Development of New Smart Meter with Optimized Power Line Communication Module

Abstract

A smart meter was designed with power line communication (PLC) function. We designed the optimized power carrier module by adding a switching circuit that controlled by a microcontroller in coupling circuit on the basis of common design. Improved its communication efficiency and reduced energy consumption. Energy metering module used C8051F360 microcontroller as the main control chip and used high accurate metering chip ATT7022B to collect electronic signal. We designed a multifunctional and easy-to-use intelligent man-machine interface by using Beijing DWIN Company’s industrial serial LCD touch screen.
