The control display 4 is responsible for displaying the working status, monitoring results, parameter settings and other information of the device. Through graphics, text or indicator lights, the user can intuitively understand the current status of the device. The control display 4 is electrically connected to the controller 11, and receives data and instructions sent by the controller 11 through communication methods such as data lines or buses.

The control display 4 may use technologies such as liquid crystal display (LCD) or organic light emitting diode display (OLED) to achieve high-definition and low-power display effects. At the same time, in order to adapt to different ambient light conditions, the control display 4 may also have a backlight adjustment function. The control button 5 is a physical component for the user to perform input operations, usually including a power button, a setting button, up and down selection keys, a confirmation key, etc. The user starts / stops the device, enters the setting interface, adjusts parameters, etc. by pressing these buttons.

The controller 11 performs corresponding operations or adjusts the working state of the device according to the received instructions, which is not limited here.

[0050] The leakage monitor also includes: a power supply, which includes: a lithium battery and a power drive board. The power drive board includes a mains input port, a DC output port and a charging output port.

As an ideal power source for portable devices, the lithium battery 12 has the characteristics of high energy density, long cycle life and low self-discharge rate. In the power module, the lithium battery 12 is responsible for providing power to the entire system when the mains power is not available, ensuring that the device can still work normally in a mobile or non-mains power environment. The output end of the lithium battery 12 is directly connected to key components such as the controller 11 (controller 3 unit) to ensure that these components can obtain a stable power supply when needed. The power drive board 13 is the core component of the power module, which is responsible for converting the input mains power into the DC power required by the internal components of the device, and managing the charging process of the lithium battery 12. The power drive board 13 is provided with a mains input port for receiving an external mains power supply.

This design enables the portable low-voltage leakage monitor device to work stably and reliably in various environments, which are not limited here.

[0052] The leakage monitor also includes: a buzzer. The function of the buzzer in the leakage monitor is to send out an alarm signal to remind the user that a leakage event has occurred. When the leakage monitor detects a leakage in the circuit, the buzzer will emit a sharp sound, allowing the user to pay attention immediately and take appropriate measures. The working mechanism of the buzzer is to generate a magnetic field through the current passing through the electromagnet, causing the diaphragm to vibrate and emit a sound. When the leakage monitor detects a leakage, it will transmit a signal to the buzzer through the circuit, causing the current to flow through the electromagnet, generating a magnetic field to cause the diaphragm to vibrate, thereby emitting a sound. This sound is usually sharp and continuous, which can effectively attract people's attention and is not limited here.

[0053] The leakage monitor also includes: a transformer interface, and a plurality of transformer interfaces electrically connected to the controllers are respectively provided on both sides of the portable box, and the leakage detection transformer is electrically connected to the leakage detection chip through the transformer interface. Exemplarily, a plurality of transformer interfaces electrically connected to the controllers 3 are respectively provided on both sides of the portable box 1, and the leakage detection transformer 2 is electrically connected to the leakage detection chip 15 through the transformer interface 8. On both sides of the portable box 1 of the portable low-voltage leakage monitor device, a plurality of transformer interfaces 8 electrically connected to the controller 3 are specially reserved. These interfaces are specially designed for the leakage detection transformer 2, and are used to realize the electrical connection between the transformer and the leakage detection chip 15. The transformer interface 8 adopts a standardized design to ensure matching with the interface of the leakage detection transformer 2, reducing errors and inconveniences during installation. The standardized interface design also helps to achieve interchangeability between transformers of different brands and models, and improve the versatility and flexibility of the equipment. At the same time, the interface design takes into account the needs of rapid disassembly and assembly, and adopts an easy-to-plug structure. The user can easily insert or remove the leakage detection transformer 2 from the interface without using special tools. This design not only improves work efficiency, but also reduces the difficulty and complexity of operation, which is not limited here.

