Description

Technical Field

[0001] This application relates to the field of power equipment safety monitoring technology, and in particular to a method, device, system and equipment for monitoring water immersion and leakage of power equipment. Background Technology

[0002] With accelerated urbanization and frequent extreme weather events, power infrastructure faces increasingly severe operational challenges. Outdoor power equipment such as distribution transformers, ring main units, and cable distribution boxes pose a high risk of leakage current due to insulation aging, mechanical damage, or severe weather (such as continuous heavy rain and urban flooding) during long-term operation. When water accumulates in the area where the equipment is located, the flooding greatly increases the spread of leakage current, posing a fatal threat of electric shock to pedestrians and inspection personnel, and has become a prominent public safety hazard. Therefore, monitoring water immersion and leakage current in power equipment is of urgent practical significance for protecting people's lives and property and improving the disaster prevention and mitigation capabilities of the power distribution network.

[0003] In related technologies, the monitoring of water immersion and leakage in power equipment mainly relies on the following decentralized solutions: First, manual inspection, where maintenance personnel use voltage detectors to approach power equipment for leakage detection, or go to the site during the flood season to check for water accumulation. Second, remote video monitoring using network cameras installed in low-lying areas, with monitoring center personnel judging the on-site water immersion situation based on experience. Third, monitoring using sensors, such as installing contact water immersion sensors inside enclosures or setting up independent water level gauges near the equipment. However, these solutions are all difficult to achieve rapid and accurate identification of water immersion and leakage conditions in power equipment, and cannot meet the urgent needs of current power grid disaster prevention and mitigation and public safety protection. Summary of the Invention

[0004] This application provides a method, apparatus, system, and equipment for monitoring water immersion and leakage of power equipment, in order to improve the problem that the solutions in related technologies are difficult to achieve rapid and accurate identification of water immersion and leakage status of power equipment.

[0005] In a first aspect, this application provides a method for monitoring water immersion and leakage current in electrical equipment, comprising:

[0006] Obtain electrical monitoring data of the grounding wires of the power equipment, as well as water level monitoring data of the area where the power equipment is located;

[0007] Determine whether a leakage event has occurred based on electrical monitoring data;

[0008] The water level monitoring data is used to determine whether a water flooding event has occurred. When the water level monitoring data exceeds the preset water level threshold, a visual verification operation is triggered, and the result of the visual verification operation is used to determine whether a water flooding event has occurred.

[0009] Based on the combination of the judgment results of water immersion events and the judgment results of leakage events, different alarm levels are determined, and alarm responses corresponding to the alarm levels are executed.

[0010] In one possible implementation, the electrical monitoring data is the current value through the grounding wire; determining whether a leakage event has occurred based on the electrical monitoring data includes: if the current value remains zero or below a preset non-inductive threshold, it is determined that no leakage event has occurred in the power equipment; if the current value suddenly increases from zero or low and exceeds a preset leakage determination threshold, it is determined that a leakage event has occurred in the power equipment.

[0011] In one possible implementation, triggering the visual verification operation includes: activating an image acquisition device in the area where the power equipment is located to acquire images of the installation area of ​​the water level monitoring component, thereby obtaining a water level monitoring image; and performing analysis and processing based on the water level monitoring image to obtain the result of the visual verification operation.

[0013] In one possible implementation, the method for monitoring water immersion and leakage of electrical equipment further includes a communication control step: in response to determining that a leakage event has occurred and / or determining that a water immersion event has occurred, switching the communication function from a dormant state to an active state; based on the communication function in the active state, establishing a communication connection with a remote monitoring platform, and sending corresponding event alarm information to the remote monitoring platform.

[0014] In one possible implementation, different alarm levels are determined based on the combination of the determination results of a water immersion event and a leakage current event, including: determining a first alarm level when only a water immersion event is determined; determining a second alarm level when only a leakage current event is determined; and determining a third alarm level when both a water immersion event and a leakage current event are determined. Correspondingly, an alarm response corresponding to the alarm level is executed, including: for the first alarm level, executing a first local alarm action and reporting a first alarm message to the remote monitoring platform, the first alarm message indicating a water immersion event; for the second alarm level, executing a first local alarm action and reporting a second alarm message to the remote monitoring platform, the second alarm message indicating a leakage current event; and for the third alarm level, executing a second local alarm action and reporting a third alarm message to the remote monitoring platform, the third alarm message indicating that both a water immersion event and a leakage current event have occurred simultaneously. The second local alarm action differs from the first local alarm action in alarm intensity, mode, or content.

