Description

The invention relates to railway transport and is intended for use on station sections of the track on the main and industrial railway transport as a means of controlling the freedom of station tracks and switch sections as an autonomous means, and as part of relay-processor, microprocessor or electrical centralization of arrows and signals, as well as a key dependence for any type of train traction.

The known system of microprocessor centralization (MPC) ZBS2000, based on the system of cross-country alarm BUES2000, supplied by Scheidt & Bachmann. The following technological units may be included in the coverage area of the ZBS2000 MPC: station, checkpoint, points of adjacency or branching, interfacing with the blocking system at the beginning and end of the section.

Each of these technological points has its own intelligent logic device, which uses a secure computing system and to which the necessary number of blocks is connected to control arrows, traffic lights and axis counters.

In the ZBS2000 system, track axle counters are used to control track clearance. The wheel passage sensors included in their composition consist of two small inductive loops embedded in a compact housing that is attached to the rail.

A control device located in the immediate vicinity of the path analyzes the signals from the sensors and transmits information about each axle traced and its direction of movement along the CAN bus to the MPC computing system. Calculation of the number of axles and the formation of a notice on the vacancy or occupation of a track section are carried out by the control devices of the MPC.

On station tracks, including turnouts, axis counters are also used. It is possible to form a common section of the control of freedom from several arrows and segments of the path between them in each neck of the station. On the stages between technological points of the ZBS2000 system, end-to-end control of free paths is provided. To do this, axis counters are installed at the beginning and end of the drive, and the axis counter at the end of the drive is installed next to the input signal of the neighboring station with some overlap relative to the axis counter of the station area. Data on the number of axles is transmitted via a linear communication network for processing and decision-making (World Railways, No. 1, 2005).

The known system for controlling the freeness of track sections by the method of counting axes (ESSO), developed and manufactured by the Scientific and Practical Center "Promelectronics".

The responsible element of the ESSO system is the sensor for monitoring the passage of the axes of the rolling stock.

ESSO is a microprocessor system that provides automatic control of the free (busy) sections of the track of any complexity and configuration (with any number of branches).

The structure of the ESSO system includes floor and guard units. Floor devices (counting points), designed to count the number of axles passed, consist of reversible induction-type rail sensors with a set of fasteners on the rail soles, floor-mounted electronic modules that form a counting point (SP), delimiting adjacent sections of the track like an insulated joint. Guard devices analyze information about the number of axles passed and make a decision on the free or busy sections of the track. Information about the number of axles passed through the line is transmitted to a central point where they process information received from two, three or four joint ventures and decide on the condition of the area being monitored. A controlled section refers to a section of a track fenced by a joint venture from all ends (found on the Internet).

A device is known for implementing a method for determining the freedom from rolling stock of a railway haul, which is two half-sets installed on the counting sections of stations that limit the haul. Each half-set contains rail sensors installed on the control track section, the signal from which is fed through the driver to the input of the receiver block, the data from which are sent to the interface unit with axis counters (BISO), which generates code messages to the local highway and receives code messages from the local highway , an interface unit with electrical centralization (BIEC), to the input of which signals are used to control the employment of the enumeration section, arrival from the adjacent station and departure to the adjacent an output whose output controls the inclusion of a relay that generates code messages to the local highway of the locomotive radio channel and receives code messages from the local highway, an antenna connected to the radio modem controlled by the interface unit with the radio channel (BIRK), which generates code messages to the local highway and receives code messages from a local highway, and a control unit (CU), generating code parcels to the local highway and receiving code parcels from the local highway (RF patent for invention No. 223 8866, B61L 21/06).

The device operates as follows.

During the passage of the rolling stock, PD 17 ₁ , ..., 17k and PSO 14 ₁ -14k generate electrical signals that carry information about the fact that the axis of the rolling stock is traced and the direction of its movement. The signals from the PD 17 _1, ..., 17k via a specialized cable are sent to the NSRB 16 ₁ , ..., 16k, which count the number of axes fixed by the PD 17 ₁ , ..., 17k taking into account the direction of their movement. PRB 6 continuously polls PSO 14 ₁ -14k in turn, which, upon receipt of a request, transmit information about the number of axes traced to PRB 6, which processes the received information through two independent computing channels and controls the operation of the BPR 4 travel relays.

Self Test Mode.

In the process, the devices NSRB 16 ₁ -16k are continuously independently tested, they monitor the operability of PD 17 ₁ -17k and the correct position of PD 17 ₁ -17k relative to the rails. In the event of a malfunction or improper position of the PD 17 ₁ -17k relative to the rails of the NSRB 16 ₁ -16k, it goes into a protective state, which leads to the shutdown of the corresponding track relay BPR 4 at PET 1.

Failure mode of operation of the PSO.

In the event of a malfunction in any JI 14 ₁ -14k, JI trip relays adjacent to the JI, which is in the malfunction mode, remain de-energized after the rolling stock has actually been released from the controlled section (section). To eliminate the false occupation of the track sections and switch sections, the BIVR 5 artificially restores the track section or switch section by pressing the appropriate button, individual for each track section or switch section.

Thus, the proposed device for monitoring the freedom of the station sections of the track provides: continuous monitoring of the state of freedom of tracks and switch sections of any configuration; stable operation when switching power feeders; the possibility of selective artificial restoration of the initial state after a malfunction, as well as after performing maintenance work or equipment replacement; the possibility of accumulating information, recording events and conditions of controlled track sections and switch sections using any personal computer with a significant reduction in hardware and cable networks, reducing the cost of equipment for track sections compared to rail chains, reducing the cost of maintaining signaling devices and track structure, reducing downtime of rolling stock and increasing throughput by reducing the time required to restore signaling devices.
