Description

The utility model relates to railway automation and is intended to automate the process of measuring signals and interference in rail lines.

Currently, the measurement of signal and interference parameters in rail lines is carried out by simulating the movement of rolling stock using a hand truck mounted on a rail line. Such measurements are carried out only in specially designated technological windows or in the intervals of the monitored area free from rolling stock.

The measurement of signal and interference parameters in rail lines by known devices is discrete and, as a result, low informative for decision making at the time of failure of automatic continuous locomotive signaling devices of the continuous type of action (ALSN), which are disadvantages of the known devices.

A device is known for measuring the parameters of signals and noise in rail lines, the principle of which is based on the inductive reading of information from each rail thread [RF patent No. 95624, IPC B61L 23/16, B61L 25/06 (2006.01). “A device for measuring parameters of signals and noise in rail lines” / Leushin VB, Anchikov SV, Bystrov SV, Rogulin VA; SamGUPS (RF). - No. 2010104505/22; claimed 02/09/2010; publ. July 10, 2010, BI No. 19].

A device for measuring parameters of signals and noise in rail lines contains a signal sensing unit, an artificial asymmetry unit, a signal recording unit, an information input unit, and a regulatory shunt.

The signal sensing unit is designed to accept AC signals and noise from rail lines, made in the form of two receiving locomotive coils. The block of artificial asymmetry is intended for the initial installation of a predetermined level of asymmetry of the rail line and the receiving path of the device. The signal recording unit is designed to measure, record and store perceptual results for subsequent processing. The information input unit is intended for the operator to enter into the signal registration unit information on the factors accompanying the measurement: the voltage and current in the power transmission wires, the current value at the output of the useful signal source, the ordinate of the location of the insulating joints and turnout elements, and the ordinate of the suction line connection to the rail network etc. The standard shunt is designed to simulate a locomotive’s wheelset when moving along rail lines.

An artificial asymmetry unit, a signal registration unit, an information input unit are installed on the platform of the hand truck, and the receiving locomotive coils of the signal sensing unit and the regulatory shunt are suspended from the bottom of the platform above the rail line, with each receiving locomotive coil located in a certain way above the corresponding rail thread.

The input of each receiving locomotive coil is inductively coupled to a corresponding conductive rail thread. The electrical output of each said coil is connected respectively to the first and second inputs of the artificial asymmetry block, the output of which is connected to the first input of the signal recording block. The second input of the signal recording unit is connected to the output of the information input unit used by the operator.

The device operates as follows.

Measurement of signal and interference parameters in rail lines is carried out at various points on a controlled section of the rail line.

Before starting work, the hand truck is mounted on a rail line at one of the measurement points for signal and interference parameters. Next, the operator moves the hand truck to the measuring point at which the DC component of the current in the rail lines is measured and by the value of which a certain level of asymmetry of the rail line and the receiving path is established in the block of artificial asymmetry.

Further, at the measurement point, the operator imposes a standard shunt on the rail line, which leads to the closure of the flow path of signal and noise currents and to induce EMF in the first and second receiving locomotive coils of the signal sensing unit. The electrical signals from each receiving coil entering the artificial asymmetry block are corrected in it in accordance with the value of the DC component of the current in the rail lines.

The resulting electrical signal enters the signal registration unit, at the same time text data about the electromagnetic sources accompanying the measurement, the location of the platform and the location of the signal and interference source, which are visually determined by the operator, are received from the information input unit to the said unit.

In the registration unit, the resulting electrical signal and text data are combined into a data packet for each measurement point with its subsequent storage.

The next measurement of the parameters of signals and interference in a different coordinate of the path is carried out in a similar way after moving the hand truck to this point.

As a result, a data packet archive is generated in the signal registration block, which is delivered by the operator to the processing station for the measurement results.

The operator, analyzing the resulting archive, draws conclusions about the factors and the degree of influence of interference on the parameters of signals transmitted along the rail line in certain places.

