In the extension name table 25a, a number of types such as “kokil” and a number of functions such as “alert” and “monitor” are set and stored. On the other hand, the extension name assignment table 25b stores the relationship between the associated intercom device and the extension name.
For example, the ID given to the call signal (entrance call) from the slave unit 1b is “001”, for example, and “koki1” is associated with the extension name of this device. Further, the ID attached to the alarm notification of the security device 8 is, for example, “011”, indicating that “alert” is associated with the extension name of this device. Further, the ID assigned to the monitor function of the slave unit with camera 1a is, for example, “002”, and “monitor” is associated with and stored in the extension name of this function.

  Thus, the extension name table 25a stores interphone devices that may be connected to the base unit 2 and a number of functions related to the interphone devices, and the type and function of the actually connected device are selected. It is associated with the ID and stored in the extension name assignment table 25b.

  FIG. 5 shows a circuit block diagram of the SIP server 4, an extension name storage unit 31 in which extension names registered in association with IDs in the IP conversion adapter 3 are registered, a server CPU 32 that controls communication between connected devices, and a wireless A LAN transmission / reception unit 33 and the like communicating with the router 5 are provided.

In the intercom system configured as described above, the setting operation is performed as follows. First, a type ID and a function ID are assigned to each intercom device.
Specifically, the intercom device connected to the master unit 2 is detected by the connected device detection unit 17 and is operated by the ID assigning unit 18 to receive the slave unit with camera 1a, the slave unit 1b, the electric lock 7, the master unit. Each of the 2 itself is given a predetermined ID according to the type or function. The assigned ID information is transmitted to the IP conversion adapter 3 under the control of the parent CPU 20. The ID to be assigned is determined for each type of device or for each function, and is assigned according to a predetermined rule.

In the IP conversion adapter 3, the command conversion control unit 29a receives the ID information transmitted in response to the ID assigning operation, and converts the intercom command to the SIP command.
Thereafter, the extension name registration control unit 29a compares the received ID information of the intercom device with the registration information in the extension name table 25a, and controls whether there is an extension name that can be assigned. As a result, if there is an extension name that can be assigned, the relationship between the ID and the extension name is registered in the extension name assignment table 25b. At the same time, the registered extension name is transmitted from the LAN transmitting / receiving unit 28 to the SIP server 4.
In the SIP server 4, the extension name received by the server CPU 32 via the LAN transmission / reception unit 33 is registered in the extension name storage unit 31. As a result, extension names such as “koki1” and “monitor” are registered in the extension number storage unit 31.

  On the other hand, the IP terminal 6 also transmits the extension name corresponding to itself to the SIP server 4 via the wireless router 5, and, for example, the extension name “101” is registered. The extension name only needs to be identifiable information, and may be a numeric string in this way.

When the settings of the individual intercom devices are made in this way, the call / answer operation is performed as follows. First, the operation of the entrance call by operating the handset 1 will be described. When a visitor presses the call button 12 of the handset 1 a with camera among the handset 1, a call signal is transmitted to the base unit 2. In the base unit 2 that has received the call signal, the base unit CPU 20 sounds a ringing tone from a speaker (not shown). In addition, the captured image of the camera 11 activated by the calling operation is transmitted to the parent device 2. In response to this video signal, the master CPU 20 causes the monitor 14 to display the video.
Further, the base CPU 20 generates a call command to which an ID corresponding to the entrance call is assigned, and transmits it to the IP conversion adapter 3 together with the video signal.

  In the IP conversion adapter 3, when the IP conversion adapter CPU 29 receives the calling command to which the ID is assigned via the command transmission / reception unit 27, the command conversion control unit 29b converts the interphone protocol into the IP signal, and the extension name assignment table 25b. And a corresponding extension name “koki1”) is assigned. The call command to which the extension name is assigned is transmitted from the LAN transmitting / receiving unit 28 to the SIP server 4. The video signal received at this time is also transmitted.

  When the server CPU 32 receives the call command via the LAN transmission / reception unit 33, the SIP server 4 converts the call command into a SIP command and transmits it to the IP terminal 6 via the wireless router 5. In addition, the video signal is also converted into a format that can be displayed on the display unit 6a of the IP terminal 6 and transmitted.

  Upon receiving this command, the IP terminal 6 performs a call notification operation such as a ringing tone and simultaneously displays the extension name “koki1” given to the received command on the display unit 6a. In addition, a video is displayed on the display unit 6a based on the received video signal. Thus, the resident carrying the IP terminal 6 can recognize from the display that the call notification is a call from the visitor, and can confirm the visitor from the displayed video.

  Then, a communication path is formed between the device that has been responded to either the parent device 2 or the IP terminal 6 and the camera-equipped child device 1a that transmitted the calling signal, and the resident can talk to the visitor. It becomes. Thereafter, by performing the end-of-call operation, the handset 1 and the base unit 2 or the IP terminal 6 that has made a response return to the standby state. When the handset 1b not having the camera 11 is called, only the call signal or the call command is transmitted to the base unit 2 and the IP terminal 6, and no video is transmitted.

  Next, an operation of starting the camera of the camera-equipped child device 1a from the IP terminal 6 and monitoring the entrance where the camera-equipped child device 1a is installed by the IP terminal 6 will be described. When the operation unit 6 b of the IP terminal 6 is operated and an extension name “monitor” is input, an SIP call signal corresponding to “monitor” is transmitted to the SIP server 4 via the wireless router 5. When the server CPU 32 receives the SIP call signal via the LAN transmission / reception unit 33, the server CPU 32 compares it with the extension name registered in the extension name storage unit 31. Since the extension name “monitor” is registered, the SIP call signal corresponding to “monitor” is transmitted to the IP conversion adapter 3.

  In the IP conversion adapter 3 that has received this SIP call signal, an ID for activating the monitor function is read from the extension name assignment table 25b under the control of the IP conversion adapter CPU 29, and the command converted into the interphone protocol is the parent. Is transmitted to the machine 2.

  When receiving the monitor command, the base unit 2 analyzes the base unit CPU 20 and performs control for driving the camera 11 of the slave unit with camera 1a. Thereby, the video imaged by the camera 11 of the camera-equipped slave unit 1a is transmitted to the IP terminal 6 via the parent device IP conversion adapter 3 and the wireless router 5, and displayed on the display unit 6a of the IP terminal 6. When the monitor operation is performed from the master unit 2, a monitor button (not shown) is provided. By operating this button, the camera 11 is activated and the entrance video is displayed on the master monitor 14. .

As described above, the IP conversion adapter registers the ID and extension name group classified according to the type or function of the interphone device, and the SIP server registers the extension name that permits communication. When performing communication with a device, it is possible to call by extension name, and it is possible to simultaneously perform a communication path forming operation and a desired control operation. As a result, it is not necessary to perform a two-step operation such as sending a necessary instruction command such as a monitor operation after calling a living room base unit or the like to form a communication path as in the prior art.
In addition, when the command is received from the interphone device, the device information and function information of the command transmission source are displayed on the IP terminal as an incoming call display, so that the IP terminal user can grasp the transmission source before performing a response operation. Easy to handle.

In the above embodiment, the SIP server 4 is provided independently, but may be integrated with the IP conversion adapter 3 and the wireless router 5.
In addition, this intercom system can also be applied to a collective housing intercom system. In this case, a collective entrance machine is connected to the master unit 2 via a controller. The terminal 6 can respond, and the IP terminal 6 can be used to unlock the electric lock of the door provided at the collective entrance.
