Description

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

  In Japan, the aging population is declining rapidly due to the increase in the average life expectancy of the people and the decline in the birth rate. Along with this, hospitals and welfare facilities for the elderly that accommodate those who need care (care recipients) are increasing, but the labor of nurses and caregivers is chronically sufficient due to harsh working conditions. This is a serious situation. Especially at night and so on, a small number of people need to watch over a large number of care recipients, which increases the burden on the caregiver and the like, which causes further labor shortages.

  In order to reduce the burden on such caregivers and the like, there is a need for a technology that supports care work. For example, in order to cause a machine to perform a part of work such as a caregiver, various techniques for monitoring a person who needs care have been developed.

  Patent Document 1 discloses that when an abnormality detection device detects an abnormality of a monitoring target such as a care recipient, the monitoring target image data is captured and transmitted to an external terminal via a network or the like. A technique for remotely monitoring the current status of a monitoring target by transmitting a message is disclosed.

JP 2005-253025 A Japanese Patent No. 3155908

  By the way, in recent years, the performance of mobile terminals called so-called smart phones has been improved, and even though it has the performance of a PC, it has been marketed that is small enough to be carried in a pocket of a caregiver or the like. Yes. Therefore, caregivers or the like travel around the facility with the portable terminal and actually perform necessary care for the care recipient, while applying another care recipient, for example, the technology of Patent Document 1 It can be monitored remotely via the portable terminal. As a result, a large number of care recipients can be cared for by a small number of caregivers, and the burden on the caregivers can be reduced at the same time. Such remote monitoring can be realized by a monitoring system including a camera that acquires image data of a care recipient, a transmission device that transmits image data from the camera, and a mobile terminal in which a monitoring application is installed.

  On the other hand, as shown in Patent Document 2, a technology is known in which a private branch exchange (hereinafter referred to as PBX) connected to an external public line is linked to a computer. Some PBXs have a function of establishing an extension connection between portable terminals. If the technology of Patent Document 2 is used, it is possible to provide a high-level service by linking a PBX provided in a facility with a mobile terminal.

  However, a certain type of PBX uses a telephone directory stored in each portable terminal in order to specify the other party when establishing an extension connection. That is, when there is an extension connection request from a portable terminal, the connection is made to the partner terminal recorded in the telephone book of the portable terminal. On the other hand, since a caregiver or the like works in a shift system in a normal care facility or the like, it is expected that a plurality of caregivers use a single mobile terminal jointly. In such a case, changing the user of the portable terminal may cause confusion because it is not possible to converse with the other party who wants to make an extension call. Such a problem may occur even when monitoring is performed with a fixed terminal as well as a portable terminal.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a communication system capable of easily making an extension call to a desired destination even when a caregiver or the like shares a terminal.

In order to achieve at least one of the objects described above, a communication system reflecting one aspect of the present invention is provided.

Each terminal is capable of storing phone book data recorded in association with counterpart terminal information and counterpart user information corresponding to other terminals in the storage unit. When an operation for making an extension call is performed by designating destination user information, the terminal sends an extension including the destination terminal information of the phone book data corresponding to the designated destination user information to the PBX. A connection request can be sent,
When there is an extension connection request from one of the terminals, the PBX establishes an extension connection to the terminal corresponding to the counterpart terminal information,
When the terminal transmits a login request signal including user information to the central server, the central server transmits the login information signal and the user information included in the login request signal. Update information including a combination with the terminal is transmitted to all the terminals logged in to the central server, and the terminal stores the phone book data stored in the storage unit based on the transmitted update information. Is to be updated.

  Such a portable 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 care support system in the embodiment will be described. Since a general-purpose portable terminal using an OS such as “Android (registered trademark)” can execute a plurality of installed applications, it can be used in the 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 destination terminal information and destination user information are associated with each other for extension connection. By using this function, it is possible to make an extension call between portable terminals via the PBX. That is, an extension connection with a partner mobile terminal can be established by making an extension connection request including the partner terminal information from any one of the mobile terminals.

  Here, when there is an extension connection request including the partner terminal information, the PBX establishes the extension connection with the mobile terminal specified based on the partner terminal information. On the other hand, since a caregiver or the like works in a shift system in a normal care facility or the like, a plurality of caregivers may use a single mobile terminal jointly. Therefore, even if the extension connection is established with the portable terminal specified based on the destination terminal information, it is not necessarily the other party that made the 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 partner without taking time and effort.

  Here, the entire 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 who have started work (user 0006) turns on the main switch of the portable terminal TA that he / she has. Then, a login screen as shown in FIG. 4 to be described later is displayed. In a portable terminal using an OS such as “Android (registered trademark)”, a standard login screen is displayed. Here, the login screen as shown in FIG. 4 is customized to be displayed first. .

