[0039] The embodiments of the present application provide a fiber grating sensor health monitoring method and system, which can solve the problems of unstable signals, signal interference and the like in the process of physiological signal collection of the fiber grating sensor in the traditional application, which are limited by wearing methods and external environmental factors, and affect the accuracy and reliability of monitoring data.

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 can include other steps or units not clearly listed or inherent to these processes, methods, products or devices. The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments.
[0041] Please refer to Figure 1 A flowchart of a fiber grating sensor health monitoring method provided by the embodiments of the present application can specifically include S110-S130.
[0042] S110, in the case that a user issues a request for obtaining a pulse signal by using a fiber grating sensor, a sensor data verification prompt message is generated, the fiber grating sensor is arranged along the center position in the thickness direction of a bracelet and has the same bending radius as the monitoring bracelet, and the sensor data verification prompt message includes a bilateral wrist alignment prompt message.
[0043] S120, based on the fiber grating sensor collecting bilateral pulse signals, the monitoring bracelet is worn on one of the wrists of the user.
[0044] S130, according to the signal relationship of the bilateral pulse signals, the sensor data is verified to obtain the real pulse signal of the user.
[0045] It can be understood that the method aims to solve the pulse signal measurement error problem caused by unstable wearing position, tightness and external environment interference of the existing technology. The method is based on the structure design that the fiber grating sensor is arranged symmetrically along the center of the monitoring bracelet thickness direction and has the same natural bending arc as the bracelet. The symmetry and pulse signal similarity of the user's double wrist are used to realize effective verification of the sensor data collection. The core principle is to judge whether the wearing state meets the standard by monitoring the signal strength, waveform similarity and phase synchronization of the double pulse signals, and then to eliminate abnormal signals caused by improper wearing or hand movement, so as to ensure that the real and accurate pulse signal of the user is obtained.
[0046] For example, when the user initiates a pulse detection request actively, the system will automatically generate a sensor data verification prompt message, which includes but is not limited to the prompt content of "aligning and closely fitting the double wrists". At the same time, the user is also prompted to keep still. The prompt message can be conveyed to the user in various ways such as device display screen, mobile phone APP, LED indication or vibration reminder, guiding the user to perform standardized wearing operation, and ensuring that the subsequent collection process has good prerequisites.
[0047] For example, the user aligns and closely fits the wrist of the side without wearing the bracelet with the wrist of the side wearing the bracelet according to the prompt, forming a stable double-sided fitting state. Since the fiber grating sensor is arranged at the center of the thickness direction of the bracelet, and is consistent with the overall bending arc of the bracelet in the natural state, when the wrists are fitted, the distance and contact area of the sensor to the left and right wrists are symmetrical and consistent. The sensor collects the direct pulse signal of the wearing side wrist and the pulse signal conducted through fitting on the other side in real time, and records the amplitude, waveform and phase information of the two signals to form complete original detection data.
[0048] For example, the system analyzes the collected double-sided pulse signals in real time, focusing on completing data verification from the following three dimensions: first, detect whether the difference between the signal strengths of the two sides is within the preset threshold range. Only when the signal strengths of the two sides are close, it indicates that the wearing tightness is moderate and the bracelet arc has been unfolded and flattened, and the contact is good. Second, the system uses signal correlation algorithm (such as Pearson correlation coefficient or DTW dynamic time warping) to compare the similarity of the waveforms of the two sides. Only when the similarity reaches the preset similarity standard (such as more than 90%), it is determined that the user's double wrists are well aligned. Third, the phase synchronization of the two pulse signals is determined by the phase analysis method to confirm whether there is a phase deviation caused by wearing deviation or hand movement. If the above three verification indicators meet the standard, it is determined that the detection data is valid.
[0049] For example, after passing the signal check, the system will eliminate the noise signal caused by loose, misaligned or external interference, and only keep the qualified real pulse signal data as the user's health monitoring result output, 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] For example, in the case of pulse monitoring for middle-aged and elderly users at home, after wearing the bracelet, the user will follow the prompt to attach both wrists. The device will compare the signals in real time and confirm that the signal strength is consistent. It will then output the real pulse signal and upload it to the health management platform for doctor evaluation.
