Smart Home Manage System Based On Ethernet And FPGA

Smart home is an intelligentized method that makes the habitation service, the matter management, the security and intelligent buildings together by effective transmitted network. It supports high-technology intelligentized method for overflow service and safe inhabitancy environment. And it will make all owners safer and more convenient.As the development of national economy and science technology, especially, the computer technology, the communications technology, the network technology and the control technology, smart home has been popularized quickly. At present, the structure of smart home is fieldwork bus such as Lonworks, FF and so on. However, the fieldwork bus technology is not mature enough .And the cost is too high. With the development of broad band Internet, it has become a direction to construct the smart home.This article presents a project of building an embedded smart home system based on Internet and FPGA. First, we build an embedded hardware system by a FPGA , some storage and some communications interface. Then we build a Nios II soft core CPU in FPGA, and transplant an uClinux operation system to the Flash storage. So the embedded operation system which has a full-function Web server, has been completed. After using the system as a control center, and adding some gather devices to it, we can build an embedded smart home system. It can complete many functions such as picture confiscation, timing picture gathering, real-time temperature measuring, broadcast, intelligent voice warning and so on.The smart home, which is based on embedded system, can be built easily. At the same time, the cost is very low. It is believed that the smart home system will have very high market potential.The paper is including: hardware design of the system such as circuit and PCB, design of the system CPU such as Nios II soft core and other peripherals, knowledge of embedded operating system uClinux and the transport method, software design of the system such as some CGI program and SCM voice program. In the end, it introduces some experimentation data and result.
