Description

The invention relates to the field of railway automation and is intended for use in train control systems.

The technology of transportation planning and management is largely determined by the quality of shift-daily planning in the form of a train schedule.

A device for controlling the movement of trains, providing traffic control on many sections of the railway track, with the implementation of automatic routing of trains and railway signaling using a centralized dispatch device, and control the passage of trains (application JP No. 200413161645, IPC: B61L 27/00, published December 11, 2001) - an analogue.

A disadvantage of the known solution is that this device is not intended to solve forecast problems and cannot be adapted for this.

A known system for controlling high-speed traffic on the railroad, in which a personal electronic computer installed on the workstation of the train dispatcher, is connected via an interface to the control panel of the train dispatcher, a second personal electronic computer installed on the workstation of the train dispatcher connected to a memory unit in which a motion execution schedule is recorded, and personal electronic computers We, which are installed at controlled points located along the high-speed traffic area, are connected via interfacing devices to centralized dispatching equipment, electric centralization and identification and monitoring tools for the train unit of the corresponding controlled point (patent RU No. 87986 U1, IPC: B61L 27/00 , published on October 27, 2009) - an analogue.

A known system for controlling the movement of moving units, containing many passive elements (transponders) to determine the position of the moving unit. The instantaneous position of the unit within the line network is determined by continuous measurement of the current distance. Data on sections of the track is stored in a central repository. The vehicle is controlled by transmitting from the central equipment to each mobile unit control data generated on the basis of information about the individual relative position of the closest other mobile unit to it (US patent No. 5740046, IPC: B61L 25/02, published on 04/14/1998 ) is an analogue.

In the known system, the predictions obtained can only apply to the closest moving unit. Thus, the system can carry out the formation and control of the execution of only current commands.

The same can be said about the control system for the movement of multiple freight trains through a multi-route railway system of increased efficiency and safety, described in US patent No. 5828979, IPC: B61L 27/00, publ. October 27, 1998) - an analogue.

Movements of the freight train are carefully monitored and organized in accordance with the dynamic schedule, the relative position of all trains, speed limits and the features of the track topography and train composition based on the response of the train during braking and power supply. To form train schedules, a train simulation tool can be used (patent RU No. 2207279, IPC: B61L 27/00, published on June 27, 2003) - an analogue.

A device is known for constructing optimal energy-saving train schedules, containing blocks for obtaining information about train passage, generating and presenting train schedules, correcting and monitoring the adequacy of the device, calculating a traction power supply system, a unit for generating an optimal traffic schedule and calculating the section throughput (patent RU 73100 U1 IPC: G06F 17/50, published on May 10, 2008) - analogue.

This device is designed for automatic, continuous in time management and analysis of the optimal schedule of trains of electrified railways. An optimal traffic schedule is understood to mean a traffic schedule that will meet the minimum operating costs, but at the same time, the electric power parameters of the power supply system will satisfy the requirements of the Rules for Technical Operation of Railways. The formation of the optimal schedule in this device is based on the calculation of the throughput of the railway section. This does not take into account data regarding the current situation on the site, in addition, a number of initial data cannot be automatically taken into account and must be entered manually. Essentially, this device does not automatically account for various categories of trains, which makes it impossible to automatically construct a train schedule simultaneously for all railway vehicles traveling on the site. In addition, although the possibility of analyzing an optimal movement schedule is mentioned in this document, this device essentially does not contain technical means for analyzing the execution of the schedule and automatically collecting statistical data on the implementation of the forecast schedule and the compliance of this schedule with the schedule of the executed movement.

The technical result, the achievement of which the claimed solution is directed, is to increase the accuracy of constructing a train schedule with automatic consideration of the current situation and conditions for the passage of trains, its analysis and obtaining data on the schedule.

