Description

The present invention relates to a communication system suitable for use in a nursing care facility or the like.

In Japan, the birthrate is declining and the population is aging rapidly due to the increase in the average life expectancy of the people and the decrease in the birth rate. Along with this, the number of hospitals and welfare facilities for the elderly that accommodate people in need of long-term care (people requiring long-term care) is increasing, but the number of nurses and caregivers is chronically insufficient due to harsh working conditions. It is causing a serious situation that there is no such thing. Especially at night, a small number of people have to watch over many people requiring long-term care, which increases the burden on caregivers and the like, which is one of the causes of further labor shortage.

In order to reduce the burden on caregivers and the like, there is a need for technology that supports long-term care work. As an example, various techniques for monitoring a person requiring long-term care have been developed in order to make a machine perform a part of the work of a caregiver or the like.

In Patent Document 1, when an abnormality detecting device detects an abnormality of a monitoring target such as a person requiring nursing care, an image of the monitoring target is imaged, and the image data of the monitoring target is transmitted to an external terminal via the Internet or the like. The technology for remotely monitoring the current status of the monitored object is disclosed by transmitting.

Japanese Unexamined Patent Publication No. 2005-253025 Japanese Patent No. 3155908

Such a mobile terminal TA can be configured by a portable communication terminal device such as a so-called tablet computer, a smartphone, or a mobile phone.

Next, the operation of the long-term care support system in the embodiment will be described. A general-purpose mobile terminal that uses an OS such as "Android (registered trademark)" can execute multiple installed applications, so it can be used for this nursing care support system at a lower cost than a dedicated product. it can. By the way, an OS such as "Android (registered trademark)" has a function of creating telephone directory data in which the destination terminal information and the destination user information are associated with each other in order to make an extension connection. By using this function, it is possible to make an extension call between mobile terminals via the PBX. That is, an extension connection can be established with the other party's mobile terminal by making an extension connection request including the other party's terminal information to the PBX from any of the mobile terminals.

Here, when there is an extension connection request including the destination terminal information, the PBX establishes the extension connection with the mobile terminal specified based on the destination terminal information. On the other hand, since caregivers and the like work in shifts in ordinary care facilities, one mobile terminal may be shared by a plurality of caregivers and the like. Therefore, even if an extension connection is established to a mobile terminal specified based on the other party terminal information, it is not necessarily the other party who made an extension call, and there is a risk of confusion. According to the present embodiment, it is possible to make an extension call to a desired party without any trouble.

Here, the entire nursing care support system MS according to the present embodiment will be described. When the sensor box SB is activated, the monitoring operation is started by executing the control processing program. First, one of the caregivers (user 0006) who started work turns on the main switch of his mobile terminal TA. Then, a login screen as shown in FIG. 4 described later is displayed. A standard login screen is displayed on a mobile terminal that uses an OS such as "Android (registered trademark)", but here it is customized to display the login screen as shown in FIG. 4 first. ..

FIG. 3 is a ladder chart showing communication between the management server SV, the mobile terminals TA-6, TA-7, and the PBX. FIG. 4 is a diagram showing a login screen of the mobile terminal TA-6, FIG. 5 is a diagram showing a screen when the monitoring application of the mobile terminal TA-6 is executed, and FIG. 6 is a diagram showing the screen of the mobile terminal TA-7. It is a figure which shows the screen when the extension call mode is selected, FIG. 7 is a figure which shows the screen when the extension call mode is selected of the mobile terminal TA-6, and FIG. 8 is a figure which is stored in the mobile terminal TA-7. It is an example of the telephone book data, and FIG. 9 is an example of the telephone book data stored in the mobile terminal TA-6. In the telephone directory data shown in FIGS. 8 and 9, the terminal name is the other party terminal information and the user name is the other party user information.

Here, the mobile terminals TA-1 to TA-3 and TA-5 (not shown in FIG. 3) and TA-7 are already logged in, and as shown in step S101 of FIG. 3, the subject Ob is watched over ( It is assumed that the caregiver user 0006 logs in from the mobile terminal TA-6 from the state of monitoring).

