Description

Technical Field

[0001] This invention relates to the field of overhead contact line infrastructure inspection technology, and in particular to a method and apparatus for determining the dynamic lifting amount of the contact wire. Background Technology

[0002] This section is intended to provide background or context for the embodiments of the invention set forth in the claims. The description herein is not an admission that it is prior art simply because it is included in this section.

[0003] Contact wire rise is a crucial aspect of studying the vibration behavior of overhead contact systems. Excessive rise will alter the pantograph's working height, impacting current collection quality and exacerbating fatigue in the droppers and positioning devices. Conversely, insufficient rise indicates excessive dynamic stiffness, intensifying friction and wear at the pantograph-catenary contact point. Therefore, continuous contact wire rise can guide overhead contact system maintenance. By combining statistical distribution patterns of rise with data on span, contact force, tension, suspension type, and contact wire material, early warnings of overhead contact system operation can be provided, supporting the optimization of the pantograph-catenary relationship.

[0004] Currently, the main method for determining the contact wire rise is to use measuring equipment (such as contact sensor measurement, non-contact image measurement, etc.) fixed next to the line to detect static and dynamic contact wire data. Then, the rise is calculated by manually matching the static and dynamic contact wire data. This method cannot continuously measure the rise, can only measure at fixed points, and requires a lot of manpower. The efficiency and accuracy of determining the contact wire rise are low. Summary of the Invention

The method includes:

[0006] When the high-speed railway inspection vehicle is running on a designated railway line, it acquires dynamic contact wire data detected by dynamic measurement components installed on the high-speed railway inspection vehicle.

[0007] Dynamic contact wire data is input into a pre-trained feature recognition model to determine the first anchor section information and the first fixed support information of the contact network of a specified railway line. The feature recognition model is obtained by training a neural network model based on historical contact wire data of various types of railway line contact networks and historical anchor section information and historical fixed support information of each railway line contact network.

[0008] The information of the first anchor section and the information of the first fixed support are matched with the information of the second anchor section and the information of the second fixed support of the catenary of the designated railway line, which are determined in advance based on the static contact wire data, to determine the first matching result. The static contact wire data is the contact wire data obtained when there are no vehicles running on the designated railway line.

[0009] Based on the first matching result, determine the dynamic contact line data and static contact line data at the same location;

[0010] The dynamic lifting amount of the contact wire is determined based on the dynamic and static contact wire data at the same location.

[0013] The identification module is used to input dynamic contact wire data into a pre-trained feature identification model to determine the first anchor section information and the first fixed support information of the contact network of a specified railway line.

[0014] The first matching module is used to match the information of the first anchor section and the information of the first fixed support with the information of the second anchor section and the information of the second fixed support of the catenary of a specified railway line, which are determined in advance based on the static contact wire data, and to determine the first matching result.

[0015] The data alignment module is used to determine the dynamic contact line data and static contact line data at the same position based on the first matching result;

[0016] The lifting amount determination module is used to determine the dynamic lifting amount of the contact wire based on dynamic contact wire data and static contact wire data at the same location.

[0017] This invention also provides a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the above-mentioned method for determining the dynamic lifting amount of the contact line.

[0019] This invention also provides a computer program product, which includes a computer program that, when executed by a processor, implements the above-mentioned method for determining the dynamic lifting amount of the contact line.

