Example one
Modern medical research shows that a complete sleep cycle is divided into three different stages, namely a wake period, a light sleep period and a deep sleep period. A sleeper typically exhibits different physiological activity characteristics during different sleep stages. During the wake period, the breathing rate of the sleeper is usually unstable and is accompanied by relatively large body movements and limb movements, such as kicking, turning over, arm waving, etc., while during the light sleep period, the breathing rate of the sleeper tends to be stable, and the body movements and limb movements are mainly classified as trembling limbs or leg twitching. During deep sleep, the sleeper's breathing rate is further slowed down, at which time physical movements and limb movements rarely occur. The change rule of physiological parameters of a human in different sleep stages is specifically shown in the following table 1.
TABLE 1 physiological parameter variation law in different sleep stages
| Wake period | Period of light sleep | Deep sleep period |
| Respiration rate | Fastest speed | Is slower | Slowest speed |
| Respiratory stationarity | Large fluctuation and least stable | Is relatively stable | Is most stable and regular |
| Number of body movements | More times and long time | Less times of operation | Does not generate body movement basically |
According to the change rule of physiological parameters of a person in different sleep stages, the air conditioner sleep mode detection device provided by the invention detects the breathing action and the body action of the user during sleep, and transmits detection data to the air conditioner controller, and the air conditioner controller judges which sleep stage the person is in, so that the air conditioner controller judges whether the person enters the sleep mode, and adopts a proper control strategy after entering the sleep mode to adjust and control the parameters of the sleep mode of the air conditioner in real time.
Specifically, as shown in fig. 1, the air conditioner sleep mode detecting device includes a ceramic piezoelectric sensor for detecting a sleep state of a user, a piezoelectric signal processor for processing a signal of the ceramic piezoelectric sensor, and a wireless signal transmitting device for data transmission with the air conditioner controller. The core of the ceramic piezoelectric sensor is piezoelectric ceramic, and the electrical characteristics of the ceramic piezoelectric sensor are mainly shown to be sensitive to the change of weak pressure. When external mechanical force is applied, the internal positive charge center is relatively displaced to form polarization, so that a piezoelectric effect is generated, the interconversion from mechanical energy to electric energy can be realized, and the piezoelectric actuator can be used as a sensor and an actuator. The sensitive characteristic of the piezoelectric ceramic can capture extremely weak mechanical vibration and convert the mechanical vibration into an electric signal, even the air vibration generated by flapping the air by the winged piezoelectric ceramic can be captured, and the piezoelectric ceramic can not be separated from the production of household products such as acoustic transmitters, earphones, electronic music greeting cards and the like.
According to the invention, the ceramic piezoelectric sensor is arranged between the mattress and the bed sheet or on the upper surface of the mattress and the bed sheet, a pressure is generated on the ceramic piezoelectric sensor by the breathing action and the body action of a user in the sleeping process, and the piezoelectric sensor converts the breathing action, the body action and the tiny limb action into the micro-electric signal. As shown in fig. 2, the ceramic piezoelectric sensor converts respiratory motion and body motion into a micro-electrical signal, the piezoelectric signal processor amplifies the micro-electrical signal, and then wirelessly transmits a detection signal to the air conditioner controller through the wireless signal transmission device, and the air conditioner controller determines which sleep stage the user is in according to the received signal. The wireless signal transmission device can transmit signals in wireless transmission modes such as WIFI, Bluetooth and infrared, and is provided with a wireless signal sending module and a wireless signal receiving module.
The invention judges whether the user enters the sleep state or not by detecting the human body physiological signal of the user, avoids the defect that manual operation is not intelligent enough when the sleep mode is set manually, and also avoids the condition that the judgment modes such as sound, light and the like are easy to be interfered by the outside to generate misjudgment. The method has the advantages that the human body physiological signals of the user are detected, whether the user enters the sleep can be accurately judged, further, which stage the user is in the sleep can be accurately judged, whether the user is in deep sleep or shallow sleep can be accurately judged, air conditioner parameters can be adjusted according to different stages of the sleep, so that the requirements of the human body sleep on the environment are met to the maximum extent, the comfort is improved, and the sleep quality is improved.
