Referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of the air conditioner control method according to the present invention, and the air conditioner control method may be applied to the air conditioner.
In this embodiment, the air conditioner control method is applied to an air conditioner in communication connection with a breathing frequency detection module, and the air conditioner control method includes:
step S10, detecting the current respiratory rate of the user through the respiratory rate detection module;
in the prior art, an air conditioner generally has two modes of determining an operation parameter of the air conditioner according to a breathing frequency of a user at present, one mode is that a mapping relation between the breathing frequency and the operation parameter is preset, and the air conditioner is directly adjusted according to the operation parameter corresponding to the breathing frequency of the user after the breathing frequency of the user is obtained; and the other method is that the mapping relation between the activity state and the operation parameters is preset, after the respiratory frequency of the user is obtained, the activity state of the user is determined according to the respiratory frequency, and then the air conditioner is adjusted according to the operation parameters corresponding to the activity state of the user. In any scheme, the operation parameters are determined only according to the current respiratory rate of the user, and different users may be in a sleep state or a non-sleep state even if the users are in the same respiratory rate due to the difference of age, sex and health condition, and if the operation parameters of the air conditioner are adjusted only according to the current respiratory rate of the user, the adjustment of the parameters which are different from person to person cannot be performed, so that the fit of the operation condition of the air conditioner with the physical condition and activity condition of the user is low, and the user experience is poor.
In order to solve the technical problem that the air conditioner in the prior art cannot adjust the operation condition of the air conditioner according to the activity state of a human body, the embodiment of the invention provides an air conditioner control method, which aims to adjust the operation condition of the air conditioner according to the life characteristics of the breathing frequency of a user and the preset reference frequency of the user in the operation process of the air conditioner.
It is understood that the specific form of the breathing frequency detection module is not limited in this embodiment, and any device having a breathing frequency detection function may be used as the breathing frequency detection module, and the breathing frequency detection module may be a device provided in the air conditioner itself, or a device independent from the air conditioner, such as a breathing frequency detection module in a mobile terminal, where the breathing frequency refers to the number of breaths per unit time, and one fluctuation of the chest is one breath, i.e., one inspiration and one expiration.
Further, in one embodiment, the breathing frequency detection module may be a millimeter wave radar. Millimeter-wave radars (millimeter-wave radars) are radars that operate in the millimeter-wave band (millimeter wave) for detection. Generally, the millimeter wave refers to a wave in a frequency domain (wavelength is 1-10 mm) of 30-300 GHz. Compared with a centimeter-wave radar, the millimeter-wave radar has the characteristics of small volume, light weight and high spatial resolution. Compared with infrared, laser, television and other radars, the millimeter wave radar has strong capability of penetrating fog, smoke and dust, and has the characteristics of all weather (except rainy days) all day long. In addition, the millimeter wave radar is superior to other microwave radars in anti-interference and anti-stealth capabilities. The millimeter wave radar can distinguish and identify very small targets and can identify a plurality of targets simultaneously.
Further, if the respiratory frequency detection module is a millimeter wave radar, the step S10 includes: controlling the millimeter wave radar to transmit millimeter wave signals to a target object and receiving the millimeter wave signals returned by the target object; determining the phase difference between the phase when the millimeter wave signal is transmitted and the phase when the millimeter wave signal returns; and if the phase difference is not equal to the preset phase difference, extracting the current respiratory frequency of the user from the returned millimeter wave signal.
Specifically, after the millimeter-wave signal encounters a stationary object, the phase of the reflected millimeter-wave signal is the same as the phase of the millimeter-wave signal during transmission, but if the object is moving, the phase of the reflected millimeter-wave signal is different from the phase of the millimeter-wave signal during transmission, so that the phase difference between the transmitted wave and the reflected wave is not equal to a preset phase difference, wherein the preset phase difference may be selected to be 0. In this embodiment, because the breathing of the human body can cause the fluctuation and displacement of the thoracic cavity and the abdominal cavity, the millimeter wave radar transmits millimeter wave signals to the periphery of the room, when the phase difference between the phase of the reflected millimeter wave signals and the phase during transmission is not equal to the preset phase difference, it can be determined that the currently reflected millimeter waves are reflected by the human body, so that the current breathing frequency of the user can be extracted from the millimeter wave signals, when the phase difference between the phase of the reflected millimeter wave signals and the phase during transmission is equal to the preset phase difference, it can be determined that the currently reflected millimeter waves are reflected by objects such as walls, windows, furniture and the like, and it is not necessary to extract the current breathing frequency of the user from such millimeter wave signals, thereby avoiding invalid breathing frequency extraction, and improving the efficiency of breathing frequency extraction. In addition, traditional respiratory frequency measures, needs the user to wear the wearable equipment who is used for detecting user respiratory frequency next to the shin, and millimeter wave radar can realize contactless respiratory frequency monitoring under the condition of guaranteeing to detect the precision, promotes user's use comfort.
