[0059] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the application, and are not used to limit the application.

[0060] In order to better understand the technical solutions of the application, the following will be described in detail in combination with the drawings of the specification and the specific embodiments.

[0061] Because the prior art does not combine the reminder information with the information that the driver should pay attention to, and does not quantify the risk that the road information affects the driving of the vehicle.

[0062] The application provides a solution, which configures standard span, maximum span, minimum span, maximum allowable value of adjacent span difference as design parameters in the initial version of catenary plane layout; automatically obtains bridge and bridge pier attributes based on the bridge table and the bridge pier table; performs support offset arrangement calculation based on the design parameters and the bridge and bridge pier attributes to obtain selected support positions; and realizes automatic arrangement of catenary supports based on the selected support positions, so as to meet the requirements of bridge type description, catenary support position and bridge pier distance setting, and catenary support automatic arrangement of bridge section.

[0063] It should be noted that the execution subject of the embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a bridge section catenary support post position automatic arrangement device, etc. The following will take a road information prompting device as an example to describe the embodiment and each of the following embodiments.

[0064] Based on this, the embodiment of the present application provides a bridge section catenary support post position automatic arrangement method, which refers to Figure 1 , Figure 1 The flowchart of the first embodiment of the bridge section catenary support post position automatic arrangement method of the present application is shown in FIG. 1.

[0065] In the embodiment, the bridge section catenary support post position automatic arrangement method comprises steps S10-S40:

[0066] Step S10, configuring a standard span, a maximum span, a minimum span, and a maximum allowable value of a difference between adjacent spans as design parameters in a preliminary catenary plane layout diagram;

[0067] It should be noted that the standard span refers to a typical span length expected or planned in bridge design;

[0068] The maximum span refers to the longest distance that the bridge can safely span under the design specification or technical requirement;

[0069] The minimum span refers to the shortest span length allowed in the design;

[0070] The maximum allowable value of the difference between adjacent spans refers to the maximum length difference allowed between adjacent spans in a bridge.

[0071] It can be understood that the strategy is to design a catenary plane layout diagram, so the preliminary catenary plane layout diagram is composed of some basic structures and parameters.

[0072] It should be understood that the minimum span, the maximum span, the standard span, the offset distance between the support post position and the beam joint, and the maximum value of the difference between adjacent spans are all fixed values according to the speed grade of the railway project and the line conditions, which can be software calculation values or parameterized fixed values.

[0073] Before step S10, a support post arrangement command can also be selected, a configuration dialog box is popped up, and then subsequent configurations are performed in the configuration dialog box.

[0074] Further, before step S10, it also includes obtaining an arrangement track, an automatic arrangement area, and a reference support post; and designing a preliminary catenary plane layout diagram based on the arrangement track, the automatic arrangement area, and the reference support post.

[0075] It should be noted that the reference pillar is the previous pillar of the current arrangement area in the overhead contact line plan design, generally the nearest overhead contact line pillar adjacent to the outside of the automatic arrangement area of the pillar, and the entity must contain the mileage information of the position thereof;

[0076] The automatic arrangement area is used to describe the bridge range in the overhead contact line plan design, and contains the section baseline, bridge side line, bridge pier station number, pier station mileage, and bridge type information.

[0077] The arrangement track refers to determining the path and track arrangement scheme of the railway or track to ensure proper docking and coordination of the railway system and the bridge structure.

[0078] In step S20, the bridge and bridge pier attributes are automatically obtained based on the bridge table and the bridge pier table;

[0079] It should be noted that, as shown in Figure 2 and Figure 3 , the strategy proposes a bridge and pier attribute description method for overhead contact line pillar arrangement, i.e., a bridge table and a bridge pier table. It can be seen that the horizontal coordinates of the bridge table are field name, type, unit, optional, value range, engineering significance, the vertical coordinates are serial number, bridge name, center mileage crown number, center mileage, span style, start point mileage crown number, start point mileage, end point mileage crown number, end point mileage, full bridge length, standard bridge deck width, line number, note, whether it is an existing bridge, and long chain before and after. The horizontal coordinates of the bridge pier table are field name, type, unit, optional, value range, engineering significance, and the vertical coordinates are serial number, bridge number, pier number, mileage crown number, mileage, beam type, pier top elevation, lateral offset, and note.

[0080] The introduction of the bridge table and the bridge pier table attributes can describe the bridge start point mileage, end point mileage, and beam surface attributes, and realize automatic identification of the bridge and its type.

