在航電系統維護過程中，為解決定位故障的效率和降低維修成本等問題，提出了基于ICD（Interface Control Document，接口控制文件）的1553B總線的信息監控系統模型。該系統運用數據采集卡對總線中傳輸的信號有無失真、偏差等電氣特性進行檢測，并使用1553B通訊卡通過測控軟件LabWindows/CVI編程與ICD數據庫的動態鏈接，實現總線信息的解析和故障的判斷。與傳統的維護過程相比，這種模型能夠從信號的電氣特性以及信息的解析等全方位的去檢測判斷故障的來源，并且能夠廣泛在其他1553B總線系統內擴展應用。驗證表明該監控系統可以對總線信息進行快速有效地監測分析，能滿足應用需求。 Abstract: In the process of avionics system maintenance， to solve the problems such as improving the efficiency of fast orientation to troubles and reducing maintenance cost， system of 1553B bus information monitor model based on ICD was proposed.