When the air conditioner controller judges whether a person is in a sleep stage according to the received physiological signals of the user detected by the ceramic piezoelectric sensor and the change rule of various physiological parameters of the person in different sleep stages in the table 1, whether the person enters the sleep mode or not is judged, whether the person is in the sleep stage, namely the wake-up period, the shallow sleep period or the deep sleep period is further judged, and the parameters of the sleep mode of the air conditioner are adjusted and controlled in real time by adopting a proper control strategy after the person enters the sleep mode.
The specific sleep mode control method comprises temperature control, air deflector angle control, motor rotating speed control, display lamp panel control and the like.

the method comprises the following steps:
s1: the detection device detects a human physiological signal of a user and sends the human physiological signal to the air conditioner controller;
s2: the controller receives the human body physiological signal and judges the sleep state of the user according to the human body physiological signal;
s3: if the user does not enter the sleep state, controlling the air conditioner to operate at the set temperature of the current air conditioner;
s4: if the user enters the sleep state, judging the current working mode of the air conditioner;
s5: if the air conditioner is in a cooling or dehumidifying mode, controlling the set temperature of the air conditioner to gradually rise along with the increase of the sleep depth;
s6: and if the air conditioner is in a heating mode, controlling the set temperature of the air conditioner to gradually decrease along with the increase of the sleep depth.
The invention can adjust the temperature of the air conditioner according to different stages of sleep, so that the requirement of human sleep on the ambient temperature is met to the maximum extent, the comfort is improved, and the sleep quality is improved.
According to the invention, researches show that the set temperature of a general user is lower in a refrigerating state, the basic metabolism of the user is reduced along with the increase of the sleeping depth, the cold resistance is reduced, and the set temperature of the air conditioner is gradually increased to avoid cold. In the heating state, the set temperature of a general user is higher, and the set temperature of the air conditioner needs to be gradually reduced along with the increase of the sleep depth, so that the user does not feel dry and hot, and the user is not easy to wake up due to overheating, and the sleep quality is improved.
Specifically, the method comprises the following steps:
1) if the air conditioner is in the cooling or dehumidifying mode, that is, the step S5 further includes the following specific steps:
s51: the detection device detects the sleep state of the user at intervals of a time period;
s52, controlling the air conditioner to operate according to the current set temperature A when detecting that the user is in the wake period;
s53, when the first time detects that the user is in shallow sleep, the set temperature of the air conditioner is updated to the current set temperature A plus the 1 st preset adjusting value,
s54, when it is detected that the user is in shallow sleep, the set temperature of the air conditioner is updated to the current set temperature plus the 2 nd preset adjustment value;
s55, when the user is detected to be in deep sleep for the first time, the set temperature of the air conditioner is updated to the current set temperature plus the 3 rd preset adjusting value;
s56: when the user is continuously detected to be in deep sleep, the set temperature of the air conditioner is updated to be the current set temperature plus a 4 th preset adjusting value.
More preferably, when cooling or dehumidifying, the maximum operating temperature of the air conditioner is set in the sleep mode so as not to affect the comfort of the user, for example, all the operating temperatures of the air conditioner are set to be not more than 29 ℃.
The preset adjustment value for adjusting the temperature of the air conditioner in the sleep mode may be a suitable temperature range for increasing or decreasing the set temperature of the air conditioner, and the range of the preset adjustment values 1, 2, 3, and 4 is, for example: 0.5-2 ℃, preferably 1.5 ℃, 1 ℃ and 0.5 ℃, for example, the 1 st preset adjustment value can be 1 ℃, the 2 nd and 4 th preset adjustment values can be 0.5 ℃, the 3 rd preset adjustment value can be 1.5 ℃, and the adjustment is more accurate when the adjustment range is small, which is more beneficial to the comfort of users.
The time period may preferably be half an hour, 1 hour, 2 hours or the like.
For example: during the sleep mode operation in the refrigeration state, the air conditioner sets the operation temperature to be 27 ℃ before entering the sleep mode, the sleep mode detection device detects that the user is in the wake period after 1 hour, and the controller controls the air conditioner to set the temperature to be still 27 ℃; running for 1 hour again, and if the user is detected to be in a shallow sleep period, controlling the set temperature to rise by 1 ℃ to be 28 ℃; and running for 1 hour again, if the user is detected to be in a deep sleep period, controlling the set temperature to rise by 1 ℃ to 29 ℃, wherein the temperature is the highest temperature, and the set temperature is not increased for the comfort of the user.
