Device to monitor occupancy of designated parking spaces has sensor unit arranged above designated spaces with laser beam transmitter and detector to monitor presence of vehicles in spaces

摘要

The device has a sensor unit arranged above the designated spaces (5), which has a transmitter and detector to monitor the presence of vehicles in the spaces. The sensor unit has at least one transmitter that transmits at least one rotating laser pulse, which generates beam paths that extend parallel to the rows (3,4) of spaces. The sensor unit has an evaluation unit that evaluates the detector data to produce a profile of the meeting points of the beam paths and assigns individual groups of spatially determined objects.
