Therefore, conducting health risk monitoring for workers is an important prerequisite for ensuring work safety and efficiency, helping to identify physiological abnormalities in a timely manner, optimize work arrangements, and develop personalized safety protection strategies.

[0074] Figure 4 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application.
[0075] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0076] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0077] In the power industry, especially in high-risk work scenarios such as high-voltage transmission and transformation, live-line maintenance, and special inspections, workers often face the dual challenges of complex environmental pressures and physiological strain. Factors such as high altitude, high temperature, high humidity, strong electromagnetic radiation, and prolonged physical labor can easily induce health problems such as fainting, arrhythmia, and heatstroke, which may even lead to personal injury or safety accidents in severe cases. Therefore, conducting health risk monitoring for workers is an important prerequisite for ensuring operational safety and efficiency, helping to identify physiological abnormalities in a timely manner, optimize work arrangements, and develop personalized safety protection strategies.
[0078] In the current technology, the power industry generally uses physiological monitoring equipment (such as heart rate, blood pressure, and pulse oximeter) to obtain the health data of workers, then calculates the current health index of workers, and issues early warnings through static thresholds.
[0079] However, existing health monitoring methods can only identify overt abnormalities (such as tachycardia) and cannot identify latent fatigue at the cellular level, such as cellular metabolic disorders (such as abnormal ion concentrations). Furthermore, they lack linkage analysis with environmental parameters, leading to a risk of missed detections. In addition, static early warning threshold strategies are ill-suited to the dynamic health risks arising from interactions between different workers, different work periods, and complex environments, affecting the accuracy and reliability of monitoring.
[0080] Based on this, this application proposes a health monitoring method. In high-risk work scenarios in the power industry, personnel health risks are usually caused by the combined effects of abnormal physiological states and environmental hazards. Furthermore, considering that changes in the surface potential of human skin are more reflective of cell membrane ion exchange and metabolic activity than traditional physiological parameters, this method is a more sensitive signal for identifying early fatigue and potential health abnormalities. On the other hand, this method identifies external energy stimuli through electromagnetic radiation and equipment vibration, and then integrates potential changes, electromagnetic intensity, and vibration frequency ratios to construct a multi-dimensional health status assessment model. This improves the accuracy and reliability of monitoring the health status of workers and reduces the false negative rate.
[0081] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.
[0082] Figure 1 A flowchart illustrating the physiological state detection method provided in this application embodiment. Figure 1 ;like Figure 1 As shown, the method includes:
[0083] S101. Acquire the potential signal on the surface of the worker's skin and environmental parameters.
[0084] Among these, environmental parameters include electromagnetic radiation and equipment vibration spectrum.
[0085] Optionally, environmental parameters such as electromagnetic radiation and equipment vibration spectrum can be collected using a composite sensor array, that is, using vibration sensors to collect equipment vibration spectrum and electromagnetic sensors to collect electromagnetic radiation.
[0086] Optionally, the potential signal on the worker's skin surface is acquired by a flexible bioelectric detection and microcurrent compensation device integrated into the electrical work protective equipment (such as work clothes and safety helmets). The device has a flexible sensing patch embedded inside and detects the potential signal on the skin surface through a serpentine electrode array.
[0087] It should be noted that designing the flexible electrode into a meandering, serpentine structure (similar to a spring shape) has three advantages:
[0088] First, the serpentine structure can stretch / contract with the skin (conforming to the movement of human joints), preventing rigid electrodes from detaching or causing signal distortion due to limb movement. When the serpentine electrode is placed in the elbow area inside the protective gear for power work, it can extend to more than 130% of its original length when the arm is bent, ensuring it does not break. Second, compared to straight electrodes, the serpentine path increases the contact area between the electrode and the skin, reducing impedance fluctuations caused by sweat and dander. Finally, the meandering structure forms a natural electromagnetic shielding layer, reducing interference from environmental electric fields on bioelectrical signals.
[0089] It is understandable that by acquiring potential signals and environmental parameters, a foundation can be established for the subsequent synchronous perception of human physiological state and working environment conditions, thus laying the groundwork for collaborative monitoring of workers and the environment.
[0090] S102. Process the potential signal according to the signal inversion algorithm to determine the cell ion concentration.
[0091] In one feasible approach, firstly, an adaptive notch filter is used to filter out power frequency interference in the potential signal, and wavelet threshold denoising technology is combined to filter out low-frequency interference in the potential signal to obtain a denoised potential signal; then, the fluctuation variance of the denoised potential signal is calculated based on the number of sampling points; next, the impedance slope of the denoised potential signal is calculated based on a preset frequency band; finally, the cell ion concentration is determined based on the fluctuation variance and the impedance slope.
