A method for error detection in the case of a interlocking computer system and interlocking computer system

摘要

The invention relates to a method for error detection in the case of a interlocking computer system with a control channel (1a; 8), the input signals to be signaling-technology safe status messages of a railway safety installation (2) and whose output signals for the operation of at least one element, for example a light signal, of the railway safety installation (2) are formed and on a display (7) as a text and graphic-color imaging (14) are displayed as well as a interlocking computer system for carrying out the method. In order to unnecessary pixel evaluations of the display (7), it is provided to avoid that, in the case of introduction of the operation of the element from element-specific pixel data of the display (7) by means of ocr – optical character recognition – encoded first text data (19) and with element-specific second text data (24) of a process image (23) of the status messages which is safe for signaling purposes are compared.
