  2. Description of the Related Art A nurse call system that can call a medical worker in response to a call operation of a patient or the like in a facility such as a medical facility or a care facility is known.

  Also, it detects whether the bed is empty or not, and if it is empty, notifies the end of bed making according to the calling operation, and if it is not empty, makes a nurse call according to the calling operation. A nurse call system for notifying is known (for example, see Patent Document 1).

  By the way, in facilities such as medical facilities and nursing care facilities, the situation of bed user (patient etc.) getting out of bed, returning to bed, etc. using temperature image data taken by a thermo camera etc. provided around the bed. Is detected, and a user's situation is notified to a nurse call system or the like. For example, using the temperature image data, an area of the temperature and size corresponding to the user is detected, the situation of the user is estimated, and the situation of the user is notified to the nurse call system based on the estimation result. be able to. Thereby, for example, it is possible to realize a notification control system that facilitates ensuring the privacy of the bed user and detecting the situation of the user at night after the lights are turned off.

  However, according to this method, after the user leaves the bed, for example, when a medical worker visits the bed or around the bed, it is erroneously detected that the user has returned to the bed, and the nurse system is notified. In some cases.

  Further, in order to prevent such erroneous detection, for example, after an area of a temperature and a size corresponding to a person is detected around the bed, the user moves to the bed and a predetermined time has elapsed, and then the user moves to the bed. It is also conceivable that it is determined that the child returned to bed. However, such a method of taking a long time to judge the situation of the user has a problem in that the notification to the nurse call system is delayed if an accident or the like occurs to the bed user. .

  As described above, the notification control device that notifies the user of the situation of the user to the predetermined notification destination based on the temperature image data captured in the predetermined imaging range suppresses a delay of the notification indicating the status of the user and suppresses the error. Reducing notifications has been challenging.

  An embodiment of the present invention has been made in view of the above problems, and is a notification control device that notifies a user of a user's situation to a predetermined notification destination based on temperature image data captured in a predetermined imaging range. In the above, the erroneous notification is reduced while suppressing the delay of the notification indicating the situation of the user.

  In order to solve the above-described problem, a notification control device according to an embodiment of the present invention is a notification control device that controls a notification based on information of a subject, and includes a temperature indicating a temperature of the subject captured in a predetermined capturing range. An information receiving unit that receives information of the subject including image data; and a notification control unit that notifies a predetermined notification destination of notification information indicating a state of the subject based on the information of the subject. The control unit stops the process of notifying the notification information to a predetermined notification destination according to whether or not the information of the subject includes predetermined identification information.

  According to the embodiment of the present invention, in a notification control device that notifies a user of a user status to a predetermined notification destination based on temperature image data captured in a predetermined image capturing range, a notification delay indicating a user status is delayed.

<System configuration>
FIG. 1 is a diagram illustrating an example of a system configuration of a notification control system according to an embodiment. The notification control system 100 communicates with a plurality of information collection devices 102a to 102f installed in an inpatient ward 110 which is an example of a facility such as a medical facility or a nursing care facility, and with a plurality of information collection devices 102a to 102f via a network 104. It includes a notification control device 101 operatively connected.

  In the following description, when an arbitrary information collection device is indicated among the plurality of information collection devices 102a to 102f, the "information collection device 102" is used. Further, the number of the information collecting apparatuses 102 illustrated in FIG. 1 is an example, and the number of the information collecting apparatuses 102 may be one or more.

  The information collection device 102 includes a thermo camera that captures temperature image data indicating the temperature of a subject, a short-range wireless module that receives identification information transmitted from a Bluetooth (registered trademark) Low Energy (hereinafter, referred to as BLE) tag, and the like. have. Note that the information collection device 102 may be called a bed monitoring camera or simply a camera.

  A thermo camera is an imaging device that images infrared radiation from an object to be measured, converts the image into temperature, and visualizes the temperature distribution with colors or the like. The thermo camera may be called a thermographic camera, thermography, thermovision, thermoviewer, or the like.

  In the example of FIG. 1, the plurality of information collecting apparatuses 102a to 102f are installed on the wall or ceiling of each of the sick rooms corresponding to each of the plurality of beds 103a to 103f provided in the sick rooms A to F. . For example, the information collection device 102a is installed on a wall surface corresponding to the bed 103a provided in the hospital room A, and captures temperature image data indicating the temperature of the bed 103a and the subject around the bed 103a (a predetermined imaging range). It is installed so that it can be.

  The information collection device 102a uses a thermo camera to photograph the bed 103a and the temperature image data around the bed 103a at a predetermined frame rate (for example, 5 fps to 1 fps).

  Further, in the present embodiment, it is assumed that a medical worker (for example, a doctor, a nurse, a caregiver, or the like) working at a facility has a BLE tag that transmits identification information for identifying the medical worker. . The information collecting apparatus 102a uses a short-range wireless module to transmit identification information (hereinafter referred to as wireless communication) transmitted from a BLE tag possessed by a medical worker (hereinafter, simply referred to as “medical worker”) working at a facility. ID).

  It should be noted that the medical staff may include various staffs working at the facility. Further, the temperature image data acquired by the thermo camera may be still image data photographed at predetermined time intervals (for example, at intervals of 10 seconds to 60 seconds). Further, the short-range wireless module may receive a wireless ID transmitted from a wireless tag other than the BLE tag, such as an active tag of an RFID (Radio Frequency Identifier), instead of the BLE tag.

