Description

Technical Field

[0001] The present invention relates to a rail transit signal system, and in particular to a train timetable matching method, device, equipment and medium based on a shadow mode. Background Art

[0002] After a failure in urban rail transit, the dispatcher at the control center will temporarily change the route by detaining the train to keep the local train running normally. The response to the fault section is to carry out relevant maintenance according to the pre-defined emergency plan, so as to complete the relevant fault repair as soon as possible. After the fault is repaired, the site gradually has the operating conditions of the timetable before the fault, and the dispatcher needs to manually complete the on-site train adjustment to restore the normal timetable operation, and then enter the normal operation mode.

[0003] The current fault recovery mode is that the dispatcher first switches the current operation mode back to the timetable operation mode, and then the system automatically matches the latest train number in real time based on the train arrival information; because the position of the train during the fault is not matched with the timetable, the real-time matching train number has a large error, and the dispatcher then uses manual and diagram adjustments to complete the train number matching of the entire line in sequence until all trains are restored to the timetable control state. This process takes a long time, and the constantly changing train operation timetable also has a great impact on the on-site passengers' expectations of the train arrival time; such a design is unscientific and cannot adapt to the growing needs of the industry.

[0004] After searching, Chinese patent publication number CN112874586A discloses a method for matching intelligent train schedules for urban rail transit. Specifically, the method discloses that the order of all trains is first determined according to the chronological position relationship of all trains; the first train in the order of all trains is selected to match the schedule itinerary, and the subsequent trains are matched to the schedule itinerary in the planned schedule order, and the matching weight is calculated. Then the train order is readjusted, the schedule itinerary is matched, and the matching weight is calculated until all train orders are traversed. Finally, the sum of the weights of all train orders matching the schedule is compared, and the train with the largest sum of weights is selected to match the schedule scenario. The existing patent is a method that directly acts on the online system, calculates weights through deviation cycles, and finally selects a method with the smallest matching weight, that is, the smallest error, to directly form a matching relationship between the train and the timetable. This train matching timetable is generally applicable to normal starting operations, and the timetable is matched according to the order of departure. However, during operation, how to restore to the timetable mode after temporarily adjusting the timetable or recovering from a fault is still a difficulty in the industry. The main difficulty lies in the mismatch between the online trains and the timetable. How to scientifically select a train to be offline or where to arrange an online train is relatively random, and often relies on the daily work experience of the dispatcher, without a good calculation rule. Therefore, during the recovery process, the dispatcher also tries to restore a matching method based on experience without the help of the system, and then manually arranges the train and readjusts the train matching relationship according to the operation situation. The result of these multiple adjustments can only temporarily act on the train, which will make passengers feel that the running time of the train is constantly changing. At the same time, this matching relationship lacks scientific basis, but the dispatcher does not have a suitable environment for pre-simulation.

[0005] Therefore, how to solve the current on-site temporary replacement of timetables and the automatic matching of online trains to the timetable of the day after the on-site operation failure is restored has become a technical problem that needs to be solved. Summary of the invention

[0051] The present invention discloses a train timetable matching method based on shadow mode.

[0052] The method of the present invention specifically comprises the following steps:

[0053] Step S1, building an interface with the online train monitoring system, copying a shadow mode operation system for all trains on the entire line that is consistent with the online system, and realizing the actual tracking operation of all trains on the shadow mode operation system;

[0054] Step S2, the shadow mode operation system uses the train automatic train matching algorithm to complete the association between the online actual running trains and the planned trains in the latest timetable;

[0055] Step S3, the shadow mode operation system provides the dispatcher with a means to adjust the matching between the actual train and the timetable train number, and allows manual modification of the automatic matching result until all trains on the line are operated in the shadow mode according to the subsequent timetable mode;

[0056] Step S4, the matching relationship between the train and the timetable in the line topology diagram of the shadow mode operation system is copied to the online system with one click, the online system switches to the new operation diagram and modifies and operates according to the matching relationship between the actual train and the operation diagram in the shadow mode, and the system returns to normal.

[0057] The step S1 is specifically as follows:

[0058] Step S11, using drawing technology and basic station data, draw a station topology diagram of the entire line as a shadow mode for online monitoring of train operation;

[0059] Step S12: Initialize the train position with the online train monitoring system, draw the train on the shadow mode station map, and complete the simulated operation of the entire line train on the shadow mode station map through periodic train position messages.

