Description

The invention relates to devices for signaling, centralization and blocking in railway transport, in particular to systems for interval regulation of train movement on sections, and can be used mainly in block sections, the track infrastructure of which allows the movement of passenger trains at speeds above 160 km / h.

A known system of interval regulation of train traffic on the stages, which implements a method of interval regulation of train traffic during centralized traffic control and three-digit auto-blocking with traffic lights, contains three-digit auto-blocking (AB) devices with rail circuits connected to the postal devices of electrical centralization (EC) of stations that limit the stretch, and a dispatch control center, which is connected by a line of trunk communication with post devices of EC, while dispatching distal radio link digital communication management center connected to the onboard train locomotive control units involved in the dispatch control, on each of which side control device connected with the onboard satellite navigation receivers (RU 2387563 Cl, B6lL 27/00, 27.04.2010).

In the known system of interval regulation of train movement on stages, safe speeds and intervals between simultaneously following trains on stages are automatically supported by locomotive on-board control devices together with AB devices. On each of the locomotives, the on-board control unit continuously calculates the current location coordinates and the speed of the train, taking into account the auto-driving program. Taking into account information about the length of the train and its speed, as well as the length of the block section along the route, the on-board device periodically calculates the predicted time of release of the next block section and sends this data via the digital communication radio channel to the control center. Based on the received data, the calculated time for changing the yellow light to the green light at the second traffic light in the direction of the train is transmitted to the control center based on the received data.

The disadvantages of the known system are the high cost due to the large number of expensive equipment for long-range digital radio communications and supervisory control.

A well-known interval control system that uses automatic locomotive signaling of a continuous numeric code (book "Devices of railway automation and telemechanics", edited by D.V. Chaliagin, M .: Route, 2006, p. 314-322, Fig. 6.3) .

The known system of interval regulation includes blocks of track equipment for automatic locomotive signaling of a continuous numeric code (ALSN) installed on block sections of the stage, and blocks of locomotive equipment of automatic locomotive signaling for a continuous numeric code included in the on-board control unit of a train locomotive involved in the carriage the process on the stage, the inputs of each block of track equipment are connected to the outputs of the devices installed on the block section auto-locks with traveling through traffic lights and rail chains, and the exit - to the rail line of the block section.

In the known system, track devices monitor the condition of the sections and transmit code signals along the rail lines. Code signals carry information on the permissible train approaching speed with the auto-blocking track signals. Depending on the indications of the traffic light to which the train is moving, certain speeds are controlled.

The main disadvantage of the known system is the low information content, which forces the transmission of the same code signal 3 in front of a traffic light with a green light and in front of a traffic light with a green flashing light. The small significance of the numerical code is especially evident when the train approaches the input traffic lights of stations having turnouts with crosses of different steepness. In these cases, the readings of the input traffic light are more accurate than the locomotive ones, since the different readings of the input traffic light are one yellow; two yellow with a green stripe and other lights - are transmitted to the locomotive with the same code signal Ж, which is unacceptable when organizing the movement of high-speed trains, on the way of which an increased number of obstacles.

In addition, the system has insufficient reliability. Failures in the operation of ALSN devices are caused, in particular: by malfunction of locomotive equipment, distortions of code signals due to traction current noise or imperfection of coding schemes for rail circuits. Distortion of code signals depends on traction current levels, speed, meteorological conditions, etc. These failures are manifested in the fact that at a locomotive traffic light a fire lights up that does not correspond to the received code signal, which reduces the throughput, especially when driving high-speed trains.

The closest technical solution is the system of interval regulation of train traffic on the stages, containing on the way a three-digit auto-lock (AB) device with rail chains of block sections, track equipment blocks of which are connected to each other by a communication line and connected to station centralization devices (EC) of stations , limiting the drive, and on locomotives the control unit includes blocks of on-board devices for automatic locomotive signaling ALSN of a numerical code (Leonov A.A. technical maintenance of automatic locomotive signaling. "M .: Transport, 1982, p. 256 and Kazakov AA, Kazakov EA" Auto-blocking, automatic locomotive alarm and hitchhiking. "M .: Transport, 1980, p.30, fig. 11).

