Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a behavior determining apparatus for determining whether or not a pattern relating to a behavior of a predetermined subject substantially matches the actual behavior of the subject, and a behavior of the subject. The present invention relates to a care system for accurately identifying a subject and providing care to the subject, a care house equipped with the care system, and a program recording medium.

[0002]

2. Description of the Related Art As a conventional behavior judging device, there is, for example, a device for judging the behavior of an elderly person living alone. Specifically, the number and frequency of pressing the use button of a jar pot used in a house where a solitary elderly person lives is continuously detected for a predetermined period of time, such as one month, and the average daily usage is monitored. , Recorded in advance as a jar pot movement pattern, and used the jar pot of a solitary elderly person after the recording, in other words, detected the jar pot movement, and compared the detected jar pot movement with the recorded pattern Then, there is a device for determining whether or not the operation of the jar pot substantially matches the pattern. The device determines the behavior of the elderly living alone based on the determination result.For example, if the jar is not actually used at the time when the jar is used in the pattern,
A warning that the solitary elderly person is sick is reported to the management center connected to the behavior determination device. Further, as another conventional behavior determination device, as compared with the operation of the above-mentioned jar pot and the pattern, by comparing the usage state and the pattern of tap water detected by the sensor attached to the water meter, Some devices determine the behavior of a solitary elderly person by determining whether the usage status substantially matches the pattern.

Further, the operation is similar to that of an apparatus which compares the operation of a device such as a jar pot with a pattern to determine whether or not the operation of the device substantially matches the pattern, but detects the operation of the device. Instead, there is an action determination device that directly detects the action of a person and determines whether the action of the person substantially matches a pattern recorded in advance. As means for directly detecting human behavior, for example, a pyroelectric infrared sensor that is installed in a room where a resident in a house frequently passes or a ceiling portion of a corridor and detects that a person is living is used. There is a human sensor.

[0004]

However, a conventional behavior determination device that detects the operation of a device such as a jar pot or a water meter is difficult to determine a person's living situation in real time. Even if an abnormality occurs in the target person, a certain period of time, such as one day, is required until it is determined that the abnormality has occurred.

[0005] In addition, the pyroelectric infrared sensor also responds to the movement of a small animal such as a dog or a cat, such as a curtain that shakes when the window is opened and the air flows, so that the conventional behavior determination device is not suitable for humans. Behavior cannot be detected accurately.

Further, as a means for directly detecting the behavior of a person different from the pyroelectric infrared sensor, there is a bed sensor for detecting whether or not a person is in a bed. When the user goes to the kitchen and toilet and returns to the bed, it is detected by a pyroelectric infrared sensor or an on-bed sensor that the person once left the bed at midnight and went to the kitchen and toilet. However, the conventional behavior determination device is
It is not possible to determine whether a person went to the kitchen, opened the refrigerator door, drank a drink, and then went to the toilet because the throat was dry, or left the bed without meaning and went to the kitchen and the toilet. For example, an elderly person may have dementia if he or she acts meaninglessly, but the conventional behavior determination device cannot be used to detect the possibility of dementia.

An object of the present invention is to provide an action judging device for more accurately detecting an action of a target person in consideration of the above-mentioned problem.

It is another object of the present invention to provide a care system for accurately specifying the behavior of a subject and providing care to the subject. Another object of the present invention is to provide a care home provided with the care system.

When the CO ₂ concentration in the kitchen 14 measured by the air quality sensor 4 exceeds the predetermined threshold value, it is detected that the resident is in the kitchen 14, and this is detected by the recording unit 23.
It is recorded in. When a person is present in the kitchen 14, the CO ₂ concentration in the kitchen 14 increases.
The air quality sensor 4 can detect whether or not there is a person in the kitchen 14 by measuring the CO ₂ concentration in the kitchen 14. When a person cooks in the kitchen 14, the humidity, the CO ₂ concentration, and the volatile organic component concentration increase. Therefore, the air quality sensor 4 outputs all or one of the humidity, the CO ₂ concentration, and the volatile organic component concentration in the kitchen 14. It is also possible to detect whether or not there is a person in the kitchen 14 by measuring the section.