[0051] For example, in the case of remote traditional Chinese medicine diagnosis and treatment, the patient wears the bracelet at home and attaches both hands. The medical staff can receive the pulse waveform after data verification in real time, ensuring that the pulse information obtained by the doctor is real and reliable, and reducing the risk of remote misdiagnosis.
[0052] In some examples, the fiber grating sensor is connected to a multi-channel fiber grating sensor array through an optical splitter, each sensing unit corresponding to the pulse signal collection area of the wearing side wrist and the opposite side wrist respectively, supporting at least two channels or even more channel synchronous signal acquisition, adapting to different wearing states and user wrist types. The sensor array configuration is based on a SOA broadband light source and a tunable Fabry-Perot (FP) filter, supporting high-precision tuning in the wavelength range of 1520 to 1570 nm to adapt to small pulse vibration and temperature strain changes of the human body. The demodulation module can specifically include: a PSD photodetector for receiving reflected signals and converting them into electrical signals in real time to ensure complete signal sampling; a sawtooth wave voltage driven piezoelectric ceramic tuner that dynamically adjusts the light source wavelength to match the pulse changes of the bilateral wrists, realizes high dynamic response, and meets the pulse frequency range of 0.1 Hz to 10 kHz; a thermal expansion device integrated in the demodulation module for automatic compensation of environmental temperature fluctuations, cooperating with the double-wrist physical temperature control characteristics of the scheme to further reduce the interference of temperature drift on signal measurement, and finally ensuring that the temperature compensation error of the user's real pulse signal is within ±0.5℃. The user wears a bracelet and attaches the double-wrist, and the system synchronously collects the bilateral wrist pulse signals through a multi-channel parallel demodulation fiber grating system. The demodulation module is used to quickly demodulate the double-channel reflected signals to obtain real-time wavelength shift data and convert 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 an arc return confirmation message. After collecting the target pressure value, the user's single-wrist state is continuously monitored, and through pressure feedback and length adjustment, the subsequent acquisition conditions are ensured to be stable. The real pulse signal collected has temperature compensation and dynamic response optimization characteristics after demodulation, ensuring that the data is highly stable and reliable. Thus, it supports double-wrist bilateral or even multi-channel signal synchronous acquisition, ensuring monitoring integrity; it stably monitors within the range of 0.1 Hz-10 kHz, meeting the real-time detection needs of pulse frequency; it reduces temperature fluctuation interference combined with the design of the thermal compensation device of the sensor demodulation module and the temperature shielding characteristics formed by the double-wrist attachment; the wavelength resolution is ≤1pm, ensuring that small pulse signals can also be accurately captured; it is suitable for medical end bionic pulse simulation, providing a high-fidelity data source for subsequent traditional Chinese medicine pulse diagnosis. The multi-channel parallel demodulation fiber grating sensing system is suitable for health monitoring scenarios based on bracelet wearing. The sensing system realizes synchronous acquisition of bilateral wrist pulse signals through an optical unit composed of a SOA broadband light source, a tunable FP filter, and an optical splitter, dynamically demodulates the user's pulse signal waveform combined with sawtooth wave voltage driven piezoelectric ceramic tuning technology and PSD photodetection modules. The system integrates a thermal expansion device temperature compensation device, forms double temperature shielding with the user's double-wrist attachment wearing method, and ensures measurement accuracy. The real pulse signal after demodulation can be further transmitted to the medical end to reproduce the pulse waveform through a bionic vibration device, and applied to the scene of traditional Chinese medicine remote pulse diagnosis.
