Description

Technical Field

[0001] The present application relates to the field of railway technology, and in particular to methods, devices, equipment and storage media for arranging contact network pillars at stations. Background Art

[0002] Contact network support (hanging) columns are an important component of the railway electrification system and are the supporting equipment of the contact network. In the railway electrification system, the design and layout of the contact network columns need to take into account factors such as the train's operating speed, the curve radius of the line, and the position of the switch to ensure that the contact network can effectively supply power to the train while being economical. Contact network columns can be divided into three types according to their form: independent arm columns, hard spans, and soft spans. Independent arm columns are generally used for hanging and positioning contact networks between sections or station lines; hard spans and hanging columns are generally used to cross multiple tracks where the spacing between lines does not meet the requirements; soft spans are generally used to cross multiple tracks in EMU depots or storage yards.

[0003] At present, the location design of contact wire pillars at stations is mainly done manually, with contact wire pillars located approximately every 50 meters. For large stations, there are hundreds of contact wire pillars. The location design of contact wire pillars needs to be constantly adjusted, which takes a lot of time, is inefficient, and is prone to errors, omissions, and collisions, which reduces the design quality.

[0055] The purpose, features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0056] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0057] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0058] The main solution of the embodiment of the present application is: determining multiple target turnouts within the target layout range of the track to be designed; creating multiple turnout positioning posts according to the turnout type and turnout pillar design principles of each target turnout; arranging pillars according to the relative starting point pillars, configuration span principle, pillar endpoint range principle, multi-pillar alignment principle and pillar decision conditions of the track to be designed, and determining the layout positions of multiple contact network pillars and the layout scheme of each contact network pillar; determining the contact network pillar layout scheme of the track to be designed based on each turnout positioning post, the layout position of each contact network pillar and the layout scheme of each contact network pillar.

[0059] Currently, the design of catenary pillar positions is primarily done manually, with pillars located approximately every 50 meters. Large stations can have hundreds of these pillars, requiring constant adjustments and time-consuming, resulting in low design efficiency. Given the large number of turnouts and complex variations in track spacing in throat areas, the need to simultaneously consider multiple design requirements, such as span length and pillar limits, can easily lead to errors, omissions, and collisions, compromising design quality.

[0060] This application sets the distance between the contact network pillar and the theoretical switch center for different turnout types. By automatically identifying the turnout type and setting whether the pillar is on the straight or side track side, the contact network pillar at the turnout is automatically created. For special turnout types, the distance between the positioning posts before and after the turnout can also be modified, and the corresponding turnout can be selected to complete the pillar creation at the turnout. Based on the number of tracks suspended by the contact network pillar and the spacing from adjacent tracks, the applicable pillar type is automatically determined to meet the functional and economic requirements of the contact network design process. To meet aesthetic requirements, the contact network pillars are generally designed to be aligned. The arrangement of contact network pillars at stations with different tracks is affected by factors such as the joint position, switch position, curve radius, and span of various suspended tracks. When calculating the pillar position, a common solution that satisfies all kinds of situations is needed to meet the alignment requirements. It is applicable to the layout of multiple tracks at stations. The station is divided into the main line area, throat area, and platform area. The arrangement of joint columns and switch columns is completed first. Then, the intermediate columns of each track are calculated according to the design principles. The alignment with the main line pillars is taken into account during the calculation process. In addition, the line spacing of the pillars relative to the tracks is calculated so that the pillar type meets the design requirements.

[0061] This application creates multiple turnout positioning posts according to the turnout types of multiple target turnouts within the target layout range and combines the turnout pillar design principles, and arranges the pillars based on the relative starting point pillar, the configuration span principle, the pillar endpoint range principle and the pillar decision conditions, determines the layout positions of multiple contact network pillars and the layout plan of each contact network pillar, thereby obtaining the contact network pillar layout plan of the track to be designed, realizing the automatic arrangement of the contact network pillars, saving a lot of human resources, and improving the design efficiency. At the same time, multiple layout requirements are taken into consideration in the design process, thereby improving the design quality and avoiding the occurrence of differences, errors, omissions and the like.