[0015] In one possible implementation, the method for monitoring water immersion and leakage of electrical equipment further includes a platform interaction step: in response to receiving an instruction from a remote monitoring platform, performing at least one of the following operations: reporting current electrical monitoring data and / or water level monitoring data to the remote monitoring platform; and adjusting preset threshold parameters according to the instruction, the threshold parameters including a water level threshold and / or a leakage determination threshold.

[0016] Secondly, this application provides a water immersion and leakage monitoring device for electrical equipment, comprising:

[0017] The acquisition module is used to acquire electrical monitoring data of the grounding wire of the power equipment, as well as water level monitoring data of the area where the power equipment is located;

[0018] The leakage event detection module is used to determine whether a leakage event has occurred based on electrical monitoring data.

[0019] The flooding event determination module is used to determine flooding events based on water level monitoring data. When the water level monitoring data exceeds the preset water level threshold, a visual verification operation is triggered, and the result of the visual verification operation is used to determine whether a flooding event has occurred.

[0020] The alarm processing module is used to determine different alarm levels based on the combination of the judgment results of water immersion events and the judgment results of leakage events, and to execute alarm responses corresponding to the alarm levels.

[0021] Thirdly, this application provides a water immersion and leakage monitoring system for electrical equipment, including a field monitoring unit and a remote monitoring platform; the field monitoring unit includes:

[0022] An electrical monitoring component, connected to the grounding wire of the power equipment, is used to collect electrical monitoring data from the grounding wire;

[0023] Water level monitoring components are used to collect water level monitoring data in the area where power equipment is located;

[0024] Image acquisition device;

[0025] Local alarm device;

[0026] Communication module; and

[0027] The processing components are respectively connected to the electrical monitoring components, water level monitoring components, image acquisition devices, local alarm devices, and communication modules;

[0028] The processing component is configured to execute methods as described in any of the first aspects;

[0029] The remote monitoring platform is connected to the communication module and is used to interact with the processing components.

[0030] Fourthly, this application provides an electronic device, including: a processor, and a memory communicatively connected to the processor;

[0033] Fifthly, this application provides a computer-readable storage medium storing computer-executable instructions, which, when executed, are used to implement the method of any one of the first aspects.

[0034] Sixthly, this application provides a computer program product, including a computer program that, when executed, implements the method of any one of the first aspects.

[0035] The water immersion and leakage monitoring method, apparatus, system and equipment provided in this application acquire electrical monitoring data of the grounding wire of the power equipment and water level monitoring data of the area where the power equipment is located; determine whether a leakage event has occurred based on the electrical monitoring data; determine a water immersion event based on the water level monitoring data, wherein when the water level monitoring data exceeds a preset water level threshold, a visual verification operation is triggered, and a water immersion event is determined based on the result of the visual verification operation; and determine different alarm levels based on the combination of the water immersion event determination result and the leakage event determination result, and execute alarm responses corresponding to the alarm levels.

[0036] In this process, by acquiring electrical monitoring data of the grounding wires of power equipment without contact, millisecond-level automatic and accurate identification of leakage events is achieved, effectively reducing the safety risks and time delays caused by manual inspections. By establishing a dual verification mechanism of "water level threshold triggering + visual verification," the technical defects of single water immersion sensors being susceptible to environmental interference and cameras relying on subjective human judgment are effectively overcome, significantly improving the accuracy and reliability of water immersion identification, thereby achieving rapid and accurate identification of water immersion and leakage status of power equipment. In addition, based on the combination of the judgment results of water immersion events and leakage events, different alarm levels are determined, and alarm responses corresponding to the alarm levels are executed, achieving true hierarchical and accurate early warning. This intelligent hierarchical early warning mechanism enables maintenance personnel to quickly take targeted measures based on clear alarm levels, significantly improving emergency response efficiency. It not only effectively ensures the stable operation of power equipment but also reduces public safety risks, thereby better meeting the urgent needs of current power grid disaster prevention, mitigation, and safety protection.

[0043] 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

[0044] 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.

[0045] The terms “first,” “second,” etc., used in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, products, or apparatus.

[0046] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties. Furthermore, the collection, use and processing of the relevant data must comply with relevant laws, regulations and standards, and corresponding operation entry points are provided for users to choose to authorize or refuse.

