Description

Train route plan loading method, device, equipment and storage medium Technical Field

[0001] The present invention relates to a train operation data loading method, and in particular to a train operation line plan loading method, device, equipment and storage medium. Background Art

[0002] In the Train Autonomous Operation System (TACS) based on train-to-train communication, the train has the ability to operate autonomously. It can obtain the train operation plan from the central control system before operation and store it locally. The train then autonomously triggers and processes the route according to the operation plan and finally departs.

[0003] Operational plans are generally multi-path plans, which typically mean that when turning back, you can choose to turn back at either the up or down platform. This gives the train two options for the next platform before the turning platform, which is crucial information in operational plans.

[0004] A running line is an operational plan without arrival and departure times. Trains stop at each station according to the default stop time. If the running line is connected end to end, trains can continue to run. A running line can be divided into multiple running segments. Each running segment contains at least the starting platform, the terminal platform, and the path from the starting platform to the terminal platform. Some operating directions even have a protective section outside the terminal platform. Each running segment also needs to have a link relationship, including the previous running segment and the next running segment. If there are multiple paths, there may be multiple corresponding next running segments or previous running segments.

[0005] Therefore, the amount of data in the train route plan is very large. When the train receives the route plan from the central control system, the excessive amount of data will result in a long waiting time for transmission and occupy a lot of local storage, which will affect the availability and stability of the system.

[0006] Summary of the Invention

[0007] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a train route plan loading method, device, equipment and storage medium, compress the amount of data received by the train, reduce the pressure on the communication bandwidth when the train runs autonomously, and thus ensure the stability of the train control system.

[0008] In a first aspect, the present invention provides a method for loading a train route plan, wherein the train route has multiple sections, comprising the following specific steps:

[0009] Step S1: receiving compressed route data sent by a central control system, wherein the compressed route data omits an uplink route, a downlink route, and an alternative route corresponding to each route segment;

[0010] Step S2: calculating the uplink section, downlink section and alternative section of each section according to the compressed operating line data, and obtaining original operating line data according to the compressed operating line data, the uplink section, downlink section and alternative section;

[0011] Step S3: Controlling the train running according to the original running line data.

[0012] In one embodiment, in step S2, the compressed running line data includes a section identification code, a starting platform, a terminal platform, and a section direction of each section, and the calculation method of the uplink section and the downlink section includes:

[0013] Step S21: selecting any road section in the compressed running line data as the current road section, and determining whether the starting platform of the other road section is the same as the ending platform of the current road section.

[0014] Step S22: If the starting platform of the other road section is the same as the ending platform of the current road section, then the other road section is set as the downlink section of the current road section, and the current road section is set as the uplink section of the other road section;

[0015] Step S23: traverse the selected sections in the compressed running line data until all selected sections have a downlink section or an uplink section. If a section in the compressed running line data has neither an uplink section nor a downlink section, the train sends an alarm to the central control system and rejects the compressed running line data.

[0016] In one embodiment, the step S22 further includes the following specific steps:

[0017] If only one other road segment has the same starting platform as the ending platform of the current road segment, then directly set the other road segment as the downlink road segment of the current road segment, and set the current road segment as the uplink road segment of the other road segment;

[0018] If the starting platform of multiple other road sections is the same as the ending platform of the current road section, determining whether the road sections of the multiple other road sections have the same direction;

[0019] If the directions of the multiple other road sections are different, only the other road sections with the same direction as the current road section are set as the downlink sections of the current road section, and the current road section is set as the uplink section of the downlink section;

[0020] If the directions of the multiple other road sections are the same, the multiple other road sections are set as downlink sections of the current road section, and the current road section is set as an uplink section of the multiple downlink sections.

[0021] In one embodiment, in step S2, the method for calculating the candidate road section includes:

[0022] Find a road segment with multiple downlink segments, and set the multiple downlink segments as alternative segments for each other;

[0023] The downlink sections of the plurality of road sections that are mutually candidate sections are searched and compared. If the downlink sections of the plurality of road sections that are mutually candidate sections are different, the downlink sections are set as mutually candidate sections.

[0024] In one embodiment, in step S2, the method for calculating the candidate road section includes:

[0025] Find a road segment with multiple uplink sections, and set the multiple uplink sections as alternative sections for each other;

[0026] Search and compare the uplink sections of multiple sections that are mutually candidate sections. If the uplink sections of the multiple sections that are mutually candidate sections are different, set the above-mentioned uplink sections as mutually candidate sections.

[0027] In one embodiment, in step S1, the compressed running line data further includes the path from the starting platform to the terminal platform of each section and the protection section.

[0028] In one embodiment, step S3 includes the following specific steps:

[0029] Preset the loading time of original running line data;

[0030] Comparing the running time of step S2 with the loading time, if the running time of step S2 is greater than the loading time, determining whether the original running line data is complete;

[0031] If the original running line data is incomplete, the train sends an alarm to the central control system and stops the train running;

[0032] If the original running line data is complete data, the train is controlled to travel according to the original running line data.