  In the above configuration, the information collection device 102a transmits the user information including the captured temperature image data to the notification control device 101 via the network 104. The user information includes identification information (for example, an IP address, a device ID, and a bed ID) for specifying the information collection device 102a and the bed 103a. When the information collection device 102a receives the wireless ID, the user information includes the received wireless ID.

  Similarly, the other information collecting apparatuses 102b to 102f also transmit the user information including the corresponding bed, the temperature image data obtained by photographing the periphery of the bed, the received wireless ID, and the like via the network 104 via the notification control apparatus. Send to 101.

  The notification control device 101 is an information processing device having a configuration of a computer or a system including a plurality of information processing devices. The notification control device 101 receives the user information transmitted from the information collection device 102 and, based on the received user information, transmits notification information indicating the state of the user using the bed, for example, a nurse call A predetermined notification destination such as the system 121 is notified.

  For example, the notification control device 101 detects a temperature change of a predetermined pattern in one or more detection regions set in advance in the imaging range using the temperature image data included in the user information. Further, when a temperature change of a predetermined pattern is detected, the notification control device 101 sends a notification including notification contents (for example, information indicating a user state, temperature image data, and the like) corresponding to the detected temperature change. The information is notified to the nurse call system 121.

  In addition, the notification control device 101 according to the present embodiment stops the process of notifying the notification information to the nurse call system 121 according to whether or not the user information includes a predetermined wireless ID. Has a function.

  For example, the notification control device 101 uses the temperature image data included in the user information to detect that the user of the bed 103 has left the bed, and then returns when the user returns to the bed 103. Is returned to a predetermined notification destination. However, with the temperature image data, it is difficult to determine whether the returned person is a bed user or a medical worker.

  Therefore, as an example, the notification control device 101 may determine whether the received user information includes a pre-registered wireless ID of a medical worker or a facility staff, or a person from outside the facility (for example, cleaning). When the wireless ID of a contracted entrepreneur such as a member is included, it is determined that the returned person is a medical worker or the like, and the notification information is notified to the nurse call system 121. Cancel the processing to be performed. With this processing, the nurse call system 121 is erroneously used, for example, when a bed user gets back on a wheelchair with the staff of the facility or when a medical worker or the like makes a bed. Can be reduced.

  As another example, when the received user information does not include the wireless ID of the bed user, the notification control device 101 determines that the returning person is not the bed user, The process of notifying the nurse call system 121 of the information may be stopped.

  As yet another example, a BLE tag is attached to a tray or a container used by a user for a meal or the like, and even if a user is detected in a predetermined area on a bed described later, the received user information is not included. If the wireless ID of the BLE tag is included, the process of notifying the notification information to the nurse call system 121 may be stopped.

  Here, the notification control device 101 transmits the notification information to a nurse call system when the user information includes a wireless ID of a medical worker, a facility staff, or a person from outside the facility, which is registered in advance. The following description will be made assuming that the process of notifying 121 is stopped. The wireless ID of a medical worker, a staff of a facility, a person from outside the facility, a wireless ID of a bed user, and the like registered in advance are examples of predetermined identification information.

  The nurse call system 121 is an information processing device having a computer configuration or a system including a plurality of information processing devices, and is an example of a predetermined notification destination to which the notification control device 101 notifies notification information. The nurse call system 121 displays call information by a user (for example, a patient, a care recipient, etc.) using the bed 103, display devices 122a to 122c installed in nurse stations A to C, a nurse, a caregiver, and the like. Is displayed on the information terminal 123 or the like owned by the staff member.

  The nurse call system 121 according to the present embodiment is connected to the notification control device 101 via the network 104 and receives notification information notified from the notification control device 101, as shown in FIG. Further, the nurse call system 121 can cause the display devices 122a to 122c, the information terminal 123, and the like to display a display screen for notifying the status of the user based on the received notification information.

  The plurality of display devices 122a to 122c are display devices provided in a nurse station or the like, and display a display screen transmitted from the nurse call system 121.

  The information terminal 123 is an information terminal such as a smartphone, a tablet terminal, and a notebook PC possessed by staff members such as nurses and caregivers. The information terminal 123 can communicate with the nurse call system 121 by wireless communication, for example, and can display a display screen transmitted from the nurse call system 121 by executing a predetermined application.

(Example of arrangement of bed and camera)
FIG. 2 is a diagram illustrating an example of an arrangement of a bed and a camera according to an embodiment. This embodiment can be applied to a case where a plurality of beds 103 are provided in one sickroom 111 as shown in FIGS. 2A and 2B, for example.

  For example, as shown in FIG. 2A, the information collecting device 102 is mounted on a wall of a hospital room 111 or the like so as to acquire a bed 103 corresponding to the information collecting device 102 and image data around the bed. is set up. The information collection device 102 may be installed on the ceiling of the hospital room 111.

  FIG. 2B shows a state where the hospital room 111 is viewed from above. The information collection device 102 is installed so as to be able to use a thermo camera to capture temperature image data of a bed 103 corresponding to the information collection device 102 and a predetermined imaging range 201 including the periphery of the bed 103. .

  Further, the information collecting apparatus 102 receives the radio wave transmitted by the BLE tag in the communication range 202 including the bed 103 and the periphery of the bed 103 using the short-range wireless module, and acquires the wireless ID included in the radio wave. It is tuned so that you can.

