Rail collision threat detection system
First Claim
Patent Images
1. A detection system comprising:
- a transmitter associated with a first train and configured to emit an end-of-train signal; and
a receiver associated with the transmitter and the first train and configured to;
receive the end-of-train signal from the transmitter;
receive at least one remote signal from a second train;
detect a signal strength of the remote signal;
determine a relative distance of the second train from the first train based on the signal strength of the remote signal; and
determine whether the second train is a collision threat to the first train based on the remote signal from the second train.

Abstract
A detection system may include a transmitter associated with a first train configured to emit an end-of-train signal. The detection system may include a receiver associated with the transmitter and configured to receive the end-of-train signal from the transmitter. The receiver may also be configured to receive at least one remote signal from a second train and determine whether the second train is a collision threat based on the remote signal from the second train.

7. A method for detecting a collision threat between a first train and a second train comprising:
-
receiving on the first train a signal from the second train; detecting a signal strength of the signal; determining a relative distance between the first train and the second train based on the signal strength; and identifying whether the second train is a collision threat to the first train based on the relative distance. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A first train comprising:
-
a locomotive; a transmitter associated with at least one of the locomotive and a trailing railcar and configured to emit an end-of-train signal; and a receiver associated with the locomotive and configured to; receive the end-of-train signal from the transmitter; receive a remote signal from a second train; detect a signal strength of the remote signal; determine a relative distance of the second train from the first train based on the signal strength of the remote signal; and determine whether the second train poses a collision threat to the first train based on the remote signal. - View Dependent Claims (15, 16, 17, 18)
