BUILDING RELIABLE PROTOCAL BASED ON RESPONE PACKET IN PREPAID ELECTRICITY SYSTEM USING POWER LINE COMMUNICATION

Abstract

Power line communication is harsh and noisy transmission medium which significantly
deteriorate the transmission performance. The applications requiring reliable transmission
needs to give a protected data protocol across impulsive noise to ensure packet transferred to
receiver. The paper proposed a reliable protocol based on response packet in prepaid electricity
system. The author uses proposed protocol to construct softwares on website and smartphone.
The authors have completed the installation of the Data Concentrator Unit (DCU) and the
Switch Control Unit. Experimental results show that the DCU connects and gets data from the
server via GPRS service, sends and control remotely turning on/off process of the Switch
Control Unit via PLC with the successful transmission rate up to 93%. The proposed solution is
feasible with very low cost and suitable for Vietnam condition compared to system using
prepaid electricity metter.
