Description

The invention relates to rail transport and can be used in centralized control systems and ensuring the safety of train traffic both on high-speed rail transport and on public railway sections with heavy train traffic.

Known system ITARUS-ATC for controlling the movement of trains on railway transport, containing stationary and on-board equipment (A.S. Adadurov, P.A. Popov, Art. General principles of operation of the ITARUS-ATC system, J. Automation, communications, informatics, No. 7, 2010). The stationary equipment of the well-known system includes a radio block center, a redundant power supply system, a communication system, gateway equipment for linking with electrical interlocking and automatic blocking systems of stations. At the same time, the radio blocking center is connected to the main and backup switching centers via E1 ISDN PRI channels. To obtain information about the state of track circuits, route switches and indication of traffic lights, the radio block center interacts with the EC-EM systems. The radio block center receives information about the train number from the onboard equipment of trains via a digital radio channel; its location, speed and length. The received information is used in the radio block center to control the movement of trains by forming a movement permit individually for each train.

The onboard equipment of the ITARUS-ATC system is based on a KLUB-U or BLOK security device with modified software and a BIL-M display unit, a two-channel GSM-R radio station, a specialized gateway that implements the Euroradio protocol and provides interaction with the radio block center.

A known traffic control system for a high-speed highway, including a radio block center located at the central post of dispatch centralization, the control computer complex of which interacts with the control computer complex of the central dispatch centralization post, microprocessor centralization, the inputs / outputs of which are connected to the outputs / inputs of the hardware and software device of the automated workstation the station attendant and the control computer complex of the central dispatch center, floor devices, the control computer complex of the radio block center and the hardware and software device of the train interval control system with ALSEN and tonal track circuits, the GSM-R data transmission radio network and the on-board safety device installed on trains with a digital electronic map, made with the ability to interact with a satellite navigation system, tonal rail with new circuits and via a GSM-R data transmission radio network with a control computer complex of the corresponding radio block center, other inputs / outputs of which interact with an automated system of temporary speed limits (Baluev N.N., Problem solving options when creating a modern traffic control system, f. Automation, communication, informatics, 2017, No. 11, p.17-20).

The known system allows, with relatively low investment costs, to significantly reduce the passing interval of trains of different categories, to make this interval flexible and thereby significantly increase the line capacity.

However, in the known technical solutions, there is no automated monitoring of the state of infrastructure objects, namely, the contact network, track, artificial structures, etc., natural and climatic conditions that significantly affect traffic safety, especially high-speed trains.

In addition, the train restriction data comes from a system for issuing and canceling warnings that does not meet safety requirements. In the known system, there is no automated control over the execution of the train schedule using data received from on-board train safety devices, the variant train schedule is not calculated automatically in the event of conflict situations based on data from on-board train safety devices and data from diagnostic and monitoring systems.

In the known system, the exchange of data between radio block centers located in the transportation control center and microprocessor interlocking systems with interval train control systems located at the station and at the railway tracks occurs via an operational-technological communication network, which creates additional risks of security breaches and information protection.

The technical result of the invention is to expand the functionality, increase information content, protect against unauthorized exposure by centralizing the process of train traffic control at a dedicated training ground, reducing the number of operational personnel to control train traffic, and reducing the influence of the human factor.

In the proposed system, the organization of train traffic on the HSR is implemented from the road traffic control center.

Centralized transportation control is carried out by the automated dispatch control subsystem.

To implement the traffic control and safety functions, microprocessor control subsystems located at stations, technical diagnostics and monitoring, as well as train safety subsystems are used.

Each microprocessor control subsystem at the station provides automated control of non-stop train passage through the station with delimitation of the main and side track zones;

control of train operations from the traffic control center, including remote objects (control ramps);

autonomous control of traffic lights, turnouts, tonal track circuits at the station and adjacent spans directly from the station with AWP 23 DSP;

separate control of traffic lights, switches, tonal track circuits at the station and adjacent stretches.

Control from the road traffic control center is carried out from the hardware and software devices AWP 7 DGP and AWP 8-10 DNTs by the chief traffic dispatcher and train dispatchers. All the information required to control the movement of trains is displayed on the monitors AWP 7 DGP and AWP 8-10 DNTs and at TP 2.

All information on AWP 7 DGP and AWP 8-10 DNTs and TP 2 comes from CPU 1 in the form of diagrams of dispatching areas, stations, with indication of stationary objects and mobile objects (trains), as well as other information requested by the operational dispatch personnel.

