(overall structure)
FIG. 1 is a diagram illustrating an entire configuration of a watching system according to the present embodiment, and FIG. 2 is a diagram illustrating an example of a detection unit installed around a bed in a room of a subject.

As shown in FIG. 1, the watching system 1 includes a plurality of detection units 10, a server 20, a fixed terminal 30, and one or more staff terminals 40. The server 20 functions as a report output device. These are communicably connected to each other by wire or wireless via a network 50 such as a LAN (Local Area Network), a telephone network or a data communication network. The network 50 may include a repeater that relays a communication signal, such as a repeater, a bridge, a router, or a cross-connect. In the example illustrated in FIG. 1, the staff terminal 40, the detection unit 10, the server 20, and the fixed terminal 30 are mutually connected by a network 50 such as a wireless LAN (for example, a LAN according to the IEEE 802.11 standard) including an access point 51. Connected for communication.

The watching system 1 is provided at an appropriate place according to the target person 70. The target person 70 (also referred to as a watching target person or a care target person) may be, for example, a patient who needs nursing due to illness or injury, a cared person who needs nursing care due to a decline in physical ability due to aging, or a single person living alone. A single person. In particular, from the viewpoint of enabling early detection and early coping, the target person 70 may be a person who needs to be detected when a predetermined inconvenient event such as an abnormal state occurs in the person. For this reason, the watching system 1 is suitably installed in buildings such as hospitals, welfare facilities for the elderly, and dwelling units, depending on the type of the subject 70. In the example illustrated in FIG. 1, the watching system 1 is arranged in a facility including a plurality of rooms (rooms) where a plurality of subjects 70 enter and a plurality of rooms including a nurse station.

The detection unit 10 is arranged in each living room, which is the observation area of the subject 70. In the example illustrated in FIG. 1, the four detection units 10 are arranged in the rooms of the subjects 70, A, B, C, and D, respectively. The bed 60 is included in the observation area of the detection unit 10. Staff 80 (also referred to as care staff or care staff) who provide nursing or care for the subject 70 carries a staff terminal 40 which is a portable terminal. However, the position, the number, and the like of each component included in the watching system 1 are not limited to the example illustrated in FIG. For example, the server 20 may not be located at the nurse station, and may be an external server unit connected to the network 50. Further, the fixed terminal 30 may be omitted, and the server 20 or the staff terminal 40 may perform the function.

(Detection unit 10)

The control unit 11 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), and a memory such as a ROM (Read Only Memory), and performs control and arithmetic processing of each unit of the detection unit 10 according to a program. Note that the control unit 11 may further include an HDD (Hard \ Disk \ Drive) as a memory.

The communication unit 12 is an interface circuit (for example, a LAN card) for communicating with another device such as the server 20, the fixed terminal 30, or the staff terminal 40 via the network 50.

The camera 13 is arranged, for example, on the ceiling of a living room or on an upper part of a wall, and captures an area including the bed 60 of the subject 70 directly below as an observation area, and outputs a captured image (image data). This photographed image includes a still image and a moving image. Although the camera 13 is a near-infrared camera, a visible light camera may be used instead, or these may be used in combination.

The control unit 11 determines (recognizes) the occurrence of a predetermined action of the target person 70 from the image captured by the camera 13. The predetermined actions to be determined include “wake up” rising from the bed 60, “leaving off” from the bed 60, “falling” falling down from the bed 60, and “falling down” falling on the floor or the like.

The control unit 11 detects an image silhouette (hereinafter, referred to as a “human silhouette”) from a plurality of captured images (moving images). The human silhouette can be detected by, for example, extracting a range of pixels having a relatively large difference by a time difference method of extracting a difference between images whose shooting time is before and after. The human silhouette may be detected by a background difference method that extracts a difference between the captured image and the background image. Whether the user is awake, awake, falls, or falls is recognized based on the posture of the subject 70 (for example, standing, sitting, lying down, etc.) based on the detected human silhouette, and the relative position with respect to an installed object such as a bed 60 in a living room. Is done. Such recognition may be performed by a program processed by the CPU of the control unit 11, or may be performed by a built-in processing circuit. In the following, a description will be given assuming that the control unit 11 determines the type of event and whether or not the event has occurred. However, the present invention is not limited to this, and the server 20 may perform all or most of these recognitions, and the control unit 11 may transmit only the captured image to the server 20. When recognizing any type of action, the control unit 11 transmits a notification to the effect that the action (an event to be described later) has occurred to the server 20 or the like.

