The invention discloses an intelligent family environment control method and
system. The method comprises the following steps that the
air pollution threshold value is preset; the user position is positioned in real time, the user speed is monitored, and the
user state and the leaving distance are judged; and the
indoor air quality is monitored in real time, purifier start control is conducted according to the
user state, when a user is at home and the air quality exceeds the
air pollution preset threshold value, a purifier is started, when the user leaves the home or the air quality does not reach the
air pollution preset threshold value, the purifier is stopped, and when the user returns home, the needed
air purification time is judged according to the current
indoor air quality, the needed home returning time is calculated in combination of the user leaving distance and speed, the purifier
start time is judged in combination of the needed
air purification time and the needed user home returning time, and air in a room is purified when the user returns home. Through
intelligent control, the user can enjoy the purified air all the time, and
power saving and energy saving can be achieved with the
maximum efficiency.
