Detailed Description
The present invention will be described in detail with reference to specific examples. The following examples will aid those skilled in the art in further understanding the present invention, but are not intended to limit the invention in any manner. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
In the application process of the LKJ2000 device, a user finds that the existing line data organization and application cannot meet the application requirements in the following operation scenes: (1) When the train starting station starts, the driver cannot select and use the side track data of the starting station. (2) When a train is started at a train starting station, a starting opposite-marking point is positioned in a long chain, and effective temporary speed limit revealing data are prestored in an LKJ2000 type train operation monitoring device (hereinafter, LKJ2000 type device), the LKJ2000 type device cannot correctly use the temporary speed limit revealing data.
Generally, a railway line has a plurality of stations, an inbound signal machine is used for controlling the inbound of a train, and an outbound signal machine is used for controlling the outbound of the train. Many signal machines exist between stations, a line section between the stations is divided into a plurality of sections, and a plurality of trains are allowed to run in the same section. Based on the spatial distribution of incoming signal machines, outgoing signal machines and signal machines passing different types, the basic line data are constructed by combining the surveying and mapping data of railway lines, and the existing line data organization mode is shown in table 1. And adding the speed limit data of the section, curve data, line gradient data, crossing, bridge, tunnel, mileage mutation and other railway line data between serial numbers 1 and 2, serial numbers 3 and 4, serial numbers 5 and 6, and serial numbers 6 and 7 according to the actual condition of the railway line.
When a train starts at a starting station, the LKJ2000 type device needs to acquire the current position information of the train, determine the current position of the train and provide a coordinate origin for the correct operation of the control function of the train. In the conventional positioning method, the LKJ 2000-type device positions the start address of the origination station call data at serial number 4 in table 1 based on a temporary control parameter input by a driver. After the driver operates the train to align the train, the LKJ 2000-type device calls the data sequentially from the serial number 4 of table 1 and determines that the train is currently located at the outbound signal depicted by the serial number 4. Starting from number 4 in table 1, the LKJ2000 type device sequentially calls data after number 4 based on the real-time position information of the train. Because the LKJ2000 type device calls the data after the serial number 4 according to the train real-time position information sequence, the LKJ2000 type device cannot acquire the lateral line track data of the starting station, and a driver cannot select correct track data. In addition, the outbound traffic signal data described by the number 4 is station main line outbound traffic signal data, which causes the LKJ2000 type device to perform a beacon operation, organize and use line data, in accordance with the start station main line outbound traffic signal. Thus, existing line data organization and methods of use result in the initiation of a drive: 1) The mental state of a driver is highly centralized, degradation alarm control in the driving benchmarking process is frequently processed, and the workload of the driver is increased; 2) The LKJ2000 type device cannot perform accurate turnout control according to the starting station stock road data, and can only perform outbound speed limit control according to the worst speed limit information described in the station information, so that the station operation efficiency is low.

The railway uses kilometer marks to calibrate the position of the railway line, for example, the position information represented by K100+800m is 100km +800m. Theoretically, the kilometer of a newly-built railway line is continuously changed, and the kilometer scale is decreased for the uplink (the direction of the train approaching to Beijing) and increased for the downlink (the direction of the train departing from Beijing). However, in the process of using the railway line, the operation units inevitably modify the railway line. Extension or shortening of a section of a railway line can affect the kilometer scale system of an existing line, resulting in discontinuity of the existing kilometer scale. For example, in the range of kilometer scale K1000+000 m-K1000 +800m, the original railway line with the length of 800m is removed, and a section of railway line with the length of 1km is newly built at the position of K1000+000 m. The end point of the newly-built railway line is still K1000+800m. If the original kilometer sign system is still used, the length of the newly-built railway line can express errors, and if the existing kilometer sign system is changed, all affected kilometer signs of the railway line need to be modified, so that the workload is huge. In order to solve the problems, mileage mutation information is added in a basic line data structure, and the influence of railway line modification on an original kilometer marking system is expressed under the condition that the original kilometer marking system is not changed. The discontinuous positions of the mileage of the line caused by line reconstruction, retest and other reasons are defined as broken chains, and the mileage information of which the difference between the two mileage before and after the broken chains is smaller than the actual length is defined as a long chain. In the existing basic route data structure, the mileage mutation information has only the following elements, including: new line number, serial number, new kilometer post, crossing distance, trend marker, long chain marker, up link marker, down link marker, three line marker, and reverse marker. When the length of the long chain is more than 1 kilometer and the starting station is located in the long chain, after the train is started to align the mark in the starting station, the LKJ2000 device calls data from the serial number 3 of the table 2, and the long chain starting point cannot be obtained according to subsequent mileage mutation information.