[0054] The leakage monitor also includes: an installation slot, and a plurality of installation slots are arranged inside the portable box, and a plurality of leakage detection transformers can be detachably mounted in the corresponding installation slots. Exemplarily, a plurality of installation slots are arranged inside the portable box 1, and a plurality of leakage detection transformers 2 can be detachably mounted in the corresponding installation slots. The spatial layout of the installation slots is planned to ensure that the required number of leakage detection transformers 2 can be accommodated, and sufficient space is left for maintenance and replacement. Reasonable spatial layout also helps to improve the overall compactness and portability of the equipment. Corresponding fixing devices, such as buckles, slots or screw holes, are designed inside the installation slots to ensure that the leakage detection transformer 2 can be firmly fixed in the slot after installation. This fixing method can effectively prevent the transformer from shaking or falling off during transportation, and is not limited here.

[0055] The leakage monitor also includes: a power interface, and a power interface electrically connected to the power driver board is provided on the rear side of the portable case. Exemplarily, a power interface 7 electrically connected to the power driver board 13 is provided on the rear side of the portable case 1. The power interface 7 is electrically connected to the power driver board 13 through internal electrical connectors (such as wires, pins, etc.). This connection relationship ensures that the external power supply can stably and safely provide power to the power driver board 13, and then power other modules of the portable low-voltage leakage monitor device (such as the controller 11, the leakage detection chip 15, the alarm module 6, etc.), which are not limited here.

[0056] The leakage monitor also includes: a leakage detection transformer, the number of which is 12, which is an open leakage detection transformer. Exemplarily, the number of leakage detection transformers 2 is 12, and specifically an open leakage detection transformer 2. 12 transformers can monitor the leakage of multiple circuits or devices at the same time, greatly improving the efficiency and accuracy of monitoring. At the same time, it also meets the needs of leakage monitoring points in most application scenarios, making the equipment more flexible and convenient in actual use. The leakage detection transformer 2 adopts an open design, which is optimized for convenience in actual installation and maintenance. The open transformer can be installed without disconnecting the circuit, which greatly reduces the power outage time and installation difficulty and improves work efficiency. The working principle of the open leakage detection transformer is: the open leakage detection transformer 2 determines whether there is leakage by detecting the leakage current in the circuit. When the insulation layer in the circuit is damaged or aged, causing current leakage, the transformer can capture this change and pass the signal to the subsequent processing circuit for analysis and judgment. The open-type leakage detection transformer 2 is suitable for leakage monitoring of various low-voltage circuits and equipment. Whether it is household electricity, industrial production lines or commercial facilities, real-time monitoring and early warning of leakage phenomena can be achieved by using this transformer. Since the open-type leakage detection transformer 2 can be installed and used without disconnecting the circuit, it is safer in actual operation. It reduces the safety risks that may be caused by power outage operations, and also reduces the impact on equipment and circuits, which is not restricted here.

[0057] The leakage monitor also includes: a cloud server and an application program. The controller communicates with the cloud server through a communication module, and the application program is connected to the controller through a two-way communication through the cloud server and the communication module. Exemplarily, the cloud server 16 is the data center of the entire system, responsible for storing all real-time data, historical data, and alarm records collected by the leakage detection transformer 2. These data are efficiently processed and analyzed by the server, and can provide users with detailed circuit status reports and leakage risk assessments. Through the cloud server 16, users can access system data through the network anytime and anywhere to achieve remote monitoring. Once an abnormal situation such as leakage is detected, the server will immediately trigger an alarm mechanism, and notify users or relevant personnel through SMS, application program 17 push, etc., to ensure that the problem is handled in a timely manner. The cloud server 16 also undertakes the important task of system upgrade and maintenance. Through the server, developers can easily push new software versions, fix known vulnerabilities, optimize system performance, etc., to ensure that users always use the latest and most stable products. The supporting application program 17 allows users to query the data collected by the leakage detection transformer 2 in real time through mobile devices such as mobile phones, including key indicators such as leakage current, voltage, and temperature. This instant feedback mechanism helps users to understand the circuit status in a timely manner and make corresponding adjustments. Application 17 also provides a historical data query function, and users can query historical data within a specified time period as needed. Through the analysis of historical data, users can have a more comprehensive understanding of the operating status of the circuit and discover potential problems and hidden dangers. When the cloud server 16 detects abnormal conditions such as leakage and triggers an alarm, the application 17 will immediately display the alarm information and remind the user through various methods such as sound and vibration. Users can view detailed alarm records to understand the specific reasons for the alarm and handling suggestions. Through application 17, users can also remotely manage and control the portable box 1 and the leakage detection transformer 2 inside it. For example, users can remotely start or stop detection tasks, adjust detection parameters, etc., to achieve flexible control of the equipment, which is not limited here.

