[0025]

[Data Storage Format] FIG. 3 shows an example of a format in which data is recorded. In FIG. 3, bits 1 _b0 to
1 _b7 is from 0:00 to 7:00 as one bit 1 hour, bits 2 _b0 to 2 _b7 are from 8:00 to 15:00, and similarly bit 3
_{b0 to} 3 _b7 are allocated from 16:00 to 23:00, and are stored in 3 bytes as a time series in units of one hour 24 hours a day.

When each bit detects a sensor output, that is, when there is a life reaction, 1 is written to the bit corresponding to the time, and when there is no life reaction, it is kept at 0.

That is, the time period in which the bit is 1 indicates that the solitary elderly man took some action while at home,
The time period in which the bit is 0 indicates that the human body sensor was unable to detect a solitary elderly person, such as being out of bed, going to bed, or being unable to move due to an accident or illness.

Next, D0 of the date represents data of the day,
D-1 is the data area of the previous day, and similarly D-14 is the data area of 14 days ago. At the time when the data for one day has been written, that is, at 0:00, D0 to D-13 are D-1 to D-14. And the data of D-14 is deleted.

The data for 15 days is (3 bytes / 1 day) ×
15 days = 45 bytes.

The numerical value obtained by adding the number of bits D-1 to D-14 for each time period is the number of living reactions of the elderly living alone in that time period. Will be shown.

[0031]

[Method of calculating and judging the degree of pattern anomaly]
When the life reaction stops, that is, when bit 0 is determined in each time zone (every minute), the degree of abnormality is calculated from the past life reaction probability in the same time zone, and whether or not it exceeds a predetermined reference value Is determined by

When the time period of bit 0 is continuous, the degree of abnormality in the continuous time period is added, and when the difference of the life reaction probability in the adjacent time period is increased, it is added and decreased. If so, subtract it. This is a correction for reflecting the increase / decrease tendency of the past life pattern in the determination.

When the time zone of bit 1 occurs after the time zone of bit 0, a life reaction of the elderly living alone has been recognized. At that time, the pattern abnormality disappears, and the degree of abnormality is added. All data is cleared.

An example of the calculation will be described with reference to FIG.
1 when bit 0 is determined at 15:00 on D0 (the day)
The abnormality degree E16 at the time of 6:00 is as follows: P15 = 4/14 where P15 is the life reaction probability in the time zone of 15:00. Here, the numerator is D-1 to D-14 in the time zone of 15:00
The denominator is the number of days in the sum of bit 1 of

Next, since the bit is 1 in the time zone of 14:00, there is no correction, and E16 = P15 = 4/14.

Next, the abnormality degree E17 at 17:00
Is P16 = 6/14, where P16 is the life reaction probability as described above.

Further, since the bit 0 is continuous at 15:00 and 16:00, the difference in the life reaction probability is corrected, and E17 = E16 + P16 + (P16-P15) = (4/14) + (6/14) + [(6/14)-(4/14)] = 12/14.

Similarly, the degree of abnormality E1 at 18:00
8 is E18 = E17 + P17 + (P17-P16) = (12/14) + (11/14) + [(11/14)-(6/14)] = 28/14

Similarly, the degree of abnormality E1 at 19:00
9 is E19 = E18 + P18 + (P18-P17) = (28/14) + (13/14) + [(13/14)-(11/14)] = 43/14, and the reference value K is now set to 3. If you were

E19> K, and the automatic notification is started at this time.

Formulas for obtaining the degree of abnormality from the above examples are summarized as follows. _{E n = E n-1 +} P n-1 + (P n-1 -P n-2) where, _{E n} is the degree of abnormality E _n-1 at the 00 minute time n is in the 00-minute time (n-1) The degree of abnormality P _n-1 is the life reaction probability at the time of (n-1) P _n-2 is the life reaction probability at the time of (n-2)

The reference value K can be selected and set in the range of 2 to 5 according to the lifestyle of the elderly living alone.

【motion】

The operation of the entire apparatus for reporting abnormalities of the elderly living alone according to the present invention will be described with reference to the flowcharts of FIGS.

