The staff terminal 34 connects with other devices via the wireless AP 35 . Further, each device in the nursing care facility 900 is connected to the Internet via an RT (router).

(Detector 31)
FIG. 6 is a diagram showing an example of the detector 31 installed around the bed 60 in the room of the resident 70. As shown in FIG. The detection unit 31 is arranged in each room (also called a sensor box) so as to monitor the room of the resident 70, which is an observation area. The detection unit 31 includes various sensors as described later, and generates sensing information from outputs of the sensors. Sensing information includes not only the signal of each sensor but also, for example, the determination result of a person's movement determined by image processing from a video signal (event described later) and a care call signal from the care call unit 314 (described later).

FIG. 7 is a block diagram showing a schematic configuration of the detector 31. As shown in FIG. As shown in FIG. 7, the detection unit 31 includes a control unit 311, a communication unit 312, a camera 313, a care call unit 314, an audio input/output unit 315, and a pause switch 316, which are connected by bus or short-range wireless communication. , are interconnected.

The control unit 311 has a configuration similar to that of the control unit 210, such as a CPU, a RAM, and a ROM. Also, the control unit 311 may include an HDD. The control unit 311 controls each unit of the detection unit 31 and performs arithmetic processing according to a program. The control unit 311 functions as an event determination unit 31a.

The communication unit 312 is an interface circuit (for example, a LAN card, a wireless communication circuit, etc.) for communicating with other devices such as the watching device 32 via a LAN.

The camera 313 is arranged, for example, on the ceiling or the upper part of the wall of the living room, photographs the bed 60 of the resident 70 directly below as an observation area, and outputs a photographed image (image data). The captured images include still images and moving images. The camera 313 is a near-infrared camera, but a visible light camera may be used instead, or both of them may be used. The camera 313 outputs an image signal as sensing information acquired by the imaging sensor.

The care call unit 314 includes a push-button switch, which is operated by the resident 70 to detect a care call (also referred to as a nurse call). A voice microphone may be used to detect a care call instead of the push-button switch. When the switch of care call unit 314 is pressed, that is, when a care call is detected, control unit 311 transmits a notification that there is a care call to watching device 32 or the like via communication unit 312 and LAN.

The voice input/output unit 315 is, for example, a speaker and a microphone, and enables voice communication by transmitting and receiving voice signals to and from the terminal device 33 and the staff terminal 34 via the communication unit 312 . Note that the voice input/output unit 315 may be connected to the detection unit 31 via the communication unit 312 as an external device of the detection unit 31 .

A pause switch 316 is arranged near the doorway of the living room. The temporary stop switch 316 includes a push-button type switch, and when the staff member 72 or the like enters the living room, operating this switch causes the determination processing by the event determination unit 31a of the detection unit 31 to be described below. Temporarily suspended.

In event determination processing, which will be described later, the event determination unit 31a of the control unit 311 determines an event based on the movement of the resident 70 based on the captured image. In this case, when a third party such as a staff member 72 other than the resident 70 enters the living room, the control unit 311 side cannot distinguish between the resident 70 and the third party, and the action of the third party is detected. There is a possibility that the behavior of the resident 70 may be regarded as an unintended event determination. That is, there is a risk of false alarms occurring. To prevent this, a pause switch 316 is utilized. It should be noted that the temporary stop switch 316 may be replaced with a push button type, or may be combined with an NFC (near field communication) type sensor such as FeliCa (registered trademark). For example, the temporary stop switch is turned ON/OFF by holding an IC card possessed by the staff member 72 over a reading terminal arranged at the doorway of the living room. By operating the temporary stop switch, the event determination process is temporarily stopped, but this cancellation is performed by operating the temporary stop switch again. It should be noted that it may be automatically canceled after the elapse of a predetermined time according to a preset setting by the staff member 72 or the like.

