工控系统应用CAN总线的几种改进方法

Several Improved CAN Fieldbus for Industrial Application

实时现场总线CAN因其自身显著的优点,已广泛应用在工业领域中。随着分布式自动化系统复杂性一再增加,对网络范围和实时性的要求越来越高,传统CAN渐渐显露出它的局限性。本文讨论了对CAN总线的几种改进方法。它们不仅能提高CAN的性能,而且能兼容传统CAN总线。

CAN is a real-time fieldbus network which is wildly used in industrial environment because of its no-table features.With increased complexity of industrial distributed automation system,network extension and re-al-time communication become more and more important,and convenient CAN becomes dissatisfied.This pa-per present several improved CAN fieldbus for industrial application,which not only exhibits hig h communica-tion performance,but also ensures a hig h deg ree of compatibility with the existing devices and application developed for the conventional network.
