Abstract

In order to ensure the reliability of multiple nodes CAN bus in high frequency system, we need to find the design method of CAN bus. In this paper, we rely on the test platform to carry out tests and summarize the design method of elimination high frequency system.

Highlights

  • Controller Area Network(CAN) is a bus protocol which has been widely used in various industrial fields

  • In high frequency systems, due to the introduction of high frequency interference, it will lead to the serious decline of bus transmission quality

  • Delivery methods include: Conduction coupling, Common impedance coupling, and Radiation electromagnetic field coupling. ķ Conduction coupling 漡 It is the transmission of unwanted electromagnetic energy through a conductor

Summary

Introduction

Controller Area Network(CAN) is a bus protocol which has been widely used in various industrial fields. Compared with other networked control systems, the bus system can realize data transmission between nodes in distributed control system, more real-time and reliable. In high frequency systems, due to the introduction of high frequency interference, it will lead to the serious decline of bus transmission quality. We need to find a solution to high frequency interference, and verify its effectiveness. In this paper, building a high frequency system test platform. The main methods to solve the high frequency interference are tested. It provides a basis for improving the reliability of multiple nodes CAN bus in high frequency system
