Description

The present invention relates to a monitored person monitoring system for monitoring a monitored person , an operating method of the monitored person monitoring system, and a central processing unit of the monitored person monitoring system .

  Japan (Japan) is an aging society due to the improvement of living standards accompanying the post-war high economic growth, the improvement of sanitation environment and the improvement of medical standards, and more specifically, the ratio of population over 65 years to the total population It is a super-aging society with an aging rate exceeding 21%. In 2005, the total population was about 126.5 million, while the elderly population over the age of 65 was about 25.56 million. In 2020, the total population was about 124.11 million. There is also a prediction that the elderly population will be about 34.56 million. In such an aging society, nurses who need nursing or nursing care due to illness, injury, elderly age, etc., or those who need nursing care (such as those who require nursing care) are those who need nursing in a normal society that is not an aging society. This is expected to increase more than Japan, for example, is a society with a declining birthrate with a total fertility rate of 1.43 in 2013. For this reason, elderly care has been taking place where elderly families (spouse, children, siblings) who need nursing and nursing care are taking care of them.

  Nursing and care recipients enter hospitals and other facilities such as welfare facilities for the elderly (Japanese elderly law short-term entrance facilities, nursing homes for the elderly and special nursing homes for the elderly, etc.) and receive nursing and care. In such a facility, a situation in which a nurse or the like needs to be injured or fallen out of the bed, for example, by falling from the bed or falling while walking can occur. It is necessary to respond to such a situation as quickly as possible, and if such a situation is left unattended, it may develop into a more serious situation. Teachers and caregivers regularly check their safety and condition by patrols.

  However, the increase in the number of nurses and the like cannot keep up with the increase in the number of nurses and the like, and the nursing industry and the care industry are chronically short of manpower. Furthermore, since the number of nurses, caregivers and the like is reduced in the semi-night shift and night shift hours compared to the day shift hours, the work load per person increases, and thus the work load is required to be reduced. In addition, the situation of nursing care for the elderly is not an exception in the facility, and it is often seen that elderly nurses and the like care for elderly nurses and the like. In general, physical strength declines when older, so the burden of nursing etc. becomes heavier than young nurses etc. even if they are healthy, and their movements and judgments are also delayed.

  In order to reduce the labor shortage and the burden on nurses and the like, there is a demand for technology that complements nursing work and care work. For this reason, in recent years, monitored person monitoring techniques for monitoring a monitored person to be monitored, such as a care recipient, have been researched and developed.

  As one of such techniques, there is a nurse call system disclosed in Patent Document 1, for example. The nurse call system disclosed in Patent Document 1 is a nurse call slave unit that is installed in a bed and a patient calls a nurse, and a nurse call slave unit that is installed in a nurse station and responds to a call by the nurse call slave unit. A nurse call system having a nurse call parent device, a camera for imaging a patient on a bed from above the bed, and a state in which the patient wakes up from a captured image of the camera and a state in which the patient is separated from the bed State judging means for judging the occurrence of at least one of them and outputting a caution state occurrence signal, and the nurse call master unit has a notifying means for performing a notification operation upon receiving the caution state occurrence signal. The nurse call master unit has a monitor that displays a video and a video control unit that displays the captured video of the camera on the monitor when the attention state generation signal is received.

  On the other hand, in terms of safety confirmation, a single person living alone is the same as the care recipient and the like and is a person to be monitored.

  By the way, in the nurse call system disclosed in Patent Document 1, the nurse call master unit displays the patient's image on the monitor, so that the nurse can observe the patient's action by referring to the monitor image. . However, when receiving a call for a nurse call or a notice of a caution state occurrence signal, continue to watch the video on the monitor to determine whether or not to go to the patient in response to the call or the notice. Therefore, there is a risk that it will be delayed. In addition, viewing of the patient's video is preferably the minimum necessary because of patient privacy issues. There is also a desire to explain to the patient, his / her family, etc. that browsing of the patient's video is the minimum necessary.

The unit 312 is functionally configured.

  In the monitored person monitoring system MS, first, a moving image browsing time is set by a user (operator) such as a supervisor. In the setting of the video browsing time, for example, the video browsing time setting screen 51 shown in FIG. 7 is displayed on the user interface of the monitored person monitoring system MS by an unillustrated video browsing time setting request operation for requesting the setting of the video browsing time. Is displayed on the display device of the fixed terminal device SP.

  The video browsing time setting screen 51 inputs a table-type video browsing time setting input area 511 for inputting the video browsing time, and a cancellation of the video browsing time input to the video browsing time setting input area 511. A “cancel” button 512 for confirming cancellation and an “OK” button 513 for confirming input of the moving image browsing time input in the moving image browsing time setting input area 511 are provided. The moving image browsing time setting input area 511 is configured to be able to input and set a moving image browsing time for each predetermined event type, an event field 5111 for registering the event type, and a moving image corresponding to the event type.

