This signal, to which the master unit address specifying the master unit 2 is added, is transmitted from the slave unit I / F 18 to the master unit I / F 28 of the interphone master unit 2 via the general-purpose network 5.

  The base unit CPU 27 of the intercom base unit 2 adds the base unit address added to the calling signal received via the base unit I / F 28 in the same manner as the base unit address assigned to the base unit. It is detected that there is a call from a visitor outside the dwelling unit (dwelling unit entrance) where the call operation is performed on the intercom slave unit 1 corresponding to the address of the slave unit, and a ringing tone or voice message to that effect is detected. The call can be notified by outputting from the machine speaker 25. The base unit CPU 27 activates the display unit 22 and the base unit video processing unit 23. By this control, the base unit video processing unit 23 sends the video signal received via the base unit I / F 28 to the display unit 22 by performing FM demodulation, signal amplification, etc., for example. (Video signal) can be displayed on the display unit 22, and the display unit 22 can also display (call display) a character message or picture data indicating that there is a call from a visitor. .

  Thereafter, when a resident in the dwelling unit who has confirmed the above-described call notification (call display) and video display performs a response operation using the call operation unit 20 of the interphone master unit 2, the parent who has detected this operation is detected. The machine CPU 27 activates the parent machine voice processing unit 26 to form a signal transmission path between the parent machine microphone 24 and the parent machine speaker 25 and the parent machine I / F 28 via the parent machine voice processing unit. For example, a response signal is generated by adding a self-base unit address and a slave unit address designating the interphone slave unit 1 in a SIP compatible signal format. The response signal generated by the base unit CPU 27 is transmitted to the handset I / F 18 of the intercom handset 1 via a signal transmission path opposite to the call signal described above.

  The slave unit CPU 17 of the intercom slave unit 1 adds the slave unit address in the same manner because the slave unit address added to the response signal received via the slave unit I / F 18 matches the slave unit address assigned to the slave unit. It is detected that there has been a response operation by a resident in the dwelling unit that has performed a response operation on the interphone master unit 2 corresponding to the master unit address that has been set, and the slave unit voice processing unit 15 is activated to By forming a signal transmission path between the handset speaker 14 and the handset I / F 18 via the handset voice processing unit, the handset microphone 13 and the handset speaker 14 used by the visitor are in the room.

It is to be noted that during this call, the room occupant can make a call while checking the video (video signal) of the visitor displayed on the display unit 22.

  In addition, according to the occupants, the unlocking operation unit 21 of the intercom master unit 2 is used for unlocking a visitor who is outside the dwelling unit (the entrance to the dwelling unit) during the call as described above. It can be performed. The master CPU 27 that has detected this operation adds, for example, an electric lock / unlock code, its own master device address, and a slave device address designating the interphone slave device 1 as the operation information. An unlocking activation control signal is generated. Further, the unlocking activation control signal generated by the master CPU 28 is transmitted to the slave I / F 18 of the interphone slave 1 via the same signal transmission path as the response signal described above.

  The handset CPU 17 of the intercom handset 1 just matches the handset address added to the unlocking activation control signal received via the handset I / F 18 with the handset address assigned to the handset. The operation information that is added in the same manner, for example, the electric lock unlocking code matches the electric unlocking code predetermined for unlocking the electric lock 3, so that the operation information is valid. Judge that there is. The slave CPU 17 generates a controller control signal in a signal format compatible with, for example, SIP, to which the controller address for designating the electric lock controller 4 and the slave ID are read out from the slave storage unit 16. The controller control signal generated by the slave CPU 17 is transmitted from the slave I / F 18 via the general-purpose network 5 and is received as a valid signal by the electric lock controller 4 having the same controller address. become.

  Here, the electric lock controller 4 is controlled by a controller control signal transmitted via the intercom handset 1 based on the unlocking operation by the interphone master unit 2, and generates an electric lock unlocking signal to generate the electric lock signal. By sending it out to the lock 3, the electric lock can be unlocked safely without causing malfunction or mischief. Therefore, a visitor outside the dwelling unit (dwelling unit entrance) can enter the dwelling unit by opening the entrance door where the electric lock 3 is unlocked.

  In addition, according to the resident in the dwelling unit, for example, the timing after the unlocking operation for unlocking the electric lock 3 as described above is performed using the unlocking operation unit 21 of the intercom base unit 2. When the call end operation is performed using the call operation unit 20, the above-described call path is blocked and the call is ended by the control of the base unit CPU 27 that detects the operation and the handset unit CPU 17 of the intercom handset 1. it can.

  In addition, according to the above description, the timing when the unlocking operation unit 21 of the intercom master unit 2 uses the unlocking operation unit 21 during the occupancy in the dwelling unit is from a visitor outside the dwelling unit (dwelling unit entrance). However, the present invention is not limited to this timing. For example, when a call is not made from the interphone handset 1 to the interphone base unit 2 or when the occupant monitors the state of the outside of the dwelling unit during the same stand-by, the call operation unit 20 is operated to The same unlocking operation can be performed during monitor monitoring in which a communication path is formed.

  As is clear from the above description, according to the embodiment of the present invention, the electric lock controller 4 for locking and unlocking the electric lock 3 is installed in the dwelling unit separately from the interphone slave unit 1 and the interphone master unit 2 is installed. When the slave unit CPU 17 of the intercom slave unit 1 determines that the operation information transmitted from the master unit CPU 27 that has detected the unlocking operation by using the unlocking operation unit 21 is valid, the slave unit CPU 17 causes the slave unit CPU 17 to The electric lock controller 4 matching the identification number read from the storage unit 16 can be controlled. Thereby, since the electric lock controller 4 is controlled by the signal transmitted via the intercom handset 1, the electric lock 3 can be safely unlocked without causing malfunction or mischief.
