Abstract: CAN (Controller Area Network) bus is a kind of field bus network which is mainly applied in field detection and control. Due to high reliability,real-time and low cost,CAN bus have a widely application in engineering detection and control field recently. Design plot of field detection system based in CAN bus was presented in this paper. It introduced configuration of hardware,flow chart of software and establishment of communication agreement. Practical measurement results indicate that the system has advantages in reliability, stability and extensibility.
