Description

The present invention relates to a life monitoring system that determines whether a monitoring target person has returned home when a monitoring target person such as an elderly person living alone has gone out.

Along with the increase in the number of people being watched over, such as the elderly living alone, the information on the life behavior of the people watched over is collected to watch over the life of the people watched over. There is a need for a system that supports the care of the elderly.

Conventionally, a human sensor is installed in the home of the person being watched over, and based on the result of the human sensor, that is, which human sensor installed in the house senses and reacts to the movement of the person. There is a life watching system that watches the life of the person being watched over (for example, see Patent Document 1). In this life monitoring system, after any human sensor provided in the house, for example, a human sensor installed in the living room reacts, it is installed in another place even after a predetermined time has passed. When the presence sensor does not react, it is determined that the person being watched has moved from any location in the house to the living room. And, for example, when the person being watched over stays in any place in the house for a long time exceeding a predetermined time set in advance, it is determined that an abnormality has occurred in the person being watched over in advance. A notification is sent to the notification destination that has been set.

JP 2003-132462 A

By the way, in the above-mentioned life monitoring system, if any person sensor provided in the house reacts even once after the person to be watched goes out, the person to watch over returns and the person sensor reacts. It is determined that there is a person to watch over at the place. Here, the human sensor may malfunction due to the influence of a small animal such as a mouse, the shaking of the curtain, or the wind. In addition, even if there is no malfunction of the human sensor, the data error due to the noise in the communication channel when collecting the data indicating the human sensor's sensitivity result or the malfunction of the device collecting the data indicating the human sensor result An incorrect sensitivity result may be acquired due to recognition or the like. When such human sensor malfunctions occur, it is determined in the conventional life monitoring system that the person being watched has come home even if the person being watched is not actually going home There is. Therefore, for example, when the human sensor installed at the entrance malfunctions, it is determined that the person being watched over stays at the door for a long time exceeding a predetermined time, and the person being watched over changes. There was a problem that an erroneous notification that the error occurred occurred.

An object of the present invention is to provide a life watching system that can reliably determine that a person to be watched has gone home by eliminating erroneous homecoming judgment due to a malfunction or the like of a human sensor.

The life monitoring system according to claim 1 is a human sensor that detects movements of people installed in a plurality of places in a living area where a person to be watched lives, and reaction times and reaction times of the human sensors. Sensitive result storage means for storing a sensitive result including: and whether or not a first predetermined time has elapsed since any one of the human sensors has reacted after it has been determined that the person to be watched has gone out Sensitivity results stored in the sensitivity result storage means when it is determined that the first predetermined time elapse judgment means and the first predetermined time elapse judgment means determine that the first predetermined time has elapsed. And a return determination means for determining that the person to be watched has returned when the number of reactions of the human sensor within the first predetermined time is equal to or greater than the first predetermined number of times. With features That.

According to the life monitoring system according to claim 1, after it is determined that the person to be watched has gone out, the first predetermined time after any human sensor installed in the living area reacts If the human sensor reacts for the first predetermined number of times or more, it is determined that the person being watched over has returned home. Therefore, it is possible to prevent the monitoring target person from being erroneously determined to have returned home due to a reaction due to the invasion of a small animal, a malfunction of the human sensor, or the like, and to determine whether the monitoring target person has returned home with high accuracy.

Further, in the life watching system according to claim 2, after the return home determination means determines that the person to be watched has gone out by the human sensor installed in a place other than the entrance in the living area, It reacts first, and when the number of reactions of the human sensor within the first predetermined time is equal to or greater than the first predetermined number of times, after the first predetermined time has elapsed, When the number of reactions of the human sensor in time is equal to or more than a second predetermined number, it is determined that the person to be watched has come home.

According to the life monitoring system according to claim 2, when it is determined that the person to be watched is going home because the human sensor other than the human sensor installed at the entrance reacts, the first predetermined Based on whether or not the human sensor has reacted more than the second predetermined number of times within the second predetermined time after the passage of time, it is determined based on the result of the human sensor installed at a place other than the entrance. It is possible to determine whether or not the person being watched over is home and to accurately determine whether or not the person being watched home is home. Therefore, it is possible to reliably determine whether or not the person being watched over has returned home with even higher accuracy.

Further, in the life watching system according to claim 3, after the return determination means determines that the person to be watched has gone out by the human sensor installed in a place other than the entrance in the living area, It reacts first, and when the number of reactions of the human sensor within the first predetermined time is equal to or greater than the first predetermined number of times, after the first predetermined time has elapsed, When the number of reactions of the human sensor in time is less than the second predetermined number of times,
It is determined that the location of the person being watched over is unknown.

