Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the related invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
As an embodiment of the present application, as shown in fig. 1, it is a schematic structural diagram of an intelligent temperature control adjustment system of a soft and hard adjustable mattress according to a first embodiment of the present application. As can be seen from fig. 1, the intelligent temperature control adjustment system for a soft and hard adjustable mattress provided by this embodiment includes:
a mattress body 101 comprising a hardness adjusting layer, a comfort contact layer and one or more functional layers; wherein the hardness adjusting layer adjusts the hardness of the mattress by adopting the principle of changing the air inflation quantity; the comfortable contact layer covers the soft and hard adjustable layer and is in contact with a human body, so that more comfortable contact touch feeling is provided; while the functional layer is embedded inside the comfort contact layer. The mattress body 101 is provided with a cooling layer on the upper surface of the comfortable contact layer, the cooling layer can generate cool touch feeling by directly contacting with human skin, and the cooling layer is made of materials such as bamboo fiber, hemp fiber, soybean fiber and modal fiber. A plurality of heating units are distributed in the functional layer inside the comfortable contact layer of the mattress body 101 and used for heating the mattress body. In this embodiment, when the heating unit is in a controllable operating state, heat can be generated to heat the mattress body, and the temperature of the heated mattress body can be controlled. Normally, the heat generating unit is in a non-operating state and does not generate heat.
And the temperature sensing module 102 is used for sensing the human body temperature and the environment temperature. In this embodiment, the temperature sensing module may be various types of temperature sensors for sensing the human body temperature and the ambient temperature. Specifically, a temperature sensor for sensing the temperature of the human body may be disposed at a position where the upper surface of the cooling layer of the mattress body is in contact with the human body, for sensing the temperature of the human body, such as a temperature sensitive capacitor; the bed body temperature sensor can also be arranged at other positions of the bed body to sense the human body temperature in a non-contact mode, such as an infrared temperature measuring sensor. The sensor for the ambient temperature can be arranged on the mattress body, and can also be arranged at other positions for sensing the temperature of the ambient environment.
The human body sleep state detection module 103 is used for detecting the sleep depth state of the human body, the distribution range of the human body on the mattress body, and the corresponding region positions of all parts of the human body on the mattress body. In this embodiment, after the human sleep state detection module 103 determines the distribution area of the human body on the mattress body, that is, the areas where different parts of the human body are located on the mattress body, when the temperature of the human body part in the target area needs to be changed, the temperature of the human body part can be changed by controlling the heating unit corresponding to the area on the mattress body. Meanwhile, the human body sleep state detection module 103 can also detect the sleep depth state of the human body, and different temperature control schemes are adopted to heat different parts of the human body according to different sleep depth states of the human body, so that the temperature sensed by each part of the human body is adaptive to the sleep state of the human body, and the sleep quality of the human body can be improved. Specifically, a plurality of pressure sensors may be disposed in the functional layer of the mattress body, and when a human body is in a sleeping state, the pressure applied to the load-bearing part of the mattress body is different from the pressure applied to the non-load-bearing part, so that the distribution range of the human body on the mattress body and the corresponding area positions of the respective parts of the human body on the mattress body can be determined. Meanwhile, when the human body is in a shallow sleep state, the motion of the human body on the mattress is more than that of the human body in a deep sleep state, the motion amplitude is larger, the motion of the human body on the mattress can cause the vibration of the mattress body, and the change of the pressure value of the human body on the mattress body is caused at the same time. Therefore, the sleep depth state of the human body can be judged according to the fluctuation range and the fluctuation frequency of the pressure value of the human body to the mattress body. Under the normal condition, when the fluctuation range and the fluctuation frequency of the pressure value of the mattress body by the human body are larger, the human body is in a shallow sleep state, and when the fluctuation range and the fluctuation frequency of the pressure value of the mattress body by the human body are smaller, the human body is in a deep sleep state. Because the pressure of the human body on the mattress can cause the change of the air pressure value in the soft and hard adjusting layer, the human body sleeping state detection module 103 can also adopt an air pressure sensor, the air pressure values of the soft and hard adjusting layer of the bearing part and the non-bearing part of the mattress body are different in size, so that the distribution range of the human body on the mattress body and the corresponding area positions of all parts of the human body on the mattress body can be judged, and the human body sleeping state is determined according to the fluctuation range and the fluctuation frequency of the air pressure value.
And the heating unit control module 104 is used for controlling the heating units in the corresponding regions to heat the mattress body in the regions where the heating units are located according to the sleeping depth state of the human body, the distribution range of the human body on the mattress body and the corresponding region positions of all parts of the human body on the mattress body and according to the detection of the human body temperature and the ambient temperature. After the sleeping state of the human body, the distribution range of the human body on the mattress body and the corresponding region positions of the human body parts on the mattress body are determined, the heating units in the regions of the mattress body corresponding to the human body parts are controlled by the heating unit control module 104 to heat the mattress body in the target region, so that the temperature of the mattress body in the target region reaches an ideal relative value according to the human body temperature and the ambient temperature and is matched with the sleeping state of a user.
Therefore, the intelligent temperature control adjusting system of the mattress with adjustable hardness, provided by the embodiment of the application, can effectively improve the sleep quality of a human body by detecting the sleep depth state of the human body and controlling the temperatures of different areas of the mattress according to the ambient temperature and the human body temperature.
As an optional embodiment of the present application, an air bag is disposed in the hardness adjusting layer of the mattress body, the hardness of the mattress body can be changed by changing the air pressure value in the air bag, and the air bag can be further configured with an air pressure adjusting unit for changing the air pressure value in the air bag. In this embodiment, the air pressure adjusting unit may be an inflating device, such as an inflator, through which the air bag can be inflated, so as to increase the hardness of the mattress body, and through which the air in the air bag can be exhausted, so as to decrease the hardness of the mattress body, and through inflating the air bag or exhausting the air in the air bag, the hardness of the mattress body can be adjusted.
As an optional embodiment of the present application, in the above embodiment, the air bag may include a plurality of independent chambers, the human sleep state detection module is connected to a plurality of air pressure sensors, the air pressure sensors are distributed in the independent chambers for collecting an air pressure value and an air pressure change value in the corresponding chambers, and the human sleep state detection module is configured to determine a distribution range of a human body on the mattress body and a corresponding region position of each part of the human body on the mattress body according to the air pressure value, and detect a sleep depth state of the human body according to the air pressure change value.