[0020] In this embodiment of the invention, when a high-speed railway inspection vehicle is running on a designated railway line, dynamic contact line data detected by a dynamic measurement component installed on the high-speed railway inspection vehicle is acquired. The dynamic contact line data is input into a pre-trained feature recognition model to determine the first anchor section information and the first fixed support information of the contact network of the designated railway line. The feature recognition model is trained on a neural network model based on historical contact line data of various types of railway line contact networks and historical anchor section and fixed support information of each railway line contact network. The first anchor section information and the first fixed support information are matched with the second anchor section information and the second fixed support information of the contact network of the designated railway line, which are pre-determined based on static contact line data, to determine a first matching result. The static contact line data is the contact line data acquired when no vehicles are running on the designated railway line. Based on the first matching result, dynamic contact line data and static contact line data at the same location are determined. Based on the dynamic contact line data and static contact line data at the same location, the dynamic lifting amount of the contact line is determined. In this way, the dynamic measurement component can continuously detect dynamic contact wire data. Through the feature recognition model, it can quickly determine the first anchor section information and the first fixed support information of the contact wire of a specified railway line based on the dynamic contact wire data. The first anchor section information and the first fixed support information are matched with the second anchor section information and the second fixed support information of the pre-acquired static contact wire data. Based on the matching result, the dynamic contact wire data and static contact wire data at the same position can be quickly and accurately determined, that is, the dynamic contact wire data and static contact wire data are aligned, and then the continuous dynamic rise of the contact wire can be determined. This process does not require a lot of manpower, which can improve the measurement efficiency of the contact wire rise and reduce the consumption of manpower. Moreover, since the anchor section information and the fixed support information are fixed equipment of the contact wire, the data alignment of the dynamic contact wire data and the static contact wire data based on the anchor section information and the fixed support information, and then the dynamic rise of the contact wire, can improve the accuracy of determining the contact wire rise.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0030] In the description of this specification, the terms "comprising," "including," "having," and "containing" are open-ended terms, meaning that they include but are not limited to. The terms "an embodiment," "a specific embodiment," "some embodiments," and "for example," etc., refer to specific features, structures, or characteristics described in connection with that embodiment or example that are included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, or characteristics described can be combined in any suitable manner in one or more embodiments or examples. The order of steps involved in the various embodiments is used to illustrate the implementation of this application, and the order of steps is not limited and can be adjusted appropriately as needed.

[0031] Terminology Explanation:

[0032] Anchor section: refers to a series of independent segments in the catenary, which are divided according to power supply and mechanical requirements, within the catenary section or station area.

[0033] Fixed supports: These are multiple supports deployed at fixed intervals on the overhead contact line to bear the full load of the contact suspension, support, and positioning devices, and to fix the contact suspension at a specified position and height.

[0034] Research has found that the existing methods for determining the contact wire rise mainly involve using measuring equipment (such as contact sensor measurement, non-contact image measurement, etc.) fixed next to the line to detect static and dynamic contact wire data. Then, the rise is calculated by manually matching the static and dynamic contact wire data. This method cannot continuously measure the rise, can only measure at fixed points, and requires a lot of manpower. The efficiency and accuracy of determining the contact wire rise are low.

[0035] Therefore, embodiments of the present invention provide a method and apparatus for determining the dynamic lifting amount of the contact line to solve the problems existing in the above research.

[0036] like Figure 1 The diagram shows a flowchart of a method for determining the dynamic lifting amount of a contact line according to an embodiment of the present invention. This method may include the following steps:

[0037] Step 101: When the high-speed railway inspection vehicle is running on the designated railway line, acquire the dynamic contact wire data detected by the dynamic measurement components installed on the high-speed railway inspection vehicle.

[0038] Step 102: Input the dynamic contact wire data into the pre-trained feature recognition model to determine the first anchor section information and the first fixed support information of the contact network of the specified railway line. The feature recognition model is obtained by training a neural network model based on historical contact wire data of various types of railway line contact networks and historical anchor section information and historical fixed support information of each railway line contact network.

[0039] Step 103: Match the first anchor section information and the first fixed support information with the second anchor section information and the second fixed support information of the catenary of the designated railway line, which are determined in advance based on the static contact wire data, and determine the first matching result. The static contact wire data is the contact wire data obtained when there are no vehicles running on the designated railway line.

[0040] Step 104: Determine the dynamic contact line data and static contact line data at the same position based on the first matching result;

[0041] Step 105: Determine the dynamic lifting amount of the contact wire based on the dynamic contact wire data and static contact wire data at the same location.