CPU 1 forms a unified database of operational and archival information about monitored and controlled objects of the railway landfill, their condition and location relative to the coordinates of a single electronic landfill map (ECP), which is an integral part of the database.

Information on CPU 1 comes from

CPU 13 microprocessor control systems;

train safety subsystems;

TsSD 24 data servers of the subsystem of technical diagnostics and monitoring; an automated system for operational management of transportation (ASOUP); an automated system for issuing and canceling warnings (ACS VOP); module for generating a common time for synchronizing the operation of subsystems and functional blocks. In addition, CPU 1 corrects the database in real time based on the results of interaction with AWP 7 of the DGP; AWP 8, 9 and 10 DNTs; AUM 3; with functional blocks - OS 4, IGDP 6; VGDP 5, as well as with an automated system for maintaining and analyzing the schedule of the executed movement (GUID Ural).

The main train dispatcher with AWP 7 DGP provides general control over the implementation of train schedules at the range, manages the modes of movement of high-speed trains, starts the calculation and the introduction or cancellation of a variant train schedule at the range; if necessary, control of train operation at the selected dispatching area.

Information on the fulfillment of the train schedule at the test site at AWP 7 of the DGP comes from the central control center

- 5 036029 from the DGDP 6.

Movement control - starting, calculation, introduction and cancellation of a variant train schedule is performed by the chief traffic dispatcher by entering the appropriate commands from AWP 7

DGP for functional blocks AUM 3 and VGDP 5.

If the conditions for non-stop passage of trains from AWP 7 of the DGP are met, the chief traffic dispatcher enters a high-speed traffic command for transmission to AUM 3.

Upon receipt of a high-speed traffic command from AWP 7, the AUM 3 functional block requests information on the state and location of all objects in CPU 1, which is necessary for the introduction of an automated mode of non-stop passing trains along the main tracks of the polygon (high-speed traffic mode) both in one direction and in friend, analyzes it.

If the conditions for the possibility of non-stop passage of trains along the main tracks of the AUM 4 polygon match, it sends a high-speed command to AWPs 8, 9 and 10 of the DNTs and CPU 1, which, via SPD 12 OTN, transmits it to CPU 13 of all microprocessor control subsystems.

The functional block VGDP 5 in real time monitors the train situation at the landfill, conducts an automated analysis of conflict situations, on the basis of which it calculates a variant train schedule and sends it to AMP 7 of the DGP.

Upon receipt of information about the occurrence of conflict situations in the train schedule and variant schedules, the main traffic dispatcher, to optimize traffic with AWP 7 of the DGP, enters a command to resolve the variant schedule and transmits it to the VGDP 5. Upon receipt of permission, the VGDP 5 variant schedule transmits to the CP 1, which, through SPD 12 OTN sends data on the variant schedule to the switch of the digital radio communication network for subsequent transmission over the radio channel to the safety subsystem of the corresponding train.

After eliminating conflicts, similarly to AWP 7 of the DGP, the command to cancel the variant schedule is entered, while the CPU1 automatically sends information messages about the indicators of the standard schedule to the train safety subsystems.

With AWP 7, DGP can control train operation at each of the selected dispatching areas by introducing a request for transfer to control command and transferring it to AWP 8 or 9 or 10 DSC, followed by confirmation of the request by the train dispatcher.

The chief traffic dispatcher and train dispatchers through AWP 7 DGP and AWP 8, 9, 10 DSC carry out information exchange of data on the train situation.

Train dispatchers carry out control and management of train work in dedicated dispatch areas, including remote dispatch ramps;

transfer to separate management of facilities and control of train traffic along the main tracks of stations;

transfer of stations to autonomous control from AWP 23 EAF;

input of operational data on the speed limit of trains.

The objects of control and management of microprocessor control subsystems are arrows, traffic lights, tone track circuits, as well as switches heating devices. The monitor AWP 8, 9, 10 DNTs, including, displays information about the state of infrastructure facilities, data on meteorological conditions at stations and ranges and on the location of trains in dedicated control areas, information about which comes from the subsystems of technical diagnostics and monitoring and safety trains respectively.

Separate control of objects: transfer of switches, assignment of routes with opening traffic lights and cancellation of routes along the main tracks of the station, transfer to autonomous control of the microprocessor control subsystem at the station, change of the direction of movement along the tracks of the railway tracks are carried out by microprocessor control subsystems on the commands of train dispatchers in the absence of a high-speed traffic mode.

Separate control of objects is carried out by a team formed by train dispatchers with AWPs 8, 9 and 10 of the DNTs for the functional blocks MPTs 15 and IRDP 16 of the microprocessor control subsystems of the corresponding dispatching circle.

