  Hereinafter, the care system of this embodiment will be described with reference to FIG. FIG. 6 is a flowchart showing a flow of an abnormal action notification of a person requiring assistance in the care system of the present embodiment. In addition, the care system of this embodiment is related with the care system in which the 2nd communication apparatus 20 which a caregiver possesses detects the abnormal action of the assistance person outside a residence facility, and control of the 2nd communication apparatus 20 is carried out. If the processing capability of the unit 21 is taken into consideration, it is assumed that a caregiver assists a person who needs assistance on a one-on-one basis, such as home care, or a small number of caregivers.

  In step S <b> 01, the control unit 11 determines whether or not the current position of the own device 10 (in other words, a person requiring assistance who owns the own device 10) is outside the residential facility (home). The determination of whether or not the current position is outside the residential facility may be based on positional information specified based on the GPS signal received by the GPS signal receiving unit 12, or the first communication device 10 may be in the residential facility. If you are connected to a home network in the home, it is based on the connection status with the home network (that is, if you are not connected to the home network, the current location is determined to be outside the residential facility) Good. If the current position of the own device 10 is outside the residential facility (Y in step S01), the process proceeds to step S02, and if the current position of the own device 10 is in the residential facility (N in step S01), the process returns to step S01.

  In step S02, the control part 11 calculates the positional information of the own apparatus 10 based on the GPS signal which the GPS signal receiving part 12 receives, and transfers to step S03. In step S01, if it is determined whether or not the current position of the device 10 is outside the residential facility based on the GPS signal received by the GPS signal receiving unit 12, the position information is specified in this step. Therefore, the process of step S02 may be omitted.

  In step S03, the control unit 11 transmits the position information calculated in step S02 to the base station via the communication unit 13, and returns to step S01. In this step, the control unit 11 may transmit the position information of the own device 10 to the base station and store the position information of the own device 10 in the storage unit 14. The processing of steps S01 to S03 by the control unit 11 is repeated until the current position of the own device 10 is in the residential facility.

  In step S11, the control unit 21 determines whether or not the communication unit 22 has received the position information of the first communication device 10 via the base station. If the communication unit 22 has received the position information of the first communication device 10 via the base station (Y in step S11), the process proceeds to step S12, and the communication unit 22 passes the base station through the first communication device. If position information 10 is not received (N in step S11), the process returns to step S11. In step S12, the control unit 11 stores the position information of the first communication device 10 received by the communication unit 22 in step S11 in the storage unit 23, and proceeds to step S13.

  In step S <b> 13, the control unit 21 stores the change pattern of the position information of the first communication device 10 stored in the storage unit 23 and the position information associated with the abnormal behavior mode stored in the storage unit 23. By comparing with the change pattern, it is determined whether or not the change pattern of the position information of the first communication device 10 corresponds to the abnormal behavior mode. When the pattern of change in position information of the first communication device 10 corresponds to the abnormal behavior mode (Y in step S13), the process proceeds to step S14, and the pattern of change in position information of the first communication device 10 is abnormal behavior. When it does not correspond to an aspect (N of step S13), it returns to step S11.

  In step S14, the control unit 21 controls the notification unit 24 within a predetermined time before the current time, and performs a predetermined notification regarding the communication device (first communication device 10 in the present embodiment) corresponding to the abnormal behavior mode. It is determined whether or not. The determination in this step is performed based on the notification history information stored in the storage unit 23. In the notification history information, at least communication device information corresponding to the abnormal action mode (identification information unique to the communication device may be used, or the name of a person who needs assistance may be included), And the time information which performed alerting | reporting is contained, and the type information of an abnormal action aspect may be contained in addition. If the notification unit 24 is controlled within the predetermined time before the current time to perform the predetermined notification regarding the first communication device 10 (Y in step S14), the process returns to step S11, and within the predetermined time before the current time. If the notification unit 24 is not controlled to perform the predetermined notification related to the first communication device 10 (N in step S14), the process proceeds to step S15.

  In step S <b> 15, the control unit 21 determines whether or not the transmission is performed from the second communication device 20 to the first communication device 10 within a predetermined time before the current time. The determination in this step is performed based on the transmission history information stored in the storage unit 23. The transmission history information includes at least communication device information of a transmission destination (may be identification information unique to the communication device or the name of a person who needs the communication device), and transmission In addition, the communication mode (mail communication, call communication, etc.) information, call communication time information, and reply information for mail transmission may be included. If the transmission is made from the second communication device 20 to the first communication device 10 within a predetermined time before the current time (Y in step S15), the process returns to step S11, and the predetermined communication before the current time is performed. If no transmission is made from the second communication device 20 to the first communication device 10 within the time (N in Step S15), the process proceeds to Step S16. The same time may be set as the predetermined time in step S14 and the predetermined time in this step, or different times may be set.

