Also, the dimensional ratios in the drawings are exaggerated for convenience of explanation, and may differ from the actual ratios.

FIG. 1 is a diagram illustrating the overall configuration of a monitoring system 1 (information processing system) according to an embodiment, and FIG. 2 is a schematic diagram illustrating detection units installed around a bed in a living room of a care recipient. .

As shown in FIG. 1, the watching system 1 includes a plurality of detection units 10, a management server 20, an information manager terminal 30, and one or more staff terminals 40. FIG. These are connected by wire or wirelessly so as to be able to communicate with each other via a network 50 such as a LAN (Local Area Network), a telephone network, or a data communication network. Network 50 may include repeaters, such as repeaters, bridges, routers, or cross-connects that relay communication signals. In the example shown in FIG. 1, the detection unit 10, the management server 20, the information manager terminal 30, and the staff terminal 40 are connected to each other via a network such as a wireless LAN (for example, a LAN conforming to the IEEE802.11 standard) including an access point 51. 50 are communicatively connected.

The watching system 1 is arranged at an appropriate place according to the person to be cared 70 . The care recipient 70 is, for example, a patient who needs nursing care due to illness or injury, a cared person who needs care due to a decline in physical ability due to old age, a solitary person living alone, or the like. In particular, from the viewpoint of enabling early detection and early treatment, the person to be cared for 70 can be a person who needs detection when a predetermined inconvenient event such as an abnormal condition occurs to the person. Therefore, the watching system 1 is preferably installed in buildings such as hospitals, welfare facilities for the elderly, and dwelling units according to the type of the person to be cared for 70 . In the example shown in FIG. 1, the monitoring system 1 is placed in a facility that includes a plurality of rooms (residential rooms) in which a plurality of care recipients 70 reside and a plurality of rooms including a care station.

The detection unit 10 is arranged in each living room, which is the observation area of the care recipient 70 . In the example shown in FIG. 1, four detection units 10 are arranged in the living rooms of persons A, B, C, and D who are care recipients 70, respectively. As shown in FIG. 2, the observation area of the detector 10 includes a bed 60 . A care staff member (staff) 80 who provides nursing or nursing care to a person to be cared for 70 carries a staff terminal 40, which is a portable terminal, with them. However, the position, the number, and the like of each component included in the watching system 1 are not limited to the example shown in FIG. 1 . For example, management server 20 may not be located at the care station, but may be an external server unit connected to network 50 .

In addition, the care broadly includes care provided by the care staff 80 to the care subject 70, for example, living assistance such as eating, water intake, excretion, bathing, cleaning, and vital checks (body temperature, blood pressure, pulse, etc.). measurement).

(Detector 10)
FIG. 3 is a block diagram showing a schematic configuration of the detector. As shown in the figure, the detection unit 10 includes a control unit 11, a communication unit 12, a camera 13, a care call unit 14, an audio input/output unit 15 and a pause switch 16, which are interconnected by a bus. It is Here, the detection section 10 corresponds to one specific example of the first detection section and the second detection section of the present invention.

The control unit 11 includes a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), and other memories, 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 a HDD (Hard Disk Drive) or an SSD (Solid State Drive) as memory.

The communication unit 12 is an interface circuit (such as a LAN card) for communicating with other devices such as the management server 20, the information manager terminal 30, or the staff terminal 40 via the network 50. FIG.

The camera 13 is arranged, for example, on the ceiling or the upper part of the wall of the living room, photographs the bed 60 of the care recipient 70 directly below as an observation area, and outputs a photographed image (image data). The captured images include still images and moving images. Although the camera 13 is a near-infrared camera, a visible light camera may be used in place of this, or these may be used in combination.

The control unit 11 recognizes the behavior of the care recipient 70 from the captured image captured by the camera 13 . This recognized behavior includes the lying state of the care recipient 70 . The waking state of the care subject 70 includes, for example, a “lying state” of sleeping in the bed 60, a “waking state” of getting up from the bed 60, a “awake state” before the waking state, and a “getting out of bed state” of leaving the bed 60. etc. are included. Actions recognized by the control unit 11 further include "falling" of falling on the floor or the like, "falling" of falling from the bed 60 or a wheelchair, and "exiting" of leaving the living room.

The control unit 11 detects image silhouettes (hereinafter referred to as “person 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. Recognition of getting up, leaving the bed, and falling is performed based on the posture of the care recipient 70 (for example, standing, sitting, lying down, etc.) from the detected human silhouette, and from the position relative to the bed 60 or other installations in the living room. Recognize the difference between leaving the bed and falling (falling). These recognitions 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.

