摘要
为了对机载信息系统各个设备的BIT信息进行实时检测和综合诊断,提出并设计了一套用于机载信息系统的维护自检系统;通过研究ARINC624标准规范,对维护自检系统进行层次设计、功能划分、整体架构设计、用户界面设计和容错性设计;通过对可能存在的应用场景进行分析、总结和仿真,验证设计方案的可行性、可靠性和安全性;实例仿真结果表明,系统在各个应用场景下都能对成员系统进行维护自检,并具有交互容错性。
In order to detect in real-time and diagnose synthetically for BIT information for each device onboard information system,a suit of maintenance self-test system for onboard information system is developed.By studying ARINC624 standard,system-level,function,overall architecture,user interface and fault tolerance of maintenance self-test system is designed.By analyzing,summarizing and simulating the possible application scenarios,verifying the feasibility,reliability and safety of the design.The simulation results show that the system under various scenarios can be maintained for member systems and interactive process has fault tolerance.
