Distributed control system design based on CAN bus

摘要

Electromechanical system includes mechanism, control hardware and software. This paper proposes a college -stu- dent-oriented control system based on CAN bus, which includes flexible hardware and CSOS-based(CPU Sharing Operation System) software modules. As an easy-to-use, easy-to-learn, low cost and tiny-size control system, P89C58X2 is used as the main con- trol chip, LM629 is used as the DC motor controller, also sja1000 and tja1050 is used as the CAN controller and transceiver. At the end of the paper, an example of line-track robot using this control system is given to prove its feasibility.