The smart phone may further be connected to a temperature sensor system of the home internet of things, from which the ambient temperature information is obtained.

Generally, when the difference between the temperature of one region of the human body and the ambient temperature is lower than the preset threshold corresponding to the region, the heating unit needs to be controlled to heat the mattress body corresponding to the region of the human body, and when the difference between the temperature of one region of the human body and the ambient temperature is not lower than the preset threshold corresponding to the region, the heating unit does not need to be controlled to heat the mattress body corresponding to the region of the human body. In this embodiment, the value range of the preset threshold may be 0.5 ℃ to 3 ℃.

As shown in fig. 3, the human sleep state detection module 103 includes: a sleep depth detection submodule 103A and a human body region detection submodule 103B. The sleep depth detection submodule 103A is connected with a pressure sensor of a functional layer of the mattress body to obtain a pressure value and a pressure change value; further, the sleep depth detection sub-module 103A counts a fluctuation range (i.e., a percentage of the average pressure change value with respect to the average pressure value) and a fluctuation frequency (i.e., an average number of fluctuations per minute) of the pressure value over a certain period of time (e.g., over 20 minutes) in the past, based on the pressure value and the pressure change value; when the fluctuation range is larger than a preset fluctuation range threshold value and the fluctuation frequency is larger than a preset fluctuation frequency threshold value, the current user is considered to be in a non-sleep state; when the fluctuation range is larger than the fluctuation range threshold value but the fluctuation frequency is lower than the fluctuation frequency threshold value, the current user is considered to be in a light sleep state; and when the fluctuation range is smaller than the fluctuation range threshold value and the fluctuation frequency is lower than the fluctuation frequency threshold value, determining that the current user is in the deep sleep state. The human body region detection submodule 103B is connected to the pressure sensors of the mattress body functional layer to obtain a pressure value of each pressure sensor, and determines a distribution range of a human body on the mattress body and a corresponding region position of each part of the human body on the mattress body based on the pressure value of each pressure sensor. Specifically, as shown in fig. 4, each pressure sensor on the mattress body corresponds to a certain mattress body region, the black circles are used to represent the pressure sensors, and the dotted square boxes are used to represent the corresponding mattress body region of each pressure sensor. The human body region detection submodule 103B judges whether the pressure value provided by each pressure sensor is greater than a preset pressure threshold value, if so, the mattress body region corresponding to the pressure sensor is determined to belong to a human body distribution range, so that which regions the human body distribution range on the whole mattress body includes can be determined at any moment, and the human body distribution range is a polygonal region formed by splicing rectangles of a plurality of mattress body regions; further, the human body region detection sub-module 103B calculates the degree of matching between the human body distribution range and a preset sleeping posture template, and divides the human body distribution range into region positions corresponding to various parts (such as the head, the back, the legs and the feet) of the human body according to the sleeping posture template having the maximum degree of matching with the current human body distribution range. For example, the mattress body region marked with oblique lines in fig. 4 is judged by the human body region detection submodule 103B to belong to the human body distribution range according to the pressure values; further, the human body region detection submodule 103B calls a sleeping posture template in the template library; the template library stores sleeping posture templates corresponding to various sleeping postures of human bodies, such as sleeping posture templates corresponding to various sleeping postures of stretching supine, curling supine, stretching lateral, curling lateral, stretching prone, curling prone and the like, wherein each sleeping posture template is represented in a form of a polygonal area formed by splicing a plurality of rectangular areas, and is shown in fig. 5; the human body region detection submodule 103B performs matching degree calculation on the determined human body distribution range and the sleeping posture template, for example, the human body distribution range may be divided into N × M grids according to the external rectangle thereof, and the sleeping posture template is divided into N × M grids according to the external rectangle thereof, as shown in fig. 6, and then determines whether the grid of the nth row and the mth column (N is less than or equal to N, M is less than or equal to M) of the N × M grids enters the human body distribution range and the polygonal region of the sleeping posture template at the same time, and if the condition is met, marks the grid as an overlapping grid; and after the judgment is carried out by traversing all the N x M grids, determining the proportion of the overlapped grids in the N x M grids, and if the proportion is higher than an overlapped threshold (for example, 85%), confirming that the human body distribution range is matched with the sleeping posture template. Furthermore, the human body region detection submodule 103B divides the polygon of the human body distribution range into the region positions corresponding to each part of the human body according to the human body region division manner preset by the sleeping posture template, for example, for the sleeping posture template of fig. 5, divides the sleeping posture template into a plurality of regions according to the external rectangles, and determines the human body part corresponding to each region; correspondingly, the human body distribution range matched with the template is divided into areas by the external rectangle according to the same division mode of the template, and each divided area corresponds to a corresponding human body part.
