Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of cross-line control, and in particular to a cross-line protection method and system based on dynamic adjustment. Background Art
[0002] In power engineering construction, tensioning and setting out conductors across existing power lines is a critical step in ensuring the safe connection of transmission lines. When newly installed conductors need to cross existing power lines and other facilities, improper tension control during the setting-out process, or insufficient spacing between the new and old lines, can easily lead to scraping and entanglement between the new conductors and the facilities being crossed. This can damage the lines at best, or even cause severe accidents such as widespread power outages and traffic disruptions.
[0003] To avoid these issues during the crossing and laying process, safety measures were typically implemented by erecting a protective spanning structure or lowering the spanning structure to the ground. However, due to the complex terrain, constructing spanning structures not only required significant manpower, material resources, and time, but also posed a risk of structural collapse due to the unstable terrain. Lowering the spanning structure also involved coordination among multiple parties and prolonged power outages, making implementation extremely challenging.
[0004] Therefore, it has become a more common means of protection to protect the crossed lines by tying bamboo strips or PVC pipes. However, this protection method relies on manual pulling of insulating ropes on the ground to adjust the protection position in real time. During the line laying operation, high-altitude winds can cause the new conductors to shift and deviate from the predetermined position. Ground personnel are limited by terrain obstructions and long distances, making it difficult to accurately judge the relative position of the new conductors and the crossed lines with the naked eye. In this case, the protective materials often cannot be moved to the critical position in time, resulting in direct contact between the new conductors and the crossed lines, causing wear of the line insulation layer and breakage of the metal wire strands. Subsequent repair work is not only costly, but may also affect the stability and reliability of regional power supply. Summary of the Invention
[0005] The purpose of the present invention is to overcome the shortcomings of the prior art in which the position of protective materials is manually adjusted, the offset of the conductor cannot be accurately judged, the position of the protective material is difficult to adjust in time, and the new conductor is in direct contact with the crossed line, causing damage to the line. A method and system for crossing line protection based on dynamic adjustment is provided. The method accurately sets the initial crossing position by planning the path of the conductor to be laid, effectively optimizes the subsequent adjustment efficiency, and during the construction process, dynamically monitors the real-time position of the conductor to be laid, quickly calculates its relative distance from the initial crossing position, and quickly identifies the offset in combination with environmental influencing factors, and then generates a corresponding equipment adjustment strategy for the offset, thereby realizing automatic protection adjustment of the conductor to be laid and the crossed line, reducing the wear risk of the line, and effectively improving the safety and construction efficiency of the tension line laying operation across the line.

During the construction process, the real-time position of the conductor to be laid is further dynamically monitored to quickly calculate its relative distance from the initial crossing position, and the offset is quickly identified in combination with environmental influencing factors. Once the offset is detected, the corresponding equipment adjustment strategy can be automatically generated according to the offset to achieve automated protection adjustment for the conductor to be laid and the line to be crossed, avoiding construction interruption or rework caused by protection failure, reducing the risk of line wear, and effectively improving the safety and construction efficiency of the tension line laying operation across the line, ensuring the stability and reliability of power supply in the corresponding area;

[0053] (3) By obtaining the relative distance between the conductor to be placed and the crossing position, a preliminary judgment of the position offset can be made. Then, combined with the environmental influencing factors, a refined judgment of the position offset can be made, avoiding the interference of environmental factors and reducing the number of adjustments. Different types of position offsets can also be quickly identified, and the adjustment objects can be accurately selected according to the position offset type, thereby optimizing the response speed and processing efficiency of the protection adjustment.

[0057] The present invention will be further described below with reference to the accompanying drawings and examples.
[0058] Example: During the construction process of crossing and laying out the lines, the crossed lines are protected by tying bamboo strips or PVC pipes. This can, through physical isolation, buffer the friction and collision between the conductors to be laid and the crossed lines to a certain extent during the laying out process, and play a basic protective role for the crossed lines.
[0059] However, under the influence of environmental factors, during the actual construction process, the contact angle and position between the crossed line and the conductor to be placed actually change dynamically. The traditional method of manually dragging the bundled objects to adjust the position is difficult for construction workers to accurately judge the actual contact angle and position of the conductor and the crossed line. In addition, there is a certain time lag between manual operation and problem discovery, analysis and judgment, and implementation of adjustments, making it difficult to respond to position adjustment needs in a timely manner. As a result, the adjustable protection scheme fails to play its expected role and increases the risk of line damage.
