[0028] Please refer to Figure 1 , which is a flow chart of the radar-based air conditioning control method provided by the first embodiment of the present invention. The radar-based air conditioning control method provided by the first embodiment specifically includes the following steps.

[0029] Step S101, transmitting a radar signal.

[0030] Step S102, obtaining the echo signal reflected by the radar. If the target point cloud data sensed by the radar is obtained, the indoor target category, the target number, and whether the target is performing a preset adjustment gesture are determined according to the target point cloud data. Specifically, a radar sensing module is set in the air conditioner. The radar module includes a transmitter and a receiver and a signal processor. The transmitter and the receiver are used to transmit and receive radar signals. The signal processor processes the received radar signal to form target point cloud data, and determines the indoor target category, calculates the target number, and determines whether the target is performing a preset adjustment gesture according to the target point cloud data. Further, the signal processor first identifies the radar signal reflected by the target according to the point radar signal, analyzes the radar signal of the target for processing to obtain the target point cloud data, and then analyzes the target point cloud data to determine whether the target is performing a preset adjustment gesture. In some feasible embodiments, the signal processor can identify the radar signal reflected by the target according to the frequency of the reflected radar signal. It can be understood that the frequency of the radar signal emitted by different objects will be different due to their own composition. Please refer to steps S201-step S204 for details.

[0031] Step S103: forming target point cloud data according to the echo signal.

[0032] Step S104, according to the target point cloud data, identify the indoor target category, calculate the target number, and the preset adjustment gesture of the target to obtain a corresponding detection signal, the detection signal includes the target category, the target number, and the preset adjustment gesture. Please refer to the adjustment gesture Figure 6 , Figure 6 The gestures shown are for illustrative purposes only and are not limiting. Specifically, the radar transmits a continuous wave with changing frequency during the sweep period. The echo reflected by the object has a certain frequency difference from the transmitted signal. By measuring the frequency difference, the distance information between the target and the radar can be obtained. In some feasible embodiments, the preset adjustment gesture is obtained by counting the target point cloud data of all hands and calculating the average value. In other feasible embodiments, several feature points are selected to represent all the hand feature points for calculation. For example, the target point cloud data of the five fingertips of the hand are used to replace the target point cloud data of all the hands, thereby obtaining a preset adjustment gesture.

[0033] Step S105, sending the detection signal to the main control chip, for the main control chip to make a control strategy according to the detection signal, and the control strategy is used to control the air conditioner. In some feasible embodiments, when the air conditioner is in the on state, the air conditioner can be controlled to adjust the temperature. Specifically, when the air conditioner is in the cooling state, the preset temperature of the air conditioner is lowered in sequence according to the preset mode setting. For example, the air conditioner turn-on temperature is set to 26°C in summer. The unit for lowering the temperature is 1°C, and the temperature decreases sequentially. The lowest temperature is 18°C. When the radar senses the preset adjustment gesture for the first time, the air conditioner is turned on and cooled at 26°C. When the radar senses the preset adjustment gesture for the second time, the air conditioner will reduce the cooling temperature by one degree to 25°C.

[0034] In some feasible embodiments, when the air conditioner is in the on state, the air conditioner adjustment mode is controlled. Specifically, when the air conditioner is in the cooling state, the corresponding modes are started in sequence according to the preset mode settings. When the radar senses an adjustment gesture that meets the preset conditions, it enters the next mode, for example, from the cooling mode to the air supply mode. The user can preset the mode sequence of the air conditioner through the control panel. In this embodiment, the air conditioner replacement modes are cooling, air supply, and dehumidification. When the radar senses the user's first adjustment gesture that meets the preset conditions, the air conditioner turns on the cooling mode. When the radar detects the second adjustment gesture, the air conditioner turns on the air supply mode. When the radar detects the third adjustment gesture, the air conditioner turns on the dehumidification mode.

[0035] In some feasible embodiments, when the air conditioner is in the air supply mode, the radar detects a preset adjustment gesture, and the air conditioner changes the direction of the air supply. Specifically, the order of wind direction conversion is the order of wind direction of the air conditioner preset by the control panel. For example, left and right air supply, up and down air supply. When the air conditioner is in the air supply mode, the default wind direction is left and right air supply, and the radar detects the preset adjustment gesture and changes the wind direction to up and down air supply.

[0036] In some feasible embodiments, when the air conditioner is in the on state, the air conditioner is controlled to be turned off. Specifically, when the air conditioner is currently in the on state, when the radar senses the adjustment gesture, the air conditioner is controlled to be turned off.

[0037] In other feasible embodiments, when the radar does not sense the echo reflected by the target again after 10 minutes after the last time it sensed the target, the air conditioner enters the energy-saving state. When the radar does not sense the echo reflected by the target again after 30 minutes after the last time it sensed the target, the air conditioner is turned off.