[0047] In related technologies, when manual inspection is used, leakage detection relies entirely on on-site manual operation. Staff need to use voltage detectors to approach electrical equipment for leakage detection, which is not only inefficient but also prone to electric shock accidents in high-risk scenarios such as flooding, causing casualties. At the same time, large-scale manual inspection also brings high human and material costs. When using video surveillance, cameras installed in low-lying areas rely on the experience of personnel at the monitoring center for remote judgment. However, the installation position, shooting angle, and field of view of the cameras are limited, making it difficult to fully and accurately reflect the flooding situation on site. In addition, the continuous operation of cameras requires a stable power supply and high communication traffic support. If solar and battery power are used, it is difficult to guarantee long-term stable operation, resulting in high overall implementation and maintenance costs. When using water immersion sensors or water level gauges for monitoring, the false alarm rate of a single sensor is high. In emergency situations such as sudden rainstorms, maintenance personnel still need to be dispatched to the site to check the data and make decisions, which not only fails to achieve rapid response but also increases the burden of manual inspection. These distributed technical solutions are inadequate in terms of reliability, real-time performance, and cost. They cannot achieve rapid and accurate identification of water immersion and leakage conditions of power equipment, and thus cannot meet the urgent needs of power grid disaster prevention and mitigation and public safety protection.

[0048] To address the aforementioned issues, this application provides a water immersion and leakage monitoring scheme for power equipment. By real-time acquisition of electrical monitoring data from the grounding wire of the power equipment and water level monitoring data from the area where the equipment is located, an independent sensing path for leakage and water immersion status is established. At the logic control level, leakage events are directly determined based on the electrical monitoring data. For water immersion events, a dual verification mechanism of "water level threshold trigger + visual verification" is employed. Visual verification is triggered only when the water level monitoring data exceeds a preset threshold, significantly reducing the false alarms inherent in single sensors. This enables rapid and accurate identification of water immersion and leakage status in power equipment, while also reducing excessive power consumption and equipment wear caused by prolonged continuous operation of the camera. Furthermore, different alarm levels are determined based on the combination of water immersion and leakage event determination results, and alarm responses corresponding to these levels are executed. Through this highly reliable monitoring mechanism with dual-channel collaboration and tiered response, monitoring accuracy is ensured while optimizing system power consumption through an event-driven operating mode, achieving a complete intelligent monitoring closed loop from data acquisition and status identification to risk-level early warning.

[0049] 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.

[0050] Figure 1 This is a schematic flowchart of a method for monitoring water immersion and leakage current in electrical equipment, provided as an exemplary embodiment of this application. Figure 1 As shown, the method for monitoring water immersion and leakage current in electrical equipment includes the following steps:

[0051] S101. Obtain electrical monitoring data of the grounding wire of the power equipment, as well as water level monitoring data of the area where the power equipment is located.

[0052] For example, a monitoring system is deployed for a distribution transformer area in a certain region. For this distribution transformer, an electrical monitoring component is installed on its grounding wire. This component has high-precision measurement capabilities for electrical parameters such as current and voltage, and can collect electrical monitoring data on the grounding wire in real time, such as leakage current magnitude and voltage fluctuations. This data is then transmitted to the monitoring system's processing component via a wireless communication module. Simultaneously, a water level monitoring component, such as a water level sensor or gauge, is installed at a suitable location in the area where the distribution transformer is located (e.g., a low-lying area prone to water accumulation). This water level monitoring component uses a high-precision pressure-based water level measurement principle to accurately measure the water level at its location. This water level monitoring component is also equipped with a wireless communication module to transmit the real-time collected water level monitoring data to the monitoring system's processing component. The monitoring system's processing component stores and initially processes the received electrical and water level monitoring data, thus providing a data foundation for subsequent analysis and processing.

[0053] S102. Determine whether a leakage event has occurred based on electrical monitoring data.

[0054] For example, after receiving electrical monitoring data from the grounding wire of the distribution transformer, the processing component of the monitoring system analyzes and processes it using a preset leakage current detection algorithm. This algorithm sets a threshold range for the electrical monitoring data based on a large amount of experimental data and industry experience. Once the electrical monitoring data is determined to exceed the preset threshold, it is marked as a leakage current event.

[0055] S103. Determine whether a flooding event has occurred based on water level monitoring data. When the water level monitoring data exceeds a preset water level threshold, a visual verification operation is triggered, and a determination is made as to whether a flooding event has occurred based on the result of the visual verification operation.

[0056] For example, the processing component of the monitoring system continuously receives water level monitoring data reported by water level monitoring components, such as water level sensors, and compares the water level monitoring data with a preset water level threshold, such as 30 cm. When the water level monitoring data exceeds 30 cm, a visual verification operation is immediately triggered; conversely, if the water level monitoring data does not exceed 30 cm, it is determined that no flooding event has occurred and the visual verification operation is not triggered.

