Description

Technical Field

[0001] The invention relates to the technical field of tension wire laying in power transmission line engineering, and in particular to a transmission line tension wire laying monitoring method and system for fault and abnormality positioning. Background Art

[0002] Transmission lines often use tension pay-off to dismantle old lines or install new lines. Its main advantage is that it can achieve a high tension pay-off speed and work efficiency while ensuring the quality of pay-off. It can also further reduce the scope of land used for policy processing and reduce the loss of young crops. The current transmission line tension pay-off mainly uses a traction machine to pull the guide rope, traction rope and conductor, and the tension machine recovers the guide rope and traction rope. The pulley is hung under each cross arm of the tower to provide a tension pay-off path. However, in the process of tension pay-off, it is easy for the conductor to break, the conductor to jump, the board to flip or the balance hammer to rest on the conductor. Once such a fault occurs, the tension machine must stop traction immediately, and the traction can only be resumed after the cause is found by the guardians at various locations. However, for the transmission line with a long tension section, it is limited by the manpower to ensure that the entire line is covered by a dedicated person to monitor the conductor status, and it is impossible to accurately identify the fault point and quickly respond to the brake in the first time, and it is difficult to eliminate safety hazards.

[0003] In order to solve the problem that the conductor status of the long tensioning section of the transmission line project cannot be monitored manually throughout the line, a Chinese patent with publication number CN115190376A, which was published on October 14, 2022, proposes a board movement status monitoring system for the tension wire-laying process, which is mainly aimed at the board movement status monitoring device of the tension wire-laying process, and improves the traditional board by adding a GNSS positioning module, an inclination sensor, and a rotary connector with a tension detection function, so as to detect the status information of the board in real time, thereby realizing effective monitoring of the tension wire-laying state. However, this solution can only judge whether the tension wire-laying state is normal or not by observing the board state, and realize the early warning of the tension wire-laying state. It cannot quickly identify the location of the fault point, and still needs to manually troubleshoot the fault point. The identification speed of the tension wire-laying fault point is slow, and the safety of the tension wire-laying is difficult to guarantee. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art that when the tension wire-laying state monitoring is realized by modifying the board and detecting the board state information in real time, the position of the fault point cannot be identified, manual fault point investigation is required, and the tension wire-laying fault point identification speed is slow. A transmission line tension wire-laying monitoring method and system for fault and abnormal location is provided, and the tension wire-laying state is monitored by adding a monitoring device to the tension wire-laying process, and the full-line monitoring of the transmission line tension wire-laying state is realized by analyzing the angular velocity change of each pulley on the tension wire-laying path. The fault condition of the target conductor tension wire-laying can be automatically identified, and the abnormal position is further located in combination with the pulley position, without manual fault point investigation, thereby improving the fault identification efficiency of the transmission line tension wire-laying and ensuring the safety of the transmission line tension wire-laying.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0020] The fault monitoring threshold of the wiring state in each tension pay-off stage is determined according to the corresponding angular velocity standard value and angular velocity fluctuation range of each pulley.

[0021] Furthermore, determining the current tension pay-off stage based on the collected angular velocity includes determining the pulley type of each pulley, matching the collected angular velocity with the corresponding angular velocity variation range according to the pulley type of each pulley, and determining the current tension pay-off stage of each pulley according to the matching result of each pulley.

[0024] Obtaining the angular velocity fluctuation value between every two adjacent pulleys, and comparing the angular velocity fluctuation value with the corresponding routing state fault monitoring threshold;

[0025] If the angular velocity fluctuation value exceeds the wiring state fault detection threshold, it is determined that there is a tension wire release fault in the target wire, and the abnormal position is located on the target wire between two adjacent pulleys whose angular velocity fluctuation value exceeds the wiring state fault detection threshold;

[0026] If the angular velocity fluctuation value between two adjacent pulleys does not exceed the wiring state fault monitoring threshold, it is determined that the tension pay-out of the target wire section is normal.

BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Figure 1 It is a schematic diagram of a process of the present invention. DETAILED DESCRIPTION

[0037] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0038] Example

[0039] A transmission line tension wire-laying monitoring system, comprising a wire-laying state monitoring device and a mobile terminal device, wherein the wire-laying state monitoring device is arranged on a tension wire-laying path, is communicatively connected with the mobile terminal device, and performs transmission line tension wire-laying monitoring, wherein the wire-laying state monitoring device comprises an angular velocity acquisition module, a positioning module, and a data processing module;

[0040] The angular velocity acquisition module is used to acquire the angular velocity of each pulley on the tension pay-off path;

[0041] The positioning module is used to obtain the position information of each pulley on the tension wire release path;

[0042] The data processing module is used to judge the tension wire-paying state fault according to the angular velocity of each pulley on the tension wire-paying path, and to locate the abnormality in combination with the position information of each pulley.

[0043] The angular velocity acquisition module and the positioning module are both provided with multiple sub-units, the number of the sub-units is consistent with the number of pulleys, each pulley is provided with a sub-unit of the angular velocity acquisition module and a sub-unit of the positioning module, and the sub-unit of the angular velocity acquisition module and the sub-unit of the positioning module on each pulley exchange data with the data processing module through wireless communication.

[0044] Specifically, the subunits of the angular velocity acquisition module and the subunits of the positioning module are installed externally, without destroying the original tension wire release tool structure, thus ensuring the reliability of the tension wire release device. Before the pulley is lifted into the air, the subunits of the wiring status monitoring device are first fixed on the pulley.

[0045] The data interaction between the subunits of the angular velocity acquisition module, the subunits of the positioning module and the data processing module is carried out using cellular networking communication technology, without the need for external mobile signal base stations, and the reliability of information exchange is high.

[0046] The angular velocity acquisition module may be an angular velocity sensor, an acceleration sensor or other element that can directly or indirectly obtain angular velocity values.

[0047] The positioning module may be a positioning module such as GPS, Beidou, etc. which can obtain specific geographic location information.

[0048] The mobile equipment terminal comprises an alarm module, and the alarm module is used to receive the fault judgment result and abnormal positioning result of the data processing module in the wiring status monitoring device, and issue an alarm.

[0049] The mobile equipment terminal can be connected to the data processing module by wireless communication, can receive the fault information and abnormal position positioning information sent by it, and send out warnings to on-site operators in time.

[0050] The mobile device terminal is also provided with a trigger module, and the trigger module is used to send a wake-up signal to the angular velocity acquisition module to trigger the angular velocity acquisition module to operate.

[0051] In addition to receiving the alarm information sent by the wiring status monitoring device, the mobile device terminal can also control the operation of the wiring status monitoring device. In order to avoid the rotation generated during the pulley lifting process from affecting the tension wire-laying monitoring, after the tension wire-laying starts, a wake-up signal is sent through the mobile device terminal to trigger the angular velocity acquisition module to start the transmission line tension wire-laying monitoring method.

[0052] The mobile device terminal may be a mobile phone, a computer, a handheld data terminal or other intelligent device capable of information interaction.

[0053] A transmission line tension and wire-laying monitoring method for fault and abnormal location, such as Figure 1 As shown, including

[0054] Determine the target conductor and obtain the tension pay-out path of the target conductor;

[0055] Set the fault monitoring threshold of the wiring status in each tension pay-off stage;

[0056] The angular velocity of each pulley on the tension pay-off path is collected in real time, and the tension pay-off stage of each pulley is determined based on the collected angular velocity;

[0057] According to the matching of the corresponding routing status fault detection threshold in the tension pay-off stage, the target conductor fault is judged in combination with the corresponding angular velocity, and the abnormal position is determined according to the position of each pulley.

[0058] Before starting to lay out the wires, it is necessary to set an initial tension value based on design requirements and line characteristics. This value is usually calculated based on multiple factors such as the span of the line tower, the type and specification of the conductor, and the external environment (such as wind load, ice load, temperature change, etc.). After determining the initial tension value, the traction machine can be used as a basis to pull the target conductor and start laying out the wires.

[0059] In the early stage of laying out the wires, the tension will gradually increase because the conductors have not been fully unfolded and may be affected by factors such as ground friction and bending. As the conductors are gradually unfolded and the laying out process proceeds, the tension will gradually stabilize. When the final laying out is about to be completed, the tension needs to be adjusted again to ensure that the conductor tension at the hanging point is appropriate to ensure the safe operation of the transmission line.

