[0008] In one possible implementation, the signal strength condition is that the index position of the sensor corresponding to the maximum signal strength among the signals is within a set index range in the sensor array; before determining whether the preset signal strength condition is met based on the signals, the method further includes: Determine the signal strength of each signal, and compare the maximum signal strength among the signal strengths with a preset signal strength threshold; When the maximum signal strength is not less than the signal strength threshold, the noise strength of each signal is determined, and the maximum noise strength among the noise strengths is determined to be not greater than a preset noise strength threshold.

In one possible implementation, controlling the air pump to inflate the flexible airbag includes: Based on the pre-defined correspondence between body feature parameters and pressure thresholds, the target pressure threshold corresponding to the target body feature parameters of the tested object is determined. The air pump is controlled to inflate the flexible airbag, and the signals collected by the sensor array are acquired in real time.

[0019] With the rapid development of medical technology, pulse wave monitoring and analysis have become increasingly important health assessment methods. As technology advances, traditional manual pulse diagnosis is gradually being replaced by more precise and reliable instruments. In recent years, the emergence of array-type pulse wave sensors has provided new possibilities for pulse wave capture and analysis. However, existing devices cannot perform personalized signal acquisition for different populations, leading to inaccurate signal acquisition. Furthermore, the sensor's position and pressure require repeated manual adjustments for alignment, resulting in low signal acquisition efficiency and consequently poor measurement accuracy. Additionally, the need for personnel with relevant knowledge increases labor costs.

[0020] To address the aforementioned issues, this application provides an information acquisition method, apparatus, device, and storage medium. A standard line is provided on the surface of the flexible airbag, allowing the subject to be placed based on the standard line, improving the success rate of aligning the user's radial artery with the sensor. Furthermore, in response to the subject clicking the adjustment button, the height of the chamber can be adjusted in a direction perpendicular to the ground plane, allowing the airbag inside the chamber to fit more closely with the user's wrist, thereby improving signal acquisition quality. Additionally, the airbag can be rotated and adjusted according to the signal acquired by the sensor corresponding to the reference line, enabling the sensor array to accurately align with the radial artery, further improving signal acquisition quality. Moreover, the second and third sensor subarrays corresponding to the subject's cun (inch) and chi (scale) points can be determined based on the subject's body characteristic parameters, allowing for the acquisition of more complete pulse signals and improving measurement accuracy. Furthermore, this application automatically adjusts based on the signal acquired by the sensor array, eliminating the need for manual adjustment, saving manpower, and improving signal acquisition efficiency.

[0021] like Figure 1 The diagram shown is a schematic of a pulse information acquisition device provided in an embodiment of this application. The pulse information acquisition device includes an air pump 100, a flexible airbag 300 located in a silo 200, a sensor array 400 located on the surface of the flexible airbag 300, and a base 500.

[0022] In some embodiments, reference lines are provided on the surface of the flexible airbag 300, such as... Figure 2 As shown. This reference line can be marked with different colors or shown in other ways, and this application does not specifically limit it in this regard.

[0023] In some embodiments, the pulse information acquisition device further includes a controller 600, and a acquisition button 501 is included on the base 500. In response to the subject activating the acquisition button, the controller 600 controls the air pump 100 to inflate the flexible airbag 300. At this time, the sensor array 400 begins to acquire signals in real time and sends them to the controller 600. When the controller 600 determines that the pressure value of the signal acquired by the sensor array 400 reaches the target pressure threshold, it controls the air pump 100 to stop inflating the flexible airbag 300.

[0024] In some embodiments, the air pump 100 is located on the side of the base 500 and close to the silo 200 for inflating the flexible airbag 300 or discharging gas from the flexible airbag 300.

