Description

Technical Field

[0001] The utility model relates to the field of measurement technology, and in particular to a human body posture detection device and a system thereof, a wearable article and a dynamic detection device. Background Art

[0002] Traditional human posture detection relies on the professional's own visual and tactile detection, or combined with imaging methods. With the development of measurement equipment, the measurement of human posture has achieved higher measurement accuracy and better human safety, and dynamic measurement has become possible. Some imaging tools can perform image detection of human posture and can roughly track the morphological changes of the spine. However, these devices still need to expose the measured human body to an X-ray environment during detection, so their human safety is poor.

[0003] There are applications that use an inertial measurement unit (IMU) to measure the spatial coordinates, momentum, and path length changes of one or more positions of the human body, and monitor posture and motion based on the changes in spatial coordinates, momentum, and path length. An inertial measurement unit (IMU) is an electronic device that includes an accelerometer, a gyroscope, and a magnetometer sensor, which is used to measure motion and acceleration, and can be specifically applied to measure dynamic changes in human posture. Using an inertial measurement unit (IMU) sensor, combined with the known distance between the inertial measurement unit (IMU) sensors, the measured three-dimensional position and displacement data can be calculated. At present, inertial measurement unit IMU sensors have demonstrated their effective application in the measurement of spinal posture in patients with subacute and chronic low back pain and ankylosing spondylitis. For example, in a motion sensing system, two inertial measurement unit IMU sensors are installed at the thoracolumbar junction and the upper sacrum. To record whether the patient is sitting, standing, walking, or lying down at each time point during the measurement process. However, the inertial measurement unit IMU sensor has a complex structure and a large size, and can only be used in a relatively large area. Due to the large size of a single IMU sensor, a necessary gap must be maintained between IMU sensors. Therefore, this solution lacks measurement perception of the overall shape of the measured part and cannot measure the details of the human body posture. At the same time, when using multiple IMU sensors for motion measurement, measurement errors will accumulate, causing the measurement data to shift.

[0004] The above information is presented only as background information to help understand the present invention. No confirmation or other related meaning is given as to whether any of the above can be used as prior art applications related to the present invention. Utility Model Content

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0038] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly. In the present disclosure, "multiple" refers to two or more.

[0039] According to the embodiment of the present disclosure, Figure 1 As shown, a human posture detection device includes: a flexible circuit board 1 and an angular displacement measurement component 2 arranged on the flexible circuit board 1. For example, the angular displacement measurement component 2 is arranged at a measured position, and the measured position is, for example, a part of the human body. The angular displacement measurement component 2 is directly or indirectly attached to the measured position, which is conducive to more direct reception of the measurement signal. The flexible circuit board 1 is arranged on the side opposite to the measured position, and is directly or indirectly attached to the angular displacement measurement component 2, that is, the angular displacement measurement component 2 is located between the flexible circuit board 1 and the measured position, which is conducive to a more reasonable arrangement of the circuit module. The angular displacement measurement component 2 includes a plurality of angular displacement measurement units 20, each of which includes: an angular displacement measurement component 201 and an angular displacement connection component 202. The angular displacement measurement component 201 is configured to generate an angular displacement signal and includes a head end 201A and a tail end 201B relative to each other along its extension direction. The angular displacement measurement component 201 generates an angular displacement signal based on the position and shape of the head end 201A and the tail end 201B. The angular displacement connection member 202 is connected to one of the head end 201A and the tail end 201B. Figure 1 In the embodiment, the angular displacement connection component 202 is connected to the head end 201A. The angular displacement connection component 202 is also connected to the flexible circuit board 1 and is configured to receive the angular displacement signal and transmit the angular displacement signal to the flexible circuit board 1.

[0040] For example, in the angular displacement measuring assembly 2, the angular displacement measuring component 201 and the angular displacement connecting component 202 can be connected by welding, for example, by using a welding process such as brazing or ultrasonic welding. The angular displacement measuring component 201 and the angular displacement connecting component 202 can also be connected by bonding, for example, by using a medical grade silicone adhesive. The angular displacement measuring component 201 and the angular displacement connecting component 202 can also be plugged in, for example, a plug-in device is provided between the angular displacement measuring component 201 and the angular displacement connecting component 202. There is not only a physical connection but also an electrical connection between the angular displacement measuring component 201, the angular displacement connecting component 202 and the flexible circuit board 1 to achieve signal communication.