The lying state of the care recipient 70 may be determined using a sensor other than the camera 13, or may be determined using this sensor and the camera 13 together. For example, the sensors include a body motion sensor, a sheet-like piezoelectric sensor placed on (or inside) the mat of the bed 60, and a vibration detection sensor placed on the bed 60, and the like. A smartphone equipped with an acceleration sensor or a gyro sensor may be used as the vibration detection sensor. Alternatively, the detection unit 10 may determine the lying state as described below using only the body motion sensor without including the camera 13 .

For example, the body motion sensor is 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 care recipient 70 . When the person to be cared 70 is in bed, a small and slight movement is observed. For this reason, in detecting the lying state using this body motion sensor, for example, two large and small thresholds regarding the magnitude of movement are set, and when the first threshold on the larger side is exceeded, the "wakeful state" is detected. or "awake state", if it is below the second smaller threshold, it is "getting out of bed", and if it is below the first threshold and above the second threshold, it is "lying down". This body motion sensor can also be used for abnormality detection. For example, the chest body movement (up and down movement of the chest) associated with the respiratory action of the care subject 70 is detected, and the disturbance of the cycle of the chest body movement and the amplitude of the chest body movement that is equal to or less than a preset threshold value are detected. is detected, it is recognized as abnormal micromotion.

By using these body motion sensors, piezoelectric sensors, or vibration detection sensors together with the camera 13 or in place of it, the lying state (getting out of bed, lying down, awakening, rising) of the care recipient 70 can be determined.

In this embodiment, the change in the state recognized by the detection unit 10 regarding the care recipient 70, such as getting up, leaving the bed, falling, falling, leaving the room, and abnormal micromovement, is notified to the care staff 80. An event that should be (notified) is called an event. This event also includes a care call by the care call unit 14 . That is, the detection unit 10 may detect a care call by the care recipient 70 as the movement of the care recipient 70 in the observation area. The detection unit 10 transmits information about the event that has occurred to the management server 20 .

Here, when the work of the care staff 80 is nursing care work for the person to be cared for 70, the content of correspondence regarding each event will be described. If the detection unit 10 determines “wake-up” as an event, and the determination is within a predetermined time (the wake-up time set in the facility (for example, 7 to 8 am)), the care staff 80 tells the care recipient 70 Perform morning care (wake-up assistance). This morning care includes face washing, tooth brushing assistance, denture wearing, dressing assistance, and the like. In addition, if it is an event of "getting out of bed", wheelchair transfer and walking assistance may be required. Regular (regular) events other than the events determined by the detection unit 10 include beverages, meal assistance, excretion assistance, wheelchair transfer, walking assistance, and position change (bedsore prevention). For these periodic events, the care call unit 14 or the like may generate an alert at the scheduled time.

The care call unit 14 includes a push-button switch, and detects a care call (nurse call) when the care recipient 70 pushes the switch. A voice microphone may be used to detect a care call instead of the push-button switch. When the switch of the care call unit 14 is pressed, that is, when a care call is detected, the control unit 11 transmits a notification of the care call to the management server 20 or the like via the communication unit 12 and the network 50 .

The voice input/output unit 15 is, for example, a speaker and a microphone, and enables voice communication by transmitting and receiving voice signals to and from the information manager terminal 30 via the communication unit 12 . Note that 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 pause switch 16 is arranged, for example, near the doorway of the living room. The temporary stop switch 16 includes, for example, a push button type switch, and when the care staff 80 or the like enters the living room, this switch is operated to temporarily stop the determination of the event by the detection unit 10. be. The determination of the event by the detection unit 10 is restarted, for example, when the pause switch 16 is operated again. The determination of the event by the detection unit 10 may be automatically restarted after a predetermined period of time has elapsed.

For the pause switch 16, an NFC (near field communication) type sensor such as FeliCa (registered trademark) may be used in place of the push button type switch or in addition to the push button type switch. The temporary stop switch 16 is turned ON/OFF by, for example, holding an IC card possessed by the care staff 80 over a reading terminal arranged at the doorway of the living room.

Therefore, it is possible to obtain information that associates the timing of changes in the lying state of individual care recipients 70 with the timing of actions of care staff 80 . As a result, the facility can grasp the relationship between the timing of the change in the lying state of the care recipient 70 and the timing of the behavior of the care staff 80, so that improvements can be made to provide more appropriate care. becomes possible.

