ABSTRACT:
A low-powered electronic parking meter which can be powered solely by non-rechargeable, commercially available batteries. The meter includes a coin receptor with unique means for coin detection, slug detection, determination of coin denomination, and jam detection, which require very little power. The coin detection and denomination determination are performed using pivotable lever arms in contact with Piezo strips. The slug detection uses a permanent magnet mounted opposite a reed switch and the jam detection is performed by IR diode emitters and photocells. The meter also includes a processor, a liquid crystal display, a sonar transducer for detecting the presence of vehicles, and an IR transceiver enabling parking authority personnel to communicate with the meter. The components of the meter are operated in three conditions or states including an off condition, an inactive condition, and an active condition, to provide further conservation of power so that the meter is entirely battery operated.
