The invention relates to railway transport and can be used in centralized management of railway transport.

Known centralized train control for low-density rail lines containing the Central computer, connected via satellite link with the onboard equipment of locomotives. Onboard equipment of each locomotive contains a computer, which performs calculation software speed. Computers connected to the blocks receivers, satellite navigation and communications, and in her memory the recorded electronic route map (EP 1705095, B61L 25/02, 27.09.06). The system has a limited scope due to the lack of reliable testing of track infrastructure. No track circuits can not control the kinks and the removal of the rails, and the absence of surveillance systems does not allow to detect foreign objects and damage path.

A known system for controlling the movement of trains on station, in which the locomotives involved in the control system, installed on-Board computer, connected to the first port with the display, and the second port via on-Board unit is connected to the onboard antenna unit digital radio communication, the third port of the computer through the power receiver satellite navigation the th system connected to the receiving antenna of the satellite communications system, in memory of the onboard computer recorded digital map of the station and at the station housed the control and adjustment of the satellite communication station, in memory of which also recorded an electronic map of the station and the signals which is determined by the position of the boundaries of the protection zones, protecting rolling stock from the collision at station (EN 2288856, B61L 23/34, 10.12.06).

Closest to the claimed technical solution according to its technical essence is selected as a prototype system for train traffic control, containing a Central control and distributed control points on each item posted by the computer workstation operator control the movement of trains to ports which are connected to the first port unit equipment post, electrical interlocking, block devices, remote control and remote signaling and stationary device, radio communication with the locomotive, each paragraph ports block devices remote control and remote signaling connected with communication channels, and a stationary device, radio communication with the locomotive through a radio channel connected to the onboard transceiver devices that are installed on the engines, which are in the area of the corresponding stationary radio communication devices, with each locomotive to ports onboard the VM is connected on-Board transceiver device, the display unit train control and satellite navigation system receiver (Y.A. Kravtsov "Systems of railway automatics and telemechanics". M, Transport, 1996, s.293-294).

The disadvantage of the system should include limitations on the length of the plot centralized management due to the significant costs when implementing the communication line (wired or wireless) to the remote line items. The system also has excessive consumption of resources, equipment and electricity consumption at a low intensity movement of trains through controlled points.

The technical result of the invention is to reduce operating costs and increase the reliability and durability of equipment posts electric centralization, while maintaining its security, as well as in reducing the capital cost when connecting to the remote system and linear low-density points, not connected to a Central control point secure communication channels.

The technical result is achieved by the fact that the system for train traffic control, containing a Central control and distributed control points on each item posted by the computer workstation operator control the movement of trains to ports which are connected to the first port unit of equipment on the same electrical interlocking block devices remote control and remote signaling and stationary device, radio communication with the locomotive, each paragraph ports block devices remote control and remote signaling connected with communication channels, and a stationary device, radio communication with the locomotive through a radio channel connected to the onboard transceiver devices that are installed on the locomotives in the zone of the respective stationary radio communication devices, with each locomotive to ports onboard computer connected on-Board transceiver device, the display, the power train control and satellite navigation system receiver, according to the invention on each low-density distributed a controlled item is entered, the control unit standby mode of operation and the switching unit, the block devices remote control and remote signaling is connected to the control unit standby mode of operation, through which the switching unit is connected with the second port unit equipment post, electrical interlocking.

The drawing shows a diagram of the proposed system for train traffic control.

System for train traffic control provides a Central point 1 control and distributed control points 2, for each point (1, 2) posted by computer 3 automated raboteg the designated operator of train control, to ports which are connected to the first port block 4 equipment post, electrical interlocking, block 5 device remote control and remote signaling and stationary device 6 radio communication with the locomotive at each point (1, 2) ports block devices remote control and remote signaling connected with 7 channels of communication, and a stationary device 6 radio communication with the locomotive through a radio channel connected to the onboard transceiver devices 10 installed on locomotives 9 in the zone of the respective stationary devices 6 radio, with each locomotive 9 to ports on-Board computer 8 is connected on-Board transceiver device 10, a display 11, block 12 control the movement of the train and the receiver 13 satellite navigation system, on each low-density distributed a controlled item 2 introduced unit 14 controls standby mode of operation and the unit 15 switches, the block 5 device remote control and remote signaling is connected to the control unit 14 standby mode of operation, which through the unit 15 switches connected to the second port unit 4 equipment post, electrical interlocking. In the diagram distributed controlled items-intensive activities are not shown (scheme their construction is similar to the outline of the Central paragraph 1, of the control.

System for the management traffic is as follows.

When the movement of the locomotive along the Central paragraph 1 and distributed paragraphs 2 installation and removal of routes, the opening and closing of traffic lights and other actions on the passage of trains provides the operator of the Central paragraph 1 (train dispatcher (center)). At the same time he carries out the management process through its computer 3 automated workplace (AWP-center). To change States outdoor facilities electrical interlocking (EI) with arm-center sends coded signals telecommand (TC), and to record and display the train situation and the current state of outdoor objects EI, arm-center come from controlled points 2 code messages remote signaling (TC).