[0053] In summary, the above-mentioned embodiments provide a fiber grating sensor health monitoring method. When a user issues a request for obtaining a pulsatile signal using a fiber grating sensor, a sensor data verification prompt message is generated. The fiber grating sensor is arranged at the center of the thickness direction of the bracelet and has the same bending radius as the monitoring bracelet. The sensor data verification prompt message includes a bilateral wrist alignment prompt message. Based on the fiber grating sensor collecting bilateral pulsatile signals, 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 pulsatile signals to obtain the user's real pulsatile signal. The tightness of the bracelet is automatically determined by comparing the signal intensity of the bilateral signals, without the need for the user to perceive it, avoiding data distortion caused by loose wearing and poor contact. The similarity and phase synchronization indicators of the bilateral pulse waveforms are used to determine whether the user's wrists are properly fitted in real time, further eliminating errors caused by posture deviation. The overall method combines physical structure design and signal verification algorithm to ensure that the collected data has high stability and high credibility, especially suitable for remote diagnosis, chronic disease monitoring, and other scenarios that require high signal accuracy. The user only needs to fit the wrists according to the prompt, and the system automatically verifies throughout the process, reducing the dependence on user wearing experience and improving the user experience. No additional pressure, temperature, or posture sensors are needed, and the whole process of verification is realized directly using the signals of the fiber grating sensor itself, saving hardware costs. After the wrists are fitted, the sensor is covered between the two wrists, 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 grating.
[0054] In one embodiment, the verification of the sensor data according to the signal relationship of the bilateral pulsatile signals to obtain the user's real pulsatile signal includes:
[0055] In the case where the intensities of the bilateral pulsatile signals collected by the fiber grating sensor are the same, an arc recovery confirmation message is generated that the arc radius of the fiber grating sensor is in a recovery state.
[0056] The pulsatile signal collected after the generation of the arc recovery confirmation message is recorded as the user's real pulsatile signal.
[0057] For example, after the user wears the bracelet, the fiber grating sensor starts to synchronously collect the pulsatile signals located at the wearing side wrist and the opposite side wrist. Since the fiber grating sensor is located at the center position of the thickness direction of the bracelet and naturally presents a curved arc, only when the user's two wrists are close together, the original arc of the sensor will be flattened and expanded, and the contact area and distance of the left and right wrists remain symmetrical and consistent. The system compares the intensities of the bilateral pulsatile signals in real time, specifically by detecting the peak amplitudes of the two signals and calculating the intensity difference. If it is detected that the intensities of the two signals are the same or the difference is below a preset threshold, it indicates that the wearing tightness is appropriate, the bilateral wrists are well aligned, and the sensor has been restored from the curved state to the flat state. When the condition that the intensities of the bilateral pulsatile signals are the same is met, the system automatically generates an arc recovery confirmation message. This confirmation message indicates that the current monitoring bracelet has completely expanded the original arc of the fiber grating sensor to a flat state under the operation of the user wearing and the bilateral wrists being close together; the wearing tightness and contact pressure are in an ideal monitoring state; the following pulsatile signal acquisition process has high stability and accuracy. The confirmation message can be displayed on the device interface or the APP to prompt the user to wear correctly, and also serves as an internal flag of the system to start the formal data acquisition process. After generating the arc recovery confirmation message, the system starts to record the pulsatile signal data collected in this state as the real pulsatile signal of the user. This step ensures that only when the sensor arc is expanded and the wearing state is stable, the collected data is considered valid; it can effectively avoid signal distortion caused by loose wearing, non-close wrists, or sensor position deviation; and the subsequent real pulsatile signals can be used for health assessment, remote diagnosis, and other medical scenarios.
[0058] It can be understood that by utilizing the arrangement structure characteristics of the fiber grating sensor, i.e., being located at the center position of the bracelet and naturally presenting an arc state, and the symmetrical structure of the user's bilateral wrists, the same intensity of the bilateral pulsatile signals is determined, which indirectly deduces whether the wearing state of the bracelet is standard and whether the arc of the sensor has been flattened and expanded. In the arc expanded state, the left and right wrists are close together, the contact area of the sensor is symmetrical, and the intensities of the bilateral pulse signals are naturally consistent; otherwise, if the wearing is loose or the wrists are not aligned, there will be a detectable difference in the signal intensity. Therefore, the system does not need additional hardware and can determine the wearing tightness and position alignment based on the existing pulse signals, simplifying the device structure. Only the data collected after confirming the arc expansion is recorded, avoiding the collection of unstable state signals. The user only needs to follow the prompt to close the bilateral wrists, without the need to judge whether the wearing is standard, reducing the use threshold. It is suitable for remote diagnosis, health monitoring, and other scenarios, ensuring that the data transmitted to the medical end is real and reliable.
