[0039] An embodiment of the present application provides a method and system for health monitoring of fiber Bragg grating sensors, which can solve the problems in traditional applications that during the process of collecting physiological signals by fiber Bragg grating sensors, limited by the wearing method and external environmental factors, there are situations such as unstable signals and signal interference, affecting the accuracy and reliability of monitoring data.
[0040] Terms such as "first", "second", "third", "fourth", etc. (if any) in the specification, claims and above-mentioned drawings of the present application are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments described here can be implemented in an order different from that illustrated or described here. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these process, method, product or device. The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.
[0041] Please refer to Figure 1 , which is a flowchart of a method for health monitoring of fiber Bragg grating sensors provided by an embodiment of the present application, and specifically may include: S110 - S130.
[0042] S110, when a request for obtaining a pulsation signal using a fiber Bragg grating sensor is issued by a user, generate a sensor data verification prompt message, where the fiber Bragg grating sensor is along the central position in the thickness direction of the bracelet and has the same bending arc as the monitoring bracelet, and the sensor data verification prompt message includes a bilateral wrist alignment prompt message.
[0043] S120, collect bilateral pulsation signals based on the fiber Bragg grating sensor, and the monitoring bracelet is worn on one of the user's wrists.
[0044] S130, verify the sensor data according to the signal relationship of the bilateral pulsation signals to obtain the true pulsation signal of the user.
[0045] It is understandable that this method aims to solve the problem of pulse signal measurement errors caused by unstable bracelet wearing positions, uncomfortable wearing tightness, and external environmental interference in the prior art. The method is based on the structural design of arranging fiber Bragg grating sensors symmetrically along the center of the bracelet thickness direction and having the same natural bending curvature as the bracelet. By using the symmetry and similarity of pulse signals when the user's bilateral wrists are in contact, the effective verification of the data collected by the sensors is achieved. The core principle is to judge whether the wearing state meets the standard by monitoring the signal intensity, waveform similarity, and phase synchronization of bilateral pulse signals, and then eliminate abnormal signals caused by improper wearing or hand movements to ensure the acquisition of the user's true and accurate pulsation signals.
[0046] Exemplarily, when the user actively initiates a pulse detection request, the system will automatically generate a sensor data verification prompt message, which includes but is not limited to the prompt content of "align and press the bilateral wrists tightly", and will also prompt the user to keep still. The prompt message can be conveyed to the user in various ways such as the device display screen, mobile phone APP, LED indication, or vibration reminder, guiding the user to perform standardized wearing operations to ensure good preconditions for subsequent acquisition processes.
[0047] Exemplarily, the user aligns and presses the wrist on the side without wearing the bracelet tightly against the wrist on the side wearing the bracelet according to the prompt to form a stable bilateral contact state. Since the fiber Bragg grating sensors are arranged at the center position of the bracelet thickness direction and are consistent with the overall bending curvature of the bracelet in the natural state, when the wrists are in contact, the distances and contact areas between the sensors and the left and right wrists are symmetrically consistent. The sensors collect the direct pulsation signals of the wearing-side wrist and the pulsation signals transmitted through the contact on the other side in real time, and record the amplitude, waveform, and phase information of the signals on both sides to form complete original detection data.
[0048] Exemplarily, the system performs real-time analysis on the collected bilateral pulsation signals and completes data verification from the following three dimensions: First, detect whether the difference in bilateral signal intensities is within the preset threshold range. Only when the signal intensities on both sides are close does it indicate that the wearing is moderately tight, the bracelet curvature has been flattened, and the contact is good; Second, the system uses a signal correlation algorithm (such as Pearson correlation coefficient or DTW dynamic time warping) to compare the waveform similarity of both sides. Only when the preset similarity standard (such as more than 90%) is reached is it determined that the user's double-wrist contact and alignment are good; Third, judge the phase synchronization of the pulse signals on both sides through the phase analysis method to confirm whether there is a phase deviation caused by wearing offset or hand movement. If all the above three verification indicators meet the standards, the validity of the detection data this time can be confirmed.
[0049] Exemplarily, after the signal passes the verification, the system will eliminate the noise signals caused by loose wearing, misalignment or external interference, and only retain the qualified real pulse signal data as the output of the user's current health monitoring result, which can be uploaded to the remote medical platform or stored in the device database for subsequent health assessment, disease warning or doctor diagnosis.