[0060] Step S13: by means of an interface with an online train monitoring system, the timetable information of the online system is accessed in real time, and after the user clicks to confirm, the corresponding timetable information is automatically loaded;

[0061] The step S2 is specifically as follows:

[0062] Step S21, according to the loaded timetable information, combined with the position information of the train on the station map in the shadow mode, based on the train near the reversing track, according to the principle of minimizing the time error between the actual train position and the corresponding reversing point in the timetable, automatically complete the automatic matching of the actual train with the corresponding train number in the timetable;

[0063] Step S22, according to the train number of the timetable train, based on the train number automatically matched by the reentry track, according to the sequence of the actual trains, combined with the sequence of the trains in the timetable, the automatic one-to-one matching relationship between the actual trains and the planned trains in the timetable is completed in sequence;

At the same time, it is displayed in a special demonstration in the matching relationship to remind the dispatcher to make manual corrections. Specific embodiments

[0073] like Figure 1 As shown, the existing system architecture that is easily understood by those skilled in the art is used as the basis to clarify the relationship between the newly added shadow mode components and the existing system, which is an interactive relationship; the two software can be deployed on the same hardware device to switch the display; or they can be deployed on different devices to achieve synchronous display;

[0074] like Figure 2 As shown, the software with the shadow mode turned on in detail includes the following components: channel management module 1, timetable management module 2, station display module 3, train map automatic algorithm module 4, train manual matching module 5, train matching management module 6 and train matching linkage module 7;

[0075] The channel management module 1 is respectively connected to the timetable management module 2, the station display module 3 and the train matching linkage module 7 in communication, the timetable management module 2 is respectively connected to the train map automatic algorithm module 4 and the train manual matching module 5 in communication, the station display module 3 is respectively connected to the train map automatic algorithm module 4 and the train manual matching module 5 in communication, and the train matching management module 6 is respectively connected to the train map automatic algorithm module 4, the train manual matching module 5 and the train matching linkage module 7 in communication. The train map automatic algorithm is the key to this invention, and the accuracy of automatic matching is the key point of the present invention to reduce the pressure of manual adjustment and improve the efficiency of on-site adjustment.

[0076] like Figure 2 As shown, the functions between the various functional modes of the shadow mode software of the present invention and the software operation process are introduced, including the following steps:

[0077] Step 100, based on the basic data of the full-line station diagram obtained by the existing train monitoring system, optimization and adjustment are performed, irrelevant elements are deleted, and the station display layout is adjusted to realize the station diagram display configured in the shadow mode;

[0078] Step 101, after the shadow mode system is started, the station display module automatically loads the station map of the shadow mode, and establishes a communication channel with the online system with the help of the channel management module;

[0079] Step 102, according to the channel established with the online system, the position information of the online train is obtained in real time, and simulated and displayed on the shadow mode station map. At the same time, according to the real-time message interaction, the position information of the train is obtained from the online system, the position information display of the train on the shadow mode station map is updated, and the shadow mode train operation is driven by the online system;

[0080] Step 103, with the help of the communication channel, the timetable management module supports the dispatcher to load the operation diagram inside the online system from the shadow mode as the basic information for the subsequent matching plan of the train in the shadow mode system.

[0081] Step 104, in the shadow mode system, the train map automatic algorithm module provides a variety of train automatic train matching algorithms to complete the association between the online actual running trains and the planned trains in the latest timetable; based on the matching results, the train manual matching module provides manual operation management of the association binding and unbinding between the actual trains and the planned trains; it also provides management functions for temporary passenger train number settings and batch setting functions to facilitate operators to manually adjust the train and train number matching operations.

[0082] Step 105, in the shadow mode system, the train map automatic algorithm module provides a variety of automatic train matching algorithms: 1. Priority matching of the nearest train on the reversing track, and sequential backtracking matching algorithm for the remaining trains; 2. Algorithm for matching the nearest platform of the entire line; 3. Automatic matching algorithm for trains with the same direction and destination on multiple routes;

[0083] Step 105, in the shadow mode system, the manual train matching module provides a variety of manual train number matching operations: 1. Manually associate train and train number matching operation; 2. Manually cancel train and train number matching operation; 3. Automatic matching operation of subsequent trains on a one-way line after manually specifying the single-car matching relationship; 4. Manually set the first terminal car operation.

