[0018] According to the following detailed description of the specific embodiments of the present invention in conjunction with the drawings, those skilled in the art will more clearly understand the above and other objects, advantages and features of the present invention. Description of the Drawings

[0019] Some specific embodiments of the present invention will be described in detail hereinafter with reference to the accompanying drawings in an illustrative rather than restrictive manner. The same reference numerals in the drawings denote the same or similar components or parts. Those skilled in the art should understand that these drawings are not necessarily drawn to scale. In the drawings:

[0022] Figure 3 is a schematic block diagram of a controller for an air conditioner according to an embodiment of the present invention; and

[0023] Figure 4 is a schematic diagram of a machine-readable storage medium according to an embodiment of the present invention. Detailed Embodiments

[0024] This embodiment first provides a control method for an air conditioner, which can automatically adjust the set temperature of the air conditioner according to the actual situation, improve the intelligence level of the air conditioner, save the time and energy of users, and enhance the user experience. Figure 1 is a schematic diagram of a control method for an air conditioner according to an embodiment of the present invention. As Figure 1 shown, the control method for the air conditioner may include the following steps:

[0025] Step S102, obtaining the set temperature of the air conditioner when the air conditioner is turned on;

[0026] Step S104, monitoring the transmission frequency and reception frequency of the WiFi signal to determine the observation speed of users in the indoor environment;

[0027] Step S106, determining the current state of the user according to the observation speed;

[0028] Step S108, adjusting the set temperature according to the current state.

[0029] In the above steps, obtaining the set temperature of the air conditioner in step S102 may specifically include: receiving the set temperature set by the user through the display device, voice device, remote control or mobile terminal bound to the air conditioner of the air conditioner. And, the user can also send a trigger signal to turn on the air conditioner through the display device, voice device, remote control or mobile terminal bound to the air conditioner of the air conditioner, and control the air conditioner to turn on after receiving the trigger signal to turn on the air conditioner. Among them, the mobile terminal may be a portable intelligent device, such as a smart phone, a tablet computer, etc.

[0030] It should be noted that after obtaining the set temperature of the air conditioner when the air conditioner is turned on, the user may not be next to the air conditioner, or the user may be in a moving state, that is, it is inconvenient for the user to manually operate and adjust the set temperature of the air conditioner subsequently. The control method of the air conditioner in this embodiment can automatically adjust the set temperature of the air conditioner according to the actual situation, improve the intelligence level of the air conditioner, save the user's time and energy, and improve the user's experience.

[0031] After obtaining the set temperature of the air conditioner when the air conditioner is turned on, step S104 can be executed to monitor the transmission frequency and reception frequency of the WiFi signal to determine the observed speed of the user in the indoor environment. In a specific embodiment, the transmission frequency can be actively generated by an oscillator, a signal source or frequency synthesis technology, and the accuracy is determined by the oscillation element and circuit design. The reception frequency can be passively measured by relying on technologies such as spectrum analysis, mixing, and counting, and effective frequency components need to be extracted by combining signal processing algorithms.

[0032] Moreover, the step of determining the observed speed of the user in the indoor environment can specifically include: calculating the difference between the reception frequency and the transmission frequency to obtain the frequency shift; using the formula to calculate the observed speed, where Δf is the frequency shift, f is the transmission frequency, v is the propagation speed of the WiFi signal in the medium, v0 is the observed speed, and t is the set time.

[0033] The above formula is mainly obtained based on the Doppler effect. It should be noted that when the user moves towards the wave source of the WiFi signal, the observed speed v0 is greater than 0, and the reception frequency is greater than the transmission frequency. When the user moves away from the wave source of the WiFi signal, the observed speed v0 is less than 0, and the reception frequency is less than the transmission frequency. However, the positive or negative of the observed speed v0 only represents the moving direction of the user towards or away from the wave source of the WiFi signal, and the absolute value of the observed speed v0 represents the speed of the user's specific observed speed.

[0034] Step S106 determines the current state of the user according to the observed speed. Specifically, the current state of the user can include a moving state and a stationary state. In a preferred embodiment, the step of determining the current state of the user according to the observed speed includes: calculating the speed difference between the absolute value of the observed speed and the set speed; and determining the current state according to the speed difference. Among them, the set speed is a positive number. And, the step of determining the current state according to the speed difference includes: judging whether the speed difference is greater than or equal to 0; and if so, determining the current state as the moving state. In the case where the speed difference is less than 0, the current state is determined as the stationary state.

[0035] When the absolute value of the observed speed minus the set speed is greater than or equal to 0, it indicates that the absolute value of the observed speed is greater than or equal to the set speed. It can be considered that the user's movement relative to the WiFi signal source is relatively intense. Therefore, it can be determined that the user's current state is a moving state. When the absolute value of the observed speed minus the set speed is less than 0, it indicates that the absolute value of the observed speed is less than the set speed. It can be considered that the user's movement relative to the WiFi signal source is relatively slight or completely stationary. Therefore, it can be determined that the user's current state is a stationary state.

