Development of Remote Operation System on Residential AC Power Supply Using Radio Frequency

Abstract

This paper deals with the development of a remote operation system for residential AC power supply using medium radio frequency transmission. Application of this system is to disconnect and reconnect the electricity supply which is operated by power utility company. Radio frequency (RF) remote control consists of a transmitter and receiver, which is the main module of the developed system. The transmitter will send a control signal through the module equipment transmitting antenna and the signal will be received by the antenna radio frequency transceiver module. Then, the recipient will control the electrical signals through the contactor as an interface with all electrical equipment. The operation of this system is at a fixed frequency of 315 MHz and distance control of electrical equipment is up to 10m at open space and subject to any restriction, antenna and supply of power. The results of this system are successfully demonstrated in the prototype of the remote control system for residential AC power supply. Some modifications have been proposed to improve the function of remote control system.
