Description

  The present invention relates to a terminal device in a monitored person monitoring system for monitoring a monitored person, a terminal side monitoring processing method of the terminal apparatus, and the monitored person monitoring system.

  Japan (Japan) is an aging society, more specifically the ratio of population over 65 years old to the total population due to the improvement of living standards accompanying the post-war high economic growth, improvement of sanitary environment and improvement of medical standards, etc. 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 nurses who need nursing care) need to take care in a normal society that is not an aging society. It is expected to increase compared to those who are. 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 in which elderly nurses, etc., are cared for by an elderly family (spouse, child, brother).

  Nursing staff, etc. enter a facility such as a hospital or a welfare facility for the elderly (Japanese elderly law short-term entrance facility, nursing home for the elderly, special nursing home 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 the elderly care 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 installed on each bed in each hospital room such as a hospital or a welfare facility for the elderly, and is installed on a bed slave for a nurse to call a nurse and on the bedside. A plate slave unit that is detachably connected to a machine, a call-response camera installed in each hospital room for capturing images of the patient, and a call placed from a bed slave unit installed in a nurse center. And a nurse call parent device for the caller to answer and confirm the call, and the nurse call parent device is provided with the nurse call imaged by the call corresponding camera. An external call support monitor for displaying the video of the above is connected, and the external call support monitor is connected to the call support camera and detects a call from the bed slave unit. A camera selection table for selecting a corresponding camera corresponding to a camera number corresponding to a slave unit number of the plate slave unit to which the call slave unit is connected and controlled by the nurse call master unit is stored. The call corresponding camera having a camera number corresponding to the slave unit number of the slave unit connected to the call slave unit that is read from the storage unit and the caller bed slave unit read from the storage unit And a camera drive circuit for displaying the person's video on the external call monitor.

  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, a video is displayed on an external call compatible monitor and a call can be made between the nurse call parent device and the plate child device (for example, Patent Document 1). [0029] See paragraph). In general, a series of communication signals for accommodating video has a relatively large capacity. For this reason, the communication line requires a large capacity line, which increases the cost. Alternatively, when a large-capacity communication line cannot be used, the video may be interrupted or the call may be interrupted. In addition, when priority is given to establishment of a call, a delay occurs in the video. In particular, such a case is likely to occur when an existing communication line that does not assume communication of a series of communication signals that accommodate video is used.

Japanese Patent No. 4989172

  The present invention is an invention made in view of the above-mentioned circumstances, and its purpose is to prioritize establishment of a call, and to achieve both the distribution of moving images and the establishment of a call while reducing the interruption of the video and the interruption of the call. It is an object of the present invention to provide a terminal device of a monitored person monitoring system, a terminal side monitoring processing method of the terminal device, and the monitored person monitoring system that can be achieved as much as possible.

  The terminal device and the terminal-side monitoring processing method of the monitored person monitoring system according to the present invention, and the monitored person monitoring system including the terminal device are displaying the moving image received from the nurse call reception device. When the start of a voice call with the nurse call reception device is received, the video distribution condition setting for instructing the setting of the video distribution condition so that the communication capacity is reduced as compared with the video distribution condition in the case of a non-call A communication signal is transmitted to the nurse call reception device.

The monitoring information related to the monitoring of the monitored person Ob is stored (recorded) in the TA monitoring information storage unit 331 according to each information contained in the received re-reporting event notification communication signal. The displayed screen is displayed on the TA display unit 36. Then, when receiving a predetermined input operation from the TA input unit 35, the TA monitoring processing unit 322 executes a predetermined process corresponding to the input operation. More specifically, for example, when the TA monitor processing unit 322 receives a live video request operation from the TA input unit 35, the TA monitor processing unit 322 requests the sensor device SU to distribute the video and displays the video on the TA display unit 36. When the end operation is received from the TA input unit 35, the sensor device SU is requested to stop moving image distribution, and the display of the moving image on the TA display unit 36 is ended.

