However, in the technologies described in Patent Documents 1, 2, and 3 described above, when the shared interphone and the door-to-door interphone are disconnected, it is not possible to make a call between them. In other words, if you want to make a call, you have to wait until the common intercom and the door-to-door intercom are restored by repairs.
The present invention has been made in view of the above points, and provides a collective housing intercom system capable of making a call without waiting for recovery even if the shared intercom and the door-to-door intercom are disconnected. Objective.

(1) Means for solving the problem (hereinafter, simply referred to as “solution means”) 1 includes a common interphone installed in a common space of an apartment house, and a plurality of individual doors installed in each house of the apartment house. There is a local communication path between the intercom, a local communication path that is installed in the apartment house and connects the common intercom and the multiple door-to-door intercoms, and a single intercom selected from the multiple door-to-door intercoms and the common intercom. An intercom system for apartment houses having a control unit that performs control so that a call can be made via
Storage means for storing a telephone number corresponding to an identification number assigned to each door-to-door interphone, and disconnection between one door-to-door interphone selected from a plurality of door-to-door intercoms based on the input of the identification number and the shared intercom If the disconnection detecting means detects whether or not the disconnection detecting means detects a disconnection, it switches from the local communication path to an external communication path other than the local communication path, and refers to the storage means to obtain a telephone number corresponding to the identification number. The gist of the invention is to have conversion call means for converting and calling.

  According to the solution 1, when the common intercom used mainly by the visitor and the door-to-door intercom used mainly by the resident are not connected, the conversion calling means is used as a local communication path (for example, an IP communication path). After switching to an off-premise communication path (for example, a telephone line), the telephone number is converted into a telephone number corresponding to an identification number (for example, a room number) to make a call. Therefore, it is possible to make a call without waiting for recovery, and the visitor or the like does not need to know the telephone number.

(2) The solution means 2 is the intercom system for collective housing described in the solution means 1, and the disconnection detecting means is applied to one door intercom selected from among the plurality of door intercoms based on the input of the identification number. On the other hand, the gist is to transmit a detection signal and detect a disconnection when a predetermined condition is satisfied when there is no response to the detection signal.

According to the solution means 2, if there is no response to the detection signal transmitted by the discontinuity detection means, it is detected that a discontinuity has occurred between the shared intercom and the door-to-door intercom under a predetermined condition. As described above, since it is accurately determined whether or not the call is disconnected, a call can be made by the conversion calling means, and a call can be made without waiting for recovery.
The predetermined conditions can be set as appropriate. For example, there is no response even after a predetermined period has elapsed since the detection signal is transmitted, or the detection signal is transmitted a predetermined number of times and responded once. Conditions such as the absence of such are applicable.

(3) Solution means 3 is an intercom system for collective housing as described in Solution means 1 or 2, and is a setting means for inputting a telephone number corresponding to an identification number assigned to each door interphone and storing it in the storage means It is summarized as having.
The storage means may be provided in one or more interphones among the common interphone and the door-to-door interphones, or in a computer other than the interphone (for example, a server).

According to the solution means 3, the telephone number for each door intercom can be stored (set) in the storage means by the setting means. Not only when a new resident memorizes a new house due to a new construction, moving, or the like, but it is possible to easily memorize even when a telephone number such as a mobile phone or an IP phone is changed from a fixed phone. For example, when the telephone number of a mobile phone is stored, it is possible to respond to a visitor who has visited when he / she is absent.
The setting unit may be provided in one or more interphones among the common interphone and the door-to-door interphones, or in a computer (for example, a server) other than the interphones.

(4) The solving means 4 is the collective housing intercom system according to any one of the solving means 1 to 3, wherein the common interphone has a waiting time until the calling by the conversion calling means is started. The gist is to have a time notification means for notification.

  According to the solution means 4, since the time notification means informs the waiting time until the call is started, not only the disconnection state is known, but also the misunderstanding that the resident of the dwelling unit to be called is absent. Can be prevented.

(5) Solving means 5 is the intercom system for collective housing as described in any one of solving means 1 to 4, and when the discontinuity detecting means detects discontinuity in the door-to-door interphone, discontinuity is notified. The gist is to have a notification means.

  According to the solving means 5, the non-notification notifying means notifies the disconnection state, so that a resident or the like of a dwelling unit with a door-to-door intercom can recognize the possibility of calling the telephone number stored in the storage means. Therefore, a resident or the like can prepare for a call to the telephone.

