In response to the uploading request from the management server, the sensor box starts uploading of the video (S110). Upon reception of a video request (S310) from the mobile terminal, the management server starts transferring of the uploaded video to the mobile terminal (S230). The mobile terminal starts reproduction of the video transferred from the management server (S320).

Description

Care management methods, programs, care management equipment, and care management systems

This disclosure relates to a care management system that transmits behavior information of a care recipient and images of an area associated with the care recipient to a terminal associated with the care recipient.

Care management systems for providing care to care recipients are widespread. The care management system detects behaviors such as getting up and falling by the care recipient, and notifies the caregiver of the behaviors. As a result, the caregiver can rush to the care recipient, prevent the care recipient from falling, and enable immediate treatment for the care recipient.

Regarding a technique for detecting the behavior of a long-term care recipient, Japanese Patent Application Laid-Open No. 2001-307246 (Patent Document 1) provides a human body detection device for "enable to sufficiently deal with various behavior patterns of a monitored person". Is disclosed. Japanese Unexamined Patent Publication No. 2002-230533 (Patent Document 2) discloses an image processing device that "can accurately determine a bed entry event and a bed leaving event by using a boundary edge that is the lower edge of the outer shape of the bed." Republished Patent No. 2017-188156 (Patent Document 3) discloses a technique relating to a method of outputting a notification sound when a predetermined event related to a care recipient is detected.

Japanese Unexamined Patent Publication No. 2001-307246 JP-A-2002-230533 Republished Patent No. 2017-188156

With the development of information and communication technology in recent years, some care management systems provide images taken about the care recipient to the caregiver located away from the care recipient. In such a care management system, the caregiver can recognize the condition of the care recipient in more detail by checking the video when deciding how to deal with the care recipient. In the field of long-term care, the condition of the care recipient may require an urgent response by the caregiver, or the care recipient may not need to respond because the care recipient can be expected to respond on their own. Therefore, it is ideal that the care management system is designed so that the image of the care recipient is always provided to the caregiver so that the caregiver can always recognize the condition of the care recipient in detail.

On the other hand, it is not realistic to constantly upload the video of the care recipient to the server in the care management system because the storage capacity required by the server becomes enormous. In addition, when the care management system charges for the use of the communication line for uploading the video according to the amount of data, the regular video upload results in a large increase in the running cost of the care management system. .. Since long-term care costs are covered by the property of the socially vulnerable care recipient and / or the property of public institutions such as the state, the impact of increased costs on society is greater than in other technical fields.

Depending on the above, the care management system should be designed so that the upload of the video taken about the care recipient is limited to the case where it is needed, and it is done immediately when the caregiver needs it.

This disclosure was conceived in view of such circumstances, and its purpose is to provide a technique for starting uploading of images taken of a long-term care person at an appropriate timing.

According to certain aspects of the present disclosure, a step of acquiring the behavior information of the care recipient identified based on the detection signal of the sensor regarding the care recipient, and a step of transmitting the behavior information to the terminal associated with the caregiver. In response to the acquisition of the behavior information, the step of outputting the upload request of the image taken by the image pickup device toward the image pickup device that photographs the area associated with the long-term care person, and the transfer request of the image from the terminal. A care management method is provided that comprises a step of initiating the transfer of video to the terminal upon receipt.

The step of outputting the upload request may include outputting the upload request to the imaging device without waiting for the transfer request from the terminal.

The step of outputting the upload request may include outputting the upload request on condition that it is determined that the video needs to be uploaded based on the attribute of the action information.

The behavioral information attribute may include the type of behavioral information.
The step of outputting the upload request may include outputting the upload request on condition that it is determined that the video needs to be uploaded based on the attributes of the caregiver.

The step of outputting the upload request may include outputting the upload request on condition that it is determined that the video needs to be uploaded based on the attributes of the care recipient.

If the video transfer request is not received within a given time from the step of outputting the upload request, a step of instructing the imaging device to stop uploading the video may be further provided.

The given time may be set based on the caregiver's characteristics.
The step of acquiring the behavior information of the care recipient may include receiving a detection signal from the sensor and identifying the behavior information of the care recipient by analyzing the received detection signal. ..