[0033] In a second aspect, the present invention provides a train loading device, which is applied to an onboard device, wherein the onboard device is installed on a target train and includes:

[0034] A receiving module, configured to receive compressed route data sent by a central control system, wherein the compressed route data omits an uplink route, a downlink route, and an alternative route corresponding to each route segment;

[0035] a calculation module, configured to calculate an uplink section, a downlink section, and an alternative section of each section according to the compressed operating line data, and obtain original operating line data according to the compressed operating line data, the uplink section, the downlink section, and the alternative section;

[0036] Control module: used for controlling the running of the train according to the original running line data.

[0037] In a third aspect, the present invention provides an in-vehicle device, comprising: a processor and a memory, wherein the memory stores machine-readable instructions executable by the processor, and when the in-vehicle device is running, the machine-readable instructions are executed by the processor to perform the following steps:

[0038] Step S1: receiving compressed route data sent by a central control system, wherein the compressed route data omits an uplink route, a downlink route, and an alternative route corresponding to each route segment;

[0039] Step S2: calculating the uplink section, downlink section and alternative section of each section according to the compressed operating line data, and obtaining original operating line data according to the compressed operating line data, the uplink section, downlink section and alternative section;

[0040] Step S3: Controlling the train running according to the original running line data.

[0041] In a fourth aspect, the present invention provides a computer-readable storage medium having a computer program stored thereon, which executes the steps of the following method when executed by a processor.

[0042] Step S1: receiving compressed route data sent by a central control system, wherein the compressed route data omits an uplink route, a downlink route, and an alternative route corresponding to each route segment;

[0044] Step S3: Controlling the train running according to the original running line data.

[0045] Compared with the prior art, the present invention has the following advantages:

[0046] 1. In the present invention, when the central control system sends data to the train, it only sends compressed route data, omitting the uplink section, downlink section, and alternative section in the route data. The train then calculates the uplink section, downlink section, and alternative section based on the compressed route data to obtain the original route data. This further shortens the time it takes to receive the train route plan, reduces the pressure on the communication bandwidth during autonomous train operation, and improves the availability and stability of on-board equipment.

[0047] 2. The train restores the uplink, downlink and alternative sections of each section by comparing the starting platforms, terminal platforms and section directions in different sections, effectively reducing the train recovery cycle, improving the train operation control efficiency, and at the same time improving the stability of on-board equipment.

[0069] The vehicle-mounted device 100 in this embodiment can be used to execute each step in each method provided in the embodiments of the present application. The implementation process of the train control method is described in detail below through several embodiments.

[0070] Example 2

[0071] Please refer to Figures 1 and 2 for flowcharts of a method for loading a train route plan according to an embodiment of the present application. The method for loading a train route plan according to this embodiment can be applied to an onboard device installed on a target train. The specific processes illustrated in Figures 1 and 2 are described in detail below.

[0072] As shown in FIG1 , a method for loading a train route plan according to the present invention includes the following specific steps:

[0073] Step S1: receiving compressed route data sent by a central control system, wherein the compressed route data omits an uplink route, a downlink route, and an alternative route corresponding to each route segment;

[0074] Step S2: calculating the uplink section, downlink section and alternative section of each section according to the compressed operating line data, and obtaining original operating line data according to the compressed operating line data, the uplink section, downlink section and alternative section;

[0075] Step S3: Controlling the train running according to the original running line data.

[0076] In this embodiment, before the target train implements the one-day running line plan, it may first receive the running line data sent by the central control system and store it locally.

[0077] In one embodiment, in step S1, the compressed running line data includes a road section identification code, a starting station, an ending station and a road section direction of each road section.

[0078] Furthermore, in one embodiment, in step S1, the compressed running line data also includes the path and protection section from the starting platform to the terminal platform of each section.

[0079] In this specific embodiment, the starting platform, terminal platform, section direction, path from the starting platform to the terminal platform and protection section information of each section in the compressed running line data can be reflected as the starting platform identification code, the terminal platform identification code, the section direction identification code, the path identification code and the protection section identification code, and the information such as the starting platform, the terminal platform, the section direction, the path and the protection section and their correspondence with the identification code are directly stored in the local list of the train. After the train receives the compressed running line data, it can restore the starting platform identification code, the terminal platform identification code, the section direction identification code, the path identification code and the protection section identification code to the starting platform, the terminal platform, the section direction, the path identification code and the protection section identification code by retrieving the local list, thereby further reducing the file size of the compressed running line data and realizing efficient transmission of the compressed running line data.

[0080] Specifically, as shown in FIG2 , in one embodiment, in step S2 , the method for calculating the uplink segment and the downlink segment includes:

[0081] Step S21: selecting any road section in the compressed running line data as the current road section, and determining whether the starting platform of the other road section is the same as the ending platform of the current road section.

[0082] Step S22: If the starting platform of the other road section is the same as the ending platform of the current road section, then the other road section is set as the downlink section of the current road section, and the current road section is set as the uplink section of the other road section;

[0083] Step S23: traverse the selected sections in the compressed running line data until all selected sections have a downlink section or an uplink section. If a section in the compressed running line data has neither an uplink section nor a downlink section, the train sends an alarm to the central control system and rejects the compressed running line data.