[0042] In this embodiment of the invention, when a high-speed railway inspection vehicle is running on a designated railway line, dynamic contact line data detected by a dynamic measurement component installed on the high-speed railway inspection vehicle is acquired. The dynamic contact line data is input into a pre-trained feature recognition model to determine the first anchor section information and the first fixed support information of the contact network of the designated railway line. The feature recognition model is trained on a neural network model based on historical contact line data of various types of railway line contact networks and historical anchor section and fixed support information of each railway line contact network. The first anchor section information and the first fixed support information are matched with the second anchor section information and the second fixed support information of the contact network of the designated railway line, which are pre-determined based on static contact line data, to determine a first matching result. The static contact line data is the contact line data acquired when no vehicles are running on the designated railway line. Based on the first matching result, dynamic contact line data and static contact line data at the same location are determined. Based on the dynamic contact line data and static contact line data at the same location, the dynamic lifting amount of the contact line is determined. In this way, the dynamic measurement component can continuously detect dynamic contact wire data. Through the feature recognition model, it can quickly determine the first anchor section information and the first fixed support information of the contact wire of a specified railway line based on the dynamic contact wire data. The first anchor section information and the first fixed support information are matched with the second anchor section information and the second fixed support information of the pre-acquired static contact wire data. Based on the matching result, the dynamic contact wire data and static contact wire data at the same position can be quickly and accurately determined, that is, the dynamic contact wire data and static contact wire data are aligned, and then the continuous dynamic rise of the contact wire can be determined. This process does not require a lot of manpower, which can improve the measurement efficiency of the contact wire rise and reduce the consumption of manpower. Moreover, since the anchor section information and the fixed support information are fixed equipment of the contact wire, the data alignment of the dynamic contact wire data and the static contact wire data based on the anchor section information and the fixed support information, and then the dynamic rise of the contact wire, can improve the accuracy of determining the contact wire rise.

[0043] It should be noted that, in this embodiment of the invention, in order to improve system operating efficiency, before measuring the dynamic rise of the contact wire of the specified railway line's catenary, it is necessary to obtain the static contact wire data of the catenary in advance. The static contact wire data is obtained when no vehicles are running on the specified railway line. In this embodiment of the invention, the static contact wire data may include second guide height data and second pull-out value data.

[0044] In practice, after obtaining the static contact line data, it is necessary to preprocess the static contact line data. Preprocessing may include filtering abnormal data, identifying anchor section information and fixed support information.

[0045] Filtering outlier data can be handled in the following ways:

[0046] Spatial distance L between sampling points of static contact wire data ij (millimeters) should satisfy the following formula:

[0047]

[0048] Among them, L ij : The distance from the i-th sampling point to the j-th sampling point.

[0049] s i : The value pulled out at the i-th sampling point.

[0050] h i : Guide height of the i-th sampling point.

[0051] s j : The pull-out value of the j-th sampling point.

[0052] h j : Guide height of the j-th sampling point.

[0053] Set up a 5-meter (can be set according to actual situation) clean data queue. Each data has a follow-distance pointer member, which records the pointer of the data with the smallest distance to the non-cleaned data in the queue in the spatial distance calculation of the subsequent data. If there are multiple, only the first one is recorded. That is, if the follow-distance pointer is not empty, the variable is not updated. This is because subsequent operations will group the data according to whether the follow-distance pointer of the data is the next consecutive data. After multiple data have the smallest proximity relationship, the second and subsequent data will naturally be divided into different data groups.

[0054] During initialization, 20 sampled data (which can be set according to actual conditions) are entered into the cleaning queue, and their follow-up pointers are set to the next nearest data in sequence. The clearing mark is set to invalid, thus ensuring that the initialized data are all normal data.

[0055] When new data to be cleaned enters the cleaning queue, the distance between the new data and other data in the queue (excluding data whose clearing mark is valid) is calculated in turn. The distance pointer after the data with the smallest distance is checked to see if it is null. If it is null, the pointer of the data to be cleaned is assigned to the distance pointer variable after the data with the smallest distance. Otherwise, no operation is performed.