[0050] Taking the home pulse monitoring of middle-aged and elderly users as an example, after the user wears the bracelet and fits the wrists of both hands according to the prompt, the device compares the bilateral signals in real time, confirms that the signal intensities are the same, prompts "normal wearing", and then outputs the real pulse signal and uploads it to the health management platform for doctor evaluation.
[0051] Taking the remote traditional Chinese medicine diagnosis and treatment scenario as an example, when the patient wears the bracelet at home and fits both hands, the medical staff can receive the pulsation waveform after data verification in real time, ensuring that the pulse information obtained by the doctor is true and reliable and reducing the risk of remote misdiagnosis.
[0052] In some examples, the fiber Bragg grating sensor is connected to a multi-channel fiber Bragg grating sensing array through an optical splitter. Each sensing unit corresponds to the pulse signal acquisition areas on the wearing side wrist and the contralateral wrist respectively, supporting the acquisition of at least two or more channels of synchronous signals and adapting to different wearing states and user wrist types. The sensor array is configured based on an SOA broadband light source and an adjustable Fabry-Perot (FP) filter, supporting high-precision tuning in the wavelength range of 1520 to 1570 nm to adapt to the minute pulse vibrations and temperature strain changes of the human body. The demodulation module may specifically include: a PSD photodetector for receiving the reflected signal and converting it into an electrical signal in real time to ensure complete signal sampling; a sawtooth wave voltage-driven piezoelectric ceramic tuner for achieving a high dynamic response by dynamically adjusting the light source wavelength to match the pulse changes on both wrists and meeting the pulse frequency range of 0.1 Hz to 10 kHz; a thermal expansion device integrated in the demodulation module for automatically compensating for the monitoring environmental temperature fluctuations, cooperating with the double-wrist fitting physical temperature control characteristics of this solution to further reduce the interference of temperature drift on signal measurement, and finally ensuring that the temperature compensation error of the user's true pulsation signal is within ±0.5°C. The user wears the bracelet and fits the two wrists together. The system synchronously acquires the pulse signals of both wrists through a multi-channel parallel demodulation fiber Bragg grating system. The demodulation module quickly demodulates the two-channel reflected signals to obtain real-time wavelength shift data and converts it into pulse signal amplitude and phase information. First, analyze the phase synchronization of the bilateral signals, and then compare the signal intensity consistency to generate a radian recovery confirmation message. After collecting the target pressure value, continue to monitor the single-wrist state of the user, and ensure stable subsequent acquisition conditions through pressure feedback and length adjustment. The real pulsation signals collected, after demodulation, have temperature compensation and dynamic response optimization characteristics, ensuring highly stable and reliable data. Thus, it supports synchronous acquisition of signals on both wrists and even multi-channel signals, ensuring monitoring integrity; stable monitoring in the range of 0.1 Hz - 10 kHz, meeting the real-time detection requirements of the pulse frequency; combining the thermal compensation device design of the sensor demodulation module and the temperature shielding characteristics formed by double-wrist fitting to reduce the interference of temperature fluctuations; wavelength resolution ≤ 1 pm, ensuring that minute pulsation signals can also be accurately captured; applicable to bionic pulse simulation at the medical care end, providing a high-fidelity data source for subsequent traditional Chinese medicine pulse diagnosis. The multi-channel parallel demodulation fiber Bragg grating sensing system is applicable to the health monitoring scenario based on bracelet wearing. The sensing system realizes synchronous acquisition of the pulsation signals on both wrists through an optical path unit composed of an SOA broadband light source, an adjustable FP filter, and an optical splitter, and dynamically demodulates the user's pulsation signal waveform by combining the sawtooth wave voltage-driven piezoelectric ceramic tuning technology and the PSD photodetection module. The system integrates a thermal expansion device temperature compensation device to form a double temperature shield with the user's double-wrist fitting wearing method to ensure the measurement accuracy. The real pulsation signals after demodulation can be further transmitted to the medical care end, and the pulse waveform is reproduced through a bionic vibration device and applied to the traditional Chinese medicine remote pulse diagnosis scenario.
