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.
  • 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.
  • 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.
  • the number of occurrences can be said to be the number of suspected occurrences of falls, falls, and the like.
  • event information including the corresponding status of the event is accumulated in the event list.
  • 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.
  • 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).
  • 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.
  • 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.
  • 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.
  • 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.
  • walking state information independence, wheelchair, walker
  • the walking state photographed image
  • 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.
  • 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.
