In FIG. 1, reference numeral 1a designates a house of an independent person who is cared for by the living behavior monitoring apparatus, and 11 is a person detecting apparatus, for example, in the form of a mat, which is installed in the house 1a of an independent person. The person detecting devices 11 are installed in a distributed manner, for example, in the vicinity of a plurality of entrances and exits of the room of the independent house 1a, and the terminal recording communication device 12 and the telephone 13 are installed in the independent house 1a.

In this embodiment, the human detection device 11 is installed in the living room,
The terminal, recording and communication device 12 and telephone 13 are installed at the entrances and exits of the bedroom, kitchen, toilet, and dressing room, respectively.

Reference numeral 18 denotes a step count measuring device for measuring the number of steps carried by a carrier, which is carried by a single person who is being cared for.

As shown in FIG. 2, the human detection device 11 includes, for example, a pressure sensor section 21 for detecting the passage of a person by stepping on it, and a switch circuit section 22 for converting a contact signal based on a pressure change. The signal line connecting portion 23 for transmitting the signal to the terminal recording / communication device 12 as shown in FIG. 3 forms a groove.

The switch circuit section 22 outputs a load signal as a level signal when a single person steps on and passes through the person detecting device 11 such as a care mat, and outputs a load change as a pulse signal. From these signals, it is possible to identify whether, for example, a luggage or the like is placed on the human detection device 11 or whether an independent person has stepped on when passing.

The step counting device 18 is, as shown in FIG.
The number of steps measured by the pedometer measuring unit 41 is input to the control circuit unit 43. 42 is a timer circuit unit that outputs a signal to the control circuit unit 43 when a certain period of time has passed. The control circuit unit 43 drives the wireless transmission circuit unit 44 by the signal input from the timer circuit unit 42 at every certain period of time. The step count data measured by the total measurement unit 41 is wirelessly transmitted.

Reference numeral 12 denotes a terminal recording / communication device, which sends a signal from a person detecting device 11 for detecting whether a single person is passing or staying as a change amount via a telephone 13 and a telephone line 19 to a single person's house. The data is transmitted to the center device 17 connected to 1a.

The terminal recording / communication device 12 is shown in FIG.
As shown in FIG. 3, the receiving unit 31 that receives the signal from the human detection device 11, the wireless receiving unit 35 that receives the step count data from the step count measuring device 18, and the two types of signals are converted into time series data. A data collection unit 32 to collect,
Occurrence location is determined from the signal of the time-series data from the human detection device 11, and the relationship between the past situation of the presence location and the next presence location is set by applying the probability model of quantification 2 class. Learned a certain period of time, recognize and judge daily living behavior patterns by using the probabilistic model, and from the signal of the time-series data from the step counting device 18, the presence position of the room by the signal of the human detection device 11 is detected. Time series data is analyzed, and if there is a move to the room, check the time series data of the step count data of the single person, and if the number of steps is extremely smaller than usual, there was no move to the room The life rhythm diagnosis unit 33 is configured to perform the processing described above, and the transmission unit 34 that transmits the diagnosis result diagnosed by the life rhythm diagnosis unit 33 to the care support center.

The information accumulated in the data collecting section 32 is processed by the life rhythm diagnosis section 33, and the diagnosis result is periodically transmitted to the center device 17 on the side of the care support center.

On the side of the care center, a care worker who is resident can comprehensively judge the change in the health condition displayed on the display unit 16 through the monitor unit 15 and judge whether or not there is an abnormality in the lonely person.

The living behavior monitoring method, which is an algorithm of the living rhythm diagnosis unit 33, evaluates the progress of the place in the room, that is, the living behavior pattern, by applying the quantification method 2 of the statistical analysis method. Quantification type 2 is a mathematical model that expresses the factors and results of qualitative states. For details, refer to Asakura Shoten, Shinsuke Muto, “Statistical Analysis Handbook”.