[0053] In summary, the fiber Bragg grating sensor health monitoring method provided by the above embodiments generates a sensor data verification prompt message when a user issues a request to obtain a pulsation signal using the fiber Bragg grating sensor. The fiber Bragg grating sensor is located along the central position in the thickness direction of the bracelet and has the same bending curvature as the monitoring bracelet. The sensor data verification prompt message includes a bilateral wrist alignment prompt message. Bilateral pulsation signals are collected based on the fiber Bragg grating sensor, and the monitoring bracelet is worn on one of the user's wrists. The sensor data is verified according to the signal relationship of the bilateral pulsation signals to obtain the true pulsation signal of the user. The tightness of the bracelet is automatically judged by comparing the bilateral signal intensities, without the need for the user to perceive it by themselves, avoiding data distortion caused by loose wearing and poor contact. The similarity of the bilateral pulse waveforms and the phase synchronization index are used to real-time determine whether the user's two wrists are properly attached, further eliminating errors caused by posture deviation. The overall method combines physical structure design and signal verification algorithms to ensure that the collected data has high stability and high credibility, and is particularly suitable for scenarios with high requirements for signal accuracy such as remote pulse diagnosis and chronic disease monitoring. The user only needs to attach the two wrists according to the prompt, and the system automatically verifies the whole process, reducing the dependence on the user's wearing experience and improving the user experience. There is no need to add additional pressure, temperature or attitude sensors, and the whole process verification is directly realized by using the signals of the fiber Bragg grating sensor itself, saving hardware costs. After the two wrists are attached, the sensor is wrapped between the two wrists on both sides, naturally forming a relatively closed and temperature-balanced small environment, which can significantly reduce the influence of environmental temperature changes on the wavelength drift of the fiber Bragg grating.
[0054] In one embodiment, the verifying the sensor data according to the signal relationship of the bilateral pulsation signals to obtain the true pulsation signal of the user includes:
[0055] When the intensities of the bilateral pulsation signals collected by the fiber Bragg grating sensor are the same, a radian recovery confirmation message indicating that the radian of the fiber Bragg grating sensor is in the recovery state is generated;
[0056] The pulsation signal collected after the radian recovery confirmation message is generated is recorded as the true pulsation signal of the user.
[0057] Exemplarily, when the user wears the bracelet, the fiber Bragg grating sensor starts to synchronously collect the pulsation signals at the wrist on the wearing side and the opposite wrist. Since the fiber Bragg grating sensor is located at the center position in the thickness direction of the bracelet and presents a curved arc in the natural state, only when the user's both wrists are closely attached, the original arc of the sensor will be unfolded and flattened, and the contact area and distance with the left and right wrists are symmetrically consistent. The system compares the intensities of the bilateral pulsation signals in real time, specifically by detecting the peak amplitudes of the signals on both sides and calculating the intensity difference. If it is detected that the signal intensities on both sides are the same or the difference is lower than the preset threshold, it indicates that the wearing is appropriately tight and the bilateral wrists are well aligned, and the sensor has been restored from the curved state to the straight state. When the condition that the bilateral pulsation signal intensities are the same is satisfied, the system automatically generates an arc recovery confirmation message. This confirmation message indicates that the current monitoring bracelet has completely unfolded the original arc of the fiber Bragg grating sensor to the straight state under the operations of the user wearing and the bilateral wrists being aligned and closely attached; the wearing tightness and contact pressure are both in the ideal monitoring state; the subsequent pulsation signal acquisition process has high stability and accuracy. This confirmation message can be displayed on the device interface or the APP to prompt the user that the wearing is correct, and at the same time, it also serves as an internal mark of the system to start the formal data acquisition process. After generating the arc recovery confirmation message, the system starts to record the pulsation signal data collected in this state as the user's real pulsation signals. This step ensures that only the data collected under the premise that the sensor arc is unfolded and the wearing state is stable is considered valid; it can effectively avoid signal distortion caused by loose wearing, non-closely attached wrists or sensor position deviation; these subsequent real pulsation signals can be used in various medical scenarios such as health assessment and remote diagnosis and treatment.