[0025] In some embodiments, the sensor array 400 may include multiple flexible sensors, forming a high-density piezoresistive sensor array on a polymer substrate using micro-nano fabrication technology. As an example, the sensor array may include hundreds of miniature sensors. Furthermore, each sensor in the sensor array 400 has an area of ​​only 1 mm² and uses a highly sensitive piezoresistive material. The preset sampling rate of the sensor array 400 is no less than 100 Hz, enabling it to precisely capture weak pressure fluctuations within the radial artery region using a pressure-sensitive area smaller than the width of the blood vessel; that is, it can convert extremely small pressure disturbances into significant electrical signals. When the pulse information acquisition device is activated, the controller 600 can first perform a self-test and calibration of the sensor array 400 to ensure the accuracy and stability of subsequent data acquisition. The high-density sensor layout enables precise capture of vascular pressure distribution within a limited space, providing high-quality raw data for subsequent waveform analysis.

[0026] To balance positioning stability and temporal resolution, this application employs a two-level sampling strategy. The first is a global low-sampling inspection: polling the entire sensor array's row and column coordinate space at a low frame rate to assess fit and pressure distribution in real time, serving as a positioning reference. The second is a local high-sampling: after determining the target areas corresponding to dimensions (inch, close, and scale), the controller sets a programmable sub-array window (region of interest, ROI) within these areas, performing rapid cyclic sampling only on this window, and outputting frame data (carrying timestamps, frame numbers, and ROI coordinates) alternately with double buffering. Because the scanning window converges from the "entire array" to a "several rows × several columns" ROI, the single-frame traversal time is significantly shortened, thus achieving higher temporal resolution without increasing hardware channels. The above sampling method is applicable to any grid density and array size.

[0027] In some embodiments, the pulse information acquisition device may further include a first motor drive device connected to the flexible airbag 300 for driving the flexible airbag 300 to rotate.

[0028] In some scenarios, after the flexible airbag 300 is fully inflated, the controller 600 acquires signals from the target sensor set corresponding to the reference line, collected by the sensor array 400. The target sensor set is the collection of sensors located near the reference line. Specifically, the sensors within a defined area containing the reference line can be considered the target sensor set. For example, if the defined area containing the reference line includes four rows of sensors, the position of the target sensor set 410 within the sensor array 400 would be as follows: Figure 3 As shown.

[0029] The controller 600 adaptively generates a local sampling window based on the amplitude and centroid position of the target sensor set. This window covers the region of interest (ROI) near the reference line and consistent with the maximum pulse response. The device then switches to high-speed looping of the ROI: it prioritizes sampling at high frequency within this window and continuously outputs the data; at the same time, it intersperses global inspection frames at a set ratio (e.g., "ROI frame: global frame = K:1") to achieve a parallel data stream of "local high frequency and global low frequency".

[0030] Furthermore, when the signal collected by the target sensor set 410 does not meet the preset signal strength conditions, the first motor drive device can be controlled to rotate the flexible airbag 300. The rotation direction includes clockwise rotation around an axis, or counterclockwise rotation around an axis, where the axis is a straight line perpendicular to the circular cross-section of the silo 200 and passing through the center of the circular cross-section. Figure 4 As shown.

[0031] The aforementioned rotation and height adjustments are used to maximize the consistency between the ROI location and the main axis of the blood vessel. When the adjusted target sensor set meets the conditions, the controller locks this location as the reference for subsequent local high-sampling; if subsequent displacement or fit changes occur, it automatically reverts to global inspection to recalibrate the ROI and then re-enters high-speed mode to ensure that high sampling always applies to the actual inch, guan, and chi coverage areas.

[0032] In some embodiments, the pulse information acquisition device may further include a second motor drive device 700, which is connected to a first end of the outer surface of the silo 200. The silo 200 is connected to the base 500 via a support frame 503, and the silo 200 is movably connected to the support frame 503, such as... Figure 5 As shown. When the signal collected by the target sensor set 410 does not meet the preset signal strength condition, the second motor drive device 700 can be controlled to adjust the height of the silo 200. Specifically, the controller 600 can control the second motor drive device 700 to move in a direction perpendicular to the reference plane, so that the first end of the silo 200 moves relative to the second end of the silo 200 in a direction perpendicular to the reference plane. Here, the reference plane refers to the plane on which the pulse information acquisition device is placed. Figure 6 As shown, the first end of the silo 200 can be moved upward and the second end can be moved downward by controlling the second motor drive device 700 to move upward perpendicular to the reference plane.

