Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic emergency alarm device and an automatic emergency alarm output method capable of saving power.

[0002]

2. Description of the Related Art Conventionally, there is an automatic emergency warning device as disclosed in, for example, Japanese Patent Application Laid-Open No. 5-52975. The technology disclosed in Japanese Patent Application Laid-Open No. 5-52975 will be briefly described. An output of a pulse sensor is repeatedly detected at predetermined time intervals, and when an emergency value exceeding a preset allowable range is continuously detected a plurality of times, an emergency alarm is issued. Is output. As a result, power saving can be achieved as compared with the case where the output of the pulse sensor is constantly detected, and an emergency alert is issued when an emergency value is continuously detected a plurality of times, resulting in sudden noise or the like. False alarms can be prevented. Further, it is conceivable to further reduce power consumption by intermittently performing the operation itself of the pulse sensor.

[0003]

However, in the above-described apparatus, the output of the pulse sensor is always intermittently detected irrespective of the state of the user, so that a predetermined amount of power is consumed for each detection. I was Therefore, even when the pulse rate does not interfere with normal life, predetermined power is consumed because the output of the pulse sensor is detected, and the power consumption increases. There is a problem that the battery life is shortened.

[0004] The above problems are not limited to the automatic emergency alarm device using a pulse sensor, but are based on the detection results of sensors that detect various abnormal states of a living body by consuming a predetermined amount of electric power. This is a common problem in automatic emergency alert systems that report emergency alerts.

Accordingly, an object of the present invention is to provide an automatic emergency alarm device and an automatic emergency alarm output method capable of saving power.

[0006]

According to the present invention, there is provided a first detecting section for intermittently detecting biological information, and detecting an abnormal state of the living body based on the biological information detected by the first detecting section. A control unit that outputs an emergency signal when the abnormal state of the living body is continuously detected, wherein the first detection unit has less power than the power required to detect the biological information. The apparatus further includes a second detection unit that detects biological information with electric power, and the control unit detects the biological information detected by the second detection unit at a desired interval, and controls the control unit by the second detection unit. Detecting the attention state of the living body based on the detected biological information,
The operation of the first detection unit is controlled according to the detection result of the caution state. Therefore, in accordance with the detection result of the caution state detected by the control unit based on the detection of the second detection unit that requires a small amount of power to detect the biological information, the power consumption required to detect the biological information is large, By controlling the operation of the first detection unit used for detection, power saving can be achieved as compared with the case where the first detection unit operates at constant time intervals.

The control section activates only the second detection section of the first and second detection sections when the attention state is not detected, and activates the first detection section when the attention state is detected.
When the configuration is such that only the second detection unit, which consumes a small amount of power for detecting biological information, normally performs detection (when the attention state is not detected), power consumption can be reduced. . Further, for example, when a living body such as a human needs attention, the first detection unit detects the biological information, so that it is possible to quickly determine whether the living body such as a human is in an abnormal state. That is, it is possible to reliably detect an abnormal state of a living body while saving power.

[0008] The first detecting section detects the biological information intermittently at intervals longer than the desired interval, and the control section detects the abnormal state when the abnormal state is detected. With a configuration in which the detection interval is shortened, the first detection unit that consumes a large amount of power for detecting biological information is detected at a long interval, so that power saving is achieved. Even if it is difficult to detect a caution state,
The abnormal state of the living body can be confirmed by the detecting unit, and the emergency state can be detected at an early stage, and the lifesaving rate is improved.

Preferably, the second detecting section is a body motion detecting section.

Preferably, the first detecting section is a pulse detecting section.

The above-described pulse detecting section is provided with a blue LED and a photosensor having a peak sensitivity at a blue wavelength, and further includes a mounting section that can be mounted on a user's wrist. Since a pulse can be detected from the wrist, and the detection unit can be mounted as if wearing a wristwatch, for example, an automatic emergency alarm device that is easy for the user to use can be provided.

