Classification: CPC G | IPC G

Claim 15:
16. A system having a plurality of vehicles that are in particular rail-bound and that each have at least one distance measuring optoelectronic and at least one target object, wherein the mutual positions of the vehicles are recognized with reference to the detection of the target objects by the distance measuring optoelectronic sensors to avoid accidents, the distance measuring optoelectronic sensor comprising:
a light transmitter for transmitting light pulses;
a deflection unit for a periodic scanning of the monitored zone by the light pulses;
a light receiver for generating a received signal from the light pulses reflected or remitted by objects in the monitored zone; and
a control and evaluation unit that is configured to determine a distance of an object from a time of flight of a light pulse and to transmit light pulses of different intensity,
wherein, for the detection of a target object having a specific reflection capability, the control and evaluation unit is further configured to transmit light pulses adapted to the reflection capability of the target object and to a distance range and to correspondingly vary the light pulses in accordance with different distance ranges to distinguish between the target object and another object, and
wherein the control and evaluation unit is further configured to increase the intensity of the light pulses toward large and very small ranges.
