In S120, the entrance CPU 251 determines whether or not the call button 202 has been selected.
If the entrance CPU 251 determines in S120 that the call button 202 has not been selected, the entrance CPU 251 returns to S110 and continues displaying the call display.

On the other hand, if the entrance CPU 251 determines that the call button 202 is selected in S120, the entrance CPU 251 proceeds to S130.
In S <b> 130, the entrance CPU 251 calls the room base unit 10 corresponding to the room number selected by the room selection button 201 or the room number input by the numeric keypad 203. The calling is performed by transmitting a calling signal using, for example, an Internet communication network.

  In S140, the entrance CPU 251 determines whether or not there is a response to the call to the living room parent device 10 performed in S130. If it is determined that there is no response, the process of S140 is continued. That is, it waits for a response until there is a response from the living room master unit 10. However, if a call cancel button is displayed instead of the call button 202 during the call and the call cancel button is selected by a touch operation, the process of waiting for a response is stopped and the call process is terminated. May be.

On the other hand, if the entrance CPU 251 determines in S140 that there is a response to the call made to the in-room master unit 10 performed in S130, the process proceeds to S150.
In S150, the entrance CPU 251 determines whether or not a call is permitted from the living room master unit 10. Here, the call permission means that a call between the room master 10 and the entrance terminal 20 is permitted by selecting the response button 102 of the room master 10 in a response process described later.

  When the entrance CPU 251 determines in S150 that the call is permitted from the room base unit 10, the process proceeds to S160. If the call is not permitted, the entrance CPU 251 ends the call process.

  In S160, the entrance CPU 251 starts a call with the room base unit 10 that has responded, and when the call ends, the calling process ends. When a call starts here, the voice acquired by the base unit microphone 113 transmitted from the room base unit 10 is received, and the received voice is output using the entrance speaker 222. In addition, an image captured using the entrance camera 212 is transmitted to the living room base unit 10.

That is, the processes from S130 to S160 are processes corresponding to the function of the Internet telephone through the Internet.
<Response processing>
Next, a response process performed by the master CPU 141 using a communication application will be described with reference to FIG.

The response process is started when a call signal transmitted from the entrance terminal 20 is received.
In S210, base unit CPU 141 displays a predetermined incoming call display on base unit display screen 121.

The incoming call display here includes, for example, display of an entrance video display 101, a response button 102, a response rejection button 103, and an unlock button 104 as shown in FIG.
The entrance video display 101 is a part for displaying video captured by the entrance camera 212 transmitted from the entrance terminal 20. The entrance video display 101 is not limited to displaying the video imaged by the entrance camera 212, and may be a display such as an icon indicating that the incoming call is from the entrance.

The response button 102 is a button that responds to the entrance terminal 20 by a resident's touch operation and starts a call with the entrance terminal 20.
The response rejection button 103 is a button for rejecting a response to a call transmitted from the entrance terminal 20.

The unlock button 104 is a button for unlocking, specifically, a button for transmitting an unlock instruction to the entrance terminal 20.
In S220, base unit CPU 141 determines whether response button 102 has been selected or not.

When determining that the response button 102 has been selected in S220, the master CPU 141 proceeds to S230.
In S230, base unit CPU 141 starts a call process that is a process of making a call in response to entrance terminal 20.

Here, when the call process is started, for example, the screen display may change to a call display as shown in FIG.
Here, the call display includes display of an entrance video display 101, a disconnect button 105, and an unlock button 104.

Here, the disconnect button 105 is a button for ending the call and ending the response process.
The entrance video display 101 and the unlock button 104 may be the same as before the response button 102 is selected.

Note that the size and arrangement of the entrance video display 101 and the unlock button 104 displayed may be different from the incoming call display that is the display before the response button 102 is selected.
In S240, base unit CPU 141 determines whether or not unlocking is permitted by determining whether or not unlocking button 104 is selected.

When determining that unlocking is permitted in S240, base unit CPU 141 proceeds to S250.
In S250, base unit CPU 141 outputs an unlock command signal to entrance terminal 20.
The unlock command signal is a signal for causing the entrance terminal 20 to output an audio signal for unlocking.

On the other hand, when determining that unlocking is not permitted in S240, base unit CPU 141 proceeds to S260.
In S260, base unit CPU 141 determines whether disconnection of call is selected by determining whether disconnect button 105 is selected.