Before the user 0006 logs in, the telephone directory data shown in FIG. 8A is stored in the TA storage unit 32 of the mobile terminal TA-7. In the telephone directory data shown in FIG. 8A, the user is not logged in from the mobile terminals TA-4 and TA-6, and the user is blank, and the mobile terminal TA-7 means "OWN". Is recorded. In this state, when the mobile terminal TA-7 shifts to the extension call mode (details will be described later), as shown in FIG. 6A, the main area 612 of the TA display unit 36 is based on the stored telephone directory data. Is displayed as the user names "0001", "0002", "0003", and "0005" that are currently logged in except for oneself, from which the other party who can make an extension call can be specified. The management server SV also stores telephone directory data (basic telephone directory data) that associates all mobile terminals logged in at the present time with user names.

In step S102 of FIG. 3, a login operation is performed by the user 0006 from the mobile terminal TA-6, so that the monitoring system is activated in the mobile terminal TA-6. More specifically, on the login screen shown in FIG. 4 of the mobile terminal TA-6, the user taps the triangle mark MK1 at the right end of the "user name" input field CL1 to display a plurality of options. Then, tap and select your user name "User 0006" (user ID: the name of the caregiver may be used), and then use the number key NK displayed below it in the "Pass" input field CL2. And enter a 4-digit number. After that, the user taps the button B11 to complete the login operation. The path input may be omitted.

By the login operation in step S102 in FIG. 3, a login request signal including the user name (user ID) "0006" as user information and the terminal ID of the mobile terminal TA-6 is sent from the mobile terminal TA-6 to the management server. It is transmitted to the SV (C11). The management server SV that received the login request signal refers to the database stored in the internal memory, confirms that the user name and path match, and performs login authentication (step S103), indicating that the login authentication was successful. The response signal is transmitted to the mobile terminal TA-6 (C12). In the mobile terminal TA-6 that has received such a response signal, the monitoring application is activated to support the monitoring of the target person Ob as described later (step S104). Although not shown, if the user name and the path do not match, the management server SV sends a failure signal to the mobile terminal TA-6 to prompt the login operation again.

In step S105 in parallel with the login authentication, the management server SV updates the basic telephone directory data stored by itself and creates update information in response to a new login of the user 0006 from the mobile terminal TA-6. .. At present, the combination of the mobile terminal TA-6 and the user 0006 is not recorded in the telephone directory data of all the mobile terminals logged in. Therefore, the management server SV adds and updates the combination of the newly logged-in mobile terminal TA-6 and the user 0006 to the basic phonebook data in addition to the combination of the logged-in mobile terminal and the user name. A copy of the basic telephone directory data is transmitted to the mobile terminal TA-6 (C13).

When the mobile terminal TA-6 receives a copy (update information) of the basic telephone directory data, it stores this in its own TA storage unit 32 in step S106 (if the previous telephone directory data remains). (Replace) changes the user name of the mobile terminal TA-6 to "OWN" which means itself. The updated telephone directory data is as shown in FIG. 9A, that is, the mobile terminal TA-4 is not logged in, and the mobile terminal TA-6 is recorded as "OWN". In this state, when the mobile terminal TA-6 shifts to the extension call mode, as shown in FIG. 7A, the main area 612 is currently logged in except for oneself based on the updated telephone directory data. The existing user names "0001", "0002", "0003", "0005", and "0007" are displayed, from which the other party who can make an extension call can be specified.

In parallel with the above, the management server SV transmits updated information including the combination of the newly logged-in mobile terminal TA-6 and the user 0006 to all logged-in mobile terminals other than the mobile terminal TA-6 (). C14). The mobile terminal that has received the update information updates by additionally recording this combination in the telephone directory data stored in its own TA storage unit 32 (step S107). A copy of the updated phonebook data may be sent to all logged-in mobile terminals to replace the stored ones. As described above, for example, the telephone directory data updated on the mobile terminal TA-7 is as shown in FIG. 8 (b), that is, the telephone directory data shown in FIG. 8 (a) is displayed on the mobile terminal TA-6. The user name 0006 is added in association with it. That is, the combination of the mobile terminal TA-6 and the user name 0006 becomes effective in the telephone directory data.

