This paper introduced some kinds of methods of realization of Embedded-Internet. With these methods we can make the embedded device connected to Internet and control the device through Internet. In addition, this paper introduced long-range and distributed system of measurement & control based on Internet, introduced the structure and some key technologies of the system. We did some research on how to realize some key technologies, for example, flow control technology on the net, the embedded web server, the technology of making the instrument connected to the net. This paper also introduced the key device of flow control technology on the net, Bandwidth Controller of Ethernet, including design and realization of hardware and software. We simply described a kind of device , the gateway of Ethernet-CAN.Finally, we made pilot study about virtual instrument based on web and how to realize virtual instrument based on web in PC and embedded device. |
