  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 intercom system according to the present invention. In FIG. 1, reference numeral 1 denotes an interphone handset (hereinafter simply referred to as a handset) that is installed at a front door or the like so that visitors can call residents. Reference numeral 2 denotes an interphone master unit (hereinafter simply referred to as a master unit) that is installed in the dwelling unit and responds to calls. Reference numeral 3 denotes an electric lock installed on the entrance door.

  The subunit | mobile_unit 1 has the camera 11 for imaging a visitor, the modulation | alteration part 12 which modulates the imaged video signal, the microphone 13 for talking with the main | base station 2, and the sound part 15 to which the speaker 14 was connected, the resident A call button 16 for calling, an ID input unit 17, and a slave unit interface (slave unit IF) 18 for connecting to the master unit 2 via the transmission line L1.

  The base unit 2 is connected to the base unit interface (base unit IF) 21 for connecting the base unit 1 and the electric lock 3 via the transmission line L2, and a CPU for controlling the base unit 2 (hereinafter referred to as a base unit CPU). 22), an unlock button 23 for unlocking the electric lock 3, a child lock button 24 as a control restricting means for invalidating the operation of the unlock button 23, and ID data for recognizing the returnee are stored. An ID data storage unit 25, an ID collation unit 26 for collating the ID data input from the ID input unit 17 and the ID data of the ID data storage unit 25, a microphone 27 and a speaker 28 for calling the handset 1 are connected. An audio unit 29, a call button 30 for calling with a visitor, a demodulation unit 31 for demodulating the modulated video signal, and a monitor 32 for outputting the demodulated video signal are provided. The call button 30 has a function of an end button during a call, and also serves as an end button.

The operation of the intercom system configured as described above will be described below. FIG. 2 shows a flow of system operation when a visitor's call operation is performed, and will be described based on this figure. A state where the child lock button is pressed will be described as a control restriction state, and a state where the child lock button is not locked will be described as a normal state.
When a visitor presses the call button of the slave unit 1 (S1), the camera 11 starts imaging (S2), and the captured video signal is modulated by the modulation unit 12 and passed through the slave unit IF 18 and the transmission line L1. Sent to the main unit 2. The base unit 2 demodulates the video signal transmitted via the base unit IF 21 by the demodulator 31 and displays the image on the monitor 32 under the control of the base unit CPU 22 in a normal state (S4). In addition, a ringing tone is reported from the speaker 28 (S5), and a call confirmation tone is reported in the handset 1. However, in the control restricted state (S3), a call confirmation sound is reported from the slave unit 1, but the master unit CPU 22 does not perform the control to display the image on the monitor 32 and the ring tone is emitted from the speaker 28. No control is performed.

  Thereafter, the process proceeds to the first process A (S6). When the unlocking button 23 is pressed by the resident in the normal state where the ringing sound is generated (S101), the unlocking process (S103) of the electric lock 3 is performed under the control of the master CPU 22. In addition, when the call button 30 is pressed (S104), a call path is formed with the handset 1, and a call can be made with a visitor. Thus, the resident can respond to the visitor's call while viewing the visitor video displayed on the monitor 32 (S7). On the other hand, in the control restricted state (S102), the unlocking process is not performed even if the unlock button 23 is pressed, but a call can be made with the visitor by operating the call button 30 (S104) (S7).

  Then, in this call or in a state where the call is possible, the process proceeds to the second process A (S8). When the unlock button 23 is operated, the unlock process is performed in the normal state in the same manner as in the call (S103). When in the restricted state (S102), the unlocking process is not performed. Thereafter, when the call button 30 is pressed (S104), the main unit CPU 22 determines that the end button has been pressed (S9), and controls the end of the call regardless of whether it is in the normal state or the control restriction state. Block the communication path with 1. As a result, the image output on the monitor 32 is finished (S10), the camera 11 is stopped, and the standby state is entered (S11).

As described above, when the child lock button as the control restricting means is provided and is turned on, the unlock button is locked and the electric lock cannot be unlocked even if the unlock button is operated. Therefore, it can be set so that it cannot be unlocked when there is a visitor when only a child is present, and security can be improved.
Further, in the child lock state, the ringing tone is not sounded and the monitor is not activated in the parent device, so that the child does not panic or feel uneasy.

  In the above-described embodiment, the monitor 32 is not operated when in the control restricted state, but the monitor 32 may be operated to display a visitor video. Further, when the monitor 32 is operated, a ringing tone may be generated. Further, in the control restricted state, a call can be made between the parent device 2 and the child device 1, but the operation of the entire parent device 2 may be stopped by restricting the call.

Next, a case where a resident who has gone out returns home will be described. When the intercom system is in the control restricted state, the returnee first inputs ID information from the ID input unit 17. The ID input unit 17 includes, for example, a fingerprint information input unit, and fingerprint information is input by pressing a finger against a predetermined unit. The ID input is a voice input unit when the ID collation unit 26 performs voice recognition, and a camera that captures a face when the face identification is performed. Moreover, the structure which only inputs a PIN code may be sufficient.
By the input of this ID information, it is compared with the ID information (fingerprint information) registered in the ID collation unit 26 of the base unit 2, and if there is the same information (if the fingerprints match), the authentication signal is sent to the base unit 2 The master unit CPU 22 cancels the control restriction state. That is, the child lock is released. At the same time, the master CPU 22 controls the unlocking of the electric lock 3. Thus, the returnee can open the unlocked entrance door and enter the dwelling unit by inputting the ID information.

  In this way, the child lock is released by inputting the ID information registered at the entrance, and the electric lock is also unlocked. Therefore, even when in the child lock state, the operation when returning home is simple.

  Here, when the input ID information is authenticated, the child lock is released and the electric lock 3 is also unlocked. However, the child lock may only be released. In this case, the child device 1 may be operated to call and cancel the child, or the returnee may cancel it.

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