The invention relates to railway transport and can be used in automated systems Supervisory control of railway transport.

The known method and implements his system optimal traffic control in centralized traffic control, for which a safe speed and the interval between the passing of the following trains is automatically maintained locomotive onboard devices receiving initial information about the coordinates of its neighboring trains on the section control from the remote control centre for digital radio channel, as well as from on-Board satellite navigation device. When this train is equipped with control devices safe composition, and the range regulated by the coordinate method (journal of the Railway of the world", 2005, №4, p.46-52, "Promoting projects ETCS in Europe").

The disadvantage of this method and implementing it systems is the lack of control of kink rails, which limits their use.

The known method and implements his system optimal traffic control, including centralized traffic control, for which a safe speed and the interval between the passing of the following trains are automatically supported locomotive onboard device control is possible with Autolock (AB) with track circuits (Y.A. Kravtsov "Systems of railway automatics and telemechanics". - M., Transport, 1996, s.255, see figure 8.1, s, RES, 5.8, s, fig.5.10).

The disadvantage of this method and implementing it system is low-bandwidth and efficient trains, due to the lack of information about movement parameters in front of a train for the next train.

The closest to the invention by the combination of essential features is the interval regulation of traffic with centralized traffic control and the three-digit block with through traffic lights, which automatically maintain the locomotive on-Board control devices together with devices Autolock safe speed and spacing along the way, following the tracks the trains and the movement of each of the passing of the following trains under the green light of the first in the direction of travel of the train of light in the green light of the second direction of travel of the train traffic, with the locomotive on-Board device control each train and dispatch control center during the movement of each train to the first in its course of movement of the light with green fire and provided that at the second traffic light on its course of movement still burns yellow flames periodically receive data R is the counting time shifts referred yellow lights in green lights and use the information to optimize the management of the movement of each train individually and all trains on the control plot in General.

The system that implements the above method contains in the way of the three-digit device Autolock with track circuits connected to messaging devices EC stations, limiting driving and dispatching control center, which is across the trunk line connection connected to messaging devices EC, dispatch control center via radio digital communications connected with the on-Board control devices locomotives trains involved in Supervisory control, and on each of the locomotives on-Board control unit is connected with the on-Board satellite navigation receivers (EN 2387563, B61L 27/00, 27.04.10).

Forecasting the switching times of the signal reading lights facilitates the work of machinists and increases throughput.

To implement this technical solution the mobile unit rail transport, before moving trains with automatic driving devices must be equipped with modern kits onboard equipment control devices, digital communication and satellite navigation, for example, CLUB-U. today there are a significant number of mobile units of rail vehicles not equipped with such equipment. In addition, in actual use, possible partial and complete failure of the locomotive apparatus. The length of BC is K-plots at the three-digit block can vary in the range of 1-2 .5 km, and the length of trains mixed freight and passenger traffic can vary in a larger range of values. These circumstances limit the ability of the known technical solutions.

The technical result of the invention is to improve the efficiency of devices of the automatic driving trains on three lines AB with through traffic lights.

In terms of how the technical result is achieved by the fact that in the interval regulation of traffic with centralized traffic control and the three-digit block with through traffic lights, which automatically maintain the locomotive on-Board control devices together with devices Autolock safe speed and spacing along the way, following the tracks the trains, which operate under the green light of the first in the direction of travel of the train of light in the green light of the second direction of travel of the train traffic, locomotive onboard device control each train periodically calculate the predicted time of the release of the next block and transmit the data to the control center management, which is based on them computes the time change yellow light on green light at the second traffic light in the direction p is riding and transmits the calculation results to the onboard control unit of each of the locomotives, which optimise the maintenance process as each train individually, and all trains on the control site to the first, in his direction of travel, traffic light with green fire, provided that at the second traffic light, on his motion, still burns yellow flames, according to the invention dispatch control center calculates the distance to the end of the next part in front of the train as the summation of the increments of the coordinates and the equation S=V× T1, the speed of its movement to increment the coordinates of the distance traveled in one time interval between data samples based on the data of the electronic topographic map parcel of the way along the route and the formula: V=(L1+L2)/T, the data about the distance to the end of the next part in front of the train and the speed of its movement picks in descending order of accuracy for calculating the time shift yellow light on green light at the second traffic light in the direction of travel of the train,

where: L1 is the length of the previous block section;

L2 is the length of the train;

T - the duration of the busy state of the previous block section;

T1 - time traffic on the current block section.

At the technical result is achieved by the fact that the system for interval control trains with the way the three-digit device Autolock with track circuits connected to potowami the disabilities of the electrical interlocking stations, limiting driving and dispatching control center, in which a personal computer workstation via a trunk line connection connected to messaging devices electrical interlocking, and in a digital radio communication is connected with the on-Board control devices locomotives trains involved in Supervisory control, each of the locomotives on-Board control unit is connected with the onboard satellite navigation receiver, according to the invention in dispatching control center on the automated workplace module calculate and rank the data about distances between adjacent trains and the speed of their movement, the inputs of which are connected to the trunk line communication with messaging devices electrical interlocking input/output module calculation and ranking data is connected to the output/input of the processor of a personal computer workstation to the remote control centre.