[0056] Check the continuity between the tail data and the next tail data in the cleaning queue (whether the data pointed to by the follow pointer is the nearest subsequent data). If they do not meet the continuity requirement, check the number of data groups N in the queue and the number of members C of the data group Bn containing the next tail data, and determine the following two conditions:

[0057] N≥4 and the data set Bn is not in the first half;

[0058] N≤3 and C≤5;

[0059] If any of the above conditions are met, data group Bn is cleared (the clearing flag for all data in Bn is set to valid).

[0060] The data at the tail of the queue is removed from the queue and transferred to the subsequent data processing buffer.

[0061] The data to be cleaned is queued.

[0062] After testing the line data, the above method successfully removed scattered abnormal data. The cleaned static contact wire data is as follows: Figure 2 As shown, where, Figure 2 The circled area represents abnormal data.

[0063] In practice, the information on anchor sections and fixed supports can be identified by inputting static contact wire data into a pre-trained feature recognition model, and the information on the second anchor section and the second fixed support of the contact wire of a specified railway line can be determined based on the static contact wire data.

[0064] Among them, the feature recognition model uses deep neural network technology to identify the anchor sections and fixed supports of the catenary corresponding to the contact wire data.

[0065] The following is a brief introduction to neural network models:

[0066] The neural network model consists of many interconnected neurons, and the operational formula for each neuron is shown below:

[0067]

[0068] Among them, y j Let f(x) be the output of the j-th neuron, and f(x) be the activation function (common activation functions include the sigmoid function, linear correction function, tanh(x) function, etc.). i For the input signal, w ij Let b be the coefficient of the i-th input of the j-th neuron. j This represents the offset of a neuron. When multiple units are combined and have a hierarchical structure, an artificial neural network model is formed, which is a deep learning network.

[0069] The main structure of a neural network model consists of convolutional layers, fully connected layers, and an output layer. The convolutional layers contain a large number of neurons that interact only with some neighboring neurons. Each convolutional layer contains multiple feature planes, and each feature plane is a set of related neurons. The weights of all neurons in a feature plane are the same set, which constitutes the convolutional kernel. In this embodiment, the convolutional kernel is initialized using pre-trained deep learning network parameters. Combined with its own training data, the convolutional kernel gradually approaches the true value during continuous training and learning. The fully connected layers mainly perform feature space transformations of matrices and vectors. The ultimate goal of these space transformations is to complete subsequent classification, so fully connected layers generally appear in the later layers of the network. The output layer implements the function of a classifier, typically using Logical Regression, Softmax Regression, or Support Vector Machines for classification.

[0070] Specifically, the neural network model in this embodiment of the invention is based on the SSD (single-shot multibox detector) network structure and has been optimized and adjusted. This network structure simultaneously achieves detection and classification, enabling end-to-end integrated training and object detection. The neural network model in this embodiment can transform feature maps into result sets of multiple scales and proportions. During prediction, the network scores each existing category corresponding to the candidate result and improves the candidate result accordingly to more accurately match the shape of the object to be identified. Moreover, the network combines feature maps of different specifications to enhance its multi-scale detection performance. The network model is a single-shot detector applicable to multiple classifications, faster than previous single-shot detectors without sacrificing accuracy. This method uses small convolutional kernels on the feature maps, enhancing the expressive power of the detected object's features.

[0071] In this embodiment of the invention, a feature recognition model can be obtained by training a neural network model based on historical contact wire data of various types of railway contact networks and historical anchor section information and historical fixed support information of each railway contact network.

[0072] In this way, by inputting static contact wire data into a pre-trained feature recognition model, the information of the second anchor section and the second fixed support of the contact wire of a specified railway line can be determined based on the static contact wire data.

[0073] It should also be noted that, in this embodiment of the invention, a dynamic measurement component needs to be installed on the high-speed railway inspection vehicle to detect the dynamic contact wire data of the overhead contact system during the operation of the high-speed railway inspection vehicle. The dynamic measurement component can be installed at the pantograph position of the high-speed railway inspection vehicle.