[0062] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device capable of performing the above functions, such as station overhead contact network pillar layout equipment. This embodiment and the following embodiments will be described below using station overhead contact network pillar layout equipment as an example.

[0063] Based on this, the embodiment of the present application provides a method for arranging contact network pillars at a station, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the station contact network pillar arrangement method of the present application.

[0064] In this embodiment, the method includes steps S10 to S40:

[0065] Step S10, determining a plurality of target turnouts within the target layout range of the track to be designed;

[0066] It should be noted that the contact network pillars can be divided into three types according to their form: independent arm pillars, hard spans, and soft spans. Independent arm pillars are generally used for the suspension and positioning of contact networks between sections or station lines; hard spans and hanging pillars are generally used to cross multiple track lines where the spacing does not meet the requirements; soft spans are generally used to cross multiple track EMU depots or storage yards. The schematic diagram of the contact network pillar positions of a typical 4-track station is as follows Figure 2 As shown, #1 and #2 are independent cantilever columns used for turnout positioning, #3 is a hard crossover, and #4 is an independent cantilever column located between the lines.

[0067] It can be understood that the track to be designed refers to the track where the station contact network pillars need to be arranged. The target layout range is determined based on the starting point and end point of the track to be designed, and multiple target switches within the target layout range are obtained.

[0068] Step S20, creating a plurality of turnout locating columns according to the turnout type and turnout column design principle of each target turnout;

[0069] It should be noted that the number and position of the contact suspension positioning pillars above the turnout are different for different turnout types. Common turnout types include 1 / 9, 1 / 12, 1 / 18, and 1 / 42. In this embodiment, the turnout pillar design principle refers to the distance between the turnout positioning pillars and the theoretical turnout center corresponding to different turnout types. For ease of understanding, the turnout pillar design principle is illustrated in Table 1. Figure 3 As shown, Figure 3 This is a schematic diagram of the position of the common 1 / 18 turnout locating column on the straight strand side.

[0070] Table 1

[0071]

[0072] It can be understood that when creating a standard turnout locating column, based on the turnout type of each target turnout and combined with the turnout pillar design principles, the distance between the standard locating column in front of each target turnout and the theoretical turnout center, as well as the distance between the standard locating column behind the turnout and the theoretical turnout center can be determined, and it is clear whether the pillar position is located on the straight strand side or the side strand side of the target turnout, thereby creating the turnout locating column corresponding to each target turnout.

[0073] In a feasible implementation, step S20 may further include steps A11 to A13:

[0074] Step A11, determining the standard switch center positioning distance of each target turnout according to the turnout type and turnout support design principle of each target turnout;

[0075] It should be noted that when creating a standard turnout locating post, the turnout pillar design principles are queried for the theoretical turnout center distance between the standard locating post in front of the turnout and the corresponding turnout type of the target turnout. In this embodiment, the theoretical turnout center distance between the standard locating post in front of the turnout and the theoretical turnout center distance between the standard locating post in back of the turnout constitute the standard turnout center positioning distance for each target turnout.

[0076] Step A12, determining a standard positioning column for each target turnout according to the standard switch center positioning distance of each target turnout and the designed track orientation of each target turnout;

[0077] It should be noted that, based on the design requirements for the locating posts of each target turnout, it is determined whether the posts of each target turnout are located on the straight strand side or the side strand side of the target turnout, thereby determining the position of the locating posts of each target turnout. The position of the locating posts of each target turnout is the design track orientation of each target turnout.

[0078] It can be understood that, based on the turnout design orientation and standard switch core positioning of each target turnout, the standard positioning column of each target turnout can be determined.

[0079] Step A13: define the attributes of the standard positioning column of each target turnout to obtain the turnout positioning column of each target turnout.