With the transfer to autonomous control, the control of objects is not interrupted.

In addition, train dispatchers with AWPs 8, 9 and 10 of the DNTs perform the input of operational data on limiting the speed of trains, received by telephone, or on stopping one or a group of trains, information about which is sent to OS 4.

CPU 1 in real time sends to OS 4 unit all data on train speed limits received from microprocessor control subsystems directly from AOS 17 units when diagnosing critical states of infrastructure facilities and unfavorable climatic conditions, from TsSD 24 subsystems for diagnostics and monitoring on the results of processing data from diagnostics of infrastructure facilities by automated mobile measuring complexes, from subsystems for ensuring the safety of trains on the fulfillment of speed limits, as well as from an automated control system based on the results of a field survey of infrastructure facilities by teams of service personnel.

In addition, train dispatchers with AWPs 8, 9, 10 of the DNTs send to the OS block 4 data on the speed limit of trains received by telephone in case of emergency situations at the range.

After processing the data, OS 4 sends a corresponding message to the CPU 1 and to the AWS 8 or 9 or 10 DNTs. CPU 1 generates a command to limit the speed or cancellation of restrictions and by SPD 12 OTN sends it to the CPU 13 of the corresponding subsystem of microprocessor control for transmission to the AOC unit 17.

Block IG DP 6 carries out automated data processing for the correspondence of the time and location of trains, taking into account the coordinates of their location on the electronic map of the polygon and forms a schedule of the executed train movement at the polygon.

The information on the schedule of the executed movement is transmitted by the DGDP 6 to the CPU 1, which, for each dispatching section, sends to the AWS 8, 9 and 10 of the DNTs information on the execution of the train schedule. Information on the fulfillment of the train schedule on the section is displayed on the monitor of the hardware-software device AWP 8, 9 and 10 of the DNTs. This allows the train dispatcher to monitor the train situation in his control area in real time.

Train dispatchers of different dispatching circles from their automated workstation through CPU 1 carry out a constant information exchange of data to provide real-time control of train traffic with the transfer of trains along the boundaries of the dispatch circles.

All operational information is recorded and archived in the memory of the CPU 1 of the automated dispatch control subsystem.

In case of temporary inoperability of one of the functional blocks, the data on the train situation is replenished and restored based on the stored data, respectively, by the CPU 13 of the microprocessor control subsystems and the controllers 33 of the train safety subsystems.

Microprocessor control subsystems located at the stations are included in a single microprocessor control data transmission network on the stretch.

Control commands CPU 1 transmits by means of SPD 12 OTN to CPU 13, which sends them to the functional blocks MPC 15, IRDP 16 and AOC 17.

To execute control commands, MPTs 15 monitors station tone track circuits through the UTRTs / ALS 21 and UTRTSASL / EN 22 object blocks, coding them with automatic locomotive signaling signals with standard and extended values (ALS / ALS-EN);

control and separate transfer of arrows through the USTR 20 object block;

assigning routes with automatic setting of arrows along the route, opening traffic lights through the IVDS 19 object block and canceling routes;

control and management of remote objects through object blocks of remote control (OUU);

changing the direction of movement along the tracks of the tracks together with IDRP 16;

transition to automatic control of tonal track circuits of the main tracks of IDRP 16 for the organization of non-stop admission when receiving a command for high-speed movement, as well as return to the original control;

control and management of switches, traffic lights, track circuits and routes, including shunting routes, on side tracks upon receipt of a command; high-speed movement with a fence for rolling stock to enter the main tracks;

control of secondary technical means, including heating of turnouts (not indicated on the drawing);

transmission of data on the state of monitored and controlled objects to RBC 18 and CPU 13.

Upon receipt of the command from the CPU 1 of the automated dispatch control subsystem, the autonomous control of the CPU 13 sends it to the MPTs 15 and AWP 23 of the EAF. In this case, the station attendant takes over the control function at the station.