[0081] As shown in Figure 4 , the operation flowchart provided by the first embodiment of the bridge section overhead contact line pillar position automatic arrangement method of the present application is shown in Figure 4 . Select the pillar arrangement command, and pop up the configuration dialog box. Configure the design requirements such as standard span, maximum span, minimum span, maximum allowed value of adjacent span difference, pillar and beam joint offset distance, etc. Select the arrangement track and the automatic arrangement area. Select the reference pillar. Automatically obtain the bridge and pier attributes, and execute the automatic calculation pillar offset arrangement calculation step. Create the pillar and assign the attribute mileage value, complete the pillar automatic arrangement. Until the mileage value of the last selected pillar calculated automatically exceeds the mileage range of the automatic arrangement area, complete the automatic arrangement of all pillars in the area.

[0082] Step S30, based on the design parameters and the bridge and bridge pier properties, the support offset arrangement calculation is performed to obtain the selected support position;

[0083] In a specific implementation, the step of support offset arrangement calculation is to automatically identify the bridge pier type as a box girder, a continuous girder, or a T girder. According to the bridge type, the offset distance Off between the support position and the beam joint is given. On the size and mileage side of the bridge pier, the support is preset at the offset distance Off. It is verified whether the preset positions on both sides of the bridge pier meet the maximum span, the minimum span, and the maximum adjacent span difference requirements. In the case where the span meets the critical value requirement, the deviation between the current span and the standard span at the preset support position is calculated. The preset support position with the minimum standard span deviation is selected as the selected support position.

[0084] It can be understood that the selected support is used to describe the preset support that meets the design rules such as the standard span, the maximum span, the minimum span, the maximum adjacent span difference, and the distance between the support position and the bridge joint in different bridge types in the overhead contact line plan layout design. The selected support has a corresponding support object entity in the design drawing.

[0085] Step S40, based on the selected support position, the automatic arrangement of the overhead contact line support is realized.

[0086] Further, an initial overhead contact line plan layout is obtained. In the initial overhead contact line plan layout, the corresponding support is created based on the selected support position and the attribute mileage value is assigned. The layout tracks in the initial overhead contact line plan layout are selected one by one for arrangement until the last selected support exceeds the automatic arrangement area, and the automatic arrangement of the overhead contact line support is completed. The step of selecting the layout tracks in the initial overhead contact line plan layout one by one for arrangement can also include simultaneously selecting all the layout tracks in the initial overhead contact line plan layout for arrangement.

[0087] It should be noted that according to the drawing habit, the selection and configuration steps in the operation process can be adjusted or alternated. Among them, in the track selection step, selecting multiple tracks at a time and selecting single tracks one by one for automatic support arrangement are regarded as equivalent technical solutions.

[0088] In a specific implementation, the support is created and the attribute mileage value is assigned, and the automatic arrangement of the support is completed. Until the mileage value of the last selected support exceeds the mileage range of the automatic arrangement area, the automatic arrangement of all supports in the area is completed.

[0089] The embodiment provides a catenary support post position automatic arrangement method for a bridge section, wherein a standard span, a maximum span, a minimum span, and a maximum allowed value of a difference between adjacent spans are configured as design parameters in a preliminary catenary plane layout; bridge and bridge pier table attributes are automatically obtained based on a bridge table and a bridge pier table; selected support post positions are obtained through support post offset arrangement calculation based on the design parameters and the bridge and bridge pier table attributes; and automatic arrangement of catenary support posts is realized based on the selected support post positions, so that the bridge type description and the catenary support post position and bridge pier spacing setting requirements and the catenary support post automatic arrangement requirements of the bridge section are met.

[0090] Based on the first embodiment of the application, the same or similar contents as the above-mentioned first embodiment can be referred to the above description, and the subsequent description will not be repeated. On this basis, please refer to Figure 5 , step S30, the catenary support post position automatic arrangement method for a bridge section further comprises steps S301-S305:

[0091] Step S301, the bridge pier type is identified through an enumeration method based on the bridge and bridge pier table attributes.

[0092] In the specific implementation, the bridge type is identified as a box girder, a continuous girder or a T girder according to the enumeration method.

[0093] It should be noted that the enumeration method is a commonly used algorithm strategy in mathematics and computer science, and the basic idea is to systematically list and check all possible cases to find a solution to a problem or achieve a specific goal. The enumeration method is usually used to find a specific solution in a limited search space, and the basic steps include determining the problem space, listing possible cases, checking the solution, and outputting the result.

[0094] Step S302, the offset distance between the support post position and the beam joint is determined based on the bridge pier type.

[0095] In the specific implementation, the offset distance Off between the support post position and the beam joint is set according to the bridge type.