In the example shown in FIG. 7, 60 is input as the maximum video browsing time of a record whose event type is “wake up”, and the maximum video browsing time of a record whose event type is “get out” is 30 is input, and the maximum video viewing time of the record whose event type is “falling, falling” is 15, and the maximum video of the record whose event type is “nurse call” 0 is input to the browsing time.

  When the “OK” button 513 is input on such a moving image browsing time setting screen 51, the fixed terminal device SP determines the moving image browsing time (wakeup moving image browsing time) when the event type is “wakeup”. “60” is “30” as the video viewing time (leaving video viewing time) when the event type is “getting out”, and the video browsing time when the event type is “falling, falling” (falling down) “15” as the video viewing time), and “0” as the video viewing time (nurse call video viewing time) when the event type is “nurse call” (video viewing time input setting communication signal) ) To the management server device SV.

  When receiving the video browsing time input setting communication signal, the management server device SV extracts the video browsing time corresponding to various events from the video browsing time input setting communication signal, and sets the video browsing time corresponding to the extracted various events. For example, it is stored in the SV moving image browsing time information storage unit 223 of the SV storage unit 22 in the table format shown in FIG.

  With such an operation, the moving image browsing time according to various events is stored in the SV moving image browsing time information storage unit 223 of the SV storage unit 22 in the management server device SV, and is input and set to the management server device SV.

  In the above description, the moving image browsing time corresponding to various events is input from the fixed terminal device SP that is the user interface of the monitored person monitoring system MS, and the moving image browsing time corresponding to the input various events is fixed terminal SP Is input to the management server device SV but may be the mobile terminal device TA instead of the fixed terminal device SP. If the management server device SV includes the SV input unit 24 and the SV output unit 25, the fixed setting is used. Instead of the terminal device SP, the management server device SV may be used.

  In the monitoring of the monitored person, the monitored person monitoring system MS operates as follows.

  When the mobile terminal device TA receives a login operation by a monitor (user) such as a nurse or a caregiver, for example, the mobile terminal device TA displays a standby screen for waiting for a communication signal addressed to itself by the TA monitoring processing unit 312. The information is displayed on the TA display unit 36. For example, as shown in FIG. 10, the standby screen 61 displays a menu bar area 611 for displaying a menu bar, a message indicating that it is in standby (for example, “no unsupported notification”), and an icon for displaying an icon. Main area 612, time area 613 for displaying the current time, year / month / sunday area 614 for displaying the current year / month / sunday, and user name area for displaying the name of the user currently logged in to the mobile terminal device TA 615. When such a standby screen 61 is displayed, the mobile terminal device TA waits for the TA communication IF unit 33 to receive a communication signal by the TA control unit 311.

  On the other hand, the sensor device SU uses the SU control unit 141 to sample the output of the Doppler sensor 111 of the sensor unit 11 at a predetermined sampling period corresponding to the frame rate, and obtains an image with the camera 112, and the behavior detection processing unit 142. Thus, a predetermined action (state, situation) in the monitored person Ob is detected based on the sampled and acquired output of the Doppler sensor 111 and the image of the camera 112. As a result of this detection, the monitored person Ob is preset. When the predetermined action (for example, in this embodiment, getting up, getting out of bed, falling, falling, minute movement abnormality, etc.) is detected, the notification processing unit 143 detects event information of the detected event, the sensor ID, and the monitored person Ob. A first event notification communication signal containing still image data and the like is transmitted via the network NW. To the management server SV Te. For example, when a wake-up is detected, as shown in FIG. 9, the first event notification communication signal of the wake-up event is transmitted from the sensor device SU to the management server device SV (C11). Further, for example, when a fall or fall is detected, a first event notification communication signal of a fall event or a fall event is transmitted from the sensor device SU to the management server device SV as shown in FIG. 9 (C11). Alternatively, when the sensor device SU receives an input operation of the nurse call input unit 13 by the nurse call processing unit 145, the notification processing unit 143 causes the first event notification communication signal containing the event information of the received event, the sensor ID, and the like. Is transmitted to the management server device SV via the network NW.

  When such a first event notification communication signal is transmitted from the sensor device SU, the management server device SV performs the operation shown in FIG. That is, in FIG. 8, when the management server device SV receives the first event notification communication signal from the sensor device SU by the SV control unit 211, the management server device SV receives the first event notification communication signal by the SV monitoring processing unit 212. Each information accommodated in the first event notification communication signal is stored in the SV monitoring information storage unit 221 (S11).