The step of acquiring the behavior information of the care recipient may include receiving the behavior information of the care recipient from the sensor.

The sensor may include an imaging device.
According to other aspects of the disclosure, a program is provided that, when executed by a computer, enables the computer to implement the above care management methods.

A care management system is provided that acquires behavioral information of the identified care recipient based on the generated detection signal.

According to the present disclosure, when the behavior information of the care recipient is acquired, the image of the area associated with the care recipient is displayed without waiting for the transfer request from the terminal associated with the care recipient to the care management device. Uploading from the imaging device to the care management device can be initiated. As a result, the time from the reception of the transfer request to the start of the transfer in the care management device can be shortened. The upload request is transmitted to the image pickup device along with the transmission of the behavior information to the mobile terminal. As a result, the video is uploaded on condition that the video is expected to be transferred to the image pickup device.

[1. Care management system configuration]
FIG. 1 shows an example of the configuration of a care management system. The care management system shown in FIG. 1 manages information on each of two or more patients or residents in facilities such as hospitals and welfare facilities for the elderly. In this specification, as an example, a care management system will be described as a system for managing information of a plurality of residents (care recipients) in a welfare facility for the elderly. The facility to which the care management system is applied may be another type of facility such as a hospital. The care recipient may be changed to a patient in a hospital or the like.

The care management system includes

sensor boxes

100A, 100B ..., generates a notification as needed based on the output, and transmits the generated notification to each of the

mobile terminals

300A, 300B ... ..

When each of the

mobile terminals

300A, 300B ... Receives the notification, the information included in the notification is displayed. Each of the

staff members

850A, 850B ... rushes to the living room or the like according to the display of the mobile terminal carried by each staff member and takes necessary measures.

Each of the

sensor boxes

100A, 100B ... is equipped with

cameras

105A, 105B ... Each of the

sensor boxes

100A, 100B ... Can upload the video captured by each of the

cameras

100A, 100B ... Can download and play the uploaded video.

In the present specification, when the properties common to each of the

sensor boxes

100A, 100B ..., the

mobile terminals

300A, 300B ..., and the

staff

850A, 850B ... Are mentioned, the "sensor box 100" and "mobile" are used. The terms "terminal 300" and "staff 850" may be used.

The management server 400 may send a notification to the mobile terminal 300 carried by the administrator who manages the staff, instead of sending the notification to the mobile terminal 300 carried by the staff. The care management system may, after confirming the notification, decide whether or not the staff should respond to the notification, and if so, which staff should respond to the notification.

The mobile terminal 300 operated by the staff 850 may be a smartphone or a tablet terminal. Staff 850 does not have to bring the mobile terminal 300 when moving to the room to respond to the notification. In this sense, the mobile terminal 300 may be a stationary computer.

[2. Acquisition of information on long-term care recipients]
FIG. 2 is a diagram for explaining an example of the detection range of the sensor in the living room. In the example of FIG. 2, the sensor box 100 is installed on the ceiling CL of the living room 10.

In FIG. 2, the range AR schematically represents the detection range of the sensor in the sensor box 100. If the sensor is a Doppler sensor, the Doppler sensor detects behavior that occurs within range AR. If the sensor is a camera, the camera captures an image within range AR.

In the example of FIG. 2, the bed 30 is installed in the living room 10, and the sensor in the sensor box 100 generates an output according to the behavior of the resident 20. The resident 20 can operate the care call slave unit 500. The operation content of the care call slave unit 500 in each living room 10 may be transmitted to the sensor box 100. The living room 10 is an example of the area associated with the resident 20.

[3. Hardware configuration (equipment in the living room)]
FIG. 3 is a diagram showing an example of the hardware configuration of the equipment of each living room 10. In each living room, a sensor box 100, a care call slave unit 500, a door sensor 510, a toilet sensor 520, an odor sensor 530, and a vital sensor 540 are installed.

The sensor box 100 includes a control device 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, a communication interface 104, a camera 105, a Doppler sensor 106, a wireless communication device 107, and a storage device. It includes 120.

