AI Technical Summary

Benefits of technology

The present invention is a system for detecting movement of railroad tracks using GPS data collected from sensors attached to railroad ties. The system includes multiple data collection units, a base unit, and a data processing server. The data collection units transmit the collected GPS data to the base unit, which then sends it to the server. The server processes the data to determine the amount of lateral and vertical displacement of the railroad track. The system may also include devices for measuring seismic activity, temperature, wind speed, and precipitation, which would also be included in the reports generated. The technical effect of this invention is to provide a reliable and accurate system for detecting railroad track movement.

Problems solved by technology

Sections of railroad track, and in particular curved sections of railroad track, tend to move over time.
This is primarily due to temperature changes causing expansion and contraction of the rails and the action of passing trains on the rails, however other factors such as soil erosion, seismic activity and the like may also affect the position of the tracks.

Abstract

A system for monitoring movement of railroad track includes a plurality of data collection units secured to respective railroad ties in a curved section of railroad track. Each data collection unit includes a GPS receiver. The data collection units collect location data from the GPS receivers and transmit the location data to a base unit. The base unit collects the location data from the data collection units and periodically uploads the location data to a server. Software on the server reviews the data for any changes in location of the data collection units and reports the results to a user or users.

Description

[0001]This application claims the benefit of provisional patent application Ser. No. 61 / 777,116 filed Mar. 12, 2013.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]This invention relates to railroad track monitoring and maintenance, and in particular to a system for monitoring movement of railroad track using GPS.[0004]2. Description of the Related Art[0005]Sections of railroad track, and in particular curved sections of railroad track, tend to move over time. This is primarily due to temperature changes causing expansion and contraction of the rails and the action of passing trains on the rails, however other factors such as soil erosion, seismic activity and the like may also affect the position of the tracks. Track movement need to be monitored in order to insure that the track remains safe.SUMMARY OF THE INVENTION[0006]The present invention is a system for detecting movement of railroad tracks. The system includes a plurality of data collection units, a base unit...
