[0037] The monitoring unit is used to monitor the opening and closing state of the window at the set time interval, and the closing time when the opening and closing state of the window is the closed window state.

[0038] The processing unit 2 is connected with the indoor and outdoor data acquisition unit 3 and the monitoring unit. The processing unit 2 is used to:

[0039] When the opening and closing state of the window is the open window state, and when the open window maintaining condition is met, the processing is ended; the open window maintaining condition includes that the outdoor temperature is in the outdoor temperature threshold range, and the outdoor air pollutant index is less than or equal to the outdoor air pollutant index calibration value; when any of the open window maintaining condition is not met, a closed window signal is generated;

[0040] When the opening and closing state of the window is the closed window state, it is determined whether the closed window time is less than or equal to the closed window duration set value; when the closed window time is less than or equal to the closed window duration set value, and the automatic open window condition is met, an automatic open window signal is generated; the automatic open window condition includes that the absolute value of the temperature difference between the outdoor temperature and the indoor temperature is less than or equal to the temperature difference reference value, the indoor oxygen concentration is less than or equal to the indoor oxygen concentration reference value, and the outdoor air pollutant index is less than or equal to the outdoor air pollutant index set value; when any of the automatic open window condition is not met, the processing is ended;

[0041] When the closed window time is greater than the closed window duration set value, and the display condition is met, a display signal is generated; the display condition includes that the absolute value of the temperature difference between the outdoor temperature and the indoor temperature is less than or equal to the temperature difference calibration value, the indoor oxygen concentration is less than or equal to the indoor oxygen concentration calibration value, and the outdoor air pollutant index is less than or equal to the outdoor air pollutant index calibration value; when any of the display signal is not met, the processing is ended.

[0042] The display unit 1 is connected to the processing unit 2. The display unit 1 is used to display prompt information according to the display signal.

[0043] The control unit 4 is connected to the processing unit 2. The control unit 4 is used to control the window to close when the window is open, and to control the window to open when the window is closed when the window is automatically opened.

[0044] The conditions for maintaining an open window, automatically opening a window, or displaying a window can be determined in any order. When the processing unit finishes processing, the window's open / closed state remains unchanged.

[0045] Furthermore, such as Figure 2 As shown, the control unit 4 includes a control module 41 and a sliding module 42.

[0046] The control module 41 is connected to the processing unit 2. The control module 41 is used to generate a first control signal based on a window closing signal and a second control signal based on an automatic window opening signal.

[0047] The sliding module 42 is connected to the control module 41. The sliding module 42 is used to control the window to close according to a first control signal and to control the window to open according to a second control signal.

[0048] The temperature difference correction value is calculated using the following formula:

[0049] t0 = KT + t.

[0050] In the formula, t0 is the temperature difference calibration value; K is the constant setting value; T is the window closing time; and t is the temperature difference reference value.

[0051] Optionally, the outdoor temperature threshold range can be adjusted based on geographical location using a database. Additionally, the outdoor temperature threshold range can also be adjusted based on season using a database.

[0052] Preferably, the display unit is a display screen.

[0053] Example

[0054] like Figure 3 As shown, the process is as follows: First, initialize by setting the window closing time setting value T0, the temperature difference baseline value t, the temperature difference correction value t0, and the minimum outdoor temperature t that allows the window to be opened. min The maximum outdoor temperature t that allows windows to be opened max, a constant setting value k, an indoor oxygen concentration reference value A, an indoor oxygen concentration revised value A0, an outdoor air pollutant index revised value P0, and an outdoor air pollutant index setting value is 100. Wherein, the outdoor temperature threshold range is greater than or equal to the minimum value of the outdoor temperature allowing window opening, and less than or equal to the maximum value of the outdoor temperature allowing window opening. The air pollutant index applies PSI (Pollutants Standard Index) index.

[0055] Based on the indoor data acquisition module 31, the indoor temperature t1 and the indoor oxygen concentration A1 are acquired according to the setting time interval; based on the outdoor data acquisition module 32, the outdoor temperature t2 and the outdoor air pollutant index P1 are acquired.

[0056] Based on the monitoring unit, the opening and closing state of the window is monitored according to the setting time interval, and the closed window time when the opening and closing state of the window is the closed window state.

[0057] Firstly, the opening and closing state of the window is judged.

[0058] When the opening and closing state of the window is the closed window state, it is judged whether the closed window time is less than or equal to the closed window duration setting value. If the closed window time is less than or equal to the closed window duration setting value, it is judged whether the absolute value of the temperature difference between the outdoor temperature and the indoor temperature is less than or equal to the temperature difference reference value; if yes, it is judged whether the indoor oxygen concentration is less than or equal to the indoor oxygen concentration reference value; if no, the processing unit ends the processing, and the opening and closing state of the window maintains the original state. It is judged whether the indoor oxygen concentration is less than or equal to the indoor oxygen concentration reference value; if yes, it is judged whether the outdoor air pollutant index is less than or equal to the outdoor air pollutant index setting value; if no, the processing unit ends the processing, and the opening and closing state of the window maintains the original state. It is judged whether the outdoor air pollutant index is less than or equal to the outdoor air pollutant index setting value; if yes, the processing unit generates an automatic window opening signal. The control unit 4 ends the closed window state according to the automatic window opening signal, and controls the window to open.

[0059] When the switch state of the window is the closed window state, it is determined whether the closed window time is less than or equal to the closed window duration setting value. If the closed window time is greater than the closed window duration setting value, a temperature difference correction value is generated according to the formula t0=KT+t. It is determined whether the absolute value of the temperature difference between the outdoor temperature and the indoor temperature is less than or equal to the temperature difference correction value. If yes, it is determined whether the indoor oxygen concentration is less than or equal to the indoor oxygen concentration correction value. If no, the processing unit ends the processing, and the switch state of the window is maintained. It is determined whether the indoor oxygen concentration is less than or equal to the indoor oxygen concentration correction value. If yes, it is determined whether the outdoor air pollutant index is less than or equal to the outdoor air pollutant index correction value. If no, the processing unit ends the processing, and the switch state of the window is maintained. It is determined whether the outdoor air pollutant index is less than or equal to the outdoor air pollutant index correction value. If yes, a display signal is generated. If no, the processing unit ends the processing, and the switch state of the window is maintained. The display unit 1 displays prompt information according to the display signal. The prompt information is 'the closed window time is long, and it is appropriate to open the window'.

[0060] When the switch state of the window is the open window state, it is determined whether the outdoor temperature is in the outdoor temperature threshold range. If yes, it is determined whether the outdoor air pollutant index is less than or equal to the outdoor air pollutant index correction value. If no, a closed window signal is generated. It is determined whether the outdoor air pollutant index is less than or equal to the outdoor air pollutant index correction value. If yes, the processing unit ends the processing, and the switch state of the window is maintained. If no, a closed window signal is generated. The control unit 4 ends the open window state according to the closed window signal and controls the closed window.

[0061] The present application is suitable for general residential buildings. People stay indoors for a long time and do not know when to open and close the window. Sometimes the window is always open, and sometimes the window is always closed, which is not conducive to the physical and mental health of people and is not conducive to energy saving and consumption reduction. The present application can open the window for natural ventilation when the outdoor conditions are good and close the window when the outdoor conditions are bad. At the same time, considering the inner heart of people, the present application provides the option of opening the window autonomously when the closed window time is too long.

[0062] The present application is also suitable for office buildings. Few people actively open and close the window in a closed office environment. The present application can automatically open and close the window according to environmental conditions.

[0063] Among them, the environmental conditions include automatic window opening conditions and display conditions.