At 9:30 am, the infrared sensor 2 detects the movement of a person, and the occupant disappears from the image of the kitchen 14 taken by the CCD camera 1a. CO in kitchen 14
_{2 When the} concentration falls below the predetermined threshold,
Since the image of the living room 15 captured by the CD camera 1b includes the resident's figure, it is detected that the resident has left the kitchen 14 and has entered the living room 15, and this is detected by the recording means 23. It is recorded in. After that, from 9:30 to 11:00, the CCD camera 1b
Resident was included in the image of the living room 15 taken by the

This is the averaged pattern for August of August.

When the resident moves from the kitchen 14 to the living room 15 or from the living room 15 to the kitchen 14, the infrared sensor 2 detects the movement of a person. In this case, the infrared sensor 2 detects the movement of the person. Is output to the transmitting and receiving means 12. Then, the transmission / reception means 12 transmits an instruction for transmitting an identification number for identifying the person carrying the PIT 11 to the PIT 11 by a radio wave having high directivity in the limited space. . Upon receiving the instruction, the PIT 11
An identification number for identifying the resident being carried is transmitted by radio waves, and the transmission / reception means 12 identifies the person who has emitted the infrared ray detected by the infrared sensor 2 based on the identification number from the PIT 11. The identification specifies who is the resident who has moved from the kitchen 14 to the living room 15 or from the living room 15 to the kitchen 14.

Such a specifying method is used when a plurality of people live in one house, when a person who has moved from one of the adjacent rooms to the other is to be identified, and the adjacent room is used. Can be used to identify who moved from one side of the corridor to the other. In addition, in order to identify who moved from one of the adjacent room and the corridor to the other, for example, on the ceiling of the adjacent part of the room and the corridor, such as the transmitting and receiving means 12 described above, P
It is necessary to provide a means for identifying who has moved from one of the room and the corridor to the other based on the identification number from IT11.

Next, the first embodiment of the present invention after the first pattern and the second pattern are recorded on the recording means 23.
The operation of the behavior determination device will be described. For convenience of explanation, 199
The operation of the behavior determination device according to the first embodiment on July 22, 2009 and August 3, 2009 will be described.

The resident's actions on July 22 and August 3 were the CCD camera 1a and the CCD camera 1
b, detected by the infrared sensor 2, the on-bed sensor 3, the air quality sensor 4, the toilet sensor 5, and the PIT 11, and each detection data is input to the determination means 24 shown in FIG. Also, the P identified by the transmitting / receiving means 12
Information on the person carrying the IT 11 is also input to the determination means 24. In addition, on either day of July 22 or August 3,
Opening and closing operations of windows 19 and 20, ON / O of power supply of television 21
The FF operation and the opening / closing operation of the door of the refrigerator 22 are detected by the window opening / closing detecting means 6 and 7, the television power ON / OFF detecting means 8, and the refrigerator door opening / closing detecting means 9, respectively. Is input to

Next, the operation of the determination means 24 will be described with reference to the flowchart of FIG. The determining means 24 inputs the above-described respective detection data (step 1), and also inputs the first pattern and the second pattern recorded in the recording means 23 (step 2), and determines the resident's action and the window 1
Opening / closing operation of 9 and 20, ON / OFF of power supply of TV 21
It is determined whether the combination of the operation and each operation of opening and closing the door of the refrigerator 22 matches the first pattern or the second pattern within a predetermined time or within a predetermined action range (step). 3). Then, the judgment means 24
Outputs the determination result to the output means 25 (step 4).

