Research on Real-time Monitoring Technique of Flight Data Recording System

针对飞机研制阶段各系统交联试验对故障定位慢、检查测试手段匮乏的问题,设计了飞参系统的实时监视功能;飞参系统中的机载设备与地面设备通过以太网进行数据交互,实现飞机状态的实时监视;分析了实时监视功能的作用与优势,并从某型飞参系统功能需求出发,阐述了机载设备的硬件配置及软件架构;基于UDP通信协议,提出了一种机载设备与地面设备交互的数据收发策略;该策略通过地面设备控制数据通信周期,机载设备采集的数据按周期发送给地面设备还原显示,实现了飞行数据的一边记录一边监视;实际应用表明,飞参系统的实时监视功能丰富了试验测试手段,提高了各个系统试验效率,实现了对飞机实时状态的监测,为航前快速检测技术的发展奠定了基础,具有很高的工程实用价值。

Real-time monitoring function of flight data recording system is designed to focus on the problem that being slow to locate the fault and lack of ways for detection in integration tests during flight platform development.Airborne equipment and ground equipment of flight data recording system exchange data through Ethernet,which realize real-time monitoring of aircraft condition.The effect and advantage of real-time monitoring function is analyzed.The hardware configuration and software architecture of airborne equipment is expounded which is based on the need of real-time monitoring function.A communication strategy between airborne equipment and ground equipment is proposed using UDP communication protocol.The period of data communication is controlled by ground equipment in the strategy and the flight data collected by airborne equipment is sent to ground equipment periodically,which can make flight data record and observe at the same time.The application of the strategy indicated that the function of flight data recording system enrich methods to test,improve the efficiency of each system test and realize real-time monitoring of aircraft condition.The method lay the foundation for rapid detection technology before flying and have the actual application value.
