Abstract

A parking meter includes a microcontroller and a timer coupled with the microcontroller. A mechanism for accepting payment by coin, credit card or both is coupled with the microcontroller for accepting payment for use of an associated parking space. The microcontroller initiates the timer for a prepaid parking interval upon receiving a signal from the payment acceptance mechanism. A vehicle detector is coupled with the microcontroller for detecting the presence or absence of a vehicle in the associated parking space. A communications modem is coupled with the microcontroller. The microcontroller initiates a call notifying authorities as to a parking violation upon the vehicle detector signalling to the microcontroller the presence of a vehicle in the associated parking space after the expiration of the prepaid parking interval.

Claims

1. A parking meter, comprising:

i) a microcontroller;

ii) a timer coupled with the microcontroller;

iii) payment acceptance means coupled with the microcontroller for accepting payment for use of an associated parking space, such that the microcontroller initiates the timer for a prepaid parking interval upon receiving a signal from the payment acceptance means;

iv) vehicle detection means coupled with the microcontroller for detecting the presence or absence of a vehicle in the associated parking space;

v) means for identifying a vehicle parked in the associated parking space, comprising digital camera means coupled with the microcontroller, said camera adapted to be focused at the associated parking space in the area of the parking space where the license plate of a parked vehicle is located, the microcontroller initiating the camera to take an image of a vehicle license plate upon determining the existence of a parking violation; and

vi) digital storage means for storing said digital image for subsequent retrieval or transmission.

2. The parking meter of claim 1 further comprising:

vii) telecommunications means coupled with said microcontroller, the microcontroller initiating a call notifying a remote monitoring station upon determining the existence of a parking violation.

3. The parking meter of claim 2 wherein said telecommunications means is adapted to transmit said digital image to said authorities.

4. The parking meter of claim 1 wherein said microcontroller comprises a microprocessor.

5. The parking meter as defined in claim 1 wherein said vehicle detection means comprises an ultrasonic detector.

6. The parking meter as defined in claim 1 wherein said vehicle detection means comprises an infrared detector.

7. The parking meter as defined in claim 1 wherein said vehicle detection means comprises radar.

8. The parking meter as defined in claim 2 wherein said telecommunications means comprises a modem.

9. The parking meter as defined in claim 1, wherein the microcontroller initiates the timer for a predetermined standby interval upon receiving a signal from the vehicle detection means that a vehicle is present in the associated parking space, wherein said microcontroller is adapted to terminate the timing of the standby interval upon receiving a signal from the payment acceptance means, and said microcontroller initiates the camera to take an image of a vehicle license plate after expiry of said standby interval without receiving a signal from said payment acceptance means that a payment has been made.

10. The parking meter as defined in claim 2, wherein the microcontroller initiates the timer for a predetermined standby interval upon receiving a signal from the vehicle detection means that a vehicle is present in the associated parking space, the microcontroller is adapted to terminate the timing of the standby interval upon receiving a signal from the payment acceptance means, and the microcontroller initiates a call to said remote monitoring station as to a parking violation after the expiration of the standby interval without receiving a signal from said payment acceptance means that a payment has been made.

11. The parking meter as defined in claim 1, wherein the microcontroller determines the existence of a parking violation upon the vehicle detection means signalling to the microcontroller the presence of a vehicle in the associated parking space after expiry of said prepaid parking interval.

12. The parking meter as defined in claim 2, wherein the microcontroller determines the existence of a parking violation upon the vehicle detection means signalling to the microcontroller the presence of a vehicle in the associated parking space after expiry of said prepaid parking interval.
