ABSTRACT:
A computerized parking meter uses an ultrasonic transducer to precisely measure the distance to a parked vehicle and to reset the parking meter to zero when the vehicle leaves. The computerized parking meter utilizes low power and may be recharged by solar power. The computerized parking meter can be programmed with differing rates, calendar days, advertising and alarms. Unlocking the coin box requires both the proper computer code and a key. When the computerized parking meter receives the proper computer code a solenoid is activated which retracts a plunger allowing the key to unlock the coin box. A coin discriminator allows only proper coins to be inserted into the meter. Audible messages and alarms can be sounded and written messages displayed. A portable terminal can communicate with a central computer to enhance collections security and identify repeat parking violators.
