Abstract

Railroad car 1 is identified by recognition of reversals in flux direction encountered during passage of an array 2 of permanent magnets past a receiver 3. Magnets 4 are arranged in North South and South North positions to establish a particular code representation of binary ones and zeros with accompanying flux patterns 5.

Railroad Car Surveillance

Railroad car 1 is identified by recognition of reversals in flux direction encountered during passage of an array 2 of permanent magnets past a receiver
3. Magnets 4 are arranged in North South and South North positions to establish a particular code representation of binary ones and zeros with accompanying flux patterns 5.

Receiver 3 is a single multi-turn coil mounted between tracks 6 with its axis parallel to the tracks. The center of the coil in 3 is four inches below the magnets 4, when the car 1 passes over receiver. The first magnet to pass over 3 is of some standard length, e. g., four inches, in order to ""set the clock for the particular train speed. The arrangement of the first four magnets 4 as shown, creates flux reversals at 7, 8 and 9. If an NRZI system of recognition is used, the binary designation of car 1 is represented by flux pattern changes, indicated by wave form 10.