  When the moving image receiving processing unit 324 displays the moving image received from the sensor device SU on the TA display unit 36 and the TA input unit 35 receives the start of a voice call with the sensor device SU, A first video distribution condition setting communication signal for instructing the setting of the video distribution conditions is transmitted to the sensor device SU via the TA communication IF unit 31 so as to reduce the communication capacity compared to the video distribution conditions in the case of a call. When the TA input unit 35 accepts the end of the voice call with the sensor device SU, the TA communication IF unit 31 sends a second video distribution condition setting communication signal for instructing the setting of the video distribution condition in the case of non-call. Is transmitted to the sensor device SU. More specifically, the moving image reception processing unit 324 starts a voice call with the sensor device SU at the TA input unit 35 when the moving image received from the sensor device SU is displayed on the TA display unit 36. When received, information (video distribution) indicating that the video distribution conditions during a call stored in the TA video distribution condition storage unit 332 are taken out and that video distribution is instructed (commanded) under the extracted video distribution conditions during a call Condition setting instruction information, moving image distribution condition setting command), and the first moving image distribution condition setting communication signal containing the sensor ID corresponding to the sensor device SU that distributes the moving image to the mobile terminal device TA. It transmits to sensor device SU via 31. Then, when the TA input unit 35 accepts the end of the voice call with the sensor device SU, the video reception processing unit 324 takes out the non-call video distribution conditions stored in the TA video distribution condition storage unit 332, Video distribution condition setting instruction information (video distribution condition setting command) indicating that a video distribution is instructed (commanded) under the extracted non-call video distribution conditions, and a video is distributed to the mobile terminal device TA. A second moving image distribution condition setting communication signal containing a sensor ID corresponding to the sensor device SU is transmitted to the sensor device SU via the TA communication IF unit 31.

Is done. For example, as shown in FIG. 7, the standby screen 51 includes a menu bar area 511 for displaying a menu bar, and a standby main area for displaying a message indicating standby (for example, “no notification”) and an icon. 512, a time area 513 for displaying the current time, a year / month / sunday area 514 for displaying the current year / month / sunday, and a user name area 515 for displaying the name of the user who is currently logged in to the portable terminal device TA. Is provided.

  In FIG. 5, the sensor device SU acquires an image by the imaging unit 11 at a time interval according to a predetermined frame rate (for example, 24 f / s, 30 f / s, etc.), and the action detection process of the SU control processing unit 14 The unit 142 determines a predetermined action (state, situation) in the monitored person Ob based on the image acquired by the imaging unit 11. As a result of this determination, if it is determined that the monitored person Ob is the predetermined action set in advance (for example, in this embodiment, getting up, getting out of the floor, falling and falling) (C1), the event notification communication signal is sent to the SU communication IF. The data is transmitted to the management server device SV via the unit 15 (C2).

  When the management server device SV receives the event notification communication signal from the sensor device SU, the SV monitoring processing unit 222 of the SV control processing unit 22 performs monitoring information on monitoring of the monitored person Ob based on the received event notification communication signal. Is stored (recorded) in the SV monitoring information storage unit 231. Then, the notification destination notification destination (re-report destination, transfer destination, transmission destination) corresponding to the sensor device SU that has transmitted the received event notification communication signal is determined from the notification destination correspondence stored in the inter-device information storage unit 232. Select (search) and transmit (re-report) the event notification communication signal to the selected terminal devices SP and TA via the SV communication IF unit 21 (C3). As a result, the state (situation) of the monitored person Ob is notified to a monitor such as a nurse or a caregiver via the terminal devices SP and TA.

  When the mobile terminal device TA receives the re-report event notification communication signal from the management server device SV, the mobile terminal device TA stores monitoring information related to monitoring of the monitored person Ob based on the received re-report event notification communication signal. A screen (monitoring information screen) corresponding to the information stored in (recorded) in the unit 331 and accommodated in the received re-report event notification communication signal is displayed on the TA display unit 36 (C4). As described above, the fixed terminal device SP as an example of the terminal device operates in the same manner as the mobile terminal device TA. Here, the operation is described for the mobile terminal device TA.