The specified technical result is achieved by the fact that the device for constructing predictive energy-saving train schedules contains a unit for obtaining information about the current train position and conditions for admission, a unit for obtaining data on a standard train schedule, means for laying train threads, an energy-saving train schedule generating unit, one of whose inputs associated with the output of the manual data input unit, the train traction mode modeling unit when moving along a section of the track whose input is connected with the output of the information storage unit for the landfill through the information extraction unit for the landfill from the storage unit, the unit for receiving data about the planned “windows”, the unit for transmitting the forecast schedule to the train traffic control system, the block for obtaining the executed train schedule, the unit for comparing the forecast and executed schedules while the means of laying train threads include a block for laying threads of passenger and electric trains, the inputs associated with the output of the block for obtaining data of a standard traffic schedule, you the progress of the unit for obtaining information about the current train position and the output of the unit for modeling the traction modes of the train when it is moving along the track, and the output is with one of the inputs of the unit for decoupling passenger and electric trains, the second input is connected to the output of the unit for obtaining data on the conditions for the passage of trains, including data on the priority of train traffic, and the output of the passenger and electric train interchange unit is connected to one of the inputs of the freight train threading unit, the other inputs of which are connected to the unit output and obtaining the data of the normative schedule of movement, by the output of the unit for obtaining information about the current train position and the output of the unit for modeling the traction modes of the train when it moves along a section of the track, and the output of the block for laying thread of freight trains is connected to one of the inputs of the block for decoupling the threads of freight and passenger trains, the other the input of which is connected with the output of the data acquisition unit about the planned “windows”, and the output is connected with the other input of the energy-saving traffic schedule generation unit, the output of which is connected to the input of the storage unit a fire schedule, the output of which is connected to the input of the transmission block of the forecast schedule in the train traffic control system, one of the inputs of the information display and registration unit, the other input of which is connected to the output of the comparison unit of the forecast and executed schedules, one input of which is connected to the output of the storage unit of the forecast schedule , and the other input - with the output of the block receiving the executed schedule.

The device is characterized by the fact that to expand the functionality it contains a block for storing information on the landfill, including data on the profile and route plan, data on the stopping points - the coordinate, number, length and specialization of receiving and sending tracks, data on permissible and permitted train speeds on sections between stopping points, etc.

The technology of transportation planning and management is largely determined by the quality of shift-daily planning in the form of a train schedule. Currently, the dispatching apparatus on the railways provides full automation of information flows about the current state of the transportation process, the work of all involved services, the presentation of the scope of work and operating conditions. However, there is no clear automated mechanism for the intelligent planning of the transportation process (forecast schedule), taking into account the current situation and the planned permit conditions.

Currently, such planning is based on the personal experience of train, station and locomotive dispatchers.

Obviously, to increase the efficiency of the dispatching apparatus, it is necessary to create an automated system (device) for developing forecast train schedules, which would combine the functions of creating schedules taking into account the technology of the transportation process and its optimization according to a number of specified criteria.

The proposed device performs the following functions:

- building a predictive energy-saving train schedule for given sections of the railway training ground and time interval, for example, building a daily schedule;

- automatic transmission of the received forecast daily energy-saving schedule for execution, as well as for the staff of the existing vertical management of the train operation of the railway landfill;

- an automated assessment of the implementation of the predicted energy-saving train schedule, for example, daily, and the issuance of appropriate reporting forms.

The claimed solution is specified in figure 1, which shows the structural diagram of the proposed device.

There are also a block 14 for storing the forecast schedule, a block 15 for transmitting the forecast schedule to the train control system, a block (means) 16 for obtaining an executed schedule, a block (means) 17 for comparing the forecast and executed schedule, a block (means) 18 for displaying and recording information. Block 2 of the data of the standard schedule contains, for example, data of the arrival of the train at predetermined points.

Design features of the proposed solutions and its work are given below.

The output of block 7 is connected to the other input of the energy-saving schedule formation unit 8, the output of which is connected to the input of the forecast schedule storage unit 14, the output of which is connected to the input of the forecast schedule transmission unit 15 to the train traffic control system, by one of the inputs of the information display and registration block 18, the other input of block 18 is connected with the output of block 17 comparing the forecast and executed charts. One input of block 17 is connected to the output of the forecast storage block 14, and the other input is connected to the output of the executed schedule receiving block 16.

The normative schedules and variant schedules received by block 1 must be docked on the entire training ground. Therefore, the downloaded data is checked for consistency and the docking of all schedules into a single end-to-end schedule throughout the railway operating range.

A device for constructing predictive and train schedules comprises a unit 1 for obtaining information about the current train position, a unit 2 for obtaining data for a standard train schedule. Based on these data, the laying of passenger and electric train threads is carried out taking into account the categories of their admission and their decoupling. Next, the construction of the threads of freight trains and their interchange with passenger and electric trains are carried out. The results are displayed on the display and registration facilities, as well as in the motion control system and saved for automatic comparison with the executed schedule.

