Research And Development Of Server Based On 51-MCU

The intelligent device accessing Internet is a new developed demand when field-bustechniqueseeksuniform,anditispossibleforthenewdemandtomakefieldbustechniquebeunified by Ethernet technique, so it will become the technique direction to study embeddedEthernet equipment. The 51-MCU has a mature technique and is low in price and be usedwidely, so the research and development the 51-MCU server which can accessing internet isthethesis'spurpose.The paper analysis kinds of protocol about Ethernet. Ethernet protocol is quitecomplicated, so how to access 51-MCU which has little resource to Ethernet is this paper'shighlight. the paper has a hardware's development and study the work principle of networkinterface chip. besides, in the software this paper researches the implement methods of thesimplified TCP/IP protocol which is applicable for 51-MCU and other related protocol.Finally designs 51-MCU server successfully. It achieves the supervision and control for thedecentralizedtemperaturemeasurement andcontrol points accordingto1-wirebus, andit canform the Two Layer Architecture's and distributed measurement and control system. The51-MCU server designed works not only by C/S mode, but also by B/S mode. It implementsinformation's exchange between Ethernet and 1-wire. The experiment's result proves the51-MCUdesignedbythispaperissuccessful.In this paper, the control system to based on Ethernet and 1-Wire bus technology ofmonitoringmulti-pointtemperaturehasacertainamountofpromotionalvalue.Finally, the paper make a summary of this article and point out expectations of thefuture.
