  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 interphone system according to the present invention. 1 is an interphone slave set installed at the entrance of a facility such as an educational facility or a hospital for a visitor to call a staff member in the facility. 2 is an interphone master unit that is installed in the facility and responds to calls from interphone slave units, 3 is a controller that controls calling and calling and various settings, and 4 is a broadcasting speaker (broadcasting SP). is there.

The intercom handset 1 is connected to the controller 3 via a transmission line L1, the interphone base unit 2 is connected to the controller 3 via a transmission line L2, and the broadcasting speaker 4 is connected to the controller 3 via a transmission line L3.
One or a plurality of interphone slave units 1 are installed in accordance with the number of entrances, and interphone master units 2 are also installed at a plurality of locations so that staff members in the facility can respond. The broadcasting speaker 4 is also the same, and is installed at an appropriate position according to the size and layout of the facility. However, in FIG. 1, for convenience, the interphone slave unit 1, the interphone master unit 2, and the broadcasting speaker 4 are each two.

  FIG. 2 shows the main part of each device as a circuit block, and the intercom handset 1 is provided with an imaging unit 7 for imaging a visitor with a camera, a call button 8 for calling a staff member, a microphone 9a, and a speaker 9b. The communication unit 9 includes a slave unit control unit 10 that controls the interphone slave unit 1 as a whole, a slave unit communication unit 11 that communicates with the controller 3, and the like.

  The interphone master unit 2 includes a display unit 14 including an LCD for displaying an image captured by the imaging unit 7 of the interphone slave unit 1, an operation for setting a response operation or “absence mode” described later, and calling another interphone master unit 2 An operation unit 15 for performing various operations such as operations and further operations of the imaging unit 7, a call unit 16 having a microphone 16a and a speaker 16b, a base unit control unit 17 for controlling the intercom base unit 2 as a whole, and a control unit 3 A base unit communication unit 18 and the like are provided.

  The controller 3 includes an audio storage unit 21 for storing audio messages for making various announcements, a broadcast unit 22 for transmitting audio messages to the broadcasting speaker 4 and broadcasting, the interphone slave unit 1 and the interphone master unit 2. Communicating with the intercom handset 1 and the control unit control unit 23 that performs various controls such as control of calling / calling between the devices, control of calling / calling between the interphone master units 2, and control of the sound reported from the broadcasting speaker 4 A controller first communication unit 24a, a controller second communication unit 24b communicating with the intercom master unit 2, and the like.

  Note that the voice storage unit 21 may be a voice synthesis unit that synthesizes and outputs voice. For example, arbitrarily set terminal names can be broadcast by speech synthesis using middleware such as a text-to-speech synthesis IC (S1V30120) manufactured by Seiko Epson Corporation or RubyTalk manufactured by NEC Corporation.

  The intercom system configured as described above operates as follows. The calling operation from the intercom handset 1 will be described first. When a call button 8 of the intercom handset 1 is pressed by a visitor or the like, a call signal is transmitted from the handset controller 10 to the controller 3 via the handset communication section 11 and the transmission line L1. The controller control unit 23 that has received the call signal via the controller first communication unit 24a transmits the call signal to the interphone master units 2 and 2 via the controller second communication unit 24b and the transmission line L2. When the base unit control unit 17 of the intercom base unit 2 receives the calling signal, the base unit control unit 17 sounds a ringing tone from the speaker 16 b of the calling unit 16. The camera of the imaging unit 7 starts imaging in conjunction with the calling operation, and the captured image follows the same path as the calling signal and is displayed on the display unit 14.

  When the intercom base unit 2 is operated in a predetermined response by a staff member who has noticed this ringing tone, the base unit control unit 17 generates a response signal and transmits the response signal from the base unit communication unit 18 to the control unit 3 through the transmission line L2. Is done. Upon receiving the response signal, the controller 3 forms a communication path between the interphone slave unit 1 and the interphone master unit 2 that has made a response operation under the control of the controller control unit 23. In this way, a call can be made between the visitor and the staff, and the staff can make a call while watching the video of the visitor. Thereafter, when the interphone master unit 3 performs a predetermined call termination operation, a disconnect signal is transmitted to the control unit 3 to disconnect the connected speech path, and the interphone slave unit 1 and the interphone master unit 2 enter the standby state. Return.

However, if a response operation is not performed for a predetermined time, for example, 30 seconds after the call operation is performed, the controller control unit 23 selects and extracts a predetermined voice message from the voice storage unit 21, and sends it through the broadcast unit 22. The broadcast speaker 4 is notified that a call is made from the intercom handset 1. For example, a voice message “There is a call from the entrance” is selected and reported. The controller control unit 23 includes a timer that counts a predetermined time after the call operation is performed, and a count time such as 30 seconds is set when the system is installed.
When the staff who listens to the broadcast returns to the seat and operates the interphone master unit 2, the controller 3 forms a communication path between the two, and performs the above-described control to connect the visitor and the staff. Calls can be made between them.

  The controller control unit 23 also transmits the selected voice message to the interphone slave unit 1, and sends the same message from the speaker 9 b of the interphone slave unit 1 in accordance with the report sound from the broadcasting speaker 4. Make a report.

In this way, when a call is made by a visitor and no response is made even after a certain period of time, the broadcaster automatically reports that there is a visitor, so the visitor who has left his / her seat will be notified. Can be notified that there is. Also, since the broadcast is not performed until a predetermined time has elapsed, if the response operation is performed at a normal timing, the call cannot be made by the broadcast, so that the broadcast can be prevented from becoming noise.
Furthermore, when the call broadcast is playing, the voice is also heard from the interphone slave unit, so the visitor can wait with peace of mind by listening to the broadcast, and the content being broadcast is kept as it is. It is not necessary to create a separate audio from the intercom handset.

