DATA PROCESSING DEVICE FOR AHEAD FREE WAY AVAILABILITY AT RAILWAY BLOCK-SECTIONS IN LOCOMOTIVE CONTROL SYSTEM ENSURING ROLLING STOCK SAFETY, AND PROCESS OF DATA TRANSFER TO SIGNAL SELECTION BOXES AND SIGNAL TRANSFER TO LOCOMOTIVE STOPLIGHT Russian patent published in 2008 - IPC B61L3/20 B61L25/00 

FIELD: automation.

SUBSTANCE: group of inventions concerns railway automation and can be applied in automated locomotive control system. The device consists of three decoders (1), (2), (3), two signal selection boxes (4) and (5), signal displaying devices (6) containing two signal initiating boxes (7) and (8), and stoplight (9); besides, the device includes two feedback blocks (10) and (11), and data transfer buses (B1-B10). Data is transferred to the signal selection boxes of data processing device ensuring rolling stock safety by inversion of parallel bus state, digital capacity of which is relevant to the messages transferred. The code is transferred by cycling of direct and inverted bus state; at that, in the direct bus state its digital capacity related to the transferred message is brought to high level, while the rest of the capacities are brought into low level; in the inverted bus state - vice versa. The signal is transferred to the locomotive stoplight by issuing current information signal from the information source to the relevant information light indicator. The signal is transferred to the locomotive light by two peer function signal initiating boxes, while transfer of information signal to the relevant information light indicator from one box is alternated with sending of diagnostic signal to the other indicators.

EFFECT: higher reliability due to fail tolerance.
