It is to be understood that the first location information and the second location information are both determined using the location information of the fan as a coordinate origin, and the location coordinates of the air conditioner and the location coordinates of the user both belong to the same coordinate system, so that the orientation information of the user with respect to the air conditioner can be determined based on the first location information and the second location information.
Wherein the orientation information comprises an orientation angle.
In some embodiments, according to the position coordinates of the user and the position coordinates of the air conditioner, the position coordinates of the air conditioner are used as a coordinate origin, and the azimuth angle of the user relative to the air conditioner can be determined. It should be noted that, in the rectangular coordinate system, the azimuth angle is an included angle between the position coordinate of the user and the coordinate main axis. For example, the coordinate main axis may be an X axis or a Y axis.
For example, as shown in fig. 7, fig. 7 is a schematic diagram for determining an orientation angle of the user with respect to the air conditioner according to the position coordinates of the user. In the rectangular coordinate system in fig. 7, the origin of coordinates represents the position coordinates of the air conditioner; point F represents the user's position coordinates (X8-X6, y8-y6), and the orientation angle a is the angle between the user's position coordinates and the coordinate X axis.

Figure BDA0002305039070000101
further azimuth angles can be found:
Figure BDA0002305039070000102
wherein Δ x represents an abscissa of the position coordinate of the user, and Δ y represents an ordinate of the position coordinate of the user; for example, Δ x is x8-x6, and Δ y is y8-y 6.
For example, if the position coordinate of the user relative to the fan is (350, 300), the coordinate azimuth angle a of the user is 50 ° calculated according to the tangent formula of the triangle.
Specifically, after the azimuth angle of the user is calculated, the blowing direction of the air conditioner is determined according to the azimuth angle.
As can be understood, the azimuth angle corresponds to the blowing direction of the air conditioner one by one; the user is located at the 50-degree azimuth angle of the air conditioner, and the blowing direction of the air conditioner is correspondingly adjusted to be 50 degrees during blowing so as to aim at the user to blow air.
Illustratively, the azimuth angle of 50 ° is sent to the air conditioner, so that the air conditioner adjusts the blowing direction to be 50 ° according to the azimuth angle.
Determining the direction information of the user relative to the air conditioner according to the first position information and the second position information, and further determining the blowing direction of the air conditioner; can blow to user's position, travelling comfort when improving the user and blowing.
Specifically, a first azimuth angle of the air conditioner relative to the fan is determined according to the first position information; determining a second azimuth angle of the user relative to the fan according to the second position information; and determining the air supply range corresponding to the fan according to the first azimuth angle and the second azimuth angle.
It can be understood that, in a rectangular coordinate system with the position coordinate of the fan as the origin, the first azimuth is an included angle between the position coordinate of the air conditioner and a coordinate axis; the second azimuth is an included angle between the position coordinate of the user and the coordinate axis.
Illustratively, the position coordinates of the air conditioner are the first position information (x6-x7, y6-y7), and the position coordinates of the user are the second position information (x8-x7, y8-y 7).
Referring to fig. 8, fig. 8 is a schematic diagram of determining a first azimuth angle and a second azimuth angle. In the rectangular coordinate system in fig. 8, the origin of coordinates represents the position coordinates of the fan. Point F represents the position coordinates (x8-x7, y8-y7) of the user relative to the fan, and angle b is a first azimuth angle of the air conditioner relative to the fan. Point E represents the position coordinates (x6-x7, y6-y7) of the air conditioner relative to the fan, and angle c is the second azimuth angle of the user relative to the fan.
In some embodiments, if the user has a position coordinate (-150, 300) with respect to the fan and the air conditioner has a position coordinate (300, 450) with respect to the fan, a first azimuth angle b of the air conditioner with respect to the fan can be calculated to be 56 ° according to a tangent formula of a triangle, and a second azimuth angle c of the user with respect to the fan can be calculated to be 180 ° -63 ° -117 °.
Specifically, the air supply range corresponding to the fan is determined according to the first azimuth angle b and the second azimuth angle c. For example, the overlapping portion of the first azimuth b and the second azimuth c may be used as the blowing range of the fan. From the above, it can be obtained that the first azimuth angle b is 56 °, the second azimuth angle c is 117 °, the blowing range can be set to [56 °, 117 ° ].
The air supply range corresponding to the fan can be determined according to the first azimuth angle and the second azimuth angle by calculating the first azimuth angle of the air conditioner relative to the fan and calculating the second azimuth angle of a user relative to the fan; the air supply range of the fan is determined, so that the fan can supply air in the blowing direction of the air conditioner, the cold air of the air conditioner can be dispersed, and the effect of quickly cooling the indoor space is achieved.
And step S40, sending a blowing instruction including the blowing direction to the air conditioner so that the air conditioner blows according to the blowing instruction.
Specifically, after determining a blowing direction of the air conditioner according to the first position information and the second position information, the blowing direction may be transmitted to the air conditioner; the air conditioner may blow air according to the blowing method.
