Figure 1 is a schematic flowchart of an auxiliary sleep control method for an air conditioner provided by this application. As shown in Figure 1, the auxiliary sleep control method for air conditioning provided by the embodiment of the present application includes: Step 101: Obtain the heart rate change curve of each individual based on the heart rate information of each individual monitored by the radar module.

It should be noted that the execution subject of the auxiliary sleep control method for air conditioners provided by the embodiments of the present application is the auxiliary sleep control device for air conditioners.

The application scenario of the auxiliary sleep control method for air conditioners provided by the embodiments of the present application is that after the user activates the default working mode of the air conditioning system (such as cooling mode, heating mode, etc.), the radar module provides real-time feedback of the space where the air conditioner is located. It uses human body heart rate information in the room to monitor the sleep status of indoor users to make adaptive adjustments to the wind speed of the air conditioner.

Among them, the radar module periodically collects the heart rate information of all individuals in the room at specified time intervals, and sends the heart rate information to the auxiliary sleep control device of the air conditioner. The embodiments of this application do not specifically limit the working cycle of the radar module.

Optionally, the radar module can perform collection operations in the default working cycle.

Optionally, the user can issue a cycle change command, so that the radar module accepts and responds to the command and changes the working cycle to the cycle indicated by the command to perform the collection operation.

It should be noted that before step 101, the user needs to send an activation command through the transmission medium to activate the working mode of the air conditioner, so that the indoor unit of the air conditioner runs at the default wind speed of this mode, and the outdoor unit runs at the default frequency of this mode. .

Optionally, the user can transmit activation instructions through the control device and use wireless communication between the control device and the air conditioner to initialize the working mode of the air conditioning system.

Optionally, the user can issue an activation instruction through voice interaction, and the air conditioner receives the activation instruction, performs voice recognition, and initializes the working mode.

Specifically, in step 101, after the air conditioner starts the working mode, the auxiliary sleep control device of the air conditioner receives the real-time heart rate information collected by the radar module for each individual in the room, and uses the real-time heart rate information and collection of each individual. Time to construct a heart rate change curve corresponding to the individual.

The embodiments of this application do not specifically limit the type and quantity of radar sensing devices in the radar module.

For example, the radar module may include a lidar, infrared sensor, etc.

Optionally, since the horizontal detection range of millimeter wave radar can reach ±75°, the vertical detection range is ±40°, the detection distance can reach 8 meters, the distance output accuracy can reach 0.1 meters, and the angle output accuracy can reach 1°, and It does not involve privacy issues, is not affected by light, and its response speed is also faster. Therefore, the auxiliary sleep control device of the air conditioner uses the heart rate information collected in real time by the millimeter wave radar as the current heart rate of the individual user.

For example, the radar module may include multiple types of sensing elements such as millimeter-wave radar, lidar, and infrared sensors. The air-conditioning and dehumidification control device uses the heart rate data collected by each sensing element to add and average the data to characterize the Current heart rate information.

Step 102: When it is determined that the heart rate variation curve of any individual is consistent with the first state, control the air conditioner to switch to the sleep mode.

The first state is that the heart rate information is in a downward trend during the current monitoring period, and the decrease is greater than or equal to the first preset threshold.

It should be noted that heart rate refers to the number of heartbeats per minute. The heart rate of a normal person in a quiet state is generally 60-100 beats/minute. Factors such as activity, anger, excitement, fever, drinking coffee, strong tea, etc. can cause heart rate accelerate. When a person is sleeping, the heart rate will also change to a certain extent. In the first minute, it is about 64 to 84 times. After entering a state of deep sleep, it is only about 45 to 50 times a minute.

The first state refers to the heart rate information collected by the radar module in multiple consecutive working cycles under the current monitoring cycle, which decreases with the increase of collection time, and the decrease in heart rate information is greater than or equal to the first preset threshold. This The application embodiment does not specifically limit the value of the first preset threshold.

For example, the first preset threshold may be 10 times to avoid misjudgment caused by a disease outbreak corresponding to a sudden drop in the user's individual heart rate.

Specifically, in step 102, the auxiliary sleep control device of the air conditioner analyzes the heart rate change curves of all individuals, and if it is determined that the change trend of the heart rate change curves of the individuals is consistent with the first state, that is, in the current indoor space, If at least one individual user is in a sleep state, the air conditioner is controlled to switch from the current working mode to the sleep mode for operation.

