For control and correction station 2 (figure 1) antenna 3 are signals from navigation satellites 11-1nfor example , the GLONASS system, which are processed in the navigation receiver 4. Output from the GPS receiver 4, the signals containing information about the numbers of the satellites, the time for receiving the navigation signals, the measured ranges to the respective satellites 11-1n(R1, R2...Rn), arrives at the transmitter amendments 5. From the output of the transmitter parameter 9 in the transmitter amendments 5 enter information about the reference ranges (R'1, R'2...R'n) to the respective satellites 11-1nthat are defined in the solver option 9 on the known coordinates of the control and correction station 2.

T.e. Vc=V1-ΔV. Output offset speed 18 speed information Vcarrives at the first input of the transmitter path 19. To the second input of the transmitter path 19 receives information about the current time t from the GPS receiver 13, the information on the time tcwhen disturbed signals from navigation satellites 11-1n. for example when entering a train in the tunnel, as well as data about the coordinates of the rolling stock 11 for this mo is enta time t c. In the transmitter path 19 to the speed of the rolling stock 11 (Vcfrom block 18 and data about the current time t from block 13 is determined traversed by part of the path from time tcaccording to the formula P=Vc·t. Information about the traversed path P and the coordinates of the rolling stock 11 for time tccomes from the output of the transmitter path 19 to the first input of the transmitter location 20. To the second input of the transmitter location 20 receives data from the memory block path 25. In memory block path 25 stores information about the nature of the railroad tracks, for example, in the tunnel (the radius of curvature, the slope of the path length of the tunnel and so on). In the transmitter location 20 according to information from block 25 and block 19 is determined by the location of rolling stock 11 in the tunnel, the received data is output from the transmitter location 20 in the transmitter 21 of the driving.

From the output of the demodulator 17 in the evaluator of section unit 22 receives the information about the route of the station, namely the number of path and speed of movement. According to information from the output of the demodulator 17, the transmitter 21 of the driving unit memory block 27 in the evaluator of section unit 22 to define what are the parameters of the block and the route of the station. The obtained information is transmitted to the connection unit 23 and then into the management system of the locomotive to indicate to the operator and to control the braking and speed.

Functional diagram of a computing device with software I/o data on RES [7], described in the implementation in microprocessor module 580 IR 80. Structural diagram of a variant of building blocks 5, 9, 14, 18, 19, 20, 21, 22 shown in figure 2, which shows, for example, p is clucene blocks 19 and 25 to the inputs of the block 20. The decoder 28 provides a choice of DC 29 or 30 operational storage device in which programs, constants, or current information, respectively. Microprocessor module 31 performs the processing and exchange of information in accordance with the flowchart (figure 3) and is associated with blocks 28-30 address bus (SHA) and blocks 29, 30, 32, 33 information system data bus (SM), can have control outputs with signals "read" and "write" to control a constant 29 and 30 operational storage devices, respectively, output - for example, to display information on the SM bus from the block 20 block 21, the input "interrupt request" and enter the bus in SM the block 20 from block 19. The signal handling (input) from external blocks 19, 25 to computing device 20 is formed by decoding the code address of the corresponding register in the decoder 34 and the conjunction of its input signal "input" elements And 35-36. Output signals of the elements And 35-36 recording information from external blocks 19, 25 in the registers 32, 33. When implementing blocks 5, 9, 14, 18, 19, 20, 21, 22 on the basis of the microprocessor To 580 microprocessor module 31 consists of three large-scale integrated circuits (LSI) - CPU CIC, the system controller CVC, clock generator KGF. Navigation receivers 4, 13 can be made in accordance with the laws the AI with (figure 1.14) [5], 38 [6], RES [3], RES, 14.7, 14.8 [8]. The implementation of individual units, located on the control-adjustment unit 2 and the movable part 11, as described, for example in[5, 6, 7]. Thus, we can conclude that the use of the claimed control system location of rolling stock increases the safety of trains due to the automatic determination of parameters of the driving, the block section and the traffic of the station, namely the number of path and speed of movement. Also reduces costs associated with maintenance of the control system location of rolling stock due to the exclusion of the base floor devices and reduce errors in the determination of the location of rolling stock, which is less than 1 m [3].