  Next, the management server device SV uses the video browsing time transmission setting unit 213 to set the video browsing time corresponding to the event type in the event information contained in the received first event notification communication signal in the SV storage unit 22. It is taken out from the SV moving image browsing time information storage unit 223 (S12). For example, in the example of the first event communication signal C11 that accommodates the wake-up event as the event information shown in FIG. 9, the moving image browsing time transmission setting unit 213 stores the moving image browsing time stored in the SV moving image browsing time information storage unit 223. In the information table 42, the moving image browsing time 60 [seconds] registered in the maximum moving image browsing time field 422 in the record in which the wakeup is registered in the event field 421 is extracted. Further, for example, in the example of the first event communication signal C21 that accommodates a fall event or a fall event as event information shown in FIG. 9, the moving image browsing time transmission setting unit 213 is stored in the SV moving image browsing time information storage unit 223. In the moving image browsing time information table 42, the moving image browsing time 15 [seconds] registered in the maximum moving image browsing time field 422 in the record in which the event field 421 has fallen or dropped is extracted. For example, in the example of the 1st event communication signal which accommodated the reception event as event information, the moving image browsing time transmission setting part 213 is in the moving image browsing time information table 42 memorize | stored in SV moving image browsing time information storage part 223. The moving image browsing time 0 [second] registered in the maximum moving image browsing time field 422 in the record in which the nurse call is registered in the event field 421 is extracted.

  Next, the management server device SV uses the SV monitoring processing unit 212 to create data contained in the second event notification communication signal and notify the moving image browsing time transmission setting unit 213 (S13). More specifically, the SV monitoring processing unit 212 stores the event information (event type) of the event stored in the received first event notification communication signal, the sensor ID (the sensor ID of the sensor device SU in which the event occurred) If the event is a detection event in which the predetermined action is detected, data including an image used for detection of the predetermined action is created, and this data is sent to the video browsing time transmission setting unit 213. Notification is made (S13).

  Next, the management server device SV uses the moving image viewing time transmission setting unit 213 to set the communication address of the transmission destination corresponding to the communication address of the transmission source of the received first event notification communication signal to the notification destination of the SV storage unit 22. The information is taken out from the information storage unit 222 (S14). More specifically, the moving image browsing time transmission setting unit 213 stores the received first event notification communication signal in the notification source address field 411 in the notification destination information table 41 stored in the notification destination information storage unit 222. The communication address of the notification destination registered in the notification destination address field 412 in the record in which the communication address of the transmission source is registered is extracted. For example, when the first event notification communication signal is received from the sensor device SU having the communication address “192.168.10.120” disposed in the 101st room, the transmission source of the first event notification communication signal Three communication addresses “192.168.10.0.25” registered in the notification address field 412 in the first-line record in which the communication address “192.168.10.120” is registered. , “192.168.10.26” and “192.168.10.27” are extracted. In this example, the communication address “192.168.10.25” is a communication address assigned to the mobile terminal device TA-1 owned by the caregiver NA, and the communication address “192.168.10.26”. "Is a communication address assigned to the portable terminal device TA-2 owned by the caregiver NB, and the communication address" 192.168.10.27 "is a portable terminal held by the caregiver NC (not shown). This is a communication address assigned to the device TA-3.

  Then, the management server device SV receives the event information (event type) of the event, the sensor ID (communication address) of the sensor device SU in which the event has occurred, and the event as the predetermined action by the moving image browsing time transmission setting unit 213. In the case of a detection event that detects a video, an image used for detection of a predetermined action, a video browsing time corresponding to the type of the event, and a video is displayed live on the terminal devices SP and TA for the video browsing time. A second event notification communication signal containing a command (command, command) or the like to be transmitted is transmitted to the terminal devices SP and TA having the communication address of the notification destination extracted in step S14 (S15). For example, in the example illustrated in FIG. 9, when the first event notification communication signal of the wake-up event transmitted in the process C11 is received, the management server device SV executes the above-described processes S11 to S15, thereby moving the video viewing time. A second event notification communication signal of a wake-up event for displaying a moving image live on the terminal devices SP and TA for 60 seconds is transmitted to the mobile terminal device TA. Further, for example, in the example illustrated in FIG. 9, when the first event notification communication signal of the fall event or the fall event transmitted in the process C21 is received, the management server device SV executes the above-described processes S11 to S15. The second event notification communication signal of the falling event or the falling event for displaying the moving image live on the terminal devices SP and TA for 15 seconds is transmitted to the portable terminal device TA. Further, for example, when receiving the first event notification communication signal of the reception event, the management server device SV executes the above-described processes S11 to S15, so that the moving image is displayed live for only the moving image viewing time of 0 seconds. The second event notification communication signal of the reception event to be displayed on the screen (that is, the second event notification communication signal of the reception event for disabling live video viewing) is transmitted to the portable terminal device TA.

