Design and research on intelligent electronic meters with hand transcribers

Abstract

The essay first establishes the general design scheme about software and hardware circuits of intelligent electronic meters with hand transcribers and elects the more advanced RN8209G multifunctional, anti-stealing, monophrase measurement chip as the energy measurement chip; then designs the main program flow chart of hardware and software in the systematic design scheme, such as the energy measurement chip, the current sample circuit, the voltage sample circuit, and hand transcriber, etc.
