Description

The invention relates to railway transport and can be used to control the transportation process.

A known method of dispatching congestion in a railway system containing a network of rail tracks and a plurality of trains provided by a schedule for movement on a network of rail tracks, comprising the following steps:

(a) determining the presence of congestion along the rail network and identifying the first train included in this congestion, (b) determining the area for reversing surrounding the congestion, (c) choosing a safe place outside the area of reversing for the second train that was previously planned to enter the reversing area, (D) plan the movement of the second train to a safe place, (e) identify alternative resources available to alleviate the congestion, and (D) plan the movement of the first train using identifiers alternative resources (RU 431581, B61L 27/00, 10.20.2011).

The disadvantage of this method is its low efficiency due to the significant investment of time required to redirect trains caught in a traffic jam, since there are not always free railway lines along which trains can be redirected.

The closest in technical essence is a system for planning train passes during the repair of a track section, which implements a method according to which various variant schedules are calculated for the period of repair of a railway track, form them into a data array, followed by their transfer and storage on the road server. The optimal variant schedule calculated by the system arrives at least three days in the traffic control center to familiarize the dispatching staff, who, when repairs are performed, are guided by the schedule for organizing traffic on the railway section (RU 86927, B61L. 27/04, 09.09. 2009).

The known system does not provide for the prompt transfer of the calculated variant schedule to trains in case of conflict (sudden breakdown of a locomotive, track malfunction, etc.) when it is necessary to ensure the movement of trains on a railway section taking into account the current situation. This system is intended only for calculating a variant train schedule providing train passes during the planned repair of a railway section.

The technical result of the invention is to create a spatio-temporal method of transition to a variant train schedule in case of violation of the standard schedule and increasing the throughput of railway lines.

The technical result is achieved by the fact that in the method of controlling the movement of trains using variant schedules, which consists in information interaction between the road server, the personal computer of the dispatcher’s workstation and the on-board equipment of train locomotives, in which, in case of violation of the normative schedule of train movements, through the first communication channel from the automated workplace of the dispatcher transmit a request to the on-board equipment of the locomotive of the train following with a delay, gave e information from the on-board equipment of the locomotive is transmitted to the dispatcher’s workstation about the reasons for the delay, according to the invention, the information received upon request is input into the computing unit of the dispatcher’s workstation, in which various variant traffic schedules are calculated, the calculation results are transmitted via the second communication channel to the road server to generate an array of data on the passage of trains, choose the optimal schedule for all trains located on the railway section, on which There was a delay in the rum, the selected optimal schedule is formed into a data packet, which is transmitted through the road server via the third communication channel to the on-board equipment of the train locomotives located on the railway section, after receiving information about the optimal variant schedule from the on-board equipment of each train locomotive through the road server to the automated the dispatcher’s workplace sends an acknowledgment of the receipt of an information package containing a variant schedule, after which the trains continue to move according to his schedule, while the boundaries of the railway section are fixed on the electronic map by the reference points that correspond to the coordinates of the output traffic lights, the tracking of the reference points by the trains is fixed by the train monitoring unit, which records and displays the recorded information on the monitor of the dispatcher's workstation for visual control in real time the time schedule for the traffic on the railway section of the dispatch control.

The method of controlling the movement of trains using variant schedules is as follows.

Blocks for monitoring the movement of trains of a separate railway section have been entered into the road server, the memory of which contains information about separate points, hauls, specialization and the number of trains accepted for work on the section, train schedules, data on inter-train and station intervals used for this section. Through the road server, information about the train's progress at stations and separate points is transmitted to the monitor of the dispatcher's automated workstation. In the monitoring unit of the infrastructure of the road server, separate points of the railway section are recorded, with their route development and infrastructure and information on the route development of all the railway sections. Interaction with signaling, centralization and blocking devices (STB) is carried out at the level of receiving signals from outdoor devices. At the same time, the centralized dispatching system (DC / DC / SPD) is used as a source of data on signaling signals. Based on the information from the signaling devices, messages are generated about operations with trains (train movement, parking, etc.) and transmitted via a communication channel to the ASOUP database located on the road server. Signals from signaling devices are used to automatically generate a schedule of executed train traffic.

The obtained data on the movement of trains and the operation of infrastructure facilities via communication channels are transmitted to the data receiving unit installed on the road server, through which all received information is transmitted via the communication channel to

dispatcher workstation from which the dispatcher provides operational control of train traffic on the railway section.

Based on the reference information stored in the database of the road server, the entire railway section formed in the geographic information system is plotted on an electronic map with the coordinates and broken by reference points. The reference points correspond to the coordinates of the output traffic lights of separate points. When the train follows the output signal, the dispatcher monitors the execution of the traffic schedule by comparing the time of the follow-up of the output traffic light set at a separate point with the time of the follow-up according to the standard schedule.

