Abstract

PROBLEM TO BE SOLVED: To achieve a higher reliability in detection of abnormality in living and the detection of presence in room for a living abnormality detection system. SOLUTION: A detection signal of a movement detection sensor 10 is received by a control circuit part 2 a receiver 1 includes. When the detection signal of the movement detection sensor 10 fails to be received beyond a specified time length, the control circuit part makes a judgment that abnormality in living (situation in which a resident falls unable to move or the like) and sends an alarm. The movement detection sensor 10 concurrently serving as presence in room detection sensor to detect the presence or non-presence of the resident switches the mode to a 'presence mode' when a presence in room signal is received while a 'non-presence in room mode' is given as the operation mode of the control circuit part. When the movement detection sensor 10 concurrently serving as presence in room detection sensor is arranged at a toilet, the detection of abnormality in living and the detection of presence in room are carried out at the toilet used by most people while living normally. This achieves a higher reliability in the detection of abnormality in living and the detection of presence in room.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifestyle abnormality detection system for detecting the occurrence of a lifestyle abnormality such as a person falling indoors and being unable to move.

[0002]

2. Description of the Related Art A conventional life abnormality detection system includes a movement detection sensor for detecting the movement of a person in a detection area using a heat ray sensor, an infrared sensor, an ultrasonic sensor, or the like. Arranged on the ceiling,
If the detection output from the movement detection sensor is not continuously received by the receiver for a predetermined time or more when a person is present in the house, for example, it is considered that the resident has not entered or left the living room for a long time, It is determined that an abnormality that causes the resident to fall down and become unable to move (hereinafter, such an abnormality is referred to as "life abnormality") is generated and an alarm is issued (Japanese Patent Laid-Open No. 63-44298, etc.). reference).

[0003]

By the way, in the above-mentioned conventional system, when the resident is absent, the operation mode of the receiver is set to "absence mode", and the detection signal from the dynamic detection sensor is transmitted to the receiver. Even if it is not received continuously for a predetermined time (12 hours) or more, it is not determined that a lifestyle abnormality has occurred. However, the presence / absence of the resident is determined based on the locking / unlocking of the occupancy management lock provided at the entrance, and the operation mode of the receiver is switched between the “resident mode” and the “absent mode”. For example, when one person goes out and one person stays at home in a two-person household, the person who goes out locks the room management lock from outside and is determined to be “absent”. Even when a person is at home, the "absent mode" may be set erroneously, and in such a case, even if a living abnormality occurs in the resident, there is a risk of not being able to detect the abnormality and failing to be notified. .

[0004] Therefore, when the receiver receives a detection signal from the dynamic state detection sensor while the "absent mode" is set, the operation mode is switched from the "absent mode" to the "absent mode". Thus, there has been proposed a system for avoiding the above-mentioned unreported life abnormalities. However, in the above-described conventional system, the dynamic detection sensor for detecting a living abnormality is also used as a sensor for detecting the occupant's occupancy, and is arranged in the living room of the house. Even if you are living, you may not be able to enter the detection area of the movement detection sensor, and there is a possibility that a living abnormality is erroneously detected or a room presence cannot be detected.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a life abnormality detection sensor capable of improving the reliability of life abnormality detection and occupancy detection. Things.

When the occupancy detection signal is received from the detection sensor, the operation mode of the receiver is switched from the absence mode to the presence mode. In addition to detecting living abnormalities in the toilets used by the occupants, and by installing occupancy detection sensors in places where occupants frequently pass, delays in occupancy detection can be reduced, and the reliability of living abnormalities detection and occupancy detection can be reduced. Performance can be improved.

[0008] The invention of claim 4 is the invention of claim 1 or 2 or 3.
In the invention, when the receiver receives the occupancy detection signal from the occupancy detection sensor a predetermined number of times within a predetermined time, the receiver switches the operation mode from the absence mode to the presence mode, It is possible to reduce the possibility that the operation mode is erroneously switched from the absence mode to the presence mode due to erroneous detection of the detection sensor, and to improve the reliability of the operation mode switching and, consequently, the life abnormality detection.

