Brake control system for doubled ended locomotive
First Claim
1. A system for electronically controlling brakes on a train through a double ended locomotive, said system comprising:
- (a) a first cab station means for generating a first stream of signal packets indicative of parameters for operating said system;
(b) a second cab station means for generating a second stream of signal packets indicative of parameters for operating said system; and
(c) a brake control means, communicating with said first and said second cab station means, for selecting which one of said cab station means will direct control of such brakes and for controlling operation of such brakes in response to at least said stream of signal packets corresponding to said cab station means so selected.

Abstract
A system for electronically controlling brakes on a train through a double ended locomotive is disclosed. The electronic brake control system comprises a first cab station, a second cab station and a brake control device which communicates with each of the cab stations. The cab stations are interchangeable and operate in part according to algorithms set forth in software written for the instant cab stations. The brake control device likewise operates in part according to algorithms set forth in software written for the brake control device. The first cab station generates a first stream of signal packets indicative of parameters for operating the system and transmits same to the brake control device. The second cab station likewise generates a second stream of signal packets indicative of parameters for operating the system and transmits same to the brake control device. Each cab station generates and transmits its respective stream of signal packets one signal packet at a time. From these signal packets, the brake control device determines which of the cab stations will direct control of the train brakes according to basic rules set forth in the software. When the brake control device selects one of said cab stations to direct control of the brakes, the brake control device controls operation of the brakes in response to at least the stream of signal packets corresponding to the selected cab station.

18. A cab control unit for use with a system for electronically controlling brakes on a train through a double ended locomotive, said cab control unit comprising:
-
a) a cab I/O card for receiving electrical signals indicative of position of a brake handle and indicative of a request for a mode of operation of such system; and b) a cab CPU board for generating a stream of signal packets at least in part from such electrical signals received by said cab I/O card and for communicating said stream of signal packets to a means for controlling such brakes and for receiving and processing commands from such brake control means pertaining to whether such request for a change of such mode is granted or denied.

19. A brake control unit for use with a system for electronically controlling brakes on a train through a double ended locomotive, said brake control unit comprising:
-
(a) a brake CPU board interconnected to a pair of cab control units each of which generates a stream of signal packets indicative of at least a position of a brake handle and a request for a mode of operation of such system; and (b) at least one brake I/O card interconnected to said brake CPU board and through which control of such brakes is effected;
wherein said brake CPU board is for selecting which one of such streams of signal packets will be used to direct control of such brakes and for so controlling operation of such brakes through said at least one brake I/O card in response to at least such stream of signal packets so selected. - View Dependent Claims (20)
