С

the output of the analog-digital converter 9 to the other input of the comparison unit 5 and to the third input of the coding block 6-2Q information about the magnitude of the recovery current of the driving locomotive 17, presented in binary code. The other inputs of coding unit 6 receive information for switching the control unit 7 of the slave locomotive 18. From the output of the coding unit 6, the signal goes to one of the inputs of the comparison unit 8, and through the communication line to the input of the decoder 3 of the slave 30 locomotive 18 the status of the control devices and the presence of the recovery current of the driving machines of the lead locomotive 17 are transmitted.

On the slave locomotive, there is an 18 recovery box, the input of which is connected-. devices 1 and 14 are turned off and on to the output of the logic element of the circuit from the output of the decoder 3. Information OR 13, whose inputs are connected to the nation from the output of the decoder 3, through the outputs of the command device 14, the recuperative element OR 2 enters the correction unit 15, connected - to the input of the control unit 7. From the output inputs to the outputs of block 5, compared to 40 block of control 7 to the input of block 6 and a timer 16 connected by the input to the output of block 5 of comparison. The output of coding unit 6 of lead locomotive 17 is connected to other inputs of decoder 3 and block 8, comparing slave locomotive 18, the output of coding unit 6 of which is connected to other inputs of decoder 3 and block 8 comparing lead locomotive 17.

A device for controlling articulated locomotives operates the following encoder 3, to the output of which one of the inputs of signaling and comparison blocks 4 and 5 are connected and another input of an OR 2 logic element, with the output of which is connected to one of the inputs of the coding unit 6. and the stroke of the locomotive control unit 7 connected output to the second input of coding unit 6, the output of which is connected to one of the inputs of comparison unit 8 connected by the output to another input of alarm unit 4, analog-to-digital converter 9, the output of which union of the third input of the coding unit 6 and the other input of the comparison unit 5 and input - with the recovery current sensor 10 to move in! teley the traction 11 and the control unit 12 receives tokodirovani status information locomotive slave control devices. Information about the recovery current of the driving locomotive from the output of the decoder 3 is fed to one of the inputs of the comparison unit 5, the other input of which receives the information about the recovery current of the slave locomotive 18 from the output of the analog-digital converter 9 of the driven locomotive 18, In the block In comparison, the values of the recovery currents of the driven and driving locomotives are compared and at its output in turn.

In the regenerative braking mode, when the controllers 1 and 14 are turned on on the leading locomotive 17, the signals from them come to one and the: inputs of the decoder 3 and the logic element OR 13, respectively. Signal

from the output of the decoder 3 enters the block 4 alarm. On the service {ae, on the lead locomotive 17, the operation of the slave locomotive control unit 7 is signaled. The signal received at one of the inputs of the OR 13 logic unit turns on the regeneration current control unit 12. Depending on the signal coming from the output of the command device 14, unit 12 dials the corresponding braking position. Current sensor 10 measures the current recovery value of the traction motor on the slave locomotive 18, commander 1 and 14 are switched off and the circuits from the output of the decoder 3 are turned on. Information from the output of the decoder 3 through the logical element OR 2 is fed to the input of the control unit 7. From the output 40 of the control block 7 to the input of the block 6

coding information is received about the state of the slave locomotive control devices. Information about the recovery current of the driving locomotive from the output of the decoder 3 is fed to one of the inputs of the comparison unit 5, the other input of which receives the information about the recovery current of the slave locomotive 18 from the output of the analog-digital converter 9 of the driven locomotive 18, In the block In comparison, the values of the recovery currents of the slave and driving locomotives are compared, and at its output a gg error signal L1p appears.

This signal arrives at the control input of the correction unit 15 and starts the timer 16. After a predetermined time, the timer 16 generates a signal that arrives at the other input of the correction unit 15. According to this signal and depending on the sign of TTR, the unit 15 increases or decreases the brake position number by one. And} information about the number of the brake position through a logical element ISH1 13 enters the input of block 12. Depending on the number of the brake position, the resistance of the excitation circuit of the traction machine 11 changes. At the same time, the excitation current and, therefore, the regeneration current, Sensor 10 current measures the changed value of the recovery current, and the analog-to-digital converter 9 converts it into a binary code that is fed to another input of the comparison unit 5. Then, the values of the current recovery of the driving and driven locomotives are re-compared, and in the case of the output of the comparison unit of the error signal ± ulp, timer 16 is again activated. After a specified time, timer 16 generates a signal according to which correction unit 15 increases or decreases by one brake position number. This, in turn, leads to a new change in the magnitude of the recovery current of the driven electric locomotive. The braking position process continues until the error signal is present at the output of the comparator unit 3. When the values of the recovery currents of the master and slave locomotives are compared, the signal for turning on the timer 16 is not received and the correction unit 15 remains in the previous state.

The time between two changes in the brake position number is determined by the duration of transients in the electrical circuits of the locomotive,

The device for monitoring the health of the device serves as a comparison unit 8, which compares the output signals of the coding unit 6 on the driven and driving locomotives. If the output signals of the coding units are the same, this means that the sets of equipment on the driven and driving locomotives are working properly. If the comparison unit 8 detects a discrepancy in the output signals of the coding blocks of the master and slave locomotives, then the output of the comparison unit 8 receives a signal to another input of the signaling unit 4 of the existing fault. Because

there is no locomotive crew on the driven locomotive, then the alarm unit 4 on the driven locomotive is turned off,

A device for controlling articulated locomotives is constructed in such a way that the locomotive can be both a master and a slave. Switching the mode of operation of the locomotive from master to slave or vice versa can be carried out by toggle switches in control units 1 and 14
