Train Detection System and Method of Detecting Train Movement and Location
First Claim
1. A train detection system for detecting a train unit, comprising:
- a first transponder interrogator configured to generate one or more request signals for transmission, by a first antenna above a first track location, toward a first fixed transponder at the first track location;
a second transponder interrogator configured to generate one or more request signals for transmission, by a second antenna above a second track location, toward a second fixed transponder at the second track location; and
a controller communicably connected with the first and second transponder interrogators and configured to verify operation of the train detection system based on receipt of one or more message signals responsive to transmission of the one or more request signals from the first and second transponder interrogators.

Abstract
A train detection system for detecting a train unit that includes a first transponder interrogator configured to generate one or more request signals for transmission, by a first antenna above a first track location, toward a first fixed transponder at the first track location; a second transponder interrogator configured to generate one or more request signals for transmission, by a second antenna above a second track location, toward a second fixed transponder at the second track location; and a controller communicably connected with the first and second transponder interrogators and configured to verify operation of the train detection system based on receipt of one or more message signals responsive to transmission of the one or more request signals from the first and second transponder interrogators.

13. A train detection system, comprising:
-
at least a first mobile transponder and a second mobile transponder mounted at opposite ends on a train unit; a first fixed transponder and a second fixed transponder mounted at first and second track locations; a first antenna and a second antenna above corresponding first and second track locations; a first transponder interrogator configured to generate one or more request signals for transmission, by the first antenna above the first track location, toward the first fixed transponder at the first track location; a second transponder interrogator configured to generate one or more request signals for transmission, by the second antenna above the second track location, toward the second fixed transponder at the second track location; and a controller communicably connected with the first and second transponder interrogators and configured to verify operation of the train detection system based on receipt of one or more message signals responsive to transmission of the one or more request signals from the first and second transponder interrogators. - View Dependent Claims (14)

15. A method of detecting train movement and location of a train unit having first and second mobile transponders mounted thereon using a train detection system, the method comprising:
-
scanning, via a first transponder interrogator, first fixed transponders at first and second track locations in a first predetermined order, using a first antenna above each first and second track location, and scanning, via a second transponder interrogator, second fixed transponders at first and second track locations in a second predetermined order, using second antenna above each first and second track location; and verifying, via a controller operation of the train detection system based on the scanning. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A method of detecting train movement and location of a train unit having first and second mobile transponders mounted thereon using a train detection system, the method comprising:
-
scanning, via a first transponder interrogator and a second transponder interrogator, first and second fixed transponders at a specified track location; scanning, via the first and second transponder interrogators, first and second mobile transponders of the train unit and communicating between a controller of the train detection system and an on-board controller of the train unit, if the train unit arrives at the specific track location; and verifying, via the controller, a location of the train unit at the specified track location based on the scanning of the first and second mobile transponders. - View Dependent Claims (29, 30, 31)