[0084] Step 106, in the shadow mode system, the train matching management module provides the matching relationship data maintenance and management function of the associated train numbers on the entire line, and is the data center of the shadow mode system; at the same time, it simulates the online train tracking operation according to the plan, and provides the function of automatic number change of the planned train after automatic matching; provides the operation tracking function of the planned train and the first-hand car; provides the function of automatically converting the first-hand car to a non-matching train number after running to the end point; provides the function of automatically converting to a non-matching train number after detecting the path deviation.

[0085] Step 107, in the shadow mode system, the train matching linkage module provides a function of importing the actual train into the online system with one click through the channel management module after the actual train and the timetable are reasonably matched, and the timetable is created with the help of the existing functions of the online system; the train numbers are set in batches at one time.

[0086] Step 108, in the shadow mode, these modules each assume different functions, and with the help of mutual calling, collaboration and cooperation, a matching mode combining automatic and manual is realized, decisions are made in the shadow system, and adjustments to the running trains on site are quickly completed, realizing the scientific nature of decision-making and the real-time nature of application.

[0087] like Figure 3 As shown in the figure, in this shadow mode system, the accuracy of the automatic matching algorithm is the most critical algorithm. If the matching is accurate and successful, the manual adjustment work will be reduced a lot. For different operating routes and operating scenarios, the automatic matching algorithm provides multiple algorithms, including: automatic matching deduction mode of turning points, optimal matching mode of train positions, and automatic matching mode of the same destination. Other automatic matching modes will be added in the future according to the scenarios.

[0088] like Figure 3 As shown, the method of automatic train matching of various trains in the present invention is introduced. According to different operating routes and scenarios, different train matching algorithms are provided to the dispatcher, so as to complete the best automatic train matching plan, reduce the pressure of further adjustments on the dispatcher, and shorten the time for fault recovery.

[0089] The following steps are involved:

[0090] Step 201, the turning point automatic matching deduction mode first determines whether the currently loaded schedule diagram belongs to single-route operation, and the timetable management module will feedback whether the current timetable belongs to single-route operation or multi-route operation; because the turning point automatic matching deduction mode is most suitable for a single route, the algorithm will check and remind in advance.

[0091] Step 202, the automatic matching deduction mode of the turning point, if it is confirmed to be a single route, the current automatic matching algorithm will find the turning point of the single route in the timetable, and then according to the trains near the current position of the turning point, take the first train that is about to enter the turning track as the first starting point, match the previous train of the current turning point train of the scheduled train in the timetable, and match the corresponding train number.

[0092] Step 203, the turning point automatic matching deduction mode then follows the up line, and matches the actual train with the planned train one by one according to the sequence of the rear trains and the sequence of the rear trains in the timetable. The actual trains that are not successfully matched will remain unmatched and will be handled manually. For the actual train number that is not matched in the planned train, an alarm will pop up to remind the manual subsequent arrangement of additional trains.

[0093] Step 204: The same algorithm of the automatic matching deduction mode of the turning point is applied to the downline to complete the train matching of the downline, and finally complete the matching of all train relationships.

[0094] Step 205, the train position optimal matching mode is applicable to various complex scenarios, including simple single route operation, multi-route operation, mixed operation of through trains / main station trains / ordinary trains, and other route scenarios;

[0095] Step 206, the train position optimal matching mode first defaults to the train position best matching the current train running on time, and the system completes the matching of the current time point with the nearest scheduled train number in the timetable based on the train arrival information.

[0096] Step 207, train position optimal matching mode: When all trains have completed one arrival and departure, the system automatically matches all train numbers.

[0097] Step 208, the train position optimal matching mode keeps the manual train status for the trains that cannot be matched, and pops up a list prompt for the missing matches of the planned trains, and finally completes the matching of the trains on the entire line.

[0098] Step 209, the same destination automatic matching mode is mainly applicable to the mode of multiple route operation. The system assumes that the turnaround trains of each route are running on time, and then uses the timetable management module to filter out all the turnaround trains that have not turned back at the current time point;

[0099] Step 210, the same destination automatic matching mode then selects the first actual train that is about to enter the reentry track from the actual trains to complete the corresponding matching;

[0100] Step 211, after the same destination automatic matching mode completes the matching of all the return track train numbers, the planned train numbers are matched with the actual train numbers one by one between the return tracks;

[0101] Step 212, after the automatic matching mode of the same destination completes the matching of all the return interval trains, the trains that cannot be matched are kept in the manual train state, and a list prompt is popped up for the missing matching of the planned trains, and finally the matching of the trains of the entire line is completed.