  For example, as shown in FIG. 8, the monitoring information screen 52a includes a menu bar area 511, an arrangement location of the sensor device SU of the sensor ID, and the monitored person Ob monitored by the sensor device SU of the sensor ID. Monitored person name area 521 for displaying a name, icon area 522 for displaying an icon that represents an elapsed time from the reception time and a determination result, and an image captured by the sensor device SU of the sensor ID (here , A still image) image area 523a, a “corresponding” button 524, a “speak” button 525, and a “watch live” button 526. The “corresponding” button 524 indicates that the user of the mobile terminal device TA has the intention to execute the response such as nursing to the monitored person Ob monitored by the sensor device SU of the sensor ID. It is a button for inputting to the portable terminal device SU an instruction to input to the device TA and notify the other terminal devices SP and TA that the intention has been input. The “speak” button 525 is a button for inputting an instruction to connect the sensor device SU of the sensor ID and the mobile terminal device TA so as to be able to talk over the network NW. The “LIVE” button 526 is a button for inputting an instruction to distribute and display a moving image captured by the sensor device SU with the sensor ID. An icon that symbolically represents the correspondence between the sensor ID, the location of the sensor device SU of the sensor ID, and the name of the monitored person Ob monitored by the sensor device SU of the sensor ID, and the determination result. Is stored in the TA storage unit 33 as one of the various predetermined data by being notified from the management server device SV or by being input in advance.

  When such a monitoring information screen 52 a is displayed on the TA display unit 36, when the user performs an input operation on the “LIVE” button 526 (C 5), the portable terminal device TA is switched to the TA monitoring processing unit 322. A communication signal (video distribution request communication signal) containing information such as a request for live video distribution to the sensor device SU having the sensor ID contained in the received re-report event notification communication signal. Is transmitted via the TA communication IF unit 31 (C6). The sensor device SU that has received the video distribution request communication signal causes the video distribution processing unit 144 to transfer the video generated by the imaging unit 11 to the mobile terminal device TA that is the transmission source of the video distribution request communication signal that requested the video. The streaming is distributed via the SU communication IF unit 15 in accordance with the moving image distribution conditions stored in the SU moving image distribution condition storage unit 161 (C7). When receiving the live video distribution, the portable terminal device TA displays the distributed video on the TA display unit 36 by streaming reproduction by the TA monitoring processing unit 322 (C8). For example, as shown in FIG. 9, the monitoring information screen 52b that displays the live moving image is an image region 523b that displays a moving image instead of the image region 523a that displays a still image in the monitoring information screen 52a illustrated in FIG. In addition, a “LIVE END” button 527 is provided instead of the “VIEW LIVE” button 526. The “live end” button 527 is a button for inputting an instruction to end (stop) the distribution of the moving image captured by the sensor device SU of the sensor ID and end (stop) the display.

  When the user presses the “speak” button 525 while the moving image received from the sensor device SU is displayed on the TA display unit 36 on the monitoring information screen 52b (C9), the mobile terminal device TA transmits a communication signal (call communication) containing information such as requesting a voice call to the sensor device SU having the sensor ID contained in the received re-report event notification communication signal by the TA nurse call processing unit 323. Request communication signal) is transmitted via the TA communication IF unit 31 (C10). Then, the mobile terminal device TA uses the video reception processing unit 324 to extract the on-call video distribution conditions stored in the TA video distribution condition storage unit 332 and instruct the video distribution under the extracted on-call video distribution conditions ( Command distribution condition setting instruction information (moving image distribution condition setting command) indicating that the instruction is to be performed) and a sensor ID corresponding to the sensor device SU that is distributing the moving image to the mobile terminal device TA (in this example, the received re-transmission command). The first video distribution condition setting communication signal containing the sensor ID accommodated in the notification event notification communication signal is sent to the sensor device SU having the sensor ID accommodated in the received re-report event notification communication signal. Transmission is performed via the communication IF unit 31 (C11). Note that the call request communication signal and the first video distribution condition setting communication signal may be combined into one communication signal. In addition, the “speak” button 525 on the monitoring information screens 52a and 52b is changed to an “end” button (not shown) that is a button for inputting a voice call end instruction.

  The sensor device SU that has received the call request communication signal uses the SU nurse call processing unit 143 to use the SU sound input / output unit 12 and the like to communicate with the mobile terminal device TA that is the transmission source of the received call request communication signal. For example, a voice call is performed with the portable terminal device TA by transmitting / receiving a VoIP communication signal (call communication signal) via the SU communication IF unit 15 (C12).

