8 is a flowchart for explaining a remote control method of a home automation system according to a first embodiment of the present invention.

Referring to FIG. 8, when the subscriber of a home in which the home automation system 100 is constructed selects the outing mode of the input means (not shown) of the home automation system 100 to go out, the home automation The server 180 sets the outing mode (S 1).

At this time, the subscriber sets the telephone number information of the wired / wireless terminals 500 and 300 to control the functions of the home automation system 100 from the outside by using the input means, and the wireless telephone number of the wireless terminal 300. When setting the information, the short service mode or the voice service mode is set.

When the visitor visits the home and selects a doorbell (not shown) of the door phone 110 (S 2), the visitor transmits a visit signal, a video signal and an audio signal of the visitor to the wireless connection unit 140 ( S 3).

The central control unit 145 of the wireless connection unit 140 checks whether the outing mode is set in the home automation system 100, and if the outing mode is not set, a door bell informing the subscriber in the home that there is a visitor. Outputs

If the outing mode is set, the central control unit 145 checks whether the telephone number information stored in the memory 141 is a wired telephone number (S4).

If the telephone number information stored in the memory 141 is a fixed telephone number, the central control unit 145 generates a call request signal using the stored fixed telephone number information as a receiving telephone number and generates a call request signal through the PSTN connection unit 160. Transfer to (S 5).

When the call request signal is received from the home automation system 100, the telephone station 400 determines the receiving wired terminal 500 and sets a call path through the wired terminal 500 and the PSTN 410 (S 6). .

In addition, the central control unit 145 of the wireless connection unit 140 transmits the voice signal of the visitor transmitted from the door phone 110 to the wired terminal 500 (S 7).
