Abstract

A system and method for data logging, collection, and analysis techniques. Logging, collection, and analysis of data relating to the condition of a structure, such as a railway rail. Monitoring the neutral temperature of a railway rail.

Claims

1. A system for monitoring the neutral temperature of a railway rail, the system comprising:

(a) a field sensor system installed on a rail at a railway site, where the field sensor system is configured to collect data for use in calculating the neutral temperature of the rail at the railway site, where the field sensor system collects a first set of data for use in calculating the neutral temperature of the rail at the railway site, and where the field sensor system later collects a second set of data for use in calculating the neutral temperature of the rail at the railway site;

(b) a wireless network that is capable of transferring data from the field sensor system to a remote location for evaluation of the data collected by the field sensor system; and

(c) an apparatus that is not located at the railway site, and that evaluates the neutral temperature of the rail at the railway site based on the first set of data collected at the first railway site and the second set of data collected at the railway site.

2. The system of claim 1, where the apparatus determines whether the condition of the rail is potentially unsafe due to the potential of a rail break.

3. The system of claim 1, where the apparatus determines whether the condition of the rail is potentially unsafe due to the potential of a rail kink.

4. The system of claim 1, where the field sensor system has been calibrated at the rail site in connection with its installation at the railway site.

5. The system of claim 1, where the field sensor system is installed at the rail site through a process that includes determining the initial neutral temperature of the rail at the rail site.

6. The system of claim 1, where the apparatus is configured to receive the first set of data and the second set of data collected at the railway site using a vehicle traveling on the railway rail.

7. The system of claim 1, where the apparatus is configured to receive the first set of data and the second set of data collected at the railway site without assistance from data collection personnel.

8. A system for monitoring the neutral temperature of a railway rail, the system comprising:

(a) a first field sensor system installed on a rail at a first railway site, where the first field sensor system is configured to collect data for use in calculating the neutral temperature of the rail at the first railway site, and where the first field sensor system collects a first set of data for use in calculating the neutral temperature of the rail at the first railway site;

(b) a second field sensor system installed on the rail at a second railway site, where the second field sensor system is configured to collect data for use in calculating the neutral temperature of the rail at the second railway site, and where the second field sensor system collects a second set of data for use in calculating the neutral temperature of the rail at the second railway site;

(c) a wireless network for communicating data, including the data for use in calculating the neutral temperature of the rail at the first railway site and the data for use in calculating the neutral temperature of the rail at the second railway site; and

(d) an apparatus that is not located at the first railway site, and that evaluates the neutral temperature of the rail at the first railway site based on the first set of data collected at the first railway site.

9. The system of claim 8, where the apparatus determines whether the condition of the rail at the first railway site is potentially unsafe due to the potential of a rail break.

10. The system of claim 8, where the apparatus determines whether the condition of the rail at the second railway site is potentially unsafe due to the potential of a rail kink.

11. The system of claim 8, where the first field sensor system has been calibrated at the first railway site in connection with its installation at the railway site.

12. The system of claim 8, where the first field sensor system is installed at the first railway site through a process that includes determining the initial neutral temperature of the rail at the first railway site.

13. The system of claim 8, where the apparatus is configured to receive the first set of data and the second set of data using a vehicle traveling on the railway rail.

14. The system of claim 8, where the apparatus is configured to receive the first set of data and the second set of data without assistance from data collection personnel.

15. A system for monitoring the neutral temperature of a railway rail, the system comprising:

(a) a field sensor system that is calibrated and installed on a rail at a railway site, where the calibration includes determining the initial neutral temperature of the rail at the rail site, and where the field sensor system is configured to detect longitudinal strain on the rail,

where the field sensor system collects a first set of data relating to longitudinal strain on the rail at the railway site, and where the field sensor system later collects a second set of data relating to longitudinal strain on the rail at the railway site;

(b) a wireless network that communicates data from the field sensor system to a remote location; and

(c) an apparatus that is not located at the railway site, and that evaluates the neutral temperature of the rail at the railway site based on the first set of data relating to longitudinal strain on the rail at the railway site and the second set of data relating to longitudinal strain on the rail at the railway site,

where the apparatus is configured to receive the first set of data and the second set of data collected at the railway site without assistance from data collection personnel.

16. The system of claim 15, where the apparatus determines whether the condition of the rail at the railway site is unsafe due to the potential of a rail break.

17. The system of claim 15, where the apparatus determines whether the condition of the rail at the railway site is unsafe due to the potential of a rail kink.
