[0002] With the development of meteorological monitoring and lightning early warning technologies, lightning detection equipment is gradually evolving from simple event recording towards intelligence and low power consumption, and its application in unattended field scenarios is becoming increasingly widespread. Low-power management of lightning detection equipment is a highly complex task. To ensure the long-term reliable operation of the equipment, the management system needs to possess accurate event perception, rapid wake-up decision-making, and adaptive energy consumption control capabilities. During operation, due to environmental electromagnetic interference, the suddenness of lightning events, and the diversity of environmental risk factors, existing lightning detection equipment, limited by low power consumption requirements, can typically only maintain very limited sensing capabilities in its dormant state.

[0003] In related technologies, when lightning detection equipment needs to conserve energy by entering a dormant state in deep-sea environments, it often uses lightning signals to determine thresholds and wake up the equipment. However, when the lightning signal is weak but the environmental risk is high and lightning is about to occur, the monitoring equipment cannot be woken up in time to monitor, thus missing the lightning signal.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] With the development of meteorological monitoring and lightning early warning technologies, lightning detection equipment has gradually evolved from simple event recording towards intelligence and low power consumption, and its application in extreme environments such as deep-sea environments is becoming increasingly widespread. Low-power management of lightning detection equipment is a highly complex task. To ensure the long-term reliable operation of the equipment, the management system needs to possess accurate event perception, rapid wake-up decision-making, and adaptive energy consumption control capabilities. During operation, due to environmental electromagnetic interference, the suddenness of lightning events, and the diversity of environmental risk factors, existing lightning detection equipment, in its dormant state, is limited by low-power requirements and can typically only maintain very limited sensing capabilities. In related technologies, lightning detection equipment in deep-sea environments needs to save energy through a dormant state, but often relies on lightning signals for threshold judgment to wake up the equipment. However, when the lightning signal is weak but the environmental risk is high, indicating an impending lightning strike, the monitoring equipment cannot be woken up in time, thus missing the lightning signal.

[0027] Therefore, how to develop a method for waking up lightning detection equipment from hibernation while ensuring low power consumption and accurate multi-factor judgment has become a key issue that urgently needs to be addressed in the field of unattended meteorological monitoring.

[0028] One of the core concepts of this invention is the acquisition of electromagnetic information through an electromagnetic signal sensor and environmental information through an environmental parameter sensor. The electromagnetic information is used to determine the credibility of lightning events, while the environmental information is used to determine the credibility of environmental risk events. The credibility of lightning events directly reflects the instantaneous probability of lightning occurrence, while the credibility of environmental risk events reflects the cumulative degree and evolution trend of thunderstorm precursors, such as sudden changes in air humidity. There is a close physical correlation between lightning events and environmental risk events: a sustained increase in environmental risk often foreshadows an impending lightning event, and the occurrence of a lightning event, in turn, exacerbates changes in environmental risk parameters. Based on this, embodiments of the present invention determine the credibility of lightning events based on electromagnetic information using electromagnetic signal sensors, and determine the credibility of environmental risk events based on environmental information; a wake-up strategy is determined based on the credibility of lightning events and environmental risk events, and the wake-up strategy is used to indicate the target object that needs to be woken up; by waking up the target object according to the wake-up strategy using electromagnetic signal sensors, the problem in the prior art of not being able to wake up the equipment in time when the lightning signal is weak but the environmental risk is high and lightning is about to occur, due to the inability to sense only a single lightning signal, can be avoided, thus accurately determining the wake-up strategy; and the appropriate target object is woken up according to the accurate wake-up strategy. Compared with the prior art based on a single lightning signal threshold judgment, embodiments of the present invention achieve precise wake-up control of each module in the lightning detection equipment based on a comprehensive judgment of lightning events and environmental risk events. In the dormant state, when the lightning signal is weak but the environmental risk is high and lightning is about to occur, the corresponding module can be woken up in time, ensuring the energy-saving effect of the equipment while achieving accurate monitoring of lightning events.

