[0002] Meditation, as an ancient and effective practice, has received widespread attention in the fields of psychology, neuroscience and health in recent years. The core of this practice is to deeply relax the body and mind and achieve inner harmony by improving self-awareness, emotions and mental state.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0031] It should be noted that when an element is described as being "fixed to" another element, it may be directly on the other element, or one or more elements may be located therebetween. When an element is described as being "connected to" another element, it may be directly connected to the other element, or one or more elements may be located therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0032] In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0033] The present application embodiment provides a seat 1000, see Figure 1 The seat 1000 may be arranged on any means of transportation, or the seat 1000 may be an office seat or a home seat.

[0034] The seat 1000 includes a pneumatic comfort system, a backrest 200 and a seat cushion 600. The backrest 200 is connected to the seat cushion 600. When an occupant sits on the seat cushion 600, the seat cushion 600 is used to bear the pressure of the occupant's buttocks, and the backrest 200 is used to bear the pressure of the occupant's back below the shoulders and the waist to the coccyx. Among them, the pneumatic comfort system includes a plurality of air bags 100, an air source 300, a controller 400, a pressure sensor 500 and a valve body (not shown). The plurality of air bags 100 are distributed on the backrest 200, and the plurality of air bags 100 are used to provide support and a comfortable massage experience for the occupant's back and waist. The air bag 100 is connected to the air source 300 through the valve body, and the controller 400 is connected to the valve body. The controller 400 is used to control the air source 300 to inflate the air bag 100 through the valve body, and the controller 400 is used to control the deflation of the air bag 100 through the valve body. The pressure sensor 500 is used to provide sensing data when the occupant acts on the seat 1000.

[0035] It is worth noting that the multiple air bags 100 are distributed on the backrest 200, and a part of the multiple air bags 100 corresponds to the waist of the occupant, so that when the air bag corresponding to the waist of the occupant is inflated / deflated, the occupant can be given assisted breathing training to enable the occupant to meditate and relax.

[0036] It is worth mentioning that Figure 1 The above is only an example of an arrangement of the plurality of air bags 100 . In actual applications, the plurality of air bags 100 may be arranged on the backrest 200 in other arrangements.

[0037] In addition, since each air bag 100 is connected to the air source 300 through the valve body, the inflation duration and / or inflation volume of each air bag 100 can be controlled by the air source 300 and the valve body respectively, so that when a specific air bag 100 suitable for the occupant's waist is matched according to the occupant, accurate assisted breathing training can be provided for the occupant.

[0038] The gas source 300 is used to provide gas to the airbag 300 to inflate it, so as to support or massage the occupant. The gas source 300 can be any device that can provide gas.

[0039] The pressure sensor 500 is used to provide sensing data when the occupant acts on the seat 1000. The pressure sensor 500 can be any device that can provide sensing data, and the specific structure of the pressure sensor 500 can adopt the existing technology.

[0040] It is worth noting that, in some embodiments, the pressure sensor 500 may also be connected to the controller 400, so that the controller 400 can obtain the sensing data of the occupant acting on the pressure sensor 500 to achieve the following assisted breathing training.

[0041] It is worth noting that the pressure sensor 500 is any device that can provide pressure data, and can be a pressure sensor, specifically a piezoresistive flexible fabric (pressure sensing pad), a piezoelectric film sensor, an optical fiber sensor or other array sensors.

[0042] For the valve body, the valve body can be any device that controls the on-off of the gas provided by the gas source, for example, a direct-acting solenoid valve or a pilot-operated solenoid valve.

[0043] The controller 400 is a control center, and is used to control the gas source 300 to inflate the air bag 100 through the valve body. The controller 400 is also used to control the deflation of the air bag 100 through the valve body. Figure 2 The hardware structure of the controller 400 includes: one or more processors 401 and a memory 402, Figure 2 A memory is taken as an example.

[0044] The processor 401 and the memory 402 may be connected via a bus or other means. In the embodiment of the present application, connection via a bus is taken as an example.

