ROUTE EXAMINING SYSTEM

摘要

Systems 102 for examining a route inject one or more electrical examination signals into a conductive route 108 from onboard a vehicle system 100 traveling along the route 108, detect one or more electrical characteristics of the route 108 based on the one or more electrical examination signals, and detect a break in conductivity of the route 108 responsive to the one or more electrical characteristics decreasing by more than a designated drop threshold for a time period within a designated drop time period. Feature vectors may be determined for the electrical characteristics and compared to one or more patterns in order to distinguish between breaks in the conductivity of the route 108 and other causes for changes in the electrical characteristics.