[0096] It should be noted that according to the design requirements of the bridge structure, the support position should be located at the strength center of the beam to ensure the stability and carrying capacity of the bridge. The offset distance of the beam joint also needs to meet the requirements of the structural design to ensure the continuity of the beam and the integrity of the structure; different types of bridges (such as simply supported beam, continuous beam, suspension bridge, etc.) and different arrangements (such as pier spacing, beam span, etc.) will affect the setting of the support position and the offset distance of the beam joint; generally, factors such as pier position, span length, etc. will affect the arrangement of the support position and the beam joint; considering the construction and maintenance of the bridge, the support position and the offset distance of the beam joint need to fully consider the needs of the construction process and maintenance access; reasonable support position and beam joint arrangement can reduce the construction difficulty and cost, and improve the maintenance efficiency of the bridge; when determining the offset distance of the support position and the beam joint, the safety operation of the bridge needs to be considered. This includes considering the influence of vehicle load, wind load, earthquake load, etc. on the bridge structure to ensure the safety of the bridge in the use stage.

[0097] In step S303, a preset support is set on the size and mileage side of the bridge pier based on the offset distance of the support position and the beam joint;

[0098] The support is preset on the size and mileage side of the bridge pier with an offset distance Off.

[0099] It should be noted that the size and mileage side of the bridge pier refers to the lateral position of the size and position of the bridge pier on the mileage line of the bridge.

[0100] It can be understood that the preset support is used to describe the possible support theoretically calculated based on the current reference support and the automatic arrangement range in the overhead contact system plan layout design. The preset support only contains mileage information. The preset support does not form a specific graphic element in the design drawing.

[0101] In one embodiment, after step S303, when the preset support meets the preset critical value requirement;

[0102] The maximum span, the minimum span, and the maximum allowable value of the adjacent span difference in the design parameters are obtained;

[0103] When the current span of the preset support meets the requirements of the maximum span and the minimum span, and the adjacent span difference of the preset support is less than or equal to the maximum allowable value, it is determined that the preset support meets the preset critical value requirement.

[0104] It should be noted that the preset critical value requirement is that the current span L i+1 meets the minimum span L min and the maximum span L max requirement, that is, min ≤L i+1 ≤L max ;

[0105] The difference between adjacent spans is less than the maximum allowable value L ad , i.e. L i -L ad ≤ L i+1 ≤ L i + L ad .

[0106] In another embodiment, after step S303, when the preset support does not meet the preset critical value requirement;

[0107] Adjust the offset distance value of the preset support and the bridge pier.

[0108] According to the adjusted offset distance value, the preset support is repositioned on the size and mileage sides of the bridge pier.

[0109] Step S304, when the preset support meets the preset critical value requirement, the deviation value of the span of the preset support and the standard span is calculated;

[0110] It should be noted that the standard span deviation is a parameter used to describe the position of the support in the design of the overhead contact system plan, which measures the advantages and disadvantages of the preset support position.

[0111] It should be understood that the standard span deviation parameter is defined by the strategy, and the optimal support position under the current standard span value is determined by selecting the minimum value of the parameter. By calculating the difference between the preset support span and the standard span on both sides of the bridge pier in the automatic arrangement range, the critical point of the positive and negative change of the difference value is selected, which is considered as an equivalent technical solution.

[0112] In a specific implementation, under the condition of meeting the span checking condition, the current span L i+1 and the standard span L stand deviation Dif = |L i+1 -L stand |.

[0113] Step S305, based on the deviation value, the preset support position with the minimum deviation value is selected as the selected support position.

[0114] As Figure 6 shown, Figure 6 is the operation flowchart provided by the second embodiment of the automatic arrangement method of the overhead contact system support position of the bridge section. According to the type of the bridge pier, the offset distance of the support at the pier is determined, and the preset support is arranged on both sides of the size and mileage of the bridge pier with the offset distance. It is judged whether the preset support meets the minimum span, maximum span, and maximum adjacent span difference requirement. If not, the offset distance value of the support and the pier is adjusted, and the preset support is repositioned. If yes, the deviation of the span of the preset support and the standard span is calculated, and then the support position with the minimum standard span deviation is selected.

[0115] It can be understood that the pillar offset arrangement process steps defined by the strategy can be split or combined with each other to realize automatic arrangement of the preset pillar positions on both sides of the bridge pier. The checking sequence of the minimum span, the maximum span, the maximum adjacent span difference, and the standard span deviation can be split, combined, or sequentially adjusted.

[0116] The embodiment proposes a bridge section catenary pillar position automatic arrangement method, which can design pillar automatic arrangement rules based on the standard span, the maximum span, the minimum span, the maximum allowed value of the adjacent span difference, and the bridge and pier type attributes, to realize automatic arrangement of the catenary pillars under different bridge types.

[0117] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the bridge section catenary pillar position automatic arrangement method of the present application. More forms of simple transformation based on this technical concept are within the protection scope of the present application.
