DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram showing a first form of an intercom apparatus according to the present invention, wherein 1 is a telephone set installed at a place visited by a visitor such as a front door, and 2 is a call. Calling handsets 4 installed in the vicinity of the handset 1 to call a visited place are interphone masters (hereinafter simply referred to as “masters”) installed in the room and responding to calls. Are connected by a communication line via HUB5. Each of the handset 1, the handset 2, and the base 4 has a unique IP address, and performs transmission / reception of data signals, digital audio signals, and digital video signals according to the IP protocol.
Then, the intercom handset 1 and the call handset 2 constitute an interphone handset (hereinafter simply referred to as “slave unit”) 3 in which a visitor calls a destination and makes a call.

  FIG. 2 is a circuit block diagram showing the device shown in FIG. As shown in FIG. 2, the telephone handset 1 includes a handset camera 11 for imaging a visitor, a microphone 13 and a speaker 12 for talking to a called party, and a human sensor 14 for sensing the approach of the visitor. , A storage unit 15 for storing the IP address of the connected device, a telephone set CPU 16 for controlling each unit of the telephone set 1 and the like. The telephone handset 1 does not have a call button and does not have a function for calling a resident.

  The calling device 2 includes a child device display 21 in which a list of call destinations is displayed by a plurality of calling buttons (not shown), and an operation unit provided on the child device display 21 for operating the displayed calling buttons. Touch panel 22, a storage unit 23 for storing the IP address of the connected device, a caller CPU 24 for controlling each part of the caller 2, and the like.

  The base unit 4 includes a microphone 41 and a speaker 42 for responding to a call, a base unit display 43 that displays a captured image of the handset camera 11, and a call operation unit that receives the call signal and forms a communication path with the handset 1. 44, an image storage unit 45 for storing a guidance image made up of character information for explaining a call status to a visitor, a parent camera 46 for imaging a responder, and a parent for controlling each unit of the parent unit 4 A machine CPU 47 and the like are provided.

Next, the operation of the intercom apparatus configured as described above, particularly the call operation will be described. FIG. 3 is a flowchart showing the flow of operation of the intercom device that has been visited by a visitor and has received a call operation, and shows the operation separately for each device. This will be described below based on this flow.
When a visitor comes to the entrance, the human sensor 14 of the telephone handset 1 senses the visitor (S1). In response to this detection, the calling handset CPU 16 refers to the IP address of the calling handset 2 stored in the storage unit 15 and transmits an activation signal to the calling handset 2 (S2).

  The caller unit 2 that has received the activation signal via the HUB 5 is controlled by the caller unit CPU 24 and, for example, a company interphone device, a plurality of callees (call buttons) such as “reception” and “general affairs department” Is displayed on the handset display 21 (S3).

When a visitor confirming the display content of the slave display 21 selects a visit destination on the touch panel 22 (YES in S4), the call slave CPU 24 calls a call with an ID added to the selected master unit 4 A signal is generated and transmitted to the telephone handset 1 (S5). Transmission to the handset 1 is performed by setting the IP address of the handset 1 as the destination. The IP address is registered in the storage unit 23 in advance.
The transmission of various signals is similarly performed by setting the IP address as the transmission destination.

  The telephone handset 1 that has received the calling signal from the calling handset 2 (S6) is added when the calling handset CPU 16 confirms from the IP address information that it is a signal transmitted from the calling handset 2 (S8). The IP address information of the base unit 4 is read from the storage unit 15 based on the base unit ID information, and this IP address is set as a transmission destination to transmit a call signal. In this way, the call signal is transmitted to the callee base unit 4. The caller CPU 16 that has recognized that the signal is from the caller 2 makes a call confirmation sound from the speaker 12, activates the microphone 13 and the child camera 11 (S9), and collects the visitors. And the video signal of the slave camera 11 are transmitted to the called master device 4 (S10).

  Note that the calling signal may be transmitted directly from the calling device 2 to the parent device 4. In this case, it can be easily implemented by setting the IP address of the base unit 4 as the transmission destination, as in the case of transmission to the handset 1.

The base unit 4 that has received the calling signal generates a ringing tone from the speaker 42 under the control of the base unit CPU 47 and displays the video signal of the handset camera 11 transmitted from the telephone handset 1 on the base unit display 43. . When a visitor's voice is transmitted, a sound is reported from the speaker 42 (S11).
Further, the base unit CPU 47 reads the guidance image from the image storage unit 45 and transmits it to the calling unit 2 (S12). Receiving the image signal, the handset CPU 24 displays the received guidance image on the handset display 21 (S13). Thus, for example, in the case of the handset 3 of the office building, the handset display 12 displays the guidance image including the character information “I am currently calling the General Affairs Department”. Further, for example, when the call is transferred from the called parent device 4 to another parent device 4, a guidance image such as “Please wait for a while” is displayed. By this display, the call status can be notified to a visitor waiting for a response.
As described above, since the guidance image is displayed on the child device 3 after the calling operation, the visitor can recognize the calling status and can be relieved.

