Air-conditioning system with human body induction control function

The utility model discloses an air-conditioning system with a human body induction control function, wherein a pyroelectric infrared probe arranged on a human body induction module circuit converts moving signals of objects to be detected to electrical signals, after being processed, the electrical signals are transmitted to a central controller, and the central controller controls the air-conditioning system to operate through a loading control circuit combining the current operation state of the air-conditioning system. A stepping motor in loading obtains required rotating angle, rotating speed and rotating direction instructions so as to finish air blowing state control. A program guidance (PG) motor obtains relay conduction time instruction of a zero passage sampling point and finishes indoor fan air speed control. A compressor, an outer fan and a change valve receive instructions sent by the central controller to finish switching on/off control of an air-conditioner. A buzzer can give prompt when people comes. A household appliance automatically stops operation in an energy-saving mode. According to requirements of the human body, the air-conditioning system with the human body induction control function achieves intellectualization of air-conditioning control of being automatic, energy-saving and capable of giving safety prompt.