For another example: during refrigeration or dehumidification, the operation temperature of the air conditioner before the user sleeps is set to be A, and after the air conditioner detects that the user enters a sleep state, the air conditioner executes the following logic: after entering the sleep mode, the sleep state of the user is detected every 1 hour. When detecting that the user is in the wake period, the air conditioner still executes according to the operation temperature A; when the first time that the user is in the light sleep is detected, the air conditioner operates according to the set temperature A +1 ℃, and when the user is continuously detected to be in the light sleep, the set temperature is increased by 0.5 ℃; when the user is detected to be in deep sleep for the first time, the air conditioner operates at the current air conditioner operation temperature of +1.5 ℃, and when the user is continuously detected to be in deep sleep, the set temperature is increased by 0.5 ℃.
2) If the air conditioner is in the heating mode, that is, the step S6 further includes the following specific steps:
s61, the detection device detects the sleep state of the user at intervals of a time period;
s62, when detecting that the user is in the wake period, controlling the air conditioner to execute according to the current set temperature B;
s63, when the user is detected to be in shallow sleep for the first time, the set temperature of the air conditioner is updated to be the current set temperature B minus the 1 st preset adjustment value;
s64, when the user is detected to be in shallow sleep continuously, the set temperature of the air conditioner is updated to the current set temperature minus the 2 nd preset adjustment value;
s65, when the user is detected to be in deep sleep for the first time, the set temperature of the air conditioner is updated to the current set temperature minus the 3 rd preset adjustment value;
s66: when the user is continuously detected to be in deep sleep, the set temperature of the air conditioner is updated to be the current set temperature minus the 4 th preset adjustment value.
More preferably, the lowest operating temperature of the air conditioner is set in the sleep mode during heating so as not to affect user comfort. For example, all the operating temperatures of the air conditioner are set to not lower than 20 ℃.
The time period may preferably be half an hour, 1 hour, 2 hours or the like.
For example: during heating, the operation temperature of the air conditioner before the user sleeps is set as B, and after the air conditioner detects that the user enters a sleep state, the air conditioner executes the following logic: after entering the sleep mode, the sleep state of the user is detected every 1 hour. When detecting that the user is in the wake period, the air conditioner still executes according to the operation temperature B; when the first time that the user is in the light sleep is detected, the air conditioner operates according to the set temperature B-1 ℃, and when the user is continuously detected to be in the light sleep, the set temperature is reduced by 0.5 ℃; when the user is detected to be in deep sleep for the first time, the air conditioner operates at the current air conditioner operating temperature of minus 1.5 ℃, and when the user is continuously detected to be in shallow sleep, the set temperature is reduced by 0.5 ℃.
(2) And (3) controlling the display lamp panel:
the sleep mode detection device monitors physiological signals of a user and judges whether the user enters a sleep state or not; if the user enters the sleep state, step S4 further includes the following steps of controlling the display light panel:
s41: the display lamp panel is extinguished;
s42: the detection device monitors whether a user presses a remote controller key or not;
s43: if the user presses the screen display key, the display lamp panel is extinguished after displaying the preset time normally;
s44: if the user operates the remote controller key within the preset time, the display lamp panel delays the preset time to extinguish after the last operation is finished;
s45: and when the sleep mode is cancelled, the display lamp panel state is executed according to the screen display state before entering the sleep mode.
After the monitoring user enters the sleep state, the brightness and the display time of the display lamp panel are further controlled, and the disturbance of lamplight to the sleep of the user is avoided.
The preset time may be 10s, 15s or other suitable time.
(3) Controlling the rotating speed of an indoor unit fan of the air conditioner:
the sleep mode detection device monitors physiological signals of a user and judges whether the user enters a sleep state. If the user enters the sleep state, after entering the sleep mode, step S5 or step S6 further includes the following steps of controlling the rotation speed of the indoor unit fan:
s101: if the user is in the wake-up period, controlling the rotating speed of the fan of the indoor unit not to be higher than a high wind level;
s102: if the user is in a shallow sleep period, controlling the rotating speed of the fan of the indoor unit not to be higher than a middle gear;
s103: and if the user is in the deep sleep period, the rotating speed of the fan of the indoor unit is not higher than the low wind level.
