Wherein, the radar module is under appointed time interval, periodically gathers all individual's in the room rhythm of the heart information to with this rhythm of the heart information transmission to the supplementary sleep controlling means of air conditioner. The working period of the radar module is not particularly limited in the embodiments of the present invention.

While the heart rate of a person is changed in a sleeping state, the number of times is about 64 to 84 times in the first minute, and the number of times is only about 45 to 50 times in a minute when the person enters a deep sleep state.
The first state refers to that the heart rate information acquired by the radar module in a plurality of continuous working periods decreases progressively along with the increasing of the acquisition time in the current monitoring period, and the decreasing amplitude of the heart rate information is greater than or equal to a first preset threshold.
Illustratively, the first preset threshold may be 10 times to avoid erroneous judgment caused by a disease burst corresponding to sudden heart rate reduction of an individual user.
Specifically, in step 102, the sleep assisting control device of the air conditioner analyzes the heart rate variation curves of all individuals, and when it is determined that the variation trend of the heart rate variation curves of the individuals conforms to the first state, that is, when it is described that at least one individual user is in a sleep state in the current indoor space, the air conditioner is controlled to switch from the current working mode to the sleep mode for operation.

Wherein the target inflection point is determined based on the heart rate information at the current monitoring period.
It should be noted that the target inflection point is an inflection point determined by a section of curve corresponding to the current monitoring period in the heart rate variation curve conforming to the first state, so as to represent a critical value of the heart rate when the user enters the sleep state.
Specifically, in step 103, the sleep assisting control device of the air conditioner extracts the current heart rate and the target inflection point in the current monitoring period from the heart rate variation curve conforming to the first state, and determines the sleep state of what degree the user is, so as to control the air conditioner to adaptively adjust the air speed of the indoor unit in the sleep mode.
The number of the heart rate variation curves conforming to the first state may be one or more, that is, one or more user individuals may be in a sleep state in the current indoor space.
Optionally, under the condition that the number of the heart rate variation curves conforming to the first state can be one, extracting the current heart rate and the target inflection point from the heart rate variation curve, and judging the degree of sleep state of the user individual, so as to adjust the wind speed of the indoor unit, and maintain the indoor temperature in a range suitable for the sleep state.
Optionally, under the condition that the number of the heart rate variation curves conforming to the first state can be multiple, extracting respective current heart rates from multiple different heart rate variation curves corresponding to multiple individual users, performing weighted average to serve as the overall current heart rate, selecting a maximum value from target inflection points of the multiple different heart rate variation curves, and using the overall current heart rate and the overall target inflection point to judge the average level of the horizontal states of the multiple individual users so as to adjust the wind speed of the indoor unit, so that the indoor temperature can be maintained in a range suitable for the sleep state.
According to the embodiment of the invention, the individual heart rate is monitored in real time based on the radar module, the heart rate change curve is obtained, and when the heart rate change curve is determined to accord with the first state, the air speed of the indoor unit is decided and adjusted according to the current heart rate and the target inflection point in the heart rate change curve when the air conditioner is switched to the sleep mode. The sleep state analysis is carried out according to the individual heart rate change condition, the air speed of the indoor unit is adaptively adjusted, the room temperature in the sleep mode is maintained in the range corresponding to the actual sleep state, the control precision of the room temperature is improved, and the user experience is improved.

It should be noted that the maximum heart rate value refers to the maximum value of all heart rate information in the heart rate variation curve in the current monitoring period.
Specifically, in step 103, the sleep assisting 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 start point and the end point of the threshold interval, and sets n points in the threshold interval for division, thereby obtaining n +1 heart rate subintervals.
Wherein n is a positive integer greater than or equal to 1. Each heart rate subinterval corresponds to a wind speed control gear.
And acquiring a target heart rate subinterval corresponding to the current heart rate to adjust the wind speed of the indoor unit to the target wind speed.
Wherein the target heart rate subinterval is one of all heart rate subintervals; 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 sleep assisting control device of the air conditioner takes a heart rate subinterval where the current heart rate is located as a target heart rate subinterval, takes a wind speed control gear corresponding to the heart rate subinterval as a target wind speed control gear, and controls wind speed generated when the rotating speed of the indoor unit is adjusted to the rotating speed indicated by the target wind speed control gear to be used as target wind speed to perform air supply in the sleep mode.
Exemplarily, a specific embodiment for adjusting the wind speed is given:
averagely dividing a threshold interval formed by a heart rate value D corresponding to the target inflection point and a maximum heart rate value T into 4 heart rate subintervals:
first heart rate subinterval
Figure BDA0003649605190000101
The corresponding wind speed control gear is the rotating speed of the indoor unit of 200 revolutions per minute.
Second heart rate subinterval
Figure BDA0003649605190000102
The corresponding wind speed control gear is 400 revolutions per minute of the rotating speed of the indoor unit.
Third heart rate subinterval
Figure BDA0003649605190000103
The corresponding wind speed control gear is the rotating speed of the indoor unit of 600 revolutions per minute.
Fourth rhythm of the heart subinterval
Figure BDA0003649605190000104
The corresponding wind speed control gear is 800 revolutions per minute of the rotating speed of the indoor unit.
If the current heart rate is in the first heart rate subinterval, namely the individual user is in a deep sleep state, the indoor unit is correspondingly controlled to supply air in a mode of rotating speed of 200 revolutions per minute.
It will be appreciated that the n points within the threshold interval may also be arranged at unequal intervals to demarcate a plurality of unequal heart rate sub-intervals.
According to the embodiment of the invention, the gradient division is carried out on the basis of the heart rate value corresponding to the target inflection point and the maximum heart rate value, and the target heart rate subinterval corresponding to the current heart rate is determined, so that the wind speed of the indoor unit is adjusted to the target wind speed corresponding to the magnitude, the quantitative adjustment of the wind speed according to the actual heart rate is realized, the control precision and efficiency of the wind speed are improved, the energy efficiency saving is also considered, and the user experience is optimized.

Specifically, the air conditioner sleep assisting control device calculates the current heart rate, the maximum heart rate value T and the target heart rate value D by using the corresponding mathematical model to obtain the target rotating speed of the indoor unit.
The embodiment of the invention does not specifically limit the mathematical model of the target rotating speed of the indoor unit.
Preferably, the mathematical model of the target rotating speed of the indoor unit is in direct proportional linear correlation, and the calculation formula is as follows:
V=600+(t-D)/(T-D)*(1200-600)
=600*[1+(t-D)/(T-D)]
and V is the target rotating speed of the indoor unit, and t is the current heart rate.
And the wind speed of the indoor unit is the target wind speed at the target rotating speed.
Specifically, the sleep-assisting control device of the air conditioner encapsulates the target rotating speed into a control instruction, so that the indoor unit receives and responds to the control instruction to supply air to the indoor unit at the target air speed.
According to the embodiment of the invention, based on the target heart rate value and the maximum heart rate value corresponding to the target inflection point, corresponding calculation is carried out by combining the current heart rate, and the target rotating speed of the indoor unit is obtained, so that the wind speed of the indoor unit is adjusted to the target wind speed under the action of the target rotating speed, the quantitative regulation of the wind speed according to the actual heart rate is realized, the control precision and efficiency of the wind speed are improved, the energy efficiency saving is also considered, and the user experience is optimized.