  In step S16, the control unit 21 controls the notification unit 24 to perform a predetermined notification indicating that the person requiring assistance is in an abnormal behavior state. As the predetermined notification performed via the notification unit 24, for example, a predetermined warning sound is generated via the audio output unit, and / or an image such as “the person requiring assistance is dangerous!” Is displayed on the image display unit. indicate.

  In the present embodiment, in order to prevent continuous notification for a short period of time, notification is not performed when there is a notification history within a predetermined time in step S14, and even if there is no notification history. When the person in need is contacted by telephone or the like, it is considered that the current state of the person in need of assistance is grasped. Therefore, in step S15, no notification is given when there is a call history within a predetermined time. However, as a modification, it is good also as a structure which does not provide step S14 and step S15, and the process of step S14 and step S15 in view of the progress degree of a dementia and the degree of care required (acquisition status of care certification) of the person requiring assistance It is good also as a structure which can select whether to perform.

  Further, in step S15, notification is not performed when there is a call history within a predetermined time, but call communication time information (information indicating a time when a call was made with a person who needs assistance) or a reply to mail transmission is included in the call history information. If information (information indicating that a mail reply from a person requiring assistance has been sent in response to a mail transmission to a person requiring assistance) is included, the presence / absence of contact with the person requiring assistance is determined based on that information as well. It is good.

  Moreover, in this embodiment, when the pattern of the positional information change of the first communication device 10 corresponds to the abnormal behavior mode, the control unit 21 controls the notification unit 24 to perform a predetermined notification. In addition, information indicating that the behavior is abnormal behavior may be transmitted to the first communication device 10 via the base station, and the control unit 11 may control the notification unit 15 to perform predetermined notification. The control unit 11 and the control unit 21 may perform the predetermined notification by controlling the notification unit 15 and the notification unit 24, respectively. The predetermined notification performed via the notification unit 15 is preferably a notification indicating that the person requiring assistance is in a dangerous state with respect to a person existing around the person requiring assistance, for example, an audio output unit A predetermined warning sound is output via the, or voice output such as “Please protect” is performed. In addition, an image such as “Dangerous state !!” is displayed on the image display unit.

  According to the present embodiment, notification is performed when the pattern (behavior mode) of change in position information of the person requiring assistance (the communication device possessed by the person requiring assistance) corresponds to the abnormal behavior mode outside the residential facility.

  In this embodiment, the control unit 11 and the GPS receiving unit 12 function as a position information acquisition unit, the control unit 21 functions as an action mode specifying unit and a notification control unit, and the storage unit 23 is an abnormal behavior mode setting unit. Function as.

  In step S21, the control unit 11 determines whether or not the current position of the own device 10 is outside the residential facility. The determination method in this step is the same as that in step S01 in FIG. If the current position of the own device 10 is outside the residential facility (Y in step S21), the process proceeds to step S22, and if the current position of the own device 10 is in the residential facility (N in step S21), the process returns to step S21.

  In step S22, the control unit 11 calculates the position information of the device 10 based on the GPS signal received by the GPS signal receiving unit 12, and proceeds to step S23. In step S23, the control unit 11 stores the position information calculated in step S22 in the storage unit 14, and proceeds to step S24.

  In step S <b> 24, the control unit 11 changes the position information change pattern stored in the storage unit 14 and the position information change pattern associated with the abnormal behavior mode stored in the storage unit 14. Are compared to determine whether or not the pattern of change in the position information of the device 10 corresponds to the abnormal behavior mode. When the change pattern of the positional information of the own device 10 corresponds to the abnormal behavior mode (Y in Step S24), the process proceeds to Step S25, and the change pattern of the positional information of the own device 10 does not correspond to the abnormal behavior mode ( N) of step S24 returns to step S21.

  In step S <b> 25, the control unit 11 transmits information indicating that the behavior mode of the own device 10 corresponds to the abnormal behavior mode within a predetermined time before the current time via the base station to another communication device (the second mode in the present embodiment). It is determined whether or not it has been transmitted to the communication device 20). The determination in this step is performed based on the transmission history information of abnormal behavior information stored in the storage unit 14. The transmission history information of abnormal behavior information includes at least identification information of a communication device to which information indicating that the abnormal behavior mode corresponds (identification information unique to the communication device, or possessing the communication device). And the transmitted time information may be included, and in addition, type information of an abnormal behavior mode may be included. If the abnormal behavior information has been transmitted to the second communication device 20 within the predetermined time before the current time (Y in step S25), the process returns to step S21, and the abnormal behavior information is stored within the predetermined time before the current time. If it has not been transmitted to the second communication device 20 (N in step S25), the process proceeds to step S26.

