System for calculating ratio of contact loss using current wave form analysis of pantograph

摘要

The present invention relates to a system for calculating a contact loss ratio using current waveform analysis of pantograph. The objective of the present invention is to provide the system for calculating a contact loss ratio by analyzing, in real time, a current waveform after a current of pantograph is measured to evaluate current collecting performance and by calculating contact and non-contact time between the pantograph and all lanes. To achieve the objective, the system of the present invention comprises: a current measuring unit to measure a current of pantograph; a waveform analyzing unit to analyze a waveform of the measured current of the pantograph and calculate contact and non-contact time (contact loss time) between the pantograph and all lanes; and a contact loss ratio calculating unit to calculate the contact and non-contact time (contact loss time) between the pantograph and all lanes using the results analyzed by the waveform analyzing unit and measure dispersion values of signals to calculate the contact loss ratio of all lanes.