  Each medical worker has a BLE tag for transmitting a wireless ID for identifying the medical worker. The BLE tag can control the communication distance based on the strength of the radio wave to be transmitted. For example, the intensity of the radio wave to be transmitted is set so that the communication distance is about 3 m to 4 m.

(Example of detection area)
FIG. 3 is a diagram illustrating an example of a detection area according to an embodiment. The notification control device 101 manages one or more detection areas set in advance within the imaging range 201 of the information collection device 102.

  For example, as shown in FIG. 3A, a detection frame 301 including a plurality of small regions 302 is set in the imaging range 201 of the information collection device 102. In the example of FIG. 3A, 25 small areas 302 identified by columns A to E and rows 1 to 5 are provided in the detection frame 301.

  As shown in FIG. 3B, the notification control device 101 manages area information 310 in which 25 small areas 302 are stored in association with a plurality of detection areas. For example, in the example of FIG. 3B, the attention area B is represented by “C3” indicating the position of the small area. The attention area C is represented by “B2, C2” and “B4, C4” indicating the positions of the plurality of small areas. Thereby, the notification control device 101 can easily manage a change in temperature in one or more detection areas.

(Example of detection pattern)
FIG. 4 is a diagram illustrating an example of a detection pattern according to the embodiment. The notification control device 101 detects a temperature change of a predetermined pattern in one or more detection regions set in the imaging range 201 using the temperature image data included in the user information received from the information collection device 102. I do.

  As a preferred example, the notification control device 101 detects the position of the user 401 using the bed 103 based on the temperature of the head 402 of the user 401. The head 402 of the body of the user 401 is less likely to be covered with, for example, clothes or blankets, and the face is hardly affected by hair, so that it is suitable for detecting the position of the user 401. It is.

  For example, in the temperature image data included in the user information, as shown in FIG. 4A, the head 402 of the user 401 has a temperature different from other portions (a color different from other portions). It is represented by Accordingly, the notification control device 101 detects an area at a predetermined temperature (for example, 30 ° C. to 40 ° C.) and corresponding to the size of the head 402 from the temperature image data. The position can be detected.

  In the example of FIG. 4A, an example of a detection pattern when the head 402 of the user 401 moves to the attention area A410 defined in FIGS. 3A and 3B is an example of the detection pattern. Is shown. When the head 402 of the user 401 moves to the attention area A410, the notification control device 101 determines that, for example, there is a risk that the user 401 falls from the bed 103. In this case, the notification control device 101 notifies a predetermined notification destination such as the nurse call system 121 of notification information indicating that there is a risk that the user 401 falls from the bed. The notification information includes falling attention information indicating that the user 401 may fall from the bed 103, a bed ID for identifying the bed 103, temperature image data determined to be dangerous, current temperature image data, and the like. It is.

  FIG. 4B shows an example of a detection pattern when the user 401 falls from the bed 103 as another example of the detection pattern. For example, the head 402 of the user 401 detected in any of the attention areas A to C defined in FIGS. 3A and 3B moves to the fall detection area 420 and exceeds a predetermined time. It is assumed that the user stays in the fall detection area 420. In this case, the notification control device 101 determines that the user 401 has dropped from the bed 103. In this case, the notification control device 101 notifies a predetermined notification destination such as the nurse call system 121 of notification information including fall detection information indicating that the user 401 has fallen from the bed.

  FIG. 4C illustrates an example of a detection pattern for detecting that the user 401 who uses the bed 103 leaves the bed 103 as another example of the detection pattern. For example, when the head 402 of the user 401 detected on the bed 103 is detected in the fall detection area 420 and is not detected in the detection frame 301 within a predetermined time, the notification control device 101 It is determined that the person has left the bed. In this case, the notification control device 101 notifies the predetermined notification destination such as the nurse call system 121 of the notification information including the bed leaving detection information indicating that the user 401 has left the bed 103.

  FIG. 4D shows an example of a detection pattern for detecting that the user 401 using the bed 103 has returned to the bed 103 (hereinafter, referred to as returning to bed) as another example of the detection pattern. . For example, it is assumed that the user 401 that has not been detected in the detection frame 301 has returned to the bed 103 or the vicinity of the bed 103. In this case, for example, as shown in FIG. 4D, the head 402 of the user 401 is detected in the fall detection area 420. However, with this alone, the notification control device 101 cannot determine whether the person detected in the fall detection area 420 is the user 401 of the bed 103 or the staff of the facility.

  Thus, when the user information received from the information collection device 102 does not include the wireless ID of the medical worker, the notification control device 101 determines that the person detected in the fall detection area 420 is the user 401 of the bed 103. Judge that there is. In addition, the information collection device 102 notifies notification information including return detection information indicating that the user 401 has returned to the bed 103 to a predetermined notification destination such as the nurse call system 121, for example. On the other hand, when the user information received from the information collecting device 102 includes the wireless ID of the medical worker, the notification control device 101 determines that the person detected in the fall detection area 420 is the medical worker. Then, the process of transmitting the notification information to the predetermined notification destination is stopped.

  Thereby, when the user 401 returning to the bed 103 slides his / her hand or foot and falls down in the fall detection area 420 as shown in FIG. 4B, the notification control device 101 The presence of the user 401 in the area 420 can be immediately determined. Further, the notification control device 101 stops the process of transmitting the notification information to the predetermined notification destination when the medical worker is working in the fall detection area 420 or the like. Can be reduced.

