- Can Bus Controller Area Network Of Technical Analysis Based On Field Bus Control System Technology Research And Application

Fieldbus is one of the best pop technology in control fields nowadays, which is the result of field control technology combined with modern electron computer communication technology. It is a kind of network, and can transmit numeric signal on two directions among many nodes , which is applied in buttom layer of industry control fields .According to these characteristics, fieldbus not only increases realibity anti-jamming of all control system ,but also can save greatly expense of investment installment and maintenance; Field facilities possess intelligence inter-linkage and mutual operation, which conduces development of fieldbus to decentralizations intelligence and network. In brief, the development of fieldbus and application of that must arose a profound change in industry control fields. This paper sets forth detailedly CANbus technology after introducing concisely Fieldbus technology, whose development future is very well. There are six parts in this paper .In the first part ,this paper givers a introduction to concept. background characteristics and development foreground of fieldbus control system; The second parts the third and the fifth mainly discuss characteristics technique criterion and status in application of CANbus . And two improvement methods are came out to solve real-time datum and non-real datum transmitted at one time on MAC child-layer of CANbus protocol. Finally, An example on CANbus technology is designed in the sixth part, which is applied in industry control fields.
