Abstract
Description
Technical Field
[0001] This invention relates to the field of rail transit technology, specifically to a method, apparatus, electronic device, and storage medium for handling interference between adjacent tracks. Background Technology
[0002] Currently, the commonly used train positioning and speed measurement technologies in urban rail transit involve measuring speed using train speed sensors and using ground transponders for position correction to achieve train position detection, speed detection, and train direction determination. Through research and communication, it has been found that grating array sensing technology can sense the changing patterns of external vibration signals. To further explore the application of grating array sensing technology in rail transit signaling systems, and considering its application in urban rail train positioning and speed measurement, a new trackside train position detection device needs to be developed—the grating array intelligent train sensing system (hereinafter referred to as the "intelligent train sensing system"). This system uses grating array sensing optical cables to acquire and process the vibration information generated by the train traveling on the track, enabling the positioning and tracking of trains on the line, and achieving detection of train position, speed, direction of travel, and integrity.
[0003] The intelligent train sensing system is a signaling device that uses grating array sensing technology to collect and process trackside vibration information, locate and track wheel-rail trains on the track, detect the occupancy of grating measurement areas (referred to as "measurement areas"), and ultimately detect the train's position, speed, direction of travel, and integrity. Structurally, it consists of an intelligent sensing host (referred to as "host") and an intelligent sensing demodulator (referred to as "demodulator"). The demodulator includes a grating array sensing optical cable (referred to as "optical cable") and detection circuitry. The demodulator's main function is to collect vibration information generated by the train traveling on the track, process the vibration information, calculate the occupancy status information of each measurement area, and send it to the host. The host's main function is to receive the occupancy status information of each measurement area sent by the demodulator and calculate information such as the train's position and speed.
[0004] Since the information source of the train intelligent sensing system is vibration information, it is necessary to accurately distinguish the vibration information generated by the train traveling on the track from other vibration information to avoid interference from other vibration information that could affect the calculation of train position, speed, and other information. Because grating array sensing technology has high sensitivity to vibration detection, many factors in rail transit can cause interference, such as objects falling from the trackside, vehicles running above subway tunnels, and loud noises nearby. Among these, vibration interference caused by trains running on adjacent tracks (referred to as "adjacent track interference") requires special attention because the vibration signals caused by this type of interference are highly similar to the vibrations of trains running normally on the same line, making it easier for the system to misjudge. Therefore, a solution needs to be developed to address adjacent track interference. Summary of the Invention
[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a method, device, electronic device and storage medium for handling interference between adjacent tracks, thereby solving the problem that in the prior art, when using grating array sensing technology to detect train vibration, it is impossible to avoid and effectively distinguish and eliminate vibration interference caused by train operation on adjacent tracks.
[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:
[0007] In a first aspect, the present invention provides a method for handling interference between adjacent tracks, comprising:
[0008] Vibration data of a track vehicle collected by a grating array is acquired, and the vibration data is filtered according to the energy calculation results of the vibration data to obtain target vibration data.
[0009] Based on the location information obtained from the target vibration data, the train-occupied area is determined, and based on the train-occupied area, the target vibration data is compared with preset train-occupied area data to determine the adjacent line interference situation in the target vibration data.
[0010] Based on the interference from adjacent lines, track vehicle tracking management is implemented.
[0011] In some embodiments, filtering the vibration data based on the energy calculation results of the vibration data to obtain target vibration data includes:
[0012] Obtain the amplitude information of the vibration data;
[0013] The amplitude energy threshold is determined based on the influence of train weight, train speed, track bed conditions, and distance from the vibration source on the amplitude.
[0014] Based on the relationship between the amplitude energy calculation result corresponding to the vibration data and the amplitude energy threshold, the vibration data is filtered to obtain the target vibration data.
[0015] In some embodiments, filtering the vibration data based on the relationship between the amplitude energy calculation result corresponding to the vibration data and the amplitude energy threshold to obtain target vibration data includes:
[0016] If the calculated amplitude energy corresponding to the vibration data is not less than the amplitude energy threshold, then the vibration data is determined to be the target vibration data.