The CPU 11 of FIG. 2 starts operating when power is supplied to the power supply unit 27. First, in step S1 of FIG. 3, it is determined whether or not the telephone number of the notification destination is set in the EP2ROM 22 of FIG. The process proceeds to step S5 if the setting has been completed. If not, the process branches to step S2 and outputs a setting request message.

Next, in S3 of FIG. 4, the telephone number of the report destination and others are read by dialing the telephone.
The program proceeds to step S4 to check whether the setting is completed. If the setting is completed, the process proceeds to step S5.
Return to Step 2 and set again.

In the state where the setting has been completed, the emergency operation switch input in step S5 in FIG. 4 is read, and if it is determined in step S6 that the switch has been pressed, the process branches to the automatic notification process in step S28. Step S
It proceeds to the sensor input process of No. 7. In the sensor input process S7, the input process of both the infrared sensor 13 of FIG. 2 and the external interface 15 is performed. If there is no sensor input in step S8, the process proceeds to step S11. If there is, step S
The process branches to 9 to read the time from the RTC 24, sets the bit of the corresponding time zone in the life pattern data storage unit to 1, and proceeds to step S11.

In step S11, the time is read from the RTC 24 in FIG. 2 and in step S12 it is checked whether the time is 0:00. If they match, the flow branches to step S15.
If not, the process proceeds to step S13, and in step S13,
It is checked whether it is n: 00: 00 (n is 1.2... 23), and if they match, the flow branches to step S17, and if not, the flow proceeds to step S14.

In step S14, if the time coincides with the regular report time, the process branches to step S28 to perform regular report. If not, the process returns to step S5.

Branching from the above step S12, in step S15, the life pattern data is advanced by one day.
In the next step S16, all bits corresponding to the time zone from 0:00 to 23:00 are cleared to 0 to prepare for the subsequent data writing.

Step S16 and the aforementioned step S13
In step S17, the bit in the time zone at (n-1) is read, and in step S18, the bit is set to 1 or 0.
Check whether or not.

When the bit is 1, it indicates that the living alone of the elderly person has been living at least within the past hour. In the next step S19, the area E for storing the degree of pattern abnormality is cleared to 0, and the process returns to step S5. .

If the bit is 0 in step S18, the flow branches to step S20 because no living activity has been detected within the past hour.

In step S20, the bit at (n-2), that is, the time zone two hours before the present time, is read, and at step S21, it is checked whether the bit is 1 or 0.

If the bit is 1, it means that there was no life reaction in the time zone one hour before the present time.
At 22, the life reaction probability P _n-1 at the time (n-1) is calculated based on the above _- described calculation method, and is stored in the pattern abnormality degree E at step S23, and the process proceeds to step S27.

If the bit is 0 in step S21,
The process branches to step S24 in order to indicate that the living response of the solitary elderly has been continuously lost at least since (n-2) time. In step S24, the same calculation as in step S22 described above is performed, and the process proceeds to step S25, where (n-2)
The life reaction probability at the time P _n−2 is calculated.

Next, in step S26, the pattern abnormal degree E at the present time is calculated from the life reaction probability in each time zone obtained in step S24 and step S25 by using the above-mentioned pattern abnormal degree calculation formula.

[0057] _{E n = E n-1 +} P n-1 + (P n-1 -
P _n−2 ), and the process proceeds to step S27.

In step S27, the aforementioned step S23 is performed.
And calculated at step S26, the process returns to step S5 if it does not exceed the reference value is compared with a reference value K a second abnormality degree E _n, if it exceeds the reference value, vital reaction of elderly people living alone is in the past It is determined that the abnormality is abnormal in comparison with the life pattern, and the process proceeds to step S28 to perform an automatic notification process. This automatically dials a preset telephone number and sends a voice message indicating that the abnormality is abnormal. If the destination is busy or does not answer the call, step S2
In step 9, it is checked whether the notification has been completed. If the notification has not been completed, the process returns to step S28 to perform the notification process again. If the notification has been completed, the process returns to step S5.
