Process for monitoring the functioning and/or adjustment of an optoelectronic sensor arrangement, as well as an optoelectronic sensor arrangement

摘要

Monitoring the functioning and/or adjustment of an optoelectronic sensor arrangement (10) exhibiting at least two optical transmitters (S1, S2, S3), to each of which a laterally-resolving optical receiver is assigned, such that each of the optical transmitters (S1, S2, S3) and the corresponding optical receivers (E1, E2, E3) are so positioned relative to each other that a light ray (L1a, L2a, L3a) emitted from the optical transmitter (S1, S2, S3) can be detected by the corresponding optical receiver (E1, E2, E3) after being reflected by a boundary surface (F), which process involves the following steps:a) detecting the current position-proportional reception values for each optical transmitter (S1, S2, S3) and corresponding optical receiver (E1, E2, E3),b) determining the current relative positions for the reception values of any two adjacent optical transmitters (S1, S2, S3), p0 c) comparing the current relative positions for the reception values with stored reference values.
