Abstract
At present a world that people prefer automated systems rather than manual systems because of efficient, reliable and timesaving. Since the automated centralized electrical system is very expensive, most of the offices, hotels and industries are still controlling their decentralized electrical systems manually. In case of large organization, these manual decentralized electrical systems are very time consuming for controlling and furthermore the administrator of existing system could not identify the present status (On/Off) of the electrical devices. The proposed system consists of an electronic circuit which interfaces with a computer through the parallel port for timely controlling the electrical devices centrally using the database software. The proposed database software records the transactions about each and every devices, can estimate the total used time for a specific device. It includes internal memory for PC-free operation; control over 4,000 devices at a time; feed-through outlet won’t block from plugging in other devices; and provides easy trouble-free connection. This PC-based centralized system is very effective for the home, offices, hotels and industries in terms of cost and time for controlling the electrical devices.
