The invention relates to railway transport and provides increased speed train crews when searching for a vehicle with a broken lower envelope.

Known monitoring device Assembly of the rolling stock (OXPS) (patent RF №2279369, B61L 23/26, 2006), controlling the lower envelope of mobile units and provide information about the violation of the envelope, including the derailment of the unit from the rail. The device is a jumper and a cross member mounted on railroad tracks, the integrity of which is broken under the action of oversized elements movable unit. Information about the breach goes to the control room. Search for oversized units is the locomotive crew. But the system has low efficiency because the sensor does not provide information about the index number of the car and its General form, and therefore the inspection of cars takes a long time. In addition, there are situations triggered UXES for any other reasons not related to the passage of the train, then the situation becomes uncertain, requiring additional review and determine the cause of the sensor.

Known systems account of wheelset axles. But these systems do not allow to identify the mobile unit with the violation of the lower envelope and the E. provide information about the General views held mobile units. In addition, the systems require the installation of at least two wheel sensors spaced at large distances (for example, the semi-automatic block system with sensors DPAP-M CJSC "WNTC "Uralzheldoravtomatizatsiya". Cm. journal of Industrial transport of the Urals" No. 9, 2007, p.30.

Also known ways of identifying mobile units train, based on the radiation signal passive tags installed on the unit, and fixing the reflected wave (for example, U.S. patent No. 4739328). But these systems are complex in construction and require labels on all existing and newly manufactured mobile units.

There is a method of surveillance for a train (application No. 95113376 from 28.07.1995, the patent of the Russian Federation), but this method is not possible with enough reliability to detect the sliding unit with the broken lower envelope.

To the greatest extent the proposed solution corresponds to the device that implements the method of identifying mobile units of railway transport (patent RF №2280580, B61L 25/02, 2006), which uses two wheel travel sensor located at a fixed distance from each other less than the minimum distance between the inner wheel pairs of the movable unit, the timer time stamp that bind a temporary system, the reference is to the moving part. In the operation of the system are determined by the center distances of the mobile units, which are compared with the data on the structure of the inter-axle distance wheel pairs, pre-stored in the memory of the hardware.

The task on which the present invention is directed, is to increase the efficiency of the search of a vehicle with a broken lower envelope, raising awareness of data on the mobile unit.

This objective is achieved in that the control device derailment of rolling stock that contains jumpers and sleepers installed on the path and controlling the lower envelope of the composition, track sensor, timer, digital video recorder provided with a counter-deciding device having the opportunity to provide information on the means of communication with the dispatching, according to the invention the travel sensor is installed on a structurally minimal possible distance from jumpers and crossbars, and the DVR is set at the distance and angle from jumpers and cross-beams, which in his account is possible with the naked eye the type definition of mobile units and the places of their oversize precision sufficient for rapid retrieval, in addition, the device is equipped with a timer time of receipt of signals passing wheelsets n the d travel sensor, reported path sensor, calculating a critical device and a timer, and the timer labels provided with a path sensor, DVR and counting is a crucial device for applying labels oversized movable unit in the memory of the counting-casting device and the materials surveillance, and the identification algorithm of mobile units calculating a crucial device using a data definition has an opportunity to consider the dynamic characteristics and, for example, four-axle wagon is based on the formula

where S is the distance between first and last axle of a carriage;

s1- the distance between the axes of the first cart;

t1- the time interval passing over the pedal first and second axes of the first cart;

t2- the time interval passing over the pedal first and second axes of the second truck;

T - the time of passing over the pedal bearing platform of the carriage defined by the difference of the current time since the passage of the first axis and the last;

- the speed of the motion on the pedal at the time of passage of the first trolley car;

- the speed of the motion on the pedal at the time of the passing of the last truck of the car.

Distinctive features of the proposed technical solution p is compared to the same are:

- installation in close proximity to each other, the sensor control device derailment of rolling stock, track sensor and video surveillance equipment;

- introduction to the special timer connected to the timer, allows you to measure and make a mark moments of the travel time on path sensor wheel pairs, as in the prototype are measured intervals passing the known distance of wheel pairs;

- the introduction of a timer that makes a mark in the mobile unit with the broken dimensions in the counter-casting device, materials surveillance.

- security alarm dispatch center about the number of mobile units with broken dimensions.

Provides enhanced information content, because in addition to center distances that are used in the prototype to identify units in the device identification is made according to the ratio of the interaxial distance of the mobile unit, and in addition, are defined and used in the identification of dynamic parameters of units. Also, in further development can be considered the ratio between the coupling of the mobile units and the stiffness of the springs themselves hitches.

The invention is illustrated in the drawing, in which figure 1 presents the monitoring device Assembly of rolling stock (structural scheme is (a), figure 2 - histogram of the distribution of the values of the experimental data to the base.