The control device 101 controls the sensor box 100. The control device 101 is composed of, for example, at least one integrated circuit. The integrated circuit is composed of, for example, at least one CPU (Central Processing Unit), at least one ASIC (Application Specific Integrated Circuit), at least one FPGA (Field Programmable Gate Array), or a combination thereof.

An antenna (not shown) or the like is connected to the communication interface 104. The sensor box 100 exchanges data with an external communication device via the antenna. An example of an external communication device is a management server 400.

The camera 105 is a near-infrared camera in one realization example. Near-infrared cameras include IR (Infrared) floodlights that project near-infrared light. By using a near-infrared camera, an image showing the inside of the living room 10 can be taken even at night. In another embodiment, the camera 105 is a surveillance camera that receives only visible light. In still another embodiment, a 3D sensor or a thermography camera may be used as the camera 105. The camera 105 may be integrally configured with the housing of the sensor box 100, or may be configured separately.

The Doppler sensor 106 is, for example, a microwave Doppler sensor that radiates and receives radio waves to detect the behavior (movement) of an object in the living room 10. As a result, the biological information of the resident 20 in the living room 10 can be detected. In one example, the Doppler sensor 106 radiates microwaves in the 24 GHz band toward the bed 30 in each room 10 and receives the reflected waves reflected by the resident 20. The reflected wave is Doppler-shifted by the movement of the resident 20. The Doppler sensor 106 can detect the respiratory state and heart rate of the resident 20 from the reflected wave.

The wireless communication device 107 receives signals from the care call slave unit 500, the door sensor 510, the toilet sensor 520, the odor sensor 530, and the vital sensor 540, and transmits the signals to the control device 101. For example, the care call slave unit 500 includes a care call button 501, and when the care call button 501 is operated, a signal indicating that the operation has been performed is transmitted to the wireless communication device 107. The door sensor 510, the toilet sensor 520, the odor sensor 530, and the vital sensor 540 each transmit their respective detection outputs to the wireless communication device 107.

The storage device 120 is a storage medium such as a hard disk or an external storage device, for example. The storage device 120 stores a program executed by the control device 101 and various data used for executing the program. The various data may include behavioral information of the resident 20.

If at least one of the above programs and data is a storage device accessible to the control device 101, a storage device other than the storage device 120 (for example, a storage area of the control device 101 (for example, a cache memory), ROM 102, etc.). It may be stored in the RAM 103 or an external device (for example, the management server 400).

[4. Resident's behavior information]
The above behavioral information will be described. The action information is, for example, information indicating that the resident 20 has executed a predetermined action. In one example, the predetermined actions are "wake up" indicating that the resident 20 has awakened, "get out of bed" indicating that the resident 20 has left the bedding, and "fall" that indicates that the resident 20 has fallen from the bedding. , And four actions of "falling" indicating that the resident 20 has fallen.

In one embodiment, the control device 101 generates behavior information of the resident 20 associated with each living room 10 based on the image captured by the camera 105 installed in each living room 10. For example, the control device 101 detects the head of the resident 20 from the above image, and based on the time change of the size of the detected head of the resident 20, the resident 20 “gets up” and “gets out of bed”. , "Tumble" and "Tumble" are detected. Hereinafter, a specific example of generating behavioral information will be described in more detail.

First, the storage device 120 stores the location area of the bed 30 in the living room 10, the first threshold Th1, the second threshold Th2, and the third threshold Th3. The first threshold Th1 discriminates the size of the resident's head between the lying posture and the sitting posture in the location area of the bed 30. The second threshold Th2 identifies whether or not the resident is in a standing posture based on the size of the resident's head in the living room 10 excluding the area where the bed 30 is located. The third threshold value Th3 identifies whether or not the resident is in a lying position based on the size of the resident's head in the living room RM excluding the area where the bed 30 is located.

The control device 101 extracts a moving object area from the target image as an area of a person of the resident 20 by, for example, a background subtraction method or a frame subtraction method. The control device 101 is further derived from the extracted moving body region by a neural network learned for head detection by pattern matching using a head model prepared in advance by, for example, a circular or elliptical Hough transform. The head area of the resident 20 is extracted using the set threshold. The control device 101 detects "getting up", "getting out of bed", "falling", and "falling" from the position and size of the extracted head.

