  By the way, in the conventional house monitoring system including patent document 1, since it is assumed that a resident | carrying person carries a wireless cordless handset, even if a resident | carrying person does not carry a wireless cordless handset, the residence in a living room There was a problem that it was determined that there was an abnormality in the person.

  The present invention is made in order to solve such a problem, and it is determined whether or not a resident is carrying a wireless handset, and then reports an abnormality in the living room to the manager. With the goal.

In order to solve the above-described problems, in the present invention, a human sensor that detects the movement of a person in a living room and a transmission signal from a wireless slave device carried by a resident, When the receiver to be acquired is installed in the room and the reception level value is less than the predetermined value, it is determined that the resident is absent and the reception level value exceeds the predetermined value. It is determined that the resident is in the room. On the other hand, the reception level value obtained by the receiver is measured every predetermined time, and when the human sensor detects the movement of the person, the latest reception level value and at least one of the reception level values before and after When it is determined that there is no change, it is determined that the resident is not carrying the wireless slave unit, and when it is determined that there is a change, the resident is carrying the wireless slave unit. Judge . Only when it is determined that the occupant is in the room and the resident is determined to carry the wireless slave device, the administrator is notified of the abnormality.

  Also, according to another aspect of the present invention, when it is determined that the person is absent, when the human sensor detects the movement of the person, the manager is notified that an abnormality has occurred in the room. .

  According to the present invention configured as described above, in the case where the value of the reception level from the wireless slave unit does not change before or after the detection even though the human sensor detects the movement of the person, Since it is determined that the wireless handset does not exist in the same place, it can be determined whether the resident is carrying the wireless handset. In addition, when it is determined that the value of the reception level from the wireless slave is greater than or equal to a predetermined value, it is determined that the resident is in the room and the resident is determined to carry the wireless slave. When the human sensor does not detect the movement of the person for a predetermined time or more, the administrator is notified that there is an abnormality in the resident, so it is determined whether the resident is carrying a wireless slave unit. Above, you can report the abnormalities in the room to the manager.

  According to another aspect of the present invention, when it is determined that the value of the reception level from the wireless slave unit is less than a predetermined value, it is determined that the resident carrying the wireless slave unit is absent, In this state, when the human sensor detects the movement of the person, the manager is notified that there is an abnormality, so the abnormality in the room can be notified to the administrator.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating an arrangement example of the dwelling unit monitoring system according to the present embodiment. FIG. 2 is a block diagram illustrating a configuration example of the dwelling unit monitoring system according to the present embodiment. As shown in FIGS. 1 and 2, the dwelling unit monitoring system according to the present embodiment includes a wireless slave unit 1, a receiver 10, a human sensor 20, a dwelling unit controller 30, and a management room base unit 40. . Here, the wireless slave device 1 is carried by a resident and is hung on the resident's neck or the like by a string attached to the housing of the wireless slave device 1. Note that an operation button that is operated when the resident calls an administrator or the like may be provided on the wireless slave device 1. Of course, a plurality of rooms may exist.

  The wireless slave unit 1 includes a slave unit control unit 2, a slave unit storage unit 3, and an operation unit 4. The slave unit control unit 2 controls each component of the wireless slave unit 1. The handset storage unit 3 stores handset identification information uniquely assigned to the wireless handset 1. The subunit | mobile_unit control part 2 acquires subunit | mobile_unit identification information from the subunit | mobile_unit control part 3, and produces | generates the transmission signal containing this subunit | mobile_unit identification information. Here, the transmission signal is for confirming the location of the wireless slave unit 1. The subunit | mobile_unit transmission part 4 transmits the transmission signal produced | generated in the subunit | mobile_unit control part 2 for every predetermined time (for example, 1 second etc.).

  The receiver 10 is installed in a living room, and is arranged so that a resident can receive a transmission signal from the wireless handset 1 wherever the resident is. If one receiver 10 cannot cover the entire area of the room, two or more receivers 10 may be used. The receiver 10 includes a receiver control unit 11, a receiving unit 12, a measuring unit 13, and a receiver interface 14. The receiver control unit 11 controls each component of the receiver 10. The receiving unit 12 receives a transmission signal transmitted from the wireless slave device 1 via an antenna (not shown). The measuring unit 13 measures the value of the reception level of the transmission signal received by the receiving unit 12. Normally, the closer the wireless slave device 1 is to the antenna, the greater the value of the reception level of the transmission signal measured by the measurement unit 13. Here, the receiver control unit 11 operates the measuring unit 13 every time the receiving unit 12 receives a transmission signal, and performs measurement. For this reason, when the wireless slave unit 1 is present in the living room, measurement is performed every predetermined time described above.

  The receiver interface 14 is for connecting the receiver 10 and the dwelling unit controller 30, and is connected to the dwelling unit controller interface 32 by wire. The receiver interface 14 outputs a value of the reception level measured by the measurement unit 13. The receiver control unit 11 operates the receiver interface 14 every time the measurement unit 13 measures the value of the reception level, and outputs the value of the reception level.