Step 103: Based on the current heart rate and the target inflection point in the individual heart rate change curve, control the air conditioner to adjust the wind speed of the indoor unit in the sleep mode.

Among them, the target inflection point is determined based on the heart rate information in the current monitoring period.

It should be noted that the target inflection point is an inflection point determined by a section of the curve corresponding to the current monitoring period in the heart rate change curve of the first state to represent the critical value of the heart rate when the user enters the sleep state.

Specifically, in step 103, the auxiliary sleep control device of the air conditioner extracts the current heart rate and the target inflection point under the current monitoring period from the heart rate change curve that conforms to the first state, and determines what degree of sleep state the individual user is in, so as to Control the air conditioner to adaptively adjust the wind speed of the indoor unit in sleep mode.

The number of heart rate change curves that conform to the first state may be one or more, that is, there may be one or more user individuals in a sleeping state in the current indoor space.

Optionally, when there is only one heart rate change curve that conforms to the first state, the current heart rate and the target inflection point are extracted from the heart rate change curve, and the degree of sleep state of the individual user is determined to adjust the indoor unit. The wind speed can maintain the indoor temperature in a range suitable for sleeping.

Optionally, when the number of heart rate change curves that conform to the first state can be multiple, extract their respective current heart rates from multiple different heart rate change curves corresponding to multiple individual users, and perform a weighted average as the overall current heart rate. heart rate, and select the maximum value from the target inflection points of multiple different heart rate change curves as the overall target inflection point. Using the overall current heart rate and the overall target inflection point, the average level of the horizontal status of multiple individual users is determined to adjust the indoor unit. The wind speed can maintain the indoor temperature in a range suitable for sleeping.

The embodiment of the present application monitors individual heart rate in real time based on the radar module and obtains the heart rate change curve. When it is determined that the heart rate change curve conforms to the first state, when the air conditioner switches to sleep mode, the current heart rate and the target inflection point in the heart rate change curve are used. , decide to adjust the wind speed of the indoor unit. It realizes sleep state analysis based on individual heart rate changes, and adaptively adjusts the wind speed of the indoor unit to maintain the room temperature in sleep mode within the range corresponding to the actual sleep state, improves room temperature control accuracy, and enhances user experience.

Based on any of the above embodiments, based on the current heart rate and the target inflection point in the heart rate change curve, controlling the air conditioner to adjust the wind speed of the indoor unit in the sleep mode includes: adjusting the heart rate value and the maximum heart rate value corresponding to the target inflection point as follows: The interval at the starting point is divided into intervals to obtain at least two heart rate sub-intervals.

Among them, the maximum heart rate value is the maximum value of the heart rate information in the current monitoring period, and any heart rate sub-range is preset with a wind speed control gear.

It should be noted that the maximum heart rate value refers to the maximum value among all the heart rate information in the heart rate change curve during the current monitoring period.

Specifically, in step 103, the auxiliary sleep control device of the air conditioner uses the heart rate value D and the maximum heart rate value T corresponding to the target inflection point as the starting point and end point of the threshold interval respectively, and divides n points in the threshold interval to obtain n+1 heart rate sub-intervals.

Among them, n is a positive integer greater than or equal to 1. Each heart rate sub-interval corresponds to a wind speed control gear.

Get the target heart rate sub-range corresponding to the current heart rate to adjust the wind speed of the indoor unit to the target wind speed.

Among them, the target heart rate sub-interval is one of all heart rate sub-intervals; the target wind speed is the wind speed of the indoor unit when the wind speed control gear is the target wind speed control gear.

Specifically, the auxiliary sleep control device of the air conditioner uses the heart rate sub-interval where the current heart rate is located as the target heart rate sub-interval, and uses the wind speed control gear corresponding to the heart rate sub-interval as the target wind speed control gear, and controls the indoor unit to adjust the speed to The wind speed generated at the speed indicated by the target wind speed control gear is used as the target wind speed for air supply in sleep mode.

As an example, a specific implementation method for adjusting wind speed is given:

Divide the threshold interval formed by the heart rate value D corresponding to the target inflection point and the maximum heart rate value T into four heart rate sub-intervals:

First heart rate sub-interval

The corresponding wind speed control gear is the indoor unit speed of 200 rpm.

