Abstract

PROBLEM TO BE SOLVED: To provide a life watching device which notifies a carer and/or a family member of the everyday sleep time of a single person being watched, and any occurrence of an emergency such as absence of vital reaction for a long time.SOLUTION: One human sensor is installed in an area such as a living room or a kitchen of a single target person to be watched where the person spends a long time during a day. A total number of human sensor reactions in a certain period is compared with threshold values for events, such as the start or finish of sleep or absence of vital reaction for a long time, to determine that the person has started or finished sleeping or has shown no vital reaction for a long time. Information on a sleeping time or an emergency is transmitted to a server or a client such as a personal computer and a smartphone.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a daily life monitoring apparatus for reporting to a caregiver and a family about the daily sleep time of a single person to be watched over and the occurrence of an emergency without a long life response.

  In Japan, the proportion of elderly people has increased with the years, and the number of single elderly people has increased rapidly due to the progress of the nuclear family. Therefore, caregivers and family members are requesting provision of a life monitoring device that reports sleep time leading to early detection of poor physical condition of single elderly people and emergency information when there is no life reaction.

  “Activity state determination device, watching support system, and activity state determination method” described in Japanese Patent No. 418584 analyzes the activity state of the subject by the transition of the body motion amount absolute value indicating the body motion amount data and the body motion amount difference value. There is a system to do.

  Japanese Patent Laid-Open No. 2003-102704 discloses a system that uses a plurality of human sensors that are provided in various places including a bedroom of a person being watched over and that are sensitive to the movement of a human body.

Japanese Patent No. 418584 JP 2003-102704 A

  Even if you go to bed on a tropical night, you may not be able to fall asleep and finally fall asleep. Therefore, you may get up late, or you may have physical problems such as being unable to sleep even if you go to bed due to body pain. In such a case, the sleep time is different from normal. Knowing the daily sleeping hours, you can quickly find abnormal sleeping hours and take countermeasures. Therefore, it is the first problem of the present invention to convey the daily sleeping hours to caregivers and family members.

  In addition, a single person may spend a long time without moving because of a fall or poor physical condition. In such a case, it is a second problem of the present invention to detect that there is no life reaction for a long time and promptly make an emergency call to a caregiver or family member.

  When using a personal life monitoring device like a case where an urban son watches a mother in the country, it is desirable that the system is easy to install and low in cost. The life monitoring apparatus that realizes these is the third problem of the present invention.

  In Patent Document 1, a personal computer is necessary at a place where a human sensor is located, and there are many setting items, and there are many problems in that the system is difficult and expensive for individuals to use. In the case of this system, when going to the toilet at night, which is common for elderly people, both the absolute value of the body motion amount and the difference value of the body motion amount are large, so it is determined that the user gets up. However, in general, it is not uncommon for an elderly person to go to the toilet at night, and when the toilet is finished, it is normal to go to sleep again and sleep until morning.

  In Patent Document 2, since a system is configured using many human sensors, it is difficult to put it to practical use in terms of high cost.

As a person's life pattern, “Wake up in the bedroom, go to the toilet, spend in the living room, have breakfast in the kitchen, spend in the living room, go out, go home, have lunch in the kitchen, spend in the living room, go out, go home It is assumed that the students have dinner in the kitchen, spend in the living room, go to the toilet, sleep in the bedroom, and go to the toilet several times during this time, or take actions such as taking a bath. For this reason, it is possible to observe a daily life pattern by placing a human sensor in a living room with a long residence time.
For example, if there is no human sensor response for a certain period of time at night, it is determined to be sleep, and if there is no human sensor response for a long time, it can be determined that an emergency has occurred.

  In the present invention, in order to have two functions of calculating the sleep time by the response of one human sensor and detecting that there is no life reaction for a long time, it is not necessary to sleep in one place in a day. A life monitoring device will be installed in a place where it takes a long time to stay. Since the detection area of the human sensor of the life monitoring device has a conical shape of about 90 degrees from the center of the human sensor, it satisfies the requirement that there is no bedding within this range, and the time to stay in the day Long rooms are suitable for the living room.

  The sleep time for inferring health is not considered when taking a nap on the sofa or kotatsu in the living room, but covers the time to sleep in the bed at night. As the aging progresses, the toilet becomes closer and more people get up for the toilet during sleep at night. However, in order to go to sleep again, do not end the sleep time when you get up for this toilet. You have to measure your sleep time until you wake up in the morning. In addition, by monitoring the number of times of getting up to go to the toilet at night, it is also possible to predict the state of poor physical condition.

  The measured sleep time is sent by e-mail with the sleep time as a sentence and a graph shown in FIG. If there is no reaction for 12 hours, an emergency mail is immediately sent.

  The feature of the present invention is that it is possible to measure the sleep time of a single person at night only by installing a life monitoring device equipped with a human sensor in one place, and when there is no life reaction for a long time due to an accident or poor physical condition And to inform caregivers and family members.

It is a schematic system block diagram of the life watching apparatus of this invention. It is a top view which shows the arrangement | positioning state of the human sensitive sensor at the time of installing in 2DK floor plan of the said life monitoring apparatus. It is a top view which shows the arrangement | positioning state of the human sensitive sensor at the time of installing in 1DK floor plan of the said life watching apparatus. It is an activity condition graph of the life monitoring device when installed in the floor plan of the 2DK It is a flowchart of a human sensitive sensor reaction accumulation process. It is a flowchart of a sleep time calculation process.