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

  Here, the portable terminals TA-1 to TA-3 and TA-5 (not shown in FIG. 3) and TA-7 have already logged in, and watch over the subject Ob as shown in step S101 in FIG. Assume that the user 0006 who is a caregiver newly logs in from the mobile terminal TA-6 from the monitored state.

  Before the user 0006 logs in, the phone book data shown in FIG. 8A is stored in the TA storage unit 32 of the portable terminal TA-7. In the phone book data shown in FIG. 8A, the user is not logged in from the portable terminals TA-4 and TA-6, and the user is blank, and the portable terminal TA-7 means “OWN”. It is recorded. In this state, when the portable 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 phone book data. The user names “0001”, “0002”, “0003”, and “0005”, which are currently logged in except for myself, are displayed, and from here, it is possible to designate a partner that can make an extension call. The management server SV also stores phone book data (basic phone book data) that associates all mobile terminals that are currently logged in with user names.

  In step S102 of FIG. 3, the user 0006 performs a login operation from the portable terminal TA-6, whereby the watching system is activated on the portable terminal TA-6. More specifically, on the login screen shown in FIG. 4 of the portable terminal TA-6, the user taps the triangle mark MK1 at the right end of the input column CL1 of “user name” to display a plurality of options. Then, tap and select your user name “User 0006” (user ID: the name of your caregiver), and use the numeric key NK displayed below it in the “Pass” entry field CL2. Enter a 4-digit number. Thereafter, the user taps the button B11 to complete the login operation. The path input may be omitted.

  As a result of the login operation in step S102 in FIG. 3, a login request signal including a user name (0006) as user information (user ID) and the terminal ID of the portable terminal TA-6 is sent from the portable terminal TA-6 to the management server. It is transmitted to the SV (C11). The management server SV that has received the login request signal refers to the database stored in the built-in memory, confirms that the user name and path match, performs login authentication (step S103), and indicates that login authentication has been successful. A response signal is transmitted to portable terminal TA-6 (C12). In the portable terminal TA-6 that has received such a response signal, the watching application is activated to support watching of the subject Ob as described later (step S104). Although not shown, if the user name and the path do not match, the management server SV transmits a failure signal to the portable terminal TA-6 and prompts another login operation.

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

  When the portable terminal TA-6 receives a copy (update information) of the basic telephone directory data, it stores it in its own TA storage unit 32 in step S106 (if the previous telephone directory data remains). Replaces) changes the user name of the portable terminal TA-6 to “OWN” meaning itself. The updated phone book data is as shown in FIG. 9A, that is, the portable terminal TA-4 is not logged in, and the portable 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 itself, based on the updated phone book data. The user names “0001”, “0002”, “0003”, “0005”, and “0007” are displayed, and from here, it is possible to designate a partner who can make an extension call.

  In parallel with the above, the management server SV transmits update information including the combination of the newly logged-in portable terminal TA-6 and the user 0006 to all the logged-in portable terminals other than the portable terminal TA-6 ( C14). The mobile terminal that has received the update information performs an update by additionally recording this combination in the phone book data stored in its own TA storage unit 32 (step S107). Note that the updated copy of the phone book data may be transmitted to all the mobile terminals that are logged in and replaced with the stored ones. Thus, for example, the phone book data updated in the portable terminal TA-7 is as shown in FIG. 8B, that is, the phone book data shown in FIG. Correspondingly, a user name 0006 is added. That is, the combination of the portable terminal TA-6 and the user name 0006 is effective in the phone book data.

  Here, support for monitoring (watching) the target person Ob by executing the watch application in step S104 (also in step S101) will be described. When the watching application is activated, the portable terminal TA-6 causes the TA processing unit 312 to display a standby screen waiting for a communication signal addressed to itself on the TA display unit 36. For example, as shown in FIG. 5A, the standby screen includes a menu bar area 611 for displaying a menu bar, a message indicating that the standby is in progress (for example, “no unsupported notification”), date and current A standby main area 612 for displaying a user name 63 (0006) logged in to the portable terminal TA-6 at time 612; While displaying such a standby screen, the portable 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 illustration is omitted, the sensor box SB that monitors each subject Ob obtains image data of the subject 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 indicates what kind of event has occurred. The notification information including the event information to be shown and the communication address is 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 is the resident (here, Mr. B) based on the information of the sensor box SB included in the notification signal, Further, it is determined from the event information of the notification signal whether the notification event corresponds to the resident (Mr. B) (in this case, falls or falls: a specific state). 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 a notification event (in the case of Mr. B, wakes up or leaves), it is determined 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) is selected as the portable 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 portable terminal.

