The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment obtained, belong to the scope of protection of the invention.
Show the schematic flow sheet of an embodiment of definite method of railway information in a kind of railway line of the present invention referring to Fig. 1.In the present embodiment, the method comprises:
101: obtain pending railway line milepost, in wherein said railway line milepost, the milepost of each point is based on a plurality of different mileposts system mark.
In one section continuous railway line, usually there are a plurality of mileposts to be.Such as: exist in certain section of railway track circuit and take the milepost that the milepost that K is sign and the SHZK of take be sign, different milepost signs represent different implications.
102: determine chain rupture and non-chain rupture in described railway line milepost, and the type of described chain rupture and length.
There is sometimes chain rupture in railway line.So-called chain rupture refers to owing to relocating or making a mistake in measurement and cause milepost not conform to actual distance in part, the discontinuous situation of milepost.Analyzed by the milepost to railway line, can judge in railway line and whether have chain rupture.If there is chain rupture, further determine type and the length of each chain rupture.
Wherein, the type of chain rupture comprises two kinds of long-chain and short chains.Long-chain refers to and added one section new milepost in original milepost, usually marks alphabetical A or a are arranged in the milepost of long-chain, in order to long-chain is distinguished.Short chain refers to and deducted one section milepost in original milepost.
Wherein, the length of chain rupture can obtain by engineering data sheet.
103: successively non-chain rupture subscript is marked with to the each point of milepost as the first object point, the milepost of described first object point is converted to preset the first benchmark milepost that milepost is benchmark.
Default milepost system is as benchmark, and this system of milepost as benchmark can adopt in railway line any one milepost system in a plurality of mileposts system, also can adopt the milepost system arranged voluntarily.And then, the milepost of first object point is converted to preset successively the first benchmark milepost that milepost is benchmark.
104: will be positioned at the chain rupture before of first object point as the target chain rupture, and according to type and the length of target chain rupture, the first benchmark milepost of first object point will be converted to the second benchmark milepost.
After the milepost of first object point is converted to the first benchmark milepost, although first object point all adopts the first identical benchmark mileage to be marked, but owing to not having according to chain rupture before first object point, the first benchmark milepost to first object point is processed, thereby the first benchmark milepost of first object point can not reflect the position at first object point place really, thereby the first benchmark milepost after conversion can not be directly used in calculating.The different chain rupture type for the target chain rupture, adopt different fracture processing methods, the first benchmark milepost of first object point is added or deducts to the length of target chain rupture, be converted to the second benchmark milepost with the first benchmark milepost by first object point, thereby make the second benchmark milepost of first object point can reflect really first object point position.
Wherein, when definite target chain rupture, at first the point using the insertion point of whole chain ruptures as first object, convert to preset to incite somebody to action all mileposts of the insertion point of chain rupture the first benchmark milepost that milepost is benchmark to.Compare the first benchmark milepost of chain rupture insertion point and the first benchmark milepost of first object point, thereby determine whether this chain rupture is the target chain rupture.Wherein, the insertion point of chain rupture can obtain by engineering data sheet, for meaning the position of this chain rupture.
105: for the arbitrary long-chain in described chain rupture, successively described long-chain subscript is marked with to the each point of milepost as the second object point, the second benchmark milepost of the insertion point of the described long-chain of foundation and described long-chain insertion point, to the distance of described the second object point, are converted to the second benchmark milepost by the milepost of described the second object point.
After the milepost of the first object point by non-chain rupture is converted to the second benchmark milepost, due to the milepost before changing that is still of the second object point employing on long-chain, thereby the milepost of the second object point on long-chain need to be converted to the second benchmark milepost.
Milepost by the second object point by long-chain is converted to the second benchmark milepost, and making the each point on long-chain is also that the milepost that in employing and non-chain rupture, each point adopts is marked.
Wherein, in the railway milepost, the milepost of the insertion point of long-chain can mean the position that this long-chain inserts.
106: according to the second benchmark milepost of each point in the described railway line milepost after conversion, determine railway information.
After completing conversion, it is mark that the milepost in railway line all is based on same milestone, thereby can determine railway information by the second benchmark milepost of the each point in milepost.This railway information comprises: the information such as railroad track section length, trackside device location, train position, temporary speed limitation zone.Such as: when needs are determined the length of certain section of railway track, utilize the second benchmark milepost of this section of railway track starting point and terminal to subtract each other, can obtain the length of this section of railway track circuit.
In the above-described embodiments, to in the railway line milepost, be converted to preset the first benchmark milepost that milepost is benchmark by the milepost of the first object point in non-chain rupture, and, according to the type and the length that are positioned at the target chain rupture before of first object point, the first benchmark milepost of first object point is converted to the second benchmark milepost.Simultaneously, for the arbitrary long-chain in chain rupture, distance according to the second benchmark milepost of long-chain insertion point and long-chain insertion point to the second object point, the milepost of each point in long-chain is converted to the second benchmark milepost, thereby discontinuous milepost in railway line is converted to the milepost that adopts the second benchmark milepost to be marked, so that the second benchmark milepost after changing by processing is determined railway information.
In actual applications, the mileage target value of pending non-chain rupture railway line may be according to order from small to large mark, for example, the railway line milepost of one section non-chain rupture is labeled as: K218+000, K218+200, K218+300 ... SHZK219+200, SHZK219+300.But pending railway line mileage target value may be also to adopt order from big to small to mark in some cases.For example: a section of railway track circuit milepost is labeled as: K218+900, K218+800, K218+300 ... SHZK219+300, SHZK219+200.
At the benchmark milepost according to default, be, when the milepost of each point in non-chain rupture is converted to the first reference coordinate, in non-chain rupture the order of the first base mileage target value of each point can with untreated before the mark order of mileage target value identical, for example, before untreated, in non-chain rupture, the mileage target value of railway line is order from small to large mark, after conversion on this railway line milepost the first benchmark milepost of each point remain the order mark according to from small to large.
Certainly, when the milepost of each point in non-chain rupture is converted to the first benchmark milepost, in non-chain rupture the order of the value of the first reference coordinate of each point also can with untreated before the reversed in order of mileage scale value.As, untreated before, the mileage target value of railway line is order from big to small mark, after conversion on this railway line milepost the first benchmark milepost of each point according to order mark from small to large.
For the ease of understanding, before untreated, the railway line milepost of one section non-chain rupture is labeled as: K218+900, K218+800, K218+700 ... K218+000 is that example describes.Milepost system according to default, be converted to the first benchmark milepost by this K218+900: 218900.And then, according to the distance of second milepost and previous milepost, the first benchmark mileage that K218+800 is corresponding is designated as 218800, the like.Finally according to default milepost system, the railway line milepost in this section non-chain rupture is converted to successively: 218900,218800,218700 ... 218000.But while considering practical application, employing mode from small to large marks may be convenient, therefore, according to default milepost system, this K218+900 is converted to the first benchmark mileage to be designated as: the first benchmark milepost that 218000 K218+800 are corresponding is 218100, the like, railway line milepost in final this section non-chain rupture is converted to successively: 218000,218100,218200 ... 218900, thus the milepost that makes this section of railway track circuit after conversion is according to order mark from small to large.
After the first benchmark milepost of having determined the first object point in non-chain rupture, also need, according to the type and the length that are positioned at the target chain rupture before of first object point, the first benchmark milepost of first object point to be converted to the second benchmark milepost.Wherein, the type difference of target chain rupture, the mode that the first benchmark milepost is processed also can be different.
