However, the detection of the sensor has limitations, and the posture of the user may be in an abnormal state, and the correction product does not give an alarm, resulting in failure of the monitoring function of the correction product, and the existing posture correction product of the wearable type cannot determine whether the monitoring function is failed.

[0005] Furthermore, in the first sensing state, each of the flexible piezoresistive sensors is subjected to unilateral squeezing force from the skin on the back on the side closest to the human body.

[0006] Furthermore, in the second sensing state, each of the flexible piezoresistive sensors is clamped between the human back and the corrective backrest, thereby being subjected to bidirectional clamping pressure.

[0007] Furthermore, the corrective backrest is covered with a deformable fabric, one side of which forms the support surface of the corrective backrest, and several shaping units are located inside the support surface.

[0008] Furthermore, the shaping unit includes a servo motor and a support claw near the support surface. The servo motor can drive the support claw to move, and the support end of the support claw presses against the inner side of the support surface of the backrest.

[0010] Furthermore, a self-testing and debugging method for a human posture monitoring and correction system includes the following steps: L1: Pre-entering normal posture data of people of various body types into the correction backrest; L2: The user matches their own body characteristics, causing the correction backrest to actively form a corresponding correction shape; L3: The user wears a monitoring vest and leans against the correction backrest, causing the user's back to be corrected by the correction backrest.

The flexible piezoresistive sensor acquires sensing data B21 under the second sensing state. L7: The sensor compares whether sensing data B21 exceeds the normal fluctuation range of sensing data B20. If it does not exceed the range, it indicates that the monitoring function of the monitoring vest is normal. If it exceeds the range, it indicates that the monitoring function of the monitoring vest is malfunctioning, and the original sensing data A20 needs to be updated and re-recorded.

[0011] Beneficial Effects: The present invention discloses a human posture monitoring and correction system and its self-testing and debugging method. The sensor on the monitoring vest has two sensing states. When the sensor is in the first sensing state, the user wears the monitoring vest and engages in activities. After a period of time, the user leans against the correction backrest in a habitual posture that will not trigger an alarm, and switches the sensor to the second sensing state. If the user's posture does not trigger an alarm at this time, it indicates that the monitoring function of the monitoring vest is not malfunctioning. If the user's posture triggers an alarm at this time, it indicates that the monitoring function of the monitoring vest is malfunctioning, and data needs to be re-entered for debugging and correction.

[0016] The invention will now be further described with reference to the accompanying drawings.

[0017] As attached Figs. 1 to 4The aforementioned human posture monitoring and correction system and its self-testing and debugging method include a monitoring vest 1 and a correction backrest 2. The back array of the monitoring vest 1 has several flexible piezoresistive sensors 3, which include a first sensing state and a second sensing state. In the first sensing state, the monitoring vest 1 is worn and separated from the correction backrest 2, and the flexible piezoresistive sensors 3 obtain a set of sensing data (A). In the second sensing state, the monitoring vest 1 is worn and rests against the correction backrest 2, and the flexible piezoresistive sensors 3 obtain a set of sensing data (B).

[0018] The monitoring vest 1 is a tight-fitting structure when worn, allowing it to fit snugly against the user's body so that each flexible piezoresistive sensor 3 is in close contact with and presses against the back. The vest 1 is made of elastic material, ensuring it fits snugly against the user's body. The flexible piezoresistive sensors 3 determine the user's posture by detecting pressure values. Each flexible piezoresistive sensor 3 measures a pressure value within a normal range. If the pressure value measured by a particular sensor exceeds this range for a certain period (e.g., for 5 consecutive seconds), the user's posture is determined to be abnormal.

[0019] The monitoring vest 1 is also equipped with a control chip 5 and an alarm device 4. The alarm device 4 is a vibrator. When the flexible piezoresistive sensor 3 detects an abnormal posture of the user, it transmits the detection signal to the control chip 5. The control chip 5 then controls the vibrator to vibrate and issue an alarm to remind the user of their abnormal posture. The vibrator has different vibration modes corresponding to the type of abnormal posture of the user, so that the user knows how to adjust their posture back to normal.

