Vehicle and route monitoring system
A system is provided that may include a controller having one or more processors. The one or more processors may control movement of a vehicle system along a route, and determine a restriction in speed of the vehicle system at a switch point. The one or more processors may determine a direction of movement of the vehicle system based on the restriction in the speed at the switch point.
1. A system comprising:
a controller having one or more processors configured to:
control movement of a vehicle system along a route;
determine a change in speed of the vehicle system at a switch point; and
determine a switch type at the switch point based on the change in the speed at the switch point.
2. The system of claim 1 , wherein the one or more processors are further configured to compare the change in the speed of the vehicle system to determined speeds related to switch types.
3. The system of claim 1 , wherein the one or more processors are configured to determine the switch type based on at least one of (a) a frog angle or (b) a distance of the route between the switch point and a half point of the frog angle.
4. The system of claim 1 , wherein the one or more processors are further configured to:
populate a map at the switch point with the switch type that is determined.
5. The system of claim 1 , wherein the one or more processors are further configured to communicate the switch type that is determined to a remote controller.
6. The system of claim 1 , wherein the vehicle system is a rail vehicle.
7. The system of claim 1 , wherein the one or more processors are further configured to restrict the movement of the vehicle system based on communications from a positive vehicle controller.
8. The system of claim 1 , wherein the one or more processors are further configured to adjust a vehicle control setting based on the switch type.
9. The system of claim 8 , wherein the vehicle control setting comprises at least one of a throttle setting or a dynamic braking setting.
10. A method comprising:
receiving, with a vehicle controller, communication from a positive vehicle controller at a remote location;
determining a change in speed of a vehicle system at a switch point on a route based on the communication from the positive vehicle controller; and
determining a direction of movement of the vehicle system at the switch point based on the change in the speed at the switch point.
11. The method of claim 10 , wherein determining the direction of the movement of the vehicle system at the switch point includes comparing the change in the speed of the vehicle system to determined speeds related to switch types.
12. The method of claim 10 , further comprising:
determining, with the vehicle controller, a location of the switch point based on the communication from the positive vehicle controller.
13. The method of claim 12 , further comprising:
determining a switch type based on the change in the speed of the vehicle system at the switch point.
14. The method of claim 13 , wherein determining the switch type includes obtaining, with the vehicle controller, at least one of (a) a frog angle or (b) a distance of the route between the switch point and a half point of the frog angle.
15. The method of claim 14 , further comprising communicating the switch type from the vehicle controller to the positive vehicle controller for populating a map that includes the route.
16. A system comprising:
a vehicle system with a vehicle controller having one or more processors configured to:
receive communications from a positive vehicle controller remote from the vehicle system related to a change in speed of the vehicle system;
obtain the change in the speed of the vehicle system at a determined location on a route; and
determine a switch type at a switch point at the determined location based on the change in the speed at the determined location on the route.
17. The system of claim 16 , wherein the determined location is a switch point location between a normal leg of the route and a reverse leg of the route.
18. The system of claim 16 , wherein the one or more processors are further configured to:
compare the change in the speed of the vehicle system to determined speeds related to switch types.
19. The system of claim 18 , wherein the switch type is based on at least one of (a) a frog angle or (b) a distance of the route between a switch point and a half point of the frog angle.
20. The system of claim 18 , wherein the one or more processors are further configured to communicate the switch type determined to the positive vehicle controller.
21. The system of claim 16 , wherein the one or more processors are further configured to restrict movement of the vehicle system based on the communications from the positive vehicle controller.
