Description

How to open and close windows automatically

The present invention relates to a method for automatically opening and closing a window, and more particularly, to an automatic window opening and closing method for automatically opening and closing a window for injecting fresh air into an interior.

In general, the window is a device for injecting fresh air into the interior of a building, such as a private house or apartment, and is not a device for cooling the air, such as air conditioning.

In addition, windows have an advantage over air cleaners in that they provide fresh air to humans with faster air circulation than electric air cleaners. In other words, the air purifier removes particles from indoor air such as cigarette smoke, and it takes a long time to clean the room filled with cigarette smoke because the indoor air circulation is slow due to the air cleaner.

However, due to the rapid flow of bad indoor air and fresh air outside, the room filled with tobacco smoke is ventilated within a relatively short time.

On the other hand, such a conventional window is opened and closed manually after the user recognizes the environmental conditions of the external or internal that is not always constant. For example, after rain or snow, the room temperature rises and the indoor air pollution is recognized by the user, the window is operated manually. Moreover, the inconvenience of having to manually operate the windows often occurs during the daytime when the temperature rises the most during the day and the dawn when the temperature is lowest.

The present invention is to solve the above problems, an object of the present invention is to provide a window automatic opening and closing method that can improve the operability of the window by automatically opening and closing the window according to the external environment.

In order to achieve the above object, the present invention provides an automatic mode determination step of determining whether the automatic mode is selected by the user after the initial step of closing the window is completed, and it is determined that the automatic mode is selected in the automatic mode determination step. Calculating a difference between a first input step of inputting a first detection signal of an internal sensor installed in the room, a magnitude of the first detection signal inputted from the first input step, and a pre-stored set value in order to detect an indoor temperature; A drive signal generation step of generating a drive signal from the calculated difference signal magnitude and positive and negative components, a window control step of controlling a window to a window opening and / or closing degree determined according to the drive signal of the drive signal generation step; Second detection input from outdoor second detection sensor to detect external weather condition during window control step A second input step of inputting a call, a second judging step of judging whether it is currently raining from the second detection signal of the second input step, and a control for closing the window when it is determined that it is currently raining in the second judging step A control signal generating step of generating a signal, a window closing step of closing a window according to the control signal of the control signal generating step, and determining whether it is currently snowing when it is determined that it is not currently raining in the second judging step, If it is determined that the control signal generation step proceeds to the third determination step characterized in that it comprises.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing the configuration of a window to which the present invention is applied. Here, the internal sensor 10, the external sensor 20, the microcomputer 30, the motor drive unit 40 and the window is provided.

Here, the internal sensor 10 is installed in the room to detect the temperature and pollution degree of the room and output the first detection signal. Then, the external sensor 10 is installed outdoors to detect the outdoor environment, for example rain or snow, and outputs a second detection signal.

The microcomputer 30 receives the first detection signal of the internal sensor 10 and calculates a difference between the magnitude of the first detection signal and a preset stored value, and opens the window according to the magnitude and the positive and negative components of the calculated difference signal. A driving signal for controlling the opening and / or closing degree is generated, and a control signal for controlling the opening and / or closing of the window is generated according to the second detection signal.

The motor driver 40 is configured of a motor, and opens and closes the window 50 by operating the motor according to the driving signal of the microcomputer 30. That is, when the difference between the magnitude of the first detection signal and the preset value is a positive component and the magnitude is large, the opening degree of the window 50 is increased, and the difference between the magnitude of the first detection signal and the preset value is the positive component. And when the size is small the opening degree of the window 50 is small. When the difference between the magnitude of the first detection signal and the pre-stored set value is a negative component and the magnitude is large, the closing degree of the window is increased, and the difference between the magnitude of the first detection signal and the pre-stored set value is a negative component and the magnitude is large. When it is small, the window is closed.

When the control signal supplied according to the difference between the first detection signal and the set value is input, the opening and / or closing of the window 50 is controlled.

Figure 2 is a detailed flowchart showing the automatic window opening and closing process according to the present invention, a process of automatically opening and closing the window will be described in more detail with reference to FIG.

First, when the initial step S1 of closing the window is completed, the process proceeds to the automatic mode determination step S2 of determining whether the automatic mode is selected by the user.

In addition, the automatic mode determination step S2 determines whether the automatic mode is selected by the user, and when the automatic mode is determined in the automatic mode determination step S2, an internal sensor installed in the room to detect the indoor temperature. A first input step S3 of inputting a first detection signal of is performed.

The first input step S3 inputs the first detection signal of the internal sensor, compares the first detection signal of the first input step S3 with a preset setting value, wherein the magnitude and setting value of the first detection signal The difference is calculated, and the process proceeds to the driving signal generation step S5 of generating the driving signal according to the magnitude and the positive and negative components of the calculated difference signal.

In addition, the driving signal generating step (S5) outputs the driving signal generated according to the magnitude of the difference signal and the positive and negative components, and when the output of the driving signal is completed, proceeds to the window control step (S6), the window control step ( S6) varies the opening and / or closing of the window depending on the magnitude of the drive signal and the positive and negative components. Then, the process proceeds to the second input step S7 of inputting the second detection signal during the execution of the window control step S6.

In the second input step S7, a second detection signal is input from a second detection sensor that senses an outdoor environment, and the second input signal S7 determines whether it is currently raining outside from the second detection signal of the second input step S7. Proceed to step 2 (S8).

In addition, the second determination step S8 determines whether it is currently raining outside from the second detection signal, and when the second determination step S8 determines that it is currently raining, a control signal for generating a control signal for closing the window. Proceeding to the generation step (S9), the control signal generation step (S9) generates a control signal for closing the window when it is determined that the current rain.

When the control signal generation step (S9) is completed, proceeds to the window closing step (S10) for closing the window according to the control signal of the control signal generation step, the window closing step (S10) is controlled in the control signal generation step (S8) At the signal, close the window to prevent rain from entering the room.

In addition, when it is determined that there is no current rain in the second determination step (S8), the process proceeds to the third determination step (S11) of determining whether the current snow comes, and when it is determined that the current snow comes in the third determination step (S11), Proceeds to the control signal generation step (S9).

On the other hand, if it is determined that there is no snow currently in the third determination step (S11), proceeds to the comparison step (S4), and if it is determined in the automatic mode determination step (S2) that the automatic mode of the current window is not set, the loop Quit.

As described above, the automatic window opening and closing method according to the present invention has an effect of improving the operability of the window by controlling the opening degree and the opening and / or closing of the window according to the indoor and outdoor environmental conditions.
