In the mobile phone number table storage unit 31, information in which the phone number of the first mobile phone M1 carried by the resident is associated with the phone number of the second mobile phone M2 carried by the visitor H is the ID of the main room 2 When the number information of the second mobile phone M2 is registered from the in-room base 2 and registered with the information, the call control of the associated first mobile phone M1 is performed. Then, when receiving the response operation, control of formation of a communication path for enabling transmission and reception of audio and video between the base room 2 and the first mobile phone M1 via the server 3 is performed.

  Although registration with the server 3 is carried out by using a telephone number, control of communication path formation by the server 3 is carried out by using an IP address obtained by the server 3 inquiring of a telephone number management server (not shown). Further, in the mobile phone number table storage unit 31, the ID of the base unit 2 is linked to the phone number of the first mobile phone M1 in advance and registered, and the phone number registration of the second mobile phone M2 is The resident operates the first mobile phone M1 or the like. In addition, in the mobile phone number table storage unit 31 of the server 3, information on a plurality of dwelling units is collectively managed.

For example, a smartphone is used as the first mobile phone M1 and the second mobile phone M2. In this case, predetermined application software for communicating with the server 3 is installed in the first mobile phone M1, so that communication with the room parent device 2 via the server 3 becomes possible, and the intercom device is absent. It becomes the structure provided with the absence setting button set to mode, the unlocking button etc. which unlocks the electric lock 4 of the entrance door D1.
Further, it is assumed that the second mobile phone M2 has a short distance communication function of performing communication with the short distance communication unit 14 of the entry slave unit 1.

The intercom system configured in this way operates as follows. However, since the operation of receiving a call from the front door slave 1 and responding in the room parent unit 2 is the same as in the prior art, the description will be omitted, and the operation of responding with the first mobile phone M1 carried by the resident will be described. .
When the intercom device is set in the absence mode and the short-distance communication unit 14 of the entry slave 1 is in the on state, the short distance communication unit (not shown) of the second mobile phone M2 carried by the visitor H is activated. In this state, when the entrance slave unit 1 is called, it is transmitted to the entrance handset 1 by Bluetooth (registered trademark), for example. The telephone number information of the second mobile phone M2 read in this way is transmitted to the main room 2 under the control of the handset CPU 15.
In the room parent device 2 to which the telephone number information has been transmitted, the telephone number information is notified (sent) to the server 3 on the cloud C under the control of the parent device CPU 26, and waits for a response from the server 3. In addition, the information on the room parent device ID is also transmitted to the telephone number information transmitted to the server 3.

In server 3 having received the telephone number information of the second mobile phone M2, the server CPU 32 refers to the mobile phone number table storage unit 31, and the first mobile phone M1 associated with the received second mobile phone M2 If there is a corresponding telephone number, the first mobile phone M1 is called.
When the person carrying the first mobile phone M1 called in this way (the resident of the visiting destination) performs a response operation, a response signal is transmitted to the server 3, and the server CPU 32 having received the response signal sends In response to this, a permission signal is transmitted to secure a communication path between the first mobile phone M1 and the living room base unit 2.

On the other hand, in the main room 2 that has received the permission signal from the server 3, the communication path is extended to the front door slave 1 by the control of the main CPU 26. As a result, a communication path between the front door slave 1 and the first mobile phone M1 is formed. Further, the main unit CPU 26 that has received the permission signal further starts the camera 11 of the front door slave unit 1 and transmits the captured video to the first mobile phone M1 through the formed communication path.
As a result, audio transmission / reception and video transmission / reception (here, transmission of video from the entrance handset 1 to the first mobile phone M1) becomes possible between the entrance handset 1 and the first mobile phone M1, and a visit is made. The video of the person H is displayed on the first mobile phone M1, and the resident can make a call while watching the video of the visitor H.

  If there is no first mobile phone M1 associated with the transmitted second mobile phone M2's phone number in the mobile phone number table storage unit 31 of the server 3, the server 3 ends the control at that time. . That is, when the second mobile phone M2 is hooked on the front door handset 1, the control ends. Also, even if the associated first mobile phone M1 is registered, it is different from the registered information if the information of the room parent device ID transmitted together with the telephone number information of the second mobile phone M2 is registered. The control is terminated at this point because they are residents of different units.