  Then, the sensor device SU that has received the first video distribution condition setting communication signal, by the video distribution processing unit 144, receives the video distribution condition (video communication condition during call) accommodated in the received first video distribution condition setting communication signal. ) To rewrite and update the contents stored in the SU video distribution condition storage unit 161. Therefore, the sensor device SU causes the moving image distribution processing unit 144 to transfer the moving image generated by the imaging unit 11 to the mobile terminal device TA that is the transmission source of the moving image distribution request communication signal in the process C6 and to the SU moving image distribution condition storage unit 161. In accordance with the rewritten and updated moving image distribution conditions (calling moving image distribution conditions), streaming is distributed via the SU communication IF unit 15 (C13). As a result, during a call, the moving image is distributed under a moving image distribution condition in which the communication capacity is reduced compared to the moving image distribution condition in the case of a non-call.

  Here, when the user performs an input operation on the “end” button (not shown) for inputting an instruction to end the voice call (C14), the TA terminal call processing unit 323 causes the portable terminal device TA to perform a voice call. A communication signal containing information such as a request to terminate the voice call to the sensor device SU at the call destination (that is, the sensor device SU having the sensor ID accommodated in the received re-report event notification communication signal) A call end communication signal) is transmitted via the TA communication IF unit 31 (C15). Then, the mobile terminal device TA extracts the non-call video distribution conditions stored in the TA video distribution condition storage unit 332 by the video reception processing unit 324, and distributes the video according to the extracted non-call video distribution conditions. Video distribution condition setting instruction information (video distribution condition setting command) indicating instruction (command) and a sensor ID corresponding to the sensor device SU that distributes the video to the mobile terminal device TA (in this example, the reception) The second video distribution condition setting communication signal containing the sensor ID accommodated in the rereport event notification communication signal) to the sensor device SU having the sensor ID accommodated in the received rereport event notification communication signal. And transmitted via the TA communication IF unit 31 (C16). Note that the call end communication signal and the second moving image distribution condition setting communication signal may be combined into one communication signal.

  The sensor device SU that has received the call end communication signal terminates the voice call with the mobile terminal device TA that is the transmission source of the received call end communication signal by the SU nurse call processing unit 143.

  Then, the sensor device SU that has received the second moving image distribution condition setting communication signal causes the moving image distribution processing unit 144 to move the moving image distribution condition (non-call moving image distribution) accommodated in the received second moving image distribution condition setting communication signal. Condition), the contents stored in the SU video distribution condition storage unit 161 are rewritten and updated. Therefore, the sensor device SU causes the moving image distribution processing unit 144 to transfer the moving image generated by the imaging unit 11 to the mobile terminal device TA that is the transmission source of the moving image distribution request communication signal in the process C6 and to the SU moving image distribution condition storage unit 161. In accordance with the rewritten and updated moving image distribution condition (non-call moving image distribution condition), streaming is distributed via the SU communication IF unit 15 (C17). When receiving the live video distribution, the portable terminal device TA displays the distributed video on the TA display unit 36 by streaming reproduction by the TA monitoring processing unit 322 (C18). As a result, at the time of non-calling, the moving-image distribution conditions in the case of non-calling are automatically restored along with the end of the voice call, and the moving images are distributed under the restored moving-image distribution conditions.

  When the “live end” button 527 is input by the user (C19), the mobile terminal device TA uses the TA monitoring processing unit 322 to detect the moving image distribution source sensor device SU (that is, the received re-report event). A communication signal (moving image distribution end communication signal) containing information such as requesting the end of moving image distribution is transmitted via the TA communication IF unit 31 to the sensor device SU having the sensor ID accommodated in the notification communication signal. (C20). As a result, the distribution of the moving image is terminated, and the monitoring information screen 52a is displayed on the TA display unit 36. The still image contained in the received re-report event notification communication signal may be displayed in the image area 523a of the monitoring information screen 52a, and is displayed when the moving image distribution end communication signal is transmitted. The moving image that has been displayed may be continuously displayed as a still image.

  The operation when the input operation in the portable terminal device TA is received while the monitored person monitoring system MS is operating will be described. In FIG. 6, when the TA control processing unit 32 receives an input operation on the touch panel constituted by the TA input unit 35 and the TA display unit 36 (S11), the TA control processing unit 32 determines the type of the received input operation (S12).

  As a result of this determination, when the received input operation is an operation of the “watch live” button 526 (“watch live”), as described in process C6, the mobile terminal device TA performs the TA monitoring process. The unit 322 transmits a moving image distribution request communication signal to the sensor device SU having the sensor ID accommodated in the received re-report event notification communication signal (S13), and ends this process.

