Design Of Distributed Control System Of Engine Based On CANbus

The fieldbus is the focus technology in 21th century that named as local network in automation fields . The fieldbus have been used in many fields , example industry control, transportation , robotic , digital machine , and so on . The automation system has goes into fieldbus control system . Based on the background of fieldbus , this paper introduce the fieldbus technology into design of Stirling engine control system . The distributed control system CAN based of Stirling engine has been designed . Better performances can be attained.In this paper, introduced the fieldbus technology at first, then explain the CANbus work principles . Based on these discuss , introduced the design of distributed control system CAN based of Stirling engine , including the design of hardware and the software based on real time operating system and CANopen protocol.This design has been produced , take long time experiment with Stirling engine . Experimental results show this design is correct and effective .