The detection unit 31 may further include a body motion sensor, a bed sensor, a mat sensor, a thermal sensor, or an infrared sensor as other sensors for detecting nursing care data. This body motion sensor may be a Doppler shift type sensor that transmits and receives microwaves to and from the bed 60 and detects the Doppler shift of the microwaves caused by body motion (for example, respiratory motion) of the resident 70 . This body motion sensor detects the body motion of the chest (up and down motion of the chest) associated with the breathing motion of the resident 70 . When the disturbance of the cycle of the chest body movement or the amplitude of the chest body movement that is equal to or less than a preset threshold value is detected, it is determined that there is an abnormal micromotion (for example, due to cardiac arrest). The determination of the abnormality in microbody motion may be performed by the detection unit 31 side, or may be performed by the control unit 110 of the information processing device 10 by sending only a signal to the information processing device 10 . This bed sensor may be a sensor that is attached to the bed. may be detected, or a sleeping state may be detected. This infrared sensor is also called a human sensor, and detects whether or not there is a person in the living room. For example, the entire living room or the top of the bed 60 is arranged as the observation area.

(Event judgment by image processing)
In the present embodiment, as described above, the change in the state detected by the detection unit 31 regarding the resident 70 requires care for the resident 70, such as getting up, getting out of bed, falling, abnormal micromovement, etc. An event that should be notified to the staff member 72 is called an event. This event also includes a care call by the care call unit 314 . The detection unit 31 transmits the determination result of the occurred event to the watching device 32 .

The event determination unit 31 a of the control unit 311 detects the behavior of the resident 70 from the captured image captured by the camera 313 . The behaviors to be detected include "getting up" from the bed 60, "getting out of bed" from the bed 60 after getting up, "falling" from the bed 60, and "falling" to the floor or the like.

The event determination unit 31a detects image silhouettes (hereinafter referred to as “human silhouettes”) from a plurality of captured images (moving images). A human silhouette can be detected, for example, by extracting a range of pixels having a relatively large difference based on a time difference obtained by subtracting images captured at different times. A person silhouette may be detected by a background subtraction method in which a background image is subtracted from a captured image. It is assumed that the resident 70 is in the room by detecting a person silhouette.

Also, the area within the rectangle circumscribed by the contour of the image of the resident 70 can be detected as the human rectangle circumscribed by the contour of the image of the resident 70 . In addition to or instead of the person silhouette obtained from the full image of the person, the silhouette of the head image of the resident 70 (hereinafter referred to as "head silhouette") may be detected. A region within the rectangle circumscribing the contour of the head image of the resident 70 can be detected as the head rectangle circumscribing the contour of the head image of the resident 70 in the captured image.

The detection of getting up, leaving the bed, falling, and falling is performed based on the posture of the resident 70 (for example, standing, sitting, lying down, etc.) from the detected human silhouette, and from the position relative to the installation in the living room such as the bed 60. , "getting out of bed" and "falling" are detected. For example, "getting up" can be recognized by the fact that the width of a person's silhouette crossing any side of a preset quadrangle with the four corners of the bed 60 as vertices has increased to 20 cm or more. Also, for example, "getting out of bed" can be recognized when the ratio of the outside area of the person silhouette to the inside of the rectangle increases to 80% or more. Further, when determining the sitting position, it may be recognized whether the sitting position is a sitting position near the side of the bed 60 (at the time of sitting on the edge). When the event determination unit 31a of the detection unit 31 detects any type of event such as getting up, getting out of bed, or falling, the event determination unit 31a transmits event information indicating that the event has occurred to the watching device 32 or the like.

Such event determination processing by the event determination unit 31a may be performed by a program processed by the CPU of the control unit 311, or may be performed by a built-in processing circuit. As another example, as described above, the monitoring device 32 (control unit 321) may perform all or most of these detection processes. In this case, the control unit 311 of the detection unit 31 only transmits the photographed image (data related to nursing care) to the monitoring device 32, and the monitoring device 32 that receives this detects the event based on the photographed image. .

When the notification unit 32a receives event information from the detection unit 31, the notification unit 32a notifies the staff member 72 who takes care of the resident 70 who caused the event (see step S150 in FIG. 11 described later). The notification setting unit 32b sets ON/OFF of the notification for each room (for each observation area) according to the setting by the user (for example, the administrator 74). When the notification is set to OFF, the notification unit 32a does not notify the staff member 72. FIG. The notification setting procedure will be described later (FIGS. 14 and 15 to be described later).

