The known system has a lack of reliability of the brake control trains increased weight and length, due to the possibility of breaches in data transmission over the radio channel, connecting the locomotive with BL is kOhm tail carriage under the influence of external interference in the path of the train.

The technical result of the invention is to improve reliability of the brake control trains increased weight and length.

The technical result is achieved that the control system brakes of trains increased weight and length, consisting of a locomotive and carriage sub-assemblies, placed respectively in the cab of the locomotive and on the free automatic coupling of the tail of a train locomotive terminal includes a controller locomotive braking, respectively connected with the display unit and the input data, a valve on the brake line of the train, by the registration module, the interface block signal system with automatic brake control, and a radio, and the radio station of the train radio hectometric range of radio waves, and the radio and the radio station of the train radio hectometric range of radio waves through the duplex filter is connected to the antenna-feeder device and the car terminal includes a transmitter connected to the antenna-feeder device through the radio and through the air module with brake train line, according to the invention in the locomotive entered the terminal of the signal Converter, the output of which is connected to the input data of the radio station of the train radio hectometric range of radio waves, and the entrance is dine with the regulator locomotive braking, and the block select communication channels VHF and hectometres ranges of radio waves, the input/output of which is connected with the corresponding output/input unit and the output with the control input of the radio station of the train radio hectometric range of radio waves in the wagon entered the terminal receiver hectometric range of radio waves, the output of which is connected to the computer.

The drawing shows a system diagram of a brake control trains increased weight and length.

Power supply locomotive terminal and the power source (battery) car terminal not shown in the figure.

System brake control trains increased weight and length operates as follows.

Car terminal 14 mounted on the free automatic coupling of the tail of the train.

When powering on the unit locomotive terminal 1 starts to operate all units of the equipment of the locomotive to be carried out 1.

Communication between equipment railcar terminal 14 and locomotive equipment of the terminal 1 is initiated by the equipment of the locomotive to be carried out 1 at a predetermined interval via a radio channel meter range of the radio waves and the radio hectometric range of radio waves. Equipment car terminal 14 taking the em data packets from the equipment of the locomotive to be carried out 1, and in response transmits the data packet through the radio 17 meter band radio waves over the air meter range radio waves.

Knob 2 locomotive braking produces a self-test and displays the test result on the display unit 3 and input. The locomotive through the keyboard unit 3 display and input enters the required service information. Knob 2 locomotive brake support brake line 5 train air pressure specified by the driver. The driver, making the procedure enters in the display unit 3 and input individual number of car terminal 14, after receiving this room controller 2 locomotive braking passes on unit 8 meter range radio package of information containing a request for railcar terminal 14 with the data of the individual number. Unit 8 converts this information into a radio signal and waits for transmission of a radio signal through the antenna-feeder device 11 in the channel meter range radio waves. After the data packet transfer unit 8 passes in a mode of reception of the response signal. Unit 17 converts passed through the antenna-feeder device 16, the radio signal from the radio meter range of the radio waves into a digital signal and transmits it to the transmitter 15, which sravnivai the individual number received with a packet of information, with the number of car terminal 14, recorded in the memory of the computer 15. If individual numbers match, the computer 15 executes the commands contained in the data packet, if necessary, acting on the air module 18. After receiving the data packet and commands the transmitter 15 transmits via radio modem 17 and antenna-feeder device 16 in the channel meter bands more response packet data. After the data transfer unit 17 enters the reception mode signal.

Knob 2 locomotive braking, receiving information from the car terminal 14, and compares the received individual number with the number entered by the locomotive engineer, and outputs the service information on the display unit 3 and input. All sent and received commands are registered by the module 6 of the Desk. Unit 7 coordination with the automatic brake control permits operation of the system for braking when designing the system SOUTH of the commands on the brake.

The control signals from the locomotive terminal 1 car terminal 14 are received in overlapping radio channels hectometric range of radio waves from the radio station 10 the train radio and meter range of the radio waves from the radio modem 8.

When used for braking of a train stump is malloca 18 car terminal 14 he receives overlapping control signals from the radio modem 8 meter range of the radio waves, connected to the regulator 2 locomotive braking, and from station 9 train radio hectometric range radio connected to the controller 2 locomotive braking through the transducer 12 signal, converts a signal from the controller 2 in the form required for transmission by the radio station 10 train radio hectometric range of radio waves.

Through the antenna-feeder device 11 in unit 8 meter range radio in receive mode in addition to working radio signals received interfering signals from various sources of radiation and external interference. Radio signals are received in block 13 of the choice of communication channels VHF and hectometres ranges of radio waves, which selects the carrier frequency meter and hectometres ranges of radio waves by the criterion of minimum measured level of interference from external sources of interference at the current location of the train. These frequencies are transmitted as part of data packets to rebuild them communication equipment when you commit increasing the level of interfering radio interference on the current radio frequency. The choice of frequencies with minimum noise level reduces the probability of errors in transmission of information across every channel and even more at the same time on both channels. To make it possible thirupati receivers of radio signals in all units of the equipment are always at the beginning of the synchronization preamble of the received packet check frequency, where the packet, and then take the full package on the correct frequency.

When using channel train radio hectometric range priority in the transmission usually has information for negotiation by the driver, except in the case of transmission of commands to the braking of a train on this channel.

Rebuilding frequency achieves reliable protection from loss of communication between the locomotive terminal 1 and car terminal 14 of the tail of the wagon.

In the proposed system, this is achieved with a relatively small hardware redundancy compared to, for example, with known complete duplication of the communication equipment. The win is that in car terminal 14 no transmitter hectometric range, which greatly increases the size and energy consumption from the supply battery.

In case of malfunction of one of the radio channels, for example when exposed to industrial (pulsed) interference or interfering influence of technological radio communication, efficiency is achieved through the use of the radio channel to another radio wave range. The use of radio hectometric range as a backup allows you to increase the reliability of data transfer on curved sections of railway track on otkritochnoe and tunnels through the use of diffraction of radio waves hectometric range.

In car terminal 14 computer 15 is in constant control information received by radio 17 meter band radio waves and a receiver 19 of the train radio hectometric range of radio waves. Data about the new frequency settings in the car terminal 14 take the receiver 19 hectometric range of radio waves and radio 17 meter band radio waves. In the locomotive terminal 1 of the normal operation of the receiver 19 is judged by the fact add-ons package handshake from unit 17 unit 8 meter range radio waves testing information, adopted by the receiver 19 hectometric range of radio waves from radio stations 9 train radio hectometric range of radio waves.

If the packet handshake comes without updating this information, it is a sign of unreliable operation of the radio hectometric range of radio waves. If the packet handshake comes with errors in the code control CRC of the transmitted primary message, it is a sign of unreliable operation of the radio meter range radio waves.

One of the preferred algorithms use the system is such that if the diagnostic system detects a permanent failure of communication on one channel, it produces a warning signal for the driver of comp is anii of premadasa, and if the refusal is recorded on both channels, the system generates a warning signal about a complete failure and displays on the display unit 3 and enter the recommended value of the speed at which enough braking without the participation of the car in the terminal 14.

The sustainability of this radio system is additionally achieved by encryption of commands and addresses.

To increase the reliability verification fully functional car terminal 14 can outstripping inclusion in the beginning of the braking air module 18 with the fixation on the locomotive started slowing the train and then go to turn on the brake with the knob 2 locomotive braking.

The invention improves the equipment is ready car terminal 14 to perform the most important functions start braking with the rear of the train by the command transmitted from the locomotive, and this significantly improves the reliability of the braking of trains increased weight and length.