To give a specific example, on July 22, for example, a resident is in bed 17 from 00:00 to 1:55, and leaves bed 17 at 1:55 am Assuming that the user goes to the toilet 18 and returns to the bed 17 at 2:05 am, the occupant's action in that case is detected by the occupancy sensor 3 and the toilet sensor 5 and input to the determination means 24. By the way, the behavior of the resident input to the determination means 24 and the behavior from midnight to 2:10 of the first pattern described with reference to FIG. 24 determines that the behavior of the resident substantially matches the behavior of the resident in the first pattern. Here, 02:00 on July 22
From time to 1:55, the window opening / closing detecting means 6 detects that the window 19 is closed, the window opening / closing detecting means 7 detects that the window 20 is closed, and turns on the television power.
The / OFF detection means 8 detects that the power of the television 21 is OFF, and the refrigerator door open / close detection means 9 detects that the door of the refrigerator 22 is closed. Actions, opening and closing operations of windows 19 and 20, ON / OFF operation of power supply of television 21, and refrigerator 22
It is determined that the combination of each of the operations of opening and closing the door substantially coincides with the first pattern, and the result of the determination is output to the output means 25. The output unit 25 outputs the determination result to the warning transmitting unit 26 and the notifying unit 27, and the combination of the resident's action and each operation of the windows 19 and 20, the television 21, and the door of the refrigerator 22, Since it is determined that they substantially match one pattern, the warning transmitting unit 26 and the notifying unit 27 do not output a warning.

Next, another specific example will be described. A case where the resident leaves the bed 17 at 6:00 am and does not open the window 19 on July 22 will be described. Then, it is assumed that the window 19 cannot be opened thereafter.
The behavior of the resident in that case is detected by the occupancy sensor 3 and input to the determination means 24. The opening / closing operation of the window 19 is detected by the window opening / closing detecting unit 6 and is determined by the determining unit 24.
Is input to The resident's action input to the determination means 24 matches the action after 6:00 am in the first pattern, but since the window 19 has not been opened, the actual opening and closing operation of the window 19 and the first The opening / closing operation of the window 19 in the pattern does not match. As a result, the determination unit 24 determines that the combination of the resident's action and the opening / closing operation of the window 19 does not substantially match the first pattern.

The judging means 24 outputs a judgment result that the combination of the resident's action and the opening / closing operation of the window 19 does not substantially match the first pattern.
Output to Then, the output unit 25 outputs the determination result to the warning transmitting unit 26 and the notifying unit 27, and also outputs the result to the speaker 13. The warning transmission means 26
A warning is transmitted by radio wave, and the PIT 11 receives the warning by radio wave, emits sound, vibration and light based on the warning, and notifies the warning to the carrier. In addition, the reporting means 27
A warning is output to a speaker located in a house different from the house of FIG. 1 and connected to the notification means 27 via a telephone line, and a warning sound is emitted. Also, the speaker 13
A warning sound is issued based on the determination result from the output unit 25.

As described above, since the PIT 11 and the speaker 13 give a warning, the resident can know that the actual behavior is different from the pattern recorded in the recording means 23 in advance. The resident other than the person can know that the behavior of the resident judged by the judging means 24 is abnormal. Further, according to the warning from the notifying means 27, the person living in a house different from the house in FIG.
4 can know that an unusual behavior has occurred in the behavior of the resident that has been determined. Therefore, if the notification means 27 and a speaker that emits a warning sound in accordance with the warning output by the notification means 27 are arranged in a two-family house, for example, the abnormality of an elderly man who usually stays alone alone quickly causes the elderly child to quickly notice the abnormality. You can know.

Conventionally, it has been detected that the resident has left the bed 17 and the opening / closing operation of the window 19 has been detected. However, the combination of the occupant's action and the operation of the window 19 operating in accordance with the action is detected. Since it was not determined whether the pattern substantially coincides with the pattern, the behavior of the resident after leaving the bed 17 was not specified more accurately. On the other hand, in the present embodiment, it is determined whether or not the combination of the resident's action and the operation of the window 19 and the pattern substantially match. Behavior is more accurately identified.
Thus, for example, the resident leaves bed 17 at 6:00 am and falls into the window 1
When the occupant 9 cannot be opened, the speaker 13 emits a warning sound. Can be taken quickly. In addition, a person living in a house different from the house shown in FIG. 1 can quickly perform the same treatment by the warning from the notification means 27.

