RFID based parking management system
First Claim
Patent Images
1. A radio frequency identification (RFID) based parking system to control at least one gate configured to allow a patron in a vehicle to enter or exit a parking facility without stopping, the system comprising:
- a first antenna configured to read a passive RFID tag in a first area within a lane associated with an entrance or an exit of the parking facility, wherein the first antenna and the corresponding first area are positioned to minimize false readings of RFID tags of other vehicles entering or exiting the parking facility and to allow the vehicle to enter or exit the parking facility without stopping;
a second antenna configured to read the passive RFID tag in a second area, separate from the first area, contained within the lane associated with the entrance or exit, wherein the second antenna and the corresponding second area are positioned to read the passive RFID tag when the first antenna fails to read the RFID tag to allow the vehicle to enter or exit the parking facility;
a first detector to detect the vehicle entering the first area;
a second detector to detect the vehicle entering the first area;
a passive RFID reader connected to the first and second antennae configured to sequentially activate the first antenna when the vehicle enters the first area and deactivate the first antenna and activate the second antenna when the vehicle enters the second area to read an identification (ID) associated with the passive RFID tag when the passive RFID tag passes through one of the first and second areas to allow the vehicle to enter or exit the parking facility without stopping;
a processing device configured to determine that the read ID is valid and may access the facility and configured to control the gate to open;
wherein D, a distance in feet along a horizontal axis from the gate to an edge of the first area farthest from the gate, is selected to allow the vehicle to enter or exit the parking facility without stopping and is determined as the sum of D1 the distance in feet along the horizontal axis from the gate to the second detector and D2 the distance in feet along the same horizontal axis from the second detector to the first detector and D is expressed as;
D=D1+D2=2×
MPH+(MPH)2/5 where MPH is the speed limit in miles per hour in the lane at the gate.

Abstract
An radio frequency identification (RFID) tag parking system to control a gate to allow a patron in a vehicle to enter and exit a parking facility without stopping, the system comprising: a first antenna for reading an RFID tag in a first area contained within a lane 215 associated with an entrance or an exit of the facility; a second antenna for reading the RFID tag in a second area, separate from the first area, contained within the lane 215 associated with the entrance or exit; an RFID reader 250 connected to the first and second antennae to read an identification (ID) associated with the RFID tag when the RFID tag passes through one of the first and second areas; and a processing device to determine that the read ID is valid and may access the facility and to control the gate to open. The system of claim 1 wherein the first and second antennae are sequentially activated as a vehicle enters the first area and the second area, respectively. The system also may include a registration unit 120, a payment unit, a driver information unit, and a reservation unit.
