Background

The ZPW-2000 section track circuit has the functions of section track section vacancy/occupation check and information transmission to vehicle-mounted signal equipment, and is composed of indoor equipment, trackside equipment and cables for connecting the indoor equipment and the outdoor equipment. The track circuit of a segment can only operate reliably when the length of the track segment is not greater than a certain length, which is defined as the limit length of the track circuit of the segment. The block subarea is an interval section which is formed by two adjacent signal machines or signal sign boards passing through in the same direction, and two ends of each block subarea are provided with steel rail insulation joints. When the length of a certain block subarea in the section exceeds the limit length of the track circuit, one or more than one insulating joint is added in the block subarea and is divided into two or more than two track sections, so that the length of the track circuit of each section is not more than the limit length.

The limit length of the interval track circuit is greatly influenced by the foundation conditions of the line structures such as roadbeds, bridges, tunnels, ballast/ballastless tracks, ballast resistors and the like. The traditional engineering design method is that the limit length of the track circuit of each section is calculated one by contrasting each group of parameters of a reliable working length table of ballastless and ballasted track circuits in the technical conditions of the ZPW-2000 track circuit according to the basic conditions of the track structure of each section of track, and whether the length of each section exceeds the corresponding limit length is checked.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, an embodiment of the present invention provides a method for dividing a track circuit of an interval, where the method includes the following steps:

s101, acquiring an annunciator odometer, a bridge and tunnel ballastless track odometer and railway ballast resistance data, wherein the annunciator odometer is used for storing the mileage information of each signal point, and the bridge and tunnel ballastless track odometer is used for storing the mileage information of each track foundation structure; copying data in the signal machine odometer into a 0-time segmentation signal machine odometer;

and S103, analyzing each block subarea after the preliminary division is finished in sequence, and adjusting the division points of the block subareas with the length exceeding the limit length of the track circuit.

Further, still include: and calculating the track circuit limit length of each track section of the block partition after the division point is added, and continuing to adjust the division point of the block partition with the length exceeding the track circuit limit length, wherein the adjustment of the division point comprises the adjustment of the division point by adopting the proportion coefficient method to optimize the division point and add the division point.

The interval track circuit dividing method provided by the invention has the advantages that the track circuit dividing design process is programmed, manual calculation is not required, no matter how complex the basic conditions of the line structure can be easily processed, the use is simple and convenient, and the design quality and the design efficiency are effectively improved.

The above process is described in detail below by specific examples.

In the step S101, each record in the signal odometer may have a plurality of fields, for example, the fields may include "name", "type", "mileage", and the like, where the "type" may be a type of a signal point, and may include an inbound signal, a reverse inbound signal, an outbound signal, a reverse outbound signal, a passing signal or a division point (an inter-track circuit division point), and the like, and the signal odometer may uniquely identify the passing signal by using the first identification value and uniquely identify the division point by using the second identification value, and the inbound signal, the reverse inbound signal, the outbound signal, and the reverse outbound signal may uniquely identify themselves by using their own names or device numbers. The line between adjacent passing signals and the dividing point or between adjacent dividing points and the dividing point is a track section, and the line between every two passing signals is a block subarea.

The odometer of the signal machine can adopt the form of an Excel meter, and the data format can accord with the general habit of reconnaissance design, so that the data format is simple, and the requirement of software programming can be met. The mileage data of the signal machine can be provided by the driving professional, and the mileage value of each signal point can be preset by engineering designers.

For the simplicity of the description of the present invention, the traffic signal odometer example data may be intercepted only on a segment of the downlink without regard to line chain breakage. For example, the traffic signal odometer can be shown in table 1 below, in which a column with a name is entered as "0" to indicate that a signal point is a passing traffic signal or a division point. The value of the type one column is 17, the signal point is a passing signal machine or a signal sign board, the value of the type one column is 15, the signal point is a dividing point, and the value of the mileage column indicates the mileage value of the position where the signal point is located.

TABLE 1

Annunciator odometer example

Name (R)	Type (B)	Mileage
			0	17	K840+950
0	17	K842+800
			0	17	K844+690
0	17	K846+590
			0	17	K848+490
0	17	K850+290
			0	17	K851+870
0	17	K853+440
			0	17	K855+190
0	17	K856+770
			0	17	K858+170
0	17	K859+820
			0	17	K861+320

And copying the data in the signal odometer into a 0-time division signal odometer, namely, the data in the 0-time division signal odometer is consistent with the data in the signal odometer.