[0033] In some embodiments, the base 500 includes an adjustment button 502. In response to the object being tested activating the adjustment button 502, the controller 600 controls the second motor drive device 700 to move the first end of the silo 200 in a direction perpendicular to the reference plane. The silo is designed to move in a direction perpendicular to the reference plane, which can improve the measurement comfort of the object being tested and also improve the fit between the pulse measurement site and the flexible airbag, thereby improving signal quality. The activation operation of the object being tested can be a long press, double-click, single click, etc., and this application does not specifically limit this.

[0034] In some embodiments, when the signals collected by the adjusted target sensor set 410 meet the signal strength conditions, the controller 600 can determine the first sensor subarray from the target sensor set 410 based on the signal strength of each signal collected by the adjusted target sensor set 410. Furthermore, based on the target body characteristic parameters of the tested object, a second sensor subarray corresponding to the radial artery cun point position and a third sensor subarray corresponding to the radial artery ulnar point position can be determined; and the first signals of the first sensor subarray, the second signals collected by the second sensor subarray, and the third signals collected by the third sensor subarray can be analyzed to obtain the pulse information of the tested object.

[0035] In some embodiments, the pulse information acquisition device further includes a third motor drive device 800 and an image acquisition device 900. The image acquisition device 900 is fixed directly above the silo 200, or may be fixed above the silo 200, and is located at the same end of the silo 200 as the second motor drive device 700. The image acquisition device 900 is used to acquire image data containing the object being measured. The third motor drive device 800 is disposed between the silo 200 and the base 500, and is located at the center of the first and second ends of the silo 200. The third motor drive device 800 can move in a direction perpendicular to the base 500, such as... Figure 7 As shown. Furthermore, the support frame 503 can be configured as a telescopic structure, with the telescopic direction perpendicular to the base 500. Additionally, since the third motor drive unit 800 is connected to the silo 200, when the third motor drive unit 800 moves in a direction perpendicular to the base 500, it can drive the silo 200 to move in the same direction. In some scenarios, when the third motor drive unit 800 moves, the second motor drive unit 700 is controlled to move in the same direction.

[0036] In some embodiments, the image acquisition device 900 can acquire an image containing the object under test, and then analyze the image to determine whether the target position of the object under test is located at the center of the image. Further, based on the image analysis results, the third motor drive device 800 can be adjusted to ensure that the target position of the object under test is located at the center of the image. As an example, the image acquisition device 900 can acquire an image containing the object under test and then determine whether the heart region of the object under test is located at the center of the image, thereby controlling the third motor drive device 800 to move in a direction perpendicular to the base 500.

[0037] In some scenarios, when the heart of the subject is determined to be above the center of the image, the third motor drive unit 800 can be controlled to move in a direction perpendicular to and away from the base 500. In other scenarios, when the heart of the subject is determined to be below the center of the image, the third motor drive unit 800 can be controlled to move in a direction perpendicular to and close to the base 500.

[0038] In some embodiments, during the movement of the third motor drive device 800, the image acquisition device 900 can acquire images in real time and determine whether the heart position of the subject is located at the center of the image. When it is determined that the target position of the subject is located at the center of the image, the third motor drive device 800 is controlled to stop moving.

[0039] See Figure 8 The diagram shown is a flowchart of an information collection method provided in an embodiment of this application, which specifically includes the following steps: Step S801: In response to the object being tested aligning its pulse measurement site with the reference line and activating the acquisition button, the air pump is controlled to inflate the flexible airbag, and after inflation is completed, the signals collected by the target sensor set corresponding to the reference line in the sensor array are acquired.

