SYSTEM FOR DETERMINING WHETHER RAILWAY SECTIONS ARE FREE FROM ROLLING STOCK Russian patent published in 2024 - IPC B61L1/00 B61L21/06 

FIELD: rail vehicles; measurement.

SUBSTANCE: invention relates to means of determining vacancy of track sections, equipped with systems with point track sensors, on which traction rolling stock equipped with radio data exchange systems operates. System consists of two semi-sets of equipment installed on counting sections (1) of stations, limiting section (2), each semi-set of equipment contains installed on the control track section of the corresponding counting section rail sensors (3), signal generator (4), receiver unit (5), interface unit (6) with axes counters, local communication line (7), interface unit (8) with electrical centralization, control unit (9), interface unit (10) with a long-range digital radio communication channel, to which radio modem (11) with an antenna is connected. At each of intermediate sections (12) of the railway haul, at least one intermediate counting station (13) is located, including stationary transceiving unit (14) of a low-power digital short-range communication channel, which further comprises GSM transceiver module (15), low-power short-range digital radio channel stationary transceiving unit (14) control port, microcontroller (16), interface (17), passive wheel passage sensor (18), self-contained power supply (19). On each locomotive (24) of rolling stock there is transceiver (25) of long-range and short-range digital radio communication channels, which by means of local line (26) is connected to central on-board device (27) of rolling stock movement control, in electronic memory of which there recorded are electronic maps of locomotive movement routes, unit (28) of point corrections of coordinates of locomotive locations. Transceiving units (14) of counting stations and transceiving devices (25) of locomotives (24) are equipped with program clocks with possibility of their mutual synchronization during radio data exchange between counting station and locomotive.

EFFECT: increasing locomotive positioning accuracy without using a differential correction system for the locomotive satellite navigator.