  When such a second event notification communication signal is transmitted from the management server device SV, the terminal devices SP and TA perform the following operation. Here, the operation of the mobile terminal apparatus TA will be described, but the fixed terminal apparatus SP can operate in the same manner. That is, in FIG. 10, when the standby screen 61 is displayed on the TA display unit 36 and the reception of the communication signal is awaited, the TA monitoring processing unit 312 receives the second event notification communication signal and receives the second event notification communication signal. Each information accommodated in the two-event notification communication signal is stored in the TA monitoring information storage unit 322, the moving image browsing time is stored in the TA moving image browsing time information storage unit 323, and the received second event notification communication signal If the event type is a detected event as a result of the determination, the display processing unit 3121 receives the received second event notification communication signal. A monitoring information screen 62 (62a, 62b) for displaying monitoring information related to monitoring of the monitored person Ob stored in the TA display unit 46 is displayed. On the other hand, if the result of the determination is that the event type is a reception event, the TA display unit 46 displays a nurse call notification screen 63 for informing the reception of the nurse call by the display processing unit 3121. (C41).

  First, a case where the event type based on the event information accommodated in the second event notification communication signal is a detection event will be described. In this case, the monitoring information screen 62 automatically displays a first monitoring information screen 62a for displaying a still image, a second monitoring information screen 62b for displaying a moving image live, and displaying a moving image in a live state. Includes a third monitoring information screen 62c for notifying that the processing has been completed. For example, as shown in FIG. 10, the first monitoring information screen 62a includes a menu bar area 611, the location of the sensor device SU where the detection event has occurred, and the monitored person Ob monitored by the sensor device SU. The monitored person name area 621 for displaying the name, the icon area 622 for displaying an icon representing the elapsed time from the detection time (or the reception time) and the type of the detection event, and the sensor device SU. An image area 623 a for displaying an image (here, a still image), a “restore” button 624, and a “view LIVE” button 625 are provided. The “recovery” button 624 indicates that the user (monitoring person) of the portable terminal apparatus TA is willing to execute, for example, nursing and nursing care for the monitored person Ob monitored by the sensor apparatus SU. It is a button for inputting to the device TA. The “LIVE” button 625 is a button for inputting an instruction to display a moving image captured by the sensor device SU. In the process C31, the mobile terminal device TA displays the first monitoring information screen 62a. Therefore, when receiving the second event notification communication signal of the detected event, the portable terminal device TA switches the standby screen 61 to the first monitoring information screen 62a, displays the first monitoring information screen 62a on the TA display unit 36, and TA A still image is displayed on the display unit 36.

  Here, when the “watch live” button 625 is input, the portable terminal device TA switches the first monitoring information screen 62a to the second monitoring information screen 62b and changes the second monitoring information screen 62b to the TA display unit 36. (C32). For example, as shown in FIG. 10, the second monitoring information screen 62b includes a menu bar area 611, a monitored person name area 621, an icon area 622, and images (here, live images) captured by the sensor device SU. An image area 623 b for displaying a “moving image”, a “restore” button 624, and a “live end” button 626. The “live end” button 626 is a button for inputting an instruction to end the display of the moving image.

  In the display of the second monitoring information screen 62b, the mobile terminal device TA operates as follows. The mobile terminal device TA sends a live video to the sensor device SU having the sensor ID of the sensor device SU in which the detection event has occurred contained in the received second event notification communication signal by the TA monitoring processing unit 312. A communication signal (live video request communication signal) containing information such as a request for distribution is transmitted. The sensor device SU that has received the live video request communication signal accommodates the live video generated by the camera 112 of the sensor unit 11 in the mobile terminal device TA that is the transmission source of the live video request communication signal by the streaming processing unit 144. A communication signal (live video communication signal) is distributed by streaming playback. When receiving the live video distribution, the portable terminal device TA sets a timer at the video browsing time accommodated in the received second event notification communication signal by the TA monitoring processing unit 312 and starts timing. The mobile terminal device TA is displayed live in the image area 623b of the second monitoring information screen 62b until the input operation of the “live end” button 626 is accepted on the second monitoring information screen 62b or until the timer expires. Display a video.

  Then, when the portable terminal device TA receives an input operation of the “live end” button 626 on the second monitoring information screen 62b, the portable terminal device TA switches the second monitoring information screen 62b to the first monitoring information screen 62a and switches to the first monitoring information screen 62a. Is displayed on the TA display unit 36. Alternatively, when the timer expires, the portable terminal device TA displays the third monitoring information screen 62c for indicating that the video viewing time has elapsed and the live video display has been automatically ended, as the TA display unit 36. The first monitoring information screen 62a is displayed on the TA display unit 36 after the live video is cut off (C33). For example, as shown in FIG. 11, the third monitoring information screen 62c has a menu bar area 611, a monitored person name area 621, and a message (for example, a message indicating that the live video display has been automatically ended) Live live end display area 627 for displaying “Live finished”) and “OK” button 628, “Restore” button 624, and “Live end” button 626. The “OK” button 628 is a button for inputting, to the mobile terminal device TA, the user's consent that the live video display has automatically ended. When the input operation of the “OK” button 628 is accepted, the portable terminal device TA switches the third monitoring information screen 62 c to the first monitoring information screen 62 a and displays it on the TA display unit 36.

