SMART METER DATA TRANSMISSION THROUGH POWER LINE

Abstract

Power Line Communication is now become a popular technology for home automation, networking and data transmission. The aim of the project is to design a low-cost power line communication modem through which we can transmit or receive data on existing power lines. This PLC Modem is consisting of a modulator (Transmitter), demodulator (Receiver) and coupling circuit. The transmitter circuit is design for sending the signal to the power line. The signal modulation stage, the signal amplification stage, and the power line interface stage are all the stages for transmitter circuit design. The receiver circuit design is for receiving the modulated signal from the power line and recovering it to the original data signal. The interface with the signal amplification stage, and the signal demodulation stage are all for receiving circuit design. The objective of this project is to design and develop a low-cost Power Line Communication Modem Circuit to transmit data through power line (approx. 100 meter). Power Line Communication Modem includes transmitter and receiver circuits using latest Modulation Technique. A power line modem is an all-in-one device which consists of a modulator (Transmitter circuit), demodulator (Receiver Circuit) and a Coupling Circuits