The first data recorded in the recording means 23
In the pattern, as shown in FIG. 3, only “leaving from bed 17” detected by occupancy sensor 3 is described as the behavior of the person from 6:00 to 7:00, Alternatively, or in addition to its description, PIT
The data on the posture of the target occupant, which is detected by the gyro sensor, the acceleration sensor, and the angle sensor incorporated in the occupant 11, may be described. In this case, the determination unit 24 determines that the pattern including at least the data regarding the posture of the
It is determined whether or not the combination of the behavior of the resident detected by 11 and the operation of the device such as the window 19 substantially matches. Therefore, for example, from 6:00 to 7
If the data indicating that the resident falls away after leaving the bed 17 is not described in a part of the first pattern recorded in the recording means 23, If the resident falls away after leaving the bed 17 during the determination, the PIT 11 detects that the resident has fallen, and the determination means 24 determines that the resident's behavior does not match the pattern. The determination is made, and a warning is issued accordingly.

Further, another specific example will be described. 8
It is assumed that, for example, when a resident enters the kitchen 14 at 11:00 pm and opens the door of the refrigerator 22 on March 3 to start preparing for lunch, the physician becomes abnormal and falls down. The behavior of the occupant in that case is detected by the CCD camera 1a and the air quality sensor 4 and input to the determination means 24. Further, the opening / closing operation of the door of the refrigerator 22 is detected by the refrigerator door opening / closing detecting means 9 and inputted to the judging means 24. The behavior of the resident input to the determination means 24 substantially matches the behavior after 11 pm of the second pattern described with reference to FIG. 4, but the door of the refrigerator 22 remains open. Therefore, the actual opening / closing operation of the door does not match the opening / closing operation of the door in the second pattern. As a result, the determination unit 24 determines that the combination of the resident's action and the opening / closing operation of the door of the refrigerator 22 does not substantially match the second pattern.

Then, the determination means 24 outputs to the output means 25 a determination result that the combination of the resident's action and the opening / closing operation of the door of the refrigerator 22 does not substantially match the second pattern. The output unit 25 outputs the determination result to the warning transmitting unit 26 and the notifying unit 27, and also outputs the result to the speaker 13. The warning transmitting means 26 transmits a warning by radio waves, and the PIT 11 receives a warning by radio waves, emits voice, vibration and light based on the warning, and notifies the warning to the carrier. In addition, the reporting means 27
A warning is output to a speaker located in a house different from the house of FIG. 1 and connected to the notification means 27 via a telephone line, and a warning sound is emitted. Further, the speaker 13 emits a warning sound based on the determination result from the output unit 25.

As described above, since the PIT 11 and the speaker 13 give a warning, the other occupants may determine that the behavior of the occupant that has been judged by the judging means 24 is abnormal. You can know. In addition, due to the warning from the notification means 27, it may be that a person living in a house different from the house in FIG. You can know that.

The second means recorded in the recording means 23
As shown in FIG. 4, the pattern includes a person's behavior from 11:00 to 12:00 and the CCD camera 1 a and the air quality sensor 4.
Is described, but instead of or in addition to the description, it is detected by a gyro sensor, an acceleration sensor, and an angle sensor incorporated in the PIT 11. In addition, data on the posture of the resident as the target may be described. In this case, the determination unit 24 determines that the pattern including at least the data on the posture of the resident substantially matches the combination of the behavior of the resident detected by the PIT 11 and the operation of the device such as the door of the refrigerator 22. Is determined.
Therefore, for example, data indicating that the resident falls down as the behavior of the person from 11:00 to 12:00 is recorded in the recording unit 23.
Is not described in a part of the second pattern recorded in the PIT 11 and the resident falls down in the kitchen 14 at the time of the determination by the determination means 24, the PIT 11 detects that the resident has fallen. Therefore, the determination unit 24 determines that the behavior of the resident does not match the pattern, and a warning is issued accordingly.

As described above, the action determining apparatus according to the first embodiment of the present invention is designed to record the pattern of the combination of the action of the predetermined target person and the operation of the predetermined device, which is recorded in the recording means 23 in advance. It is possible to determine whether or not the actual combination of the behavior of the target person and the operation of the device substantially coincides with each other, and output the determination result. , Is also estimated earlier. Also, the subject himself / herself can know that he or she has acted differently from the pattern.