  For example, in the example illustrated in FIG. 9, when the second event notification communication signal of the wake-up event transmitted in the process C12 is received, the mobile terminal device TA performs the above-described process C31 and causes the TA display unit 36 to display the second event notification communication signal. 1 The monitoring information screen 62a is displayed. Here, when the input operation of the “LIVE” button 625 is accepted, the portable terminal device TA transmits a live video request communication signal to the sensor device SU by the above-described processing (C13), and the live video request communication signal. The sensor device SU that receives the message distributes the live video communication signal to the portable terminal device TA by streaming reproduction (C14). Upon receiving the live video distribution, the mobile terminal device TA sets a timer with a video viewing time of 60 [seconds] for the wake-up event. When the portable terminal device TA accepts an input operation of the “live end” button 626, the mobile terminal device ceases receiving live video (C15) and displays the first monitoring information screen 62a on the TA display unit. Alternatively, when the timer expires, the mobile terminal device TA displays the third monitoring information screen 62c on the TA display unit 36, cuts off the live video reception (C15), and then clicks the “OK” button 628. When the input operation is accepted, the first monitoring information screen 62a is displayed on the TA display unit 36.

  Further, for example, in the example illustrated in FIG. 9, when the second event notification communication signal of the fall event or the fall event transmitted in the process C22 is received, the portable terminal device TA performs the TA display by executing the process C31 described above. The first monitoring information screen 62a is displayed on the unit 36. Here, when the input operation of the “LIVE” button 625 is accepted, the mobile terminal device TA transmits a live video request communication signal to the sensor device SU by the above-described processing (C23), and the live video request communication signal. The sensor device SU that has received the message distributes the live video communication signal to the portable terminal device TA by streaming reproduction (C24). When receiving the live video distribution, the mobile terminal device TA sets a timer with a video viewing time of 15 [seconds] for the fall event or the fall event. When the portable terminal device TA accepts an input operation of the “live end” button 626, the mobile terminal device ceases receiving live video (C15) and displays the first monitoring information screen 62a on the TA display unit. Alternatively, when the timer expires, the mobile terminal device TA displays the third monitoring information screen 62c on the TA display unit 36, cuts off the live video reception (C15), and then clicks the “OK” button 628. When the input operation is accepted, the first monitoring information screen 62a is displayed on the TA display unit 36.

  When the input operation of the “recovery” button 624 is received on the first monitoring information screen 62a or the second monitoring information screen 62b, the mobile terminal device TA displays the first monitoring information screen 62a or the second monitoring information screen 62b as a standby screen. Switching to 61, the standby screen 61 is displayed on the TA display unit 36, and reception of a communication signal is awaited (C34).

  On the other hand, secondly, the case where the event type based on the event information accommodated in the second event notification communication signal is a reception event will be described. In this case, the nurse call notification screen 63 includes, for example, as shown in FIG. 10, a menu bar area 611, a monitored person name area 621, and a message indicating that a nurse call has been accepted (for example, “Nurse call”). ) To display a nurse call reception notification display area 631, a “restore” button 624, and a “speak” button 632. The “speak” button 632 is a button for inputting an instruction to connect the sensor device SU and the mobile terminal device TA via the network NW so as to be able to talk.

  In the present embodiment, since the nurse call video viewing time is [0] seconds as described above, the nurse call notification screen 63 does not include the “view LIVE” button 625, and the live video viewing is not performed. It is impossible. If the nurse call video viewing time is set to a very short time such as 1 second or 2 seconds, for example, the nurse call notification screen 63 includes a “watch live” button 625, and this “watch live” screen is displayed. When the input operation of the “” button 625 is accepted, the same operation as in the case of the detection event described above is executed.

  Here, when the “speak” button 632 is input, the portable terminal device TA switches the nurse call notification screen 63 to the busy screen 64 and displays the busy screen 64 on the TA display unit 36 (C42). For example, as shown in FIG. 10, the busy screen 64 displays a menu bar area 611, a monitored person name area 621, and a message indicating that the call is in progress (for example, “busy”). A display area 641, a “restore” button 624, and a “call end” button 642 are provided. The “call end” button 642 is a button for inputting an instruction to end the call with the sensor device SU. In the display of the mid-call screen 64, the mobile terminal device TA has a sensor having the sensor ID of the sensor device SU in which the reception event received in the received second event notification communication signal is generated by the TA monitoring processing unit 312. A communication signal (call request communication signal) containing information such as requesting a call is transmitted to the device SU. The sensor device SU that has received the call request communication signal uses the nurse call processing unit 145 to communicate a voice call communication signal (for example, VoIP (Voice over Internet Protocol) with the mobile terminal device TA that is the transmission source of the call request communication signal. ) A voice call is made by transmitting and receiving a communication signal.