With a configuration further including a notifying means for notifying the output of the emergency signal, it is possible to notify the surrounding people of the emergency condition of the user of the automatic emergency alarm device.

A first detecting step of intermittently detecting biological information; detecting an abnormal state of the living body based on the biological information detected by the first detecting step; A control step of outputting an emergency signal when detection is performed, wherein the first detection step detects biometric information with less power than the power required to detect the biometric information. In the control step, the biological information detected in the second detecting step is detected at a desired interval, and based on the biological information detected in the second detecting step. Detecting the attention state of the living body and controlling a detection interval in the first detection step according to a detection result of the attention state It was. For this reason, the power consumption required for the detection of the biological information is large in accordance with the detection result of the attention state detected in the control step based on the detection in the second detection step in which the power consumption required for the detection of the biological information is small, By controlling the detection interval in the first detection step used for detection, it is possible to save power compared to a method in which the first detection step is always executed at a constant time interval.

In the control step, when the caution state is not detected, only the second detection step of the first and second detection steps is executed, and when the caution state is detected, the first detection step is performed. If the detection step is performed, the power consumption is kept low because the detection is performed only in the second detection step in which the power consumption required for detecting the biological information is small in the normal state (when the attention state is not detected). Can be Further, for example, when a living body such as a human needs attention, the biological information is detected in the first detection step, so that it is possible to quickly determine whether the living body such as a human is in an abnormal state. That is, it is possible to reliably detect an abnormal state of a living body while saving power.

In the first detecting step, the biological information is intermittently detected at intervals longer than the desired interval, and in the control step, the first detection is performed when the abnormal state is detected. If the detection interval in the step is to be shortened, power is saved by performing detection at a long interval in the first detection step in which power consumption required for detecting biological information is large. However, even in the situation where it is difficult to detect the above-mentioned caution state, the abnormal state of the living body can be confirmed in the first detection step, and the emergency state can be detected at an early stage, and the survival rate can be improved.

It is preferable that the biological information detected in the second detection step is a body movement.

Preferably, the biological information detected in the first detecting step is a pulse.

If the information processing apparatus further includes a notification step of notifying the output of the emergency signal, it is possible to notify surrounding people of an emergency state of a living body such as a human.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be specifically described below based on an embodiment shown in the drawings.

FIG. 1 is a front view of the automatic emergency alarm device of the present embodiment. In FIG. 1, a pulse detecting unit 1 as a first detecting unit includes a blue LED 1a, which will be described later, and a photosensor 1b having a peak sensitivity to a blue wavelength, and is disposed inside a mounting unit 7. When the unit 7 is worn on the wrist w of the user, the unit 7 comes into close contact with the back of the wrist w of the user, and detects the pulse of the user intermittently. The light emitted from the blue LED 1a is applied to the back side of the user's wrist w, receives the reflected light whose light quantity changes with a change in the blood flow rate by the photo sensor 1b, and converts it into a pulse signal corresponding to the change in the received light quantity. That is, in the present example, a pulse is detected as biological information detected by the first detection unit, and a pulse signal corresponding to the detected pulse is output. The body movement detection unit 2 as the second detection unit is an acceleration sensor in which a magnet that vibrates according to the body movement is disposed in a coil, for example, and consumes little power by itself, and As a result, the magnet moves in the coil to generate an electromotive force, which is output as a body motion signal. That is, in the present example, a body motion is detected as biological information detected by the second detection unit, and a body motion signal corresponding to the body motion is output. Here, the relationship between the power consumption of the pulse detection unit 1 and the power consumption of the body motion detection unit 2 will be described. The pulse detection unit 1 consumes power for causing the LED to emit light, while the body motion detection unit 2 has a coil. The generated electromotive force is used. That is, the body motion detection unit 2 detects the body motion with less power than the pulse detection unit 1 needs to detect the pulse. The manual notification SW3 is operated by a user or the like to output an emergency signal described later. The setting and timing SW 4 can be operated by a user or the like to set an abnormal state or the like and to time the time display unit 6a. The backlight SW5 illuminates the display unit 6 when operated by a user or the like. Display 6
Includes a time display section 6a and an emergency alert display section 6b.
In this example, the mounting unit 7 has a wristwatch shape, and includes a pulse detection unit 1, a body movement detection unit 2, an analog circuit 8a described later,
8b, an automatic emergency alarm device including the control unit 9 and the like can be mounted on the wrist of the user.