IDRP 16, having received the appropriate commands from the CPU 13, monitors the track circuits;

setting the direction of movement together with MPC 15 on both tracks of controlled runs;

control of the progress of the train along the sections of the railway tracks in the given direction of movement;

coding of tonal track circuits with ALS signals (ALS-EN) in a given direction of movement, depending on the employment and freedom from rolling stock of track circuits;

coding of track circuits with ALS signals (ALS-EN) in a given direction of movement, depending on the state of infrastructure facilities and natural and climatic conditions, taking into account the need to reduce the speed of the train in case of receiving data on critical deviations in the operability of infrastructure facilities and in natural and climatic conditions from blocks DMI 30 and DPK 31, respectively;

- 7 036029 interval regulation of train traffic on the tracks with non-stop pass through the stations upon receipt of a high-speed traffic command from the automated dispatch control subsystem;

transfer of data on controlled and managed objects to RBC18;

transfer of data on controlled and managed objects to CPU 13 for subsequent transmission via SPD 12 OTN to CPU 1 of the automated dispatch control subsystem.

The AOS 17 functional block analyzes data on the state of infrastructure structures (tracks, artificial structures, contact networks, etc.) received from the DMI 30 unit, and data on the natural and climatic conditions in the service area (the state of karst voids, the presence of side wind, precipitation, ice formation, flooding of tracks, earthquakes, etc.) received from the MPK 31 block.

Taking into account the obtained data and the train situation, the AOC 17 unit generates the values of the permissible train speed in places of restriction based on the library of speed levels by the parameters of deviations stored in its memory. The level library is formed on the basis of the content standards approved by the infrastructure owner.

AOC 17 transmits data on the values of permissible speeds to RBC 18, IRDP16 and TsP13.

Based on the data received, the RBC 18 generates the corresponding information messages and, through the SPD 12 OTN, sends them to the input of the switch of the digital radio communication network for subsequent address transmission over the radio channel to the security subsystem of the corresponding train, and the IRDP 16 generates the corresponding signal codes and transmits them to the rail channel to the subsystem ensuring the safety of the corresponding train.

The CPU 13 sends data on the values of permissible speeds to the CPU 1 via SPD 12 OTN to control the execution of commands to limit the speed by the train.

RBC 18, based on the results of interaction with the train safety subsystems located in the control zone of the microprocessor control subsystem, collects information about the train situation from safety devices.

In addition, MPTs 15 and IDRP 16 transmit to RBC 18 data on the state of control and management objects in the area of their control and management, and data on speed limits are sent to RBC 18 from AOS 17 and through CPU 13 from the automated dispatch control subsystem.

RBC 18 processes the received data and generates information messages (commands) about the permission of movement or the prohibition of movement with the parameters necessary for the implementation of safe train guidance along the section in the control and management zone of the microprocessor control subsystem.

After that, RBC 18 establishes communication with the safety subsystems of trains located in the zone of its control, and exchanges data with them through the switching center via the radio channel of the digital radio communication network.

In addition, RBC 18 automatically establishes communication via LPMPSU with RBC 18 microprocessor control subsystems of neighboring stations and transmits information about trains approaching the boundaries of their control zones.

As a result of processing data on the execution of commands for movement by subsystems for ensuring the safety of trains and data on the location of trains, RBC 18 verifies the location data of trains with the data of the electronic card EK 14.

The data on the movement of trains on the section in the control zone of the microprocessor control subsystem RBC 18 sends to the CPU 13 for subsequent transmission through the SPD 12 OTN to the CPU 1 of the automated dispatch control subsystem.

In this case, the CPU 13 of each microprocessor control subsystem not only exchanges information with the CPU 1 of the automated dispatch control subsystem, but registers and stores information about all the processes and states of the objects under the control of the microprocessor control subsystem.

The CPU 13 has a secure gateway for connecting and transmitting data to the station data concentrator 26 of the technical diagnostics and monitoring subsystem (SD TDM), as well as for diagnosing the functional blocks of the microprocessor control subsystem from the hardware and software device of the mobile workstation of the duty electrician.

The subsystem of technical diagnostics and monitoring controls the technical parameters of objects according to two main criteria with the identification of pre-failure states of traffic lights, arrows, tonal track circuits;

critical deviations from the norms of the maintenance of the track, artificial structures (bridges, tunnels, etc.) (ISSO) and the contact network (CS), as well as the factors of natural and climatic conditions affecting the train process;

the state of the functional blocks of the subsystems of the automated dispatch control and microprocessor control.

ICE units 27, DSTR 28, DSTR 29 monitor and diagnose the state of traffic lights, switches and tonal track circuits, respectively, and transmit information about their state to

- 8 036029 station hub 26.

Block DMI 30 processes the data of technical means for diagnostics of the track (SDMP), contact network (SDMKS), artificial structures (SDISSO), and block DPK 31 - means for monitoring natural and meteorological conditions (SPK 1, 2, n ...). The results of the diagnostics of the DMI 30 and DPK 31 are sent to the station concentrator 26.