[0029] Figure 1 This is a flowchart illustrating the steps of a sleep / wake-up method for a lightning detection device provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the sleep-wake method of the lightning detection device in this embodiment of the invention may include the following steps: Step 101: Collect electromagnetic information through the electromagnetic signal sensor and collect environmental information through the environmental parameter sensor; In this embodiment of the invention, the lightning detection device includes a data acquisition module, a data processing module, a power supply module, and a communication module. The data acquisition module includes an electromagnetic signal sensor, an environmental parameter sensor, and other sensors. The data processing module, communication module, and other sensors are in a sleep state when they do not receive a wake-up signal. The lightning detection device may also include other modules that are also in a sleep state when not woken up. The electromagnetic signal sensor can characterize a sensor used to sense electromagnetic signals such as changes in the electromagnetic field in space and lightning radiation pulses. It has low power consumption and is suitable for continuous operation in a sleep state. Electromagnetic information can characterize the lightning signal data collected by the electromagnetic signal sensor, including electric field strength, magnetic field strength, and electromagnetic wave spectrum characteristics. The environmental parameter sensor can characterize a sensor used to sense physical quantities in the surrounding environment. Environmental information can characterize the data collected by the environmental parameter sensor. Environmental information is related to lightning signals. Typically, in deep-sea environments, lightning events are accompanied by environmental risk events. Therefore, environmental risk events can indicate that a lightning event may be imminent.

[0030] By using electromagnetic signal sensors and environmental parameter sensors to continuously collect data in parallel while the device is in sleep mode, this invention enables lightning detection equipment to simultaneously obtain electromagnetic signals reflecting instantaneous lightning events and environmental physical quantities reflecting thunderstorm precursors without waking up the data processing module and communication module.

[0031] Step 102: The credibility of the lightning event is determined based on the electromagnetic information by the electromagnetic signal sensor, and the credibility of the environmental risk event is determined based on the environmental information; the credibility of the lightning event is used to characterize the probability of a lightning event occurring; the credibility of the environmental risk event is used to characterize the probability of an environmental risk event occurring. In this embodiment of the invention, a lightning event can characterize the electromagnetic radiation phenomenon generated by instantaneous discharge between clouds and the ground or within clouds, such as cloud-to-ground lightning, intra-cloud lightning, and inter-cloud lightning. The credibility of a lightning event can characterize the probability of a lightning event that is about to occur or is currently occurring, calculated based on current electromagnetic information. An environmental risk event can characterize severe meteorological conditions that precede thunderstorms, such as a rapid increase in humidity or a significant increase in salt spray concentration in the air. The credibility of an environmental risk event can characterize the probability of severe meteorological conditions that precede thunderstorms, calculated based on current environmental information. For example, when the absolute value of the ground electric field strength exceeds a certain preset threshold and continues to rise, the credibility of the lightning event increases.

[0032] In some examples, there is a physical correlation between lightning events and environmental risk events: During the formation and development of thunderstorm clouds, charge accumulates, leading to a gradual increase in the electric field strength between the cloud layer and the ground. This is accompanied by water vapor transport and sudden temperature changes. The continuous rise or drastic fluctuation of these environmental parameters are precursory signals of impending lightning. When a lightning event actually occurs, the intense discharge process instantly alters the spatial electric field distribution and generates electromagnetic radiation, while also causing sudden changes in local humidity and air pressure. Therefore, environmental risk events can be considered precursory indicators of impending lightning events, while lightning events are the concentrated release of accumulated environmental risks after reaching a critical threshold. Relying solely on the reliability of lightning events is prone to missed reports due to signal attenuation, distance, or electromagnetic interference; while relying solely on the reliability of environmental risk events makes it difficult to determine the precise time and intensity of lightning occurrence. Therefore, the reliability of environmental risk events can serve as a basis for predicting the probability of lightning events. When the lightning signal is weak or the distance is far, a higher reliability of environmental risk events can indicate that lightning is imminent.

[0033] By calculating the credibility of lightning events and the credibility of environmental risk events separately, this embodiment of the invention transforms the original electromagnetic signals and environmental parameters into quantifiable probability indicators. When the lightning signal is weak due to distance or attenuation, the credibility of environmental risk may still be high, thereby making up for the inherent defects of judging a single lightning threshold.

[0034] Step 103: Determine a wake-up strategy based on the credibility of the lightning event and the credibility of the environmental risk event; the wake-up strategy is used to indicate the target object that needs to be woken up. In this embodiment of the invention, the wake-up strategy can be a pre-defined set of modules that need to be woken up from a hibernation state. The target objects may include one or more of the following: a data processing module, a communication module, and other sensors.

[0035] In some examples, the wake-up strategy can also be prioritized: when the confidence level of environmental risk events continues to rise but the confidence level of lightning events remains low, the wake-up frequency can be gradually increased or more sensors can be woken up for confirmation, in order to avoid missed or false alarms caused by hard switching of a single threshold.

