一种基于参数监控的自动驾驶仪故障检测方法
摘要：
本发明涉及飞机飞行控制系统技术领域，特别涉及一种基于参数监控的自动驾驶仪故障检测方法。故障检测方法包括如下步骤：通过检测模块实时检测飞机预定状态下的当前纵向参数和当前横向参数；通过数据对比模块将任务导航系统接收的当前纵向参数与给定纵向参数、当前横向参数与给定横向参数进行对比，得到纵向参数差值和横向参数差值；判断所述纵向参数差值以及所述横向参数差值是否超范围。本发明的基于参数监控的自动驾驶仪故障检测方法，通过判断所述纵向参数差值以及所述横向参数差值是否同时在预定值范围内，从而准确判断所述自动驾驶仪是否故障，确保安全。
摘要（英）：

The invention relates to the technical field of an aircraft flight control system and particularly relates to an autopilot fault detection method based on parameter monitoring. The method comprises a step of detecting a current longitudinal parameter and a current transverse parameter of an aircraft in a predetermined state through a detection module, a step of comparing a current longitudinal parameter and a current transverse parameter received by a task navigation system with a given longitudinal parameter and a given transverse parameter through a data comparison module and obtaining a longitudinal parameter difference and a transverse parameter difference, and a step of judging whether the longitudinal parameter difference and the transverse parameter difference exceed a range. According to the autopilot fault detection method based on parameter monitoring, through judging whether the longitudinal parameter difference and the transverse parameter difference are in a predetermined value range at the same time, whether an autopilot is failed or not is accurately judged, and the safety is ensured.