In the control device 101, the position of the head extracted as described above is within the location area of the bed 30, and the size of the head extracted as described above is laid down by using the first threshold Th1. It may be determined that the action "wake up" has occurred when it is detected that the size of the posture has changed to the size of the sitting posture.

The control device 101 is a case where the position of the head extracted as described above moves from the inside of the location area of the bed 30 to the outside of the location area of the bed 30, and the size of the head extracted as described above. May determine that the behavior "getting out of bed" has occurred when it detects that the size has changed from a certain size to the size of a standing posture by using the second threshold Th2.

The control device 101 is a case where the position of the head extracted as described above moves from the inside of the location area of the bed 30 to the outside of the location area of the bed 30, and the size of the head extracted as described above. When the time changes from a certain size to the size of the lying posture by using the third threshold Th3, it may be determined that the behavior "fall" has occurred.

In the control device 101, the position of the head extracted as described above is located in the living room 10 excluding the area where the bed 30 is located, and the size of the extracted head uses the third threshold Th3. When it is detected that the size has changed from a certain size to the size of the lying posture, it may be determined that the behavior "fall" has occurred.

As described above, in one specific example, the control device 101 of the sensor box 100 generates the behavior information of the resident 20. In the care management system, the behavior information of the resident 20 may be generated by other elements using the image in the living room 10. In the sensor box 100, the camera 105 is an example of an “imaging device”. The Doppler sensor 106 in the sensor box 100 is an example of a “sensor”, and various sensors such as a vital sensor connected to the sensor box 100 are another example of a “sensor”. The sensor box 100 transmits behavior information to the management server 400. The management server 400 is an example of a “care management device”.

In another specific example, the sensor box 100 may transmit detection signals of various sensors to the management server 400, and the management server 400 may generate behavior information using the detection signals transmitted from the sensor box 100.

The management server 400 generates a notification using the action information from the sensor box 100 or the action information generated based on the detection signal from the sensor box 100, and transmits the generated notification to the mobile terminal 300. As a result, when the sensor box 100 detects an action such as getting up of the resident or an action (pressing) on the care call button 501, the action is notified to the mobile terminal 300. Some of the action information is generated according to the operation by the resident, such as pressing the care call button 501, while the action information is operated by the resident, such as "wake up" generated based on the detection signal of the camera 105 or the like. Some are generated without need.

[5. Hardware configuration (mobile terminal)]
FIG. 4 is a diagram showing an example of the hardware configuration of the mobile terminal 300. The mobile terminal 300 includes a control device 301, a RAM 303, a communication interface 304, a display 305, an input device 306, and a built-in memory 320.

The control device 301 controls the mobile terminal 300. The control device 301 is composed of, for example, at least one integrated circuit. An integrated circuit is composed of, for example, at least one CPU, at least one ASIC, at least one FPGA, or a combination thereof.

An antenna (not shown) or the like is connected to the communication interface 304. The mobile terminal 300 exchanges data with an external communication device via the antenna and the access point. The external communication device is, for example, the sensor box 100.

The display 305 is realized by, for example, an organic EL (Electro Luminescence) display. The input device 306 is realized, for example, by a touch sensor superimposed on the display 305. The touch sensor receives various operations on the mobile terminal 300 by touch operations, and outputs the contents of the operations to the control device 301.

The built-in memory 320 is, for example, a storage medium such as an eMMC (Embedded MultiMediaCard). As an example, the built-in memory 320 stores a program executed by the control device 301, but the program is stored in a storage device other than the built-in memory 320 if the storage device is accessible to the control device 301. May be good.

[6. Hardware configuration (management server)]
FIG. 5 is a diagram showing an example of the hardware configuration of the management server 400. The management server 400 includes a control device 401, a ROM 402, a RAM 403, a communication interface 404, and a storage device 420.

The control device 401 controls the management server 400. The control device 401 is composed of, for example, at least one integrated circuit. An integrated circuit is composed of, for example, at least one CPU, at least one ASIC, at least one FPGA, or a combination thereof.