  When such a notification signal is transmitted from the management server SV, the portable terminal TA-6 causes the TA processing unit 312 to switch the screen display of the TA display unit 36 to, for example, that shown in FIG. In the example shown in FIG. 5B, in the main area 612, the name of the room where the event occurred (RM-2 room), the name of the resident in the room (B-like), and the icon IC1 indicating a fall or fall The time difference (0 minute) between the notification time and the current time is displayed. At the same time, buttons B1 (corresponding), B2 (speak), B3 (view stored video), and B4 (view live video) are displayed in the main area 612.

  Here, when the caregiver touches the button B3 or B4 (also referred to as a tap), the TA input unit 35 of the portable terminal TA-6 reacts, and the TA control unit 311 determines that an 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 transmitted directly 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 for requesting a stored image is output from the portable terminal TA-6. Therefore, the sensor box SB that has received the request via the management server SV requests a stored image. 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 for requesting a live image is output from the portable terminal TA-6, and the sensor box SB that has received the request via the management server SV requests the live image. Therefore, the live video imaged by the camera unit is encoded and transmitted from the sensor box SB to the management server SV via the network NW.

  The portable terminal TA-6 that has received the image data switches the screen display of the TA display unit 36 to, for example, the one shown in FIG. In the example shown in FIG. 5C in which the stored video is requested, the image (video) IMG of Mr. B before and after falling down in the RM-2 room is displayed in the main area 612. The person can immediately determine whether or not the state should be dealt with. In addition, if it cannot be determined by just looking at the image IMG, the caregiver can touch the button B2 so that Mr. B and the caregiver can talk directly via the sound input / output unit (not shown) of the sensor box SB. Therefore, the situation can be judged accurately.

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

  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 if an extension call can be made between mobile terminals using PBX. Hereinafter, extension connection using PBX from the portable terminal TA-7 used by the user 0007 to the portable terminal TA-6 used by the user 0006 will be described.

  When the caregiver (user 0007) taps the icon IC2 (see FIG. 5) in the menu bar area 611 displayed on the TA display unit 36 of the portable terminal TA-7 used by the caregiver, 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 phone book data, the name of the currently logged-in user “0001” except for oneself is displayed in the main area 612. , “0002”, “0003”, “0005”, and “0006” are displayed. The user 0007 can designate a partner with whom an extension call is desired. Since a user who is not logged in at this time cannot be specified, the user can make an extension call without confirming whether the other party has logged in or not. Obviously, when only one user is logged in, no user name is displayed on the screen, and it is understood that an extension call cannot be made.

  When an extension call is to be made to the user 0006, the user 0006 on the display screen is specified by tapping, and the displayed icon IC4 is further tapped (step S108 in FIG. 3). At this time, the terminal TA-7 refers to its own phone book data, selects destination terminal information (TA-6) associated with the designated user 0006, and sends the destination terminal to the PBX. An extension connection request signal including information (TA-6) is transmitted (C15). In step S109, the PBX that has received this specifies the address or ID of the portable terminal TA-6 that wants to establish the extension connection based on the counterpart terminal information included in the extension connection request signal, and uses this. A call signal is transmitted to the portable terminal TA-6 (C16). Thereby, the ring tone of the portable terminal TA-6 becomes (step S110), and the extension connection is established between the portable terminals TA-7 and TA-6 by tapping the icon IC4 displayed on the portable terminal TA-6. Thus, the user 0007 and the user 0006 can make an extension call via the TA sound input / output unit 34. After the call is finished, the line blocking operation is performed by tapping the icon IC5. Further, by tapping the icon IC3 in the menu bar area 611 displayed on the TA display unit 36, it is possible to return to the screen based on the watching application (FIG. 5A).

  Furthermore, when the user 0007 performs a predetermined logout operation at the portable terminal TA-7 in step S111 in FIG. 3, a logout request signal is transmitted from the portable terminal TA-7 to the management server SV (C17). Then, the management server SV performs a logout process and transmits a logout response signal to the portable 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 portable terminal TA-7. More specifically, the management server SV deletes and updates the combination of the logged-out portable terminal TA-7 and the user 0007 from its own phone book data, and changes the combination of the portable terminal TA-7 and the user 0007 to the phone book. Update information required to be deleted from the data is transmitted to all the mobile terminals that have logged in (C19). The mobile terminal that has received the update information performs update by deleting the combination of the mobile terminal TA-7 and the user 0007 from the phone book data stored in its own TA storage unit 32 (step S113). For example, the phone book data updated in the mobile terminal TA-6 is as shown in FIG. 9B, that is, the user name of the mobile terminal TA-7 with respect to the phone book data shown in FIG. 9A. Is blank. That is, the combination of the portable terminal TA-7 and the user name 0007 becomes invalid in the phone book 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 itself based on the updated phone book data. User names “0001”, “0002”, “0003”, and “0005” are displayed, and from here, it is possible to designate a partner that can make an extension call. In this way, when any user logs in or out, the phone book data of all the mobile terminals that are logged in is updated. A connection can be established.