[0080] It should be noted that the mileage attribute is assigned to the standard positioning post of each target turnout. The standard positioning post of each target turnout assigned with the mileage attribute is the turnout positioning post of each target turnout.

[0081] It should be noted that if a non-standard turnout locating column needs to be created, the distance values ​​between the front and rear turnout locating columns and the theoretical turnout center should be determined according to the design requirements, and then the turnout locating columns of each target turnout should be determined in combination with the track design orientation of the target turnout.

[0082] It is understood that the automatic arrangement operation of the turnout positioning column pillar is as follows Figure 4 As shown in the figure, based on the design principle of turnout pillars, standard turnout locating pillars are created. You can also modify the distance between the front and rear turnout locating pillars and the theoretical turnout center according to design requirements to create non-standard turnout locating pillars. Select the pillar position on the straight strand side or the side strand side. Select the turnout to be designed. Create pillars and assign mileage attributes. The operation dialog box for turnout layout is as follows Figure 5 shown.

[0083] In this implementation, the standard turnout center positioning distance for each target turnout is determined based on the turnout type and turnout support design principles. The standard locating posts for each target turnout are determined based on the standard turnout center positioning distance and the track design orientation of each target turnout. The attributes of the standard locating posts for each target turnout are defined to obtain the turnout locating posts for each target turnout. This approach enables the automatic creation of turnout locating post supports, improving creation efficiency and accuracy.

[0084] Step S30, laying out the pillars according to the relative starting point pillars of the track to be designed, the principle of configuring spans, the principle of pillar endpoint ranges, the principle of multi-pillar alignment, and the pillar decision conditions, and determining the layout positions of the plurality of catenary pillars and the layout plan of each catenary pillar;

[0085] It should be noted that for large stations, the location of the contact network pillars may conflict with other structures. There are many control factors that need to be considered in the arrangement of the pillars, mainly including: ① Switch section: The contact network pillars in the switch section need to give priority to the positioning function. Generally, standard positioning is adopted. In special cases, the distance from the theoretical switch center can be adjusted, but it cannot exceed the limit. ② Line spacing effect: The contact network pillars generally prefer to use independent arm pillars. For places where the spacing between multiple tracks is insufficient, hard cross-hanging columns are required to support the contact suspension (such as Figure 2 To ensure economic efficiency, for multi-track parallel sections, the inter-track pole solution is preferred when the line spacing requirements are met (e.g. Figure 2 (#4). ③ Impact of other structures: Stations often contain frame bridges, culverts, and bridges. The impact of these structures on the layout of contact network pillars in stations is similar to that of sections. ④ Aesthetic requirements: In sections with multiple parallel tracks, contact network pillars on each track are generally required to be aligned to meet aesthetic requirements.

[0086] It can be understood that, in this embodiment, the principle of configuring the span refers to the spacing requirement between the contact network pillars, and the principle of configuring the span includes: ① Maximum span: the maximum distance between two adjacent suspension points of the same track contact suspension. For the intermediate pillar, it generally refers to the maximum distance between two adjacent pillars of the same track. According to the design specifications, it generally does not exceed 60m. ② Minimum span: the minimum distance between two adjacent suspension points of the same track contact suspension. For the intermediate pillar, it generally refers to the minimum distance between two adjacent pillars of the same track. According to design experience, it can be 30m. ③ Standard span: the recommended distance between two adjacent pillars of the same track, which is determined by factors such as the curve radius and the purpose of the pillar. For straight sections, it is generally 50m. ④ Adjacent span difference: the difference between two adjacent spans. Generally, the adjacent span difference is not more than 10m. ⑤ For the determination of the position of the current design pillar i+1, L min ≤L i+1 ≤L max , and |L i+1 -L i |≤L ad requirements, that is, the distance to the adjacent pillars meets the span requirements, and the span difference meets the requirements.