The staff 80 is a person who performs various responses to the target person 70 according to the business. Services can include medical services and nursing care services. Here, in the case where the work of the staff 80 is a care work for the target person 70, the corresponding contents regarding each event will be described. "Waking up" is determined as an event, and if the determination is within a predetermined time (wake-up time set at the facility (for example, 7 to 8 am), morning care is performed. This morning care includes face washing, tooth brushing assistance, denture wearing, changing clothes assistance, and the like. In addition, in the event of “leaving out of bed”, a wheelchair transfer or walking assistance may be required. In addition, as a regular (regular) event other than the event determined by the detection unit 10, there are drinks, meal assistance, excretion assistance, wheelchair transfer, walking assistance, and posture change (pressure ulcer prevention). For these regular events, an alert may be generated at a fixed time by the nurse call unit 14 or the like.

The nurse call unit 14 includes a push-button switch, and detects a nurse call (also called a care call) when the switch is pressed by the subject 70. The nurse call may be detected by a voice microphone instead of the push button type switch. When the switch of the nurse call unit 14 is pressed, that is, when a nurse call is detected, the control unit 11 sends a notification (nurse call notification) indicating that there is a nurse call via the communication unit 12 and the network 50. It is transmitted to the server 20 or the like.

The voice input / output unit 15 is, for example, a speaker and a microphone, and enables voice communication by transmitting and receiving a voice signal to / from the staff terminal 40 or the like via the communication unit 12. The voice input / output unit 15 may be connected to the detection unit 10 via the communication unit 12 as an external device of the detection unit 10.

The detection unit 10 also includes a Doppler shift type body motion sensor that transmits and receives microwaves toward the bed 60 and detects Doppler shifts of microwaves caused by body movements (for example, respiratory movements) of the subject 70. May be further provided. The body movement sensor detects body movement of the chest (up and down movement of the chest) accompanying the breathing movement of the subject 70, and disorder of the cycle in the body movement of the chest and movement of the chest that is equal to or less than a preset threshold value. When the amplitude at is detected, it is recognized that there is a slight movement abnormality.

In the present embodiment, a nurse call by the nurse call unit 14 and a change in the state recognized by the detection unit 10 regarding the subject 70 are included in the staff 80 such as getting up, leaving the bed, falling, falling down, and abnormal body movement. An event for which a notification (notification) is to be performed is called an event. The detection unit 10 transmits (outputs) information on the event that has occurred and the captured image to the server 20.

(Server 20)
FIG. 4 is a block diagram showing a schematic configuration of the server. The server 20 includes a control unit 21, a communication unit 22, and a storage unit 23. The server 20 may be provided in the same building as the living room for the subject 70, or may be provided in a remote location and connectable via a network. For example, the server 20 may be a cloud server virtually constructed by a plurality of servers arranged on a network such as the Internet. The components are communicably connected to each other by a bus. The storage unit 23 functions as a database, and stores various information regarding the event list, the target person 70, and the staff 80. The control unit 21 obtains event information of a predetermined event that may lead to an accident by cooperating with the communication unit 22 and image data of a predetermined period including a time point at which an event associated with the event has occurred. Functions as a unit. Further, the control unit 21 functions as a creating unit that creates a report by analyzing the event occurrence status from the acquired data. The control unit 21 also functions as an output unit that outputs the created report in cooperation with the communication unit 22. The other control unit 21 and communication unit 22 have the same functions as those of the configuration of the detection unit 10, and thus a detailed description is omitted. As will be described later, the event list includes information on various events including a predetermined event (for example, a falling event or a falling event) that may lead to an accident. The predetermined event that may lead to the accident is also called a near-miss event, and if this situation continues, an accident may occur.