[0059] For example, the user wears the bracelet, and the system prompts "Please align and close the two wrists". After the user operates, the system detects that the pulse signal strength of the left and right wrists is consistent, immediately generates an "arc recovery confirmation message", and prompts "Wearing is normal, start monitoring". The following pulse data collection is based on this confirmation state, ensuring the stability and accuracy of the data, and finally can be safely uploaded to the medical platform for doctors to analyze.
[0060] For example, in an air-conditioned environment, the traditional single-wearing fiber grating sensor is easily affected by local temperature changes, resulting in measurement errors. However, by guiding the user to close the two wrists, the sensor is placed between the two wrists, forming a small environment with stable body temperature, effectively isolating environmental temperature fluctuations. Even if the user is in an indoor and outdoor environment with large temperature differences, the stability and accuracy of the signal can still be guaranteed, providing reliable health data for users and doctors.
[0061] In one embodiment, the sensor data is verified according to the signal relationship of the bilateral pulse signals to obtain the real pulse signal of the user, comprising:
[0062] In the case that the fiber grating sensor collects the same intensity of bilateral pulse signals, an arc recovery confirmation message is generated that the arc of the fiber grating sensor is in a recovery state;
[0063] Based on the arc recovery confirmation message, a pressure monitoring instruction is generated to obtain the pressure signal between the current wrist and the bracelet as the target pressure;
[0064] After obtaining the target pressure, a bilateral wrist separation prompt message is generated, and after the bilateral wrists are separated, a bracelet wearing length adjustment message is generated;
[0065] The pressure signal is continuously monitored, and in the case that the pressure signal reaches the target pressure again, an adjustment completion message is generated to obtain the real pulse signal of the user based on the current bracelet state.
[0066] For example, after the user wears the monitoring bracelet, the system starts the fiber grating sensor to synchronously collect the pulse signals of the wearing side and the opposite side of the wrist. The fiber grating sensor is arranged at the center position in the thickness direction of the bracelet and presents a curved arc in a natural state. The user aligns the two wrists according to the prompt, and when the system detects that the pulse signal strengths of the two sides are consistent or the difference is lower than a set threshold, it is determined that the current bracelet wearing state is stable, the wrists are aligned and close, and 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 a 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 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 the two wrists being aligned and the arc being recovered, and the system records it as the target pressure. This target pressure represents the most appropriate tightness of the bracelet in the current wearing state, which can ensure that the bracelet fitting degree in the subsequent single-wrist wearing is consistent with this state, thereby ensuring the stability and accuracy of the pulse signal. After the target pressure is recorded, the system generates a two-wrist separation prompt message, prompting the user to loosen the two wrists and only keep the wearing side bracelet. This step ensures that the user's operation is orderly in the subsequent wearing adjustment process, avoiding the user's mistake that the detection has been completed, which leads to adjustment omission. 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 target pressure value obtained previously, 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 loosen the bracelet appropriately", guiding the user to adjust the wearing state to be consistent with the target pressure. This process is dynamically presented in the form of device interface, APP interface or vibration feedback, etc. During the user's adjustment of the length of the bracelet, the system continuously monitors the current pressure signal. When it is detected that the pressure signal reaches the target pressure value recorded previously 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 bracelet wearing state at this time is consistent with the previous two-wrist alignment, the arc is unfolded and the contact pressure is moderate, and the real pulse signal of the user is collected and the data is recorded or uploaded to the remote medical platform. Therefore, not only the arc unfolding is relied on, but also the pressure value is further refined to achieve precise wearing adjustment. The wrist circumference and habits of each user are different, and the system dynamically collects the best wearing pressure of the individual to avoid discomfort or measurement error caused by uniform setting. After the wearing length adjustment is completed, the system ensures that it is consistent with the two-wrist alignment state, and the pulse signal is more real and has good repeatability. During the operation process, there are clear prompts at each step to reduce misoperation and be suitable for all types of people, including elderly users. When the two wrists are aligned, the sensor is covered between the two wrists to form a closed space, and 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 grating.