Jumpers and cross-beams 1 are set on the path 9 and control the lower envelope of the structure, including the gathering of mobile units. Track sensor 2 is installed at a minimum distance from jumpers and cross-beams 1, which allowed constructively in each case. This arrangement provides the most accurate identification oversized movable unit. Video 3 is located away from the track 9 on the distance and angle at which his account is possible with the naked eye the type definition of mobile units and noted places of oversize with sufficient accuracy to its fastest search locomotive crew. The placement of the timer 4, the counting-casting device 5, timer 6 and 7, the device communication with the dispatching 8 arbitrarily and is not essential to solving the problem of the invention. The only limiting factor here is the reliability of the data collection and transmission of signals via communication lines.

Jumpers and cross member 1 is electrically connected and communicated with the accounts-critical device 5, which commits them to fire. DVR 3 communicated with the timer for applying labels in the materials videonabludenie who I am 7. The timer associated with the timer times 6. Track sensor 2 is in communication with both the timer 6 and 7, which may be located inside the counting-casting devices, and beyond. In the second case, the connection between the timer and counting-critical device is saved. The timer can also be an integral part of the accounts-casting device.

It is also possible floatation devices 4-7 comprising computer directly to the workplace of the Manager; or complete the transfer functions of these devices on hardware and software capabilities of the computer.

The operation of the control Assembly of the rolling stock is as follows.

In the immediate vicinity of bridges and cross devices are installed track sensor 2 and videoregistrator 3 connected to the counting-critical device 5. In calculating the deciding device, set the timer time of the passage of wheelset axles over travel sensor 6 and the timer for applying labels oversized movable unit in the materials surveillance, memory counting-casting device and alarm on the remote controller 7.

During the passage of rolling stock over the device trips the travel sensor, sending a signal to the counting-solver, where using the timer time is registered in the memory in accordance with the interval of the mi time of their receipt.

At the same time being mobile video units train.

Counting-critical device 5 using the time intervals between receipt of signals, starting with interval passing the first two wheelsets, finds correlations between them. For example, the ratio of the time interval between the first two wheel pairs and the time interval between the first wheel pair and a third. In uniform motion, this ratio is ideally equal to the ratio of the respective distances between the wheel pairs.

For example, for a four-axle wagon is true:

,

where t is the time interval passing over the pedal two axes truck;

T - time interval passing over the second pedal axis of the first truck and the first axle of the second truck;

l, L - relevant geometrical dimensions of four-axle wagon.

Correlations are compared with the ratios of the distances between the wheel pairs of mobile units available in the counter-casting unit. Based on the results of the comparison identifies the mobile units and the conclusion is made about the type of locomotives and rolling stock cars and General cargo or passenger locomotive and its type; passenger or freight wagon, open wagon, covered wagon, truck, platform, qi is the turn and the information is transmitted to the remote controller.

In the Appendix (table 1) shows the ratio for locomotives. In table 2 are the distances for freight cars (See. "Freight cars of 1520 mm gauge Railways of the USSR." Moscow: Transport. 1989. Reference album.) The analysis shows that the ratio is uniquely determined by the type of locomotive and hence its geometrical dimensions and the distance between the wheel pairs trucks. Using the axle spacing of the trucks of the locomotive, it is easy to determine the speed of the motion, and therefore the distance between axes of the first trolley cars. When determining the type of locomotive is possible to use data annotation locomotives to the depot.

For uniformly accelerated motion must take into account the change in velocity over time. In the calculation it is assumed each mobile unit has a constant average speed.

The equation of uniformly accelerated motion for the case of its application to the estimation of the length of the axle of a railroad car representable

where S is the distance between first and last axle of a carriage;

s1- the distance between the axes of the first cart;

t1- the time interval passing over the pedal first and second axes of the first cart;

t2- the time interval passing over the pedal first and second axes of the second truck;

T - in EMA passing over the pedal bearing platform of the car, defined by the difference of the current time since the passage of the first axis and the last;

- the speed of the motion on the pedal at the time of passage of the first trolley car;

- the speed of the motion on the pedal at the time of the passing of the last truck of the car.

For more information about the components of the rolling stock units allow you to get the video.

When the violation of the lower envelope of the mobile unit actuates the control device Assembly of the rolling stock. The signal fed into the counting-solver, where the timer emits a movable unit with impaired clearance, and control point receives information about the operation of the monitoring device Assembly of the rolling stock, the sequence number of the mobile unit, starting with the locomotive, its most likely the type and General appearance, as well as videos with a mark in the mobile unit with impaired clearance. This information is immediately transmitted train crew, which purposefully and quickly searches for faults in the structure and solution.

Testing methods for identifying mobile units train was held at the South Ural railway. On the railroad tracks was established track datix floor signal Converter. The signals were recorded and displayed on the computer. The time between the signals was measured with an accuracy of 0.002 sec. Figure 2 gives the histogram of the distribution of the values of the experimental data to the base for cars. When the alignment Normal to the law of variance was 0,000009.

In Annex table 3 shows the results of the experiment. As a result of comparison of experimental data the value of L is computed length of the car with the basic data of tables 1 and 2 were identified locomotives VL-10 and, basically, open wagons and four tanks.

The dimension between the axes of the wheel pairs of the most common models of two-axle freight trucks is 1850 mm