BEST MODE FOR CARRYING OUT THE INVENTION

(Embodiment 1) FIG. 1 is a system block diagram of a lifestyle abnormality detection system of this embodiment, and FIG. 2 is a system configuration diagram of the system. This system is installed in, for example, a multi-family housing for the elderly to detect the occurrence of abnormal living such that the resident (elder) falls indoors and cannot move, and notifies the manager of the occurrence of abnormal living. In order to do so, an alarm or the like is issued.

Life abnormality detection board A which is the core of the present system
Is composed of the receiver 1 and the electric lock control unit 20,
Each housing is formed in the distribution board by forming the distribution board with a common size. As shown in FIG. 3, the receiver 1 includes a control circuit section 2 composed of a CPU with a built-in timer, and call push buttons 11 or grip buttons of emergency call switches B _{1 to} B ₃ disposed in a toilet, a bathroom, a bedroom, or the like. Based on a signal corresponding to the locking / unlocking of the occupancy management lock 21 input from the electric lock control unit 20 and the call receiving circuit unit 3 for receiving the emergency call signal transmitted when the user 12 is operated. A presence / absence determination circuit unit 4 for determining the presence / absence of a person in a house, and a display / alarm for issuing an alarm or transferring a signal to the house information panel 30 when the emergency call signal is received or when a living abnormality occurs. / Transfer circuit unit 5.

The electric lock control unit 20 controls the locking and unlocking of the occupancy management lock 21 constituted by an electric lock provided on the entrance door via a metal fitting 22, and is also provided on the entrance door. It controls the unlocking of the door chain 23. Locking and unlocking of the occupancy management lock 21
Operation of an unlocking switch (not shown) disposed indoors,
Alternatively, it is performed in response to the operation of a security code input type locking / unlocking switch (not shown) arranged outdoors. Further, an emergency unlock switch 24 for unlocking the occupancy management lock 21 and the door chain 23 from outside without inputting a password in an emergency is provided. An operation signal of the emergency unlock switch 24 is transmitted to the receiver 1. Is input to the electric lock control unit 20 from the receiver 1 so that the occupancy management lock 21 and the door chain 23 are unlocked. The emergency unlocking switch 24 is installed in an inconspicuous place where a person other than the manager of the apartment house or the like cannot know, so that a third party cannot operate it unnecessarily.

The presence / absence determination circuit 4 of the receiver 1
When a signal indicating that the occupancy management lock 21 is locked from outside is input from the electric lock control unit 20, it is determined that “absence”, and the occupancy management lock 21 remains unlocked or from inside. When a signal indicating that locking has been performed is input from the electric lock control unit 20, it is determined to be “occupied”, and an absence signal or a presence signal is output to the receiver 1. The control circuit unit 2 switches the operation mode from “presence mode” to “absence mode” when an absence signal is input from the presence / absence determination circuit unit 4, and switches to “absence mode” when a presence signal is input. The operation mode is switched from "mode" to "present mode".

Incidentally, a detection signal of the movement detection sensor 10 for detecting the movement of the resident in the detection area is transmitted to the control circuit section 2. This dynamic detection sensor 10
For example, it is configured using a pyroelectric element, and FIG.
As shown in, in the present embodiment is incorporated integrally with the call push button 11 for emergency calls switch B ₁ disposed in the toilet. Emergency call switch B ₁ represents three modules dimensions of the device body to the call push button 11 and dynamic detection sensor 1 of the large square chronic use wiring devices implantable standardized by JIS
0 is provided and the grip button 12 is hung from the above-mentioned body, and is embedded and disposed on the wall surface of the toilet using the mounting frame of the large-sized continuous wiring device. In addition, 19 is a decorative plate which covers the front surface of the mounting frame. Thus emergency call switch B
By incorporating the movement detection sensor 10 integrally with another article disposed and operated on the wall as in ₁ , the movement detection sensor 10 can be disposed on the wall without being noticeable. In this way, by embedding and arranging in a wall using a mounting frame for an embedded wiring device, it can be made even less noticeable, so that residents and visitors are aware of the presence of the dynamic detection sensor 10. There is no worry about it.