The temporary speed limit disclosure data is a temporary speed limit scheduling command, and the LKJ2000 type device performs temporary speed limit at a predetermined point within a required time range according to the scheduling command. If valid temporary speed limit revealing data exist in the current section, after the train starts to drive, when the LKJ2000 type device matches the temporary speed limit revealing data, the starting point and the end point of the temporary speed limit section cannot be correctly determined, and further the temporary speed limit is controlled more, less or even not, so that the train is over-speed in the temporary speed limit section, and safety accidents are caused.
Table 2: existing line data organization example 2
Aiming at the two data application defects described above, the invention provides the departure function of the departure station according to the lateral line track by 1) optimizing the line data positioning departure station address mapping mechanism, improves the convenience of driver departure and benchmarking, improves the station operation efficiency, realizes more accurate departure and departure turnout control and increases the train operation safety. 2) Two elements of a long-chain starting point and a long-chain length are added in the mileage mutation information data, and according to information such as the long-chain starting point, the long-chain length, the long-chain sequence number and the like in the mileage mutation information, the relative position relation between the current kilometer post and the temporary speed limit starting point and the temporary speed limit end point in the temporary speed limit disclosure information is compared, so that the correct temporary speed limit starting point, the correct temporary speed limit end point and the correct temporary speed limit length are determined, the operation efficiency is improved, and the driving safety is ensured.

Fig. 3 illustrates a departure control flow of the origin station according to a side track, the LKJ2000 type device implements control for obtaining side track data according to the steps (1) to (3) of the line data organization and operation method of the present invention, and implements side exit control according to the step (4) of the line data organization and operation method of the present invention. Fig. 4 illustrates a temporary speed limit disclosure control flow diagram of a long-chain-marker-valid origin station, where an LKJ 2000-type device implements acquisition of temporary speed limit control data according to the line data organization and application method step (5) 1) of the present invention, determines a temporary speed limit control start point and a temporary speed limit control end point according to the line data organization and application method steps (5) 2) to (5) 6) of the present invention, and performs temporary speed limit control according to the line data organization and application method step (5) 7) of the present invention.
Example one
In the degraded mode, after the driver inputs effective temporary control parameters, the LKJ 2000-type device changes the first address of the calling data of the starting station from the serial number 4 of the outbound signal machine in table 1 to the first data element address after the inbound signal machine, namely, the calling data starts from the serial number 3 track data in table 1.
The LKJ 2000-type device provides a starting station side lane data selection function when recognizing that the starting station has side lane data.
After the driver selects the side strand track number, the LKJ2000 type device calls corresponding side strand track data, corrects the position of the outbound signal machine according to the side strand track data, and determines the range of the turnout area and the turnout speed limit according to the side strand track data.
And the driver performs driving and target-marking operation at the outbound signal machine of the side track, enters a complete monitoring mode, and performs accurate side track departure control according to the determined range of the turnout area and the turnout speed limit.
Example two
The long chain data defects of the prior art will be described below by specific examples.
And setting long-chain data according to 'railway line mileage broken chain setting and management temporary travel stipulation'. The starting point of the long-chain data can be arranged at the whole kilometer scale and can also be arranged at the whole hundred meter scale. The arrangement of the long chain at the whole kilometer scale and the arrangement of the long chain at the whole hundred meter scale may generate different relative position relationships.
The structure of the long chain 1 is shown in FIG. 1. The starting point of the long chain 1 is located at the whole kilometer scale, the kilometer scale trend of the line is increased, a long chain exists 1km behind the kilometer scale K1+000m, and the length is 2km. The long chain 1 data information is schematically shown in table 3.
TABLE 3 Long chain 1 data information
The structure of the long chain 2 is shown in FIG. 2. The starting point of the long chain 2 is located at the whole hectometer standard, the kilometer scale trend of the line is increased, a long chain exists 700m behind the kilometer scale K1+000, and the length is 2km. The data information for Long chain 2 is shown schematically in Table 4.
