AUTOMATIC INTERLOCK DEVICE Russian patent published in 2019 - IPC B61L23/16 

FIELD: transport traffic control systems.

SUBSTANCE: invention relates to automatic interlocking means on railway transport for interval control of motion. Device comprises enclosing block-sections of track through traffic lights 1, 2, 3 and 4, connected to corresponding signal light control blocks 5, 6, 7 and 8, on each of block-sections there installed is automatic interlocking and automatic locomotive signaling equipment, which includes driver track control signal generator 9 and automatic locomotive signaling signals, first output of which is connected to input of automatic locomotive signaling signals selection block 10, and its second output is connected through first matching block 11 to beginning of block-section rail circuit, and end of track circuit of block-section is connected to input/output of second matching block 12, output of which is connected to input of track receiver 13 of rail circuit signal of this block-section, wherein the input of the second matching block 12 is connected to the output of the locomotive signaling signal selection block 10, the operation inhibit input of which is connected to the output of track-type receiver 13 of the rail circuit signals of block-sections. At that, in each set of automatic interlocking and automatic locomotive signaling equipment, installed on a block-section of increased length, block 14 is installed for fixation of head passing of train of the first half of this block section, which is connected via communication channel with signal repeater 15, the output of which is connected to the configuration control input of block 10 for selection of signals of automatic locomotive signaling, which are supplied to the rail line of this block-section.

EFFECT: higher carrying capacity of railway line.