A disadvantage of the known system is the low information content, since the driver has information about the freeness in front of only the three closest block sections ahead of the train, which is insufficient for passenger trains to travel at speeds above 160 km / h and causes a small bandwidth.

The technical result of the invention is to increase the information content and reliability of the system through the use of an additional information channel about the freedom of more than three block sections of the stage. This allows you to increase the throughput and efficiency of high-speed trains on the stretch using the minimum cost of equipment for block sections of the track and on-board control devices for locomotive signaling.

The technical result is achieved by the fact that the interval control system for the movement of trains on the train contains blocks of track equipment of continuous automatic locomotive signaling installed on block sections of the train and connected by a communication line on the locomotive of each train involved in the transportation process on the train the on-board control device includes a unit of locomotive equipment of automatic continuous locomotive signaling, at each input block The track equipment block is connected to the outputs of three-digit auto-blocking devices installed on the block section with traffic lights and rail circuits, and the output is to the block section rail line, at the beginning of each block section, a transceiver with a low-power transmitter is installed, the input / output of which is connected through the interface block to the output / input of the track equipment block, on-board high-speed train locomotives are additionally equipped with an on-board transceiver with a low-power transmitter and an on-board m a pairing interface, the first port of which is connected to the output / input of the on-board transceiver device, the second port is connected to the output / input of the on-board control device, and the output is connected to the input of the driver’s display, while the transceiver devices of the block sections and the on-board transceiver device are arranged self-organization of a digital radio communication network of the frequency range ISM or GSM.

The system includes, at stations limiting the stage, station posts for electric centralization, the inputs / outputs of which are connected via the communication channel to the corresponding outputs / inputs of the track equipment units.

The drawing shows a structural diagram of an embodiment of the proposed system of interval regulation of train traffic on the hauls.

The system of interval regulation of the movement of high-speed trains on the stages contains blocks 1 of track equipment of automatic continuous locomotive signaling (ALSN) installed on block sections 2 of the stage and connected by a communication line, and block 3 of locomotive equipment ALSN included in the on-board control device 4 trains involved in the haulage process. The inputs of each block 1 of the track equipment are connected to the outputs of the automatic blocking devices 6 installed on the block section 2 with traffic lights 7 and with rail circuits, and the output is connected to the rail line 8 of block section 2.

At the beginning of each block section 2, a transceiver 9 with a low-power transmitter is installed, the input / output of which is connected through the interface unit 10 to the output / input of block 1 of the ALSN track equipment.

On locomotives 5 of high-speed trains, an on-board transceiver 11 with a low-power transmitter and an on-board interface module 12 are additionally installed, the first port of which is connected to the output / input of the on-board transceiver 11, the second port is connected to the corresponding input / output of the on-board control device 4, and the output is connected to the display input 13 of the train locomotive driver 5.

At stations limiting the stage, station posts 14 are installed for electric centralization, the inputs / outputs of which are connected via a communication channel to the corresponding outputs / inputs of blocks 1 of the track equipment.

In this case, the transceiver 9 is configured to self-organize a digital communication network of the frequency range ISM or GSM, in which each intermediate transceiver 9 functions as a router and a relay.

Each on-board module 12 interface includes a controller (not shown), which processes and converts signals in accordance with the task. The controller’s electronic memory contains unique addresses of the traveling transceiver devices 9 of the block sections 2 of the stage, the numbers of the corresponding traffic lights 7 and / or the numbers of the block sections 2 themselves, as well as information about the sequence of placement of the transceiver devices 9 along the train route.

Each track block 10 interface includes a controller (not shown), in the memory of which is stored the identification number of the transceiver devices 9 of the neighboring block sections 2, as well as information about the possibility of trains traveling at speeds above 160 km / h. Information on the possibility of trains traveling at speeds above 160 km / h is determined by the state of the track infrastructure of block 2 and is preliminarily entered through its block 1 of track equipment ALSN via the communication line by the train dispatcher from station 14 of electric centralization.