[0087] It should be understood that the pillar endpoint range principle includes the requirements for the layout of suspension points within the preset pillar range at the starting point of the working condition, and the requirements for the layout of suspension points within the preset pillar range at the end point of the working condition. In this embodiment, the requirements for the layout of suspension points within the preset pillar range at the starting point of the working condition are: the range value consisting of the minimum distance and the maximum distance allowed for the layout of pillars at the starting point of the current working condition, which is used to determine the layout of the first pillar of this working condition. Within this range, there is only one suspension point for the contact network of the current track and the current anchor section. The requirements for the layout of suspension points within the preset pillar range at the end point of the working condition are: the range value consisting of the minimum distance and the maximum distance allowed for the layout of pillars at the end point of the current working condition, which is used to verify the layout of the last pillar of this working condition. Within this range, there is only one suspension point for the contact network of the current track and the current anchor section.

[0088] In specific implementation, for large-scale auto shows, the layout of the contact network pillars must also meet aesthetic requirements. In this embodiment, the multi-pillar alignment principle refers to the alignment of the contact network pillars of each track in the multi-track parallel section under normal circumstances. If there is no solution for aligning all tracks, a pillar is created separately for the track that does not meet the requirements, and the pillar of this track is not aligned with other tracks.

[0089] It should be noted that the pillar decision conditions refer to the principles for determining the pillar form in each track section, which includes but is not limited to the throat section, platform section, and mainline section. In this embodiment, the pillar decision conditions define that the contact network pillar form in the throat section is related to the line spacing and the number of tracks suspended by the pillars. The pillar decision conditions in the throat section are divided into the following situations: ① Only one track is suspended, and the contact network pillars of the section main line, the mainline track outside the throat area, and some independent station line tracks all belong to this situation, such as Figure 6 As shown in the figure, the contact network pillar is set outside the track. ② Two tracks are suspended, but the track spacing D≤D min , a single-column double-cantilever suspension solution can be used, such as Figure 6 As shown in the middle support #2, the contact network support is set outside the outermost track. ③ Two tracks are suspended, but the track spacing D min ≤D≤D mid , a hard crossover scheme across multiple tracks is required, and the hard crossover support is set to meet the line spacing greater than D mid At the required position, tracks with insufficient line spacing are suspended with hard beam davits, such as Figure 6 As shown in the middle pillar #3. ④ Two tracks are suspended, with a track spacing of D mid ≤D≤D max , and the two suspended tracks belong to the station track and the main track or the station track and the station track respectively, in this case the line-to-line pole scheme can be adopted, such as Figure 6 As shown in the middle pillar #4. ⑤ Hang two tracks, the track spacing is greater than D max ≤D, the distance between the two tracks is already far, and due to the arm length limit, it is advisable to use two independent arm columns for separate suspension. min Generally, the track spacing at the farthest turnout location is taken. For No. 1 / 18 turnout, it can generally be 1.5m. mid It is related to the track type, support width and clearance requirements. Let the support width be W and the minimum clearance requirement between the support and the main line be CX. zmin , and the minimum limit requirement of the station line is CX cmin , then when the poles are erected between the main line and the station line, D mid =W+CX zmin +CX cmin , the required distance between the poles between the station lines is D mid =W+2CX cmin . D max The maximum distance between the lines of the vertical poles cannot be between the lines, which is generally twice the maximum length of the arm.

[0090] It can be understood that the relative starting point pillar of the track to be designed is obtained, and the preset position P of the next pillar is calculated according to the configuration span principle and the current working condition. iAnd bring this pillar position to other tracks to check whether the other track pillars are also set at this position to meet the configuration span principle and multi-pillar alignment principle. If it does not meet the requirements, adjust P according to the conflict value i Position, repeat the above steps again to check P i The adaptation of all selected tracks is checked until the requirements are met. If there is no solution to align all tracks, a separate pillar is created for the track that does not meet the requirements. This is a special case, and the pillars of this track are not aligned with other tracks. Verify the track type and line spacing requirements of the pillar positioning points of different tracks, and create independent arm pillars, hard cross-pillars, or line poles according to the pillar decision conditions. Calculate the next pillar in sequence until the design end. Through the above steps, the layout positions and layout plans of multiple contact network pillars corresponding to the track to be designed are obtained. The layout plan of each contact network pillar includes the pillar form of each contact network pillar and the specific suspension plan.