The image data (photographed images i010 to i013) included in the event information is data of still images obtained by photographing by the detection unit 31 when the event occurs, which is transmitted in step S130. The "response status" includes status, response staff, response date (time), live image (hereinafter simply referred to as moving image) viewing or not (use of captured image), and room visit or not. The corresponding staff is a staff member who has taken the initiative in the process of step S180, which will be described later. Here, "visiting the room" means an act of visiting the living room of the resident 70 who caused the event.

(Step S150)
Here, the notification unit 32a of the watching device 32 notifies one or more staff members 72 of the event information newly acquired in step S120. In addition, referring to the notification setting of the storage unit 323, if the room in which the event occurred is set to notification OFF (all OFF), or if the specific event type (see FIG. 15B described later) is set to notification OFF , does not notify the corresponding event. When the notification is set to ON, based on the event information, simultaneous notification to the staff terminals 34 of all logged-in staff members 72 belonging to the unit in charge of the resident 70 is performed. If the notification is OFF and no notification is made, the number of notifications is not counted. When notification is ON and notification is made, the number of notifications is counted as one. Note that FIG. 11 shows only the processing of one staff terminal 34 used by one staff member 72 among the plurality of staff terminals 34 .

(Steps S160, S170)
Each staff member 72 confirms the event that has occurred through the staff terminal 34 . 13A and 13B are examples of operation screens d1 and d2 for responding to an event notification (broadcast notification) displayed on the display unit 343 of the staff terminal 34. FIG. The operation screen d1 shown in the figure is a screen on which an event list is displayed. Events to be displayed can be scrolled up and down by flicking.

Areas a10 to a12 of the operation screen d1 correspond to event IDs 010 to 013 of the event list in FIG. Area a10 displays an icon indicating that event ID010 is a care call and that the event has been dealt with. Area a11 displays an icon indicating that event ID011 is a wake-up event and that the event has already been dealt with. Area a12 displays icons indicating wake-up event and bed-leaving event for event IDs 012 and 013, and indicates that they are not supported. Since these two events relate to the same resident 70 (Mr. C), they are collectively displayed in the same area. Also, since it is not supported, a thumbnail image (image i013) relating to the latest event (ID013) is displayed in the area a13. Text messages can be exchanged with other logged-in staff members 72 by operating the area a13. The staff member 72 clicks on the area a12 on the operation screen d1 to transition to the next operation screen d2 for confirming the contents.

(Step S170)
The staff member 72 confirms the details of the event using the operation screen d2 displayed on the staff terminal . On the operation screen d2, the name of the resident (Mr. C) who caused the occurrence (judgment) of the event and the name of the staff member (staff D) who uses the staff terminal 34 are displayed in an area a20. The area a21 displays the elapsed time from the occurrence time of the event. The elapsed time (“elapsed 1 minute”) shown in area a21 is the elapsed time (rounded down to the nearest minute) after the occurrence of the latest event is determined. In the area a21, a thumbnail image (still image) of the captured image at the time of the event (getting out of bed) determination is displayed. When the staff member 72 wants to check the situation of the resident 70 who caused the event of getting out of bed or getting up because the thumbnail image is not enough information, the staff member 72 can click the "talk" button or the "view" button in the lower areas a23 and a24. to operate. By operating the “Talk” button, the user can talk with the resident 70 (Mr. C) through the voice input/output unit 315 . By operating the "view" button, a display request is transmitted to the watching device 32, and in response to this, a live image (real-time captured image (moving image)) captured by the camera 313 is streamed on the operation screen d2. You can watch it by playback. When the "view" button is operated, as shown in the movie viewing column of the event list in FIG. 12, "presence" of movie viewing is recorded for this event. At this time, in association with the event, the video viewing time and the number of calls/call time via the "talk" button may be recorded.

