基于PCI总线的CAN—ARINC429实时监控卡软件设计与开发

摘要

In order to collect the data on CAN bus and ARINC429 bus in real time,this paper designs a PCI real-time monitoring card with CAN bus interface and ARINC429 bus interface.In the Windows XP/7 operating system,we adopt WDF driver to realize the communication between two CAN channels and two ARINC429 channels,and the test program was developed in C # language.This paper focuses on the design and implementation of the WDF driver,and analyzes the way of data storage and the error of timestamp in the application development process.Test results show that the circuit board and software can be accurate and stable operation for a long time.%为了能够实时的同时采集CAN总线和ARINC429总线上的数据,设计实现了一块同时具有CAN总线接口和ARINC429总线接口的PCI实时监控卡.在Windows XP/7系统下开发了基于WDF框架的驱动程序来实现了两路CAN通道和两路ARINC429的通信,并且用C#语言开发了测试程序.重点讨论了WDF驱动程序的设计以及实现,并对应用程序开发过程中的数据保存和时间戳的误差进行了分析讨论.测试实验结果表明该板块和软件可以长时间准确稳定运行.
