Distributed positive train control system
First Claim
Patent Images
1. A system for controlling movement of a train in a track network, the system comprising:
- a central train control network;
a plurality of wayside controllers, each said wayside controller adapted to interface with the central train control network, and adapted to issue incremental movement authority to the train, wherein each said wayside controller issues incremental movement authority for only a designated section of said track network;
a data network switch coordinating a transition of the incremental movement authority between adjacent said wayside controllers when the incremental movement authority spans parts of more than one said designated section of said track network; and
a train data radio adapted to transmit train position information from the train to at least one of the wayside controllers.

Abstract
A system for controlling train movement uses a distributed architecture. Wayside controllers receive signals from individual trains, including position information derived from a navigation system. The wayside controllers interface with a central train control network, and coordinate local train movement including the issuance of incremental authorities.

14. A system for controlling movement of a train in a track network, the system comprising:
-
means for transmitting train position information from the train to at least one of a plurality of wayside controllers; means for interfacing between the wayside controllers and a central train control network; means for issuing incremental movement authority from one of the wayside controllers to the train, wherein each of the wayside controllers issues incremental movement authority for only a designated section of the track network; and means for coordinating a transition of the incremental movement authority from one of said wayside controllers to another of said wayside controllers when the incremental movement authority spans parts of more than one said designated section of said track network. - View Dependent Claims (15, 16, 17)

18. A method for controlling movement of a train in a track network, the method comprising:
-
transmitting train position information from the train to at least one of a plurality of wayside controllers; interfacing between the wayside controllers and a central train control network; issuing incremental movement authority from one of the wayside controllers to the train, wherein each of the wayside controllers issues incremental movement authority for only a designated section of the track network; and coordinating a transition of the incremental movement authority between adjacent wayside controllers when the incremental movement authority spans parts of more than one said designated section of said track network. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
