Description

Technical Field

[0001] This invention relates to the field of power systems, and more particularly to a method, device, equipment, and medium for unlocking control of power distribution network towers. Background Technology

[0002] In modern power systems, power poles and towers in the distribution network are critical infrastructure for power transmission and distribution, and their daily operation, maintenance, and repair are frequently carried out on-site. Due to the complexity of the distribution network, the large number of devices, and the possibility of temporary power supply adjustments or bypass power supply, if workers misjudge the energized state of the poles when climbing them, serious personal safety accidents such as electric shock and falls from heights are highly likely, posing a significant risk to the operation of the power grid. Therefore, implementing reliable unlocking control for the poles is the last and most critical technical safety barrier to forcibly isolate hazards at the physical connection level, ensure the safety of workers, and guarantee the compliance of power grid operations.

[0003] Currently, common unlocking control methods mainly rely on a simple combination of a work permit management system, mechanical or electronic unlocking devices, and back-end dispatch instructions. Specifically, the work plan is approved through paper or electronic permits, and authorization information is manually or semi-automatically transmitted to the site; the unlocking device then unlocks based on the received fixed password or preset time period. However, this method has significant drawbacks: the work permit is completely disconnected from the real-time energized status of the tower, and the authorization logic is static, unable to dynamically adjust according to the actual "energized" or "de-energized" state on site. This means that even when the tower is accidentally energized, it may still be unlocked because the password is valid or it is within the authorized time period, creating a fatal hidden danger. Summary of the Invention

[0004] This invention provides a method, device, equipment, and medium for controlling the unlocking of power distribution network poles, which can improve the security of pole unlocking control in power distribution networks.

[0005] In a first aspect, embodiments of the present invention provide a method for unlocking power distribution network towers, comprising: The received work order corresponding to the working tower is parsed to obtain the working tower number, work time window and work requirement electrical status information, and the actual tower number, first voltage value data and first electric field strength data corresponding to the working tower within the preset time period are obtained. Based on the first voltage value data and the first electric field strength data, the real-time charged state and the reliability index are calculated respectively. The working tower number is matched with the actual tower number to obtain a first judgment result, and the preset time period is matched with the working time window to obtain a second judgment result; The electrical status information of the operation requirements is matched with the real-time energized status to obtain a third judgment result, and the preset credibility index threshold is matched with the credibility index to obtain a fourth judgment result. If all the judgment results are satisfactory, then the working tower is unlocked.

[0006] This application embodiment obtains the tower number, work time window, and electrical status information of the work requirements by parsing the work order; secondly, by acquiring real-time electrical quantity data (first voltage value data and first electric field strength data) of the tower, and calculating objective and quantitative real-time energized status and reliability indicators, it achieves dynamic perception of the actual risks on-site and the reliability of their judgment, providing core factual input and quality evaluation for safety decision-making, and overcoming the uncertainty of relying solely on plans or manual judgment; furthermore, by using work plan information (tower number, electrical status of work requirements, etc.)... The system matches and judges on-site perceived information (actual tower number, real-time energized status, and reliability indicators) across multiple key dimensions (first to fourth judgment results), constructing a multi-verified, indispensable, and interconnected safety criterion system. This system mandates that the tower object, operation time, electrical status, and the reliability of their judgments must simultaneously meet preset conditions. From the logical source, it systematically eliminates any single risk point of authorized unlocking due to misidentification, overtime work, inconsistent status, or unreliable measurement, forming a three-dimensional safety joint defense mechanism. Finally, by setting the strict joint condition of "all judgment results are passed" as the sole prerequisite for unlocking, and controlling the physical lock action accordingly, a closed-loop safety decision-making process from information verification to physical execution is achieved, ensuring that any request that does not meet all safety conditions is automatically and reliably blocked. In summary, the various technical means are interconnected, jointly realizing a fully automated, highly reliable safety interlocking control from operation instructions to on-site status and final execution, significantly improving the safety level of tower operations.

[0007] As a preferred example of the first aspect, the calculation of the real-time charged state and the reliability index based on the first voltage value data and the first electric field strength data includes: The first voltage value data and the first electric field intensity data are respectively processed by moving average to obtain the second voltage value data and the second electric field intensity data. Based on the second voltage value data, the second electric field strength data, the preset upper limit of the voltage value threshold, the preset lower limit of the voltage value threshold, the preset upper limit of the electric field strength threshold, and the preset lower limit of the electric field strength threshold, a continuous confirmation rule is used to determine the real-time charged state; wherein, the second voltage value data includes a preset number of voltage values, and the second electric field strength data includes a preset number of electric field strengths.