According to the life watching system according to the third aspect, when it is impossible to accurately determine that the person to be watched has come home, it is determined that the whereabouts of the person to be watched is unknown. In other words, if it is not possible to accurately determine the status of the person being watched over, the location of the person being watched for is unknown, and an abnormality occurs in the person being watched even though the person being watched is not home It is possible to prevent an erroneous determination such as determining that it has been performed.

According to the present invention, after the person to be watched goes out, the first time after the human sensor reacts first.
Until the predetermined time elapses, it is determined that the person to be watched has come home when the human sensor has reacted more than the first predetermined number of times. Therefore, due to the invasion of small animals, malfunction of human sensor, etc.
Even if the watching target person has not returned home, it can be reliably prevented that the monitoring target person has returned home, and it can be accurately determined whether or not the watching target person has returned home.

Further, according to the present invention, when the human sensor installed in a place other than the entrance reacts first and there is a reaction more than the first predetermined number of times within the first predetermined time, the second sensor It is determined whether or not the person to be watched has come home based on whether or not the human sensor has reacted more than the second predetermined number of times within the predetermined time. Therefore, it is possible to reliably prevent an erroneous determination based on a malfunction or the like and to accurately determine whether or not the person to be watched has come home with higher accuracy.

The sensor identification information given to is stored. The data storage unit 66 stores the number of times and the time when the human sensor 12a senses and reacts to the movement of a person as a response result.
In addition, since the structure of human sensor 12b-12f is the same structure as human sensor 12a, description is abbreviate | omitted.

Next, with reference to the flowchart of FIG. 5, the determination process of returning home in the life watching system according to the embodiment of the present invention will be described. In the following, a case will be described as an example in which it is determined whether a single person who has gone out has returned home based on the first return home determination logic.

Here, whether or not an elderly person living alone has gone out is determined based on the result of the sensor of the human sensor 12e installed at the entrance. That is, when it is determined that a single person living alone is staying at the entrance, and one minute has passed since the reaction of the human sensor 12e installed at the entrance disappeared, the single person living alone has gone out. Determined. For example, the human sensor 12e first reacts at 9: 4: 45 on March 10, 2001, and then the number of reactions is 8 times between 9: 5: 15 on March 10, 2001. Assume that it is determined that the elderly living alone is staying at the entrance. In this case, after the human sensor 12e reacts at 9:05:23 on March 10, 2001, 9: 6
If there is no response in any of the human sensors installed in the house 90 within 23 minutes, it is determined that the elderly living alone has gone out.

When an elderly person living alone goes out, the sensitive results from any of the human sensors 12a to 12f installed in the house 90 are received (step S10). That is, the human sensor 12a
The sensitivity result including the number of times and the time when the human motion is sensed and the response is transmitted from any one of -12 f, and the transmitted sensitivity result is received via the communication control unit 52. The human sensor 12a
In ~ 12f, the sensing result including the number of times when the person's movement is sensed and the reaction time and the house identification number stored in the data storage unit 66 and the sensor identification number are transmitted via the communication control unit 64 to the control device 11. Send to.

Next, the received sensitivity result is stored in the data storage unit 56 (step S11). In other words, the house identification number and sensor identification number received together with the sensitive result are compared with the house identification number and sensor identification number stored in the setting data storage unit 54, and in any place of any single elderly home. It is determined whether or not it is a sensitivity result of the installed human sensor and is stored in the data storage unit 56.
For example, the sensory sensor 12c received from the sensory sensor 12c, etc., and the sensory sensor 12c installed in the living room 93 of the house 90 reacted once at 11:10:12 on March 10, 2001. The data “56”, “March 10, 2001, 11:10:12, living room 93, once” is stored in the data storage unit 56.

Next, in step S10, it is determined whether or not a first predetermined time has elapsed after receiving the sensitive result from any of the human sensors 12a to 12f (step S12). For example, it is determined whether or not 30 seconds have elapsed since the response result transmitted from the human sensor 12c was received. If 30 seconds have not elapsed (step S12), the process returns to step S10, and 30
Sensitive results from the human sensors 12a to 12f are received until the second elapses.

When the first predetermined time has elapsed (step S12), based on the sensitivity result stored in the data storage unit 56, the number of reactions of the human sensor within the first predetermined time is the first predetermined time. It is determined whether or not the number of times has been reached (step S13). For example, it is determined whether or not the number of reactions of the human sensors 12a to 12f in the house 90 is 30 times or more within 30 seconds after the human sensor 12c installed in the living room 93 has reacted. .

When it is determined that the number of reactions of the human sensor within the first predetermined time is less than the first predetermined number (step S13), it is determined that the human sensor has malfunctioned (step S13).
14). For example, when the number of reactions of the human sensor 12c is “1” within 30 seconds after the human sensor 12c installed in the living room 93 of the house 90 has reacted, the human sensor 12c After the first response, no human sensor has reacted. Therefore, it is determined that the elderly sensor alone has not returned home, but the human sensor 12c has malfunctioned for some reason.