[0060] In order to solve the above problems, this embodiment proposes a cross-line protection method based on dynamic adjustment, such as Figure 1 Shown, including:
[0061] Obtain the planned path of the conductor to be placed, and set the initial crossing position of the conductor to be placed on the crossing line accordingly;
[0062] Place the protective device of the conductor to be placed at the initial crossing position, and drag and place the conductor to be placed according to the planned path;
[0063] Based on the real-time position information of the conductor to be placed, the relative distance between the conductor to be placed and the initial crossing position is calculated, and the position offset is judged in combination with environmental influencing factors;
[0064] A corresponding equipment adjustment strategy is generated based on the position offset judgment result until the conductor to be placed passes through the protective device and crosses the crossed line.
[0065] Crossing wire laying construction often faces complex and diverse terrain, such as mountainous areas, rivers, and densely built-up urban areas. It is also affected by meteorological conditions. In order to accurately judge the reasonable direction and crossing position of the conductor in such a complex environment, it is necessary to pre-plan the tension wire laying path of the conductor to be laid, so as to avoid the lines in dangerous areas such as complex terrain in advance, plan a safe laying trajectory, ensure that the conductor to be laid maintains a safe distance from the surrounding environment during the laying process, avoid safety accidents such as line short circuit and breakage caused by improper path selection, and ensure the safety of the tension wire laying construction process. The position of the intersection is then predicted based on the tension wire laying path to correspond to the initial crossing position of the protective device, providing data support for the subsequent position offset and providing a clear reference point for the placement of the protective device, so that the protective device can accurately cover the key areas where the conductor to be laid may come into contact with the crossed line.
[0066] Specifically, the step of obtaining the planned route of the conductor to be placed and correspondingly setting the initial crossing position of the conductor to be placed on the crossing line includes:
[0067] Based on the payout section, the conductor information of the conductor to be paid out, and the equipment parameters of the tension payout equipment, the planned path of the conductor to be paid out is obtained;
[0068] Predict the intersection point based on the path of the line being crossed and the planned path of the conductor to be placed;
[0069] Combined with the dynamic influencing factors of the intersection position, the deviation tolerance distance of the intersection position is calculated to determine the fluctuation range of the intersection position on the crossed line;
[0070] According to the placement requirements and movement distance limit of the protection device, the initial crossing position of the conductor to be placed on the crossed line is selected from the crossing position range.
[0071] Geographic information such as the topography and traffic conditions of the payout section directly impacts the feasibility and safety of laying the conductors. Furthermore, conductor information, such as material, diameter, weight, and tensile strength, along with the tension payout equipment parameters, such as maximum tension and payout speed adjustment range, further determine the mechanical properties and motion patterns of the conductors during the payout process. Therefore, in the early stages of construction, information about the payout section, the conductors to be laid, and the parameters of the tension payout equipment is obtained through channels such as the geographic information system and the tension payout construction plan. By establishing a mechanical model of the conductors to be laid and simulating the construction environment, the payout trajectories under different working conditions are simulated. Finally, based on indicators such as construction difficulty, safety risks, and construction costs, the optimal payout trajectory is selected as the planned path for the conductors to be laid.
[0072] Furthermore, through spatial geometry algorithms, three-dimensional modeling is performed on the line path of the line to be crossed and the planned path of the conductor to be placed. Collision detection analysis is performed based on dimensions such as the horizontal direction of the path, the vertical height difference, and the curvature of the line to predict the potential intersection position of the two paths in space, and accurately locate the area where the conductor to be placed and the line to be crossed may intersect, providing data support for the subsequent determination of the intersection position.
[0073] Among them, the dynamic influencing factors of the intersection position include meteorological conditions such as wind speed, wind direction, and temperature changes, terrain micro-environment such as valley wind and local airflow disturbances, and subtle deviations in equipment operation such as line tension fluctuations and uneven speed.
[0074] Using historical data from similar construction environments, we constructed a correlation model between various dynamic influencing factors and intersection position offsets. Then, through probabilistic statistics and uncertainty analysis, we calculated the maximum offset distance of the intersection position that would allow for protection under different combinations of influencing factors, known as the offset tolerance distance. This then determined the fluctuation range of the intersection position on the crossed line. As long as the protective device is set within this fluctuation range, the tension payout can achieve its protection function if the conductor to be deployed does not drift and the planned path is followed.
[0075] The placement requirements of the protection device involve factors such as installation space, stability, and ease of connection with equipment. Its moving distance is limited by the mechanical structure, driving capability, and response time of the protection device. Therefore, within the determined fluctuation range of the crossing position, based on the constraints of the above-mentioned protection device, optimization algorithms such as particle swarm optimization are used to screen out the best position that meets the installation feasibility and dynamic adjustment requirements, and set it as the initial crossing position of the conductor to be placed on the crossed line, ensuring that the protection device can not only effectively cover the crossing area but also have the basic conditions for flexible adjustment.
