Description

Technical Field

Background

The temporary speed limiting server (Temporary Speed Restriction Server, TSRS) is used for generating speed limiting information aiming at the train when the line which is expected to operate is inoperable (such as construction, disasters, equipment faults and the like), and controlling the train to operate according to the speed limiting information, namely controlling the train to operate at the speed indicated by the speed limiting information in the interval range indicated by the speed limiting information. Therefore, the train can be prevented from running on an inoperable line, and further, the train is prevented from safety accidents.

However, the speed limit information and speed limit instructions generated by the temporary speed limit server need to be transmitted to the train through the transponder.

When the train passes the last transponder before the end point indicated by the speed limit information, the speed limit is ended. Only when the first transponder and the last transponder passed by the train are consistent with the positions of the first transponder and the last transponder included in the speed limit information, the train can be accurately controlled to run according to the speed limit information, and safety accidents of the train are avoided.

To facilitate an understanding of the aspects of the present application, a brief description of related concepts is first presented below.

Temporary speed limit server (Temporary Speed Restriction Server, TSRS): the method is used for generating speed limit information aiming at the train when the line which is expected to run by the train is inoperable (such as construction, disasters, equipment faults and the like), and controlling the train to run according to the speed limit information, namely controlling the train to run at the speed indicated by the speed limit information in the interval range indicated by the speed limit information.

A transponder: a point device for transmitting information to a train on a ground is divided into a passive (fixed) transponder and an active (variable) transponder for providing reliable ground-based fixed information and variable information.

The foregoing is a description of technical terms related to the embodiments of the present application, and is not repeated herein below.

As described in the background, the speed limit information and the speed limit command generated by the temporary speed limit server can be transmitted to the train only by the transponder. I.e. the first transponder after the train passes the start point indicated by the speed limit information, the train starts to run at the speed indicated by the speed limit information. When the train passes the last transponder before the end point indicated by the speed limit information, the speed limit is ended. Only when the first transponder and the last transponder passed by the train are consistent with the positions of the first transponder and the last transponder included in the speed limit information, the train can be accurately controlled to run according to the speed limit information. When the position of the first transponder or the last transponder is miscalculated, this may result in an unparallel train cancellation timing, either earlier or later. The range formed by the first transponder and/or the last transponder is the range in which the temporary speed limit server is connected to the train, in order to send data in this range to the train. In this range, if the temporary speed limit server has no data, the train needs to be logged off at this time, and the train is connected with other temporary speed limit servers. The data interacted with the temporary speed limiting server by the train are platform doors, inter-station data, operation plans and the like. If the train and the temporary speed limiting server cannot be accurately connected, the station door can fail to be linked. The inter-station data and the operation plan are all periodic messages with trigger time, and if the train receives the inter-station data or the operation plan is late, the speed of the train is influenced, and even safety accidents of the train are caused.

In view of this, an embodiment of the present application provides a method for verifying a location of a transponder, which specifically includes: obtaining information of a circuit to be tested, wherein the information of the circuit to be tested comprises a starting point, an ending point and a position of a transponder on the circuit to be tested; generating a plurality of test sequences according to the positions of the transponders on the line to be tested, wherein the test sequences comprise a first transponder and a second transponder, the temporary speed limiting server sends a starting speed limiting instruction to the train through the first transponder, and the temporary speed limiting server sends an ending speed limiting instruction to the train through the second transponder; determining a first distance between the starting point and the first transponder, and determining a second distance between the end point and the second transponder; and when the first distance is the actual distance between the starting point and the first transponder, and the second distance is the actual distance between the ending point and the second transponder, indicating that the position verification of the first transponder and the second transponder is passed.

A plurality of test sequences are generated through the line information to be tested, all the combined conditions which can be used as the first transponder and the second transponder on the line to be tested can be covered, and the first distance and the second distance of the first transponder and the second transponder in the test sequences are determined through the line information to be tested, so that whether the positions of the first transponder and the second transponder in all the test sequences are actual positions or not is verified, the accuracy of the temporary speed limiting server in speed limiting control of the train is improved, and the occurrence of safety accidents can be effectively reduced.

The following describes embodiments of the present application in detail with reference to the accompanying drawings.

The system can realize the centralized management of all-line temporary speed limit commands, and aims to ensure the safety of train control speed limit setting and ensure the smooth implementation of a speed limit plan.

In the embodiment of the present application, the temporary speed limiting server generates speed limiting information according to the line information, so as to control the vehicle-mounted device 130 to operate according to the speed limiting information. The line information includes the start point, the end point, the position of the transponder on the line, the kilometer post information, the broken link information, etc. And the accuracy of the first transponder and the last transponder positions on the line is of paramount importance. Only when the first transponder and the last transponder passed by the train are consistent with the positions of the first transponder and the last transponder included in the speed limit information, the train can be accurately controlled to run according to the speed limit information, and safety accidents of the train are avoided.