[0049] An embodiment of the present application provides a computer program product, which stores computer executable instructions. The computer executable instructions are used by a vehicle to execute the method of assisted breathing training in any of the following method embodiments.

[0051] The system embodiment described above is merely illustrative, wherein the units described as separate components may or may not be physically separated, and the components shown as units may or may not be physical units, that is, they may be located in one place or distributed on multiple network units. Some or all of the modules may be selected according to actual needs to achieve the purpose of the solution of this embodiment.

[0052] Through the description of the above implementation methods, ordinary technicians in this field can clearly understand that each implementation method can be implemented by means of software plus a general hardware platform, and of course can also be implemented by hardware. Ordinary technicians in this field can understand that all or part of the processes in the following embodiment methods can be completed by instructing related hardware through a computer program, and the program can be stored in a computer-readable storage medium. When the program is executed, it can include the processes of the embodiments of the following methods. Among them, the storage medium can be a disk, an optical disk, a read-only memory (ROM) or a random access memory (RAM), etc.

[0053] This application embodiment provides a method for assisting breathing training. Figure 3 , the method comprises the following steps:

[0054] Step S10, acquiring sensing data of the occupant acting on the pressure sensor.

[0055] The pressure sensor is arranged on the backrest of the seat, and the pressure sensor corresponds to the back below the shoulders of the occupant, and the waist to the coccyx. When the occupant sits on the seat and leans on the backrest, and pressure is applied to the pressure sensor, the pressure sensor generates sensing data about the back below the shoulders of the occupant, and the waist to the coccyx. For example, the sensing data includes electrical signals of each sensing point on the pressure sensor (including but not limited to voltage, current, capacitance, resistance, etc.). For example, the sensing data includes the coordinates of each sensing point on the pressure sensor. For example, the sensing data includes the coordinates of the acquired electrical signals.

[0056] It is worth noting that when the pressure sensor is also provided on the seat cushion of the seat, the pressure sensor corresponds to the buttocks of the occupant. When the occupant sits on the seat cushion and pressure is applied to the pressure sensor, the pressure sensor generates sensing data about the buttocks of the occupant.

[0057] Since different passengers have different skeletons, heights and weights, the pressures they apply to each sensing point of the pressure sensor are different, and the sensing data generated by the pressure sensor is different. The waist curves of different passengers can be distinguished based on the different sensing data.

[0058] It is worth noting that, in some embodiments, before step S10, that is, before obtaining the sensing data of the occupant acting on the pressure sensor, the airbag is also controlled to be in a deflated state. Through this setting, when the occupant acts on the backrest, the interference of the force on the pressure sensor caused by the expansion of the airbag can be reduced, thereby ensuring the occupant's action on the pressure sensor and ensuring the accuracy of the sensing data obtained from the occupant's action on the pressure sensor.

[0059] Step S20: Process the sensing data to obtain pressure data.

[0060] The pressure data is formed by converting the sensing data.

[0061] When the passenger uses the seat and applies pressure to the pressure sensor, some sensing points on the pressure sensor will generate obvious electrical signals (such as voltage, current, capacitance, resistance, etc.), and the signals of the corresponding areas being compressed can be displayed on the host computer. The signals of these sensing points being compressed constitute the pressure data.

[0062] Since different passengers have different skeletons, heights and weights, the pressures they apply to each sensing point of the pressure sensor are different, so the sensing data generated by the pressure sensor are different, and the corresponding converted pressure data are different.

[0063] Step S30: estimating the lumbar curve of the occupant according to the pressure data.

[0064] The pressure data may be in various forms, for example, the pressure data may include a pressure distribution diagram.

[0065] When the occupant uses the seat, pressure is applied to the pressure sensor, and multiple sensing points of the pressure sensor generate sensing data, which are then converted into multiple pressure values ​​and coordinates corresponding to the sensing data generated by the multiple sensing points. After the multiple pressure values ​​are amplified and processed by analog-to-digital conversion, the pressure distribution map can be generated in the image generator.

