Design and implementation of internet of things for building electrical equipments

To realize the remote control and parameter monitoring of different electrical equipments, such as air conditioning equipments, lights and water pumps, etc., an Internet of Things for building electrical equipments is constructed and its network topology and functional structure are explored in this paper. In this Internet of Things, there exist three main functional blocks --- - the wireless measurement and control block, the room controller and the environment block. The issues on the self-organization and protocol of the wireless sensor network, which is used for information exchange in these functional blocks, are also studied. What is more, an equipment-management system, which can communicate with the room controllers via Ethernet, is provided on the management computer to realize the remote control of building electrical equipments. At last, an example is given to show how the electrical equipments can be connected to the Internet of Things and be controlled remotely.
