| Ethernet for industry as a new, uniform and fast developing standard, has been used widely in resource manage layer, executing layer and manufacture layer of industry corporation integrative automat nation. And it also trends to extend to the area of industry fieldwork control. The field-bus' actuality of multi-standard coexisting causes problems of the compatibility of product devices. This is also one of the problems that we must deal with immediately. So, Ethernet for industry fieldwork control will become a hotspot of the industry control.This paper discusses heterogeneous network interconnection engineering research– embedded protocol conversion module design and realization. In the embedded module Rabbit3700 foundation,.It can carry out the conversion between TCP/IP protocol and Modbus protocol.Firstly, we introduce actuality of field-bus's and Ethernet's. We also tell something about founding criterion of Ethernet for industry in the world.Then, we introduce some basic knowledge related to the work, they are: Ethernet and TCP/IP. And specify industry Ethernet timeliness and the Ethernet technology applied in the embedded system TCP/IP agreement simplification realization.In the last two chapters, we narrate the design of hardware and software, some diagram and soft coding are presented. In detail introduced the hardware various part of design method and the realization.In the fifth chapter, we tell the realization and debugging process in details and discuss some problems during debugging give solutions. And unifies Xinjiang Joinworld Co.LTD subsidiary company - electron aluminum foil company's rolling mill control system is the example, carries on the system application feasibility analysis and design.Finally, we summarize the paper, point out the deficient and what should be improved in the following work. |
