Embodiment Construction

[0014] Figure 1 is a schematic diagram of an exemplary embodiment of the present invention. As shown, the sensor assembly 10 includes a sensor 12 and an embedded processor 14 . The sensor 12 is a three-axis magnetic sensor 12, such as a Honeywell HMC2003 three-axis magnetometer. The sensor 12 measures the strength of the low magnetic field along the X-axis, Y-axis and Z-axis, wherein changes in the magnetic field around the sensor beyond a given range can be detected. In a preferred embodiment, the sensor provides an analog signal and uses the ground or earth as a magnetic field reference.

[0015] The processor 14 is arranged to allow communication of magnetic field readings between the sensor 12 or sensors 12 connected to the processor and the wayside or communication equipment 16 and / or the locomotive 18 . Communications may occur over an industry standard network such as, but not limited to, a Controller Area Network ("CAN"). CAN is an important protocol used by the ele...

Abstract

A system for determining the capability of a railroad track to safely carry railroad vehicles over the track by sensing changes in the environment proximate the track, the system including a sensor for detecting a magnetic field proximate the railroad track and generating data indicative of the magnetic field, a processor for processing data from the sensor to identify changes in the magnetic field proximate the track, and a communication device in communication with the processor for transmitting indicia indicative of changes in the environment proximate the track affecting the capability of the track to safely carry railroad vehicles.

Description

technical field [0001] The present invention relates to rail transportation, and more particularly to sensing rail washout, rail deflection, pumping ties, and / or vehicle parking on railroad crossings. Background technique [0002] Railway tracks typically have a pair of rails supported by a plurality of vertically positioned sleepers resting on ballast material. Many railway tracks are located in remote areas where the condition of the track may not be readily known without known incidents that could damage the track. For example, railroad tracks or rails may be damaged due to snowstorms or other natural events such as earthquakes (in which case the tracks may become displaced). Shifting can be caused by movement of sleepers and / or displacement of ballast material. In other cases, such as where the track is adjacent to a body of water, the ballast may move or wash out causing the sleepers and thus the track to shift. The tracks may also be displaced by human accidents suc...