The advantage of the device for measuring the parameters of signals and interference in rail lines is the sufficient reliability of the measurement results, which is due to the measurement of parameters of signals and interference in rail lines is carried out in conditions close to operational.

The disadvantage of the device for measuring the parameters of signals and interference in rail lines is the low information content of the measurements, which is due to discrete measurement of the parameters of signals and interference in rail lines only at individual points on the controlled section of the rail line, as well as the operator’s visual determination of the coordinate of the measurement point and the source location signals and interference.

Another disadvantage of the known device is the additional organization of the movement of trains on a controlled section of the rail track according to the variant schedule, which is due to the need to measure the parameters of signals and noise in the rail lines only in specially designated technological windows.

The closest in the set of essential features with the claimed solution is a device for measuring parameters of signals and interference in rail lines, the principle of which is based on inductive reading of information from each rail thread [RF patent No. 106204, IPC B61L 23/16, B61L 23/06 / Leushina V.B., Volik V.G .; SamGUPS (RF). - No. 2011105545/11; claimed 02/14/2011, publ. 07/10/2011, BI No. 21.]

A device for measuring parameters of signals and noise in rail lines contains a signal sensing unit, an artificial asymmetry unit, a signal recording unit, an information input unit, a regulatory shunt and a wheel speed sensor of a hand truck.

The signal sensing unit is designed to accept AC signals and noise from rail lines, made in the form of two receiving locomotive coils.

The block of artificial asymmetry is intended for the initial installation of a predetermined level of asymmetry of the rail line and the receiving path of the device.

The signal recording unit is designed to measure, record and store the results of signal perception for subsequent processing.

The information input unit is intended for the operator to enter into the signal registration unit information on the factors accompanying the measurement: the voltage and current in the power transmission wires, the current value at the output of the useful signal source, the ordinate of the location of the insulating joints and turnout elements, and the ordinate of the suction line connection to the rail network etc. The standard shunt is designed to simulate a locomotive’s wheelset when moving along rail lines.

An artificial asymmetry unit, a signal registration unit, an information input unit are installed on the platform of the hand truck, and the receiving locomotive coils of the signal sensing unit and the regulatory shunt are suspended from the bottom of the platform above the rail line, with each receiving locomotive coil located in a certain way above the corresponding rail thread.

The wheel speed sensor of the rolling stock of the hand truck is designed to count the wheel speed of the hand truck to the point of measurement of signal and interference parameters and is installed on the hand truck wheel for the duration of the monitored section.

The input of each receiving locomotive coil is inductively coupled to a corresponding conductive rail thread. The electrical output of each said coil is connected respectively to the first and second inputs of the artificial asymmetry block, the output of which is connected to the first input of the signal recording block. The second input of the signal recording unit is connected to the output of the information input unit used by the operator. The third input of the signal recording unit is connected to the output of the wheel speed sensor of the hand truck, the input of which is connected to the wheel of the hand truck.

The device operates as follows.

Measurement of signal and interference parameters in rail lines is carried out at various points on a controlled section of the rail line.

Before starting work, the hand truck is mounted on a rail line at one of the measurement points for signal and interference parameters. Next, the operator moves the hand truck to the measuring point at which the DC component of the current is measured in the rail lines, by the value of which a certain level of asymmetry of the rail line and the receiving path is established in the block of artificial asymmetry.

At the measurement point, a regulatory shunt is imposed on the rail line by the operator, which leads to the closure of the flow path of signal and interference currents, as well as to inducing EMF in the first and second receiving locomotive coils of the signal sensing unit.

The electrical signals from each receiving coil entering the artificial asymmetry block are corrected in it in accordance with the value of the DC component of the current in the rail lines.

The resulting electrical signal enters the signal registration unit, at the same time text data on the electromagnetic sources accompanying the measurement, which are visually determined by the operator, as well as from the hand wheel wheel speed sensor - digital data on the number of wheel turns of the hand truck are sent to the said unit from the information input unit .