[0092] It should be understood that in order to improve signal quality, enhance effective information, and reduce noise interference in subsequent analysis, it is necessary to denoise the acquired potential signal. Adaptive notch filters are specifically designed to suppress the 50 Hz power frequency interference commonly found in power systems. Wavelet threshold denoising technology has good time and frequency resolution in processing low-frequency artifacts caused by body movements (such as arm swings and breathing), making it suitable for processing non-stationary biological signals operating in complex environments. Variance can reflect the amplitude and stability of cell membrane potential fluctuations. When fatigued or metabolically disordered, cell membrane ion channels are frequently activated, increasing potential fluctuations. Impedance slope can characterize the trend of skin impedance changes with frequency, indirectly reflecting the sodium ion content in sweat.
[0093] Specifically, the formula for calculating the variance of fluctuation is:
[0094]
[0095] in, Here, represents the variance of the fluctuation; N represents the number of sampling points. This represents the average value of the potential signal.
[0096] It should be noted that when calculating the impedance slope of the denoised potential signal, it is necessary to first perform a short-time Fourier transform or wavelet packet decomposition on the potential signal to obtain the energy spectrum of each frequency component; then, extract the amplitude (or impedance value) corresponding to each frequency point within the preset frequency band (e.g., 0.1 Hz to 100 Hz); finally, use the linear regression formula to calculate the impedance slope of the denoised potential signal.
[0097] Furthermore, the specific formula for determining cell ion concentration is as follows:
[0098]
[0099] in, The calibration coefficients are determined by combining historical testing data; This represents the variance of the fluctuation.
[0100] Understandably, by fusing bioelectrical signals with impedance spectrum characteristics, a mapping relationship between potential and sodium ion concentration is constructed, enabling early prediction of latent metabolic disorders in the human body and providing accurate real-time physiological health assessments for high-risk workers.
[0101] S103. If the cell ion concentration is determined to be within the limit according to the preset threshold, extract the characteristic frequency of the environmental parameters.
[0102] Among them, the characteristic frequencies of environmental parameters are electromagnetic intensity and vibration frequency ratio.
[0103] It should be noted that environmental parameters need to be preprocessed before extracting feature frequencies. Specifically:
[0104] Electromagnetic sensors are used to filter electromagnetic radiation and remove power frequency interference signals.
[0105] It should be understood that power frequency interference (50Hz) is an inherent background noise of the power system, originating from the alternating current of transmission lines and equipment. Its intensity is typically hundreds to thousands of times greater than that of high-frequency radiation. If not separated, it can mask critical high-frequency signals (such as the 100kHz-300MHz radiation generated by partial discharge of equipment). Therefore, it is necessary to separate power frequency interference from high-frequency radiation components before extracting characteristic frequencies.
[0106] S104. Calculate the dynamic equilibrium coefficient based on cell ion concentration, potential signal, and characteristic frequency.
[0107] In one feasible approach, firstly, the cell ion concentration is differentiated to determine the rate of change of cell ion concentration; then, the potential signal is differentiated by the root mean square to determine the potential signal fluctuation rate; finally, the dynamic equilibrium coefficient is calculated based on the rate of change of cell ion concentration, the potential signal fluctuation rate, the electromagnetic intensity, and the vibration frequency ratio.
[0108] Specifically, the formula for determining the rate of change in cell ion concentration is as follows:
[0109]
[0110] Where k is the impedance slope; The calibration coefficients are determined by combining historical testing data; This represents the variance of the fluctuation.
[0111] The specific formula for determining the volatility of a potential signal is as follows:
[0112]
[0113] Where N is the sampling point and V is the potential signal.
[0114] The specific formula for the dynamic balance coefficient is:
[0115] Dynamic equilibrium coefficient = (a × rate of change in cell ion concentration + b × potential signal fluctuation rate) × (c × electromagnetic intensity + d × vibration frequency ratio)
[0116] Where a is the weight of the rate of change of cell ion concentration; b is the weight of the potential signal fluctuation rate; c is the weight of electromagnetic intensity; and d is the weight of the vibration frequency ratio.
[0117] Understandably, by extracting and fusing the dynamic changes in physiological and environmental parameters, a real-time quantitative assessment of the worker's condition can be achieved. Specifically, the rate of change in cell ion concentration reflects the fluctuating trend of the body's metabolic state, the fluctuation rate of electrical potential signals characterizes the dynamic response intensity of nerve or cell membrane excitation levels, and the ratio of electromagnetic intensity to vibration frequency reflects the energy disturbance of the external environment on the human body. By comprehensively calculating the dynamic balance coefficient using these four parameters, it is possible not only to identify whether the current physiological state is stable, but also to predict whether the human body is in a state of stress overload or recovery, thus achieving early warning of latent fatigue and environmental overload.
