Description

The invention relates to devices for receiving high-frequency and low-frequency signal currents flowing along rails of railway tracks, and can be used in the railway industry.

Known locomotive receiver containing a receiving inductive element in the form of a coil made with the possibility of receiving low-frequency and high-frequency signals of rail circuits and an external device module, electrically connected to a receiving inductive element [RU2248899, publication date: 03/27/2005, IPC: B61L25 / 04 ].

Known locomotive receiver of electrical signals of rail circuits containing a receiving inductive element, represented by a coil configured to receive signals of rail circuits of high and low frequency, and a signal processing unit, electrically connected to the receiving inductive element [KR101953096, publication date: 02.28.2019 IPC: B61L1 / 18, B61L27 / 00, G01R15 / 18].

A common disadvantage of the known devices is the high risk of simultaneously losing the ability to receive both low-frequency and high-frequency signals of rail circuits, due to the fact that the reception of signals of both types is provided by one coil, the failure of which entails the failure of the entire receiving inductive element, which is significant degree reduces the reliability of known devices and can lead to an emergency on the railway.

As a prototype, a rail signal electrical signal receiver is selected, comprising a housing inside which a receiving inductive element is installed, made in the form of a winding for receiving a low-frequency signal of rail circuits mounted on a core, and a separately installed winding for receiving a high-frequency signal of rail circuits that does not have a core, connected to the electronic board [RU129471, publication date: 06/27/2013, B61L1 / 02].

An advantage of the prototype over known devices is its higher reliability, due to the fact that the possibility of receiving low-frequency and high-frequency signals of rail circuits is provided by different windings, which allows, if one winding fails, it continues to receive signals of another type by another winding, thereby reducing the risk of an emergency on the railroad. However, the disadvantage of the prototype is a high risk of violating the structural integrity of the winding for receiving a high-frequency signal of rail circuits, as well as a high risk of displacement of the winding for receiving a high-frequency signal of rail circuits relative to the winding for receiving low-frequency signals of rail circuits or the case of the receiver in the manufacture of a receiving inductive element or operating the receiver on a locomotive due to the lack of rigid fixation of the spatial position of the winding for receiving high-frequency rail signals circuits in the receiving inductive element relative to other structural elements of the receiver, as a result of which there may be a distortion of the received signals of the rail circuits, or a significant deterioration in the reliability of receiving signals of the rail circuits, and significantly reduces the reliability of the receiving inductive element, thereby degrading the reliability of the locomotive receiver of the electric signals of the rail chains.

The technical problem to which the utility model is directed is the need to improve the operational characteristics of the locomotive receiver of electric signals of rail circuits.

The technical result, which the utility model aims to achieve, is to increase the reliability of the receiving inductive element of the locomotive receiver of the electrical signals of the rail circuits.

The essence of the utility model is as follows.

The locomotive receiver of the electrical signals of the rail circuits comprises a housing and an electronic board electrically connected to each other and a receiving inductive element represented by windings for receiving high-frequency and low-frequency signals of the rail circuits and the core. Unlike the prototype, windings for receiving high-frequency and low-frequency signals of rail circuits are mounted on the core.

The receiving inductive element provides the possibility of transmitting the signals of currents flowing along the running rails to the electronic board and contains windings for receiving high-frequency and low-frequency signals of rail circuits and a core. The electrical connection of the receiving inductive element and the electronic board can be provided by means of connecting elements, which can be detachably or permanently connected to the windings and the electronic board. In this case, the connecting elements can be represented by wires, cables, paths of conductive material, etc.

The windings for receiving the high-frequency and low-frequency signals of the rail circuits are mounted on the core, which implies the location of each winding on the core, thereby reducing the risk of deformation or relative displacement of the windings in the receiving inductive element during the manufacture or installation of the receiving inductive element, or operation of the receiver, thereby increasing reliability of the receiving inductive element. Moreover, to further improve the reliability of the receiving inductive element by reducing the number of structural elements, the windings for receiving high-frequency and low-frequency signals of rail circuits can be installed on one common core. In this case, the windings can be installed at a distance of 1 to 15% of the core length, which reduces the risk of mutual induction between the windings of the receiving inductive element, thereby further increasing its reliability. If the distance between the windings is less than 1%, the magnitude of the mutual induction between the windings will increase, which will lead to a distortion of the signal of the rail circuit. If the distance between the windings for receiving the signal of the rail circuits is more than 15%, then the length of the receiving inductive element and, as a consequence, the connecting electrical elements of the windings and the electronic board will increase significantly, increasing the risk of damage when installing the receiving inductive element in the housing. The windings can be fixed on the core by means of an adhesive or threaded connection, or by friction interaction, etc.

