It is a block diagram which shows an example of the business intercom system which concerns on this invention, and showed each apparatus with the circuit block.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments of the invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory diagram showing an example of a business intercom system according to the present invention, wherein 1 is a master unit having a function of calling and talking, 2 is a controller for controlling communication between connected devices, 3 is an entrance, etc. It is a handset for visitors to call and install. FIG. 1 shows a configuration in which two master units 1 are provided, and the master unit 1 and the slave unit 2 are connected to the controller 2 by transmission lines L1, L1, and L2, respectively.

  The base unit 1 includes an operation unit 11 for performing various operations such as calling and calling, a base unit speaker 12 and a base unit microphone 13 used for calling and calling, and a calling unit 14 for controlling the base unit speaker 12 and the base unit microphone 13. , A display unit 15 for displaying various information, a storage unit 16 for storing various settings, a reception VR unit 17 for adjusting a reception volume reported from the parent speaker 12, and a call for adjusting a ringing tone from the handset 3. A sound VR unit 18, a parent CPU 19 that controls the entire parent device 1, a parent device communication unit 20 for communicating with the controller 2, and the like are provided. However, the volume set by the ringing tone VR unit 18 also acts on the adjustment of the calling voice when a voice call is made from the base unit 1 as will be described later.

  The controller 2 includes a controller communication unit 23 for processing a call signal of the connected slave unit 3 and connecting / disconnecting a communication path, a controller CPU 24 for controlling the entire controller, and the like.

  The handset 3 includes a call button 31 for calling the base unit 1, a handset speaker 32 and handset microphone 33 used for a call, a call unit 34 for controlling the handset speaker 32 and handset microphone 33, and the handset 3 as a whole. Is provided with a slave unit CPU 35 for controlling the slave unit, a slave unit communication unit 36 for communicating with the controller 2, and the like.

  The business intercom system configured as described above operates as follows. Hereinafter, it explains according to function. First, the operation when a call is made from the handset 3 will be described.

<Call from slave unit>
When a call button 31 of the child device 3 is pressed by a visitor or the like visiting the facility, the child device CPU 35 generates a call signal and transmits the call signal to the controller 2 via the child device communication unit 36. In the controller 2 that has received this call signal by the controller communication unit 23, the controller CPU 24 controls the controller communication unit 23 to transmit the call signal to both parent devices 1.
The both parent devices 1 that have received this calling signal by the parent device communication unit 20 display that the parent device CPU 19 has received a call from the child device 3 on the display unit 15. Then, a ringing tone is generated, and the calling unit 14 is controlled to make a sound from the parent speaker 12. However, this report sound is carried out at a volume set by the ringing tone VR unit 18. The ringing tone VR unit 18 can be operated in a standby state where the base unit 1 is not receiving a call and can be set in advance.

In response to this call, when a facility person operates the base unit 1 as a response, the base unit CPU 19 generates an operation signal and transmits it to the control unit 2 via the base unit call unit 20.
When the controller 2 receives this operation signal at the controller communication unit 23, the controller CPU 24 controls the controller communication unit 23 to transmit a speech path formation signal to the slave unit 3 and the master unit 2 that has responded. At the same time, the controller communication unit 23 is controlled to form a communication path in the controller.

  In the base unit 1 that has received the speech path formation signal, the base unit CPU 19 controls the communication unit 14 to form a speech path between the base unit microphone 13 and the base unit communication unit 20, and the base unit communication unit 20 and the base unit 1. A communication path between the machine speakers 12 is formed. In the handset 3 that has received the communication path forming signal, the handset CPU 35 controls the calling section 34 to form a communication path between the handset microphone 33 and the handset communication section 36, and the handset communication section 36. And a handset speaker 32 is formed. In this way, a communication path is formed between the slave unit 3 and the master unit 1 that has been subjected to the response operation, and a call can be made between the visitor and the facility personnel. The formed communication path is disconnected by operating the operation unit 11 of the base unit 1 to perform a predetermined end call operation.

<Direct call / call between base units>
The voice call (direct call) / call between the parent devices 1 is as follows. When the operation unit 11 of the base unit 1 is operated and the base unit 1 is selected and the direct sound call operation is performed, the base unit CPU 19 generates a call signal for direct call, and is controlled via the base unit communication unit 20. Transmit to machine 2.
In the controller 2 that has received the call signal by the controller communication unit 23, the controller CPU 24 controls the controller communication unit 23 to transmit the call signal to the callee master unit 1. At the same time, the controller communication unit 23 is controlled to form an intra-controller communication path for transmitting a transmission / reception voice signal between the caller master unit 1 and the callee master unit 1.

