Referring to FIG. 2, in the first embodiment, the monitoring method of the sleep stage includes:

Step S10: obtaining a change rate of the motion amplitude of the user by using a radar sensor in real time or timing;

In this embodiment, a radar sensor is disposed on the air conditioner, and the distance between the user and the air conditioner is obtained by the radar sensor in real time or at a time to obtain the user's operating amplitude change rate according to the distance. Specifically, calculating a difference between the acquired distance and the last acquired distance, using the difference as the motion amplitude of the user, and calculating a quotient between the difference and the last acquired distance. The quotient value is taken as the rate of change of the motion amplitude.

It should be noted that the infrared and ultrasonic technologies in the prior art can only detect users in a straight line direction, and cannot detect the distance between the user and the air conditioner, and the radar sensor realizes a 360° dead angle detection user, and detects the user and the air conditioner. The distance between the devices. Specifically, the radar sensor detects the user using electromagnetic waves and receives the echo of the user, thereby obtaining the distance between the user and the air conditioner. It should be noted that the radar sensor detects the human body through breathing and heart rate. If there are multiple users in the environment of the air conditioner, the echoes of different users may also differ due to the difference in respiratory frequency and heartbeat frequency of different users.

In this embodiment, the position and the number of the radar sensors can be set according to actual applications, which is not specifically limited in this application.

The execution subject of this embodiment is an air conditioner or a server. For example, when the execution body is an air conditioner, the air conditioner acquires the distance between the user and the air conditioner through the radar sensor, and calculates the movement amplitude change rate of the user according to the distance; when the execution subject is the server, the radar sensor acquires the user and the air conditioner. The distance between the two is sent to the server, so that the server calculates the rate of change of the user's motion amplitude according to the distance and feeds back.

Step S20: Determine a sleep stage of the user according to the motion amplitude change rate.

In this embodiment, the user has multiple sleep stages in the sleep state, such as the waking period, the sleep period, the shallow sleep period, the deep sleep period, and the REM before going to bed. The rate of change of the motion amplitude is different for different sleep stages, so The user's sleep stage can be determined according to the rate of change of the motion amplitude.

For example, when the user is in a shallow sleep period, a deep sleep period, and a REM, the rate of change in the movement range of the shallow sleep period is about 20%; the rate of change in the exercise range during the deep sleep period is about 10%; and the rate of change in the movement amplitude of the REM is 30%. Left and right, so the user's sleep stage can be determined by the rate of change of the motion amplitude.

It should be noted that the sleep stage of the user may also be determined according to the respiratory rate change rate and the motion amplitude change rate. Specifically, the motion amplitude change rate and the respiratory frequency change rate of the user are acquired by the radar sensor in real time or timing, and the sleep phase is determined according to the motion amplitude change rate and the respiratory frequency change rate. Wherein, the radar sensor acquires a breathing interval of a user in an environment where the air conditioner is located, so that the air conditioner or the server calculates the breathing frequency according to the breathing interval. The calculation method of the respiratory rate change rate is similar to the calculation method of the motion amplitude change rate, and the difference between the acquired respiratory frequency and the last acquired respiratory frequency is calculated, and the difference is calculated and the last acquired The quotient between the respiratory frequencies, which is the rate of change of the respiratory rate.

For example, when the user is in the waking period and during the sleep period, the rate of change in the awake period is about 50%, the rate of change in respiratory rate is about 15%; the rate of change in the range of movement during sleep is about 45%, and the rate of change in respiratory rate is 8 About %, so the sleep stage of the user can be determined by the rate of change of the respiratory rate and the rate of change of the range of motion.

In the first embodiment, the rate of change of the motion amplitude of the user is acquired by the radar sensor in real time or timing, and the sleep stage of the user is determined according to the rate of change of the motion amplitude. In this way, the radar sensor determines the sleep stage in which the user is located, and has the advantages of not affecting the user's sleep, affecting the user's privacy, and high precision.

In the second embodiment, as shown in FIG. 3, based on the embodiment shown in FIG. 2, the step of determining the sleep stage of the user according to the change rate of the motion amplitude includes:

Step S21: acquiring the respiratory rate change rate of the user by using the radar sensor in real time or timing;

Step S22, determining the sleep stage according to the respiratory rate change rate and the motion amplitude change rate.