For example, if the monitoring system does not output information that associates the timing of changes in the care recipient's lying state with the timing of the care staff's actions, it would be difficult to provide care that matches the timing of the care recipient's bedtime and wake-up. Become. For example, even if the person being cared for is awake due to the care staff entering the room at night, it is difficult to identify the causal relationship and formulate effective remedial measures.

On the other hand, in the watching system 1, the lying information about the lying state of the person to be cared for at each time, the action information including the predetermined action of the care staff 80 and the time of this action are associated and output. be done. Therefore, the facility manager or the like can easily grasp the relationship between the timing of the change in the lying state of the care recipient 70 and the timing of the behavior of the care staff 80, and can improve the care for more appropriate care. It is possible to take measures. For example, based on the information output from the monitoring system 1, the facility manager or the like can identify the awakening (or awakening) of the care recipient 70 due to the entry of the care staff 80 at night. By analyzing such awakening cases, for example, it is possible to ascertain trends in the time period in which the care subject 70 is likely to be awakened, the care staff 80, and the like. Therefore, it is possible to make effective improvement measures for performing more appropriate care in accordance with changes in the lying state of the person to be cared 70 .

As described above, according to the monitoring system 1 (management server 20) of the present embodiment, the lying information about the lying state of the care recipient 70 at each time, the predetermined behavior of the care staff 80, and the behavior It is output in association with action information including information about time. Therefore, it is possible to output information that associates the timing of changes in the lying state of individual care recipients 70 with the timing of actions of care staff 80 .

<Modification>
In the above embodiment, an example in which the control unit 21 functions as the first acquisition unit 211, the second acquisition unit 212, and the output unit 213 has been described. good. In the modification below, an example in which the control unit 21 further functions as an analysis unit (analysis unit 214 in FIG. 12 described later) will be described.

FIG. 12 is a block diagram showing an example of functions of the control section 21 according to the modification of the above embodiment. The control unit 21 of this modification functions as a first acquisition unit 211, a second acquisition unit 212, an analysis unit 214, and an output unit 213, for example, when the CPU executes an information processing program. The first acquisition unit 211 and the second acquisition unit 212 function in the same manner as described in the above embodiment.

Based on the lying information acquired by the first acquiring unit 211 and the behavior information acquired by the second acquiring unit 212, the analyzing unit 214 determines the predetermined behavior of the care staff 80 and the lying of the care recipient 70. Analyze relationships with state changes. For example, the analysis unit 214 analyzes the relationship between the entry of the care subject 70 by the care staff 80 into the room of the care subject 70 and the change of the care subject 70 from the lying state to the awake state, and Awakening or waking up of the person to be cared 70 is specified. The analysis unit 214 analyzes the relationship between the wake-up assistance by the care staff 80 and the change of the care subject 70 from the bed state to the wake-up state, and determines whether the care subject 70 wakes up or wakes up due to the care staff 80's wake-up assistance. may be specified.

The output unit 213 outputs the analysis result analyzed by the analysis unit 214 .

FIG. 13 shows an example of the analysis result output by the output unit 213. As shown in FIG. The horizontal axis of FIG. 13 represents the time, and the vertical axis represents the number of awakenings of the care recipient 70 resulting from the entry of the care staff 80 into the room. The care staff 80 makes night patrols at 21:00, 22:00, 2:00 and 4:00. For example, the analysis unit 214 defines the time when the care subject 70 wakes up or wakes up within a predetermined time after the time when the care staff 80 enters the living room of the care subject 70 as the awakening caused by the care staff 80 entering the room. Identify. At the facility, from the result output by the output unit 213, for example, since it is possible to grasp that the care recipient 70 is likely to be awakened by the night patrol at 22:00 and 2:00, the night patrol at 22:00 and 2:00 is refrained. improvement measures can be taken.

FIG. 14 shows another example of analysis results output by the output unit 213. In FIG. In FIG. 14 , the wake-up time of natural wake-up and the wake-up time due to the wake-up assistance of the care staff 80 are represented by box plots for each care subject 70 . For example, the analysis unit 214 determines that the detection time of “wake-up” immediately before the wake-up assistance is later than the time when the care staff 80 enters the room and is within a predetermined period of time. The other cases are identified as spontaneous awakening. In the facility, for example, from FIG. 14, it can be confirmed that the care recipient G, etc. in room 311 tends to wake up earlier due to the help of the care staff 80 than the wake-up time of natural wake-up. As a result, the administrator of the facility or the like can make improvements such as delaying the wake-up time period for the person to be cared for in room 311, Mr. G, or the like. The output unit 213 may output the number of times of spontaneous wake-up and the number of times of wake-up due to the help of the care staff 80 for each care subject 70 .
