  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments of the invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an example of an intercom system according to the present invention, in which 1 is an entrance cordless handset installed outside the entrance to call a resident, 2 is a living room base phone for answering the call, 4 is an Internet network (Internet), and 5 is a server (communication management server) that controls communication between the living room parent units 2, and the individual room parent unit 2 and the server 5 are connected to the Internet network 4. In addition, the gateway device 1 and the living room parent device 2 connected by the transmission line L1 constitute a set of interphone devices 3.

  The front door 1 has a call button 1a, a microphone 1b and a speaker 1c for a call, and a camera 1d that images a visitor. When the call button 1a is pressed, a call signal is transmitted to the room master 2; The camera 1d is activated and the captured video is transmitted to the room master unit 2. On the other hand, the living room base unit 2 has a call button 2a for answering a call, a microphone 2b and a speaker 2c for a call, and a monitor 2d composed of an LCD for displaying an image captured by the camera 1d. The touch panel 7 as an operation unit is assembled.

  FIG. 2 is a circuit block diagram of the living room master unit 2, 8 is an entrance slave unit control circuit for controlling the entrance slave unit 1, 9 is a video display circuit for controlling the display of the monitor 2d, and 10 is an operation button on the monitor 2d. A touch panel control circuit that displays and controls the touch panel 7, 11 is a network connection circuit for connecting to the Internet network 4, and 12 is a master CPU that controls the living room master 2.

  The touch panel 7 has an external transfer button (not shown) for transmitting a call signal from the entrance terminal 1 to the server 5 via the Internet 4, and an external call button for making a call with the external room master 2. (Not shown) is provided. Both buttons are displayed on the monitor 2d by a predetermined touch panel operation.

  FIG. 3 shows a block diagram of the main part of the server 5, 16 is a connection information storage unit that stores connection permission information of the living room base unit 2, 17 is a network interface (network IF) that communicates with the Internet network 4, and 18 is the server 5. The server CPU which controls is shown. Specifically, the connection information storage unit 16 has a transmission table 16a in which a signal transmitted from the room master 2 to each room master 2 is registered, and which room. The server 5 includes a permission table 16b that receives a signal transmitted from the parent device 2 and permits connection or registers a connection-permitted partner, and the server 5 controls connection between the room parent devices 2 according to this information.

FIG. 4 shows a specific example of this connection permission information. (A) is a transmission table 16a, and (b) is a permission table 16b. For example, in the transmission table 16a, when looking at the room master device 2 with ID000001 (hereinafter referred to as parent device A), the signal sent from the parent device A is the room master device 2 with ID000002 (hereinafter referred to as parent device B). ) Indicates that the server 5 controls to be transmitted to the room master unit 2 with ID000003 (hereinafter referred to as “base unit C”). On the other hand, in the permission table 16b, since the parent device A gives connection permission only to the parent device B with ID000002, the server CPU (connection control means) 18 of the server 5 connects to the parent device A from the parent device B. Only the request is accepted, and the connection operation is not performed even if there is a connection request from the other base unit 2 to the base unit A.
In this way, by separately performing the setting of the transmission destination and the setting of the connection permission destination, even if the setting is performed by the touch panel operation of each room master unit 2, it can be set without any problem in terms of security. Specifically, the server 5 is preferably an ASP (Application Service Provider).

  The intercom system configured as described above operates as follows. First, the intercom device 3 performs the same operation as the conventional one. When the call button 1a of the entrance cordless handset 1 is pressed by a visitor or the like, a call signal is transmitted to the room base unit 2, and the room base unit 2 reports a ringing tone. At the same time, the camera 1d is activated and an image of the visitor is transmitted to the living room main unit 2, and when the resident who receives the ringing tone presses the call button 2a, a call is performed with the front door unit 1. The When the ringing tone is reported, the monitor 2d is activated and a visitor video imaged by the camera 1d is displayed, and the resident can respond while watching the video.

Then, when the external transfer button is operated by a predetermined operation of the living room main unit 2, the living room main unit 2 enters a call transfer mode. An external call signal to which ID information is added is transmitted to the server 5 via the Internet 4 under the control of the CPU (call control means) 12.
The server 5 that has received this external call signal selects a transmission destination with reference to the connection information storage unit 16 based on the ID information included in the signal. At this time, both the transmission table 16a and the permission table 16b are referred to. From the received signal, the call destination associated with the transmission source room parent device 2 is read from the transmission table 16a, and the permitted parent device having the read call destination room parent device 2 as the main parent device is read from the permission table 16b. If the calling parent room 2 is registered in this permitted parent machine, the call path is connected and the calling destination parent machine 2 is called.

For example, in the setting state of the table shown in FIG. 4, when the external transfer button of the parent device A is operated, the server 5 is controlled to transmit to the parent device B and the parent device C with reference to the transmission table 16a. Try to do. However, referring to the permission table 16b, although the parent device B gives connection permission to the parent device A and the parent device C, the parent device C gives no connection permission to any of the parent devices. 5 performs a call operation with only the parent device B that has given connection permission to the parent device A as the permitted parent device.
The room master unit 2 that has received the call signal in this manner rings a ringing tone under the control of the base unit CPU 12, and then presses the call button 2a. Calls can be made between them.

In this way, since the communication management server selects and connects to the connection partner according to the transmission source room master unit, unregistered room master units or third parties cannot enter (connect) via the Internet. Therefore, security can be maintained. And even if you are away, you can respond to visitors from other dwelling units, which is effective for crime prevention.
Also, the connection permission information consists of a transmission table and a permission table. Since the room master specified as the destination does not permit the connection to the room master of the transmission source, one side registers the communication partner. You can't make a call just by doing. For example, even if a third party intrudes into the communication management server and tries to communicate with the living room master unit and rewrites either the transmission table 16a or the permission table 16b, the server does not connect the communication path. Security can be maintained even if the base unit is connected to the Internet.

  When the external call button is operated, it operates as follows. When the external call button is pressed, a call signal to which ID information is added is sent to the server 5 on the Internet network 4 under the control of the master CPU (call control means) 12. The server 5 that has received the call signal selects a call destination by referring to the connection information storage unit 16 based on the ID information included in the signal under the control of the server CPU 18. At this time, both the transmission table 16a and the permission table 16b are referred to. From the received call signal, the call destination associated with the transmission source room base unit 2 is read from the transmission table 16a.

Next, an authorized parent device whose main device is the called destination room parent device 2 is read from the permission table 16b, and if the calling origin room parent device 2 is registered in this authorized parent device, both communication paths are set. Connect and send a call signal to the callee room master unit 2 to perform a call operation.
The room master unit 2 that has received the call signal in this way sounds a ringing tone under the control of the base unit CPU 12, and when the call button 2a is pressed thereafter, the room base unit 2 in a different residence from the room base unit 2 that operated the external call button. Calls can be made between the two.

  In this way, it is possible to conduct a call between room base units of different dwelling units, and it can be performed by a one-touch operation only by operating an external call button. Therefore, it is effective for crime prevention, and it is convenient for elderly residents to call nearby residents or to make emergency calls.

  When a plurality of room master units 2 are registered as the transmission destination base unit and the connection permission base unit, a call signal and a call signal are transmitted to the plurality of room base units 2 at the same time. On the other hand, if it is not registered, even if the server 5 receives a call signal or a call signal, no call is made to any room master unit 2.

It is a block diagram which shows an example of embodiment of the intercom system which concerns on this invention. It is a block diagram of a living room master. It is a block diagram of a server. The content of the communication permission table memorize | stored in the server is shown, (a) is a transmission table, (b) is a permission table.