TABLE 4 Long chain 2 data information
| Serial number | Data type | Over a distance | Kilometer post | Long chain marker | |
| 1 | … | … | K1+000 | Invalidation | 0 |
| 2 | |
700m | K1+700a | Is effective | 0 |
| 3 | |
1000m | K1A+000a | Is effective | A |
| 4 | Mileage mutation information 3 | 2000m | K1B+000a | Is effective | B |
| 5 | Mileage mutation information 4 | 2700m | K1+700 | Invalidation | 0 |
In FIG. 1, the metric K1+900m is located to the left of the metric K1A +000 a. In FIG. 2, the kilometer sign K1+900m is located to the right of K1A +000 a.
The kilometer scale for the starting benchmarking points is a long-chain kilometer scale as described in table 3. Assume that the kilometer of the departure benchmarks is labeled as K1A +500a. If the current section has effective temporary speed limit disclosure data, the starting point of the temporary speed limit is K1+800, and the end point of the temporary speed limit is K2+100. According to the long-chain 1 structure, after the LKJ2000 type device is started and subjected to benchmarking, temporary speed limit control is started immediately, the starting point of the temporary speed limit is K1A +500a, the end point of the temporary speed limit is K2+100, and the length of the temporary speed limit is 1600m. According to the long-chain 2 structure, after the LKJ2000 type device is started to mark, the device runs for 1800m and then starts temporary speed limit control, the starting point of the temporary speed limit is K1+800, the end point of the temporary speed limit is K2+100, and the length of the temporary speed limit is 300m. Because the mileage information does not have a long-chain starting point, the LKJ2000 type device cannot determine whether the temporary speed limit data is matched according to the long-chain 1 structure or the long-chain 2 structure, and therefore the temporary speed limit revealing data is used wrongly.
In order to understand the design of the present invention, the solution to the problem will be described below with a specific example.
1) The kilometer standard trend increases. A long chain exists 1km behind the kilometer sign K1+000, and the length is 2km. The structure of Long chain 1 is shown in FIG. 1, and the data information of Long chain 1 is shown in Table 5.
TABLE 5 Long chain 1 data information
The kilometer post for the start benchmarking points is a long-chain kilometer post, as described in table 5. Assume that the kilometer of the departure benchmarks is labeled as K1A +500a. If the current section has effective temporary speed limit disclosure data, the starting point of the temporary speed limit is K1+800, and the end point of the temporary speed limit is K2+100. The LKJ2000 device determines a temporary speed limit starting point, a temporary speed limit end point and a temporary speed limit length according to the following steps:
after the start of the vehicle is aligned, the LKJ2000 device determines that the kilometer of the start of the vehicle is aligned to be K1A +500a.
The LKJ2000 device takes a long chain starting point of K2+000 and a long chain length of 2km, and takes the long chain starting point as a reference kilometer scale.
The LKJ2000 type device calculates the position of the driving benchmarking point kilometer post relative to the long-chain starting point kilometer post according to the kilometer post trend, the driving benchmarking point kilometer post, the kilometer post serial number, the mileage mutation information, the long-chain starting point kilometer post and the long-chain length, and the crossing distance represents the position. The crossing distance of the driving target point kilometer sign crossing the long-chain starting point kilometer sign is 1= (K1A +500 a) - (K1A +000 a) =500m.
The LKJ2000 type device calculates the position of the temporary speed limit starting point kilometer post relative to the long-chain starting point kilometer post according to the kilometer post trend, the temporary speed limit starting point kilometer post, the mileage mutation information, the long-chain starting point kilometer post and the long-chain length, and the position is expressed by the crossing distance. The crossing distance of the temporary speed limit starting point kilometer post crossing the long-chain starting point kilometer post is 2= (K1 + 800) - (K2 + 000) = -200m.
The LKJ2000 type device calculates the position of the temporary speed limit end point kilometer post relative to the long-chain start point kilometer post according to the kilometer post trend, the temporary speed limit end point kilometer post, the mileage mutation information, the long-chain start point kilometer post and the long-chain length, and the position is expressed by the crossing distance. The crossing distance of the temporary speed limit end kilometer crossing the long-chain start kilometer crossing is 3= (K2 + 100) - (K2 + 000) +2000m =2100m.
And judging the relative position relation of the driving benchmarking point kilometer post, the temporary speed limit starting point kilometer post and the temporary speed limit terminal point kilometer post according to the crossing distance 1, the crossing distance 2 and the crossing distance 3. The temporary speed limit starting point is positioned on the left side of the driving opposite marking point, and the temporary speed limit terminal point is positioned on the right side of the driving opposite marking point. The LKJ2000 device takes a starting and marking point as an actual temporary speed limiting starting point and a temporary speed limiting end point as an actual temporary speed limiting end point.