[0057] The visual verification operation refers to an intelligent operation in which the processing component automatically activates the image acquisition device to perform secondary verification of the water level monitoring data when the water level monitoring data exceeds a preset water level threshold. This operation acquires visual information of the area where the water level monitoring component is located by the image acquisition device, and analyzes and processes the acquired visual information to determine whether a flooding event has occurred.

[0058] It should be noted that a water level threshold of 30 cm is merely an example. In practical applications, this water level threshold can be flexibly configured and adjusted based on the specific type of power equipment being monitored (such as transformers or ring main units), the elevation of the installation location, historical flooding water level data, and local weather warning levels. For example, for equipment installed in lower-lying areas, the threshold can be set to a lower value (such as 15 cm or 20 cm) to achieve earlier warnings; for equipment installed in higher locations or with good drainage, a higher threshold (such as 50 cm) can be used. The specific value of the water level threshold is not limited here.

[0059] S104. Based on the combination of the judgment results of water immersion event and leakage event, determine different alarm levels and execute the alarm response corresponding to the alarm level.

[0060] Specifically, after independently determining whether a water immersion event or a leakage event has occurred, the processing component will perform a combined analysis of the two Boolean logic results, "whether water immersion has occurred" and "whether leakage has occurred". Based on different combinations, the results will be mapped to multiple preset, discrete alarm levels, and each alarm level will correspond to a set of predefined, complete alarm response strategies.

[0061] For example, the processing component may define several different risk scenarios and assign a specific level identifier to each scenario. Then, it automatically executes an alarm response matching that level identifier. This alarm response is typically a composite action, encompassing both local alerting and remote reporting: for example, at the power equipment site, it activates local alarm devices such as audible and visual alarms, executing a specific alarm mode (such as different sound frequencies, flashing rhythms, or voice content) that matches the risk level; simultaneously, it sends a structured alarm message containing key information such as event type, risk level, time, and location to the remote monitoring platform, so that the operations and maintenance center can record, display, and initiate the corresponding handling procedures.

[0062] The water immersion and leakage monitoring method for power equipment provided in this application acquires electrical monitoring data of the grounding wire of the power equipment without contact, achieving millisecond-level automatic and accurate identification of leakage events. This effectively reduces the safety risks and time delays caused by manual inspections. By establishing a dual verification mechanism of "water level threshold triggering + visual verification," it effectively overcomes the technical defects of single water immersion sensors being susceptible to environmental interference and cameras relying on subjective human judgment, significantly improving the accuracy and reliability of water immersion identification, thereby achieving rapid and accurate identification of water immersion and leakage status of power equipment. In addition, based on the combination of the judgment results of water immersion events and leakage events, different alarm levels are determined, and alarm responses corresponding to the alarm levels are executed, achieving true hierarchical and accurate early warning. This intelligent hierarchical early warning mechanism enables maintenance personnel to quickly take targeted measures based on clear alarm levels, significantly improving emergency response efficiency. It not only effectively ensures the stable operation of power equipment but also reduces public safety risks, thus better meeting the urgent needs of current power grid disaster prevention, mitigation, and safety protection.

[0063] In some embodiments, the electrical monitoring data is the current value through the grounding wire; determining whether a leakage event has occurred based on the electrical monitoring data includes: if the current value is continuously zero or lower than a preset non-inductive threshold, it is determined that no leakage event has occurred in the power equipment; if the current value suddenly increases from zero or low value and exceeds a preset leakage determination threshold, it is determined that a leakage event has occurred in the power equipment.

[0064] For example, the electrical monitoring component is a current transformer. Accordingly, the current value flowing through the grounding wire of the power equipment is collected in real time as electrical monitoring data via a current transformer connected in series. Correspondingly, the processing component performs real-time monitoring and logical judgment on the continuously collected current value. If the current value remains below zero or a non-inductive threshold (e.g., 0.5 amps), it indicates that there is no abnormal current in the grounding wire, and the power equipment is determined to be operating normally without a leakage event. If the current value suddenly and continuously increases from a state close to zero or below the non-inductive threshold, and the increased current value exceeds a preset leakage judgment threshold (e.g., 5 amps), it indicates that the power equipment may have malfunctioned, and a dangerous current is leaking to the ground. In this case, a leakage event is immediately determined.

[0065] It should be noted that the non-inductive threshold of 0.5 amps and the leakage current detection threshold of 5 amps are merely examples. In actual deployments, the non-inductive threshold can be calibrated and set according to the electromagnetic noise level of the site, sensor accuracy, and anti-interference requirements; the leakage current detection threshold can be dynamically configured and adjusted according to the rated parameters, insulation class, safety specifications, and operating conditions of the monitored electrical equipment (such as lower thresholds required in humid environments). The specific values ​​of the non-inductive threshold and the leakage current detection threshold are not limited here.