In the first embodiment described above, a case has been described in which each component of the behavior determination device is arranged at each place in a house, etc.
It is not limited that the device is arranged only in each place of the house, and may be arranged in, for example, a hospital or a nursing home. In this case, when the output unit 25 or the notifying unit 27 outputs the determination result to a management unit such as a nurse's room of the hospital, directly or through another device, the manager such as the nurse can determine the behavior of the target person. It can be grasped more accurately.

Although there are many subjects in hospitals, nursing homes, etc., each subject is provided with a unique resident, similar to the second transmitting / receiving means provided in the PIT 11 described above. Transmitting means for transmitting an identification number for identifying the resident by radio waves, or the above-mentioned PIT
When the user carries 11, it is specified who the person detected by the detecting means such as an infrared sensor that detects the behavior of the person is. In addition, for example, when the target person is living alone and each component of the behavior determination device is installed in the person's house, since the target person is only one,
It is not necessary to provide the PIT 11 with a means for identifying the person carrying the PIT 11. In that case, the determination result determined by the determination unit 24 is output via the output unit 25 or the output unit 25 and the notification unit 2.
7 and will be output to a management center or the like outside the home to care for the target person, such as a public welfare facility, and the behavior of the target person will be managed by the public welfare facility. Will be.

Also, in the above-described first embodiment, it is not described who is the subject to be judged by the action judging device. However, when the subject is an elderly person with dementia, For example, even if the time during which the elderly person enters the toilet 18 is the same as the time of the pattern recorded in the recording means 23, the water usage of the toilet unit differs from the pattern recorded in the recording means 23. If yes, the behavior determination device issues a warning. Therefore, other residents
It is possible to know that the old man is playing abnormally, such as playing in the toilet 18 or washing in the toilet. Also, for example, when an elderly man cooks in a kitchen 14 using a gas range and forgets to extinguish the gas range, the combination of the activity of the elderly person detected by the CCD camera 1a and the like and the operation of the gas range is not possible. If the pattern does not substantially match the pattern recorded in the recording means 23, the action determination device issues a warning, so that the other residents can know that the old man has an abnormality.

Also, for example, when an old man wakes up in the middle of the night and roams around the house, the combination of the action of the old man and the operation of the equipment in the house is recorded in the pattern recorded in the recording means 23. If they do not substantially match, the action determination device issues a warning, so that the other residents can know that the old man has an abnormality. Therefore, the recording means 23
In the pattern recorded in the old man
If the old man actually goes to the toilet 18 or the kitchen 14 at a time when he is to leave and goes to the toilet 18 or the kitchen 14, the pattern is that the refrigerator 22 or the toilet unit is used. Regardless, if the refrigerator 22 or the toilet unit is not used, other residents can know that the elderly are abnormal.

If the subject is a middle-aged person with high blood pressure and the middle-aged person falls down in the kitchen 14, for example,
The position of the elderly is detected by the CCD camera 1a,
A gyro sensor, an acceleration sensor, and an angle sensor incorporated in the PIT 11 detect the activity amount and posture of middle-aged and elderly people, and also detect the operation of equipment in the kitchen 14. The detected behavior of the elderly and
If the combination with the operation of the equipment does not substantially match the pattern recorded in the recording means 23, the action determination device issues a warning. You can know.

In the first embodiment, as an example of the first detecting means of the action judging device of the present invention, the CCD cameras 1a and 1b, the infrared sensor 2, the on-bed sensor 3, the air quality sensor 4, toilet sensor 5, PIT1
1 and the transmission / reception means 12, but the first detection means is not limited to the CCD camera 1 or the infrared sensor 2 described above. The first detecting means only needs to detect the behavior of the target person. In addition, the behavior of the target person also includes the posture, the moving state, and the activity amount of the target person. They are detected by PIT11.

In the first embodiment, the PIT
11 is to transmit an identification number for identifying the person carrying the PIT 11 by radio wave when receiving a predetermined instruction from the transmitting / receiving means 12, but the transmitting means such as the PIT 11 transmits each resident to each resident. An identification number for identification may be transmitted by radio waves periodically or irregularly, regardless of whether or not a predetermined instruction from the transmission / reception unit 12 is received.

