Description

Technical Field

[0001] This invention relates to urban rail transit signal control systems, and in particular to a method, apparatus, equipment, and medium for processing terminal station information of a rail transit loop line. Background Technology

[0002] Regular subway lines have fixed terminal stations. Trains perform turnaround operations at the terminal stations, which are divided into pre-station turnaround and post-station turnaround depending on the station type.

[0003] like Figure 1 As shown, for pre-station turnarounds, the train stops at the terminal station platform, opens its doors, and passengers board and alight. The train then closes its doors and departs after completing the turnaround. Therefore, passengers on the train should be notified of the terminal station in advance, and the terminal station must be the station where the turnaround operation takes place.

[0004] like Figure 2 As shown, for a train turning back after a station, the train stops at the platform of the terminal station, opens its doors, and passengers board and alight. After the doors close, the train departs for the turnaround track, where the turnaround and reversal operations are completed. Therefore, passengers on the train should be notified of the terminal station in advance before the train arrives, and the terminal station must be the station where the turnaround and reversal operations will take place.

[0005] For loop lines, there are no pre- or post-station turnaround operations during normal train operation; therefore, it is impossible to calculate the terminal station forecast information through turnaround and end-change operations. For example... Figure 3 As shown, there is no turnaround or relocation operation when the train runs on the loop line. Therefore, the timing and location of the terminal station announcement will be flexible and changeable, and the original calculation principles cannot be used to predict the terminal station information.

[0006] A search revealed that Chinese Patent Publication No. CN115688425A discloses a method for analyzing turnaround capacity based on block time, specifically including: (1) preparing data for line infrastructure, train control model, signaling system, and operation organization parameters; (2) establishing zoning principles according to different systems; (3) establishing block time models for different types of zones based on the signaling system workflow under different systems; (4) constructing train operation plan cycles based on turnaround strategies and train operation ratios; (5) performing asynchronous simulation based on the train operation plan cycles to generate train operation time-distance curves; (6) calling the block time model and simulation data to generate operation plan cycles based on block time windows; (7) establishing a capacity calculation model to calculate the capacity of train operation plan cycles based on block time windows; and (8) outputting the calculation results to obtain the average receiving interval and average departure interval of the train operation plan. However, this existing patent does not involve the calculation process of the terminal station information for loop lines.

[0007] Therefore, given the characteristics of loop lines and their operation, ensuring that ground and onboard PIS screens accurately display train terminal information has become a technical problem that needs to be solved. Summary of the Invention

[0008] The purpose of this invention is to overcome the defects of the prior art by providing a method, equipment and medium for processing terminal station information of a rail transit loop line.

[0009] The objective of this invention can be achieved through the following technical solutions:

[0010] According to a first aspect of the present invention, a method for processing terminal station information of a rail transit loop line is provided. In this method, the ATS system accurately calculates the terminal station information and display timing information of the train based on the operational characteristics of the loop line without turnaround and end-change operations and the train's daily operation plan information, and sends the information to the PIS screen for display.

[0011] As a preferred technical solution, the PIS screen includes a ground-based PIS screen and a vehicle-mounted PIS system. The ATS system sends the calculated information to the ground-based PIS screen and the vehicle-mounted PIS system for display.

[0013] As a preferred technical solution, the ATS system calculates in advance, based on the planned timetable, the last platform and time at which each train will finish its passenger service, and calculates the number of times the train will pass through that platform.

[0014] As a preferred technical solution, the ATS system calculates the destination information of the train and the timing of its display on the onboard PIS screen based on the last platform where passenger service ends, the time when passenger service ends, and the time when the train arrives at and departs from the platform where passenger service ends for the second to last time.

[0015] As a preferred technical solution, the ATS system calculates the destination information of the first, second, third...Nth trains for each station platform in advance according to the planned timetable.

[0017] As a preferred technical solution, the ATS system calculates the terminal station information for both the platform and the train according to the planned timetable. If the terminal station information is not displayed at the right time, the platform PIS screen and the onboard PIS screen will display the direction of "inner loop" or "outer loop".

[0023] As a preferred technical solution, the ATS system calculates in advance the last platform and time for each train to finish its passenger service, based on the planned timetable, and calculates the number of times the train passes through that platform.

[0024] The ATS system calculates the train's destination information and the timing of its display on the onboard PIS screen based on the last platform where passenger service ended, the time when passenger service ended, and the time when the train arrived at and departed the platform on its penultimate day.