[0058] It can be understood that by utilizing the arrangement structure characteristics of the fiber Bragg grating sensor, that is, being located at the center of the bracelet and naturally in an arc state combined with the symmetric structure of the user's both wrists, by judging the physical phenomenon that the bilateral pulsation signal intensities are the same, it is indirectly deduced whether the wearing state of the bracelet is standard and whether the arc of the sensor has been flattened and unfolded. In the arc-unfolded state, the left and right wrists are closely attached, the contact area of the sensor is symmetric, and the bilateral pulse signal intensities are naturally the same; conversely, if the wearing is loose or the wrists are not aligned, there will be a detectable difference in the signal intensities. Thus, the system does not require additional hardware and can judge the wearing tightness and position alignment situation relying on the existing pulse signals, simplifying the device structure. Only the data collected after confirming the arc unfolding is recorded to avoid miscollecting signals in the unstable state. The user only needs to closely attach both wrists according to the prompt without having to judge whether the wearing is standard by themselves, reducing the usage threshold. It is applicable to scenarios such as remote pulse diagnosis and health monitoring to ensure the authenticity and reliability of the data transmitted to the medical staff side.
[0059] Exemplarily, when the user wears the bracelet, the system prompts "Please align and press the wrists tightly together". After the user's operation, the system detects that the pulsation signal intensities of the left and right wrists are the same, and immediately generates a "radian recovery confirmation message", prompting "Wearing is normal, start monitoring". All subsequent pulsation data acquisitions are based on this confirmation status, ensuring the stability and accuracy of the data, and finally it can be safely uploaded to the medical platform for doctors to analyze.
[0060] Exemplarily, in an air-conditioned environment, traditional single-sided worn fiber Bragg grating sensors are extremely vulnerable to local temperature changes, resulting in measurement errors. In this embodiment, by guiding the user to press the two wrists tightly together and placing the sensor between the two wrists, a small environment with stable body temperature is formed, effectively isolating the environmental temperature fluctuations. Even if the user is in an indoor-outdoor environment with drastic temperature differences, the stability and accuracy of the signal can still be guaranteed, providing reliable health data for the user and the doctor.
[0061] In one embodiment, the verifying the sensor data according to the signal relationship of the bilateral pulsation signals to obtain the true pulsation signal of the user includes:
[0062] When the intensities of the bilateral pulsation signals collected by the fiber Bragg grating sensor are the same, generating a radian recovery confirmation message indicating that the radian of the fiber Bragg grating sensor is in a recovery state;
[0063] Generating a pressure monitoring instruction based on the radian recovery confirmation message to obtain the pressure signal between the current wrist and the bracelet as the target pressure;
[0064] After obtaining the target pressure, generating a bilateral wrist separation prompt message to generate a bracelet wearing length adjustment message after the bilateral wrists are separated;
[0065] Continuing to monitor the pressure signal, and when the pressure signal reaches the target pressure again, generating an adjustment completion message to obtain the true pulsation signal of the user based on the current bracelet state.
[0066] Exemplarily, after the user wears the monitoring bracelet, the system starts the fiber Bragg grating sensor to synchronously collect the pulsation signals of the wrist on the wearing side and the opposite side. The fiber Bragg grating sensor is set at the central position in the thickness direction of the bracelet and presents a bending arc in the natural state. The user aligns the two wrists according to the prompt. When the system detects that the intensities of the bilateral pulsation signals are the same or the difference is lower than the set threshold, it is determined that the current bracelet wearing state is stable, the wrists are aligned and pressed tightly, and at the same time, the original arc of the sensor has been unfolded and flattened. At this time, the system generates an arc recovery confirmation message, indicating that the bracelet is in the standard fitting state. After generating the arc recovery confirmation message, the system further issues a pressure monitoring instruction to start the pressure sensing module to collect the pressure signal between the inner side of the current bracelet (the sensor contact surface) and the user's wrist skin. This pressure signal corresponds to the standard pressure value formed in