  Then, when the portable terminal device TA accepts an input operation of the “end call” button 626 on the call screen 64, the mobile terminal device TA cuts the transmission / reception of the communication signal of the voice call and switches the call screen 64 to the nurse call notification screen 63. The nurse call notification screen 63 is displayed on the TA display unit 36 (C43).

  When the input operation of the “recovery” button 624 is received on the nurse call notification screen 63 or the call screen 64, the mobile terminal device TA switches the nurse call notification screen 63 or the call screen 64 to the standby screen 61 and switches to the standby screen 61. 61 is displayed on the TA display unit 36, and reception of a communication signal is awaited (C44).

  As described above, the monitored person monitoring system MS, the management server device SV as an example of the central processing unit, and the central processing method implemented therein are the SV storage unit that stores the nurse call video viewing time. 22 SV video browsing time information storage unit 223, and this nurse call video browsing time is transmitted to the terminal device SP, TA, and the terminal device SP is live only during the nurse call video browsing time in the case of a nurse call. , Display on TA. For this reason, the monitored person monitoring system MS, the management server device SV, and the central processing method perform live in the case of a nurse call by changing the nurse call video viewing time stored in the SV video browsing time information storage unit 223. Video viewing time (live video viewing time) can be varied. Since the monitored person monitoring system MS, the management server apparatus SV, and the central processing method can set the minimum nurse call video viewing time, the influence on the monitored person's privacy and communication network traffic. It is possible to observe the monitored person appropriately while considering the above.

  In many cases, the nurse call is executed when a person to be monitored such as a care recipient wants a monitor such as a caregiver to come. In the present embodiment, the nurse call video viewing time is set to 0 [seconds] as an example. Therefore, the monitored person monitoring system MS, the management server device SV, and the central processing method are live in the case of a nurse call. Therefore, it is possible to prompt the monitor to go to the monitored person as soon as possible. Since the live video cannot be viewed in the case of the nurse call, the monitored person monitoring system MS, the management server device SV, and the central processing method can protect the monitored person's privacy and distribute the moving image. Does not affect communication network traffic.

  The monitored person monitoring system MS, the management server device SV, and the central processing method accept the moving image viewing time input from the fixed terminal device SP by the SV communication IF unit 23, and the received moving image viewing time is the SV monitoring processing unit 212. In the SV moving image browsing time information storage unit 223, the moving image browsing time can be set to a desired time, for example, by a user such as a monitor, and the moving image browsing time can be varied. For example, the user can appropriately set the video viewing time according to the situation of the monitored person such as age, degree of illness or injury, and care level. Since the monitored person monitoring system MS, the management server device SV and the central processing method can set the minimum necessary video viewing time, the influence on the monitored person's privacy and communication network traffic is taken into consideration. However, the person being monitored can be observed appropriately.

  The monitored person monitoring system MS, the management server device SV, and the central processing method can set a plurality of video viewing times to desired times for each type of detected event, that is, for each type of predetermined action of the monitored person. The viewing time of live video can be varied for each type of action. For example, when the predetermined action is a fall or a fall, whether or not the monitored person has fallen or falls can be determined by whether or not the monitored person is lying down. By referring to the moving image for a relatively short time, it is possible to determine whether or not the monitored person has fallen or fallen. For this reason, the video browsing time corresponding to the case of falling (falling video browsing time) and the video browsing time corresponding to the case of falling (falling video browsing time) may be relatively short, and the monitored person monitoring system MS The management server device SV and the central processing method can set the fall video viewing time and the fall video viewing time to be relatively short. Also, for example, when the predetermined action is getting up or getting out of bed, whether or not the person to be monitored has got up or left is, for example, when the person to be monitored has a high age, the degree of illness or injury, the level of care, etc. Since the operation becomes slow, the observer needs to refer to the live video for a relatively long time. For this reason, it is preferable that the video browsing time corresponding to the case of getting up (wake-up video browsing time) and the video browsing time corresponding to the case of leaving the floor (leaving video browsing time) are relatively long. The monitoring system MS, the management server device SV, and the central processing method can set the wake-up video browsing time and the leaving video browsing time relatively long. As described above, the monitored person monitoring system MS, the management server device SV, and the central processing method can set the moving image browsing time in the case of falling or falling and the moving image browsing time in the case of getting up or leaving the floor to different times. In addition, in the case of getting up or leaving the floor, the supervisor can go to the person to be monitored and provide assistance or the like, so that falling or falling that may occur after getting up or leaving the bed can be prevented.

