Description

Technical Field

[0001] The invention relates to a train signal control system, and in particular to a train adjustment method, equipment and medium for double-line same-platform transfer. Background Art

[0002] In order to facilitate the transfer of passengers, urban rail transit often uses the same-platform transfer to achieve the transfer service between different lines with large passenger flow. Passengers only need to get off the train of one line and walk to the opposite platform to get on the train of another line, thus completing the transfer service quickly. However, the actual realization of such seamless transfer is currently guaranteed by the coordinated compilation of timetables, with the help of longer station stop time and manual operation of drivers. However, the actual operation of trains may be early or late. Therefore, it places high demands on the relevant operators and the work pressure is also very high.

[0003] How to achieve simultaneous arrival and departure of trains at the transfer station of two lines, thereby alleviating the work pressure of on-site personnel, ensuring the convenience of passengers' transfers and saving a lot of waiting time on the platform has become a technical problem that needs to be solved. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and to provide a train adjustment method, equipment and medium for double-line same-platform transfers, which fully considers factors such as the early and late arrival of trains and the re-adaptation of trains after leaving the line, so as to dynamically complete the synchronous arrival and departure control of trains at transfer stations, as well as the automatic adjustment of trains on time, thereby greatly alleviating the work pressure of on-site personnel, improving the reliability of train control at transfer stations, and more comprehensively ensuring the convenience of passenger transfers and saving a lot of platform waiting time.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] According to a first aspect of the present invention, a method for adjusting trains for dual-line same-platform transfers is provided, the method comprising the following steps:

[0007] Step A, cross-line train operation prediction information interaction process;

[0008] Step B, automatic association process of trains at transfer stations;

[0009] Step C, automatic association process of trains at non-transfer stations.

[0010] As a preferred technical solution, the step A is specifically as follows:

[0011] Step S1, providing a train operation plan information sharing module on the central servers of the two lines;

[0012] Step S2, completing the caching of train operation plan information of the two lines within one hour in the shared module of the two lines and providing a refresh interface;

[0013] Step S3, periodically perform real-time checks on the communication status and the train operation plan information cached on the two lines to ensure that the current information is valid.

[0014] As a preferred technical solution, the sharing module in step S1 is capable of obtaining the planned running time of all trains within the current hour from the existing core logic.

[0015] As a preferred technical solution, the interface in step S2 is used for the central server to automatically refresh the train operation data information in the database after detecting the train arrival point, departure point and section stop information.

[0016] As a preferred technical solution, the step B is specifically as follows:

[0017] Step S4, arranging the arrival and departure of trains on the two current lines in sequence according to the transfer stations;

[0018] Step S5, filtering out the arrival and departure information of each train at the transfer station, and matching the arrival train number;

[0019] Step S6, based on the matching result, the time of simultaneous arrival of the trains at the transfer station is formed, and the departure time of the trains with the same stop time is simultaneously calculated;

[0020] Step S7, calculate the arrival schedule of subsequent trains within the current hour; at the same time, according to the adjustment of the transfer station, calculate the arrival and departure times of all subsequent stations of the train, and finally calculate the arrival and departure points of all trains on the two lines within the current hour.

[0021] As a preferred technical solution, in step S4, the transfer station is used as an information extraction node to screen out the arrival and departure information of each train at the transfer station, and an evaluation is performed based on the number of trains in the current time period to select lines with more train stops as basic fixed reference data.

[0022] As a preferred technical solution, in step S5, the arrival and departure points of one of the lines at the transfer platform are taken as the basis, and the arrival and departure points of the other line at the transfer platform are matched with the trains with the shortest time difference, so as to realize the "magnetic" following of the two lines.

[0023] As a preferred technical solution, the matching needs to satisfy the requirement that the time is less than the maximum stop time of the train at the transfer station.

[0024] As an optimal technical solution, the magnetic attraction process is specifically as follows: calculate the number of trains passing through the transfer station within the current hour, and through comparison, select the train arrival and departure points of the lines with a larger number of trains as the fixed reference system, and select the lines with a smaller number of trains as the trains participating in the adjustment.

