Patent Images
1. A system for detecting location, speed and heading information of a moving object in a predefined protected area, the system comprising:
- a plurality of processor-based sensor node devices arranged in spaced relation to one another to establish the predefined protected area, each of the plurality of processor-based sensor node devices including at least one detection element configured to sense at least one of the location, speed and heading of the moving object within the predefined protected area; and
at least one concentrator node device in communication with each of the plurality of processor-based sensor node devices when the moving object is within the predefined protected area.

Abstract
A railroad car location, speed and heading sensor system including at least one self-powered, tie-mounted sensor node that is applicable universally to different railroad settings without using track circuits, inductive loops, radar systems, and wheel counters and associated disadvantages. Reliable and relatively low cost deterministic and redundant car presence detection is realized when multiple sensor nodes are arranged in a network, which may be a wireless mesh network, that is not affected by environmental conditions.
