METHOD FOR REVEALING ERRORS IN A SIGNAL BOX COMPUTER SYSTEM, AND SIGNAL BOX COMPUTER SYSTEM

摘要

The invention relates to a method for revealing errors in a signal box computer system having at least one first computer channel (1a; 8) and at least one second computer channel (1b; 9), the input signals of which represent secure state indications of a railway safety system (2) in terms of signal technology and the output signals of which can be displayed on a display (7), and a signal box computer system for performing the method. In order to reduce the security specifications for the computer channels (1a; 8 and 1b; 9) and to improve the display convenience for a user, the output signals of the first computer channel (1a; 8), according to the invention, produce a state image (5a) and the output signals of the second computer channel (9) produce a risk analysis image (13) and the state image (6a) and the risk analysis image (13) can be superimposed on the display (7).
