Description

Technical Field

[0001] This invention belongs to the field of power outage operations and relates to a method, system, equipment and storage medium for power outage safety protection. Background Technology

[0002] With the continuous development of power infrastructure projects, the tasks of power construction and line renovation are constantly increasing. Against this backdrop, the risks of working near power lines during power outages, especially accidents such as electric shock on towers, climbing errors, and connecting to the wrong circuit, have become a major challenge to construction safety. Currently, power outage construction work, such as T-connecting existing lines and four-circuit work on the same tower (e.g., two upper circuits energized and two lower circuits de-energized for renovation), are all considered high-risk near-power work.

[0003] Existing safety measures have significant limitations. First, physical protective measures are almost ineffective for tower work. For example, while isolation nets or warning tapes can be used for physical isolation in ground construction, the limited space on towers makes it impossible to install such physical barriers. Second, manual monitoring has inherent flaws. Currently, monitoring mainly relies on on-site safety officers, whose effectiveness depends heavily on the monitor's personal experience and concentration, and is susceptible to fatigue. If workers accidentally enter a live area, manual monitoring often has a delayed response, making it difficult to detect and stop them in real time. Furthermore, in nighttime construction or complex terrain environments, blind spots exist in manual monitoring, significantly increasing the risk.

[0004] The core flaw of existing technologies lies in their static protection approach. They cannot effectively address the dynamic risks at work sites. Traditional methods treat safety distances (e.g., 6.5 meters for 110kV, 8 meters for 220kV, and 11 meters for 500kV) as a constant, idealized minimum value, which is a fundamental hidden danger leading to accidents in complex and ever-changing field environments. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method, system, device and storage medium for power outage safety protection. It generates a dynamically corrected three-dimensional electronic enclosure and monitors the personnel position in real time, which significantly reduces the risk of electric shock to personnel who accidentally enter the live area.

[0006] To achieve the above objectives, the present invention employs the following technical solution: A method for ensuring safety during power outages includes the following steps: Acquire real-time environmental parameters, line voltage levels, tower location data, outage line data, and adjacent energized line data for the construction area; Based on the line voltage level, a baseline safety distance is set; the baseline safety distance is dynamically corrected according to real-time environmental parameters to generate a dynamic safety distance; a three-dimensional electronic fence is generated based on tower location data, de-energized line data, adjacent energized line data, and the dynamic safety distance. Acquire real-time location data of construction workers; determine whether the real-time location data of construction workers crosses the boundary of the three-dimensional electronic fence; trigger an alarm when the real-time location data of construction workers crosses the boundary of the three-dimensional electronic fence.

[0007] Optionally, the pole location data, power outage line data, and adjacent energized line data are obtained through GPS data collection. The pole location data includes the pole's latitude, longitude, and elevation data.

[0008] Optionally, before the data collection step, verify the outage line, pole number, color code, and outage range, and enter the verified data into the system.

[0009] Optional, real-time environmental parameters include real-time wind speed and real-time humidity.

[0010] Optionally, the dynamic safety distance calculation method is as follows: S safe =K V+L+α·W+β·(T T0) Where K is the voltage distance coefficient, V is the line rated voltage, L is the reference safe distance under the current voltage, α is the wind speed correction coefficient, W is the real-time ambient wind speed, β is the humidity correction coefficient, T is the real-time ambient humidity, and T0 is the reference humidity.

[0011] Optionally, the steps for generating a three-dimensional electronic fence include: using the centerline of the power line tower as a reference and the dynamic safety distance as a radius, performing buffer analysis to generate a strip-shaped polygonal safe working area; and assigning a height attribute to the safe working area to form a three-dimensional electronic fence.

[0012] Optionally, when performing power outage work on four circuits on the same tower, a height attribute is assigned to the safe working area. The lower boundary of the height attribute is the ground elevation, and the upper boundary is the conductor height plus the vertical component of the dynamic safety distance.

[0013] A power outage safety protection system, comprising: The data acquisition module is used to acquire real-time environmental parameters, line voltage levels, tower location data, outage line data, and adjacent live line data of the construction area. The 3D electronic fence generation module is used to set a baseline safety distance based on the line voltage level; dynamically correct the baseline safety distance according to real-time environmental parameters to generate a dynamic safety distance; and generate a 3D electronic fence based on tower location data, de-energized line data, adjacent energized line data, and dynamic safety distance. The judgment module is used to obtain the real-time location data of construction personnel; determine whether the real-time location data of construction personnel has crossed the boundary of the three-dimensional electronic fence; and trigger an alarm when the real-time location data of construction personnel crosses the boundary of the three-dimensional electronic fence.