Upon receiving the call signal from the control unit 2 by the base unit communication unit 20, the callee base unit 1 displays that the base unit CPU 19 has received a direct call on the display unit 15 and controls the call unit 14. In order to report the voice signal transmitted from the caller base unit 1 from the base unit speaker 12, a communication path between the base unit communication unit 20 and the base unit speaker 12 is formed. Further, a communication path is formed between the parent microphone 13 and the parent communication unit 20 in order to transmit the response voice to the caller parent 1.
However, the volume of the call voice transmitted from the caller and reported by the callee parent machine speaker 12 can be adjusted by operating the reception VR unit 17 during the report.

On the other hand, the caller base unit CPU 19 forms a call path between the base unit microphone 12 and the base unit communication unit 20 in order to control the call unit 14 to transmit the calling voice, and to call the base unit 1 of the call destination. In order to report the response voice transmitted from the mobile phone, a communication path between the master communication unit 20 and the master speaker 12 is formed.
In this way, when a direct call is made, a call path is automatically formed, and the called party who receives the call can answer without operating the master unit 1 and can make a call with the caller. .

<Direct call / call between master units when direct sound is disabled>
Next, the operation when the direct call is prohibited will be described. By operating the master unit 1, it is possible to perform a direct sound prohibition setting that prohibits a direct call operation by voice. This setting can be set by a predetermined operation of the operation unit 11 of the base unit 1, and upon receiving this setting, the base unit CPU 19 does not perform the call control by voice even when a direct call is received, Make a call with. This setting is stored in the storage unit 15, and the direct sound prohibition setting is maintained until the setting is canceled.

  The operation in the case where a direct call is performed on the master unit 1 for which the direct sound prohibition is set is as follows. When a direct call is made from another master unit 1, a call signal is transmitted to the controller 2. In the controller 2 that has received the call signal by the controller communication unit 23, the controller CPU 24 transmits the call signal to the callee master unit 1 via the controller communication unit 23. At the same time, the controller communication unit 23 is controlled to form a communication path within the controller for transmitting a transmission / reception voice signal between the caller master unit 1 and the callee master unit 1.

Upon receiving the call signal, the callee master unit 1 displays that the master unit CPU 19 has received the call on the display unit 15, and controls the call unit 14 to generate the ring tone generated by the master unit CPU 19. 12 will sound.
The base unit CPU 19 transmits the generated ringing tone to the base unit 1 that is the calling source, and forms a communication path between the base unit microphone 13 and the base unit communication unit 20. However, since direct sound prohibition is set, a communication path between the base unit communication unit 20 and the base unit speaker 12 is not formed. As a result, the caller's voice is not reported and a ringing tone is reported instead. Note that the ringing tone when the direct tone prohibition setting is set may be reported at a volume according to the setting of the ringing tone VR unit 18.

  On the other hand, the caller base unit CPU 19 controls the call unit 14 to form a call path between the base unit microphone 13 and the base unit communication unit 20 and between the base unit communication unit 20 and the base unit speaker 12. Form a call path. Then, the ringing sound transmitted from the callee base unit 1 immediately after is reported from the base unit speaker 12.

  Thereafter, when the operation unit 11 of the callee base unit 1 is subjected to a predetermined response operation, the base unit CPU 19 ends the ringing tone generation, generates a response signal, and sends the response signal to the control unit 2 via the base unit communication unit 20. To transmit. Then, the communication unit 14 is controlled to maintain the communication path between the formed parent microphone 13 and the parent communication unit 20, and to report the caller's voice, the parent communication unit 20 and the parent speaker. A communication path between 12 is formed.

In the controller 2 that has received the response signal, the controller CPU 24 controls the controller communication unit 23 to transmit the response signal to the caller base unit 1. At the same time, the controller communication unit 23 is controlled to form a communication path within the controller for transmitting a transmission / reception voice signal between the caller master unit 1 and the callee master unit 1.
Then, in the caller base unit 1 that has received the response signal from the control unit 2, the base unit CPU 19 forms a communication path between the base unit microphone 13 and the base unit communication unit 20, and the base unit communication unit 20 and the base unit A communication path between the machine speakers 12 is formed. As a result, a call path is formed between the parent devices 1 and 1, and a call can be made. When the direct sound prohibition is set, a call can be made by performing a response operation.