  According to the present invention, even if the shared interphone and the door-to-door interphone are disconnected, it is possible to make a call without waiting for recovery.

  The best mode for carrying out the present invention will be described with reference to FIGS.

  In FIG. 1, the structural example of the intercom system for apartment houses is represented with a schematic diagram. The collective housing intercom system has a common intercom 10, an IP communication path 20, a plurality of door-to-door interphones 41, 42,..., 61, 62,. In this example, the door-to-door interphones 41, 42,... Correspond to dwelling units on a predetermined floor (for example, the second floor), the door-to-door interphones 61, 62,... Correspond to dwelling units on another floor (for example, the second floor), etc. , Corresponding to each floor of the apartment house. With this correspondence, the repeater 31 is interposed between the common interphone 10 and the door-to-door interphones 41, 42,..., And the repeater 32 is interposed between the common intercom 10 and the door-to-door interphones 61, 62,. As in the above, a repeater is provided for each floor of the apartment house.

  The common interphone 10 is installed in a common space (for example, entrance hall) of an apartment house, and is a device mainly used by visitors. The shared interphone 10 includes, for example, a camera 11, a display 12, a control unit 13, a speaker 14, a microphone 15, an input key 16, a call button 17, and the like. For example, a CCD camera or the like is used as the camera 11 and images visitors and the like. For example, a liquid crystal display is used as the display 12 and displays, for example, information input by the input key 16 and other information. The control unit 13 is in charge of overall control of the shared interphone 10, for example, one door interphone selected from the plurality of door interphones 41, 42,..., 61, 62,. Is controlled so as to be able to make a call via the IP communication path 20. The speaker 14 and the microphone 15 are used when making a call or the like with a door-to-door intercom. The input key 16 is composed of a numeric keypad and the like, for example, for inputting a room number (corresponding to an identification number) of a dwelling unit to be called. The call button 17 is used when calling one door-to-door interphone selected by the input of the input key 16 (that is, making a ringing tone).

  The plurality of door-to-door interphones 41, 42,..., 61, 62,... Are devices that are installed on each door of the apartment house and are mainly used by residents. Since the plurality of door intercoms 41, 42,..., 61, 62,... Have substantially the same configuration, the door intercom 41 will be described as a representative unless otherwise specified. The door-to-door interphone 41 includes a display a, a speaker b, a microphone c, an input key d, and the like. For example, a liquid crystal display is used as the display device a, and displays, for example, video and images captured by the camera 11 and other information. The speaker b and the microphone c are used when making a call or the like with the shared interphone 10. The input key d is composed of a numeric keypad as in the case of the input key 16, and is used, for example, for storing the telephone number of the telephone 51 installed in the dwelling unit in the common interphone 10.

  Next, the function of the common intercom 10 will be described with reference to FIG. In this example, the common interphone 10 is provided with functions such as the disconnection detecting means 1, the storage means 2, the conversion calling means 3, the setting means 4, and the time notification means 5. Some or all of these means are part of the functions realized in the control unit 13. If the control unit 13 does not realize the conversion, the shared interphone 10 may be provided with, for example, a conversion terminal having equivalent functions for the conversion call means 3.

  The disconnection detecting means 1 detects whether or not there is a disconnection between the one door-to-door interphone selected from the plurality of door-to-door intercoms and the shared interphone 10 based on the room number input by the input key 16. An example of the detection method will be described later (see FIG. 4). The storage means 2 is mainly a non-volatile recording medium (for example, a hard disk device or a flash memory), and all room numbers of the apartment house, telephone numbers corresponding to the room numbers assigned to each door intercom, and other information. Remember. The conversion calling unit 3 switches from the IP communication path 20 to the telephone line 80 when the disconnection detecting unit 1 detects a disconnection, converts the telephone number to the telephone number corresponding to the room number with reference to the storage unit 2, and makes a call. I do. The time notification means 5 notifies the waiting time until the call by the conversion call means 3 is started through the display 12, the speaker 14, and the like.