Once a leakage signal is detected, the transformer converts the signal into an electrical signal and sends it to the leakage detection chip 15 for processing. The leakage detection chip 15 amplifies and filters the received signal and then sends it to the controller 11. The controller 11 receives the leakage signal processed by the leakage detection chip 15. After receiving the leakage signal, the controller 11 further analyzes and processes the signal according to a preset threshold or logic judgment rule. If it is determined that there is a leakage condition and the leakage signal reaches the set alarm condition, the controller 11 will perform the corresponding alarm operation. When the controller 11 determines that the alarm needs to be started, it will send an instruction to the alarm module 6. The alarm module 6 performs the corresponding alarm action according to the instruction, such as sending an audible and visual alarm signal to remind the user or operator to pay attention to the leakage condition. The controller 11 also establishes a connection with the remote server through the communication module 14. After detecting the leakage signal and processing it, the controller 11 can upload the leakage data (such as leakage current, occurrence time, location, etc.) to the remote server through the communication module 14. In this way, users or managers can view the monitoring data in real time through the remote server, understand the circuit status, and remotely process or dispatch the fault.

[0061] In addition, the control panel 18 is an interface for the user to interact with the monitoring device. It receives the user's operating instructions through the communication connection with the controller 11, and displays the device's working status, monitoring results and other information. The user can set parameters for the monitoring device, start / stop monitoring, etc. through the control panel 18.

[0062] Since the portable low-voltage leakage monitor device provided by the present application has a light appearance structure, and can realize intelligent setting of the leakage current through the controller function, and can also use the application to monitor the target circuit in real time and display it in real time on the on-site LCD screen and application, electricians can locate and solve problems more quickly, thereby improving the efficiency of fault elimination. This helps to reduce operation and maintenance costs and improve the operating efficiency of power companies.

[0063] In this embodiment, a leakage monitoring method running in an electronic device is provided. Figure 5 is a flow chart of a leakage monitoring method according to one embodiment of the present invention. Figure 5 As shown, the process includes the following steps:

[0064] Step S10, obtaining a leakage signal in the target circuit;

[0065] In the embodiment of the present invention, the target circuit can be understood as a circuit portion to which the leakage detection transformer is directly connected and monitored. By way of example, it is usually a circuit to which an electrical line or device is connected that may have a leakage risk, which is not limited here.

[0066] The leakage signal can be understood as a detectable signal generated when the current abnormally flows from the live conductor to the ground or other unexpected paths in the electrical system due to insulation damage, poor contact, design defects, etc., which is not limited here.

[0067] Acquiring the leakage signal in the target circuit can be understood as, illustratively, acquiring a detectable electrical signal generated due to insulation damage and other problems in the circuit portion directly connected and monitored by the leakage detection transformer, which is not limited here.

[0068] In the embodiments of the present invention, obtaining the leakage signal in the target circuit plays an important role in improving the safety of the electrical system, reducing power loss, optimizing the maintenance strategy, ensuring user safety and realizing intelligent management.

[0069] Step S11, preprocessing the leakage signal to obtain a preprocessed leakage signal;

[0070] In the embodiment of the present invention, preprocessing can be understood as performing a series of preliminary processing on the initial leakage signal before the initial leakage signal enters the main processor to improve the quality of the signal, reduce interference, and ensure the accuracy of subsequent processing. Exemplarily, the preprocessing operation can include amplifying the leakage signal, removing noise, sampling processing, etc., which are not limited here.

