Description

The present invention relates to a mobile monitoring terminal that is attached to a user and monitors the state of the user, and a program used for the mobile monitoring terminal.

Conventionally, there has been a monitoring system that automatically detects an event such as a health abnormality in a user's daily life by a monitoring terminal attached to a user such as an elderly person and notifies the monitoring center. For example, Patent Document 1 below describes that only when a terminal is attached to a user, safety confirmation information is generated depending on the presence or absence of the user's body movement and transmitted to the center (life monitoring process). ..

Japanese Unexamined Patent Publication No. 2006-141902

However, when the life monitoring process is executed only when the user is wearing the monitoring terminal as in the technique described in Patent Document 1, the user is loosely attached to the monitoring terminal when the user is sleeping. If it is recognized that the monitoring terminal is not attached even though the monitoring terminal is not intentionally removed, the user's life abnormality cannot be detected. On the other hand, it is necessary to avoid a situation in which the sleep of a user who does not have an abnormal life is disturbed.

In view of the above circumstances, an object of the present invention is to provide a mobile monitoring terminal and a program capable of determining the possibility of unintended removal of the monitoring terminal by the user and continuing life monitoring as needed. There is.

In order to achieve the above object, the mobile monitoring terminal according to one embodiment of the present invention is a mobile monitoring terminal that monitors the occurrence of a user's life abnormality, and includes a wearing detection means, a motion sensor, a body motion detection means, and the like. It has an abnormality determination means. The wearing detection means detects the wearing state of the mobile monitoring terminal to the user. The motion sensor detects the motion of the mobile monitoring terminal and outputs motion data. The body motion detecting means detects the body motion of the user based on the motion data. The abnormality determining means determines that a life abnormality has occurred in the user when the state in which the body movement is not detected continues for a predetermined monitoring time. Further, when the abnormality determining means detects the removal of the mobile monitoring terminal, it determines whether or not it is necessary to continue monitoring the living abnormality based on the detection status of the body movement.

As a result, the mobile monitoring terminal determines whether or not it is necessary to continue the life monitoring based on the detection status of the user's body movement when the mobile monitoring terminal is removed, so that the mobile monitoring terminal is an unintended monitoring terminal in an inactive state such as sleeping. The possibility of removal can be determined, and life monitoring can be continued if necessary.

The abnormality determining means may determine whether or not to continue monitoring the living abnormality based on the detection status of the body movement at least before or after the removal detection.

As a result, the mobile monitoring terminal can determine with high accuracy whether or not it is necessary to continue the life monitoring by checking the body movement detection status at least before or after the removal detection.

The abnormality determining means continues to monitor the living abnormality when the body movement is not detected continuously for the predetermined period, and when the body movement is detected within the predetermined period, the living abnormality is detected. Monitoring may be terminated. In particular, the necessity of continuing the monitoring of the living abnormality may be determined according to the detection status of the body movement immediately before the removal detection, with the fixed time before the removal detection as the predetermined period.

As a result, the mobile monitoring terminal detects an unintended removal that occurred while the user was sleeping when no body movement was detected in the predetermined period before, the predetermined period after, or the predetermined period before and after the removal detection. If body movement is detected in any of the predetermined periods before and after, it is considered that the removal is intended by the user, and the life monitoring can be terminated.

The abnormality determining means determines the living abnormality based on the first criterion in the monitoring of the living abnormality while wearing the mobile monitoring terminal, and in the monitoring of the living abnormality that continues after the removal detection, the first one. The above-mentioned living abnormality may be judged based on a second standard that is stricter than the standard.

As a result, the mobile monitoring terminal can reliably detect the user's body movement even in the removed state by making the standard of abnormality judgment stricter in the life monitoring after the removal detection than the life monitoring while wearing it. It is possible to prevent erroneous judgment of life abnormalities. Here, the first criterion and the second criterion may be the above-mentioned monitoring time (the second criterion has a longer monitoring time), or the threshold value of the movement data for the above-mentioned body movement detection (second reference). The threshold value is lower than the standard of).

When the removal of the mobile monitoring terminal is detected, the step of determining the necessity of continuing the monitoring of the living abnormality based on the detection status of the body movement is executed.

As described above, according to the present invention, it is possible to determine the possibility of unintentional removal of the monitoring terminal by the user and continue life monitoring as needed. However, this effect does not limit the present invention.

It is a figure which shows the structure of the mobile monitoring terminal which concerns on one Embodiment of this invention. It is a flowchart which showed the flow of the life monitoring process by the said mobile monitoring terminal.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[Configuration of mobile monitoring terminal]
FIG. 1 is a diagram showing a configuration of a mobile monitoring terminal according to an embodiment of the present invention.

