Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, a method for searching a crossing route of a train according to an embodiment of the present invention is provided, where the method includes: s1, carrying out distributed storage on the electronic map according to each line according to the difference of the lines, wherein each line occupies different storage spaces; s2, when the train runs across the line, determining the current line number and the next line number of the train; and S3, searching a corresponding storage space in the electronic map according to the current line number and the next line number of the train, and extracting data information corresponding to the line number from the corresponding storage space.
Based on the background technology, the embodiment of the invention provides a method for storing all lines in a distributed manner when the lines are stored during the operation of a train crossing, namely, the related data of each line are stored independently, so that different storage spaces are occupied. When the train has the line crossing operation, the current line number and the next line number of the train are determined in a certain mode, wherein the current line number of the train refers to the line number of the train currently operated, and the next line number of the train refers to the destination line number of the train to be operated in a line crossing mode. And searching a storage space corresponding to the corresponding line number in the distributed storage electronic map in a targeted manner according to the current line number of the train and the next line number of the crossing, and extracting data information of the corresponding line in the storage space. Wherein the data information of each line number comprises information such as a transponder, a ground equipment element and the like.
In the embodiment of the invention, the data information of each line is stored in different storage spaces in a distributed manner, and the current line number and the next line number of the train are directly positioned in the storage spaces of the current line number and the next line number according to the determined current line number and the next line number during searching.
As a possible implementation manner, the distributed storing of the electronic map according to each line according to the difference of the lines includes: and each line corresponds to the corresponding ground equipment element, and the ground equipment elements are classified and stored according to different types, wherein each line occupies different storage spaces.
It can be understood that the electronic map is distributed and stored according to the different lines, and the vehicle-mounted device searches only a single line or two lines (when the line is to be crossed) in the operation process, and adjusts the line where the vehicle-mounted device is located and the next line which is possibly crossed in real time according to the different operation positions.
When the method is used for specific storage, firstly, a data storage structure is required to be formatted, the same ground equipment elements are sequentially organized according to a certain structural form, secondly, various ground elements are further structured according to the affiliated line numbers, finally, data of different lines are finally structured into a final whole-line network electronic map, namely, each line is separately stored, the ground equipment elements affiliated to each line are stored according to different types, related data of each line occupy different storage spaces, and the data structure of the stored electronic map is shown as follows.
As a possible implementation manner, when the train is operated across the line, a plurality of first transponders are installed on a first section of line of the tie line of the first line and the second line, the first section of line belongs to the first line, the installation line number of the first transponders is the first line, and the line number of the first transponders belongs to the second line; and installing a plurality of second transponders on a second section of line of the connecting line, wherein the second section of line belongs to a second line, the installation line number of the second transponders is a second line, and the line number of the second transponders belongs to a first line.
It can be appreciated that the embodiment of the invention is based on the foundation of the urban rail transit protocol on the CBTC interconnection standard. In fig. 2, there are two operation lines, line a and line B, from which line B the train B002 travels over line a, with a tie line connecting line B and line a between line B and line a. Wherein the first half of the tie line (first section of line) belongs to line B and the second half of the tie line (second section of line) belongs to line a. According to the interconnection standards, the layout of the tie lines between the lines of different manufacturers is generally shown in fig. 3 (the diagram is an enlarged version of the diagonal tie line where the B002 vehicle is shown in fig. 2). The transponders FBA01 and VBA02 are arranged on the line B and are controlled by the ground equipment of the line a, so that the transponders belong to all of the lines a, i.e. the transponders FBA01 and VBA02 have a mounting line number of line B and a line number of a. Transponders FBB01 and VBB02 are arranged on the same line a, and the lines to which the transponders belong are line B, i.e. the mounting line numbers of the transponders FBB01 and VBB02 are a, and the line numbers to which the transponders belong are B.
