ARINC825总线模拟仿真与一致性测试方法研究

Research on ARINC 825 Bus Simulation and Conformance Test Method

随着航空电子设备技术的快速发展,高速、可靠的总线技术对于提高航空电子系统的整体性能和保证飞机的安全航行变得越来越重要。为满足飞机总装联调时对总线信号和总线测试的需求,设计了一套基于LabVIEW软件平台的机载ARINC825总线测试系统。系统基于美国国家仪器公司(NI)的工业化总线PXI平台。利用接口控制文档(ICD)建立XML格式的数据库,实现了ARINC825数据包生成、总线数据通信及一致性检测。经验证明,系统具有较高的可靠性和实时性,为ARINC825总线的模拟仿真及一致性测试提供了可靠的解决方案。

With the rapid development of avionics technology,high-speed,reliable bus technology is increasingly important for improving the overall performance of avionics systems and ensuring the safe navigation of aircraft.In order to meet the requirements of bus signal and bus test during the assembly and adjustment of the aircraft,we designed an airborne ARINC825 bus test system based on the LabVIEW software platform.The system is based on the National Instruments(NI)industrial bus PXI platform,using the interface control document(ICD)to create a database in XML format and achieve ARINC825 data packet generation,bus data communication and consistency detection.It has been verified that the system has high reliability and real-time performance,which provides a reliable solution for the simulation and consistency test of ARINC825 bus.
