Even if a situation in which a response operation cannot be performed occurs, it is possible to make a call with a visitor or the like, and to report an emergency situation.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments of the invention will be described in detail with reference to the drawings. FIG. 1 shows a block diagram of an intercom apparatus according to the present invention, in which an interphone slave unit (hereinafter simply referred to as a slave unit) 1 installed at a front door or the like and an interphone master unit (hereinafter simply referred to as a master unit) installed in a living room. 2), and the base unit 2 is connected to an emergency notification device 3 that outputs an emergency signal for notifying the occurrence of fire or earthquake occurrence information.

  The subunit | mobile_unit 1 communicates with the main | base station 2, the microphone 5 and the speaker 6 for calling with the main | base station 2, the sound part 7 which controls this microphone 5 and the speaker 6, the call button 8 which carries out the calling operation of the main | base station 2, and Interface (slave IF) 9 is provided. On the other hand, the base unit 2 includes an interface (base unit IF) 11 for communicating with the handset 1, a microphone 12 and a speaker 13 for calling with the handset 1, and an acoustic unit for controlling the microphone 12 and the speaker 13. 14, an alarm display unit 15 for displaying an alarm report, a call button 16 for responding to a call, a recovery button 17 for stopping the alarm report operation, and an emergency signal input unit for connecting the emergency report device 3 18 and a master unit CPU 19 for controlling the master unit 2.

The intercom apparatus configured as described above operates as follows. FIG. 2 is a flowchart showing the flow of the operation, which will be described based on this flow. First, when the emergency call device 3 outputs an emergency signal notifying the occurrence of an emergency in response to the occurrence of a fire or an earthquake, this signal is input to the emergency signal input unit 18 of the base unit 2 (S1). The master CPU 19 receives the emergency signal and issues a warning sound from the speaker 13 of the master 2 (S2) and causes the warning display unit 15 to display. Further, an alarm signal is transmitted to the slave unit 1, and a warning sound is also issued (S2) in the slave unit 1.
The alarm display unit 15 may display the occurrence of an emergency by lighting / flashing when the alarm display unit 15 is composed of light emitting means such as an LED. The content of the alarm may be displayed using characters.

  When the call button 8 of the handset 1 is pressed during the alarm issuance (S3), a call signal is sent to the main unit 2, but since the alarm is being issued (S4), the call signal is received. After the base unit CPU 19 reports the ringing sound from the speaker 13, the two-way communication path is formed (S5). At the same time, the volume of the alarm is reduced (S6) and the sensitivity of the microphone 12 is increased. In this way, a call can be made between the child device 1 and the parent device 2, that is, between a visitor and a resident who is not near the parent device 2.

  This state where the two-way communication path is formed is continued until the recovery button 17 is pressed (S7). When the recovery button 17 is pressed, the alarm notification of the master unit 2 and the slave unit 1 is stopped (S8), and at the same time, the two-way communication path is disconnected (S13), and the standby state is restored.

  On the other hand, when the call button 8 of the handset 1 is pressed in a state where no alarm is being issued, that is, in a normal state where no emergency signal is input (S3), the base unit CPU 19 reports a ringing sound from the speaker 13, A one-way communication path capable of only transmitting from the child device 1 to the parent device 2 is formed (S9). In this way, the sound input from the microphone 5 of the child device 1 can be output from the speaker 13 of the parent device 2.

Then, when the call button 16 of the parent device 2 is pressed in a state where this one-way communication path is formed (S10), the parent CPU 19 forms a two-way communication path (S11) and is input from the child device 1. The voice of the resident input from the microphone 12 of the master unit 2 is output from the speaker 6 of the slave unit 1 in addition to the voice of the visitor being output from the master unit 2. If the call button 16 is not pressed (S10), the state where the one-way communication path is formed is continued.
The state in which the two-way communication path is formed is terminated when an end-of-call operation such as re-operation of the call button 16 is performed (S12), and the communication path is disconnected (S13) and the standby state is restored.

As described above, during the alarm issuance, a call path is formed with the interphone master unit simply by performing a call operation from the interphone slave unit, so that the resident cannot respond to a call from the interphone slave unit due to an earthquake or the like. Even if the situation occurs, it is possible to make a call with a visitor and to report an emergency situation.
In addition, even if the two-way call state is entered, pressing the recovery button disconnects the call path, so that privacy can be maintained.
Furthermore, since the alarm sound that is issued becomes smaller when a two-way communication path is formed, it becomes easier to hear the voice of the call, and the call button operator and the resident are formed by the change of the alarm sound. I can recognize that. At this time, the microphone sensitivity of the interphone master unit increases, so that even if the resident is not near the interphone master unit, the resident's response voice can be reported well from the interphone slave unit, and smooth. Calls can be made.

  In the above embodiment, the alarm issuing operation of the master unit 2 and the slave unit 1 is stopped by the restoration operation. However, only the alarm sound may be stopped and the emergency display on the alarm display unit 15 may be continued. Further, in a normal state where no emergency signal is input, a call can be transmitted from the slave unit 1 by a call operation. However, a configuration may be adopted in which a call path is not formed only by a call operation.

It is a block diagram which shows an example of embodiment of the intercom apparatus which concerns on this invention. It is a flowchart which shows operation | movement of the intercom apparatus of FIG.
