摘　　要：现阶段国内直升机油量采集和显示系统的排故方式多采用系统联试,不能快速准确地定位故障。基于LabWindows/CVI设计开发了油量系统故障诊断测试程序,既可以单独测试系统中某一个部件,又可以系统联试。通过对串行数据的分析,均可以快速判定油量信号变换器或油量指示器的故障情况。该诊断方法易实现,有助于弥补现阶段直升机油量系统故障检测和修理手段的不足,具有一定的应用前景。At present acquisition and display of fuel system on domestic helicopter mostly adopts the system integration test,which can not locate the fault quickly and accurately.But based on LabWindows/CVI,the designed and developed test program for fault detection and repair of aircraft fuel system can not only test certain component separately,but also can do system integration test.Through the analysis of serial data,it can quickly locate the fault of fuel signal converter or fuel indicator.This diagnosis method is easy to achieve,and can help to make up the deficiency of fault detection and repair of fuel system at present.This method shows a certain application aspect.
