The invention relates to the monitoring of the state of the braking means of a railway train, in particular the operability of the brake line.

The purpose of the invention is to increase reliability.

The drawing shows a block diagram of a device for controlling a train brake line.

The elements of the device are placed on the locomotive 1 and the tail car 2 trains.

The device contains a memory block 3 with a train number dialer 4, a transmitter 4 encoder 4, a transmission command unit 6, and a receiver 7 with a decoder 8, a coincidence block 9, an indicator 10 located on the platform 1, and an end valve 11 is installed at the end of the train On the tail car there are receiver 12 with decoder 13, memory and comparison block 14, train number recording block 15, recording command driver 16, as well as pressure sensor 17 with encoder 18, transmission information driver 19, encoder 20, transmitter 21. In locomotive about In operation, the memory block 3 is connected to one of the outputs of the encoder 4, the output of which is connected to the input of the transmitter 5. The receiver 7 is connected to the input of the decoder 8, the output of which is connected to the input of the coincidence unit 9, one output of which is connected to the indicator 10, the second output with the input of the transmission command generation unit 6, one of the outputs of which is connected to the input of the unit 3, the second one with the indicator 10.

The second output 3 is connected to the input of the coincidence unit 9. In the tail car 2, the receiver 12 is connected by a sat input of the decoder 13, one of the outputs of which is connected to the input of the memory and comparison unit 14, the second output - to the input of the train number 15 recording unit, the output of which is connected to the input of the memory 14 and comparison connected with the output of the shaper command to write, the output with the transfer information generator 19, which is connected via the encoder 18 to the output of the pressure sensor 17, which is connected to the brake line via the end valve 11. The output of the shaper 19 is connected to the input m coder 20 whose output is connected to the transmitter 21. The tail and locomotive equipment are interconnected radio link.

The device works as follows.

When tailing equipment is installed at the end of a train, the operator uses a wearable radio station to transmit to the driver information that he has installed the device, while the driver sends the number assigned to the train,

which the driver is bound to enter into the radio station when the locomotive is supplied for the train. The operator with the help of the corresponding button (the former 16 commands for the letter) allows the recording of information.

When a brake line connecting to the end valve 11 is connected to the device, the air pressure is recorded by the pressure sensor 17, encoded by encoder 18 and fed to shaper 19. The train number entered by the machinist in memory block 3 is encoded by encoder 4 and transmitted to radio signal by transmitter 5 to the tail carriage 2. This signal, having passed through the receiver 12, the decoder 13, falls into the block 14 of memory and comparison.

At certain time intervals, the train’s number from the locomotive is repeated (it is also a signal

request), the received number is compared with the number recorded in block 14 of memory and comparison. If the numbers stored in block 15 and recorded in block 14 match, the latter is transmitted to the imaging unit 19.

The combined information about the pressure value and the train number is fed to the encoder 20 and the transmitter 21, and after being converted into a radio signal, it is broadcast.

to locomotive 1. Here it is received by receiver 7, fed to decoder 8 and then to the first input of block 9 of coincidence, to the second input of which the train number from block 3 is fed.

trains display information about pressure values on indicator 10. This decision eliminates the perception of signals from oncoming or following trains.

When pressure changes in the event of braking, pumping or leakage in the brake line t, a pressure sensor generates the corresponding information on the pressure value in the brake line by transmitting it. The value of the pressure at the end of the brake line of the train received on the locomotive is highlighted on the digital display of the indicator 10. If the device is defective, on the display

There is a fault signal. This is provided by the link between the transmission command generation unit 6 and the indicator 10. The output of the coincidence unit 9 is connected to the input of the transmission command generation unit 6 in order to provide a reset of the reference time of the transmission of the request signal (train number).

In the event of a brake line breakage on the digital indicator will be zero by; kazani pressure.

The tail equipment is universal for all trains, as the train number is entered using a transmitter from the driver's cab and does not require a special dialer.