the state of double-wrist fitting and arc recovery, and the system records it as the target pressure. This target pressure represents that the tightness of the bracelet is most suitable in the current wearing state, which can ensure that the fitting degree of the bracelet during subsequent single-wrist wearing is consistent with this state, thereby ensuring the stability and accuracy of the pulsation signal. After the target pressure is recorded, the system generates a bilateral wrist separation prompt message, prompting the user to release the two wrists and only keep the bracelet on the wearing side. This step ensures that the user's operation is orderly in the subsequent wearing adjustment link, and avoids the user missing the adjustment by mistakenly thinking that the detection has been completed. After the two wrists are separated, the system continues to monitor the pressure signal between the current wearing-side wrist and the bracelet according to the previously obtained target pressure value, and prompts the user to adjust the length or tightness of the bracelet. If the current pressure signal is lower than the target pressure, the system prompts "Please tighten the bracelet"; if the pressure is too high, it prompts "Please appropriately loosen the bracelet" to guide the user to adjust the wearing state to be consistent with the target pressure. This process is dynamically presented in the form of a device interface, an APP interface, or vibration feedback, etc. During the process of the user adjusting the length of the bracelet, the system continuously monitors the current pressure signal. When it detects that the pressure signal reaches the previously recorded target pressure value again, the system generates an adjustment completion message, prompting the user that the current wearing length has been adjusted to the appropriate state. At the same time, the system confirms that the current bracelet wearing state is the same as that when the two wrists were fitted before, the arc is unfolded and the contact pressure is appropriate, and officially starts to collect the user's real pulsation signal, and records or uploads the data to the remote medical platform. Thus, not only relying on the arc unfolding, but also further refining to the pressure value, precise wearing adjustment is realized. The wrist circumferences and habits of each user are different, and the system dynamically collects the optimal wearing pressure for each individual to avoid discomfort or measurement errors caused by unified setting. After the wearing length adjustment is completed, the system ensures that it is the same as the double-wrist fitting state, and the pulse signal is more real and has good repeatability. During the operation process, each step has a clear prompt to reduce misoperation and is suitable for various groups of people, including elderly users. When the two wrists are fitted, the sensor is covered between the two wrists to form a closed space. At the same time, after the target pressure is determined, the wearing state is stable, which can effectively reduce the influence of temperature change on the wavelength drift of the fiber Bragg grating.
[0067] For example, a user wears a smart bracelet and is about to perform daily pulse monitoring. The system prompts "Please press both wrists together". After the user's operation, the system detects that the signal intensities on both sides are the same, generates an arc reply confirmation message, and records the current pressure value as the target pressure. Then the system prompts "Please release both wrists and adjust the length of the bracelet". The user gradually tightens or loosens the bracelet, and the device interface shows the change of the current pressure value in real time. When the pressure reaches the target pressure, the system prompts "Adjustment completed" and starts to collect the formal pulse signal. The whole process requires no professional guidance, has clear operations, and standardized wearing, greatly improving the signal stability and user experience.
[0068] In one embodiment, the step of verifying the sensor data according to the signal relationship of the bilateral pulsation signals to obtain the true pulsation signal of the user includes:
[0069] When the intensities of the bilateral pulsation signals collected by the fiber Bragg grating sensor are the same, generating an arc reply confirmation message indicating that the arc of the fiber Bragg grating sensor is in the recovery state;
[0070] Generating a pressure monitoring instruction based on the arc reply confirmation message to obtain the pressure signal between the current wrist and the bracelet as the target pressure;
[0071] After obtaining the target pressure, generating a message prompting the separation of the bilateral wrists, so that after the bilateral wrists are separated, the wearing length of the bracelet is automatically adjusted until the pressure signal reaches the target pressure again, so as to obtain the true pulsation signal of the user based on the current bracelet state.