[0118] S105. Determine the physiological state of the workers based on the dynamic balance coefficient.
[0119] In one feasible approach, it is determined whether the dynamic balance coefficient is less than a preset coefficient; if so, the physiological state is determined to be normal, and the health status detection continues; if not, the physiological state is determined to be abnormal, and safety warning measures are implemented.
[0120] It should be noted that safety warning measures include adjusting equipment parameters, neutralizing the potential signals on the skin surface of workers, and emergency protective procedures.
[0121] It should be understood that by comparing the dynamic balance coefficient with a preset threshold, a rapid classification and response measure can be implemented to assess the current physiological state of the worker. When the dynamic balance coefficient is within the safe threshold (i.e., whether the dynamic balance coefficient is less than the preset coefficient), it indicates that the energy interaction between the internal and external environment of the human body is in a stable state, and health monitoring continues. However, when the coefficient exceeds the safe threshold (i.e., whether the dynamic balance coefficient is greater than the preset coefficient), it indicates that the worker's physiological state may be in an abnormal state such as metabolic disorder, abnormal nerve excitation, or excessive external disturbance, and safety warning measures should be activated immediately. Furthermore, the safety warning measures include a three-level execution mechanism: equipment adjustment, human compensation, and emergency protection. Specifically:
[0122] For the equipment side (adjusting equipment parameters): measures such as dynamically adjusting grounding resistance, suppressing radiation in specific frequency bands, and adjusting equipment parameters (such as reducing electromagnetic radiation and stabilizing vibration frequency) are implemented.
[0123] For the human body side (neutralizing the potential signal on the surface of the worker's skin): microcurrents are released through the tooling electrodes to neutralize abnormal biopotentials.
[0124] Emergency protection measures include measures such as forced power outages, mechanical locking of electrical equipment, and drone-guided evacuation.
[0125] Understandably, in safety early warning measures, the order of implementation is to prioritize eliminating environmental risks, then intervene in the human body's condition, and finally activate ultimate protection. After each intervention, the risk mitigation situation is assessed in real time, and dynamic decisions are made on whether to upgrade the next measure.
[0126] This application provides a method for detecting physiological state. The method includes: first, acquiring the potential signal and environmental parameters from the skin surface of the worker; then, processing the potential signal using a signal inversion algorithm to determine the cell ion concentration, thereby identifying potential physiological problems such as latent fatigue or metabolic imbalance based on this parameter, ensuring worker safety; next, extracting the characteristic frequency of the environmental parameters after determining that the cell ion concentration is within a preset threshold; further, calculating a dynamic balance coefficient based on the cell ion concentration, potential signal, and characteristic frequency; finally, determining the worker's physiological state based on the dynamic balance coefficient. Thus, this method, using electrophysiological signals as the main line and environmental parameters as an auxiliary, achieves deep modeling from the signal layer to the physiological layer, possessing high sensitivity and strong adaptability, enabling early identification of latent fatigue at the cellular level, and improving work safety.
[0127] Figure 2 A flowchart illustrating the physiological state detection method provided in this application embodiment. Figure 2 ,like Figure 2 As shown, in this embodiment... Figure 1Based on the examples, the process of determining whether the cell ion concentration exceeds the preset threshold is described in detail. The method includes:
[0128] S201. Determine whether the cell ion concentration is greater than the preset safety threshold. If not, proceed to S202. If yes, proceed to S203.
[0129] S202. Confirm that the cell ion concentration is within the standard range.
[0130] S203, confirming that the cell ion concentration exceeds the standard.
[0131] It should be noted that after confirming that the cell ion concentration exceeds the standard, it is also necessary to implement safety warning measures for the workers to ensure their physiological health.
[0132] Understandably, by setting safe thresholds for cell ion concentration, dynamic monitoring and tiered response to the electrolyte metabolic status of workers can be achieved. When the cell ion concentration is detected to be within the normal range (not exceeding the standard), it confirms that the human body's metabolism is in balance, and the subsequent assessment process continues. However, once the concentration exceeds the threshold, it is judged as a physiological abnormality, such as signs of dehydration, electrolyte imbalance, or latent fatigue, and a safety warning plan is immediately triggered. This plan uses a three-tiered execution mechanism of equipment adjustment, human compensation, and emergency protection to address potential physiological imbalances and ensure worker safety. This achieves proactive identification and early warning of core physiological parameters.
