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.
Claims18
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.
6 more elements
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.
2 more elements
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.
