step S22: judging the possible direction of the wind source, and carrying out preparation monitoring in advance;
step S23: blades in the wind power monitoring module rotate under the action of wind power, an air inlet of the device at the moment is recorded, and the rotating speed Q is measured;
step S24: and transmitting the data to a smoke detection and calculation module in a data form to judge the source of the smoke.
6. The smart home central control system based on stable performance according to claim 5, characterized in that: the step S24 further includes the steps of:
step S241: the smoke detection module detects the source direction of smoke through a channel of the smoke detection module;
step S242: secondly, obtaining a drifting angle alpha of the smoke under the action of wind power through the rotating speed of the blades in the wind power monitoring module, wherein the alpha is Q and F;
step S253: acquiring the height H from the floor of the room to the smoke monitoring module, measuring and calculating the distance J from the smoke source,
step S254: when the estimated smoke source distance exceeds the range of the house, checking the opening and closing conditions of a house window;
step S255: if the window is opened in the smoke direction, the system judges that external smoke enters the room, and the sensitivity of the smoke alarm is reduced;
step S256: if the smoke alarm is in the low-sensitivity mode and still continuously receives smoke, the alarm prompt is still triggered, the corresponding window is closed, and the windows in other directions are opened for ventilation.
7. The smart home central control system based on stable performance according to claim 6, characterized in that: the step S3 further includes the steps of:
step S31: sending the indoor air condition to a cloud terminal through signal data;
step S32: the transmitted data comprises smoke conditions and air quality values, the data are respectively expressed by 8-bit integers and 8-bit decimal places, and in addition, 8-bit data are used for verification;
step S33: and accessing the data every R seconds through timed interruption, and returning to the indoor condition if the data is verified to be correct.
8. The smart home central control system based on stable performance according to claim 7, characterized in that: the step S5 further includes the steps of:
step S51: the system is connected with a user bracelet, when the user is detected to be in a deep sleep state, a night system is started, and time information is recorded when the ambient air quality is monitored;
step S52: establishing an indoor environment condition analysis model by taking the oxygen content in the air as a vertical axis and time as a horizontal axis, and predicting the indoor environment condition analysis model to a certain extent;
step S53: when the indoor air quality is lower than the threshold value U, the system judges that air replacement is needed;
step S54: reading historical data, acquiring the wind direction and the wind power, and opening a window capable of circulating air according to wind source information;
step S55: after air enters, the blades in the wind power monitoring module continuously blow fresh air to sink;
step S56: after P times, the ventilation window is closed.
9. The smart home central control system based on stable performance according to claim 8, characterized in that: the step S56 further includes the steps of:
step S561: acquiring a room space volume I and a ventilation window area A, wherein the rotating speed Q reflects the speed S of air circulation, and S is equal to D and Q;
step S562: the ventilation time P is measured and calculated,