The server 20 determines (identifies) which subject 70 the event, such as a nurse call, getting up, getting out of bed, falling, falling down, etc., detected by the detecting unit 10 is related to. In this determination, the target person 70 (that is, the resident of the room) associated with the room number where the detection unit 10 that has detected the event is installed is determined. Then, the determined event type is associated with the target person 70 and added to the event list in the storage unit 23. In the present embodiment, when the subject 70 carries an IC tag, the subject 70 may be determined by reading the IC tag with an RFID reader provided in each room. . When a plurality of subjects 70 are present in one room, such as in a shared room, the subject 70 may be determined by arranging the detection unit 10 for each bed 60. In this connection, the entry of each staff 80 into the room may be detected by bringing the staff terminal 40 carried by the staff 80 close to the RFID reader.

(Fixed terminal 30)
The fixed terminal 30 is a so-called PC (Personal Computer), and includes a control unit including a CPU, a RAM, and the like, a communication unit, a display unit, an input unit, and a voice input / output unit. The fixed terminal 30 is arranged, for example, in a nurse station. Further, when outputting a report to be described later, a user (staff 80, an administrator who manages the staff 80, etc.) inputs an instruction to display a report in which the analysis result is visualized in a chart or the like on the display unit, or to display an external report. For example, a printer (not shown) outputs the data to paper. In addition, the report may include a comment input from the input unit while referring to the captured image displayed on the display unit (display) of the fixed terminal 30 as described later.

Also, the staff 80 or technical staff associates the room number with the detection unit 10 when attaching the detection unit 10 to each room (living room) through the fixed terminal 30, or associates the detection unit 10 with the room 60 such as the bed 60. The position information of the installation object, that is, the outline information of the ceiling camera 13 viewed upward is calibrated and designated. In addition, the identification information such as the name and ID number of the subject 70 who is hospitalized or resident is associated with each room number.

(Staff terminal 40)
FIG. 5 is a block diagram illustrating a schematic configuration of the staff terminal 40. The staff terminal 40 includes a control unit 41, a wireless communication unit 42, a display unit 43, an input unit 44, and an audio input / output unit 45, which are interconnected by a bus. The control unit 41 includes a CPU, a RAM, a ROM, and the like as the same configuration as the control unit 11 of the detection unit 10. The wireless communication unit 42 enables wireless communication using a standard such as Wi-Fi or Bluetooth (registered trademark), and wirelessly communicates with each device via the access point 51 or directly. The display unit 43 and the input unit 44 are touch panels, in which a touch sensor as the input unit 44 is superimposed on the display surface of the display unit 43 formed of liquid crystal or the like. The display unit 43 and the input unit 44 display various operation screens displaying a list of a plurality of events included in the event list to the staff 80, and receive various operations through the operation screen. The voice input / output unit 45 is, for example, a speaker and a microphone, and enables voice communication by the staff 80 with another staff terminal 40 via the wireless communication unit 42. The staff terminal 40 is a device that functions as a user interface of the watching system 1, and can be configured by a portable communication terminal device such as a tablet computer, a smartphone, or a mobile phone.

The staff 80 performs a login authentication process through the assigned staff terminal 40 at the start of the work. The staff 80 inputs a staff ID and a password through the touch panel (display unit 43, input unit 44) of the staff terminal 40. The staff terminal 40 transmits this to the server 20. The server 20 matches the authentication information stored in the storage unit 23 and transmits an authentication result according to the authority of the staff 80 to the staff terminal 40, thereby completing the login authentication.

(Procedure of processing of watching system)
Next, a process of accumulating event information and image data performed by the entire watching system 1 will be described with reference to FIG. FIG. 6 is a sequence chart showing the procedure of the processing of the watching system.