Each record in the bridge and tunnel ballastless track odometer may have a plurality of fields, for example, the fields may include "name", "type", "starting mileage", "ending mileage", and the like, where "type" may be a type of track infrastructure, for example, may include types of bridge, tunnel, ballastless, and the like. In addition, the ballasted track sections are provided in the table except for ballastless sections.

The bridge and tunnel ballastless track odometer can adopt an Excel meter, and the data format can accord with the general habit of reconnaissance design, so that the data format is simple, and the requirement of software programming can be met. The mileage information of the bridge, the tunnel and the ballastless track can be respectively derived from professional mileage data in the fields of the bridge, the tunnel and the track. The mileage range in the bridge and tunnel ballastless track odometer can be consistent with the mileage range of the annunciator odometer. For example, the bridge and tunnel ballastless track odometer can be shown in table 2 below.

TABLE 2

The ballasted track ballast resistor can be a ballast resistor of a ballasted track section in a line, and a man-machine dialog box can be adopted to read a 'semaphore odometer' file and a 'bridge and tunnel ballastless track odometer' file; and reading the ballast resistor selected by the user to be used as the ballast resistor. In order to simplify programming, only a single ballast resistor can be processed in each execution, and if ballast track sections with different ballast resistors exist on a line, an annunciator odometer can be compiled in sections according to the different ballast resistors.

Each track foundation structure can comprise a ballast roadbed, a ballast bridge, a ballast tunnel, a ballastless roadbed, a ballastless bridge and a ballastless tunnel; the parameters of the ballast track can comprise the length of a ballast roadbed, the length of a ballast bridge, the length of a ballast tunnel and the total length of a target ballast tunnel with the largest proportion in the ballast tunnels of the track section; the ballastless track parameters can comprise the length of a ballastless roadbed, the length of a ballastless bridge, the length of a ballastless tunnel and the total length of a target ballastless tunnel with the largest proportion in the ballastless tunnels of the track section.

For each track section, the track section can comprise a ballastless track section and a ballasted track section, and the ballasted subgrade length, the ballasted bridge length and the ballasted tunnel length can be the subgrade length, the bridge length and the tunnel length in the ballasted track section respectively; the length of the ballastless roadbed, the length of the ballastless bridge and the length of the ballastless tunnel can be the roadbed length, the bridge length and the tunnel length in the ballastless track section respectively; a ballast track section of one track section may include a plurality of tunnel portions, and some tunnels may be very long and thus extend to other track sections, a target ballast tunnel is a tunnel with the largest proportion among the plurality of tunnel portions included in the ballast track section, and a target ballastless tunnel is a tunnel with the largest proportion among the plurality of tunnel portions included in the ballastless track section.

In step S102, the limit length of the track circuit of each track section is calculated according to the data in the 0-time split signal machine odometer, and in order to conveniently check which track sections do not reach the standard, a track circuit limit length check meter can be generated based on the signal machine odometer, the bridge and tunnel ballastless track odometer and the calculated limit length of the track circuit of each track section.

For example, based on tables 1 and 2, a track circuit limit length check table without a dividing point is obtained as shown in table 3 below, where the table records lengths of track base structures in each track section (including ballastless bridges, ballastless tunnels, ballastless bases, ballasted bridges, ballasted tunnels and ballasted bases), a maximum occupied tunnel total length (including ballast full tunnels and ballastless full tunnels), a block partition length (referred to as a partition length for short), a track section length (referred to as a section length for short), a track circuit limit length (referred to as a limit length for short), and an excess limit length flag (referred to as an overlength flag for short). When the length of the track section is greater than the limit length of the track circuit, "the mark position exceeding the limit length" is set to "1", otherwise, the mark position exceeding the limit length "is set to" 1 ", so that a user can be reminded to increase the interval division point or adjust the interval division point position. Each block partition in this example data is not partitioned, containing only one track segment. The data of the overlength flag column is 1, which indicates that the length of the track section is greater than the limit length of the track circuit, and the track section needs to be divided. Type 17 indicates that the section passes through a traffic signal or a signal signboard. The resistance value of the railway ballast is 1.0.