[0060] Therefore, according to the tension change in the tension pay-off process, this embodiment specifically divides the tension change stage into an initial adjustment stage, a stable operation stage, and an end and finishing stage.

[0061] As the tension fluctuates, the angular velocity of the pulley will also show different characteristics. For example, in the initial stage, when the tension needs to be gradually established and the pay-off equipment needs to be adjusted, the angular velocity of the pulley may be relatively low, and the frequency and amplitude of fluctuations will be large. In the stable operation stage, the pay-off speed will remain in a relatively constant range, and the angular velocity of the pulley will also tend to be stable. In the end and finishing stage, since the target conductor needs to be temporarily anchored and subsequent tightening and accessory installation work needs to be prepared, the angular velocity of the pulley will gradually decrease until it stops.

[0062] Therefore, the angular velocity of each pulley can be collected in real time to determine the tension pay-off stage it is in, and then the corresponding routing status fault detection threshold can be set according to the different characteristics exhibited by the pulley in different tension pay-off stages to avoid misjudgment of faults.

[0063] Subsequently, the state of the tension pay-off on the path can be determined by comparing the angular velocities of different pulleys, so as to provide timely warning and rapid fault location.

[0064] The step of determining the target conductor and obtaining the tension pay-out path of the target conductor includes:

[0065] Determine the target conductor and obtain the corresponding laying requirements of the target conductor;

[0066] Determine the starting point and end point of the target wire according to the wire laying requirements, and define the planning range of the wire laying path according to the starting point and end point;

[0067] Obtain the factors affecting the wire-laying path within the path planning range, and set the tension wire-laying path of the target conductor based on the factors affecting the wire-laying path and the starting point and end point.

[0068] Since the tension pay-off needs to be set according to its specific pay-off requirements, it is necessary to first obtain the pay-off requirements corresponding to the target conductor.

[0069] The line laying needs include repair, upgrade, replacement and new line construction.

[0070] After determining the line laying requirements, determine the starting and end points of the target conductor for tension line laying, and then determine the line direction according to the line laying requirements, and then determine the planning range of the line laying path based on the positions of the starting and end points. Obtain the line laying path influencing factors such as the tower position, terrain conditions, crossing objects, climate, etc. within the planning range of the line laying path, and make reasonable wiring design according to the specific conditions of the influencing factors of each line laying path, such as the position and spacing of each support (such as tower), and determine the tension line laying path.

[0071] The setting of the fault monitoring threshold of the wiring state in each tension pay-off stage includes:

[0072] Identify the conductor type of the target conductor, and match the corresponding historical tension pay-out data according to the tension pay-out setting on the tension pay-out path;

[0073] Extract features from historical tension pay-off data, cluster the extracted feature data, and divide the tension pay-off stages according to the clustering results;

[0074] Determine the angular velocity change data of each pulley in each tension pay-off stage according to the historical tension pay-off data;

[0075] The angular velocity standard value and angular velocity fluctuation range of each pulley are set based on the angular velocity variation data of each pulley in each tension pay-off stage;

[0076] The fault monitoring threshold of the wiring state in each tension pay-off stage is determined according to the corresponding angular velocity standard value and angular velocity fluctuation range of each pulley.

[0077] Since different types of pulleys may be in different positions and functional areas during the release process, they may be in different tension release stages at the same time. For example, some pulleys may be involved in the release of the guide rope, while other pulleys may have started the release of the ground wire.

[0078] Therefore, the historical tension pay-off data that can be used for reference is first determined according to the conductor type of the target conductor and the specific tension pay-off setting, wherein the tension pay-off setting includes the pulley type, the tension control strategy, and the like.

[0079] After determining the historical tension pay-off data, the angular velocity change data of each pulley is determined, and the complete angular velocity change of each pulley during the tension pay-off process under the same tension pay-off scenario for processing this type of conductor is determined.