An antenna (not shown) or the like is connected to the communication interface 404. The management server 400 exchanges data with an external communication device via the antenna. External communication equipment includes, for example, a sensor box 100.

The storage device 420 is a storage medium such as a hard disk or an external storage device, for example. In one embodiment, the storage device 420 stores a program executed by the control device 401, which may be stored in another storage device accessible to the control device 401. The program may be stored in a recording medium that can be attached to and detached from the management server 400 main body. The storage device 420 includes a resident information area 421, a staff information area 422, and a data area 423.

The attributes of each resident can be stored in the resident information area 421. In one realization example, the attributes of the resident are name, age, degree of care required, care record, room number (assigned to each room), and sensor box information (assigned to each sensor box). Including.

The attributes of each staff member can be stored in the staff information area 422. In one implementation, staff attributes include name, age, years of experience in long-term care, years of service at a facility to which a care management system is applied, history of resident response at the facility, and work shifts.

The data area 423 may store a program executed by the processor of the control device 401 and / or data used for processing executed by the management server 400.

[7. Notification screen]
FIG. 6 is a diagram showing an example of a notification screen displayed on the display 305 by the mobile terminal 300 in response to receiving a notification from the management server 400.

The notification screen 600 has a menu bar area 601, a resident name area 602 that displays the room number and name of the resident corresponding to the notification, and an elapsed time indicating the elapsed time from the time when the notification is sent from the management server 400. It includes an area 603 and an information area 604 for displaying information such as a type of notification. The information area 604 displays a "corresponding" button 605 and a "view video" button 606, in addition to the type of notification (icons representing "falls" and falls in FIG. 6).

The notification transmitted from the management server 400 to the mobile terminal 300 may include information (sensor box information) indicating which sensor box the action information based on the notification is based on. The room number and name displayed in the resident name area 602 may be the resident's room number and name associated with the sensor box on which the notification is based.

The mobile terminal 300 may include a timer. The time displayed in the elapsed time area 603 may be the elapsed time after receiving the notification from the management server 400 measured by the timer.

The notification transmitted from the management server 400 to the mobile terminal 300 may include the type of action information based on the notification (“wake up”, “get out of bed”, “fall”, “fall”, “care call button operation”, etc.). The type of notification displayed in the information area 604 may be the type of action information included in the notification transmitted from the management server 400.

When the mobile terminal 300 detects an operation on the "corresponding" button 605, the management server 400 may be notified that the staff 850 carrying the mobile terminal 300 responds to the notification. Upon receiving the notification, the management server 400 may instruct the mobile terminal 300 to stop displaying the notification screen corresponding to the notification. That is, in the care management system, when a certain notification is transmitted to the plurality of mobile terminals 300, the notification screen may be displayed on the plurality of mobile terminals 300. When the staff 850 inputs an intention corresponding to the notification to at least one mobile terminal 300, the display of the notification screen on the plurality of mobile terminals 300 may be terminated.

More specifically, the information area 604 of the notification screen 700 includes a frame 701 that displays an image captured by the camera 105 of the sensor box 100.

[8. sequence]
In the care management system, one of two types of sequences may be executed depending on the type of notification transmitted to the mobile terminal 300. An example of the first type of notification is a notification based on the behavioral information "wake up". For this type of notification, in one realization example, the staff can often determine the necessity and / or the content of the response to the behavior information without looking at the video of the living room. An example of the second type of notification is a notification based on the behavioral information "fall". In one realization example, for this type of notification, the staff decides whether or not the resident is ready to stand up on his own or needs the assistance of the staff by judging from the video of the room. In many cases. Two types of sequences will be described below.

(1) First Sequence FIG. 8 is a diagram showing a first sequence implemented in a care management system. In FIG. 8, the process executed by the sensor box 100 is shown on the left side, the process executed by the management server 400 is shown in the center, and the process executed by the mobile terminal 300 is shown on the right side. The processing of the sensor box 100, the management server 400, and the mobile terminal 300 may be realized by the CPU in each control device executing a given program, or may be dedicated to each control device. It may be realized by the electric circuit of.

In step S100, the sensor box 100 transmits detection signals of various sensors (Doppler sensor 106, vital sensor 540, camera 105, care call button 501, etc.) to the management server 400.