(Step S110)
As illustrated in FIG. 6, the detection unit 10 detects a movement of the subject 70 in the observation area or a nurse call event by the subject 70. Then, the detection unit 10 determines whether or not another event such as a fall or a fall has occurred based on the movement of the target person 70.

(Steps S120, S130)
When it is determined that an event has occurred, the event information is transmitted to the server 20. In addition, the detecting unit 10 transmits image data obtained by photographing the observation region when an event occurs. In this case, if the type of event that has occurred is a specific type, for example, an event that may lead to an accident, such as a fall or a fall, a predetermined time (for example, several seconds to several tens of seconds) before and after the occurrence time including the occurrence time A moving image may be transmitted, and for other types of events, a still image at the time of occurrence may be transmitted. As another example, the detection unit 10 continuously transmits the captured image to the server 20, and the server 20 stores the captured image in the temporary storage unit for a predetermined time (for example, the past several hours) while overwriting. . Then, when an event occurs and the event information is received from the detection unit 10, the server 20 may read out a still image or a moving image before and after the occurrence from the temporary storage unit and store the image in association with the event. .

(Step S140)
The server 20 updates the event list. FIG. 7 is an example of an event list stored in the storage unit 23. The events included in the event list include wake-up, wake-up, fall, fall, and nurse call as described above. The latest event transmitted in step S120 is added to the end of the event list.

As shown in FIG. 7, each event includes an event ID, a room number, a subject, an event type, an occurrence date and time (time), image data, and information on a corresponding state, which are automatically given as primary keys. It is. As described above, the image data is data of a still image or a moving image transmitted by step S130 and captured by the detection unit 10 when an event occurs. The response status includes a status, a response staff, and a response date and time (time). The correspondence status will be described later.

In the example shown in FIG. 7, the event with the event ID 010 is a fall, and the events with the event IDs 011 and 012 are nurse calls. The event IDs 013 to 015 are wake-up, wake-up, and fall that have occurred consecutively for one subject 70 (Mr. B). The status of the corresponding status regarding the events of the event IDs 010 to 012 has been handled, and the event IDs 013 to 015 are not supported.

(Step S150)
When the event list is updated due to a new event being detected and added, or the status of the event being changed, the server 20 updates the updated event list with all the logged-in staff terminals. Deliver to 40. Note that the distribution destination at this time may be distributed only to the staff terminal 40 used by the staff 80 in charge of the target person 70 who has caused the event. Each staff terminal 40 that has received the event list returns an acknowledgment command in response to receiving the event list from the server 20 (not shown). The server 20 may transmit the event list by transmitting only the difference data. For example, only the part that has changed from the event list transmitted immediately before, that is, only the event that has been added or updated, is transmitted to all staff terminals 40 as the event list.

(Step S160)
Each staff terminal 40 updates the display content of the display unit 43 in response to receiving the event list from the server 20.

FIG. 8 is an example of the operation screens 431 and 432 for inputting a response policy to an event displayed on the display unit 43 of the staff terminal 40. The operation screen 431 shown in the figure is a screen on which an event list is displayed in a list. Events to be displayed can be scrolled up and down by flicking.

The areas a11 and a12 of the operation screen 431 correspond to the event IDs 011 and 012 of the event list in FIG. 7, respectively. In the areas a11 and a12, an icon indicating that the call is a nurse call and that the corresponding call has been completed are displayed. The area a13 corresponds to the event IDs 013 to 015 surrounded by a broken line frame in FIG. Since these are related to the same subject 70 (Mr. B), they are displayed together in the same area. In addition, thumbnail images are displayed in the area a13 so as to be easily distinguished from corresponding areas since they are not supported. This thumbnail image is created from a still image cut out from the moving image i015 (see FIG. 7) relating to the latest event (ID015). By operating the area a14, a text message can be exchanged with another staff member 80 who is logging in. The control unit 41 makes a transition to the operation screen 432 for content confirmation by receiving a click operation on the area a13 of the staff member 80 on the operation screen 431.

