Abstract
<jats:p>В статье представлена методика, позволяющая измерить значения А-параметров четырехполюсника путевого фильтра ФПМ тональных рельсовых цепей (ТРЦ) с учетом условий его работы в конкретной ТРЦ, что повысит адекватность цифрового двойника данной ТРЦ.</jats:p> <jats:p>Russian railway transport has entered a phase of digital transformation and intellectualization, which includes the development and practical application of digital twins for railway infrastructure objects. When developing and updating digital twins, the quality of methodological support for these processes is of great importance, and it must be adapted to modest university equipment. Digital transformation is at an initial stage; there is much work ahead, and it is necessary to train personnel already now. The article presents a methodology that allows measuring the A-parameter values of the four-terminal network of the FPM track filter of tonal track circuits (TTC), taking into account the conditions of its operation in a specific TTC, which will enhance the adequacy of the digital twin for this TTC.</jats:p>