Thereafter, when a person near the parent device 4 who has confirmed the visitor by the ringing tone and the visitor image performs a response operation on the call operation unit 44 of the parent device 4, the microphone 41 in addition to the speaker 42 in which the parent device CPU 47 is active. Is activated, and a communication path forming signal is transmitted to the telephone set 1. Further, the master camera 46 is activated, and the captured image is transmitted to the calling device 2.
The call slave CPU 16 that has received the call path formation signal activates the speaker 12 to form a call path with the parent machine 4 and enables a call. In addition, the caller CPU 24 that has received the video signal causes the slave device display 21 to display a captured image of the master camera 46.
In this way, since the video of the person who responds from the callee base unit 4 is displayed on the caller unit 2, the visitor can easily talk and feel safe. In addition, since the video is displayed using the touch panel 22, it is not necessary to provide a separate display means.

  On the other hand, the telephone slave CPU 16 starts a timer (not shown) when the human sensor 14 detects a visitor, and starts counting a predetermined time such as 10 seconds. Then, when this predetermined time has elapsed without the caller 2 being operated (YES in S7), an announcement prompting the call operation from the speaker 12, for example, “Please touch the call destination” is sounded ( S14). This announcement sound is stored in the storage unit 15 in advance. Further, the telephone handset CPU 16 transmits a stay signal to the handset 2 (S15). Receiving the stay signal, the caller CPU 24 performs a guidance operation for blinking the screen to prompt a call operation (S16). After that, if there is no transmission of the calling signal and a predetermined time has elapsed, the call slave CPU 16 automatically transmits the calling signal to the parent device 4 designated in advance. Thus, if there is a response from the parent device 4, a call can be made.

  Note that a predetermined guidance image may be displayed based on the stay signal, and by storing it in the storage unit 23 of the caller 2, the caller CPU 24 reads out the stay signal and displays it on the handset display 21. Can be made.

As described above, when the calling handset 1 for calling and the calling handset 2 for selecting the call destination are separated, the name of the call destination, the number of the parent handsets 4 and the like are changed. The handset 3 can be changed only by the calling handset 2, and it is not necessary to change the handset 1 and can be implemented at a relatively low cost. The change in the number of master units 4 can be handled by changing the call button display on the slave unit display 21 and the like, and can flexibly cope with changes in the installation environment of the intercom device.
Also, when the visitor is confused about the operation method of the caller 2, voice guidance and guidance operations are performed, which is useful for calling the visited party, and a call signal is received from the caller 2 due to a malfunction or the like. If not output, the specific intercom base unit 4 performs a call operation, so that a visitor does not determine that a resident is absent because a call signal is not output.

FIG. 4 is a block diagram showing a second embodiment of the intercom apparatus according to the present invention. Hereinafter, the second embodiment will be described with reference to FIG. Here, the point that the paging device 2 is a portable paging device 6 carried by a visitor is greatly different from the above embodiment.
As this portable handset 6, a mobile phone or a tablet terminal having an identification ID such as an IP address, a MAC address, or a mobile phone number can be used. The HUB 5 has a communication antenna 5a for performing wireless LAN communication, and is connected to an external network N such as a mobile phone network or the Internet. Therefore, when the portable handset 6 is a mobile phone, it can communicate with the present intercom apparatus via the external network N, and can also communicate using a wireless LAN.

FIG. 5 shows each device of FIG. 4 in a circuit block. Hereinafter, the difference will be mainly described with reference to FIG. The telephone handset 1 includes a handset camera 11, a microphone 13, a speaker 12, and a storage unit 15 and a portable device detection unit 17 that detects the strength of a wireless LAN signal output from the portable handset 6; A function is provided for detecting that the portable handset 6 is near the handset 1. In addition, the storage unit 15 stores an identification ID such as an IP address or a MAC address of the portable handset 6.
Note that the presence of the portable handset 6 causes the portable handset 6 to output an ultrasonic signal or DTMF signal that can be collected by the microphone 13 of the handset 1 instead of a radio signal, and outputs the signal to the handset. You may make it recognize by making 1 detect.

  The portable handset 6 includes a handset display 61 that displays a list of callees by a plurality of call buttons, a touch panel 62 as an operation unit provided on the handset display 61 for operating the call button, an interphone handset. Storage unit 63 for storing the IP address and the like of a device that communicates when used as a portable handset CPU 64 for controlling the portable handset 6 as a whole, for performing wireless LAN communication or wirelessly connecting to an external network N Wireless communication unit 65 and the like. Note that the image data of the call button displayed on the child device display 61 is installed when the IP address of the connected device is registered.

Next, the operation of the intercom apparatus configured as described above, particularly the call operation will be described. FIG. 6 is a flowchart showing the flow of operation of the intercom device when a visitor carrying the portable caller 6 performs a call operation, and shows the operation separately for each device. This will be described below based on this flow.
At the entrance where the handset 1 is provided, the portable handset 6 is activated (S101). When a predetermined display operation is subsequently received, a call destination (call button) is displayed (S102). With this display, the portable handset CPU 64 transmits an activation signal including the ID information of the portable handset 6 to the IP address of the visited handset 1 registered in advance by the wireless LAN.