[0074] The following is about Figure 1 The method for determining the dynamic lifting amount of the contact line is explained in detail.

[0075] In step 101 above, dynamic contact wire data can be detected by a dynamic measurement component installed on the high-speed railway inspection vehicle when the vehicle is running on a designated railway line.

[0076] The dynamic contact wire data may include the first guide height data and the first pull-out value data.

[0077] In practice, after obtaining the dynamic contact line data, abnormal data can be filtered out. The specific filtering method can be referred to the above method for filtering abnormal data in static contact line data, and will not be elaborated further here.

[0078] In step 102 above, dynamic contact wire data can be input into the trained feature recognition model to determine the first anchor section information and the first fixed support information of the contact wire of a specified railway line.

[0079] In this embodiment of the invention, to improve operating efficiency, before inputting the dynamic contact line data into the trained feature recognition model, the following may also be included:

[0080] The first guide height data is converted into dynamic guide height waveform data; the first pull-out value data is converted into dynamic pull-out value waveform data.

[0081] Step 102 above may specifically include:

[0082] The dynamic guide height waveform data and the dynamic pull-out value waveform data are input into a pre-trained feature recognition model to determine the first anchor section information and the first fixed support information of the catenary of a specified railway line.

[0083] In step 103 above, the information of the first anchor section and the information of the first fixed support can be matched with the information of the second anchor section and the information of the second fixed support of the contact network of the designated railway line, which are determined in advance based on the static contact wire data, to determine the first matching result.

[0084] In practice, step 103 above is a feature alignment process, which aligns the information of the first anchor segment with the information of the second anchor segment, and aligns the information of the first fixed support with the information of the second fixed support.

[0085] To improve the efficiency of feature alignment, the aforementioned dynamic contact wire data also includes first mileage data; the aforementioned static contact wire data also includes second mileage data; therefore, before matching the first anchor segment information and the first fixed support information with the second anchor segment information and the second fixed support information of the designated railway line contact network pre-determined based on the static contact wire data to obtain the first matching result, the following may also be included:

[0086] Based on the first mileage data and the second mileage data, the first guide height data is matched with the second guide height data, and the first pull-out value data is matched with the second pull-out value data to obtain the second matching result;

[0087] Step 103 above may specifically include:

[0088] Based on the second matching result, the information of the first anchor section and the information of the first fixed support are matched with the information of the second anchor section and the information of the second fixed support of the overhead contact system of the designated railway line, which are determined in advance based on the static contact wire data, to determine the first matching result.

[0089] In this way, by first performing a coarse match between the dynamic and static contact wire data using mileage data, and then matching the information of the first anchor section and the first fixed support with the information of the second anchor section and the second fixed support of the contact network of the specified railway line determined in advance based on the static contact wire data, the efficiency of feature alignment can be improved, thereby improving the efficiency of determining the dynamic lifting amount.

[0090] In embodiments of the present invention, such as Figure 3 As shown, the information of the first anchor section and the information of the first fixed support are matched with the information of the second anchor section and the information of the second fixed support of the overhead contact system of a designated railway line, which are determined in advance based on static contact wire data, to obtain the first matching result. Specifically, this may include the following steps:

[0091] Step 301: Match the information of the first anchor segment with the information of the second anchor segment one by one to obtain matching data pairs of the information of the first anchor segment and the information of the second anchor segment;

[0092] Step 302: Based on the matching data pair of the first anchor segment information and the second anchor segment information, the first fixed support information and the second fixed support information, verify the consistency between the number of first fixed support information between two adjacent first anchor segments and the number of second fixed support information between two adjacent second anchor segments.

[0093] Step 303: If they match, match each first fixed pillar information between two adjacent first anchor segments with each second fixed pillar information between two adjacent second anchor segments to obtain matching data pairs of first fixed pillar information and second fixed pillar information.

[0094] Step 304: If there is a discrepancy, then based on the position of each first fixed support information between two adjacent first anchor segments in the dynamic contact line data between the two adjacent first anchor segments, and the position of each second fixed support information between two adjacent second anchor segments in the static contact line data between the two adjacent second anchor segments, match each first fixed support information between two adjacent first anchor segments with each second fixed support information between two adjacent second anchor segments to obtain a matching data pair of first fixed support information and second fixed support information.