[0017] In some embodiments, determining the train-occupied area based on the location information obtained from the target vibration data includes:
[0018] Based on the target vibration data, the relationship between the location information and the entrance of the grating array's jurisdiction is obtained to determine the area occupied by the train.
[0019] In some embodiments, the step of comparing the target vibration data with preset train occupancy area data to determine the adjacent track interference situation in the target vibration data includes:
[0020] If the area occupied by the train is occupied for the first time, it is determined whether the area occupied by the train is the entrance to the jurisdiction of the grating array. If it is not the entrance to the jurisdiction of the grating array, the target vibration data is determined to be adjacent line interference.
[0021] If the area occupied by the train is an existing train-occupied area, then the consistency between the train speed and the amplitude of the area occupied by the train is determined. If the train speed and the amplitude of the area occupied by the train are inconsistent, then the target vibration data is determined to be adjacent line interference.
[0022] In some embodiments, the tracking management of track vehicles based on the adjacent track interference includes:
[0023] Based on the adjacent line interference situation, determine the type of the occupied area corresponding to the adjacent line interference;
[0024] Based on the type of area occupied by the adjacent line interference, the adjacent line interference is tracked and managed.
[0025] In some embodiments, the types of adjacent line interference occupied areas include: occupied areas smaller than the train length; occupied areas containing multiple occupied sub-areas; multiple adjacent line interference occupied areas with a distance less than a threshold; and adjacent line interference and non-adjacent line interference occupied areas with a distance less than a threshold. Determining the type of occupied area corresponding to the adjacent line interference based on the adjacent line interference situation includes:
[0026] When the adjacent line interference occupancy area type is the first occupancy type, the occupancy area is determined to be a non-train occupancy area, and the first occupancy type is that the occupancy area is less than the train length;
[0027] When the adjacent line interference occupancy area type is the second occupancy type, it is determined that the multiple occupancy sub-regions are all adjacent line interference occupancy areas, and the second occupancy type is an occupancy area containing multiple occupancy sub-regions;
[0028] When the adjacent line interference occupancy area type is the third occupancy type, the multiple adjacent line interference occupancy areas are merged into the same adjacent line interference occupancy area. The third occupancy type is when the distance between multiple adjacent line interference occupancy areas is less than a threshold.
[0029] When the adjacent line interference occupancy area type is the fourth occupancy type, the adjacent line interference occupancy area and the non-adjacent line interference occupancy area are merged into the same train occupancy area. The fourth occupancy type is when the distance between the adjacent line interference and the non-adjacent line interference occupancy areas is less than a threshold.
[0030] Secondly, the present invention also provides a track adjacent line interference processing device, comprising:
[0031] The acquisition module is used to acquire vibration data of a track vehicle based on a grating array, and filter the vibration data according to the energy calculation results of the vibration data to obtain target vibration data.

[0034] Thirdly, the present invention also provides an electronic device, comprising: a processor and a memory;
[0035] The memory stores a computer-readable program that can be executed by the processor;
[0036] When the processor executes the computer-readable program, it implements the steps in the track adjacent line interference processing method as described above.
[0037] Fourthly, the present invention also provides a computer-readable storage medium storing one or more programs that can be executed by one or more processors to implement the steps in the track adjacent line interference processing method described above.
[0038] Compared with existing technologies, the track adjacent line interference processing method, apparatus, electronic device, and storage medium provided by this invention first acquires vibration data of the track vehicle based on a grating array. Based on the energy calculation results of the vibration data, the vibration data is filtered to obtain target vibration data. This initial amplitude screening improves the effectiveness of the vibration data acquired by the grating array, thereby enhancing the accuracy of identifying adjacent line interference based on the grating array. Furthermore, based on the location information of the acquired target vibration data, the train-occupied area is determined. Based on the train-occupied area, the target vibration data is compared with preset train-occupied area data to determine the adjacent line interference in the target vibration data. Finally, based on the adjacent line interference, the track vehicle is tracked and managed. By comparing the vibration data of the train-occupied area with a preset threshold, adjacent line interference is further eliminated.