Upon receiving this activation signal via the HUB 5 (S105), the telephone handset 1 waits for reception of the calling signal by the telephone handset CPU 16 with the portable device detection unit 17 active.
The activated portable handset 6 displays a call destination list including a plurality of call buttons by a predetermined operation, and when one of them is pressed to perform a call operation (YES in S103), A call signal including the ID information is transmitted to the handset 1 via the HUB 5 (S104). The call signal is implemented by wireless LAN communication and is transmitted to the IP address of the handset 1.

  Upon receiving this call signal (YES in S106), the handset CPU 16 stores in the storage unit 15 the identification ID such as the IP address or MAC address of the portable handset 6 that is the call signal transmission source. If the ID matches the ID (YES in S107), it is determined whether the portable handset 6 is near the handset 1 (S108). If the portable device detection unit 17 receives a wireless LAN signal such as a call signal and determines that the strength is equal to or higher than a predetermined level, it is determined that the portable handset 6 that has been operated for calling is in the vicinity (YES in S108). In the same manner as in the first embodiment, the IP address information of the parent device 4 is read from the storage unit 15 from the added parent device ID information, and this IP address is set as the transmission destination and a call signal is transmitted. In this way, the call signal is transmitted to the callee base unit 4.

  The portable device detecting unit 17 determines the position of the portable handset 6 other than a wired signal such as DTMF or an ultrasonic signal having a frequency of 15 to 20 KHz instead of the strength of the wireless LAN signal. May be determined based on the received intensity.

  The caller CPU 16 that has recognized that the signal is from the caller 2 makes a call confirmation sound from the speaker 12, activates the microphone 13 and the child camera 11 (S109), and collects the visitors. And the video signal of the slave camera 11 are transmitted to the called master device 4 (S110).

  In the base unit 4 that has received the call signal, the base unit CPU 47 causes the speaker 42 to ring a ringing tone, and displays the video signal of the handset camera 11 transmitted from the call handset 1 on the base unit display 43. Further, when the visitor's voice is transmitted, a sound is reported from the speaker 42 (S111). Further, the base unit CPU 47 reads a guidance image from the image storage unit 45 and transmits it to the portable handset 6 (S112). The portable handset CPU 64 that has received the image signal displays the received guidance image on the handset display 61 (S113).

  Thus, for example, in the case of the handset 3 of the office building, the handset display 61 displays the guidance image including the character information “I am currently calling the General Affairs Department”. Further, for example, when the call is transferred from the called parent device 4 to another parent device 4, a guidance image such as “Please wait for a while” is displayed. By this display, the call status can be notified to a visitor waiting for a response.

Thereafter, when a person near the parent device 4 who has confirmed the visitor by the visitor image displayed as a ringing tone responds to the call operation unit 44 of the parent device 4, in addition to the speaker 42 in the active state, the microphone 41 Becomes active, and the master CPU 47 transmits a call path formation signal to the call slave 1. At the same time, the base camera 46 starts imaging, and the captured video is transmitted to the calling handset 2.
The call slave CPU 16 that has received the call path formation signal activates the speaker 12 to form a call path with the parent machine 4 and enables a call. In addition, the portable call slave CPU 64 that has received the video signal displays the captured video of the master camera 46 on the slave display 61.

  In the embodiment of FIG. 4, the presence of the portable handset 6 is detected by receiving a radio signal. However, the human sensor 14 is provided in the same manner as in the embodiment of FIG. May be detected.

As described above, since the calling device 2 is the portable calling device 6, it is possible to use a mobile phone or a tablet terminal carried by a visitor as the calling device 2. Only a handset is required to be installed, and equipment installed on the dwelling unit side can be configured at low cost. Further, the change in the number of base units 4 can be dealt with by changing the button display on the touch panel 62, etc., and can flexibly cope with the change in the installation environment of the intercom device.
In addition, since a call signal from an unregistered portable caller 6 is not accepted, even if the portable caller 6 is a general-purpose portable terminal, a call path from a malicious visitor is established. You can reject the request.
Further, if the strength of the wireless LAN signal is lower than a predetermined level, that is, if the portable handset 6 is not near the handset 1, even if a call signal is transmitted from a registered device, it is not accepted. Even if the portable handset 6 registered in the neighboring dwelling unit is operated, it is not recognized that the mobile handset 6 is being called, and malfunction can be prevented.
Further, when the calling function of the portable handset 6 does not operate due to a failure or the like, the specific base unit 4 is called. Therefore, the visitor does not determine that the resident is absent because the call signal is not output.

  In any of the above embodiments, video transmission is performed bidirectionally. However, when the line capacity is not sufficient, only voice communication is performed bidirectionally. It is good also as one-way to.