  In step S <b> 26, the control unit 11 determines whether there is an incoming call from the second communication device 20 within a predetermined time before the current time. The determination in this step is performed based on incoming call history information stored in the storage unit 14. The incoming call history information includes at least identification information of a communication device that is a transmission source (may be identification information unique to the communication device, or the name of an assistant who owns the communication device), and Incoming time information is included, and communication mode (mail communication, call communication, etc.) information, call communication time information, and reply information for mail reception may be included. If there is an incoming call from the second communication device 20 within a predetermined time before the current time (Y in step S26), the process returns to step S21, and an incoming call is received from the second communication device 20 within a predetermined time before the current time. If not (N in Step S26), the process proceeds to Step S27. The same time may be set as the predetermined time in step S25 and the predetermined time in this step, or different times may be set.

  In step S26, it is determined whether or not there is an incoming call from the second communication device 20 within a predetermined time before the current time, but the call communication time information (information indicating the time when the call was made with the assistant is included in the incoming call history information. ) Or reply information for receiving a mail (information indicating that the person requiring assistance has sent a reply to the mail received from the assistant), the presence or absence of an incoming call from the assistant based on the information It may be determined.

  In step S27, the control unit 11 transmits abnormal behavior information to the second communication device 20 via the base station.

  In step S31, the control unit 21 determines whether the communication unit 22 has received abnormal behavior information from the first communication device 10 via the base station. If the communication unit 22 has received abnormal behavior information from the first communication device 10 via the base station (Y in step S31), the process proceeds to step S32, and the communication unit 22 performs the first communication via the base station. If abnormal behavior information has not been received from the device 10 (N in step S31), the process returns to step S31.

  In step S32, the control unit 21 controls the notification unit 24 to perform a predetermined notification indicating that the person requiring assistance is in an abnormal behavior state. The predetermined notification in this step is the same as step S16 in FIG.

  Similar to the first embodiment, as a modification, the configuration may be such that step S25 and step S26 are not provided, and the configuration in which whether or not to execute the processing of step S25 and step S26 may be selected. The control unit 11 may control the notification unit 15 to perform predetermined notification, or the control unit 11 and the control unit 21 may control the notification unit 15 and the notification unit 24, respectively, to perform predetermined notification.

The processing of steps S41 to S43 by the control unit 11 is repeated until the current position of the own device 10 is in the residential facility.

  In step S51, the control unit 31 determines whether or not the communication unit 32 has received the position information of the first communication device 10 via the Internet server. If the communication unit 32 has received the position information of the first communication device 10 via the Internet server (Y in step S51), the process proceeds to step S52, and the communication unit 32 passes the first communication device via the Internet server. If position information 10 has not been received (N in step S51), the process returns to step S51. In step S52, the control unit 11 stores the position information of the first communication device 10 received by the communication unit 32 in step S51 in the storage unit 33, and proceeds to step S53.

  In step S <b> 53, the control unit 31 stores the pattern of the positional information of the first communication device 10 stored in the storage unit 33 and the positional information associated with the abnormal behavior mode stored in the storage unit 33. By comparing with the change pattern, it is determined whether or not the change pattern of the position information of the first communication device 10 corresponds to the abnormal behavior mode. If the pattern of change in position information of the first communication device 10 corresponds to the abnormal behavior mode (Y in step S53), the process proceeds to step S54, and the pattern of change in position information of the first communication device 10 is abnormal behavior. When it does not correspond to an aspect (N of step S53), it returns to step S51.

  In step S54, the control unit 31 sends information indicating that the behavior mode of the first communication device 10 corresponds to the abnormal behavior mode within a predetermined time before the current time to another communication device (in this embodiment, via the Internet server). It is determined whether it has been transmitted to the second communication device 20). The determination in this step is performed based on the transmission history information of abnormal behavior information stored in the storage unit 33.

If abnormal behavior information has been transmitted to the second communication device 20 within a predetermined time before the current time (Y in step S54), the process returns to step S51, and the abnormal behavior information is stored within the predetermined time before the current time. If it has not been transmitted to the second communication device 20 (N in step S54), the process proceeds to step S55.

  In step S55, the control unit 31 transmits abnormal behavior information to the second communication device 20 via the Internet server.

