A device is known (RU 2120866, IPC V60M 1/12, V60M 1/13, B60L 3/12. V.A. Arsenyev, V.P. Gerasimov, S.S. Repin. Device for measuring and recording wear of a contact wire. - Publ. 27.10.1998), including television cameras, illuminators, photodetectors, processing unit and information display.

The disadvantage of this device is the use of complex and expensive equipment.

The closest in technical essence to the proposed device is a system (Pronchenko R.S. The system for processing and analyzing images of the contact network of railway transport according to scanner data [text]: dis. ... Candidate of Technical Sciences: 05.13.01, protected on 23.09.2009 - Ryazan, 2009), which includes a filming complex containing an optical system with N CCD arrays mounted on the roof of a laboratory car, and an information processing and storage unit.

The disadvantage of this system is the complexity of the equipment that is installed on the roof of the laboratory car, moving exclusively along the main tracks of stations and railway lines.

The aim of the invention is to simplify the equipment used, increase the mobility of the device and expand the zone of automated control of wear of contact wires.

This goal is achieved by using available components, the measuring head is compact and easily tuned to the operating state, the device allows measurements to be made on any part of the path.

The essence of the invention lies in the fact that the filming system is placed on a movable insulating removable tower, consisting of a frame with wheels, on which an insulating part with a carriage is installed, in which a battery and a control unit are placed, and a distance monitoring sensor connected with the control unit via a wireless channel, traction springs made of dielectric material are pivotally attached to the carriage, other ends are also pivotally connected to the cartridge, in which A spring-loaded rod with a measuring head is located inside the hollow body of which are two horizontal cylindrical rollers located parallel to each other and perpendicular to the longitudinal axis of the measuring head housing at its opposite ends, between them on both sides of the longitudinal axis of the housing are placed three pairs of vertical cylindrical hollow conical top rollers equipped with springs, elastically moving perpendicular to the longitudinal axis of the hollow body under the action of the springs, and the optical The system is a scanning element consisting of a light-emitting module, lenses and one CCD line, rigidly attached to the lower edge of the hollow body perpendicular to its longitudinal axis, and the control unit is equipped with a keyboard and a connector for connecting a removable USB-Flash drive, which receives information from scanning element and from the sensor monitoring the distance traveled, and the power supply of the shooting complex is carried out from the battery located in the carriage.

Figure 1 shows a diagram of a General view of a device for determining the wear of a contact wire mounted on a movable insulating removable tower, consisting of a frame with wheels 1, an insulating part 2 and a carriage 3, in which the batteries and the control unit (not shown) are placed. On the frame 1 there is a sensor for monitoring the traveled distance 24, the data from which is transmitted to the control unit (not shown) via a wireless channel, and to the carriage 3 are pivotally attached with spring 4 rods 5, the other end is also pivotally connected to the cartridge 6, in which the spring loaded the rod 7 of the measuring head 8 and to which a nylon cable 10 is attached through an insulator 9.

Figure 2 presents a section (top view) of the measuring head 8, including a hollow body 11, horizontal rollers 12, vertical hollow rollers 13, springs 14, scanning element 15, contact wire 16.

Figure 3 presents a section (front view) of the measuring head 8, mounted on a rod 7 mounted in the cartridge 6 on the spring 17.

Figure 4 shows the principle of operation of the scanning element 15, and figure 5 shows the image of the contact wire 16 obtained using the scanning element 15. The light-emitting module 18 of the scanning element 15 generates a light flux 19, which, falling on the lower (worn) surface of the contact the wire 16 is reflected from it, and through the lenses 20 it falls onto the photodetectors 21, as a result of which a bright region 22 is formed on the scanned image. When the light stream 19 gets onto the side edges of the contact wire 16, the photodetector the detectors 21 are not fixed, and a dark region 23 is formed on the image.

The present invention works as follows.