In this embodiment, a radar sensor is disposed on the air conditioner, and the breathing interval of the user in the environment where the air conditioner is located is obtained by the radar sensor in real time or periodically, so that the air conditioner or the server calculates the breathing frequency according to the breathing interval. At the same time, the radar sensor acquires the distance between the user and the air conditioner in real time or timing to obtain the user's operating amplitude change rate according to the distance. Specifically, calculating a difference between the acquired respiratory frequency and the last acquired respiratory frequency, and calculating a quotient between the difference and the last acquired respiratory frequency, using the quotient as a breath Frequency change rate. It should be noted that the respiratory rate change rate is not limited to the above calculation method, and may be set according to actual conditions.

For example, the rate of change of the user's movement during the waking period is about 50%, and the rate of change of the respiratory rate is about 15%; the rate of change of the movement of the user during the sleep period is about 45%, and the rate of change of the respiratory rate is about 8%; The rate of change in the movement range of the shallow sleep period is about 20%, and the rate of change of the respiratory rate is about 5%; the rate of change of the movement amplitude of the user during the deep sleep period is about 10%, and the rate of change of the respiratory rate is about 2%; the user is in the REM The rate of change of motion amplitude is about 30%, and the rate of change of respiratory rate is about 35%. Therefore, the sleep stage of the user can be determined by the rate of change of respiratory rate and the rate of change of motion amplitude.

In the second embodiment, the sleep phase is determined based on the respiratory rate change rate and the rate of change of the exercise amplitude, thus ensuring the accuracy of the sleep phase acquisition.

In the third embodiment, as shown in FIG. 4, after determining the sleep stage of the user according to the change rate of the motion amplitude, the method further includes:

At least one of the air supply types includes direct blow prevention, no wind feeling, soft wind feeling, and the like.

Specifically, the operation parameters corresponding to the respective sleep stages are set in advance, and when the sleep stage in which the user is currently located is detected, the air conditioner is controlled to operate according to the operation parameters corresponding to the sleep stage. It should be noted that the preset duration of each sleep stage is preset, and when the sleep duration of a certain sleep stage is detected to be too short or too long, the operating parameters can be automatically adjusted to ensure the user's sleep quality. For example, when it is detected that the duration of the user's sleep period is greater than the preset duration, the running parameters corresponding to the deep sleep period are automatically run to help the user quickly enter the deep sleep period.

In the third embodiment, the operating parameters corresponding to the sleep phase are acquired, and the air conditioner is controlled to operate according to the operating parameters, thus ensuring the sleep quality of the user.

In the fourth embodiment, as shown in FIG. 5, on the basis of the foregoing embodiment shown in FIG. 2 to FIG. 4, after the acquiring the operating parameter corresponding to the sleep phase, the method further includes:

Step S401: Acquire a priority of the sleep stage when acquiring a plurality of operation parameters corresponding to the sleep stage;

Step S402: Control the air conditioner to operate according to an operation parameter corresponding to a sleep stage with the highest priority.

In this embodiment, the priority of the sleep stage is set in advance so that a plurality of users are in a sleep state in the environment where the air conditioner is located, but when the plurality of users are in different sleep stages, the air conditioner is controlled according to the sleep stage with the highest priority. Run the parameter to run. For example, setting the deep sleep period has a higher priority than the light sleep period, and when the deep sleep period and the shallow sleep period are detected, the control air conditioner operates according to the operating parameters corresponding to the deep sleep period.

In this embodiment, the priority of the user may also be set in advance, so that when multiple users in the environment where the air conditioner is located are in a sleep state, and the plurality of users are in different sleep stages, the air conditioner is controlled according to the user with the highest priority. The operating parameters corresponding to the sleep phase are run. The user performs a binding operation with the air conditioner in advance. During the binding operation, the radar sensor acquires and records the respiratory frequency of the user, and creates user information for the user, and the user information includes priorities. For example, setting the priority of the elderly in the family is the highest, and the second is the child. The priority of the adult is the lowest. When there are elderly, adults and children in the room, the operation parameters corresponding to the sleep stage of the elderly are given priority.

In the fourth embodiment, when the operation parameters corresponding to the plurality of sleep stages are acquired, the priority of the sleep stage is acquired, and the air conditioner is controlled to operate according to the operation parameter corresponding to the sleep stage with the highest priority.