FIG. 2 is a block diagram of this embodiment. In the figure, an analog circuit 8a performs noise removal and amplification of the pulse signal from the pulse detection unit 1. The analog circuit 8b
The noise removal and amplification of the body motion signal from the body motion detection unit 2 are performed. The control unit 9 includes a CPU 10 and a transmission circuit 11. The CPU 10 determines a caution state based on a body motion signal from the body motion detection unit 2, measures a pulse rate and determines an abnormality based on a pulse signal from the pulse detection unit 1, controls a pulse measurement interval, and performs an emergency signal. Outputs transmission signals and alarm signals. When a transmission signal from the CPU 10 is input, the transmission circuit 11 wirelessly issues an emergency alert. When an alarm signal from the CPU 10 is input, the alarm output unit 12 outputs an alarm sound. In FIG. 2, the same components as those in FIG. 1 are denoted by the same reference numerals.

FIG. 3 is a timing chart showing a series of operations from detection of body movement and measurement of the pulse rate to emergency notification according to the present embodiment. In the figure, (a) shows a conventional operation for measuring a pulse rate at a constant time interval, and (b) shows an operation of the present example. The pulse rate measurement time t is the time until the pulse detection section 1 operates to output a pulse signal, the CPU 10 measures the pulse rate and determines an abnormality, and determines the next pulse measurement interval by the pulse detection section 1. It's time. Also,
The body movement detection time t ′ is determined by whether the CPU 10 captures a body movement signal output by the body movement detection unit 2 to detect body movement, makes the CPU 10 determine a caution state, and determines whether to activate the pulse detection unit 1. It is time to do. In this example, t and t 'are both about 4 seconds.

Next, the operation will be described with reference to FIG.

The CPU 10 detects the body motion detector 2 at predetermined intervals.
Is detected (see FIG. 3 (b-1)).
The analog circuit 8b performs noise removal and amplification of the body motion signal from the body motion detection unit 2. The CPU 10 determines the attention state based on the detected body motion signal. In this example, the attention state is determined by determining the presence or absence of the user's body movement based on the detected body movement signal. When there is a body movement of the user, the CPU 10 determines that the user is in a non-attention state in which the user can move, and activates only the body movement detection unit 2 without operating the pulse detection unit 1. If there is no body movement of the user, the CPU 10 determines that the user is in a cautionary state where the user may fall into an abnormal state and may not be able to move, and continues to detect body movement and start detection of the pulse detection unit 1. . In this example, in order to reduce unnecessary operation of the pulse detection unit 1 based on a temporary malfunction of the body movement detection unit 2, the pulse detection unit 1 is operated when the body movement is not detected twice consecutively. .

The pulse detecting unit 1 mounted on the back side of the user's wrist w is controlled by the CPU 10 when the CPU 10 detects the alert state twice consecutively, detects a pulse at a predetermined interval, and outputs a pulse signal. Output. The analog circuit 8a performs noise removal and amplification of the pulse signal from the pulse detection unit 1. CP
U10 measures (calculates) the pulse rate based on the input pulse signal, and determines whether the measured (calculated) pulse rate is abnormal. In this example, the measured (calculated) pulse rate is a value (normal value) within a predetermined range (for example, 40 or more and less than 120) or an abnormal value (emergency value) that deviates from the predetermined range. An abnormality determination is made by determining whether or not there is. CPU1
If 0 determines that the pulse rate is a normal value, the operation of the pulse detection unit 1 is stopped, and if the CPU 10 determines that the pulse rate is an urgent value, the pulse detection unit 1 continues to detect the pulse. Also,
When the CPU 10 determines that the pulse value is an urgent value continuously plural times, it is determined that the user has fallen into an emergency state and the transmitting circuit 11
An emergency signal is output to When the transmission circuit 11 receives the emergency signal, it sends an emergency alert. The emergency alert transmitted from the transmission circuit 11 is received by, for example, an emergency center or the like,
Emergency services are dispatched.

