Position detection method, air conditioner and control method of air conditioner

Abstract

The invention relates to a position detection method, an air conditioner and a control method of the air conditioner. The position detection method comprises the steps of acquiring position information which is fed back by a microwave sensor most recently and used for representing the position of a detection target; judging whether the position of the detection target is in a preset detection areaor not according to the position information; and if yes, determining that the detection target is always in the preset detection area. Therefore, even if the microwave sensor always does not acquirethe position information of the detection target in the later time, the detection target can still be considered to be continuously located in the preset detection area; and under the condition, thedetection target is in a static state in the preset detection area or the activity amount of the detection target does not reach a detection threshold of the microwave sensor. Therefore, the purposesof static detection and low-activity target detection are achieved by using the microwave sensor. According to the air conditioner control method, a target human body is detected through the positiondetection method, and the situation that user experience is affected by misjudgment can be avoided.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a microwave sensor-based position detection method, an air conditioner and its control method, and a computer-readable storage medium. Background technique [0002] At present, indoor non-contact position sensors mainly include infrared and microwave. Thermal release point sensors have low detection accuracy and a small detection range; thermopile sensors have a high cost and a relatively small detection range, and basically require an electric mechanism to achieve effective detection of the area. Microwave sensor is a device that uses microwave characteristics to detect some physical quantities. It has high detection sensitivity, large detection range, and lower cost than thermopile sensors. It is gradually being used in the field of home appliance position detection. Due to cost constraints, microwave sensors, especially 24G sensors, cannot detect static targets. Co...