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0045] This invention provides a method for handling interference between adjacent tracks. Please refer to [link / reference]. Figure 1 ,include:
[0046] S101. Obtain vibration data of the track vehicle collected by a grating array, and filter the vibration data according to the energy calculation results of the vibration data to obtain target vibration data;
[0047] S102. Based on the location information obtained from the target vibration data, determine the train-occupied area, and based on the train-occupied area, compare the target vibration data with preset train-occupied area data to determine the adjacent line interference situation in the target vibration data.
[0048] S103. Based on the interference situation of adjacent lines, track vehicle tracking management is carried out.
[0049] In this embodiment, vibration data of the track vehicle based on a grating array is first acquired. Based on the energy calculation results of the vibration data, the vibration data is filtered to obtain target vibration data. This initial amplitude filtering improves the effectiveness of the vibration data acquired by the grating array, thereby enhancing the accuracy of identifying adjacent track interference based on the grating array. Furthermore, based on the location information of the acquired target vibration data, the train-occupied area is determined. Based on the train-occupied area, the target vibration data is compared with preset train-occupied area data to determine adjacent track interference within the target vibration data. Finally, based on the adjacent track interference, the track vehicle is tracked and managed. By comparing the vibration data of the train-occupied area with a preset threshold, adjacent track interference is further eliminated. The obtained adjacent track interference information is then used for track vehicle tracking and management to avoid adjacent track interference and system misjudgments, further improving the accuracy of the grating array in identifying adjacent track interference.
[0050] In step S101, the demodulator performs energy calculation on the acquired vibration signal and filters the calculation results to reduce the impact of interference from adjacent lines.
[0051] Furthermore, the demodulator processes the vibration information acquired through the grating array sensor network. The main characteristics of vibration information are amplitude and frequency. Through modeling analysis and testing, the amplitude and frequency range of the vibration information generated by train operation can be obtained. The purpose of the demodulator is to acquire vibration information with amplitude and frequency within predetermined ranges.
[0052] In some embodiments, please refer to Figure 2 The step of filtering the vibration data based on the energy calculation results of the vibration data to obtain the target vibration data includes:
[0053] S201. Obtain the amplitude information of the vibration data;
[0054] S202. Determine the amplitude energy threshold based on the influence of train weight, train speed, track bed conditions, and distance from the vibration source on the amplitude.
[0055] S203. Based on the relationship between the amplitude energy calculation result corresponding to the vibration data and the amplitude energy threshold, the vibration data is filtered to obtain the target vibration data.
[0056] In this embodiment, the demodulator processes vibration frequency mainly by filtering the frequency. Since the vibration frequency is mainly determined by the object that causes the vibration, the frequency of the vibration information generated by the adjacent line interference and the train running on this line may be very close, making it difficult to filter by the filtering algorithm. Therefore, the demodulator processes the adjacent line interference mainly by processing the amplitude.
[0057] Furthermore, the demodulator processes amplitude primarily by calculating vibration energy. Modeling analysis and testing reveal that the vibration amplitude generated by train movement is mainly related to factors such as train weight, speed, track bed conditions, and distance from the vibration source. Analyzing these factors, it's clear that, due to the distance to the vibration source, under otherwise identical conditions, the vibration amplitude generated by trains traveling on adjacent lines is significantly smaller than that of trains on the same line. Therefore, after calculating the vibration energy, the demodulator filters the results and determines the validity of the vibration by comparing the vibration energy with a threshold, thus obtaining the target vibration data.
[0058] The setting of the vibration energy threshold should take into account the interference from adjacent lines. It should be noted that the higher the vibration energy threshold is set, the better it can eliminate the influence of interference from adjacent lines. However, since there are many factors affecting the amplitude, in specific engineering projects, it is difficult to guarantee that the amplitude of the trains running on this line is always less than the interference from adjacent lines. For example, the amplitude of a light train running at low speed on this line may be less than the interference amplitude of a heavy train running at high speed on an adjacent line. In order to ensure that the train information on this line is not lost, the vibration energy threshold should be set to ensure that the vibration energy of the trains running under the most unfavorable conditions is higher than the threshold. Therefore, this treatment can only eliminate some interference from adjacent lines.