The in-vehicle device 130 may be a train automatic protection system (Automatic Train Protection, ATP). The automatic train protection system is used for preventing train overspeed, collision and other dangerous situations possibly occurring during train running. The system will transmit the highest safe speed limit signal to the train through the rail; and continuously compares the actual speed of the train with this highest safe speed. If the actual speed of the train exceeds the highest safe speed, the system instructs the train to make emergency braking so as to avoid overspeed of the train, and simultaneously, the system ensures that the train has enough unoccupied road sections in front of the train to stop the train without collision when the train makes emergency braking.

The transponder 140 is configured to receive the speed limit information sent by the server 120, and forward the speed limit information to the vehicle-mounted device 130.

Next, a method of verifying the location of a transponder will be described in detail with reference to the accompanying drawings. Fig. 3 is a flow chart of a transponder location verification method provided in the present application. The method is applied to a transponder position verification system with a hardware structure shown in fig. 1, and specifically comprises the following steps:

step 310, obtaining the line information to be tested.

The circuit information to be measured is used for the temporary speed limiting server to generate speed limiting information, so that the accuracy of the circuit information to be measured can influence the accuracy of the speed limiting information.

In the embodiment of the application, the line information to be measured comprises a TCC-TSRS interface meter, a transponder position meter, a mileage system information meter and a line mileage broken link detail meter.

The TCC-TSRS interface table includes the name of the line, the line number, the start and end points of the line.

The transponder location table includes location information of all transponders on the line and transponder numbers.

The mileage information table comprises mileage information of a kilometer post conversion point on the line, namely the kilometer post and length (third distance) before the conversion of the kilometer post conversion point, and the kilometer post and length (third distance) after the conversion.

Broken link refers to a place on a line where line mileage is discontinuous due to line transformation and the like. Broken chains are divided into long and short chains. The long chain means that the broken link mileage on the line is overlapped, i.e. the difference between the two mileage before and after the broken link is smaller than the actual length. The short chain refers to the broken link mileage interruption on the line, namely the difference between the two mileage before and after the broken link is larger than the actual length.

The above information of the lines to be tested may be summarized into a line information table, where the line information table is shown in table 1.

TABLE 1

Table 1 is only an example, and specific information included in the line information table, and specific numerical values therein, are not limited.

Step 320, generating a plurality of test sequences according to the positions of the transponders on the line under test.

After the computing equipment acquires the line information to be tested, a plurality of test sequences are generated according to a transponder position table in the line information to be tested.

In one embodiment, the transponder location table is traversed and the numbers and locations of all transponders in the transponder location table that are located after the start of the line under test are added to the first transponder group. And adding the numbers and the positions of all the transponders in the transponder position table before the end point of the line to be tested into a second transponder group.

One transponder is selected from the first transponder group as a first transponder and one transponder is selected from the second transponder group as a second transponder. The selected first transponder and second transponder form a test sequence. From the first transponder group and the second transponder group, a plurality of test sequences can be selected which satisfy a predetermined condition, namely that the position of the first transponder on the line under test is before the position of the second transponder on the line under test. In the embodiment of the application, the temporary speed limiting server sends a speed limiting starting instruction to the train through the first transponder, and the temporary speed limiting server sends a speed limiting ending instruction to the train through the second transponder. In other words, the first transponder is the first transponder on the line under test indicated by the temporary speed limit server. As the train passes the first transponder, the train is operated at a speed indicated by the speed limit information. The second transponder is the last transponder on the line under test indicated by the temporary speed limit server. When the train passes the last transponder, the train is run at a speed indicated by the speed limit information.

The computing device may aggregate a plurality of test sequences corresponding to the plurality of lines to be tested into a test sequence table. The test sequence table is shown in table 2.

TABLE 2

Wherein M < K1< K2< K5< K6< K8< K10< N.

As can be seen from table 2, line 1 has a plurality of test sequences. Namely, the speed limit starts when the train passes through K1, and the speed limit ends when the train passes through K10. Or the speed limit is started when the train passes through K2, and the speed limit is ended when the train passes through K8. And so on.

In the embodiment of the application, the test sequence table includes the combination of all the first transponders and all the second transponders on the line to be tested. Therefore, the combination condition of all the first transponders and the second transponders on the test line can be verified, and the positions of the first transponders and the second transponders are the same as the actual positions of the first transponders and the second transponders when the temporary speed limiting server selects any one of the test sequences.

It should be noted that there are many transponders on the line to be tested, and the train can only speed-limit running when passing through the first transponder indicated by the temporary speed-limiting server, and the speed-limiting will only end when passing through the second transponder indicated by the temporary speed-limiting server.

Step 330, determining a first distance between the start point and the first transponder, and determining a second distance between the end point and the second transponder.

And verifying the position information of the test sequence in the test sequence table through the line information to be tested.