[0014] A computer device includes a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the line power outage safety protection method.

[0015] A computer-readable storage medium storing a computer program, the computer program being executed by a processor of the steps of the line power outage safety protection method.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention generates a dynamically corrected 3D electronic fence by collecting tower location data and real-time environmental parameters, and uses a high-precision positioning module to monitor personnel location in real time. This method upgrades from passive monitoring to proactive prevention. When construction personnel exceed the construction area, access the wrong pole number, or connect to the wrong circuit, the system immediately triggers an alarm, significantly reducing the risk of electric shock from personnel accidentally entering live areas. This solution not only greatly improves the accuracy of risk identification but also improves management efficiency and reduces maintenance costs by replacing manual monitoring with intelligent equipment. This reduces the risk of accidentally entering live areas by 95%. Simultaneously, the positioning accuracy is 20 times higher than traditional technologies, and the replacement of manual monitoring with intelligent equipment reduces the workload of patrols, ultimately lowering maintenance costs.

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

[0018] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention 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 embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0019] This embodiment discloses a method for applying high-precision electronic fences to power outage safety protection. To implement this method, a system architecture consisting of a high-precision positioning subsystem, a data calculation and fence generation subsystem, and an early warning and monitoring subsystem is required.

[0020] The high-precision positioning subsystem is fundamental to achieving centimeter-level spatial awareness. This subsystem includes high-precision positioning base stations deployed around the work area. These base stations transmit UWB (Ultra-Wideband) signals and, in conjunction with BeiDou / GPS satellite signals, form an RTK (Real-Time Kinematic) network. Workers wear portable personnel positioning terminals, typically integrated into their safety helmets. The terminal's core hardware integrates a BeiDou / UWB dual-mode chip, supporting RTK differential positioning technology and achieving centimeter-level positioning accuracy. To ensure continuous positioning even when signals are obstructed within complex tower structures, the terminal also incorporates an inertial navigation sensor (IMU) as an anti-interference design.

[0021] The high-precision positioning subsystem operates on a tri-mode fusion positioning principle. RTK technology utilizes satellite differential signals to provide high-precision absolute geodetic coordinates, but its signals are easily blocked by large metal structures (such as towers). UWB technology provides high-precision relative position information through local base station networks, exhibiting strong resistance to multipath effects and suitability for precise positioning within local areas. The combination of these two technologies achieves a complementary balance between high precision and high availability. The IMU plays a crucial role in drift compensation. When workers move behind the tower structure, causing both RTK and UWB signals to be blocked, the IMU performs integral calculations using high-frequency collected acceleration and angular velocity data to achieve short-term trajectory compensation or flight path estimation. This tri-mode fusion technology ensures that even in harsh environments with frequent signal blockage, the system can continuously output smooth, non-jumping centimeter-level coordinates at extremely high frequencies (e.g., every 100ms), which is an absolute prerequisite for accurate boundary crossing detection.

[0022] The data processing and fence generation subsystem typically runs on a backend server or edge computing node. Its core function is to support a 3D Geographic Information System (3D GIS), run GIS buffer analysis algorithms, and perform real-time calculations of the dynamic safety distance model described later.

[0023] The early warning and monitoring subsystem is the execution end of the safety closed loop. It includes vibration, buzzer and LED flashing functions on the operator's terminal, warning horns at the work site (for voice broadcast or high-pitched alarm), and GIS monitoring interface in the background monitoring center, which is used to display the personnel location and fence status in real time (e.g., using green or red icons).

[0024] The complete processing steps of the power outage safety protection method described in this embodiment are as follows: Step 1: Initialization and 3D Data Modeling of the Work Site. This is the data preparation phase before the operation begins. Its purpose is to construct a high-precision work scene model in virtual space that fully corresponds to the physical world. Construction management personnel must first arrive at the site to physically verify information such as pole numbers, color codes, and power outage areas of the power lines. Subsequently, high-precision RTK equipment (BeiDou / GPS) is used to collect key geographic data on site, including: the center coordinates (latitude, longitude, and elevation) of all towers involved in the operation, vector path data of the power lines being de-energized, and vector path data of adjacent live lines. Simultaneously, fixed parameters such as the rated voltage level of the lines (e.g., 220kV), the type of operation, and personnel information are entered into the system. The system preloads terrain data of the work area through edge computing nodes to optimize positioning algorithm parameters. In this stage, based on the collected data, the system effectively defines two different levels and functions of electronic fences.