On the other hand, the detection area S of the movement detection sensor 10
₁ ... is divided into a plurality of substantially horizontal direction with the optical components of the Fresnel lens or the like as shown in FIGS.
As shown in FIG. 5, when a person moves in the toilet, the person crosses the plurality of detection areas S ₁ ..., So that a detection output can be obtained from the movement detection sensor 10. Next, an operation of detecting a lifestyle abnormality in the present system will be described. First, when the resident is indoors, the control circuit unit 2
The operation mode is set to “mode”. In the “present mode”, the control circuit unit 2 performs a process as shown in the flowchart of FIG. That is, after the control circuit unit 2 resets the built-in timer, the timer count is continued until the detection signal is received from the movement detection sensor 10, and when the detection signal is received from the movement detection sensor 10 during the timer counting, the timer is stopped. Reset. Thus,
When the counting of the predetermined timer time (for example, 12 hours) is completed without receiving the detection signal from the movement detection sensor 10, the control circuit unit 2 outputs an advance call alarm to the display / alarm / transfer circuit unit 5. You. The display / alarm / transfer circuit unit 5 that has received the advance call alarm only prepares to issue an alarm, but does not issue an actual alarm. After outputting this notice call alarm, the control circuit unit 2 newly starts a timer count of the notice time, and if a restoration signal by operating the restoration button 14 is received during the timer count, the display / display is started.
The warning / transfer circuit unit 5 outputs a notice of cancellation of the advance call alarm and starts counting the original timer time. Conversely, when the timer count of the notice time ends without receiving the restoration signal, the display / alarm /
An alarm for occurrence of a living abnormality is transmitted to the house information panel 30 via the transfer circuit unit 5.

On the other hand, when the resident is not indoors, the control circuit section 2 sets the "absence mode", and the detection signal from the movement detecting sensor 10 is continuously transmitted to the control circuit section 2 for a predetermined time (12 The basic operation in the “absence mode” is that it is not determined that a lifestyle abnormality has occurred even if the reception is not received for a time or longer. However, as described above, if the presence / absence of the resident is determined based on the locking / unlocking of the occupancy management lock 21 and the “resident mode” and the “absence mode” are switched, for example, 2 If one person goes out and one person is at home in a residential household,
When a person who goes out locks the occupancy management lock 21 from outside, it is determined to be “absent”, and the “absence mode” may be erroneously set even though one person is actually at home. .

Therefore, when the control circuit unit 2 receives a detection signal from the motion detection sensor 10 while the operation mode is set to the "absence mode", the operation mode is switched from the "absence mode" to the "presence mode". If the detection signal from the control unit 10 is not received for a predetermined time or more, it is determined that a lifestyle abnormality has occurred, and processing such as issuing an alarm is performed.
That is, in the present embodiment, by arranging the movement detection sensor 10 on a wall surface of a toilet that is expected to enter and exit several times a day in normal life due to human physiological phenomena,
The reliability of life abnormality detection can be improved as compared with a configuration that detects a living abnormality in a living room as in a conventional system. Further, since the toilet is a place where small animals such as pets do not easily enter, erroneous detection by small animals can be reduced. Furthermore, since there are few cases where a curtain or the like is installed in a toilet, it is possible to reduce erroneous detection of curtain fluctuation caused by outside air. In addition, since the movement detection sensor 10 for detecting a living abnormality is also used as the occupancy detection sensor for detecting the occupancy of the resident, the reliability of the occupancy detection can be improved.

An occupancy confirmation switch 13 is provided indoors. When this switch 13 is operated, an occupancy confirmation signal is transmitted to the control circuit section 2 and the control circuit section receives the occupancy confirmation signal. 2 is a predetermined time after reception (for example, 3 minutes)
When the occupancy management lock 21 is not locked from the outside, the operation mode is maintained in the “presence mode”, and when the occupancy management lock 21 is not locked from the outside within a predetermined time, the operation mode is switched to the “absence mode”. Thereby, the presence / absence of the resident can be grasped more reliably.

