On the other hand, if the illuminance checked in the illuminance determiner 118 does not correspond to the set low illuminance in step S234, the controller 150 determines that the illuminance around the home automation system is high, and the low illuminance illuminator driver 164 The low illumination LED 166 is turned off at step S236 and the high illumination light LED 170 is turned off by controlling the high illumination light driving unit 168 at step S238.

If there is no key input in step S204, the control unit 150 checks whether a call signal is received from the common entrance camera / interphone 136 (S248). If the call signal is received from the common entrance camera / interphone 136, Interphone 136 is displayed on the monitor 170 and the voice of the visitor inputted through the common entrance camera / interphone 136 is displayed on the speaker 178 through the common entrance camera / (S260).

In step S250, the control unit 150 checks whether a call signal is inputted from the household entrance camera / interphone 138 when the call signal is not inputted from the common entrance camera / interphone 136 in step S248.

The control unit 150 displays the image of the visitor photographed through the household entrance camera / interphone 138 through the monitor 170 when the call signal is input from the entrance door camera / interphone 138, The voice of the visitor inputted through the interphone 138 is outputted through the speaker 178 (S262).

On the other hand, if it is determined in step S250 that the call signal is not input from the home entrance camera / interphone 138, the control unit 150 checks whether a call signal is input from a guard room terminal (not shown) connected to the guard room main body 142 (S252).

The control unit 150 makes a call between the security guard and the user via the microphone 182 and the speaker 178 through the guard room terminal when the call signal is input from the guard room terminal (264).

In step S254, the control unit 150 checks whether a video signal is input from the common facility camera 140 when the call signal is not input from the guard room terminal in step S252.

When the image providing signal is input from the public facility camera 140, the control unit 150 displays the image photographed by the public facility camera 140 through the monitor 176 (S266).

On the other hand, when the image providing signal is not inputted from the public facility camera 140, the control unit 150 controls the air pollution determination unit 114 to check whether air in the house is polluted. The air pollution judging unit 114 detects pollution degree of air in the house through the air quality measurement sensor 100, compares the pollution degree of the detected air with the pollution degree of the set air, and provides the result to the control unit 150 .

The control unit 150 checks whether the pollution degree of the detected air exceeds the pollution degree of the set air (S268). When the pollution degree of the detected air exceeds the pollution degree of the set air, the controller 150 controls the suction motor driving unit 156, Thereby causing the intake motor 158 to operate. Here, the operation time of the intake motor 158 is preferably set to correspond to the pollution degree of the air. An intake fan (not shown) connected to the intake motor 158 sucks the outdoor air into the room (S270).

The control unit 150 uses the intake fan to suck outdoor air into the room, and then controls the hood motor driving unit 160 to operate the hood motor 162 for a predetermined period of time. The hood motor (not shown) connected to the hood motor 162 discharges the indoor air to the outside (S282). Here, it is preferable that the operation time of the hood motor 162 is set longer than the operation time of the intake motor 158.

On the other hand, if it is determined in step S268 that the pollution degree of the detected air does not exceed the pollution degree of the set air, the control unit 150 controls the gas detection unit 116 to check the leakage of the gas in the room. The gas detection unit 116 detects the amount of gas leaking into the room by using the gas detection sensor 102 and provides the detected amount of gas to the control unit 150.

The control unit 150 compares the amount of gas leaked to the room with the set gas amount (S272), and outputs an alarm sound set when the amount of gas leaked to the room is greater than the set gas amount through the speaker 178 (S278) . Here, the alarm sound generated upon gas leakage may be a voice message such as " gas is leaking into the room ".

Then, the control unit 150 generates a gas leak signal to notify that the gas leakage occurs, informs the guard room terminal connected to the guard room main body 142, or controls the telephone function unit 130 to dial a preset telephone number S280).

Then, the control unit 150 controls the hood motor driving unit 160 to operate the hood motor 162 for a predetermined time (S282). Accordingly, the hood fan connected to the hood motor 162 discharges the gas leaking out to the room. Here, the operation time of the hood motor 162 may be set to correspond to the amount of gas leaked into the room.

On the other hand, if it is determined in step S272 that the amount of gas leaked into the room is smaller than the set amount of gas, the controller 150 controls the temperature detector 122 to detect the temperature of the room. The temperature detector 122 senses the temperature of the room through the temperature sensor 112 and provides the detected temperature to the controller 150.