[0066] It should be noted that the pressure distribution map is a two-dimensional map showing the pressure values ​​of each sensing point. Each pixel in the pressure distribution map corresponds to a pressure value of a sensing point. The pressure distribution map can be a color map or a grayscale map.

[0067] When the pressure distribution map is obtained, the outline and size of the pressure distribution map are then obtained.

[0068] Among them, in some embodiments, the contour of the pressure distribution diagram formed by the pressure data generated by the pressure sensor located on the backrest is the contour of the occupant's back below the shoulders and the waist to the coccyx. One way to obtain the contour is to extract the contour position corresponding to the pressure value greater than the preset pressure threshold based on the pressure values ​​and positions of multiple sensing points based on binarization; and use connectivity detection to segment and form it based on the contour position.

[0069] The step of estimating the lumbar curve of the occupant according to the pressure data in step S30 is specifically: determining the lumbar curve of the occupant according to the outline and size of the pressure distribution diagram.

[0070] Since the waist curves (including height and weight) of different passengers are different, after they apply force to the pressure sensor, the sensing data generated at multiple sensing points of the pressure sensor are different, so the contour and size of the pressure distribution diagram in the pressure data formed by processing are different. It can be understood that the heavier the weight of the passenger, the wider the contour of the pressure distribution diagram formed, and the larger its size; similarly, the taller the height of the passenger, the farther the contour of the pressure distribution diagram formed is from the seat cushion, so the waist curve (including height and weight) of the passenger can be determined according to the contour and size of the pressure distribution diagram.

[0071] It is worth noting that, in some embodiments, after executing step S20, that is, after processing the sensing data to obtain pressure data, step S30 is not immediately executed, but the authenticity of the obtained pressure data is checked. For details, please refer to Figure 4 Before step S30, that is, before the step of estimating the lumbar curve of the occupant according to the pressure data, the method further includes:

[0072] Step S21, obtaining the angle information between the backrest and the seat cushion of the seat.

[0073] The angle between the backrest and the seat cushion of a seat usually refers to the angle between the backrest and the seat cushion, usually expressed in degrees (°). This angle determines the degree of inclination of the seat, which in turn affects the sitting posture and comfort of the occupants.

[0074] In some embodiments, an angle sensor, such as a rotary encoder, an angle sensor, etc., is installed at the connection between the backrest and the seat cushion of the seat, so that the angle change between the backrest and the seat cushion can be measured in real time.

[0075] In some embodiments, the seat is equipped with a camera or other image acquisition device, which can use image processing technology (such as edge detection, contour extraction, etc.) to identify the contours of the backrest and seat cushion and calculate the angle information between them.

[0076] In some other embodiments, a feedback mechanism may be designed in the adjustment mechanism of the seat. When the backrest is tilted, the sensor or switch is triggered by the change of the mechanical structure, thereby indirectly obtaining the angle information between the backrest and the seat cushion of the seat.

[0077] Step S22, judging whether the occupant is in a normal posture when acting on the pressure sensor according to the angle information and the pressure data, if so, executing step S30, if not, executing step S23.

[0078] The normal posture means that the occupant sits upright, and the contact area and pressure distribution between various parts of the body and the seat meet the preset safety or comfort standards.

[0079] In some embodiments, the method of determining whether the occupant is in a normal posture when acting on the pressure sensor may be to input the angle information and pressure data into a preset algorithm model, the model may calculate the occupant's posture characteristics according to the angle information and pressure data, and then compare the calculated posture characteristics with a preset normal posture standard. If the preset normal posture standard is met, it is determined to be a normal posture, otherwise it is determined to be an abnormal posture.

[0080] Step S23, controlling to correct the posture of the occupant and executing step S10.

[0081] There are many ways to control the posture correction of the occupant, such as guiding the occupant to adjust the posture through sound or visual prompts (such as prompts on a display screen) to achieve the purpose of correcting to a normal posture. Alternatively, seat belts or other safety devices are used to ensure that the occupant maintains a normal posture.