[0071] Preprocessing the leakage signal to obtain the preprocessed leakage signal can be understood as the detected original leakage signal is then sent to the preprocessing circuit. The preprocessing circuit usually performs operations such as amplification, filtering, sampling, signal conditioning, debiasing, and zero-crossing detection on the leakage signal, with the purpose of enhancing the signal, removing noise, and adjusting the signal characteristics, so that the preprocessed leakage signal is more suitable for subsequent digital signal processing, which is not limited here.

[0072] In the embodiment of the present invention, preprocessing the original leakage signal and then converting it into a higher quality and more reliable signal is a key step in ensuring accuracy and response speed in leakage monitoring. The preprocessed leakage signal provides accurate data for the main processor of the monitor, enabling it to more effectively identify and judge leakage conditions.

[0073] Step S12, performing leakage judgment on the preprocessed leakage signal based on a preset judgment condition to obtain a judgment result;

[0074] In the embodiment of the present invention, the preset judgment condition can be understood as a judgment standard for judging whether the circuit currently being detected has leakage. Exemplarily, the preset judgment condition can be a preset threshold or a logic judgment rule, which is not limited here.

[0075] Leakage judgment can be understood as the core controller of the portable low-voltage leakage monitor device analyzing and judging the pre-processed leakage signal according to a series of pre-set safety standards and circuit characteristic rules. Exemplarily, leakage judgment can be based on preset judgment conditions, usually including leakage current threshold, signal duration, frequency characteristics, signal morphology, etc. For example, a leakage current threshold is set. If the detected leakage current exceeds this threshold, it is considered that there is leakage in the circuit, which is not limited here.

[0076] The judgment result can be understood as the conclusion of whether there is leakage in the circuit and the severity of leakage after the portable low-voltage leakage monitor device analyzes and processes the signal according to its internal logic and algorithm. Exemplarily, the judgment results can be divided into the following types: 1. Leakage exists: If the pre-processed leakage signal meets the preset judgment conditions, such as the leakage current exceeds the set threshold and the duration reaches a certain standard, the portable low-voltage leakage monitor will determine that there is leakage in the circuit. At this time, the portable low-voltage leakage monitor will start the alarm mechanism, and immediately alert the relevant personnel through sound and light alarms, remote notifications, etc., and may record detailed information about the leakage, such as leakage current intensity, occurrence time, location, etc. 2. Leakage does not exist: If the pre-processed signal does not meet any preset leakage judgment conditions, the portable low-voltage leakage monitor will determine that there is no leakage in the circuit, and the system will remain in normal operation, which may be displayed as "normal" or "no abnormality" on the control panel or application. 3. Potential leakage risk: The portable low-voltage leakage monitor may be designed with more detailed judgment logic, which can identify leakage signals that are close to but have not yet reached the judgment conditions, which may indicate that there is a potential leakage risk in the circuit. In this case, the portable low-voltage leakage monitor will be marked as "warning" or "potential risk" to remind users to check to prevent possible leakage problems in the future. 4. System failure or false alarm: If there is a problem with the signal processing or judgment logic of the monitor, it may also cause a false alarm, that is, the system judges it as a leakage when there is no actual leakage. The judgment result in this case needs to be verified and reset to eliminate system failures to ensure the accuracy of the monitoring results, which is not restricted here.

[0077] Based on the preset judgment conditions, the pre-processed leakage signal is judged for leakage, and the judgment result can be understood as the portable low-voltage monitor using the preset electrical safety rules and circuit characteristics to analyze the data after signal processing to determine whether there is leakage in the circuit and give a corresponding warning. Exemplarily, after the signal preprocessing is completed, the portable low-voltage monitor will analyze the signal according to a series of preset judgment conditions. The preset judgment conditions are usually set based on electrical safety standards and circuit characteristics, such as leakage current threshold, signal duration, frequency characteristics, etc. For example, 30mA (milliamperes) is generally used internationally as the upper limit of human safety current, and the portable low-voltage monitor may use this value as the threshold for leakage judgment. The judgment result will determine the next operation of the monitor. If it is judged that there is leakage, the portable low-voltage monitor will start the alarm mechanism, such as issuing a warning through the built-in sound and light alarm module, or sending the alarm information to a remote server or application through a communication module. At the same time, the portable low-voltage monitor will record detailed information of the leakage event, such as leakage current size, duration, occurrence time, etc., for subsequent analysis. If it is determined that there is no leakage, the portable low-voltage monitor continues to maintain the monitoring state to ensure real-time detection of the circuit status, which is not restricted here.