The staff member 72 (for example, staff member D) takes the initiative in taking charge of getting up and leaving the bed (ID012, 013) displayed by operating the "correspondence" button (hereinafter also referred to as "response request") in the area a22. hope to If not, the back button (triangular icon) in the bottom column is operated to return to the previous operation screen d1 showing the event list. While a certain staff member 72 is displaying the operation screen d2 shown in FIG. 13 and confirming the state of the event, the monitoring device 32 controls the other staff member 72 to perform a prohibition process. For example, even if another staff member 72 selects the same event (ID013) while a certain staff member 72 is confirming the event status of the resident 70 (Mr. C), the other staff member 72's operation screen d1 will show , and the characters "Confirming status" are displayed, and the "Correspond" button is not displayed or cannot be selected even if the operation screen d2 is displayed.

(Steps S180, S190)
Staff D operates the "correspond" button (depresses the corresponding button) when he or she wishes to take the initiative in taking charge of the event. The staff terminal 34 transmits a charge request for the selected event to the watching device 32 in response to the operation of the "correspond" button by the staff D who is the terminal user. In response, the watching device 32 returns an approval notification. Upon approval, the staff member D, who has sent the charge request, becomes the person in charge of the event, checks the status of the event through the staff terminal 34, and rushes to the event (visiting the room) if necessary.

(Step S200)
The watching device 32 updates the event list according to the process of step S180. Specifically, the status of the event list (ID012 to 013: getting out of bed, etc.) is changed to handled. In the present embodiment, the event selected by the staff 72 and displayed on the operation screen d2 is changed to "handled" in response to the operation of the above-described "handle" button. That is, by operating the "Response" button, the response status of "Responded", which is information indicating confirmation, is input, and it is assumed that the staff member 72 who operated the button has responded, and the date and time of response is recorded. do. More specifically, in the event list of FIG. 12, the time when the process of step S180 or S190 was performed is recorded in the corresponding date/time column. In this case, by confirming the thumbnail image on the operation screen d2 or talking with the resident 70, the response may be terminated without rushing to respond. Note that the response date and time is not limited to this, and is the time when the staff 72 decides to visit the room of the resident 70 who caused an event such as a fall, a fall, a nurse call, etc. , may be recorded in the corresponding date and time column. Further, as another example, the correspondence result may be entered through another operation screen to complete the correspondence, and the input time may be recorded in the correspondence date and time column. In addition, when the event list is updated, the watching device 32 broadcasts the updated event list to all logged-in staff members.

(Step S210)
Here, an example of a case in which rushing is performed will be described. A staff member 72 in charge of the event visits the resident 70 who caused the event as a rush response.

(Step S220)
By operating the pause switch 316 or by detecting a third party other than the resident 70 based on the image captured by the camera 313, the detection unit 31 (event determination unit 31a) of the living room detects a plurality of By detecting the presence of a person, it is determined that the staff member 72 has visited (entered) the room. At this time, if the room where the event occurred is visited within a predetermined period of time (for example, within 10 to 15 minutes) after the request for response to the event (S180), the staff member who made the request for response It is assumed that 72 (Staff D) visited the room. In addition, when using an NFC reading terminal placed at the entrance of the living room as the temporary stop switch 316, the staff member 72 holds up an IC card in which ID data is recorded to the reading terminal, thereby allowing the visit to the room to be terminated. You may make it determine whether it happened and which staff member 72 visited the room.

(Step S230)
The detection unit 31 transmits information about the staff's visit to the room to the monitoring device 32 . The room visit information includes the ID number of the resident 70 .

(Step S240)
The monitoring device 32 records the room visit information received in step S230 in association with the event of which the status of the resident 70 corresponding to the ID number is completed and the date and time of response is the latest. For example, in the event list of FIG. 12, the room visit column of the response status of the corresponding event ID is updated to "Yes".

(Step S250)
The staff member 72 logs out by operating a button (not shown) of "end of work" on the staff terminal 34 at the end of work. The logout time is recorded in the storage unit 323 as shift information.