[0082] Through the above steps S21, S22 and S23, when the occupant is in a normal posture, step S30 is further executed, that is, the step of estimating the lumbar curve of the occupant according to the pressure data is executed, thereby improving the accuracy of estimating the lumbar curve of the occupant according to the pressure data. When the occupant is in an abnormal posture, the posture of the occupant is controlled to be corrected, and the accuracy of the estimated lumbar curve of the occupant can also be guaranteed.

[0083] In addition, for example, the waist curve of the occupant is determined based on the contour and size of the pressure distribution map formed above, then refer to Figure 5 Since the back below the shoulders of the occupant (above the first lumbar vertebra) and the waist to the coccyx (from the first lumbar vertebra to the coccyx) have obvious characteristics, the position of the occupant's waist can be clearly determined according to the occupant's waist curve, and then at least one target airbag corresponding to the occupant's waist can be selected.

[0084] It is worth noting that, in some embodiments, see Figure 6 The step S30, i.e. the step of estimating the lumbar curve of the occupant according to the pressure data, comprises:

[0085] Step S301, dividing the waist pressure data corresponding to the waist of the occupant from the pressure data.

[0086] The waist pressure data corresponding to the waist of the occupant is divided from the pressure data and is a collection of pressure data corresponding to the waist position of the occupant. These data can reflect the force applied to the waist of the occupant on the seat. Figure 5 Since the back below the shoulders of the occupant (above the first lumbar vertebra) and the waist to the coccyx (from the first lumbar vertebra to the coccyx) have obvious characteristics, the pressure data formed by the occupant in different areas of the pressure sensor on the seat back also have obvious characteristics, so the lumbar pressure data corresponding to the occupant's waist can be divided out from the pressure data.

[0087] In some embodiments, see Figure 7 Step S301, i.e. the step of dividing the waist pressure data corresponding to the waist of the occupant from the pressure data, comprises:

[0088] Step S3011, along the height direction, obtain the pressure mean value at each height from the pressure data, and form a pressure mean value change curve.

[0089] See also Figure 8 , Figure 8 A pressure mean change curve data is illustrated, wherein the horizontal axis is the pressure value and the vertical axis corresponds to the height, that is, a height data in the height direction of the occupant.

[0090] The height direction is still perpendicular to the seat cushion direction, or in the plane where the pressure sensor in the seat back is located, the farther away from the seat cushion, the higher the height.

[0091] Step S3012, obtaining a minimum pressure value and two maximum pressure values ​​in the pressure mean value variation curve, wherein the minimum pressure value is located between the two maximum pressure values.

[0092] According to the shape of the human spine ( Figure 5 ) shows that the bulge of the seat back near the first lumbar vertebra is higher, and the bulge of the tail vertebra to the seat back is higher, resulting in Figure 8A high pressure point is generated at the first lumbar vertebra, a low pressure point is generated in the area indicated by the lumbar vertebra, and a high pressure point is generated at the coccyx. According to this principle / phenomenon, in the pressure mean change curve obtained by the pressure sensor in the seat backrest, two maximum pressure values ​​and one minimum pressure value are found in the local area from top to bottom or from bottom to top, and the minimum pressure value is between the two maximum pressure values, then the area between the two heights corresponding to the two maximum pressure values ​​can be divided into the waist pressure data corresponding to the waist, that is, the following step S3013 is executed.

[0093] Step S3013: dividing the pressure data corresponding to the area between the two maximum pressure values ​​into waist pressure data corresponding to the waist of the occupant.

[0094] Step S302: obtaining the waist curve of the occupant according to the waist pressure data.

[0095] After the waist pressure data corresponding to the waist of the occupant is acquired, the waist curve of the occupant may be obtained. The waist curve may be a waist contour formed by the waist pressure data corresponding to the waist.

[0096] Step S40, selecting at least one target airbag corresponding to the waist of the occupant according to the estimation result of the waist curve of the occupant, and determining the inflation / deflation time of the target airbag.

[0097] Since multiple airbags are distributed on the seat back, a part of the multiple airbags must correspond to the waist. Therefore, after the waist curve of the occupant is determined, at least one target airbag corresponding to the waist of the occupant can be selected.