The receiving inductive element may contain additional windings for receiving high-frequency and low-frequency signals of rail circuits, which can be mounted symmetrically on the core relative to the transverse plane passing through the center of the length of the core, which means that at least two sides of the transverse plane can be installed than one additional winding for receiving high-frequency and low-frequency signals of rail circuits, which increases the reliability of the receiving inductive element enta due to the possibility of induction induction currents in additional windings in case of failure of the main windings. In this case, to reduce the risk of deterioration in the reliability of reception of rail circuit signals when the locomotive moves along a curved section of the railway, an additional winding for receiving a low-frequency signal of rail chains can be installed in the central part of the core equidistant from the center of its length, and an additional winding for receiving a high-frequency signal of rail chains can be installed at the end of the core equidistant from the additional winding to receive the low-frequency signal of the rail circuits. In this case, to further reduce the risk of deterioration in the reliability of reception of rail circuit signals during transverse movement of the receiver to extreme positions relative to the rail when the locomotive moves along a curved section of the railway, the main winding for receiving a high-frequency signal of rail chains can be installed between the main and additional windings for receiving a low-frequency signal of rail chains.

Windings for receiving high-frequency and low-frequency signals of rail circuits provide the possibility of creating an induction current in the receiving inductive element when interacting with the electromagnetic field of the running rail. Windings can be made of conductive material (copper, aluminum, etc.). In this case, the windings can additionally be coated with insulation from varnish, fluoroplastic, film, etc. The windings may contain frames, which can be made in the form of tubes having the shape of the inner surface in response to the shape of the core, which further increases the reliability of the receiving inductive element. Frames can be made of materials with sufficient mechanical and electrical strength, for example, plastic, ceramics, cable paper, electrical cardboard, getinaks, etc. The frames may contain beads that reduce the likelihood of the winding slipping off the frame, which further increases the reliability of the receiving inductive element. Windings for receiving a high-frequency signal of rail circuits provide the ability to receive signals of rail circuits with a frequency of 5 to 35 kHz. Windings for receiving a low-frequency signal of rail circuits provide the ability to receive signals of rail circuits with a frequency of 25 Hz to 1 kHz.

The core provides the ability to concentrate magnetic lines of force. The core may have any cross-sectional shape, for example round, rectangular, triangular, polygonal. The core may be integral and may be formed of plates. The core can be made of materials having ferromagnetic properties, for example, from iron, cobalt, nickel, their alloys, electrical steel, etc.

The electronic board provides the ability to process the signals of the rail circuits received from the receiving inductive element. The electronic board may be represented by a plate of PCB or other electrical insulating structural material. The electronic board contains electronic components that can be represented by microcircuits, elements for creating an oscillatory circuit: reactors, capacitors, resistors, etc. The electronic board may contain inputs for connecting to the windings and conclusions for connecting to external consumers. In this case, the conclusions for connecting with external consumers can be represented by connectors, plugs or terminals, which can be installed in protective tubes.

The housing provides supporting and protective functions. The shape of the housing should provide the possibility of placing an electronic board and a receiving inductive element in it. The housing may have openings for this, which enable the installation of an electronic board and a receiving inductive element inside the housing. In this case, the housing may contain covers that cover the holes. In this case, the receiving inductive element can be fixed inside the housing with glue or compound, which reduces the risk of displacement of the windings inside the receiving inductive element and further increases its reliability. Also, to increase the reliability of fixing the receiving inductive element inside the receiver body, the cover of the holes for installing the receiving inductive element can have a curved profile, which makes it possible to additionally fix the spatial position of the receiving inductive element.

The housing may contain means of attachment to the locomotive, made in such a way that when fixing the receiver, the planes of the turns of the windings are perpendicular to the direction of the electromagnetic field of the rail circuit. In this case, the means of attachment to the locomotive can be performed so that when the receiver is mounted on the locomotive, the transverse plane passing through the middle of the core length coincides with the longitudinal plane passing through the head of the running rail. The fastening means may be threaded fasteners and / or holes in the housing or eyes. The housing can be made of metals, their alloys, composite materials, etc. In this case, the housing may have an insert of non-magnetic material, such as plastic, acrylic or vinyl, which allows the receiving inductive element to interact with the electromagnetic field of the running rail.

