TRAIN DIRECTION AND ROUTE DETECTION VIA WIRELESS SENSORS

摘要

Systems and methods for detecting train direction and route along a railroad track such that a constant warning time for a level crossing is provided. Wireless magnetic sensors (magnetometers) are used to detect the train at at least two points on the track, from which the train presence and direction is derived. The sensors communicate wirelessley with a basestation, which passes the data on to a wayside inspector for calculation of the direction and route.