[0076] After completing the planning path and the setting of the initial crossing position, set the protection device to the initial crossing position, and then drag and drop the conductors according to the planned path to carry out the crossing line laying project.
[0077] During the crossing and setting out construction process, the real-time position of the conductor to be laid is collected in real time, and then the relative position distance between the conductor to be laid and the initial crossing position is calculated to achieve real-time monitoring of the position offset of the conductor to be laid.
[0078] Specifically, the calculation of the relative distance between the conductor to be placed and the initial crossing position based on the real-time position information of the conductor to be placed, and the determination of the position offset in combination with environmental influencing factors include:
[0079] Based on the real-time position information of the conductor to be placed, the relative position distance between the conductor to be placed and the initial crossing position is calculated;
[0080] Acquire a first determination result of a position offset based on the relative position distance;
[0081] Based on the first judgment result and the real-time position information of the conductor to be placed, the position offset judgment is performed in combination with the environmental influencing factors.
[0082] Through laser displacement sensors, angle sensors and other equipment, the spatial position of the conductor to be placed is collected in real time, the real-time position information of the conductor to be placed is obtained, and then the relative position distance between the conductor to be placed and the initial intersection position is calculated through spatial geometric algorithms.
[0083] Then, by comparing the calculated relative position distance with the preset threshold, calculating the difference, deviation rate and other indicators between the two, the degree of position offset between the conductor to be placed and the protection can be judged, and obvious position offset situations can be quickly identified.
[0084] However, considering that the position offset result obtained simply by comparing the preset threshold value cannot take into account the impact of factors such as environmental fluctuations on the position offset, it is difficult to distinguish between normal swing and position offset, which is prone to misjudgment or missed judgment.
[0085] Therefore, environmental influencing factors are introduced in the position judgment process to correct the first judgment result, improve the accuracy of the judgment of position offset, and assist in judging the cause of the position offset, so as to improve the efficiency of the subsequent targeted equipment adjustment strategy for position adjustment.
[0086] Specifically, the position offset judgment based on the first judgment result and the real-time position information of the conductor to be placed, combined with environmental influencing factors, includes:
[0087] When the first judgment result is that the relative position distance exceeds the preset threshold, calculating the environmental impact value according to the environmental impact factor;
[0088] Modify the first judgment result according to the environmental impact value;
[0089] When the corrected first judgment result is that the relative position distance exceeds the preset threshold, the position offset type is identified in combination with the environmental impact value;
[0090] When the first judgment result or the corrected first judgment result is that the relative position distance does not exceed the preset threshold, it is determined that no position offset occurs.
[0091] Environmental factors include multi-dimensional data such as wind speed and direction, which can be collected by on-site meteorological monitoring equipment. A pre-built relationship model between each environmental factor and the forces acting on the conductor to be deployed is used to quantify the impact of each environmental factor on the position change of the conductor to be deployed.
[0092] Taking wind impact as an example, a wind impact model can be pre-built based on aerodynamics. Calculate the force exerted by the wind on the conductor to be placed, and then convert the wind force into the displacement value of the conductor to be placed based on the conductor information of the conductor to be placed. In the above formula, The force exerted by wind on the conductor to be released, is the air density, is the wind speed, is the air resistance coefficient, A is the windward area of the conductor to be released, It is the angle between the wind direction and the conductor to be laid.
[0093] Then, the quantitative results of the influence of each environmental influencing factor on the position change of the conductor to be placed are aggregated according to dimensions such as the direction of action, and the environmental impact value of the environmental influencing factor on the position deviation of the conductor to be placed is determined.
[0094] After obtaining the environmental impact value, the changing trend of the environmental impact value is further determined. If the changing trend of the environmental impact value shows fluctuation, the reasonable influence of the environmental impact value on the position of the conductor to be placed is eliminated from the original position distance difference to exclude the normal position changes caused by environmental factors, so that the judgment result can better reflect the actual offset situation.
[0095] If, after removing the environmental impact value, the corrected first judgment result still shows that the position distance difference exceeds the preset threshold, it proves that there is indeed a position offset. At the same time, in order to improve the efficiency of formulating subsequent equipment adjustment strategies, the environmental impact value is combined to identify the type of position offset.
[0096] However, if the environmental impact value exceeds the preset reasonable range from the beginning and the change trend is also stable, it proves that under the influence of the current environmental impact factor, the conductor to be placed will have a continuous position shift. In this case, it can be directly determined that there is indeed a position shift, and subsequent position shift type identification can be carried out directly.
