A simple integrated smart green home design

Smart home systems were introduced to autonomously control appliances, lights and other services based on the current state inside homes. Smart home systems are designed for a wide band of applications such as healthcare, power management, safety and security. In Egypt, we are suffering from an electrical power shortage because the production is not sufficient for the actual consumption. In addition, there are some isolated areas not covered by the National Grid. Because of this persisting challenge, the need for finding solutions arose. Egypt is a developing country with limited resources, consequently economic and power saving focused solutions are needed. In this paper, a simple integrated design of a smart green house is introduced as a solution for a common Egyptian home to save the consumed power from the National Grid. This design has two main pillars: First, a smart system that controls the power consumption through monitoring the activity in the home to save the power as much as possible. This system comprises of a wireless network of controllers. Each controller monitors and controls a specific area considered a separate zone. These zone controllers exchange the current data and control parameters with a master unit, which provides supervision and control of the entire system. In addition, the system can be monitored and configured locally through a wall mounted touch screen or remotely using a mobile phone or web interface. Second, a solar power supply system equipped with a two degree of freedom sun tracker to partially or fully power the loads and hence reduces the power consumption from the National Grid. The solar system is integrated with the smart supervision system through a wireless link to the master unit.
