SYSTEM FOR CALCULATING DELAY TIME OF RAILWAY CROSSING CLOSURE Russian patent published in 2017 - IPC B61L29/22 

FIELD: information technology.

SUBSTANCE: system comprises, combined by the common data bus: a processor, a memory means, an information collecting and rail circuit state determining unit that is configured to determine the voltage and current at the feed end of the rail line and the approach section of the rail line in the shunt mode, a coordinate and rolling stock determining unit, a data storage unit on the permissible shunt mode operating values of the rail circuit, a closure delay time calculating unit, which is configured to compare the parameters, and a crossing closure controlling unit. Moreover, the crossing closure controlling unit is configured to activate the automatic alarm devices based on the crossing closure coordinate value received at the unit input.

EFFECT: improving the accuracy of determining the time of the train approaching the crossing.