In the first embodiment, the transmitting and receiving means 12 identifies the person carrying the PIT 11, but the CCD cameras 1a and 1b, the infrared sensor 2,
All or a part of the occupancy sensor 3, the air quality sensor 4, and the toilet sensor 5 have a function of identifying a person carrying the PIT 11, and use an identification number by radio waves from the PIT 11, The person carrying the PIT 11 may be identified.

In the first embodiment, as an example of the second detecting means of the action judging device of the present invention, the window opening / closing detecting means 6 and 7 and the television power ON / OF are provided.
Although the F detecting means 8 and the refrigerator door opening / closing detecting means 9 are used, the second detecting means is not limited to the window opening / closing detecting means 6 and the television power ON / OFF detecting means 8 described above. The second detection means only needs to detect the operation of a predetermined device.

In the first embodiment described above, the recording unit 23 records the first pattern and the second pattern. However, the recording unit 23 uses the combination of the behavior of the subject and the operation of the device. It is only necessary to record one or more patterns. Therefore, the recording means 23
Is not limited to the one that records the above-mentioned averaged pattern of each month in the year of 1998.
The detection data only for the day may be recorded as a pattern, the one obtained by averaging the detection data for one month, or the one obtained by averaging the detection data for one month for each day of the week may be recorded as a pattern. Is also good. In short, the recording means 23
It is only necessary to record one or more patterns of the combination of the behavior of the subject and the operation of the device. Also,
The determination unit 24 compares one or more patterns recorded by the recording unit 23 with the actual behavior of the target person and the actual operation of the device, and compares the actual behavior of the target person with the actual operation of the device. It is only necessary to judge whether or not the combination with .sub.1 substantially matches any of the patterns recorded by the recording means 23. It should be noted that the above-mentioned substantially matching means that the combination of the behavior of the target person and the operation of the device matches the pattern within a predetermined time range, for example, within 10 minutes, or the case where the target is in the kitchen 14. Both the standing action and the squatting action are identical in that the subject is in the kitchen 14 and therefore within the predetermined range of activity of such subject and / or within the predetermined range of operation of the equipment. Means that the combination of the behavior of the target person and the operation of the device matches the pattern.

In the first embodiment, the determination means 24 determines that the combination of the resident's action and the opening / closing operation of the door of the refrigerator 22 does not substantially match the first pattern or the second pattern. Is determined,
It is assumed that the speaker 13 emits a warning sound.
Alternatively, a warning light that displays a warning by a light signal may be used. In short, the combination of the behavior of the subject and the operation of the device is determined by the determination unit 24.
, It is only necessary to output a warning when it is determined that the pattern does not substantially match any of the patterns recorded in the.

In the first embodiment, the notification means 27 outputs a warning to a speaker which is located in a house different from the house of FIG. 1 and which is connected to the notification means 27 via a telephone line. Although a warning sound is emitted, a warning light that displays a warning by an optical signal may be used as an alternative to the speaker connected to the notification unit 27 via a telephone line. Further, it is assumed that the notification means 27 is not connected to a speaker or a warning light disposed in a house different from the house of FIG. 1 by a telephone line, but is connected by a power line or a dedicated line. Is also good. In any case, the judgment means 2
If it is determined that the combination of the behavior of the subject and the operation of the device does not substantially match any of the patterns recorded in the recording unit 23, the reporting unit 27 is connected. It is only necessary to output a warning to a speaker or a warning light that is present.

In the first embodiment, the determination means 24 determines whether the combination of the behavior of the subject and the operation of the device substantially matches any one of the patterns recorded in the recording means 23. However, the determination unit 24 records the combination of the behavior of the subject, the operation of the device, the physiological state of the subject and / or the mental state of the subject in the recording unit 23. It may be determined whether or not the pattern substantially matches any of the patterns. In this case, the pattern recorded in the recording unit 23 must be a pattern of a combination of the behavior of the subject, the operation of the device, the physiological state of the subject, and / or the mental state of the subject. Also,
Third detection means for detecting the physiological state of the subject and / or the psychological state of the subject must be provided.

