Description

A device for sensing a railway embankment as a part of the equipment of the track gauge car belongs to the technique of railway transport and is intended for operational control of the railway embankment during the movement of the car - track gauge.

Known radars (radars) for sensing land, water, walls of buildings, etc. (Hence the most common name is GPR. See http://en.wikipedia.org/wiki/%D0%93%D0%B5%D0%BE%D1%80%D0%B0%D0%B4%D0%B0 % D1% 80).

There are proposals to use a georadar for sensing a railway embankment (see the advertising material “Exploration Presentation of the project for JSC Russian Railways. © LLC Exploration 2010, Moscow).

With all the advantages of the presented georadars, they are intended only to demonstrate their known capabilities on the railways.

The closest in technical essence and the achieved result is a device for sensing a railway embankment as part of a computerized car - laboratory KVL-P2.1 (hereinafter referred to as the track car), including a series antenna assembly containing antenna radar units mounted across the track car, sounding information recording equipment and automated measuring and information system. This known device is taken as a prototype.

For all the advantages of this device, it should be noted its drawback - limited technical capabilities, in particular: fixed sounding depth and resolution of ground penetrating radars when probing a railway embankment.

The technical result, the achievement of which the creation of the proposed device is aimed, is to expand its technical capabilities by introducing additional georadars into it located along the track gauge car.

The technical result is achieved by the fact that in a device for sensing a railway embankment as part of a track car, comprising a series-connected antenna assembly containing antenna blocks of georadars installed across the car - track gauge, equipment for recording sounding information and an automated measuring and information system, moreover, in its antenna assembly introduced the georadar antenna blocks located along the track measuring car.

The figure shows a conditional image of "Device for sensing a railway embankment" (hereinafter, the use of the term "device" is possible) as part of a railroad car.

To simplify the graphics of the figure, the supporting basis of the device — the track car — is not conventionally shown.

The figure shows the axis aa directed along the track gauge car and the axis bb directed across the track gauge ..

The structure of the device includes antenna assembly 1 connected in series with information exchange buses with antenna units 2 ... 6, sounding information recording equipment 7 and an automated measuring and information system 8.

Axes A-A and B-B are the geometric locations of the antenna units 2 ... 4 and antenna units 3, 5, 6, respectively. The antenna assembly 1 is located on the underbody of the tracker so that the antenna units 2 ... 6 are directed towards the railway the embankment.

Each antenna unit includes the antenna itself, a receiver, a transmitter, and a device for primary filtering of useful signals (not shown in the figure). The resolution and the sounding depth of the railway embankment depend on the width of the spectrum of the radio frequencies emitted by the antenna unit.

A device for sensing a railway embankment operates as follows.

During the movement of the tracker car, the antenna units 2 ... 6 probe the railway embankment with the pulses of electromagnetic waves, process the received reflected signals, extracting target information from them. This information reflects the boundaries of the sections of layers and possible foreign objects of the railway embankment having various electrophysical properties; it enters the equipment for recording sensing information 7 and then to the automated measuring and information system 8 for subsequent processing, storage, and intended use. The automated measuring and information system 8 in particular provides synchronization of the operation of antenna units 2 ... 6 of the antenna assembly 1.

Using antenna blocks 2 ... 4, a railway embankment is probed in three zones of the cross-section of the track (field, inter-blast, inside the track). The information obtained characterizes the quantitative and qualitative composition of the materials of the railway embankment, which determines the stability of the position of the rail track. Transmitters and receivers of antenna units 2 ... 4 operate in the same modes.

With the help of antenna units 5, 6, a railway embankment is probed in a wider range of depths (determined by the choice of operating modes of transmitters and receivers of antenna units), for example, to obtain a higher resolution at shallow depths and a greater sounding depth, for example, up to the base of a railway embankment. In this case, the presence of potentially destabilizing factors is determined, in particular, dips, cracks, quicksand, water flows, etc. in order to predict the reliability and durability of the railway embankment.

Thus, the introduction of additional antenna units into the device for sensing a railway embankment significantly increases its information content, which makes it possible to more reliably control the railway embankment and, thereby, increase the safety of train traffic.