[0038] In this embodiment, various set parameters are only used as examples and are not limited thereto. The corresponding various settings can be set through an external control panel of the air conditioner, or other feasible setting schemes.

[0039] Please refer to Figure 2, which is a sub-step flow chart of step S101 provided by an embodiment of the present invention. Step S104, each target is numbered, identifying the indoor target category, calculating the number of targets, and obtaining the corresponding detection signal by the preset adjustment gesture of the target, and step S104 specifically includes the following steps.

[0040] Step S201, identifying human targets and non-human targets based on the target point cloud data. Each target is labeled. In this embodiment, the non-human can be a pet dog or cat kept at home.

[0041] Step S202: When the target category is non-human, the target is ignored. When the target is a pet dog or a pet cat, the height option is recorded as 0, and the target is not counted.

[0042] Step S203: When the target category is human body, count the targets to obtain the number of targets. Fig.10 , which is a control interface. 101 is a maximum distance display box, 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 figure are only examples and are not limited.

[0043] Step S204, identifying whether the numbered target is performing a preset adjustment gesture. Fig.10 , the human targets in the target display area 102 are marked with a counting mark 1021, and the non-human targets are marked with an ignore mark 1022, and the targets with the counting mark 1021 are counted. Determine whether the numbered targets are performing a preset adjustment gesture. In this embodiment, the preset adjustment gestures include waving up, waving down, waving to the left, and waving to the right. Turn on the air conditioner according to the preset adjustment gesture and start the air supply mode related to the gesture. Specifically, when the gesture is waving up, the air conditioner turns on the upward air supply mode; when the gesture is waving down, the air conditioner turns on the downward air supply mode; when the gesture is waving to the left, the air conditioner turns on the left air supply mode; when the gesture is waving to the right, the air conditioner turns on the right air supply mode. In this embodiment, the preset gesture can also be used to turn off the air conditioner.

[0044] In the above embodiment, the air conditioner is controlled to turn on the wind direction, temperature, and humidity mode of the specified wind direction through the preset adjustment gesture, thereby improving the user's experience of using the smart air conditioner.

[0045] Please refer to Figure 3, which is a sub-flow chart of the air conditioning control method based on radar sensing provided by the first embodiment of the present invention. The difference between the air conditioning control method based on radar sensing provided by the second embodiment and the air conditioning control method based on radar sensing provided by the first embodiment is that before determining whether the adjustment gesture is a preset adjustment gesture, the air conditioning control method based on radar sensing provided by the second embodiment further includes the following steps.

[0046] Step S301, obtaining the distance between the target and the air conditioner according to the target point cloud data of the numbered target.

[0047] Step S302, determine whether the distance is less than the preset effective perception distance. In this embodiment, the preset effective perception distance is divided according to the size of the indoor area. For example, the area is 5*5m 2 In the room, the preset effective sensing distance is 3m, that is, the area 3 meters away from the air conditioner in the room is the effective area, and the air conditioner can be controlled quickly with the preset gestures and the preset adjustment gestures in this area.

[0048] Step S303: when the distance is less than the preset effective perception distance, determine whether the adjustment gesture is a preset adjustment gesture.

[0049] The above embodiment divides the preset perception distance according to the actual application scenario, combines it with the actual living habits, reduces misjudgment and improves the accuracy of air conditioning perception.

[0050] In some feasible embodiments, the wind direction adjustment operation, temperature adjustment operation and humidity adjustment operation that the air conditioner needs to perform are obtained according to the preset adjustment gesture, target category and target number. Step S102 specifically includes the following steps. Determine whether it is necessary to increase the temperature, adjust the wind direction or reduce the humidity according to the preset adjustment gesture. Obtain the movement trajectory of the person in the target. When the temperature needs to be increased, the specific temperature to be increased, the direction of the wind direction and the specific humidity to be reduced are determined according to the target number and the movement trajectory of the person in the target. Specifically, in some feasible implementations, the preset position relationship is that the height of the hand is higher than the height of the elbow, that is, the state of the hand being raised. In other feasible embodiments, the preset position relationship is 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 alternately.

[0051] When the position relationship belongs to the preset position relationship, it is determined whether the hand and the elbow are performing a preset adjustment gesture. Specifically, the preset adjustment gesture is to keep the hand raised and swing back and forth within a certain range.

[0052] Please refer to Figure 4, which is a sub-step flow chart of step S103 provided by an embodiment of the present invention. Step S103, detecting whether the target is performing a preset adjustment gesture according to the target point cloud data, specifically includes the following steps.

[0053] Step S401, extracting hand feature points and elbow feature points according to the target point cloud data.

[0054] Step S402, calculating the positional relationship between the hand feature points and the elbow feature points.

[0055] Step S403, determining whether the position relationship belongs to a preset position relationship.

[0056] Step S404: When the position relationship belongs to the preset position relationship, it is determined whether the hand and the elbow are performing a preset adjustment gesture.