  As described above, according to the present embodiment, the notification control device 101 that notifies the user of the situation to the predetermined notification destination based on the temperature image data captured in the predetermined imaging range 201, It is possible to reduce erroneous notifications while suppressing the delay of the notification shown.

  The “detection pattern” is information such as a name, a number, or identification information for identifying a detection pattern indicating a pattern of a temperature change. “Notification content” is information indicating notification content to be notified to a predetermined notification destination when “temperature change” corresponding to “detection pattern” is detected. “Temperature change” is information indicating a change in temperature detected in a detection area corresponding to the “detection pattern”, such as the detection frame 301, the drop detection area, and the attention areas A to C.

  For example, in FIG. 8A, “temperature change” corresponding to the detection pattern “pattern 6” indicates that the detection target (for example, the head 402 of the user 401) moves from outside the detection frame 301 to inside the detection frame 301. , Is shown. The detection unit 703 detects, for example, a change in temperature in the detection frame 301, the drop detection region, and the attention regions A to C. When the detection target moves from the outside of the detection frame 301 to the inside of the detection frame 301, the “pattern 6” is obtained. A temperature change of (an example of a predetermined detection pattern) is detected.

  The notification control unit 704 is realized by, for example, a program executed by the CPU 501 in FIG. The notification control unit 704 sends notification information indicating the state of the user 401 (object state) of the bed 103 based on the user information (object information) received by the information receiving unit 702 to the nurse call system 121 or the like. To a predetermined notification destination.

  For example, when the detection unit 703 detects a temperature change of a predetermined detection pattern and the information of the user (information of the subject) does not include a predetermined wireless ID, the notification control unit 704 sets the “detection pattern The notification information including the "notification content" corresponding to "" is notified to a predetermined notification destination. Here, the predetermined wireless ID is a wireless ID of a medical worker working at the facility.

  For example, in the detection pattern information 712 shown in FIG. 8A, it is assumed that the temperature change of the detection pattern of “pattern 6” is detected and the information of the user does not include a predetermined wireless ID. I do. In this case, the notification control unit 704 determines the “notification content” corresponding to the detection pattern “pattern 6” of the detection pattern information 712 (return information indicating that the user has returned to the bed, the bed, and the area around the bed). Notification information including the temperature image data) is notified to a predetermined notification destination.

  On the other hand, when the detection unit 703 detects the temperature change of the predetermined detection pattern and the information of the user includes the predetermined wireless ID, the notification control unit 704 corresponds to the “detection pattern”. The process of notifying notification information including “notification content” to a predetermined notification destination is stopped.

  The ID management unit (identification information management unit) 705 is realized by, for example, a program executed by the CPU 501 in FIG. 5, and stores ID management information 713 that stores a wireless ID for identifying a medical worker working at a facility. 711 and the like.

  FIG. 8B is a diagram illustrating an image of an example of the ID management information 713 according to the embodiment. In the example of FIG. 8B, the ID management information 713 includes items such as “wireless ID”, “occupation type”, “affiliation”, and “name”.

  “Wireless ID” is identification information included in a radio wave transmitted by a BLE tag possessed by a medical worker working at a facility. The “occupation” is information indicating the occupation of the medical worker corresponding to the “wireless ID”. “Affiliation” is information indicating the affiliation to which the medical worker corresponding to the “wireless ID” belongs. “Name” is information indicating the name or the like of the medical worker corresponding to “Wireless ID”.

  Using such ID management information 713, the notification control device 101 may use the bed 103 and the wireless ID received around the bed 103 in the ID management information 713 to notify the staff of the facility and the medical staff. It can be determined that the person is near the bed 103. In addition, when the bed 103 and the wireless ID received around the bed 103 are not registered in the ID management information 713, the notification control device 101 does not locate the facility staff, medical staff, and the like near the bed 103. Can be determined.

  The corresponding information providing unit (first information providing unit) 706 is realized by, for example, a program executed by the CPU 501 in FIG. The correspondence information providing unit 706 uses the wireless ID included in the user information (subject information) received by the information receiving unit 702 to respond to the user 401 of the bed 103 by a facility staff member, a medical staff member, or the like. Provide information to be visualized.

  For example, the correspondence information providing unit 706 totals the time when the wireless ID of each medical worker was received in each bed 103, and how much time each medical worker responded to the user of each bed 103 It outputs or displays information visualized in a table, a graph, or the like as to whether or not it has been done.

  The information provided by the correspondence information providing unit 706 may include temperature image data of the bed 103 and the periphery of the bed 103. Thus, for example, when the user 401 of the bed 103 suffers from violence or abuse, the staff members in the vicinity of the bed 103 and their response status are visualized. Can be expected to be effective.

  The display control unit 707 is realized by, for example, a program executed by the CPU 501 in FIG. 5 and controls display by a display device such as the LED 608 included in the information collection device 102.

  For example, the display control unit 707 determines whether there is a medical worker in the bed 103 or in the vicinity of the bed 103 based on the wireless ID included in the user information received by the information receiving unit 702. In addition, when there is a medical worker or the like around the bed 103 or the bed 103, the display control unit 707 may display information indicating that the medical worker is around the bed 103 or the bed 103 as an example. Notify the collection device 102. As another example, the display control unit 707 notifies the information collection device 102 of control information for instructing the LED 608 to blink green when there is a medical worker or the like around the bed 103 or the bed 103. Is also good.