[0040] After inflation to the target pressure threshold and stabilization, the controller first executes one or more global low-sampling inspection frames to calculate the pressure peak index and energy distribution near the reference line, forming a target sensor set to provide coordinate basis for entering local high-sampling. This process is independent of array specifications and can be completed according to the set row and column step size and time step size.

[0041] In some embodiments, the target pressure threshold corresponding to the target body feature parameters of the tested object can be determined based on the preset correspondence between body feature parameters and pressure thresholds. Furthermore, an air pump can be controlled to inflate the flexible airbag, and signals collected by the sensor array can be acquired in real time. When the pressure value of the signal collected by the sensor array reaches the target pressure threshold, the air pump is controlled to stop inflating the flexible airbag.

[0042] In some embodiments, to improve signal acquisition quality, the relative position of the reference line to the sensor array is as follows: Figure 3 As shown, the target sensor set corresponding to the reference line can be multiple sensors in a defined area near the reference line, such as... Figure 3 As shown.

[0043] Step S802: If it is determined that the preset signal strength condition is not met based on each signal, then target adjustment is performed until the acquired signals meet the signal strength condition after adjustment; wherein, target adjustment includes at least one of the following: rotation adjustment of the flexible airbag, and height adjustment of the silo.

[0044] When the signal strength condition is met, the controller immediately establishes the Region of Interest (ROI) (window size, shape, and sampling priority are all parameterizable) and switches the acquisition process to a high-sampling loop prioritizing the ROI. If the condition is not met, it remains in the global inspection and mechanical adjustment closed loop until it is met. During the switching process, the frame data is continuous and the timestamp monotonically increases, facilitating seamless stitching by the host computer.

[0045] In some embodiments, the signal strength condition is that the index position of the sensor corresponding to the maximum signal strength among all signals is within a set index range in the sensor array.

[0046] As an example, when the index range is set to [35,35] – [45,45], and the index position of the sensor corresponding to the maximum signal strength is [37,15], it can be determined that the index position of the sensor with the maximum signal strength is not within the set index range, and target adjustment is required.

[0047] In some scenarios, the rotation parameters of the flexible airbag can be determined based on various signals, and the first motor drive device can be controlled to adjust the rotation of the flexible airbag based on the rotation parameters. Specifically, the index position of the sensor corresponding to the maximum signal strength among the signal strengths is determined in the sensor array; based on the index position and the preset index position, the rotation direction and rotation angle of the flexible airbag are determined; wherein, the rotation direction includes: clockwise rotation or counterclockwise rotation around the axis, and the axis is a straight line perpendicular to the circular cross-section of the silo and passing through the center of the circular cross-section.

[0048] As an example, when the index range is set to [35,35] – [45,45], the index position of the sensor corresponding to the maximum signal strength is [37,15]. To ensure that the index position of the sensor corresponding to the maximum signal strength falls within the set index range, the flexible airbag needs to be adjusted counter-clockwise. Furthermore, the corresponding rotation angle can be determined based on the sensor specifications, the index position of the sensor corresponding to the maximum signal strength, the set index position, and the drive parameters of the first motor drive device.

[0049] In other scenarios, the second motor drive device can be controlled to move in a direction perpendicular to the reference plane in response to the operation of the adjustment button of the object being tested, so that the first end of the silo moves in a direction perpendicular to the reference plane relative to the second end of the silo; the reference plane refers to the plane on which the pulse information acquisition device is placed.

[0050] In some embodiments, after target adjustment, new signals can be collected based on the adjusted target sensor set, and it can be determined whether the preset signal strength condition is met based on the new signals. If the condition is met, step S803 is executed; if the condition is not met, the above target adjustment operation is repeated until each signal collected after adjustment meets the signal strength condition.

[0051] Step S803: Determine the first sensor subarray from the target sensor set based on the signal strength of each signal collected by the adjusted target sensor set.

[0052] In some embodiments, the target sensor with the largest signal strength can be determined from the target sensor set, and the sensors within the set area where the target sensor is located can be used as the first sensor subarray.