[0091] Step S40: determining the layout plan of the contact network pillars of the track to be designed according to the layout positions of the switch positioning posts and the contact network pillars and the layout plan of the contact network pillars.

[0092] It should be noted that the turnout positioning columns of each target turnout, the layout positions of each contact network pillar and the layout plans of each contact network pillar are summarized, and the mileage attributes are assigned to each contact network pillar to determine the contact network pillar layout plan of the track to be designed.

[0093] The present embodiment provides a method for arranging contact network pillars at a station. The method of the present embodiment determines multiple target turnouts within the target layout range of the track to be designed; creates multiple turnout locating pillars according to the turnout type and turnout pillar design principles of each target turnout; arranges pillars according to the relative starting point pillars, configuration span principle, pillar endpoint range principle, multi-pillar alignment principle and pillar decision conditions of the track to be designed, and determines the layout positions of multiple contact network pillars and the layout scheme of each contact network pillar; determines the contact network pillar layout scheme of the track to be designed based on the layout positions of each turnout locating pillar, each contact network pillar and the layout scheme of each contact network pillar. Through the above method, according to the turnout types of multiple target turnouts within the target layout range and combined with the turnout pillar design principles, multiple turnout positioning pillars are created, and the pillars are laid out based on the relative starting point pillars, the configuration span principle, the pillar endpoint range principle and the pillar decision conditions, and the layout positions of multiple contact network pillars and the layout plan of each contact network pillar are determined, so as to obtain the contact network pillar layout plan of the track to be designed, realize the automatic arrangement of the contact network pillars of the station, save a lot of human resources, and improve the design efficiency. At the same time, multiple layout requirements are taken into consideration in the design process, the design quality is improved, and the occurrence of differences, errors, omissions and the like is avoided.

[0094] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above embodiment 1 can be referred to the above introduction and will not be described in detail later. Figure 7 , step S30, the station contact network pillar arrangement method further includes steps S31 to S34:

[0095] Step S31, determining the position of the preset pillars according to the relative starting pillars of the track to be designed and the configuration span principle;

[0096] It should be noted that the track to be designed may include one or more tracks. Select the relative starting point pillar of a track to be designed and obtain the track number N where the pillar is located. i , calculate the next pillar preset position P according to the configuration span principle and current working conditions i , the next pillar relative to the starting pillar is the preset pillar, and the preset position of the next pillar is P i This is the pillar position of the preset pillar.

[0097] Step S32, determining the position of the pillars according to the predetermined pillar positions, the pillar endpoint range principle, the multi-pillar alignment principle, the configuration span principle, and the pillar layout positions of adjacent tracks;

[0098] It should be noted that the pillar layout positions of adjacent tracks refer to the corresponding pillar layout positions of other tracks adjacent to a selected track. The preset pillars are brought into other adjacent tracks to verify whether the pillars of other tracks are also set at this position to meet the configuration span principle, multi-pillar alignment principle and pillar endpoint range principle.

[0099] Step S33, when the pillar positions meet the pillar position layout requirements, determining the layout plan of the preset pillars according to the pillar decision conditions and the pillar positions;

[0100] It should be noted that when the preset pillars are brought into other adjacent tracks and it is verified that the pillars of other tracks are also set at this position and meet the configuration span principle and the pillar endpoint range principle, it means that the pillar position of the preset pillar meets the pillar position layout requirements. At this time, the track type and line spacing requirements of different track spider points are verified, and the pillar type and corresponding suspension scheme of the preset pillar are determined according to the pillar decision conditions, thereby obtaining the layout plan of the preset pillar.