For example, as shown in FIG. 3, the normal pulse measurement interval T and the body motion signal detection interval T'1 are 1 minute, and the pulse measurement interval T'2 when an attention state is detected is 10 seconds. The pulse is measured when the attention state is detected twice consecutively, and the emergency alert is notified when the emergency value is detected three times consecutively.
It is assumed that the user has fallen into an emergency state such as unconsciousness at time t1.

Conventionally, it takes (2 minutes + t) from the start of the detection of the emergency value at the time t2 to the notification of the emergency alert, and after the user falls into the emergency state, that is, (2) from the time t1. (Minute 15 seconds + t) (see FIG. 3A).

On the other hand, in the present embodiment, the attention state of the user who has become unconscious and unable to move is detected at time t2, and then the detection of the second attention state is started one minute later at time t3. The pulse measurement is started immediately after the detection of the attention state.
In other words, after the detection of the caution state is started at the time t2, the pulse measurement is started at (1 minute + t '), and the emergency alert is notified at (20 seconds + t) from the start of the pulse measurement. Therefore, after the user falls into the emergency state, that is, from the time t1, (1
An emergency call can be made in minutes 35 seconds + t + t ′) (see FIG. 3B).

As described above, in the normal state (when the attention state is not detected), only the body movement detection unit 2 that requires a small amount of power to detect the biological information performs the detection, so that the power consumption can be reduced. When the user falls into a state requiring attention, the pulse detection unit 1 measures the pulse and detects an abnormal state, so that it is possible to quickly determine whether the user is in an emergency state. In other words, since the abnormal state determination is performed using the pulse detection unit 1 having large power consumption only when necessary, it is possible to reliably detect the emergency state of the user while saving power.

Further, in this embodiment, in order to reduce unnecessary operation of the pulse detecting unit 1 due to a temporary malfunction of the body movement detecting unit 2, the pulse is measured when the attention state is detected twice consecutively. However, if the pulse is measured once the caution state is detected, unnecessary operation of the pulse detection unit 1 may increase, but after the user falls into an emergency state, that is, t1 An emergency call can be made in (35 seconds + t + t ') from the point in time, and the time required for notifying an emergency alert can be reduced as compared with the above example, and the survival rate of the user can be improved.

In the above, during normal times (when a caution state is not detected)
Has shown an example in which only a detection unit that consumes less power for detecting biological information performs detection, thereby saving power.
Next, at normal times, the detection unit that consumes a large amount of power required to detect biological information is operated intermittently at intervals longer than the detection interval of the detection unit that consumes a small amount of power, and the power consumption is large when an abnormal state is detected. FIG. 4 shows an example in which the detection interval of the detection unit is shortened to increase the frequency of detecting an emergency state. In the case of this example, the configuration is the same as that shown in FIG.

FIG. 4 is a timing chart showing a series of operations from detection of body movement and measurement of pulse rate to emergency notification according to the present embodiment. In the figure, (b) shows the above embodiment (FIG.
(B)) shows the operation, and (c) shows the operation of the present embodiment. The pulse rate measurement time t is the time until the pulse detection section 1 operates to output a pulse signal, the CPU 10 measures the pulse rate and determines an abnormality, and determines the next pulse measurement interval by the pulse detection section 1. It's time. Also, the body motion detection time t
′ Is the time from when the CPU 10 captures a body movement signal output by the body movement detection unit 2 to detect body movement, the CPU 10 determines a caution state, and determines whether to activate the pulse detection unit 1 or not. is there. In this example, t and t 'are both about 4 seconds.

Next, the operation will be described with reference to FIG.

