Human body detection method, human body detection equipment and air conditioner

Abstract

The invention provides a human body detection method, human body detection equipment and an air conditioner. The human body detection method comprises the following steps that when a detection area ofa first human body sensor is adjusted to be a first detection area by rotating the first human body sensor and a detection area of a second human body sensor is adjusted to be a second detection areaby rotating the second human body sensor, first detection signals detected by the first human body sensor and the second human body sensor are acquired; when the detection area of the first human body sensor is adjusted to be a third detection area by rotating the first human body sensor and the detection area of the second human body sensor is adjusted to be a fourth detection area by rotating the second human body sensor, detected second detection signals are acquired; and whether a person exists in the overlapping area or not is determined through the first detection signals and the seconddetection signals. According to the method and the equipment, whether the person exists in the overlapping area of the detection areas of the two human body sensors or not can be accurately judged, so that the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of household appliances, in particular to a human body detection method, human body detection equipment and an air conditioner. Background technique [0002] In the existing related technology, the function of partition detection is realized by dual pyroelectric sensors, and the detection areas of the two pyroelectric sensors can be roughly divided into three detection areas: left, middle and right, and the middle area is the detection area of ​​the two pyroelectric sensors. In the overlapping area of ​​the detection area, the air guide strip of the air conditioner is controlled according to the signals detected by the three detection areas, so that the wind blows people or the wind avoids people. Since the pyroelectric sensor is a kind of infrared sensor, the detection principle of the pyroelectric sensor is to cooperate with the lens to detect the moving heat source within the detection angle and...

AI Technical Summary

Problems solved by technology

Since the pyroelectric sensor is a kind of infrared sensor, the detection principle of the pyroelectric sensor is to cooperate with the lens to detect the moving heat source within the detection angle and detection distance. As long as there is a moving heat source, the pyroelectric sensor will detect the signal. Therefore, the pyroelectric sensor cannot determine the number of people and the temperature of the heat source, so the pyroelectric sensor cannot determine the area

[0003] For example, assume that there are two situations as follows: Situation 1: There are two people, one is in the left area and the other is in the right area; Situation 2: There is only one person, and this person is in the middle area. Electric sensors will detect people at the same time, but cannot accurately determine which of the above situations

The existing solution is to judge the above two situations as people in the middle area, but this method is only applicable to the single-player mode. In the double-player mode, if one person is in the left area and the other is in the right area, the wind will not blow. to the human situation, which greatly affects the user experience
