基于嵌入式系统的远程升级技术

如何利用以太网的高速带宽和优越性能实现网络互联，只有在统一的传输规则或通信协议的基础上开发产品的网络功能．通过远程升级技术实现嵌入式系统的自动升级改造。此处利用硬件来建立以太网的MAC层和物理层接口，实现了单片机与网络五连，既扩展了数据传输的功能，又保证了数据传输的正确性，同时也拓宽了数据传输的有效范围。

The Technology for the Remote Upgrade Based on the Embedded System

It becomes necessity trend of the development in electronic science and technology nowadays,that how to use the high speed bind width and the advantage of the Ethernet,and realizing connect each other on the Internet.None but based on the uniform transmit regulation or communication products,employed the function in network of the products.Through long-distance upgrade technology,it implements the upgrading and rebuilding in embedded system by self-motion.This article makes use of the hardware and builds up the ether net.It carries out a single chip machine and Internet successfully to connect with each other,since improves the speed of data deliver,and then guarantees the accuracy of data deliver,also expanding valid scope that data deliver.
