Definitions

the present invention relates to a logic circuit and a method for replacing a positively driven safety relay by such a logic circuit, wherein the safety relay has a signal circuit contact, a normally closed contact with a ⁇ ffnereingang and a ⁇ ffnerausgang and a SchliesserCount with a Schliessereingang and a Schliesserausgang
a safety relay has three mutually mechanically connected switching contacts.
the actual make contact is a signal circuit contact that effectively ensures a function of a train protection or train steering device, such as the illumination of a signal lamp, the reversal of a switch and the like.
a train protection or train steering device such as the illumination of a signal lamp, the reversal of a switch and the like.
a normally closed contact which has a normally closed contact and a normally open output, is closed and thus shows a voltage, such as a supply voltage potential, in the energized state at the make contact output.
a safety device such as a relay fault.
a relay failure for example, the setting of a road is canceled or the road is on the driving in the field of view with regard to the displayed signal term down (for example, from GREEN to YELLOW).
the relay failure triggers an immediate disengagement of a service technician.
relay interlocking Even today, electrical relay systems in groups of relay relays combine to dominate the route networks of many European railways. These interlocking systems are referred to as relay interlocking. Since these interlocking systems will reach the end of their lifetime in the foreseeable future or because of the difficulties to secure the required know-how of the antiquated relay technology in the relay interlocking in the long term, they must be replaced by a new technology. Due to the fact that relay interlockings with the principle of positive-guided relay contacts (basic property of a safety relay) achieve a sufficiently high level of security, it makes sense in a partial or complete replacement of these relays to continue to consider these principles.
the present invention is therefore based on the object of providing a logic circuit and a method for replacing a safety relay, which maps the specific behavior of these safety relays correctly and timely in the logic.
the logic circuit and the method allow the mapping of a circuit of a safety relay in logic by the specific behavior of a safety relay, in particular given by the positively driven openers and closers of the contacts and by the timing behavior when the relay is applied and dropped.
This solution allows in particular, the adoption of the safety principles for the functions of switches, signals, track blocks, level crossing logic including free circuits), which are based on these relay interlockings.
the logic circuit and the method by means of a two-channel logic simulate the behavior of a safety relay, with both temporal and safety boundary conditions are adequately considered.
the figure shows a schematic view of the structure of the logic circuit 2, which can also be referred to below as FPGA relay 2, for replacing a safety relay.
FPGA relay 2 for replacing a safety relay.
Right in the picture is shown for direct comparison, a corresponding relay circuit 4 in Pfeilscher short circuit for a safety relay.
the embodiment described above describes the replacement of a safety relay in positive logic. If the safety relay would switch off the signal circuit contact when energized, the test of NC and NO contacts would have been performed in reverse order in the above procedure. Above to the normally closed contact would then apply to the close contact and vice versa.
the logic circuit 2 explained here can therefore replace a corresponding safety relay in a relay interlocking of conventional design. This has the great advantage that the relay interlocking can also be operated hybrid (ie with conventional safety relays and FPGA safety relays).