Step S20, determining the operation parameters of the air conditioner according to the current respiratory frequency and the preset reference frequency of the user;
and step S30, controlling the air conditioner to operate according to the operation parameters.
Before step S20, the method further includes: and if a preset reference frequency setting instruction is detected, detecting the respiratory frequency of the user through the respiratory frequency detection module to serve as the preset reference frequency.
Specifically, the preset reference frequency setting instruction may be actively triggered by the user, or may be automatically triggered by the air conditioner when the user starts a sleep mode of the air conditioner, which is not limited in this embodiment. The preset reference frequency reflects the breathing frequency of the user in a non-sleep state and a quiet state, and the user is usually in the non-sleep quiet state when actively triggering a preset reference frequency setting instruction or when starting a sleep mode of the air conditioner, so that the breathing frequency of the user can be detected as the preset reference frequency when the preset reference frequency setting instruction is detected.
Further, the preset reference frequency may be set in the following manner: if a preset reference frequency setting instruction is detected, acquiring the age of a user in the preset reference frequency setting instruction; and acquiring a corresponding age interval according to the age of the user, and determining a corresponding preset reference frequency according to the age interval. Different age intervals correspond to different preset reference frequencies. The preset reference frequency setting instruction may be triggered when a user actively sets the age of the user after the user starts the sleep mode of the air conditioner, or may be triggered when the user automatically identifies the age of the user through the age identification device when the user starts the sleep mode of the air conditioner, which is not specifically limited in this embodiment.
In this embodiment, after the current respiratory frequency of the user is obtained, the corresponding ratio interval is determined according to the current respiratory frequency and the preset reference frequency, that is, the state of the user can be determined, the corresponding operation parameter of the air conditioner is determined according to the state of the user, and the air conditioner is controlled to operate according to the operation parameter. The operation parameters of the air conditioner include, but are not limited to, at least one of the operation frequency of the compressor, the rotation speed of the fan and the angle of the air deflector.
In this embodiment, the current respiratory rate of the user is monitored by a respiratory rate detection module; determining the operating parameters of the air conditioner according to the current respiratory frequency and the preset reference frequency of the user; and controlling the air conditioner to operate according to the operation parameters. The breathing frequency of the user is monitored in the operation process of the air conditioner, the corresponding operation parameters are determined according to the breathing frequency of the user and the preset reference frequency of the user, the air conditioner is controlled to operate according to the operation parameters, and the operation parameters are determined according to two parameters reflecting the physical conditions of the user, so that the degree of conformity of the operation conditions of the air conditioner with the physical conditions and the activity states of the user can be improved, the adjustment of the air conditioner parameters which are different from person to person is more accurately and more intelligently realized, and the use experience of the user is improved.
Further, based on the first embodiment, a second embodiment of the air conditioner control method according to the present invention is provided, where in this embodiment, before the step S20, the method further includes:
step S201, determining that the user is in a sleep state according to the current respiratory frequency and a preset reference frequency, and executing the following steps: and determining the operating parameters of the air conditioner according to the current respiratory frequency and the preset reference frequency of the user.
The step S201 specifically includes: acquiring the ratio of the difference between a preset reference frequency and the current respiratory frequency to the preset reference frequency; and if the ratio is larger than a first preset ratio, determining that the user is in a sleep state.
In this embodiment, because the respiratory frequency of the user in the sleep state is different from the respiratory frequency of the user in the non-sleep state, and the respiratory frequency in the sleep state is usually lower than the respiratory frequency in the non-sleep state, when the user is in the sleep state, the ratio of the difference between the preset reference frequency and the current respiratory frequency to the preset reference frequency is greater than zero, at this time, the larger the ratio is, the more obvious the trend that the user is in the sleep state is indicated, in order to more accurately divide the sleep state from the non-sleep state, the first preset ratio is preset by the operation and maintenance staff, and if the ratio is greater than the first preset ratio, the user is determined to be in the sleep state. If the ratio is smaller than or equal to the first preset ratio, it is determined that the user is in the non-sleep state, and the ratio when the user is in the non-sleep state may be smaller than zero.
It can be understood that if the user is in the non-sleep state, the operation parameters of the air conditioner are not adjusted, and the air conditioner is controlled to operate according to the existing operation parameters.

Therefore, after the current respiratory frequency of the user is obtained, the ratio of the difference between the preset reference frequency and the current respiratory frequency to the preset reference frequency can be calculated, the target ratio interval to which the user belongs is determined according to the ratio, and then the corresponding operation parameter is determined according to the target ratio interval and is used as the operation parameter of the air conditioner.

The ratio interval between the initial sleep stage and the final sleep stage is the same and is the first ratio interval, so that if the target ratio interval is the first ratio interval, the sleep stage to which the current respiratory frequency belongs needs to be further judged according to the variation trend of the ratio, and the corresponding operation parameter is determined; the ratio interval of the deep sleep period is a second ratio interval.
Wherein, the first ratio interval is (A, B), the value range of A is 0.2-0.35, the value range of B is 0.2-0.35, and A is less than B.
