Description

The technical solution relates to the field of rail transport systems, in particular, to auxiliary equipment of railway systems, and is a special vehicle equipped with instrumentation to check the condition of the track during its operation, construction and repair work.

A mobile flaw detector-tracker is known, characterized in that it is made in the form of a removable trolley mounted on rails, on which an automated diagnostic complex is equipped, equipped with a positioning system, track measuring equipment, flaw detection equipment and a microprocessor system (patent for utility model No. 62571, MPK V61K 9/08, publication date 04/27/2007, Bull. No. 12, “Defectoscope-track gauge”). The measurement data of the mobile flaw detector-tracker are transferred to the data storage device for storage, they are read by the microprocessor from the storage device and transmitted to the display device for preliminary operational control, in addition, the obtained measurement data is sent to an external server for further analysis in order to carry out rail track diagnostics.

The disadvantage of this device is that it does not provide a decoding of the measurement results, including the relative position of the rail threads, indicating the identified violations and recommendations for their elimination, as well as their visualization at the place of monitoring.

A device is also known for measuring the geometric parameters of railway rails, including a rail carriage, which includes a frame with a folding operator handle on which wheels are mounted, wheel pressing units connected to a signal preprocessing unit, sensors, including an odometer sensor, a secondary a power source with an electrical connector for connecting to an electric current network, which, in turn, is connected to the battery, while a wearable computer connected to

to the signal preprocessing unit (patent for utility model No. 62612, IPC ЕВВ 35/00, publication date 04/27/2007, Bull. No. 12, “Device for measuring geometric parameters of railway rails”).

The known device provides the ability to view the measurement results of the control and detected malfunctions on the screen of a mobile computer, however, a complete analysis of the parameters of the studied section of the track with detected deviations from the set standards and with subsequent recommendations for their elimination is possible only in the post-processing mode on an external stationary computer using special software tools.

The objective of the proposed technical solution is to increase the efficiency of rail track diagnostics by improving the quality of measuring track parameters, their analysis and visualization directly on the controlled site.

The problem is solved due to the fact that the track measuring complex, containing a removable rail trolley and a positioning device placed on it, track measuring equipment for measuring the current track coordinate, rail track width, relative position of the rail threads in height, as well as a system for analyzing track parameters and a data transmission interface through an adapter for communication with an external computer database, according to a new technical solution, equipped with an automatic device for measuring rail bending arrows strands in a horizontal plane and installed on a rail trolley with a software-analytical device consisting of a unit for recording measurement results, a unit for detecting deviations of the path parameters from the set norms, a digital indication unit and graphical visualization of the values of the recorded path parameters during movement in real time directly at the monitoring site indicating the deviations from the set norms and marks of the path faults with the possibility of voice commentary for each mark, as well as loka memory of the results of the measurement of path parameters.

Equipping a removable manual rail trolley with an expanded complex of track measuring equipment with the ability to process and analyze measurement results, as well as digital displays and graphical visualization of the values of recorded path parameters during real-time movement

directly at the place of control, indicating the identified deviations from the set standards and marks of track faults with the possibility of voice commentary for each mark, provides quick detection of violations of the set standards and the adoption of the right emergency decisions to eliminate critical problems, increasing the safety of railway traffic.

The presence of distinctive features in the claimed technical solution allows us to conclude that it meets the condition of patentability “novelty”.

The patentability condition "industrial applicability" is confirmed by the example of a specific implementation.

The essence of the new technical solution is illustrated by the presented images and technical drawings:

figure 2 is a General view of a software-analytical device;

figure 3 is a structural-functional diagram of a measuring complex.

The PT-9 travel measuring system is intended for monitoring, recording and displaying the values of the current track coordinate, rail gauge (gauge) and mutual excess of one rail yarn relative to another (level) during construction, operation and repair work of the railway, as well as visual analysis of recorded data presented in graphical form.

The PT-9 travel measuring system is made in the form of a removable rail trolley, the chassis of which is an all-welded frame 1, supported by four wheels 2, two of which are mounted on a spring-loaded telescopic fork (not visible in Fig. 1), providing constant lateral pressing and contact wheels with rails. The trolley is equipped with a folding handle 3 for controlling the movement of the trolley.

The communication interface 4 of the positioning device 5 of the travel measuring complex provides data transmission from the positioning device 5, equipped with a GPS sensor 6 — a satellite positioning receiver, transmitting synchronizing pulses from the path and speed sensor 7 to the automatic measurement recording unit, i.e. transfer of the current coordinates of the path needed to synchronize the work of the travel measuring complex.

Tracking equipment of the complex is equipped with a sensor of the traveled path 7, a level sensor 8 and a sensor 9 of the track gauge 9. The PT-9 travel measuring complex is also equipped with an automatic device for measuring the bending arrows of 10 rail threads in the horizontal plane.

The sensor of the traveled path 7 is installed on the right front wheel of the trolley. It consists of two adjacent Hall sensors. The sensor gap is blocked by a sector rotating with the wheel. The sensor determines the size and direction of movement of the trolley, and also generates synchronizing pulses for the microprocessor of the software-analytical device 11 with a step of 0.125 m along the coordinate of the path.

On the right rear wheel is a folding latch-latch that stops the rotation of this wheel when the truck is parked on a longitudinal slope of the rail.

To measure the level of rail threads, a pendulum level sensor 8 is placed inside the frame 1, which operates on the principle of a pendulum, tracking the direction of the gravitational vertical in the cross section of the path. The level sensor is fixedly mounted on the frame of the cart. Its output signal is directly proportional to the transverse roll angle of the trolley frame relative to the horizon line. The onboard microprocessor calculates the level value from the measured roll angle of the frame.

