摘要:
Embodiments relate to a transmitter (10, 54, 56) and/or a receiver (18, 60) for a system for detecting an event that is triggered by an object (12) crossing over a monitored line (14). The transmitter (10, 54, 56) is designed to successively send data packets (16) independently of an occurrence of the event. The receiver (18, 60) is designed to receive successive data packets (16) independently of the occurrence of the event. Each of the data packets (16) comprises information on a number (E1) of events that occurred up to a transmission time (T n ) of the data packet, wherein the transmission times (T n ) of successive data packets (16) each lie within a predetermined transmission period (T Window ).
