Description

  The present invention relates to an emergency call system that detects a resident's abnormality in a house where an elderly person or the like lives and issues a report.

  Conventionally, with the progress of the nuclear family and the like, the number of houses where only elderly people live is increasing. In addition, collective housings are known in which housings in which such elderly people live are collected and managed by a manager room or the like.

In such a housing complex, the motion of a resident in the room is detected by an infrared sensor or the like, and if the time that cannot be detected by the infrared sensor exceeds a predetermined time, it is determined that the resident has an abnormality and an alarm is given. Is known (for example, Patent Document 1).
JP-A 61-279221

  Even if the infrared sensor cannot detect the movement of the resident, the technique described in Patent Document 1 causes an abnormality in the resident when the bedtime is in light of the pattern of the time schedule of daily life. Judge that it is not.

  However, in the technique described in Patent Document 1, when it is bedtime as a pattern of the time schedule of daily life, even when an abnormality related to the life of the resident occurs, it is detected and alarmed. There was a problem that could not be issued.

By the way, when a resident enters a life-threatening state such as cardiac arrest or stroke, the residence is fixed during sleep, for example, by attaching an electroencephalogram / body motion sensor / transmitter unit to the resident's wrist. A technique is known that can detect a resident's state and issue an alarm even during a certain time period (for example, Patent Document 2).
JP 2002-42277 A

  However, in the technique described in Patent Document 2, it is necessary to attach a unit to the occupant's wrist.

  The present invention has been made to solve such a problem, and detects even if an abnormality related to the life of a resident occurs during sleep without placing a burden on the resident. The purpose is to be able to report.

  In order to solve the above-described problems, in the present invention, the bedding is divided into a plurality of areas, and each area is provided with a pressure-sensitive sensor that detects the weight and a temperature sensor that detects the temperature. When a weight higher than the first value is detected, the temperature sensor detects a temperature higher than the second value in the area where the pressure sensor detects the weight higher than the first value. Whether or not the temperature sensor detects that the temperature is not equal to or higher than the second value is notified.

  According to another aspect of the present invention, the bedding is divided into a plurality of regions, and each region is provided with a pressure-sensitive sensor that detects the weight and a temperature sensor that detects the temperature. Whether the temperature sensor detects a temperature higher than the second value in the area where the pressure sensor detects the weight higher than the first value when a weight higher than the first value is detected Determine whether or not. Then, if it is determined that the temperature sensor has detected a temperature equal to or higher than the second value, it is determined that the resident is sleeping, and then the pressure sensor detects a weight higher than the first value. When it is determined that the temperature sensor detects a temperature higher than the second value in the area where the temperature sensor is not detecting a temperature higher than the second value I am doing so.

  According to the present invention configured as described above, it is determined that the resident is sleeping by detecting the weight on the bedding, and the resident is detected by detecting the temperature of the area where the weight is detected. It is judged whether or not the body temperature of the resident is in an abnormal state, so that when there is an abnormality related to the life of the resident such as a decrease in the body temperature of the resident during sleep, without burdening the resident , It can be detected and reported.

  Further, according to another aspect of the present invention, when the pressure sensor detects a weight greater than or equal to the first value, the temperature sensor operates in a region where a weight greater than or equal to the first value is detected. Since a resident's sleep is determined when a temperature equal to or higher than the second value is detected, it is possible to prevent a false alarm that occurs when an object other than the resident gets on the bedding.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration example of an emergency call system according to the present embodiment. As shown in FIG. 1, the emergency notification system according to the present embodiment includes a living room device 1 provided in each dwelling unit in the apartment house, and a management room device 10 provided in a manager's room or the like. The living room apparatus 1 includes a plurality of pressure sensors 2, a plurality of temperature sensors 3, a resident determination unit 4, a body temperature determination unit 5, a room control unit 6, and a room interface 7. The management room device 10 includes a management room control unit 11, a management room interface 12, and a notification unit 13.

