Abstract

A system for collecting a toll for a vehicle, on which a vehicle number plate is mounted, is disclosed. In the system, a radio card as a storage medium is provided in the vehicle. The radio card generates a data signal representing a identification data including a vehicle number data. A radio card access system receives the data signal transmitted from the radio card and processes the data signal to obtain the vehicle number data contained in the radio card. A TV camera picks up an image corresponding to a vehicle number from the number plate of the vehicle. The radio card access system generates vehicle number plate data from the image picked up by the TV camera. The radio card access system compares the vehicle number data and vehicle number plate data and verifies whether or not the two sets of data coincide, the toll of the vehicle is calculated in accordance with the identification data stored in the storage medium.

Claims

1. A system for collecting a toll for a vehicle carrying a number plate and a storage medium, the storage medium stores radio identification data including vehicle number data, the system comprising:

means for receiving the radio identification data from the storage medium via a wireless transmission path;

means for obtaining plate number data including a plate number from the number plate;

means for comparing whether or not the radio identification data coincides with the plate number data wherein the radio identification data is received by the receiving means from the storage medium and the plate number data is obtained by the obtaining means from the number plate; and

means for calculating the toll of the vehicle in accordance with the identification data stored in the storage medium when the radio identification data coincides with the plate number data.

2. The system according to claim 1, wherein the obtaining means includes means for picking up the vehicle number plate data as an optical image.

3. The system according to claim 2, further comprising:

means for detecting a passage of the vehicle and generating a signal; and

means for activating the picking up means in response to the signal.

4. A system for collecting a toll for a vehicle carrying a number plate and a storage medium, the storage medium storing radio identification data including vehicle number data, the system comprising:

means for receiving the radio identification data from the storage medium via a wireless transmission path;

means for obtaining plate number data including a plate number from the number plate;

means for comparing whether or not the radio identification data coincides with the plate number data wherein the radio identification data is received by the receiving means from the storage medium and the plate number data is obtained by the obtaining means from the number plate;

first calculation means for calculating the toll of the vehicle in accordance with the identification data stored in the storage medium when the radio identification data coincides with the plate number data;

means for reading the identification data from the storage medium; and

second calculation means for calculating the toll of the vehicle in accordance with the identification data read by the reading means when the radio identification data differs from the plate number data.

5. The system according to claim 4, wherein the obtaining means includes means for picking up the vehicle number plate data as an optical image.

6. The system according to claim 5, further comprising:

means for detecting a passage of the vehicle and generating a signal; and

means for activating the picking up means in response to the signal.