As a result of the call being made in this way, if it is determined that the resident is a person who should unlock the electric lock 4 of the front door D1, after confirming that the visitor is a specific person such as visiting nursing, etc. The unlocking operation is performed by the operation of the mobile phone M1. When the unlocking button (not shown) is displayed on the first mobile phone M1 by a predetermined operation and the unlocking operation is performed by the button operation, an unlocking signal is generated and the room is accessed through the server 3 It is sent to the base unit 2.
In the main room 2 of the room receiving the unlocking signal, the CPU 26 of the base unit performs the unlocking operation of the electric lock 4 of the front door D1, and the front door D1 is unlocked.

In this way, the visitor H can call the first mobile phone M1 of the resident from the front door handset 1 with a simple operation of turning the second mobile phone M2, and the resident who responds to this call is the first The front door is unlocked by operating the mobile phone M1. Therefore, even if the resident who invites the visitor is not in the room state, a specific visitor H such as a care purpose can get into the room and see the cared person with the consent of the family, and it is easy to care.
On the other hand, a resident who receives and responds to a call can be relieved by making a call, confirming a visitor, and then unlocking, which is preferable from the viewpoint of security.

However, the above-mentioned calling operation of sending the second mobile phone M2 to the front door handset 1 is premised on the fact that the visitor H recognizes in advance that the intercom device of the visited residence is in the absent mode state, If it is not recognized that the absence mode is set, it is as follows.
The visitor H first presses the call button 13 as before, but in response to this operation, the base CPU 26 in the absent mode causes the speaker 12b of the front door handset 1 to sound a preset message voice. . For example, the message "Please forgive your smartphone" will be sounded.

  When this message is received and the mobile phone carried by the visitor H (second mobile phone M2) is taken over by the entrance handset 1, the short distance communication unit 14 receives the telephone number information. , It is transmitted to the main room 2 under the control of the slave CPU 15. The subsequent operation is the same as the above-described flow, and a call can be made with the resident.

Further, after the front door D1 is unlocked by the operation of the first mobile phone M1, the server 3 continues to perform the following control.
At the same time as the communication path formed between the first mobile phone M1 and the front door slave unit 1 is ended, the communication path between the indoor camera 5 and the first mobile phone M1 is formed.

Specifically, the server 3 that recognizes that the unlock signal is transmitted to the base room 2 is a switching signal for switching the communication path formed with the front door slave unit 1 to the indoor camera 5 in the room Transmit to base unit 2.
In the base unit 2 of the living room having received the switching signal, the base unit CPU 26 switches the communication path and activates the indoor camera 5. As a result, a communication path between the server 3 and the indoor camera 5 is formed, and the image captured by the camera 51 is transmitted to the server 3.
In addition, the server 3 maintains the communication path formed between the first mobile phone M1 and the room parent device 2, transmits the received video to the first mobile phone M1, and the first mobile phone M1. And establish a communication path between the camera and the indoor camera 5.
As a result, the resident can continue talking with the visitor who is in the room while watching the image captured by the indoor camera 5. Further, the condition of the care recipient can also be grasped by the captured image of the camera 51.

  Thus, the resident who is outing in response to the call can confirm the indoor condition by the captured image of the indoor camera 5 after inviting the specific visitor H into the room, and the visitor via the indoor camera 5 You can continue the call and feel relieved.

  In the above embodiment, the indoor camera 5 is provided with a call function so that calls can be continued with the visitor who entered the room through the indoor camera 5, but the indoor camera 5 has only the imaging function and has no call function. It is preferable that the resident who is out can grasp the situation simply by displaying the captured image of the indoor camera 5 on the first mobile phone M1.

In addition, when the indoor camera 5 does not have a call function, the second mobile phone carried by the visitor by the server 3 is performing communication between the first mobile phone M1 and the indoor camera 5 to obtain a captured image of the camera 51. Communication between mobile phone M2 and first mobile phone M1 may also be carried out, and the call with the visitor may be continued, and the resident who has unlocked the front door is the specific visitor who was invited into the room You can rest assured that you can continue talking with H.
Furthermore, in the above embodiment, although an external communication IF communicating with the server 3 is provided in the room parent machine 2 and the room parent machine 2 and the server 3 perform communication, this function is provided in the entrance child machine 1, The front door slave 1 and the server 3 may be communicated.
