Terms (such as those defined in generally used dictionaries) will be interpreted as having the same meanings as the contextual meanings in the relevant technical field and will not be interpreted as having idealized meanings or overly formal meanings unless clearly defined in the various embodiments of the present application.

In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

Usually, due to incorrect sleeping posture or problems with the bed material, the pressure value of a certain part is too high, which easily increases the probability of pressure sores. And because each bed material is fixed, most users cannot get a satisfactory comfort when sleeping.

Therefore, in order to solve the above problems, the present application proposes a posture adjustment method.

Please refer to Figure 1, which is a flowchart of a posture adjustment method proposed in an embodiment of the present application. Exemplarily, the posture adjustment method is applied to a posture adjustment device, for example, the posture adjustment device can be a posture adjustment air cushion, a posture adjustment sofa, etc.

In some embodiments, as shown in FIG. 1 , the posture adjustment method is applied to a posture adjustment device, the posture adjustment device includes a pressure sensor and a plurality of regional airbags, and the method includes:

S110, collecting point pressure parameters of each pressure matrix point where the user presses on the posture adjustment device.

Specifically, when the user presses on the posture adjustment device, each pressure matrix point in the device is pressed, so that each pressure matrix point generates a corresponding pressure parameter, wherein the pressure parameter includes a pressure value and a point position of the pressure matrix point.

In some embodiments of the posture adjustment method, as shown in FIG. 2 , the pressure sensor includes a longitudinal conductive layer 110 , a piezoresistive layer 120 , and a transverse conductive layer 130 .

The longitudinal conductive layer 110 includes a plurality of longitudinal conductive strips arranged in parallel and spaced apart; the transverse conductive layer 130 includes a plurality of transverse conductive strips arranged in parallel and spaced apart. The piezoresistive layer 120 is arranged between the longitudinal conductive layer 110 and the transverse conductive layer 130, so that the plurality of longitudinal conductive strips, the plurality of transverse conductive strips and the piezoresistive layer 120 form pressure matrix points. The longitudinal conductive layer 110 is connected to the transverse conductive layer 130 through the pressure matrix points to form a conductive loop.

Specifically, when the longitudinal conductive layer 110, the piezoresistive layer 120 and the transverse conductive layer 130 are sequentially overlapped, due to the different directions of the conductive strips in the longitudinal conductive layer 110 and the transverse conductive layer 130, a "conductive network" similar to a chessboard grid is formed. However, due to the fact that a layer of compression layer is set in the transverse conductive layer 130 and the longitudinal conductive layer 110, the overlapping part of the transverse conductive layer 130 and the longitudinal conductive layer 110 is not directly conductive, but the overlapping part of one of the conductive layers of the transverse conductive layer 130 and the longitudinal conductive layer 110 is connected to the overlapping part of the other conductive layer through the overlapping part of the compression layer to form a loop. Among them, the overlapping part of the compression layer, the overlapping part of the longitudinal conductive layer 110 and the overlapping part of the transverse conductive layer 130 overlap. Among them, the overlapping part of each compression layer is regarded as a point, that is, a matrix pressure point. Demonstratively, as shown in FIG. 3, the overlapping part is the part where two mutually perpendicular lines intersect and overlap.

The pressure sensor is arranged on an airbag cushion composed of several regional airbags. When the regional airbags are inflated or deflated, they drive the local pressure sensors at corresponding positions to move so as to adjust the pressure between the local pressure sensors and the user's body.

Specifically, the user presses on one side of the pressure sensor, and the airbag cushion is on the other side of the pressure sensor, that is, the pressure sensor is between the user and the airbag cushion. When the user presses on the pressure sensor, he also presses on the airbag cushion. When the airbag cushion is inflated or deflated, it will drive the pressure sensor to move, thereby driving the user's body to move. Since the airbag cushion is not inflated or deflated as a whole, but each regional airbag can be inflated or deflated independently, when the regional airbag is inflated or deflated, it will only drive the corresponding part of the pressure sensor to move, thereby driving the corresponding part of the user's body to move, so as to adjust the posture of part of the user's body.

Optionally, the shape of the surface of each regional airbag (i.e., the smallest unit) in contact with the pressure sensor may be the same as a closed figure composed of one or more matrix pressure points. For example, as shown in FIG3 , if the closed figure composed of the matrix pressure points is a rectangle, it is a rectangle of the first style in the figure, and the closed figure composed of the matrix pressure points is a rectangle of the first style. The shape of the surface of each regional airbag in contact with the pressure sensor may be the same as a closed figure composed of one matrix pressure point (i.e., the first style), or the same as a closed figure composed of three matrix pressure points (e.g., the third style), or the same as a closed figure composed of four matrix pressure points (e.g., the second style), etc., and there is no limitation here.

S210, determining the position of a body part of the user and an average pressure value corresponding to the position of the body part according to the pressure parameter of each point.

