As shown in FIG. 1 , in one embodiment, the smart seat proposed in the present application includes a seat 100 and a seat back 200 ;

The seat 100 is provided with a first pressure sensing device (not shown in the figure), and the seat back 200 is provided with a second pressure sensing device (not shown in the figure);

The smart seat also includes a display processing terminal 300 that is respectively connected to the first pressure sensing device and the second pressure sensing device. For example, the communication connection here can be implemented by a wired connection or a wireless connection. For example, this implementation In the example, a wireless communication connection is used;

The first pressure sensing device and the second pressure sensing device are used to sense the pressure in the contact area between the occupant and the seat when the seat is in use, and generate and output a pressure data signal to the display processing terminal 300,

The display processing terminal 300 is configured to perform sitting posture health monitoring based on the pressure data signal.

Specifically, in this embodiment, the sitting posture health monitoring is performed, including:

Visually display the pressure distribution information represented by the pressure data signal and the pressure value information at the preset point (as shown in FIG. 1 , it is a form of visualization of the pressure distribution performed by the display processing terminal 300 );

And based on the pressure distribution information represented by the pressure data signal and the pressure value information at the preset point, the sitting posture state is discriminated, and corresponding prompt information is output based on the discriminant result.

In order to facilitate the understanding of the technical solutions of the present application, here is a related introduction to the technical ideas proposed by the technical solutions of the present application:

The applicant has found through experimental research that, if the user sits with evenly distributed pressure on the chair surface, and the back of the chair is all leaning against the pressure evenly, the actual situation of the sitting posture at this time is generally that the table and chairs and the distances are standard and appropriate, and The sitting posture of the sitting person is correct, and the physical condition of the sitting person is that the pressure on the spine is small, the resistance of the whole body blood flow (in the sitting position) is small, and the distance between the eyes and the desktop reaches a healthy visual distance of 1 foot. On the contrary, the body may be prone, the spine is bent, the pressure value is large, the eye distance from the desktop is small, and the blood flow up and down relative to the body is slowed down, which is not good for health.

Specifically, for example, in practice, when the body of the occupant is slanted or slanted, the pressure sensing display of the sitting surface will show that the occupant sits upright on the seat or the partial or local pressure is very high; The inclination is more serious. At this time, the thighs and buttocks of the sitting person are often completely seated on the adjusted seat width and seat depth, and the back is far away from the seat back; these situations are bad sitting postures, which will affect health, such as the spine. , damage to the development of the sciatic nerve, pelvis and cervical spine, as well as damage to the eyesight.

Based on this, in this embodiment, by specifically configuring the display processing terminal, based on the pressure distribution information represented by the pressure data signal and the pressure value information at the preset point, the sitting posture state is discriminated, and corresponding prompts are output based on the discriminant result. information, including:

When, based on the pressure distribution information and the pressure value information at the preset point, it is calculated and determined that the difference between the pressure value of the local area of the seat and the average pressure of the seat as a whole is greater than the preset threshold, it is determined that the sitting posture of the occupant is skewed and the first output is correspondingly output. Prompt correction information, such as direct voice prompts for improper sitting posture and excessive pressure in specific areas, and give adjustment suggestions;

When, based on the pressure distribution information and the pressure value information at the preset point, it is calculated and determined that there is no pressure sensing at the seatback and there is pressure sensing in the entire seat area, it is determined that the occupant is leaning forward and the second prompt correction information is output accordingly. , where the second prompt correction information may include:

Prompt the user to adjust the height of the backrest and the depth of the seat surface, or adjust the distance between the seat and the table. For example, a voice prompts the user to adjust the height of the backrest, adjust the depth of the seat surface to a suitable standard, or the distance between the seat and the table edge It is far away, and the chair needs to be moved forward to a suitable distance (such as the distance between the abdomen and the edge of the table when the seated person is sitting). Based on the specific configuration, relevant health tips can also be displayed at the same time. The pressure is high, which is not conducive to the healthy development of the spine.

In addition, it is easy to understand that long-term sitting is also likely to cause related health problems. Therefore, in this embodiment, by performing specific configuration on the display processing terminal, the health monitoring of the sitting posture also includes:

Accumulated timing is performed according to the moment when the pressure data signal is generated and its continuous existence. When the accumulated timing exceeds the preset duration threshold (the specific value of the preset duration threshold can be configured based on the user's input), an early warning message is output. Users are prompted to engage in appropriate activities to avoid the health effects of prolonged sitting.

In some application scenarios, other extended applications can also be implemented based on pressure data. For example, it is necessary to judge whether the height of the seat surface is suitable for the height. For example, if the pressure at the contact point between the front end of the seat and the front and lower ends of the thighs is large, it means that the seat surface is not close to the ground. The distance is too high for the seated person, which will cause the blood flow in the front legs of the seated person to be unsmooth, and it is easy to make the front of the thigh and the calf and feet numb, which will cause damage for a long time. The pressure sensing data is visually displayed and relevant prompt information is given, so that the seated person can be aware of the situation and adjust the appropriate height of the seat surface. The softness and hardness of the surface, some main stress points (such as the position points corresponding to the ischium of the human body when sitting down) have a wide range of external extension and attenuation pressure, indicating that the cushioning layer of the seat surface is softer, and vice versa. The judgment of hardness indicates whether the seat of this hardness type is suitable for the user, etc.

In the technical solution of the present application, the seat and the seat back of the smart seat are provided with pressure sensing devices, based on the pressure sensing devices to sense the pressure in the contact area between the occupant and the seat, and based on the sensing device through the display processing terminal The pressure data signal is measured to monitor the health of sitting posture.