[0067] For example, a user wears a bracelet for daily pulse monitoring. The system prompts "Please attach both wrists". After the user operates, the system detects that the signal strength of both sides is consistent, generates an arc recovery confirmation message, and records the current pressure value as the target pressure. Then the system prompts "Please loosen both wrists and adjust the bracelet length". The user gradually tightens or loosens the bracelet. The device interface displays the current pressure value in real time. When the pressure reaches the target pressure, the system prompts "Adjustment completed" and starts the formal pulse signal collection. The whole process does not need professional guidance, the operation is clear, the wearing is standardized, and the signal stability and user experience are greatly improved.
[0068] In an embodiment, the sensor data is verified according to the signal relationship of the bilateral pulse signals to obtain the real pulse signal of the user, comprising:
[0069] In the case that the fiber grating sensor collects bilateral pulse signals with the same intensity, an arc recovery confirmation message is generated that the arc of the fiber grating sensor is in a recovery state;
[0070] Based on the arc recovery confirmation message, a pressure monitoring instruction is generated to obtain the pressure signal between the current wrist and the bracelet as the target pressure;
[0071] After obtaining the target pressure, a bilateral wrist separation prompt message is generated. After the bilateral wrist separation, the bracelet wearing length is automatically adjusted until the pressure signal reaches the target pressure again, so as to obtain the real pulse signal of the user based on the current bracelet state.
[0072] For example, after the user wears the monitoring bracelet, the system synchronously collects the pulsatile signals of the wearing side wrist and the contralateral wrist through the fiber grating sensor. Since the fiber grating sensor is arranged at the center position in the thickness direction of the bracelet, and has a curved arc in the natural state, the user aligns the bilateral wrists according to the prompt. When the system detects that the intensity of the bilateral pulsatile signals is the same or the intensity difference is lower than the preset threshold, it indicates that the user's bilateral wrists are in place, the original arc of the sensor has been unfolded to a flat state, and the contact area and the fitting pressure are symmetrical and consistent. At this time, the system generates an arc recovery confirmation message to confirm that the current wearing state meets the standard monitoring requirements. After generating the arc recovery confirmation message, the system issues a pressure monitoring instruction, starts the built-in pressure sensor module, and collects the pressure signal between the user's wrist and the bracelet in this state in real time, and records the pressure signal as the target pressure. This pressure value reflects the best fitting state of the user wearing the bracelet, aligning the bilateral wrists, and flattening the arc of the bracelet, and is the basis for subsequent automatic adjustment of the wearing length. After recording the target pressure, the system generates a bilateral wrist separation prompt message to prompt the user to release the bilateral wrists and maintain a unilateral bracelet wearing state to prepare for the subsequent automatic adjustment process. After the user's bilateral wrists are separated, the system starts the automatic adjustment mechanism (such as a buckle controlled by a micro stepping motor or a flexible material driving structure) inside the bracelet, dynamically detects the current pressure signal, and 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 loosened; during the adjustment process, the system continuously monitors the pressure change until the current pressure signal again reaches the previously recorded target pressure value. 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 state, confirming that the current wearing state is consistent with the bilateral wrist fitting state, the arc of the fiber grating sensor is in the recovery state, and the contact pressure is appropriate. At this time, the system formally collects the real pulsatile signal of the user and uses the data for health assessment or remote diagnosis and treatment scenarios. In this way, the system automatically detects the pressure and controls the wearing length without manual adjustment, reducing the complexity of operation and human error. Each detection is referenced to the target pressure, the wearing state is consistent with the bilateral wrist fitting state, and the data is stable without daily wearing tightness fluctuations. Only when the arc is recovered and the pressure meets the standard, the pulsatile signal is collected, effectively eliminating the noise caused by wearing deviation. The operation process is simplified, and the user only needs to align the bilateral wrists once, and the rest of the adjustment process is automatically completed, which is especially suitable for the elderly or users who are not familiar with the device. The bilateral fitting process 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, as a user daily health monitoring, wearing bracelet system prompts "please double wrist close". After the user operation, the system detects that the bilateral signal strength is consistent, confirms that the arc has been expanded, and collects the current pressure value as the target pressure. Then prompt "please release double wrist", the system automatically starts the internal step motor fine-tuning wearing length, dynamic detection pressure, until the target pressure is reached, the system prompts "adjustment is completed", the formal collection of pulse data, the whole process does not need the user to manually adjust.