Examples of the third detecting means for detecting the physiological state of one of the subjects include a thermometer for measuring the body temperature of the subject, a perspiration meter for measuring the perspiration of the subject,
A heart rate meter that measures the subject's heart rate can be used. As described above, since the PIT 11 has a function of detecting a physiological state such as a heart rate and a body temperature of the wearer, the PIT 11 transmits the physiological information such as the heart rate and the body temperature of the subject by radio waves. Then, the physiological information may be transmitted periodically or irregularly, and the transmission / reception means 12 may receive the radio wave. Then, the determination unit 24 is made to input the physiological information. The physiological information may be directly input to the determination means 24 by the subject himself or his caregiver. Also,
As means for detecting the mental state of the other subject of the third detecting means, all or a part of the above-mentioned thermometer, sweat rate measuring instrument and heart rate meter, and changes in mental state from changes in body temperature, sweat rate and heart rate Can be used.

As described above, the detecting means detects the behavior of the subject, the operation of the device, and the physiological state of the subject and / or the psychological state of the subject. The combination with the subject's physiological state and / or the subject's psychological state is recorded in the recording unit 23 in advance as a pattern. Then, the determination means 24 determines whether or not the combination of the actual behavior of the subject, the operation of the device, the physiological state of the subject and / or the psychological state of the subject, and the pattern substantially match. The determination may be made. As a result, the behavior of the subject, the operation of the device, the physiological state of the subject, and / or the case where the combination of the behavior of the subject and the operation of the device and the pattern are compared are compared.
Or, when the combination with the subject's psychological state and the pattern are compared, it is more accurately determined whether or not the behavior of the subject substantially matches the pattern. .

The determination means 24 determines whether the combination of the behavior of the subject, the operation of the device, and the physiological state of the subject and / or the psychological state of the subject is recorded in any of the patterns recorded in the recording means 23. If it is determined that they do not substantially match each other, the output unit 25 outputs a warning to the speaker 13 or the warning light notification unit, and notifies the warning by voice or a light signal. Similarly, when the determination result determined by the determination unit 24 is negative, the warning transmission unit 26 transmits a warning by radio wave, and the PIT 11
Receives the warning, generates sound, vibration and light based on the warning, and notifies the warning to the carrier. Further, similarly, when the determination result determined by the determination unit 24 is negative, the notification unit 27 outputs a warning to a speaker or a warning lamp connected via a telephone line, a power line, or a dedicated line, and reports the warning. .

Therefore, for example, if the resident
In the case where information regarding the body temperature and the heart rate when the resident is in the bed 17 is recorded in the recording unit 23 in advance as well as the information that the resident is in the bed and the information on the operation of the device. When the determination unit 24 makes the determination, the resident is on the bed 17 and the operation of the device is substantially the same as the recorded pattern, but the resident is on the bed 17. If the value of the body temperature or heart rate when the person is on the floor is higher than the value of the body temperature or heart rate of the pattern, the PIT indicates that the value of the body temperature or heart rate is high.
Since it is detected by the third detecting means such as 11, the determining means 24 determines that the physiological condition of the occupant does not match the pattern, and a warning is issued accordingly. As a result, it is more accurately estimated that an abnormality has occurred in the resident's body, such as a resident having a cold.

Similarly to the first detection means, the third detection means uses information by radio waves for identifying each target person, and has a function of identifying the target person, and a physiological condition and / or Alternatively, a function that can detect a mental state may be set. Further, as described above, the PIT 11 can be used as an example of the third detection unit.

Further, the judgment result determined by the above-mentioned action judgment device is used in order for the subject to manage his / her health or for the caregiver of the subject to manage the health of the subject.
May be used.

The CCD cameras 1a and 1b, the infrared sensor 2, the on-bed sensor 3, the air quality sensor 4, the toilet sensor 5,
And PIT11 are, as described in Embodiment 1,
The behavior of the resident as a target is detected, and each detected data is output to the specifying means 29 in the management means 28. Further, the transmission / reception unit 12 also outputs the information of the person carrying the identified PIT 11 to the specifying unit 29 as described in the first embodiment. The window opening / closing detecting means 6 and 7, the television power ON / OFF detecting means 8, and the refrigerator door opening / closing detecting means 9 are respectively used for opening / closing the windows 19 and 20, turning on / off the power of the television 21, or opening / closing the refrigerator 22 And outputs the detected data to the specifying means 29.

