Determination of the optimal parameters of the control sensor at the crossing in the control mode

On railway sections where there are intersections with road transport, control systems for crossing signaling auto barriers arranged. To the entrance of train to this section, track circuits insulating joints used. Such have a number significant drawbacks, one which is coming off joints, as well breakage circuit, give 45% failures automation on haul. In article, study was made circuit tone frequency mode. For study, mathematical expressions determining most unfavorable moment were derived, an algorithmic expression mode coefficient presented, gives more accurate information about presence damage. As result, block diagram developed and graphs displayed simulation model showing influence determination operation jointless circuit. conclusion, results summarized.
