ABSTRACT:
A circuit arrangement for monitoring the state of signal systems, particularly traffic light systems monitors different signal states as to the admissability or inadmissibility thereof in a simple manner without the necessity of carrying out manual wiring manipulations given a change of the signal conditions in adaptation to changed conditions or given an expansion of the signal system to be monitored. For this purpose, test signals which indicate test signal states are fixed in a memory and are processed with the signals indicating the respectively existing actual signal state of the signal transmitters in at least one microprocessor in such a manner that each signal indicating an actual state is compared with all test signals which are called up step-by-step in succession from the memory.