[0057] Please refer to Figure 5 , which is a radar working diagram of a radar used in an air conditioning control method according to a first embodiment of the present invention. The radar tool body of the radar used in an air conditioning control method according to the first embodiment includes the following steps.

[0058] Step S601, detect whether the reflected echo signal is obtained. If the target point cloud data sensed by the radar is obtained, the indoor target category, the target number, and whether the target is performing a preset adjustment gesture are determined according to the target point cloud data. Specifically, a radar sensing module is set in the air conditioner. The radar module includes a transmitter and a receiver and a signal processor. The transmitter and the receiver are used to transmit and receive radar signals. The signal processor processes the received radar signal to form target point cloud data, and determines the indoor target category, calculates the target number, and determines whether the target is performing a preset adjustment gesture according to the target point cloud data. Further, the signal processor first identifies the radar signal reflected from the target according to the point radar signal, analyzes the radar signal of the target for processing to obtain the target point cloud data, and then analyzes the target point cloud data to determine whether the target is performing a preset adjustment gesture. In some feasible embodiments, the signal processor can identify the radar signal reflected from the target according to the frequency of the reflected radar signal. It can be understood that the frequency of the radar signal emitted by different objects will be different due to their own composition.

[0059] Step S602: forming target point cloud data according to the echo signal.

[0060] Step S603: Identify the indoor target category, calculate the target quantity, and the preset adjustment gesture of the target according to the target point cloud data to obtain a corresponding detection signal, which includes the target category, the target quantity, and the preset adjustment gesture. Figure 6 , Figure 6The gestures shown are for illustrative purposes only and are not limiting. Specifically, the radar transmits a continuous wave with changing frequency during the sweep period. The echo reflected by the object has a certain frequency difference with the transmitted signal. By measuring the frequency difference, the distance information between the target and the radar can be obtained. In some feasible embodiments, the preset adjustment gesture is obtained by counting the target point cloud data of all hands and calculating the average value. In other feasible embodiments, several feature points are selected to represent all the hand feature points for calculation. For example, the target point cloud data of the five fingertips of the hand are used to replace the target point cloud data of all the hands, thereby obtaining a preset adjustment gesture.

[0061] Step S604, sending the detection signal to the main control chip, for the main control chip to make a control strategy according to the detection signal, and the control strategy is used to control the air conditioner. In some feasible embodiments, when the air conditioner is in the on state, the air conditioner can be controlled to adjust the temperature. Specifically, when the air conditioner is in the cooling state, the preset temperature of the air conditioner is lowered in sequence according to the preset mode setting. For example, the air conditioner is set to 26°C in summer. The unit for lowering the temperature is 1°C, and the temperature decreases sequentially. The lowest temperature is 18°C. When the radar senses the preset adjustment gesture for the first time, the air conditioner is turned on and cooled at 26°C. When the radar senses the preset adjustment gesture for the second time, the air conditioner will reduce the cooling temperature by one degree to 25°C.

[0062] The difference between the air conditioning control method based on radar sensing provided by the third embodiment and the air conditioning control method based on radar sensing provided by the first embodiment is that before the air conditioning control method based on radar sensing controls the air conditioning to be turned on, the air conditioning control method based on radar sensing provided by the third embodiment further includes the following steps: obtaining the temperature and humidity of the surrounding environment. Selecting the mode in which the air conditioning is to be turned on according to the temperature and humidity. Calculating the working time and sleep time of the air conditioning when it is turned on according to the mode.

[0063] In the above embodiment, the use of radar to determine the preset adjustment gesture speed takes advantage of the radar's advantage in measuring speed, and will not be affected by other environmental factors such as temperature and humidity. On the basis of identifying the preset adjustment gesture action, the user's command is confirmed according to the preset adjustment gesture speed, thereby improving the user's use experience of the smart air conditioner. Furthermore, using the user's preset adjustment gesture speed to confirm the air conditioner command will not infringe on the user's privacy like confirming the command with a camera, and accurate control of the air conditioner can be achieved without infringing on the user's privacy.

[0064] In some other feasible embodiments of the air conditioning control method based on radar sensing, when the air conditioning is in the on state, if the target point cloud data sensed by the radar is not obtained for a preset time, the air conditioning is controlled to be turned off. In the above embodiment, the radar monitors the user status indoors in real time, and when it is confirmed that there is no user indoors, the air conditioning is turned off to save energy.

[0065] Further, in the embodiments of the present invention, please refer to Figure 7 The radar is a 79HZ millimeter-wave radar module.

[0066] In the above embodiment, the radar-based air conditioning control method recognizes the user's speed adjustment gesture to control the air conditioning to turn on the wind direction mode of the specified wind direction or turn off the air conditioning according to the target point cloud data. This makes it more convenient for users to operate the air conditioning and improves the convenience of life. The radar-based air conditioning control method realizes accurate control of the air conditioning to achieve energy-saving effect by accurately identifying the preset adjustment gesture speed.