(Step S170)
The staff 80 checks the contents of the event on the operation screen 432 displayed on the staff terminal 40. In the operation screen 432, in the area a21, the ID (name: B) of the target person 70 that has caused (determined) the event and the ID of the staff 80 using the staff terminal 40 (name: staff A) are displayed. ing. In the area a22, the elapsed time from the event occurrence time is displayed. As shown in the broken-line frame in FIG. 7, for the target person 70 (Mr. B), the occurrence of an event of getting up, getting out of bed, or falling over is continuously determined, and both of them are unsupported. In a22, icons representing events “wake up” and “wake up” other than the latest event are shown. Note that the elapsed time (“elapsed 0 minutes”) shown in the area a22 is the elapsed time (decimal fractions are rounded down) after the occurrence of the latest event is determined. In the area a23, a character indicating “fall” and an icon are shown. In the area a24, a thumbnail image of the captured image at the time of the fall determination is displayed. The staff 80 operates the "talk" button and the "view" button below when the thumbnail image is insufficient as information and the user wants to confirm the situation of the subject 70 who has fallen. By operating the “talk” button, a call can be made with the target person 70 (Mr. B) through the voice input / output unit 15. By operating the “view” button, the live video captured by the camera 13 can be viewed by streaming playback.

The staff 80 (staff A) decides to take charge of the fall (ID015) displayed by operating the “corresponding” button in the area a25. If not, the user returns to the event list screen by operating the return button (triangle icon) in the area a26. While one staff member 80 is displaying the operation screen 432 shown in FIG. 8 and checking the state of an event such as a fall, the prohibition process for another staff member 80 is performed under the control of the server 20. . For example, even if another staff 80 selects the same event (ID013-015) while the staff 80 is checking the status of the event of the subject 70 (Mr. B), the operation screen 431 of the other staff 80 is selected. Is displayed with the characters "Checking status", and the "Corresponding" button is not displayed or cannot be selected.

(Steps S180, S190)
The staff terminal 40 transmits a response request for the selected event to the server 20 in response to the operation of the “correspondence” button, and in response, the server 20 returns an approval notification.

(Step S200)
The server 20 updates the event list according to the processing in step S180. Specifically, the status of the event list (ID013-015: fall etc.) is changed to "corresponding". In the present embodiment, the status is changed to “corresponding” in response to the operation of the above-mentioned “corresponding” button for the event selected by the staff member 80 and displayed on the operation screen 432. In other words, by operating the "correspondence" button, a "corresponding" response status, which is information indicating that confirmation has been performed, is input, and the response date and time is recorded assuming that a response has been made. More specifically, in the event list of FIG. 7, the time at which the processes of steps S180 and S190 are performed is recorded in the corresponding date and time column. The correspondence date and time may be recorded in the response date and time column when the staff 80 enters the room of the subject 70 who has caused an event such as a fall, a fall, or a nurse call. May be completed by inputting the result of the operation on the operation screen of, and the input time may be recorded in the corresponding date and time column. In addition, in response to updating the event list, the server 20 transmits the updated event list to all the staff members 80 who have logged in.

所 定 The determination of a predetermined event that may lead to an accident for which the detection unit 10 has determined occurrence, that is, a fall or fall event, includes an erroneous determination. If the criterion for determination is strict, there is a possibility that the determination may be missed when a fall or a fall actually occurs. On the other hand, if the criterion for determination is too loose, erroneous determination such as determining the occurrence of a fall or fall event is likely to occur when no fall or fall has actually occurred.

(4) In the present embodiment, the criterion is not strict so as to minimize omission in the determination, and therefore, erroneous determination is included to some extent. The staff 80 determines whether the erroneous determination has actually occurred or not by using the staff terminal 40 to check the situation. Specifically, the staff 80 can confirm that the situation of the target person 70 is not required to actually go to the room in the case of an erroneous determination by confirming the situation of the target person 70 by using a call or a captured image. Also, even if a fall or a fall actually occurs, no injury occurs, and there is a case where no special action is required. In this case, by confirming that the call is safe with the subject 70, etc., It is not necessary to go to the living room.