[0059] In one specific embodiment, before the line is put into operation, the vibration energy of the trains operating under the most unfavorable conditions is obtained through field tests. The vibration energy of the train is related to the vibration amplitude caused by the train's movement; the smaller the amplitude, the smaller the vibration energy. The factors affecting the amplitude of vibration caused by train movement mainly include: train weight, running speed, and track conditions (ballast bed, rail condition, etc.). Among these, track conditions are inherent to the track and vary significantly across different areas. Therefore, the demodulator can set vibration energy thresholds for different test areas. Train weight and running speed affect the train's operation; the greater the weight and the faster the speed, the greater the vibration amplitude. Therefore, during the field tests, the train with the smallest weight among various models is selected, and the empty train is run at the lowest operable speed, with the entire line connected. The vibration energy in each test area is recorded during the connection process. Multiple tests are conducted, and the minimum vibration energy value from the multiple tests for each test area is taken. This value is the vibration energy of the trains operating under the most unfavorable conditions in that test area.
[0060] In some embodiments, filtering the vibration data based on the relationship between the amplitude energy calculation result corresponding to the vibration data and the amplitude energy threshold to obtain target vibration data includes:
[0061] If the calculated amplitude energy corresponding to the vibration data is not less than the amplitude energy threshold, then the vibration data is determined to be the target vibration data.
[0062] In this embodiment, if the vibration energy exceeds a threshold, the vibration information is considered valid; otherwise, it is considered interference. By judging the validity of vibration information based on the relationship between the amplitude energy threshold and the amplitude energy, preliminary judgment and screening of adjacent line interference information can be performed, improving the efficiency of adjacent line interference processing.
[0063] In some embodiments, determining the train-occupied area based on the location information obtained from the target vibration data includes:
[0064] Based on the target vibration data, the relationship between the location information and the entrance of the grating array's jurisdiction is obtained to determine the area occupied by the train.
[0065] In this embodiment, since the train exhibits different phenomena in existing occupied areas and newly occupied areas, the amplitude analysis of these areas also differs. Therefore, the host computer calculates and tracks the train's occupied area based on the amplitude information of each measurement zone sent by the demodulator to analyze whether there is adjacent track interference. Each measurement zone represents the monitoring area between two adjacent gratings.
[0066] In some embodiments, the step of comparing the target vibration data with preset train occupancy area data to determine the adjacent track interference situation in the target vibration data includes:
[0067] If the area occupied by the train is occupied for the first time, it is determined whether the area occupied by the train is the entrance to the jurisdiction of the grating array. If it is not the entrance to the jurisdiction of the grating array, the target vibration data is determined to be adjacent line interference.
[0068] If the area occupied by the train is an existing train-occupied area, then the consistency between the train speed and the amplitude of the area occupied by the train is determined. If the train speed and the amplitude of the area occupied by the train are inconsistent, then the target vibration data is determined to be adjacent line interference.
[0069] In this embodiment, it is first determined that under normal circumstances, the area occupied by a train should enter the equipment's jurisdiction from the line entrance. If the location where the train occupies the area for the first time is not the entrance to the equipment's jurisdiction, and the distance from the existing train occupies the area exceeds a threshold, the host determines that the train occupies the area due to adjacent line interference (hereinafter referred to as "adjacent line interference occupies the area"). Simultaneously, by adjusting the deployment of the grating array, it is ensured that adjacent line interference cannot occur at the entrance to the equipment's jurisdiction. Specifically, this can be achieved by deploying additional optical fibers outside the detection range to ensure that adjacent line interference does not occur at the entrance to the equipment's jurisdiction.
[0070] Furthermore, for areas occupied by existing trains, the host should calculate the train speed based on the changes in the location of the occupied area, and use the train speed to judge the amplitude of the measurement area within the occupied area. If the amplitude of the measurement area within the occupied area does not correspond to the train speed, the host determines that there is adjacent track interference in the occupied area.
[0071] In some embodiments, please refer to Figure 3 The tracking and management of track vehicles based on the adjacent line interference includes:
[0072] S301. Based on the adjacent line interference situation, determine the type of the occupied area corresponding to the adjacent line interference;
[0073] S302. Track and manage the interference of adjacent lines according to the type of area occupied by the interference of adjacent lines.