[0053] like Figure 9 As shown, once the target sensor is determined, the sensor within the set area can be used as the first sensor subarray. Here, the set area is a rectangular area. Of course, it can be set to other set sizes or other set shapes (such as circles). This application does not make specific limitations on this.

[0054] Step S804: Based on the target body feature parameters of the tested object, determine the second sensor subarray corresponding to the radial artery cun point position and the third sensor subarray corresponding to the radial artery ulnar point position.

[0055] Once the first sensor subarray (corresponding to the off position) is determined, the second and third sensor subarrays corresponding to the cun and chi positions are derived by combining the target body feature parameters. This allows for simultaneous local high-resolution sampling of the three subarrays. The controller employs a time-slice multiplexing or multi-buffered parallel strategy, alternately outputting three ROI frames ("cun / off / chi") and low-frequency global frames within the same bus bandwidth to achieve synchronous high-temporal-resolution acquisition of pulse waves from the three locations.

[0056] Specifically, the index position of the first sensor subarray within the sensor array can be used as the target position corresponding to the radial artery artery's Guan point position of the tested object. Based on the target body characteristic parameters of the tested object, a first distance between the Cun point and the Guan point position, and a second distance between the Chi point and the Guan point position are determined at the pulse measurement site. The target body characteristic parameters are the tested object's height or wrist circumference data. Based on the sensor specifications, the first distance, and the target position, the index position of the second sensor subarray within the sensor array is determined. Based on the specifications, the second distance, and the target position, the index position of the third sensor subarray within the sensor array is determined.

[0057] Specifically, the first distance or the second distance can be determined by the following formula:

[0058] in, h For the user's height, c It is a universal length coefficient that can be determined through statistical analysis of groups with different heights and wrist circumferences.

[0059] Furthermore, based on the first distance and the sensor specifications, the index position of the second sensor subarray within the sensor array can be determined. For example, if the first distance is 1.2 cm, the index position of the first sensor subarray is [38, 40]-[40, 42]. If the sensor area is 1 mm², and assuming the second sensor subarray includes the same number of sensors as the first, then the index position of the second sensor subarray can be determined as [26, 40]-[28, 42]. Similarly, the index position of the third sensor subarray can also be determined in the same way, and will not be elaborated further here.

[0060] Step S805: Analyze each first signal collected by the first sensor subarray, each second signal collected by the second sensor subarray, and each third signal collected by the third sensor subarray to obtain the pulse information of the object being measured.

[0061] In some embodiments, after the flexible airbag is inflated, the sensor array can be controlled to sample inspection frames at a first sampling frequency. Then, after determining the second and third sensor subarrays, the first, second, and third sensor subarrays are controlled to collect information at a second sampling frequency; wherein the second sampling frequency is greater than the first sampling frequency.

[0062] The higher temporal resolution resulting from local high sampling facilitates the accurate extraction of key features such as rising edge, peak / diplophonic wave, interbeat variation, and pulse transit time, while also enhancing resistance to motion and baseline drift. Global frames continuously provide steady-state monitoring of fit and background pressure. Once the two types of data are aligned on the time axis, they can be directly fed into filtering, denoising, and feature analysis modules to generate pulse information. Furthermore, the method places no restrictions on array size or ADC architecture (i.e., the structure and operating principle of the digital-to-analog converter), allowing for smooth migration to arrays and hardware platforms of different specifications.

[0063] In some embodiments, a data analysis module can be invoked to perform basic processing such as filtering and denoising on the first, second, and third signals, and then extract key features such as pulse rate, waveform, and amplitude to obtain the pulse information of the object being measured.

[0064] In some embodiments, before determining whether a preset signal strength condition is met based on each signal, the signal strength of each signal can be determined, and the maximum signal strength among the signal strengths of each signal can be compared with a preset signal strength threshold. When the maximum signal strength is not less than the signal strength threshold, the noise strength of each signal is determined, and the maximum noise strength among the noise strengths is determined to be not greater than a preset noise strength threshold.