  Next, the call operation from the intercom handset 1 when the intercom base unit 2 is set to the “absence mode” will be described. First, when an employee leaves the place where the intercom master unit 2 can be operated after taking his / her seat away, the absence mode is set by operating the operation unit 15. By this setting operation, the absence setting signal is transmitted from the parent device control unit 17 to the control device 3 via the parent device communication unit 18 and the transmission line L2. When the absence control signal transmitted to the controller 3 is received by the controller control unit 23 via the controller second communication unit 24b, the controller 3 recognizes that the interphone master unit 2 is set to the absence mode. Note that the absence mode is set by each interphone master unit 2, and the controller 3 recognizes the state of each interphone master unit 2.

  When a visitor presses the call button 8 of the intercom handset 1 while any one of the interphone base units 2 is set to the “absence mode”, the call signal passes through the control unit 3 in the same manner as the above operation. Then, it is transmitted to the intercom base unit 2, and a ringing tone is generated from the speaker 16 b of the call unit 16 under the control of the base unit control unit 17.

  However, the controller control unit 23 that recognizes that the interphone master unit 2 is set to the “absence mode” transmits a call signal to the interphone master unit 3 and at the same time receives a predetermined voice message from the voice storage unit 21. Is selected and taken out, and a notification is made that a call is made from the intercom handset 1 from the broadcasting speaker 4 via the broadcasting unit 22. Further, the extracted voice message is also transmitted to the interphone slave unit 1 via the controller first communication unit 24a, and the speaker 9b of the interphone slave unit 1 reports that the call is made from the interphone slave unit 1. Let it sound. For example, a voice message “There is a call from the entrance” is selected and reported.

  In this way, when a staff member who listens to the broadcast returns to the seat and operates the intercom master unit 2 and responds in the same manner as described above, the controller control unit 23 performs the above-described communication path formation control to form a communication path and visit Calls can be made between the person and the staff. It should be noted that it may be configured to broadcast simultaneously with the call operation only when all interphone master units 2 and 2 are set to the “absence mode” instead of any one.

  In this way, by setting the absence mode, when a call is made by a visitor, a call is made to the interphone master unit, and at the same time, the presence of a visitor is reported by broadcasting, so the corresponding staff member will be intercom parent. Even if you are not near the machine, you can be notified that there is a visitor without time delay, and smooth response is possible.

  Next, a call / response operation between the interphone master units 2 will be described. When a predetermined operation for selecting and calling another interphone master unit 2 is performed by any interphone master unit 2, a call signal is transmitted to the controller 3. Receiving this call signal, the controller control unit 23 transmits the call signal to the interphone master unit 2 that is the call destination, and the selected interphone master unit 2 rings the ring tone. When a response operation is performed in response to the ringing sound, the controller control unit 23 forms a communication path between the call source interphone master unit 2 and the selected call destination interphone master unit 2 according to the response signal, Calls can be made between the two parties.

However, if a response operation is not performed for a predetermined time, for example, 30 seconds after the call operation is performed, the controller control unit 23 selects and extracts a predetermined voice message from the voice storage unit 21, and sends it through the broadcast unit 22. The broadcast speaker 4 is notified that a call has been made from the intercom base unit 2. For example, a voice message “No. 2 master is called” is selected and reported.
When a staff member who has heard this broadcast returns to his / her seat and performs a call operation on the interphone master unit 2 that has been called, the controller control unit 23 forms a communication path between the two, and performs the above-described control to perform the staff operation. Calls can be made between each other.

  When the interphone master unit 2 set to the “absence mode” is called from another interphone master unit 2, the controller 3 performs the following control. When the intercom base unit 2 is set to the absent mode, the controller 3 recognizes the intercom base unit 2 set to the absent mode as described above. When any one interphone base unit 2 is set to this “absence mode” and another interphone base unit 2 calls the interphone base unit 2 in the “absence mode” state, first, the interphone base unit to be called Call is made to the base unit 2.

  At the same time, the controller control unit 23 recognizing that the interphone master unit to be called is set to the “absence mode” selects and retrieves a predetermined voice message from the voice storage unit 21, and Via the broadcast speaker 4, a notification is made that a call is made from another intercom master unit 2. For example, a voice message “No. 2 master is called” is selected and reported.

  Thus, when a staff member who has noticed the call after listening to the broadcast returns to the seat and operates the intercom master unit 2 to perform a response operation, the controller control unit 23 performs the above-described call path formation control to form the call path. This makes it possible to talk between staff.

In this way, when there is no response for a certain period of time when another interphone master unit is called from the interphone master unit, it automatically broadcasts that a call is made to the other interphone master unit. It is possible to notify that the staff is called even if the staff is out of the seat. Moreover, since it does not broadcast until a fixed time passes, if it is not in a hurry, it is possible to prevent the broadcast from becoming noise if the call is terminated before broadcasting.
Also, if the absence mode is set, when an interphone master unit in the absence mode is called by another interphone master unit, it will be broadcast that the call has been made without delay. It can be notified that there is no delay in being called.

  In the above embodiment, when the call is broadcast from the interphone handset 1, the interphone handset 1 reports the same message when the call is broadcast. May be a message different from the broadcast such as “I am calling now”.

It is a block diagram which shows an example of embodiment of the intercom system which concerns on this invention. It is the block diagram which showed the principal part of each apparatus of FIG. 1 with the block diagram.