In this way, it is possible to report the ringing tone without reporting the ringing voice transmitted from the caller even when the direct call is received. Therefore, it is possible to eliminate unnecessary noise when responding to a visitor or during a meeting, and it is possible to proceed smoothly such as the reception of a visitor. Further, even if the call voice is not reported, it is possible to easily recognize that the call has been received because the ring tone sounds.
In addition, when a direct call is made to the master unit 1 set to be prohibited from direct tone, since the ring tone is transmitted to the caller, the caller can be notified that the direct call prohibition is set. . Therefore, the call operator can recognize that it is useless to speak until a response operation is performed, which is convenient.

<Direct call / call between base units when the direct response function is stopped>
By operating the master unit 1, it is possible to perform a direct tone response function stop setting that does not cause the master microphone 13 to function when calling directly. This can be set by operating the operation unit 11 of the base unit 1 to stop a predetermined tone direct response function. Upon receiving this setting, the base unit CPU 19 communicates with the base unit microphone 13 from the base unit microphone 13 even when receiving the tone direct call. The communication path to the unit 20 is not formed. The direct sound response function can be stopped in the same manner by simply muting the parent microphone 13 and any control can be performed. This setting is stored in the storage unit 16 and is maintained until the determination is canceled.

  This will be specifically described below. When a direct call is made from another master unit 1 to the master unit 1 for which the direct tone response function stop setting has been made, a call signal is transmitted to the controller 2. In the controller 2 that has received the call signal, the controller CPU 24 controls the controller communication unit 23 to transmit the call signal to the callee master unit 1. At the same time, a communication path in the control unit for transmitting a transmission / reception voice signal between the caller base unit 1 and the callee base unit 1 is formed.

Upon receiving the call signal from the controller 2, the callee master unit 1 displays the call on the display unit 15 by the master unit CPU 19 and controls the call unit 14 to report the caller's voice. A communication path between the communication unit 20 and the parent speaker 12 is formed. However, base unit CPU 19 recognizes from the stored information in storage unit 16 that it is in the direct response function stop state, and does not form a communication path between base unit microphone 13 and base unit communication unit 20.
On the other hand, the caller base unit CPU 19 controls the call unit 14 (although no audio signal is transmitted from the callee base unit 1), a call path is formed between the base unit communication unit 20 and the base unit speaker 12. At the same time, a communication path between the parent microphone 13 and the parent communication unit 20 is formed in order to transmit the caller's voice.

Thus, a transmission path is formed from the caller base unit 1 to the callee base unit 1, and the caller's call voice is reported by the callee base unit 1. However, when the direct response function is stopped, the caller's voice reported from the master speaker 12 is reported at a low volume set by the ring tone VR unit 18 under the control of the master CPU 19.
In response to this call, when the called party performs a predetermined response operation on the operation unit 11 of the base unit 1 on which the direct call operation has been performed, the base unit CPU 19 generates an operation signal and the control unit 2 via the base unit communication unit 20. Transmit to. At the same time, the direct response function stop is canceled and the base unit microphone 13 is activated, and the communication unit 14 is controlled to form a communication path between the base unit microphone 13 and the base unit communication unit 20. As a result, a call path is formed between the parent devices, and a call can be made.

Thus, when the tone direct response function is stopped, the volume of the tone direct call can be reduced in conjunction with it. Therefore, if the conversation is set so that it does not leak even when a call is received, the alert sound of the calling voice can be reduced, and the situation where the conversation is disturbed can be eliminated. Therefore, it is possible to proceed smoothly such as reception of visitors.
Further, the volume of the ringing voice by direct call can be adjusted by the ringing tone VR unit 18 that adjusts the volume level of the ringing sound from the handset 3, and can be set in advance. Therefore, the volume can be adjusted to a small volume in advance, and it is possible to prevent a situation in which adjustment is performed in a hurry after receiving a call. Further, there is no need to separately provide a means for adjusting the volume of the calling voice.

In the above embodiment, the system is constituted by two master units 1, but the minimum number is two, and two or more master units 1 are connected to constitute the business intercom system of the present invention. The A plurality of slave units 3 may also be installed.
Further, the setting value of the ring tone VR unit 18 is made active when the direct sound response function is stopped, and the call voice is configured to decrease in conjunction with the direct sound response function only, but the normal sound response function is not stopped. The set value of the ring tone VR unit 18 may be applied even when the direct call is made.
