Description

unused with other informational input- 45 electric locomotives. Commands to these blocks are supported by the command memory block. The second input of the element OR 6 is connected to the output of the automaton 8 synchronization, and the output to the information input of the block 12 and to the input of the execution unit 15 0 W-j CQ swarm the input of the automatic machine 8 synchronization is connected to the control output of the execution unit 15.

The synchronization machine 8 contains

step from the output of the command device 3 through the elements OR 5 and 60 All control commands are also sent to memory block 12, and from its output - to the input of the encoder 14 "In memory block 12, the number of memory elements equals the number of control commands sent to its information inputs from the outputs of the elements OR, and commands sig

memory register 16, whose input is the input received from the control

the outputs of the execution units 11 and 15. The memory unit 12 can operate in read mode and write mode. In the recording mode, the signals from it are separated from the output of block 4, and the memory register 17, the input of which is connected to the control output of the execution unit 15. The output of memory register 16

the passage passes to the input of the encoder 14. The transfer of the block 12 to the readout mode is carried out under the influence of the second controller on its control input.

When the memory unit is switched to the read mode, information about the state of the commands that was up to the moment of switching is saved at its outputs. The encoder converts the parallel code into serial code and transmits it to the communication line. On the slave locomotive 2, this code is fed to the input of the decoder 9 and one of the inputs of the control unit 10 The decoder receives information in a serial code that converts to parallel. block 7 alarm. The latter is intended for visual monitoring of the state of the slave locomotive 2 control devices. On the lead locomotive 1, the signal from the output of block 4 to the OR 5 element and the input of the automatic synchronization device 8 is not applied; and the encoder 14 on the lead locomotive 1 — encoding and transmitting to the first communication line information on the state of the command unit and control devices of this locomotive. On the slave locomotive 2, the controller 3 is turned off, the signals from its outputs to the elements OR 5 and 6 and block 4 are not received, and it does not affect the control devices "Block 4 executes commands that come from the output of the decoder 9, and performs command control through the element OR 5 by the executive unit 11, and through the synchronization machine and the element OR 6, by the executive unit 15, the control unit of the executive units 11 and 15 trigger the signals from their control outputs through the memory unit 12 to the encoder 14, with the output and which through the second communication line - to the input of the decoder 9 of the leading locomotive 1.

The device implements two control modes of the slave locomotive 2 - synchronous and asynchronous, which are selected by the switch

13 modes. In the synchronous mode, all commands generated by the controler 3 of the leading locomotive 1 are received through memory block 2 to the input of the encoder 14 and through the communication line to the decoder 9 input of locomotive 2, then through block 4 and the automatic synchronization machine 8 the commands arrive to the blocks 11 and 15 of the slave locomotive 2. In asynchronous mode, memory unit 12 is translated into reads. In this case, the new information is not perceived and the information at the output of unit 12 will not change when the state of the command unit 3 and the driving locomotive control devices changes.

The presence of the asynchronous mode allows, with non-convergence, to leave the driven locomotive 2 in any mode, for example, in a driving position of the driver's controller, and the driven locomotive 1 to specify another operating mode

In synchronous mode, the operation of the synchronization machine on the slave locomotive 2 is as follows: from the output of block 4, information about the status of the first command device 3 of the leading locomotive 1 is fed to the input of the memory register 16 The input of the memory register 17 receives the information from the control output of the slave actuator 15 Locomotive 2 "In these registers, the number of the running position in which the driving and driven locomotives are located is essentially stored in coded form. If one or both locomotives are located at an intermediate position (for example, in the process of recruiting positions), then the number of the previous running position is stored in the corresponding register. The change of information at the control output of the execution unit 15, and consequently, in the registers, occurs only at the exit of the running gear position The comparison unit 18 compares the contents of the register with the contents of the register 16. In case of inequality of the running position numbers, the comparison unit 18 generates a signal that arrives at the control input of the block 20. In the absence of the control signal, the switching unit 19 of the control command, which comes from the lead locomotive, transmits to the input of the element OR 6, from the output of which commands

the control is fed to the input of the execution unit 15c. The arrival unit 20 to its control input signal from the output of the comparison unit 18, in the event of a discrepancy in positions, sets the unit 21 to the position set or reset mode. The generation unit 21 generates the control signals to be input. block 19 switching, and from its output to the input of the Executive unit 15, which causes the set or reset of the positions of the locomotive. The speed of recruiting or resetting the positions is determined by the frequency of the multivibrator 22, which comes from its output to the digital input of formation unit 2. When the codes of numbers in registers 16 and 17 coincide at the output of comparator unit 18, the signal disappears and the position is set or reset.