[0020] The corrective backrest 2 contains several electrically driven shaping units 8. The coordinated action of these shaping units 8 can change the shape of the support surface of the corrective backrest 2. The corrective backrest 2 is covered with a deformable fabric 9, one side of which forms the support surface of the corrective backrest 2. The shaping units 8 are all located inside the support surface. Each shaping unit 8 includes a servo motor 10 and a support claw 11 near the support surface. The servo motor 10 can drive the support claw 11 to move, with the support end of the support claw 11 pressing against the inner side of the support surface of the corrective backrest 2. Driven by the servo motor 10, the support claw 11 can actively change the shape of the support surface of the corrective backrest 2, or it can be adjusted to a passive mode, allowing the support claw 11 to adapt to the shape of the human back. The fabric 9 and the back cover 6 are combined to form a box-shaped structure. The shaping units 8 are located inside the box-shaped structure. A control unit 7 is also installed inside the box-shaped structure. The control unit 7 can control the movement of the support claw 11 and can wirelessly connect with the control chip 5.

[0021] However, in practical work, due to the shape and characteristics of the human back contour, even if the monitoring vest 1 is made of elastic material, it cannot completely conform to the human back. Therefore, the detection accuracy of the flexible piezoresistive sensor 3 has certain limitations. Even if the pressure values ​​measured by each flexible piezoresistive sensor 3 are within the normal range, the user's posture may still be abnormal. Therefore, there may be situations where the user's posture is abnormal but the vibrator does not issue a vibration alarm. In this case, the monitoring vest 1 cannot detect whether its own monitoring function has failed, which may cause the user to remain in an abnormal posture without realizing it. The setting of the corrective backrest 2 and the provision of two sensing states for the flexible piezoresistive sensor 3 are optimizations made to address the detection limitations of the flexible piezoresistive sensor 3.

[0022] In the first sensing state, the flexible piezoresistive sensor 3 is subjected to unilateral pressure from the skin on the side closest to the human body. In the second sensing state, the flexible piezoresistive sensor 3 is sandwiched between the human back and the corrective backrest 2, thus experiencing bidirectional pressure. In the first sensing state, the flexible piezoresistive sensor 3 experiences pressure from the skin on the back due to the elastic force of the monitoring vest 1. The flexible piezoresistive sensor 3 cannot guarantee complete contact with the skin, resulting in lower measurement accuracy and lower reliability of the A-group sensing data, making it prone to failure. In the second sensing state, because the flexible piezoresistive sensor 3 is sandwiched between the human back and the corrective backrest 2, the contact between the flexible piezoresistive sensor 3 and the skin is higher, leading to higher reliability of the B-group sensing data. Therefore, the B-group sensing data can be used to verify whether the A-group sensing data has failed, thereby determining whether the monitoring function of the monitoring vest 1 has failed. The following two technical solutions can be used to determine and correct the failure of the monitoring function of the monitoring vest 1:

[0023] The first technical solution includes the following steps:

[0024] S1: The user who needs to correct his posture first puts on the monitoring vest 1 and the user's posture is corrected manually. The user maintains the corrected posture. After visually judging that the user's posture is normal and healthy, the flexible piezoresistive sensor 3 is adjusted to the first sensing state and several flexible piezoresistive sensors 3 acquire the sensing data A10 in the first sensing state.

[0025] S2: The user maintains the corrected posture and leans against the corrected backrest 2. The shaping unit 8 on the corrected backrest 2 is passively deformed until it adapts to the shape of the user's back. Then the flexible piezoresistive sensor 3 is adjusted to the second sensing state. Several flexible piezoresistive sensors 3 acquire sensing data B10 in the second sensing state.

[0026] S3: After the user removes the corrective backrest 2, the flexible piezoresistive sensor 3 is adjusted back to the first sensing state, and the user wears the monitoring vest 1 for a period of time to carry out normal daily activities. The flexible piezoresistive sensor 3 determines whether the user is in a normal posture based on the sensing data A10. That is, it determines whether the data monitored by the flexible piezoresistive sensor 3 exceeds the normal fluctuation range of the sensing data A10 during the user's activities. If it exceeds the range, it is determined that the posture is abnormal, and the alarm device 4 issues an alarm to prompt the user to adjust back to a normal posture.