The utility model can be made of known materials using known means, which indicates its compliance with the patentability criterion of "industrial applicability".

The utility model possesses a combination of essential features previously unknown from the prior art that the windings for receiving high-frequency and low-frequency signals of rail circuits are mounted on the core, which makes it possible to rigidly fix their structure and spatial position due to the location of each winding on the core and reduce the risk deformation of the windings or relative displacement of the windings when mounting a receiving inductive element or operating the receiver on a locomotive, reducing the risk of distortion Nia received signal loss or the possibility of receiving a signal receiving inductive element, thereby allowing the achievement of technical result consisting in increasing the reliability of the inductance element receiving electrical signals locomotive receiver track circuits, improving performance characteristics of the locomotive receiver electrical signals track circuits.

The locomotive receiver of the electrical signals of the rail circuits comprises a housing 1 with a cable outlet in the form of a tube 2, with fastening means to a locomotive represented by bolts 3 for mounting on a locomotive bracket (not shown in the figures), a cover 4 of the receiving inductive element, cover 5 of the electronic circuit board covers 6 holes for mounting a receiving inductive element, an electronic board 7 with amplifiers (not shown in the figures), a band-pass filter (not shown in the figures) and a receiving inductive element containing frames 8 on which windings 9 are installed for receiving a high-frequency signal of rail circuits, and frames 10 on which windings 11 are installed for receiving a low-frequency signal of rail circuits, as well as a core 12.

The utility model works as follows.

A locomotive receiver of electrical signals of rail circuits is manufactured and assembled at the manufacturer, while the location of the windings 9 and 11 on the core 12 makes it possible to arrange the receiving inductive element in the housing 1 with a reduced overall height and width. The locomotive receiver of electrical signals of the rail circuits is perpendicular to the running rail, suspended above the running rail and fastened to the bracket in front of the first locomotive wheel pair by means of bolts 3, while fastening is accompanied by monitoring the condition of locating the locomotive receiver in such a way that the middle of its length is on a straight section of the railway track was located above the center of the running rail. In this case, the locomotive receiver is additionally fixed with safety suspensions (not shown in the figures). Next, over the second running rail, a second locomotive receiver is installed on the locomotive by analogy with the previous locomotive receiver, after which the electronic boards of 7 locomotive receivers are electrically connected to the locomotive equipment (not shown in the figures), and the locomotive is put into operation.

During operation, the locomotive moves along the railway track, along the rails of which the signal currents of the automatic continuous locomotive signaling system (ALSN) with a frequency of 25, 50, 75 or 175 Hz and the signal currents of the automatic train braking control system (SAUT) with a frequency of 19.6, 27, 0 or 31.0 kHz. In this case, due to the flow of signal current through the rails, an alternating magnetic field is formed in which locomotive receivers move. In this case, in the windings 9 for receiving a high-frequency signal of rail circuits and the windings 11 for receiving a low-frequency signal of rail circuits, an induction current is induced. Due to the core 12 of the locomotive receiver, the concentration of magnetic lines in the locomotive receiver is carried out, due to the symmetry of the location of the windings relative to the transverse plane passing through the middle of the core length, as well as due to the location of the middle of the length of the locomotive receiver above the center of the running rail, when moving along a curved railroad track (i.e., when the running rails turn to the right or left), the winding 9 and the winding 11 located at one locomotive receiver side, in the direction of the running rail, while there is a commensurate approximation windings 9 and the coil 11 disposed on the other side of the locomotive receiver to the running rail. As a result of this, the total EMF is stabilized on two windings of the locomotive receiver, equidistant from the center of the locomotive receiver and designed to measure signals of the same frequency (high or low) and, as a result, the distortion of the signals entering the receiving inductive element is reduced.

Induction currents induced in the windings 9 for receiving the high-frequency signal of the rail circuits and the windings 11 for receiving the low-frequency signal of the rail circuits are fed through the wires to the electronic board 7. On the electronic board 7, the signal is amplified by microcircuits, after which the currents are filtered by means of the vibrational circuits of the strip filter, providing shunting of high-frequency interference, resulting in the received electrical signals that carry information about the codes in the rail circuits ALSN SOUTH travel devices, are transmitted via wires in the locomotive apparatus.

Thus, the achievement of the technical result is achieved, which consists in improving the mass and size characteristics of the locomotive receiver of electric signals of rail circuits with the concurrent preservation of its functionality, thereby improving the operational characteristics of the locomotive receiver of electric signals of rail circuits.