[0080] In order to determine the angular velocity variation characteristics of each pulley in different tension pay-off stages, the tension pay-off stages are divided first. The division of the tension pay-off stages is closely related to the tension data displayed by the conductor. Therefore, the tension data part of the historical tension pay-off data is obtained, and the features are extracted. The extracted feature data is clustered by a clustering algorithm (such as the K-means clustering algorithm), and the tension pay-off stages are divided according to the corresponding time of the tension data contained in each cluster.

[0081] Combined with the corresponding data collection time, the angular velocity change data of each pulley in each tension pay-off stage is determined.

[0082] Then, the angular velocity of each pulley in each tension pay-off stage is averaged, and the calculated angular velocity average is used as the angular velocity standard value. Then, the maximum angular velocity and the minimum angular velocity of each pulley in each tension pay-off stage are used to set the angular velocity fluctuation range.

[0083] When setting the fault detection threshold for the wiring status, there are two cases. One is that the pulleys for angular velocity comparison are in the same tension pay-off stage. In this case, the fluctuation values ​​of the upper and lower limits of the angular velocity fluctuation range are used as the wiring status fault monitoring threshold. Another case is that the pulleys for angular velocity comparison are in different tension pay-off stages. In this case, the difference between the angular velocity standard values ​​of the two tension pay-off stages is used as the wiring status fault monitoring threshold.

[0084] Determining the current tension pay-off stage based on the collected angular velocity includes determining the pulley type of each pulley, matching the collected angular velocity with the corresponding angular velocity variation range according to the pulley type of each pulley, and determining the current tension pay-off stage of each pulley according to the matching result of each pulley.

[0085] The method matches the corresponding fault detection threshold of the wiring state according to the tension release stage, judges the target wire fault in combination with the corresponding angular velocity, and determines the abnormal position according to the position of each pulley, including:

[0086] Obtain the pulley type of each pulley, and determine the corresponding routing state fault detection threshold according to the pulley type corresponding to every two adjacent pulleys and the tension pay-off stage in which they are located;

[0087] Obtaining the angular velocity fluctuation value between every two adjacent pulleys, and comparing the angular velocity fluctuation value with the corresponding routing state fault monitoring threshold;

[0088] If the angular velocity fluctuation value exceeds the wiring state fault detection threshold, it is determined that there is a tension wire release fault in the target wire, and the abnormal position is located on the target wire between two adjacent pulleys whose angular velocity fluctuation value exceeds the wiring state fault detection threshold;

[0089] If the angular velocity fluctuation value between two adjacent pulleys does not exceed the wiring state fault monitoring threshold, it is determined that the tension pay-out of the target wire section is normal.

[0090] Taking the fault judgment of the nth pulley as an example, the data processing module will receive the angular velocities of the n-1th pulley, the nth pulley and the n+1th pulley, and judge the pulley type and the tension stage of the n-1th pulley, the nth pulley and the n+1th pulley respectively, so as to determine the corresponding routing status fault monitoring threshold.

[0091] Specifically, the n-1th pulley and the nth pulley are both in the stable operation stage, the n+1th pulley is in the end and closing stage, and the angular velocity of the n-1th pulley is , the angular velocity of the nth pulley is , the angular velocity of the n+1th pulley is Since the n-1th pulley and the nth pulley are in the same stable operation stage, their routing state fault detection threshold is a. Since the nth pulley and the n+1th pulley are in different stable operation stages, their routing state fault detection threshold is b.

[0092] The data processing module will calculate the angular velocity difference between the nth pulley and the n-1th pulley. Compare it with the routing status fault monitoring threshold a, and calculate the angular velocity difference between the nth pulley and the n+1th pulley Compared with the routing status fault monitoring threshold b, only and Only when the nth pulley is judged to be operating normally and no fault occurs, in other cases, it is judged that there is a fault, and the abnormality is located in combination with the specific comparison situation.

[0093] like and , it is judged that there is a tension pay-off abnormality between the nth pulley and the n-1th pulley.

[0094] like and , it is judged that there is a tension pay-off abnormality between the nth pulley and the n+1th pulley.

[0095] like and , it is determined that there are tension pay-off anomalies between the nth pulley and the n-1th pulley and between the nth pulley and the n+1th pulley.

[0096] The above-described embodiment is only a preferred solution of the present invention and does not limit the present invention in any form. There are other variations and modifications without exceeding the technical solution described in the claims.