  In response to this, when there is a medical worker around the bed 103 or around the bed 103, the information collecting apparatus 102 blinks the LED 608, for example, in green. Note that the blinking of the green color of the LED 608 is an example of display information indicating that a medical worker is present on the bed 103 or around the bed 103.

  On the other hand, when there is no medical worker around the bed 103 or around the bed 103, the display control unit 707, as an example, displays information indicating that there is no medical worker around the bed 103 or around the bed 103 as information. Notify the collection device 102. Further, as another example, the display control unit 707 notifies the information collection device 102 of control information for instructing the LED 608 not to blink green when there is no medical worker around the bed 103 or around the bed 103. May be.

  In response to this, the information collecting apparatus 102 does not blink the LED 608 in green when there is no medical worker around the bed 103 or around the bed 103.

  The voice discrimination unit (discrimination unit) 708 is realized by, for example, a program executed by the CPU 501 of FIG. 5 and uses the temperature image data and the voice data included in the user information received by the information reception unit 702. Then, the type of sound included in the audio data is determined.

  For example, the sound determination unit 708 calculates the loudness of the sound data, and if the loudness is equal to or greater than the first threshold, analyzes the temperature image data and moves the user using the bed 103. The amount (for example, the amount of movement of the head 402 of the user 401) is calculated.

  Further, for example, when the volume of the sound of the voice data is equal to or more than the first threshold and the moving amount of the user is equal to or more than the second threshold, the sound determination unit 708 determines the type of the sound, for example, Is determined to be the moaning of the person.

  On the other hand, for example, when the sound volume of the sound data is equal to or more than the first threshold value and the moving amount of the user is less than the second threshold value, the sound determination unit 708 determines the type of the sound, for example, Is determined to be snoring.

  The moaning voice and the snoring are examples of the type of sound that the voice determination unit 708 determines. The sound determination unit 708 may determine, for example, whether the type of sound included in the sound data is a sound to be notified to a predetermined notification destination.

  For example, the information collection device 102 can transmit image data (hereinafter, referred to as photograph data) obtained by photographing the bed 103 with the CMOS camera 606 to the notification control device 101 as necessary. Further, the correction unit 710 specifies the position (for example, contour) of the bed 103 using the received photograph data, and matches the position of the bed 103 with the detection frame 301, the drop detection area, and the attention areas A to Correct the position such as C.

  Preferably, when the correction unit 710 cannot correct the positions of the detection frame 301, the drop detection area, and the attention areas A to C, the display control unit 707 causes the LED 608 of the information collection device 102 to blink red, for example. In this case, the staff of the facility, medical staff, and the like determine that the position of the bed 103 is not appropriate, and adjust the bed 103 to a correct position.

  After that, the correction unit 710 corrects the positions of the detection frame 301, the drop detection area, and the attention areas A to C again, and when the correction is successful, the red blinking of the LED 608 of the information collection device 102 is ended.

In addition, when the correcting unit 710 of the notification control device 101 cannot correct the position of the detection frame 301, the display unit 727 causes the LED 608 to blink red as an example, for example.

<Process flow>
Subsequently, a flow of processing of the notification control method according to the present embodiment will be described.

[First Embodiment]
(Notification control processing)
FIG. 9 is a flowchart illustrating an example of a notification control process according to the first embodiment. This process shows an example of a notification control process executed when the notification control device 101 receives the user information transmitted from the information collection device 102.

  Here, as an example, the information collecting apparatus 102 transmits the user information including the bed 103 and the temperature image data obtained by photographing the periphery of the bed 103 and the bed ID for identifying the bed 103 at predetermined time intervals. It is assumed that the notification is transmitted to the notification control device 101. Also, when the ID receiving unit 723 receives the wireless ID, the information collection device 102 transmits the information of the user including the received wireless ID to the notification control device 101.

  In step S901, the information receiving unit 702 of the notification control device 101 receives the user information transmitted from the information collection device 102.

  In step S902, the information receiving unit 702 stores the temperature image data included in the received user information in the storage unit 711.

  Preferably, at this time, the information receiving unit 702 deletes, from the storage unit 711, the temperature image data whose predetermined storage period has elapsed.

  In step S903, the detection unit 703 of the notification control device 101 detects a temperature change of a predetermined detection pattern in one or more detection areas using the temperature image data stored in the storage unit 711.

  For example, the detection unit 703 detects the detection pattern set in the detection pattern information 712 in the detection areas such as the detection frame 301, the drop detection area, and the attention areas A to C described with reference to FIGS. Detect the temperature change of

  In step S904, the detection unit 703 of the notification control device 101 determines whether a temperature change of a predetermined detection pattern has been detected in step S903.

  When the temperature change of the predetermined detection pattern is detected, the notification control device 101 shifts the processing to step S905. On the other hand, when the temperature change of the predetermined detection pattern is not detected, the notification control device 101 ends the processing.

  In step S905, the notification control unit 704 of the notification control device 101 determines whether the information of the user received by the information receiving unit 702 includes the wireless ID of the medical worker. For example, when the information of the user received by the information receiving unit 702 includes the wireless ID registered in the ID management information 713, the notification control unit 704 includes the wireless ID of the medical worker in the information of the user. Is determined to be included.

  If the wireless ID of the medical worker is not included in the user information, the notification control unit 704 shifts the processing to step S906. On the other hand, when the user information includes the wireless ID of the medical worker, the notification control unit 704 stops the process of notifying the notification information to the predetermined notification destination and ends the process.