[0036] By jointly determining the wake-up strategy based on the credibility of lightning events and environmental risk events, this embodiment of the invention achieves precise wake-up control for different target objects. This allows for the wake-up of necessary corresponding modules based on different lightning events and environmental risks, avoiding frequent false wake-ups or missed reports of critical events caused by a single threshold judgment.

[0037] Step 104: The target object is woken up by the electromagnetic signal sensor according to the wake-up strategy.

[0038] In this embodiment of the invention, an electromagnetic signal sensor can output control signals, such as interrupt signals, level signals, or communication commands, according to a wake-up strategy, to switch the target object from a dormant state to an active state. The target object can be a data processing module, a communication module, or other sensors.

[0039] In some examples, the electromagnetic signal sensor can integrate a low-power microcontroller capable of calculating the confidence level of lightning events and environmental risk events in real time, and determining whether to wake up other modules based on a preset wake-up strategy. When wake-up is required, the electromagnetic signal sensor can output a wake-up pulse through a hardware pin to send a wake-up command.

[0040] By utilizing electromagnetic signal sensors that operate continuously at low power to perform wake-up operations, the device maintains an extremely low power consumption state while achieving comprehensive judgment and precise wake-up, thus meeting the energy-saving requirements for long-term reliable operation in deep-sea scenarios.

[0041] This invention provides a method for waking up a lightning detection device from hibernation. It collects electromagnetic information using an electromagnetic signal sensor and environmental information using an environmental parameter sensor. The electromagnetic signal sensor determines the credibility of a lightning event based on the electromagnetic information, and the environmental parameter sensor determines the credibility of an environmental risk event based on the environmental information. A wake-up strategy is determined based on the credibility of the lightning event and the environmental risk event, and this strategy indicates the target object that needs to be woken up. The probability of a lightning event is determined by the electromagnetic signal sensor, and the probability of an environmental risk event is determined by the environmental parameter sensor. This achieves precise wake-up control of various modules within the lightning detection device based on a comprehensive judgment of lightning events and environmental risk events. In hibernation mode, when the lightning signal is weak but the environmental risk is high, indicating that lightning is about to occur, the corresponding modules can be woken up in a timely manner, ensuring the energy-saving effect of the device while achieving accurate monitoring of lightning events.

[0042] Figure 2 This is a flowchart illustrating the steps of a sleep / wake-up method for a lightning detection device provided in an embodiment of the present invention, as shown below. Figure 2 As shown, the sleep-wake method of the lightning detection device in this embodiment of the invention may include the following steps: Step 201: Collect electromagnetic information through the electromagnetic signal sensor and collect environmental information through the environmental parameter sensor; In this embodiment of the invention, the lightning detection device includes a data acquisition module, a data processing module, a power supply module, and a communication module. The data acquisition module includes an electromagnetic signal sensor, an environmental parameter sensor, and other sensors. The data processing module, communication module, and other sensors are in a sleep state when no wake-up signal is received. The electromagnetic signal sensor is suitable for continuous operation in the sleep state. The environmental parameter sensors may include humidity sensors, salt spray concentration sensors, temperature sensors, etc., used to acquire environmental data related to thunderstorm precursors.

[0043] Existing technologies are prone to misjudgment in electromagnetic interference environments due to a lack of environmental data; however, this invention can detect risks even when lightning signals are weak by sensing thunderstorm precursors through environmental information, providing a basis for subsequent adaptive judgment.

[0044] Step 202, the electromagnetic information includes: the field strength of the lightning signal, the energy of the main frequency band of the lightning signal, the total energy of the lightning signal, and the pulse slope; the pulse slope represents the ratio of the pulse peak value to the pulse width; obtain the field strength threshold corresponding to the field strength and the pulse threshold corresponding to the pulse slope; In this embodiment of the invention, the field strength of the lightning signal can characterize the peak electric field strength at the detection point where the lightning radiation reaches, with units of V / m, directly reflecting the intensity of the lightning. The energy of the main frequency band of the lightning signal can characterize the energy concentration of the lightning signal near its main frequency component (e.g., 5kHz to 10kHz), used to distinguish lightning from industrial interference (industrial interference usually has a wider spectrum). The total energy of the lightning signal can characterize the total integrated energy of the entire lightning electromagnetic pulse waveform. The pulse slope can characterize the ratio of the pulse peak value to the pulse width, i.e., the steepness of the pulse rise edge. The rise edge of a lightning pulse is usually on the order of microseconds, with a very high slope, while the slope of interference such as electrostatic discharge is relatively small.