The drawing shows a diagram of a system of interval control of trains that implements the proposed method.

System for interval control train movements contains the path of the device 1 three-digit lock with track circuits connected to the messaging device 2, when the second interlocking stations, limiting driving and dispatching control center 3, in which the personal computer 4 workstation through the line 5 a backbone connected to messaging devices 2 electrical interlocking and through channel 6 digital communication is connected with the on-Board devices 7 control 8 locomotives trains involved in Supervisory control, each of the locomotives 8 on-Board device 7 controls connected to the onboard receiver 9 satellite navigation, control center 3 management of the automated workplace module 10 calculate and rank the data about distances between adjacent trains and the speed of their movement, the input of which is connected to a line 5 backbone communications with messaging devices 2 electrical interlocking input/output module 10 calculation and ranking data is connected to the output/input of the processor of the personal computer 4 workstation control center 3 control.

System interval control train movements implements the proposed method is as follows.

During normal operation of the system when in front of the train passes the data about your location on the block and the current measured speed of its movement, a safe speed and spatial online is rwally passing between following trains are supported locomotive onboard devices 7 control with 1 Autolock with track circuits.

When the Autolock with through traffic lights outdoor lights are the primary means of regulation. Information is passed to the driver on the optical channel with the use of color and the combustion mode of the traffic lights. To improve traffic safety in accordance with the Rules of technical operation of Railways of the Russian Federation system Autolock complemented by ALS devices. On the way in the structure of the device 1 Autolock with track circuits placed travel device encoding ALS (not shown), and an onboard unit 7 control 8 locomotives are composed of locomotive device continuous ALS with hitch (not shown). They may have more complex on-Board control system, including, in particular, the automatic driving device (not shown).

Dispatch center 3 control communicates via digital radio communication 6 with onboard devices 7 control 8 locomotives, equipped with devices for the exchange of digital control information. On each of 8 locomotives, equipped with modern control systems, its on-Board device 7 controls continuously calculates the coordinates of the current location and speed of trains. Determination of coordinates is based on data obtained from airborne receivers 9 satellite Navi the purpose of adjustments from existing (not shown) in the on-Board device 7 control sensors of the distance and data from electronic topographic map plots the path along the route of the train. Based on the available in the on-Board device 7 controls the automatic driving program information about the length of the train, the length of the block along the route of the train and the speed of the train, the airborne unit 7 management periodically calculates the predicted time of the release of the next block and sends the data through the radio channel 6 digital communication to the control center 3 control, which on the basis of the received data passes through a digital radio channel 6 communication device 7 control locomotives 8 the calculated time shifts yellow light on green light at the second traffic light in the direction of travel of the train.

If ahead, the train does not transmit data about their speed, but periodically transmits measured by the onboard receiver 9 satellite navigation the X coordinate of the current location of the locomotive 8 trains, the module 10 calculate and rank the data about distances between adjacent trains and the speed of their movement counts less accurate assessment of the current distance to the end of the train ahead of the train and the average speed of its movement to the next path segment in the time interval between data samples.

The distance to the end of the next part in front of the train is determined by the module 10 by summing the increments x Current speed is determined by the increment to the ordinate distance traveled in one time interval between data samples based on the data of the electronic topographic map plots the path along the route of the train.

If ahead, the train does not transmit data about your location on the block, its composition and speed, the average speed is calculated by the formula:

V=(L1+L2)/T,

where:

L1 is the length of the previous block section;

L2 is the length of the train;

T - the duration of the busy state of the previous block.

The estimate of the distance S traveled by train from the release of the previous block for the current block-plot for time T1 of traffic on the current block-area is calculated by the formula:

S=V×T1

In both cases, the accuracy of the calculation increases with decreasing time intervals between receptions of the information from the previous train.

Then the module 10 calculate and rank the data about distances between adjacent trains and their movement speeds selects from the available received from the locomotive designed for the most accurate procedure data about distances between adjacent trains and the speed of their movement and transmits them to the control center 3 control, which on the basis of the obtained data transfers to the device 7 controls each of the locomotives 8 via digital radio 6 communication the results of the computation time shifts yellow light on green light at the second traffic light in the direction of travel of the train.

In all these cases, information about the distance to the end of the composition and speed go ahead is it trains allows devices automatic driving behind a moving train to develop an optimized strategy automatic driving trains given the current priorities of automatic driving. Such tasks can be:

maintaining a specified schedule, reduce energy costs, increase equipment longevity trains and track infrastructure, improving the fluidity of the movement for the comfort of passengers and cargo, and so on.
