Process and system for detecting a particular state of a specific parking space
First Claim
1. A method for detecting a particular state of a specific parking space among a plurality of parking spaces, the particular state of the specific parking space being one of empty or occupied, each parking space being equipped with at least one detector for measuring a value of at least one parameter, said value being a magnetic field value, the at least one parameter being variable according to a presence or absence of a vehicle in the respective parking space, the method comprising steps of:
- measuring, during a first time interval, a first value of the magnetic field with the at least one detector associated with the specific parking space;
measuring, during said first time interval, a second value of the magnetic field with the at least one detector associated with at least one parking space close to the specific parking space, wherein the at least one parking space is considered close to the specific parking space if a presence or absence of a vehicle in the close parking space influences the first value of the magnetic field in a non-negligible way;
transmitting at least the first and second magnetic field values to a processing unit of a management center;
comparing, by the processing unit of the management center, the first magnetic field value with a stored reference value corresponding to a known state of the specific parking space;
comparing at least the second magnetic field value with the first magnetic field value; and
determining whether the specific parking space has an occupied or empty state, based on the result of both of said comparison steps.

Abstract
The present invention concerns a process and a system for detecting a particular state of a specific parking space among a plurality of parking spaces, a particular state being one of empty or occupied. Each parking space is equipped with at least one detector for measuring a value of at least one parameter, said parameter being variable according to the presence or absence of a vehicle.

7. A system for detecting a particular state of a specific parking space among a plurality of parking spaces, the particular state being one of empty or occupied, said system comprising:
-
a processing unit for a management center; and for each parking space, at least one detector configured to; measure a value of at least one parameter, said value being a magnetic field value, the at least one parameter being variable according to a presence or absence of a vehicle in the respective parking space, wherein the at least one detector for the specific parking space is configured to measure, during a first time interval, a first magnetic field value of the at least one parameter for the specific parking space; and transmit the measured magnetic field value from each detector to the processing unit of the management center; wherein the processing unit is configured to; compare the first magnetic field value with a stored reference value corresponding to a known state of the specific parking space; compare the first magnetic field value with a second value of the magnetic field of the at least one parameter measured, during the first time interval, for at least one parking space close to the specific parking space, wherein the at least one parking space is considered as close to the specific parking space if a presence or absence of a vehicle in the close parking space influences the first magnetic field value of the at least one parameter in a non-negligible way; and determine the particular state of the parking space based on the result of both of the comparison between the first magnetic field value and the stored reference value and the comparison between the first magnetic field value and the second magnetic field value. - View Dependent Claims (8, 9, 10, 11, 12, 13)