In the present specification, if the detection unit 10 determines that an event such as a fall, a fall, or the like has occurred, the event is counted as the number of occurrences even if a fall, a fall, or the like has not actually occurred. In other words, the number of occurrences can be said to be the number of suspected occurrences of falls, falls, and the like.

(4) When the occurrence of an event such as a fall or a fall is determined as described above, event information including the corresponding status of the event is accumulated in the event list. Next, a process of analyzing the event occurrence status and response status using the accumulated event list, creating a report in which the analysis result is visualized, and outputting the report will be described.

(Report output processing)
FIG. 9 is a flowchart illustrating a procedure of a report output process performed by the watching system 1 according to the first embodiment. 9 is mainly performed by the control unit 21 of the server 20 executing a program stored in the storage unit 23.

(Step S310)
The control unit 21 of the server 20 accumulates (adds) event information of the event whose occurrence has been determined to the event list of the storage unit 23. Further, image data (still image or moving image) at the time when the event occurs is stored in association with the event. This accumulation process is performed by the above-described process (FIG. 6).

(Step S320)
The control unit 21 acquires, from the storage unit 23, event information of a fall or a fall that may lead to an accident. This is started, for example, by a request from a user (staff 80, an administrator who manages the staff 80, etc.) through the fixed terminal 30. The user selects a specific target person 70 through the fixed terminal 30. The control unit 21 acquires the fall / fall event information on the designated target person 70. An event of leaving the bed may be included as an event leading to another accident. For example, a change in the arrangement of furniture in the living room such as the bed 60 and the television may change the posture of the target person 70 in the bed 60 at bedtime. As a result, a part of the body such as the leg often protrudes from the bed 60, and a large number of leaving events may be determined. In such an event, leaving the bed causes a fall from the bed, which indirectly leads to an accident.

(Step S330)
The control unit 21 analyzes the number of falls and falls from the acquired event information. FIG. 10 is a diagram illustrating an example in which the analysis result of a fall / fall in a certain subject 70 (for example, Mr. B) is visualized. This figure is a table showing the transition of the total number of falls and the number of occurrences of the falls (the number of occurrences) for each hour from one day (6:00 to 5:00 (29:00) on the following day). In the table, the time zone in which one or more falls or a fall event has occurred is shown in gray.

(Step S340)
The control unit 21 determines whether the number of occurrences of a fall or a fall event per unit period has increased. This determination may be made on an hourly basis or on a daily basis. When the determination is made on a daily basis, when the number of occurrences on a certain day is equal to or more than a predetermined multiple of the average number of occurrences on the day before or on the days before the day, it can be determined that there is an increase. In the example shown in FIG. 10, the number of occurrences on October 21 is 17 times more than the average of the number of occurrences on the previous two days (20th and 19th) by 6.5 or more. It can be determined that the number of occurrences has increased on March 21. If there is an increase, the process proceeds to step S350. On the other hand, if there is no increase, the process proceeds to step S360.

(Step S350)
The control unit 21 acquires image data associated with events before and after the increase time, and displays an image based on the image data on a display of the fixed terminal 30 used by a user (staff 80, manager, etc.). indicate. The displayed image is a moving image (for example, several seconds to several tens of seconds), but may be a still image cut out from the moving image.

At this time, the information of the subject 70 stored in the storage unit 23 may be displayed on the display. The information on the target person 70 includes, for example, walking state information (independence, wheelchair, walker) of the target person 70. When displaying the images before and after, the control unit 21 analyzes the images to recognize furniture and the like (bed, walker, cane) in the living room, and arranges the furniture and the like in the two images before and after. If there is a change, an annotation image (encircling frame, notice, etc.) indicating the change may be added to the display image.

(Step S360)
The control unit 21 receives a comment to be added to the report. For example, a comment from a user is received through the fixed terminal 30.

