On the other hand, when there is no key input in step S204, the controller 150 checks whether a call signal is received from the cavity door camera / interphone 136 (S248), and the call signal from the cavity door camera / interphone 136. If is received, the image of the visitor photographed through the cavity door camera / interphone 136 is displayed on the monitor 170, the voice of the visitor input through the cavity door camera / interphone 136 to the speaker 178 Output through (S260).

When the call signal is not input from the cavity door camera / interphone 136 in step S248, the controller 150 checks whether the call signal is input from the generation door camera / interphone 138 (S250).

When a call signal is input from the generation door camera / interphone 138, the controller 150 displays an image of the visitor photographed through the generation door camera / interphone 138 through the monitor 170, and generates the generation door camera / interphone 138. The visitor's voice input through the interphone 138 is output through the speaker 178 (S262).

On the other hand, the control unit 150 checks whether the call signal is input from the guard room terminal (not shown) connected to the guard room main unit 142 when the call signal is not input from the generation door camera / interphone 138 in step S250. (S252).

When the call signal is input from the guard room terminal, the controller 150 allows the guard to make a call between the guard and the user through the microphone 182 and the speaker 178 (264).

On the other hand, if the call signal is not input from the security terminal in step S252, the controller 150 checks whether the video providing signal from the common facility camera 140 is input (S254).

When the image providing signal is input from the common facilities camera 140, the controller 150 displays the image photographed by the common facilities camera 140 through the monitor 176 (S266).

On the other hand, the controller 150 controls the air pollution determination unit 114 to check the air pollution in the home when the image providing signal is not input from the common facilities camera 140. Thus, the air pollution determination unit 114 detects the pollution degree of the air in the home through the air quality measurement sensor 100, compares the detected pollution of the air with the pollution of the set air and provides the result to the controller 150. .

The controller 150 checks whether the detected degree of pollution of the air exceeds the set degree of contamination of the air (S268), and controls the intake motor driver 156 when the detected degree of pollution of the air exceeds the set degree of pollution of the air. While operating the intake motor 158. Here, the operating time of the intake motor 158 is preferably set to correspond to the pollution degree of the air. The intake fan (not shown) connected to the intake motor 158 inhales the outdoor air into the indoor (S270).

The controller 150 inhales the outdoor air into the room using the intake fan, and then controls the hood motor driver 160 to operate the hood motor 162 for a predetermined time. The hood motor (not shown) connected to the hood motor 162 allows the indoor air to be discharged to the outside (S282). Here, the operating time of the hood motor 162 is preferably set longer than the operating time of the intake motor 158.

On the other hand, the control unit 150 controls the gas detection unit 116 to check the leakage of the gas in the room when the detected contamination level of the air does not exceed the set pollution level of the air as a result of the determination in step S268. Thus, the gas detection unit 116 detects the amount of gas leaked into the room using the gas detection sensor 102 and provides it to the control unit 150.

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

Subsequently, the controller 150 generates a gas leak signal set to notify that the gas leaks to notify the guard room terminal connected to the guard room main device 142 or to control the telephone function unit 130 to dial a preset phone number ( S280).

Then, the controller 150 controls the hood motor driver 160 to operate the hood motor 162 for a predetermined time (S282). Thus, the hood fan connected to the hood motor 162 discharges the gas leaked in the room to the outside. 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, the controller 150 controls the temperature detector 122 to detect the temperature of the room when the amount of gas leaked into the room is less than the set gas amount as a result of the comparison in step S272. The temperature detector 122 detects the temperature of the room through the temperature sensor 112 and provides it to the controller 150.

The controller 150 compares the detected room temperature with the set temperature (S274), and outputs the set alarm sound through the speaker 178 when the detected room temperature 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 overheated."

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

Then, the controller 150 controls the hood motor driver 160 to operate the hood motor 162 for a predetermined time (S282). Accordingly, the hood fan connected to the hood motor 162 discharges the air that is overheated indoors to the outside. Here, the operation time of the hood motor 162 may be set to correspond to the temperature of the room.

On the other hand, the controller 150 checks whether the monitor 176 is set to the movement mode when the detected room temperature is lower than the set temperature as a result of the comparison in step S274 (S276).

When the monitor 150 is set to the monitor 176 moving mode, the controller 150 controls the human body position detecting unit 120 to detect the movement of the human body. Thus, the human body position detection unit 120 detects the movement of the human body using the human body detection sensors 1, 2, 3 (106, 108, 110), and generates a detection signal when the movement of the human body is detected to control it. To 150.

The controller 150 checks whether the detection signal provided by the human body position detection unit 120 is generated by the human body sensor 1 (106) (S298), and when the detection signal is generated by the human body sensor 1 (106). The monitor rotation motor driving unit 172 is controlled to rotate the monitor rotation motor 174 to the position of the set human body sensor 1 (106). Thus, the monitor 176 connected to the monitor rotation motor 174 is rotated to the position of the set human body sensor 1 (106) (S304). Here, the position of the set human body sensor 1 106 is when the monitor 176 is in front of the user.

As a result of the determination in step S298, the controller 150 checks whether or not the detection signal is generated by the human body sensor 2 (108) when it is not generated by the human body sensor 1 (106).

When the detection signal is generated by the human body sensor 2 (108), the controller 150 controls the monitor rotation motor drive unit 172 to rotate the monitor rotation motor 174 to the position of the set human body sensor 2 (108). Let's do it. Thus, the monitor 176 connected to the monitor rotation motor 174 is rotated to the position of the set human body sensor 2 (108) (S306). Here, the position of the human body sensor 2 (108) is set when the user is on the left side of the monitor 176 when the screen of the monitor 176 is viewed based on the direction toward the user.

On the other hand, the controller 150 checks whether the detection signal is generated by the human body sensor 3 (110) when the detection signal is not generated by the human body sensor 2 (108) (S302).

When the detection signal is generated by the human body sensor 3 110, the controller 150 controls the monitor rotation motor driver 172 to rotate the monitor rotation motor 174 to the position of the set human body sensor 3 110. Let's do it. Thus, the monitor 176 connected to the monitor rotation motor 174 is rotated to the position of the set human body sensor 3 (110) (S308). Here, the position of the set human body sensor 3 (110) is a case where the user is on the right side of the monitor 176 when the screen of the monitor 176 is viewed based on the direction toward the user.

On the other hand, the control unit 150 checks whether an RF signal is received from the RF transmitter 186 to the RF receiver 184 when the monitor 176 is not set to the moving mode as a result of the determination in step S276 (S284). . Here, the reception of the RF signal from the RF transmitter 186 may occur when an emergency occurs in the home. The emergency situation in the home may be any one of an intruder in the home, an emergency patient, and 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 frequency of reception of the RF signal for a set time. Here, the progress of the set time is made through the timer 188, the check of the frequency of reception of the RF signal for the set time is made through the counter 190.

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

On the other hand, if the reception of the RF signal is not one time within the set time, the controller 150 checks whether the RF signal is received twice (S288), and the reception of the RF signal is twice. Generates a guard room call signal to the guard room terminal connected to the guard station main unit 142 (S294).

As a result of the determination in step S288, the controller 150 checks whether the RF signal is received three times when the reception of the RF signal is not two times within the set time (S290), and when the reception of the RF signal is three times, The function unit 130 is controlled to call '119' or dial the set phone number (S296).