  The life monitoring device of the present invention is composed of a human sensor, a processing device having a function of transmitting information to the server or a client such as a personal computer or a smartphone, and the response count and analysis result of the human sensor. One motion sensor detection area is installed in a place where the person stays at the target person's house for many hours in the day and does not include the sleeping area, and the processing device scans the motion sensor at time intervals that can track the movement of the person. If there is a human sensor response, add the number of human sensor responses, accumulate the number of human sensor responses in a fixed period of several minutes to several tens of minutes, and start sleep, end sleep, In a cycle for judging an event such as no long time, the cumulative number of human sensor responses accumulated for each time interval set for each event is compared with a threshold value set for each event, Start of sleep Determine the event such as the end of sleep, the sleep time, and the lack of life response, and identify the target person's home or individual by watching the graph plotting the accumulated value of the number of human sensor responses accumulated at regular intervals on the corresponding time axis It has a function to transmit with information including character information that can be made.

  Further, it is desirable that the processing apparatus is provided with at least one of a LAN terminal for connecting to a network, a broadband modem, a WIFI slave unit, or a USB terminal for connecting a broadband modem.

  FIG. 2 is a plan view when the life watching apparatus 10 of the present invention is installed in the 2DK floor plan used by many single persons. Since the human sensor detection area 13 of the life monitoring device 10 has a conical detection area of about 90 degrees, the life monitoring device 10 is installed at the corner of the living room 3 that can cover the entrance and exit of the bedroom 11 and the whole living room 3. .

  If the human sensor 11 is placed in the bedroom 1, it is easy to calculate the sleeping time, but since the time spent outside the bedroom 1 is long, it can be separated from the case where the patient cannot move due to an accident or poor physical condition. Since it cannot do, the method of installing the human sensor 11 in the place where a lot of time of the day is spent like the living room 3 is good.

  In this embodiment, the life monitoring device 10 is installed in the living room 3, but depending on the floor plan, the kitchen 2 or other places may be placed if the staying time in the kitchen 2 or other places is long.

  It is common for the elderly to go to the toilet 4 at night. In that case, the elderly person goes through the living room 3 and the kitchen 2 to add to the toilet 4, and then returns to the bedroom 1 through the living room 3 and continues to sleep. This series of operations is within 30 minutes at the longest, and the threshold for determining the difference from the end of sleep is estimated from the total number of responses of the human sensor 11 when the toilet 4 is added.

  FIG. 4 is a graph in which the vertical axis represents the number of reactions of the human sensor 11 and the horizontal axis represents a lapse of 72 hours. The graph data includes the number of reactions from the human sensor 11 every 5 minutes as one element. t1, t2, and t3 are nighttime sleep times, and t4 is a time spent in the toilet 4 at night. Assuming that the sleep time ends with the time when the user goes to the toilet 4, the sleep time differs greatly between the day when the user goes to the toilet 4 and the day when the user does not go to sleep. This is a normal range and not an abnormal situation. It is one of the features of the present invention that it is possible to distinguish between awakening in the morning and getting up when going to the toilet 4.

  FIG. 5 is a flowchart for calculating sleep time. The human sensor scan interval pause S41 in this embodiment is set to 0.5 seconds in order to reliably capture the movement of the human hand or head. When the human sensor 11 is turned on S42, the human sensor response The number is incremented by 1S43. The total time S44 is 5 minutes in this embodiment, and after accumulating the number of human sensor responses S45 every 5 minutes, the human sensor 11 is reset S46 and starts counting again. Cumulative calculation of the number of human sensor responses from the time T1 to the current time T1 of S47 is 60 minutes in this embodiment, and the number of human sensor responses accumulated 60 minutes before the current time is accumulated. If this value is 0, it is determined that there was no movement for 60 minutes and that the patient went to bed.

  The cumulative calculation S48 of the number of human sensor responses from the current time to the time T2 is a process for determining a difference between the time when the user goes to the toilet 4 and the time when the user wakes up. In this embodiment, T2 is set to one hour. The reason is that there is a clear difference in the cumulative number of human sensor responses when waking up in the toilet 4 and when waking up in the unit of one hour.

  FIG. 6 is a flowchart of the sleep time calculation process. The nighttime S30 does not consider napping or going out as sleep, so it is determined whether sleep is started or whether the sleep start time is set in S31. If sleep has not started, the cumulative response over time T1 <the sleep threshold S32 determines that the human sensor 11 has hardly reacted for a certain time T1, and determines whether or not he / she has gone to the bedroom and slept, sleep time = current Time-T1 time S33 sets sleep start time.

  T2 time sensor response cumulative is larger than the alarm threshold or S34 threshold is larger than the one hour human sensor 11 cumulative when the toilet 4 is woken, and smaller than the one hour human sensor cumulative total when waking up Is a threshold value. This threshold value has an advantage that it can be used as a standard value because individual differences are unlikely to occur. After setting sleep completion time = current time−T2 time S35, sleep time = sleep completion time−sleep start time S36 is set.

  The sleep threshold described above is a sensor response cumulative value that can be determined to have entered into sleep without a sensor response for a certain period of time, and the wake-up threshold is a sensor response cumulative value that can be determined that sleep has been completed in the morning.

  The embodiment of FIG. 2 is a plan view when the life watching apparatus 10 is installed in the layout of 1DK. In this case, since the kitchen 2 and the living room 3 enter the sensing area of the human sensor 11, the time for grasping the behavior of a single person is longer than in the case of the first embodiment, so that the sleep time can be accurately determined. If you go to 4, you can't count the number of times you went to the toilet 4 during sleep because you don't go through the living room 3.

Recent technological advances have greatly improved the capacity of the processing apparatus, and in addition, miniaturization has been realized. For this reason, it has become possible to perform advanced processing that has been impossible in the past with a processing device. For example, the processing device has a WIFI function and can be connected to a broadband modem that can be connected to the Internet, so that a low-cost and high-performance life monitoring device can be realized.
Since the number of single elderly people will increase in the future, it is expected that the demand for cheap and high-performance life monitoring devices as in the present invention will increase.
