Research On Application Of CAN Bus Control System

Controller Area Network (CAN) is a kind of serial communication network that supports the distributed control and the real time control. It has become a international standard about fieldbus due to its high capability and high reliability.In the paper,the elements and specification of CAN bus is dissertated. Discussion is made on the software function,the configuration of the control system and the hardware of the front-end node that takes the micro-controller 80C552 as its core. The design of a CAN based computer control temperature system is introduced.The simplicity and reliability of the design is verified in practice.