[0097] Machine learning and other recognition algorithms can be used to identify the type of positional offset. For example, if the environmental impact value is high and the fit with the positional offset trend is high, it can be determined that the offset is caused by environmental factors. If the positional distance difference is still large after correction by the environmental impact value, and the environmental impact value is within a reasonable range, it can be determined that the offset is caused by payout-related factors such as abnormal payout equipment. In other cases, the offset can be determined to be the result of the combined influence of environmental factors and payout equipment.
[0098] Regardless of whether it is the original first judgment result or the corrected first judgment result, as long as the relative position distance does not exceed the preset threshold, it is determined that no position offset has occurred, which can effectively avoid false movement of the protection device caused by environmental influencing factors such as environmental fluctuations.
[0099] If it is determined that no position deviation has occurred, there is no need to adjust the equipment and the crossing line laying work can continue according to the current operating conditions.
[0100] When determining that there is a position offset, it is necessary to combine the identification results of the position offset type and propose corresponding equipment adjustment strategies to optimize the adjustment efficiency and accuracy of the position offset.
[0101] Specifically, based on identifying the position offset type, generating a corresponding device adjustment strategy based on the position offset determination result includes:
[0102] Obtaining a position offset type according to a position offset judgment result, and selecting a protective device and / or a tension pay-off device as an adjustment object based on the position offset type;
[0103] Based on the relative position distance, a device adjustment strategy corresponding to the adjustment object is generated.
[0104] Environmentally influenced deviations are typically caused by factors like wind and temperature fluctuations. For example, strong winds can cause conductors to oscillate significantly and continuously, exceeding their normal trajectory. In these situations, protective devices, as protective structures directly in contact with the crossed conductors, can quickly respond to environmental changes by adjusting their position and angle, isolating the conductor to be placed from the crossed line and reducing the risk of collision. Therefore, protective devices are chosen as the target for adjustment, as they reflect the rapidly changing nature of environmental factors affecting conductor position.
[0105] The root cause of the tension pay-off equipment-dominated deviation is mainly due to equipment abnormalities such as the deviation of the tension pay-off equipment's operating status from expectations. Directly adjusting the tension control module, speed regulation system and other related equipment parameters of the tension pay-off equipment can correct the conductor pay-off trajectory deviation from the source and restore the conductor to be paid to its normal path. Therefore, the tension pay-off equipment is the object of adjustment for this type of deviation.
[0106] If the position offset is affected by both environmental factors and the tension pay-out equipment, it is necessary to coordinate the real-time protection of the protective device and the trajectory correction of the tension pay-out equipment to cope with complex working conditions and ensure the safety of the pay-out construction. In this case, a combination of the two needs to be selected as the adjustment object.
[0107] Among them, when it is determined that the position offset type is an environmental factor-dominated offset and the adjustment object is a protection device, the compensation offset is obtained according to the relative position distance;
[0108] The crossing position is regenerated according to the compensation offset, and the protection device is moved to the regenerated crossing position.
[0109] First, the offset required for adjustment is determined directly based on the relative distance difference. This additional offset is then added to the initial crossing position to regenerate the crossing position, thereby re-determining the intersection point between the conductor to be laid and the line being crossed. This approach preserves the design specifications of the planned path while incorporating the real-time adjustment requirements brought about by environmental changes. This ensures that the regenerated crossing position not only meets construction safety standards but also accurately adapts to the actual position of the conductors in the current environment, ensuring effective protection against crossing lines.
[0110] When it is determined that the position offset type is a tension pay-off device-dominated offset and the adjustment object is the tension pay-off device, the current device parameters of the tension pay-off device are obtained;
[0111] The actual laying path is constructed based on the real-time position information of the conductor to be laid, and the relationship between equipment parameters and path offset is established in combination with the planned path;
[0112] The compensation offset is obtained according to the relative position distance, and the equipment parameters of the tension pay-off device are adjusted in combination with the correlation between the equipment parameters and the path offset.
[0113] The actual payout path for the conductor to be laid is constructed using real-time position information, while the planned path is the designed trajectory under ideal working conditions. When the tension payout equipment experiences an anomaly, the actual payout path will directly deviate from the planned path, making it difficult to ensure the successful execution of the span payout work. Therefore, various equipment parameters of the tension payout device, such as tension value, payout speed, and motor speed, are collected from other completed span payout scenarios. This data is also used to collect data on the deviation between the actual payout path of the conductor to be laid and the planned path, such as horizontal displacement, vertical displacement, and curvature change. Data analysis algorithms, such as regression analysis and machine learning algorithms, are then used to identify potential correlations between equipment parameter changes and path deviations.