In step S200, the management server 400 receives the detection signal, generates action information using the detection signal, and generates a notification based on the action information.

In step S210, the management server 400 transmits the notification generated in step S200 to the mobile terminal 300.

In step S300, the mobile terminal 300 acquires a video request for the notification transmitted from the management server 400. More specifically, the mobile terminal 300 displays a notification screen corresponding to the notification transmitted from the management server 400, and detects an operation on the "view video" button 606 of the notification screen. Detection of an operation on the "view video" button 606 is an example of acquiring a video request.

In step S310, the mobile terminal 300 transmits a video request corresponding to the notification transmitted in step S210 to the management server 400. The "video request" transmitted from the mobile terminal 300 to the management server 400 means, in one implementation example, a transfer request for the video captured by the camera 105.

In response to the video request, the management server 400 transmits a video upload request for the living room to the sensor box 100 in step S220. The request in step S220 is transmitted to the sensor box in the corresponding living room with the notification transmitted in step S220.

In step S110, the sensor box 100 starts uploading the image captured by the camera 105 to the management server 400.

In step S230, the management server 400 starts transferring the video uploaded from the sensor box 100 to the mobile terminal 300.

In step S320, the mobile terminal 300 starts playing the video whose transfer was started in step S230.

(2) Second Sequence FIG. 9 is a diagram showing a second sequence implemented in the care management system. Also in FIG. 9, each process of the sensor box 100, the management server 400, and the mobile terminal 300 may be realized by the CPU in each control device executing a given program, or each of them. It may be realized by a dedicated electric circuit in the control device.

In the sequence of FIG. 9, the management server 400 sends a notification to the mobile terminal 300 in step S210, and sends an upload request to the sensor box 100 in step S220. The transmission of the upload request to the sensor box 100 in step S220 is performed in response to the generation of the action information. That is, in step S220, the management server 400 transmits the upload request to the sensor box 100 without waiting for the video request from the mobile terminal 300. The transmission of the upload request in step S220 occurs in association with the transmission of the notification in step S210. The upload request may be sent before the notification is sent, as long as the notification is decided to be sent.

"Generation" of behavior information is an example of "acquisition" of behavior information. The management server 400 may "acquire" the behavior information by receiving the behavior information from an external device such as the sensor box 100, instead of generating the behavior information on the management server 400.

The sensor box 100 starts uploading the video in step S110 in response to the upload request from the management server 400. The uploaded video is stored in the management server 400.

The management server 400 starts transferring the uploaded video to the mobile terminal 300 in step S230 in response to the reception of the video request (step S310) from the mobile terminal 300.

In step S320, the mobile terminal 300 starts playing the video transferred from the management server 400.

In FIG. 9, for comparison, the timings of steps S110, S220, and S320 in FIG. 8 are shown by broken lines. In the second sequence of FIG. 9, the management server 400 sends an upload request to the sensor box 100 at an earlier timing as compared with the first sequence of FIG. As a result, in the second sequence, the sensor box 100 starts uploading the video at an earlier timing as compared with the first sequence. As a result, the management server 400 can start transferring the video to the mobile terminal 300 in a shorter time after receiving the video request from the mobile terminal 300. Therefore, the mobile terminal 300 can start playing the video at an earlier timing.

Further, in the second sequence, since the sensor box 100 starts uploading the image at an earlier timing as compared with the first sequence, an image showing the situation at an earlier timing can be provided to the mobile terminal 300.

As described above, as described with reference to FIG. 9, the management server 400 generates (or receives) action information in step S200, and transmits a notification including the action information to the mobile terminal 300 in step S210. Then, in step S220, the upload request is transmitted to the sensor box 100, and in step S230, the transfer of the video to the mobile terminal 300 is started in response to the request from the mobile terminal 300 in step S310.

Further, as explained with reference to FIG. 8, in the care management system, one of two types of sequences can be executed depending on the type of notification. In the care management system, the sequence of FIG. 9 may be executed regardless of the type of notification. That is, regardless of the type of notification, the management server 400 uploads the video to the sensor box 100 in response to the transmission of the notification to the mobile terminal 300, regardless of whether or not the video request from the mobile terminal 300 has been acquired. You may request it.

