Abstract

A system and method for examining a route and/or vehicle system obtain a route parameter and/or a vehicle parameter from discrete examinations of the route and/or the vehicle system. The route parameter is indicative of a health of the route over which the vehicle system travels. The vehicle parameter is indicative of a health of the vehicle system. The discrete examinations of the route and/or the vehicle system are separated from each other by location and/or time. The route parameter and/or the vehicle parameter are examined to determine whether the route and/or the vehicle system is damaged and, responsive to determining that the route and/or the vehicle is damaged, the route and/or the vehicle system are continually monitored, such as by examination equipment onboard the vehicle system.

First claim

What is claimed is:

1 . A system comprising:
a controller configured to obtain one or more of a route parameter or a vehicle parameter from discrete examinations of one or more of a route or a vehicle system, the route parameter indicative of a health of the route over which the vehicle system travels, the vehicle parameter indicative of a health of the vehicle system, the discrete examinations of the one or more of the route or the vehicle system separated from each other by one or more of location or time, the controller configured to examine the one or more of the route parameter or the vehicle parameter to determine whether the one or more of the route or the vehicle system is damaged; and examination equipment configured to continually monitor the one or more of the route or the vehicle system responsive to determining that the one or more of the route or the vehicle is damaged.

2 . The system of claim 1 , wherein the controller is operable to receive at least a portion of the one or more of the route parameter or the vehicle parameter from a stationary wayside unit disposed alongside the route being traveled by the vehicle system.

3 . The system of claim 2 , wherein the controller is operable to receive the at least the portion of the one or more of the route parameter or the vehicle parameter from the wayside unit that includes information relating to whether there is a problem or potential problem with a wheel of the vehicle system.

4 . The system of claim 1 , wherein the controller is operable to switch operating modes of the vehicle system based on at least one of the one or more of the route parameter or the vehicle parameter from the discrete examinations or information communicated from the examination equipment from continually monitoring the one or more of the route or the vehicle system.

5 . The system of claim 4 , wherein at least one of the operating modes comprises the controller slowing or stopping movement of the vehicle system.

6 . The system of claim 4 , wherein at least one of the operating modes comprises the controller monitoring the vehicle system for one or more indications that a wheel is exhibiting a problem with the vehicle system.

7 . The system of claim 1 , wherein the controller is operable to receive the one or more of the route parameter or the vehicle parameter as information that is one or both of geographically discrete or temporally discrete.

8 . The system of claim 1 , wherein the examination equipment includes one or more of an asset health monitor or a broken rail detector.

9 . The system of claim 1 , wherein the controller is configured to prevent or reduce a probability of occurrence of a derailment of the vehicle system due to at least one of a broken wheel, a locked axle, or a broken rail based on the one or more of the route parameter or the vehicle parameter received from the discrete examinations and information received from the examination equipment relative to the controller not receiving the one or more of the route parameter or the vehicle parameter and the information from the examination equipment.

10 . A method comprising:
obtaining one or more of a route parameter or a vehicle parameter from discrete examinations of one or more of a route or a vehicle system, the route parameter indicative of a health of the route over which the vehicle system travels, the vehicle parameter indicative of a health of the vehicle system, the discrete examinations of the one or more of the route or the vehicle system separated from each other by one or more of location or time; examining the one or more of the route parameter or the vehicle parameter to determine whether the one or more of the route or the vehicle system is damaged; and responsive to determining that the one or more of the route or the vehicle is damaged, continually monitoring the one or more of the route or the vehicle system.

11 . The method of claim 10 , wherein the one or more of the route parameter or the vehicle parameter is obtained from a stationary wayside unit disposed along the route.

12 . The method of claim 10 , wherein continually monitoring the one or more of the route or the vehicle system includes continually monitoring the one or more of the route parameter or the vehicle parameter from examination equipment disposed onboard the vehicle system.

13 . The method of claim 10 , wherein continually monitoring the one or more of the route or the vehicle system occurs between plural discrete examinations of the one or more of the route or the vehicle system.

14 . The method of claim 13 , wherein the plural discrete examinations of the one or more of the route or the vehicle system one or more of occur during different, non-overlapping time periods or occur at different locations, with the continually monitoring of the one or more of the route or the vehicle system occurring one or more of between the different, non-overlapping time periods or between the different locations.

15 . The method of claim 10 , further comprising, responsive to determining that the one or more of the route or the vehicle system is damaged based on continually monitoring the one or more of the route or the vehicle system, implementing a control action, the control action including one or more of automatically slowing or stopping movement of the vehicle system, automatically requesting inspection, repair, or maintenance of the one or more of the route or the vehicle system, applying an adhesion-modifying substance to the route, preventing application of the adhesion-modifying substance to the route, lifting one or more axles of the vehicle system away from the route, or lowering the one or more axles of the vehicle system toward the route.

16 . The method of claim 10 , wherein:
both the route parameter and the vehicle parameter are obtained from the discrete examinations of the route and the vehicle system, respectively; the route parameter and the vehicle parameter are examined to determine whether the route or the vehicle system is damaged, respectively; the one or more of the route or the vehicle system are continually monitored, responsive to the determining damage of the one or more of the route or the vehicle, to at least one of confirm or quantify the damage; and the method further comprises controlling the vehicle system responsive to the damage that is at least one of confirmed or quantified.

17 . The method of claim 16 , wherein at least one of the route parameter or the vehicle parameter is obtained from a stationary wayside unit disposed along the route, and wherein continually monitoring the one or more of the route or the vehicle system includes continually monitoring the one or more of the route parameter or the vehicle parameter from examination equipment disposed onboard the vehicle system.

18 . A system comprising:
one or more processors configured to obtain one or more of a route parameter or a vehicle parameter from discrete examinations of one or more of a route or a vehicle system, the route parameter indicative of a health of the route over which the vehicle system travels, the vehicle parameter indicative of a health of the vehicle system, the one or more processors also configured to examine the one or more of the route parameter or the vehicle parameter to determine whether the one or more of the route or the vehicle system is damaged; and examination equipment configured to continually monitor the one or more of the route or the vehicle system responsive to the one or more processors determining that the one o