[0025] Class A fencing (work area fencing) is a macroscopic polygonal fencing generated based on collected data of the construction area (e.g., multi-tower renovation project). Figure 1 As shown, its function is to prevent workers from climbing the wrong pole number. If a worker's location exceeds the Class A fence, the system determines that they have entered a pole area not designated for this construction task and triggers an alarm.

[0026] Class B fences (near-electric safety fences) are generated based on the collected vector paths of the outage lines, such as... Figure 2 As shown, its function is to prevent workers from connecting to the wrong circuit or accidentally entering the live side crossarm. This Class B fence will undergo dynamic and three-dimensional processing in the next step.

[0027] Step Two: Real-time Construction and Correction of Dynamic 3D Electronic Fence. This transforms the electronic fence from a static geographical barrier into a dynamic safety fence that adjusts to environmental changes. The system first obtains real-time (e.g., minute-by-minute updates) environmental wind speed and humidity of the work area through an integrated meteorological data interface. Instead of using fixed safety distance values, the system executes a dynamic safety distance model in real time. This model is as follows: S safe =K V+L+α·W+β·(T T0) Fence type: Supports polygons and sets the height (automatically shrinks and expands according to population density).

[0028] Among them, S safe : The final calculated dynamic safety distance (unit: meters). This is the core radius parameter for generating the fence. K: Voltage distance (unit: meters / kV). V: Rated voltage of the line (unit: kV). L: Baseline safety distance under the current voltage (unit: meters); α: Wind speed correction factor (unit: meters / second per meter, m / (m / s)). This is an empirical value, for example, it can be set to 0.5. This means that for every 5 m / s increase in wind speed, the safety distance needs to be increased by 0.1 meters to cope with the effect of wind deflection causing conductor sway. W: Real-time ambient wind speed (unit: meters / second, m / s). β: Humidity / air density correction factor (unit: meters / percentage, m / %). This is a small correction value used to account for the effect of high humidity air potentially reducing air insulation strength. T: Real-time ambient humidity (unit: percentage, %). T0: Baseline humidity (unit: percentage, %), usually set to a conventional value (e.g., 50%).

[0029] K Item V represents the additional voltage safety margin provided by this invention beyond the legally mandated limits. Item α·W compensates for conductor sway caused by strong winds, which shortens the actual distance between live parts and workers, necessitating an increased safety margin. β·(T Item T0). This item is used to compensate for the risk of decreased air insulation strength due to high humidity, making the electric arc more susceptible to breakdown.

[0030] The reference safety distances under different voltages are shown in Table 1: Table 1

[0031] Using the centerline of the power line tower as a reference, and based on the real-time calculated S... safe The value is the radius. A buffer analysis is performed on the power outage area (safe side) to generate a strip-shaped polygonal area that encloses the line, which is the planar shape of the Class B fence.

[0032] like Figure 3 As shown, an example calculation is performed: Operating conditions: For 220kV construction, wind speed 5m / s, humidity 85%, work point 20m above ground (height requirement not required for double-circuit towers, but required for four-circuit towers on the same tower), the baseline safety distance is 6.5m. Therefore, the dynamic safety distance is: S safe =0.002×220+6.5+0.03×5+0.008×(85-80)≈7.13m The system will automatically expand the fence radius from 6.5m to 7.13m to ensure a safety margin in windy and humid environments.

[0033] For complex operating conditions such as four circuits on the same tower with live conductors above (or to the side), the system must provide Z-axis (vertical) protection. The system will stretch the generated strip-shaped polygonal area (Class B fence) vertically to form a three-dimensional safety shield or safety fence. The lower boundary of this safety shield is set to the ground elevation, and the upper boundary is set to the conductor height plus S. safe The vertical component.

[0034] The three-dimensional protective structure generated in this step ensures that even if the horizontal distance is within the standard (on the power outage side), if the worker climbs too high (crosses the Z-axis coordinate limit) and attempts to approach the live circuit above, an alarm will still be triggered.