(Notification settings)
Next, notification settings will be described with reference to FIGS. 14 and 15. FIG. FIG. 14 is an example of an operation screen d3 for notification settings, and FIG. 15 is a diagram showing notification settings stored in the storage unit 323 and types of notification settings. The operation screen d3 of FIG. 14 is displayed on the display unit 333 of the terminal device 33. FIG. The administrator 74 can set notification ON/OFF by clicking the bell icon i01 provided corresponding to the display of each room on the operation screen d3. Notification settings are stored in the storage unit 323 . In the operation screen d3 of FIG. 14, rooms 101, 104, 105, etc. are set to notification OFF and displayed in gray. Other rooms (rooms 102, 103, etc.) are set to notification ON. This notification setting is stored in the storage unit 323 in a form as shown in FIG. 15(a). In addition, although the example of FIG. 14 shows an example in which two-step setting of ON/OFF is performed, multi-step setting may be performed. FIG. 15B is an example of setting in multiple stages. Notification ON/OFF for each event of getting up, getting out of bed, and falling can be set individually. For example, in notification setting 7, the notification is OFF for getting up and getting out of bed, and the notification is ON for falling. In this case, the staff member 72 in charge is notified of the falling event, while the other events of getting up and getting out of bed are not notified. For example, for a resident 70 who has a low level of care and is able to walk independently, the notification setting is set to 8 (all OFF). Setting 1 (all ON), intermediate notification setting 5 (wake-up notification OFF), or the like is set.

In addition, on the operation screen d3, the state of the resident 70 (state, breathing rate, heart rate) obtained from the sensing information of the detection unit 31 is displayed so that the staff 72 and the administrator 74 can grasp the situation of each room at once. is shown. Based on the sensing information of the camera 313, room 102 is in a wake-up state (wake-up event), room 202 is in a sitting state, room 301 is in a bed-out state (bed-out event), and room 304 is in a sleeping state. ing. In addition, in a sleeping or waking state, lying on the bed 60 (room 102, etc.), the heart rate and respiration rate are indicated based on the sensing information of the body motion sensor.

(Operation log data and operation status)
As described above, the monitoring device 32 acquires sensing information related to nursing care from each device of the nursing care facility 900 , generates operation log data from this information, and stores it in the storage unit 323 . Again, refer to FIG.

(Operation log data)
The operation log data is data representing the operating state of each device of the watching support system 30 (devices existing in the nursing care facility 900). As shown in FIG. 3A, the operation log data includes notification settings for each room (x1), event notifications (x2), login/logout (x3), and corresponding button press information (x4).

x1: The notification setting is ON/OFF setting of event notification for each room, which is set by the notification setting unit 32b as shown in FIGS.

x2: Event notification corresponds to step S130 (or step S150) in FIG. 11 described above. This is a notification to the staff terminal 34 regarding an event requiring care of the resident 70 detected by sensing information from the camera 313, the event determination unit 31a, the care call unit 314, and the notification unit 32a. This notification is associated with event information (event ID, event type, date and time of occurrence, etc.) and recorded in the event list.

x3: Login/logout is performed by the staff terminal 34 corresponding to steps S100 and S250 in FIG. 11 described above. This signal corresponds to the start and end times of work of the staff member 72 who uses this staff terminal 34, and is stored in the storage unit 323 as shift information.

x4: Corresponding button pressing information corresponds to step S180 in FIG. The response button pressing information is a "response request" of the staff member 72, and is recorded in the event list in association with the event information.

(Operating status)
Based on the operation log data accumulated in the storage unit 323, the analysis unit 112 of the information processing device 10 calculates (quantifies) at least one of the operation states a1 to a4 shown in FIG. to analyze.

a1 (notification number change rate): The analysis unit 112 calculates the notification number change rate using the operation log data (x2: event notification). As for the number of notifications, the number of notifications for this month (per day, per room) and the number of notifications for last month are calculated for a predetermined period (one month). Then, the change over time is analyzed by calculating the ratio of the number of notifications this month to the number of notifications last month. Also, if there is an increase or decrease that exceeds a certain range, for example, if 50 to 200% is applied as a certain range, if it is less than 50% or more than 200%, the analysis unit 112 will generate an alert (utilization is low).

a2 (percentage of all notifications ON): The analysis unit 112 calculates the percentage of all notifications ON (notification ON rate) based on operation log data (x1: notification settings) and service contract information (the room in which the detection unit 31 (sensor) is installed). number). In addition, when the recent (at present) notification ON rate exceeds a certain value or is less than a certain value, the analysis unit 112 issues an alert indicating that the monitoring support service is not being properly used. low) may be determined.