Specifically, since the entire posture adjustment device is relatively large, when the user presses on it each time, the pressed position is not a fixed position. As shown in FIG4 , only the pressed position is a darker color, and the greater the pressure, the darker the color, and the smaller the pressure, the lighter the color. Therefore, each time it is necessary to determine the current user's body part position and the average pressure value corresponding to the body part position based on the obtained pressure parameters, so as to facilitate subsequent calculations. Among them, the body part position is the position of the current body part in the posture adjustment device.

In some embodiments of the posture adjustment method, the pressure parameter includes a pressure value and a point position of a pressure matrix point, and determining the position of a body part of the user and an average pressure value corresponding to the body part position according to each point pressure parameter includes:

The pressure matrix points whose pressure values are not less than the screening threshold are screened out to determine the positions of the user's body parts.

Specifically, when the user presses on the posture adjustment device, the pressure value of the pressure matrix point corresponding to the part pressed by the user's body is not zero, which is used as a basis for determining the position of the user's body part. However, when the sensor is placed on a bed or sofa, there will be some wrinkles or additional pressure from accessories (such as sheets, cushions, etc.) on it, resulting in a pressure value greater than 0. The pressure matrix point with a pressure value greater than 0 may not be the user's body part position. Therefore, it is necessary to set a screening threshold to further accurately screen the user's body part position.

The average pressure value of all pressure matrix points whose pressure values are not less than the screening threshold is calculated as the average pressure value corresponding to the body part position.

Exemplarily, if the pressure values corresponding to all pressure matrix points whose pressure values are not less than the screening threshold are a, b, c and d respectively, then the average pressure value is Y=(a+b+c+d)/4, and the average pressure value corresponding to the body part position is Y.

S310, determining the target area airbag according to the position of the user's body part.

Specifically, since there are a large number of regional airbags in the entire posture adjustment device, in order to accurately adjust the user's posture according to the user's current posture, it is necessary to determine the target regional airbag to accurately adjust the user's posture, rather than adjusting each regional airbag. Among them, the target regional airbag is the regional airbag pressed by the user's body part.

Furthermore, the target area airbag is determined according to the pressure parameters of the pressure matrix point. Since the pressure matrix point and the target area airbag are not the same object, and the target area airbag is set on one side of the pressure sensor, it is also necessary to determine the target area airbag according to the pressure parameters of the pressure matrix point, that is, to find the target area airbag at the corresponding position according to the point position of the pressure matrix point. Among them, each area airbag corresponds to at least one pressure matrix point.

S410, adjusting the air pressure of the airbag in the target area according to the average pressure value to adjust the posture of the corresponding body part.

In some embodiments of the posture adjustment method, as shown in FIG5 , each regional airbag corresponds to a number of pressure matrix points; according to the average pressure value, the target regional airbag is adjusted to adjust the corresponding body part, including:

S411, obtaining a target pressure parameter of each pressure matrix point corresponding to each target area airbag.

S412, calculating the average airbag pressure of each target area airbag according to the target pressure parameter.

Specifically, first determine all area airbags pressed by the user, that is, determine each target area airbag. Since each target area airbag corresponds to at least one pressure matrix point, the pressure values of all pressure matrix points corresponding to each target area airbag can be obtained. The pressure values of all pressure matrix points corresponding to each target area airbag are averaged to obtain the average airbag pressure.

Exemplarily, if an airbag in a target area corresponds to three pressure matrix points, and the pressure values corresponding to the three pressure matrix points are m, n and q respectively, then the average airbag pressure is the average of m, n and q, that is, (m+n+q)/3.

S413, calculating an upper average pressure threshold and a lower average pressure threshold according to the average pressure value.

Specifically, due to the different physiques of each person, some people are heavy and some are light. Therefore, the average pressure value calculated in the end will also be different, and the corresponding average pressure threshold will be different. In order to make appropriate adjustments for each person in the end, the average pressure threshold adopted should also vary with the individual situation of the user. Among them, the average pressure threshold includes an upper average pressure threshold and a lower average pressure threshold.

Optionally, the average pressure threshold is calculated according to a preset multiple value of the average pressure value. For example, the preset upper multiple value of the upper average pressure threshold is 1.2, and the preset lower multiple value of the lower average pressure threshold is 0.8. When the average pressure value is 100, the upper average pressure threshold is 120, and the lower average pressure threshold is 80. Of course, the preset multiple value here can be adjusted arbitrarily according to different application scenarios, and there is no restriction here.

S414, when the average airbag pressure is greater than the upper average pressure threshold, the corresponding target area airbag is controlled to be exhausted.

S415, when the average airbag pressure is not greater than the lower average pressure threshold, the corresponding target area airbag is controlled to inflate.

