ALS AUTOMATIC LOCOMOTIVE ALARM SYSTEM Russian patent published in 2024 - IPC B61L25/06 

FIELD: railway automation.

SUBSTANCE: invention relates to railway automation and can be used in automated train control systems to transmit information to a locomotive via an inductive rail line. The technical result is achieved by the fact that the ALS-TTS automatic locomotive signaling system of extended significance and increased noise immunity, containing a power amplifier, a protection and matching device, a rail line and receiving coils, and the output of the power amplifier connected to the input of the protection and matching device, the output of which is connected to the input of the rail line, the output of the rail line is connected to the input of the receiving coils connected in series, an additional encoder of the modified inverse code in the SG subchannel and the code with parity check in the CC subchannel, a signal generator with two-fold minimum frequency manipulation (MFM2), a receiver direct amplification, an autocorrelation demodulator, a zero detector, a clock synchronization system, a level lock, a quadrant determinant, a decoder, a decoder of the modified inverse code in the SG subchannel and a parity-checked code in the CC subchannel, as well as a driver interface unit, and the input of the encoder of the modified inverse code in the subchannel SG and the code with parity check in the CC subchannel is also the input of the signal generator, the output of the encoder of the modified inverse code in the SG subchannel and the code with parity check in the CC subchannel is connected to the input of the signal generator with MFM2, the output of which, which is also the output of the signal generator, is connected to the input of the power amplifier, the input of the direct gain receiver, which is also the input of the electronic locomotive unit, is connected to the output of the receiving coils connected in series, and the output of the receiver is connected to the input of the autocorrelation decoder, the output of which is connected to the input of the zero detector and the first input of the level lock, the output of the zero detector is connected with the input of the clock synchronization system, the output of which is connected to the second inputs of the level lock, quadrant determinant and decoder, the output of the level lock is connected to the first input of the quadrant determinant, the output of which is connected to the first input of the decoder, the first and second outputs of the decoder are connected respectively to the first and second inputs of the decoder of the modified inverse code in the SG subchannel and the c code by checking for parity in the CC subchannel, the output of the decoder of the modified inverse code in the SG subchannel and the code with parity check in the CC subchannel, which is also the output of the electronic locomotive unit, is connected to the input of the driver interface unit.

EFFECT: technical result, which is aimed at creating a utility model, is to increase the information capacity of the automatic locomotive signaling system and the reliability of receiving its signals.
