A collective entrance door 27 is connected to the collective entrance machine 2.

  The input unit 21 is operated for a visitor or the like to input room number information. The room number information includes the number of the visited room. In this example, the room number information is input by operating a button on the operation panel. It can also be performed by operating buttons on the touch panel in the entrance machine display unit 25. The call button 22 is a button used by a visitor or the like to call a visited place, and is operated after the room number information is input.

  The authentication unit 23 authenticates the resident identification information by short-range wireless communication. The resident can unlock the collective entrance door 27 by touching the authentication unit 23 with an NFC card built in the portable terminal 5. The camera 24 is a camera for imaging visitors and the like. The entrance machine display unit 25 is configured by, for example, a liquid crystal display on which a room number input by the input unit 21 or a visitor captured by the camera 24 is displayed. The call part is composed of a microphone 26a and a speaker 26b for making calls with residents, managers, and the like.

  The collective entrance machine 2 controls the operation of the collective entrance door 27 based on a signal transmitted from the server 3. The collective entrance door 27 is provided at the collective entrance of the collective housing, and is formed of an automatic door having a function of restricting access to the building A.

  The server 3 has a function of controlling the collective entrance machine 2, the WiFi-AP 4, the management base unit 6, and the like. The server 3 is connected to the collective entrance 2 and each WiFi-AP 4 via a hub (for example, Power over Ethernet-HUB) 11 so as to be communicable. The server 3 can be connected to the Internet (general-purpose network) N via a hub 11 and a router (for example, a Broad Band router) 12. The server 3 is connected via the Internet N so as to be communicable with the management base unit 6 of the centralized management room K. The server 3 and the hub 11 are connected to an uninterruptible power supply 13 that is supplied when power supply from the outside is interrupted.

  The WiFi-AP 4 is a radio wave relay that connects the server 3 and the mobile terminal 5 wirelessly. In order to enable wireless communication in the building A, the WiFi-AP 4 is installed, for example, in a passage on each floor with a predetermined interval. The WiFi-AP 4 forms a wireless communication area S that covers the entire area of the building A, for example.

  The portable terminal 5 is a terminal capable of information communication such as a smartphone, a tablet, and a mobile phone owned by a resident of the building A. The portable terminal 5 can communicate with the server 3 via the WiFi-AP 4 in the wireless communication area S. In the portable terminal 5 used in this example, a dedicated application for responding to a call from the collective entrance 2 is installed in advance. The portable terminal 5 includes a speaker 51, a terminal display unit 52, and a microphone 53.

  The speaker 51 and the terminal display unit 52 constitute the notification unit 50 of the mobile terminal 5.

The terminal display unit 52 is configured by, for example, a touch panel display, and displays information received from the server 3 as, for example, a message, an image, or the like. The microphone 53 forms a call part of the portable terminal 5 together with the speaker 51.

  The management base unit 6 is installed in a centralized management room K provided outside the building A, for example. The management base unit 6 can transmit management information related to the building A to the server 3 via the Internet N. In addition to the building A, a building B to a building D having the same configuration as the building A are connected to the management base unit 6 via the Internet N. When the management room is provided in the own building A, management such as information provision only in the building A may be performed by the management base unit 6 installed in the management room.

Next, functions of the server 3 will be described.
As shown in FIG. 2, the server 3 includes a server CPU 31, a storage unit 32, and a server interface circuit (hereinafter referred to as server I / F) 36.

  The storage unit 32 stores a terminal identification table 34 having room number information 33A and terminal identification information 33B, notification information 35, and the like. The room number information 33A is information that identifies the room number of each room in the building A. The terminal specifying information 33B is information that specifies the mobile terminal 5 that communicates with the server 3, and is information that specifies, for example, the mobile terminal 5 owned (used) by a resident in each room. The notification information 35 is information notified to the resident, and includes, for example, the minutes of the meeting of the management association, communication items (cleaning date, construction date, etc.), emergency notification information, missed call information, and the like.

  The room number information 33A and the terminal identification information 33B are stored as a terminal identification table 34 associated with each other (see FIG. 4A). The terminal identification information 33B is information for identifying a portable terminal that a resident of each living room desires to register in advance. The resident can also register the terminal identification information 33B of the plurality of portable terminals 5 for the room number information 33A at home (see FIG. 4B).

