飞控系统故障告警实时监控软件的设计与实现

摘要

为了对某型直升机电传飞行控制系统故障进行实时安全监控,降低试飞风险,分析了该系统的故障告警类型、故障判断方法和故障告警形式,根据飞行控制系统在飞行试验过程中的监控需求,以Labview为软件开发平台,开发了故障告警实时监控软件,以故障灯和文本信息显示的方式实现了对飞行控制系统各类型故障分等级实时监控与预警,并对软件实现方法进行了详细说明;在实际的飞行试验任务中,此软件能准确、可靠地实时监控到故障告警信息,完全满足飞行试验对飞控系统故障实时安全监控的需求.%In order to carry out real-time safety monitoring of a certain type of helicopter fly-by-wire flight control systems fault to reduce the risk of flight test,this paper analyses the fault alarm type,fault judgment method and fault alarm form of the system.According to the flight control system in the process of flight test monitoring requirements,based on the LabView software development platform,a fault alarm real-time monitoring software is developed to achieve the flight control system for all types of fault-level real-time monitoring and early warning in fault lights and text information,introducing the software realization method in detail.In the actual flight test mission,this software can accurately and reliably monitor the fault alarm information in real time,fully meeting the needs of real-time security monitoring of flight control system in the flight test flight.