  The human sensor 20 is installed in the living room, detects a human movement, and outputs a detection signal. Here, the human sensor 20 is installed in a place where residents often pass. The human sensor 20 and the dwelling unit controller interface 32 are connected by wire.

  The dwelling unit controller 30 is for controlling each device in the living room, and is installed in the vicinity of the living room such as the living room or outside the living room. The dwelling unit controller 30 includes a dwelling unit control unit 31, a dwelling unit control unit 32, a reception level storage unit 33, a presence / absence determination unit 34, a carry determination unit 35, and a timing unit 36. The dwell unit controller control unit 31 controls each component of the dwell unit controller 30. The dwell unit controller interface 32 is for connecting the dwell unit controller 30 and the receiver 10, and is connected to the receiver interface 14 by wire. Then, the dwell unit controller interface 32 inputs the value of the reception level from the receiver 10. Further, as described above, since the dwelling unit controller interface 32 and the human sensor 20 are connected by wire, the dwelling unit controller interface 32 inputs a detection signal from the human sensor 20. The dwell unit control unit interface 32 is for connecting the dwell unit control unit 30 and the management room main unit 40, and is connected to the main unit interface 42 by wire. An abnormality notification signal described later is output from the dwelling unit controller interface 32 to the management room master unit 40.

  The reception level storage unit 33 stores the value of the reception level input by the dwelling unit controller interface 32 in time series. Here, the reception level storage unit 33 may store the reception level value for a certain period. For example, if the reception level value for 24 hours can be stored, the previous reception level value is stored. May be automatically deleted.

  The presence / absence determination unit 34 checks whether the value of the reception level input by the dwelling unit controller interface 32 is less than a predetermined value or greater than a predetermined value, and determines that the value of the reception level is less than a predetermined value. If it is determined that the resident is absent, and it is determined that the value of the reception level is equal to or higher than a predetermined value, it is determined that the resident is made of material. Here, the predetermined value is a value at which the receiver 10 receives a transmission signal when the resident leaves the room. Therefore, when the interior of the dwelling unit is shielded so that the receiver 10 cannot receive any transmission signal from the wireless slave unit 1 outside the room, the predetermined value is close to zero. In the present embodiment, the case where the value is less than the predetermined value and the case where the value is greater than or equal to the predetermined value are separated, but the present invention is not limited to this. For example, it may be possible to divide both when the value is less than a predetermined value and when the value is larger than the predetermined value.

  The carrying determination unit 35 is for determining whether or not a resident is carrying the wireless slave device 1. Specifically, when the dwelling unit controller 32 receives a detection signal, the carrying determination unit 35 receives the latest reception level value stored in the reception level storage unit 33 and the previous reception level value. And compare the two. The carry determination unit 35 may compare the latest reception level value stored in the reception level storage unit 33 with the reception level value input from the receiver 10 immediately thereafter. Further, the carrying determination unit 35 may compare the latest reception level value stored in the reception level storage unit 33 with the previous and next reception level values. In addition, when the transmission interval of the transmission signal generated by the wireless slave unit 1 is too short (1 second in the present embodiment) and the reception level does not change (the occupant's moving speed is slow, 1 second When there is no change), a time interval between the latest reception level value and the compared reception level value may be set (for example, every 5 seconds).

  When the carrying determination unit 35 determines that there is no change between the two (three when compared with the previous and subsequent reception levels) (the change of both falls within a certain range), the resident It is determined that the aircraft 1 is not carried. On the other hand, the carrying determination unit 35 determines that the resident is carrying the wireless slave device 1 when it is determined that there is a change between them (they do not fall within a range where both the changes are present). The case where the human sensor 20 detects the movement of the resident indicates that the resident has moved from a place where the movement is not detected by the human sensor 20 to a place where the movement is detected by the human sensor 20. . Therefore, the fact that the value of the reception level has not changed even though the resident has moved can be determined that the resident is not carrying the wireless handset 1 (for example, the state shown in FIG. 3). ). Further, when the resident moves, the value of the reception level changes, so that it can be determined that the resident is carrying the wireless slave device 1 (for example, the state shown in FIG. 1).

  The time measuring unit 36 is for measuring time, and starts measurement in response to an instruction from the dwelling unit controller control unit 31, ends measurement and starts measurement again in response to an instruction from the dwelling unit controller control unit 31 ( Reset.

