Power line www.wineyard.in Data transmission and reception using power line communication : Data transmission and reception using Power line Communication. Domain : Embedded Systems Design Software : Embedded C, Keil, Proload Microcontroller : AT89S52 Power Supply : +5V, 500mA Regulated Power Supply Transmitter Display : 16 X 2 LCD Receiver Display : 16 X 2 LCD Receiver alert : buzzer Input Source : Key board Crystal : 11.0592MHz Communication Device : power line module(KQ330) Developed By : M/S Wine Yard Technologies Phone : 040-6464 6363, www.WineYard.in Hyderabad: Tarakarama Estates, 2nd Left Lane Opp RS Brothers, Ameerpet, Hyderabad – 500073 www.WineYard.in Ph: 040 – 6464 6363, 6625 6695, 888 5555 212 Title of the project Power line www.wineyard.in Data Security is primary concern for every communication system. There are many ways to provide security data that is being communicated. However, what if the security is assured irrespective of the hackers are from the noise. This Project describes a design of effective security for data communication by designing for data transmission. The source information is generated by a key board and this will be sent to destination through kq330(power line module) communication. The receiving system will check the data and displays on the LCD. The power line module communication used here are KQ330 Transmitter/Receiver, The transmitter stage must be carefully designed to take digital signals from the MCU, filter them to eliminate out of band emissions and drive the low impedance of the AC power line. In receiver section of the power line module receive the data through the power line communication module(KQ330) and send to the receiver section of the microcontroller unit and display on the LCD. This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer.