The brigade of the contact network area, consisting of the manufacturer of the work, the operator and 4 members of the brigade, puts on the railway track an insulating removable tower with a pre-installed shooting complex (Fig. 1), including traction 5 with a spring 4, a measuring head 8 with a rod 7, installed in the cartridge 6, the sensor monitoring the distance 24, the battery and the control unit (not shown). At the same time, the rope 10, attached through the insulator 9 to the cartridge 6, is fixed to the frame 1 of the insulating removable tower (Fig. 1) so that the rods 5 are in the lowest position, which ensures the safety of the team members during preparatory work, eliminating the possibility of touching parts filming complex of contact network devices.

After installing an insulating removable tower on the railway track, the operator rises into the carriage 3, for security reasons, installs a shunt rod (not shown) on the contact wire 16, turns on the autonomous power supply from the battery, and, using the keyboard of the control unit (not shown), enters into it information about the date of the measurements, the kilometer and the picket of the start of measurements, the number of the anchor section. Then the operator removes the shunting rod (not shown) from the contact wire 16 and descends onto the railway track, after which it unfastens the rope 10 from the frame 1. The force of the spring 4 ensures the lifting rods 5 with the measuring head 8 to the contact wire 16, therefore, the operator using the rope 10 attached through an insulator 9 to the cartridge 6, must control the process of lifting rods 5, ensuring a smooth approach of the measuring head 8 to the contact wire 16 and its installation in the working position. After that, on the team of the foreman, the team members move the insulating removable tower along the railway line.

The sensor for monitoring the distance traveled 24 is turned on at the beginning of the movement of the insulating removable tower (Fig. 1) and records the distance traveled, and rods 5 pivotally attached to the carriage 3 and the springs 4 and 17 provide continuous sliding of the measuring head 8 along the contact wire 16 when changing it position in space.

When the filming complex (Fig. 1) moves, the scanning element 15 (Figs. 2, 3) takes a contact wire 16. In this case, the horizontal rollers 12 (Figs. 2, 3) located in the measuring head 8 continuously maintain this distance from the scanning element 15 to the contact wire 16, which is necessary to obtain a high-quality image (Fig. 5), and the spring-loaded vertical rollers 13 (Fig. 2, 3) provide unhindered passage of the terminals mounted on the contact wire by the measuring head 8 (Fig. 1).

The information received from the scanning element 15 (Fig.2, 3) is transmitted to the control unit (not shown) in the image format and is combined with the data transmitted via a wireless communication channel from the distance monitoring sensor (not shown). Thus, the scanned image of the contact wire (Fig. 5) is saved only when the insulating removable tower (Fig. 1) is moved. This approach allows, firstly, to avoid saving unwanted information obtained during the period when the insulating removable tower (Fig. 1) does not move or is removed from the railway track to pass the train, and secondly, to save the image of the contact wire with reference to a specific section of the path.

After completing the measurements, the operator, using the rope 10 attached through the insulator 9 to the cartridge 6, lowers the rods 5 with the measuring head 8 and fixes them in the lower position by fixing the lower end of the rope to the frame 1 of the insulating removable tower (Fig. 1). After that, the tower is removed from the railway track.

Information stored in the control unit in the form of images, at the end of the measurement session using a removable USB-Flash drive is transferred to a personal computer on which special software is installed.

In the scanned image (figure 5), the worn surface of the contact wire 16 is determined by the photodetectors 21 as the bright area 22, and the side faces of the contact wire 16 as the dark area 23.

The image processing algorithms used in the special software are based on the segmentation of the image into sections one pixel wide and allow us to calculate the width of the wear pad of the contact wire by distinguishing between dark and light pixels in each such segment, and then get the value from the width of the wear pad of the contact wire its residual height. The image processing results are displayed as a graph of the dependence of the residual height of the contact wire on the length of the anchor section.

Thus, the proposed device has a simpler design, does not require the use of expensive equipment, does not occupy the railway line, as it is easily removed and mounted on rails, thereby expanding the zone of automated control of wear of contact wires.