[0101] It is understandable that if other track pillars are also set at this position and do not meet the configuration span principle and pillar end point range principle, P is adjusted according to the conflict value. i Position, repeat the steps again: bring the preset pillar into other adjacent tracks, verify whether the other track pillars are also set at this position to meet the configuration span principle and pillar end point range principle, verify Pi The alignment of all selected tracks is repeated until the requirements are met. If there is no solution that satisfies all track alignment requirements, a separate pillar is created for the track that does not meet the requirements. This is a special case where the pillar of this track is not aligned with other tracks.

[0102] In a feasible implementation, step S33 may further include steps B11 to B15:

[0103] Step B11, determining the current track interval according to the pillar position;

[0104] Step B12, when the current track section is a throat section, determining the number of strut suspension tracks of the preset strut;

[0105] Step B13, when the number of tracks suspended by the support is the first number of tracks, obtaining the current track spacing;

[0106] It should be noted that when the current track interval of the pillar position of the preset pillar is the throat interval, the number of pillar hanging tracks of the preset pillar is obtained. When the number of pillar hanging tracks is two, it means that the current number of pillar hanging tracks is the first track number. At this time, the current track spacing D is obtained.

[0107] Step B14: When the current track spacing is less than or equal to a first spacing threshold, determining that the layout orientation of the preset support is an outer track orientation, and determining that the suspension scheme of the preset support is a single-column double-cantilever suspension scheme;

[0108] It should be noted that the first distance threshold refers to the minimum distance D min , D min Generally, the track spacing at the farthest turnout location is taken. The number of tracks suspended on the support is the first track number and D≤D min , a single-column double-cantilever suspension solution can be used, such as Figure 6 As shown in the middle pillar #2, the preset pillar is set at the outermost track outside. In this embodiment, the outermost track outside is the track outside position.

[0109] Step B15: determining the layout of the preset pillars according to the outer orientation of the track and the single-column double-cantilever suspension scheme.

[0110] It should be noted that the layout plan of the preset pillars can be obtained through the outer side orientation of the track and the single-column double-arm suspension plan.

[0111] In this embodiment, the current track interval is determined according to the position of the pillar; when the current track interval is the throat interval, the number of tracks suspended by the pillar of the preset pillar is determined; when the number of tracks suspended by the pillar is the first number of tracks, the current track spacing is obtained; when the current track spacing is less than or equal to the first spacing threshold, the layout orientation of the preset pillar is determined to be the track outer orientation, and the suspension scheme of the preset pillar is determined to be a single-pillar double-arm suspension scheme; the layout scheme of the preset pillar is determined according to the track outer orientation and the single-pillar double-arm suspension scheme. Through the above method, it is ensured that when two tracks are suspended, but the track spacing D≤D min In this case, an accurate preset pillar layout plan can be obtained.

[0112] The above is only one feasible implementation of step S33 provided in this embodiment, and this embodiment does not specifically limit the specific implementation of step S33.

[0113] In a feasible implementation manner, after step B13, steps C11 to C13 may also be included:

[0114] Step C11: when the current track spacing is greater than or equal to the first spacing threshold and less than or equal to the second spacing threshold, obtaining the line spacing of the current track;

[0115] It should be noted that the second spacing threshold refers to the critical value D related to track type, support width, and clearance requirements. mid In this embodiment, the width of the pillar is W, and the minimum limit requirement between the pillar and the main line is CX. zmin , and the minimum limit requirement of the station line is CX cmin , then when the poles are erected between the main line and the station line, D mid =W+CX zmin +CX cmin , the required distance between the poles between the station lines is D mid =W+2CX cmin . D max The maximum distance between the lines of the vertical poles cannot be between the lines, which is generally twice the maximum length of the arm.