The mobile monitoring terminal 100 according to the present embodiment is, for example, a wristband type (wristwatch type) wearable terminal, and is worn on the wrist or arm of a user such as an elderly person. In addition to the wristband type, for example, a pendant type that can be hung from the neck, a head mount type that can be attached to the head such as an ear, and a waist-mounted type such as a belt shape or a belt loop hanging shape can be taken.

As shown in the figure, the mobile monitoring terminal 100 includes an acceleration sensor 11, a mounting sensor 12, a battery 13, a wireless communication unit 14, a notification unit 15, an operation display unit 16, an emergency button 17, and a control unit 18.

The acceleration sensor 11 is composed of, for example, a three-axis sensor, and detects the movement of the mobile monitoring terminal 100 (the movement of the user wearing the mobile monitoring terminal 100). The acceleration sensor 11 outputs acceleration data detected in a predetermined sampling cycle. Instead of the acceleration sensor 11, another motion sensor such as an angular velocity sensor may be used.

The wearing sensor 12 is provided, for example, on the wristband portion of the mobile monitoring terminal 100, and detects the wearing state of the mobile monitoring terminal 100 on the human body (arm) of the user. As the detection method of the mounting sensor 12, for example, a capacitance type is adopted, but other types of sensors such as an inductive type, an ultrasonic type, a photoelectric type, and a magnetic type may be used. When the mobile monitoring terminal 100 has a band shape and has a structure in which both ends thereof are connected and worn on the user's wrist, the connection between the ends is detected by a contact switch or an energized state, thereby wearing / not wearing. It can also detect wearing.

The battery 13 supplies electric power to each part of the mobile monitoring terminal 100. As the battery 13, for example, a rechargeable battery such as a lithium polymer battery, a lithium ion battery, or a nickel hydrogen battery is used.

The wireless communication unit 14 wirelessly communicates with the remote monitoring center C via a mobile communication network such as 3G or LTE (Long Term Evolution), and the user abnormality detected by the mobile monitoring terminal 100 (control unit 18). To the monitoring center C. Further, the wireless communication unit 14 can also wirelessly communicate with a security terminal in the house connected to the monitoring center C by, for example, BLE (Bluetooth (registered trademark) Low Energy) or a specific low power radio.

A controller is stationed at the monitoring center C, and when an abnormality report is received from the mobile monitoring terminal 100 (or via a security terminal in the house), necessary measures such as dispatching emergency personnel to the user's site are taken. Taken.

The notification unit 15 is configured as, for example, a vibration device, and notifies the user of an abnormality or an operation reception by a stimulus caused by vibration. In addition to vibration, notification may be made by voice.

The operation display unit 16 is configured as, for example, a touch panel display, and executes various display processes such as an abnormality notification together with or in place of the notification by the notification unit 15. Further, the operation display unit 16 may function as an input means for the user's cancel operation for abnormality detection (report). A separate dedicated cancel button may be provided as an input means for the cancel operation.

The emergency button 17 is an emergency operation unit for the user to make an emergency call to the monitoring center C in an emergency. For example, two emergency buttons 17 are provided, and an emergency report is input when, for example, two emergency buttons 17 are pressed at the same time.

The control unit 18 comprehensively controls each unit of the mobile monitoring terminal 100, and executes various calculations in response to inputs from the above sensors and operation units. The control unit 18 monitors whether or not a fall abnormal state, an emergency abnormal state, or a life abnormal state has occurred in the user by each monitoring processing unit of the life monitoring unit 181, the emergency monitoring unit 182, and the fall monitoring unit 183. To execute.

The life monitoring unit 181, the emergency monitoring unit 182, and the fall monitoring unit 183 may be configured as dedicated hardware circuits or software (programs), respectively. When the life monitoring unit 181 and the emergency monitoring unit 182 and the fall monitoring unit 183 are configured as software, they are stored in a storage device such as a RAM (Random Access Memory) or a flash memory (not shown) of the mobile monitoring terminal 100. Hereinafter, these three types of monitoring processes will be described.

(Life monitoring)
The life monitoring means that the life monitoring unit 181 of the control unit 18 monitors whether the user (the wearer of the mobile monitoring terminal 100) is moving to the extent that it occurs in daily life based on the output of the acceleration sensor 11, and the user. This is a function to notify when it is detected that the person is unable to move due to a sudden illness or the like.