[0025] As a preferred technical solution, the ATS system calculates the destination information of the first, second, third...Nth trains for each station platform in advance according to the planned timetable;

[0026] The ATS system uses each platform as a reference and, based on the timetable operation plan, determines whether the first, second, third...Nth train passing through this platform will be the penultimate train to pass through the last passenger platform. It calculates the destination information of all trains planned to pass through each platform and updates it on the platform PIS screen when the train leaves the station.

[0027] As a preferred technical solution, the ATS system calculates the terminal station information for both the platform and the train according to the planned timetable. If the terminal station information is not displayed at the right time, the platform PIS screen and the onboard PIS screen will display the direction of "inner loop" or "outer loop".

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0039] This invention discloses a method for calculating terminal station information of an urban rail transit loop line. The method calculates terminal station information for both the platform and the train, and sends it to the ground and onboard PIS systems at appropriate times.

[0040] The ATS system calculates in advance the last platform and time when each train will end its passenger service based on the train's operation plan, and also calculates the number of times each train passes the last passenger platform. Based on the information of the last passenger platform, the time when passenger service ends, and the time when the train arrives at the last passenger platform on its penultimate day, the ATS system calculates the train's destination information and the timing of its display on the onboard PIS screen.

[0041] Before the train arrives at the last passenger platform on its penultimate journey and before the doors close, the destination information on the onboard PIS screen should display "Inner Loop / Outer Loop"; after the train doors close, the destination information on the onboard PIS screen should be updated to the name of the last passenger platform.

[0042] The ATS system calculates the destination information of the first, second, third, etc., trains that will pass through each platform in advance based on the timetable operation plan. Using each platform as a reference, the ATS system calculates whether the first, second, third, etc., trains scheduled to pass through each platform will be the penultimate train to pass through that platform, calculates the destination information of all trains about to arrive at each platform, and updates the destination information of each train on the platform's PIS screen when it departs the station (due to space limitations on the platform PIS screen, only the information of the first three trains scheduled to pass through the platform may be displayed).

[0043] Before the train arrives at the last passenger platform for the second-to-last time and before it departs, the destination information for that train on the platform's PIS screen should be displayed as "Inner Loop / Outer Loop"; after the train departs, the destination information on the platform's PIS screen should be updated to the name of the last passenger platform.

[0044] This invention is applied to a train automatic control system, which includes an automatic train protection subsystem (ATP), an automatic train operation subsystem (ATO), an interlocking subsystem (CI), an automatic train monitoring subsystem (ATS), a ground-based PIS system, and an onboard PIS system.

[0045] Specific implementation process of this invention

[0046] The ATS system operates according to the timetable schedule, and displays the destination information on the onboard PIS screen, such as... Figure 5The image shows the timetable for a certain train. Before time T1, that is, before the train stops at station B to pick up and drop off passengers and closes its doors, the destination information on the onboard PIS screen should display "Inner Loop / Outer Loop". After time T1, when the train finishes picking up and dropping off passengers at station B and closes its doors, the destination information on the onboard PIS screen will be updated to "Station B".

[0047] According to the timetable operation plan, the ATS system displays the destination information for each train on the platform PIS screen, such as... Figure 5 The image shows the timetable for a certain train. Before time T1, that is, before the train departs after stopping at station B for passenger boarding and alighting, the destination information of the train on the PIS screen of station B should be displayed as "Inner Loop / Outer Loop". After time T1, the train completes passenger boarding and alighting at station B and departs, and the destination information of the train on the PIS screen of station B is updated to "Station B".

[0048] The above is an introduction to the method embodiments. The following describes the solution of the present invention further through device embodiments.

[0053] The ATS system calculates the terminal station information for both the platform and the train according to the planned timetable.

[0054] The ATS system calculates the last platform and time for each train to end its passenger service according to the planned timetable, and calculates the number of times the train passes through that platform. The ATS system calculates the destination information of the train and the timing of its display on the onboard PIS screen based on the last platform for passenger service to end, the time for passenger service to end, and the time when the train arrives at and leaves the platform for the second-to-last time.

[0055] The ATS system calculates the destination information of the first, second, third...N trains for each station platform in advance according to the planned timetable. Based on each platform, the ATS system determines whether the first, second, third...N trains passing through this platform will be the penultimate trains to pass through the last passenger platform, calculates the destination information of all trains planned to pass through each platform, and updates the information on the platform PIS screen when the trains leave the station.

[0056] The ATS system calculates the destination information for both the platform and the train according to the planned timetable. If the timing for displaying the destination information has not yet arrived, the platform PIS screen and the onboard PIS screen will display the direction of "inner loop" or "outer loop".