[0041] For example, a plurality of angular displacement measuring units 20 (eg Figure 1 The 41 angular displacement measuring units 20 shown are connected in series along the extension direction of the angular displacement measuring component 201. This connection mode is conducive to adjusting the size through the angular displacement measuring component 201 and the angular displacement connecting component 202, forming an angular displacement measuring unit array with different resolutions, and can realize the angular displacement measurement of the whole or local position with different precisions from millimeter level to decimeter level. The angular displacement measuring component 201 and the angular displacement connecting component 202 correspond to each other and are arranged alternately. One end of the angular displacement connecting component 202 in the angular displacement measuring unit 20 is connected to the angular displacement measuring component 201 in the same angular displacement measuring unit 20, and the other end is connected to the angular displacement measuring component 201 in the adjacent angular displacement measuring unit 20. The flexible circuit board 1 receives the measurement results of multiple angular displacement measuring components 2 and obtains the posture information of the measured position. The flexible circuit board 1 receives the measurement results of multiple angular displacement measuring components 2 in real time, and sends the posture information of the measured position to the remote server 6 in real time. The remote server 6 generates dynamic information of the posture of the measured position based on the posture information of the measured position received in real time.

[0042] For example, the flexible circuit board 1 and the angular displacement measurement component 2 include a shell, and the shell can be constructed of an elastomer, which is conducive to the human body posture detection device to better fit the physiological curvature of the measured position in a natural state. The material of the elastomer can be selected from a material containing silicon, and the elastomer can be configured as a medical-grade elastomer, which is conducive to being more friendly to the human body. The angular displacement measurement component 201 can be configured to use the same elastomer material as other components, and its measurement function is achieved by doping different layers with conductive or non-conductive materials in the elastomer material. The use of the same elastomer material is conducive to making the human body posture detection device have relatively consistent mechanical properties and operating temperature as a whole.

[0043] For example, the angular displacement measuring component 201 may include two flexible capacitors that run through the entire length of the angular displacement measuring component 201. The two flexible capacitors are located on both sides of the central axis of the angular displacement measuring component 201. When the angular displacement measuring component 201 is bent, the flexible capacitor on the inner side of the bending arc is compressed, while the flexible capacitor on the outer side of the bending arc is stretched, and a differential capacitance is generated between the two flexible capacitors. The differential capacitance is highly linearly related to the total angular displacement of the angular displacement measuring component 201, so that it will not be affected by some common noises, such as temperature fluctuations, pressure changes, etc. The angular displacement measuring component 201 can be measured using extremely low sampling power, and the signal is highly stable over time and will not drift. The differential capacitance generated by the two flexible capacitors is linearly related to the total angular displacement of the angular displacement measuring component 201, and the total angular displacement of the angular displacement measuring component 201 is integrated along the length direction of the flexible capacitors. Therefore, the differential capacitance measured by the angular displacement measuring component 201 is independent of the specific bending position and bending shape on the angular displacement measuring component 201. This characteristic eliminates the interference of irrelevant bends in the path of the angular displacement measuring component 201, and can more accurately measure the total angular displacement of the angular displacement measuring component 201.

[0044] For example, a pin header is provided between the angular displacement connection component 202 and the flexible circuit board 1 , and the pin header is configured to connect the circuit between the angular displacement connection component 202 and the flexible circuit board 1 to realize power supply and signal transmission of the human posture detection device.

[0045] According to the embodiment of the present disclosure, Figure 2a As shown, the human posture detection device includes a bonding layer 3 arranged between the angular displacement connection component 202 and the flexible circuit board 1, and the angular displacement connection component 202 is connected to the flexible circuit board 1 through the bonding layer 3. The bonding layer 3 can be a welding layer, for example, it is completed by a welding process such as brazing, ultrasonic welding, etc. The bonding layer 3 can also be an adhesive layer, for example, it is bonded by a medical grade silicone adhesive. The bonding layer 3 can also be a plug-in layer, for example, the bonding layer 3 is a plug-in layer formed by plugging two board-to-board connectors respectively arranged on the angular displacement connection component 202 and the flexible circuit board 1.