As one possible implementation manner, when there is a crossing operation of the train, determining the current line number and the next line number where the train is located includes: when the train is not positioned, judging whether the transponder is the first transponder or the second transponder when receiving the information of the transponder; if the transponder is not the first transponder or the second transponder, setting the affiliated line number of the transponder as the current line number of the train; if the transponder is a first transponder or a second transponder, the installation line number of the first transponder or the second transponder is set as the current line number of the train, and the line number of the first transponder or the second transponder is set as the next line number of the train.
It will be appreciated that when the train is not positioned, i.e. the train has not been previously positioned by the transponder, and at this point the transponder message is received, it is determined whether the transponder is a normal transponder or a special transponder, where the normal transponder is a transponder not located on the two-line connection, i.e. a transponder whose installation line number corresponds to the belonging line number; the special transponder is the first transponder or the second transponder, the first transponder and the second transponder are positioned on the connecting lines of the two lines, and the installation line numbers of the first transponder and the second transponder are inconsistent with the affiliated line numbers.
If the transponder is a normal transponder, indicating that the train is not running over the line at this time, the belonging line number (or the installation line number) of the transponder is set as the current line number of the train. If the transponder is a first transponder or a second transponder, the fact that the train runs on the crossing at the moment is indicated, the installation line number of the transponder is set to be the current line number of the train, and the line number of the transponder is set to be the next line number of the train.
When the train is positioned to the current line number, only the next line number of the train is needed to be determined, specifically, the information of the last transponder in the movement authorization range is acquired in real time, and if the transponder is the first transponder or the second transponder, the line number of the transponder is set as the next line number of the train; if the transponder is not the first transponder or the second transponder, no processing is necessary.
When the line number of the train, which belongs to the maximum safe front end, and the line number of the train, which belongs to the minimum safe rear end, are inconsistent and become consistent in the process of the train running across the line, the line number of the train, which belongs to the maximum safe front end, is set as the current line number of the train. When the train runs on the tie line, the line number of the maximum safety front end of the train is inconsistent with the line number of the minimum safety rear end of the train; when the train passes through the tie line, the line number of the train to which the maximum safety front end belongs and the line number of the minimum safety rear end belong are consistent, the fact that the train has already crossed the line is indicated, and the train runs on a single line is changed, the line number of the train to which the maximum safety front end belongs is set as the current line number, and the next line number is cleared. And each cycle sets the line number of the highest security front end of the cycle as the line number of the highest security front end of the previous cycle, and sets the line number of the lowest security front end of the cycle as the line number of the lowest security front end of the previous cycle
In several cases, the implementation codes for determining the current line number and the next line number of the train are as follows:
a number of scenarios in the crossing of trains from line B to line a are described below with reference to fig. 2 and 3.
(a) When the train does not pass through the line B and does not reach the tie line, and is a normal transponder (a transponder which is positioned on the line B but is not positioned on the tie line), the vehicle-mounted device can acquire that the transponder belongs to the line B, so that the current line number of the train can be set as the line B.
(b) The train is not positioned and passes through the FBA01 or VBA02 transponder on the tie line, the vehicle-mounted equipment can acquire that the two transponders belong to the line A, the line B is arranged, the vehicle-mounted equipment can judge that the current line of the train is set as the line B, and the next line number is set as the line A.
(c) When the train has a position that reaches the boundary of the tie line, the transponder before the line boundary is VBB02. But at this time, the in-vehicle apparatus has already established positioning, it is necessarily known that the current line is line B, and therefore only the next line number needs to be set to a.
(d) When the vehicle-mounted equipment judges that the line number of the maximum safety front end of the train is inconsistent with the line number of the minimum safety rear end of the train and is consistent with the line number of the minimum safety rear end of the train, the current line number is required to be set as the line number of the maximum safety front end, the next line number is emptied, and at the moment, the train crossing process is ended and single-line operation on the line A is changed.
When the train is in the crossing operation, the current line number and the next line number to be crossed of the train are determined, the determination of the current line number and the next line number of the train in the crossing operation is solved, and the current line number and the next line number of the train are searched in a distributed storage electronic map in a targeted manner according to the current line number and the next line number of the train, so that the searching efficiency is higher.