In this embodiment, unlike the conventional ceiling-mounted type motion detection sensor, the motion detection sensor 10 is embedded in the wall surface and the detection area S ₁ of the motion detection sensor 10 is normal. Place on a wall surface that detects human movement and does not detect the movement of a fallen person or the movement of non-human objects (small animals such as dogs and cats as pets) when abnormal living conditions occur. It is arranged. Specifically, as shown in FIG. 8, the height from the floor surface to the movement detection sensor 10 is 50 cm to 60 cm, and the horizontal distance from the tip of the toilet 42 is 20 cm to 40 cm.
[Cm]. However, the height from the floor is preferably in the range of about 50 cm to 100 cm. The detection area S of the dynamic detection sensor 10 is determined by, for example, partially shielding the light receiving surface of the pyroelectric element.
₁ are set in a substantially fan-shaped horizontal plate shape by narrowing the width in the vertical direction and widening the width in the horizontal direction. By adopting such a configuration, for example, as shown in FIG. 9, even when a small animal (such as a dog) X is in the toilet, the small animal X or falls down in the detection area S ₁ of the dynamic detection sensor 10. It is possible to reduce the possibility that a part of a human body enters, and reduce erroneous detection such as dynamics of a small animal or tremor of a fallen person.

The housing information panel 30 is connected to a detector 32 such as a smoke detector, a gas detector 33 for detecting gas leaks, and a door phone handset 31 installed at the entrance, so that a fire or gas leak may occur. By detecting the occurrence of an abnormality such as the above, it is possible to notify the management center 36 of the occurrence of the abnormality through the telephone line 35, and to respond to the visitor by the intercom slave unit 31.

(Embodiment 2) FIG. 10 shows a system block diagram in this embodiment. Since the basic configuration is the same as that of Embodiment 1, common parts are denoted by the same reference numerals. Description is omitted. In the present embodiment, a buzzer 15 which is installed in a caretaker's office or the like and which is sounded by a signal from the display / alarm / transfer circuit 5 of the receiver 1 when a living abnormality occurs, is installed on the outdoor side of the entrance, etc. An outdoor display 16 for receiving a signal from the display / alarm / transfer circuit unit 5 of the receiver 1 and displaying (for example, turning on an emergency light) when an abnormality occurs, a wireless transmitter 18 carried by each resident.
And a home monitor panel 38 instead of the house information panel 30. This in-home monitoring panel 38
When a transmission signal from the receiver 1 is received at the time of occurrence of a living abnormality or an emergency call, the automatic notification device 39 transmits an alarm or the like to a center device 40 such as a security company via a public telephone line 35.

In this embodiment, as shown in FIG. 11, an electric light switch 41 for turning on / off the lighting equipment and the movement detection sensor 10 are integrally formed, and a mounting frame for an embedded wiring equipment is provided. As shown in FIG. 12, it is embedded in the wall of a living room in a house. Here, the movement detection sensor 10 detects the movement of a person when the detection area S ₁ is normal, and detects a tremor of a fallen person or a non-human thing (a dog or a cat kept as a pet) when a living abnormality occurs. The small animal (e.g., small animal) is located at a position on the wall surface such that the movement of the animal is not detected. Specifically, as shown in FIG. 12, the height is such that a person sitting directly on the floor does not enter the detection area S ₁ .
What is necessary is just to arrange in the position which becomes 0 [cm]-100 [cm]. Also, as in the first embodiment, the width of the detection area S ₁ of the movement detection sensor 10 in the vertical direction is reduced. Thus, unlike the case of disposing in a toilet as in the first embodiment, in the case of disposing in a living room, the movement of a curtain disposed in a window of the living room is prevented from entering the detection area S ₁ . It is also necessary, by adopting the above configuration,
For example, even if a small animal (such as a dog) moves around in the living room as shown in FIG.
Is less likely to have a small animal or a part of the body of a fallen person or a curtain swaying by the wind in the detection area S ₁ . Can be reduced. The movement detection sensor 10 may be configured integrally with the recovery button 14 as shown in FIG.