  In the above-described embodiment, the video viewing time is a plurality set for each type of event such as a detection event or a reception event, but is not limited to this mode (first mode). The aspect of this may be sufficient. For example, the following second to fourth modes may be used.

  FIG. 12 is a diagram illustrating a configuration of the moving image browsing time information table of the second aspect in the monitored person monitoring system of the embodiment. FIG. 13 is a diagram illustrating a configuration of a moving image browsing time information table according to a third aspect in the monitored person monitoring system according to the embodiment. FIG. 14 is a diagram illustrating a configuration of a moving image browsing time information table according to a fourth aspect in the monitored person monitoring system according to the embodiment.

  In the second mode, the moving image browsing time is plural for each of the plurality of terminal devices SP and TA, and is stored in the SV moving image browsing time information storage unit 223 of the SV storage unit 22, and the moving image browsing time transmission setting unit 213 is Of the plurality of terminal devices SP and TA stored in the SV moving image browsing time information storage unit 223, the moving image browsing time corresponding to the destination terminal device SP and TA among the plurality of terminal devices SP and TA is set as the transmission destination. The video is transmitted to the terminal devices SP and TA, and the video is displayed on the terminal devices SP and TA at the transmission destination live for the video browsing time.

  In such a second aspect, the moving image browsing time information includes, for example, the terminal device SP, TA (ie, the terminal device SP, for example, a caregiver who handles the TA) and the moving image browsing time corresponding to the terminal device SP, TA. For example, as shown in FIG. 12, the information is stored in the moving image browsing time information storage unit 223 in a table format. The moving image browsing time information table 43 shown in FIG. 12 is a terminal ID that is an identifier for identifying and identifying the terminal devices SP and TA (ie, for identifying and identifying a caregiver or the like that handles the terminal devices SP and TA). A nursing staff field 431 for registering a nursing staff ID, which is an identifier of the nursing staff), and a maximum movie viewing time field 432 for registering a video viewing time corresponding to the terminal ID (care staff ID) registered in the nursing staff field 431 in seconds. And has a record for each terminal ID (care staff ID). In the moving image browsing time information table 43 shown in FIG. 12, for example, the first record includes the terminal ID assigned to the mobile terminal device TA-1 in the care staff field 431; “TA-1” (mobile terminal device TA− 1 is registered, and “30 [seconds]” is registered in the maximum video viewing time field 432. In this embodiment, the terminal ID is a communication address. For example, TA-1 is “192.168.10.25”.

  Upon receiving notification of data contained in the second event notification communication signal from the SV monitoring processing unit 212, the video viewing time transmission setting unit 213 corresponds to the communication address of the transmission source of the received first event notification communication signal. The communication address of the transmission destination to be transmitted is extracted from the notification destination information storage unit 222 of the SV storage unit 22, and the video viewing time corresponding to the terminal ID of the terminal device SP or TA having the extracted communication address is set to the SV of the SV storage unit 22. Extracted from the video browsing time information storage unit 223, and added to the data are the extracted video browsing time and a command (command, command) for displaying the video live on the terminal devices SP and TA for the extracted video browsing time. Then, the second event notification communication signal accommodating these is transmitted to the terminal devices SP and TA having the communication address of the transmission destination.

  In such a second aspect, the monitored person monitoring system MS, the management server apparatus SV, and the central processing method set a plurality of video viewing times to desired times for each terminal device SP, TA, that is, for each supervisor. It is possible to vary the viewing time of live video for each of the terminal devices SP and TA. For example, in the case where there are many monitored persons Ob handled by the monitor, the state of the monitored person Ob is reliably determined by referring to the live video for a relatively long time, and then the monitored person Ob is moved to. The total loss is less when it is determined whether or not to go, and the above-mentioned monitored person monitoring system MS, the management server apparatus SV, and the central processing method can be used to view the moving image on the terminal apparatus of the monitoring person who has a large number of monitored persons. The time can be set to a relatively long time. In addition, for example, when a supervisor who handles the portable terminal device TA takes a relatively long time for judgment due to, for example, presbyopia, the monitored person monitoring system MS, the management server device SV, and the central processing method have a corresponding video viewing time. Can be set. Further, for example, when the monitored person Ob wants to observe the monitored person Ob for a relatively long time because the operation of the monitored person Ob is relatively slow, the monitored person monitoring system MS, the management server device SV, and the central processing method are: The moving image browsing time of the mobile terminal device TA handled by the supervisor who is responsible for the monitored person Ob can be set accordingly.

  In the third and fourth aspects, there are a plurality of moving image browsing times for each time zone, which are stored in the SV moving image browsing time information storage unit 223 of the SV storage unit 22, and the moving image browsing time transmission setting unit 213 includes the SV. The video browsing time corresponding to the time zone including the transmission time among the plurality of video browsing times for each time zone stored in the video browsing time information storage unit 223 is transmitted to the terminal devices SP and TA, and the video The moving image is displayed live on the terminal devices SP and TA for the viewing time.

