The central control unit 149 of the remote interface 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 informing the subscriber in the home that there is a visitor. Output the bell.

If the outing mode is set, the central control unit 149 checks whether the telephone number information stored in the memory 141 is a wired telephone number (S4).

If the phone number information stored in the memory 141 is a fixed telephone number, the central control unit 149 generates a wired call request signal using the stored fixed telephone number information as a receiving telephone number and transmits the PSTN 410 through the PSTN processing unit 146. (S5).

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

In addition, the central control unit 149 of the remote interface unit 140 transmits the voice signal of the visitor transmitted from the door phone processing unit 110 to the wired terminal 500 (S 7).

At this time, the central control unit 149 transmits a voice signal indicating that there is a visitor transmitted from the voice guide unit 142 before transmitting the visitor's voice signal to the wired terminal 500, thereby confirming that the subscriber has a visitor. It is desirable to be able to.

The subscriber checks the voice information indicating that there is a visitor output from the wired terminal 500 and the voice information of the visitor, and if there is voice information to be delivered to the visitor, the subscriber inputs it through the wired terminal 500.

The wired terminal 500 transmits a voice signal corresponding to the voice information input by the subscriber to the remote interface unit 140 through the set wired call path, and the central control unit 149 is received through the PSTN processing unit 146. The voice signal is transmitted to the voice processor 147.

The voice processing unit 147 decodes the voice signal and transmits the voice signal to the voice input / output unit 112 of the door phone processing unit 110, and the voice input / output unit 112 corresponds to the voice signal of the subscriber to be transmitted. The voice information is output so that the visitor can listen to the subscriber's voice information (S8).

On the other hand, if the wireless telephone number information is stored in the memory 141, the radio controller 149a checks whether the short service mode is set (S 9).

If the short service mode is set, the wireless control unit 149a receives the received radio telephone number information stored in the memory 141, and generates a short message using the stored short information.

The wireless controller 169a transmits the generated short message to the wireless communication network 210 through the wireless processor 143 (S 10).

In this case, the short information stored in the memory 141 may be stored as shown in Table 2 below.

Kinds Short content visitant There are visitors Fire occurs Abnormal overheat detected ˚ ˚

As described in Table 2, the subscriber or manufacturer can set and store the short content according to the situation that may occur in the home automation system 100 in the memory 141.

When the short message is transmitted through the wireless communication network 210, the wireless communication station 200 identifies the receiving wireless terminal 300 and transmits the received short message to the corresponding wireless terminal 300.

The remote controller 341 of the wireless terminal 300 provides an image display signal corresponding to the short content of the short message received through the wireless connection unit 350 to the image display unit 320, and the image display unit 320 The video information according to the video display signal, that is, the short content is displayed so that the subscriber can recognize the situation occurring at home.

On the other hand, when the voice service mode is set, the wireless controller 169a generates a wireless call request signal using the wireless telephone number information stored in the memory 141 as a received telephone number, and converts the generated wireless call request signal into a wireless processor. The wireless communication network 210 is transmitted to the wireless communication network 210 through step 143 (S 11).

In addition, the subscriber may confirm that there is a visitor through the guide voice information output from the wireless terminal 300, and may identify the visitor's identity through the displayed image information and the output visitor's voice information.

The subscriber listens to the visitor's voice information output through the transmitter / receiver unit 330 of the wireless terminal 300, and if there is voice information to be transmitted to the visitor, the subscriber inputs the voice information through the receiver / receiver unit 330.

The transmitter / receiver unit 330 transmits a voice signal corresponding to the voice information input by the subscriber to the remote controller 341, and the remote controller 341 transmits the voice signal of the subscriber to the home automation channel through the set wireless call path. And transmits to the remote interface 140 of the system 100.

The wireless controller 149a of the remote interface unit 140 transmits the voice signal of the subscriber received through the wireless processor 143 to the door phone processor 110 through the voice processor 147.

In addition, the voice input / output unit 112 of the door phone processing unit 110 outputs the subscriber's voice signal transmitted from the remote interface unit 140 so that the visitor can listen to the visitor and the subscriber. (S 14).

Thereafter, when the subscriber confirms the visitor's identity and wants to release the lock function of the door phone processing unit 110, the subscriber selects a specific key button preset in the wired terminal 500 or the wireless terminal 300.

Hereinafter, a case in which the subscriber controls the home automation system 100 remotely using the wireless terminal 300 will be described.

That is, when the subscriber selects a specific button key of the keypad 31 of the wireless terminal 300, the remote controller 341 transmits the number key signal corresponding to the received key signal to the home automation system 100 (S 15). ).

The wireless controller 149a of the home automation system 100 retrieves a control signal corresponding to the number key signal received through the wireless processor 143 from the memory 141.

That is, it is checked whether the number key signal transmitted from the wireless terminal 300 corresponds to a preset lock release signal, and if it is the same, it is checked whether the subscriber is authenticated (S16).

At this time, the authentication process of the subscriber using the wireless terminal 300 transmits the voice signal of the authentication state through the voice guide unit 142, the number key signal transmitted from the wireless terminal 300 is stored in the memory 141 It may be determined whether or not the same as the password signal, and if it is the same, it may be determined as an authenticated subscriber.

When the authentication process of the subscriber is correctly completed, the wireless controller 149a transmits a lock release signal to the lock processor 113 of the door phone processor 110.

When the lock release signal is received, the lock processing unit 113 releases the lock function to allow the visitor to enter and exit the home (S 17).

In this case, the wireless controller 169a may perform authentication processing of the subscriber, receive a number key signal, receive a number key signal corresponding to the unlock signal, and perform authentication processing of the subscriber.

That is, it is preferable to perform authentication processing of the subscriber before transmitting the lock release signal to the door phone processing unit 110.