[0066] It should also be noted that this current transformer is not only used to collect current data from the grounding wire, but it can also function as an energy harvesting unit. When a power device experiences a leakage current, the leakage current generated in the grounding wire flows through the current transformer. Based on the principle of electromagnetic induction, this current induces sufficient electrical energy on the secondary side of the current transformer. This induced electrical energy can be directly used to power circuits such as communication modules, or at least used to generate a wake-up signal to activate the entire monitoring system from its dormant state, thereby achieving passive wake-up and passive monitoring.

[0067] In some embodiments, triggering the visual verification operation includes: activating an image acquisition device in the area where the power equipment is located to acquire images of the installation area of ​​the water level monitoring component, thereby obtaining a water level monitoring image; and performing analysis and processing based on the water level monitoring image to obtain the result of the visual verification operation.

[0068] For example, when the water level monitoring data exceeds a preset water level threshold (e.g., 3 cm), the processing component immediately triggers a visual verification operation. Specifically, the processing component sends a start command to the image acquisition device (e.g., a waterproof camera) deployed on-site. This image acquisition device typically employs a low-power design, with its probe facing downwards during installation, and its viewing angle is precisely adjusted to ensure complete coverage of the installation area of ​​the water level monitoring component (e.g., a pole-mounted water level gauge with a clearly defined scale) and surrounding areas where water may accumulate. After activation, the image acquisition device immediately acquires one or more images of the target area, obtaining water level monitoring images. Correspondingly, the processing component performs intelligent image analysis on the acquired water level monitoring images, automatically parsing the water level status information contained in the images through built-in image processing algorithms, and generating the results of the visual verification operation accordingly.

[0069] This application embodiment achieves high accuracy and low power consumption in water immersion determination through a dual verification mechanism of "water level threshold triggering + visual verification". It not only effectively overcomes the defect of a single sensor being susceptible to environmental interference and false alarms, but also significantly improves the accuracy of identification. In addition, by starting image acquisition and analysis on demand, it effectively reduces the high energy consumption of continuous operation of the image acquisition device, providing a feasible technical path for long-term reliable outdoor monitoring.

[0070] In some embodiments, the analysis and processing of water level monitoring images to obtain the results of visual verification operations includes: performing image preprocessing operations on the water level monitoring images to obtain preprocessed images, wherein the image preprocessing operations include ambient light compensation processing; extracting image features related to water level based on the preprocessed images; and outputting the results of visual verification operations to indicate whether the water immersion status has been confirmed based on the image features.

[0071] For example, image preprocessing is performed on the water level monitoring image. The core of this preprocessing is ambient light compensation to eliminate the impact of poor lighting conditions such as rain, dusk, or night on image quality, thereby ensuring the visibility of water level features. Next, water level-related image features are extracted from the preprocessed image, including visual information such as the scale lines on the water level gauge, reflective edges of the liquid surface, or the submerged boundary of the equipment base. Further, the extracted image features are analyzed and judged. For example, the feature information (such as the scale value corresponding to the identified liquid surface position) is compared with a preset alarm water level threshold. If the features indicate that the water level has reached or exceeded the alarm water level threshold, a "water immersion confirmed" verification result is output; otherwise, a "water immersion denied" verification result is output. This result is directly used to ultimately determine whether a water immersion event has occurred.

[0072] It should be noted that image preprocessing operations for water level monitoring images are not limited to ambient light compensation. In practice, depending on the site environment and the characteristics of the image acquisition device, image preprocessing operations may also include, but are not limited to: image denoising (such as filtering out noise caused by rain, snow, flying insects, etc.), geometric distortion correction (correcting image distortion caused by lens perspective), image enhancement (increasing contrast or sharpness to highlight key details), and region of interest (ROI) cropping (focusing on key image areas containing water level monitoring components to improve processing efficiency), among other operations. These preprocessing steps are designed to work together to optimize the image quality of water level monitoring images, thereby laying a more reliable foundation for subsequent feature extraction and accurate determination.

[0073] The image analysis and processing workflow provided in this application significantly improves the accuracy and environmental adaptability of water immersion verification by performing ambient lighting compensation and water level feature extraction. The ambient lighting compensation operation effectively overcomes image quality fluctuations caused by changes in lighting conditions, ensuring the stability of analysis across different time periods and weather conditions. Feature extraction focuses on identifying key visual information such as water level gauge readings and liquid surface boundaries, providing objective and quantitative evidence for water immersion determination. This workflow significantly enhances adaptability to complex on-site environments, thereby comprehensively improving the reliability of water immersion event determination.