  The setting means 4 operates the input key 16 to input a telephone number corresponding to the room number assigned to each door intercom and store it in the storage means 2. 1, the telephone number of the telephone 51 corresponding to the door interphone 41, the telephone number of the telephone 52 corresponding to the door interphone 42,..., The telephone number of the telephone 71 corresponding to the door interphone 61, the door interphone 62 The telephone number of the corresponding telephone 72 is stored in correspondence with each room number. The storage by the setting means 4 can be performed at any time separately from the shared processing described later, but is preferably limited to a specific person (for example, a manager of an apartment house).

An example of processing executed by the shared intercom 10 in the collective housing intercom system configured as described above will be described with reference to FIGS. 3 and 4. FIG. 3 is a flowchart illustrating an example of the sharing process, and FIG. 4 is a flowchart illustrating an example of the disconnection detection process.
4 corresponds to the disconnection detecting unit 1, steps S14 to S18 correspond to the conversion calling unit 3, and step S22 corresponds to the time notification unit 5.

  In the shared processing of FIG. 3, after the room number is input by the input key 16, the call button 17 is pressed [Step S10], and the process waits until the input room number exists in the storage means 2 [Step S11]. If the input room number exists in the storage unit 2 (YES in step S11), the non-connection detection process for detecting whether or not the door-to-door interphone corresponding to the input room number and the common interphone 10 are not connected. [Step S12].

  Here, specific contents of the disconnection detection process will be described with reference to FIG. First, a detection signal (such as a packet) is transmitted to the door-to-door interphone corresponding to the input room number (the door-to-door interphone 41 in the example of FIG. 2) and waits for a response signal to be returned [step S20]. . When a response signal is received from the door-to-door interphone (YES in step S21), since the communication is possible, the disconnection detection process is returned without detecting the disconnection.

  When a response signal is not received from the door-to-door intercom (NO in step S21), information (for example, time, number of times, etc.) until a call is started is notified [step S22], and the above-described steps S20 to S22 until a predetermined condition is satisfied. Is repeated [step S23]. This predetermined condition can be set with arbitrary contents. For example, a predetermined time (for example, 10 seconds or 1 minute) has elapsed since the detection signal was transmitted in step S20, or the number of times the detection signal was transmitted is a predetermined number of times (for example, 5 or 10 times). This is true. If the predetermined condition is satisfied (YES in step S23), the disconnection is detected [step S24], and the disconnection detection process is returned.

  Returning to FIG. 3, when the disconnection of the IP communication path 20 is detected by executing the disconnection detection process (YES in step S <b> 13), a call is made through another communication path described later. On the other hand, when the IP communication path 20 is not disconnected and can be normally communicated (NO in step S13), the intercom process for performing a call between the common interphone 10 and the door-to-door intercom is performed [step S19], and the common process is performed. To return.

  Calls using other communication paths are performed as follows. That is, the telephone number corresponding to the room number is converted by referring to the storage means 2 [Step S14], and the communication path is switched from the IP communication path 20 to the telephone line 80 [Step S15]. Then, a call is made to the telephone number converted in step S14 [step S16], and telephone line processing for performing a telephone call is performed [step S17]. When the telephone line processing is completed due to line disconnection or the like, the telephone line 80 is returned to the IP communication path 20 in preparation for the next and subsequent processes [step S18], and the shared processing is returned. If necessary, in addition to the above-described processing, the disconnection state may be notified through the display 12 or the speaker 14 or the occurrence of the disconnection state may be notified to the management company of the apartment intercom system by an alarm or e-mail. desirable.

According to the embodiment described above, the following effects can be obtained.
(1) When the shared interphone 10 mainly used by visitors and the door-to-door interphones 41, 42,..., 61, 62,. After switching from the communication path 20 to the telephone line 80, the telephone number corresponding to the room number was converted to make a call (see FIG. 3). Therefore, it is possible to make a call without waiting for recovery, and the visitor or the like does not need to know the telephone number.

(2) If there is no response to the detection signal transmitted by the disconnection detecting means 1 of the shared interphone 10, there is a disconnect between the shared interphone 10 and the door-to-door interphones 41, 42,..., 61, 62,. Detected as occurring (see FIG. 4). As described above, since it is accurately determined whether or not the call is disconnected, a call can be made by the conversion call means 3 and a call can be made without waiting for recovery.

(3) The telephone number for each door interphone is stored (set) in the storage unit 2 by the setting unit 4. Not only when a new resident memorizes a new house due to a new construction, moving, or the like, but it is possible to easily memorize even when a telephone number such as a mobile phone or an IP phone is changed from a fixed phone. For example, when a mobile phone number is stored, it is possible to respond to a visitor who has visited when he / she is absent.