Specifically, when the user presses the posture adjustment device, different postures will cause different pressure values at the pressure matrix points corresponding to each body part. Under normal circumstances (the most comfortable circumstances), the average pressure value of each target area airbag pressed by the user will not be too high. Therefore, when the average airbag pressure of a certain target area airbag is too large, it means that the pressure value brought to the user by the target area airbag here is too large, and the target area airbag needs to be exhausted to reduce the pressure. Conversely, when the average airbag pressure of a certain target area airbag is too small, it means that the pressure value brought to the user by the target area airbag here is too small, and the target area airbag needs to be inflated.

Exemplarily, if the target area airbags include airbag average pressure values of 90, 100, 120, and 130, and the average pressure value is 110, the upper average pressure threshold is 120, and the lower average pressure threshold is 100, then the target area airbag with a pressure value of 90 needs to be inflated, and the target area airbag with a pressure value of 130 needs to be deflated.

Optionally, the target area airbags whose average airbag pressure is greater than an upper average pressure threshold or not greater than a lower average pressure threshold may be inflated and deflated until the corresponding airbag pressure average reaches the average pressure value.

In some embodiments of the posture adjustment method, before determining the position of the user's body part and the average pressure value corresponding to the position of the body part according to each point pressure parameter, the method further includes:

The working mode of the posture adjustment device is determined based on the point pressure parameter of each pressure matrix point.

When the working mode of the posture adjustment device is the posture adjustment mode, the position of the user's body part and the average pressure value corresponding to the position of the body part are determined according to the pressure parameter of each point.

Specifically, the object pressed on the posture adjustment device is not necessarily a person, but may be an object, etc. Therefore, only when it is determined to meet the characteristics of a person, the posture adjustment working mode will be entered. After entering the posture adjustment mode, the above posture adjustment steps will be performed.

In some embodiments of the posture adjustment method, the pressure parameter includes the point position and pressure value of the pressure matrix point, and judging the state of the posture adjustment device based on the point pressure parameter of each pressure matrix point includes:

Based on the average of each airbag pressure, the user's breathing rate is calculated.

According to the breathing rate, determine whether the current state is posture adjustment mode.

Specifically, since the easiest and most intuitive distinguishing feature between people and objects is breathing, the user's breathing rate is calculated based on the average pressure of each airbag.

In some embodiments of the posture adjustment method, the breathing rate is calculated based on the average pressure of each air bag, including:

Calculate the standard deviation of the average airbag pressure of each area airbag within a preset time period.

Find the maximum standard deviation value among each standard deviation value.

The average pressure of each target airbag in the regional airbag corresponding to the maximum standard deviation value within a preset time period is obtained.

Specifically, when the user presses on the posture adjustment device to breathe, each part of the body fluctuates to a different degree, and the closer to the upper body (chest, stomach), the greater the degree of fluctuation. Therefore, it is most accurate to find the part of the body with the largest degree of fluctuation to calculate the breathing rate, and when the body fluctuates, the pressure value of the corresponding pressure matrix point pressed on the posture adjustment device changes accordingly, and the corresponding regional airbag pressure average value changes accordingly. Therefore, the corresponding user's breathing rate can be calculated according to the degree of change of the airbag pressure average value of each airbag. The standard deviation value is calculated for the airbag pressure average value of each airbag at continuous and different times. When the standard deviation value is larger, it means that the corresponding airbag has a larger degree of fluctuation, and it can better represent the user's breathing changes. Among them, the target airbag pressure average value refers to the airbag pressure average value of the regional airbag corresponding to the maximum standard deviation value within a preset time period.

Based on the average of each target airbag pressure, the user's breathing rate is calculated.

Specifically, the user's breathing rate is calculated according to the change in the average value of each target airbag pressure within a preset time period. The preset time period may range from 5 to 40 seconds, etc., and may also range from other values, which is not limited here and can be determined according to specific circumstances.

Further, a breathing curve is obtained according to each target airbag pressure average value, wherein the abscissa of the curve is time and the ordinate is the target airbag pressure average value. The breathing rate is calculated according to the spacing between each peak point in the breathing curve.

Exemplarily, if the 5th, 15th, and 26th data are peak points, then the interval between each breath is 10 and 11 data points, and the average of the interval time is 10.5, and if the interval between each data sample is 0.5s, then 10.5 data points is equivalent to one breath in 5.25 seconds, and the breathing rate is 5.25s/time.

Optionally, if a respiratory rate is detected first and then the breathing disappears when there is no obvious change in pressure, it is determined to be apnea, and an early warning signal is generated and recorded, or the early warning signal is transmitted to a monitoring room.

The embodiment of the present application proposes a posture adjustment method, which is applied to a posture adjustment device. The posture adjustment device includes a pressure sensor and several regional airbags. The method collects the point pressure parameters of each pressure matrix point pressed by the user on the posture adjustment device; determines the user's body part position and the average pressure value corresponding to the body part position according to each point pressure parameter; then determines the target area airbag according to the user's body part position; finally, adjusts the air pressure of the target area airbag according to the average pressure value to adjust the posture of the corresponding body part.