[0036] After determining the user's current state based on the observed speed in step S106, step S108 can be executed to adjust the set temperature according to the current state. In a specific embodiment, the step of adjusting the set temperature according to the current state includes: when the current state is a moving state, reducing the set temperature; when the current state is a stationary state, increasing the set temperature. Moreover, the greater the absolute value of the speed difference, the greater the amplitude of increasing or decreasing the set temperature.

[0037] Determining the user's current state based on the observed speed and then adjusting the set temperature of the air conditioner according to the current state can enable the air conditioner to operate at a set temperature that conforms to the user's current state, fully ensuring that the set temperature of the air conditioner meets the current actual situation, satisfying the user's usage requirements, and enhancing the user's usage experience.

[0038] In summary, the control method of the air conditioner in this embodiment, by obtaining the set temperature of the air conditioner when the air conditioner is turned on, monitoring the transmission frequency and reception frequency of the WiFi signal to determine the observed speed of the user in the indoor environment, determining the user's current state based on the observed speed, and adjusting the set temperature according to the current state, can automatically adjust the set temperature of the air conditioner according to the actual situation, improve the intelligence level of the air conditioner, save the user's time and energy, and enhance the user's usage experience.

[0039] In some alternative embodiments, higher technical effects can be achieved by further optimizing and configuring the above steps. The following details the control method of the air conditioner in this embodiment in combination with the introduction of an alternative execution process of this embodiment. This embodiment is only an example of the execution process. In specific implementation, the execution order and operating conditions of some steps can be modified according to specific implementation requirements. Figure 2 It is a detailed flowchart of the control method of the air conditioner according to an embodiment of the present invention. The control method of the air conditioner includes the following steps:

[0040] Step S202, obtain the set temperature of the air conditioner when the air conditioner is turned on;

[0041] Step S204: Monitor the transmission frequency and reception frequency of the WiFi signal to determine the observed speed of the user in the indoor environment;

[0042] Step S206: Calculate the speed difference between the absolute value of the observed speed and the set speed;

[0043] Step S208: Determine whether the speed difference is greater than or equal to 0. If so, execute Step S210; if not, execute Step S214;

[0044] Step S210: Determine the current state as the moving state;

[0045] Step S212: Lower the set temperature;

[0046] Step S214: Determine the current state as the stationary state;

[0047] Step S216: Raise the set temperature.

[0048] In the above steps, Step S202 for obtaining the set temperature of the air conditioner may specifically include: receiving the set temperature set by the user through the display device, voice device, remote control or mobile terminal bound to the air conditioner of the air conditioner. And, the user can also send a trigger signal to turn on the air conditioner through the display device, voice device, remote control or mobile terminal bound to the air conditioner, and control the air conditioner to turn on after receiving the trigger signal to turn on the air conditioner. Among them, the mobile terminal may be a portable intelligent device, such as a smart phone, a tablet computer, etc.

[0049] It should be noted that after obtaining the set temperature of the air conditioner when the air conditioner is turned on, the user may not be next to the air conditioner, or the user may be in a moving state, that is, it is inconvenient for the user to manually operate and adjust the set temperature of the air conditioner subsequently. The control method of the air conditioner adopting this embodiment can automatically adjust the set temperature of the air conditioner according to the actual situation, improve the intelligence level of the air conditioner, save the time and energy of the user, and improve the user experience.

[0050] Step S204 monitors the transmission frequency and reception frequency of the WiFi signal to determine the observed speed of the user in the indoor environment. In a specific embodiment, the transmission frequency can be actively generated by an oscillator, a signal source or frequency synthesis technology, and the accuracy is determined by the oscillation element and circuit design. The reception frequency can then be measured passively relying on technologies such as spectrum analysis, mixing, and counting, and effective frequency components need to be extracted in combination with signal processing algorithms.

[0051] And, the step of determining the observed speed of the user in the indoor environment may specifically include: calculating the difference between the reception frequency and the transmission frequency to obtain the frequency shift; using the formula The observed velocity is calculated, where Δf is the frequency shift, f is the transmission frequency, v is the propagation speed of the WiFi signal in the medium, v0 is the observed velocity, and t is the set time.

[0052] The above formula is primarily based on the Doppler effect. It's important to note that when the user is moving toward the WiFi signal source, the observed speed v0 is greater than 0, and the receiving frequency is greater than the transmitting frequency. When the user is moving away from the WiFi signal source, the observed speed v0 is less than 0, and the receiving frequency is less than the transmitting frequency. However, the positive or negative value of the observed speed v0 only represents the direction of the user's movement toward or away from the WiFi signal source; the absolute value of the observed speed v0 represents the user's specific observed speed.

