一种飞机TCAS电子系统故障诊断系统设计

摘要

通过对TCAS系统的常见故障的分析,采用工控机和凌华PCI-9812采集卡,使用防脉冲干扰滤波算法、离散傅里叶变换、特征提取、基于统计的贝叶斯决策方法和面向对象的决策树等,采用模块化设计方法,可在排故同时检测飞机存在的隐患,实现了以工业控制机为主机的TCAS电子系统故障诊断系统设计.通过仿真实验证明,该设计具有较强的可扩展性和维护性.%Based on the TCAS system common faults analysis, using IPC and Adlink PCI-9812 capture card, using the antipulse interference filter algorithm, discrete Fourier transform, decision-making based on Bayesian statistical methods and object-oriented decision tree, etc., modular design, This design methods can also detect aircraft in troubleshooting existing risks, and implement in industrial control machine for the host TCAS system fault diagnosis of electronic system design. Simulation results show that the design has strong scalability and maintainability.