If critical deviations from the standards for the maintenance of controlled objects and natural and climatic factors affecting the movement of trains are detected, information about them by DMI 30 and DPK 31 is sent by means of the LS MPSU to the AOS 17 functional block of the microprocessor control subsystem at the station.

The data of the results of diagnostics and monitoring is sent by the station concentrator 26 to the CPU 13, and through the SPD 12 OTN - to the central server 24 of the technical diagnostics and monitoring subsystem.

Diagnostics of the functional blocks of the subsystem of automated dispatch control is performed by the subsystem of technical diagnostics and control by means of the hardware and software device of the automated workstation 25 of the duty electrician connected through the SD 24 to the CPU 1.

In addition, the technical diagnostics subsystem is equipped with a mobile automated workstation for an electrician on duty, the hardware and software device of which, through a secure gateway, can be connected to the corresponding input of the CPU 13 of each microprocessor control subsystem to conduct technical diagnostics of its functional object blocks.

The central data server 24 of the diagnostics and monitoring subsystem receives information from all station hubs 26, which makes it possible to form a complete database on the state of infrastructure facilities throughout the landfill.

In addition, the central server 26 also receives data on the state of infrastructure objects from a mobile complex for technical diagnostics and monitoring (not shown in the drawing).

At the same time, on the monitors of hardware and software devices AWP 25 operators of the subsystem of technical diagnostics and monitoring, information about the state of infrastructure objects is displayed. Operators in real time carry out data processing and analysis of pre-failure states of technical means and deviations in parameters from the standards for maintaining infrastructure facilities in order to plan maintenance of infrastructure facilities as per condition.

The digital radio communication network is a certified system to ensure reliable communication between RBC 18 microprocessor control subsystems and train safety subsystems at speeds up to 400 km / h.

The base stations of the digital data transmission network provide a reliable radio channel, taking into account the zone of reliable data transmission when the train passes between them. Each train is provided with a reliable radio channel due to the coverage area of two adjacent base stations.

To synchronize the operation of all functional subsystems of the control system and ensure the safety of train traffic on the stretch of their functional and object blocks, SPD 12 OTN and SPD 11 OBTN receive exact time signals from a universal time generator (not shown in the drawing).

The operation of the security subsystem is based on the tested algorithms of the well-known on-board security systems CLUB-U, BLOK, based on the use of automatic locomotive signaling of extended significance (ALS / EN) for interaction with track circuits, on the use of an electronic map of the site, including data on the location of infrastructure facilities, and satellite navigation for making corrections when determining the position of rolling stock on a railway section.

When the train moves in the control zone of the microprocessor control subsystem, the radio communication module 32 through the digital radio communication network provides information exchange with the BRBC 42 RBC 18 of the microprocessor control subsystem and with the CPU 1 of the automated dispatch control subsystem.

Module 38 satellite navigation in real time determines the geographical coordinates of the train and sends information about them to the controller 33.

The controller 33 also receives information from the sensor 35 of the distance traveled - the odometer. Taking into account the readings of the sensor 35, the controller 33 corrects the coordinates of the location of the train and determines the route of the train based on the GLONASS / GPS data and the readings of the tonal track chain generators, the number and coordinate of which are recorded in the on-board electronic map.

The control computational controller 33 processes the data coming from the receiving unit 37 ALS / EN, BRBC 42, SKBM 34, module SS 38, ASUT 41, sensor 35 of the distance traveled, SPD 43, EK 40, forms the driving mode, the permissible speed for the automatic guidance system trains SAVP 39 and / or the required mode and braking curve for the automated brake control system ASUT 41, provides the necessary information for visual display on the BIL 36 display unit and the generation of sound signals, generates a report on the execution of commands and signal

- 9 036029 messages, as well as diagnostic information on the rolling stock and the physical condition of the driver for transmission over the radio channel through base stations to the central switch for subsequent transmission to RBC 18 and through SPD 11 OBTN to CPU 1.

The block 37 for receiving signals from track circuits and signals received from the RBC 18 by means of digital radio communication provides the simultaneous availability of information about the state of infrastructure facilities and the route along two channels. The controller 33 provides processing and comparison of the incoming information on two channels, logically checks the data to select the mode and speed of movement at all speeds up to 400 km / h.

The presence of two channels increases the reliability of information delivery and the ability to check it for security requirements. EK 40 is the standard of data on the location of objects throughout the entire train route, allows for verification with the data received from the sensor 35 and the ALS / EH receiving unit 37, as well as from the SS 38.