When determining in step S260 that disconnection of the call has been selected, base unit CPU 141 ends the call and ends the response process.
On the other hand, if it is determined in S260 that the call disconnect has not been selected, the process returns to S230, and the subsequent processes are performed. That is, the call process continues until the disconnect button 105 is selected.

Returning to S220, if the base CPU 141 determines that the response button 102 is not selected in S220, it shifts the process to S270.
In S270, base unit CPU 141 determines whether unlock button 104 has been selected or not. Note that whether or not the unlock button 104 has been selected is the same as the determination in S240.

  Similar to the determination in S240, if the master CPU 141 determines that the unlock button 104 has been selected, it outputs an unlock command signal to the entrance terminal 20 in S280, similar to S250. Then, base unit CPU 141 ends the response process.

On the other hand, if the parent CPU 141 determines that the unlock button 104 has not been selected, the process proceeds to S290.
In S290, base unit CPU 141 determines whether response rejection button 103 has been selected or not. When determining that the response rejection button 103 has been selected in S290, the master CPU 141 ends the response process.

On the other hand, if it is determined in S290 that the response rejection button 103 has not been selected, the master CPU 141 shifts the process to S220 and performs the subsequent processes.
As described above, the response process is the same as the Internet telephone using the communication application except that the unlock button 104 is displayed and the unlock command signal is output when the unlock button 104 is pressed. May be.

Note that S250 and S280 correspond to processing as a command output unit.
<Unlocking process>
Next, the unlocking process performed by the unlocking CPU 341 will be described with reference to FIG.

The unlocking process is started when the unlocking device 30 acquires an audio signal from the entrance terminal 20 using the earphone input unit 311.
In S310, the unlocking CPU 341 converts the acquired audio signal, which is an acquired audio signal, into a converted signal, which is a digital signal, as shown in FIG.

  In S320, the unlocking CPU 341 collates the converted signal converted in S310. Here, in the verification of the converted signal, for example, the acquired speech signal is output from the entrance terminal 20 by determining whether or not the waveform of the converted signal matches the waveform of the verification signal stored in the verification memory 331 in advance. This means that it is determined whether or not the audio signal is received.

As shown in FIG. 14, the verification signal is set in advance by converting the audio signal output from the entrance terminal 20 into a digital signal.
In S330, the unlocking CPU 341 determines whether or not the acquired audio signal is an audio signal output from the entrance terminal 20 by collating the converted signal in S320.

If the unlocking CPU 341 determines in S330 that the acquired audio signal is an audio signal output by the entrance terminal 20, the process proceeds to S340.
In S340, the unlocking CPU 341 outputs an unlocking signal and ends the unlocking process.

On the other hand, when the unlocking CPU 341 determines in S330 that the acquired audio signal is not an audio signal output by the entrance terminal 20, the process proceeds to S350.
In S350, the unlocking CPU 341 rejects the unlocking of the entrance door 40 and ends the unlocking process. Here, the unlocking refusal may be, for example, that an error sound is generated using the entrance speaker 222 without unlocking the entrance door 40.

  Note that the acquisition of the audio signal using the earphone input unit 311 that triggers the start of the unlocking process corresponds to the process as the audio acquisition unit, S320 and S330 correspond to the process as the audio determination unit, and S340 This corresponds to processing as a lock output unit.

<Registration application processing>
Next, registration application processing performed by the master CPU 141 using a communication application will be described with reference to FIG.

The registration application process is started when a registration application function preset on the communication application is executed.
In S410, base unit CPU 141 searches for an ID in accordance with an input by the user of living room base unit 10. Here, the ID refers to an ID on a communication application assigned to each entrance terminal 20. Further, the ID of the entrance terminal 20 is notified to the resident at the time of moving into a housing complex or contracting, for example.

In S420, base unit CPU 141 displays the terminal information of entrance terminal 20 that matches the ID searched in S410.
In S430, when the user of the living room base unit 10 selects the terminal information of the entrance terminal 20 displayed in S420, the base unit CPU 141 transmits a registration application to the entrance terminal 20.

<Registration approval process>
Next, registration approval processing performed by the entrance CPU 251 using a communication application will be described with reference to FIG.

The registration approval process is started when the communication application is executed.
In S510, the entrance CPU 251 acquires a registration application. The registration application here refers to a registration application transmitted from the room parent device 10 in S430 of the registration application process performed by the room parent device 10.