[0078] In the embodiment of the present invention, the pre-processed leakage signal is judged based on the preset judgment conditions, that is, the portable low-voltage monitor uses the preset electrical safety rules and circuit characteristics to analyze the data after signal processing to determine whether there is leakage in the circuit and give a corresponding warning. This process ensures that the monitor can accurately and timely identify potential safety problems in the electrical system, providing important support for preventing electrical accidents and ensuring the stable operation of the power system.

[0079] Step S13, in response to the judgment result indicating that the target circuit has leakage and meets the reporting conditions, reporting prompt information, wherein the prompt information is used to prompt that the target circuit has leakage.

[0080] In the embodiment of the present invention, the reporting condition can be understood as a specific rule for the portable low-voltage leakage monitor to determine whether to report this information to an external system such as a remote server or application after determining that there is leakage in the circuit. The reporting conditions usually include but are not limited to the following points: 1. Leakage severity: The reporting mechanism is triggered only when the leakage current reaches or exceeds the preset severe threshold. This threshold may be set according to different safety standards and application scenarios, such as household electricity and industrial electricity may have different reporting thresholds. 2. Leakage duration: Short-term, instantaneous leakage may not trigger reporting because they may be caused by circuit transients or interference. Only when the leakage duration exceeds the preset time threshold is it considered an event that requires attention, thereby triggering reporting. 3. Repeated leakage events: If multiple leakage events are detected continuously in a short period of time, even if each event may not meet the reporting conditions individually, the repetitiveness may indicate a more serious problem, and reporting should be triggered at this time. 4. Specific time window: Reporting may only be effective during a specific time period, for example, at night or during non-working hours, when any leakage event may be more serious because there may be no personnel on site for immediate response. 5. Environmental factors: Taking into account the possible impact of environmental factors such as temperature and humidity on leakage detection, reporting is triggered only when the detected leakage signal excludes the interference of environmental factors and truly indicates a leakage problem. 6. Fault mode recognition: The portable monitor may be able to recognize specific types of leakage fault modes, such as phase-to-phase leakage, ground leakage, etc., and reporting is triggered only when a specific type of leakage mode is detected and preset as a leakage mode that needs to be reported. 7. Alarm level: Leakage events may be classified into different alarm levels according to their severity. The reporting mechanism is triggered only when the event reaches or exceeds the preset minimum alarm level. 8. Communication status: Whether the portable monitor is communicating normally. If the communication module is faulty or the network connection is unstable, it may not be reported immediately, but will try to reconnect first or report after the communication status is stable. 9. User-defined conditions: Users or power companies may set some customized reporting conditions, such as reporting only when leakage occurs on specific circuits or equipment. This is not restricted here.

[0081] The prompt information can be understood as information sent by the portable low-voltage leakage monitor to an external system such as a remote server, a power company's operation and maintenance system, or an application program after the portable low-voltage leakage monitor determines that there is leakage in the target circuit and this situation meets the preset reporting conditions. The purpose of the prompt information is to promptly notify the recipient that leakage is detected in the circuit so that corresponding safety measures can be taken or maintenance treatment can be performed, which is not limited here.

[0082] In response to the judgment result indicating that there is a leakage in the target circuit and the reporting conditions are met, the reporting prompt information can be understood as, for example, the portable low-voltage leakage monitor detects and analyzes the leakage condition of the target circuit through its internal leakage detection transformer and controller, and concludes that there is indeed a leakage in the circuit based on the preset judgment logic, and automatically sends a prompt information to the preset receiving system (such as a remote server, the power company's operation and maintenance system, application, etc.), which is not limited here.