[0027] S4: After the user wears the monitoring vest 1 for a period of time, in order to determine whether the monitoring function of the monitoring vest 1 has failed, the user is asked to maintain the posture that he / she is accustomed to during the activity and does not trigger the alarm, and lean against the correction backrest 2 again, and the flexible piezoresistive sensor 3 is adjusted to the second sensing state. The flexible piezoresistive sensor 3 obtains the sensing data B11 in the second sensing state.

[0028] S5: Compare whether the sensor data B11 exceeds the normal fluctuation range of the sensor data B10. If it does not exceed the range, it means that the user's habitual posture during the activity that does not trigger the alarm is a normal posture, thus indicating that the monitoring vest 1's monitoring function is normal. If it exceeds the range, it means that the user's habitual posture during the activity that does not trigger the alarm is actually an abnormal posture, thus indicating that the monitoring vest 1's monitoring function is malfunctioning. Steps S1 to S3 need to be repeated to update and re-record the original sensor data A10. After the user is active again for a period of time, steps S4 to S5 are repeated to re-determine whether the monitoring vest 1's monitoring function is malfunctioning, thereby correcting the monitoring function of the monitoring vest 1.

[0029] The second technical solution includes the following steps:

[0030] L1: Input the normal posture data of people of various body types into the correction backrest 2 in advance; after people of various body types wear the monitoring vest 1, they lean against the correction backrest 2 in a healthy posture. The shaping unit 8 on the correction backrest 2 passively adapts to the corresponding shape, and the shape data of each shaping unit 8 on the correction backrest 2 is recorded so that the correction backrest 2 can reproduce different correction shapes.

[0031] L2: When a user needs posture correction, the corrector backrest 2 retrieves the pre-recorded data based on the user's gender, height, weight, waist circumference and other physical characteristics, and the shaping unit 8 on the corrector backrest 2 actively adjusts to the corresponding corrective shape.

[0032] L3: After the user wears the monitoring vest 1, it is placed against the correction backrest 2, so that the user's back is corrected by the correction backrest 2, and the flexible piezoresistive sensor 3 is adjusted to the second sensing state. At this time, the flexible piezoresistive sensor 3 acquires the sensing data B20 in the second sensing state.

[0033] L4: The user leaves the corrected backrest 2 while maintaining the corrected posture, and adjusts the flexible piezoresistive sensor 3 to the first sensing state. At this time, the user obtains the sensing data A20 in the first sensing state through the flexible piezoresistive sensor 3.

[0034] L5: When a user wears the monitoring vest 1 and engages in normal daily activities for a period of time, the flexible piezoresistive sensor 3 determines whether the user is in a normal posture based on the sensing data A20. That is, it determines whether the data monitored by the flexible piezoresistive sensor 3 exceeds the normal fluctuation range of the sensing data A20 during the user's activities. If it exceeds the range, it is determined that the posture is abnormal, and the alarm device 4 issues an alarm to prompt the user to adjust back to a normal posture.

[0035] L6: After the user wears the monitoring vest 1 for a period of time, in order to determine whether the monitoring function of the monitoring vest 1 has failed, the user is asked to maintain the posture that he / she is accustomed to during the activity and does not trigger the alarm, and lean against the correction backrest 2 again, and the flexible piezoresistive sensor 3 is adjusted to the second sensing state. The flexible piezoresistive sensor 3 obtains the sensing data B21 in the second sensing state.

[0036] L7: Compare whether the sensor data B21 exceeds the normal fluctuation range of the sensor data B20. If it does not exceed the range, it means that the user's habitual posture during the activity that does not trigger the alarm is a normal posture, thus indicating that the monitoring vest 1's monitoring function is normal. If it exceeds the range, it means that the user's habitual posture during the activity that does not trigger the alarm is actually an abnormal posture, thus indicating that the monitoring vest 1's monitoring function is malfunctioning. Steps L3 to L4 need to be repeated to update and re-record the original sensor data A20. After the user is active again for a period of time, steps L5 to L6 need to be repeated to re-determine whether the monitoring vest 1's monitoring function is malfunctioning, thereby correcting the monitoring function of the monitoring vest 1.

[0037] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
