Abstract

A system and method for collecting and delivering operational data relating to railroad grade crossing equipment and wayside equipment is described. The method comprises collecting operational data relating to railroad crossing equipment and wayside equipment in a data server, receiving the operational data from the data server with a data delivery device when the data server is in proximity to the data delivery device, and transmitting the operational data from the data delivery device to an external communication system.

Claims

1. A method for delivery of railroad crossing and wayside equipment operational data, said method comprising:

collecting operational data relating to railroad crossing equipment and wayside equipment in a data server;

receiving the operational data from the data server with a data delivery device when the data server is in proximity to the data delivery device; and

transmitting the operational data from the data delivery device to an external communication system.

2. A method in accordance with claim 1 wherein collecting operational data comprises organizing the operational data into operational data files.

3. A method in accordance with claim 2 further comprising encoding in each operational data file a data field that indicates what portions of the file have been successfully delivered from the data server to the external communication system in a fragmented form.

4. A method in accordance with claim 1 wherein the step of receiving the operational data from the data server with a data delivery device further comprises configuring a train with the data delivery device.

5. A method in accordance with claim 1 wherein said step of transmitting the operational data from the data delivery device to an external communication system comprises transmitting the operational data to at least one of a computer system attached to the data delivery device and a reception point in proximity to the data delivery device.

6. A method in accordance with claim 5 wherein transmitting the operational data to a reception point in proximity to the data delivery device further comprises transmitting the operational data from the reception point to the computer system, the computer system communicatively coupled to a database.

7. A method in accordance with claim 1 wherein said step of receiving the operational data from the data server with the data delivery device when the data server is in proximity to the data delivery device comprises the step of determining proximity by at least one of continuous or periodic radio polling by the data server, continuous or periodic radio polling by the data delivery device, reception of a head-of-train transponder by the data server, detection of an audible horn signal of the approaching locomotive, and detection of crossing activation signal from the crossing controller equipment.

8. A method in accordance with claim 5 wherein transmitting the operational data to a reception point comprises the step of determining proximity by at least one of continuous or periodic radio polling by the data server, continuous or periodic radio polling by the data delivery device, reception of a head-of-train transponder by the data server, detection of an audible horn signal of the approaching locomotive, and detection of crossing activation signal from the crossing controller equipment.

9. A method in accordance with claim 2 wherein the step of transmitting the operational data from the data delivery device to at least one of a computer system and a reception point, wherein the computer system is configured for one or more of parsing all operational data, associating operational data files and file fragments with particular remote sites, eliminating redundant files or fragments, resolving any errors, and reconstructing the original operational data files from each of the remote sites that include a data server.

11. A system for delivering railroad crossing and wayside equipment operational data, said system comprising:

at least one data server configured to;

collect operational data relating to railroad crossing equipment and wayside equipment;

configure the operational data into operational data files; and

transmit the operational data files;

at least one data delivery device configured to;

receive the operational data files from said data server when said data server is in proximity to said data delivery device; and

transmit the operational data files; and

an external communication system comprising at least one of a computer system attached to said data delivery device and a reception point in proximity to said data delivery device, said reception point communicatively coupled to a computer system, said external communication system configured to;

receive the operational data files; and

store the operational data files in a database.

10. A method in accordance with claim 11 wherein receiving the operational data from the data server with a data delivery device when the data server is in proximity to the data delivery device comprises:

mounting the data delivery device at an end of a train;

receiving, at the data server, a notification from grade crossing equipment or wayside equipment that the last car of a train has passed, signifying that the data delivery device is in a position to receive operational data from the data server; and

transmitting the operational data from the data server to the data delivery device.

12. A system in accordance with claim 11 wherein said data server is further configured to encode each operational data file with a data field that indicates what portions of the operational data files have been successfully delivered from said data server to said external communication system in a fragmented form.

13. A system in accordance with claim 11 wherein said data delivery device is mounted on a train.

14. A system in accordance with claim 13 wherein said reception point is further configured to:

receive the operational data files from said data delivery device when said data delivery device is in proximity to the reception point; and

transmit the operational data to said computer system.

15. A system in accordance with claim 11 wherein said data delivery device is further configured to transmit the operational data utilizing at least one of wireless data communication and hardwire data communication.

16. A system in accordance with claim 11 wherein one or more of said data server, said data delivery device, and said reception point are further configured to determine proximity by at least one of continuous or periodic radio polling by said data server, continuous or periodic radio polling by said data delivery device, reception of a head-of-train transponder by said data server, detection of an audible horn signal of the approaching locomotive, and detection of crossing activation signal from the crossing controller equipment.

17. A system in accordance with claim 11 wherein said computer system is further configured for one or more of parsing all operational data, associating operational data files and file fragments with particular remote sites, eliminating redundant files or fragments, resolving any errors, and reconstructing the original operational data files from each of the remote sites that include one of said data servers.

18. A system in accordance with claim 11 wherein said data delivery device and said data server utilize a spread spectrum radio link or a short range RF data network, allowing authentication of each operational data file or portion of an operational data file received by said data delivery device.

19. A system in accordance with claim 11 wherein said data delivery device is mounted on at an end of a train and powered by an end of train device.

20. A system in accordance with claim 19 wherein said data server is configured to be notified by grade crossing equipment and wayside equipment that the last car of a train has passed, signifying that said data delivery device is in a position to receive operational data files from said data server.
