Design of Smart Meter using Atmel 89S52 Microcontroller

摘要

Smart meter is a progressive energy meter that processes consumption of electrical energy and provides extra information compared to a conventional energy meter. Incorporation of smart meters into electricity grid includes execution of a variety of techniques and software, depending on the features that the state demands. Outline of a smart meter relies on upon the necessities of the service organization and the client. This paper talks about different peculiarities and advances that can be incorporated in a smart meter. In fact, arrangement of smart meters needs legitimate choice and usage of a communication system fulfilling the security measures of smart grid communication and proposes a design model for smart meter to know the exact billing that each load is going to consume with the help of wireless technology. The microcontroller takes the reading from the energy meter via an Opto-coupler and displays the reading on the LCD duly interface to a microcontroller. The reading of the energy meter is also sent to user through GSM modem being fed from the microcontroller via level shifter IC and RS232 link.
