Please refer to fig. 1, which is a flowchart illustrating a radar-based air conditioning control method according to a first embodiment of the present invention. The radar-based air conditioner control method provided by the first embodiment specifically comprises the following steps.
Step S101, transmitting radar signals.
And step S102, acquiring an echo signal reflected by the radar. And if the target point cloud data sensed by the radar is acquired, judging the type of the indoor targets, calculating the number of the targets and judging whether the targets are carrying out preset adjusting gestures according to the target point cloud data. Specifically, a radar sensing module is arranged in the air conditioner. The radar module comprises a transmitting receiver and a signal processor. The transmitting and receiving device is used for transmitting and receiving radar signals. The signal processor processes the received radar signals to form point cloud data, judges the type of the indoor targets according to the point cloud data, calculates the number of the targets and judges whether the targets are carrying out preset adjusting gestures. Furthermore, the signal processor firstly identifies radar signals which represent that the target reflects back according to the point radar signals, analyzes the radar signals of the target, processes the radar signals to obtain point cloud data, and then analyzes the point cloud data to obtain whether the target carries out a preset adjusting gesture. In some possible embodiments, the signal processor may identify the radar signal reflected by the target according to the frequency of the reflected radar signal. It will be appreciated that different objects will differ in their own frequency of the transmitted radar signal. Please refer to step S201-step S204.
And step S103, forming a target point cloud signal according to the echo signal.
And S104, identifying the indoor target type according to the target point cloud signals, calculating the target number, and obtaining corresponding detection signals according to preset adjusting gestures of the targets, wherein the detection signals comprise the target type, the target number and the preset adjusting gestures. Adjustment gesture referring to fig. 6, the gesture shown in fig. 6 is exemplary only and not limiting. Specifically, the radar transmits continuous waves with variable frequencies in a sweep frequency period, echoes reflected by an object have a certain frequency difference with a transmitted signal, and distance information between a target and the radar can be obtained by measuring the frequency difference. In some possible embodiments, the preset adjustment gesture is obtained by counting all the point cloud data of the hand and calculating the average value. In other possible embodiments, several feature points are selected to represent all the hand feature points for calculation, for example, the point cloud data of five finger tips of the hand is used to replace all the point cloud data of the hand, so as to obtain the preset adjustment gesture.
And step S105, sending the detection signal to a main control chip for the main control chip to make a control strategy according to the detection signal, wherein the control strategy is used for controlling the air conditioner. In some possible embodiments, the air conditioner may be controlled to adjust the temperature when the air conditioner is in an on state. Specifically, when the air conditioner is in a cooling state, the preset temperature of the air conditioner is turned down in sequence according to the preset mode setting, for example, the air conditioner turn-on temperature is set at 26 ℃ in summer. The unit of lowering the temperature is 1 ℃, the temperature is lowered in sequence, the lowest temperature is 18 ℃, when the radar senses that the preset adjusting gesture is met for the first time, the air conditioner is started and is cooled according to 26 ℃, and when the radar senses that the preset adjusting gesture is met for the second time, the air conditioner lowers the cooling temperature by one degree and is lowered to 25 ℃.
In some possible embodiments, the air conditioner adjustment mode is controlled when the air conditioner is in an on state. Specifically, when the air conditioner is in a refrigerating state, corresponding modes are sequentially started according to preset mode setting, when the radar senses that a preset adjusting gesture is met, the next mode is entered, for example, the air supply mode is entered from the refrigerating mode, and a user can preset the mode sequence of the air conditioner through the control panel. In this embodiment, the replacement mode of the air conditioner is refrigeration, air supply, and dehumidification in this order. When the radar senses that the user accords with the adjusting gesture of the preset condition for the first time, the air conditioner starts the refrigeration mode, when the radar monitors the adjusting gesture for the second time, the air conditioner starts the air supply mode, and when the radar monitors the adjusting gesture for the third time, the air conditioner starts the dehumidification mode.
In some possible embodiments, when the air conditioner is in the air supply mode, the radar detects a preset adjusting gesture, and the air conditioner converts the wind direction of the supplied air. Specifically, the wind direction conversion sequence is the wind direction sequence of the air conditioner preset through the control panel. For example, the air is blown to the left and right, and blown to the top and bottom. When the air conditioner is in an air supply mode, the default wind direction is left-right air supply, and the radar converts the wind direction into up-down air supply after monitoring a preset adjusting gesture.
In some possible embodiments, the air conditioner is controlled to be turned off when the air conditioner is in an on state. Specifically, when the air conditioner is in an on state at present, when the radar senses an adjusting gesture, the air conditioner is controlled to be turned off.
In other possible embodiments, the air conditioner enters the energy saving state when the radar does not sense the echo reflected by the target again after the target is sensed for the last time for 10 minutes. When the radar does not sense the echo reflected by the target again after the target is sensed for the last time and 30 minutes later, the air conditioner is turned off.
In this embodiment, the parameters of various settings are only exemplary and not limited, and the corresponding various settings may be set through an external control panel of the air conditioner, or other feasible setting schemes.