  In step S906, the notification control unit 704 of the notification control device 101 notifies notification information corresponding to the detected temperature change to a predetermined notification destination such as the nurse call system 121.

  By the above processing, for example, as shown in FIG. 4D, when the user 401 using the bed 103 moves into the detection frame 301, the notification control unit 704 immediately returns the user 401 to the bed. Notification information indicating the fact can be notified to a predetermined notification destination.

  On the other hand, in FIG. 4D, when the person who has moved into the detection frame 301 is a medical worker, the notification control device 101 can stop the process of notifying notification information to a predetermined notification destination. .

  As described above, according to the present embodiment, the notification control device 101 that notifies the user of the situation of the user to the predetermined notification destination based on the temperature image data captured in the predetermined imaging range has the notification indicating the status of the user. Erroneous notification can be reduced while suppressing the delay of.

(Display control processing)
FIG. 10 is a sequence diagram illustrating an example of the display control process according to the first embodiment. This process shows an example of a display control process that is performed in parallel with the notification control process shown in FIG. 9 when the notification control device 101 receives the user information transmitted from the information collection device 102. I have.

  In step S <b> 1001, the information collection device 102 transmits to the notification control device 101 information of the user including the bed 103 and temperature image data obtained by photographing the periphery of the bed 103.

  In step S1002, the display control unit 707 of the notification control device 101 determines whether or not the user information received from the information collection device 102 includes a wireless ID (predetermined ID) of a medical worker.

  Here, if the wireless ID of the medical worker is included in the user information, the processing of steps S1011 and S1012 is executed. On the other hand, when the wireless ID of the medical worker is not included in the information of the user, the processing of steps S1021 and S1022 is executed.

  In step S1011, for example, the display control unit 707 of the notification control device 101 notifies the information collection device 102 of the bed 103 or information indicating that a medical worker is present around the bed 103. As another example, the display control unit 707 may notify the information collection device 102 of control information for instructing the LED 608 to blink green.

  In step S1012, the display unit 727 of the information collection device 102 blinks the LED 608 in green in response to the information indicating that there is a medical worker or the control information for instructing the LED 608 to blink in green received from the notification control device 101. Let it.

  On the other hand, in step S1021, the display control unit 707 of the notification control device 101 notifies the information collection device 102 of information indicating that there is no medical worker around the bed 103 or around the bed 103, for example. As another example, the display control unit 707 may notify the information collection apparatus 102 of control information for instructing the LED 608 to stop blinking green.

  In step S1022, the display unit 727 of the information collection device 102 sets the LED 608 in response to the information indicating that there is no medical worker or the control information instructing the LED 608 to stop blinking green, received from the notification control device 101. Do not blink green. For example, when the LED 608 is blinking green, the display unit 727 ends the blinking of the green LED 608, and when the LED 608 is not blinking green, the display unit 727 maintains the current state.

  According to the above processing, the medical worker checks the LED 608 of the nearby information collection device 102, and if the LED is not blinking green, the BLE tag is out of order or the battery has run out. Can be recognized that the ID receiving unit 723 is in a failure state.

(Provision of correspondence information)
FIG. 11 is a flowchart illustrating an example of a process of providing correspondence information according to the first embodiment. This process shows an example of a process of providing correspondence information in which the notification control device 101 visualizes and provides a correspondence of the bed 103 to the user 401 by the medical worker.

  In step S1101, the information receiving unit 702 of the notification control device 101 receives the user information transmitted from the information collection device 102.

  In step S1102, the correspondence information providing unit 706 of the notification control device 101 determines whether the received user information includes the wireless ID (predetermined ID) of the medical worker.

  If the information of the user includes the wireless ID of the medical worker, the correspondence information providing unit 706 shifts the processing to step S1103. On the other hand, when the user ID does not include the wireless ID of the medical worker, the correspondence information providing unit 706 shifts the processing to step S1104.

  In step S1103, the correspondence information providing unit 706 of the notification control device 101 stores the wireless ID of the medical worker included in the user information in the storage unit 711 in association with the bed 103. For example, the correspondence information providing unit 706 associates the wireless ID included in the user information with the identification information for identifying the bed 103, the information collection device 102, and the like, and stores the association in the storage unit 711.

  Preferably, the information stored in the storage unit 711 by the correspondence information providing unit 706 is automatically deleted after a certain period.

  In step S1104, the correspondence information providing unit 706 of the notification control device 101 determines whether a display request for correspondence information has been received from, for example, the input device 506 or the like.

  If the display request for the correspondence information has not been received, the notification control device 101 returns the process to step S1101, and executes the processes from step S1101 again. On the other hand, if the display request of the correspondence information is received, the correspondence information providing unit 706 of the notification control device 101 shifts the processing to step S1105.

  In step S1105, the correspondence information providing unit 706 of the notification control device 101 acquires the information stored in the storage unit 711, and totals the time during which each bed 103 has received the wireless ID of the medical worker. Thus, for example, the time during which the medical staff stays at each bed 103 and around the bed 103 is calculated.

  In step S1106, the correspondence information providing unit 706 of the notification control device 101, for example, visualizes and displays the correspondence of the medical staff to the user of each bed.

  For example, the correspondence information providing unit 706 determines, based on the wireless ID of the medical worker specified in step S1104, how much time the medical worker has responded to the user of each bed 103 Is generated and displayed on the display device 507 or the like.

