Data Processing Device for a Parking System

A data processing device for a parking system, comprising:

• at least one receiving module configured to receive an entry data set containing an entry license plate string determined by a first license plate recognition equipment of a vehicle driving into a parking device of the parking system and at least one entry raw signal detected by an entry signal detection equipment in an entry area of the parking device during the driving in of the vehicle,
• at least one storage module configured to store the received entry data set in a data memory,
• wherein the receiving module is configured to receive an exit data set containing an exit license plate string determined by a second license plate recognition equipment of a vehicle driving out of the parking device and at least one exit raw signal detected by an exit signal detection equipment in an exit area of the parking device during the driving out of the vehicle, and
• at least one evaluation module configured to determine an entry data set corresponding to the received exit data set from the stored entry data sets by:
• comparing, in a first comparison step, the exit license plate string of the exit data set with the respective entry license plate strings of the stored entry data sets, and
• comparing, in a second comparison step, the at least one exit raw signal of the exit data set with the entry raw signal of the at least one entry data set of the stored entry data sets which contains the entry license plate string that is most similar to the exit license plate string of the exit data set.