[0008] In this preferred example, firstly, the original electrical quantity data is processed by moving average to effectively filter out instantaneous interference and power frequency fluctuations, resulting in smooth and stable second voltage and electric field strength values, providing a reliable data foundation for subsequent judgments. Secondly, based on preset upper and lower thresholds, a "continuous confirmation rule" is introduced for state discrimination. This requires that the data must meet the threshold conditions for multiple consecutive sampling periods before triggering a state reversal. This mechanism effectively avoids misjudgments and frequent state jumps caused by instantaneous fluctuations or jitter near the threshold. The combination of these two methods achieves highly reliable and interference-resistant real-time judgment of the energized state of the tower, providing accurate and stable core input for subsequent authorization decisions and fundamentally improving the safety margin of the interlocking control.

[0009] As a preferred example of the first aspect, the real-time energized state is obtained by judging based on the second voltage value data, the second electric field strength data, a preset upper voltage threshold, a preset lower voltage threshold, a preset upper electric field strength threshold, and a preset lower electric field strength threshold using a continuous confirmation rule; wherein, the second voltage value data includes a preset number of voltage values, and the second electric field strength data includes a preset number of electric field strengths, including: If each voltage value in the second voltage value data is greater than or equal to the preset voltage value threshold upper limit for a first preset number of consecutive times, or if the second electric field strength data is greater than or equal to the preset voltage value threshold upper limit for a first preset number of consecutive times, then the real-time energized state is determined to be energized. If each voltage value in the second voltage value data is less than or equal to the preset voltage value threshold lower limit for a first preset number of consecutive times, and the second electric field strength data is less than or equal to the preset electric field strength threshold lower limit for a first preset number of consecutive times, then the real-time charged state is determined to be uncharged.

[0010] In this preferred example, a dual criterion of voltage and electric field strength is employed. A sustained exceedance of either signal by the voltage or electric field strength is sufficient to classify the state as "energized," improving the sensitivity of detecting dangerous conditions. The determination of "not energized" requires both voltage and electric field strength to be continuously below the lower limit, a more stringent condition that effectively prevents misjudgments of a safe state due to a single sensor malfunction or localized interference. The requirement for a first preset number of consecutive checks constitutes a "continuous confirmation rule," ensuring that state transitions are based on a continuous and stable trend, rather than instantaneous fluctuations, effectively suppressing misjudgments caused by interference. These measures collectively achieve interference-resistant, misjudgment-preventing, and highly reliable energized state identification, providing crucial and reliable decision-making basis for subsequent interlocking control, fundamentally improving the level of safety protection.

[0011] As a preferred example of the first aspect, the calculation of the real-time charged state and the reliability index based on the first voltage value data and the first electric field strength data includes: The second voltage value data is divided by the preset upper limit of the voltage value threshold to obtain a first ratio, and the second electric field strength data is divided by the preset upper limit of the electric field strength threshold to obtain a second ratio. The credibility index is then determined based on the first ratio and the second ratio.

[0012] As a preferred example of the first aspect, the step of controlling the working tower to unlock if all the judgment results are passed includes: If all the judgment results are passed, then the user's unlocking request for the working tower is responded to, and a dynamic authorization instruction is generated according to the unlocking request, and then the working tower is controlled to be unlocked according to the dynamic authorization instruction.

[0013] As a preferred example of the first aspect, the step of parsing the received work ticket corresponding to the working tower to obtain the working tower number, work time window, and work requirement electrical status information includes: The system receives the work order corresponding to the working tower and parses the work order using a natural language processing method to obtain the working tower number, the work time window, and the electrical status information of the work requirements.

[0014] As a preferred example of the first aspect, the step of matching the preset time period and the operation time window to obtain the second judgment result includes: Determine whether the preset time period is within the operation time window. If so, output the second determination result as "pass"; otherwise, output the second determination result as "fail".

[0015] In a second aspect, the present invention provides a power distribution network tower unlocking control device, comprising: a data acquisition module, a first processing module, a second processing module, a third processing module and a fourth processing module; The data acquisition module is used to parse the work ticket corresponding to the received work tower to obtain the work tower number, work time window and work requirement electrical status information, and to obtain the actual tower number, first voltage value data and first electric field strength data corresponding to the work tower within a preset time period. The first processing module is used to calculate the real-time charged state and the reliability index based on the first voltage value data and the first electric field strength data, respectively. The second processing module is used to match the working tower number with the actual tower number to obtain a first judgment result, and to match the preset time period with the working time window to obtain a second judgment result; The third processing module is used to match the electrical status information of the operation requirements with the real-time energized status to obtain a third judgment result, and to match the preset credibility index threshold with the credibility index to obtain a fourth judgment result. The fourth processing module is used to control the working tower to unlock if all the judgment results are passed.

Based on the second voltage value data, the second electric field strength data, the preset upper limit of the voltage value threshold, the preset lower limit of the voltage value threshold, the preset upper limit of the electric field strength threshold, and the preset lower limit of the electric field strength threshold, a continuous confirmation rule is used to determine the real-time charged state; wherein, the second voltage value data includes a preset number of voltage values, and the second electric field strength data includes a preset number of electric field strengths.