TABLE 3

As can be seen from the above table, the track segment length of each block partition in the 0-time division signal odometer is greater than the track circuit limit length, and each block partition needs to be divided into two halves to form a 1-time division signal odometer after division. Based on the 1-time division signal odometer, a track circuit limit length check table after halving division can be obtained as shown in the following table 4, and the data in the 1-time division signal odometer is corresponding to the first three columns in the table 4. Each block partition in this example data has been bisected, containing two track sections. The data of the overlength flag column is 1, which indicates that the length of the track section is greater than the limit length of the track circuit, and the track section needs to be divided. Type 17 indicates that the section passes through a traffic signal or a signal signboard, and type 15 indicates a section division point. The resistance value of the railway ballast is 1.0.

TABLE 4

As can be seen from the above table, some of the block sections in the signal odometer divided by 1 time have sections whose track section lengths are greater than the limit length of the track circuit, and these block sections need to be divided into three equal parts again, so that the signal odometer divided by 2 times is formed. Based on the 2-time division signal odometer, a trisection divided track circuit limit length check table can be obtained as shown in the following table 5, and the data in the 2-time division signal odometer corresponds to the first three columns in the table 5. In the present example data, there is no case where several track sections in one block partition exceed the limit length. Type 17 indicates that the section passes through a traffic signal or a signal signboard, and type 15 indicates a section division point. The resistance value of the railway ballast is 1.0.

TABLE 5

As can be seen from the above table, in the 2-time division signal odometer, there is no situation that several track sections in one block partition exceed the limit length, and equal division is not needed for the moment, and the position of the division point can be optimized according to the weight coefficient method, and only the position of the division point is adjusted for the block partition in which the sections exceeding the limit length of the track circuit are located, so as to maintain the number of the division points unchanged. Specifically, the specific weight of each section length in the block partition is sequentially calculated by taking the ratio of the length of the block partition to the sum of the limit lengths of the track circuits of the sections in the block partition as a coefficient, the positions of the partition points are adjusted, the optimal matching of the track section length and the limit length of the track circuit is realized, and the optimal partitioned signal machine odometer is formed. Based on the signal odometer after the optimized segmentation, the track circuit limit length check table after the optimized segmentation can be obtained as shown in the following table 6, and the data in the signal odometer after the optimized segmentation corresponds to the first three columns in the table 6. In this example data, type 17 indicates that the section passes through a traffic signal or a signal signboard, and type 15 indicates a section division point. The resistance value of the railway ballast is 1.0.

TABLE 6

As can be seen from the above table, the optimized divided signal odometer still has a block partition exceeding the track circuit limit length section, and a division point needs to be added, and the signal odometer after the division point is added is obtained by dividing again according to the equal division principle. Based on the signal odometer after the division point is added, the track circuit limit length check table after the division point is added is as shown in table 7 below, and the data in the signal odometer after the division point is added is corresponding to the first three columns in table 7. So far, there are no more sections exceeding the limit length of the track circuit, and all the block partitions are divided. Type 17 indicates that the section passes through a traffic signal or a signal signboard, and type 15 indicates a section division point. The resistance value of the railway ballast is 1.0.

TABLE 7

As can be seen from the above table, the signal odometer after the division point is added has no more sections exceeding the limit length of the track circuit, and can meet the actual requirements and complete the division. In practical application, there may be a segment exceeding the limit length of the track circuit in the signal odometer after the division point is added, and the division point adjustment needs to be continuously performed on the block partition where the segment is located until all segments do not exceed the limit length of the track circuit.

In an embodiment, the calculating the track circuit limit length of each track section specifically includes:

Specifically, for each track section, determining the ballastless limit length of the track section based on the track circuit limit length parameter table and the ballastless track parameter of the track section may include: respectively assigning the length of the ballastless roadbed, the length of the ballastless bridge, the length of the ballastless tunnel and the total length of a target ballastless tunnel with the largest proportion in the ballastless tunnels of the track section to the current roadbed length, the current bridge length, the current tunnel length and the total length of the tunnel with the largest proportion; reading the track circuit limit length parameter table to obtain each condition parameter; calling a track limit length calculation module to obtain a ballastless limit length returned by the track limit length calculation module based on the current roadbed length, the current bridge length, the current tunnel length, the maximum occupied tunnel total length and each condition parameter, and taking the ballastless limit length as the ballastless limit length of the track section;

The preset ballastless track resistance can be a preset ballastless track resistance of a ballastless track, and can be 3.0 Ω.

