The Smart Three-Phase Electric Meter Based on ENC28J60 and MSP430F149
The electric meter is a direct tool by which power enterprise charges for electricity Tariff. This paper describes software and hardware designs of MSP430F149 SCM as the core control processor and smart remote transmission three-phase electric meter with the use of power collection special chip CS5460A to complete power measurement. This instrument integrates data monitoring and measurement of the power with LCD. And it can realize the functions of data remote transmission through communication connection between ENC28J60 chip and main controller and easily of real-time monitoring, data collection, system monitoring. This electric meter has some advantages such as powerful function, low cost, strong disturb-resistant ability, etc. and can meet the management requirement of the electricity energy intelligence, which is one of the main development trend in the future. This smart power data collection system will get a good application in the power industry informatization process .