On the road server and on-board equipment of the locomotive, a mobile module is installed to determine the location of the train, consisting of a satellite signal receiver and a module for storing and transmitting coordinate data. The data transmission module allows the dispatcher to see the location of the train on the railway section. When following a train along a railway section, data is exchanged on the location of the train. The received data is analyzed and issued to the dispatcher in text form or using cartographic information. The mobile module is based on satellite signal receivers operating in the GPS and GLONASS standards. Also, on the road server and on-board equipment of locomotives, modules of an integrated communication system with data exchange between the locomotive and the dispatcher operating in the 08M-K + 160 MHz standards are installed.

At the dispatcher’s workstation, a conflict recognition and resolution unit is installed, the memory of which contains a list of conflicts (conflicts are qualified as: “slow train”, train delays, warnings on the stage, “window”, “window” on the way to a separate point), which or otherwise affect the implementation of the regulatory train schedule.

In the event of a conflict, the dispatcher, at his automated workstation through the communication channel, asks the driver for the reason for the delay or lag from the standard schedule, determines the trains that are affected by the current conflict, as well as the time of deviation from the current schedule of the first train (except for the train that provoked change of train schedule).

During the time Tr, all other trains, except those involved in the conflict and stopped by preliminary calculation, move according to the previously approved (normative) schedule.

After determining the causes of the conflict, its parameters are entered into the processor of the dispatcher's automated workstation, on which the conflict recognition and resolution unit is installed, connected by a communication channel to the variant schedule calculation unit, which calculates the variant train schedules.

After the calculation of variant schedules carried out by the automated system, the following information is displayed on the monitor of the dispatcher's automated workstation: those located on the train section with a possible deviation from the schedule; trains that will follow to the next separate point with a stop and calculated variant train schedules. Obtained by calculating the variant graphs is formed into a data packet.

After calculating the variant schedules, they are compared with the existing standard schedule, according to the results of which the optimal variant schedule of movement is selected. Then, through the channels of the communication system 08M-K- through the data transfer server to the modem 08M-K located in the locomotive cab and having a feedback channel with the dispatcher, a data packet is transmitted (a variant schedule calculated for this train, in which there will be information, over time Arrivals and departures to separate points along the entire route of the train).

Simultaneously with the transfer of the variant schedule to the conflict train to all trains, the movement of which was affected by the conflict, as a result of which there was a violation of the schedule, the on-board equipment of these trains will receive the variant schedule calculated for them.

Train drivers after receiving the schedule through the GSM-K communication channel transmit confirmation of the schedule. The train receives the schedule automatically, the trains can be in motion, moving according to the permissible indications of traffic signals, and while standing at a separate point, while trains that were not affected by the conflict will not be transferred, and such trains will continue to move according to their normative schedule of movement.

The transition of trains to a variant timetable is carried out at reference points, which correspond to the coordinates of the output traffic lights of separate points, until which trains will continue to move according to the standard schedule. The received variant schedule contains information: about the time of the train traveling by one or another separate point, the necessary parking at the separate point, which was not previously planned according to the schedule, the time of stopping at the separate point.

After calculating and selecting the optimal variant schedule, this schedule is taken as the main one and goes into the standard schedule. Monitoring the implementation of the transmitted train schedule is carried out by the train monitoring unit, which records the train following the reference points (exit traffic lights), checking them against the time in the standard schedule.

This method will allow, as soon as possible, to enter all trains on the railway section into the standard schedule, which is the fundamental long-term technological document that governs the organization of operational work at all levels and levels of management in the railway transport, ensures the coordinated departure, investigation and arrival of trains of all categories to separate points at safe intervals and with the least delays along the route, linking the turnover of locomotives, locomo ivnyh brigades, brigades conductors of passenger trains and direct wagons, circular routes and other special trains.

In this case, the total time required to eliminate the train delay is (table 1):

T = t ₁ + t ₂ + t ₃ + t ₄ + t ₅ + t ₆ + t ₇ + t ₈ , min

Where:

t ₁ - information about the delay, min;

t ₂ - time to determine the location of trains on the site, min:

t ₃ - calculation time of various variant graphs, min;

t ₄ — time for transferring variant schedules to the road server, min;

t ₅ - time to select the optimal variant schedule, min;

t ₆ - transmission time variant generated on board equipment train min;

t ₇ - time of transmission of confirmation by the train driver about the receipt of the variant schedule, min;

t ₈ - time of putting all trains on the railway section into the standard schedule, min.

The boundaries of the railway section are fixed on an electronic map in the on-board equipment of the train locomotive and the processor of the automated dispatcher system with reference points that correspond to the coordinates of the output traffic lights installed on the railway line. Before the train approaches the reference point, the on-board equipment of the locomotive of the train receives a packet of data on the transition of the train to a variant schedule, the driver transmits a confirmation of receipt of the schedule and then follows the schedule indicated in the received schedule, and when the reference point is followed, the dispatcher monitors the execution of the transferred variant schedule . Those trains that were not affected by the delay will not be given a schedule; such trains will continue to move according to their standard schedule.

The effectiveness of the method of controlling the movement of trains using variant schedules is to reduce the time spent on the exchange of official information between the driver and the dispatcher in case of conflict situations related to the schedule of trains, and increase the throughput on the railway section.