  Among such third and fourth aspects, in the third aspect, the time zone coincides with a shift in work. In such a third aspect, the video viewing time information includes, for example, work shift (time zone), terminal device SP, TA (that is, for example, a caregiver who handles the terminal device SP, TA), and the duty This is information indicating the correspondence with the moving image browsing time corresponding to the shift (time zone), and is stored in the moving image browsing time information storage unit 223 in a table format as shown in FIG. 13, for example. The moving image browsing time information table 44 shown in FIG. 13 includes a shift field 441 for registering the shift of work and a care staff ID (ie, a care staff ID assigned to the caregiver who works for the shift of work registered in the shift field 441). , A nursing staff field 442 for registering a terminal device SP (terminal ID (communication address) given to the TA) handled by a nursing staff with a nursing staff ID, and a video viewing corresponding to the shift of work registered in the shift field 441 And a maximum video viewing time field 443 for registering time in seconds, and has a record for each shift (time zone) of work. In the moving image browsing time information table 44 shown in FIG. 13, for example, in the first record, “2015/05/01 early number” is registered in the shift field 441 as the shift of work, and in the care staff field 442 Nursing staff ID assigned to each of NA, nursing staff NB and nursing staff NC; “NA, NB, NC” (terminal IDs assigned to portable terminal devices TA-1, TA-2, TA-3; “TA-1, TA-2, TA-3” (“192.168.10.25, 192.168.10.26, 192.168.10.27))” is registered, and the maximum moving image viewing time field 443 is registered. In addition, “20 [seconds]” is registered.

  When the notification of the data accommodated in the second event notification communication signal is received from the SV monitoring processing unit 212, the video browsing time transmission setting unit 213 displays the video browsing time corresponding to the time zone including the transmission time as the SV storage unit. 22 of the SV video browsing time information storage unit 223, the extracted video browsing time, and the command (command, command) for displaying the video on the terminal device SP, TA live only for the extracted video browsing time, In addition to the data, the communication address of the transmission destination corresponding to the communication address of the transmission source of the received first event notification communication signal is extracted from the notification destination information storage unit 222 of the SV storage unit 22, and the extracted communication address is transmitted. First, the second event notification communication signal containing the data including the moving image browsing time and the command is transmitted.

  In the fourth aspect, the moving image browsing time information is, for example, information indicating a correspondence relationship between the time zone and the moving image browsing time corresponding to the time zone, and for example, the moving image browsing time in a table format as shown in FIG. It is stored in the information storage unit 223. The video browsing time information table 45 shown in FIG. 14 includes a time zone field 451 for registering a time zone, and a maximum video browsing time for registering a video browsing time corresponding to the time zone registered in the time zone field 451 in seconds. A time field 452 and a record for each time zone. In the video browsing time information table 45 shown in FIG. 14, for example, in the first record, “08: 0 to 12:00” is registered in the time zone field 451 as the time zone, and the maximum video browsing time field 452 is registered. , “20 [seconds]” is registered.

  When the notification of the data accommodated in the second event notification communication signal is received from the SV monitoring processing unit 212, the video browsing time transmission setting unit 213 displays the video browsing time corresponding to the time zone including the transmission time as the SV storage unit. 22 of the SV video browsing time information storage unit 223, the extracted video browsing time, and the command (command, command) for displaying the video on the terminal device SP, TA live only for the extracted video browsing time, In addition to the data, the communication address of the transmission destination corresponding to the communication address of the transmission source of the received first event notification communication signal is extracted from the notification destination information storage unit 222 of the SV storage unit 22, and the extracted communication address is transmitted. First, the second event notification communication signal containing the data including the moving image browsing time and the command is transmitted.

  The monitored person monitoring system MS, the management server device SV, and the central processing method can set a plurality of video viewing times for each time zone such as a shift of work, for example, and can perform live for each time zone. You can change the viewing time of videos. For example, normally, in the semi-night shift (late shift) and night shift hours, the number of supervisors who work is less than that of the day shift (early shift), and the above-mentioned situation occurs. The MS, the management server device SV, and the central processing method can set the moving image viewing time as appropriate according to the day shift time zone, the semi-night shift time zone, and the night shift time zone. In addition, for example, if there are few supervisors working, the situation described above is also obtained. Therefore, the monitored person monitoring system MS, the management server apparatus SV, and the central processing method depend on the number of supervisors working. The video browsing time can be set as appropriate.

  In the above-described embodiment, when the second event notification communication signal is transmitted, the moving image browsing time is accommodated in the second event notification communication signal. However, the moving image browsing time information tables 42 to 45 are stored in the sensor device SU. Or the terminal devices SP and TA.