  The server CPU 31 determines a signal (information) received from each device based on information stored in the storage unit 32, and performs control to transmit the signal (information) to a specific device. For example, the server CPU 31 performs control for identifying the signal received from the collective entrance 2 based on the terminal identification table 34 and identifying the terminal identification information 33B for the room number information 33A and transmitting the signal to the portable terminal 5.

  The server I / F 36 constitutes a communication unit for forming a signal transmission path with the collective entrance machine 2, the portable terminal 5, the management base unit 6, and the like. The server I / F 36 functions as a receiving unit for receiving a signal transmitted from each device or as a transmitting unit for transmitting a signal to each device.

  Next, with reference to FIGS. 3-7, the example of an operation pattern of the intercom system 1 for apartment houses is demonstrated. In this example, it is assumed that the apartment house is an apartment (building A) having a configuration as shown in FIG.

<Operation pattern 1>
(basic setting)
1) Visitor F visits a resident who lives in building A.
2) Family structure of the resident who visited: Living with four mothers, father, eldest daughter, and second daughter (not shown in FIG. 3)
3) Resident's room: Room 103 of building A 4) As shown in the terminal identification table 34a in FIG. 4A, room number information 33A and terminal identification information 33B are associated with each other.

  The visitor F inputs the room number information (room 103) 33A of the visited place from the input unit 21 of the collective entrance 2 and presses the call button 22 to call a resident in the room 103. When the collective entrance 2 is operated, the camera 24 is activated to capture the image of the visitor F. When the call button 22 is pressed, the collective entrance 2 transmits a call signal including the room number information 33A to the server 3 via the hub 11.

  The call signal is received by the server I / F 36 of the server 3. The server CPU (an example of an assigning unit) 31 detects the room number information “room 103” included in the call signal, and “room 103” based on the detected room number information “room 103” and the terminal identification table 34a. The terminal specifying information 33B associated with is determined. In this example, as shown in FIG. 4A, “34567” is determined as the terminal specifying information 33B for specifying the portable terminal 5 of the occupant in room 103. The server CPU 31 adds the determined terminal identification information “34567” to the call signal received from the collective entrance 2. The call signal to which the terminal identification information “34567” is attached is transmitted from the server I / F 36 of the server 3.

  Subsequently, the call signal to which the terminal identification information “34567” is attached is transferred to each WiFi-AP 4 via the hub 11 and further transmitted from the respective WiFi-AP 4 into the building A by radio. As a result, the mobile terminal 5 in the wireless communication area S formed by the WiFi-AP 4 can receive the call signal to which the terminal identification information “34567” is added. In this example, as shown in FIG. 3, the terminal identification information “34567” is given to the portable terminal 5A in the lounge, the portable terminal 5B in the room 103, and the portable terminal 5C in the room 302. Receiving call signals respectively.

  Each of the received mobile terminals 5A, 5B, and 5C determines whether or not the terminal specifying information “34567” matches the information specifying the own mobile terminal based on the dedicated application installed in the mobile terminal. The mobile terminal 5 that has been determined to match the information specifying the mobile terminal notifies the resident through the notification unit 50 that the visitor F is calling from the collective entrance.

  In this example, it is determined that the mobile terminal 5B in the room 103, which is the visit destination of the visitor F, matches the information specifying the mobile terminal. For example, as illustrated in FIG. 5, the mobile terminal 5 </ b> B outputs a reception sound 56 for notifying that information has been received from the speaker 51. At this time, the message 54 “There is a visitor” and the image 55 of the visitor F captured by the camera 24 of the collective entrance 2 may be displayed on the terminal display unit 52. The mobile terminal 5B also has a response button 57 for responding to the call of the visitor F and an unlock button (unlocking) that can issue a command signal (unlock signal) for unlocking the collective entrance door 27. An example of the command unit) 58 is displayed on the terminal display unit 52.

  On the other hand, other portable terminals (in this example, the portable terminals 5A and 5C) that are determined not to be information identifying the own portable terminal end the process for the call signal from the visitor F. Thereby, the communication path of this system is formed only with respect to the portable terminal 5B, and only the portable terminal 5B becomes ready to respond to the calling signal from the collective entrance 2.