The user compares the two images before and after the increase time displayed on the display of the fixed terminal 30 and inputs the obtained judgment result as a comment. For example, in the image after the time when the number of occurrences of the falling and falling events has increased compared to the previous image by comparing the images, if the arrangement of the furniture or the like in the living room is changed, the furniture or the like is used. It can be estimated that the number of occurrences has increased due to the change in the arrangement of. The furniture and the like include not only fixed furniture such as a bed, a television, and a chest, but also a walking tool such as a walker, a wheelchair, and a cane. For example, the number of occurrences of the event may be increased by changing the position where the wand is placed to a position different from the previous position.

Also, information on the subject 70, for example, walking state information (independence, wheelchair, walker) of the subject 70, and the walking state (photographed image) when actually alone may be compared. More specifically, the actual walking state is determined from an image taken when a person falls down and falls down alone in the living room. If this is different from the walking state information and it is found that the target person 70 is performing dangerous walking that should not be performed, this can be cited as the reason for an increase in the number of falling events. As an example of this dangerous traveling, there is a case where the target person 70 who uses a walker walks independently in a living room along a wall without using a walker.

(Step S370)
The control unit 21 creates a report based on the analysis result. If a comment is received in step S360, the comment is added to the report.

(Step S380)
The control unit 21 outputs a report by displaying it on the display of the fixed terminal 30, printing it on paper from a printer, or transmitting report data to a transmission destination address according to a request.

FIG. 11 is a diagram illustrating an example of a report that outputs a visualized analysis result. FIG. 11 reflects a result of the analysis shown in FIG. 10 and shows a report on a predetermined event that may lead to an accident regarding the target person 70 (Mr. B) selected by the user. The table in the upper part of FIG. 11 corresponds to the diagram shown in FIG. The two middle images are captured images of the living room before and after the time when the increase occurred. The comment at the bottom is the one received in step S360.

As described above, in the first embodiment, the event information of a predetermined event that may lead to an accident and the image data associated with the event information are obtained, and the number of occurrences of the event, the occurrence time , And the image data is used to analyze the event occurrence status, thereby creating a report in which the event occurrence status is visualized based on the analysis result, and outputting this.

As a result, it is possible to analyze the images of the number of falls and falls and the falls and falls detected from the daily actions of the resident (target person 70) and output a report summarizing the results of taking out the near miss. To prevent the occurrence of an event that may lead to

At the facility, it is not possible to grasp what the subject 70 is doing in the living room. That is, when the entrance door is closed, the staff 80 cannot recognize the state of the room. For this reason, it is not known that there is a dangerous behavior of the resident (such as walking that may lead to a fall), so that measures must be taken after an accident occurs.

On the other hand, according to the present embodiment, the fall / fall event detected by the detection unit 10 is analyzed, so that the resident (target person 70) of the resident (target person 70) whose facility staff 80 has not been able to grasp it. We can know dangerous behavior. Further, by encouraging countermeasures (replacement of furniture and the like) to reduce dangerous behavior, a fall or a fall can be caused, and an accident due to these can be prevented.

(Output processing of a report in the watching system 1 according to the modified example)
In the embodiment shown in FIG. 10, an input of a comment from a user is received. On the other hand, in a modified example described below, a comment is automatically created on the control unit 21 side. FIG. 12 is a flowchart illustrating a report output process according to the modification.

(Steps S410 to S440)
Here, the control unit 21 performs the same processing as steps S310 to S340 shown in FIG. If there is an increase in the number of events that have occurred, the process proceeds to step S465.

(Step S465)
The control unit 21 creates a comment that calls attention to the increase. This comment uses a fixed phrase, and creates a comment for confirming whether or not a change has been made in the period before and after the increase in the arrangement of furniture in the living room, which has led to a fall or an increase in the fall. For example, the comment column of the report in FIG. 11 is a comment that calls attention to an increase assumed in such a case. Some or all of the comments may be stored in the storage unit 23 in advance.

As described above, by creating a comment on the control unit 21 side, the same effect as that of the first embodiment can be obtained, and a report can be created without the user having to perform the trouble of creating a comment.