As in the present embodiment, if the movement detection sensor 10 is integrated with an article (light switch 41, recovery button 14, etc.) installed on a wall surface and operated by a person, the article can be operated to such an extent that the article can be operated. The movement detection sensor 10 can be provided at an appropriate height at which a normal person can be detected. (Embodiment 3) As described above, in Embodiment 1, the movement detection sensor 10 for detecting a living abnormality, which is provided on the wall surface of the toilet, is also used as a presence detection sensor for detecting the presence / absence of a resident. When the receiver 1 receives a detection signal from the dynamic detection sensor 10 in the absence mode, the operation mode is switched from the absence mode to the presence mode.

On the other hand, a movement detection sensor 1 for detecting a living abnormality
0 needs to be provided in a place where false detection is not performed as much as possible. For this reason, in the first embodiment, the erroneous detection as described above is provided by disposing the dynamic detection sensor 10 on the wall surface of the toilet, which is assumed to enter and exit several times a day in a normal life due to human physiological phenomena. The likelihood is low.

In this embodiment, as another form, a occupancy detection sensor for detecting the presence / absence of a resident is provided separately from the dynamic detection sensor 10, and occupants such as corridors and living rooms frequently pass and stay. One or a plurality of occupancy detection sensors are arranged in a place where the occupants are likely to be at home, so that there is no delay in detecting a resident resident. Note that this point has a feature of the present embodiment, and other basic configurations are common to the first or second embodiment. Therefore, illustration and description of common parts are omitted, and Only the characteristic portions will be described.

FIG. 15 is a diagram showing a partially omitted system configuration which is a feature of the present embodiment. A plurality of occupancy detection sensors 25 are connected in series to the presence / absence determination circuit unit 4 of the receiver 1. is there. These occupancy detection sensors 25 have a pyroelectric element and detect the motion of a person in the detection area, and are substantially the same in structure as the motion detection sensor 10 for detecting a living abnormality. As shown in FIG. 16, a plurality of places in a dwelling unit (for example, a corridor, a kitchen and a living room, a Japanese-style room,
It is installed on the wall of the bedroom and toilet.

When a detection signal from any of the occupancy detection sensors 25 is received by the presence / absence determination circuit unit 4 of the receiver 1, the presence / absence determination circuit unit 4 sends the detection signal to the control circuit unit 2. On the other hand, a signal indicating the occupant's occupancy is output, and upon receiving this signal, the control circuit unit 2 performs a process of switching to the “resident mode” when the operation mode is the “absent mode” (the flowchart of FIG. 17). reference). As described above, as soon as the occupant's movement is detected by any of the plurality of occupancy detection sensors 25, the mode is switched from the "absence mode" to the "presence mode", thereby reducing the occurrence of the detection delay as described above. Can be.

It is possible to determine that the occupant is occupied only when a plurality of detection signals are transmitted from the occupancy detection sensors 25 a predetermined number of times or more. FIG. 18 is a flowchart showing specific processing, and the control circuit unit 2
Counts the number of times that the signal indicating the presence of a room is input from the presence / absence determination circuit section 4, and switches the operation mode from the "absence mode" to the "presence mode" when the count exceeds a predetermined number of times. Note that the set number of times can be set to an arbitrary value by the count number setting unit 6 provided in the receiver 1.

Alternatively, as shown in FIG. 19, a plurality of occupancy detection sensors 25 are connected in parallel to the occupancy / absence determination circuit 4, and a detection signal from any one of the occupancy detection sensors 25 is received. After that, another occupancy detection sensor 2 within a predetermined time.
Only when the detection signal is received from 5 as well, it may be determined that the resident is present, and a process of switching the operation mode may be performed. For example, as shown in the flowchart of FIG. 20, when the presence / absence determination circuit unit 4 receives a detection signal from any of the occupancy detection sensors 25, the control circuit unit 2 starts counting the timer time and ends counting. If no new detection signal is received by then, the first detection signal is determined to be erroneous detection, and the operation mode is kept in the “absent mode”. On the other hand, if a new detection signal is received and before the count of the timer ends, the control circuit unit 2 determines that the occupant is present and sets the operation mode to “absent mode”.
To "mode". By performing such processing, the frequency of occurrence of the above-described inconvenience due to erroneous detection of the occupancy detection sensor 25 can be reduced. The timer time can be set to an arbitrary value by the timer time setting unit 7 provided in the receiver 1. In FIG. 16, the occupancy detection sensor 25 and the movement detection sensor 10 installed in the toilet may be configured integrally or may be configured separately.