On the other hand, when it is determined that the number of reactions of the human sensor within the first predetermined time is greater than or equal to the first predetermined number of times (step S13), the person who first responded after going out alone It is determined whether or not the sensor is a human sensor 12e installed at the entrance (step S).
15).

When the human sensor 12e installed at the entrance reacts first (step S15)
It is determined that the elderly living alone has come home (step S16). That is, if any one of the human sensors 12a to 12f installed in the house 90 reacts twice or more within 30 seconds after the human sensor 12e reacts, the elderly living alone returns home. It is determined. When it is determined that the elderly living alone has returned home, a determination result indicating that the elderly living alone has returned home is stored in the data storage unit 56. In addition, the determination result stored in the data storage unit 56 is obtained from the communication control unit 5.
2 to the management server 20 via the management server 20 and the personal computer 30
And transmitted to a client terminal such as the mobile phone 31.

On the other hand, when a human sensor other than the human sensor 12e installed at the entrance reacts first (step S15), it is determined whether or not the elderly living alone has returned based on the second return determination logic. Is done. For example, the sensitivity result stored in the data storage unit 56 is “200”.
March 10, 1st, 11:10:12, Living room 93, 1 time "," March 10, 2001, 1
1 hour 10 minutes 42 seconds, living room 93, 2 times ". In this case, after the elderly living alone goes out, the human sensor 12c installed in the living room first reacts at 11:10:12, and then the human sensor 12c reacts once again at 11:10. It shows that the number of reactions in the minute 42 seconds is two. Therefore, 30 set as the first predetermined time.
The number of times of reaction that is set as the first predetermined number of times within 2 seconds is shown. However, since the person sensor 12c that reacted first was installed in the living room 93, whether the elderly living alone came home after judging whether the judgment result based on the first homecoming judgment logic was correct. In order to determine whether or not, return determination based on the second return determination logic is further performed.

Next, with reference to the flowchart of FIG. 6, the process which determines the return of the elderly living alone who is a monitoring subject based on a 2nd return determination logic is demonstrated.

First, after determining whether or not an elderly person living alone has come home based on the first return home determination logic, any one of the human sensors 12a to 12f installed in the house 90 is further provided. The sensory result is received (step S20), and the received sensory result is stored in the data storage unit 56 (step S21). The processes in step S20 and step S21 are steps S10 and S1 based on the first return determination logic shown in the flowchart of FIG.
Since the process is the same as that of No. 1, detailed description thereof is omitted.

Next, after the first predetermined time has elapsed, it is determined whether or not the second predetermined time has elapsed (step S22). For example, after receiving the sensitivity result transmitted from the human sensor 12c, 30
It is determined whether or not another 10 minutes have passed since the second passed. When 10 minutes have not elapsed (step S22), the process returns to step S20, and sensitivity results are received from the human sensors 12a to 12f until 10 minutes have elapsed.

When the second predetermined time has elapsed (step S22), based on the sensitivity result stored in the data storage unit 56, the number of reactions of the human sensor within the second predetermined time is the second predetermined time. It is determined whether or not the number of times has been exceeded (step S23). For example, it is determined whether or not the number of reactions of the human sensors 12a to 12f in the house 90 for 10 minutes is 5 times or more.

When it is determined that the number of reactions of the human sensor within the second predetermined time is equal to or greater than the second predetermined number (step S23), it is determined that the elderly living alone has come home (step S24). ). For example, the sensitivity results stored in the data storage unit 56 are “March 10, 2001, 11:10:12, living room 93, once”, “March 10, 2001, 11:10”.
42 minutes, living room 93, 2 times "," March 10, 2001, 11:20:42, living room 93
, 12 times ". According to this sensitive result, it is shown that there were 12 reactions by 11:20:42 after 10 minutes after the determination of returning home based on the first return home determination logic. . Therefore, during the 10 minutes set as the second predetermined time,
The number of reactions of 5 or more set as the second predetermined number is shown, and the determination result based on the first return home determination logic is correct, and it is determined that the elderly living alone has come home. When it is determined that the elderly living alone has come home, a determination result indicating that the elderly living alone has come home is stored in the data storage unit 56. The determination result stored in the data storage unit 56 is transmitted to the management server 20 via the communication control unit 52, and is transmitted from the management server 20 to client terminals such as the personal computer 30 and the mobile phone 31.

On the other hand, when it is determined that the number of reactions of the human sensor within the second predetermined time is less than the second predetermined number (step S23), it is determined that the whereabouts of the elderly living alone is unknown. (Step S25). That is, when the number of reactions of any of the human sensors 12a to 12f installed in the house 90 for 10 minutes is less than 5 after the first return home determination logic is performed. It is impossible to determine whether an elderly person living alone went out immediately after returning home, or whether the human sensor malfunctioned. Therefore, in this case, it is determined that the location of the elderly living alone in the house 90 is unknown.

