Brake control system for doubled ended locomotive

摘要

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.
