、その光の一部が人体５０の内部を通る毛細動脈５２に当たって毛細動脈５２内を流れる血液中のヘモグロビンに吸収される一方、残りの光が毛細動脈５２で反射して散乱し、散乱した光の一部が受光素子３に入射する。このとき、血液の脈動により毛細動脈５２にあるヘモグロビンの量が波動的に変化するので、ヘモグロビンに吸収される光の量も波動的に変化する。その結果、毛細動脈５２で反射して受光素子３で検出される受光量が変化する。この受光素子３における受光量の変化が、検出回路５を通して脈波情報（例えば、電圧信号）としてデータ解析部６に出力される。そして、データ解析部６は、図３に示されるように、脈波から脈拍間隔を検出し、下記（１）式に従って、脈拍間隔から脈拍数を算出する。   First, the operation of the pulse wave sensor as the biological signal detection means 10 will be described. When light is emitted from the light emitting element 2 of the detection unit 1 toward the human body 50, a part of the light hits the capillary artery 52 passing through the inside of the human body 50 and is absorbed by hemoglobin in the blood flowing in the capillary artery 52. On the other hand, the remaining light is reflected and scattered by the capillary artery 52, and a part of the scattered light enters the light receiving element 3. At this time, since the amount of hemoglobin in the capillary artery 52 changes in a wave manner due to blood pulsation, the amount of light absorbed in the hemoglobin also changes in a wave manner. As a result, the amount of light received reflected by the capillary artery 52 and detected by the light receiving element 3 changes. The change in the amount of light received by the light receiving element 3 is output to the data analysis unit 6 as pulse wave information (for example, a voltage signal) through the detection circuit 5. Then, as shown in FIG. 3, the data analysis unit 6 detects the pulse interval from the pulse wave, and calculates the pulse rate from the pulse interval according to the following equation (1).

脈拍数（回／分）＝６０×｛１／脈拍間隔（秒）｝ …（１）
この脈拍数に係る信号は生体信号検出手段１０から睡眠状態判定手段２０へ送られる。この生体信号検出手段１０からの出力信号は、その信号の周期変化が解析されて図４に示されるような睡眠状態線図に変換される。そして、この睡眠状態線図により、就寝者の入眠時及び目覚め時を特定し、この入眠時と目覚め時との間を睡眠中と判定することができる。すなわち、この睡眠状態判定手段２０は、就寝者の入眠時及び目覚め時をそれぞれ検知することができ、この入眠検知信号及び目覚め検知信号を制御手段６０へ送る。 Pulse rate (times / minute) = 60 × {1 / pulse interval (seconds)} (1)
The signal related to the pulse rate is sent from the biological signal detection means 10 to the sleep state determination means 20. The output signal from the biological signal detection means 10 is converted into a sleep state diagram as shown in FIG. And this sleep state diagram can identify the sleeping time and awakening time of the sleeping person, and can determine that the sleeping time is between the sleeping time and the awakening time. That is, the sleep state determination unit 20 can detect when the sleeper is asleep and wakes up, and sends the sleep detection signal and the wakeup detection signal to the control unit 60.

睡眠状態判定手段２０から入眠検知信号が制御手段６０に送られると、制御手段６０は住宅防犯手段３０を作動させる。すなわち、制御手段６０は、玄関電気錠及び窓電気錠を施錠し、電動シャッタを閉鎖し、かつ、侵入検知装置及び警報装置をオン状態とする。   When the sleep detection signal is sent from the sleep state determination means 20 to the control means 60, the control means 60 activates the house crime prevention means 30. That is, the control means 60 locks the door electric lock and the window electric lock, closes the electric shutter, and turns on the intrusion detection device and the alarm device.

こうして就寝者が入眠すると同時に、住宅防犯手段３０の各種防犯機能が働くため、就寝者は安心して睡眠することができる。また、就寝者がたとえ玄関電気錠等をかけ忘れて就寝したとしても、睡眠中は必ず施錠されるため、確実に住宅防犯機能を働かせることができる。   In this way, the sleeping person goes to sleep at the same time, and the various crime prevention functions of the house crime prevention means 30 work, so the sleeping person can sleep with peace of mind. Moreover, even if the sleeping person forgets to put on the entrance electric lock etc. and goes to sleep, the house crime prevention function can be surely activated because the sleeping person is always locked.

一方、睡眠状態判定手段２０から目覚め検知信号が制御手段６０に送られると、制御手段６０は、玄関電気錠及び窓電気錠を施錠し、電動シャッタを閉鎖し、かつ、侵入検知装置及び警報装置をオフ状態とする。   On the other hand, when a wake-up detection signal is sent from the sleep state determination unit 20 to the control unit 60, the control unit 60 locks the entrance electric lock and the window electric lock, closes the electric shutter, and detects the intrusion detection device and the alarm device. Is turned off.

なお、睡眠状態判定手段２０から就寝者の目覚め検知信号が送られてきたときは、玄関電気錠及び窓電気錠の施錠解除、電動シャッタの開放、並びに侵入検知装置及び警報装置のオフ制御のうちの一部のみが作動するようにしてもよい。 In addition, when a sleeper awakening detection signal is sent from the sleep state determination means 20, unlocking of the entrance electric lock and window electric lock, opening of the electric shutter, and off control of the intrusion detection device and the alarm device are included. Only a part of may be activated .

