System Design And Network Forming Research Of Intelligent Home Based On USB Interface

With the development of society and the raising of peoples' living level, intelligent home will become an important symbol of future home and must get more and more applications. This paper presents a scheme which applies Embedded Technology and Universal Serial Bus (USB) interface to the system of intelligent home, characterized by real time, agility, high reliability, strong extensibility and so on.First, the essential conceptions, functions and ingredients of intelligent home are introduced. Secondly, it deals with the advantages of embedded and USB technologies in intelligent home system and gives pilot studies to embedded processor, embedded operation system and USB data transport protocols, followed by the hardware design of intelligent home system, including input information collection, output control, Liquid Crystal Display (LCD), the hardware and firmware design of USB. Next, the automatic monitoring for home system is realized by using the USB driver program in computer and the client application program, which are developed by "visual C++ language. Finally, it puts forward a right project of forming the network of intelligent home based on the investigation of setting up network theory.