[0046] According to the embodiment of the present disclosure, Figure 2b As shown, the human posture detection device includes a flexible coating layer 4, which is arranged outside the angular displacement measurement component 2 and the flexible circuit board 1 to cover the angular displacement measurement component 2 and the flexible circuit board 1 as a whole or in part. The flexible coating layer 4 can cover the angular displacement measurement component 2 and the flexible circuit board 1 as a whole to obtain a more secure connection structure. The flexible coating layer 4 can also partially cover the angular displacement measurement component 2 and the flexible circuit board 1 to avoid some special parts while obtaining the connection structure. For example, the flexible coating layer 4 is a medical grade silicone coating layer.

[0047] According to the embodiment of the present disclosure, Figure 3 As shown, there are multiple angular displacement measurement assemblies 2, and multiple angular displacement measurement units 20 in each angular displacement measurement assembly 2 are connected in series to form a longitudinal column along the extension direction of the angular displacement measurement component 201, so that multiple angular displacement measurement assemblies 2 form multiple longitudinal columns. Multiple longitudinal columns are conducive to better coverage of the measured position and obtaining a wider range of measurement results. At the same time, since the distance between adjacent longitudinal columns is relatively close, the measurement results of adjacent longitudinal columns can be checked against each other, and the fault of the sensor can be identified according to the check result.

[0048] For example, the human body posture detection device further includes a plurality of transverse connecting members 5, each of which is connected between two angular displacement connecting members 202 in two adjacent longitudinal columns. The transverse connecting members 5 connect the angular displacement measuring units 20 into a mesh array. Figure 1 The long strip detection device shown, the mesh array is more conducive to detecting a larger detection surface, such as the detection of knees, elbows, large-area muscle postures, etc. By summarizing and processing multiple vertical column detection results, a more three-dimensional dynamic detection result can be obtained.

[0049] According to the embodiment of the present disclosure, Figure 4 As shown, multiple columns are arranged on the same flexible circuit board 1. Inside the same flexible circuit board 1, multiple multiplexers 1001, main control modules 1002, communication modules 1003 and power modules 1004 can be respectively arranged, and each column corresponds to a separate multiplexer 1001, main control module 1002, communication module 1003 and power module 1004, so as to measure different columns separately. Inside the same flexible circuit board 1, multiple multiplexers 1001, main control modules 1002, communication modules 1003 and power modules 1004 can be arranged one each, and multiple columns correspond to common multiplexers 1001, main control modules 1002, communication modules 1003 and power modules 1004, so as to simplify the circuit structure of the flexible circuit board 1 and better realize the integrated design.

[0050] For example, the angular displacement measuring component 201 includes a measuring module 2011 configured to generate an angular displacement signal, and a data interface 2012 located at one of the head end 201A and the tail end 201B of the angular displacement measuring component 201 and configured to send the angular displacement signal to the angular displacement connecting component 202. The data interface 2012 is connected to the angular displacement connecting component 202.

[0051] For example, the angular displacement connection component 202 is provided with a pin header at one end connected to the angular displacement measurement component 201. The pin header is connected to the data interface 2012 for power supply and signal transmission. For example, 4 pin headers are specifically provided, and the 4 pin headers are respectively connected to two capacitors. For example, 6 pin headers are specifically provided, and the 6 pin headers are respectively connected to the SDA, SCL, RST, INT, VCC, and GND pins of the data interface 2012.

[0052] According to the embodiment of the present disclosure, Figure 5 As shown, the flexible circuit board 1 includes a multiplexer 1001, the angular displacement measuring component 201 includes a measuring module 2011, and the angular displacement connecting component 202 includes a signal conversion module 2021. The signal conversion module 2021 receives the angular displacement signal measured by the measuring module 2011 and sends the angular displacement signal to the multiplexer 1001. The flexible circuit board 1 also includes a main control module 1002, a communication module 1003 and a power module 1004; the multiple angular displacement connecting components 202 include multiple signal conversion modules 2021, and the multiplexer 1001 is configured to receive multiple angular displacement signals sent by the multiple signal conversion modules 2021 and send the multiple angular displacement signals to the main control module 1002; the main control module 1002 is configured to generate real-time posture information, and send the real-time posture information to a remote server through the communication module 1003; the power module 1004 is configured to provide power to the flexible circuit board 1, the angular displacement measuring component 201 and the angular displacement connecting component 202.