[0025] As a preferred technical solution, the adjustment process is specifically as follows:

[0026] Compare the selected train arrival and departure points with the train arrival and departure points of the fixed reference system one by one; select the train with the smallest time difference as the common arrival and departure train for establishing the same-platform transfer;

[0027] If the current error exceeds the maximum stop time of the current station and is less than the maximum deviation range of the system, it will be adjusted according to the system default maximum stop time without considering simultaneous departure;

[0028] If the current error is within the current maximum stop and the system's maximum deviation range, adjustments will be made based on simultaneous departure. If the arrival times of the two most suitable trains currently exceed the system's maximum deviation range, it is assumed that the current system cannot arrive at the station at the same time, and the original train arrival and departure points remain unchanged.

[0029] As a preferred technical solution, the step C is specifically as follows:

[0030] Step S8, based on the train arrival and departure information recalculated at the transfer station, while ensuring that the transfer station time remains unchanged, the running deviation of other non-transfer station trains is minimized;

[0031] Step S9, automatically adjusting according to the maximum and minimum stop times at non-transfer stations and the maximum and minimum train running speeds in the train section;

[0032] Step S10, feeding back the automatically adjusted train prediction plan to the central server of each line, and the central server prohibits other adjustment algorithms and controls the train according to the currently adjusted train operation plan information;

[0033] Step S11, after each train leaves the transfer station, the calculation information of the transfer station is re-triggered, and the arrival and departure points of the train transfer station are ensured to remain valid through real-time refreshing.

[0034] As a preferred technical solution, the central server promptly notifies the shared module of the corresponding actual train operation information changes after the train operation information changes. The shared module will update the local actual train arrival point status, and for the nodes that have actually occurred, only the subsequent future plans will be adjusted.

[0035] As a preferred technical solution, the sharing module pre-stores basic operation data information of the two lines, including: maximum and minimum station stop time, maximum and minimum interval operation time, number information of each station platform and location of the transfer station.

[0036] As a preferred technical solution, this method preferentially selects one line as the reference coordinate system, which remains unchanged, and the trains of the other line are actively adsorbed to the arrival and departure points of the trains of the first line; the line for selecting the fixed reference coordinate system requires the line with the largest number of trains at the co-linear transfer station as the reference system. If the number of trains passing through is equal, the arrival and departure point of the trains of one of the lines is selected as the reference system by default.

[0037] As a preferred technical solution, this method uses a fixed reference rate to forcibly match the train arrival and departure points of another line to one line within a set adjustable range. Subsequently, the resulting deviation is automatically adjusted with the help of non-transfer platform stop time and section running time, thereby achieving multiple adjustments based on the actual arrival and departure of the trains at each station, and ultimately achieving the two lines arriving at the transfer platform at the same time.

[0038] As a preferred technical solution, the method automatically adjusts the non-transfer platform by adjusting the station stop time of the train and the interval running speed of the train to achieve the final on-time arrival of the train;

[0039] This method controls the real-time nature of information within a configurable update interval, with the maximum interval running time and the maximum train stop time as a real-time effective value;

[0040] This method feeds back the final result to the central server through a set information bit: if the central server detects that the current result has been adjusted, it will no longer adjust it; if it detects that the current method has not been adjusted, the automatic adjustment algorithm of the central server will automatically intervene to ensure that the train arrives on time.

[0041] According to a second aspect of the present invention, there is provided an electronic device, comprising a memory and a processor, wherein a computer program is stored in the memory, and the method described above is implemented when the processor executes the program.

[0042] According to a third aspect of the present invention, there is provided a computer-readable storage medium having a computer program stored thereon, wherein the program implements the method described above when executed by a processor.

[0043] Compared with the prior art, the present invention has the following advantages:

[0044] 1. The difference of the present invention is that it realizes the real-time synchronization and periodic refresh of the train operation plan information of two lines for the first time. In the existing technology, each line is calculated separately without sharing information, so it is impossible to calculate the simultaneous cooperation behavior of trains between the two lines.

[0045] 2. The difference of the present invention is that it introduces a "magnetic attraction algorithm" based on the transfer station and the arrival and departure points of one line. The transfer train on the same platform of another line automatically matches the train of the first line according to its own arrival and departure point error, thereby forming an association relationship between the trains of the two lines. However, the existing independent lines cannot complete this "magnetic attraction" function.

