This article particularly introduces the concept and study actuality of Embedded Internet. Through LWIP (Lightweight TCP/IP), Embedded Internet technology has been applied in the manufacture of the Embedded network communication equipment used in remote watch system for airplane equipment parameters. For realizing high reliability, low power consumption and cost, embedded system building blocks methods are adopted by using AT91FR40162 as its hardware's core and real time operation system core μC / OS - II in the original version of its software. It's laboratory sample having been realized, the equipment can be used in various fields on long distance data collection, data processing and transmission security.