  When the response button 57 of the portable terminal 5B is pressed, a response signal is transmitted from the portable terminal 5B to the server 3 via the WiFi-AP 4. As a result, the server 3 forms a communication path via the server 3 between the portable terminal 5B and the collective entrance 2 to enable a call between the visitor F and the occupant in the 103rd room. When the unlock button 58 of the mobile terminal 5B is pressed, an unlock signal is transmitted from the mobile terminal 5B to the server 3 via the WiFi-AP 4. The unlock signal is transmitted from the server 3 to the collective entrance machine 2, and the collective entrance door 27 is unlocked.

  3 shows the case where the portable terminal 5B is in the No. 103 room, but the present invention is not limited to this, and it may be located anywhere in the wireless communication area S. For example, if the occupant in room 103 carries the portable terminal 5B and is somewhere in the building A, the calling signal from the collective entrance 2 is transferred.

  According to the multi-dwelling intercom system 1 of the present embodiment described above, a plurality of WiFis capable of forming a wireless communication area S covering the entire area in the building A, instead of the dedicated intercom line used conventionally. -AP 4 and server 3 connected to the Internet N are installed in building A. For this reason, it is not necessary to lay a dedicated communication line in the building A, and construction costs can be reduced.

  Also, in place of the interphone-only room master unit installed in each room, a dedicated application having a function capable of responding to a call signal is installed in the mobile terminal 5, thereby realizing a communication path in the system. Has been. For this reason, it is not necessary to install the room master in each room, and the equipment cost can be reduced.

  Even if a management room is not provided in the building A, the management service can be provided remotely via the Internet N. Further, a plurality of buildings (building A to building D) having different locations can be managed from a single location by using a single management master unit 6.

  Thereby, the cost for introducing the intercom system in the building A can be reduced. Moreover, since the wiring used for the connection between apparatuses decreases, the introduction work period can be shortened.

<Operation pattern 2>
(basic setting)
1) to 3) are the same as the conditions of the operation pattern 1 4) As shown in the terminal identification table 34b of FIG. 4B, there are a plurality (three in this example) for the room number information 33A of the room 103. Terminal identification information 33B is associated.

  In the same manner as in the operation pattern 1, the server CPU 31 detects the room number information “room 103” included in the call signal, and “103” based on the detected room number information “room 103” and the terminal identification table 34b. The terminal identification information 33B associated with the “room” is determined. In this example, as shown in FIG. 4B, three pieces of terminal identification information “34561”, “34562”, “34563” registered as terminal identification information 33B for identifying the portable terminal 5 of the occupant of room 103 are identified. Is determined. First, the server CPU 31 obtains terminal specifying information “34561” for specifying the mother mobile terminal 5 registered as the terminal specifying information 33B having the highest priority among the determined three terminal specifying information 33B. 2 is added to the paging signal received from 2.

  The call signal to which the terminal identification information “34561” is assigned is transferred from the server 3 to each WiFi-AP 4 and transmitted from the WiFi-AP 4 to the building A by radio. When the mother mobile terminal 5 receives the call signal to which the terminal identification information “34561” is added, the mother mobile terminal 5 determines that “34561” matches the information identifying the own mobile terminal, and calls the visitor F. The notification unit 50 notifies that there is.

  When no response signal or unlock signal is returned from the mother mobile terminal 5 in response to the calling signal, the server CPU 31 specifies the father mobile terminal 5 registered as the terminal specifying information 33B having the next highest priority. The terminal identification information “34562” is added to the call signal and transferred. The call signal to which the terminal identification information “34562” is attached is transmitted from the respective WiFi-APs 4 into the building A by radio. The father's mobile terminal 5 receives the call signal to which the terminal identification information “34562” is added, and notifies that there is a call from the visitor F through the notification unit 50.

  Similarly, when there is no reply from the father's mobile terminal 5, the server 3 uses the terminal specifying information “34563” for specifying the eldest mobile terminal 5 registered as the terminal specifying information 33B having the next highest priority. The call signal is added and transferred. The eldest daughter's mobile terminal 5 receives the call signal with the terminal identification information “34563”, and notifies the notification unit 50 that there is a call from the visitor F.

  For example, if the server CPU 31 does not reply for 15 seconds after transferring the call signal with the mother's terminal identification information “34561”, the server CPU 31 sends the call signal with the next father's terminal identification information “34562”. Forward. The server CPU 31 performs the same control when transferring the calling signal to which the eldest daughter's terminal identification information “34563” is assigned. When transferring the call signal to which the next terminal identification information 33B is assigned, the transfer of the previous call signal may be stopped, or a plurality of call signals may be transferred without being stopped. You may make it do.

