The Research Of Distributed Control System Based On CAN Bus

Fieldbus is one of the hotspots of the development of automatization technology; it's looked as local computer network in the field of automatization. Its apperance is the symbol of a new age of industry control technology, and impacts the development of this field deeply.CAN bus is a kind of Fieldbus, it is one of the popular Fieldbus control system, and it is also the only Fieldbus which has national standard. Comparing to normal communication bus, the data communication of CAN bus has excellent characters of reliability, real-time and flexibility, and the strongpoint of Field bus.The reaserch of this thesis mainly aim at the technology of CAN bus of Fieldbus, and deplored a kind of aptitude field control interface and aptitude adaptor base on CAN bus. What's more, this thesis has discussed the problem involved deeply.