[0045] In some embodiments, the following steps may be included prior to step 202: Determine the background electromagnetic noise level in the electromagnetic information; obtain a first noise threshold and a second noise threshold corresponding to the background electromagnetic noise level; when the background electromagnetic noise level is higher than the first noise threshold, increase the field strength threshold; when the background electromagnetic noise level is lower than the second noise threshold, decrease the field strength threshold.

[0046] In this embodiment of the invention, the background electromagnetic noise level can characterize the root mean square value of non-lightning electromagnetic interference that persists in the environment, such as from power lines, radio transmitters, motor commutators, etc. The first noise threshold (e.g., 50 mV / m) can characterize the upper limit of noise that needs to be increased to suppress false alarms, and the second noise threshold (e.g., 10 mV / m) can characterize the lower limit of noise that can be decreased to improve sensitivity.

[0047] By dynamically adjusting the field strength threshold, this invention achieves adaptive sensitivity control under different noise environments. Compared with the existing technology that uses a fixed field strength threshold, it can detect weak lightning signals at greater distances in low-noise environments and effectively suppress frequent false alarms in high-noise environments, thus resolving the contradiction between high sensitivity and low false alarm rate that cannot be achieved with a fixed threshold.

[0048] Step 203: The confidence level of the lightning event is determined by weighted summation of the ratio of the field strength to the field strength threshold, the ratio of the main frequency band energy of the lightning signal to the total energy of the lightning signal, and the ratio of the pulse slope to the pulse slope threshold. In this embodiment of the invention, the confidence level of a lightning event can be characterized by the probability value of a lightning event occurring, calculated based on multi-dimensional electromagnetic features, typically ranging from 0 to 1. The weighted summation formula can be: R light =w1·(E / E th )+w2·(E band / E total )+w3·(S / S th ), where R light The credibility of the lightning event is given by E, where E is the field strength. th E is the dynamic field strength threshold. band Main frequency band energy, E total S is the total energy, S is the pulse slope, S th This is the pulse slope threshold. The weighting coefficients w1, w2, and w3 can be calibrated using historical data or updated adaptively. For example, w1=0.4, w2=0.35, w3=0.25, and the sum of w1, w2, and w3 is 1.

[0049] In this embodiment of the invention, to ensure that the credibility value of the lightning event always falls within the [0,1] interval, so that it can be used as a probability value in subsequent credibility fusion and wake-up decisions, each feature ratio is subjected to upper limit truncation and normalization. For example, when the measured field strength is less than or equal to a preset field strength threshold, E / E th ∈[0,1]; When the measured field strength exceeds the preset field strength threshold, E / E th =1, meaning that the portion exceeding the threshold no longer contributes additional credibility.

[0050] Compared to existing technologies that rely solely on whether the field strength exceeds a fixed threshold to determine lightning, this invention introduces two features: the dominant frequency band energy ratio and the pulse slope. The dominant frequency band energy ratio can eliminate wide-spectrum industrial interference, while the pulse slope can eliminate slow-front electrostatic discharge. Through weighted fusion, even if the field strength is slightly below the threshold, if the dominant frequency band energy is concentrated and the pulse slope is steep, the credibility of the lightning event can still reach a high level, significantly improving the identification accuracy and reducing false alarms.

[0051] Step 204, the environmental information includes: humidity, salt spray concentration and temperature change; obtain the humidity threshold corresponding to the humidity, the salt spray threshold corresponding to the salt spray concentration, and the temperature change threshold corresponding to the temperature change. In this embodiment of the invention, humidity in the environmental information can represent the relative humidity of the air. Humidity typically rises rapidly before a thunderstorm. Salt spray concentration can represent the content of salt particles in the air; in marine environments, increased salt spray concentration enhances air conductivity, which is conducive to lightning strikes. Temperature can represent the ambient temperature; thunderstorms are often accompanied by the convergence of warm and cold air currents, and sudden temperature changes are one of the precursors. Humidity threshold, salt spray threshold, and temperature threshold can be set based on local historical meteorological data. For example, the humidity threshold could be set to 80% RH, the salt spray threshold to 5 mg / m³, and the temperature threshold to a change exceeding 10°C within 24 hours.

[0052] By collecting three environmental parameters, this invention can comprehensively capture multiple physical characteristics of thunderstorm precursors. Compared with existing technologies that completely disregard environmental information, this invention can detect thunderstorm risks in advance through abnormal changes in environmental parameters before the electromagnetic signal of lightning appears or when the signal is extremely weak, thus compensating for the blind spots of single electromagnetic detection in long-distance or weak signal scenarios.

