TRACK TRANSMITTING TRAIN CONTROL DEVICE Russian patent published in 2012 - IPC B61L1/18 B61L3/00 B61L21/00 

FIELD: transport.

SUBSTANCE: invention relates to railway automatics and telemechanics, in particular to devices of automatic locomotive signalling (ALS), and can be used in train automatic control systems using coded tone rail circuits without lock joints. The device contains control unit and signal logical processing unit, transmitting unit including train detection and train control single signal generator which is connected with modulator by its output. The device also contains amplifier the output of which is connected with rail line, and receiver containing series-connected analog-to-digital converter and program attenuator the output of which is connected with signal logic processing unit which is connected by its first output to the input of train detection and train control single signal generator, and by its second input an its second output connected via local network to the output and input of control unit respectively. Transmitting unit of each rail circuit includes additional train control signal generator the output of which is connected with other input of modulator and the input - with the third output of signal logic processing unit, and complex signal generator connected between modulator output and amplifier input. Transmitting unit and receiving unit of adjacent rail circuits are mutually connected to rail line.

EFFECT: functionality enhancement of train control track transmitting device by means of arrangement of communication with rail line when there is rail circuit without lock joints, as well as reducing trains delay in case of haul rail circuit failure due to generation of additional signal of locomotive signalling.
