Abstract

The embodiment of the invention provides a human body detection method, a background temperature determining method, a device, and air conditioning equipment. The background temperature determining method comprises the following steps of for each channel, determining background temperature difference between the average detection temperature of the channel and the total average detection temperature; when the background temperature difference is greater than a background temperature different threshold value, determining the total average detection temperature as the current background temperature of the channel; when the background temperature difference is not greater than the background temperature different threshold value, determining the average detection temperature of the channel as the current background temperature of the channel. When human body detection is carried out based on the background temperature, the accuracy is higher.

Description

technical field [0001] The invention relates to the technical field of multi-channel infrared sensors, in particular to a human body detection method, a background temperature determination method, a device and an air conditioner. Background technique [0002] In the prior art, an infrared sensor is usually used to detect whether there is a human body in the detection space of the infrared sensor. Since the detection space of an infrared sensor is limited, multiple infrared sensors are usually used to detect at the same time in the prior art, and the multiple infrared sensors can be arranged in a specified manner according to actual needs, and the detection space of each infrared sensor can be As a channel, multiple infrared sensors are used to simultaneously detect the multi-channel area formed by the detection spaces of the multiple infrared sensors, which can cover a larger detection space. [0003] In the prior art, when multiple infrared sensors are used to detect whet...