[0114] On this basis, the compensation offset is obtained according to the relative position distance difference after correction of the environmental impact value. Combined with the established correlation between equipment parameter changes and path offset, the equipment parameters of the tension pay-off device that need to be adjusted are calculated.
[0115] If the position offset is determined to be affected by both environmental factors and the tension payout device, the same approach is used as above, except that the compensation offset for the tension payout device is first calculated based on the relative position distance difference after correction of the environmental impact value. This is then used to calculate the corresponding tension payout device parameters that need to be adjusted. The adjusted planned path is then determined based on the adjusted tension payout device parameters. The compensation offset for the protection device is then determined based on the environmental impact value to regenerate the crossing position and achieve the final position adjustment.
[0116] Another aspect of this embodiment further provides a dynamically adjusted cross-line protection system, including:
[0117] A protection device 1 is provided on the crossed line and is used to isolate the discharged conductor from the crossed line;
[0118] The moving mechanism 2 is connected to the protection device and is used to adjust the position of the protection device on the crossed line and fix the protection device;
[0119] The dynamic adjustment device 3 is connected to the moving mechanism and the tension pay-off device for controlling the cross-line pay-off, and is used to judge the position offset according to the real-time position information of the conductor to be paid, and generate an equipment adjustment strategy according to the judgment result.
[0120] Among them, the protective devices are binding materials such as bamboo strips and PVC pipes, which can isolate the conductors to be laid and the crossed lines to prevent friction between the two during the laying process.
[0121] The moving mechanism comprises:
[0122] A walking pulley 21 is provided on the bridged line and is used for moving on the bridged line;
[0123] The motor group 22 is connected to the travel pulley and is used to control the moving direction of the travel pulley;
[0124] A drag mechanism 23 is connected to the traveling pulley and the protection device, respectively, and is used to drive the movement of the protection device according to the movement of the traveling pulley;
[0125] The brake mechanism 24 is connected to the motor unit and is used to fix the moving mechanism.
[0126] To ensure the safety device's mobility on the crossed line, a travel pulley must be placed and then electrically connected to the motor unit. This motor controls the forward and reverse rotation of the travel pulley, moving it forward or backward along the crossed line. A towing mechanism is connected to the travel pulley at one end and to the safety device at the other, pulling it along. To ensure the device's stability, a braking mechanism is also incorporated to secure the mobile mechanism to the crossed line, preventing it from slipping.
[0127] If the protective device needs to be moved, the motor group can be used to control the brake mechanism to loosen the clamp, allowing the mobile mechanism to slide on the crossed line. When the protective device reaches the predetermined crossing position, the motor group can be used to control the brake mechanism to contract the clamp, clamping the crossed line to prevent the mobile mechanism from sliding on the crossed line.
[0128] The dynamic adjustment device comprises:
[0129] Tracking module 31, used to collect real-time location information of the crossed line and environmental impact factors of the protection device;
[0130] The data processing module 32 is connected to the tracking module and is used to determine the position offset based on the real-time position information of the conductor to be released, and to generate an equipment adjustment strategy for the moving mechanism or the tension pay-off device based on the determination result;
[0131] The communication module 33 is respectively connected to the data processing module, the mobile mechanism and the tension pay-off device for controlling the cross-line pay-off, and is used to issue the equipment adjustment strategy.
[0132] In order to optimize the system volume, the dynamic adjustment device can be integrated into the moving mechanism.
[0133] Among them, the tracking module integrates a variety of data acquisition devices such as video module, micro-shooting module, laser sensor, meteorological collection device, etc. that can collect location information and environmental data.
[0134] The data processing module can be a microprocessor that integrates algorithms such as corresponding position offset analysis, identification of position offset conditions, and generation of equipment adjustment strategies.
[0135] In order to realize the execution of the device adjustment strategy, a communication module is further set up, which can send the device adjustment strategy generated by the data processor to the corresponding execution device. The communication module can be a 4G, 5G, Bluetooth and other communication modules.
[0136] The said spanning wire-laying system also includes a power supply module 4, which provides power for the protection device and the dynamic adjustment device and can be a high-power lithium battery or a photovoltaic panel.
[0137] In order to realize the whole process monitoring of the overall spanning line laying process, a mobile terminal device 5 such as a mobile phone or a tablet can be further provided to realize information interaction with the data processing module through the communication module, so as to obtain the protection adjustment status of the data processing module in real time, and to directly issue corresponding instructions to realize the adjustment of the protection system.
[0138] The overall structure diagram of the above-mentioned crossing line protection system is as follows: Figure 2 shown.
[0139] The embodiment described above is only a preferred solution of the present invention and does not limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solution described in the claims.