To measure the width of the rail track inside the frame of the trolley placed a linear displacement sensor 9. The microprocessor calculates the amount of movement by the number of pulses.

For storing, analyzing and displaying the readings of the measuring sensors, a software-analytical device 11 s is installed on the frame 1 of the rail trolley

a liquid crystal screen 12 and a keyboard panel 13 with which it is controlled.

The software-analytical device 11 has a non-volatile memory, autonomous rechargeable batteries are used to power the electronic equipment.

The program-analytical device 11 located on the railroad car is equipped with a unit for recording measurement results 14, a unit for detecting deviations of the path parameters from the set norms 15, a digital indication and graphic visualization unit 16 values of the recorded path parameters during real-time movement directly at the monitoring site, indicating the identified deviations from the set norms and marks of malfunctions of the path with the possibility of voice commentary for each mark, as well as a memory unit 17 of the results of changes rhenium path parameters.

The automatic registration unit of the measurement results 14 performs in real time the registration of each of the measured parameters of the path synchronized by a single coordinate of the path.

The unit for detecting deviations of the path parameters from the set norms 15 analyzes each of the measured parameters of the path with the regulatory requirements established for this section of the path, and then sends the results of the deviations from the norms to the non-volatile automatic memory block 17 of the program-analytical device 11.

The non-volatile automatic memory unit 17 captures: the results of recording measurements of parameters coming from the automatic recording unit of measurements 14 in real time; pre-established norms of travel measuring parameters; results of determining deviations from normative parameters; parameters of rail infrastructure facilities located in the investigated, controlled area.

The digital indication and graphic visualization unit 16 provides a digital indication and graphic interpretation of the results of processing and analysis of all path parameters on the monitor screen in real time directly on the spot

measurements, including the results of measurements of bending arrows of rail threads in the horizontal plane - straightening, as well as detected path faults, which are noted by voice comments.

The software control device 18 of the software-analytical device 11 enters the initial settings of the track measuring equipment; selection of operating modes of measuring equipment; managing the selection of information from the measurement recording unit 14 and its output to the screen 12 of the visualization device 16; selection of items in the software menu of the software analytical device 11.

The communication interface 19 of the software-analytical device 11 with the measuring equipment provides the transmission of measurement results from the sensor of the traveled path 7, from the sensor of the width 9 of the rail track, from the level sensor 8 of the rail threads, from the sensor of the device for measuring bending arrows 10 of the rail threads in the horizontal plane.

The communication interface 20 of the software-analytical device 11 is used to transfer data via a non-volatile memory unit 17 to the computer of the railway enterprise or to the computer database of the department of railway and railway control structures. The two-way communication interface 20 with an external computer or computer database provides a convenient and universal exchange of measurement results and analysis of path parameters.

Works track measuring complex PT-9 as follows. After the power supply from the autonomous batteries of the program-analytical device 11 is turned on, the microprocessor unit is loaded with initial installation programs to initialize the internal 4, 19 and external 20 interface devices, thereby preparing the program-analytical device 11 for operation. From the software control device 18, initial settings of the track measuring equipment are entered into the microprocessor unit.

Including positioning device 5 in operation, the PT-9 travel measuring complex is “linked” to the location of the monitored section of the track on which measurements are made. All of the above setup and

“Binding” is controlled by the operator of the PT-9 travel measuring complex on screen 12 of the digital display and graphic visualization unit 16. After entering the initial parameters of the controlled area, they are simultaneously monitored and analyzed.

From the moment the PT-9 track measuring complex begins to move from the sensor of the traveled path 7, signals are sent to the microprocessor unit of the software-analytical device 11 through identical segments of the traveled rail track (0.125 m) of the monitored section and synchronization is carried out along the same coordinate of the path of all interface devices - the communication interface with positioning devices 4, with track measuring equipment 19, interface 20 two-way communication of data reception and transmission with an external computer or external computer Zami data.

Through the internal communication interfaces 4, 19, data is transferred between the software-analytical device 11, the positioning device 5 and the measuring sensors 7, 8, 9, 10 of the measuring equipment.

The measurement results, synchronized by a single coordinate of the path, are transmitted to the block for automatic registration of measurements 14, from which they enter the memory block 17.

In the memory block 17 there are also pre-set - given before the passage of the controlled area - data on the norms of the measured parameters.

The operation of the block 15 for detecting deviations of the path parameters from the set norms consists in the fact that a “packed” file is taken from the memory block 17 — the results of measurements of the path parameters collected in a single packet “attached” to a single coordinate of the path — corresponding to a certain coordinate of the path, this, each measurement parameter is numerically compared with its normative value corresponding to this particular coordinate of the path, the comparison result is transmitted to the memory unit 17 and simultaneously enters the digital display unit 16 AI and graphical visualization.

The software control device 18, operating on the instructions of the operator, provides the selection of the required information from the memory unit 17 and output to

screen 12 of the block 16 digital display and graphic visualization. Using the software control device 18, the operating mode of the measuring equipment is selected, as well as the required software menu item is selected.

The results of monitoring and analysis obtained after processing in the microprocessor unit of the software-analytical device 11 can be transmitted by the operator for further processing using the two-way communication interface 20 of data reception and transmission to external computers, which increases the efficiency of using this travel measuring system by making operational decisions on the most important rail maintenance and repair work, thus fulfilling an important role in making responsible strategic decisions in railway traffic.