Second heart rate sub-interval

The corresponding wind speed control gear is the indoor unit speed of 400 rpm.

The third heart rate sub-range

The corresponding wind speed control gear is the indoor unit speed of 600 rpm.

The fourth heart rate sub-range

The corresponding wind speed control gear is the indoor unit speed of 800 rpm.

If the current heart rate is in the first heart rate sub-range, it means that the user is in a deep sleep state, and the corresponding indoor unit is controlled to supply air at a speed of 200 rpm.

It can be understood that the n points within the threshold interval can also be set at unequal intervals to divide multiple unequal heart rate sub-intervals.

The embodiment of the present application performs gradient division based on the heart rate value and the maximum heart rate value corresponding to the target inflection point, and determines the target heart rate sub-interval corresponding to the current heart rate, so that the wind speed of the indoor unit is adjusted to the corresponding target wind speed at this level, achieving the goal according to The actual heart rate quantitatively adjusts the wind speed to improve the control accuracy and efficiency of the wind speed, while also taking into account energy efficiency and saving, and optimizing the user experience.

Based on any of the above embodiments, based on the current heart rate and the target inflection point in the heart rate change curve, controlling the air conditioner to adjust the wind speed of the indoor unit in the sleep mode includes: determining the maximum heart rate value in the heart rate change curve and the target inflection point. Corresponding target heart rate value.

Specifically, in step 103, the auxiliary sleep control device of the air conditioner obtains the maximum heart rate value T in this cycle from a section of the heart rate change curve corresponding to the current monitoring cycle, and extracts the target heart rate value corresponding to the target inflection point. D.

Determine the target rotation speed of the indoor unit based on the current heart rate, maximum heart rate value and target heart rate value.

Specifically, the auxiliary sleep control device of the air conditioner calculates the current heart rate, the maximum heart rate value T and the target heart rate value D using the corresponding mathematical model to obtain the target rotation speed of the indoor unit.

The embodiment of the present application does not specifically limit the mathematical model of the indoor unit target speed.

Preferably, the mathematical model of the indoor unit target speed is proportional to the linear correlation, and its calculation formula is

Among them, V is the target speed of the indoor unit, and t is the current heart rate.

The wind speed of the indoor unit at the target speed is the target wind speed.

Specifically, the auxiliary sleep control device of the air conditioner encapsulates the target rotation speed into a control instruction, so that the indoor unit receives and responds to the control instruction to supply air to the room at the target wind speed.

The embodiment of the present application performs corresponding calculations based on the target heart rate value and the maximum heart rate value corresponding to the target inflection point, combined with the current heart rate, to obtain the target rotation speed of the indoor unit, so that the indoor unit adjusts the wind speed to the target wind speed under the action of the target rotation speed, achieving In order to quantitatively adjust the wind speed according to the actual heart rate, it improves the control accuracy and efficiency of the wind speed, while also taking into account energy efficiency and saving, and optimizing the user experience.

Based on any of the above embodiments, before obtaining the heart rate change curve of each individual based on the heart rate information of each individual monitored by the radar module, it also includes: obtaining the current scene information based on the human posture information fed back by the radar module. .

Specifically, before step 101, the auxiliary sleep control device of the air conditioner must first receive the human body posture information fed back by the radar module, perform contour recognition and feature extraction, and use the currently performed action characteristics identified for each individual in the room as the current scene information.

When it is determined that the current scene information is that any individual in the room is lying flat, the heart rate change curve of each individual is obtained based on the heart rate information.

Specifically, the auxiliary sleep control device of the air conditioner analyzes the action characteristics of each individual in the current scene information. If the analysis result is that one or more individuals are lying down, it means that there are user individuals in the current room who have a tendency to sleep. , then activate the heart rate monitoring function of the radar module to receive the heart rate information of each individual fed back by the radar module, and integrate it into the heart rate change curve corresponding to each individual.

If the analysis result is that there is no individual lying down, it means that there is no individual user in the current room who is prone to sleep, and the heart rate monitoring function of the radar module will not be activated, and the current working mode of the air conditioner will be maintained.

The embodiment of this application depicts the current scene information based on the human body posture information fed back by the radar module, and monitors the change trend of the heart rate information through decision-making based on the current scene information, thereby realizing the analysis of the user's action intention based on the actual scene, and through the individual's heart rate changes. Adaptively adjust the wind speed of the indoor unit in sleep mode to maintain the room temperature in the range corresponding to the actual sleep state, improve the control accuracy of room temperature, and enhance the user experience.