The CPU 10 detects a body movement signal from the body movement detection unit 2 at predetermined intervals, and determines the attention state based on the detected body movement signal as described above. If the CPU 10 cannot detect the user's body motion twice in succession, it determines that the user is in a cautionary state in which the user may fall into an abnormal state and cannot move. 1 is started to be detected.

The pulse detector 1 mounted on the back side of the wrist w of the user normally detects a pulse at an interval longer than the detection interval of the body motion signal and outputs a pulse signal. In addition, the CPU 10
When detecting the attention state, the pulse is detected at an interval shorter than the detection interval of the body motion signal, and the pulse signal is output. CPU
Reference numeral 10 measures (calculates) the pulse rate based on the pulse signal input via the analog circuit 8a, and performs the abnormality determination of the measured (calculated) pulse rate as described above. If the CPU 10 determines that the pulse rate is a normal value, the operation of the pulse detection unit 1 is returned to the normal operation (when the attention state is not detected). Causes the pulse to be detected at intervals shorter than normal times (when no attention is detected).
When the CPU 10 determines that the pulse value is an urgent value continuously multiple times, the CPU 10 determines that the user has entered an emergency state and outputs an emergency signal to the transmission circuit 11. When receiving the emergency signal, the transmission circuit 11 issues an emergency alert. The emergency alert transmitted from the transmission circuit 11 is received by, for example, an emergency center or the like, and an emergency service or the like is dispatched.

For example, as shown in FIG. 4, the detection intervals T'1 and T'3 of the body movement are 1 minute, which is normal (when no attention state is detected).
The pulse measurement interval T'4 is 5 minutes, the pulse measurement interval T'5 when an abnormal condition is detected is 10 seconds, and when an emergency value is detected three times in succession, an emergency alert is issued and the user is notified. It is assumed that the body is constantly moving unconsciously (for example, a state where the user is riding a vehicle), and it is assumed that the user has fallen into an emergency state such as unconsciousness at time t4.

In this case, in the above embodiment (FIG. 4B), even if the user's body movement is intermittently detected, the caution state can be detected because the user's body is constantly moving. Not
As a result, the pulse is not measured (see FIG. 4B-2). Therefore, even if the user falls into an emergency state at t4,
The emergency state cannot be detected (see FIG. 4B).

On the other hand, in this example (FIG. 4C), the body movement and the pulse are detected from the normal state (when the attention state is not detected), so that even if the attention state cannot be detected, the abnormality is detected by the pulse detection. The state can be detected. Specifically, after the detection of the emergency value is started at t5, an emergency call can be made in (20 seconds + t). That is, an emergency call can be made at (1 minute 35 seconds + t) after the user falls into an emergency state, that is, from time t4 (FIG. 4).
See (c-2). ). Therefore, power saving can be achieved by operating the pulse detection unit 1 that consumes a large amount of power for detecting the biological information at long intervals. Further, even in a situation where the control unit 9 cannot easily detect the caution state, for example, when the user is riding on a vehicle such as a car and the body of the user is constantly moving, the pulse detection unit 1 intermittently monitors the pulse. , The abnormal state of the user can be confirmed, and the life saving rate is improved.

In each of the above examples, the CPU 1
0 outputs an alarm signal to the alarm output unit 12 when outputting an emergency signal to the transmission circuit 11, and the alarm output unit 12 sounds an alarm when the alarm signal is input. Therefore, when the user falls into an emergency state, surrounding people can quickly notice the emergency state of the user, and can promptly make an emergency call and rescue the user.

In each of the above examples, the manual notification SW3 outputs a manual notification signal to the CPU 10,
0 outputs a transmission signal of an emergency alert and an alarm signal when a manual notification signal is input. Therefore, by pressing the manual notification switch SW3 when the user feels danger, the user can be notified of an emergency warning before the emergency state is entered, and the survival rate of the user is further improved.

In each of the above examples, the pulse rate and the body movement of a human are used as the biological information. However, the biological information is not limited thereto, and can be changed as appropriate. For example, the pulse rate of another animal or blood pressure may be used.

