Traffic signalling module, traffic signalling system and method for the operation of a traffic signalling system

摘要

The present invention relates to a traffic signalling module (10a, 10b) with a signal giving device (11a, 11b), a driver unit (12a, 12b) for the signal giving device (11a, 11b) and a network - interface (14a, 14b) for communication with a number of further traffic signalling modules (10b, 10a) via a communication network (2). The traffic signalling module (10a, 10b) also has a safety control unit (15a, 15b), in order to return the operation of at least one other hand, on the communications network (2) connected traffic signalling module (10b, 10a) and to monitor according to a predetermined safety rule (sr), as a function of an erroneous operating state of the other traffic signalling module (10b, 10a) for a specific operation of the own signal giving device (11a, 11b) to ensure. In addition, a traffic signalling system (1) having a plurality of such traffic is arranged at different positions traffic signalling modules (10a, 10b) and a corresponding method for operation of a traffic signalling system (1) described.