[0053] Step 205: Perform a weighted summation of the ratio of humidity to humidity threshold, the ratio of salt spray concentration to salt spray threshold, and the ratio of temperature change to temperature change threshold to determine the credibility of the environmental risk event; In this embodiment of the invention, the credibility of an environmental risk event can characterize the probability value of a thunderstorm precursor or severe weather event calculated based on environmental parameters, and the value ranges from 0 to 1. The calculation formula can be: R env =v1·(H / H th )+v2·(S salt / S th )+v3·(ΔT / T th ), where R env For the credibility of environmental risk events, H represents the current humidity. th For humidity threshold; S salt S represents the salt spray concentration. th ΔT is the salt spray threshold; ΔT is the temperature change, T th This represents the temperature change threshold. The weighting coefficients v1, v2, and v3 can be adjusted according to different regional characteristics; for example, the salt spray weight can be appropriately increased in coastal areas. The sum of v1, v2, and v3 is 1. In this embodiment of the invention, to ensure that the credibility value of the environmental risk event always falls within the [0,1] interval, so that it can be used as a probability value in subsequent credibility fusion and wake-up decisions, the upper limit truncation and normalization processing is performed on each environmental feature ratio. For example, when the measured humidity is less than or equal to a preset humidity threshold, H / H th ∈[0,1]; When the measured humidity exceeds the preset humidity threshold, H / H th =1, meaning that the portion exceeding the threshold no longer contributes additional environmental risk. Through the above upper limit truncation normalization process, the contribution factors of each environmental feature are constrained within the [0,1] interval, thereby ensuring that the credibility of the environmental risk event obtained after weighted summation is strictly between 0 and 1.

[0054] Compared to existing technologies that ignore environmental risks, this invention integrates multiple environmental parameters into a comprehensive index through weighted summation. When humidity approaches saturation, salt spray concentration increases, and temperature changes drastically simultaneously, the credibility of the environmental risk event significantly increases. Even if the electromagnetic signal sensor does not detect a strong lightning signal at this time, it can still be recognized that a thunderstorm is approaching.

[0055] Step 206: Calculate the weighted sum of the credibility of the lightning event and the credibility of the environmental risk event to determine the overall credibility. In this embodiment of the invention, the overall credibility can characterize the overall trust level after comprehensively considering lightning events and environmental risk events, and is used for final decision-making.

[0056] The calculation formula can be: C = α·R light +β·R env Where C is the overall credibility, α and β are weighting coefficients, and α + β = 1. For example, α can be 0.6 and β can be 0.4, because the credibility of lightning events has higher instantaneous decision-making value, while the credibility of environmental risks serves as an auxiliary reference. Generally speaking, α can be set to be greater than β.

[0057] Compared to existing technologies that only use the reliability of lightning events, this invention introduces environmental risk weights. When lightning signals become unreliable due to distance attenuation or electromagnetic interference, if the environmental risk continues to rise, the overall reliability may still exceed the wake-up threshold, thereby triggering device wake-up.

[0058] Step 207: Determine the wake-up strategy based on the overall credibility. In this embodiment of the invention, the wake-up strategy can characterize a hierarchical scheme for determining which target objects to wake up.

[0059] In some instances, step 207 may include the following sub-steps: Sub-step S11: Obtain a first wake-up threshold and a second wake-up threshold; the first wake-up threshold is greater than the second wake-up threshold; In some examples, the following steps may also be included before sub-step S11: The state of charge, low power threshold, and high power threshold of the power supply module are obtained; when the state of charge is lower than the low power threshold, the first wake-up threshold is increased; when the state of charge is higher than the high power threshold, the second wake-up threshold is decreased.

[0060] In this embodiment of the invention, the state of charge (SBC) of the power supply module can characterize the remaining percentage of power in the battery or solar power system. Low power thresholds (e.g., 20%) and high power thresholds (e.g., 80%) are used to determine the sufficiency of power. When the SBC is below the low power threshold, the device is in a low-power state. In this case, the first-level wake-up threshold should be increased (e.g., from 0.7 to 0.85) to avoid depleting the remaining power by waking up high-power units such as the communication module. When the SBC is above the high power threshold, the power is sufficient, and the second-level wake-up threshold can be decreased (e.g., from 0.4 to 0.3) to increase the probability of capturing weak lightning signals.