Here, support for monitoring (watching) the target person Ob by executing the watching application in step S104 (the same applies to step S101) will be described. When the monitoring application is activated, the mobile terminal TA-6 displays a standby screen for waiting for a communication signal addressed to its own device on the TA display unit 36 by the TA processing unit 312. As shown in FIG. 5A, for example, this standby screen has a menu bar area 611 for displaying a menu bar, a message indicating that the standby is in progress (for example, "There is no unsupported notification"), a date, and a current state. It is provided with a standby main area 612 for displaying a user name 63 (0006) and the like logged in to the mobile terminal TA-6 at time 612. While displaying such a standby screen, the mobile terminal TA-6 waits for a communication signal transmitted from the management server SV at the TA communication IF unit 33 by the TA control unit 311.

Although not shown, the sensor box SB that monitors each target person Ob acquires the image data of the target person Ob by the camera unit and analyzes the image data. As a result of this analysis, when a predetermined event (getting up, getting out of bed, falling, falling) is detected, the sensor box SB stores the image data before and after the event in the built-in memory and determines what kind of event has occurred. The event information to be shown and the notification signal including the communication address are transmitted to the management server SV via the network NW.

When such a notification signal is transmitted from the sensor box SB, the management server SV determines who the resident is (here, Mr. B) based on the information of the sensor box SB included in the notification signal. Further, from the event information of the notification signal, it is determined whether or not it corresponds to the type of notification event (here, fall or fall: specific state) corresponding to the resident (Mr. B). Then, when the event information of the received notification signal indicates a notification event, it is determined to notify the mobile terminal. On the other hand, when the event information of the received notification signal does not indicate the notification event (in the case of Mr. B, getting up or getting out of bed), it is decided not to notify the mobile terminal, and the next notification signal is awaited.

When the management server SV decides to notify the terminal, the caregiver (user 0006) in charge of the resident (Mr. B) selects the mobile terminal TA-6, and the RM-2 room falls or falls. A notification signal (event signal) including the generated information is transmitted to the selected mobile terminal.

When such a notification signal is transmitted from the management server SV, the mobile terminal TA-6 switches the screen display of the TA display unit 36 by the TA processing unit 312 to, for example, the one shown in FIG. 5 (b). In the example shown in FIG. 5B, in the main area 612, the name of the room where the event occurred (Room RM-2), the name of the resident of the room (Mr. B), and the icon IC1 indicating a fall or fall. , The time difference (0 minutes) between the notification time and the present is displayed. At the same time, buttons B1 (corresponding), B2 (speaking), B3 (viewing the stored image), and B4 (viewing the live image) are displayed in the main area 612.

Here, when the caregiver touches (also referred to as tap) the button B3 or B4, the TA input unit 35 of the mobile terminal TA-6 reacts, and the TA control unit 311 determines that the image request has been made, and TA communication. A request signal is transmitted from the IF unit to the management server SV via the network NW. Here, the request signal includes a request type (stored video or live video). The management server SV relays the request signal and transmits it to the target sensor box SB. The request signal may be directly transmitted to the sensor box SB.

The sensor box SB that has received the request signal determines the request type in the request signal. When the caregiver touches the button B3, a request signal requesting a stored image is output from the mobile terminal TA-6, so that the sensor box SB that receives this is requested for the stored image via the management server SV. It is determined that the image data is read from the sensor box SB and transmitted to the management server SV via the network NW. Alternatively, when the caregiver touches the button B4, a request signal requesting a live image is output from the mobile terminal TA-6, so the sensor box SB that receives this signal via the management server SV requests the live image. The live image captured by the camera unit is encoded and transmitted from the sensor box SB to the management server SV via the network NW.

On the mobile terminal TA-6 that has received the image data, the TA processing unit 312 switches the screen display of the TA display unit 36 to, for example, the one shown in FIG. 5 (c). In the example shown in FIG. 5 (c) in which the stored image is requested, the image (image) IMG of Mr. B before and after the fall in the RM-2 room is displayed in the main area 612. The caregiver can immediately determine whether or not the condition should be dealt with. If the caregiver cannot make a judgment just by looking at the image IMG, the caregiver can directly talk between Mr. B and the caregiver via the sound input / output unit (not shown) of the sensor box SB by touching the button B2. Therefore, the situation can be accurately judged.