[0053] For example, the multiplexer 1001 may be an i2c multiplexer, and specifically a TCA9548AI2CMultiplexer may be selected. The TCA9548AI2C Multiplexer may respond to the signal control of the main control chip and transmit the digital signals collected from each conversion module 2021 to the main control chip using the i2c communication protocol.

[0054] For example, the main control module 1002 may be an MCU or an FPGA, and devices with different performances may be selected according to the number of channels in the multiplexer 1001. For example, in the case of 8 channels or less, the nRF52840 chip may be specifically selected as the main control module 1002.

[0055] For example, the communication module 1003 may use Bluetooth or Wi-Fi, and the BMD-350-AR Bluetooth chip may be specifically used as the communication module 1003. The communication module 1003 may be integrated into the main control module 1002. For example, the aforementioned nRF52840 chip integrates the BLE low-power Bluetooth function. When the nRF52840 chip is specifically used, the communication module 1003 is integrated into the main control module 1002.

[0056] For example, the power module 1004 may be a 3.7V lithium-ion battery, and the specific model may be a PRT-13851 battery sold by Dejie Electronics. Since the power consumption required for the capacitor to generate differential capacitance is extremely low, the battery can simultaneously support the human posture detection device containing multiple columns to work continuously for a long time.

[0057] For example, the lengths of the multiple angular displacement measuring components 201 are not equal, and the head end 201A and the tail end 201B of each angular displacement measuring component 201 are set at the two ends of the natural physiological curvature position of the human body. At the measured position with high attention, a shorter length of the angular displacement measuring component 201 can be set to increase the density of the angular displacement measuring components 201, so as to obtain higher measurement accuracy at the measured position with high attention. At the measured position with low attention, a longer length of the angular displacement measuring component 201 can be set to reduce the density of the angular displacement measuring component 201, so as to save measurement devices and invest more resources in the position with high attention.

[0058] For example, the dimensions of the plurality of angular displacement measuring components 201 are the same, and the dimensions of the plurality of angular displacement connecting components 202 are the same. In this way, the standardization of measuring devices can be achieved, and the use of standardized devices is conducive to reducing the difficulty of production and manufacturing and reducing costs.

[0059] For example, the angular displacement measuring component 201 is a uniaxial sensor or a biaxial sensor for measuring the angular displacement along its length direction, and the biaxial sensor is configured to measure an orthogonal plane perpendicular to the length direction. In some measured positions, such as the bending of fingers, the angular displacement and posture of the human body in a single direction are mainly concerned. In this case, the angular displacement measuring component 201 can be a uniaxial sensor. In other measurement positions, such as the spine, while paying attention to the anterior-posterior curvature of the spine, the scoliosis of the spine is often also concerned. In this case, the angular displacement measuring component 201 can be a biaxial sensor. The biaxial sensor is configured to measure an orthogonal plane perpendicular to the length direction, and in the direction perpendicular to the spine, the curvature in two orthogonal directions, the anterior-posterior direction of the spine and the scoliosis direction of the spine, is measured simultaneously.

[0060] According to an embodiment of the present disclosure, a human posture dynamic detection system is also provided, comprising any human posture detection device in the aforementioned embodiments and a remote server 6, wherein the remote server receives the real-time posture information sent by the human posture detection device in real time, and generates a dynamic detection result based on the real-time posture information. For example, the remote server processes the real-time information into display information, and the display information is dynamically updated based on the real-time posture information sent by the human posture detection device to form a visualized dynamic detection result. For example, the remote server stores the real-time information, and further processes the stored information to obtain the required dynamic detection result.

[0061] According to an embodiment of the present disclosure, a wearable article is also provided, comprising any of the human posture detection devices in the aforementioned embodiments. For example, the wearable article is a device that can be worn or installed on the human body, such as a watch, jewelry, accessories, electronic equipment, etc., and the human posture detection device in any of the aforementioned embodiments is integrated on the device. For example, the wearable article is clothing that can be worn on the human body, such as underwear, pants, socks, etc., and the human posture detection device in any of the aforementioned embodiments is integrated on the clothing. For example, the human posture detection device in any of the aforementioned embodiments is integrated invisibly inside the wearable article to maintain the appearance of the wearable article. For example, the human posture detection device in any of the aforementioned embodiments is integrated visibly on the outside of the wearable article to facilitate integrated installation.