[0046] 3. The present invention is different in that, under the premise of giving priority to the arrival and departure of trains at the same platform, the arrival and departure point information of the current train is taken into account simultaneously, reducing the impact of the coupling of train operation at transfer stations on the punctuality rate of non-coupled stations. By coupling transfer stations and adjusting the gaps at non-transfer stations, the punctual operation of trains on both lines is guaranteed. This calculation and computer-assisted adjustment cannot be completed on existing separately controlled lines.

[0047] 4. The present invention realizes accurate calculation and control of trains on two lines by means of computer-aided calculation, which is more accurate than the existing manual control by drivers, stations and dispatchers in the control center. The present invention also greatly simplifies the workload of relevant personnel, and ensures the operation of trains on two lines through the system, which is more reliable.

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0053] In the operation of urban rail transit, there are some lines with transfers on the same platform, which require trains to arrive at the station at the same time so that two trains can complete the transfer at the same platform. However, due to the actual train operation, trains may be early or late. Relying solely on the arrival and departure of trains on the same platform designed in the timetable and manual guarantees will result in large errors and high work pressure. Therefore, a method is needed to dynamically complete the simultaneous arrival and departure of trains on the two lines, thereby improving the accuracy and reliability of the service and greatly alleviating the pressure on on-site operating manpower.

[0054] The present invention relates to an automatic adjustment method for trains to arrive at a transfer platform and depart from a transfer platform at the same time based on computer automatic adjustment algorithm control. Traditional automatic adjustment of train operation is based on the operation status of the line. The present invention implements a joint adjustment algorithm for the operation of the co-line segment of two lines, dynamically realizes the arrival and departure time control of the train, and combines with the traditional train adjustment algorithm to realize the optimization algorithm for the transfer of trains on the same platform of the two lines. On the one hand, it optimizes the current static control method based on the timetable; on the other hand, it reduces the adjustment pressure of the driver and the dispatcher of the control center, ensuring that the quality of the transfer service of the two lines is improved.

[0055] The present invention provides a train adjustment method for dual-line same-platform transfer, the method comprising:

[0056] The scenario considered in this method is the control of train transfers at the same platform, so that trains from two lines can arrive at the station at the same time, which is convenient for passengers to transfer directly and avoid passengers being stranded in the platform area; Figure 1 and Figure 2 shown.

[0057] The present invention is based on the ability to obtain a real-time predicted train operation timetable for two lines, and controls the operation of trains within one hour to accurately control the operation of trains in the current time period.

[0058] The present invention first needs to identify the information of the transfer stations of the two lines and the basic parameter information of the two lines through configuration, including the maximum / minimum time of the station stop and the maximum / minimum time of the interval operation, so as to process the train operation plan of the two lines within the current three hours received subsequently;

[0059] The external control center needs to promptly notify the module library of the present invention of the corresponding actual train operation information changes after the train operation information changes. This module will update the local actual train arrival and departure point status. For the nodes that have actually occurred, the system will not make adjustments, but only adjust the subsequent future plans;

[0060] The module developed by the present invention automatically starts the magnetic attraction algorithm after receiving the train information update, such as Figure 4As shown, the number of trains passing through the transfer station within the current hour is calculated. By comparison, the train arrival and departure points of the lines with a large number of trains are selected as the fixed reference system, and no adjustment is made to the train arrival and departure times; the lines with a small number of trains are selected as the trains participating in the adjustment.

[0061] Compare the selected train arrival and departure points with the train arrival and departure points of the fixed reference system one by one. Select the train with the smallest time difference as the common arrival and departure train for establishing the same-platform transfer. If the current error exceeds the maximum stop time of the current station and is less than the maximum deviation range of the system, it will be adjusted according to the system default maximum stop time, and simultaneous departure will not be considered. If the current error is within the current maximum stop time and also within the maximum deviation range of the system, it will be adjusted according to simultaneous departure. If the arrival time of the two most suitable trains exceeds the maximum deviation range of the system, it is assumed that the current system cannot arrive at the station at the same time, and the original train arrival and departure points of each train remain unchanged.

[0062] According to the train's scheduled arrival and departure information, the train's arrival and departure time at the transfer station remains unchanged, and the scheduled arrival and departure points of subsequent trains that have not yet run are adjusted according to the train's on-time operation. If the train still cannot resume on-time operation after adjustment, it will remain in the delayed status.

[0063] When the arrival and departure schedules of all trains are adjusted, the current module submits the adjusted train arrival and departure points to the execution unit for train control.