[0095] Step 305: The matching data pairs of the first anchor segment information and the second anchor segment information, and the matching data pairs of the first fixed support information and the second fixed support information are determined as the first matching result.

[0096] In specific implementation, in step 301, the first anchor segment information and the second anchor segment information that are close in distance (i.e., the mileage error meets the preset error value) can be matched according to the mileage data corresponding to the first anchor segment information and the second anchor segment information to obtain the matching data pair of the first anchor segment information and the second anchor segment information.

[0097] In specific implementation, in step 302, based on the matching data pairs of the first anchor segment information and the second anchor segment information, the number of first fixed support information between two adjacent first anchor segments and the number of second fixed support information between two adjacent second anchor segments belonging to the same matching data pair can be determined, and it can be verified whether the numbers are consistent. If they are consistent, then step 303 is executed; if they are inconsistent, then step 304 is executed.

[0098] In specific implementation, in step 303, if they match, each first fixed pillar information between two adjacent first anchor segments is matched one by one with each second fixed pillar information between two adjacent second anchor segments. The matching method can also be based on the mileage data corresponding to each first fixed pillar information and the mileage data corresponding to each second fixed pillar information. First fixed pillar information and second fixed pillar information that are close in distance (i.e., the mileage error meets the preset error value) are matched to obtain a matching data pair of first fixed pillar information and second fixed pillar information.

[0099] In specific implementation, in step 304, if there is a discrepancy, then based on the position of each first fixed support information between two adjacent first anchor segments in the dynamic contact line data between the two adjacent first anchor segments, and the position of each second fixed support information between two adjacent second anchor segments in the static contact line data between the two adjacent second anchor segments, each first fixed support information between two adjacent first anchor segments is matched one by one with each second fixed support information between two adjacent second anchor segments to obtain a matching data pair of first fixed support information and second fixed support information.

[0100] In this embodiment of the invention, step 304 may specifically include:

[0101] Calculate the ratio of the number of dynamic contact line data contained from the position of each first fixed support information between two adjacent first anchor segments to the total number of dynamic contact line data between two adjacent first anchor segments, and record it as the first ratio data; calculate the ratio of the number of static contact line data contained from the position of each second fixed support information between two adjacent second anchor segments to the total number of static contact line data between two adjacent second anchor segments, and record it as the second ratio data;

[0102] If the absolute value of the difference between the first ratio data and the second ratio data meets the preset value, then the first fixed support information between two adjacent first anchor segments is matched with the second fixed support information between two adjacent second anchor segments to obtain a matching data pair of the first fixed support information and the second fixed support information.

[0103] If the absolute value of the difference between the first ratio data and the second ratio data does not meet the preset value, then based on whether the dynamic contact line data of the position of the first fixed support information between two adjacent first anchor segments is an extreme point, if yes, the first fixed support information is retained; if no, the first fixed support information is deleted. Based on whether the static contact line data of the position of the second fixed support information between two adjacent second anchor segments is an extreme point, if yes, the second fixed support information is retained; if no, the second fixed support information is deleted. After retaining or deleting the first and second fixed support information, the consistency between the number of first fixed support information between two adjacent first anchor segments and the number of second fixed support information between two adjacent second anchor segments is rechecked.

[0104] In practice, for example, Figure 4 This refers to the information on the first anchor section of the overhead contact system for a designated railway line, determined based on dynamic contact wire data. Figure 4 The circled portion represents information about two adjacent first anchor segments. Figure 5 The second anchor section information of the catenary of a specified railway line determined according to the static contact wire data Figure 5 The circled part in it is the information of two adjacent second anchor sections. According to Figure 4 and Figure 5 it can be known that the number of the first fixed supports between two adjacent first anchor section information is 35, and the number of the second fixed supports between two adjacent second anchor section information is 33, and the numbers are inconsistent. The method for executing step 304 includes:

[0105] Taking Figure 4 two adjacent first anchor section information in it as a matching section, and taking Figure 5 two adjacent second anchor section information in it as a matching section.