[0074] In an embodiment, further comprising:
[0075] Before analyzing the relationship between the intensities of the bilateral pulsatile signals collected by the fiber grating sensor, the phase relationship of the bilateral pulsatile signals collected by the fiber grating sensor is analyzed, so that the analysis operation of the relationship between the intensities of the bilateral pulsatile signals collected by the fiber grating sensor is performed again in the case that the phase relationship indicates that the periods of the bilateral pulsatile signals are synchronized.
[0076] It can be understood that before judging the relationship between the intensities of the bilateral pulsatile signals, the phase relationship is analyzed first, and only under the premise of confirming the phase synchronization, the intensity comparison is performed. This strategy can further enhance the robustness of the wearing state judgment, and avoid false judgment caused by transient noise or non-standard fitting action.
[0077] For example, the user wears a monitoring bracelet and aligns the wearing side with the non-wearing side of the wrist according to the prompt. The fiber grating sensor starts to synchronously collect the pulsatile signal data from the bilateral wrists, including signal waveform, amplitude and phase information. The system first analyzes the phase synchronization of the collected bilateral pulsatile signals. Specifically, by comparing the periodicity, waveform peak time point, phase difference and other indicators of the bilateral pulse signals, it is determined whether there is a significant phase offset between the bilateral pulsatile signals. If the phase difference of the bilateral pulsatile signals is below the set threshold, it is considered that the bilateral pulsatile signals are in a periodic synchronization state; if the phase difference exceeds the threshold, the user is prompted to adjust the wrist alignment or wearing posture, and the subsequent analysis is temporarily not performed. Through this step, the transient phase asynchronization caused by the user's wrist misalignment, local poor contact or slight hand movement is avoided to affect the subsequent judgment. Only after confirming the phase synchronization of the bilateral pulsatile signals, the system continues to perform signal strength consistency analysis. At this time, the system detects the peak amplitude of the bilateral pulsatile signals and calculates the strength difference. If the bilateral signal strength difference is within the preset range (such as ±Δ threshold), the system determines that the current bracelet wearing state is appropriate, the bracelet curvature has been unfolded and flattened, and a curvature recovery confirmation message is generated. Based on the curvature recovery confirmation message, a pressure monitoring instruction is started, the target pressure under the current wearing state is recorded; a bilateral wrist separation prompt message is generated to prompt the user to loosen the opposite wrist; the bracelet wearing length is automatically adjusted according to the real-time pressure feedback to adjust to the target pressure; the pressure is confirmed to meet the standard, and the real pulsatile signal of the user is collected. Therefore, the phase relationship analysis is used as a prerequisite, and the periodic synchronization characteristics of the physiological pulse signal are used to ensure that the bilateral signals are naturally synchronized when the wearing state is good. The phase synchronization detection excludes the signal offset caused by short-term external disturbance or user's non-standard operation, and improves the robustness and accuracy of the overall judgment logic. The phase synchronization is analyzed first, which effectively avoids the misjudgment of signal strength caused by transient noise or user's incomplete fitting. Only when the two wrists are completely fitted and the pulse signals are periodically synchronized, the strength analysis and subsequent adjustment process are entered, so as to prevent the system from entering the adjustment link due to temporary posture change. The phase synchronization as a prerequisite for determination makes the final confirmed real pulsatile signal have higher stability and credibility. If the user's wearing or bilateral wrist fitting operation is not in place, the system can remind the user to adjust in time through phase offset detection, reducing the risk of false sampling.
[0078] For example, when a user wears the bracelet for pulse detection, the system first analyzes the phase of the bilateral pulsatile signals and detects that the peak time of the waveforms on both sides is in good synchronization, and then enters the intensity comparison link. If the phase deviation is too large, the system prompts "Please adjust the double-wrist fit" to avoid misjudgment of the wearing state due to slight movement or improper wearing. In this way, the data collected subsequently can have high consistency and authenticity. The introduction of phase synchronization analysis as a precondition makes the determination logic more rigorous and the anti-interference ability stronger compared to the scheme that only relies on signal intensity comparison. Combined with the arc expansion determination, pressure adjustment, and automatic length adjustment, a complete closed-loop wearing optimization scheme is realized. It is suitable for high-precision health monitoring, remote medical treatment, and other scenarios with extremely high requirements for data accuracy.