After monitoring that the user enters the sleep state, the rotating speed of the fan is further controlled, the phenomenon that the user feels too hot or too cold due to the air quantity is avoided, and the phenomenon that the sleep of the user is disturbed due to the rotating noise of the fan is also avoided.
(4) Controlling an indoor unit air deflector:
further, step S5 or step S6 further includes the following control steps:
s201: and as the sleeping depth is increased, the air deflector is controlled to rotate to a position where the wind direction deviates from the user.
Preferably, when the user is in the wake period, controlling the air conditioner air deflector to keep the set angle; when the user is detected to be in shallow sleep, controlling the air deflector of the air conditioner to rotate to a position where the wind direction deviates from the user; when the user is detected to be in deep sleep, the air deflector of the air conditioner is controlled to rotate to a position where the wind direction deviates from the user, until the air deflector rotates to an angle where the wind direction deviates the user most.
Generally, an air conditioner includes a vertically rotatable air guide plate, and also includes a horizontally rotatable air guide plate. Generally, the rotation angle of the air deflector rotating up and down has 5 positions from top to bottom, namely, the 1 st position, the 2 nd position, the 3 rd position, the 4 th position and the 5 th position.
In the case of cooling, generally, the 1 st and 2 nd lattices blowing upward are angles at which the wind direction deviates from the user, and the 3 rd lattice is most likely to blow straight to the user, causing discomfort to the user, so the 1 st and 2 nd lattices can be set to positions at which the wind direction deviates from the user. After entering a sleep mode, when a user is in an awakening period, the originally set air deflector angle is kept, if the originally set air deflector angle is set to be 3 rd/4 th/5 th, the air deflector angle is controlled to be continuously kept at 3 rd/4 th/5 th, if the originally set air deflector angle is set to be 1 st/2 nd, the air deflector angle is controlled to be continuously kept at 1 st/2 nd, when the user is detected to be in shallow sleep, the air conditioner air deflector is controlled to rotate to a position where the wind direction deviates from the user, at this time, three conditions exist, the originally set air deflector is rotated to be 2 nd when the originally set air deflector is set to be 3 rd/4 th/5 th, the originally set air deflector is rotated to be 1 st when the set air deflector angle is set to be the most wind direction, and the originally set air deflector angle is kept to be the 1 st because the 1 st grid is the most wind direction deviating from the user. When detecting that the user is in deep sleep, controlling the angle of the air deflector of the air conditioner to the 1 st grid, and keeping the air deflector still when the air deflector is in the 1 st grid.
Under the heating condition, the 4 th grid and the 5 th grid blowing downwards can be set as the angles of wind directions deviating from the user, and the air deflector gradually turns to the 4 th grid and the 5 th grid blowing downwards along with the increase of the sleeping depth, so that a good heating effect is also achieved.
Preferably, the user can set the position of the air deflector deviated from the user by himself, for example, the user can get on a bed or get off a table or get on or off a bed, and the proper position of the air deflector can be set as the position of the air deflector deviated from the user.
The position of blowing towards the wall can be set to be the position of deviating the wind direction from the user for the air deflector rotating left and right, and preferably, the user can set the position of deviating the wind direction from the user by himself.
After the monitoring user enters the sleep state, the angle of the air deflector is further increased, and overheating or overcooling of the user body caused by direct blowing of wind is avoided.
According to the invention, the ceramic piezoelectric sensor is used for detecting the sleep stage of the user in real time and adjusting and controlling the parameters of the sleep mode of the air conditioner in real time, including the display lamp panel, the temperature, the fan rotating speed, the wind guide angle and the like, so that the air conditioner is more intelligent compared with the traditional air conditioner which manually enters the sleep mode.
The invention detects the sleep state and the sleep stage of the user in real time through the ceramic piezoelectric sensor, and is more accurate compared with the control of controlling the air conditioner to enter the sleep mode through light detection such as lamplight and sound detection modes.
According to the control method of the sleep mode of the air conditioner, the control method of the corresponding display lamp panel, the temperature, the wind speed and the blowing angle is provided for each sleep stage of a user, and the user experience is more comfortable.
