Abstract

A computerized parking system which includes a first camera for reading the license plate of a vehicle entering a parking area, and a second camera for reading the license plate of the vehicle as it leaves the parking area. In each instance, the letters and numbers on the license plate of each vehicle are converted into digital signals. The system responds to the digital signals from the cameras to determine the time of entry and time of exit of the vehicle, and the time vehicle remained in the parking area is then determined. The parking fee due for each vehicle is computed on the basis of a predetermined rate or rates and on the time in which the particular vehicle remained in the parking area. The system then produces a ticket, or a visual display, at a cashier'"'"'s station at the exit on which the amount to be paid is recorded, and when that amount is paid the cashier opens the gate. In the case of a monthly customer, the gate may be opened automatically as the particular vehicle reaches the exit gate, and the amount due for that vehicle is accumulated within the computer for monthly billing. The system may also be automatic for the daily customer, with a currency machine being provided which opens the exit gate when the proper parking fee has been inserted into the machine.

Claims

1. A system for detecting the time vehicles remain in a particular area, and area having an entrance and an exit, each of the vehicles being equiped with a license plate, said system including:

a first camera mounted at the enterance of the area positioned to be directed at the license plate of each vehicle entering the area;

a processing system connected to the camera for converting the indicia on the license plate as sensed by the camera into corresponding digital signals;

memory means included in the system for storing the aforesaid digital signals;

a second camera mounted at the exit of the area in position to be directed at the license plate of each vehicle leaving the area, said second camera being connected to said processing system to enable the processing system to convert the indicia on the license plate as sensed by the second camera into corresponding digital signals; and

computer means connected to the processing system including a logical clock for storing in the memory means signals representative of the time each vehicle entered the area as sensed by the first camera means and responding to the digital signals from said processing system representing indicia sensed by the second camera to determine the time each vehicle remained in the area.

2. The system defined in claim 1, in which said computer means includes means for computing the total fee due for each vehicle based on the time the vehicle remained in the area and a predetermined fee rate.

3. The system defined in claim 2, and which includes output means connected to the computer including display means located at the exit for displaying the fee due for each vehicle as the vehicle leaves the area.

4. The system defined in claim 3, in which said output means includes a printer located at the exit for printing a receipt on which the fee is imprinted.

5. The system defined in claim 2, in which said computer means includes memory means for storing signals representing accumulated fees for selected vehicles entering and leaving the area, and printer means connected to the computer means for providing periodic statements on which the accumulated fees are imprinted.

6. The system defined in claim 1, and which includes a gate included at said entrance, and means connecting said processing system to said gate to cause said gate to open when the indicia on the license plate of a vehicle is sensed by said first camera.

7. The system defined in claim 1, and which includes video monitor means connected to said first and second cameras for displaying the indicia of the license plate sensed thereby.

8. The system defined in claim 1, and which includes a gate located at said entrance, and a ticket dispenser located adjacent to said gate and connected to said processing system to cause said gate to open after the indicia on the license plate has been sensed and when a ticket is withdrawn from said dispenser and to cause data identifying the ticket to be stored in said memory means.

9. The system defined in claim 8, and which includes output means connected to said computer and including a printer located at said exit gate for receiving said ticket and for imprinting a receipt of the fee.

10. The system defined in claim 2, and which includes a gate located at said exit;

and automatic currency receiving means located at said gate and connected to said computer for causing said gate to open after the proper fee has been inserted into said receiving means.

11. The system defined in claim 1, and which includes a main frame computer located at a remote control center;

and a communication link connecting said main frame computer to said computer means.