The track limit length calculation module can obtain the limit length of the ballast in the following way:

and searching the track circuit limit length parameter table to obtain the roadbed limit length corresponding to the roadbed condition of the current roadbed length under the ballast resistance, the bridge limit length corresponding to the bridge condition of the current bridge length under the ballast resistance, the tunnel limit length corresponding to the tunnel condition of the current tunnel length under the ballast resistance, and taking the smaller one of the obtained roadbed limit length, bridge limit length and tunnel limit length as the ballast limit length.

Each condition parameter can comprise a roadbed preset value, a first bridge preset value, a second bridge preset value, a first tunnel preset value, a second tunnel preset value and a third tunnel preset value, and the preset conditions in the track circuit limit length parameter table comprise a preset roadbed condition, a first preset bridge condition, a second preset bridge condition, a first preset tunnel condition, a second preset tunnel condition and a third preset tunnel condition; determining the roadbed condition of the current roadbed length, the bridge condition of the current bridge length and the tunnel condition of the current tunnel length based on the obtained current roadbed length, the current bridge length, the current tunnel length, the maximum occupied ratio tunnel total length and the condition parameters, wherein the determining may include:

if the obtained current roadbed length is larger than the first roadbed preset value, determining the roadbed condition of the current roadbed length as a preset roadbed condition; otherwise, determining that the roadbed condition of the current roadbed length is not the preset roadbed condition;

if the obtained current bridge length is larger than the first preset bridge length, judging whether the current bridge length is smaller than a second preset bridge length, and if the current bridge length is smaller than the second preset bridge length, determining that the bridge condition of the current bridge length is the first preset bridge condition; if the current bridge length is not less than the second preset bridge length, determining that the bridge condition of the current bridge length is the second preset bridge condition;

if the obtained current tunnel length is larger than a first preset tunnel value, judging whether the current tunnel length is smaller than a second preset tunnel value, and if the current tunnel length is smaller than the second preset tunnel value, determining that the tunnel condition of the current tunnel length is a first preset tunnel condition; if the occupation ratio of the track section is not less than the second preset tunnel value, judging whether the occupation ratio maximum tunnel total length of the track section is less than a third preset tunnel value, and if the occupation ratio maximum tunnel total length of the track section is less than the third preset tunnel value, determining that the tunnel condition of the current tunnel length is a second preset tunnel condition; and if the current tunnel length is not less than the third preset tunnel value, determining that the tunnel condition of the current tunnel length is the third preset tunnel condition.

The roadbed preset value, the first bridge preset value, the second bridge preset value, the first tunnel preset value, the second tunnel preset value and the third tunnel preset value can be preset according to requirements, for example, the roadbed preset value, the first bridge preset value, the second bridge preset value, the first tunnel preset value, the second tunnel preset value and the third tunnel preset value can be respectively set to be 0, 301, 0, 301 and 2001 according to different influences of the lengths of all track base structures in track sections on the limit length of a track circuit. Thus, the preset roadbed condition, the first preset bridge condition, the second preset bridge condition, the first preset tunnel condition, the second preset tunnel condition and the third preset tunnel condition are respectively: l _ J >0, 301> L _ Q >0, L _ Q > -301, 301> L _ S >0, 2001> L _ S > -301, L _ S > -2001, L _ J representing the current roadbed length, L _ Q representing the current bridge length, L _ S representing the current tunnel length.

The track circuit limit length parameter table can also be in the form of an Excel table. The track type is divided into a ballastless track and a ballasted track, the ballast resistance of the ballastless track can be considered as a single fixed value, for example, the ballast resistance of the ballastless track can be considered as 3.0 omega.km; the ballast resistor of the ballast track can have various value-taking conditions, for example, the value-taking conditions can include four conditions of 3.0 Ω, km, 2.0 Ω, km, 1.0 Ω, km and 0.5 Ω, and the track limit length under different preset conditions when each track basic structure is in each ballast resistor can be preset in a track circuit limit length parameter table. For example, the track circuit limit length parameter table may be as shown in table 9 below.