[0098] In addition, due to the specificity of the waist curve of the passenger, when the passenger acts on the seat back, the pressure data formed in various areas on the pressure sensor have different pressure values. According to the different pressure values ​​of various areas on the pressure sensor, the inflation time of the target airbag corresponding to the waist of the passenger can be determined, and then the deflation time can be determined. The deflation time can be equal to the inflation time, or calculated according to the inflation time and a preset algorithm. For example, the deflation time is 0.8 to 1.2 times the inflation time.

[0099] Among them, the method for determining the inflation time of the target air bag corresponding to the waist of the occupant according to the pressure value may be to calculate the inflation time of the target air bag according to a preset inflation target, wherein the inflation target may be to make the pressure value of the waist equal to the pressure value of the back, specifically, to make the pressure value corresponding to the lumbar vertebra equal to the pressure value corresponding to the first lumbar vertebra, or to make the pressure value corresponding to the lumbar vertebra equal to the pressure value corresponding to the coccyx.

[0100] Step S50, controlling the valve body to inflate / deflate the target airbag according to the inflation / deflation time, so as to assist the occupant in breathing training.

[0101] When the valve body is controlled to inflate / deflate the target airbag, inflation / deflation can be performed directly according to the determined inflation / deflation time, thereby assisting the occupant in breathing training.

[0102] In some embodiments, the valve body may be controlled to inflate / deflate the target air bag in other ways. For details, see Fig. 9 Step S50, i.e., the step of controlling the valve body to inflate / deflate the target air bag according to the inflation / deflation time to assist the occupant in breathing training, comprises:

[0103] Step S501, obtaining the breathing method that the passenger wants to practice.

[0104] The breathing method that the occupant wants to practice can be input by the occupant, or can be a preset breathing method selected by the occupant.

[0105] Step S502, obtaining the inhalation duration, exhalation duration, and inhalation / exhalation conversion method corresponding to the breathing method, and controlling the valve body to inflate / deflate the target air bag in combination with the inflation / deflation duration to assist the occupant in breathing training.

[0106] When providing assisted breathing training to occupants, refer to Fig.10 By inflating the target air bag 100, the occupant can be guided to inhale (Inhale), and by deflating the target air bag 100, the occupant can be guided to exhale (Exhale).

[0107] Among them, there can be many ways of breathing, such as abdominal breathing, breath-following method (method of following breathing), one-to-two breathing exercise method, alternating breathing method, etc.

[0108] Since different breathing methods correspond to different inhalation durations, exhalation durations, and inhalation / exhalation conversion methods, the inflation / deflation duration matching the breathing method can be determined based on the breathing method to be practiced by the occupant in combination with the inflation / deflation duration, according to a preset algorithm, the inhalation duration, and the exhalation duration, and then the valve body is controlled to inflate / deflate the target air bag to assist the occupant in breathing training.

[0109] The inhalation / exhalation switching method refers to, for example, in abdominal breathing, inhalation and exhalation are performed alternately, and the inhalation time is equal to the exhalation time. For another example, in the one-to-two breathing exercise, the exhalation time is twice the inhalation time, and the inhalation / exhalation switching method is equivalent to inhaling once and exhaling twice.

[0110] It is worth noting that, in order to further improve the accuracy and comfort of the assisted breathing training for the occupant, before step S50, that is, before the step of controlling the valve body to inflate / deflate the target airbag according to the inflation / deflation time to assist the occupant in breathing training, the method further includes:

[0111] Step S41, controlling the valve body to inflate the target airbag according to the inflation / deflation time.

[0112] Step S42, determining whether the occupant is satisfied with the inflated target airbag, if so, executing step S50, if not, executing step S43.

[0113] The method of judging whether the occupant is satisfied with the inflated target airbag may be through inquiry and occupant's reply, or through active input by the occupant, or in other forms.

[0114] Step S43, moving the target airbag upward by a preset distance along the height direction of the occupant, and executing step S50.

[0115] The preset distance may be 10% of the air bag height.