  When the presence / absence determination unit 34 determines that the user is in the room, the following operation is performed. The dwelling unit control unit 31 operates the time measuring unit 36. And when the dwelling unit controller 32 inputs a detection signal while the time measuring unit 36 is measuring time, the dwelling unit controller 31 resets the timing unit 36. Moreover, the dwelling unit controller control unit 31 determines whether or not the time measured by the time measuring unit 36 is equal to or longer than a predetermined time, and indicates that an abnormality has occurred in the resident when the time is longer than the predetermined time. Generate an error report signal. When the carrying determination unit 35 determines that the resident is carrying the wireless slave device 1 (for example, the state shown in FIG. 1), the generated abnormality notification signal is transmitted to the management room by the dwelling unit controller interface 32. It is output to the base unit 40. On the other hand, when the carrying determination unit 35 determines that the resident is not carrying the wireless slave device 1 (for example, the state shown in FIG. 3), the generated abnormality notification signal is not output. Here, information for identifying a room or a resident is added to the abnormality notification signal.

  In addition, when the absence determination unit 34 determines that it is absent, the following operation is performed. The dwelling unit control unit 31 checks whether or not the dwelling unit control unit interface 32 has input a detection signal. When the dwelling unit control unit 31 determines that the dwell unit control unit interface 32 has input the detection signal, the dwelling unit control unit 31 determines that there is an intruder in the room (for example, FIG. 4). In the state shown in FIG. 9), an abnormality notification signal different from the abnormality notification signal described above is generated. The generated abnormality notification signal is output to the management room base unit 40 by the dwelling unit controller interface 32. Here, the case where the human sensor 20 detects the movement of the person in spite of the absence is not only the case where there is an intruder in the room, but the battery built in the wireless slave unit 1 is consumed. It is also possible to run out. This is because when the battery built in the wireless slave unit 1 is exhausted, the reception level at which the receiver 10 receives the transmission signal becomes less than a predetermined value.

  The management room base unit 40 is installed in a management room or the like, and is used by a manager to monitor the status of each room in the management room. The management room base unit 40 includes a base unit control unit 41, a base unit interface 42, and a notification unit 43. The base unit control unit 41 controls each component of the management room base unit 40. The base unit interface 42 is used to connect the management room base unit 40 and the dwelling unit controller 30 and is connected to the dwelling unit control unit interface 32 by wire. Then, the base unit interface 42 inputs an abnormality notification signal from the dwelling unit controller 30.

  The alerting | reporting part 43 alert | reports that abnormality generate | occur | produced in the resident (or living room). Here, the notification unit 43 includes a sound emitting device such as a speaker and a display device such as a liquid crystal display. In addition, when notifying that the abnormality has occurred in the notification unit 43, information on the target resident (or room) may be displayed on the display device by the identification information included in the abnormality notification signal. good. The base unit control unit 41 operates the notification unit 43 when the base unit interface 42 receives an abnormality notification signal. Upon receiving this notification, the manager confirms the status of the room.

  As described above in detail, according to the present embodiment, the human sensor 20 that detects the movement of a person in the living room and the transmission signal received from the wireless slave device 1 carried by the resident, the reception level thereof is received. The presence / absence determination unit 34 determines that the resident is absent when the value of the reception level is less than a predetermined value, and the presence / absence determination unit 34 determines the reception level. The presence / absence determination unit 34 determines that the resident is in the room when the value of is greater than or equal to a predetermined value. On the other hand, the reception level value acquired by the receiver 10 is measured by the measurement unit 13 every predetermined time, and when the human sensor 20 detects the movement of the person, the latest stored in the reception level storage unit 33 When the value of the reception level is compared with the value of the reception level immediately before it is determined that there is no change, the carrying determination unit determines that the resident is not carrying the wireless slave unit 1. Then, when it is determined that the user is in the room and the resident is determined to carry the wireless slave device 1, an abnormality is reported to the administrator.

  Thereby, even if the human sensor 20 detects the movement of the person, if the value of the reception level from the wireless slave unit 1 does not change from before the detection, the resident and the wireless slave unit 1 are in the same place. Since it is determined that it does not exist, it is possible to determine whether or not the resident is carrying the wireless slave device 1. When it is determined that the value of the reception level from the wireless slave unit 1 is equal to or greater than a predetermined value, it is determined that the resident is in the room and the resident is carrying the wireless slave unit 1. When the human sensor 20 does not detect the movement of the person for a predetermined time or more, the manager is notified that there is an abnormality in the resident, so whether the resident is carrying the wireless handset 1 or not. It is possible to report the abnormality in the room to the manager after determining whether or not.

  In the above-described embodiment, the resident cannot be aware that the wireless slave device 1 is not carried, but the present invention is not limited to this. For example, the dwelling unit control unit 31 generates warning information for encouraging the wireless slave device 1 to be carried when the carrying determination unit 35 determines that the resident is not carrying the wireless slave device 1. You may make it transmit to the apparatus 1. FIG. Here, the wireless slave device 1 has a function of receiving warning information and a function of notifying warning information. Thereby, the resident who is not carrying the wireless slave device 1 can grasp that the wireless slave device 1 is not carried by notifying the warning information. Usually, the warning information can be confirmed by a resident in the room.

  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.
