Abstract

The invention relates to an air conditioner human body induction method, device and system. The air conditioner human body induction method comprises the steps that whether human body movement exists in a room is detected through an infrared detection module, and an indoor environment temperature value T1 is detected in real time when human body movement exists; and an adjustment threshold value delta of the infrared detection module is calculated according to the indoor environment temperature value T1, and the detection distance and sensitivity of the infrared detection module are adjusted according to the adjustment threshold value delta. The adjustment threshold value of the infrared detection module is dynamically adjusted according the indoor environment temperature, and therefore when the environment temperature is close to the human body temperature, it is ensured that the infrared detection module has a long detection distance and proper sensibility.

Description

technical field [0001] The invention relates to the technical field of intelligent induction control of an air conditioner, in particular to a human body induction detection method, device and system for an air conditioner. Background technique [0002] One of the keys to the intelligentization of air conditioners is that the air conditioner must have an intelligent perception system. In order to enable the air conditioner to perceive the human body in the room, the air conditioner is usually equipped with an infrared sensor to realize the perception of the human body. Sensing the situation of the human body in the room. [0003] The digital pyroelectric infrared sensor integrates the digital intelligent control circuit and the human body detection sensitive source in the electromagnetic shielding cover, and the human body detection sensitive source couples the sensed human body movement signal to the digital intelligent integrated circuit chip through a very high impedance ...