Specifically, the life monitoring unit 181 detects movement (body movement) from the output of the acceleration sensor 11 in a state where the user is wearing the mobile monitoring terminal 100 (detected by the wearing sensor 12), and performs daily life. When the level of body movement does not occur continuously for a certain period of time (for example, 1 hour), it is determined that the user has a living abnormality.

The presence or absence of body movement is determined by observing the peak or the amount of change in the acceleration data acquired from the acceleration sensor 11. For example, 1) when an acceleration peak value of a certain value or more (for example, 12 m / s ² ) is detected, or 2) when the amount of acceleration change per unit time (for example, 1 minute) exceeds a certain value, life monitoring Unit 181 determines that the user has body movements.

Regarding 2) above, specifically, since the acceleration data when the user moves causes a large change in the value in a short cycle, the life monitoring unit 181 sets the difference from the value of the immediately preceding acceleration data. The amount of change in acceleration for each unit time is defined as the amount obtained and the absolute value of this difference integrated over the above unit time.

Then, the life monitoring unit 181 notifies the user that the life abnormality has been determined by the vibration or sound of the notification unit 15 or the screen of the operation display unit 16, and after the notification, during a predetermined cancellation time (for example, 10 seconds). When body movement is detected in, or when a predetermined cancel operation is input from the user, the life abnormality is canceled (the abnormality is not reported to the monitoring center C).

Although the details will be described later, in the present embodiment, when the life monitoring unit 181 detects the removal of the mobile monitoring terminal 100 from the user, the life monitoring unit needs to continue the life monitoring according to the body movement detection status of the user at that time. judge. That is, when the connection portion of the band of the mobile monitoring terminal 100 is disconnected while the user is not active, such as while sleeping, or the mobile monitoring terminal 100 is displaced, the user is separated from the human body and comes into contact with the human body. Determine the situation in which the life monitoring process needs to be performed, such as when the sensor is not detected, and continue the life monitoring process. Specifically, the life monitoring unit 181 continues the life monitoring by regarding the user as sleeping if the user does not move at the time of removal, and ends the life monitoring if the user has body movement at the time of removal.

Further, although not shown, the control unit 8 continuously records the detection result of the user's body movement (acceleration data output from the acceleration sensor 11) in a storage device such as a RAM or a flash memory. The life monitoring unit 181 determines whether or not the above life monitoring needs to be continued with reference to the recorded body movement detection result.

(Emergency monitoring)
The emergency monitoring is a function in which the emergency monitoring unit 182 of the control unit 18 notifies the monitoring center C when the user presses the emergency button 17 in search of an emergency response by the monitoring center C.

Specifically, when the user presses and holds the emergency button 17 (for example, presses it for 2 seconds), the emergency monitoring unit 182 determines that the user has an emergency abnormality. Then, the emergency monitoring unit 182 notifies the monitoring center C of the emergency abnormality of the user, and notifies the user that the abnormality has been confirmed via the notification unit 15 or the operation display unit 16.

Even while the user is experiencing a life abnormality or a fall abnormality, if the emergency abnormality occurs, the emergency abnormality is prioritized.

(Fall monitoring)
The fall monitoring is a function in which the fall monitoring unit 183 of the control unit 18 automatically detects a fall of a user (the wearer of the mobile monitoring terminal 100) based on the output of the acceleration sensor 11 and reports the occurrence of a fall accident. be.

Specifically, the fall monitoring unit 183 detects a fall event having a characteristic of falling from the output of the acceleration sensor 11 while the user is wearing the mobile monitoring terminal 100, and evaluates the detection result. Detects a fall.

If a user stands up and walks within a predetermined time (for example, 15 seconds) after detecting a fall, the fall monitoring unit 183 does not confirm the fall abnormality and automatically cancels the detection of the fall event. ..

Further, when the fall monitoring unit 183 determines that the fall is abnormal, the user is notified by the vibration or sound of the notification unit 15 or the screen of the operation display unit 16, and after the notification, during a predetermined cancellation time (for example, 20 seconds). When a predetermined cancel operation is input from the user, the fall abnormality is canceled (the abnormality is not reported to the monitoring center C). The method of detecting the body movement of the user may be the same as the detection method in the life monitoring.

[Operation of mobile monitoring terminal]
Next, the monitoring operation of the mobile monitoring terminal 100 configured as described above will be described focusing on the life monitoring process. In the following description, the control unit 18 of the mobile monitoring terminal 100 or each monitoring unit will be described as the main operating body, but this operation is also performed in cooperation with the program executed under the control of the control unit 18. ..

The life monitoring process is started when the attachment of the mobile monitoring terminal 100 to the user is detected. When the user is conscious, the user's arm is moved with a certain frequency, and when the state of almost no movement continues, it is considered that the user is sleeping.