  In step S61, the control unit 21 determines whether or not the communication unit 25 has received abnormal behavior information from the information processing apparatus 30 via the Internet server. If the communication unit 25 has received abnormal behavior information from the information processing device 30 via the Internet server (Y in step S61), the process proceeds to step S62, and the communication unit 25 is abnormal from the information processing device 30 via the Internet server. If action information is not received (N of step S61), it returns to step S61.

  In step S <b> 62, the control unit 21 determines whether or not a transmission has been performed from the second communication device 20 to the first communication device 10 within a predetermined time before the current time. The determination in this step is performed based on the transmission history information stored in the storage unit 23. If the transmission is made from the second communication device 20 to the first communication device 10 within a predetermined time before the current time (Y in step S62), the process returns to step S61, and the predetermined communication before the current time is performed. If no call is made from the second communication device 20 to the first communication device 10 within the time (N in step S62), the process proceeds to step S63.

  In step S63, the control unit 21 controls the notification unit 24 to perform a predetermined notification indicating that the person requiring assistance is in an abnormal behavior state.

  As in the first embodiment and the second embodiment, as a modification, the configuration may be such that step S54 and step S62 are not provided, and whether or not the processing of step S54 and step S62 is executed can be selected.

  The control unit 71 is a control unit that controls the entire communication device 70. The control unit 71 includes a CPU, a ROM, and a RAM (not shown). The ROM stores software and programs executed by the control unit 71, and parameters and data necessary for executing the software and programs. The CPU executes various software and programs stored in the ROM. The RAM temporarily stores data obtained during various processes and data obtained as a result of various processes. These CPU, ROM, RAM and the like are connected via a bus. Note that the CPU, ROM, and RAM may be partially or fully integrated on one chip.

  The communication unit 72 communicates with the sensor network. The storage unit 73 is a storage unit that stores information about the ID tag 50 acquired via the communication unit 72. The information related to the ID tag 50 acquired via the communication unit 72 may include identification information of the ID tag 50 (specific identification information of the ID tag 50, the name of a person who needs the ID tag 50, etc.) The current position information of the ID tag 50 and / or the position information of the human sensor 40 that has read the information from the ID tag 50), and the time when the human sensor 40 has read the information from the ID tag 50. Contains information. Further, the storage unit 73 stores map information, abnormal behavior mode information in which abnormal behavior modes are associated with patterns of change in position information, and notification history information. FIG. 13 is a diagram illustrating an example of map information stored in the storage unit 73. FIG. 14 is a diagram illustrating an example of abnormal behavior mode information stored in the storage unit 73.

  As shown in FIG. 13, the map information includes at least attribute information of each room including the self-room information of the person requiring assistance (position information on the toilet, bath, and living room in FIG. 13).

  As shown in FIG. 14, there are five types of abnormal behavior modes. Note that the types of abnormal behavior modes shown in FIG. 14 are merely examples, and are not limited to these types. The first type is a reciprocating action pattern, for example, an action pattern that moves many times between a living room and a bathroom. The second type is a loop action pattern, for example, an action pattern that goes around a living room, a toilet, and a bath many times. The third type is a stay pattern, which is an action pattern that stays for more than the first set time in a place other than the own room (especially a bathroom and a toilet). The fourth type is a personal room amnesia pattern, which is an action pattern that continues to move outside the personal room even when the current position is in front of the private room or in the private room from the bathroom. The fifth type is a destination amnesia pattern, which is an action pattern that continues to move for a second set time.

  The notification unit 74 is a notification unit that is controlled by the control unit 71 to perform predetermined notification. The control unit 71 controls the notification unit 74 when the action of the person requiring assistance corresponds to an abnormal action.

  Hereinafter, the care system of this embodiment will be described with reference to FIG. FIG. 15 is a flowchart showing the flow of an abnormal behavior notification of a person requiring assistance in the care system of this embodiment.

  In step S71, the control unit 71 determines whether or not the communication unit 72 has received information regarding the ID tag 50 via the sensor network. If the communication unit 72 has received information about the ID tag 50 via the sensor network (Y in step S71), the process proceeds to step S72, and the communication unit 72 has received information about the ID tag 50 via the sensor network. If not (N in step S71), the process returns to step S71. In step S72, the control unit 71 stores information on the ID tag 50 received by the communication unit 72 in step S71 in the storage unit 73, and proceeds to step S73.

  In step S <b> 73, the control unit 71 associates the change pattern of the position information of the ID tag 50 included in the information related to the ID tag 50 stored in the storage unit 73 with the abnormal behavior mode stored in the storage unit 73. It is determined whether or not the pattern of change in the position information of the ID tag 50 corresponds to the abnormal behavior mode by comparing the change pattern of the position information. When the change pattern of the positional information of the ID tag 50 corresponds to the abnormal behavior mode (Y in Step S73), the process proceeds to Step S74, and the change pattern of the positional information of the ID tag 50 does not correspond to the abnormal behavior mode ( N) of step S73 returns to step S71.