The control unit 150 compares the sensed temperature of the room with the set temperature (S274), and outputs the alarm sound through the speaker 178 when the sensed temperature of the room exceeds the set temperature (S278). Here, the alarm sound generated when the temperature is overheated may be a voice message such as "the room is in an overheated state ".

Thereafter, the control unit 150 generates a set temperature overheating signal to notify the overheating of the room, and informs the guard room terminal connected to the guard room main unit 142 or controls the telephone function unit 130 to dial a preset telephone number (S280).

Then, the control unit 150 controls the hood motor driving unit 160 to operate the hood motor 162 for a predetermined time (S282). Thus, the hood fan connected to the hood motor 162 discharges the overheated air to the outside of the room. Here, the operation time of the hood motor 162 may be set to correspond to the temperature of the room.

On the other hand, if it is determined in step S274 that the sensed indoor temperature is lower than the predetermined temperature, the controller 150 determines whether the monitor 176 is set in the moving mode (S276).

The controller 150 controls the human body position sensing unit 120 to sense the movement of the human body when the monitor 176 is set in the movement mode. Accordingly, the human body position sensing unit 120 senses the human body movement using the human body sensing sensors 1, 2, and 3 (106, 108, and 110), generates a sensing signal when the human body is sensed, (150).

The control unit 150 checks whether the sensing signal provided by the human body position sensing unit 120 is generated by the human body sensing sensor 1 106. If the sensing signal is generated by the human body sensing sensor 106 And controls the monitor rotation motor drive unit 172 to rotate the monitor rotation motor 174 to the position of the set human body detection sensor 1 106. Accordingly, the monitor 176 connected to the monitor rotation motor 174 rotates to the position of the set human body detection sensor 106 (S304). Here, the position of the human body detection sensor 1 106 set is the case where the monitor 176 faces the user.

If it is determined in step S298 that the sensing signal is not generated by the first sensing sensor 106, the controller 150 determines whether the sensing signal is generated by the second sensing sensor 108 in step S300.

The control unit 150 controls the monitor rotation motor driving unit 172 to rotate the monitor rotation motor 174 to the position of the set human body detection sensor 108 when the detection signal is generated by the human body detection sensor 108 . Accordingly, the monitor 176 connected to the monitor rotation motor 174 rotates to the position of the set human body detection sensor 108 (S306). Here, the position of the set human body sensor 2 108 is the case where the user is on the left side of the monitor 176 when the screen of the monitor 176 is oriented toward the user.

On the other hand, if it is determined in step S300 that the sensing signal is not generated by the sensing sensor 2, the controller 150 determines whether the sensing signal is generated by the sensing sensor 3 (S302).

When the detection signal is generated by the human body detection sensor 3 110, the control unit 150 controls the monitor rotation motor driving unit 172 to rotate the monitor rotation motor 174 to the position of the human body detection sensor 3 110 . Accordingly, the monitor 176 connected to the monitor rotation motor 174 is rotated to the position of the set human body detection sensor 3 (S308). Here, the position of the set human body detection sensor 3 110 is the case where the user is located on the right side of the monitor 176 when the screen of the monitor 176 is oriented toward the user.

If it is determined in step S276 that the mode is not set to the monitor 176 moving mode, the controller 150 checks whether an RF signal has been received from the RF transmitter 186 to the RF receiver 184 (S284) . Here, the reception of the RF signal from the RF transmitter 186 may occur when an emergency situation occurs in the home. The emergency situation in the home may be either an intruder in the home, an emergency patient, or a fire in the home.

When the RF signal is received from the RF transmitter 186 to the RF receiver 184, the controller 150 checks the receipt frequency of the RF signal for a predetermined time. Here, the progress of the set time is performed through the timer 188, and the number of receipt of the RF signal is checked through the counter 190 during the set time.

That is, the controller 150 checks whether the RF signal has been received once for the set time (S286). If the RF signal is received once within the set time, the controller 150 transmits a preset voice message or emergency bell through the speaker 178 (S292).

On the other hand, if it is determined in step S286 that the reception of the RF signal is not one time, the controller 150 checks whether the reception of the RF signal is twice (S288). If the reception of the RF signal is two To the guard room terminal connected to the guard room master device 142 (S294).

If it is determined in step S288 that the RF signal is not received twice within the set time, the control unit 150 checks whether the RF signal is received three times (S290). If the RF signal is received three times, The control unit 130 controls the function unit 130 to call '119' or dial the set telephone number (S296).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.

As described above, according to the home automation system and the control method thereof according to the present invention, it is possible to solve difficulties in installation and inconvenience of use by integrating home automation devices distributed in the home.