  Further, as a preferred example, the correspondence information providing unit 706 creates display information including information on a medical worker corresponding to the user and temperature image data on the bed 103 specified in step S1104, and displays the display information. It may be displayed on the device 507 or the like. Thus, for example, when the user 401 of the bed 103 has been assaulted or abused, it becomes easy to specify which medical worker performed the assault or abuse.

  As described above, according to the notification control device 101 according to the present embodiment, it is possible to visualize and provide (output, display, and the like) the response of the medical staff to the user of each bed 103.

[Second embodiment]
In the second embodiment, an example of a process performed when the information collection device 102 transmits information of a user to the notification control device 101 including the bed 103 and audio data around the bed 103 will be described. .

(Sound discrimination processing)
FIG. 12 is a flowchart illustrating an example of a sound determination process according to the second embodiment. This processing illustrates an example of processing in which the sound determination unit 708 of the notification control device 101 determines the type of sound in the bed 103 and the vicinity of the bed 103.

  In step S1201, the information receiving unit 702 of the notification control device 101 receives the user information transmitted from the information collecting device 102 and stores the information in the storage unit 711.

  In step S1202, the sound determination unit 708 calculates the loudness of the sound from the sound data included in the user information.

  In step S1203, the sound determination unit 708 determines whether the volume of the sound in the sound data is equal to or greater than the first threshold. It is assumed that a value for determining whether or not the sound to be determined is generated around the bed 103 and around the bed 103 is set in advance as the first threshold, for example.

  If the volume of the sound in the sound data is less than the first threshold, the sound discriminating unit 708 ends the processing. On the other hand, when the volume of the sound in the sound data is equal to or larger than the first threshold, the sound determining unit 708 shifts the processing to step S1205.

  In step S1204, the voice determination unit 708 calculates the amount of movement of the user of the bed 103 (for example, the amount of movement of the head 402 of the user 401) using the temperature image data stored in the storage unit 711. . As an example, the movement amount of the user is represented by a movement amount of a pixel (pixel) indicating a temperature corresponding to the head 402 of the user 401 in the temperature image data.

  In step S1205, the voice determination unit 708 determines whether the user's movement amount calculated in step S1204 is equal to or greater than a second threshold. As the second threshold, for example, it is assumed that a value for determining whether the user of the bed 103 is awake or sleeping is set in advance.

  When the movement amount of the user is equal to or more than the second threshold, the voice determination unit 708 determines the type of the sound generated around the bed 103 and the vicinity of the bed 103 as, for example, a moaning voice. On the other hand, when the movement amount of the user is less than the second threshold, the voice determination unit 708 determines the type of the sound generated around the bed 103 and around the bed 103 as, for example, snoring.

  Based on the determination result, the audio information providing unit 709 of the notification control device 101 can display, for example, a display screen 1300 as shown in FIG. 13 on the display device 507 or the like.

  Alternatively, the sound information providing unit 709 may notify the display screen 1300 to the nurse call system 121 or the like based on the determination result. For example, when the type of sound is determined to be a moaning in the sound determination processing illustrated in FIG. 12, the voice information providing unit 709 displays a display screen 1300 as illustrated in FIG. Notify first.

  FIG. 13 is a diagram illustrating an example of a display screen according to the second embodiment. In the example of FIG. 13, the display screen 1300 displays, for example, a character string 1301 indicating the state of the user, a temperature image 1302 photographing the periphery of the bed 103, volume information 1303, a play button 1304, and the like.

  The character string 1301 indicating the state of the user includes, for example, a bed name specifying the bed 103, a state of the user 401 of the bed 103, and a determination result by the sound determination processing in FIG. indicate.

  A temperature image 1302 taken around the bed 103 is displayed using temperature image data included in the user information received from the information collection device 102.

  Volume information 1303 visually displays the loudness of the sound around bed 103. When the play button 1304 is selected, the audio information providing unit 709 reproduces the sound acquired around the bed 103 using the acquired audio data.

  For example, in the first embodiment, when the head 402 of the user 401 is detected in the fall detection areas, the attention areas A to C, and the like, the notification control apparatus 101 notifies the notification information indicating the state of the user 401. Is notified to a predetermined notification destination. Therefore, for example, when the head 402 of the user 401 does not move from the position shown in the temperature image 1302 in FIG. 13, the notification information is not notified.

  However, by combining the first embodiment and the second embodiment, the notification control device 101 detects an abnormality of the user 401 even when the head 402 of the user 401 does not move, for example, A predetermined notification destination can be notified that an abnormality has occurred.

[Third Embodiment]
In the third embodiment, processing related to correction of the detection frame 301 by the correction unit 710 of the notification control device 101 will be described.

  When the information collection device 102 is installed on the wall or ceiling of a hospital room, if the position of the bed 103 moves from a predetermined position, the accuracy of the detection processing by the detection unit 703 may be reduced. Therefore, the notification control device 101 includes a correction unit 710 that corrects the position of the detection frame 301 in accordance with the position of the bed 103 when the position of the bed 103 is shifted with respect to the detection frame 301 of the information collection device 102. ing.

  FIG. 14 is a diagram for explaining a detection frame correction process according to the third embodiment. The information collection device 102 according to the present embodiment has a function of taking photograph data of the bed 103 using the CMOS camera 606 and transmitting the photograph data to the notification control device 101.