[0053] The source of WiFi signals is an electronic device with radio frequency transmission capabilities. Its core function is to achieve wireless transmission through the conversion of digital signals, radio frequency signals, and electromagnetic waves. In a specific embodiment, the source of WiFi signals can be devices such as wireless routers and wireless access points (APs). WiFi signals are essentially electromagnetic waves, and their propagation speed in different media is primarily determined by the relative dielectric constant and relative magnetic permeability of the medium.

[0054] According to electromagnetic theory, the formula for the propagation speed of electromagnetic waves in a medium is: Where c is the speed of light in vacuum, which is approximately 3×10 8 m / s, ε r is the relative dielectric constant of the medium, which characterizes the response of the medium to the electric field. r is the relative magnetic permeability of the medium, which characterizes the medium's response to the magnetic field. Since the relative dielectric constant and relative magnetic permeability of the medium involved in the WiFi signal, such as air, are both approximately 1, the propagation speed of the WiFi signal in the air is generally close to 3×10 8 m / s. The set time t can be preset according to actual conditions.

[0055] The user's current state may include a moving state and a stationary state, and the user's current state can be determined based on the user's observed speed. Specifically, after determining the user's observed speed in the indoor environment in step S204, steps S206 and S208 may be executed to calculate the speed difference between the absolute value of the observed speed and the set speed, and determine whether the speed difference is greater than or equal to 0. If the determination result in step S208 is yes, i.e., the speed difference between the absolute value of the observed speed and the set speed is greater than or equal to 0, step S210 is executed to determine that the current state is a moving state.

[0056] Among them, the set speed is a positive number. When the absolute value of the observed speed minus the set speed is greater than or equal to 0, it indicates that the absolute value of the observed speed is greater than or equal to the set speed. It can be considered that the user's movement relative to the WiFi signal source is relatively intense. Therefore, it can be determined that the user's current state is a moving state.

[0057] After determining that the current state is a moving state in step S210, step S212 can be executed to lower the set temperature. Since the user's current state is a moving state, they may feel hotter. Appropriately lowering the set temperature can enable the air conditioner to increase the cooling capacity or reduce the heating capacity. Moreover, the greater the absolute value of the speed difference, the greater the amplitude of lowering the set temperature. This is because when the absolute value of the difference between the observed speed and the set speed is greater than or equal to 0, the greater the absolute value of the speed difference, the more intense the user's movement state, the hotter they feel, and the more necessary it is to significantly lower the set temperature, increase the cooling capacity for cooling, or reduce the heating capacity, thereby improving the comfort level of the user in the moving state.

[0058] If the judgment result in step S208 is negative, that is, when the absolute value of the difference between the observed speed and the set speed is less than 0, step S214 is executed to determine that the current state is a stationary state. The absolute value of the difference between the observed speed and the set speed being less than 0 indicates that the absolute value of the observed speed is less than the set speed. It can be considered that the user's movement relative to the WiFi signal source is relatively slight or completely stationary. Therefore, it can be determined that the user's current state is a stationary state.

[0059] After determining that the current state is a stationary state in step S214, step S216 can be executed to raise the set temperature. Since the user's current state is a stationary state, they are likely to feel colder after remaining still for a long time, especially when the user is in a sleeping state and completely stationary, they are more likely to feel cold and prone to catching a cold. Therefore, the set temperature can be appropriately raised to enable the air conditioner to increase the heating capacity or reduce the cooling capacity. Moreover, the greater the absolute value of the speed difference, the greater the amplitude of raising the set temperature. This is because when the absolute value of the difference between the observed speed and the set speed is less than 0, the greater the absolute value of the speed difference, the more stationary the user's stationary state, the more likely they are to feel cool, and the more necessary it is to significantly raise the set temperature, increase the heating capacity for warming, or reduce the cooling capacity, thereby improving the comfort level of the user in the stationary state.

[0060] It should be noted that the user's current state is a stationary state, which can be either a completely motionless state or a state of slight movement. The classification of slight movement and vigorous movement can be achieved by specifically setting the speed in step S206. If the determination of vigorous movement is strict, requiring the user to move quickly, then the set speed can be set higher; if the determination of vigorous movement is more relaxed, then the set speed can be set lower.

[0061] In summary, the control method of the air conditioner in this embodiment lowers the set temperature when the current state is a moving state; and increases the set temperature when the current state is a stationary state. The larger the absolute value of the speed difference, the greater the amplitude of increasing or decreasing the set temperature. This can make the set temperature of the air conditioner conform to the current actual situation, fully meet the user's usage needs, and further enhance the user's usage experience.

[0062] This embodiment further provides an air conditioner, which may include a controller 300 .