[0065] This application introduces three-dimensional personalized self-positioning technology to achieve precise positioning of the radial artery at the wrist and high-resolution pulse signal acquisition. While maintaining the automatic recognition and fine-tuning functions in the X and Y directions, this application adds a flexible airbag structure that is adjustable in the Z direction, enabling the device to perform three-dimensional adaptive positioning according to the wrist shape and comfort needs of different users, thereby significantly improving the accuracy of pulse diagnosis and ease of operation.

[0066] Secondly, in terms of hardware structure, this application employs flexible sensors made of skin-friendly materials, forming a high-density piezoresistive sensor array on a polymer substrate using micro-nano fabrication technology. Because each sensor has an area of ​​only about 1 mm², and a highly sensitive piezoresistive material is used, even extremely small pressure disturbances can be converted into significant electrical signals. Upon device startup, the controller first performs a self-test and calibration of the micro-sensors to ensure the accuracy and stability of subsequent data acquisition. The high-density sensor layout enables precise capture of vascular pressure distribution within a limited space, providing high-quality raw data for subsequent waveform analysis.

[0067] Furthermore, to help the subject quickly align the radial artery with the sensor, this application adds a reference line, referred to as the "guan line," to the surface of the airbag for aligning with the "guan pulse" (radial styloid process). During use, after the subject roughly aligns their wrist with the guan line, the airbag begins to inflate, creating pressure on the wrist surface. The sensor array monitors the pressure distribution near the guan line in real time. When the device identifies a typical distribution characteristic of "low at both ends and high in the middle" (e.g., ...), the pressure is adjusted accordingly. Figure 10 (As shown in the image) When a series of high points appear, it can be confirmed that the radial artery and the control line are accurately aligned, and the midpoint of the series of high points is the "control point". If the device does not detect this distribution feature, or if the control point is too close to the edge of the sensor array, it can be corrected by fine-tuning or rotating the position of the airbag until the detection signal meets the requirements.

[0068] Furthermore, the airbag in this application is designed as a movable structure, allowing for vertical tilting within a set range. For example, it can move vertically within the range of 0° to -20°. The movement of this airbag structure can be controlled by a controller, allowing the subject to fine-tune the airbag's angle by clicking a button according to their physiological characteristics and comfort needs. This ensures a higher quality fit between the sensor array and the wrist surface in the Z-direction. This not only adapts to different wrist shapes but also allows for readjustment during measurement to address localized pressure anomalies or noise interference, resulting in optimal signal acquisition.

[0069] Furthermore, to ensure the accuracy of pulse measurement, this application calculates the theoretical positions of the "cun" and "chi" lines relative to the "guan" line based on the subject's basic data such as height and weight. After confirming the correct position of the "guan" line, the device combines the subject's input body characteristic parameters such as height, weight, and wrist circumference to perform algorithmic calculations on the distances between the "cun" and "chi" lines, confirming their positioning. After obtaining a stable signal, the device collects and records the pulse wave characteristics of the three key points ("cun," "guan," and "chi") and several surrounding high-pressure points. After filtering, noise reduction, and feature extraction, the final results can be displayed on the device screen in real time or broadcast to the user via a voice module. Simultaneously, the device supports wireless or wired uploads of more detailed waveform data to a cloud server for remote consultation or in-depth analysis. If the measurement needs to be performed on the other hand, the device automatically loads previously stored personalized parameters, helping the subject quickly reposition the "guan" line, "cun" line, and "chi" line, thus avoiding frequent recalibration.

[0070] The high-density sensor array in this application gives the invention significant advantages in spatial resolution and sensitivity. Due to the small size and close arrangement of individual sensors, sensors at different locations can simultaneously sense subtle pressure amplitude and phase changes in the blood vessels of the wrist, accurately identifying complex characteristics of the pulse such as its length, smoothness, roughness, and thinness. The controller's built-in digital filtering and signal amplification circuits can amplify the signal and extract key feature parameters, such as pulse rate, waveform amplitude, and rhythm, providing a complete quantitative basis for subsequent data analysis.

