Güç şebekeleri aracılığıyla akıllı cihazların uzaktan yönetimi

The tremendous demand for connecting devices to each other lead to the discovery of the term "Internet of Things" or IoT. Since then many more applications have been developed to provide Smart Home Systems and Home Automation Systems to make the users able to control, manage and monitor the home appliances remotely and to let a central device control another device at the same place. The development of smart devices led to the need for developing batteries that can handle such technology. These types of batteries use Lithium cells to save power and to provide the device with extended life duty. The studies show that abusing Lithium batteries can lead to damage to the cells. Overcharging is one of the reasons why Lithium batteries get damaged, a short circuit can bypass the safety methods inside the batteries and prevent them to work. Moreover, the Wi-Fi technology that is being used in many applications of Smart Home Systems has many disadvantages and security problems. These issues are compromising the Smart Home Systems, also make them unreliable to use. In this thesis, we developed a Smart Home System that uses the Power Line Communication to send and receive data from the appliances. It is node based; each node is distributed in the home depending on the need of each node. Each node can provide a different method and different type of usage. All the nodes communicate with each other through power lines, and a central controller will manage and monitor the nodes to make sure that they are working properly. We focus on developing a node that monitors and control an electrical socket. A charger connects to the socket to charge a Lithium battery. The developed algorithm will monitor the power line and determine when to cut the power off, so the battery will not be damaged by overcharging. Many factors will affect the decision of cutting the power off or reconnect it; this will depend on the environment and the current flow through the power line. A demonstration kit is developed to simulate all the possibilities that can affect this algorithm. The algorithm will monitor the flow, calculate the average of the current and keep records of these values. If the device starts to withdraw current more than the recorded average, that will indicate to a problem in the battery and cuts the power in the plug to prevent any farther damage in the device.
