The embedded system and the control network technology has been applied more and more extensively in the modern industrial control.With the character of small size and high performace, low cost, high reliability, now embedded system has been applied in military, electronics, communication, industrial control and so on. The control network technology is the sign of the modern industrial control and it has promoted the development of the industrial control system. With the development of the embedded system and control network technology and by the use of the embedded specialized control network micro-system, and as the carrier of the embedded microprocessor and related peripheral equipments, constructing a new embedded network controller is the developing tendency of controller. The device of industrial automation based on the embedded chip technology has a deep developing space. Today many embedded controllers have been applied in the fields of industrial process control, numerical control machine, electrical power system, electrical network safety, electrical network device monitor, chemical system. In allusion to the demand of the embedded system and control network technology fastly developed, this topic introduces a design project of a network intelligent controller, which is based on MCF5272 microprocessor .This controller, cored with improved embedded uClinux operation system, merging large of new modularized integrated technology in embedded field, has excellent operability and expandability. Thus it can realize the field and network mixed measure /& control through integrating Profibus-DP and Ethernet interface. The intention of this topic is designing the embedded network controller which has the field and network integrated control function. The embedded network controller has integrated input /& output port and LCD display /& touch panel module, which can realize industrial field measure /& control. And it has integrated the f ieldbus and Ethernet interface, which has network distant measure /& control function. And it has transplanted the uClinux embedded operation system, which make controller has strong multi-function processing ability. This article firstly narrates the present researching status on the embedded system, control network technology and controller, as well as the meaning of this research and the key technology. And then introduces the whole project designment of the embedded network controller and the hardware framework. And then introduces the design of the controller' s hardware framework and debugging. Finally introduces how to transplants the embedded uClinux operating system and how to develop applicatioal realization. In a word, the article has completed the design of the embedded network controller and the transplantation of the embedded operation system, which provide the embedded platform for the subsequence development of the embedded network controller.