In some embodiments, a blowing instruction including the blowing direction may be generated, and the blowing instruction is sent to the air conditioner through the communication module. For example, an air blowing instruction with an air blowing direction of 50 ° is generated, and the air blowing instruction is sent to the air conditioner through a bluetooth module in the fan.
In other embodiments, a blowing instruction including the blowing direction may be generated according to a request instruction of the air conditioner, and the blowing instruction is sent to the air conditioner through a communication module. For example, the air conditioner may send a request instruction to the fan at regular time, and the request instruction may be used to indicate a blowing direction; the fan can generate a blowing instruction with a blowing direction of 50 degrees according to the request instruction of the air conditioner, and the blowing instruction is sent to the air conditioner through a Bluetooth module in the fan.
And step S50, adjusting the rotation angle of the fan to supply air in the air supply range.
Specifically, the rotation angle of the fan is adjusted to perform directional air supply in the air supply range; or the rotation angle of the fan is adjusted to swing and supply air in the air supply range.
The rotation angle refers to an angle at which the fan head of the fan repeatedly rotates left and right or an angle at which the fan head repeatedly rotates up and down. When the air supply mode of the fan is swinging air supply, the rotation angle of the fan corresponds to the air supply range one by one; when the air supply mode of the fan is directional air supply, if the fan head of the fan is not in the air supply range, the rotation angle of the fan needs to be adjusted so that the fan head of the fan is in the air supply range.
In some embodiments, as shown in fig. 9, fig. 9 is a schematic view of a scene in which the rotation angle of the fan is adjusted to swing the air supply within the air supply range. If the air supply mode of the fan is swing air supply and the air supply range is [56 degrees and 117 degrees ], the rotation angle of the fan can be adjusted to [56 degrees and 117 degrees ] so that the fan head of the fan supplies air in the air supply range [56 degrees and 117 degrees ].
In other embodiments, as shown in fig. 10, fig. 10 is a schematic view of a scenario in which the rotation angle of the fan is adjusted to directionally blow air within the blowing range. If the air supply mode of the fan is directional air supply and the air supply range is [56 degrees and 117 degrees ], the rotation angle of the fan can be adjusted to the middle position of the air supply range; for example, the rotation angle is adjusted to 86 °, so that the fan head of the fan blows air at a position with a fixed angle of 86 °.
The fan and the air conditioner are combined to adjust the indoor temperature by adjusting the rotating angle of the fan to supply air in the air supply range, so that the indoor temperature is quickly reduced, and the user experience is improved.
Specifically, after the rotation angle of the fan is adjusted to supply air in the air supply range, the indoor temperature value of the air conditioner can be detected in real time; and if the temperature value is less than or equal to a preset temperature threshold value, stopping air supply of the air conditioner.
It can be understood that the air conditioner is provided with a temperature sensor which can detect the indoor temperature value in real time; the air conditioner can send the temperature value detected in real time to the fan through the communication module.
Illustratively, the preset temperature threshold may be 24 ℃.
In some examples, if the temperature value obtained by the air conditioner in real time to detect that the indoor temperature is 23 ℃ and the temperature value is less than the preset temperature threshold value of 24 ℃, a stop instruction for indicating stop of operation may be sent to the air conditioner, so that the air conditioner stops operating.
It can be understood that when the temperature value in the room is less than or equal to the preset temperature threshold, it indicates that the cooling in the room has been completed; at this time, the indoor temperature can be kept lower only by blowing with the fan, and the air conditioner does not need to be continuously started, thereby wasting resources.
According to the temperature adjusting method provided by the embodiment, the first position information of the air conditioner relative to the fan can be determined by acquiring the position information of the air conditioner and the position information of the fan; by acquiring the position information of the user, the second position information of the user relative to the fan can be determined, and the position information of the air conditioner and the user can be accurately obtained; the direction information of the user relative to the air conditioner is determined according to the first position information and the second position information, so that the air blowing direction of the air conditioner can be determined, air can be blown to the position of the user, and the comfort of the user in the air blowing process is improved; the air supply range of the fan can be determined by calculating a first azimuth angle of the air conditioner relative to the fan and a second azimuth angle of a user relative to the fan; the fan and the air conditioner are combined to adjust the indoor temperature by adjusting the rotating angle of the fan to supply air in the air supply range, so that the indoor temperature is quickly reduced, and the user experience is improved.
The embodiment of the application also provides a computer-readable storage medium, wherein a computer program is stored in the computer-readable storage medium, the computer program comprises program instructions, and the processor executes the program instructions to realize any temperature adjusting method provided by the embodiment of the application.
The computer readable storage medium may be an internal storage unit of the fan described in the foregoing embodiment, for example, a hard disk or a memory of the fan. The computer readable storage medium may also be an external storage device of the fan, such as a plug-in hard disk provided on the fan, a Smart Media Card (SMC), a Secure Digital Card (SD), a Flash memory Card (Flash Card), and the like.
