The higher the speed of the car, the greater the air pressure, and therefore a threat to the environment, resulting in lower reliability of the control system.

In addition, the method of the chord does not provide high precision control when the vibrations of the car, the bottom of which is fixed the emitters and the receiver. Even small amplitude of vibration emitters and receivers will cause defocusing of the beams in the control zone on the rail. The degree of deviation of the radiating and the reflected light fluxes from the vibration of the transmitter and receiver will depend on their distance from the controlled zone, and the greater this distance, the lower the accuracy of the control.

The detector 4 is provided is Savasana anomalies such as voids, boxes, bags, ice lenses, etc.

The detector 4 is made in the form of GPR 8 with transmitting and receiving antennas 9 and 10 and the computer 11 connected to the output of the GPR 8. Antenna 9 and 10 (Fig. 3) is placed on the outer end of the carriage 1 on opposite sides of the vertical axis of symmetry of the face and can be rotated in the plane of the cross-section of the carriage 1 by an angle the value of which provides the sensing antennas 9 and 10 of the subgrade in the plane of the cross-section of the carriage 1 at a depth of 6-10 m from the running surface of the rails.

The 12 meter speed and traveled distance is made in the form of two Autonomous, for example, eddy current counter rail joints installed above the rolling surface of one of the rail lines and spaced apart from each other along the thread at a fixed distance. Meter 13 elevation and slope and the meter 14 radius curve of rotation of the path and position of rail lines on the level is based on, for example, accelerometers and installed in the cabin of the car 1, oriented with their sensitive axes, respectively, the meter 13 vertically, and the probe 14 along the line of intersection of horizonto vertically up and down, the meter 14 measures the tangential acceleration of the car 1 on curved sections of the path and the angle of the carriage 1 in the cross section of the path. Blocks sensors 15 and 16 mounted on the unsprung frame 2 is rigidly and installed properly to one and the other surfaces of the ski design position of the yarn path and away from the axis of the wheelset at a distance not less than half the diameter of the wheels of the carriage 1, is necessary to enable fastening of the blocks of the sensors 15 and 16 on the frame 2 (Fig. 1).

The meter 12 and the sensors 15 and 16 from the side of the sensing element is protected by lids (Fig. not shown) of a dielectric material. The pyrometer 20 is installed on one of the thread path and represents, for example, a temperature meter with a sensor element that converts thermal infrared light rail into an electric signal.

Shutter 44 provide protection optical sensor elements 25 and 26 and the chambers 28 and 29 from exposure to surround what may be done, for example, from polyester material. In addition, the second and third chambers 28 and 29 are equipped with temperature-controlled boxes 46 to maintain the temperature of the chambers 28 and 29 constant. Turrets 38-43, electric shutters 44 and the temperature-controlled boxes 46 are controlled by commands computing center (EVC) 7 with consideration given to EVC 7 software, and turns and move the turret 38-43 via the pointing device (Fig. not shown). The inclusion of sensors 25 and 26, the second and third chambers 28 and 29 are programmable from EVC 7 through switches 23 and 24 depending on the direction of movement of the carriage 1 without its spread. The first chamber 27 runs continuously regardless of the direction of movement of the carriage 1. When the movement of the carriage 1 to the left (Fig. 4) operate the sensor 25 or 26, depending on which side of the car 1 are contact network, the first 27 and 29 third camera, the motion of the carriage 1 to the right are the sensor 25 or 26, the first 27 and second 28 of the camera. Installation directions for sensors 25 and 26, and the second and third chambers 28 and 29 are opposite directions. When getting into the field of view of the sensor 25 or 26 contact network in the analyzing unit 22 subsystem technical Serena chamber 34 with the lens (Fig. 5) made in the form of platform 46, which is hosting tural 43, two channel 47 defined them in the guide bushings 48. Channel 47 with inserts 48 are placed along the longitudinal axis of the carriage 1 in tower 3. The platform 46 is based on the guide bushings 48 and moves over them. To reduce friction liners 48 are made, for example, PTFE.

Control quality of porcelain insulators and electrical connections of the contact network is carried out by the visual method on the screen of the device 35. Defective insulators (chips, cracks, etc. and poor contact electrical connections are characterized by scattering them a large electric power, which leads to heating of the controlled objects. On the screen of the device 35 they are observed as bright images or spots, which is a criterion for rejection.

