Description

The field of technology to which the invention belongs

The invention relates to the field of railway automation and can be used to control the movement of trains.

State of the art

There is a known method for regulating the movement of trains using radio communication devices, with the help of which information is transmitted from the post of electrical centralization of the EC to the locomotive L information about the state of the running track circuits of the RC, taking into account the location of L, which is determined by the GLONASS PGL receiver. The station computer The computer calculates the length of the free section of the track in front of the train, determines the configuration of the route.

The state of the RL haul rail lines is monitored by tonal track circuits of the SEC using a two-wire line for powering the SEC LP and step-by-step operation of the LRS linear distributors, and a two-wire LC control line for transmitting information about the state of the RC to the EC posts of adjacent stations.

The cable lines of the LP and LC are laid from the middle of the haul to the stations, the tonal track generator PGN is connected to the LP at the EC post, and the tonal track receiver PPR is connected to the LC; under the influence of the EVMS, the PGN sends a series of pulses (20-30 pulses) to the LP, between which there is an interval that performs the functions of the CS frame synchronization signal. The pulses are separated by boundaries where the signal phase changes to the opposite phase.

At the borders of the DC, track boxes PK are installed with equipment for the supply end PKg (generator) or the receiving end PKp, PKp and PKg alternate in a checkerboard pattern; the outputs of the ST counters located in the PC are connected through the logical element OR to the electronic key EC so as to carry out cyclic control of the states of the RC; information is cyclically transmitted to the PPR about the state of the RC via the LC, while the receiving end of the RC is connected to the PPR by means of path transformers PT and LC. The amplitude of the signal indicates the state of the radar (busy/free, serviceable/faulty). L transmits information about the state of the RC located in the zone of control of the ZK.

In the event of a cable core break in the LC or LP circuit, a spare core (five-core cable) is provided to restore the operation of the device.

The disadvantage of this method is that it takes a long time to eliminate even a single damage - a break in the cable core. Elimination of damage during a short circuit of the cable cores requires even more time and two spare cores to replace the cores with damaged insulation.

The presented method [Patent. 2732181 (RF). Way to regulate the movement of trains / Polevoy Yu.I. - Published. 09/14/2020 Bull. No. 26, IPC B61L 23/16.] is selected as a prototype.

Disclosure of invention

The technical result that this technical solution is aimed at is to reduce the time to search for and eliminate damage to the linear cable laid on the haul, and, consequently, the delay time of trains in the event of a cable core break or insulation failure between two cable cores using one additional core. The damage search and repair algorithm consists in the fact that when a cable core breaks, two employees of the Automation, Telemechanics and Communications distance (ShN mechanic and CMM fitter), located at the ends of the damaged cable, simultaneously disconnect one of the cable cores from the circuit to which it was connected . Instead, a spare core is connected. If it was the damaged core that was replaced, then the operation of the devices is restored. The ends of the damaged core are isolated from the electrical circuits of the PC track boxes. If the operation of the device is not restored, then similar operations are carried out with other cores.

In the event of a short circuit between two conductors, the damage is eliminated in the same way. A short circuit between two conductors with damaged insulation is not eliminated. Both cores remain in the circuit and are used as one wire.

Without taking into account the delivery time of the repair personnel, the restoration of a damaged cable takes several minutes (open the covers of the travel boxes, alternately remove the plug of each core (four cores in total) from the sockets, connect a spare core instead of the damaged core).

The redundancy device of the system for monitoring the status of rail lines contains a circuit (corresponds to the prototype) mounted at the EC post and in track boxes at the track at the boundaries of the rail circuits, a station computer, a track generator and a track receiver are provided at the EC post, a rectifier and a battery are mounted in the track boxes, an electronic key, a device for fixing a phase change and a device for fixing a signal of cyclic synchronization, a path transformer, a counter, a logical element OR and four tuning bows, differs in that the way box is additionally equipped with a cable core switching board, which allows quick replacement of a broken core with a spare one.