[0083] In the embodiment of the present invention, the portable low-voltage leakage monitor can automatically make judgments based on real-time detection data and preset rules, and actively notify the external system when necessary. This mechanism greatly improves the efficiency and reliability of electrical safety early warning. In practical applications, this function is of great significance for preventing electrical fires, electric shock accidents, and reducing power losses, especially in unattended environments. It can timely and accurately convey key circuit status information, which helps maintain the safe and stable operation of the power system.

[0084] Acquiring leakage signals in the target circuit plays an important role in improving the safety of electrical systems, reducing power loss, optimizing maintenance strategies, ensuring user safety, and realizing intelligent management. Preprocessing the original leakage signal and then converting it into a higher quality and more reliable signal is a key step in ensuring accuracy and response speed in leakage monitoring. The preprocessed leakage signal provides accurate data for the main processor of the monitor, enabling it to more effectively identify and judge leakage conditions. Leakage judgment of the preprocessed leakage signal based on the preset judgment conditions is the process in which the portable low-voltage monitor uses the preset electrical safety rules and circuit characteristics to analyze the signal-processed data to determine whether there is leakage in the circuit and give corresponding warnings. This process ensures that the monitor can accurately and timely identify potential safety problems in the electrical system, providing important support for preventing electrical accidents and ensuring the stable operation of the power system. The portable low-voltage leakage monitor can automatically make judgments based on real-time detection data and preset rules, and actively notify the external system when necessary. This mechanism greatly improves the efficiency and reliability of electrical safety warnings. In practical applications, this function is of great significance for preventing electrical fires, electric shock accidents and reducing power losses. Especially in unmanned environments, it can convey key circuit status information in a timely and accurate manner, which helps maintain the safe and stable operation of the power system.

[0085] Through the above steps, by obtaining the leakage signal in the target circuit; preprocessing the leakage signal to obtain the preprocessed leakage signal; performing leakage judgment on the preprocessed leakage signal based on preset judgment conditions to obtain a judgment result; in response to the judgment result indicating that there is leakage in the target circuit and the reporting conditions are met, reporting prompt information, wherein the prompt information is used to prompt that there is leakage in the target circuit, achieving intelligent setting and real-time monitoring, electricians can locate and solve problems more quickly, thereby improving the efficiency of fault elimination, thereby achieving the technical effect of reducing operation and maintenance costs and improving the operating efficiency of power companies, thereby solving the technical problem in related technologies that maintenance personnel will expand the scope of power outages and increase the number of power outages while waiting for the next tripping while supplying power, which will seriously affect users' normal power consumption.

[0086] Optionally, in step S13, the leakage monitoring method further includes:

[0087] Step S131, uploading the judgment result and leakage data to a remote server.

[0088] In the embodiment of the present invention, the remote server can be understood as a computer system or network device located outside the location of the portable low-voltage leakage monitor device, which is used to receive, store, process and analyze data information sent by the monitor. Exemplarily, the remote server can be used for data storage, data processing and analysis, remote control and configuration, etc. The existence of the remote server greatly expands the function of the portable low-voltage leakage monitor, making it not only a local detection device, but also a part of a networked and intelligent electrical safety monitoring system, which is not limited here.

[0089] Uploading the judgment result and leakage data to the remote server can be understood as a data communication process between the portable low-voltage leakage monitor and the remote monitoring system. For example, after receiving the data uploaded by the monitor, the remote server will further process the information, such as storage, analysis, comparison with historical data, etc., which is not limited here.

[0090] In the embodiment of the present invention, uploading the judgment results and leakage data to a remote server is a key step in realizing remote monitoring and electrical safety management, which enables power companies and users to monitor circuit status in real time, respond to electrical safety events in a timely manner, and improve the reliability and safety of the power system. In the context of the Internet of Things and smart grids, this data upload mechanism is an important component for realizing intelligent monitoring of electrical equipment and fault warning.
