Method and system for automatically detecting and checking the use of parking places of a parking arrangement, which is provided with a parking network and a central computer, the parking places being each provided with an electronic parking sensor module, which has an identification code and a vehicle sensor for detecting vehicles in the respective parking places, wherein use is made of electronic license devices, carried along with the vehicles and each having a unique identification number and motion sensor means, which can determine at what time a vehicle comes to a standstill, and wherein information about said time together with the identification number is transmitted to the central computer, which can compare said time with times at which the parking places become occupied, to determine in which parking place the vehicle is parked.

Method and system for automatically detecting and checking parking places of a parking arrangement

Parking arrangement and method for making a parking arrangement equipped with an automatic vehicle detection system ready for operation, which parking arrangement comprises a central computer with a database and at least a number of parking places identifiable by a location code, which parking places are each provided with at least one wirelessly operating parking sensor module, which is connected with the central computer via a UHF radio link and which is provided with an identification code, which parking sensor module comprises at least one vehicle sensor which in operation provides measuring values representative of the presence or absence of a vehicle in the respective parking place, wherein use is made of parking sensor modules which have an RFID identification circuit in which the identification code is stored, which identification code is wirelessly readable.

Method for making a parking arrangement equipped with an automatic vehicle detection system ready for operation, and parking arrangement for use of the method

A parking arrangement with parking places for vehicles and with an automatic vehicle detection system which comprises a central computer system and a wirelessly operating parking sensor module for determining the presence or absence of a vehicle in the parking place, which parking sensor module comprises at least one vehicle sensor, which provides measuring values which are representative of the presence or absence of a vehicle, provided with calibration means for determining the quiescent value, representing the absence of a vehicle, of the measuring values from the vehicle sensor, which calibration means by a self-organizing map method divide the measuring values into clusters of mutually close values, wherein the cluster having the largest number of measuring values is selected as representative of the quiescent value of the measuring values at a parking place, wherein each time an adjusted quiescent value is determined, and wherein a measuring value which differs from the quiescent value by more than a predetermined threshold value indicates that a vehicle is situated in the parking place.