[0116] Step C12: when the line spacing of the current track does not meet the preset line spacing condition, determining that the preset support suspension scheme is a hard beam davit suspension scheme;

[0117] It should be noted that when the number of strands suspended from the pillar is the first strand and D min ≤D≤D mid When the hard crossover scheme across multiple tracks is adopted, the line spacing of the current track is obtained. The hard crossover support is set to meet the line spacing greater than D midAt the required position, tracks with insufficient line spacing are suspended with hard beam davits, such as Figure 6 In this embodiment, the preset line spacing condition refers to the line spacing of the current track>D mid Therefore, when the line spacing of the current track does not meet the preset line spacing condition, the suspension scheme of the preset pillar is determined to be the hard beam davit suspension scheme.

[0118] Step C13: Determine the layout plan of the preset pillars according to the rigid beam suspender suspension plan.

[0119] In this embodiment, when the current track spacing is greater than or equal to the first spacing threshold and less than or equal to the second spacing threshold, the line spacing of the current track is obtained; when the line spacing of the current track does not meet the preset line spacing condition, the suspension scheme of the preset pillar is determined to be a hard beam sling suspension scheme; and the layout scheme of the preset pillar is determined according to the hard beam sling suspension scheme. Through the above method, it is ensured that when two tracks are suspended, but the track spacing D min ≤D≤D mid In this case, an accurate preset pillar layout plan can be obtained.

[0120] In a feasible implementation manner, after step B13, steps D11 to D12 may also be included:

[0121] Step D11, when the current track spacing is greater than or equal to the second spacing threshold and less than or equal to the third spacing threshold, determining the current track type;

[0122] Step D12: When the current track type is a preset track type, determine that the layout scheme of the preset pillars is an inter-line pole layout scheme.

[0123] It should be noted that the third spacing threshold refers to the maximum line spacing D between the poles. max , generally take 2 times the maximum length of the cantilever. When the number of strands suspended from the pillar is the first strand and D mid ≤D≤D max When the two suspended tracks belong to the station track and the main track or the station track and the station track, the layout scheme of the preset pillars can be determined as the line-to-line pole scheme, such as Figure 6 As shown in pillar #4.

[0124] In this embodiment, when the current track spacing is greater than or equal to the second spacing threshold and less than or equal to the third spacing threshold, the current track type is determined; when the current track type is the preset track type, the preset support arrangement scheme is determined to be the line-to-line vertical pole arrangement scheme. By the above method, it is ensured that when two tracks are suspended, but the track spacing D mid ≤D≤D maxIn this case, an accurate preset pillar layout plan can be obtained.

[0125] In a feasible implementation manner, before step C11, steps DE11 to E12 may also be included:

[0126] Step E11, obtaining the critical value of the pillar main line clearance and the critical value of the pillar station line clearance;

[0127] Step E12, performing threshold calculation based on the pillar main line clearance critical value, the pillar station line clearance critical value and the preset pillar width to determine a second spacing threshold.

[0128] It should be noted that the critical value of the pillar positive line limit refers to the minimum limit CX between the pillar and the positive line. zmin The critical value of the support and station line limit refers to the minimum limit CX between the support and the station line. cmin , the preset support width refers to the support width D, then D is the width of the support between the main line and the station line. mid =W+CX zmin +CX cmin , the required distance between the poles between the station lines is D mid =W+2CX cmin , thereby obtaining the second spacing threshold in different situations.

[0129] In this implementation, a critical value for the pillar mainline clearance and the pillar stand-line clearance is obtained; a threshold calculation is performed based on these critical values, along with the preset pillar width, to determine the second spacing threshold. This approach allows accurate pillar clearances to be obtained, laying the foundation for accurate subsequent contact network pillar placement.

[0130] It is understandable that when the current track section is a throat section, but the number of tracks suspended by the preset pillars is one track, the main line of the section, the main line tracks outside the throat area, and some independent station line tracks contact network pillars all belong to this situation, such as Figure 6 As shown in the figure, the contact network pillar is set outside the track.

