О технических методах снижения числа сбоев в работе основных локомотивных устройств безопасности

Abstract

Violations in operation of receiving equipment of safety locomotive major devices due to the hindering effect of electromagnetic interference (failures) are a rather frequent phenomenon on the railway network of the Open Joint Stock Company «Russian Railways» in the conditions of electromagnetic environment that has changed dramatically with active introduction of modern electric rolling stock. On the one hand, failures are the result of discrepancy of own parameters and operation algorithm of receiving equipment of safety locomotive major devices opposite interference, existing in inductive coupling channel of automatic locomotive signaling. On the other hand, it is a consequence of the lack of regulatory documentation with uniform established requirements for interference parameters under the influence of which, safety locomotive major devices, primarily built on a relay element base, shall provide for regular operation. Over the past decades, numerous and different by their technical essence attempts have been made to resolve these antagonistic contradictions. This work is one of the first attempts to generalize and analyze the results of pursued research and developments. The work is based on the results of a patent study conducted by the authors in order to identify trends in technical measure development to improve noise immunity in operation of safety locomotive major devices. On their basis, the authors proposed, described in detail and substantiated main technical methods for reducing failure number in the operation of safety locomotive major devices. The obtained results may be of interest to specialists involved in technical servicing, repairment, development and improvement of safety locomotive major devices and will be used further in the development of the theory of locomotive automatic signaling numerical code.