Whether the first sequence or the second sequence is executed, that is, the management server 400 waits for the video request from the mobile terminal 300 and sends the upload request, or does not wait for the video request from the mobile terminal 300. Whether to send the upload request to the mobile terminal 300 may be determined based on the attribute of the staff possessing the mobile terminal 300 to which the management server 400 has sent the notification.

For example, the correspondence history stored in the staff information area 422 may include information indicating whether or not the staff has operated the "view video" button 606 before operating the "corresponding" button 605. .. The information is an example of staff attributes.

Operating the "view video" button 606 before operating the "corresponding" button 605 means that the staff decides to respond to the notification after viewing the video in the room. The management server 400 executes the second sequence when the staff operating at the time of transmitting the notification includes a staff who has decided to respond to the notification after seeing the image of the living room. You may. The management server 400 may execute the first sequence if the staff running at the time of sending the notification does not include such staff.

Another example of staff attributes is the length of service of staff. Management Server 400 executes a second sequence if all of the staff members in operation at the time of sending the notification have been in service for less than a given number of years, and if it is greater than or equal to a given number of years. The first sequence may be executed. This allows a second sequence to be performed if the staff has a relatively short service period and is likely to see a video of the room to determine if a response is required, which is unlikely. In some cases, the first sequence may be performed.

Whether the first sequence or the second sequence is executed may be determined based on the attributes of the resident corresponding to the notification sent from the management server 400 to the mobile terminal 300.

An example of the attributes of a resident is the degree of long-term care required. The management server 400 executes the first sequence when the resident's degree of care required corresponding to the notification is relatively high (for example, the degree of care required 4 or higher), and when it is relatively low (for example, the degree of care required 3). The second sequence may be executed in (below). As a result, the staff is likely to decide to respond to notifications from residents with a high degree of nursing care without checking the video of the room, and to notify notifications from residents with a low degree of nursing care in the room. If there is a high possibility that the necessity of the response will be decided after confirming the video of, the video upload can be started efficiently.

Whether the first sequence or the second sequence is executed may be determined based on the attributes of the behavior information.

An example of the attribute of behavior information is the time when the behavior caused by the behavior information occurs. In the data area 423, information that specifies a time zone in which congestion of the communication line connecting the elements in the care management system (sensor box 100-management server 400, management server 400-mobile terminal 300) is predicted (hereinafter, , Also called "congestion information") is stored. The management server 400 executes the second sequence when the time when the action occurs is included in the time zone specified by the congestion information, and when the above time is not included in the time zone specified by the congestion information. May execute the first sequence.

Whether the first sequence or the second sequence is executed may be determined according to the conditions derived by machine learning using various data. For example, if a correlation is obtained between the type of behavior information and the information indicating whether or not the staff watched the video before deciding the response by machine learning using the past response history, etc., it is managed. The server 400 may use the correlation to determine whether to execute the first sequence or the second sequence. More specifically, machine learning gives us the insight (correlation) that "in the case of behavioral information'fall', the staff has a 90% chance of deciding whether or not to respond without seeing the video." If so, the management server 400 may execute the first sequence if the action information related to the notification is "fall". If the machine learning gives the insight that "in the case of behavior information" care call button operation ", the staff has an 85% probability of deciding whether or not to respond after watching the video", the management server 400 May execute the second sequence if the action information related to the notification is "care call button operation".

In the examples of FIGS. 8 and 9, the management server 400 uses the detection signal from the sensor box 100 to generate action information, but the sensor box 100 generates the action information and replaces the detection signal or the detection signal. You may also send the action information to the management server 400.

[9. Specific example of timing]
FIG. 10 is a diagram for explaining a specific example of the difference in the timing of starting video reproduction in the mobile terminal 300 between the first sequence and the second sequence. In the example of FIG. 10, as a result of the processing power related to communication between the sensor box 100, the mobile terminal 300, and the management server 400, a delay may occur from the start of video upload to the start of transfer. More specifically, in the example of FIG. 10, there may be a delay of about 5 seconds from the start of uploading by the sensor box 100 to the start of transfer by the management server 400, and the start of transfer by the management server 400 to the start of playback by the sensor box 100. There can be a delay of about 5 seconds before the start.