[0071] In summary, this application provides a complete self-localization information acquisition method. The adjustable design in the Z-direction simultaneously improves measurement comfort and signal quality, satisfying the "cun, guan, chi" three-point localization requirements for pulse diagnosis while effectively adapting to individual differences in different subjects. The high-density sensor array provides higher spatial resolution and sensitivity, enabling the device to capture various minute pulse fluctuations and complex pulse characteristics.

[0072] In some embodiments, the pulse information acquisition device may also include an arm support plate disposed on the outside of one end of the silo, for supporting the forearm of the subject when the subject places the wrist into the flexible airbag.

[0073] The following is an example illustrating the overall information collection process, which includes the following steps: 1. The subject places their wrist into the flexible airbag, ensuring the forearm rests securely on the arm support plate. After roughly aligning the wrist with the radial styloid process according to the "Guanmai" marking line, the user can manually adjust the angle of the flexible airbag's chamber in the Z direction according to their own needs. Once a comfortable position is achieved, click the "Start" button, and the device will begin the data collection process.

[0074] 2. The controller instructs the built-in air pump to start working, and the flexible airbag expands evenly, applying moderate pressure to the wrist. At this time, the flexible sensor array adheres tightly to the wrist surface, thus laying a stable foundation for subsequent accurate capture of pulse signals.

[0075] 3. The sensor array detects the wrist pressure distribution in real time. When a series of high-pressure points are detected in the artery marker area, the system confirms that the radial artery is aligned. If the signal is weak or the distribution does not match the set conditions, the controller controls the first motor drive device to fine-tune the rotation angle of the airbag until the signal strength meets the requirements and the distribution matches the set conditions. Then, the controller determines the first sensor subarray corresponding to the artery point based on the signal collected by the sensor array. Specifically, the flexible airbag can release some pressure and rotate slightly towards the side with a stronger signal, and then increase the pressure appropriately after rotation to make the flexible airbag fit the arm of the subject being tested more closely.

[0076] 4. Based on the body characteristic parameters of the tested object (height, weight, wrist circumference, etc.), the controller determines the theoretical positions of "cun" and "chi" and collects signals through the corresponding sensor subarrays (i.e., the second and third sensor subarrays). In some scenarios, if the signals collected by the sensor subarrays do not meet the requirements, adjustments are made by fine-tuning the silo or rotating the flexible airbag. If the three points of "guan," "cun," and "chi" are still not detected after a set number of adjustments, the tested object is prompted to readjust its wrist posture.

[0077] 5. The controller acquires the pulse signals collected by the first sensor subarray, the second sensor subarray, and the third sensor subarray, and calls the data analysis module to perform basic processing such as filtering and noise reduction, and then extracts key features such as pulse rate, waveform, and amplitude.

[0078] 6. After data extraction and analysis, the device will broadcast the measurement results to the subject through its built-in voice module, including the current pulse rate and waveform characteristics, allowing the subject to understand the relevant information in real time. Finally, the data transmission module will package the complete pulse data (including waveform characteristics of the three key points of cun, guan, and chi) and send it to an external device (such as a mobile phone, computer, or cloud platform) so that the subject can further analyze, store, and manage the relevant information on the terminal.

[0083] In one possible implementation, the signal strength condition is that the index position of the sensor corresponding to the maximum signal strength among the signals is within a set index range in the sensor array.

[0084] In one possible implementation, before determining whether a preset signal strength condition is met based on the signals, the first processing module 1101 is further configured to: Determine the signal strength of each signal, and compare the maximum signal strength among the signal strengths with a preset signal strength threshold; When the maximum signal strength is not less than the signal strength threshold, the noise strength of each signal is determined, and the maximum noise strength among the noise strengths is determined to be not greater than a preset noise strength threshold.

When the pressure value of the signal collected by the sensor array reaches the target pressure threshold, the air pump is controlled to stop inflating the flexible airbag.