  In step S74, the control unit 71 controls the notification unit 74 within a predetermined time before the current time to determine whether or not the predetermined notification regarding the ID tag corresponding to the abnormal behavior mode (the ID tag 50 in the present embodiment) has been performed. Determine. The determination in this step is performed based on the notification history information stored in the storage unit 73. In the notification history information, at least ID tag information corresponding to the abnormal behavior mode (identification information unique to the ID tag may be used, or the name or the like of a person who needs the ID tag), And the time information which performed alerting | reporting is contained, and the type information of an abnormal action aspect may be contained in addition. If the notification unit 74 is controlled within a predetermined time before the current time to perform the predetermined notification regarding the ID tag 50 (Y in step S74), the process returns to step S71, and the notification unit is performed within the predetermined time before the current time. If the predetermined notification regarding the ID tag 50 is not performed by controlling 74 (N in step S74), the process proceeds to step S75.

  In step S75, the control unit 71 controls the notification unit 74 to perform a predetermined notification indicating that the person requiring assistance is in an abnormal behavior state.

  Similar to the first to third embodiments, as a modification, a configuration without step S74 may be provided, and a configuration in which whether or not to execute the process of step S74 may be selected.

  In the present embodiment, the ID tag 50 and the human sensor group are used as a method for specifying the position of the person requiring assistance in the residential facility. However, the present invention is not limited to this. For example, the position of the person requiring assistance may be specified using indoor GPS.

  Further, in the present embodiment, the care recipient needs to carry the ID tag, but it is also possible to carry a communication device as in the first to third embodiments. In that case, it is applicable also to 2nd Embodiment, and it is good also as performing predetermined alerting | reporting by the alerting | reporting part of the communication apparatus which a helper requires.

  According to this embodiment, notification is performed when the pattern (behavior mode) of change in the position information of the person requiring assistance (the communication device possessed by the person requiring assistance) corresponds to the abnormal behavior mode in the residential facility.

  In the present embodiment, the control unit 71 and the communication unit 72 function as a position information acquisition unit, the control unit 71 functions as an action mode specifying unit, and the storage unit 73 functions as an abnormal behavior mode setting unit.

<Supplement>
As a care system, it is good also as performing both abnormal behavior detection outside a residence facility, and abnormal behavior detection inside a residence facility. In that case, regarding the position information of a specific care recipient, the position information in the residential facility and the position information outside the living room are stored in the storage unit as information different from each other, The abnormal behavior is detected by comparing the change pattern of the positional information associated with the abnormal behavior mode determined accordingly.

  Further, in the first to third embodiments, the map information includes safety area information, residential facility information, and location information where a person requiring assistance stops, and in the fourth embodiment, the map information includes own room information. Although the attribute information of each room of each room is included, it may not have such information, or may have only residential facility information or own room information.

  In the former case, it is difficult to determine the fourth type of abnormal behavior shown in FIG. 5, but for example, a high-speed movement pattern may be defined as the fourth type. The high-speed movement pattern includes, for example, a case where the user travels a predetermined distance or more in a short time, for example, when the user gets on a bullet train. Similarly, although it is difficult to determine the fourth type of abnormal behavior shown in FIG. 14, for example, a non-leaving room pattern may be defined as the fourth type. The non-leaving room pattern is a pattern in which the user stays in the room for a predetermined time or more, and the predetermined time is set to a time when there is a possibility that the room has fallen. That is, this type corresponds to, for example, when the user stays in the room for 6 hours or more even though the user should normally leave the room to go to the kitchen or tray regularly.

  Moreover, in this embodiment, although predetermined notification is performed when it corresponds to any of the first type to the fifth type shown in FIGS. 5 and 14, the type of dementia of the person requiring assistance is determined for any type. When the assistant thinks that there is no problem considering the degree of progress and the level of care required (the status of obtaining care certification), or when the situation is known (for example, watching a movie in a movie theater or living room) It may be possible to make settings so that notification is not performed when a part of the category falls under the case of knowing that the vehicle will stay for a long time at a place other than.

  The location information of the first communication device 10 stored in each storage unit, the notification history information, the transmission history information of abnormal behavior information, and the incoming call history information indicate that the current location of the first communication device 10 is within the residence facility. It may be deleted when it becomes. In addition, the position information, notification history information, and transmission history information of the ID tag 50 stored in each storage unit may be deleted when the current position of the ID tag 50 is in the residential facility.