Therefore, in the life monitoring process, when the life monitoring unit 181 detects the removal of the mobile monitoring terminal 100 from the user, the detection result of the recorded body movement in 20 minutes before the detection (hereinafter, body movement record). If the user has significant body movements, it is determined that the user is in an active state, and the above removal is regarded as the removal intended by the user, and the life monitoring is terminated.

On the other hand, if the user does not have significant body movement in the 20 minutes before the detection, the life monitoring unit 181 determines that the user is in an inactive state (sleeping), and the removal is an unintended removal by the user. Consider it as a continuation of life monitoring.

Here, the reference time of the body movement detection result before the removal detection is set to 20 minutes. Generally, the duration of REM sleep in which a human is in a light sleep state is about 20 minutes on average. Therefore, if no significant body movement is detected in 20 minutes before the removal detection, it can be estimated that the user is at least in the REM sleep state.

Specifically, in the determination of the body movement, 1) when the integrated value of the acceleration change amount per unit time (for example, 1 minute) continues for 20 minutes or less, or 2) a certain value or more (for example, 1 minute). Criteria such as when the acceleration peak value of 12 m / s ² ) is not detected for 20 minutes are used.

However, since the sleeping user is in a state close to rest, the reference value of the body movement determination in the determination of the activity state is set to a lower reference value than the reference value in the life monitoring process at the time of wearing, and is regarded as a significant body movement. It may be easy to detect. The low reference value is, for example, the acceleration peak value is ^{less than 10 m / s 2,} but the lower reference value is for an index other than the acceleration peak value (for example, the integrated value of the acceleration change amount per unit time). It may be used.

FIG. 2 is a flowchart showing the flow of the life monitoring process by the life monitoring unit 181.

As shown in the figure, the life monitoring unit 181 determines whether or not the removal of the mobile monitoring terminal 100 from the user is detected by the mounting sensor 12 (step 21).

When it is determined that the removal is detected (Yes in step 21), the life monitoring unit 181 refers to the body movement record for 20 minutes before the removal detection (step 22).

As a result of referring to the body movement record, when it is determined that the user has significant body movement in 20 minutes before the removal detection (Yes in step 23), the life monitoring unit 181 further acquired from the acceleration sensor 11. Regarding the acceleration data, based on the integrated value of the acceleration change amount per unit time and the acceleration peak value described above, the user's body movement for 1 minute after the removal detection was monitored, and whether the user had significant body movement. It is determined whether or not (step 24).

If it is determined that the user has significant body movement even within 1 minute after the removal is detected (Yes in step 24), the life monitoring unit 181 indicates that the user is active and the removal is intentional by the user. The life monitoring process is terminated (step 25).

On the other hand, when it is determined that the user does not have significant body movement in either step 23 (20 minutes before the removal detection) or step 24 (1 minute after the removal detection) (No in step 23 or step 24), life The monitoring unit 181 considers that the user is inactive (sleeping) and the removal is not intended by the user, and continues the life monitoring process (step 26).

Further, when it is determined in step 21 that the removal of the mobile monitoring terminal 100 is not detected (No in step 21), the life monitoring unit 181 executes normal life processing, and the acceleration data acquired from the acceleration sensor 11 is described above. Based on the integrated value of the amount of change in acceleration per unit time and the peak value of acceleration, it is determined whether or not the user has significant body movement (step 27).

When it is determined that the user does not have significant body movement (No in step 27), the life monitoring unit 181 determines whether or not the state without significant body movement has continued for 60 minutes (step 28).

When it is determined that the state without significant body movement has continued for 60 minutes (Yes in step 28), the life monitoring unit 181 determines that a life abnormality has occurred (step 29). After that, the life monitoring unit 181 notifies the user that the life abnormality has been determined by the vibration or sound of the notification unit 15 or the screen of the operation display unit 16, and after the notification, a predetermined cancellation time (for example, 10 seconds) If body movement is detected in the meantime, or if a predetermined cancel operation is input from the user, the life abnormality is canceled (the abnormality is not reported to the monitoring center C).

The life monitoring unit 181 executes the above processing every time the wearing of the mobile monitoring terminal 100 is detected.

Here, when the removal of the mobile monitoring terminal 100 is detected, it is considered that the mobile monitoring terminal 100 is touching the user's wrist, but it is more difficult to detect the body movement than while wearing the mobile monitoring terminal 100. In the life monitoring process in the continuous monitoring in the above step 26, the life monitoring unit 181 lowers the sensitivity of the abnormality determination as compared with the normal life monitoring process executed during wearing, that is, the determination standard of the life abnormality is a stricter standard. It may be set to to make it difficult to be judged as an abnormal life.