[0072] Exemplarily, after the user wears the monitoring bracelet, the system synchronously collects the pulsation signals of the wrist on the wearing side and the opposite wrist through the fiber Bragg grating sensor. Since the fiber Bragg grating sensor is arranged at the central position in the thickness direction of the bracelet and has a bending arc in the natural state, the user aligns the bilateral wrists closely according to the prompt. When the system detects that the intensities of the bilateral pulsation signals are the same or the intensity difference is lower than the preset threshold, it indicates that the user's double wrists are properly fitted, and the original arc of the sensor has been unfolded to a flat state, with the contact area and the fitting pressure being symmetrically consistent. At this time, the system generates a curvature recovery confirmation message to confirm that the current wearing state meets the standard monitoring requirements. After generating the curvature recovery confirmation message, the system issues a pressure monitoring instruction to activate the built-in pressure sensor module to collect the pressure signal between the user's wrist and the bracelet in real time in this state, and records this pressure signal as the target pressure. This pressure value reflects the best fitting state of the user when wearing the bracelet, with the double wrists closely attached and the arc of the bracelet flattened, and is the basis for subsequent automatic adjustment of the wearing length. After the target pressure is recorded, the system generates a bilateral wrist separation prompt message to prompt the user to loosen the double wrists and maintain the wearing state of a single bracelet to prepare for the subsequent automatic adjustment process. After the user's double wrists are separated, the system activates the automatic adjustment mechanism inside the bracelet (such as a buckle controlled by a micro stepping motor or a flexible material drive structure), dynamically detects the current pressure signal, and gradually adjusts the wearing length of the bracelet according to the difference between the real-time pressure and the target pressure. If the current pressure is lower than the target pressure, the bracelet is automatically tightened; if the pressure is too high, the wearing length is appropriately relaxed; during the adjustment process, the system continuously monitors the pressure change until the current pressure signal reaches the previously recorded target pressure value again. This process does not require user intervention and is automatically completed by the system according to the pressure feedback. When the pressure signal is adjusted to be consistent with the target pressure, the system generates an adjustment completion status to confirm that the current wearing state is the same as when the double wrists are fitted, the arc of the fiber Bragg grating sensor is in the recovery state, and the contact pressure is appropriate. At this time, the system officially collects the user's real pulsation signal and uses the data for health assessment or remote diagnosis and treatment scenarios. Thus, without manual adjustment by the user, the system automatically detects the pressure and controls the wearing length, reducing the operation complexity and human error. Each detection uses the target pressure as a reference, and the wearing state is the same as when the double wrists are fitted, avoiding data instability caused by fluctuations in the daily wearing tightness. The pulsation signal is collected only when the curvature recovers and the pressure meets the standard, effectively eliminating the noise caused by wearing deviation. The operation process is simplified, and the user only needs to fit the double wrists once, and the rest of the adjustment process is automatically completed, especially suitable for the elderly or users who are not familiar with the device. The process of fitting the double wrists forms a closed temperature environment, and the subsequent wearing pressure is standardized, further reducing the influence of environmental temperature changes on the sensor.
[0073] For example, in daily health monitoring of a user, after wearing a bracelet, the system prompts "Please press both wrists tightly together". After the user's operation, the system detects that the signal strengths on both sides are the same, confirms that the arc has been unfolded, and collects the current pressure value as the target pressure. Subsequently, it prompts "Please release both wrists", and the system automatically starts the internal stepper motor to finely adjust the wearing length, dynamically detecting the pressure until the target pressure is reached. The system then prompts "Adjustment completed", and officially collects the pulse data, without the need for the user to manually adjust during the whole process.
[0074] In one embodiment, it further includes:
[0075] Before analyzing the relationship between the intensities of the bilateral pulsation signals collected by the fiber Bragg grating sensor, analyze the phase relationship of the bilateral pulsation signals collected by the fiber Bragg grating sensor, so as to perform the analysis operation of the relationship between the intensities of the bilateral pulsation signals collected by the fiber Bragg grating sensor when the phase relationship indicates that the periods of the bilateral pulsation signals are synchronized.
[0076] It can be understood that before judging the relationship between the intensities of the bilateral pulsation signals, the phase relationship is analyzed first, and only when the phase synchronization is confirmed, the intensity comparison is carried out. This strategy can further enhance the robustness of the wearing state judgment and avoid misjudgment caused by transient noise or non-standard fitting actions.