[0131] In the specific implementation, the current track interval is the throat interval, but the number of tracks suspended by the preset support is two tracks, and the track spacing is greater than D max ≤D, at this time the distance between the two tracks is already far, and due to the limitation of the arm length, it is advisable to use two independent arm columns for separate suspension.

[0132] Step S34 , determining the layout positions of a plurality of contact network pillars and the layout plan of each contact network pillar according to the layout plan of the preset pillars and the pillar positions of the preset pillars.

[0133] It should be noted that based on the position of the preset pillar, combined with the configuration span principle and the current working conditions, the calculation of the next pillar preset position is started. The next pillar preset position is then brought into other tracks to verify whether the other track pillars set at this position meet the configuration span requirements. If the requirements are not met, the position is adjusted according to the conflict value, and the above steps are repeated again to verify the compatibility with all selected tracks until the requirements are met. If there is no solution to align all tracks, a pillar is created separately for the track that does not meet the requirements. This is a special case, and the pillar of this track is not aligned with other tracks. The track type and line spacing requirements of the pillar positioning points of different tracks are verified, and independent arm pillars, hard cross-beam pillars, or line-to-line poles are created according to the pillar decision conditions. The next pillar is calculated in sequence until the design end point, and finally the layout position of all contact network pillars for the track to be designed and the layout plan of each contact network pillar are obtained.

[0134] This embodiment provides a method for arranging contact network pillars at a station. This embodiment determines the position of a preset pillar based on the relative starting point pillar of the track to be designed and the configuration span principle; determines the position of the preset pillar based on the pillar position, the pillar endpoint range principle, the multi-pillar alignment principle, the configuration span principle, and the pillar layout position of adjacent tracks; determines the layout plan of the preset pillar based on the pillar decision conditions and the pillar position when the pillar position meets the pillar position layout requirements; and determines the layout positions of multiple contact network pillars and the layout plan of each contact network pillar based on the layout plan and the pillar position of the preset pillar. In this way, various constraints and factors are taken into account when arranging the pillars, ensuring design quality.

[0135] For example, in order to help understand the implementation process of the station contact network pillar arrangement method obtained by combining this embodiment with the above embodiment 1, please refer to Figure 8 , Figure 8 A brief flow chart of a station overhead contact network pillar arrangement method is provided, specifically:

[0136] In this example, pillar layout design principles are configured. Key design principles include span design principles (also known as span configuration principles), multi-pillar alignment principles for multi-track parallel sections, turnout pillar design principles, and bridge and roadbed pillar layout principles. Select the track to be designed and select the starting and ending points for automatic layout. The automatic pillar layout algorithm is executed. The positions of each pillar are calculated, the pillars are created, and their mileage attributes are assigned.

[0137] In this embodiment, the process of aligning and arranging catenary pillars for multiple tracks in parallel is as follows: ① Obtain the list of selected tracks and obtain the catenary pillars arranged in each track. ② Obtain the pillar with the relative starting point and obtain the track number N where the pillar is located. i③ According to the configuration span rule: L min ≤L i+1 ≤L max , and |L i+1 -L i |≤L ad and the current working condition, calculate the next pillar preset position P i ④ Bring this pillar position to other tracks and check whether the other track pillars are also set at this position to meet the span requirements. ⑤ If it does not meet the requirements, adjust P according to the conflict value i Position, repeat step ④ again, check P i ⑥ Check the adaptability of all selected tracks until the requirements are met. If there is no solution to align all tracks, create a separate pillar for the track that does not meet the requirements. This is a special case where the pillar of this track is not aligned with other tracks. ⑥ Verify the track type and line spacing requirements of the different track pillar positioning points, and create independent arm pillars, hard cross pillars, or line poles according to the pillar decision conditions. ⑦ Calculate the next pillar in sequence until the design end point