Based on any of the above embodiments, after controlling the air conditioner to switch to the sleep mode, the method further includes: continuing to monitor the heart rate information of each individual based on the radar module to obtain the heart rate change curve of each individual.

Specifically, after step 102, the auxiliary sleep control device of the air conditioner receives the heart rate information continuously monitored by the radar module for each individual, uses it as the heart rate information of the next moment, and updates the heart rate change curve.

When it is determined that all heart rate variation curves are consistent with the second state, the air conditioner is controlled to exit the sleep mode.

The second state is that the heart rate information is on an upward trend during the current monitoring period, and the increase is greater than or equal to the second preset threshold.

It should be noted that the second state refers to the heart rate information collected by the radar module in multiple consecutive working cycles under the current monitoring cycle. It increases with the increase of collection time, and the increase in heart rate information is greater than or equal to the second state. Preset threshold, the embodiment of the present application does not specifically limit the value of the second preset threshold.

Preferably, the second preset threshold is equal to the first preset threshold, which can be 10 times each, to avoid misjudgment caused by a disease outbreak corresponding to a sudden increase in the user's individual heart rate.

Specifically, the auxiliary sleep control device of the air conditioner analyzes the real-time updated heart rate change curves of all individuals. When it is determined that the change trends of the heart rate change curves of all individuals are consistent with the second state, it means that in the current indoor space, at least all If the individual users are all awake, the air conditioner will be controlled to exit the sleep mode and operate in the original working mode.

The embodiment of the present application monitors individual heart rate in real time based on the radar module, updates the heart rate change curve, and controls the air conditioner to exit the sleep mode when it is determined that the heart rate change curve conforms to the second state. It realizes wake-up status analysis based on individual heart rate changes, and adaptively switches the working mode of the air conditioner, so that all users can receive the fresh air volume in the original working mode after waking up, improving the control accuracy of room temperature and improving user experience. .

Decrease to 0.

It should be noted that a light-emitting array refers to a component that is fixedly arranged with at least one light-emitting element in a predetermined arrangement. For example, the light-emitting array can be a light strip located around the air outlet of the indoor unit to achieve light sensing changes in the sleep mode of the indoor unit and assist sleep.

Specifically, in step 102, when it is determined that the change trend of the individual's heart rate change curve is consistent with the first state, the air conditioner is controlled to switch from the current working mode to the sleep mode, and a first display voltage signal is also generated, and Send the first display voltage signal to the light emitting array.

The light-emitting array receives and responds to the first display voltage signal and gradually reduces its own brightness within a preset time period until it goes out (that is, the brightness is 0).

The embodiment of this application does not specifically limit the value of the preset duration.

For example, based on historical experience data, the preset duration is set to 10 minutes.

In the embodiment of the present application, while deciding to control the air conditioner to start the sleep mode, the first display voltage signal is used to control the light-emitting array to execute the light perception from bright to extinguished along with the process of gradually reducing the wind speed in the sleep mode. It is possible to switch the working mode of the air conditioner to the sleep mode, and at the same time, as the light perception fades, it assists the user to maintain a higher sleep quality and improves the user experience.

Based on any of the above embodiments, when it is determined that all the heart rate variation curves are consistent with the second state, it also includes: generating a second display voltage signal to control the brightness emitted by the light-emitting array to start from 0 for a preset time period. gradually increase.

Specifically, when it is determined that the changing trends of the heart rate change curves of all individuals are consistent with the second state, while controlling the air conditioner to switch from the sleep mode to the original working mode, a second display voltage signal is also generated, and the second display voltage signal is generated. The voltage signal is sent to the light emitting array.

The light-emitting array receives and responds to the second display voltage signal, and gradually increases its own brightness from off (ie, the brightness is 0) to bright within a preset time period.

In the embodiment of the present application, while deciding to control the air conditioner to exit the sleep mode, the second display voltage signal is used to control the light-emitting array to perform a light sensation from extinguishing to brightening along with the process of gradually increasing the wind speed in the wake-up mode. It realizes the switching of the air conditioner from sleep mode to original working mode, and at the same time, as the light perception gradually increases, it assists the user to maintain a higher level of wakefulness and improves the user experience.