[0074] In some embodiments, the method for monitoring water immersion and leakage of electrical equipment further includes a communication control step: in response to determining that a leakage event has occurred and / or determining that a water immersion event has occurred, switching the communication function from a dormant state to an active state; based on the communication function in the active state, establishing a communication connection with a remote monitoring platform, and sending corresponding event alarm information to the remote monitoring platform.

[0075] For example, when the processing component of the monitoring system determines that a leakage event has occurred based on the acquired electrical monitoring data, and / or ultimately determines that a water immersion event has occurred based on the water level monitoring data and the results of the visual verification operation, the processing component will automatically execute the following communication control steps: 1) Wake up the communication module: The processing component generates a control command to switch the communication module from a low-power sleep state to a full-function working state. This "event-driven" wake-up mechanism ensures that the communication module is in an extremely low-power state during most idle periods when no events occur, thereby significantly reducing the overall energy consumption of the monitoring system, especially suitable for self-powered scenarios relying on "solar energy + batteries". 2) After the communication module is woken up, it automatically establishes a communication connection with the remote monitoring platform. The communication connection method includes, but is not limited to, wireless networks such as 4G / 5G and NB-IoT. 3) Generate corresponding event alarm information and send it to the remote monitoring platform. The event alarm information includes at least the event type (water immersion or leakage or both), event level, occurrence time, device location identifier, and necessary data summary (such as leakage current value, water level value, or a confirmed snapshot of the visual verification result).

[0076] This embodiment of the application switches the communication function from sleep mode to active mode only when a leakage or water immersion event is confirmed. This ensures that the system maintains extremely low static power consumption during periods without events, significantly reducing overall energy consumption. This allows outdoor equipment relying on limited energy sources such as solar power and batteries to achieve long-term stable operation, effectively improving the high energy consumption and power supply problems of traditional continuous online monitoring solutions. Secondly, it ensures the effective utilization of communication resources, reducing meaningless data transmission and thus lowering operating costs (such as data charges). Furthermore, event-triggered instant communication guarantees the real-time and targeted nature of alarm information reporting, enabling the remote monitoring platform to receive accurate risk event reports promptly. This provides timely and reliable data for scheduling maintenance resources and implementing remote control, significantly improving emergency response efficiency and security capabilities.

[0077] In some embodiments, different alarm levels are determined based on the combination of the determination results of a water immersion event and a leakage current event, including: when only a water immersion event is determined, it is determined to be a first alarm level; when only a leakage current event is determined, it is determined to be a second alarm level; when both a water immersion event and a leakage current event are determined, it is determined to be a third alarm level. Correspondingly, an alarm response corresponding to the alarm level is executed, including: for the first alarm level, executing a first local alarm action and reporting a first alarm message to the remote monitoring platform, the first alarm message indicating that a water immersion event has occurred; for the second alarm level, executing a first local alarm action and reporting a second alarm message to the remote monitoring platform, the second alarm message indicating that a leakage current event has occurred; for the third alarm level, executing a second local alarm action and reporting a third alarm message to the remote monitoring platform, the third alarm message indicating that both a water immersion event and a leakage current event have occurred simultaneously; wherein, the second local alarm action differs from the first local alarm action in alarm intensity, mode, or content.

[0078] For example, if only a water immersion event is determined to have occurred (e.g., water level monitoring data exceeds the water level threshold and visual verification confirms it, but leakage is determined not to have occurred), then the current alarm is determined to be at the first alarm level; if only a leakage event is determined to have occurred (e.g., grounding wire current suddenly increases beyond the leakage determination threshold, but water level monitoring data does not exceed the water level threshold or visual verification does not confirm water immersion), then the current alarm is determined to be at the second alarm level; if both a water immersion event and a leakage event are determined to have occurred, then the current alarm is determined to be at the third alarm level, which represents the highest risk scenario, i.e., the extreme dangerous situation of "water immersion and leakage" superimposed.

