Research on Bus Communication Quality Based on Saber

The influence factors of controller area network(CAN) bus communication quality are studied in this paper, which provides a theoretical basis for improving the quality of CAN bus communication, and is conducive to the development and research of CAN bus. By analyzing the physical layer circuit structure of CAN bus, the physical layer simulation circuit is built by using simulation software. And the influence degree of components on signal quality is simulated and analyzed. In this paper, different topologies including star bus topology, topology, star topology, and star topology structure of physical layer circuit are simulated, the simulation results are compared and analyzed. The simulation results show that the parameters of the topology structure and the peripheral circuit, will affect the quality of CAN bus signal.