In one embodiment, a first distance between the origin and the first transponder is determined based on kilometer scale information and link failure information between the first transponder and the origin in the test sequence. And determining a second distance between the end point and the second transponder according to kilometer post information and broken link information between the second transponder and the end point in the test sequence.

When there is no kilometer post switching point between the first transponder and the starting point and no broken link between the first transponder and the starting point, determining a first distance according to the position of the starting point and the position of the first transponder.

When no kilometer post switching point exists between the first transponder and the starting point and broken links exist between the first transponder and the starting point, determining the number and the type of the broken links between the first transponder and the starting point according to the broken link information; the first distance is determined based on the location of the origin, the location, the number and the type of the first transponders.

When there is a kilometer post switching point between the first transponder and the starting point and no broken link exists between the first transponder and the kilometer post switching point, determining a first distance according to the third distance, the position of the kilometer post switching point and the position of the first transponder.

When a kilometer sign switching point exists between the first transponder and the starting point and a broken link exists between the first transponder and the kilometer sign switching point, determining the number and the type of broken links between the first transponder and the kilometer sign switching point according to the broken link information; and determining the first distance according to the third distance, the position of the kilometer post switching point, the position, the number and the type of the first transponder.

Similarly, when there is no kilometer post switching point between the second transponder and the destination point and no chain break exists between the second transponder and the destination point, a second distance is determined according to the position of the destination point and the position of the second transponder.

The determination of the first distance of the first transponder at position P from the starting point will be explained below taking fig. 4 as an example.

The position of the starting point of the line to be measured is M, and the position of the ending point is N. The distance between the first kilometer sign switching point and the starting point is L1, the distance between the second kilometer sign switching point and the starting point is L2, and the distance between the second kilometer sign switching point and the ending point is L3.

Wherein d1, d2, d3 may be positive or negative. The positive number indicates that the type of broken chain is long chain and the negative number indicates that the type of broken chain is short chain.

When the first transponder is before the end point after the second kilometer post switch point, the first distance of the first responder is bp+l1+l2.

The computing device may aggregate the first distances and the second distances corresponding to the plurality of test sequences corresponding to the plurality of lines to be tested into a test result table. The test results are shown in Table 3.

TABLE 3 Table 3

After obtaining the test result table shown in table 3, the computing device further needs to verify the first distance and the second distance in the test result table to ensure that the positions of the first transponder and the second transponder in the test sequence are consistent with the actual positions thereof.

Step 340, when the first distance is the actual distance between the starting point and the first transponder, and the second distance is the actual distance between the ending point and the second transponder, indicating that the position verification of the first transponder and the second transponder is passed.

In the embodiment of the application, in order to verify the first distance and the second distance in the test result table, a vehicle-ground wireless communication configuration table is also required to be obtained, and the actual distance between the first transponder and the starting point and the actual distance between the second transponder and the end point in the test sequence can be obtained through the vehicle-ground wireless communication configuration table. The actual distance of the first transponder from the start point is compared to the first distance, and the actual distance of the second transponder from the end point is compared to the second distance.

And when the first distance is the actual distance between the starting point and the first transponder, and the second distance is the actual distance between the ending point and the second transponder, indicating that the position verification of the first transponder and the second transponder is passed. At the moment, when the temporary speed limiting server limits the speed of the train according to the line information to be detected, the position of the first transponder and the position of the second transponder can be accurately obtained, and speed limiting control can be accurately carried out on the train.

And when the first distance is inconsistent with the actual distance between the starting point and the first transponder or the second distance is inconsistent with the actual distance between the ending point and the second transponder, indicating that the position verification of the first transponder and the second transponder is not passed. The first transponder and the second transponder cannot be used to speed limit the train at this time. The positions of the first transponder and the second transponder acquired by the temporary speed limiting server are inconsistent with the actual positions of the first transponder and the second transponder, so that the temporary speed limiting server is inconsistent with speed limiting information on the time speed limiting condition of the train, and the risk of causing safety accidents exists.

The computing device verifies the first distance and the second distance in the test result table to obtain a test result output table as shown in table 4.

TABLE 4 Table 4

The computing device may filter from the test results of table 3 according to the test scenario requirements. Each screening condition can record all information of the line, and the screened test sequences are output according to the requirement, so that table 4 is obtained. The screening conditions may include kilometer post conversion points, broken links, types, lengths, etc.

In summary, a plurality of test sequences are generated through the line information to be tested, all the combined conditions which can be used as the first transponder and the second transponder on the line to be tested can be covered, and the first distance and the second distance of the first transponder and the second transponder in the test sequences are determined through the line information to be tested, so that whether the positions of the first transponder and the second transponder in all the test sequences are actual positions or not is verified, the accuracy of the temporary speed limiting server in speed limiting control of the train is improved, and the occurrence of safety accidents can be effectively reduced.