[0077] Exemplarily, the user wears a monitoring bracelet and aligns and presses the worn side and the unworn side of the wrist tightly according to the prompt. The fiber Bragg grating sensor starts to synchronously collect the pulsation signal data from both wrists, including signal waveform, amplitude and phase information. The system first performs a phase synchronization analysis on the collected pulsation signals from both sides. Specifically, by comparing indicators such as the periodicity, waveform peak time points, and phase differences of the pulse signals on both sides, it is judged whether there is a significant phase shift between the pulsation signals on both sides. If the phase difference between the pulsation signals on both sides is lower than the set threshold, it is considered that the pulsation signals on both sides are in a cycle synchronization state; if the phase difference exceeds the threshold, the user is prompted to adjust the wrist alignment or wearing posture, and subsequent analysis is not performed temporarily. Through this step, the influence of instantaneous phase asynchronization caused by misaligned wrists, poor local contact, or slight hand movements of the user on subsequent judgments is avoided. Only after confirming the phase synchronization of the pulsation signals on both sides does the system continue to perform a signal intensity consistency analysis. At this time, the system detects the peak amplitude of the pulsation signals on both sides and calculates their intensity difference. If the intensity difference between the two-sided signals is within the preset range (such as ±Δ threshold), the system determines that the current bracelet wearing state is appropriately tight, the bracelet arc has been unfolded flat, and a message confirming the arc recovery is generated. Based on the message confirming the arc recovery, a pressure monitoring instruction is started, and the target pressure in the current wearing state is recorded; a message prompting the separation of both wrists is generated to prompt the user to loosen the opposite wrist; the bracelet wearing length is automatically adjusted, and according to the real-time pressure feedback, it is adjusted to the target pressure; after confirming that the pressure meets the standard, the real pulsation signal of the user is collected. Thus, taking the phase relationship analysis as a prerequisite and utilizing the periodic synchronization characteristics of the physiological pulse signal to ensure that the signals on both sides are naturally synchronized when the wearing state is good. The signal offset caused by short-term external disturbances or irregular user operations is excluded through phase synchronization detection, improving the robustness and accuracy of the overall judgment logic. Analyzing the phase synchronization first effectively avoids misjudging the signal intensity due to transient noise or incomplete fitting of the user. Only on the premise that both wrists are fully fitted and the pulse signals are cycle-synchronized, does it enter the intensity analysis and subsequent adjustment process to prevent the system from entering the adjustment link due to short-term posture changes. The phase synchronization as a pre-judgment condition makes the finally confirmed real pulsation signal have higher stability and credibility. If the user's wearing or the fitting operation of both wrists is not in place, the system can timely remind the user to adjust through phase offset detection, reducing the risk of miscollection.
[0078] For example, when the user wears the bracelet and is ready to perform pulse detection, the system first analyzes the phases of the bilateral pulsation signals. Only when the peak time synchronization of the waveforms on both sides is detected to be good can it enter the intensity comparison stage. If a large phase deviation is detected, the system prompts "Please adjust the fit of both wrists" to avoid misjudging the wearing state due to slight movements or improper wearing. This can ensure that the data collected subsequently has high consistency and authenticity. Introducing the phase synchronization analysis as a precondition makes the determination logic more rigorous and the anti-interference ability stronger compared to the solution that only relies on signal intensity comparison. Combining the arc expansion determination, pressure adjustment, and automatic length adjustment to achieve a complete closed-loop wearing optimization solution, which is applicable to scenarios with extremely high requirements for data accuracy such as high-precision health monitoring and remote medical treatment.
[0079] According to some embodiments, it further includes:
[0080] Sending the collected real pulsation signal to the medical staff side.
[0081] In one embodiment, it further includes:
[0082] Simulating the real pulsation signal received at the medical staff side.
[0083] Exemplarily, after the user wears the bracelet to complete the wearing state verification, pressure adjustment, and real pulsation signals have been collected, the system sends the collected pulsation signal data to the medical staff's device through the communication module. The sent signal data may include, but is not limited to: complete pulsation waveform data; information such as sampling timestamp, period, amplitude, phase, etc.; corresponding wearing state parameters, such as target pressure value, arc recovery confirmation information, etc. The data can be securely encrypted and transmitted through methods such as 4G / 5G, WiFi, or Bluetooth gateway to ensure data integrity and privacy security. At the medical staff's end, after receiving the real pulsation signal from the user end, the system reproduces the pulse waveform through a preset pulsation signal simulation module. The medical staff's device analyzes the received pulsation signal and restores the pulse period, amplitude, and waveform detail features. Using software and hardware bionic devices, such as a micro servo-driven airbag