The specifying means 29 specifies the correct occupant behavior based on the input occupant behavior detection data and the detected equipment operation data. For example, CCD camera 1
b, it is detected that the resident has been in the living room 15 for a long time.
When the television power ON / OFF detecting means 8 detects that the power of the television 21 is ON at the time when the TV 21 is detected as being in the 21 is identified as being viewed.

The information providing means 30 selects and provides information based on the correct behavior of the resident specified by the specifying means 29, and causes the speaker 13 to output the information. For example, as described above, the identification means 29 allows the resident to set the television 2 in the living room 15 for a long time.
If it is determined that the user has watched No. 1 and the user is out of exercise, the user is advised to go outside and move his body, along with an exercise menu indicating what kind of exercise should be performed. Note that information to be provided is set in the information providing unit 30, and a part of the set information is information recommending that the body is moved or an exercise menu. For example, as the exercise menu, the specifying means 29
A plurality of menus based on the length of time during which the resident does not exercise correspond to the plurality of menus, and the information providing means 30 determines a plurality of menus based on the length of time during which the resident does not exercise. Select and provide an appropriate menu from the above menus.

The control means 31 controls the opening and closing operation of the window 20 based on the correct behavior of the occupant specified by the specifying means 29. For example, as described above, the specifying unit 2
If it is specified by 9 that the resident has watched the television 21 in the living room 15 for a long time, it is determined that the evocation of the living room 15 is not sufficient, and the window 20 is opened for, for example, 10 minutes.

[0092] The notifying means 32 outputs the correct behavior of the resident specified by the specifying means 29 to a speaker arranged in a house different from the house where the resident lives. Then, the speaker outputs the occupant's action accurately specified by voice. Therefore, a resident in another house can know the behavior of the occupant that is accurately specified.

In the above-described second embodiment, the specifying means 29 allows the resident to use the television in the living room 15 for a long time based on the input detection data of the resident's behavior and the input data of the operation of the device. The operation of the care system of the present invention has been described by taking as an example a case where it is specified that the user watched 21. As described above, the specifying means 29 of the care system of the present invention is a means for specifying the correct behavior of the resident based on the input detection data of the behavior of the resident and the detection data of the operation of the device, For example, if the resident's rhythm of life is disturbed, the resident frequently goes to the toilet, naps on the sofa, the resident is wandering at night, This is a means that can also specify that the user has fallen in a toilet or bathroom.

When the specifying means 29 specifies, for example, that the rhythm of the resident's life is disturbed, the information providing means 30 outputs information prompting regular wake-up from a large number of set information. Select and offer. Also,
When the specifying unit 29 specifies that the resident frequently goes to the toilet, for example, the information providing unit 30 may provide information such as whether or not diabetes is present from among a large number of set information, and requesting a doctor. Select and provide recommended information.

When the specifying means 29 specifies, for example, that the resident is napping on the sofa, the information providing means 30 selects and provides the information "I'll catch a cold" and gives it to the speaker 13. The information is output by voice, and the control means 31 controls the lighting equipment and the air conditioner to darken the room and adjust the temperature of the room to a temperature at which the napping person does not catch a cold. I do. In addition, the notification means 32 outputs information that the resident is napping on the sofa to a speaker arranged in a house different from the house. Then, the loudspeaker outputs the voice of the occupant's behavior accurately identified, so that the resident in another house can know that the occupant is napping on the couch and nap. You can go to a resident to hang a futon.

When the specifying means 29 specifies, for example, that the resident is wandering at night or falls in a toilet or a bathroom, the notifying means 32 sends information to that effect to the home. And output to a speaker located in another house. Then, the speaker will output the voice of the accurately identified occupant's behavior, so that the occupant in another house may be wondering if the occupant is wandering at night or falling down in a toilet or bathroom. Can be known, and a response corresponding to each case can be taken.