For example, when the life monitoring unit 181 decides to continue the life monitoring, the monitoring time is extended by 20 minutes, the remaining monitoring time is extended by 1.5 times, the counting speed of the remaining monitoring time is slowed down, and the like. , The monitoring time for judging that the life is abnormal is longer than that during wearing. In addition to the monitoring time, the life monitoring unit 181 may use a reference value lower than that during wearing for different criteria such as lowering a reference value (acceleration threshold value, etc.) to determine that there is body movement. good. As a result, even if the movement of the mobile monitoring terminal 100 is small, it is easy to determine that there is body movement, so that false alarms of life abnormalities are less likely to occur.

[summary]
As described above, according to the present embodiment, when the mobile monitoring terminal 100 is removed from the user, the mobile monitoring terminal 100 determines the detection status of the user's body movement in a predetermined period before and after the removal. If the user does not have significant physical activity during the predetermined period, the user is sleeping, and the above removal can be regarded as an unintended removal by the user, and the monitoring of life abnormalities can be continued.

[Modification example]
The present technology is not limited to the above-described embodiment, and can be variously modified without departing from the gist of the present technology.

In the above-described embodiment, the life monitoring process is terminated when significant body movement is detected in the user in any of the predetermined periods (20 minutes before detection and 1 minute after detection) before and after the detection of removal. However, the life monitoring unit 181 omits one of the body movement detection processes (one of the processes of steps 22 and 23 in FIG. 2 and one of the processes of step 24) in the predetermined period before and after the removal detection. You may.

In addition, the life monitoring unit 181 ends the life monitoring when the body movement is detected in any one of the predetermined periods before and after the removal detection, and the life monitoring when the body movement is not detected in any of the predetermined periods before and after the removal. May continue. That is, when the determination result of step 23 in FIG. 2 is No, the determination in step 24 in FIG. 2 is further executed, and if body movement is detected in 1 minute after the detection in step 24, the life monitoring process is terminated. May be good.

In the above-described embodiment, an example is shown in which the body movement record of the user referred to when the removal of the mobile monitoring terminal 100 is detected in the life monitoring process is recorded in the storage device (flash memory) of the mobile monitoring terminal 100. rice field. However, the body movement record may be transmitted to another device via the wireless communication unit 14 and constantly recorded each time the acceleration data is output from the acceleration sensor 11. Here, the other device may be the monitoring center C or other external server, or may be a home server installed at the home of the user who wears the mobile monitoring terminal 100. In this case, the life monitoring unit 181 determines whether or not the life monitoring needs to be continued by receiving and referring to the body movement record from the other device via the wireless communication unit 14 at the time of the removal detection. Alternatively, instead of recording the presence or absence of body movement determined based on the acceleration data as a body movement record, the acceleration data for a predetermined period used for the determination is recorded as it is in the mobile monitoring terminal 100, and the removal is detected at the time of detection. The configuration may be such that the presence or absence of body movement is determined based on the acceleration data to determine the necessity of continuing life monitoring.

In the above-described embodiment, the life monitoring unit 181 determines the sleeping state (inactive state) of the user based on the duration of the state in which no significant body movement (predetermined acceleration) of the user is detected. However, the life monitoring unit 181 determines the sleep state based on the detection frequency (for example, several times an hour) of acceleration equal to or higher than a predetermined value (for example, acceleration to the extent that the user is considered to have turned over). May be good.

In the above embodiment, an example is shown in which the mobile monitoring terminal 100 is a wristband type terminal that can be worn on the user's arm, but the mobile monitoring terminal 100 is, for example, a belt type that can be worn on the user's waist or abdomen. Etc., it may be attached to various other parts of the user's body.

In the above-described embodiment, the description has been made on the premise that the mobile monitoring terminal 100 has an emergency monitoring function by the emergency monitoring unit 182 and a fall monitoring function by the fall monitoring unit 183, but the mobile monitoring terminal 100 has an emergency monitoring function and a fall. It does not have to have a monitoring function.

In the above-described embodiment, the mobile monitoring terminal 100 is configured to include various sensors, a notification unit, an operation display unit, a wireless communication unit, and the like as wearable terminals, but at least a part of each of these parts of the mobile monitoring terminal 100. Is provided in another device (for example, a mobile terminal such as a smartphone carried by a user), and the same processing as in the above embodiment may be executed by the cooperation processing with the other device.