Block 3 track equipment ALSN each block section 2 includes a track device coding ALSN (not shown).

Unit 3 of locomotive equipment ALSN includes an automatic locomotive alarm, auto-stop, a device for checking the alertness of a driver, a device for controlling the speed of a train and an automatic driving device (not shown in the drawing).

The interval control system operates as follows.

With automatic self-locking (AB), traffic lights 7 are the main means of regulating the movement of trains on the stage. Blocks 1 track equipment ALSN using devices 6 three-digit auto-block control the status of the block sections 2 and transmit code signals via rail lines 8 to block 3 of locomotive equipment ALSN. Block 3 of locomotive equipment ALSN reads code signals, processes them, and provides information to the driver’s cab about the status of free or busy three block sections 2 that are closest to the locomotive signaling device in the direction of the train.

When the locomotive 5 of the high-speed train approaches the next block section 2 with the green light of the traffic light 7, the on-board pairing module 12 determines the unique address of the track-and-receive device 9 of this block-section 2 and sends it to the transceiver device 11, which begins to continuously call the transceiver device 9. The transceiver the device 9, which was previously in standby mode with a very low current consumption, switches to communication mode and begins to continuously call the transceiver Property 9 of its neighboring block 2 using its known call address. The transceiver 9 of the neighboring block 2 similarly switches from the standby mode to the communication mode, starts to call the transceiver 9 of the next neighboring block 2. In this way, a radio communication network is established between the transceivers 9 of the block sections 2 of the stage and the transceiver device 11, in which each intermediate transceiver 9 functions as a router and a relay.

At the same time, having received a call signal, the transceiver 9 of each block section 2 through the pairing unit 10 requests the block 1 of the track devices about the free state of the block section 2. Block 1 of the track equipment sends code signals characterizing the state of this block to the input of the block 10 section 2. The pairing unit 10, taking into account the data on the state of the track infrastructure of the block-section 2, stored in its memory, generates an information signal, including information about the freeness of the block-section 2 and the permissible speed a high-speed train in this block-section 2, and directs it to the input of the transceiver 9, which directs it through the radio channel to the transceiver 11.

From the output of the transceiver device 11, the information signal enters the on-board module 12 interface, which carries out its identification, the corresponding processing and conversion, and then sends to the block 4 on-board control devices and the display 13 of the driver.

The on-board interface module 12 allows each time the establishment of radio communication with only one transceiver device 9 in the direction of the high-speed train 5. To eliminate communication errors with the transceiver devices 9 of the other block sections 2, the on-board interface module 12 checks the sequence of alternating unique addresses of the transceiver devices 9, traffic lights 7 and block sections 2.

The digital radio communication channel in the ISM frequency range provides a communication range without intermediate relay of the order of 1.5-2 km, and the GSM channel up to 5 km or more. Due to this, the driver of a high-speed train, in addition to the ALSN information, receives information on the free state and permissible speeds according to the conditions of the track infrastructure of more than three block sections 2. If a large number of block sections 2 are free with permissible speeds, for example, up to 250 km / hour, the speed of a high-speed train with each subsequent block-section 2 can gradually increase to 250 km / h.

In addition, in case of failure of locomotive devices, caused, for example, by a malfunction of locomotive equipment, distortion of code signals due to traction current interference, the driver receives information on the state of block sections 2 of the haul, permissible speed of travel, over the communication network organized by transceiver devices 9 him.

Thus, the proposed technical solution allows to increase the information content of the provided data and the increased system reliability due to the use of an additional information channel on the freedom of block sections of the 2nd section of more than three block sections of the section, which allows to increase the throughput and efficiency of high-speed trains on the section when using minimum equipment costs for 2-way block sections and on-board locomotive signaling control devices.