[0084] When the central control system sends data to the train, the running line data can be compressed, and the up section, down section and alternative section in the running line data can be omitted. Then the train calculates the up section, down section and alternative section based on the compressed running line data to obtain the original running line data, which further shortens the reception time of the train running line plan, reduces the pressure on the communication bandwidth when the train is running autonomously, and improves the availability and stability of the on-board equipment 100.

[0085] Furthermore, as shown in FIG2 , in one embodiment, step S22 includes the following specific steps:

[0086] Step S221: If only one other road segment has the same starting platform as the ending platform of the current road segment, then directly set the other road segment as the downlink road segment of the current road segment, and set the current road segment as the uplink road segment of the other road segment;

[0087] Step S222: If the starting platform of a plurality of other road segments is the same as the ending platform of the current road segment, determining whether the road directions of the plurality of other road segments are the same;

[0088] Step S223: If the directions of the other road sections are different, only the road sections with the same direction as the current road section are set as downlink sections of the current road section, and the current road section is set as the uplink section of the downlink section;

[0089] Step S224: If the directions of the multiple other road sections are the same, then the multiple other road sections are set as downlink sections of the current road section, and the current road section is set as an uplink section of the multiple downlink sections.

[0090] Specifically, as shown in FIG2 , in one embodiment, in step S2 , the method for calculating the candidate road sections includes:

[0091] Step S24: searching for a road section with multiple downlink sections, and setting the multiple downlink sections as candidate sections for each other;

[0092] Step S25: searching and comparing the downlink sections of the multiple sections that are candidate sections for each other; if the multiple sections that are candidate sections for each other have different downlink sections, setting the downlink sections as candidate sections for each other.

[0093] Optionally, in one embodiment, in step S2, the method for calculating the candidate road sections includes:

[0094] Find a road segment with multiple uplink sections, and set the multiple uplink sections as alternative sections for each other;

[0095] Search and compare the uplink sections of multiple sections that are mutually candidate sections. If the uplink sections of the multiple sections that are mutually candidate sections are different, set the above-mentioned uplink sections as mutually candidate sections.

[0096] The train restores the up section, down section and alternative section of each section by comparing the starting platform, terminal platform and section direction in different sections, effectively reducing the train recovery time cycle, improving the train operation control efficiency, and improving the stability of the on-board equipment 100.

[0097] For example, in one embodiment, Table 1 shows the compressed route data sent by the central control system, Table 2 shows the original route data loaded by the train, and Figure 6 shows the station map of the route. The process of calculating the original route data based on the compressed route data is as follows:

[0098] Select Section 1 as the current section, and find that the terminal station of Section 1 is the same as the starting station of Section 2 and Section 3;

[0099] It is determined that the directions of section 2 and section 3 are different;

[0100] It is determined that the direction of section 3 is the same as that of section 1, so section 3 is set as the downlink section of section 1, and section 1 is set as the uplink section of section 3.

[0101] Select section 2, section 3, and section 4 in sequence as the current section, and set their uplink section and downlink section in sequence.

[0102] Table 1 Compressed operation line data sent by the central control system

[0103] Table 2 Original running line data loaded by train

[0104] For example, in another embodiment, Table 3 shows the compressed route data sent by the central control system, Table 4 shows the original route data loaded by the train, Figure 7 shows the station map of the route, and Figure 8 shows a schematic diagram of the original route data loaded by the train. The process of calculating the original route data based on the compressed route data is as follows:

[0105] Select segment 10 as the current segment, compare the terminal platform of segment 10 with the starting platforms of other segments, and if the starting platforms of segments 11 and 12 are the same as the terminal platform of segment 10 and the paths of segments 11 and 12 are in the same direction, set segments 11 and 12 as the downlink segments of segment 10, and set segment 10 as the uplink segment of segments 11 and 12;

[0106] Select section 11, section 12, section 13, section 14, and section 15 in sequence as the current section, and set their uplink section and downlink section in sequence.

[0107] Search for sections with multiple downlink sections. Section 10 has two downlink sections, section 11 and section 12. Set section 11 as an alternative section for section 12, and set section 12 as an alternative section for section 11. Search for the downlink sections of sections 11 and 12 respectively. Both sections 11 and 12 have downlink sections (section 13 and section 14), and the two downlink sections are different. Set section 13 as an alternative section for section 14, and set section 14 as an alternative section for section 13. Continue searching for the downlink sections of sections 13 and 14. The downlink sections of sections 13 and 14 are the same, and end the search.

[0109] Table 4 Original running line data loaded by train

[0110] Specifically, in one embodiment, step S3 includes the following specific steps:

[0111] Step S31: Preset the loading time of the original running line data;

[0112] Step S32: comparing the running time of step S2 with the loading time, and if the running time of step S2 is greater than the loading time, determining whether the original running line data is complete;

[0113] Step S33: If the original running line data is incomplete, the train sends an alarm to the central control system and stops the train running;

[0114] Step S34: If the original running line data is complete data, control the train running according to the original running line data.