And calculating the length of the temporary speed limit interval. The temporary speed-limit section length = over distance 3-over distance 1=2100m-500m =1600m.
2) The kilometer standard trend increases. A long chain exists 700m behind the kilometer sign K1+000, and the length is 2km. The structure of Long chain 2 is shown in FIG. 2, and the data information of Long chain 2 is shown in Table 6.
TABLE 6 Long chain 2 data information
The kilometer scale for the starting benchmarking points is a long-chain kilometer scale as described in table 6. Assume that the kilometer of the driving opposite-to-marking point is marked as K1A +500a. If the current section has effective temporary speed limit disclosure data, the starting point of the temporary speed limit is K1+800, and the end point of the temporary speed limit is K2+100. The LKJ2000 device determines a temporary speed limit starting point, a temporary speed limit end point and a temporary speed limit length according to the following steps:
after the start of the vehicle is aligned, the LKJ2000 type device determines that the kilometer of the start of the vehicle is aligned to be K1A +500a.
The LKJ2000 device obtains a long chain starting point of K1+700 and a long chain length of 2km, and uses the long chain starting point as a reference kilometer scale.
The LKJ2000 type device calculates the position of the driving benchmarking point kilometer sign relative to the long-chain starting point kilometer sign according to the kilometer sign trend, the driving benchmarking point kilometer sign and the kilometer sign serial number, the mileage mutation information, the long-chain starting point kilometer sign and the long-chain length, and the position is represented by the crossing distance. The crossing distance of the driving target point kilometer sign crossing the long-chain starting point kilometer sign is 1= (K1A +500 a) - (K1A +000 a) + (1000 m-700 m) =800m.
The LKJ2000 type device calculates the position of the temporary speed limit starting point kilometer post relative to the long-chain starting point kilometer post according to the kilometer post trend, the temporary speed limit starting point kilometer post, the mileage mutation information, the long-chain starting point kilometer post and the long-chain length, and the position is expressed by the crossing distance. The crossing distance of the temporary speed limit starting kilometer post over the long-chain starting kilometer post is 2= (K1 + 800) - (K1 + 700) +2000m =2100m.
The LKJ2000 type device calculates the position of the temporary speed limit end point kilometer post relative to the long-chain starting point kilometer post according to the kilometer post trend, the temporary speed limit end point kilometer post, the mileage mutation information, the long-chain starting point kilometer post and the long-chain length, and the position is expressed by the crossing distance. The crossing distance of the temporary speed limit end kilometer crossing the long-chain start kilometer crossing 3= (K2 + 100) - (K1 + 700) +2000m =2400m.
And judging the relative position relation of the driving benchmarking point kilometer post, the temporary speed limit starting point kilometer post and the temporary speed limit terminal point kilometer post according to the crossing distance 1, the crossing distance 2 and the crossing distance 3. The temporary speed limit starting point is positioned on the right side of the driving opposite marking point, and the temporary speed limit terminal point is positioned on the right side of the driving opposite marking point. The LKJ2000 type device uses the temporary speed limit starting point as the actual temporary speed limit starting point, and the temporary speed limit end point as the actual temporary speed limit end point.
And calculating the length of the temporary speed limit interval. The temporary speed-limit section length = over distance 3-over distance 2=2400m-2100m =300m.
Therefore, no matter whether the long-chain structure 1 or the long-chain structure 2 exists, the temporary speed limit starting point, the temporary speed limit end point and the temporary speed limit length can be correctly confirmed, and correct temporary speed limit disclosure control is carried out.
According to the detailed description of the first embodiment and the second embodiment, it can be known that the above-mentioned line data organization and application method have general applicability. The line data organization and application method solves the problem of low operation efficiency caused by the fact that starting and driving can not select a lateral line, and meanwhile, the workload of a driver is reduced to a great extent. On the other hand, the problem that the stations in the long-chain data start to drive and temporarily limit the speed to reveal and match is solved. The LKJ2000 device correctly determines the starting point and the end point of the temporary speed-limiting section according to the line data organization and the application method, solves the problems of more control, less control and even no control of the temporary speed limit, and completely avoids the potential risk of safety accidents caused by the overspeed of the train in the temporary speed-limiting section.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