The device operates 24 hours a day.

All functions are implemented automatically. At the same time, it is possible to configure the device to work in a dialogue mode with the issuance of relevant information at the user's request.

In real-time mode, automatic loading of data on the current train position at the training ground and conditions of admission is carried out and the planned “windows” are loaded for the coming period, for example, a day.

Based on the data on the train position, on the conditions for the passage of local trains, train formation at the nodes and the forecast of train approaches to the section under consideration, a forecast train schedule should be constructed. When building a graph, you must consider the following source data:

- the topology of sections and directions of the railway (stations, haul lengths, number of tracks, haul profile, etc.), accepted weight standards;

- a self-locking system and the length of block sections, restrictions on the intervals of passing along imposed by power supply;

- the size and structure of train flows;

- shoulders of locomotive and locomotive crews;

- Schedules of passenger trains and the real schedule of passenger trains;

- freight train schedules and real freight train schedules, train approach with a depth sufficient for planning;

- train formation at nodes based on statistical data;

- the number and length of station tracks at local stations and their specialization;

- regulatory documents defining the technology of train work at the landfill, permanent and temporary restrictions on speed;

- data on the "windows" for repair and restoration work.

Enter data on train sections, train input flows, conditions of admission. At the same time, the train schedule, operational data, including the characteristics of the input train flows, the characteristics of each train and the conditions for admission, and auxiliary data, including data on the section in the form of a set of logically connected data arrays, including data arrays, are set , for example, stations or other sections of the track, and characterizing the number and length of tracks, specify the characteristics of each train as a composite distributed object in the form of an array of data, including data data on locomotives and wagons, they also enter data on speed limits according to the state of the track and the speed prescribed by the indications of traffic lights, and the track profile, etc.

The external commands created by the system and / or the user are received, moreover, if several commands are received, the decision is made in accordance with the priority of the command (block 3), which eliminates the competition of teams. User commands may have a higher priority on execution compared to commands created by the system. The data from the simulation processes are received in blocks 4-7, the simulation results are saved by block 14 and block 11, and the results are displayed by block 18. At the same time, it is possible to stop the simulation and return to an arbitrarily selected earlier cycle.

Recalculation of the forecast schedule should be carried out at the command of the operator or when a specified event occurs - the need to recalculate the forecast.

The forecast daily schedule should be transferred to the train control systems in automatic mode, where on its basis daily planning and implementation of train work of the freight railway direction will be carried out.

Information on the schedule of the executed movement is updated promptly with a delay, for example, no more than 3 minutes from the moment of the operation with the train. Information on the topology and regulatory documents that determine the organization of movement at the training ground is updated as it changes.

Information on the generated traffic schedule is uploaded at the request of the user of the system or automatically with a delay of no more than 3 minutes relative to the moment the task is set to issue information.

The inventive device has been tested with an automated assessment of the fulfillment of the predicted daily energy-saving schedule of trains and with the issuance of appropriate reporting forms for evaluating the performance of the daily energy-saving schedule of trains on the Isilkul-Chelyabinsk direction of the South Ural Railway in an operational mode.

Task input

An analysis of the fulfillment of the train schedule for the stations is carried out for two types of events: arrival and departure. For each event, the device determines the following parameters:

- total number of trains fixed at the station;

- the number of trains arriving / departing on schedule;

- percentage of trains arriving / departing on schedule;

- the number of late trains;

- percentage of late trains;

- the number of trains arriving / departing without a schedule;

- percentage of trains arriving / departing without a schedule.

To analyze the structure of the train flow, the number of trains is calculated by weight categories: 6000 tons, 7000 tons, 9000 tons. The number of double trains is also calculated.

An analysis of the train schedule in the direction is performed for given polygons (sections) according to the following parameters:

- the number of trains in the direction;

- the number of trains delivered during the period;

- train speeds;

- execution of the schedule;

- the number of hauls traveled with energy-optimal travel time;

- the number of trains that have 100% completed the energy optimal schedule;

- number of stops;

- duration of stops;

- number of train stops;

- duration of train stops.

Within a month, trains departed from stations on solid “lines” of the schedule. As a result of testing, the goals were achieved: adhering to the schedule discipline, accelerating the train flow, saving fuel and energy resources by reducing non-scheduled freight train stops and following them “to remove” the traffic light yellow (3%), reducing operating costs by transportation.