[0064] Before each train docking magnetic attraction algorithm is implemented, this module needs to check the validity and real-time nature of the current plan information. Once the data is found to be expired, the current timetable same-platform transfer algorithm will be immediately disabled.

[0065] The scenario described is based on the requirement of same-platform transfers where trains from two lines arrive at the same platform at the same time. The basic operating data information of the two lines should be available in advance, including: maximum / minimum station stop time, maximum / minimum interval running time, numbering information of each station platform and the location of the transfer station. The system preferentially selects one line as the reference coordinate system, which remains unchanged, and the trains of the other line are actively adsorbed to the arrival and departure points of the trains of the first line; the line that selects the fixed reference coordinate system requires the line with the largest number of trains at the co-linear transfer station as the reference system. If the number of trains passing through is equal, the arrival and departure point of the trains of one of the lines is selected as the reference system by default;

[0066] Through a fixed reference rate, the train arrival and departure points of another line are forcibly matched to one line within a certain adjustable range. Subsequently, the resulting deviations are automatically adjusted with the help of non-transfer platform stop time and section running time, thereby achieving multiple adjustments based on the actual arrival and departure of trains at each station, and ultimately achieving the goal of both lines arriving at the transfer platform at the same time, and ensuring that the adjusted trains can eventually arrive at the turnaround platform on time, without affecting the turnaround operation of subsequent trains.

[0067] This method requires basic information of two lines, all timetable information of trains passing through the transfer station and parameter information of the transfer station that can be adjusted. The automatic adjustment algorithm for non-transfer platforms is to adjust the station stop time of the train and the interval running speed of the train to achieve the final on-time arrival of the train.

[0068] Considering that the adjusted train arrival and departure points of this method will directly affect the online control, the real-time nature of the information is controlled within the configurable update interval. Generally, the maximum interval running time and the maximum train stop time are taken as a real-time effective value. In order to ensure a smooth transition between the entire adjustment algorithm and the automatic adjustment algorithm of a single line, this adjustment algorithm will feed back the final result to the external control module through a specific information bit: if the external control module detects that the current result has been adjusted, it will no longer adjust it. If it is detected that the current algorithm has not been adjusted, the automatic adjustment of the single-line control center is considered an automatic intervention to ensure that the train arrives on time.

[0069] Specific implementation process

[0070] First, the operation mode of the present invention is introduced, which is mainly described as follows:

[0071] The algorithm included in the method is encapsulated in a universal LIB library, and the central server of the existing line needs to provide calling access work according to the requirements of the LIB interface.

[0072] This method includes the address configuration and communication requirements of the corresponding internal communication of the two lines. The central server operation of the two lines on site needs to load the corresponding data configuration, build a local communication group, and realize the basic environment for synchronization of train operation information.

[0073] Once the algorithm library included in this method detects that the local communication group is interrupted and cannot synchronize information, it will temporarily stop the corresponding algorithm. The train plan arrival and departure points called by the central server will remain unchanged and return to the original calling algorithm, and the flag will indicate that the current plan has not been adjusted. The central server will control the train operation according to the original single-line adjustment algorithm.

[0074] The algorithm library included in this method will automatically negotiate to fix the train information of one line as the reference system and the train plan information of the other line as the magnetic system. The central server needs to automatically update the planned operation information of the train within the current hour to the algorithm library based on the train arrival or departure and section parking events. After receiving the arrival and departure information of the train at the transfer station, the algorithm library of this method automatically calculates based on the arrival and departure information of the two lines cached locally.

[0075] After correctly obtaining the train operation information of the two lines, the algorithm library included in this method automatically starts the magnetic attraction algorithm, automatically calculates the matching relationship between the two lines, automatically calculates the synchronous arrival and departure points of the transfer platform, and completes the automatic adjustment of the non-transfer platform. The central server obtains the current train information through the flag bit mark that has been adjusted, and after obtaining the train arrival and departure point information, it directly outputs it to the site to complete the train control, and the local automatic adjustment algorithm no longer performs secondary adjustment calculations.

[0076] The algorithm library of this method will check the real-time nature of the current information in real time. If the locally cached information has not been effectively refreshed for a certain period of time, the current algorithm library will be disabled by default and the current algorithm will be suspended. Once the train plan information is updated, the corresponding algorithm will be re-enabled immediately.