When the caregiver who saw the displayed icon IC1 is near the RM-2 room where the event occurred, he / she can immediately rush without looking at the image. Therefore, in such a case, by touching the button B1, information to the effect that the caregiver directly responds is transmitted to, for example, the fixed terminal SP.

By the way, when any of the screens shown in FIG. 5 is displayed, for example, a caregiver may want to make an extension call to a colleague. In such a case, it is convenient to be able to make an extension call between mobile terminals using PBX. Hereinafter, an extension connection using PBX from the mobile terminal TA-7 used by user 0007 to the mobile terminal TA-6 used by user 0006 will be described.

When the caregiver (user 0007) taps the icon IC2 (see FIG. 5) of the menu bar area 611 displayed on the TA display unit 36 of the mobile terminal TA-7 used by the caregiver (user 0007), the mode shifts to the extension call mode. As a result, the screen shown in FIG. 5 is switched to the screen shown in FIG. 6B, and based on the updated telephone directory data, the user name "0001" currently logged in to the main area 612 except for himself / herself. , "0002", "0003", "0005", "0006" will be displayed. The user 0007 can specify the other party to whom he / she wants to make an extension call. At this time, since the user who is not logged in cannot be specified, the user can make an extension call without confirming whether or not the other party is logged in. As is clear, if there is only one user logged in, no user name will be displayed on the screen, indicating that an extension call cannot be made.

To make an extension call to user 0006, tap user 0006 on the display screen to specify it, and then tap the displayed icon IC4 (step S108 in FIG. 3). At this time, the terminal TA-7 refers to its own telephone directory data, selects the destination terminal information (TA-6) associated with the designated user 0006, and refers to the PBX with respect to the destination terminal. An extension connection request signal including information (TA-6) is transmitted (C15). Upon receiving this, the PBX identifies the address or ID of the mobile terminal TA-6 for which the extension connection is to be established based on the destination terminal information included in the extension connection request signal in step S109, and uses this. The call signal is transmitted to the mobile terminal TA-6 (C16). As a result, the ringtone of the mobile terminal TA-6 is played (step S110), and by tapping the icon IC4 displayed on the mobile terminal TA-6, an extension connection can be established between the mobile terminals TA-7 and TA-6. Established, the user 0007 and the user 0006 can make an extension call via the TA sound input / output unit 34. After the call is completed, the line is cut off by tapping the icon IC5. Further, by tapping the icon IC3 of the menu bar area 611 displayed on the TA display unit 36, it is possible to return to the screen (FIG. 5A) based on the watching application.

Further, in step S111 of FIG. 3, when the user 0007 performs a predetermined logout operation on the mobile terminal TA-7, a logout request signal is transmitted from the mobile terminal TA-7 to the management server SV (C17), and in response to this. The management server SV performs logout processing and transmits a logout response signal to the mobile terminal TA-7.

In parallel with this, in step S112, the management server SV creates update data of the telephone directory data in response to the user 0007 logging out from the mobile terminal TA-7. More specifically, the management server SV deletes and updates the combination of the logged-out mobile terminal TA-7 and the user 0007 from its own phonebook data, and updates the combination of the mobile terminal TA-7 and the user 0007 in the phonebook. Update information requesting deletion from the data is transmitted to all logged-in mobile terminals (C19). The mobile terminal that has received the update information updates by deleting the combination of the mobile terminal TA-7 and the user 0007 from the telephone directory data stored in its own TA storage unit 32 (step S113). For example, the telephone directory data updated by the mobile terminal TA-6 is as shown in FIG. 9 (b), that is, the user name of the mobile terminal TA-7 is obtained with respect to the telephone directory data shown in FIG. 9 (a). Is blank. That is, the combination of the mobile terminal TA-7 and the user name 0007 is invalidated in the telephone directory data.

At this time, when the mobile terminal TA-6 shifts to the extension call mode, as shown in FIG. 7B, the main area 612 is currently logged in except for oneself based on the updated telephone directory data. The user names "0001", "0002", "0003", and "0005" are displayed, from which the other party who can make an extension call can be specified. In this way, the phonebook data of all logged-in mobile terminals is updated when any user logs in or out, so always refer to the latest phonebook data and extend appropriately. A connection can be established.
