Method for fault disclosure in interlocking computer system with control channel, involves comparing pixel data of display with process data of process image of state information of reference system for display-protection

摘要

The method involves comparing an element specific pixel data of a display (8) with element-specific process data of a process image (29) of the signal technically-safe state information of a reference system (10) for display-protection. The reference system has a read-back channel (18) for reading back element-specific pixel data to the elements of the display and a logic channel (24) for generating and storing element-specific process data of the process image of the state information of a railroad protection system (2). An independent claim is included for an interlocking computer system with a source of messages.