  When the received input operation is an operation of the “speak” button 525 as a result of the determination in the process S12 (“speak”), the TA control processing unit 32, as described in the processes C10 and C11, The nurse call processing unit 323 transmits a call request communication signal to the sensor device SU having the sensor ID accommodated in the received re-report event notification communication signal. The processing unit 324 retrieves the on-call moving image distribution condition from the TA moving image distribution condition storage unit 332, the moving image distribution condition setting instruction information regarding the retrieved on-call moving image distribution condition, and the sensor ID corresponding to the moving image distribution source sensor device SU. Is transmitted to the sensor device SU (S14), and the process ends.

  As a result of the determination in the process S12, when the received input operation is an operation of the “live end” button 527 (“live end”), as described in the process C20, the TA control processing unit 32 The monitoring processing unit 322 transmits a moving image distribution end communication signal to the moving image distribution source sensor device SU (S15), and ends this processing.

  As a result of the determination in the step S12, when the received input operation is an “end” operation (not shown) (“end”), the TA control processing unit 32 as described in the processing C15 and the processing C16. The TA nurse call processing unit 323 transmits a call end communication signal to the voice call destination sensor device SU, and when moving image distribution is in progress, the moving image reception processing unit 324 stores the TA moving image distribution condition storage. The non-call video distribution condition is extracted from the unit 332, and the second video distribution condition containing the video distribution condition setting instruction information related to the extracted non-call video distribution condition and the sensor ID corresponding to the sensor device SU of the video distribution source A setting communication signal is transmitted to the sensor device SU (S16), and this process is terminated.

  In addition, as a result of the determination in the process S12, the received input operations include the operations of the “watch live” button 526, the operation of the “speak” button 525, the operation of the “live end” button 527, and “ In the case of another operation that is not one of the operations of the “End” button (others), the TA control processing unit 32 executes an appropriate process according to the other and ends this process.

  In the above-described embodiment, the TA sound input / output unit 34 and the TA nurse call processing unit 323 of the TA control processing unit 32 are connected via a terminal side communication unit (in this embodiment, the TA communication IF unit 31 is an example). This corresponds to an example of a terminal-side voice call unit that makes a voice call with a nurse call reception device (in this embodiment, the sensor device SU is an example thereof). The “speak” button 525 and the “end” button 532 of the touch panel constituted by the TA input unit 35 and the TA display unit 36 and the TA control processing unit 32 that executes the processing are a nurse call accepting device (in this embodiment, a sensor device). SU corresponds to an example of a terminal-side voice call accepting unit that accepts the start and end of a voice call with SU.

  As described above, the monitored person monitoring system MS, its terminal devices SP and TA, and its terminal side monitoring processing method according to the present embodiment use the moving image received from the sensor device SU (an example of a nurse call reception device). When the start of a voice call is accepted while displaying on the TA display unit, the second is for instructing the setting of the video distribution condition so that the communication capacity is reduced as compared with the video distribution condition in the case of a non-call. Since the moving image reception processing unit 324 that transmits a moving image distribution condition setting communication signal to the sensor device SU is provided, the communication capacity of the moving image distribution condition is reduced compared to the moving image distribution condition in the case of a non-call with the start of a voice call. To be changed. For this reason, the monitored person monitoring system MS, the terminal devices SP and TA, and the terminal-side monitoring processing method give priority to establishment of a call, reduce video interruptions and call interruptions, and distribute video and establish calls. Can be achieved as much as possible.

  The monitored person monitoring system MS, the terminal devices SP and TA, and the terminal-side monitoring processing method can change the one or more of the moving image frame rate, the moving image frame size, and the moving image color number to make a non-calling operation. The setting of the moving image distribution condition can be instructed so that the communication capacity is reduced as compared with the moving image distribution condition.

  In the monitored person monitoring system MS, the terminal devices SP and TA, and the terminal side monitoring processing method, when the end of the voice call is received, the moving image reception processing unit 324 instructs the setting of the moving image distribution condition in the case of non-calling. Since the second moving image distribution condition setting communication signal for transmitting is transmitted to the sensor device SU, it is possible to automatically return to the moving image distribution condition in the case of a non-call as the voice call ends.