  As shown in FIG. 2, the pressure-sensitive sensor 2 is provided in each of a plurality of regions obtained by dividing the plane of the sheet A laid at a predetermined position inside or below the bed mattress or mattress, Each detects the weight. As shown in FIG. 2, the temperature sensor 3 is provided so as to correspond to the pressure-sensitive sensor 2 in a plurality of regions obtained by dividing the plane of the sheet A, and detects the temperature.

  The resident determination unit 4 is connected to all the pressure sensitive sensors 2, and determines whether or not the pressure sensitive sensor 2 detects a weight equal to or greater than the first value. And when the pressure sensor 2 detects the weight more than a 1st value, the resident determination part 4 judges that a resident exists on the mattress or mattress of a bed. Here, the resident determination unit 4 determines that there is a resident on the mattress or mattress of the bed even when some of the pressure-sensitive sensors 2 detect a weight equal to or greater than the first value. The first value is preferably set as appropriate depending on the occupant's weight and the like, and further varies depending on the number of pressure-sensitive sensors 2.

  In addition, by increasing the number of pressure sensors 2, the occupant determination unit 4 allows the pressure sensor 2 on a part of the bed to detect a weight that is equal to or greater than the first value on the mattress of the bed or a mattress. It may be determined that there is no resident above. That is, it is possible to exclude a case where an object other than a resident has fallen on a bed mattress or a mattress.

  The body temperature determination unit 5 is connected to all the temperature sensors 3, and the temperature sensor corresponding to the pressure-sensitive sensor 2 that is determined by the occupant determination unit 4 to detect a weight greater than or equal to the first value. It is determined whether 3 is detecting a temperature equal to or higher than the second value. Here, the second value is preferably set as appropriate depending on the distance between the temperature sensor 3 and the occupant existing on the mattress or mattress of the bed and the inclusions (sheets, etc.). The value varies depending on age and gender.

  The living room control unit 6 controls each component of the living room device 1, and the temperature sensor 3 corresponding to the pressure sensor 2 that is determined by the resident determination unit 4 to detect a weight equal to or greater than the first value. When the body temperature determination unit 5 determines that a temperature equal to or higher than the second value is not detected, a notification signal is generated and output. Here, the notification signal indicates that the resident's body temperature on the bed mattress or mattress has become lower than a predetermined value (often different from the second value). . Further, the notification signal includes an identification signal for specifying the room (or resident) that made the notification.

  The room interface 7 is for connecting the room device 1 and the management room device 10, and outputs a report signal input from the room control unit 6 to the management room device 10.

  The management room control unit 11 controls each component of the management room device 10. The management room interface 12 is for connecting the management room device 10 and the living room device 1, and inputs a notification signal output from the living room device 1. The reporting unit 13 includes a speaker, a display lamp, a display, and the like, and reports that a room (or a resident) specified by the identification signal included in the report signal and an abnormality have occurred.

  Next, the operation of the emergency call system and the bedtime notification method according to the present embodiment will be described. FIG. 3 is a flowchart showing the operation of the emergency call system and the bedtime notification method according to the present embodiment. First, in the living room apparatus 1, the resident determination unit 4 checks whether or not the pressure-sensitive sensor 2 has detected a weight greater than or equal to the first value (step S1). If the occupant determination unit 4 determines that the pressure sensor 2 has not detected a weight greater than or equal to the first value (NO in step S1), the process returns to step S1.

  On the other hand, if the resident determination unit 4 determines that the pressure sensor 2 has detected a weight greater than or equal to the first value (YES in step S1), the sense that the weight greater than or equal to the first value has been detected. Whether the temperature sensor 3 corresponding to the pressure sensor 2 detects a temperature equal to or higher than the second value is checked by the body temperature determination unit 5 (step S2). If the body temperature determination unit 5 determines that the temperature sensor 3 has detected a temperature equal to or higher than the second value (YES in step S2), it is determined that no abnormality has occurred in the resident, and in step S1 Return to processing.

