RECEIVER OF TONAL RAIL CIRCUIT

摘要

FIELD: transport. ^ SUBSTANCE: invention relates to technical safety facilities for railway transport and is intended to be used in adjacent tonal rail circuits (TRC) of different length with common feeding node. Receiver installed on relay end of TRC of less length consists of receiving unit in from of TRC current sensor and device for voltage equalisation at its output. Voltage equalisation device includes band-pass filter, controlled divider, threshold element and external interface support unit. Voltage equalisation is fulfilled by dividing receiver output voltage by equalisation factor specified with required discretisation. ^ EFFECT: more precise voltage equalisation. ^ 1 dwg