array, flexible vibration membrane, electromagnetic drive array, etc., the analyzed pulse signal is reproduced on the physical device. Medical staff can perceive the strength, rhythm, and fluctuation details of the pulse through the pulsation waveform simulated on the finger touch device, as if taking the patient's pulse on the spot. Medical staff feel the pulse on the bionic device with their fingers, combine the waveform characteristics of the pulse signal with traditional Chinese medicine syndrome differentiation experience, and complete the judgment of the traditional Chinese medicine pulse condition of the patient. For example, it can distinguish types such as floating pulse, sinking pulse, stringy pulse, slippery pulse, etc., and at the same time combine the patient's past medical history and other data for overall diagnosis to achieve the effect of remote traditional Chinese medicine pulse diagnosis. By collecting real and stable pulsation signals at the user end, transmitting them intact to the medical staff's end, and then using physical bionic technology to reproduce the pulsation signals, it is ensured that medical staff can accurately perceive the patient's pulse state just like taking the pulse face to face. Thus, the user end ensures the authenticity and effectiveness of the signal through steps such as arc expansion and pressure adjustment; the medical staff's end uses a high-precision bionic vibration / pneumatic / electromagnetic simulation system to restore the pulse details; the remote communication technology ensures the real-time nature and security of the data. It solves the limitation that traditional Chinese medicine pulse diagnosis needs to be operated face to face, improves the coverage and efficiency of remote medical treatment. By highly restoring the user's real pulsation signal, medical staff can directly diagnose through touch, improving the accuracy of pulse condition discrimination. Using secure encrypted communication technology protects the privacy of users and at the same time ensures that the pulse data is delivered in real time. Whether the patient is at home, in the community, or in a remote area, they can receive professional traditional Chinese medicine pulse diagnosis services through this system. For example, when a patient wears a bracelet at home to complete pulse detection, the system collects a real pulsation signal through the arc recovery confirmation + pressure adjustment process, and then sends the signal to the hospital through an encrypted channel. After the hospital medical staff's device receives the signal, it restores the pulse fluctuation at a specific position through the servo airbag array device, and the doctor directly palpates with traditional techniques to judge the patient's pulse condition, realizing remote diagnosis.
[0084] Exemplarily, the medical end pulse simulation solution based on real pulsation signals may include using a flexible piezoelectric film to simulate the pulsation signal. At the medical end, a flexible piezoelectric film (such as a PVDF material) is set as the bionic pulse output device. The piezoelectric film has good flexibility and response speed, and can drive its local vibration according to the input voltage to simulate the pulsation signal. After receiving the real pulsation signal from the user end, the system analyzes the signal into amplitude, frequency, and period parameters. The control module drives the flexible piezoelectric film to vibrate in real time according to the analyzed signal to reproduce the pulse waveform. Medical staff can perceive the same pulsation rhythm and strength as the user by touching the surface of the film with their fingers. It has the technical effects of sensitive signal response, can restore pulse details meticulously, simple structure, strong durability, suitable for high-frequency use in medical care places, and applicable to single-point palpation or multi-point array expansion.
[0085] Exemplarily, the medical end pulse simulation solution based on real pulsation signals may include a method of using an electromagnetic coil array in cooperation with an elastic membrane to simulate the pulsation signal. At the medical end, an electromagnetic coil array is set, and an elastic membrane is covered above it. The pulsation signal drives the coil by regulating the current, driving the surface of the membrane to form periodic vibrations. The real pulsation signal can be analyzed to extract rhythm and amplitude data. By controlling the on-off current of multiple micro electromagnetic coils, the local agitation of the elastic membrane can be driven. It supports synchronous driving at multiple positions and can reproduce the pulses at the cun, guan, and chi positions simultaneously. It has the technical effects of controllable amplitude, fast response speed, strong realism of pulse simulation, supporting reproduction of multiple pulses, applicable to the multi-finger pulse diagnosis operation in traditional Chinese medicine, modular structure, and convenient for maintenance and expansion.
[0086] Exemplarily, the medical end pulse simulation solution based on real pulsation signals may include a method of using a micro airbag array in cooperation with an air pump system to simulate the pulsation signal. A micro airbag array is adopted, and by controlling the inflation and deflation rhythm of the air pump and electromagnetic valves, the surface pulsation bionics is realized. After the real pulsation signal is transmitted to the medical end, the system can control the micro air pump to inflate at the same rhythm. The local expansion and contraction of the airbag restore the pulse fluctuation. The pressure difference of different airbag areas can be set to simulate the strength difference between the left and right pulses or specific pulse conditions. It has the technical effects of real feedback, high softness, easy to be accepted by the pulse diagnosis habit of traditional Chinese medicine, and can highly simulate pulse types with different strengths and rhythms.