Thus, during each measurement, the resulting electrical signal of the artificial asymmetry block, the text data of the information input unit and the digital data of the wheel speed sensor of the hand truck, which are combined into a data packet for each measurement point with its subsequent storage, are recorded simultaneously in the signal registration block.

The next measurement of the parameters of signals and interference in a different coordinate of the path is carried out in a similar way after moving the hand truck to this point.

As a result, a data packet archive is generated in the signal registration block, which is delivered by the operator to the processing station for the measurement results.

The operator, analyzing the resulting archive, draws conclusions about the factors and the degree of influence of interference on the parameters of signals transmitted along the rail line in certain places.

The advantage of this device is to increase the information content of measurements of signal and interference parameters in rail lines, which is due to increased accuracy in determining the coordinates of the measurement point and the location of the signal and interference source.

However, the information content of measuring parameters of signals and interference in rail lines remains insufficient for the timely detection of signals and interference at the time of failure of the locomotive equipment, which is a disadvantage of the known device. This is due to discrete measurement of signal and interference parameters in rail lines only at individual points on a controlled section of the rail line.

Another disadvantage of the known device is the additional organization of the movement of trains on a controlled section of the rail track according to the variant schedule, which is due to the need to measure the parameters of signals and noise in the rail lines only in specially designated technological windows.

The problem to which the claimed utility model is directed is to develop a device for measuring the parameters of signals and interference in rail lines, increasing the information content of measurements, ensuring the organization of train movement on a controlled section of the rail track according to the standard schedule by continuously measuring the parameters of signals and noise in the rail lines at each point of the monitored section of the rail track.

To solve the problem, a device for measuring parameters of signals and noise in rail lines, comprising a signal sensing unit, designed to receive signals and AC noise from rail lines and made in the form of two receiving locomotive coils, a signal recording unit for measuring, recording and storing the results of signal perception for subsequent processing, and the wheel speed sensor of the rolling stock, designed to count the speed of its wheels, with each input I have a locomotive coil of the signal parameter sensing unit, inductively connected to the corresponding conductive rail thread, it contains an information transmission unit for transmitting the accumulated data packet archive of the signal registration unit, an information receiving unit for receiving the accumulated data archive of the data packet of the signal registration unit, determination unit the coordinates of the locomotive, designed to fix the coordinates of the point of movement of the locomotive according to the wheel speed sensor the stand and the information processing unit, intended for further processing of the received information, while the output of each receiving locomotive coil of the signal parameter sensing unit is connected to the corresponding inputs of the signal registration unit, the third input of which is connected to the output of the locomotive coordinate determination unit, the input of which is connected to the speed sensor locomotive wheels, the output of the signal recording unit is connected to the input of the information transmission unit, the output of which is connected to the input of the information receiving unit, output it is connected to the input of the information processing unit, each receiving locomotive coil of the signal parameter sensing unit is mounted on the frame of the first locomotive trolley above the corresponding rail line, the signal recording unit and the locomotive coordinate determination unit are located in the locomotive driver’s cab, the information transmission unit is made in the form of a radio transmitter and located on the frame of the first locomotive trolley above the center line of the rail line, the information receiving unit is made in the form of a radio receiver and is located traffic light before the inlet of each station in the intertrack spaces, information processing unit installed on the station, turns the wheel sensor mounted on the wheel of a rolling stock.

The set of essential features of the proposed solution differs from the set of essential features of the known solution by introducing new units into the device, namely, an information transmitting unit, an information receiving unit, a locomotive coordinate determining unit and an information processing unit, new relationships and arrangement of blocks in it.

The presence of a set of essential distinguishing features indicates the conformity of the proposed solution to the patentability criterion of the utility model of "novelty."

The introduction to the device for measuring the parameters of signals and interference in the rail lines of the information transmission unit, the information receiving unit, the locomotive coordinate determination unit and the information processing unit, leading to the formation of new relationships in the device and the new location of the units, provides an increase in the information content of measurements on average 1 , 8 times.

The figure shows a block diagram of a device for measuring the parameters of signals and interference in rail lines, illustrating the performance and "industrial applicability" of the claimed device.