[0062] According to an embodiment of the present disclosure, a dynamic detection device for spinal morphology is also provided. The dynamic detection device for spinal morphology includes any one of the human posture detection devices in the aforementioned embodiments, and the human posture detection device is configured to detect the posture of the spine.

[0063] According to the embodiment of the present disclosure, Figure 6 As shown, in the human posture detection device, the lengths of the multiple angular displacement measuring units 20 along the extension direction of the angular displacement measuring component 201 are not equal, the angular displacement measuring units 20 arranged at the two end regions of the human posture detection device have a smaller length in the extension direction of the angular displacement measuring component 201, and the angular displacement measuring units 20 arranged at the middle region of the human posture detection device have a larger length in the extension direction of the angular displacement measuring component 201. This is conducive to forming a higher resolution at the two end regions of the human posture detection device, and further, in the dynamic detection of the spine morphology, more attention can be paid to the curvature of the cervical and lumbar vertebrae of the human body.

[0064] According to the embodiment of the present disclosure, Figure 7As shown, in the human posture detection device, the number of angular displacement measurement components 2 is 3, and the multiple middle longitudinal column angular displacement measurement units 20A and the two groups of side longitudinal column angular displacement measurement units 20B in each angular displacement measurement component 2 are respectively connected in series along the extension direction of the angular displacement measurement component 201 to form a longitudinal column, so that the multiple angular displacement measurement components 2 form 3 longitudinal columns. Among them, the lengths of the multiple middle longitudinal column angular displacement measurement units 20A along the extension direction of the angular displacement measurement component 201 are not equal, the middle longitudinal column angular displacement measurement units 20A arranged in the two end regions have a smaller length in the extension direction of the angular displacement measurement component 201, and the middle longitudinal column angular displacement measurement units 20A arranged in the middle region have a larger length in the extension direction of the angular displacement measurement component 201. The setting of the middle longitudinal column can correspond to the middle position of the human spine, which is conducive to forming a higher resolution in the two end regions of the human posture detection device, and further in the dynamic detection of the spine morphology, more attention can be paid to the curvature of the cervical and lumbar vertebrae of the human body. The lengths of the multiple angular displacement measuring units 20B arranged on both sides in the extension direction of the angular displacement measuring component 201 are equal. For example, the lengths of the angular displacement measuring units 20B arranged on both sides are greater than the angular displacement measuring units 20A arranged on the middle column in the two end regions, but less than the angular displacement measuring units 20A arranged on the middle column in the middle region. The arrangement of the two side columns can correspond to the positions on both sides of the spine, which is conducive to more uniform attention to the scoliosis of the human spine.

[0065] According to the embodiment of the present disclosure, Figure 8As shown, in the human posture detection device, the number of angular displacement measurement components 2 is 3, and the multiple middle longitudinal column angular displacement measurement units 20A and the two groups of side longitudinal column angular displacement measurement units 20B in each angular displacement measurement component 2 are respectively connected in series along the extension direction of the angular displacement measurement component 201 to form a longitudinal column, so that the multiple angular displacement measurement components 2 form 3 longitudinal columns. Among them, the lengths of the multiple middle longitudinal column angular displacement measurement units 20A in the extension direction of the angular displacement measurement component 201 are not equal, the middle longitudinal column angular displacement measurement units 20A arranged in the two end regions have a smaller length in the extension direction of the angular displacement measurement component 201, and the middle longitudinal column angular displacement measurement units 20A arranged in the middle region have a larger length in the extension direction of the angular displacement measurement component 201. The setting of the middle longitudinal column can correspond to the middle position of the human spine, which is conducive to forming a higher resolution in the two end regions of the human posture detection device, and further in the dynamic detection of the spine morphology, more attention can be paid to the curvature of the cervical and lumbar vertebrae of the human body. The lengths of the multiple angular displacement measuring units 20B arranged in the two sides in the extension direction of the angular displacement measuring component 201 are not equal. For example, the angular displacement measuring units 20B arranged in the two side longitudinal columns in the two end regions are longer in the extension direction of the angular displacement measuring component 201, and the angular displacement measuring units 20B arranged in the middle region are shorter in the extension direction of the angular displacement measuring component 201. The arrangement of the two side longitudinal columns can correspond to the positions on both sides of the spine, and this arrangement is more conducive to paying attention to the scoliosis in the middle region of the human spine.