  According to the collective housing intercom system 1 of such a form, a plurality of portable terminals 5 owned by the family members in each room can be registered as portable terminals to which calls from the collective entrance 2 are transmitted. For this reason, when three mobile terminals 5 are registered as in room 103, for example, even when the mother is out with her mobile terminal 5, the visitor can use the mobile terminal of the father or eldest daughter. Can answer F calls. In addition, since the priority order at which the call is transmitted can be arbitrarily set on the room side, for example, the mother's mobile terminal 5 that has a relatively long time in the wireless communication area S is registered so as to have the highest priority. By doing so, it is possible to more reliably respond to a call from the visitor F or the like. In this way, by adopting a configuration in which a plurality of mobile terminals 5 can respond to a call by one collective entrance 2, the reception sound of the mobile terminal 5 can be output in a sliding manner, depending on the situation. A more appropriate person can answer the call.

<Operation pattern 3>
(basic setting)
1) Resident G, who lives alone in Room 201, has returned from the office.
2) Residents have missed call information.
3) As shown in the terminal identification table 34a in FIG. 4A, room number information 33A and terminal identification information 33B are associated with each other.

  When the resident G who returns home touches the portable terminal 5 on the authentication unit 23 of the collective entrance 2, portable terminal information of the portable terminal is read. The collective entrance machine 2 determines whether the read mobile terminal information matches any of the resident's mobile terminal information, and when determining that they match, unlocks the collective entrance door 27. The collective entrance 2 detects resident information (for example, the room number of the resident G) included in the read mobile terminal information, and transmits a return signal to which the resident information is added to the server 3.

  The server CPU 31 specifies the resident G and the room number (room 201) based on the resident information given to the return signal, and whether the missed call information has arrived at the resident G, notification information in the storage unit 32 Determination is made with reference to FIG. The missed call information includes, for example, information notifying that there was a visitor when the resident is absent, and information received from the management base unit 6 when absent. When the missed call information has arrived, the server CPU 31 is associated with the room number information 33A of the resident G based on the room number of the resident G given to the return signal and the terminal identification table 34a. The terminal identification information 33B is determined. In this example, as shown in FIG. 4A, “45678” is determined as the terminal specifying information 33B for specifying the portable terminal 5 of the resident G in the 201st room.

  The server CPU 31 adds the determined terminal identification information “45678” to the missed call information and transmits it to each WiFi-AP 4. The mobile terminal 5 of the resident G detects the terminal specifying information “45678” for specifying its own mobile terminal, and, for example, as shown in FIG. Output. In addition, a message 64 “There is a visitor in the absence” and an image 65 of the visitor H captured by the camera 24 are displayed on the terminal display unit 52.

  According to the intercom system 1 for collective housing of such a form, even if there is a visitor or a message from a manager while the resident G is out, the portable terminal 5 It is convenient because it can know the missed call information via. In addition, the resident G can conveniently check the missed call information before returning to the room (Room 201).

In addition, for example, the system using the mobile terminal 5 can also be applied to the case where the manager of the building A notifies the resident of the information.
Specifically, information (communication items) communicated by the administrator is transmitted from the management master unit 6 of the centralized management room K to the server 3 via the Internet N. The contact item is given room number information 33A of the resident who is the subject of communication. The communication item to which the room number information 33 </ b> A is assigned is stored as notification information 35 in the storage unit 32 of the server 3. The server CPU 31 determines the terminal identification information 33B associated with the room number information 33A of the resident who is the contact object, based on the room number information 33A assigned to the communication item and the terminal identification table 34a. The server CPU 31 assigns the determined terminal identification information 33B to the communication item and transmits it to each WiFi-AP 4.

  The mobile terminal 5 in the wireless communication area S detects the terminal specifying information 33B for specifying its own mobile terminal, and displays a communication item 74 on the display unit 52 as shown in FIG. Received sound 76 is output from speaker 51. As a result, notification information and the like to the resident can be notified via the portable terminal 5 possessed by the resident, so that it is not necessary to stick a bulletin board or the like in the building A, and the management cost can be reduced.

  In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. In addition, the material, shape, dimension, numerical value, form, number, location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.