[0074] In this embodiment, based on the situation and cause of adjacent line interference, the type of occupied area corresponding to the adjacent line interference is determined, and the adjacent line interference is tracked and managed according to the type of occupied area, thereby avoiding the subsequent impact of adjacent line interference.
[0075] It should be noted that when the train stops, no more vibrations occur. Therefore, the train's intelligent sensing system needs to calculate the train's stopping position based on previous vibration information to determine whether adjacent track interference has occurred. Since the vibration intensity of a train traveling at low speed is relatively small, it may not be significantly different from adjacent track interference. Therefore, when the area occupied by the train stops and adjacent track interference is superimposed, the system cannot accurately determine whether the current vibration is adjacent track interference or a previously stopped train moving at low speed. Therefore, from a safety perspective, it must be assumed that the train may have moved.
[0076] Furthermore, once a potential train hiding area is identified, the measurement area within its range is always considered to be in a state of vibration, except for manual removal. That is, apart from manual removal, the potential train hiding area can only expand as the area moves, not shrink. When the distance between the potential train hiding area and other train-occupied areas (including adjacent track interference areas and non-adjacent track interference train-occupied areas) is less than a threshold, the main unit should merge the potential train hiding area with other train-occupied areas into a single train-occupied area; the new area remains a potential train hiding area. After a potential train hiding area appears, the train intelligent sensing system should issue an alarm, and the area should be manually removed by the operator.
[0077] In some embodiments, the types of adjacent line interference occupied areas include: occupied areas smaller than the train length; occupied areas containing multiple occupied sub-areas; multiple adjacent line interference occupied areas with a distance less than a threshold; and adjacent line interference and non-adjacent line interference occupied areas with a distance less than a threshold. Determining the type of occupied area corresponding to the adjacent line interference based on the adjacent line interference situation includes:
[0078] When the adjacent line interference occupancy area type is the first occupancy type, the occupancy area is determined to be a non-train occupancy area, and the first occupancy type is that the occupancy area is less than the train length;
[0079] When the adjacent line interference occupancy area type is the second occupancy type, it is determined that the multiple occupancy sub-regions are all adjacent line interference occupancy areas, and the second occupancy type is an occupancy area containing multiple occupancy sub-regions;
[0080] When the adjacent line interference occupancy area type is the third occupancy type, the multiple adjacent line interference occupancy areas are merged into the same adjacent line interference occupancy area. The third occupancy type is when the distance between multiple adjacent line interference occupancy areas is less than a threshold.
[0081] When the adjacent line interference occupancy area type is the fourth occupancy type, the adjacent line interference occupancy area and the non-adjacent line interference occupancy area are merged into the same train occupancy area. The fourth occupancy type is when the distance between the adjacent line interference and the non-adjacent line interference occupancy areas is less than a threshold.
[0082] In this embodiment, "including multiple occupied sub-regions" refers to a situation where a determined adjacent interference region is divided into two regions, and the previous distance exceeds a threshold.
[0083] Furthermore, when the type of occupied area is that the distance between the multiple adjacent line interference occupied areas is less than the threshold, it means that when the train is running normally, there may be a number of idle measurement areas within the train range. This threshold refers to the maximum value of the possible number of consecutive idle measurement areas. Since the measurement area occupied by the wheelset must be occupied, the maximum distance between wheelsets / measurement area length can be considered.
[0084] Based on the above-described method for handling interference between adjacent tracks, this embodiment of the invention also provides a corresponding device 400 for handling interference between adjacent tracks. Please refer to [link / reference needed].

[0085] The acquisition module 410 is used to acquire vibration data of a track vehicle based on a grating array, and filter the vibration data according to the energy calculation results of the vibration data to obtain target vibration data.
[0086] The adjacent line interference determination module 420 is used to determine the train occupancy area based on the location information obtained from the target vibration data, and to determine the adjacent line interference situation in the target vibration data by comparing the target vibration data with preset train occupancy area data based on the train occupancy area.
[0087] The tracking management module 430 is used to track and manage the track vehicle based on the interference situation of the adjacent line.