（参考形態２）
この参考形態は、防犯装置が設置される住宅に居住者が複数いる場合に対応させたもので、居住者全員が睡眠中のときのみに前記住宅防犯手段３０が働くようにしたものである。 ( Reference form 2)
This reference form corresponds to the case where there are a plurality of residents in the house where the security device is installed, and the home security means 30 works only when all the residents are sleeping.

すなわち、この睡眠検知による防犯装置は、複数（居住者の数に対応する数）の前記生体信号検出手段１０を有するとともに、各生体信号検出手段１０にそれぞれ対応する複数の前記睡眠状態判定手段２０を有している。そして、各睡眠状態判定手段２０からの出力信号は前記制御手段６０に送られるようになっている。   In other words, the crime prevention device based on sleep detection includes a plurality (the number corresponding to the number of residents) of the biological signal detection means 10 and a plurality of the sleep state determination means 20 respectively corresponding to the biological signal detection means 10. have. And the output signal from each sleep state determination means 20 is sent to the control means 60.

制御手段６０は、各睡眠状態判定手段２０の全てが居住者の睡眠中を判定したときのみに、前記住宅防犯手段３０を作動させて、玄関電気錠及び窓電気錠を施錠し、電動シャッタを閉鎖し、かつ、侵入検知装置及び警報装置をオン状態とするように構成されている。   The control means 60 activates the home crime prevention means 30 only when all of the sleep state determination means 20 determine that the resident is sleeping, and locks the entrance electric lock and the window electric lock, and the electric shutter. It is configured to close and to turn on the intrusion detection device and the alarm device.

したがって、この参考形態の睡眠検知による防犯装置によれば、居住者全員が睡眠中のときのみに前記住宅防犯手段３０が働くことになるため、居住者のうちの誰か一人が寝た後であっても、未だ起きている居住者や未だ帰宅していない居住者が、例えばこの家の出入りをする際に玄関の鍵が閉まっていたり、警報が鳴ったりするような不都合がない。 Therefore, according to the crime prevention apparatus based on sleep detection of this reference form, since the residential crime prevention means 30 works only when all the residents are sleeping, there is no one after one of the residents sleeps. However, there is no inconvenience that a resident who is still awake or a resident who has not returned home, for example, has his door locked or an alarm sounded when entering or leaving the house.

その他の構成及び作用効果は前記参考形態１と同様である。 Other configurations and operational effects are the same as the reference embodiment 1.

（実施形態）
この実施形態は、前記参考形態２において、居住者のうちの少なくとも一人が帰宅しない場合に、帰宅しない人を一時的に居住者でないものとみなしてその居住者の睡眠判定を一時的にキャンセルできるようにしたものである。 (Embodiment)
This embodiment, wherein the reference embodiment 2, when at least one person of residents can not go home, can be temporarily canceled sleep determination of its occupants and deemed not temporarily residents who do not go home It is what I did.

すなわち、この入眠検知による防犯装置は、複数の居住者にそれぞれが対応する複数の前記生体信号発生手段１０及び前記睡眠状態判定手段２０を有している。各睡眠状態判定手段２０と制御手段６０とをそれぞれ電気的に接続する各接続手段は、接続状態と切断状態とが切り換え可能となっている。そして、制御手段６０は、接続が切断された睡眠状態判定手段２０は無いものとして（この睡眠状態判定手段２０からの出力信号を待つことな
く）、前記参考形態２と同様の制御が行われるように構成されている。すなわち、制御手段６０は、睡眠状態判定手段２０のうちキャンセルされた少なくとも一つについての睡眠判定が行われない場合であっても、他の睡眠状態判定手段２０の判定に基づいて住宅防犯手段３０の作動を制御しうるように構成されている。 That is, the crime prevention apparatus based on sleep detection includes a plurality of the biological signal generation means 10 and the sleep state determination means 20 that respectively correspond to a plurality of residents. Each connection means that electrically connects each sleep state determination means 20 and the control means 60 can be switched between a connected state and a disconnected state. Then, the control unit 60 assumes that there is no sleep state determination unit 20 that has been disconnected (without waiting for an output signal from the sleep state determination unit 20), so that the same control as in the reference mode 2 is performed. It is configured. That is, the control means 60 is based on the determination of the other sleep state determination means 20 even if the sleep determination for at least one of the sleep state determination means 20 that has been canceled is not performed. It is comprised so that operation | movement of can be controlled.

したがって、この実施形態の睡眠検知による防犯装置によれば、帰宅しない居住者がある日は、その居住者に対応する睡眠状態判定手段２０を制御手段６０から切断しておくことにより、帰宅しない居住者がある日であっても、前記参考形態２と同様の住宅防犯機能を働かせることができる。 Therefore, according to the crime prevention apparatus based on sleep detection of this embodiment, on a day when there is a resident who does not go home, the sleep state determination means 20 corresponding to the resident is disconnected from the control means 60 so that the residence that does not go home. Even if a person is on a certain day, the same home crime prevention function as that of the reference mode 2 can be activated.

その他の構成及び作用効果は前記参考形態２と同様である。 Other configurations and operational effects are the same as the reference embodiment 2.