a3 (notification OFF rate): This notification OFF rate is used when notification OFF can be set in multiple stages, as in the example shown in FIG. 15B. The analysis unit 112 calculates the ratio of the number of notification OFF settings to the set value (number of rooms×number of notification types) obtained by multiplying the number of rooms for which the detection unit 31 is set by the number of notification OFF setting types (three). For example, in the example shown in FIG. 15B, in the case of notification setting 5, the number of notification OFF settings in one room is 1 (only waking up is OFF), 2 in the case of notification setting 7, and notification setting 8 In that case, it will be 3. Similarly, when the recent (current) notification OFF rate exceeds or is less than a certain value, the analysis unit 112 alerts (uses) that the monitoring support service is not properly used. degree is low).

a4 (response time increase/decrease rate): The analysis unit 112 calculates the response time using the operation log data (x2 (event notification), x4 (response button pressing information)). This response time corresponds to the elapsed time from step S150 (notification) to step S180 (responsible request) in FIG. The analysis unit 112 calculates the average response time (per notification) for this month and the average response time for the last month for a predetermined period (one month). Then, the change over time is analyzed by calculating the ratio of the average response time value for this month to the average response time value for the previous month. Also, if there is an increase or decrease that exceeds a certain range, for example, if 50 to 200% is applied as a certain range, if it is less than 50% or more than 200%, the analysis unit 112 will generate an alert (utilization is low). For example, if it becomes extremely short, it is possible that the corresponding button was simply pressed without checking the contents of the event, and if it becomes extremely long, the corresponding button may not be used. question the sex.

(Analysis processing of operation status)
Next, with reference to FIG. 16, the operation status analysis processing based on the operation log data described above will be described. FIG. 16 is a flow chart showing the operation status analysis process.

The control unit 110 determines whether or not it is time to analyze. For example, every predetermined day such as every month, or when there is a request from the terminal device 20 (employee 76), it is determined that the analysis will be performed (YES), the process proceeds to step S340, Otherwise (NO), the processing from step S310 is repeated.

(Step S340)
The analysis unit 112 analyzes the operating status of one or a plurality of nursing care facilities 900 at the analysis timing. Specifically, the analysis unit 112 analyzes the current operating status (for example, a2 and a3 in FIG. 3B). In addition, the analysis unit 112 analyzes temporal changes in operating conditions (for example, a1 and a4 in FIG. 3B).

(Step S350)
The analysis unit 112 determines whether the operating status or the temporal change in the operating status is outside a predetermined range. For example, if the notification ON rate (a2) exceeds a certain value, or if the ratio of the number of notifications this month (a1) to the number of notifications last month is not outside a certain range (NO), the process proceeds to step S360. proceed. On the other hand, if it is outside the predetermined range (YES), the process proceeds to step S370.

(Step S360)
The output unit 113 outputs the analysis result of the operation status. For example, the output unit 113 transmits analysis results to the terminal device 20 . The employee 76 arranges and displays a plurality of operation status data of each nursing care facility 900 on the dashboard displayed on the display unit 230 of the terminal device 20 . For example, the service provider (employee 76, etc.) can grasp the degree of utilization of the monitoring support service in a specific nursing care facility 900 by referring to the dashboard.

(Step S370)
As in step S360, the analysis result of the operation status is output. Furthermore, the analysis unit 112 includes an alert, that is, the low utilization of the monitoring support service of the monitoring support system 30 and a high possibility of withdrawal in the analysis result. The output unit 113 outputs this alert together with the analysis result. As an example of outputting an alert, it is possible to output a response method as a report together, and highlight the corresponding item (item of operation status) with color, marking, etc. so that it can be distinguished from other items. may In this case, the analysis results of the operation statuses of a plurality of nursing care facilities 900 may be displayed as a list. The service provider can read through the dashboard displayed on the display unit 230 that the degree of utilization of the monitoring support system has decreased and that some kind of trouble has occurred. Then, the possibility of withdrawal from the monitoring support service of the nursing care facility 900 can be grasped, and measures can be taken to prevent withdrawal according to the cause.