  In the above-described embodiment, the moving image reception processing unit 324 of the mobile terminal device TA displays the moving image received from the sensor device SU on the TA display unit 36, and the TA input unit 35 uses the sensor device SU. When the start of the voice call is received, the first video distribution condition setting communication signal for instructing the setting of the video distribution condition so as to reduce the communication capacity compared to the video distribution condition in the case of non-call is TA. Although it transmitted to the sensor device SU via the communication IF unit 31, the frame rate of the moving image may be 0 for the moving image distribution condition accommodated in the first moving image distribution condition setting communication signal. According to this, since the frame rate of the moving image distribution condition is 0, the distribution of the moving image is substantially stopped and a voice call can be made more reliably.

  FIG. 10 is a diagram illustrating an example of a call screen displayed on the mobile terminal device in the monitored person monitoring system according to the embodiment. In this case, the video reception processing unit 324 received the start of a voice call with the sensor device SU at the TA input unit 35 while displaying the video received from the sensor device SU on the TA display unit 36. In this case, a first moving image distribution condition setting communication signal for instructing setting of a moving image distribution condition in which the frame rate of the moving image is 0 is transmitted to the sensor device SU via the TA communication IF unit 31, and A call screen indicating that a voice call is possible is displayed on the TA display unit 36. For example, as shown in FIG. 10, the in-call screen 53 includes a menu bar area 511, a monitored person name area 521, an icon area 522, and a message indicating that a call is possible (for example, “in call”). ) And an icon for displaying a call main area 531, a “corresponding” button 524, and an “end” button 532. The “end” button 532 is a button for inputting an instruction to end the voice call with the sensor device SU.

  In this case, the TA display unit 36 uses the TA monitoring processing unit 322 instead of the call screen 53 to set the first moving image distribution condition for instructing the setting of the moving image distribution condition where the moving image frame rate is 0. The display of the moving image displayed when the communication signal is transmitted to the sensor device SU via the TA communication IF unit 31 may be continued as a still image. According to this, since the image of the moving image displayed when the first moving image distribution stop communication signal is transmitted continues to be displayed as a still image, for example, a user such as a monitor can monitor the monitored person Ob during the call. You can also check the situation in the image.

  In the above-described embodiment, as an example, the terminal-side voice call accepting unit that accepts the start and end of the voice call includes the “speak” button 525 and “end” of the touch panel configured by the TA input unit 35 and the TA display unit 36. ”Button 532 and a TA control processing unit 32 for executing the process, the terminal side voice call accepting unit is replaced with“ speak ”button 525 and“ end ”button 532 or“ speak ”. In addition to the button 525 and the “end” button 532, a voice activation function that accepts the start and end of the voice call according to the presence or absence of voice may be used. In this voice activation function, for example, the TA control processing unit 32 determines that the start of the voice call has been accepted when the volume of the sound input to the TA sound input / output unit 34 is equal to or higher than a preset first threshold value. The same processing as when the input operation of the “speak” button 525 is received is executed, and the volume of the sound input to the TA sound input / output unit 34 is equal to or lower than a preset second threshold value, and the state is in advance. If it has been continued for a predetermined time or more, it is determined that the end of the voice call has been accepted, and the same processing as when the input operation of the “end” button 532 is accepted is executed. According to this, since the mobile terminal device TA has a voice activation function, the user can input the start and end of a voice call with the sensor device SU to the mobile terminal device TA without performing an input operation.

  In addition, when the mobile terminal device TA is provided with the voice activation function in addition to the “speak” button 525 and the “end” button 532, on / off of the voice activation function may be displayed on the TA display unit 36. FIG. 11 is a diagram illustrating another example of a monitoring information screen displaying a still image displayed on the mobile terminal device in the monitored person monitoring system according to the embodiment. For example, as shown in FIG. 11, the monitoring information screen 52 c accompanied with such a voice activation function on / off display is displayed on the monitoring information screens 52 a and 52 b shown in FIGS. 8 and 9. A VAF on / off display area 541 for display is provided. In the example shown in FIG. 11, it is displayed in the VAF on / off display area 541 that the voice activation function is on (VAF; ON). FIG. 11 shows a monitoring information screen 52c configured by further providing a VAF on / off display area 541 on the monitoring information screen 52a shown in FIG. According to this, ON / OFF of the voice activation function is clearly indicated on the TA display unit 36.