[0033]

According to the first aspect of the present invention, there is provided a movement detection sensor for detecting the movement of a person in a detection area, and two operation modes of a presence mode and an absence mode. If the detection output is not received continuously for a predetermined time or more, the living abnormality is determined to have occurred to the resident and a predetermined processing is performed to notify the occurrence of the living abnormality. In the detection system, an occupancy detection sensor for detecting an occupancy of a person in the house is provided, and the occupancy detection sensor and the movement detection sensor are disposed in a toilet of the house, and the operation mode of the receiver is an absence mode. When the occupancy detection signal is received from the occupancy detection sensor at the time of, the operation mode of the receiver is switched from the absence mode to the presence mode, so if the person is living normally Resistance by performing the occupancy sensing and life abnormality detection in toilet is utilized, there is an effect that it is possible to improve the reliability of the occupancy sensing and life abnormality detection.

According to a second aspect of the present invention, the occupancy detection sensor detects the occupancy of a person in a detection area in the same manner as the occupancy detection sensor. There is an effect that the sensor can be shared. The invention according to claim 3 has a movement detection sensor for detecting the movement of a person in the detection area, and two operation modes of a presence mode and an absence mode, and in the presence mode, a detection output from the movement detection sensor is predetermined. In a lifestyle abnormality detection system comprising: a receiver that determines that a lifestyle abnormality has occurred to a resident at the time of not being continuously received for more than a time and performs a predetermined process to notify the occurrence of the lifestyle abnormality, A motion detection sensor is provided in the restroom of the house, and a room detection sensor for detecting the presence of a person is provided at least in a place other than the toilet, and the presence mode is set when the operation mode of the receiver is the absence mode. When the occupancy detection signal is received from the detection sensor, the operation mode of the receiver is switched from the absence mode to the presence mode, so most people who are living normally use it. Improve the reliability of life abnormality detection and occupancy detection by detecting occupancy abnormalities in toilets and installing occupancy detection sensors in places where occupants frequently pass, thereby reducing delays in occupancy detection. There is an effect that can be made.

According to a fourth aspect of the present invention, when the receiver receives the occupancy detection signal from the occupancy detection sensor a predetermined number of times within a predetermined time, the receiver switches the operation mode from the absence mode to the presence mode. In addition, it is possible to reduce the possibility that the operation mode is erroneously switched from the absence mode to the presence mode due to the erroneous detection of the occupancy detection sensor, and it is possible to improve the reliability of the switching of the operation mode and the life abnormality detection.

According to the fifth aspect of the present invention, since the plurality of occupancy detection sensors are arranged in a house, there is an effect that the operation mode can be quickly switched from the absence mode to the presence mode. According to a sixth aspect of the present invention, when the receiver receives an occupancy detection signal from at least one of the plurality of occupancy detection sensors, the receiver switches the operation mode from the absence mode to the presence mode. There is an effect that the operation mode can be switched to the on-mode, and the life abnormality detection can be quickly performed.

According to a seventh aspect of the present invention, the receiver detects an occupancy from another occupancy detection sensor within a predetermined time after receiving the occupancy detection signal from at least one of the plurality of occupancy detection sensors. Since the operation mode is switched from the absence mode to the presence mode when a signal is received, it is less likely that the operation mode is erroneously switched from the absence mode to the presence mode due to erroneous detection of the presence sensor. As a result, there is an effect that the reliability of life abnormality detection can be improved.

According to the present invention, the occupancy detection sensor is disposed on an indoor wall so that the detection area of the occupancy detection sensor is at least a range in which the movement of an object other than a person is not detected in a normal state. Therefore, it is possible to reduce malfunctions caused by detecting factors other than the movement of a person living normally, such as the movement of small animals such as dogs and cats kept as pets. is there.

According to the ninth aspect of the present invention, since the width of the detection area in the vertical direction in the occupancy detection sensor is reduced, factors other than the movement of a normally living person, such as a pet, are kept. There is an effect that malfunctions caused by detecting movement of small animals such as dogs and cats can be further reduced.