[0106] Within the matching section of Figure 4 , the total length of the section is sd (that is, it can be understood that the total number of dynamic contact wire data of the matching section is sd), the length of the first first fixed support is sd1 (that is, it can be understood that the number of dynamic contact wire data included from the position of the first first fixed support in the matching section to the starting position is sd1), and the first ratio data is rd1 = sd1 / sd.

[0107] Within the matching section of Figure 5 , the total length of the section is sj (that is, it can be understood that the total number of static contact wire data of the matching section is sj), the length of the first second fixed support is sj1 (that is, it can be understood that the number of static contact wire data included from the position of the first second fixed support in the matching section to the starting position is sj1), and the second ratio data is rj1 = sj1 / sj.

[0108] If |rd1 - rj1| < t, it is considered that the first fixed support information and the second fixed support information match; otherwise, it is considered that the first fixed support information or the second fixed support information is a fixed support to be deleted, that is, it is necessary to judge whether the first fixed support information or the second fixed support information is to be deleted or retained.

[0109] In specific implementation, it can be judged whether the first fixed support information or the second fixed support information is to be deleted or retained according to whether the contact wire data at the position of the fixed support between two adjacent anchor section information is an extreme point. For example, verify whether the contact wire data at the position of the fixed support to be deleted is an extreme point of the data within a preset distance range. If so, retain it; otherwise, delete it. Then, after retaining or deleting the first fixed support information and the second fixed support information, re-verify the consistency of the number of the first fixed support information between two adjacent first anchor section information and the number of the second fixed support information between two adjacent second anchor section information.

[0110] In specific implementation, in step 305, the matching data pairs of the first anchor segment information and the second anchor segment information, and the matching data pairs of the first fixed support information and the second fixed support information can be determined as the first matching result.

[0111] In step 104 above, dynamic contact line data and static contact line data at the same position can be determined based on the first matching result.

[0112] In practice, step 104 is the process of aligning the dynamic contact wire data with the static contact wire data.

[0113] In this embodiment of the invention, step 104 may specifically include:

[0114] Based on the matching data pairs of the first anchor segment information and the second anchor segment information, and the matching data pairs of the first fixed support information and the second fixed support information, the dynamic contact line data and static contact line data at the same position are determined.

[0115] In this embodiment of the invention, based on the matching data pairs of the first anchor segment information and the second anchor segment information, and the matching data pairs of the first fixed support information and the second fixed support information, the dynamic contact line data and static contact line data at the same position are determined, which may specifically include:

[0116] Based on the matching data pairs of the first anchor segment information and the second anchor segment information, and the matching data pairs of the first fixed support information and the second fixed support information, determine the dynamic contact line data between two adjacent first anchor segments and two adjacent first fixed support information, and the static contact line data between two adjacent second anchor segments and two adjacent second fixed support information.

[0117] Based on the dynamic contact line data between two adjacent first fixed support information and between two adjacent first anchor segments, the static contact line data at the same location is determined from the static contact line data between two adjacent second fixed support information and between two adjacent second anchor segments using linear interpolation.

[0118] In practice, after obtaining the matching data pairs of the first anchor segment information and the second anchor segment information, as well as the matching data pairs of the first fixed support information and the second fixed support information, data alignment within the fixed supports can be performed. Using the dynamic contact line data between the fixed supports as a benchmark, the static contact line data at the same location is determined from the static contact line data using linear interpolation.

[0119] For example, the dynamic contact wire dataset is {dh|dh1~dhn}, and the static contact wire dataset is {jh|jh1~jhm};

[0120] The following formula is used to determine the jh corresponding to dhi:

[0121]

[0122] The jh corresponding to dhi is (jh) tl +jh th ) / 2.

[0123] In step 105 above, the dynamic lifting amount of the contact wire can be determined based on the dynamic contact wire data and the static contact wire data at the same location.