For example, when the life of a single person living alone is monitored by the personal computer 30 installed in a care center or the like, even if it is determined that the place of the single person living alone is unknown, the personal computer 30 Information indicating that the elderly living alone is out is transmitted.

According to the life watching system according to the embodiment of the present invention, the time is set as the first predetermined time after any human sensor installed in the home of the person to be watched reacts.
Whether or not the person to be watched has come home can be determined based on whether or not the human sensor in the house has reacted more than once that is set as the first predetermined number of times within 0 seconds. Therefore, when the human sensor reacts based on the invasion of a small animal or the shake of the curtain or malfunctions, it is appropriately prevented that the person to be watched mistakenly determines that he / she has come home. It is possible to reliably determine whether or not the user has returned home.

Further, according to the life monitoring system according to the embodiment of the present invention, after the determination by the first return home determination logic, whether the determination result by the first return home determination logic is correct by the second return home determination logic. It is possible to determine whether or not the person being watched over has returned home. In other words, when it is determined that the person to be watched is going home due to the reaction of a human sensor installed at a place other than the entrance in the person to be watched for, 10 minutes is set as the second predetermined time. Between 5 times or more set as the second predetermined number of times,
When there is a reaction to the human sensor in the house, it is determined that the person being watched over has returned home. Therefore, it is possible to determine whether or not the watching target person has returned home with even higher accuracy.

Further, according to the life watching system according to the embodiment of the present invention, the second determination logic sets the second predetermined number of times within 10 minutes set as the second predetermined time. If there is no response to the human sensor in the house more than once, it is determined that the location of the person being watched over is unknown. That is, in a state where the state of the watching target person cannot be clearly determined, it is determined that the location of the watching target person is unknown, and the watching target person is out of the client terminal. Therefore, if it is not possible to determine that the person being watched has gone home, by displaying that the person being watched is going out, there is an abnormality in the person being watched even though the person being watched is not going home. It is possible to prevent erroneous determination such as occurrence.

In the life monitoring system according to the above-described embodiment, after the return home determination logic is performed, the return home determination logic is further used to determine the return home. It may be determined whether or not the person to be watched has come home only by the home return determination logic. That is, in the first return home determination logic, without judging whether the human sensor that first reacted after the person to be watched has gone out is installed in the house,
It may be determined whether or not the person to be watched has come home only based on whether or not a predetermined number of reactions have occurred within a predetermined time.

Further, in the life monitoring system according to the above-described embodiment, the first predetermined time is 30 seconds in the first return determination logic, but the time within 30 seconds, for example, 20 seconds, 25 seconds, etc. Also good.

The first predetermined time may be a time of 30 seconds or longer, for example, 35 seconds, 45 seconds, or the like. Moreover, although the 1st predetermined frequency | count is set to 2 times, it is good also as a frequency | count of 2 times or more, for example, 3 times, 4 times, etc.

Further, the second predetermined time is 10 minutes, but the second predetermined time may be a time within 10 minutes, such as 5 minutes, 7 minutes and 30 seconds, for example. The second predetermined time may be 10 minutes or longer, such as 12 minutes or 15 minutes. Furthermore, although the second predetermined number of times is five, the second predetermined number of times may be within five times such as three times or four times. As the second predetermined number of times,
It is good also as 5 times, such as 7 times and 8 times.

Further, in the life monitoring system according to the above-described embodiment, in the first return determination logic, after the person to be watched has gone out, whether or not the human sensor installed at the entrance first reacted is determined. Although it is determined whether or not the determination based on the return-to-home determination logic of 2 is performed, the determination may be made based on whether or not a human sensor installed in another place has reacted first. For example, in response to the life pattern of the person being watched over, such as a human sensor installed at the entrance, a human sensor installed in the living room, etc. It may be determined whether or not the determination based on the second return determination logic is performed based on the human sensor.

In addition, in the life monitoring system according to the above-described embodiment, when it is determined that the location of the person being watched over is unknown, it is confirmed that the elderly person living alone is going out to the personal computer 30. Although the information shown is transmitted, a warning e-mail may be transmitted. In other words, when it is determined that the location of the person being watched over is unknown, there is a possibility that the person being watched cannot move within the house 90, for example, has fallen within the house 90. Therefore, it is determined whether or not an abnormality has occurred based on the abnormality determination logic stored in the setting data storage unit 54. If it is determined that an abnormality has occurred, a warning e-mail is sent to warn that there is a possibility that an abnormality has occurred in the contact information at the time of abnormality stored in the setting data storage unit 54.