(4) The time notification means 5 notifies the waiting time until the call is started (see FIG. 3). A visitor etc. can not only understand the disconnection state but also prevent a misunderstanding that the resident of the dwelling unit to be called is absent.

[Other Embodiments]
Although the best mode for carrying out the present invention has been described above, the present invention is not limited to this mode. In other words, various forms can be implemented without departing from the scope of the present invention. For example, the following forms may be realized.

(1) In the above-described embodiment, the setting unit 4 is provided in the common intercom 10 (see FIG. 2). Instead of this form, each door intercom 41, 42, ..., 61, 62, ... may be provided. Similar to the above-described embodiment, the door-to-door interphone 41 will be described as a representative. As shown in FIG. 5, the door-to-door interphone 41 includes the setting unit 4 and the non-connection detection unit 1 and the non-notification notification unit 6. The functions of the setting unit 4 and the disconnection detecting unit 1 are the same as those in the above-described embodiment. The non-notification notification unit 6 notifies the non-connection state through the display a, the speaker b, or the like when the non-connection detection unit 1 detects the non-connection. However, the storage means 2 remains provided in the shared intercom 10. Therefore, the setting unit 4 uses the IP communication path 20 to input the telephone number of the telephone 51 input by the resident or the like by operating the input key d when the disconnection detection unit 1 does not detect disconnection. Store in the storage means 2.

  Here, an example of the door-to-door processing executed by the door-to-door interphone 41 will be described with reference to FIG. When a predetermined detection timing (for example, a predetermined interval such as 10 minutes) is reached (YES in step S30), a detection signal (for example, a packet) is transmitted to the shared interphone 10 and a response signal is returned. [Step S31]. When a response signal is received from the shared intercom 10 (YES in step S32), since the communication is possible, the door-to-door process is returned without detecting disconnection.

  When no response signal is received from the shared intercom 10 (NO in step S32), the above-described steps S31 and S32 are repeated until a predetermined condition is satisfied [step S33]. This predetermined condition can be set with arbitrary contents as in the above-described embodiment. If the predetermined condition is satisfied (YES in step S33), the disconnection state is notified through the display device a and the speaker b [step S34], and the door-to-door process is returned.

  According to the configuration shown in FIG. 5 and FIG. 6, the non-notification notifying means 6 notifies the non-communication state, so that a resident of a dwelling unit with the door-to-door interphones 41, 42,. Recognize the possibility that the stored phone number has a call. Therefore, a resident etc. can prepare for the call to the telephones 51, 52,..., 71, 72,.

(2) In the above-described embodiment and the form of (1), the setting means 4 is provided in the common interphone 10 and the door-to-door interphones 41, 42, ..., 61, 62, ... (see FIGS. 2 and 5). Instead of this form, a computer other than the interphone (for example, a server) may be provided. For example, a specific person can store a telephone number corresponding to the room number in the storage unit 2 from the computer by a request from a resident or the like. The same applies to the storage means 2, and not only the shared interphone 10 but also the door-to-door interphones 41, 42,..., 61, 62,.

(3) In the above-described embodiment, the telephone numbers 51, 52,... 71, 72,... Installed separately from the door-to-door interphones 41, 42,. 1). Instead of this form, when a door-to-door interphone with a telephone function is installed, the telephone number assigned to the door-to-door interphone may be stored in the storage means 2. In this case, the telephones 51, 52,..., 71, 72,.

(4) In the above-described embodiment, one telephone number is stored for one door-to-door intercom. Instead of this form, two or more telephone numbers may be stored in a single intercom intercom. In other words, a plurality of telephone numbers corresponding to one room number are stored in the storage means 2. For example, if the call is not made even if a predetermined number of times (for example, 10 times) is made by the call in step S16 of FIG. 3, the call is made with another telephone number stored in the same room number. In this way, even if the resident is away such as going out, a call can be made to a mobile phone or the like. Therefore, it is possible to respond to visitors even when they are away.

(5) In the above-described embodiment, the storage means 2 stores the telephone numbers 51, 52,..., 71, 72,. Instead of this form, an e-mail address (particularly a mobile phone) may be stored corresponding to the room number. In this way, even if the telephone line is disconnected, it is possible to notify the resident and the like that the visitor has come.
