Intelligent metering system

摘要

The present invention is an intelligent metering system for currency-activated devices having an electromechanical meter. The intelligent metering system includes an inductive pickup winding associated with the electromechanical meter. An amplifier is coupled to the inductive pickup winding to boost a signal detected from the inductive pickup winding when electromechanical meter is actuated. A pulse detector, coupled to the amplifier, detects pulses, false triggerings and filters out EMF spikes. A microprocessor is coupled to the pulse detector for counting the pulses detected by the pulse detector and for storing meter data related to the counted pulses in a memory device. An interface is coupled to the microprocessor for transmitting the meter data from the memory device.
