Fail-safe displaying method of traffic technical information for a traffic route system

摘要

Data (7) relating to the operating states of individual components (1a, 1b, 1c, 2) are output by an operating control device (4), in particular by an interlocking cabin. The elements (1a, 1b, 1c,) are assigned symbols (10, 11, 12) composed respectively of individual pixels, the pixels of a symbol (10) being in each case assigned the same colour values in accordance with the operating state-specific, current data (7) for the corresponding element (1a). The symbols are represented in full-graphic fashion pixel by pixel on a display device (25). In a first test routine, the colour value of a selected pixel (13) of a symbol (10) to be tested is read out and compared with the item of data (7) for the respective element (1a) and in the event of nonidentity a fault report (26) is generated.
