Description

Technical Field

[0001] The present invention relates to the technical field of railway signal systems, and more particularly to a statistical analysis method for poorly divided sections based on a TDCS or CTC system. Background Art

[0002] At present, there are a large number of sections with poor track circuit shunts in the railway. Poor track shunts will cause the approach route to be unlocked prematurely due to the inability to complete the train occupancy inspection, causing the switch to be switched midway, resulting in accidents such as squeezed switches, derailment, and side collisions of trains. There are many reasons for poor track circuit shunts, and the rust and pollution of the rail surface are particularly prominent, resulting in "unable to crush to death" and "lost cars", posing safety hazards to railway transportation. The management of sections with poor track circuit shunts has the following problems: First, there are a large number of sections with poor track circuit shunts, which rely on manual statistics and reporting at all levels, resulting in a large amount of data and time-consuming and labor-intensive; second, the management of situations such as organizing the cancellation of sections by rolling or coating and plating, the registration of sections due to construction or weather reasons, and the recurrence of poor shunts in sections that have been cancelled is lagging, inefficient, and the statistical reports formed are not unified and accurate.

[0003] At present, the problem of poor track circuit branching cannot be fundamentally solved both at home and abroad. However, the management of sections with poor track circuit branching is particularly important, and there is a lack of research on dynamic control and automatic statistical analysis of sections with poor track circuit branching.

[0004] In existing patents and papers, there are relatively few tools for managing poor branch sections. Qi Chenghui's master's thesis, titled "Research and Development of Railway Track Circuit Poor Branch Control System", describes a system that simulates the on-site track circuit status, collects experimental data and completes branch poor control. In this scheme, it is difficult to collect branch poor data and there are inaccuracies. The final statistical results of branch poorness have certain errors.

[0005] At present, there is a lack of automated statistical analysis of poorly branched sections of track circuits. There is an urgent need for a method that can effectively solve the problems of low statistical efficiency and inaccurate statistical data in poorly branched sections, so as to solve the daily management of poorly branched sections. Summary of the invention

[0006] In order to overcome the defects existing in the above-mentioned prior art, the present invention discloses a statistical analysis method for poor shunt sections based on the TDCS or CTC system. The purpose of the present invention is to solve the problems of low statistical efficiency and inaccurate statistical data in the prior art for analyzing poor shunt sections of track circuits. The present invention is based on the TDCS or CTC system, obtains a registration and cancellation table, an equipment status change table and a rolling detail table, and then obtains the existing records, registration and cancellation records and rolling record information of all sections, which are used to solve the daily management of poor shunt sections. Through automatic statistical analysis and dynamic control of poor shunt sections, it can reasonably arrange and organize rolling, ensure driving safety and improve operational efficiency.

[0007] In order to achieve the above objectives, the technical solution adopted by the present invention is:

[0008] In the present invention, station-related personnel perform poor branching detection on sections manually or by equipment. After confirming that a section has poor branching, station-related personnel mark the section as poor branching on the TDCS or CTC system. During this process, the TDCS or CTC system will always record all equipment statuses in the equipment status file. The method obtains the status information of the section by parsing the equipment status file generated during the operation of the TDCS or CTC system. In particular, the status change of the poor branching of the section can be obtained. Combined with the station data file, the registration, cancellation and rolling records of the poor branching section can be parsed.

[0009] Definition 1: A segment can be divided into an unmarked state and a marked state according to whether there is a bad branch mark. If a segment does not have a bad branch mark, the segment state is recorded as Sa; if a segment has a bad branch mark, the segment state is recorded as Sb. A segment with a bad branch mark is called a bad branch segment.

[0010] The sections include the station's non-switch section, switch section and track section.

[0011] Definition 2: Register indicates that the status of the segment changes from the state Sa without the bad branch mark to the state Sb with the bad branch mark; cancel indicates that the status of the segment changes from the state Sb with the bad branch mark to the state Sa without the bad branch mark.

[0012] Definition 3: The scenarios of bad section registration, cancellation and rolling in railway transportation production operations are as follows:

[0013] 1) The segment is in the badly shunted and unmarked state Sa. At a certain moment, a segment is registered on the TDCS or CTC system.

[0014] 2) After registration, the bad branch mark status of the section will continue until it is cancelled. This period of time is recorded as the bad branch mark duration state Sc;

[0015] 3) When a section is in the process of continuous bad road division mark state, a vehicle passes through the section, causing the section to be run over once, and the section is recorded as being run over once;

[0016] 4) At a certain moment, the segment with the continuous state of bad branching mark is cancelled on the TDCS or CTC system, and the segment is restored from the bad branching marked state Sb to the bad branching unmarked state Sa, indicating the end of a scene.

[0017] In the present invention, the TDCS system refers to the railway train dispatching and command system; the CTC system refers to the railway dispatching and centralized system.

After confirming that a section has poor branching, the station personnel mark the section as poor branching on the TDCS or CTC system. During this process, the TDCS or CTC system will always record all equipment status in the equipment status file. This method obtains the status information of the section by parsing the equipment status file generated during the operation of the TDCS or CTC system.

The method for statistical analysis of bad branch sections according to claim 1, characterized in that: The S5 step comprises the following steps: S51, read the device status file; S52, parsing the equipment status information of the equipment status file, obtaining the occupation and clearance information of all routes, when the section occupied by the route is in a state of having a bad branching mark at the time of occupation, the bad branching section is recorded as being rolled once, and the rolling record of the bad branching section is saved in the rolling details table; S53, reading the device status files of subsequent times in chronological order.

9. The statistical analysis method of bad branching sections according to claim 8, characterized in that: In the step S5, the rolling details table is used to save the rolling records, and the rolling records are used to record the detailed information of the bad branch section of each rolling, including the rolling section name, the station to which it belongs, the rolling time and the rolling route name.

10. The method for statistical analysis of bad branching sections according to claim 1, characterized in that: In the step S6, statistics are collected on the poorly divided sections in multiple dimensions according to information including time, electric section, train section, line, location and track; In the step S6, the existing record is the section information with the continuous state of the bad branch mark, including the section name, the station to which it belongs, the section type, the bad branch position, the registration time and the registration residual pressure value.