[0079] Correspondingly, for the first alarm level, a first local alarm action is executed, such as activating an audible and visual alarm to flash and sound at a specific frequency and volume. Simultaneously, a first alarm message is reported to the remote monitoring platform via the communication module. This first alarm message clearly indicates a water immersion event and may also include information such as water level monitoring data. For the second alarm level, the same first local alarm action is executed to warn nearby personnel, and a second alarm message is reported to the remote monitoring platform. This second alarm message clearly indicates a leakage current event and may also include information such as the leakage current value. For the third alarm level, a second local alarm action is executed, which differs from the first local alarm action in alarm intensity, mode, or content. For example, this might involve increasing the output power and frequency of the audible and visual alarm; and / or activating the voice broadcast function, repeatedly playing warnings such as "Danger of leakage current, do not approach"; simultaneously, a third alarm message is reported to the remote monitoring platform. This third alarm message clearly indicates that both water immersion and leakage current events have occurred simultaneously and is marked as the highest priority to drive the remote monitoring platform to initiate the most urgent emergency response procedures.

[0080] It should be noted that the classification methods, corresponding judgment result combinations, and alarm response content of the above-mentioned first, second, and third alarm levels are merely examples. In other embodiments of this application, the number of alarm levels, their definition methods, and the response strategies corresponding to each level can be configured according to actual needs. For example, alarm levels can be set to two, four, or more; each level can correspond to other logical combinations of water immersion and leakage judgment results (e.g., considering the duration or intensity of the event); local alarm actions can include sound, light, and voice prompts of different intensities, frequencies, and modes, or combinations thereof; remote reporting information can also include different data fields, formats, or priority identifiers, etc.

[0081] In this embodiment, by classifying different alarm levels based on the combination of water immersion and leakage event determination results and executing corresponding alarm responses, it is possible to accurately distinguish between single faults and compound faults, enabling maintenance personnel to quickly identify the problem type and severity; moreover, the differentiated local alarm actions corresponding to different alarm levels can significantly improve emergency response efficiency; in addition, by reporting alarm information to the remote monitoring platform in a timely manner, it is convenient for centralized management and remote dispatch, which helps to comprehensively ensure the safe and stable operation of power equipment.

[0082] Based on the above embodiments, in some embodiments, the method for monitoring water immersion and leakage of electrical equipment further includes a platform interaction step: in response to receiving an instruction from a remote monitoring platform, performing at least one of the following operations: reporting current electrical monitoring data and / or water level monitoring data to the remote monitoring platform; adjusting preset threshold parameters according to the instruction, the threshold parameters including water level threshold and / or leakage determination threshold.

[0083] For example, if the instruction is a data query instruction, the processing component immediately collects or retrieves the current electrical monitoring data (i.e., the real-time grounding current value) and / or the current water level monitoring data (i.e., the real-time water level value) from the cache, packages this real-time data, and reports it to the remote monitoring platform, enabling platform maintenance personnel to proactively obtain the latest on-site status at any time. Correspondingly, if the instruction is a parameter adjustment instruction, the processing component parses the new threshold parameters contained in the parameter adjustment instruction and updates the local preset values ​​using the new threshold parameters. These threshold parameters include, but are not limited to, water level thresholds and / or leakage current detection thresholds. For instance, before the rainy season, the remote monitoring platform can remotely lower the water level alarm threshold from 30 cm to 20 cm to achieve earlier warnings; based on the insulation aging of power equipment or seasonal changes, the platform can remotely adjust the leakage current detection threshold from 5 amps to 3 amps to improve monitoring sensitivity.

[0084] In this embodiment, the interaction mechanism significantly enhances the proactive management capabilities and adaptability of the monitoring system, expanding the function of the remote monitoring platform from the traditional passive reception of alarms to proactively initiating equipment status queries and acquiring real-time field data to support decision-making. Furthermore, the remote monitoring platform can dynamically and accurately adjust core monitoring strategies (such as water level and leakage current thresholds) based on the operating environment of the power equipment (e.g., seasonal weather changes, geographical and hydrological conditions) or the equipment's own condition (e.g., insulation aging trends, service life), achieving adaptive optimization of monitoring sensitivity. The entire process does not require maintenance personnel to be physically present on-site, effectively reducing the risks and costs associated with manual inspections and significantly improving the speed of maintenance response and the flexibility of strategy adjustments. This effectively promotes the development of the entire monitoring system towards intelligent and refined management.

[0085] Figure 2 Another schematic flowchart illustrating a method for monitoring water immersion and leakage current in electrical equipment, provided as an exemplary embodiment of this application. (See attached diagram.) Figure 2 As shown, the method for monitoring water immersion and leakage current in electrical equipment includes the following steps:

[0086] S201. Obtain electrical monitoring data of the grounding wire of the power equipment, as well as water level monitoring data of the area where the power equipment is located.

[0087] S202. Determine whether a leakage event has occurred based on electrical monitoring data, and obtain the determination result of the leakage event.