EVC 7 is designed for recording, processing, storing and providing information received from the subsystem vision system 6, as well as call and display any information from computing machines 11 and 21. EVC 7 consists of a Central interface (Fig. 2 is not shown), the computing machine 49, monitor 50 and software. Program data on controlled objects, and items of railway equipment. The first local ASCS, attached to an automatic data processing machine 11, contains information about the structure of the soil subgrade and education in its anomalies, the second local ASCS, attached to the machine 21, the data on monitored parameters superstructure, Central ASCS given EVC 7, data on the contact network. For example, in the Central ASCS are recorded and stored data about the objects that are subject to control their position relative to the supports, the linear dimensions of the contact of the suspension, the mutual position of the elements of these objects. In addition, the Central ISS provides access to information computing machines 11 and 21, the call and display the required data by the user (operator), replenishment of data about the current state of the controlled object by automatically measuring the linear dimensions between points and lines on images of objects in the image plane of the chambers 27, 28 and 29 and conversion of these data in absolute dimensions, taking into account the information about the mutual position of the chambers 27, 28 and 29 and objects of control.

As computers 11, 21 and 49 of the complex, it is recommended to use the on-Board computers that can withstand overload decomplex. The complex is served by five operators: one flaw detector 4; two multiparameter instrument 5; two - system 6-surveillance technical contact state network with EVC 7.

The technical result of the invention is the provision of safety of railway transportation, which is achieved by equipping the set of additional means of information, links, form complete and rational arrangement in place to allow for laboratory operation in extreme temperature and weather conditions.

The control computer diagnostic complex include in the network 220, for 20 min to warm up, and then the operators configure nodes, sensors and systems in the nominal mode.

The effect of the flaw detector 4 based on the radar principle. The probing signal nanosecond duration is radiated by the antenna 9 in subsurface space subgrade. From the environment boundaries and the boundaries of its own heterogeneity of the environment of the probe signal is reflected in the opposite direction, is received by the antenna 10, is converted in the GPR 8 and processed in an automatic data processing machine 11 with a view Informatica paintings. Boundary line of the paintings displayed on the monitor screen of the machine 11 with dark lines, contours, and the heterogeneity of the actual media blackout different color contrast, the degree of which depends on the electrical properties of the structure of the soil (stone, sand, clay, peat and other). The difference contrast areas, their size and the dark lines are judged on the structure of the soil subgrade, the presence of foreign sites (defects) with their linear dimensions, and the arrival time of a corresponding echo signal is judged on the depth of the defect. The process of sensing roadbed continuous. The received information is recorded on magnetic media machine 11 and is transferred periodically in EVC 7 at his request. Data based contrast from the electrophysical properties of the used soils for railroad tracks stored in the memory of the machine 11.

Information from the meters 12, 13 and 14 blocks of the sensors 15 and 16, the second adder 19 and the pyrometer 20 is fed into the computer 21 in the form of voltages continuously. On known data about a fixed distance between counters butt joints of the meter 12 and the time taken from the timer of the machine 21, the passage of these counters one and t time, for example, 10 seconds, is determined by the distance to the next is the speed at the current time.

When the movement of the carriage 1 along a curved section of track at the exit of the meter 13 will form a voltage proportional to the rise (slope) of the path, and the output of the meter 14 voltage proportional to the curve radius of rotation of the path and position of rail lines by the level in the cross section of the path. The actual values of the measured values are evaluated in the car 21 taking into account the current values of time and the speed of the car 1, taken respectively from the timer of the machine 21 and the meter 12. Depending on the signs of the actual values of the measured parameters is judged on the elevation or slope of the path, right or left) of the radius of the curve of the turning path, the relative elevation in the level of the left or right threads.

In the case of deviations of the real state of the track from the design position blocks the sensors 15 and 16 produce voltages proportional respectively to the deviation of rail lines in plan and profile, the value of clearances in the joints of rail lines and wear the inner side surface of the rail heads and short irregularities, and the output of the second adder 19 poluchaeetsa, obtained from outputs of blocks of the sensors 15 and 16 and the adder 19 are defined in the machine 21. The value of clearances in the joints of rails calculated linear thermal expansion (contraction) of the material of the rails, the value of which is calculated in the machine 21 according to the indications of thermometer 20 and coefficient of thermal expansion of the material of the rails, put into the machine memory 21. The frequency of measurement of each parameter equipment 5 except for the speed of the car 1, and they traversed the distance is 60 1/s At the operating speed of the car 1 is equal to 150 km/h, the measurement along the length of the path will be 700 mm. Computing machine 21 is continuously recording the results of measurement of the control apparatus 5 on the magnetic media.

In addition, the Central ISS provides search and access to all of the visual data also on VHS video recorders 30 and 31 in the stationary mode of processing all the information and display all data received from the TV camera 27, 28 and 29 of videos and images on the screens 32 and 33 and the monitor 50 EVC 7.

Control quality of porcelain insulators and electrical connections catenary hanger is carried out visually on the screen of the third visual display apparatus 35 are independent of other systems and mechanisms of the complex. Moving the platform 46 with the turret 43 along the guide bushings 48 along the viewing tower 3 and adjusting the position of the turret 43, on which is placed the camera 34 with the lens, get a hit of the controlled object in the field of view of the camera lens 34. If the screen of the device 35 will not nabludat the bright image or spots the controlled object is defective.
