基于DSP的CAN_ARINC429接口转换设计

Design of the CAN_RINC429 Interface Transformation Based on DSP

ARINC429和CAN总线作为不同领域内重要的总线标准,各有特点,两个不同标准之间也存在着较大的差异。当所在的领域之间需要进行合作时,常常需要在两种不同的设备之间进行数据通讯和接口转换。通过对这两种串行接口标准进行详尽地分析和比较,介绍了一种采用基于DSP来实现CAN和ARINC429总线的转换方案,并对方案的设计方法及其特点进行了分析和说明。该方案在实际应用中得到了实时性,可靠性等方面的验证。

ARINC429 and CAN,as the important bus standards in different areas,have their specific features and their standards vary in different interface facilities.When the different areas work together,a data communication and an interface transfer are often necessary within different interface facilities.This paper analyzed and detailed the two serial interface standards,introduced a transformation project with a special method which was based on DSP to realize an interface transformation.The real-time ability and reliability of the project was validated in the engineering application.