  On the other hand, when the body temperature determination unit 5 determines that the temperature sensor 3 has not detected a temperature equal to or higher than the second value (NO in step S2), the room control unit 6 generates an abnormality in the resident. A notification signal is generated and output. In the management room device 10, the management room control unit 11 checks whether or not a notification signal is input (step S4). If management room control unit 11 determines that a notification signal has not been input (NO in step S4), the process returns to step S4. On the other hand, when the management room control unit 11 determines that the notification signal has been input (YES in step S4), the management room control unit 11 operates the notification unit 13 and an abnormality has occurred in the resident. (Step S5).

  As described above in detail, according to the present embodiment, the bedding is divided into a plurality of regions, and the pressure sensor 2 that detects the weight and the temperature sensor 3 that detects the temperature are provided in each region. When the pressure sensor 2 detects a weight greater than or equal to the first value, the temperature sensor 3 is greater than or equal to the second value in a region where the pressure sensor 2 detects a weight greater than or equal to the first value. It is determined whether or not the temperature is detected, and when it is determined that the temperature sensor 3 has not detected a temperature equal to or higher than the second value, a notification is made.

  Thereby, it is determined that the resident is sleeping by detecting the weight on the bedding, and whether the occupant's body temperature is abnormal by detecting the temperature of the area where the weight is detected. Because it is judged, when a resident's life-related abnormality such as a decrease in the resident's body temperature occurs during sleep, it should be detected and reported without burdening the resident. Can do.

  In the above-described embodiment, it is determined that the resident is on the bedding when the pressure sensor 2 detects a weight equal to or greater than the first value, but the present invention is not limited to this. For example, when the pressure sensor 2 first detects the first weight, it may be determined that the resident is on the bedding when the temperature sensor detects a temperature equal to or higher than the second value. .

  Specifically, as shown in FIG. 4, the sleep determination unit 8 is provided in the living room device 1, and the resident determination unit 4 determines that the pressure sensor 2 detects a weight equal to or greater than the first value. In this case, the body temperature determination unit 5 determines whether or not the temperature sensor 3 detects a temperature equal to or higher than the second value in a region where the pressure sensor 2 detects a weight equal to or higher than the first value. Then, when the body temperature determination unit 5 determines that the temperature sensor 3 detects a temperature equal to or higher than the second value, the bed determination unit 8 determines that the resident is sleeping. When the sleep determination unit 8 determines that the resident is sleeping, the living room control unit 6 uses the temperature sensor in a region where the pressure sensor 2 detects a weight greater than or equal to the first value. The body temperature determination unit 5 determines again whether 3 is detecting a temperature equal to or higher than the second value. When the body temperature determination unit 5 determines that the temperature sensor 3 has not detected a temperature equal to or higher than the second value by this determination, the room control unit 6 outputs a notification signal.

  As a result, when the pressure sensor 2 detects a weight greater than or equal to the first value, the temperature sensor 3 detects a temperature greater than or equal to the second value in the region where the weight greater than or equal to the first value is detected. Since the sleep of the resident is determined when it is detected, it is possible to prevent a false alarm that occurs when an object other than the resident gets on the bedding.

  Further, in the above-described embodiment, the body temperature determination unit 5 is provided in the seat A, but is not limited thereto. For example, a thermography camera capable of photographing the bedding may be used to detect the temperature of the area where the pressure sensor 2 is provided.

  Moreover, in embodiment mentioned above, determination whether the pressure sensor 2 is detecting the weight more than 1st value, whether the temperature sensor 3 is detecting temperature more than a 2nd value, etc. However, the present invention is not limited to this, and may be performed by the management room device 10. Similarly, in the above-described embodiment, the reporting unit 13 is provided in the management room device 10, but is not limited thereto, and may be provided in the living room device 1.

  In addition, the said embodiment is only what showed the example in implementation in implementing this invention, and, as a result, the technical scope of this invention should not be interpreted limitedly. In other words, the present invention can be implemented in various forms without departing from the spirit or main features thereof.
