Intelligent electric meter based on single chip microcomputer
Abstract
The accelerated pace of life of people to promote the emergence of more electrical appliances, which led to the increase in power consumption, as a result of the stability of the power supply network has brought a lot of adverse effects. In order to improve power efficiency, and actively respond to the challenge of environmental problems, improve the power supply of the timeliness and the quality of electric energy, improve services for power users, adapt to the rapid development of the electric power market, which for the development of the power grid is a more difficult challenge. This paper aims to study the design of intelligent electric meter based on 51 single chip microcomputer. The design based on 51 Series MCU is CPU as the storage and is compatible with the data processing core, and ADE7755 electricity metering module will transmits data to the CPU for processing, culminating in the LCD display output.