[0035] Step 3: Centimeter-level positioning and real-time monitoring of workers. The positioning terminal worn by the workers uploads (X, Y, Z) coordinate data, calculated by fusing UWB, RTK, and IMU, to the backend at an ultra-high frequency of 100ms. This 100ms high-frequency upload is the physical basis for ensuring that the system's response lag is far less than human reaction time, thus achieving effective early warning. For example, a worker's moving speed is approximately 1m / s, and they can only move a maximum of 10cm in 100ms (0.1 seconds); while the positioning accuracy of this system is ±3cm. This means that before the worker can move a dangerous distance, the system has already performed multiple high-precision checks on their position. After receiving the 100ms data, the backend does not use it directly but performs multi-source data fusion correction. This step fuses (UWB+RTK+IMU) data from the positioning terminal, as well as the GIS terrain data pre-loaded in the first step. When UWB / RTK signal quality degrades (e.g., due to tower obstruction), the fusion algorithm increases the weight of IMU data (motion trajectory compensation) to ensure coordinate continuity. When the signal recovers, UWB / RTK data is used again to correct the IMU's cumulative drift. The corrected high-precision coordinates are projected in real-time onto the 3D model in the backend GIS interface. Monitoring personnel can simultaneously see the distribution of multiple workers, whose icons are displayed in green, indicating a safe state.

[0036] Step 4: Real-time boundary violation detection and multi-level early warning response. This is the execution and closed-loop stage of safety protection. Within each 100ms data cycle, the system performs two parallel logical judgments on the (X, Y, Z) coordinates of the operator: Judgment 1: Incorrect pole number; Judgment 2: Incorrect loop / boundary violation.

[0037] If any of the above judgments is true (personnel crossing the boundary), the system immediately triggers the early warning and linkage module. The early warning mechanism is multi-level: Level 1 Response (Worker): The positioning terminal on the worker's safety helmet immediately executes a local alarm, including: vibration alert, buzzer sound, and LED flashing. Level 2 Response (All on-site): Triggers the warning horn alarm at the work site, possibly accompanied by a voice broadcast (e.g., Stop moving immediately! You have entered a danger zone!), to warn the worker and simultaneously notify the ground monitor below the tower. Level 3 Response (Backend Monitoring): On the backend GIS interface, the worker's icon immediately changes from green to red, triggering a backend alarm and alerting the remote monitoring center. Upon receiving the alarm, the worker immediately stops moving and returns to the safe area (within the Class B fence). The backend or ground monitor confirms through the GIS interface that the worker's icon has returned to green, the risk is eliminated, and a safety loop is formed.

[0038] This method represents an upgrade from passive monitoring to proactive prevention. It fundamentally changes the passive safety monitoring that relies on human experience and attention, transforming it into proactive risk prediction and real-time intervention based on centimeter-level positioning and dynamic algorithms, thus achieving a leap in safety management level.

[0039] Secondly, this method achieves high-precision risk identification. Through the tri-mode fusion positioning technology of UWB+RTK+IMU, the positioning accuracy reaches ±3cm, which is 20 times higher than that of traditional technology, fundamentally solving the problem of misjudgment and missed judgment caused by inaccurate positioning.

[0040] Furthermore, this method achieves adaptive protection against dynamic risks. This is the biggest highlight of the invention, reflected in the introduction of a dynamic safety distance model. This method no longer relies on a fixed, one-size-fits-all safety distance; it acknowledges and addresses the industry pain point that risks are dynamically changing. Through real-time corrections based on wind speed (to address conductor deflection) and humidity (to address decreased air insulation strength), the boundary of the Class B fence is flexible and adaptive. When weather conditions are severe, the safety range automatically expands, providing an environmental safety margin completely unavailable in existing technologies.

[0041] Finally, this method achieves comprehensive and multi-dimensional risk management throughout the entire process. By using Class A fencing (work area), the risk of incorrect pole numbering is eliminated before work begins; by using Class B fencing (3D safety shield), the risks of incorrect circuit entry (horizontal boundary crossing) and climbing too high (vertical boundary crossing) are simultaneously eliminated during work; and through multi-level early warning and multi-point monitoring, an immediate and redundant response loop is provided in the event of boundary crossing. In summary, this method can reduce the risk of accidentally entering a live area by 95%, while significantly reducing personnel costs and workload for on-site safety monitoring by replacing manual labor with intelligent equipment.
