If the person wants to control the window by himself, he only needs to press any function key on the remote control, and the window will first jump out of the automatic mode and enter the manual mode, and the system will execute the function corresponding to the function key of the remote control.

If people want the system to return to the automatic mode, they only need to press the corresponding button on the remote controller, and the system will enter the automatic mode.

The block diagram of the entire control system is shown in Figure 8.

The working of the invention:

1. Open and close the window

When the external weather is bad, the signals such as rainwater, temperature, light intensity and PM2.5 collected by various sensors in Fig. closure.

Equally, under the good situation of outside weather, be positioned at indoor sensor and detect CO Concentration is higher, and microprocessor judges to exceed limit value, sends the window opening and closing motor 11 in the window opening and closing module 1 of instruction to do reverse rotation, and the window opens and closes The closing module 1 controls each window unit to rotate a certain angle around the horizontal axis at the same time to perform ventilation. Both the CO2 concentration critical value and the window rotation angle can be manually set, and these adjustment functions are realized by the control system circuit.

2. Window lock

Before opening the window, the microprocessor first sends a signal to the steering gear 22 before realizing the window opening action, so that the steering gear 22 rotates at a certain angle, raises the locking claw 21, and the locking claw passes through the shaft from the hoop to lock the frame rod. 52A, so that the sash can be opened. After closing the window, the microprocessor can send a signal again to make the steering gear reversely rotate a certain angle, lower the locking pawl, and the locking pawl will lock the frame bar 52A through the shaft again, stop the window from opening, and lock the sash tight.

3. Curtain opening and closing

The curtains are slender blinds, and the curtain shutter opening and closing motor is connected with the rotation mechanism that controls the blinds. The opening and closing of the blinds can be controlled by controlling the rotation of the curtain shutter opening and closing motor in the curtain opening and closing module 3, so as to realize the adjustment of indoor light requirements .

4. Curtain lifting

The curtain lifting motor 41 links with the winding rope 44 that controls the blinds lifting, and controls the curtain lifting by controlling the curtain lifting motor 41 rotation. When the curtain needs to be lifted, the microprocessor will give the curtain lift motor 41 a signal to make the curtain lift motor 41 forward or reverse, so that the curtain can be lowered or raised.

The application functions of the present invention after integrating various sensors:

Auto mode features include:

1. When the indoor temperature is detected to be 5°C higher than the outdoor temperature, and both are above 20°C, open the window for ventilation.

2. When the indoor CO2 concentration is detected to be higher than the healthy value of 500ppm (micrograms per cubic meter), open the window for ventilation.

3. During the ventilation process, the window opening angle is automatically adjusted according to the outdoor wind direction, keeping it parallel to the wind direction.

4. Avoid frequent adjustment of windows due to changing outdoor wind directions, and avoid the phenomenon of "swinging with the wind".

5. Automatically close the window when it detects that it is raining outside.

6. When the outdoor PM2.5 value is detected to be high, the window will be closed automatically.

Manual mode features include:

1. The window can be opened manually, that is, the window locking mechanism automatically releases the window, and then the window is opened for ventilation.

2. The wind direction can be adjusted manually. When people don't want the ventilation rate to be high and the wind blows against people, they can manually adjust the window to any angle to change the wind direction.

3. The window can be closed manually, that is, the window is closed, and then the window locking mechanism locks the window.
