DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for automatically observing the living conditions of an elderly person living alone and, when an abnormality or a precursor to the occurrence of an abnormality is detected, automatically notifies a predetermined contact to that effect. The present invention relates to a highly reliable safety confirmation and notification system having a self-diagnosis function.

[0002]

2. Description of the Related Art A conventional safety confirmation system for an elderly person living alone is an active direct report from an elderly person who is an observer, or an automatic report after an abnormality has occurred by monitoring a partial behavior of the observer with a simple sensor. However, there has been no high-reliability type system that has a function to detect a precursor of an abnormality before it becomes important or to have a self-diagnosis function.

[0003]

DISCLOSURE OF THE INVENTION The present invention monitors the life of an elderly person living alone without being conscious of the elderly, and if any disturbance occurs in the life of the elderly, it is used as a precursor to the occurrence of an emergency. Or to provide a reliable, small, and inexpensive safety confirmation / reporting system that promptly reports to a designated reporting destination and promptly responds that there is a possibility that an abnormality has occurred in the operation of the system. is there.

[0004]

[MEANS FOR SOLVING THE PROBLEMS] The entire living space of an elderly living alone is divided into several sections, and for each of a plurality of selected small spaces in the divided small space (for example, a room), an elderly living alone in the small space is divided into several small spaces. Install the best sensor in the best place for detecting life reaction. This sensor monitors whether or not the observer is normally working in the small space.For example, for a living room, the observer is walking or sitting on a mat incorporating a pressure sensor. A mat sensor that detects a person's presence and makes it a living response, an acoustic sensor that detects a living response based on the presence or absence of water noise in the toilet, and a seat switch output that detects whether or not the user is sitting on the toilet seat for a toilet A seating sensor that uses the signal as a living response signal, and a pressure sensor built into the pillow for the bedroom, using the pillow to determine whether or not the subject is sleeping normally based on the head movement of the subject sleeping Sleep sensor to know
Etc.

The life response signals, which are the outputs of the sensors, are sent to a system control unit, where the output history is stored for each sensor. The stored life response signal output history is constantly compared with a normal life response signal output pattern that is individually set in advance, and when the life deviation deviates from the normal pattern, the life of the subject may not be normal. To the designated report destination.
In this case, not only the information that the life state of the subject is not normal but also the life response signal output history data indicating the abnormality is reported, so that the report destination can know the contents of the abnormality. If the life response signal output history deviates from the normal pattern, the cause may be that the operation of the system is not normal. Therefore, the fact and the data (life response signal output history, etc.) related thereto are also notified. Report first.

It is also possible to detect an abnormality in the life of the subject or an abnormality in the system from the logical relationship between a plurality of life response signal output histories. For example, when living response sensors are provided in three places, a living room, a washroom, and a corridor between the living room and the washroom, when the frequency of the living response signal output in the corridor is less than the frequency of the living response signal output in the living room and the washroom, The detection sensitivity of the life response sensor in the corridor's life reaction sensor is low, or the detection sensitivity of the life response sensor in the living room or the bathroom is too sensitive.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

In FIG. 1, reference numeral 11 denotes a living response sensor installed in a specific small space in a group of small spaces (rooms, etc.) obtained by dividing a living space of an elderly person living alone into several living spaces.
It monitors the change of a specific physical quantity due to the living activity of the elderly living alone in the specific small space where the life reaction sensor 11 is installed, and when the fluctuation exceeds a certain amount within a certain time, a life reaction signal is determined to be present. Output. 12
Is a wireless device that uses a weak electric power to transmit a life response signal, which is an output signal of the life response sensor 11, to a system control unit 2 described below. The life response sensor 11 and the wireless device 12 constitute the sensor unit 1. .

Reference numeral 21 denotes a wireless device using weak electric power for receiving a life response signal from the wireless device 12, and 22 sequentially stores a life response signal output from the life response sensor 11, and stores the stored life response signal. The output history is always compared with the normal life response signal pattern P1 set in advance.
It is assumed that the life of the observer is not normal, and a voice signal and data stored in the telephone
The notification is sent to the report destination terminal unit 3 via the control unit, and the output history of the stored life response signal is compared with a preset normal pattern P2 of the output history. , The controller 23 that reports to the reporting destination terminal that there is a possibility that there is an abnormality in the wireless device 12 or the wireless device 21 by using an audio signal and data stored therein. And a mobile phone capable of voice and data communication for notifying the information to the notification destination terminal 3 described later.
2 and the mobile phone 23 constitute the system control unit 2 for the elderly living alone.

Reference numeral 31 denotes a portable telephone for receiving voice or data from the portable telephone 23. Reference numeral 32 denotes an abnormal state of the life pattern of the observer sent from the system control unit 2 or an abnormal state of the system. This is a display device for displaying data and the like, and the portable telephone 31 and the display device 32 constitute the report destination terminal unit 3. When the display function of the mobile phone 31 can be substituted for the display device 32, the display device 32 becomes unnecessary.

Next, the operation will be described with reference to FIG. In the solitary elderly person safety confirmation and notification system configured as described above, for example, a toilet as a specific small space, as a life response sensor to be installed in the specific small space, is usually in an OFF state, and the observer is sitting on the toilet seat. Assume a seating sensor using a switch that is turned on for a while. (See Fig. 2-a)

Here, in a state where the elderly person living alone lives normally, the toilet seat use frequency NX is N1 to N2 times during a fixed time TD (for example, 24 hours), and the time TX when sitting on the toilet seat is TX. Is T1 to T2 within a certain time. These N1 to N2 and T1 to T2 together form a normal life response signal pattern P1. (See FIGS. 2-a and b)

The toilet seat frequency NX or the toilet seating time TX is constantly monitored by the system control unit 2, and when they deviate from the normal frequency range N1 to N2 or the time T1 to T2 (TD (FIG. 2A)). 2) and TX2 in FIG.
), The elderly living alone are not in an emergency, but are in an abnormal state, such as diarrhea or constipation, and notify the parent By doing so, it becomes possible to deal with a solitary elderly before it becomes an emergency.

When the use of the toilet seat is interrupted at a certain point in time, or when the seating time is abnormally long, an emergency report is issued assuming that there is a possibility that an emergency has occurred to the subject. Alternatively, in the above case, there is no abnormality in the life of the elderly living alone, and there is a possibility that there is an abnormality in the system side, for example, the seating sensor. Is also possible.

In FIG. 1, only one sensor unit is provided. However, by installing the sensor unit in another small space as required, the accuracy of safety confirmation can be improved. In this case, however, the memory of the life response signal output history corresponding to the number of sensor units installed in the controller 22 and the setting and comparison of normal life response history patterns P1 and P2 corresponding to the life response sensor are provided. Needless to say, functions are required.

[0016]
