A well-known automated optical-electronic system for reading the numbers of cars of rolling stock of railway vehicles "ARSCIS" (Malygin L.L., Moshnikov V.V., Tsarev V.A. Optoelectronic system for identifying objects of rolling stock ARSCIS at the station Cherepovets of the Northern Railway / Report collection scientific-practical conference "Innovative projects, new technologies and inventions." - October 27-28, 2005, the Experimental ring of VNIIZhT. - M .: VGUP VNIIZHT. S.122-130.). This system is intended for recognition, registration (reading) and automatic verification according to the nature list of identification numbers of freight cars of rolling stock of railway transport. The system consists of an optoelectronic subsystem for collecting information, illumination sources of the control area, to ensure round-the-clock operation of the optical subsystem, induction sensors that fix the position of the wheelsets and the computational subsystem used to process the received data.

The disadvantage of this system is the low reliability of recognition of wagon numbers in conditions of contamination of the numbers of numbers.

The known system of automatic identification of vehicles "Palm", based on the principles of microwave technology (Belov V.V., Buyanov V.A., Rabinovich M.D., Dudkin V.F., Milgotin B.V., Easy N. M., Kotletsov D.S. "Palm" - automatic vehicle identification system /

Railway transport. - No. 8, 2002. P.54-59.). This system is designed to automatically record the time of the investigation and identification of railway rolling stock.

The disadvantage of this system is the low reliability of the identification of units of railway rolling stock in case of failure of the on-board encoder sensor, the probability of which is high during loading and unloading, as well as in cases of vandalism.

The closest to the proposed device, in technical design, is a device for automatic identification of units of rolling stock, which is part of the multifunctional complex of technical means (KTSM) (Shvalov D.V., Shapovalov V.V. Diagnostic systems of rolling stock: Textbook for technical schools and colleges railway transport / Under the editorship of D.V. Shvalov. - M.: Route, 2005 .-- 268 p.).

The device consists of an overlay rail circuit connected to a rail shaper block, the output of which is connected to the first input of the discrete signal processing block, induction wheel passage sensors, connected respectively to the inputs of the axle sensor shaper block, the outputs of which are in turn connected to the block inputs processing of discrete signals, the data switching unit to the first and second inputs of which the first and second outputs of the discrete signal processing unit and the display device are connected I have information connected to the output of a data switching unit.

The disadvantages of this device are the low reliability of identification of units of railway rolling stock and limited functionality, manifested in the identification of only the class of units of rolling stock.

This technical solution is selected by the author as a prototype.

The technical result is to expand the functionality of the device and increase the reliability of identification of units of rolling stock by measuring all the distances between the axles of the wheelsets and calculating based on their values of the overall lengths along the axes of the automatic coupling of the units of the rolling stock.

The technical result is achieved by the fact that in a device consisting of an overlay rail circuit connected to a rail shaper block, a discrete signal processing block, the first input of which is connected to the output of the rail shaper block, two inductive wheel pair passage sensors connected respectively to the first and second the inputs of the axial encoder driver unit, the two outputs of which are connected respectively to the second and third inputs of the discrete signal processing unit, the data switching unit, the second and second inputs of which are connected respectively to the first and second outputs of the discrete signal processing unit and the information display unit, the input of which is connected to the output of the data switching unit, an additional block of counters is added that records the switching unit, the unit type calculation unit of the rolling stock, the unit type display unit rolling stock and a rectangular pulse generator, and its input is connected to the output of the rail shaper block, and the output is with the first input of the counter block, the second input is cat It is connected to the output of the rail shaper block, the first and second outputs of the axis shaper block are connected respectively to the third and fourth inputs of the counter block, all outputs of which are connected to the recording switching block, the first and second outputs of which are connected respectively to the first and second inputs of the calculation block type of rolling stock unit, the third input of which is connected to the first output of the discrete signal processing unit, and the output of the calculation unit of the type of rolling stock unit is connected n with type display unit

units of rolling stock, and the third output of the recording switching unit is connected to the fifth input of the counter block.