In each of the above examples, the first and second
Although the pulse detector and the body motion detector are used as the detectors for detecting different states (pulse and body motion), the detector is not limited to this and can be changed as appropriate. For example, the first detection unit is a pulse detection unit having a large power consumption including an LED and a photo sensor, and the second detection unit is a consumption unit including a piezoelectric element that detects vibration accompanying a pulse and outputs a piezoelectric signal corresponding to the pulse. A pulse detector having small power may be used, and two detectors having different power consumptions may detect the same state (pulse).

In each of the above examples, an acceleration sensor having a magnet disposed in a coil is used as a body movement detecting unit. However, the body movement detecting unit is not limited to this and can be appropriately changed.
It is sufficient that the pulse detector detects the body movement of the living body with less power than the power required for detecting the pulse of the living body, and an acceleration sensor using a piezoelectric element, a semiconductor acceleration sensor, or the like can be used. Here, generally, the current consumption when detecting a pulse using an LED and a photo sensor is about 10
In contrast, the current consumption when detecting a body motion using an acceleration sensor using a piezoelectric element or a semiconductor acceleration sensor is about 1 mA or less, which is smaller than the above.

In each of the above examples, the pulse rate and the body movement detection interval, the pulse measurement time and the body movement detection time are 4
Seconds, 10 seconds, 1 minute, and 5 minutes were used, but the detection interval is not limited to this and can be changed as appropriate.

In each of the above examples, a range of 40 or more and less than 120 is used as a reference range for determining a pulse rate abnormality, but the reference range is not limited to this and can be changed as appropriate.

In the above example, an alarm output unit that outputs an alarm sound is used. However, the alarm output unit is not limited to this, and can be appropriately changed. For example, L
An alarm may be performed by lighting an ED or the like.

[0047]

According to the automatic emergency alert device and the automatic emergency alert output method of the present invention, the control unit or the control unit based on the detection in the second detection unit or the second detection step which consumes a small amount of power for detecting the biological information is performed. According to the detection result of the cautionary state detected in the control step, the power consumption required for detecting the biological information is large, and the operation in the first detection unit or the first detection step used for detecting the abnormal state is controlled. Power saving can be achieved as compared with the case where biological information for detecting an abnormal state is always detected at a constant time interval.

When the attention state is not detected, only the second detection unit of the first and second detection units or the first and second detection steps is operated, or only the second detection step is executed. If the first detection unit is operated or the first detection step is executed when the attention state is detected, the power consumption required for detecting the biological information in the normal state (when the attention state is not detected) Since the detection is performed only in the second detection unit or the second detection step where the power consumption is small, power consumption can be suppressed low. Further, for example, when a living body such as a human needs attention, the biological information is detected in the first detection unit or the first detection step, so that it is possible to quickly determine whether the living body such as a human is in an abnormal state. Can be determined. That is, it is possible to reliably detect an abnormal state of a living body while saving power.

In the first detecting section or the first detecting step, the biological information is intermittently detected at an interval longer than a desired interval. If the detection interval in the detection unit or the first detection step is set to be short, the detection is performed at a long interval in the first detection unit or the first detection step in which the power consumption required for detecting the biological information is large. Even in a situation in which the power consumption is achieved and the control unit is difficult to detect the caution state due to some factor, the abnormal state of the living body can be confirmed in the first detection unit or the first detection step,
Early detection of an emergency condition becomes possible, and, as a result, the survival rate is improved.

The pulse detecting unit as a detecting unit is a blue LED
And a photosensor having a peak sensitivity at the blue wavelength, and a configuration further including a mounting portion that can be mounted on the user's wrist, in addition to the above effects, it is possible to detect a pulse from the wrist, for example, a wristwatch Since the detection unit can be mounted as if wearing the device, it is possible to provide a user-friendly automatic emergency alarm device.

Since the notification for notifying the output of the emergency signal is performed, it is possible to notify the surrounding people of the emergency condition of the user of the automatic emergency alarm device.