  For example, the photograph data acquisition unit 726 of the information collection device 102 acquires the bed 103 and the photograph data around the bed 103. Further, the information transmitting unit 724 transmits to the notification control device 101 information of the user including the temperature image data acquired by the image data acquiring unit 722 and the photograph data acquired by the photograph data acquiring unit 726.

  The information transmitting unit 724 may transmit the photograph data to the notification control device 101 separately from the user information. Further, the information collection device 102 may transmit the photograph data to the notification control device 101 when there is a request from the notification control device 101, for example, or may control the notification of the photograph data at a predetermined time interval. The information may be transmitted to the device 101.

  FIG. 14A shows an image of the photographic image 1401 and the detection frame 301 when the bed 103 is arranged at a predetermined position. When the position of the bed 103 is shifted from this state, for example, as illustrated in FIG. 14B, the correction unit 710 of the notification control device 101 detects, for example, the contour of the bed 103 from the photograph image 1401. Detects that the position of the bed 103 has shifted.

  When the correction unit 710 of the notification control device 101 detects that the position of the bed 103 has shifted, for example, as illustrated in FIG. 14C, the correction unit 710 changes the position of the detection frame 301 according to the contour of the bed 103. to correct.

  However, for example, as illustrated in FIG. 14D, when the position of the bed 103 is significantly shifted, the correction unit 710 of the notification control device 101 may not be able to detect, for example, the outline of the bed 103. In addition, if the position of the bed 103 is largely shifted in this way, even if the outline of the bed 103 can be detected, a part of the detection frame 301 may not be detected.

  In such a case, the correction unit 710 of the notification control device 101 notifies that the correction of the detection frame 301 cannot be performed, for example, by blinking the LED 608 of the information collection device 102 in red. Accordingly, for example, when the LED 608 of the information collecting apparatus 102 is blinking red, the medical worker in the vicinity of the bed 103 determines that the position of the bed 103 is shifted, and corrects the position of the bed 103. Can be. When the LED 608 of the information collecting apparatus 102 is not blinking red, the medical staff around the bed 103 can recognize that the position of the bed 103 is appropriate.

<Process flow>
FIG. 15 is a flowchart illustrating an example of a detection frame correction process according to the third embodiment. This processing shows an example of detection frame correction processing executed when the notification control device 101 corrects the detection frame 301.

  In step S1501, the correction unit 710 of the notification control device 101 acquires the photograph data of the bed 103 transmitted from the information collection device 102. For example, the correction unit 710 acquires photograph data included in the user information received by the information receiving unit 702.

  In step S1502, the correction unit 710 of the notification control device 101 detects the position of the bed 103 from the photograph data of the bed 103. For example, the correction unit 710 analyzes the photograph data and extracts the contour of the bed 103.

  In step S1503, the correction unit 710 of the notification control device 101 determines whether the position of the bed 103 is shifted with respect to the detection frame 301. For example, as illustrated in FIG. 14A, when the contour of the bed is in the correct position with respect to the detection frame 301 and the small region 302 in the detection frame 301, the correction unit 710 shifts the position of the bed 103. Judge that you have not. On the other hand, as shown in FIG. 14B, the correction unit 710 shifts the position of the bed 103 with respect to the detection frame 301 and the small area 302 in the detection frame 301 when the contour of the bed is not at the correct position. Judge that

  If the position of the bed 103 has not been shifted, the correction unit 710 shifts the processing to step S1504. On the other hand, when the position of the bed 103 is shifted, the correction unit 710 shifts the processing to step S1505.

  In step S1504, the correction unit 710 of the notification control device 101 notifies the information collection device 102 that the detection frame 301 has been successfully corrected, and ends the process. As a result, when the LED 608 is blinking red, the information collecting apparatus 102 ends the blinking of the LED 608 in red.

  On the other hand, when the process proceeds from step S1503 to step S1505, the correction unit 710 of the notification control device 101 corrects the position of the detection frame 301 according to the position of the bed 103, for example, as illustrated in FIG. For example, the correction unit 710 moves, rotates, enlarges, or reduces the size of the detection frame 301, so that the contour of the bed becomes a correct position with respect to the detection frame 301 and the small region 302 in the detection frame 301. Adjust as follows.

  In step S1506, the correction unit 710 of the notification control device 101 determines whether the correction of the detection frame 301 has been successful. For example, as illustrated in FIG. 14C, when the detection frame 301 and the small area 302 in the detection frame 301 can be detected, the correction unit 710 determines that the correction has been successful. On the other hand, as illustrated in FIG. 14D, the correction unit 710 fails to perform correction when the contour of the bed 103 cannot be detected or when the detection frame 301 and a part of the small area 302 within the detection frame 301 cannot be detected. Judge that you have done.

  If the detection frame 301 has been successfully corrected, the correcting unit 710 shifts the processing to step S1504. On the other hand, if the correction of the detection frame 301 has failed, the correction unit 710 shifts the processing to step S1507.

  In step S1507, the correction unit 710 of the notification control device 101 notifies the information collection device 102 that the correction of the detection frame 301 has failed, and returns to step S1501. Accordingly, the information collecting apparatus 102 starts blinking the LED 608 in red when the LED 608 is not blinking red, and continues blinking the LED 608 in red when the LED 608 blinks red.

  Through the above processing, the medical worker can easily determine that the position of the bed 103 is out of position, and can correct the position of the bed 103.