[0079] According to some embodiments, further comprising:
[0080] Sending the collected real pulsatile signals to a medical care end.
[0081] In one embodiment, further comprising:
[0082] Simulating the received real pulsatile signals at the medical care end.
[0083] Exemplarily, after the user wears the bracelet to complete the wearing state verification, pressure adjustment, and the real pulsatile signal has been collected, the system sends the collected pulsatile signal data to the medical care end device through the communication module. The sent signal data can include but is not limited to: complete pulsatile waveform data; sampling time stamp, period, amplitude, phase and other information; corresponding wearing state parameters such as target pressure value, radian recovery confirmation information, etc. The data can be transmitted securely and encrypted through 4G / 5G, WiFi or Bluetooth gateway and the like, to ensure data integrity and privacy security. After receiving the real pulsatile signal from the user end at the medical care end, the system reproduces the pulse waveform through the preset pulsatile signal simulation module, the medical care end device analyzes the received pulsatile signal, and restores the pulse period, amplitude, waveform detail characteristics. The analyzed pulse signal is reproduced on the physical device by using software and hardware bionic devices such as a miniature servo-driven air bag array, a flexible vibration membrane, an electromagnetic driving array, etc. Medical personnel can perceive the pulse strength, rhythm, fluctuation details through the simulated pulsatile waveform on the finger touch device, as if they are palpating the pulse of the patient on site. Medical personnel palpate the pulse on the bionic device, combine the waveform characteristics of the pulse signal with the experience of TCM syndrome differentiation, and complete the TCM pulse condition judgment of the patient. For example, it can distinguish types such as floating pulse, sinking pulse, string pulse, slippery pulse, etc., and make overall diagnosis combined with the patient's past medical history and other data, to achieve the effect of remote TCM pulse diagnosis. By collecting real and stable pulsatile signals at the user end, and transmitting them intact to the medical care end, and then reproducing the pulsatile signals by using physical bionic technology, it ensures that medical personnel can accurately perceive the pulse condition of the patient as if they are face-to-face pulse diagnosis. Therefore, the user end ensures the authenticity and effectiveness of the signal through the steps of radian expansion and pressure adjustment; the medical care end restores the pulse details by using high-precision bionic vibration / air-driven / electromagnetic simulation systems; remote communication technology ensures the real-time and security of data. It solves the limitation of traditional TCM pulse diagnosis which needs face-to-face operation, and improves the coverage and efficiency of remote medical care. By highly restoring the real pulsatile signal of the user, medical personnel can directly diagnose through touch, improving the accuracy of pulse condition identification. By using secure and encrypted communication technology, the privacy of the user is protected, and the pulse data is ensured to be sent in real time. No matter where the patient is, at home, in the community or in a remote area, he or she can receive professional TCM pulse diagnosis services through the system. For example, the patient wears the bracelet at home to complete pulse detection, the system collects real pulsatile signals through the radian recovery confirmation and pressure adjustment process, and then sends the signals to the hospital through an encrypted channel. After receiving the signals at the hospital medical care end device, the doctor restores the pulse fluctuation at a specific position through the servo air bag array device, and directly diagnoses the patient's pulse condition by traditional methods, to achieve remote diagnosis.
[0084] Exemplary, the medical end pulse simulation scheme based on the real pulse signal can include a flexible piezoelectric film to simulate the pulse signal. The medical end sets a flexible piezoelectric film (such as PVDF material) as a 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 pulse signal. After receiving the real pulse 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 personnel can perceive the pulse rhythm and intensity consistent with the user by touching the film surface with their fingers. It has signal response sensitivity, can restore pulse details in detail, has simple structure, strong durability, is suitable for high-frequency use in medical places, and is suitable for single-point palpation or multi-point array expansion.