And S202, when the object type is a non-human body, ignoring the object. When the target is a pet dog or cat, the height option is marked as 0 and the target is not counted.
And step S203, counting the targets to obtain the target number when the target category is a human body. Please refer to fig. 10, which is a control interface. 101 is a maximum distance display frame, 102 is a target display area, 103 is a radar-related parameter display area, and 104 is a target-related parameter display area. The parameters shown in the figures are exemplary only and not limiting.
And step S204, identifying whether the numbered target is performing a preset adjusting gesture. Referring again to fig. 10, the objects with the count mark 1021 are counted by the human object in the object display area 102, and the objects other than the human object with the ignore mark 1022.

In this embodiment, the preset adjustment gestures include an upward swipe, a downward swipe, a leftward swipe, and a rightward swipe. And starting the air conditioner according to a preset adjusting gesture and starting an air supply mode related to the gesture. Specifically, when the gesture is swinging upwards, the air conditioner starts an upward air supply mode; when the gesture is waving to the next shift, the air conditioner starts a downward air supply mode; when the gesture is swinging leftwards, the air conditioner starts a left air supply mode; and when the gesture is to wave to the right, the air conditioner starts a right air supply mode. In this embodiment, the preset gesture may also be used to turn off the air conditioner.

For example, an area of 5 x 5m2In the room, the preset effective sensing distance is 3m, namely, the areas of the room, which are 3 meters away from the air conditioner, are effective areas, and the air conditioner can be controlled by preset adjusting gestures in the areas, wherein the preset adjusting gestures can be quickly preset by preset gestures.
Step S303, when the distance is smaller than the preset effective sensing distance, judging whether the adjusting gesture is a preset adjusting gesture.
According to the embodiment, the preset sensing distance is divided according to the actual application scene, and the accuracy of air conditioner sensing is improved by reducing misjudgment in combination with the actual living habits.
In some possible embodiments, the wind direction adjusting operation, the temperature adjusting operation and the humidity adjusting operation that the air conditioner needs to perform are obtained according to the preset adjusting gesture, the target category and the target number. Step S102 specifically includes the following steps. And judging whether the temperature needs to be increased, the wind direction needs to be adjusted or the humidity needs to be reduced according to a preset adjusting gesture. And acquiring the motion trail of the person in the target. When temperature rise is needed, the specific temperature needing to be raised, the direction of the wind direction and the specific humidity needing to be lowered are judged according to the target number and the motion trail of the personnel in the target. Specifically, in some possible implementations, the predetermined positional relationship is a height of the hand being higher than a height of the elbow, i.e., a state in which the hand is lifted. In other possible embodiments, the predetermined positional relationship is such that the height of the hand is higher than the height of the elbow and the height of the hand is lower than the height of the elbow alternate.
