The Realization Of The Relationship Between Non-PC Devices And Internet

With the development of network era, Internet has become the most important foundational information establishment, so more and more devices need to be connected in Internet. If Non-PC Devices join up internet, information can be transmitted to all over the world, not only bring about the long range control, maintaining and updating of equipments, but also the equipments will change into apart of the internet sharing resources.There is a great deal of 8-bit or 16-bit low-speeded microprocessor in Non-PC Devices, when they access Internet, It is very difficult to implement full TCP/IP protocol due to its resource. The using Internet to control the equipment is first proposed in this paper, and then the necessity of the network in Non-PC Devices is emphasized. After that that several kinds of realizing methods of network in equipment are discussed, especially the micro controllers control network card to realize the transmission by Internet. On the basis of it, this paper puts forward the overall design idea, and designs hardware system and software system in detail. Theory of hardware system is gave, and principle of sending and receiving data of RTL8019AS are discussed importantly, and every layer of TCP/IP protocols stack and protocols being used such as ARP, IP, ICMP, UDP, TCP are analyzed deeply and in detail. Also in this paper, the difference of embedded TCP/IP protocol and standard TCP/IP protocol is pointed out, and flow charts of protocol and software design method. Finally, be proceeded the test of the system to the kind machine that research to manufacture. The testing results show that the ICMP protocol, UDP protocol and the most pivotal TCP protocol are realized well in this system. It shows that the data transmission on point-to-point structure is established, and Proof this text develops the usefulness of the result with the practical value. Can for the home electricity internet access, and the other embedded applies the long range control, long range of the system into the type according to collect etc. provide a kind of new good solution.