For the sake of explanation, time-series data of the place of residence, for example, bedroom, living room, toilet, washroom, kitchen, living room,
Kitchen, ..., Am, ... A _-3 , A _-2 ,
It is represented by A _-1 , A ₀ , A ₁ , and A ₂ , and the subscripts indicate the order. About this time series data A- _m , ... A- ₃ , A- ₂ ,
A _-1 as a factor, A ₀ as a result, then A _{-m + 1} , ...
_{A -3, A -2, A -1} , factors A _0, it is shifted one by one one as a result of A _1, a mathematical model that represents the relationship between the elapsed and the next occupancy location past occupancy location , Build from the past data of each individual.

When the matrix of factors is A, the resulting vector is B, and the weighting coefficient vector connecting these relationships is a, this mathematical model is expressed by the mathematical expression (1). A a
= B Numerical Expression (1) The time-series data of the above-mentioned occupancy place is applied to this mathematical model by shifting one by one, and the weighting coefficient vector a is calculated. By multiplying a predetermined number of time-series data of past occupancy locations by this weighting coefficient vector, the next moving occupancy location is estimated.

In the above mathematical model construction, in consideration of the fact that the activities of daily life start from getting up, the bedroom does not come and go during sleep, but if the person stays in the bedroom for a certain time or longer,
Treat it as if you were in the bedroom multiple times in a row. Also, like meals, laundry, and dissolution, the probability of staying in a particular room increases depending on the time of day, so time is included in one of the factors.

The daily living behavior pattern is determined by multiplying the time-series data of the actual occupancy place by the weighting coefficient vector to posit the next occupancy position, and whether it coincides with the actual next occupancy position. Compare whether or not. Next, using the time-series data of the occupancy location including the latest occupancy location, the next occupancy location is further estimated, and similarly, it is compared with the actual next occupancy location.

In this way, the estimated occupancy location and the actual occupancy location are sequentially compared in this manner. If there is a large number of coincidences in a day, there is no abnormality, and if there are a small number of coincidences, the living behavior pattern is higher than usual. Judge that it is disordered.

As described above, instantaneous information (place, time) obtained by stepping on the care mat of the human detecting device 11, history information (number of times / time, required time) for each care mat, history of a plurality of care mats. From the information, life behavior patterns such as getting up / sleeping time and walking distance are derived. By monitoring the life behavior pattern for a predetermined period,
It becomes possible to recognize and discriminate the change of living condition and health condition of a single person.

For example, since the daily changes in bedtime and wake-up time, whether or not the toilet is used and changes in the number of times, etc. are directly related to the health condition before the person is notified that he / she is sick. The care support center side can detect such changes in health in advance, and can take appropriate measures such as providing information to care and medical institutions.

Further, the health condition of a lonely person is not only physical, but mental changes also appear in life behavior patterns during bedtime and wake-up time (although this is not the case for the elderly,
According to Yoshihiko Chiba, Kiyohisa Takahashi, and Asakura Shoten, "Time Biology Handbook", in the case of bedtime and waking up, a normal child usually has the same bedtime.
It is known that autistic children have a significant time to go to bed and wake up. From this, psychological care will also be possible at the care support center side.

Further, when there is a visitor in the house of a single person and the visitor steps on the care mat of the human detection device 11 installed in the home, when the signal from the mat-shaped human detection device is converted. Although the detection signal of the visitor is added to the series data, the time-series data of the walking data of the pedometer carried by the solitary person is compared with the room-to-room movement data obtained from the care mat, and the room-to-room data is compared. If the number of walks is extremely small despite moving to, it is possible to determine that the life rhythm diagnosis section has not moved, so it is possible to eliminate the disturbance of the life behavior pattern data obtained from the history information for each care mat. , It is possible to detect an abnormal living condition or a change in health condition of a single person at an early stage without misrecognizing or misidentifying.

[0033]

As described above, according to the present invention, even if there is a visitor in the house of a single person and the detection signal of the visitor is added to the time-series data from the mat-like person detecting device, the single person can carry it. By making corrections from the time-series data from the pedometer, it is possible to prevent it from being recognized as an erroneous living behavior pattern, and it is possible for the center side to easily grasp the changes in the living condition and health condition of an independent person. , It becomes possible to judge whether there is any abnormality before the solitary person becomes important.