[0061] Compared to existing technologies that use a fixed wake-up threshold, this invention achieves a balance between energy efficiency and detection performance by dynamically adjusting the wake-up threshold based on the power supply module's state of charge. When power is sufficient, the device prioritizes sensitive detection, trying not to miss any lightning precursors; when power is scarce, the device prioritizes energy conservation, ensuring power supply for critical functions.

[0062] Sub-step S12: If the overall confidence level is greater than or equal to the first wake-up threshold, then the wake-up strategy is determined to be a level one wake-up strategy. The level one wake-up strategy is used to instruct the other sensors of the data acquisition module, the data processing module, and the communication module to be woken up. In this embodiment of the invention, the first-level wake-up strategy is designed for scenarios with high overall reliability, where lightning is about to occur or has already occurred, requiring all modules to work: waking up other sensors such as omnidirectional electric field meters and high-speed camera modules can collect more detailed data, waking up the data processing module can perform waveform analysis and location calculations, and waking up the communication module can report early warning information.

[0063] In sub-step S13, if the overall confidence level is greater than or equal to the second wake-up threshold and less than the first wake-up threshold, then the wake-up strategy is determined to be a secondary wake-up strategy. The secondary wake-up strategy is used to instruct the other sensors of the data acquisition module to be woken up.

[0064] In this embodiment of the invention, the two-stage wake-up strategy addresses scenarios with moderate overall confidence but not yet urgent. In such cases, only other sensors are woken up for supplementary observations, while the data processing and communication modules remain dormant to conserve energy. For example, when the environmental risk confidence is high but the lightning event confidence is low, other sensors, such as more precise electric field meters, can be woken up first for confirmation. If continuous data indicates that lightning is imminent, the data processing and communication modules are then further woken up. This tiered wake-up avoids the energy waste of directly activating all modules.

[0065] Step 208: The target object is woken up by the electromagnetic signal sensor according to the wake-up strategy.

[0066] In this embodiment of the invention, an electromagnetic signal sensor can output control signals, such as interrupt signals, level signals, or communication commands, according to a wake-up strategy, to switch the target object from a dormant state to an active state. The target object can be a data processing module, a communication module, or other sensors.

[0067] In some examples, the electromagnetic signal sensor can integrate a low-power microcontroller capable of calculating the confidence level of lightning events and environmental risk events in real time, and determining whether to wake up other modules based on a preset wake-up strategy. When wake-up is required, the electromagnetic signal sensor can output a wake-up pulse through a hardware pin to send a wake-up command.

[0068] By utilizing electromagnetic signal sensors that operate continuously at low power to perform wake-up operations, the device maintains an extremely low power consumption state while achieving comprehensive judgment and precise wake-up, thus meeting the energy-saving requirements for long-term reliable operation in deep-sea scenarios.

[0069] This invention provides a method for waking up a lightning detection device from hibernation. Electromagnetic information is collected by an electromagnetic signal sensor, and environmental information is collected by an environmental parameter sensor. The credibility of a lightning event is determined by weighted summation of the ratios of field strength to a field strength threshold, the ratio of the main frequency band energy of the lightning signal to the total energy of the lightning signal, and the ratio of pulse slope to a pulse slope threshold. The credibility of an environmental risk event is determined by weighted summation of the ratios of humidity to a humidity threshold, the ratio of salt spray concentration to a salt spray threshold, and the ratio of temperature to a temperature threshold. The credibility of both the lightning event and the environmental risk event is weighted summation to determine the overall credibility. A first wake-up threshold and a second wake-up threshold are obtained, where the first wake-up threshold is greater than the second wake-up threshold. If the overall credibility is greater than or equal to the first wake-up threshold... If the overall confidence level is greater than or equal to the second wake-up threshold and less than the first wake-up threshold, then the wake-up strategy is determined to be the first-level wake-up strategy, which is used to instruct other sensors, data processing modules, and communication modules of the data acquisition module to be woken up. If the overall confidence level is greater than or equal to the second wake-up threshold and less than the first wake-up threshold, then the wake-up strategy is determined to be the second-level wake-up strategy, which is used to instruct other sensors of the data acquisition module to be woken up. By waking up the target object according to the wake-up strategy through the electromagnetic signal sensor, a multi-level wake-up control is realized, which adaptively adjusts the lightning judgment threshold based on background noise and the wake-up threshold based on power supply status. This avoids the high false alarm rate or missed alarm problem caused by relying solely on a fixed threshold in the sleep state. While ensuring the energy-saving effect of the equipment, it adapts to the lightning detection needs in complex electromagnetic environments and energy-constrained scenarios.