TABLE 9

In table 3, for JXL _ J1, JXL _ Q1, JXL _ Q2, JXL _ S1, JXL _ S2, and JXL _ S3, roadbed limit length corresponding to the preset roadbed condition (i.e., preset roadbed limit length), bridge limit length corresponding to the first preset bridge condition (i.e., first preset bridge limit length), bridge limit length corresponding to the second preset bridge condition (i.e., second preset bridge limit length), tunnel limit length corresponding to the first preset tunnel condition (i.e., first preset tunnel limit length), tunnel limit length corresponding to the second preset tunnel condition (i.e., second preset tunnel limit length), and tunnel limit length corresponding to the third preset tunnel condition (i.e., third preset tunnel limit length) are respectively represented.

In addition, if the roadbed is provided with no reinforcing steel bar structure below the track line and the concrete bridge with the reinforcing steel bar structure below the bridge track line, for the bridge line, the limit length of the ballast can be determined according to the condition of the ballast resistance in actual use, and if the ballast resistance is lower than the requirement, the limit length of the ballast can be determined according to the actual ballast resistance. The limit length of the ballast of the railway steel bridge line track circuit can be determined according to the steel rail parameter test result. For example, when the ballast resistance is 0.5 Ω. km, the ballast limit length of the track circuit in the bridge section may take 500 m.

Illustratively, a limit length parameter table of a ballast track circuit shown in the following table 10 can be designed in advance, and by searching the limit length parameter table of the ballast track circuit, limit lengths of ballasts of different track structure types in a line can be obtained, wherein the limit length of the ballasts is also the reliable working length of the track circuit of the ballast track line.

Watch 10

For the tunnel part in the section, the polluting effects of the environment on the track bed can be taken into account, in particular for long tunnels. When the tunnel part in the section is larger than 300m, the limit length of the ballast can be determined according to the condition of the ballast resistance in actual use. For example, the ballast limit length of the tunnel part can be obtained according to the following principle:

when the ballast resistance is 3.0 omega.km:

if the length of the tunnel is below 300m, the limit length of the ballast of the tunnel part takes 1200 m;

if the length of the tunnel is within 300-2000 m, the limit length of the ballast of the tunnel part is 1000 m;

and if the length of the tunnel is more than 2000m, the limit length of the ballast of the tunnel part is 800 m.

When the ballast resistance is less than 3.0 and more than or equal to 2.0 omega.km:

if the length of the tunnel is within 300-2000 m, the limit length of the ballast of the tunnel part takes 900 m;

and if the length of the tunnel is more than 2000m, the limit length of the ballast of the tunnel part takes 700 m.

When the ballast resistance is less than 2.0 and more than or equal to 1.0 omega.km:

if the length of the tunnel is below 300m, the limit length of the ballast of the tunnel part takes 700 m;

if the length of the tunnel is within 300-2000 m, the limit length of the ballast of the tunnel part takes 600 m;

and if the length of the tunnel is more than 2000m, the limit length of the ballast of the tunnel part takes 550 m.

When the ballast resistance is less than 1.0 and more than or equal to 0.5 omega.km:

if the length of the tunnel is below 300m, the limit length of the ballast of the tunnel part takes 500 m;

if the length of the tunnel is within 300-2000 m, the limit length of the ballast of the tunnel part takes 450 m;

and if the length of the tunnel is more than 2000m, the limit length of the ballast of the tunnel part takes 400 m.

For each track section, the smaller of the ballasted limit lengths respectively determined by the roadbed, the bridge and the tunnel can be used as the ballasted limit length of the track section.

Illustratively, a ballastless track circuit limit length parameter table shown in the following table 11 can be designed in advance for a roadbed and a bridge type, a ballast resistor of a ballastless track can be fixed to be 3.0 Ω.

TABLE 11

In addition, for a railway steel bridge line, the ballastless limit length of a bridge part can be determined according to a steel rail parameter test result. For the tunnel part in the section, the polluting effects of the environment on the track bed can be taken into account, in particular for long tunnels. When the tunnel part in the section is larger than 300m, the ballastless limit length can be determined according to the condition of ballast resistance in actual use. For example, the ballastless limit length of the tunnel portion can be obtained according to the following principle:

if the length of the tunnel is below 300m, the ballastless limit length of the tunnel part takes 1000 m;

if the length of the tunnel is within 300-2000 m, the ballastless limit length of the tunnel part takes 800 m;

and if the length of the tunnel is more than 2000m, the ballastless limit length of the tunnel part takes 600 m.

For each track section, the smaller of the ballastless limit lengths respectively determined by the roadbed, the bridge and the tunnel can be used as the ballastless limit length of the track section.