[0088] For example, if the current value remains at zero or below the preset non-inductive threshold, it is determined that no leakage event has occurred in the power equipment; if the current value suddenly increases from zero or low and exceeds the preset leakage determination threshold, it is determined that a leakage event has occurred in the power equipment.

[0089] S203. Determine whether the water level monitoring data exceeds the preset water level threshold.

[0090] If so, execute S204;

[0091] If not, proceed to S208.

[0092] S204. Start the image acquisition device in the area where the power equipment is located to acquire images of the installation area of ​​the water level monitoring component and obtain water level monitoring images.

[0093] S205. Perform image preprocessing on the water level monitoring image to obtain the preprocessed image. The image preprocessing includes ambient light compensation processing.

[0094] S206. Based on the preprocessed image, extract image features related to water level.

[0095] S207. Based on image features, determine whether a water immersion event has occurred and obtain the determination result of the water immersion event.

[0096] S208. Based on the combination of the judgment results of water immersion event and leakage event, determine different alarm levels and execute the alarm response corresponding to the alarm level.

[0097] In summary, this application has at least the following advantages:

[0098] First, by adopting a passive monitoring method based on electromagnetic induction, the monitoring system can quickly and accurately identify the leakage current of the grounding wire of power equipment. Moreover, the occurrence of a leakage event can directly use the energy of the leakage current to wake up the system, realizing true "event-driven" and "zero static power consumption". This not only ensures millisecond-level response speed, but also effectively reduces the necessity for maintenance personnel to conduct on-site voltage testing in high-risk environments such as flooding. While ensuring personal safety, it also significantly saves manpower and material costs.

[0099] Second, the accuracy and reliability of water immersion identification are significantly improved through a dual verification mechanism of "physical perception + visual intelligence". Specifically, a physical threshold judgment is made by a water level sensor. Only when the water level monitoring data exceeds the preset water level threshold is a high-power vision system, such as an image acquisition device, activated for image verification. This "on-demand activation" strategy effectively overcomes the inherent defect of a single water immersion sensor being susceptible to environmental interference (such as condensation and splashing water) leading to a high false alarm rate. Furthermore, intelligent image analysis (such as environmental compensation and feature extraction) provides objective and accurate secondary verification, thereby achieving autonomous and accurate identification and location of water immersion events without the need for personnel to arrive at the scene to make a reliable judgment.

[0100] Third, by combining the status of the leakage and water immersion channels, and determining whether the incident is a combination of leakage, water immersion, or both, the system can provide back-end staff with more accurate information about the scene than a single alarm, which is rich in context. This helps repair personnel assess the risk level, predict the scope of the fault, and formulate the optimal handling strategy.

[0101] Fourth, by combining the results of water immersion incident assessment with those of leakage incident assessment, different alarm levels are automatically matched and differentiated response actions are executed. This ensures that the warning intensity issued to passersby and repair personnel is strictly matched to the risks they face, thereby minimizing the electric shock accidents that may be caused by insufficient or confused alarms, and thus comprehensively improving the level of public safety protection.

[0111] In one possible implementation, the alarm processing module 34 may be specifically used to: switch the communication function from a sleep state to a working state in response to determining that a leakage event has occurred and / or determining that a water immersion event has occurred; establish a communication connection with the remote monitoring platform based on the communication function in the working state, and send the corresponding event alarm information to the remote monitoring platform.

[0112] In one possible implementation, the alarm processing module 34 can also be used to: determine a first alarm level when only a water immersion event is determined; determine a second alarm level when only a leakage event is determined; and determine a third alarm level when both a water immersion event and a leakage event are determined. Correspondingly, it executes an alarm response corresponding to the alarm level, including: for the first alarm level, executing a first local alarm action and reporting a first alarm message to the remote monitoring platform, the first alarm message indicating a water immersion event; for the second alarm level, executing a first local alarm action and reporting a second alarm message to the remote monitoring platform, the second alarm message indicating a leakage event; and for the third alarm level, executing a second local alarm action and reporting a third alarm message to the remote monitoring platform, the third alarm message indicating that both a water immersion event and a leakage event have occurred simultaneously. The second local alarm action differs from the first local alarm action in alarm intensity, mode, or content.

[0113] In one possible implementation, the alarm processing module 34 may also be used to: in response to receiving an instruction from the remote monitoring platform, perform at least one of the following operations: report the current electrical monitoring data and / or water level monitoring data to the remote monitoring platform; and adjust preset threshold parameters according to the instruction, the threshold parameters including water level threshold and / or leakage current determination threshold.