[0124] In this embodiment of the invention, step 105 may specifically include:

[0125] Calculate the difference between the first guide height data in the dynamic contact wire data and the second guide height data in the static contact wire data at the same location, and determine the dynamic lifting amount of the contact wire as the difference between the first guide height data in the dynamic contact wire data and the second guide height data in the static contact wire data at the same location.

[0126] For example, the dynamic lift of the contact wire can be calculated using the following formula:

[0127] H uplift =H dynamic -H static

[0128] In the above formula:

[0129] H uplift This refers to the dynamic lifting amount of the contact wire;

[0130] H dynamic This is the dynamic guide height value (first guide height data);

[0131] H static This is the static guide height value (second guide height data).

[0132] In this way, the dynamic measurement component can continuously detect dynamic contact wire data using the above method. The feature recognition model can quickly determine the first anchor section and first fixed support information of the contact wire for a specified railway line based on the dynamic contact wire data. The first anchor section and first fixed support information are then matched with the second anchor section and second fixed support information from pre-acquired static contact wire data. Based on the matching results, the dynamic and static contact wire data at the same location can be quickly and accurately determined, i.e., data alignment is performed between the dynamic and static contact wire data. This allows for the determination of the continuous dynamic rise of the contact wire. This process does not require a large amount of manpower, improving the efficiency of contact wire rise measurement and reducing manpower consumption. Furthermore, since the anchor section and fixed support information are fixed components of the contact wire, data alignment between the dynamic and static contact wire data based on these information, and thus the determination of the dynamic rise of the contact wire, can improve the accuracy of determining the contact wire rise.

[0133] This invention also provides a device for determining the dynamic lifting amount of the contact wire, as described in the following embodiments. Since the principle by which this device solves the problem is similar to the method for determining the dynamic lifting amount of the contact wire, the implementation of this device can refer to the implementation of the method for determining the dynamic lifting amount of the contact wire; repeated details will not be elaborated further.

[0145] In this embodiment of the invention, the dynamic contact wire data may further include first mileage data; the static contact wire data may further include second mileage data.

[0146] The device may further include a second matching module, used before the first matching module matches the first anchor section information and the first fixed support information with the second anchor section information and the second fixed support information of the specified railway line catenary, which are pre-determined based on static contact wire data, to obtain a first matching result:

[0148] The first matching module can be used specifically for:

[0153] If they match, match each first fixed pillar information between two adjacent first anchor segments with each second fixed pillar information between two adjacent second anchor segments to obtain matching data pairs of first fixed pillar information and second fixed pillar information.

[0154] If there is a discrepancy, then based on the position of each first fixed support information between two adjacent first anchor segments in the dynamic contact line data between the two adjacent first anchor segments, and the position of each second fixed support information between two adjacent second anchor segments in the static contact line data between the two adjacent second anchor segments, each first fixed support information between two adjacent first anchor segments and each second fixed support information between two adjacent second anchor segments are matched one by one to obtain a matching data pair of first fixed support information and second fixed support information;

[0155] The matching data pairs of the first anchor segment information and the second anchor segment information, and the matching data pairs of the first fixed support information and the second fixed support information are determined as the first matching result.

[0156] In this embodiment of the invention, the first matching module can also be used for:

[0158] If the absolute value of the difference between the first ratio data and the second ratio data meets the preset value, then the first fixed support information between two adjacent first anchor segments is matched with the second fixed support information between two adjacent second anchor segments to obtain a matching data pair of the first fixed support information and the second fixed support information.

[0159] If the absolute value of the difference between the first ratio data and the second ratio data does not meet the preset value, then based on whether the dynamic contact line data of the position of the first fixed support information between two adjacent first anchor segments is an extreme point, if yes, the first fixed support information is retained; if no, the first fixed support information is deleted. Based on whether the static contact line data of the position of the second fixed support information between two adjacent second anchor segments is an extreme point, if yes, the second fixed support information is retained; if no, the second fixed support information is deleted.