[0017] As a preferred example of the second aspect, the real-time charged state is obtained by judging based on the second voltage value data, the second electric field strength data, a preset upper limit voltage threshold, a preset lower limit voltage threshold, a preset upper limit electric field strength threshold, and a preset lower limit electric field strength threshold using a continuous confirmation rule; wherein, the second voltage value data includes a preset number of voltage values, and the second electric field strength data includes a preset number of electric field strengths, including: If each voltage value in the second voltage value data is greater than or equal to the preset voltage value threshold upper limit for a first preset number of consecutive times, or if the second electric field strength data is greater than or equal to the preset voltage value threshold upper limit for a first preset number of consecutive times, then the real-time energized state is determined to be energized. If each voltage value in the second voltage value data is less than or equal to the preset voltage value threshold lower limit for a first preset number of consecutive times, and the second electric field strength data is less than or equal to the preset electric field strength threshold lower limit for a first preset number of consecutive times, then the real-time charged state is determined to be uncharged.

[0018] As a preferred example of the second aspect, the calculation of the real-time charged state and reliability index based on the first voltage value data and the first electric field strength data includes: The second voltage value data is divided by the preset upper limit of the voltage value threshold to obtain a first ratio, and the second electric field strength data is divided by the preset upper limit of the electric field strength threshold to obtain a second ratio. The credibility index is then determined based on the first ratio and the second ratio.

[0019] As a preferred example of the second aspect, the step of controlling the working tower to unlock if all the judgment results are passed includes: If all the judgment results are passed, then the user's unlocking request for the working tower is responded to, and a dynamic authorization instruction is generated according to the unlocking request, and then the working tower is controlled to be unlocked according to the dynamic authorization instruction.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone.

[0034] It should be noted that on-site safety during power distribution network pole and tower operations has always been a key focus and challenge in power operation and maintenance. With the continuous improvement of urban and rural power grid structures, the density and frequency of on-site operations have significantly increased, leading to frequent safety accidents caused by mistakenly climbing energized poles. To address this risk, existing pole and tower interlocking systems primarily rely on work permit systems, interlocking devices, and back-end dispatching for safety control. However, these three systems generally suffer from insufficient coordination and information gaps.

[0035] Existing work permit management systems primarily rely on manual data entry or platform review to generate work plans and authorization information. While the processes are standardized, they have low correlation with the status of on-site equipment. In practice, work permits serve only as paper or electronic vouchers, failing to establish a direct and effective linkage with the real-time electrical status of the site. Some interlocking systems employ timed authorization, manual issuance of unlocking commands, or single-password control, authorizing unlocking solely based on the work time period or backend approval information. This static or single-channel authorization mechanism is prone to safety hazards due to information delays, misoperations, or untimely status synchronization. For example, a tower may be energized but still unlockable based on a time window or authorization signal, posing a high risk of workers accidentally climbing an energized tower.

[0036] Furthermore, traditional interlocking devices lack automatic identification and closed-loop feedback of the real-time electrical status of the towers, and the on-site unlocking process relies on manual confirmation and judgment. Even with the introduction of wireless communication and remote authorization in some intelligent solutions, their control logic is still mainly based on time or manual triggering, and cannot dynamically generate accurate interlocking or unlocking commands according to the actual electrical status and work order requirements, thus limiting their ability to prevent accidental entry.

If so, output the second determination result as "pass"; otherwise, output the second determination result as "fail".

[0055] For more detailed steps and working principles of this embodiment, please refer to the relevant description in Embodiment 1, but not limited to these descriptions.

[0056] In summary, this application's embodiments obtain the tower number, work time window, and electrical status information of the work requirements by parsing the work order; secondly, by acquiring real-time electrical quantity data (first voltage value data and first electric field strength data) of the tower, and calculating objective and quantitative real-time energized status and reliability indicators accordingly, dynamic perception of the actual risks on-site and the reliability of their judgment is achieved, providing core factual input and quality evaluation for safety decision-making, overcoming the uncertainty of relying solely on plans or manual judgment; furthermore, by using work plan information (tower number, work requirements, electrical status information, etc.)... The system matches and judges the status of the pole with on-site perceived information (actual pole number, real-time energized status, and reliability indicators) across multiple key dimensions (first to fourth judgment results). This constructs a multi-verified, indispensable, and interconnected safety criterion system. This system mandates that the pole object, operation time, electrical status, and the reliability of their judgments must simultaneously meet preset conditions. It systematically eliminates any single risk point from the logical source—such as misidentification, overtime work, inconsistent status, or unreliable measurement—that would lead to authorized unlocking, forming a three-dimensional safety joint defense mechanism. Finally, by setting the strict joint condition of "all judgment results are passed" as the sole prerequisite for unlocking, and controlling the physical lock's action accordingly, a closed-loop safety decision-making process from information verification to physical execution is achieved, ensuring that any request that does not meet all safety conditions is automatically and reliably blocked. In summary, the various technical means are interconnected, jointly realizing a fully automated, highly reliable safety interlocking control from operation instructions to on-site status and final execution, significantly improving the safety level of pole operations.
