The Remote Control System Of Smart Home Based On LPC2220

With the popularization of PSTN and internet, for the rapid development of autocontrol and network communication technology, people is no more satisfied with the current habitat environment. The conception of intelligentization and informationization have been brought into the design of modern building. Smart home , melt with advanced autocontrol and network technoly, emerge in the mordern society.In this paper, a new solution for the remote control system for smart home is introduced by which people can control their home appliances through PSTN or Internet terminals remotely and conveniently. During the operation, the instructions will be sent to the main controller in the home network through PSTN or Internet. Then, the main controller will start to distribute the instructions to relative terminals to enable the appliances' centralized-control and thus make it possible to fulfill the remote control to the equipment and appliances inside the factory or house by multiple users in any place with the availability of the network. -The system is very simple to operate and expand; it can be applied to the smart-home and factory easily. The prototype of this system was tested and responded successfully, which verifies the feasibility of this system' s theory and concept.The remote control system is composed of three parts:1. PC software. PC software includes client software and server software.It' s function is to fulfill internet communication, to send the user instructions to PC server through internet, than transmit them to main controller by RS232C serial port.2. Main control circuit. Main control circuit includes main controller and DCE(Data Circuit-terminal Equipment)circuit. Main controller is the kernel of whole system, it manages the whole system. The function of DCE is to decode the data from telphone line then send them to main controller.3. Terminals. The control terminals are the self-study infrared controllers placed in each room, Then fulfill the instructions from main controller to control relative home appliances.