FIG. 10 will be described from the second sequence. In the second sequence, when the notification is generated at 12:00:00 (time “12:00:00” in FIG. 10), the management server 400 sends the notification to the mobile terminal 300 at that time. At the same time, a video upload request is transmitted to the sensor box 100. The sensor box 100 starts uploading the video to the management server 400 when the upload request is received.

In the example of FIG. 10, in the mobile terminal 300, the staff operates the "view video" button 606 10 seconds after receiving the notification. As a result, at 12:00:10, the mobile terminal 300 transmits a video request to the management server 400. When the management server 400 receives the video request, the management server 400 starts transferring the video uploaded from the sensor box 100.

The mobile terminal 300 can start playing back the video 5 seconds after the start of the transfer from the management server 400, that is, at 12:00:15.

On the other hand, in the first sequence, the management server 400 sends a notification to the mobile terminal 300 at 12:00:00 and then waits for a video request from the mobile terminal 300.

When the management server 400 receives the video request from the mobile terminal 300 at 12:00:10, the management server 400 sends an upload request to the sensor box 100. In response to the reception of the upload request to the sensor box 100, the video upload to the management server 400 is started.

The management server 400 can transfer the video to the mobile terminal 300 5 seconds after the start of uploading the video by the sensor box 100, that is, at 12:00:15.

The mobile terminal 300 can reproduce the video 5 seconds after the start of video transfer by the management server 400, that is, at 12:00:20.

Compared with the first sequence, in the second sequence, when the management server 400 receives the video request from the mobile terminal 300, the management server 400 can transfer the video already uploaded from the sensor box 100. In the second sequence, after receiving the video request, playback of the video can be started on the mobile terminal 300 without waiting for the delay time of uploading from the sensor box 100 to the management server 400. That is, in the second sequence, the reproduction of the video on the mobile terminal 300 can be started earlier by the delay time of uploading from the sensor box 100 to the management server 400.

Further, in the first sequence, the image provided to the mobile terminal 300 is the image after 12:00:10, whereas in the second sequence, the image is provided after 12:00. That is, in the second sequence, the video from the time when the notification is transmitted to the time when the video request is transmitted, which is not provided to the mobile terminal 300 in the first sequence, can be provided to the mobile terminal 300.

[10. Request to cancel upload]
FIG. 11 is a diagram showing a modified example of the second sequence of FIG. In the example of FIG. 11, the management server 400 instructs the sensor box 100 to stop uploading the video if it does not receive the video request from the mobile terminal 300 for a given time or more after sending the upload request to the sensor box 100. To do.

More specifically, if the video request is not received from the mobile terminal 300 for a given time after the upload request is transmitted to the sensor box 100 in step S220, the upload stop instruction is given to the sensor box 100 in step S222. Send. In response to this, in step S112, the sensor box 100 finishes uploading the video.

The above given time may be constant or may be set based on the attributes of the staff in operation. For example, the correspondence history stored in the staff information area 422 may include information indicating whether or not the staff has operated the "view video" button 606 before operating the "corresponding" button 605. .. The information is an example of staff attributes. If the management server 400 includes a staff member who has been operating at the time of transmitting the notification in step S200 and has decided to respond to the notification after seeing the video of the living room, such a case. The "predetermined time" may be set longer than when the staff is not included.

Another example of staff attributes is the length of service of staff. The management server 400 will provide a "predetermined amount of time" if all of the staff members in operation at the time of sending the notification have been in service for less than a given number of years, rather than more than a given number of years. It may be set longer. As a result, the management server 400 can wait for a longer time for a video request from the mobile terminal 300 to bring about a quick start of video playback by the second sequence when an inexperienced staff member is operating. ..

It should be considered that each embodiment disclosed this time is an example in all respects and is not restrictive. The scope of the present invention is shown by the claims rather than the above description, and it is intended that all modifications within the meaning and scope equivalent to the claims are included. In addition, the inventions described in the embodiments and the modifications are intended to be implemented, either alone or in combination, wherever possible.