The exchange of information and THE TC between the computer 3 and blocks 4 equipment posts electrical interlocking geographically close to the Central point 1 control occurs via a secure communication channel 7, which allows the transmission and reception of responsible data requirements to ensure safety of trains. Open channels 7 can be used in the absence of communication over secure channels 7 and only to transmit information TC is not responsible for traffic safety. For telecontrol remote from the Central point 1 distributed controlled by 2 points in the system provided by the increase in the area radiowa and closed channels due to relay information via on-Board transceiver device 10 locomotives.

Existing special communication channels, such as channels for the transmission of voice information and data from networks of mobile-satellite communication "Globalstar and Inmarsat" provide the necessary level of accuracy of the information and are able to meet the requirements for the safe movement of trains. Another possibility is the use of GSM-R, in which the locomotive radio data transmission uses ranges 2 and 160 MHz and 900 MHz for telephone and data communication with the Central point 1 control. Locomotive satellite communication device together with the radionavigation-satellite terminals GLONASS/GPS provides positioning locomotives. To meet the requirements of the Railways on the transfer of responsible data for train control systems implement such functions as, for example, functional addressing, presentation of functional numbers, addressing depending on the current location and call processing with high priority.

Station device for regulating the movement of trains and power stations and tracks, which are characterized by periods of low intensity movement with unit 14 controls standby mode, which is controlled locomotive trains arriving or departing from the tanzie. Standby mode introduces a limited function devices (to reduce energy costs and other operational resources) while maintaining a sufficient level of readiness to resume operation in the normal mode. Unit 14 controls standby mode is set at each station area with probable minor traffic through the switching unit 15 includes the selected equipment EC in the operating or standby mode. When the unit 14 controls standby mode has no connection with the Central point 1 via a secure communication channels, it is only used for collecting and analyzing diagnostic information and referral through open communication channels to the Central control station 1 information about the serviceability or malfunction of devices EC. In the Central paragraph 1, control goes to the minimum necessary information that can be transmitted over the available on the station's public communication channels. For example, it may be the only information about the damages that need to be addressed before the arrival of the train. This information may be transmitted, for example, via a telephone line or through the phone in the normal cellular.

Circuit features blocks 14 control standby mode and the unit 15 switches are determined by the structure of the station devices, for which the task of saving the Republic is row. For example, to save power and resource of some impulse relay circuits for the signal from the unit 14 controls standby mode unit 15 switches track circuit switches to standby mode by detaching feeds them all from the working circuit. And the block 14 control standby mode alternately switches the supply ends off track circuits to its internal source (not shown) of the test signal, whereby (for example, according to statistics measure current consumption) it monitors the integrity of rail lines of station tracks. The measured parameters are compared with the statistically expected normative values stored in the memory unit 14 of the control standby mode for each track circuit. If the deviation exceeds the allowable limit, immediately conducted a series of repeated measurements for reliable determination of a malfunction of the track. For external monitoring of track infrastructure unit 14 controls standby mode through the unit 15 switches can perform periodic inclusion of cameras (not shown). Regular sending video images to a Central point 1 control requires stations of DECT systems and/or systems broadband radio access Wi-Fi, Wi-Max.

Timely detection surface is of Erdeni rails and other elements of the path allows you to make the necessary repairs with minimal impact on train schedules. Similarly, to conserve energy may change the terms of lighting and heating of the EC post and other objects of the station.

The frequency of inspections blocks 4 instruments EC posts is selected from the conditions for achieving the maximum economy of resources, while ensuring a given availability of devices and is a parameter that can be adjusted when changing driving conditions. For example, if the backup battery on the station upon interruption of the main power supply has spent the major part of the accumulated charge, the frequency of inspections can be reduced in addition to completely lose control of the station. The operation mode of the blocks 14 control standby mode on geographically remote from the Central point 1 control of distributed controlled items 2 change commands from the Central point 1 control while trains on station, and may take into account the forecast of operating conditions of the apparatus of this post to EC for a period of time until arrival of the next train. According to the received command can be set as the volume and frequency of checks. For example, with increasing traffic intensity (seasonal or due to maintenance and construction work) standby mode may provide an increase in the frequency of inspections and the depth counter is La and it may even be temporarily cancelled and by reducing the intensity of the motion and the relief, for example, temperature conditions, the frequency and depth control can be significantly reduced.

In the operating mode blocks 4 instruments EC posts due to the communication through the mobile radio communication with the locomotive on the PC monitor 3 Central point 1 continuously displays the current status of the corresponding station - the position of arrows, route, indications, signals and employment pathways. The operator of the Central paragraph 1 may transmit commands to the set route, the hands while performing shunting movements, etc. from your workplace, then these commands are passed through a secure system control and communication for execution of commands at the station. Along with the teams responsible for managing blocks of 4 instruments EC posts, which are produced in the Central paragraph 1, some responsible commands can also be produced by block 8 on-Board computer of the locomotive associated with the stationary device 6 of this radio station.

Protocols and encoding of messages for transmission via a secure communication channel 7 and the mobile radio communication with the locomotive selected based on the desired level of security. Codes for error detection and acknowledgement messages are integrated into the transmission system.

Job modes, the work units 14 control standby mode on geographically close from the center of the low-density distributed controlled items 2 through blocks 5 device remote control and remote signaling, associated with secure communication channels 7.

Thus, the proposed system provides lower operating costs and increases the reliability and durability of equipment EC posts without compromising its security. It also provides a reduction in capital costs when connecting to the remote system and linear low-density points, not connected to a Central control point secure communication channels 7.
