The indoor sensor 410 measures at least one of the indoor radon concentration, the carbon dioxide concentration, the temperature sensor, and the humidity sensor installed at an arbitrary position in the indoor space, Consists of a radon sensor measuring the radon concentration.

The radon concentration absorbs the ion charge generated during the alpha decay in the radon gas contained in the air, analyzes the electric signal detected through the signal processing, and transmits the analyzed electric signal to the controller 500 in real time.

That is, the indoor sensor 410 measures the degree of pollution of indoor air and provides the measured degree of indoor air to the control unit 500 so that it is possible to determine whether or not the control unit 500 requires ventilation.

The outdoor sensor 420 is installed outdoors to measure the concentration of external dust. When the window 100 is opened for ventilation, the outdoor sensor 420 is installed in the filter unit 200 are operated.

That is, the outdoor sensor 420 detects dust included in the air, for example, and measures the degree of contamination. When the light output from the light emitting unit is detected by the light receiving unit to measure the concentration of the dust, It is possible to measure the amount of dust from the light amount information detected by the light receiving unit due to the pollutant and change the sensor to a sensor capable of measuring the known contamination degree.

That is, the control unit 500 measures the radon concentration using the electric signal detected by the indoor sensor 410, and compares the detected electric signal with the signal pattern information according to the previously stored external noise signal type And distinguishes the normal or abnormal alpha particle detection signal and counts the normal alpha particle detection signals distinguished during a predetermined measurement time to calculate a radon concentration value based on the count of the counted normal alpha particle detection signals.

Also, the control unit 500 compares the light amount information detected by the outdoor sensor 420 with the light amount information according to the stored concentration of the dust, and calculates the atmospheric dust concentration.

The control unit 500 compares the pollution degree of the indoor air, that is, the concentration of radon, with the preset reference value for window opening / closing determination, and if the detected concentration of the radon is greater than or equal to the window opening / And outputs an operation signal to the window driving unit 300 so that the window 100 is opened for air ventilation.

In addition, the controller 500 controls the opening of the window 100 so that the amount of ventilation can be adjusted according to the degree of contamination of the indoor air.

That is, if the degree of contamination of indoor air is a predetermined value, for example, 70% <contamination degree <100%, the window 100 is controlled to be 100% , And controls the window 100 to be opened by 30% if 10% <contamination degree <30%.

The control unit 500 detects the position of the window 100 using the position sensor 700 if the degree of contamination of the indoor air is less than the reference value for determining whether the window 100 is open, And outputs an operation signal to the window driving unit 300 so as to be in the closed state.

The control unit 500 compares the calculated contamination degree of the outdoor air, that is, the dust concentration, with a reference value for determining filter unit opening / closing, and if the detected concentration of the dust is equal to or greater than the filter unit opening / And outputs an ON signal to the actuator 130 to control the window 100 and the filter unit 200 to be adhered by a magnetic force.

If the concentration of the detected dust is lower than the reference value for judging opening / closing of the filter unit, the control unit 500 outputs an off signal of the actuator 130 to the window unit 100 and the filter unit 200 Thereby preventing the window 100 and the filter unit 200 from being separated from each other.

In addition, the controller 500 detects the position of the window 100 using the position sensor 700 and confirms whether the window 100 is opened or closed.

The switch input unit 600 receives an opening and closing operation signal of the window 100 from a user and pollution degree setting information to be set for opening and closing the window 100 and the filter unit 200 and outputs the pollution degree setting information to the control unit 500 , A keypad, and a button switch.

A plurality of the position sensors 700 are installed at predetermined intervals in the window frame 1 to detect the position information of the window 100 and output the detected position information to the control unit 500. The position sensors 700 include optical detection means such as CDS.

The operation of the window opening / closing apparatus according to the present invention will now be described.

The control unit 500 calculates the indoor air pollution degree information and the outdoor air pollution degree information using the information detected from the indoor sensor 410 and the outdoor sensor 420. [

The control unit 500 compares the calculated indoor air pollution degree information and the outdoor air pollution degree information with a reference value for determining whether the windows 100 and the filter unit 200 are opened or closed.

As a result of the comparison, if the detected degree of contamination of the indoor air is greater than or equal to the reference value for determining the opening / closing of the window, the control unit 500 outputs an operation signal to the window driving unit 300 so as to open the window 100 for ventilation of the indoor air.

At this time, the window 100 is controlled to be opened to any one of 100%, 50%, and 30% according to the measured degree of contamination, and the window 100 is positioned at an accurate position using the position information input through the position sensor 700 So that it can be moved.

If the detected degree of pollution of the outdoor air is equal to or greater than the reference value for judging opening / closing of the filter unit, the control unit 500 outputs an ON signal to the actuator 130 so that the window 100 and the filter unit 200 So that the filter unit 200 blocks the opening of the window 100 due to the movement of the window 100 to prevent foreign substances from entering the room and the air in the room is discharged to the outside Allow ventilation to occur.

If the concentration of the detected dust is lower than the reference value for judging opening / closing of the filter unit, the control unit 500 outputs an off signal of the actuator 130 to the window unit 100 and the filter unit 200 So that the window 100 and the filter unit 200 can be kept separated so that only the window 100 can be opened.

Therefore, by selectively installing the filter unit according to the pollution degree of the outdoor air, ventilation can be performed irrespective of the external environment.
